Embodiment Construction

[0022] The present invention is described below based on examples, but the present invention is not limited to these examples.

[0023] Such as figure 1 As shown in -6, a fracture reduction forceps with positioning and guiding functions is used for the reduction in patella fracture surgery, the guidance of Kirschner wire fixation and the guidance of the drill bit for drilling internal fixation holes, including the handle and the head of the forceps. The pliers handle is connected with the pliers head, the pliers handle includes a first pliers handle 1 and a second pliers handle 2, and the first pliers handle 1 and the second pliers handle 2 are connected. The pliers include a first pliers 3 and a second pliers 4, and the first pliers 3 and the second pliers 4 are opposite to each other to realize the clamping function.

[0024] Such as figure 2 As shown, a guide device is provided on the pliers head, that is, a first guide device 5 is provided at one end of the first pliers...

Abstract

The invention discloses reduction forceps for bone fracture with positioning and guiding functions. The reduction forceps are composed of forceps handles and forceps heads, the forceps handles are connected with the forceps heads which comprise the first forceps head and the second forceps head, the first forceps head and the second forceps head are provided with a first guide device and a secondguide device respectively, a first guide hole and a second guide hole are formed in the first guide device and the second guide device respectively, and the central line of the first guide hole is coincident with that of the second guide hole. In the reduction forceps, a Kirschner wire or a drill bit can be very conveniently inserted through the guide holes so as conduct internal fixing hole drilling. The reduction forceps are used in an internal fixation operation of patella fracture, and early-stage clamping and fixing of patella fracture reduction and through hole positioning and guiding can be achieved.

Description

technical field [0001] The invention relates to a medical operation surgical instrument, in particular to a fracture reduction forceps with a positioning and guiding function. Background technique [0002] Patella fractures are often caused by violent contraction of the quadriceps femoris or direct impact. Generally, except for non-displaced patellar fractures that can be treated non-operatively, most patellar fractures require surgical treatment. The size of the fracture fragments is similar, and open reduction and internal fixation are feasible. However, the reduction forceps used in the process of fracture reduction will often affect the position of the Kirschner wire or cause problems such as poor position of the Kirschner wire. Repeated Kirschner wire fixation may occur during the operation, which not only causes fractures The iatrogenic injury prolongs the operation time and brings certain complications to the clinical treatment. Contents of the invention [0003] ...
