Hyperextension tibial plateau fracture reduction forceps

Abstract

The invention discloses hyperextension tibial plateau fracture reduction forceps. The hyperextension tibial plateau fracture reduction forceps comprise a first forceps body, a second forceps body anda screw rod, wherein a first flat plate of a flat structure is formed at one end of the first forceps body; an arc-shaped part of an arc-shaped structure is formed at the other end of the first forceps body; the side, away from the first flat plate, of the first arc-shaped part extends in the direction away from the arc-shaped corner of the first arc-shaped part and forms an insertion tongue; a first connecting sleeve is arranged on the side, close to the first flat plate, of the arc-shaped part; a second flat plate of a flat structure is formed at one end of the second forceps body and attached to the first flat plate; an arc-shaped guide part which is of an arc-shaped structure and used for being in sliding fit with the insertion tongue of the first forceps body is formed at the other end of the second forceps body; and a second connecting sleeve coaxial with the first connecting sleeve is arranged on the side, close to the second flat plate, of the arc-shaped guide part; one end ofthe screw rod penetrates through the first connecting sleeve and is rotationally connected with the second connecting sleeve; the portion, penetrating through the first connecting sleeve, of the screwrod is a threaded part and is in threaded connection with the first connecting sleeve; and the first forceps body and the second forceps body are turned over through rotation of the screw rod. The scheme is reliable in implementation and convenient to operate.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hyperextension type tibial plateau fracture reduction forceps. Background technique [0002] Existing reduction of hyperextensive tibial plateau fractures mostly uses scissor-type reduction forceps, which perform traction and reduction on the tibial plateau through the jaws at the end. However, when this structure is expanded, it presents a The main supporting force of the open structure is provided by the locking structure at the end. This structure will have a large operation vibration problem and is easy to cause secondary damage. Contents of the invention [0003] In view of the situation of the prior art, the object of the present invention is to provide an overextension type tibial plateau fracture reduction forceps with simple structure, flexible operation, stability and reliability. [0004] In order to realize above-mentioned technical purpose, the technical scheme th...
