Multifunctional intra-articular fracture guide apparatus

Abstract

The invention discloses a multi-function guider for inter-articular fracture, which mainly consists of a main support arm, a guide arm and a fixed rod, wherein both the main support arm and the guidearm are arc-shaped, which can stretch along an arc direction when being sleeved and combined are temporarily fixed via a knob. The front end of the guide arm forms a fixed head pointing to the centerof a circle when being bent inwards, the fixed rod can be pulled and arranged on the main support arm radially and flexibly and is fixed via the knob. The front end of the fixed rod forms another fixed head pointing to the center of a circle. The position where the main support arm is sleeved with the guide arm is provided with a plurality of radial through guide holes. The multi-function guider can fix fractured blocks temporarily, defines the direction of a temporarily fixed kirschner wire and the direction of a screw to fix the fractured block without enlarging a notch, and a screw for fixation can be screwed in from a screw guide pin conveniently, thus the multi-function guider is very convenient and practical.

Description

technical field [0001] The present invention relates to orthopedic surgical instruments, more particularly intra-articular fracture guides. Background technique [0002] At present, when performing fracture reduction and internal fixation on intra-articular fractures with complex structures, it is often necessary to accurately determine whether the screw or other internal fixation has firmly fixed the fracture and whether the direction of fixation is reasonable, so as to meet the "minimally invasive" treatment as much as possible. Otherwise, repeated poor fixation will reduce the fixation strength of the screw to the fracture, but the existing orthopedic medical devices do not have such functions. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention aims to provide a multifunctional intra-articular fracture guide. [0004] The technical scheme adopted in the present invention is: [0005] A multi-functional intra-articular...
