Skeletal traction acting force device

Abstract

The invention relates to a skeletal traction acting force device. The skeletal traction acting force device comprises a traction component, an elastic part, a force sensor, an adjusting component used for adjusting the stretching length of the elastic part, a traction signal receiving and transmitting module, a control module and a power supply, wherein the elastic part or the force sensor is connected with the traction component. The control module outputs a control signal according to the comparison result of a traction force actual value feedback signal and a traction force set value input signal received by the traction signal receiving and transmitting module so as to control the adjusting component to adjust the stretching length of the elastic part, and then the force sensor detects that the actual value of traction force borne by the elastic part with the length changed is equal to a set value; meanwhile, the control module outputs a control signal according to an input signal so as to control the adjusting component to keep the acting time period of the elastic part. According to the skeletal traction acting force device, the single or combined skeletal traction acting force and acting time period can be set as needed; besides, continuous adjustment of the skeletal traction acting force can be achieved, the adjustment precision is high, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to a medical auxiliary instrument, in particular to a bone traction force device. Background technique [0002] The current bone traction surgery generally uses a bone traction device to slowly reset the fracture or dislocation by fixing it at a specific position. It is not only a method of reduction, but also can play a good role in fixation. It is often used in patients with skin injury, severe swelling, wound infection or severe bone comminuted who are not suitable for internal fixation. [0003] Current bone distraction devices such as figure 1 As shown, it mainly includes the bone needle 101 inserted on the traction part 106, and the bone needle 101 is connected to traction bow 102, rope 103, traction frame 104 (such as a pulley) and traction weight 105 and other appliances in turn, mainly by changing the traction weight The weight of code 105 is used to increase or decrease the size of the bone traction force, so as to rea...
