Description

A kind of laparoscopic surgery puncture procedure training aids

Technical field

The utility model relates to medical skills training technical field, is a kind of training aids that is applied to laparoscope technology operation training in the clinic.

Background technology

The Phillip Mouret of Lyons, France in 1987 has finished the first Laparoscopic Cholecystectomy in the world, worldwide is promoted rapidly immediately and popularizes.Laparoscope is as the huge progress of Minimally Invasive Surgical Technology, and it has beauty treatment, and postoperative pain is light, and operation wound is light, and interior environmental interference is slight, and the hospital stays is short, and the advantages such as incisional hernia seldom occur.Nowadays laparoscopic technique has been widely used in clinical various Minimally Invasive Surgeries, such as the abdominal viscera biopsy, and liver, the broken top of the renal cystis decompression, gall-bladder, appendectomy etc. often adopt laparoscopic technique.Laparoscopic technique usually needs to settle sleeve pipe in the stomach wall hole that to make a call to 3～5 diameters be 5～20mm in the hole, and sleeve pipe is respectively applied to insert endoscope and observes, and inserts various operating theater instruments and operates.But laparoscopic surgery and abdominal still have significant difference, and it is fully different from traditional open surgery, though the surgical doctor that knows a thing or two clinically, if can not carry out this operation through training.Laparoscope needs the patient to pass through two dimensional monitors and the perception three dimensions degree of depth and sense of orientation as a kind of surgical instrument, and this kind operation needs progressively to cultivate by specialized training.Especially in the Urology Surgery laparoscopic use, there are a lot of operations relevant with kidney need to set up peritonaeum outer operation approach under the laparoscope, there are again many general surgeries such as cholecystectomy etc. need set up under the laparoscope operative approach in the peritonaeum.In the clinical practice operating process, begin to learn laparoscopically doctor often when setting up operative approach with trocar (trochar) puncture because lack of skill, firmly uneven, lack experience, can occur injuring the abdominal viscera organ through in the peritonaeum or through in the musculature, the intraperitoneal hemorrhage pipe is neural, cause organ damage, muscle damage, the fortuitous events such as massive haemorrhage.Be other complication of avoiding this situation occurring or being caused by improper operation, medical colleges and schools is in clinic both at home and abroad, multiple training mode and simulation trainer have been used, the simple and easy black box training aids of reflective mirror, laparoscope black box training aids, Computer Simulation training aids and orientation operation training, synthetic operation training, zoopery operation training etc.But mainly there are following two large problems in these training methods: the one, and use simple and easy training aids and training method to lack not meticulous to simulation or the simulation degree of belly anatomy level.Belly anatomical structure level mainly divides skin, muscle, and four layers of peritonaeum external fat and peritonaeums, and most of simple and easy training aids replaces with the thicker soft material of one deck.The 2nd, use the Computer Simulation training aids, the higher training methods such as zoopery operation training, this class methods subject matter is to train cost too high, and exercise equipment costliness and this kind equipment are popularized difficulty larger mostly by external production in the loaded down with trivial details at home medical colleges and schools of training process.And because the resident overwhelming majority contacts for the first time the laparoscopic surgery training, the basis shortcoming is carried out this type of training adaptation cycle long.At present at home the resident or begin to learn in laparoscopically doctor's training, still lack the meticulous simulation of a kind of belly anatomy level, training method is easy, the training cost is low, the laparoscope puncture operation technique training aids that low price can generally be used.

Summary of the invention

The purpose of this utility model provides a kind ofly can better simulate belly anatomy level, and training method is easy, and the training cost is low, low price and the laparoscopic surgery puncture procedure training aids that is easy to apply.

The utility model is by the outer support cover, abdominal tissues, internal organs form, the outer support cover is made by tempered glass, the main fixedly abdominal tissues that rises, form the effect in abdominal cavity, in order to avoid when the puncture stomach wall, cause abdominal tissues to inter collapse, the outer support cover is connected with base by two loose-leaves on the side base, the outer support cover is opened and closed, conveniently to pick and place the article of the inside, default six puncturing holes on the outer support cover, any three holes that are in triangular distribution according to the training need choice for use, abdominal tissues is made of four layers of sponge, simulated skin layer successively from outside to inside, muscle layer, peritonaeum external fat layer and peritoneal layer, abdominal tissues is identical radian and is attached at the outer support cover inner surface with the outer support cover; Internal organs are by soft material such as rubber hose, the compositions such as balloon, be intended to simulate the abdominal viscera organ, place on the rectangular parallelepiped base, identical with the human organ ratio, shape is close, and simulation is strong, base is made by thick plastic plate, and linking together by loose-leaf with the outer support cover consists of airtight abdominal cavity model.

In six default puncturing holes, select any three perforates of the required distribution triangular in shape of operation during use, cut successively separate skin layer, muscle layer, peritonaeum external fat layer three-layer weave with scalpel in a perforate therein afterwards, then with the trochar peritonaeum that carefully punctures, take out the sleeve pipe inner core, sight glass is put into the abdominal cavity along sleeve pipe; Two other puncturing hole carries out puncture procedure under the supervision of sight glass, after trocar puncturing is finished, insert corresponding laparoscopic surgical instruments; In trocar puncturing and insertion process, as injure internal organ and other tissue, can under sight glass, see or make the internal organ explosion of balloon simulation, remind operation to produce damage, reach training goal.

The utility model is simple in structure, and is easy and simple to handle, and simulation is strong, and the training flow process is simple, and cost is low, makes the resident or begins to learn laparoscope doctor laparoscope grounding scale, and normalization becomes possibility.
