Abstract

A kind of pelvic fracture reset guiding fixing forceps of better reduction; Comprise: the left and right pincers point that left and right clamp handle is fixedly connected with the clamp handle upper end; Right pincers point is column; Left pincers point is tubbiness, is designed with guide channel in the left pincers point; The utility model has the advantages that: owing to be designed with guide channel in the left pincers point in the utility model, so can be at pincers sharp residing reduction point place squeeze into Kirschner wire or screw to fracture fixation by guide channel.

Description

Fracture of pelvis reset guide fixation clamps

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of fracture of pelvis reset guide fixation clamps.

Background technology

At present, treat clinically fracture of acetabulum, the quality that resets is the key for the treatment of, and whether the reduction of the fracture is satisfied with, and will for its hip joint activity from now on and the generation of heavy burden and osteoarthritis secondary, bring significant impact.Fracture of acetabulum is in case take place, particularly comminuted fracture and the obviously fracture of displacement, because its anatomical features and fracture line trend are comparatively complicated, need resets or pre-fixes by reduction forceps more in operation; The point-like reduction forceps has the reset response of consistent approval in the present operating theater instruments; This reduction forceps comprises: hard-wired pincers point on left and right clamp handle and the clamp handle; Left and right clamp handle is rotatably connected relatively; The pincers point of reduction forceps is stuck on the surface of bone at fracture two ends during use, makes the reduction of the fracture and pre-fix, and then stamp Kirschner wire at fracture and make the reduction of the fracture and fixing; Doing the reduction of fracture with this apparatus can't block at the pincers point of reduction forceps on the reduction point of bone and directly be fixed or pre-fix, this point often is exactly the fixing optimal entry point of the reduction of the fracture or extends point, therefore use common reduction forceps usually to cause the fixing point skew, thereby the partial loss that causes resetting, reset effect are poor.

Summary of the invention

The purpose of this utility model provides a kind of fracture of pelvis reset guide fixation clamps of better reduction.

For achieving the above object, the technical solution adopted in the utility model is: a kind of pelvic fracture reset guiding fixing forceps, comprising: the left and right pincers point that clamp handle is fixedly connected with the clamp handle upper end; Its characteristics are: right pincers point is designed with guide channel for column in the left pincers point.

The utility model has the advantages that: owing to be designed with guide channel in the left pincers point in the utility model, so can be at pincers sharp residing reduction point place squeeze into Kirschner wire or screw to fracture fixation by guide channel, this optimal reset point fixedly fracture can avoid the partial loss that resets, guaranteed the reset effect of operation.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is further described:

A kind of pelvic fracture reset guiding fixing forceps, as shown in Figure 1, comprising: the left and right pincers point that clamp handle 5 is fixedly connected with clamp handle 5 upper ends; Right pincers point 4 is column, is designed with guide channel 1 in the left pincers point 2; In the present embodiment, enclose spine 3 structures with one respectively on the outer rim of the relative inner face of two pincers points about; This kind structure can make pincers point of the present utility model increase with the grasping force of fracturing on the fixing point that resets of fracture, has kept rivet clasp power of the present utility model and hold, thereby has kept the good fixation that resets of the utility model.

During use, with the sharp both sides that are stuck in fracture end of pincers of the present utility model, with the reduction of the fracture, from the guide channel that clamps point, Kirschner wire or screw are squeezed in the fracture then, with fracture fixation.

The beneficial effects of the utility model are: because pincers point of the present utility model is designed with guide channel, institute With 1, the utility model possesses orientating function, vital tissue around the fixture skew damage can not occur, Make the fixing safety, reliable that resets; 2, can directly squeeze into fixture at reduction point and fix or pre-fix, make Operation technique is easier and damage little; 3, be fixed at the best fixing point of the reduction of the fracture, avoided Reset partial loss and reset has dissatisfiedly guaranteed the reset effect of operation.

Claims

1, a kind of pelvic fracture reset guiding fixing forceps, comprising: the left and right pincers point that left and right clamp handle (5) is fixedly connected with clamp handle (5) upper end; It is characterized in that right pincers points (4) are column; Left pincers points (2) are tubbiness, are designed with guide channel (1) in the left pincers point (2).

2, fracture of pelvis reset guide fixation clamps according to claim 1 is characterized in that: have circle spine (a 3) structure on the outer rim of the opposed inside face of described left and right two pincers points respectively.
