Laparoscopy Apparatus High Temperature And High Pressure Sterilization Method
Oct 12, 2017

Laparoscopy Apparatus, high precision, complex structure, is a collection of modern electronics, optics and mechanical and other aspects of a comprehensive system, so the daily Laparoscopy Apparatus for good maintenance is particularly important. Good maintenance is not only to extend the life of laparoscopy, reduce maintenance costs, but also reduce the incidence of intraoperative failure is an important prerequisite.

1, the composition of laparoscopic surgical equipment

Laparoscopic surgery is a combination of several devices, only a clear understanding of the function and characteristics of each device in order to timely find the problem and solve the problem. A complete set of laparoscopic surgical equipment is usually composed of the following five parts: ① display camera system, including the display, laparoscopic lens, mirror tube, signal converter, its function is used to capture and show the body cavity clear, realistic image ; ② cold light source system, its function is to provide lighting for surgery; ③ pneumoperitoneum, its function is to provide adequate space for surgery; ④ high-frequency electric knife, including unipolar and bipolar, its function is to implement the cut target; The negative pressure suction system, including the suction tube, attracts the pipe, attracts the bottle, its function is to attract the excrement and the intraoperative flow of the tissue fluid.

2, Laparoscopy Apparatus in the operation of common faults and their removal program

(1) black screen phenomenon: the display, cold light source system power connector, camera line connector off, cold light source system bad contact and damage to the lamp and other reasons will cause the display black screen phenomenon. Therefore, the equipment should be carefully checked before surgery, and standing cold light source system replacement lamp.

(2) the image is not clear: the camera focal length deviation or foreign matter on the lens can cause the image is not clear, fine-tuning the focal length or wipe the lens with iodine cotton swab to solve such problems.

(3) image shade disorders: surgery in the surgery between the light can not be too bright, should close the shadowless lamp, the cold light source transferred to the automatic position, otherwise it will cause the image is too bright. And the image is too dark may be caused by two cases: ① cold light source guide beam and laparoscopic connection loose or cold light source connection slightly loose, as long as the connector slightly forward, the light source can be restored positive system "; ② lighting fiber Part of the broken wire, as long as the replacement of all the optical fiber can be resolved.

(4) Image color imbalance: The wrong setting of the camera's white balance will cause the image color to be distorted, so it is necessary to set the white balance automatically or manually before using the camera system.

(5) fog as the phenomenon: the casing into the abdominal cavity before the need for preheating, so that the temperature exceeds the human body cavity temperature to avoid fog, the laparoscope into the 40 ℃ saline preheat for about 5 min The

Single-hole laparoscopic multi-channel device, that is, in the abdomen cut a small mouth, through the device into and out, such as laparoscopic lens, separation clamp, electric hook, clip clip and other different surgical instruments to complete the operation.

The existing laparoscopic technique for porous operation, although more lumbar surgery minimally invasive, but single-hole laparoscopic technique more holes are more invasive In a hole through a number of instruments to complete the operation, its advantages in the performance of only about 1 cm about 2 cm in the umbilical more subtle, after healing the basic appearance can not see. Postoperative incision pain is lighter, faster recovery. Based on the above advantages, the patient is happy to accept. Tertiary hospital gradually carried out, single-hole laparoscopic technology in recent years more and more mature, single-hole multi-channel device for the one-time supplies, the market demand is very large.

Cleaning of Laparoscopy Apparatus: Immediately after surgery, remove the removable part of the laparoscopic device and clean it. First with the enzyme soak, and then rinse with flowing water. With the lumen of the device, after each use should be used through the brush through the brush, and then repeated washing with water or high pressure water gun. Use a cotton swab to clean the valve chamber, spring, seal and puncture cone side hole, dry after the valve in time to restore the valve to avoid the loss of small parts. Clean the gripping device and scissors should open the rotating shaft and gently scrub. If the stub is still stubborn debris is cleaned with ultrasonic cleaner. Camera, laparoscopic angle with a soft cloth to dry dry, avoid using a rough cloth towel to avoid scratching the lens, is strictly prohibited using ultrasonic cleaning machine for endoscopic cleaning.

Laparoscopic device disinfection: for different devices can be used high temperature and pressure sterilization method, low temperature sterilization method for disinfection. Camera, cable and electrode can not use disinfectant soaking or high temperature autoclaving disinfection, otherwise the equipment will cause serious damage, can only use gas fumigation or plasma low temperature sterilization method.
