Description

Simple laparoscopic surgery training device

Technical Field

The utility model relates to a laparoscopic surgery trainer especially relates to a simple and easy laparoscopic surgery trainer.

Background

The laparoscopic surgery has not only fast development speed, but also a single cholecystectomy in the surgical scope, which relates to the fields of multiple specialties such as hepatobiliary surgery, general surgery, obstetrics and gynecology, urinary surgery and the like, is popularized to primary hospitals at present. The problem of skill training in laparoscopic surgery is not well solved. Surgeons are used to open surgery for direct vision, while laparoscopic surgery is performed by using instruments by viewing two-dimensional planar images on a monitor screen, and not only lacks stereoscopic three-dimensional sense but also requires good orientation and hand-eye coordination of surgeons. In addition, beginners are not trained properly by looking and doing assistants. The teaching operation has limited opportunities, and the teaching operation has the defects of increasing the operation risk and prolonging the operation time.

It has been proved that the operation can be performed without trainingLaparoscopes will be very likely to cause surgical accidental injuries. Laparoscopic surgical training aims to transition surgeons from three-dimensional to two-dimensional operation and to train surgeons in the surgical ability to operate instruments through two-dimensional monitors. Traditional training models such as "black boxes" or "oxygen bags"_{The training effect is not ideal}The original set of laparoscopic instruments is needed, and the cost is high. The price of animal experiments is not too high. At present, the price of a laparoscopic surgery training box supplied by foreign markets is generally over $ 3000, and the training cost of the high-performance computer virtual reality applied to the laparoscopic surgery is more expensive.
