Description

Surgical forceps

Technical Field

The utility model relates to a binding clip field especially relates to an operation pincers.

Background

The operation is a main treatment method of surgery, and is a treatment for a doctor to perform resection, suture, etc. on a patient body with a medical instrument. Aims to cure or diagnose diseases, such as removing pathological tissues, repairing injuries, transplanting organs, improving the functions and the forms of organisms and the like.

In some resection operations, the purpose of radical treatment can be achieved only by partially resecting the tissues around the diseased tissue while resecting the diseased tissue. (for example, in breast cancer breast protection surgery, the optimal incisal edge tissue should be less than or equal to 10mm, the width of the incisal edge tissue is further enlarged, and the appearance and function of the breast after the surgery cannot be influenced but the improvement of the treatment effect cannot be brought). At present, the evidence of evidence-based medical science and the operation specification provide accurate requirements for the distance of incisal edges, but in the operation process, the size of the excision of the tissues around the pathological tissues depends on the visual judgment and personal experience of an operator, so that errors are inevitable, and the operation effect is unstable. There is no surgical instrument that can assist a surgeon in accurately resecting diseased tissue during surgery.

Detailed Description

The present invention will be described in detail and with particular reference to certain embodiments and drawings for better understanding of the invention, but the scope of the invention is not limited by the following embodiments.

As shown in fig. 1, the present invention provides a pair of surgical forceps, comprising:

the first pliers body 10 comprises a first clamping portion 11 and a first pliers handle 12, wherein the first clamping portion 11 comprises a first upper pliers head 13 and a first lower pliers head 14 which are parallel to each other, and the distance between the first upper pliers head 13 and the first lower pliers head 14 is fixed;

the second pliers body 20 is hinged with the first pliers body 10, the second pliers body 20 comprises a second clamping portion 21 and a second pliers handle 22, the second clamping portion 21 comprises a second upper pliers head 23 and a second lower pliers head 24 which are parallel to each other, and the distance between the second upper pliers head 23 and the second lower pliers head 24 is fixed;

and the distance between the first upper jaw 13 and the first lower jaw 14 is equal to the distance between the second upper jaw 23 and the second lower jaw 24.

As a preferred example, the distance between the first upper binding clip 13 and the first lower binding clip 14 is 5-100 mm. More preferably, the distance between the first upper binding head 13 and the first lower binding head 14 is 10-30 mm. The fixed distance is set according to the size of the tissues around the lesion tissues needing to be accurately cut in the operation, so that different operation requirements are met.

As a preferred example, the first caliper body 10 and the second caliper body 20 are hinged by a pin 30.

As a preferable example, the distal end portions of the first upper jaw 13, the first lower jaw 14, the second upper jaw 23 and the second lower jaw 24 each have an upward curvature; the length of the first upper binding clip 13 is less than that of the first lower binding clip 14; the length of the second upper binding clip 23 is smaller than the length of the second lower binding clip 24. The purpose of the above design is: the surgical forceps used as the extension of the hands of a doctor in an operation are usually used at a certain inclination angle, and the design ensures that the far-end connecting lines of the four forceps heads are kept parallel to the excised tissues under the natural using posture as much as possible, so that the surgical forceps are convenient to contact with the excised tissues at the same time when in use.

As a preferred example, the first and

second handles

12, 22 are provided with a locking structure (not shown in fig. 1) inside.

It is worth mentioning that: in fig. 1, the first handle 12 is integrally connected to the first lower jaw 14, and the second handle 22 is integrally connected to the second lower jaw 24, which are only one type of connection. More preferably, the first handle 12 is integrally connected to the first upper jaw 13, and the second handle 22 is integrally connected to the second upper jaw 23, so that the user is less obstructed from the view when the pliers are used.

In the utility model, the first upper binding clip 13 and the first lower binding clip 14 are fixedly connected through the first connecting piece 15; the second upper binding clip 23 and the second lower binding clip 24 are fixedly connected by a second connecting piece 25. The further explanation is that: in fig. 1, the first connecting piece 15 and the second connecting piece 25 are both located between the hinge and the forceps handle, and the above is only one connection mode. More preferably, the first connecting piece 15 and the second connecting piece 25 are both located between the hinged part and the far end of the forceps head, and the design can make the forceps head part shorter, save materials and make the forceps more portable.

With reference to fig. 2, in order to apply the surgical forceps of the present invention to the breast circumcision, the distance between the first upper forceps head 13 (the second upper forceps head 23) and the first lower forceps head 14 (the second lower forceps head 24) is set to be 10 mm:

the forceps handles of the surgical forceps are held by hands, so that the first clamping part 11 and the second clamping part 21 clamp tissues after being closed, meanwhile, the lower edges of the first upper forceps head 13 (the second upper forceps head 23) and the first lower forceps head 14 (the second lower forceps head 24) are respectively positioned at the edge A and the edge B, and then the tissues are cut along the lower edges of the first upper forceps head 13 (the second upper forceps head 23) and the first lower forceps head 14 (the second lower forceps head 24); wherein the A edge is the outer edge of the tumor, the B edge is the smallest circumferential incisal edge, and the tissue (about 10mm wide) between the A edge and the B edge is the standard surgical incisal edge tissue.

The above description is only an example of the preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and those skilled in the art should be able to realize the equivalent alternatives and obvious variations of the present invention.
