Abstract

The invention discloses an adjustable fracture repository that comprises a first guide rod, a second guide rod and a first semi-ring fixing plate; one side of the first guide rod is movably connectedwith a first semi-ring fixing plate; one side of the first semi-ring fixing plate is movably connected with a second guide rod; the top of the first guide rod is connected with a first semi-annular needle base in a penetrating mode. One side of the bottom of the first guide rod is movably connected with a second semi-ring fixing plate; the top of the second semi-ring fixing plate is fixedly connected with a second semi-ring needle seat; a needle seat sliding groove is formed in the second semi-ring needle seat; a user can rotate the rotary screw cap to loosen the connection between the needleholder and the needle seat sliding groove, the needle holder is manually moved to a fixed position, so that the needle holder moves in the needle seat sliding groove, and the insertion position of theneedle piece is conveniently adjusted; the connecting plate is vertically arranged in the middle of the semi-arc plate, so that a user can conveniently adjust the angle of the needle holder in sequence according to the position of the connecting plate, and the invention is suitable for bone fracture reduction and has a wide development prospect in the future.

Description

technical field [0001] The invention belongs to the field of orthopedic medical technology, in particular to an adjustable fracture reducer. Background technique [0002] At present, the clinical reduction of long tubular fractures is mainly through reduction and fixation after traction, and internal fixation in a stable state. The previous fracture reducer is mainly used for shortening and angular deformity. After reduction, it is difficult to stabilize and fix, and even affect internal fixation. The operation space in the entry process. [0003] Traditional fracture reduction techniques are generally closed reduction of the fracture site, and various techniques such as pulling and stretching, rotating flexion and extension lights are used, and most of them are controlled manually. The disadvantages such as difficulty in making fine adjustments make it impossible for the fracture segment to achieve anatomical reduction, what’s more, even the basic functional reduction cann...
