AI Technical Summary

Technical Problem

Traditional hand restraints can impede blood circulation and cause nerve damage when used to fix the hand. They also lack flexibility and adjustability, making them difficult to adapt to different types of surgery and patient body types.

Method used

A surgical positioning fixation frame was designed, which adopts a positioning fixation component including a rack, gears and a connecting frame. The hand fixation position is adjusted by a motor-driven gear, and a uniform fixation force is provided by an airbag. A pressure sensor monitors and adjusts the pressure inside the airbag, and a control device adjusts the fixation parameters in real time.

Benefits of technology

It achieves stable fixation of the hand, improves surgical adaptability and flexibility, avoids the compression problems of traditional restraints, and ensures patient comfort and surgical safety.

Abstract

The utility model relates to the technical field of medical equipment, and particularly discloses an operative body position fixing frame which comprises an operating bed body, a control device, a buzzer, a timer and a body position fixing assembly. The two body position fixing assemblies are arranged on the two sides of the outer portion of the operating bed body respectively, and the body position fixing assemblies are used for fixing the hands of a patient; each body position fixing assembly comprises a rack, a gear and a connecting frame, the connecting frames do linear motion along the racks, and the fixing positions of the hands are flexibly adjusted; medical staff can flexibly adjust the hand fixing position according to the operation requirement, and the adaptability and flexibility of the operation are improved; uniform fixing force can be provided through inflation expansion of the air bag, and local compression and unsmooth blood circulation possibly caused by a traditional binding belt are avoided; medical staff can adjust the inflation volume of the air bag and move the position of the connecting frame at any time through the control device according to the actual situation in the operation process, and the same position is prevented from being pressed for a long time.
