Endoscopy medical pendant function

Endoscopy medical pendant is special type of endoscopic medical pendant. Generally it has 4 types: electric/mechanical, single arm/double arm, such as Mingtai D260 endoscopy medical pendant is mechanical single arm medical pendant.

Endoscopy medical pendant mainly has 2 functions:

1.      Works as media channel, gas is supplied through the medical gas terminal, 2 oxygen, 2 vacuum, 2 compressed air and 1 carbon dioxide; Besides those there are universal socket 3 holes × 8, 220V; 4 ground terminals;

2.      Works as device platform, instrument platform 5; drawer 1; infusion rod holder 1; injection pump rack 1; endoscope stent 1; tray 1, 1 miscellaneous goods basket, RJ45 network interface 1.

Endoscopic medical pendant is one of the essential surgical instruments in modern endoscopic surgery.

Internal camera system operating light handle component

Generally, internal camera system operating light handle component includes 4 parts:

1.      Handle, tubular shell, with internal gear in one end

2.      Fixed disk, outer ring fixed, inner ring can be rotated, installed in the handle, there are circuit board and light holder lift mechanism above the outer ring.

3.      Camera, installed in the handle, connected with the inner ring of the fixed disk

4.      Transmission, separate the camera and rotating mechanism through fixed disk, using the gear inside the handle and belt drive to link the rotation of handle and the light holder lift mechanism, therefor, when the handle is rotated to adjust operating light’s irradiation range, it can be avoided that moving camera angle.

Surgery lamp performance requirements

1.      Sufficient illumination

Now surgery lamp illumination can reach 180,000 Lux, near to the sun brightness in summer. The actual use of illumination generally is between 40,000 – 100,000 Lux, too bright will affect eyesight. Glare on surgical instruments should be avoided while providing adequate illumination, glare affects vision and vision, easy to make the eyes fatigue, adverse surgeon surgery. Surgery lamp illumination and operating room illumination should not have a big difference. Some standards require that the illumination of the overall illumination is one-tenth of the local illumination, the overall illumination of the operating room should be above 1,000 Lux.

2.      High shadowless level

Shadowless level is an important feature and performance indicators for surgery lamp. Any shadow formed in the surgical field will hinder the doctor's observation, discrimination and surgery. Besides adequate illumination, good surgery lamp also should have high shadowless level, to ensure that the surgical field surface and deep tissue have a certain degree of luminosity. Shadowless level test, use one 50X75mm black cylinder, put the light source 1M distance above it, place a photometer at the bottom of the cylinder, measured light and shadow ratio not less than 10%, the actual use of surgery lamp is installing a few or a dozen ring evenly arranged light source in 50-100 cm diameter lamp head, special bulbs and reflectors are used in the light source, the beam which from different points meets at one point through filter reflection, to provides balanced, uniform and shadowless bright beam.

3.      Low temperature

The improvement of illuminance will inevitably lead to the temperature increase of the lamp body and the beam, which will affect the temperature of the doctor head and the surgery field, thus affecting the operation efficiency and the operation quality. So the operating room temperature increase should less than 10 Celsius. The main way is to make the visible light generated by the light source through the filter which can filter out 70% infrared, most of the remaining infrared rays are separated and filtered by glass cover. After the above treatment the beam is called cold light.

4.      Good light quality

It means that the beam can truly reflect the blood, the organization's color and its changes. Generally, it is called color rendering. It is represented by the color rendering index which is calculated by the spectral distribution of light source. The best CRI is 100, CRI and color temperature have a great relationship. When color temperature reach 6000K, the true color rendering is about 70-90, the effective color rendering is close to 100.

5.      Operate easily

Surgery lamp should be able to continuously change the position and direction during the operation, the operation must be simple, flexible, lightweight, braking fast and effective. The central part of the lamp body should be equipped with sterilizable operating handle, some advanced products are also equipped with fiber optic deep cold light, color TV photography and ventilation devices.

6.      Economic and security

Economic mainly refers to the efficiency of light-emitting light, low power consumption and long life. As the surgery lamp structure is huge and complex, considering its safety is very important. This mainly refers to electrical safety performance, lamp body structure and its weight.

In recent years, in order to improve the light quality, Mingtai has developed and produced multi-layer dielectric film mirror which use hard glass as the reflective surface and infrared can through it, that is cold light reflector, it illumination more than 100,000 Lux. Reflector mirror coated multi-layer high-purity zinc sulfide, magnesium fluoride coating or titanium dioxide, silica coating in vacuum, coating uniform, free of impurities. In order to meet surgeon requirement, Mingtai equips brightness adjustment function in surgery lamp. Lighting angle can be changed according to surgeon’s position and surgical field range. Surgery lamp is developed on the direction of efficient, multi-function and economic, Mingtai company efforts to provides high quality surgery lamp with sufficient illumination, good color rendering, high definition and low infrared, to meet the need of modern surgery.

Electric operating table mainly feature

Operating table is mainly used to adjust surgery position, exposure surgical field make the surgery go smoothly. The position usually used in operating room includes 5 kinds: prone position, supine position, lateral tilt position, perineal position and sitting position. All bearings sealed waterproof, easy to clean. The water, bloodstains and suture head will not be wrapped in the bearings in surgery. Forward/backward tilt and lateral tilt can be adjusted by pressing controller, gentle, quiet and no vibration, and effectively protect the joint structure at the same time to prevent patients from dumping.

In accordance with the individual characteristics of the people, China's medical equipment industry standards require: table length 2M, width 0.48M, forward/backward tilt not less than 25 degree, lateral tilt not less than 20 degree. Head board down fold angle not less than 90 degree, waist bridge height not less than 0.12M. At the same time, industry standards also require that: operating table should try to use divided leg plate structure, divided leg plate can be rotated to the outside in the same level position, after the rotation angle of the legs of the inner plate is not less than 180 degree. Table board, all the adjustments are using stepless change.

