Description

A kind of needle forceps with buffer

Technical field

This utility model is related to technical field of medical instruments, more particularly, to a kind of needle forceps with buffer.

Background technology

Needle forceps are a kind of conventional operating theater instruments, and needle forceps (needle holder) needle forceps are also needle holder, mainly Suture various tissues for clamping suture needle, be sometimes also used for instrumental tie, clamped in suture needle with the point of needle holder, rear 1/3 friendship It is advisable at boundary, the needle point in most cases clamping should to the left, and special circumstances can to the right, and suture answers overlapping 1/3, and will be around line overlap Part is also put in pin mouth.It is beneficial to operation, if pin is clipped in the middle of needle holder, easily pin fractures, because pin is rigidity Object, it is generally desirable that can clamp completely, is often Overexertion during use, moreover the structure of whole pair of pliers is also rigid, Excessive power must have a weak link release.Because pull bar is more elongated, become the weak link of this pliers, institute It is easy to extend because of fatigue with pull bar, lead to handle clamping position change to bring using inconvenience, or even fatigue can not be pressed from both sides Tight pin and scrap.

Utility model content

The purpose of this utility model is to solve shortcoming present in prior art, and propose a kind of with buffer Needle forceps.

To achieve these goals, this utility model adopts the technical scheme that

A kind of needle forceps with buffer, including main body, buffer and connecting rod, are provided with left finger below described main body Below ring, and left finger ring, auxiliary handle is installed, right finger ring is installed on the right side of described main body, on the left of described main body, finger is installed Groove, is provided with buffer on the right side of described main body, and described buffer is connected with connecting rod by protective case, pacifies on the right side of described connecting rod Equipped with lower pliers head, and above lower pliers head, upper grip head is installed, inside described buffer, separator tube is installed, and buffer tube interior peace Equipped with spring, inside described connecting rod, connection ring is installed.

Preferably, described left finger ring surface is screw thread anti-skid structure.

Preferably, described buffer surface is provided with regulation screw thread.

Preferably, on the right side of described separator tube, buffer layer is installed.

Preferably, described upper grip head is connected with main body by gangbar.

In this utility model, by being provided with the left of main body, finger groove is installed, finger can be put in finger groove, make Must using this needle forceps take more sane, using more laborsaving convenience, by being provided with buffer, be provided with slow inside buffer Washing pipe, and buffer tube interior is provided with spring, when can slow down engagement, the impulse force to upper grip head and lower pliers head engagement for the gangbar, prevents Only collision between upper grip head and lower pliers head, damage, and so that upper grip head and lower pliers head engagement more compact, it is tighter to hold pin, More laborsaving, by left finger ring surface for screw thread anti-skid structure so that being preferably affectedly bashful, it is difficult to slide, more convenient operation.

In figure: 1 auxiliary handle, 2 left finger rings, 3 finger groove, 4 right finger rings, 5 main bodys, 6 buffers, 7 adjust screw threads, 8 protective cases, 9 connecting rods, 10 upper grip heaies, 11 lower pliers heads, 12 separator tubes, 13 springs, 14 buffer layers, 15 connection rings, 16 gangbar.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.

Reference picture 1-3, a kind of needle forceps with buffer, including main body 5, buffer 6 and connecting rod 9, main body 5 lower section peace Equipped with left finger ring 2, and auxiliary handle 1 is installed below left finger ring 2, right finger ring 4 is installed on the right side of main body 5, is provided with the left of main body 5 Finger groove 3, is provided with buffer 6 on the right side of main body 5, buffer 6 is connected with connecting rod 9 by protective case 8, connecting rod 9 right side peace Equipped with lower pliers head 11, and upper grip head 10 is installed above lower pliers head 11, separator tube 12 is installed inside buffer 6, and separator tube Spring 13 is installed inside 12, connection ring 15 is installed inside connecting rod 9, left finger ring 2 surface is screw thread anti-skid structure, buffer 6 surfaces are provided with regulation screw thread 7, are provided with buffer layer 14 on the right side of separator tube 12, and upper grip head 10 passes through gangbar 16 with main body 5 even Connect.

Operation principle: when using a kind of needle forceps with buffer, first pass through finger and pass through left finger ring 2 and right finger ring 4, using palm when held main body 5, by exerting oneself between finger, so that the engagement between left finger ring 2 and right finger ring 4, from And the gangbar 16 within connecting rod 9 drives and engages between upper grip head 10 and lower pliers head 11, operation needle is clamped, starts to operate, Simultaneously when upper grip head 10 and lower pliers head 11 engage, the separator tube 12 within buffer 6 can buffer the power of gangbar 16, Ensure that the stability of engagement, the engagement collision between protection upper grip head 10 and lower pliers head 11, improves steady to operation needle clamping Qualitative.

The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not Be confined to this, any those familiar with the art in the technical scope that this utility model discloses, according to this practicality New technical scheme and its utility model design in addition equivalent or change, all should cover in protection model of the present utility model Within enclosing.
