Description

Operating forceps

Technical field

The utility model is related to medical operation device field, more particularly to a kind of operating forceps.

Background technology

Operating forceps is a kind of medicine equipment commonly used in thoracic surgery.As patient while there is many places fracture of rib, and When fracture is extensive, an operative incision can not fully appear fracture site, generally using extension operative incision, or weigh again The method of new otch of performing an operation.It is larger that the former causes operation to cut, and latter increases the quantity of operative incision, both to patient with Carry out larger pain.

Utility model content

The technical problems to be solved in the utility model is that there is provided a kind of hand in order to overcome the drawbacks described above of prior art presence Art is clamped.

The utility model is to solve above-mentioned technical problem by following technical proposals：

A kind of operating forceps, it includes two clamp handles, and its feature is that clamp handle passes through hinge described in two；The bearing pin It is arranged in the leading section of the clamp handle；The leading section of clamp handle described in two is respectively provided with a tong arm, the symmetrical center line of two tong arms with Angle between the symmetrical center line of two clamp handles is 135 °~225 °；The tong arm is generally aligned in the same plane with the clamp handle；Two institutes The front end for stating tong arm is respectively provided with a clamping part, between the plane described in the plane and two where clamping part described in two where tong arm Angle be 135 °~225 °；The clamping part is arc, and the intrados of clamping part described in two is oppositely arranged；Clamp handle described in two Rearward end is respectively provided with a finger ring portion；Be respectively provided with a fastening end described in two in clamp handle, the fastening end be located at the bearing pin and Between the finger ring portion, fastening end described in two is respectively provided with toothed region, and fastening end is engaged by the engagement of toothed region described in two；Institute Clamping part, the tong arm, the clamp handle and the finger ring portion is stated to be formed in one.

It is preferred that the angle between the symmetrical center line of the symmetrical center line of two tong arms and two clamp handles is 135 ° or 225 °.

It is preferred that the finger ring portion is circular or ellipse.

It is preferred that the clamping part, the tong arm, the clamp handle and the material in the finger ring portion are stainless steel.

Positive effect of the present utility model is：Operating forceps of the present utility model has tong arm and clamping part, and pincers There is certain angle, so, doctor can be in fracture of rib internal fixation operation, by operating forceps to remote between arm and clamp handle From operative incision position rib pulled, resetted, it is fixed, need not both increase the length of operative incision, without increase hand The quantity of art otch, reduces the operation pain of patient, reaches minimally invasive purpose.

Embodiment

Name preferred embodiment, and become apparent from intactly illustrating the utility model with reference to accompanying drawing.

As depicted in figs. 1 and 2, a kind of operating forceps, it includes two clamp handles 10, and two clamp handles 10 are hinged by bearing pin 11；Pin Axle 11 is arranged in the leading section of clamp handle 10；

The front end of two clamp handles 10 is respectively provided with a tong arm 20.The symmetrical center line of two tong arms 20 and two clamp handles 10 it is symmetrical in Angle α between heart line is 135 °~225 °；It is preferred that α is 135 ° or 225 °.Tong arm 20 is generally aligned in the same plane with clamp handle 10.

The front end of two tong arms 20 is respectively provided with a clamping part 30, the plane where two clamping part 30 and the place of two tong arm 20 Angle β between plane is 135 °~225 °, it is preferred that β is 135 ° or 225 °；Clamping part 30 is arc, two clamping parts 30 Intrados is oppositely arranged.Clamping part curves inwardly, when two clamping parts are closed, and forms the shape of semicircular, as shown in Figure 3.Two Clamping part is used to clamp thoracic cavity rib.

The rear end of two clamp handles 10 is respectively provided with a finger ring portion 40；Finger ring portion 40 is circular or ellipse.

A fastening end 50 is respectively provided with two clamp handles 10, fastening end 50 is located between bearing pin 11 and finger ring portion 40, two engagings End 50 is respectively provided with toothed region 51, and two fastening ends 50 are engaged by the engagement of toothed region.

Clamp handle and the overall length of tong arm are 18~20cm.Laborsaving during for operation, the length of clamp handle is typically larger than the length of tong arm.

Clamping part 30, tong arm 20, clamp handle 10 and finger ring portion 40 are formed in one.Clamping part 30, tong arm 20, clamp handle 10 and refer to The material of ring portion 40 is stainless steel.

When there is thoracic cavity multiple location fracture of rib simultaneously in patient, and fracture scope it is more wide in range when, doctor can only pass through Expand operative incision length, or increase operative incision quantity to complete Fracture internal fixaiion operation.Due to hand of the present utility model Art tonger, which has, has certain angle between tong arm and clamping part, and tong arm and clamp handle, therefore, doctor can be in fracture of rib In fixed operation, the rib away from operative incision position is pulled by operating forceps, resetted, is fixed, need not both increase hand The length of art otch, without the quantity of increase operative incision, reduces the operation pain of patient, reaches minimally invasive purpose.

Operating forceps of the present utility model also has the advantages that easy to operate.

Although the foregoing describing embodiment of the present utility model, it will be appreciated by those of skill in the art that This is merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art On the premise of without departing substantially from principle of the present utility model and essence, various changes or modifications can be made to these embodiments, But these changes and modification each fall within protection domain of the present utility model.