Surgery lamp acceptance

Debugging usually includes below tips:

1.      Mechanical installation check

Check whether there are mechanical installation flaws, whether the screws is less or not tight, whether the circlip is stuck, whether each cover is covered well.

2.      Circuit check

First check whether the system is short circuit or open circuit, if everything is ok, power test can be done, check whether the external power supply is stable, whether transformer output voltage is too high or too low.

3.      Balance arm adjustment

Check whether the balance arm and the lamp head are matching, whether the balance arm force and angle should be adjusted.

4.      Joint flexibility adjustment

Mainly adjust the joint damping screws, the standard stipulates that the degree of tightness of the damping adjustment is close to 20N or 5Nm when push or rotate the joint at any position.

5.      Adjust and open joint limit switch

In order to facilitate the surgery lamp installation and transportation, most surgery lamp set lock switch or limit switch in its key components such as joints, now open it.

6.      Check the irradiation distance and depth

Most surgery lamp irradiation distance is between 70-140cm or 60-130cm, that means surgery lamp works best in this distance.

7.      Check illuminance and color temperature

Illuminance and color temperature are described for surgery lamp irradiation intensity. Usually the best surgery light is similar to sunlight, that is around 4300-4600K.

After those inspection the surgery lamp can be put into use.

Shadowless lamp safety

1.      Glass hood safety

Shadowless lamp glass hood is the nearest part to medical staff, in considering the premise of maximizing safety performance, Mingtai using the United States imported high-strength transparent explosion-proof plastic as the lamp glass.

2.      Light source safety

(1)   Most of Mingtai halogen shadowless lamps adopt Germany Osram halogen bulb, its average lifetime is 1,000 hours, its light source much closer to natural light.

(2)   Spare bulb switches automatically: when the main bulb is damaged, the spare bulb will switch automatically within 0.3-0.5 seconds, to guarantee surgery is not interrupted. There is indication on the control panel when then main or spare bulb failure, which reminds medical staff to replace them promptly after surgery.

3.      Electric part safety

(1)   Transformer is put in the base which is put on the ceiling, ensure that the accessible voltage is safe voltage.

(2)   Commutator use Germany commutator, electrical contact part will not produce sparks arising from the oxidation, the sparks will bring risks to operating room.

4.      Arm safety

360 degree universal design can meet different height, angle and position requirement during surgery, positioning accurate, convenient, no drift. Focus handle with non-slip design, can be disinfected with high temperature and pressure, maximize protect the safety of medical staff and patients.

Electric Operating Table Development Trend and Changes

1.      Electric operating table operation change

Electric operating table operation includes height adjustment, forward/backward tilt, lateral tilt etc. Early operating table is controlled by manual, not convenience and flexible; With the continuous development of Chinese medical device research and development capabilities, electro-hydraulic and hydraulic foot and many other light-driven mode has now been widely used. On the other hand, the development of electronic technology leads the pure electric operating table which is driven by motor to change the posture came into being. At the same time, these newly-developed new operating tables are gradually being replaced by far-infrared remote-controlled operating tables driven by pump motors without the electromagnetic interference. All in all, the operation of the electric operating table is becoming more and more automated and intelligent. The purpose of changing its operation mode has always been around to reduce the burden on the operator to facilitate remote control and meet the needs of surgery and other needs.

2.      Two major trends: multi-functional and specialization

Multi-functional is an important direction for the development of operating table, which is mainly based on the rational allocation of medical equipment resources. In parts of our country medical hardware construction is still in the development stage, it is not realistic to purchase specialized electric operating table for each department. This makes the generally electric operating table much highly respected. For example, Shandong Mingtai MT2000 series electric operating table is much suitable for head, neck, chest and abdomen, perineum, limbs and other surgical, obstetrics and gynecology, urology, ENT, thoracic surgery and many other departments surgery. Specialization and multi-functional In fact, not contradictory, at present, more and more hospitals are showing distinctive features, and equipping different operating table for different departments not only make the operation easier, but also more demonstrate the hospital's hard power. Such as gynecological hospital can choose Shandong Mingtai MT1800 series professional gynecological operation table; orthopedic hospital can consider purchasing MT2000 series operating table.

Hospital bed crank should be maintained?

Manual hospital bed crank is the necessary part for functional care hospital bed, in order to achieving different function, generally manual hospital beds are equipped with one or several cranks. Now there are 2 kinds cranks in Chinese market: one is crank with limit protection, another is crank without limit protection. Maybe someone is not familiar with limit protection, Shandong Mingtai company glad to explain it to you.

Firstly, we know that when we shake the crank, the hospital bed back board or other part will turn up/down or adjust height, continuous shaking will make the movement reaching this part’s designed limited position. For crank with limit protection, this part will stay in the limited position if you keep shaking crank; for crank without limit protection, it may be occurred that the screw fracture or this part deformation damage if you keep shaking crank when it reaches the limited position.

It is not uncommon for this situation to occur because of blindly hard or unclear usage in actual use, even may bring varying degrees secondary damage for patient in hospital bed, the hospital bed equips with limit protection crank can solve this problem, so we should know the crank configuration when we purchase hospital bed.

As an important part, crank is used more frequently every day, although Mingtai manufacturer has been commissioned and maintenance, in order to use normally and maximize its lifetime, it also need maintenance after using a period of time, clean up dust and debris on screw when you use it about 1 year, add the right amount of grease, regularly check the screws for looseness and tighten in time.
