Medical leg fracture reduction machine

Abstract

Three Foma wheels are installed on the lower side of a rack, a rotating cylinder and the rack form a rotating pair, a lifting column and the rotating cylinder form a moving pair, a first sliding table is rotationally connected with a U-shaped frame at the top end of the lifting column, an electric cylinder can drive a longitudinal guide frame to rotate in a pitching mode, and a supporting plate is rotationally installed at the upper end of the U-shaped frame. The sliding frame is installed on a sliding block of the first sliding table and can move back and forth and be positioned, the telescopic rod and the rotating shaft form a spline transmission structure, the foot stool is used for fixing the feet of a patient and is fixedly connected with the telescopic rod, the ring type pressure sensor can monitor the axial thrust of the foot stool in real time, and the direct drive motor can drive a longitudinal shaft of the foot stool to rotate. The arc-shaped frame is fixedly connected with the U-shaped frame, the arc-shaped sliding table can rotate around the center of the arc-shaped frame, the emitter and the receiver are installed at the two ends of the arc-shaped sliding table respectively and can collect X-ray images of an affected part, and the control system is used for controlling electrified operation of the leg fracture reduction machine, establishing personal archives of a patient, formulating a reduction scheme and recording reduction data.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical leg fracture reduction machine. Background technique [0002] Tibial and fibular shaft fractures are the most common fracture types in clinic, accounting for 24% of adult body fractures. All types of fractures except crack fractures require surgical treatment. The traditional surgical method is to use open reduction and internal fixation to treat the fracture site. In most cases, steel plates are used as internal fixators to integrate the bones when they heal. However, after surgery, the incision is prone to infection due to the exposure of the incision, the destruction of the biological environment of the fracture end, and the decline in the ability of soft tissue to resist infection. , internal fixation exposure, delayed fracture healing, poor reduction and other phenomena, so in the process of clinical surgery, the focus of surgery is to improve the fracture ...

AI Technical Summary

Problems solved by technology

[0003] Due to the stretching of the surrounding muscles after fracture, the fracture end is likely to lead to shortening of the backbone and angular displacement. It is often difficult to achieve satisfactory results in manual reduction during operation, especially for patients with trauma for more than one week. length, the reduction state still cannot be maintained; how to use the indirect reduction technique to achieve a satisfactory fracture reduction effect and maintain the reduction state, and facilitate the minimally invasive implantation of the intramedullary nail has always been a difficult point in the closed reduction intramedullary nail fixation technology; Under technical conditions, traction beds are often used clinically to stretch broken bones, and the assistants who operate the traction beds need to be constantly adjusted according to the instructions of the chief surgeon. In addition, the existing traction beds are mostly manually adjusted, without quantitative standards, which is not conducive to the standardization and standardization of operations, and is expensive, which is not conducive to popularization in small and medium hospitals. Therefore, the leg fracture reduction proposed by the present invention machine has obvious meaning
