Description

Laparoscopic surgery puncture knot tying training device

Technical field

The utility model is related to thoracic surgery medical instruments fields, are that a kind of puncture of laparoscopic surgery is beaten specifically Tie training aids.

Background technology

The Phillip Mouret of Lyons, France in 1987 complete world's the first Laparoscopic Cholecystectomy, alive immediately It is promoted and popularizes rapidly within the scope of boundary.Huge progress of the laparoscope as Minimally Invasive Surgical Technology, it has beauty, postoperative pain Pain is light, and operation wound is light, and interior environmental disturbances are slight, and the hospital stays is short, few the advantages that incisional hernia occurs.Nowadays the abdomen of thoracic surgery Hysteroscope technology has been widely used in clinical various Minimally Invasive Surgeries, and such as abdominal viscera biopsy, the broken top of liver, the renal cystis subtracts Art, gall-bladder, appendectomy etc. is pressed often to use laparoscopic technique.Laparoscopic technique usually need to make a call to 3~5 diameters in stomach wall For the hole of 5~20mm, disposes casing, casing to be respectively used to merging endoscope and observed in hole, be placed in various surgical instruments It is operated, such as intraperitoneal enteron aisle knots and sutures operation.Laparoscopic surgery and abdominal still have significant difference, it with pass The open surgery of system is entirely different, even if the surgical doctor clinically to know a thing or two, if not passing through training can not possibly carry out This operation.Laparoscope needs patient to perceive three dimensions depth by two dimensional monitors as a kind of surgical instrument And sense of orientation, such operation need to gradually be cultivated by specialized training.Especially in Urology Surgery laparoscopic use, have very much Operation related with kidney needs to establish peritonaeum outer operation approach under laparoscope, and there are many general surgery such as cholecystectomies Etc. operative approach in peritonaeum need to be established under laparoscope.In clinical practice operating process, the doctor that begins to learn laparoscope often with Due to lack of skill when operative approach is established in trocar (trochar) punctures, firmly unevenness, lacks experience, it may appear that through abdomen In film or through in musculature, injuring abdominal viscera organ, intraperitoneal nervus vasculairs cause organ damage, muscle damage, greatly The fortuitous events such as bleeding.And the knotting operation in laparoscopic surgery is as common surgical procedure, very test operation people Patience, skill and the operation transmitting-receiving of member, so to avoid the occurrence of such case or other complication caused by improper operation, state Inside and outside medical colleges and schools has used a variety of training modes and simulation trainer in clinic, the simple 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 instruction Practice etc..

These above-mentioned training methods are primarily present following two big problems：First, being lacked using simple training aids and training method It is weary not fine to the simulation of abdomen anatomy level or simulation degree.Abdomen anatomical structure level mainly divides skin, muscle, abdomen Four layers of film external fat and peritonaeum, and most of simple training aids are replaced with one layer thicker of soft material.Second is that imitative using computer True training aids, the higher training method such as zoopery operation training, such methods main problem are that trained cost is too high, Training equipment is expensive and such equipment is produced by foreign countries mostly, popularized in the cumbersome medical colleges and schools at home of training process difficulty compared with Greatly.And since the resident overwhelming majority is contact laparoscopic surgery training for the first time, basis shortcoming carries out such training adaptation Period is long.It resident at home or begins to learn in doctor's training of laparoscope at present, still lacks a kind of abdomen anatomy level Fine analog, training method is easy, at low cost, the cheap laparoscope puncturing operation operation training that can be commonly used of training Device.

Chinese patent CN202694651U discloses a kind of laparoscopic surgery and punctures knot tying training device by outer support at present Cover, abdominal tissues, internal organs composition, outer support cover are made of arc-shaped hollow outer cover and cuboid pedestal, front and back closing, in It entreats area there are six default puncturing hole, needs to select according to training, using arbitrary three holes being in triangular distribution, to be respectively implanted sight Mirror and laparoscopic surgical instruments are examined, abdominal tissues are attached at arc-shaped hollow outer cover inner surface, by simulated skin, muscle, peritonaeum External fat and peritonaeum composition, can fine analog human abdomen's anatomy level.

But it is practical to laparoscopic surgery puncture procedure not only for having in the gimmick of puncture, dynamics, direction and accuracy Very high requirement, on the other hand for puncture during the emergency situations that encounter be also required to timely association's processing, and To often also needing to carry out knotting operation in laparoscopic surgery practical operation, and laparoscopic surgery is all instructed without this with training aids The mode of white silk, and mechanism existing and above-mentioned at present is only to have carried out reality for the basic operation of laparoscopic surgery puncture procedure It is existing.

Utility model content

For above-mentioned deficiency in the prior art, the sequence of operations such as a kind of simulation of the utility model offer is punctured, knotted And there can be the laparoscopic surgery puncture knot tying training device of incremental training for the gimmick of knotting operation.

For the above technical purpose of realization, the technical solution of the utility model is:A kind of laparoscopic surgery puncture knotting instruction Practice device, including outer support cover and abdominal tissues, the outer support cover includes arc-shaped hollow outer cover and cuboid pedestal composition, institute State arc-shaped hollow outer cover on set there are six the default through-hole punctured, the abdominal tissues include the item filled with red liquid Shape water bag and rubber bag filled with gas, the arc-shaped hollow outer cover are slidably matched with cuboid pedestal, the abdomen group Knit further includes simulated skin layer, simulation muscle layer, simulated fat layer and peritoneal layer, the simulated skin layer, simulation muscle layer, mould Quasi- fat deposit and peritoneal layer are sequentially connected, and the bar shaped water bag filled with red liquid and the rubber bag filled with gas are located at In peritoneal layer, auxiliary piercing mechanism is installed on the through-hole, the auxiliary piercing mechanism includes pedestal and spherical parts, the ball Shape part is equipped with the hole for puncture, and the spherical parts coordinate with pedestal ball, and the pedestal is connect with through-hole.

Preferably, the through-hole is strip hole.

Preferably, being additionally provided with baffle made of multiple flexible materials on the cuboid pedestal.

Above description can be seen that the utility model and have following advantages：The laparoscopic surgery of the utility model punctures Knot tying training device is adapted to different level of student, and operates level according to different students, and different auxiliary is selected to wear The size in hole in the model and auxiliary piercing mechanism of mechanism is pierced, and can also be put according to the case where different students and demand The bar shaped water bag and rubber bag of different number and different location, the level and more simulation to continually strengthen puncture are true Patient profiles, while when without using auxiliary piercing mechanism, strip through-hole can simulate the surface of a wound, and a hole is probeed by knotting mechanism In carry out knotting training, a whole set of laparoscopic surgery simple structure for puncturing knot tying training device is of low cost, repair and replaces letter It is single.
