Bone traction instrument facilitating angle adjustment

Abstract

The invention relates to a bone traction instrument facilitating angle adjustment. The bone traction instrument comprises a combination portion fixed beside a bed and a first fixing frame connected with the combination portion. The bone traction instrument is characterized in that the first fixing frame comprises a base with good stability, a first vertical telescopic structure and a rotating wheel, wherein the first vertical telescopic structure is arranged at the upper end of the base, the height of the first vertical telescopic structure can be adjusted, the first vertical telescopic structure can be locked, and the rotating wheel is arranged at the upper end of the first vertical telescopic structure and facilitates placement of a traction wire; an adjusting portion used for adjusting the height of the first vertical telescopic structure is arranged at the upper end of the base; the adjusting portion comprises a fixing shell, a height adjusting piece and a control piece, wherein the fixing shell is arranged on the periphery of a first telescopic rod and can allow the first vertical telescopic structure to vertically move up and down, the height adjusting piece is arranged in the fixing shell, and the control piece is used for controlling the height adjusting piece; the control piece comprises a motor connected with the height adjusting piece, a control assembly for controlling the motor to be started or stopped and a power supply structure for providing energy for the control assembly; and the control assembly comprises a central controller and an operation key, and the motor and the operation key are respectively connected with the central controller.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bone traction device which is convenient for angle adjustment. Background technique [0002] Traction is the use of the principle of action force and reaction force in mechanics to act on the affected limb through the pull of gravity to relieve the tension and retraction of the soft tissue at the fracture or dislocation, so as to reset the fracture or dislocation and achieve the purpose of treatment. Traction is divided into two categories: continuous skin traction and bone traction, which are mainly used for cervical spine fractures, pelvic fractures, femoral neck fractures, intertrochanteric fractures, femoral shaft fractures and unstable tibia and fibula fractures. [0003] A variety of traction devices have appeared on the market at present, mainly including traction chairs, traction frames that can be placed on the head of the bed or beside the bed, etc...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problem that the traction device in the prior art lacks stability and is prone to sideslip when it is placed on the hospital bed, and at the same time, in order to meet the requirement that the traction frame can adjust the height of the traction frame according to different patients and different limbs in clinical practice. To solve the problem of automatic and intelligent adjustment of angle and inclination, provide a bone traction device with convenient angle adjustment
