Description

A lower limb fracture traction frame

technical field

The utility model relates to the technical field of medical devices, in particular to a lower limb fracture traction frame.

Background technique

When the fracture occurs in the patient's lower limbs, it is necessary to perform traction on the patient's lower limbs after surgery and operation, so as to avoid the blood vessels and nerves around the fracture end stabbing due to the movement of the fracture site, which makes the patient more painful. At the same time, when disinfecting the patient's lower limbs, The patient's lower limbs need to be lifted to facilitate all-round disinfection of the patient's lower limbs.

During the disinfection process, the lower limbs of the patient are generally lifted by the medical staff or supported by the Y-shaped frame, and then disinfected, but the manual lifting by the medical staff will cause the lower limbs to move due to uneven force, and it is supported by the Y-shaped frame. Need to be required to operator's operational proficiency when needing to some extent, so in publication number: CN210644494U a kind of lower extremity fracture operation disinfection traction frame by foot fixation band and the matching assembly to the fixed position of foot fixation band, reached simple in structure, It is firmly fixed, safe to use, easy to clean and disinfect, and solves the existing problems of traction on the lower limbs of patients and uneven force. However, the above-mentioned device still has the following disadvantages and problems:

1. Since the foot fixation belt can only limit the height of the patient's lower limbs, it cannot avoid the shaking of the patient's lower limbs during the disinfection process and cause the patient's fracture site to receive secondary injuries;

2. The fixing device for fixing the traction frame to the side of the bed is set on both sides of the bed. During the process of fixing it, when one person is fixing it, the traction frame cannot be fixed in the center of the bed. When supporting the patient's foot, it is very troublesome to open the rotating buckle and move it to the corresponding position of the patient's foot;

Therefore, we propose a lower limb fracture traction frame.
