Problems solved by technology

[0004] However, for this refractory intertrochanteric fracture operation, the operation time is longer, and during the long-term operation process, it is difficult to maintain the stability when using items such as a hand-held top stick to cover the stubble and using a periosteum screwdriver to support the fractured limb. Stable stress will cause the bone stubble to loosen or even tilt up again; at the same time,

Abstract

The invention discloses an irreducible intertrochanteric fracture reduction holding device, and relates to the field of medical apparatus and instruments. The holding device comprises a holding clampprovided with a limit plate adjusting the opening and closing degree, a top pressure mechanism which comprises a fixed rod perpendicular to the holding clamp, a jacking mechanism which comprises a link mechanism capable of changing the height of the link mechanism by rotating an adjusting rod, wherein a bowl-shaped connecting frame provided with connecting holes is arranged on the fixed rod, and athreaded rod is inserted into the connecting frame through any connecting hole. The holding device can be mechanically fixed at the distal end, a required incision at the fracture end is very small,blood supply cannot be destroyed, the position of a top pressure rod can be adjusted freely to cooperate with the jacking mechanism capable of adjusting the support height below the limbs, and then the device adapts to the phenomenon that cocked stone stubble reaches the best compression state.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a reduction and holding device for irreversible intertrochanteric fractures. Background technique [0002] In intertrochanteric fracture surgery, it is necessary to use a traction bed for traction. Due to the effect of continuous traction, the strength of the muscles will cause the bone stubble to rise at the fracture end. During the operation, the raised stubble needs to be pressed back position to allow the operation to continue. [0003] In the conventional surgical operation of compressing the bone stubble, an incision is made at the fracture end, and the raised bone stubble is directly pressed down with a hand-held mandrel or other objects, or the raised part is clamped with holding forceps, and at the same time, the raised bone stubble is clamped manually. The support is used to support the patient's limbs from below, so as to work together to perform the operation. [0004...
