Since the needle head is an integrated structure, the operator does not need to apply a clamping action, so the operation is more convenient; since the needle head and the threading hole always pass through the needle entry hole of the other forceps head, the operator can quickly and accurately find / control the suture thread end, thereby quickly and accurately completing a stitch.

Description

Technical Field

[0001] The utility model relates to the technical field of surgical suturing tools, in particular to a posterior urethra anastomotic forceps. Background Art

[0002] There are a large number of patients with posterior urethral stenosis in urology who need treatment, and the best surgical method for treating posterior urethral stenosis is to perform stricture segment resection and end-to-end anastomosis.

[0003] However, due to the resection of the posterior urethral stricture, the proximal urethral edge retracts close to the bladder neck, and the suture position is deep and the space is narrow when operating from the perineal incision. It is difficult to anastomose with conventional suture needles and needle holders: it is difficult to sew with small needles, and the needle is easy to break when suturing the tissue around the scar, causing greater medical risks; it is difficult to insert and remove the needle with a large and thick suture needle, and the space is too small. The operation often cannot be accurately sutured, the mucosa cannot be anastomosed end to end, and the surgical effect is unstable.

[0004] The prior art, or traditional needle holders, such as Chinese patent CN219331770U published on 2023-07-14, Chinese patent CN211213305U published on 2020-08-11, and Chinese patent CN215534701U published on 2022-01-18, etc., all use a forceps mouth to clamp the needle body, and then control the needle body to puncture and perform suturing. This method requires the operator to perform two actions at the same time: clamping the needle body and controlling the puncture, which is prone to mistakes. For example, the needle body may loosen during the puncture and suturing process. In addition, after the needle completes a puncture, it is necessary to find / control the position of the needle and guide the suture thread that has come out, which often requires multiple operations to complete. Utility Model Content

[0005] The utility model aims to provide a posterior urethral anastomotic forceps, which can more conveniently operate the puncture and suturing action, and complete one-needle suturing more quickly and accurately;

[0006] The utility model provides a posterior urethra anastomosis forceps, comprising a first forceps body and a second forceps body, a suturing needle is connected to one side of the forceps head of the first forceps body that anastomoses with the second forceps body, the tip of the suturing needle has a threading hole for passing a suture thread; a needle entry hole is arranged on the forceps head of the second forceps body, when the forceps heads of the first forceps body and the second forceps body move toward each other for anastomosis, the suturing needle passes through the needle entry hole, and the threading hole passes through the needle entry hole.

[0007] Furthermore, the first clamp body and the second clamp body are hingedly connected via a hinge.

[0008] Furthermore, the hinge includes a first rotating member and a second rotating member, and the first rotating member and the second rotating member are axially overlapped and rotationally connected.

[0009] Furthermore, the handle and the pliers head of the first pliers body are respectively connected to the first rotating member, and the handle and the pliers head of the second pliers body are respectively connected to the second rotating member.

[0010] Furthermore, the handle of the first pliers body is a straight handle structure.

[0011] Furthermore, the bending angle of the connection between the handle of the first pliers body and the pliers head is greater than 90 degrees.

[0012] Furthermore, a finger ring is provided at the end of the first pliers body.

[0013] Furthermore, the handle of the second pliers body is an L-shaped structure.

[0014] Furthermore, the bending angle of the connection between the handle of the second pliers body and the pliers head is greater than 90 degrees.

[0015] Furthermore, a finger ring is provided at the end of the second pliers body.

[0016] The beneficial effect of the utility model is that by adopting a longer first clamp body and a longer second clamp body, the clamp head can be more deeply inserted into the proximal end of the posterior urethra for surgery. An inner straight suture needle is integrally arranged on the inner side of the clamp head of the first clamp body, and a threading hole is provided at the tip thereof. The inner side of the clamp head of the second clamp body has a needle entry hole. During surgery, the two clamp heads face each other and match each other, so that the suture needle directly passes through the needle entry hole after puncture, and the suture thread passes through the threading hole and passes out of the clamp head from the inside of the urethra to the outside. The suture thread head is clamped with clamps or tweezers on the outside of the urethra, and the other end in the urethral cavity is used to complete the one-needle suture of the proximal urethral mucosa inside and outside. In this process, since the needle head is an integrated structure, the surgeon does not need to apply a clamping action, so the operation is more convenient; since the needle head and the threading hole always pass through the needle entry hole of the other clamp head, the surgeon can quickly and accurately find / control the suture thread head, so as to quickly and accurately complete the one-needle suture. Thereby improving the success rate of surgery, reducing the burden of surgery, and facilitating medical care operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1

[0030] like Figure 1-Figure 2 As shown, the utility model provides a posterior urethral anastomotic forceps, comprising a first forceps body 1 and a second forceps body 2. A suture needle 3 is connected to a side of the forceps head of the first forceps body 1 that is anastomosed with the second forceps body 2. The tip of the suture needle 3 has a threading hole 301 for passing a suture thread. A needle entry hole 203 is provided on the forceps head of the second forceps body 2. When the forceps heads of the first forceps body 1 and the second forceps body 2 are in anastomosing motion toward each other, the suture needle 3 passes through the needle entry hole 203, and the threading hole 301 passes through the needle entry hole 203.

