Problems solved by technology

For the reset device, the current rigid structure cannot take into account the large reset force and operational flexibility at the same time
If the doctor resets by hand, it will consume a lot of physical strength of the doctor, and due to the human physiological limit, this reset method has problems such as lack of stability

Embodiment Construction

[0023] The present invention is described below based on examples, but the present invention is not limited to these examples.

[0024] Such as Figure 1-3 As shown, a fracture reduction device is used for reduction in fracture surgery, including a base assembly 1, a traction device 2, a fixing device 3, and a holding needle 4. The traction device 2 is connected to the base assembly 1, and the holding needle 4 Fixedly installed on the fixing device 3 , the device also includes an elastic device 5 , one end of the elastic device 5 is connected with the straight traction device 2 , and the other end is connected with the fixing device 3 .

[0025] The elastic device 5 can achieve one-dimensional stretching, which is convenient for pulling and rotating the two parts of the fracture on the same axis, and facilitates subsequent work such as holding and fixing, and because the elastic device 5 is elastic, it can be bent, Deformation and recovery. Therefore, while the elastic device...

Abstract

The invention discloses a bone fracture reduction device. The bone fracture reduction device comprises a traction device, an elastic device and a fixing device, wherein one end of the elastic device is connected with the traction device, the other end of the elastic device is connected with the fixing device, and a control needle is fixedly installed on the fixing device. According to the bone fracture reduction device, tension provided by the elastic device is used for balancing resistance of muscles and ligaments for reset operations, so that the force needed in the reset operation is lowered, and meanwhile the enough operation flexibility is ensured.

Description

technical field [0001] The invention relates to a medical operation surgical instrument, in particular to a fracture reduction device. Background technique [0002] Fractures are relatively common and frequently occurring clinically, and are a high-energy injury disease with a high incidence rate. Especially with the rapid economic development and the acceleration of urbanization, the incidence rate of this disease shows an increasing trend year by year. [0003] Fracture reduction requires continuous force and continuous pulling, rotation and other actions to achieve reduction. During this process, it is necessary to resist the resistance caused by muscle tissue to the reduction operation. Therefore, it is necessary to provide a large reduction force during the reduction operation (especially for old patients). Fractures), also need to have excellent operational flexibility, and at the same time, avoid excessive force and cause new fractures. [0004] The existing fracture...
