Embodiment Construction

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] The overall structure of the present invention is as Figure 1 to Figure 9 shown.

[0024] A detachable long bone reset robot, consisting of a fixation mechanism and a reset mechanism, the two can be connected or disassembled, when connected, the fixation mechanism is placed above the reset mechanism, and the top of the reset mechanism is located in the U-shaped groove of the fixation mechanism , both sides are in contact with the baffles of the fixing mechanism. Use ordinary bolts to screw into the threaded holes on the side of the fixing mechanism to make the two tightly connected. When dismantling, turn the ordinary bolt in the opposite direction to separate the fixing mechanism from the reset mechanism. The fixing units of the fixing mechanism can be connected or disassembled. When connecting, the two connecting plates 1 are resp...

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...
