Description

Porous laparoscope simulation teaching aid

Technical field

The utility model relates to a kind of simulation teaching aid, particularly porous laparoscope simulation teaching aid.

Background technology

Laparoscopic surgery is the modern high technology operation that for medical skill, the sophisticated equipment such as electronics, optics principle completes, be traditional laparotomy ventrotomy across the epoch progressive, it is the operation of carrying out in airtight abdominal cavity, camera system is under good cold light source illumination, by being connected to Intraabdominal laparoscope body, Intraabdominal internal organs are photographed and are monitored on screen, under surgical doctor monitors, guides at high-tech display screen, outside abdominal cavity, handle operating theater instruments, to pathological tissues detect, coagulation, hemostasis, tissue separated with the operation such as incision, stitching.It is the model that electronics, optics, the contour science and technology of shooting are applied in clinical operation, have that wound is little, few intercurrent disease, safety, feature that rehabilitation is fast, deeply be subject to patient's welcome, especially postoperative scar little, meet aesthetic requirement again, young patient more gladly accepts, laparoscopic surgery is the general trend of surgery development and pursues a goal, at present, along with day by day improving and the raising of laparoscope doctor operant level of laparoscopic technique, nearly all operation can adopt this operation, and the effect in treatment surgical disease is more and more subject to attracting attention of people.

Laparoscopic surgery is one and is different from traditional brand-new surgical technic, except the difference of theory, equipment and operating theater instruments, the singularity and the complicacy that also possess skills and operate, laparoscopic surgeon, also must be through the systematic training of laparoscopic surgery technology except possessing sturdy open surgery basis.Existing laparoscope skill training device, is mainly divided into two kinds, and a kind of is virtual laparoscope training aids, high in technological content, involves great expense, and at present main dependence on import, trains doctor with this instrument, unrealistic; Another kind of be laparoscope training aids, more common in China, but fairly simple mostly in shape, training module is more single, debugs loaded down with trivial detailsly, and operation is inconvenient, falls flat.In fact being generally full of by organ in human abdominal cavity, and in the simulation teaching aid abdominal cavity existing at present much Spatial General 6 Rs be empty, be not inconsistent with actual conditions, can not embody intuitively actual clinical situation.And conventional laparoscopic surgery, needs to be first charged into the carbon dioxide of 3 liters of left and right in patient's underbelly, allows patient's belly fully expand, reserve operative space, existing surgical simulation teaching aid space is fixed, and internal organs stomach wall can not be out of shape, and cannot accomplish the exercise operation of " operation pneumoperitoneum ".

Utility model content

Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of porous laparoscope simulation teaching aid is provided.

The technical scheme in the invention for solving the technical problem is: a kind of porous laparoscope simulation teaching aid, is characterized in that: comprise simulation stomach wall, simulation waist and simulated organ; Described simulation stomach wall is elastic caoutchouc; Simulation stomach wall is provided with a plurality of apertures, and simulation stomach wall and simulation waist are flexibly connected; Simulation waist is simulation abdominal cavity with the cavity that simulation stomach wall surrounds, and sham operated apparatus extend in simulation abdominal cavity through the aperture on simulation stomach wall; In described simulation abdominal cavity, be provided with base, simulated organ, simulated blood vessel and nerve, simulated lesion place; Described simulated organ is rubber pouch, is connected with gas piping, and described gas piping is connected with inflator pump through the aperture on simulation stomach wall.

Above-mentioned simulation waist is rigid plastic.

Above-mentioned simulated blood vessel and nerve are many elasticity lines, on every simulated blood vessel and nerve, are equipped with tension pick-up, and described tension pick-up is connected with alarm by single-chip microcomputer.

Compared with prior art, the utlity model has following outstanding beneficial effect.

1, this teaching aid has effectively improved the validity of laparoscopically surgical operation simulation, the operating space of altitude simulation laparoscopic surgery and visual experience, for clinician trains and improves laparoscopic procedure technology and improved a good instrument, improved doctor's operative technique, for work is in the future laid a solid foundation.

2, on every simulated blood vessel and nerve, be equipped with tension pick-up, described tension pick-up is connected with alarm, and when sham operated apparatus is to simulated blood vessel and compression of nerves when excessive, alarm is brought into play warning function.Can help doctor to train oneself operating force, skillfully grasp the skill of operation technique.

3, described simulated organ is rubber pouch, simulated organ is connected with gas piping, described gas piping is connected with inflator pump through the aperture on simulation stomach wall, by simulated organ is inflated, make simulated organ be full of simulation abdominal cavity, thereby more meet with actual conditions, be convenient to the operation of intern's full course.
