Problems solved by technology

[0003] However, after pulling the fracture side part of the patient, it is necessary to maintain the pulling position for a long time, so it is an operation that puts a large physical burden on the surgeon, and many surgeons are invested in the operation that requires only physical labor. The situation can be regarded as a form of inefficient human operation
[0004] In addition, in order to perform the above-mentioned stretching, an operating table dedicated to fracture surgery (Fracture table) is sold, but it is a form of stretching by fixing the foot, so it is difficult to accurately adjust the position of bone fragments, and it is not possible to Measures the force required to stretch the bone fragment and therefore be the cause of overstretch
[0005] Also, attempts have been made to solve the above-mentioned problems by using a surgical navigation device and a robot, but in this case, the pulling force on the robot is too large, so in order to satisfy the above-mentioned pulling force, it is necessary to increase the volume of the robot
Therefore, there is a problem that the robot cannot meet the compact design required in the operating room

Abstract

A bone retraction device and a fracture reduction system including the same are disclosed. The disclosed bone retraction device comprises: a base; a support vertically disposed on the base; a retraction shaft provided at the support in the perpendicular direction and driven in the forward and backward directions; and a double-joint part connected to the retraction shaft so as to be bent in multiple stages with respect to the driving direction of the retraction shaft.

Description

technical field [0001] The present invention relates to a bone distraction device and a fracture reduction system including the same, in particular to a bone distraction device used for joining individual bone fragments of a patient's fracture and a fracture reduction system including the same. Background technique [0002] The surgical treatment steps for arm, leg, and pelvic fractures mainly consist of reduction and fixation of bone fragments. Usually, 2 to 3 surgeons are employed in this type of operation, and the reason why so many medical staff are required is that in order to reset the fracture, it is necessary to pull the patient's arms, legs, and The pelvic region (hereinafter referred to as the fracture side region). [0003] However, after pulling the fracture side part of the patient, it is necessary to maintain the pulling position for a long time, so it is an operation that puts a large physical burden on the surgeon, and many surgeons are invested in the opera...
