Special retractor for hepatobiliary and pancreatic surgery

Abstract

The invention relates to the technical field of medical instruments, in particular to a special retractor for hepatobiliary and pancreatic surgery, which comprises a positioning frame and a retractor body, and the positioning frame comprises a positioning track, a displacement seat movably mounted on the positioning track, and a support mounted on the displacement seat. The retractor body comprises an adjusting assembly, an adjusting rod erected on the adjusting assembly and an operation hook body installed at the rod end of the adjusting rod, and the adjusting assembly is installed on the supporting frame through a steering assembly. The positioning frame is integrally designed on the outer edge of an operation cavity opening area, the operation hook body on the innermost side is used for supporting muscles in the cavity opening area, no related parts are blocked at the cavity opening position, and therefore interference cannot be generated on the operation of a doctor, and the operation smoothness is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special retractor for hepatobiliary and pancreatic surgery. Background technique [0002] In the known technical field, at present, when performing medical operations on patients clinically, it is generally necessary to open the cavity for easy operation, especially in the face of hepatobiliary surgery, because there are many organs involved, it is often necessary to install multiple surgical devices. The retractor opens the chest cavity of the human body, which is not only very cumbersome to operate, but also time-consuming and labor-intensive, which brings a lot of pressure to the treatment time, operation time, and patient's ability to bear. [0003] The main structure of the existing pull hook device is a fixed frame, an adjustment plate is arranged inside the fixed frame, a threaded hole is opened on the top of the adjustment plate, and a threaded rod is connected ...

[0002] In the known technical field, at present, when performing medical operations on patients clinically, it is generally necessary to open the cavity for easy operation, especially in the face of hepatobiliary surgery, because there are many organs involved, it is often necessary to install multiple surgical devices. The retractor opens the chest cavity of the human body, which is not only very cumbersome to operate, but also time-consuming and labor-intensive, which brings a lot of pressure to the treatment time, operation time, patient's ability to bear, etc.

[0003] The main structure of the existing pull hook device is a fixed frame, an adjustment plate is arranged inside the fixed frame, a threaded hole is opened on the top of the adjustment plate, and a threaded rod is connected to the internal thread of the threaded pipe, and the left end of the threaded rod extends to the threaded rod. There are pull hooks on the outside of the tube, and it is fixedly connected; however, this structure has certain defects. The threaded rod and the installation carrier are arranged above the open cavity area, which has a certain impact on the operation of medical staff
