Abstract

The invention discloses a detachable long bone reduction robot. The detachable long bone reduction robot comprises a fixing mechanism and a reduction mechanism which are connected with or separated from each other, wherein the fixing mechanism comprises two groups of same fixing units which are connected with or separated from each other via two same connecting plates (1); the reduction mechanism is provided with a small annular platform (11), a large annular platform (12), twelve universal hinges (13) and six driving rods (14); the small annular platform (11) is connected with a bottom plate (2) and the universal hinges (13); the universal hinges (13) are connected with the driving rods (14); the universal hinges (13) are connected with the large annular platform (12); the large annular platform (12) is connected with the bottom plate (2). Due to the adoption of a parallel mechanism of six degrees of freedom, the detachable long bone reduction robot has the advantages of high accuracy, high loading capacity, high rigidity, compact structure and the like; the detachable long bone reduction robot is applied to long bone fracture reduction, is used for replacing doctor operation, and contributes to increasing the reduction accuracy, reducing operation wounds and lowering the probability of operative infection.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a detachable long bone reduction robot. Background technique

[0002] The traditional reduction method for long bone fractures is open reduction under direct vision, and the doctor relies on the experience and skills of the doctor. This treatment method artificially turns closed fractures into open fractures, which increases the chance of infection. In the middle, it is easy to destroy the blood supply, cause the necrotic area of ​​the fracture end to increase, and cause delayed union and nonunion. This reset method also has problems such as long operation time, high work intensity of doctors, and poor reset easily. Although the intramedullary nailing and minimally invasive plate fixation technologies developed in recent years have solved the problems caused by open surgery, the X-ray radiation needs to be continuously performed during the operation, and the amount of ra...
