Description

Liver drag hook fixed bolster

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a liver drag hook fixed bolster.

Background

Liver diseases are common diseases of general surgery, including hepatobiliary calculus, hemangioma, liver cancer and the like, and mostly require surgical treatment, and doctors often need to use instruments to pull and expose the liver during surgery so as to obtain a clear surgical field and manipulate other surgical tools in a larger area. At present, in order to obtain a clear surgical field, the operator usually pulls the liver with a retractor to expose the surgical field. But because the hook plate operation that uses at present is inconvenient, lacks and carries out all-round and the fixed support of various angular adjustment with the drag hook, and this needs many medical personnel to mutually support when just making current liver drag hook use and realizes the position control of the not equidirectional of drag hook, makes current liver drag hook operate more loaded down with trivial details like this, can not carry out multi-angle tractive with the liver, consequently, is not convenient for the doctor and observes the condition of the wild liver cover part of art.

In order to solve the problems of the prior art, people have long searched for and put forward various solutions. For example, chinese patent document previously filed by the applicant discloses a liver retractor and its assembly [ application No.: 201220359078.9], the liver retractor comprises a retractor arm, a retractor rod and a retractor body, wherein the retractor rod and the retractor body are respectively arranged at two ends of the retractor arm, and the retractor body is formed by extending from one end of the retractor arm along the direction far away from the retractor arm. Liver drag hook subassembly, including this liver drag hook and fixed this liver drag hook, can all-round, arbitrary angle pivoted fixed establishment, this fixed establishment can be dismantled fixedly with the drag hook.

Above-mentioned scheme has solved current liver drag hook to a certain extent and has needed the artifical problem that just can realize the multi-angle and fix, but because what adopt in this scheme is that multistage connecting rod rotates the mode that links to each other, produce phenomena such as fixed insecure easily between two adjacent connecting rods, just so lead to the drag hook to be not enough at the liver in-process pulling force easily, produce the aversion phenomenon easily, and simultaneously, because multistage connecting rod rotation links to each other, when needs adjustment drag hook position direction, it is inconvenient still to have the adjustment, the problem of excessively loaded down with trivial details of operation.
