Retractor for abdominal surgery

Abstract

The invention discloses a retractor for abdominal surgery. The retractor comprises a supporting mechanism, and a retracting mechanism. The supporting mechanism consists of a fixing clamp, supporting columns, a base, an annular supporting frame, a sliding block, and a limiting bolt; and the supporting columns are symmetrically arranged at the bottom of the base. The retraction mechanism consists of a supporting seat, a first fixing block, a sliding rod, a rack, a second fixing block, a connecting piece, a drag hook, and a sliding groove; the supporting seat is connected with the outer side wall of the annular supporting frame; and one end of the sliding rod penetrates through the interiors of the first fixing block and the second fixing block, and is connected with the drag hook through the connecting piece. According to the retractor for abdominal surgery, the annular supporting frame is arranged so that a worker can manually rotate the annular supporting frame to adjust the drafting direction of the drag hook; and moreover, the limiting bolt is arranged so that the worker can fix the connecting position of the annular supporting frame and the base by rotating the limiting bolt, thereby facilitating prevention of retracting direction change of the drag hook in the process of wound retracting.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a retractor for abdominal surgery. Background technique [0002] Retractors, also known as retractors, are used to retract tissue, reveal the surgical field, and facilitate exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. Retractors are available in various shapes and sizes. To select a suitable retractor, when performing abdominal surgery on a patient, it is necessary to use the retractor to stretch the abdominal wound, so as to fully expose the field of view suitable for surgery, so as to facilitate the operation of the doctor. Most of the existing retractors have poor flexibility, it is inconvenient to adjust the retraction direction according to the shape of the wound, and it is not convenient to use. To adjust, in view of the above problems, the existing equipment needs to be improved. SUMMARY OF THE...

Problems solved by technology

[0003] The purpose of the present invention is to provide a retractor for abdominal surgery, to solve the problem that most of the existing retractors proposed in the above background technology have poor flexibility, and it is inconvenient to adjust the retraction direction according to the shape of the wound. It is not convenient to use, and on the other hand, most of the existing retractors have complex structures, which makes it inconvenient to adjust the degree of retraction