[0031] Specifically, the first clamp body 1 and the second clamp body 2 are hinged at the front (near the clamp head 102, 202), and the operator holds the rear handle (101, 201). The suture needle 3 is fixedly arranged on the inner side of the clamp head 102 of the first clamp body 1, and its needle end is a sharp point for puncturing the lead wire. The tip of the suture needle 3 is provided with a threading hole 301 for the suture thread to pass through, which is similar to the needle structure of a sewing machine.

[0032] During use, the suture thread is passed through the threading hole 301, and the operator holds the rear handle (101, 201) and controls the clamp heads (102, 202) of the first clamp body 1 and the second clamp body 2 to be located at the positions on both sides of the suture opening, and then operates the suture needle 3 to puncture the suture openings on both sides of the posterior urethra. During or after the puncture, the two clamp heads (102, 202) gradually close until the suture needle 3 passes through the needle entry hole 203, and the threading hole 301 passes through the needle entry hole 203. At this time, the suture thread is also carried out of the clamp head 202. The suture thread end is clamped by the operator with clamps or tweezers and led out from the outside of the urethra together with the inner thread end to complete a stitch. In this process, since the needle head is an integrated structure, the operator does not need to apply a clamping action, so the operation is more convenient; since the needle head and the threading hole 301 always pass through the needle entry hole 203 of the other clamp head 202, the operator can quickly and accurately find / control the suture thread end, thereby quickly and accurately completing a stitch. Thereby improving the success rate of surgery, reducing the burden of surgery, and facilitating medical operations.

[0033] Example 2

[0034] The first pliers body 1 and the second pliers body 2 are hingedly connected by a hinge 4. The hinge 4 includes a first rotating member 401 and a second rotating member 402. The first rotating member 401 and the second rotating member 402 are axially overlapped and rotatably connected. The handle and the pliers head of the first pliers body 1 are respectively connected to the first rotating member 401, and the handle and the pliers head of the second pliers body 2 are respectively connected to the second rotating member 402.

[0035] Specifically, the first pliers body 1 and the second pliers body 2 are hinged at the front (near the pliers head) by a hinge 4 to increase the handle length and save effort. The hinge 4 is two rotating blocks that overlap and rotate with each other, and can be prevented from falling off by a concave-convex structure (such as hand pliers) or a loose rivet structure (such as scissors). This structure is common in the prior art and will not be described in detail. Although the first connecting member and the second connecting member are arranged in different planes that overlap with each other, the pliers heads of the first pliers body 1 and the second pliers body 2, or the suture needle 3 and the needle insertion hole 203 are located in the same plane so that the suture needle 3 can be inserted into the needle insertion hole 203. This can be achieved by bending a certain pliers head in height, for example, by attaching Figure 2 The clamp head of the second clamp body 2 is bent upward to maintain the same height as the clamp head of the first clamp body 1.

[0036] Example 3

[0037] The handle 101 of the first pliers body 1 is a straight handle structure. The bending angle of the connection between the handle 101 of the first pliers body 1 and the pliers head 102 is greater than 90 degrees. A finger ring 5 is provided at the end of the first pliers body 1. The handle of the second pliers body 2 is an L-shaped structure. The bending angle of the connection between the handle 201 of the second pliers body 2 and the pliers head 202 is greater than 90 degrees. A finger ring 5 is provided at the end of the second pliers body 2.

[0038] Specifically, the handles (101, 201) and the clamp heads (102, 202) of the first clamp body 1 and the second clamp body 2 form a long handle elbow structure, so that the two clamp heads (102, 202) are located on the side of the handles (101, 201) during operation, so that the operator's hands can operate on the side of the visual field during operation, making it more convenient to observe the surgical area. The operator's fingers can be held in the two finger rings 5 ​​for operation.

[0039] Working mode and principle of this utility model:

[0040] An inner straight suture needle 3 is integrally arranged inside the clamp head 102 of the first clamp body 1, and a threading hole 301 is provided at its tip. A needle entry hole 203 is provided inside the clamp head 202 of the second clamp body 2. During the operation, the two clamp heads (102, 202) are aligned with each other, so that the suture needle 3 directly passes through the needle entry hole 203 after puncture, and the suture thread passes through the threading hole 301 and passes out of the clamp head 202. The thread end of the suture is clamped by the operator with clamps or tweezers and led out from the outside of the urethra together with the inner thread end to complete a stitch. In this process, since the needle head is an integrated structure, the operator does not need to apply a clamping action, so the operation is more convenient; since the needle head and the threading hole 301 always pass through the needle entry hole 203 of the other clamp head 202, the operator can quickly and accurately find / control the suture thread end, thereby quickly and accurately completing a stitch.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
