Abstract
The utility model relates to a aiming fixed clamp, which comprises a gill shaft screw, and a left clamp body and a right clamp which are connected through the gill shaft screw, and is characterized in that the tip of the left clamp body and the tip of the right clamp body are correspondingly provided with an aiming hole, and a clamp handle is provided with a fixing hole. The utility model also comprises a fixing device arranged on the clamp handle and an aiming device arranged on the tip of the right clamp body. The utility model can remain reduction of the fracture when in the reduction of the fracture, and is free from bone holding forceps for fixing, and is convenient when in drilling, can correctly determine the needle inlet point and the needle outlet point when the aiming device drills or nail a Kirschner wire or a screw, and is convenient and practical.
Description
Technical field
This utility model relates to a kind of aiming fixation clamps, belongs to medical instruments field.
Background technology
In bone surgery; running into the sclerite of putting than deep-seated through regular meeting need be from the opposite with Kirschner wire or screw fixings; but when playing Kirschner wire or screw from the opposite; going out pin mark tends to train off; can not go out on the pin mark ideal, and after sclerite resets, keep fixing with common bone holding forceps; bone holding forceps can hinder boring, the influence operation.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and both can keep the reduction of the fracture, the bone fixation folded block can play the aiming effect again, can be accurately the aiming fixation clamps that pin mark arrives ideal position surely that goes out of Kirschner wire or screw.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of aiming fixation clamps, comprise branchia shaft screw and the left caliper that is connected by branchia shaft screw, right caliper body, it is characterized in that: left caliper pincers point and right caliper body pincers point place correspondence have sight hole, have fixing hole on the pincers handle, also comprise fixture that is installed on the pincers handle and the sight device that is installed on the right caliper body binding clip.
Sight device comprises: sliding bar, limit rod, slip ring, connecting rod, aiming sleeve, sliding bar one end connects the branchia shaft screw other end and is connected with connecting rod, connecting rod is connected with the aiming sleeve again, the aiming sleeve is fixed on right caliper body pincers point place, corresponding with sight hole, limit rod is fixed on the binding clip place of right caliper body and the pincers handle place of left caliper, is connected with sliding bar by slip ring.
Fixture comprises fixed bar and nut, and the fixing hole that fixed bar passes on the pincers handle is threaded with nut, and wherein the fixing hole on the left caliper pincers handle penetrates handle, and the fixing hole degree of depth on the right caliper body pincers handle is less than pincers handle thickness.
Connecting rod is divided into three sections and is connected with right-handed thread by left hand thread, and connecting rod can elongate or shorten by left hand thread and right-handed thread according to aiming pincers operating position.
The sight device of aiming pincers is a sliding bar, connecting rod is connected with the aiming sleeve, thereby make sliding bar, connecting rod, the binding clip of aiming sleeve and right caliper body constitutes a parallelogram, caliper is when clamping, because the effect of limit rod, the folding of aiming pincers always keeps sliding bar parallel with the line of two pincers points, by regulating left hand thread on the connecting rod and right-handed thread are regulated connecting rod according to practical situation length, make the aiming sleeve parallel with sliding bar, promptly aim at sleeve with about the sight hole at two pincers points places corresponding, bone fixation folded block at first in use, sclerite is resetted, then left caliper pincers point place is placed on out on the ideal position of pin mark, corresponding with sight hole, right caliper body pincers points place is placed on the ideal position of entry point corresponding with sight hole and aiming sleeve, clamps caliper then, tightens the hold-doun nut on the fixed bar, finish boring or beat Kirschner wire by the aiming sleeve, like this entry point with go out pin mark all on ideal position.
The beneficial effect that this utility model had is: can keep the reduction of the fracture when the reduction of the fracture, do not need other bone holding forceps to fix, easy to operate when boring, and by sight device in boring or can accurately determine ideal entry point when playing Kirschner wire or screw and go out pin mark, convenient and practical.
