AI Technical Summary

Problems solved by technology

The existing traction frame has the following technical defects: 1. The traction position of the arm is fixed, but it is usually necessary to adjust the traction position of the arm during the operation, so the existing traction frame is inconvenient to adjust the traction position of the arm during the operation; 2. The traction force is controlled by heavy objects such as salt water bags, and the traction force control is not accurate

Abstract

The invention relates to a surgical traction rack for a wrist arthroscopy. The surgical traction rack for the wrist arthroscopy comprises a stand column and a traction device, wherein the traction device comprises a traction rope, a traction rope guiding wheel assembly and a traction force control mechanism, wherein a cross beam is arranged at the top end of the stand column; a fixing finger cot is arranged at the front end of the traction rope; the tail end of the traction rope is connected with a traction force control mechanism; the cross beam comprises a mounting beam and a front-back traction position adjusting beam; the mounting beam and the top end of the stand column are fixed; the front-back traction position adjusting beam slides in the length direction of the mounting beam to realize guiding fit; the front-back traction position adjusting beam is matched with a retractable driving device; the front end of the front-back traction position adjusting beam slides in the left-right direction and is matched with a left-right traction position adjusting slider; the left-right traction position adjusting slider is matched with a left-right adjusting driving device; the tractiondevice further comprises a traction force detecting sensor which is used for detecting and displaying a traction force; and a traction wheel assembly comprises a front end guide wheel and a middle guiding wheel set, the front end guide wheel is arranged on the left-right traction position adjusting slider, and the middle guiding wheel set is used for guiding the traction rope from the front end guide wheel to the traction force control mechanism. The traction position of an arm in a surgery process can be adjusted.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a traction frame used for pulling arms during wrist arthroscopic surgery. Background technique [0002] Arthroscopic surgery is surgery done with an arthroscope. An arthroscope is a rod-shaped optical instrument with a diameter of about 5 mm for observing the internal structure of a joint. It is an endoscope used by doctors to diagnose and treat joint diseases. This instrument has been popularized and applied since 1970. The arthroscope is equipped with a lens at the end of a thin tube, and the thin tube is inserted into the joint, and the internal structure of the joint will be displayed on the monitor. [0003] Therefore, structures inside the joint can be directly observed. Arthroscopic surgery is to cut several holes (5-10 mm) the size of "chopsticks" or smaller in the skin, and insert the camera and surgical instruments into the human joints. Under the monitori...
