Abstract

The utility model discloses a multifunctional bone nipper with integration of bending and shearing. The bone nipper comprises a nipper head (6), a nipper gill (7) and a nipper handle (8), wherein the nipper head (6) is formed by hinging a left nipper body (4) and a right nipper body (5). The multifunctional bone nipper is characterized by also comprising a folding-cutting device that is arranged on the nipper head (6) and formed by a needle pressing handle (1), a cutting needle sheet (2) and at least one needle clamping hole, wherein the needle pressing handle (1) is hinged beside the side surface of the jaw of the nipper head (6); the cutting needle sheet (2) is arranged on the side surface of the needle pressing handle (1), opposite to the nipper head (6); and each needle clamping hole consists of semicircular grooves (3) arranged oppositely on an upper jaw and a lower jaw inside the jaw of the nipper head (6). The multifunctional bone nipper can combine a bending bone needle and a shearing needle at one time and has the characteristics of saving labor and being convenient and the like, thus being suitable to clinical use.

Description

A kind of multi-functional bone forceps of curved scissors one

Technical field

This utility model relates to a kind of surgical instruments that is used for synthetism, relates in particular to a kind of bone forceps.

Background technology

The spicule internal fixation is common bone surgery method, concrete grammar is: the doctor at first imbeds the suitable degree of depth (squeezing into grey matter) according to patient's practical situation clip spicule, for preventing that needle body is absorbed in the body, the general gram formula bone forceps that uses bends to certain angle with its exposed parts, the reuse vice cuts off redundance (staying about 5mm), at last, imbed skin and do wrapping.Exist following problem in the said method: though the head of a gram formula bone forceps is less than normal, be beneficial to clamping gram formula pin, but carry out the limited and needle body of angle that the spicule bending bent with it and can't keep straight easy camber, torsion conducted to sclerotin on every side when spicule was crooked, often cause that sclerotin splitting or spicule are loosening, thereby influence surgical effect; Two, the reuse vice is sheared spicule after crooked spicule, makes crooked good spicule distortion easily, and makes the patient produce pain.

The patent No. is to disclose a kind of osseous pin folding forceps in 8721231.5 the Chinese utility model patent, it is that the following spicule of 2.5mm is crooked and keep needle body straight simultaneously that this osseous pin folding forceps can make diameter, and this osseous pin folding forceps has characteristics such as laborsaving, that bending effect is good.But this osseous pin folding forceps need be sheared spicule at reuse vice after the crooked spicule, makes crooked good spicule distortion easily.

Summary of the invention

The bone forceps that technical problem to be solved in the utility model is to provide a kind of bending simultaneously and shears spicule.

This utility model is achieved in that

A kind of multi-functional bone forceps of curved scissors one, this bone forceps comprises by left caliper and the hinged binding clip that constitutes of right caliper body, the pincers gill and pincers handle, it is characterized in that also comprising the folding cutting apparatus that is located on the binding clip, this folding cutting apparatus by the pressing handle, cut faller gill and at least one and press from both sides pin hole and form, wherein

Lateral one side of tiger that described pressing handle is articulated in binding clip;

The described faller gill of cutting is located on the side with respect to binding clip of pressing handle;

Described each folder pin hole all is made up of the upper jaw in the tiger that is located at binding clip relatively and epimandibular half slot.

Because the diameter of the spicule that uses in the different bone surgeries is scarcely equal, for the spicule folder of different-diameter is steady, this utility model in the tiger of binding clip the upper jaw and lower jaw on the half slot that three groups of diameters do not wait is set respectively, when the upper jaw in the tiger of binding clip and lower jaw close when closing, form three folder pin holes that diameter does not wait.

Because spicule is generally harder, to cut faller gill and must enough sharply it could be cut off, this makes that the cutting edge of cutting faller gill is generally thinner, after spicule cuts off, cuts faller gill and directly acts on to clamp on the gill and make the cutting edge of cutting faller gill impaired easily.This utility model is provided with a joint-cutting with the cutting edge opposite position of cutting faller gill on the described pincers gill; during shearing; a clip is pressed close to form with the both sides of cutting faller gill respectively in the two side of this joint-cutting; respectively from the double side acting of spicule body in spicule; help spicule is cut off, and after the spicule cut-out, cut faller gill and be absorbed in the joint-cutting; can protect the cutting edge of cutting faller gill effectively, prolong its service life.

For adapting to the requirement of medical equipment, making material of the present utility model is preferably rustless steel, and the hardness of cutting faller gill should be greater than 380 dimension formulas.

This utility model compared with prior art has the following advantages:

1, easy to use, save time.This utility model bending simultaneously and shearing spicule need not to re-use vice and shear spicule behind crooked spicule, saved operating time greatly.

2, laborsaving.This utility model mainly active force by the pressing handle is crooked and cut-out with spicule, and according to lever principle as can be known, pressing handle length is long more, uses laborsaving more.

3, shearing point is accurate.In this utility model, cut faller gill, can exactly spicule be cut off the length in reserve that obtains planning as long as the cut-out point that will pre-determine is aimed at.

4, it is straight to remain needle body.This utility model can keep the straight of needle body when crooked and shearing spicule, solved the problem that when shearing crooked good spicule is out of shape once more.

Function of the present utility model is achieved in that

As shown in Figure 4, at first spicule 11 is put into the folder pin hole that is formed by half slot 3, the pincers handle 8 of holding with a firm grip is with clamping spicule 11, and the cut-out points that make spicule 11 be scheduled to are on the cutting edge limit of cutting faller gill 2;

As shown in Figure 5, with pressing handle 1 to depress, make spicule 11 bendings to the direction of binding clip 6;

As shown in Figure 6, continuation will press handle 1 to depress, and under the interaction of cutting faller gill 2 and joint-cutting 9, spicule 11 be cut off.
