Description
Technical field:
This utility model relates to technical field of medical instruments, is specifically related to a kind of splanchnocoel videoendoscopic surgery apparatus
Background technology:
Splanchnocoel videoendoscopic surgery is the Minimally Invasive Surgery method of an emerging development, because its operation wound is little, to surrounding tissue, damage drops to minimum, and the reparation of patient's postoperative wound is compared to traditional open surgery have obvious advantage, increasing doctor and patient select splanchnocoel videoendoscopic surgery to treat.In existing splanchnocoel operating theater instruments, blade part damage frequency is apparently higher than handle portion, yet one is its cutter head service life in the service life of splanchnocoel videoendoscopic surgery apparatus.Although the apparatus kind of required use in common endoscope-assistant surgery is 4 to 5, Dan Yisuo hospital need to be equipped with complete all cutter heads, needs to purchase different 46 kinds of endoscope-assistant surgery apparatuses.This has not only caused the waste on raw material, has also increased to a certain extent hospital and has purchased the expense of apparatus, and then increased treatment cost, has increased the weight of the medical treatment burden of sufferer.
Utility model content:
The purpose of this utility model is to provide the splanchnocoel videoendoscopic surgery apparatus of head-exchangeable, and it can pass through dismounting and the replacement of cutter head, when guaranteeing even to extend cutter head service life, reduce the replacement frequency of handle of a knife, thereby reach saving material, save hospital's spending, the effect that alleviates sufferer burden.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises handle, cutter head, the top of handle is connected with cutter head, described cutter head comprises bar in jaw, the outer bar of cutter head, cutter head, the outer masthead end of cutter head is provided with jaw, and the outer bar of cutter head inside is provided with bar in cutter head; Described handle comprises bar, bar knob, lever in the outer bar of handle, handle, and the outer bar front end of handle inside is provided with bar in handle, and the rear end of the outer bar of handle is provided with bar knob, and the rear end of bar knob is provided with lever.
Operation principle of the present utility model: tool bit part jaw is closed, handle portion lever is adjusted to proper angle, two cylinders of localizer are snapped in respectively to grip two holes, handle position is fixed to proper angle, be threaded connection to coordinate cutter head is installed, stretched in the hole of having accomplished fluently on patient chest abdominal cavity, action bars knob and lever are performed the operation.
The utlity model has following beneficial effect: it can pass through dismounting and the replacement of cutter head, when guaranteeing even to extend cutter head service life, reduce the replacement frequency of handle of a knife, thereby reach saving material, save hospital's spending, the effect that alleviates sufferer burden.
