Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a surgical wire pliers. Background Art

[0002] Blunt separation and ligation of both ends before separating tissues is a commonly used separation method in abdominal surgery. During the operation, the doctor will use right-angle forceps or separation forceps to separate blood vessels, lymphatic vessels, nerves and other tissues. The wire forceps will pass the ligature to the right-angle forceps and then pull it around the tissue to complete the knot at one end. After that, the other end will be re-ligated with the wire in the same way before the tissue can be safely separated. Especially when separating some large abdominal blood vessels and deep tissues, in order to ensure the firmness of the tissue ends and reduce complications, doctors often use two sutures at the proximal end to strengthen the anastomosis; currently, conventional right-angle forceps or separation forceps pass two sutures through the tissue and tie a knot at the same time. This operation is relatively difficult and easily leads to chaotic entanglement of the silk threads, and it is impossible to complete the ligation of both ends at one time. In fact, the sutures can only be passed through the tissue twice and then knotted. During the operation, it is necessary to repeatedly separate the tissue and then tie the thread. Especially when the visual exposure is poor or difficult to expose in the deeper part of the abdomen, the separation and knotting are more difficult. Repeated threading may not be able to find the original separation path, and the tissue needs to be separated again, resulting in additional tissue damage, bleeding, lymph leakage and other complications. At the same time, especially in the case of blocking the liver portal or large blood vessels, the operation needs to race against time, and repeated threading also wastes more operation time. Therefore, if a wire-carrying forceps that can carry two threads at a time can be designed, it will be of great significance to save operation time and avoid unnecessary tissue damage. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a surgical wire pliers which does not need to repeat the threading action twice and is not easy to cause the wire to be tangled.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A surgical wire pliers comprises a pair of pliers arms connected by hinges, the pliers arms having an operating end and a clamping end, and the two pliers arms are provided with a clamping unit, a rotating handle, a steel wire rope and a spring; the clamping unit is arranged on the clamping end of the pliers arm, the clamping unit comprises a wire clamping part, a connecting hole and a traction part, the connecting hole is located between the wire clamping part and the traction part, and the connecting hole is provided with a rotating shaft hinged to the pliers arm; the rotating handle is rotatably connected to the operating end of the pliers arm; one end of the steel wire rope is connected to the traction part, and the other end of the steel wire rope is connected to the rotating handle; the spring sleeve is arranged on the outside of the steel wire rope, one end of the spring is connected to the traction part, and the other end is connected to the pliers arm.

[0006] Furthermore, an inner channel for passing the steel wire rope is arranged inside the clamp arm, and the inner channel is provided with openings for extending the steel wire rope at the operating end and the clamping end.

[0007] Furthermore, a mounting groove is provided on the side surface of the clamping end, and the clamping unit is arranged in the mounting groove.

[0008] Furthermore, toothed surfaces are provided on the mounting groove of the clamping end and on the wire clamping portion.

[0009] Furthermore, an elastic strip is provided between the operating end and the rotating handle, and the operating end, the rotating handle and the elastic strip are connected to form a ring shape.

[0010] Furthermore, a through hole is provided on the traction part for passing through the end of the steel wire rope, and a protrusion is provided at the end of the steel wire rope, and the size of the protrusion is larger than the through hole.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] like Figure 1 to Figure 4 As shown, the surgical wire pliers of this embodiment include a pair of pliers arms 1 connected by hinges, the pliers arms 1 having an operating end 101 and a clamping end 102, and both pliers arms 1 are provided with a clamping unit 2, a rotating handle 4, a steel wire 6 and a spring 9. The clamping unit 2 is provided on the clamping end 102 of the pliers arm 1, and the clamping unit 2 includes a clamping portion 201, a connecting hole 11 and a traction portion 202, the connecting hole 11 is located between the clamping portion 201 and the traction portion 202, and the connecting hole 11 is provided with a rotating shaft 10 hinged to the pliers arm 1. The rotating handle 4 is rotatably connected to the operating end 101 of the pliers arm 1. One end of the steel wire 6 is connected to the traction portion 202, and the other end of the steel wire 6 is connected to the rotating handle 4; the spring 9 is sleeved on the outside of the steel wire 6, one end of the spring 9 is connected to the traction portion 202, and the other end is connected to the pliers arm 1.

[0021] When the surgical wire clamp is not in operation, the spring 9 exerts a force on the traction part 202 of the clamping unit 2, so that the clamping part 201 and the clamping end 102 are close to each other. When the suture needs to be clamped, the handle 4 can be rotated to drive the wire rope 6 to pull the traction part 202, and the clamping unit 2 is rotated to make the clamping part 201 and the clamping end 102 relatively apart and open. After the head of the suture is placed between the clamping part 201 and the clamping end 102, the handle 4 is released, and the clamping unit 2 clamps the suture between the clamping part 201 and the clamping end 102 under the action of the spring 9, so that the two sutures can be passed through the tissue at the same time.

[0022] Among them, in order to better pull the clamping unit 2 with the wire rope 6 and reduce external influences, an internal channel for passing the wire rope 6 is provided inside the clamp arm 1, and the internal channel is provided with openings for extending the wire rope 6 on the operating end 101 and the clamping end 102. Since it is difficult to pass the wire rope 6 through the hinge of the two clamp arms 1, the wire rope 6 can pass through and bypass the hinge of the clamp arm 1, thereby not affecting the rotation of the clamp arm 1.

[0023] In order to facilitate the fitting of the clamping ends 102 on the two clamp arms 1 and reduce the protrusion of the clamping unit 2, a mounting groove 3 can be provided on the side of the clamping end 102, and the clamping unit 2 is arranged in the mounting groove 3. The mounting groove 3 of the clamping end 102 and the clamping part 201 are both provided with tooth surfaces 12 to increase friction resistance.

[0024] An elastic strip 5 is provided between the operating end 101 and the rotating handle 4. The operating end 101, the rotating handle 4 and the elastic strip 5 are connected in a ring shape, so that the rotating handle 4 is restricted in the rotation direction away from the operating end 101, thereby facilitating the rotation operation of the two clamp arms 1. Specifically, the elastic strip 5 can be a rubber rope, and the rubber rope is bound and connected by setting fixing holes at the ends of the operating end 101 and the rotating handle 4.

[0025] The traction part 202 is provided with a through hole 8 passing through the end of the wire rope 6. The end of the wire rope 6 is provided with a protrusion 7. The size of the protrusion 7 is larger than the through hole 8. When the wire rope 6 is pulled, the protrusion 7 generates a force on the traction part 202, thereby driving the rotation of the clamping unit 2.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
