Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a resistance-free wire-passing clamp. Background Technology

[0002] During surgical procedures, especially laparoscopic surgery, the limited operating field and space make it difficult to operate hemostats or pose a risk of bleeding. Sometimes, it is necessary to ligate the blood vessel before proceeding to the next step. Currently, a common method involves using an angled hemostat head to wrap around the posterior wall of the dissected blood vessel and slightly tilt it upwards. A ligation suture is then placed on the other side of the vessel. The ligation suture is then pulled through the dissected vessel using the hemostat head and ligated.

[0003] The forceps of this type of hemostat are inconvenient to operate, making it difficult to pass the ligation suture around the already dissected blood vessel in one go. Furthermore, when using forceps to loop the suture through the blood vessel with the coil, the suture comes into contact with the blood vessel, and the excessive friction when pulling the suture may cause damage to the blood vessel or even rupture and bleeding. Utility Model Content

[0004] The purpose of this invention is to provide a resistance-free suture passer to solve the problem of easy vascular damage when pulling sutures in the prior art. The resistance-free suture passer of this invention will not come into contact with blood vessels when pulling sutures, avoiding damage to blood vessels caused by the pulling process of the suture, making the surgical procedure safer and more convenient.

[0005] This utility model provides a resistance-free wire guide, including a wire guide rod and a wire connector. The wire guide rod has a hollow internal structure and a wire-passing channel extending along its length. The wire connector is detachably connected to the wire-passing channel at the head end of the wire guide rod. One end of the wire is connected to the wire connector, and the other end passes through the wire-passing channel from the tail end of the wire guide rod.

[0006] As a preferred embodiment of this utility model, the head end of the wire guide rod is provided with a bent portion, the wire threading channel extends to the head end of the bent portion, and the wire connector is detachably connected to the head end of the bent portion.

[0007] As a preferred embodiment of this utility model, the angle between the bent portion and the main rod of the through rod is 60°-150°.

[0008] As a preferred embodiment of this utility model, the outer side of the connector has a marking color.

[0009] As a preferred embodiment of this utility model, a protrusion is provided at the tail end of the connector, and the protrusion engages with the wire passage at the head end of the bend.

[0010] As a preferred embodiment of this utility model, the protrusion of the connector is provided with a wiring hole, and one end of the wire is connected to the wiring hole.

[0011] As a preferred embodiment of this utility model, it also includes a handle, which is connected to the tail end of the wire guide rod, and the wire passes through the side wall of the tail end of the wire guide rod.

[0012] As a preferred embodiment of this utility model, the handle and the cable guide rod are an integral structure.

[0013] Compared with the prior art, the present invention has the following positive effects:

[0014] This utility model provides a resistance-free suture passer, comprising a suture rod and a suture connector. The suture rod has a hollow internal structure with a suture channel extending along its length. The suture connector is detachably connected to the suture channel at the head end of the suture rod. One end of the suture is connected to the suture connector, and the other end passes through the suture channel from the tail end of the suture rod. During operation, one end of the suture is connected to the suture connector, and the other end passes through the suture channel from the tail end of the suture rod. The suture passer is then slowly guided around the blood vessel and extended from its bottom using the head end of the suture passer. On the other side of the blood vessel, forceps or hemostatic forceps are used to remove the suture connector from the head end of the suture rod, pulling the suture along with it. Once the suture is pulled to the appropriate position, the suture rod is withdrawn, and subsequent surgical procedures can then be performed. By using the threading channel inside the thread guide, the suture is passed from one side of the blood vessel to the other side. After the suture is pulled into place, the thread guide is withdrawn. The entire suture process hides the suture inside the thread guide, so it does not come into contact with the blood vessel when the suture is pulled. This avoids pulling the blood vessel and causing damage during the suture pulling process, making the surgical procedure safer and more convenient. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Example 1:

[0025] This embodiment provides a resistance-free wire guide clamp, such as Figures 1-4 As shown, it includes a cable guide rod 1 and a cable connector 2. The cable guide rod 1 has a hollow internal structure and a cable-passing channel 11 extending along its length. The cable guide rod 1 can be configured as a telescopic structure, such as a telescopic structure with a sleeve connection, so that the length of the cable guide rod can be adjusted according to different scenarios and depths.

[0026] The connector 2 is detachably connected to the threading channel 11 at the head end of the threading rod 1. One end of the thread 4 is connected to the connector 2 and the other end passes through the threading channel 11 from the tail end of the threading rod 1.

[0027] In this embodiment, the resistance-free suture forceps connect one end of the suture 4 to the suture head 2, and the other end passes through the suture channel 11 from the tail end of the suture rod 1. The head of the suture forceps is slowly used to bypass the blood vessel 5 and extend it from its bottom. On the other side of the blood vessel, the suture head 2 is removed from the head end of the suture rod 1 using forceps or hemostatic forceps, and the suture is pulled out together. After the suture 4 is pulled to the appropriate position, the suture rod 1 is withdrawn, and then the subsequent surgical operation is performed.

[0028] In this embodiment, the thread 4 is passed around the blood vessel 5 from one side to the other side by means of the thread channel 11 inside the thread guide rod 1. After the thread is pulled into place, the thread guide rod 1 is withdrawn. The entire thread guiding process hides the thread in the thread guide rod 1. The thread will not come into contact with the blood vessel when it is pulled, thus avoiding damage to the blood vessel caused by the pulling process of the thread. This makes the operation safer and more convenient.

[0029] As a preferred embodiment, such as Figure 2 As shown, the head end of the wire guide rod 1 is provided with a bent portion 12. The wire passage 11 extends to the head end of the bent portion 12, and the wire connector 2 is detachably connected to the head end of the bent portion 12.

[0030] In this embodiment, the bent portion 12 and the main rod at the head end of the guide rod 1 form a certain angle, so as to facilitate the use of the bent portion 12 at the head end of the guide rod 1 to bypass the blood vessel 5, making the lead wire operation more convenient.

[0031] In one preferred embodiment, the angle between the bend 12 and the main stem of the guide rod 1 is 60°-150° to accommodate blood vessel operations at different angles. Preferably, the bend 12 and the main stem of the guide rod 1 are connected at a right angle.

[0032] Preferably, the bent portion 12 is smoothly connected to the main rod of the cable guide 1 via an arc segment. The bent portion 12 and the main rod of the cable guide 1 are at a right angle, making the cable passing operation more convenient.

[0033] In one preferred embodiment, the outer side of the connector 2 is marked with a color.

[0034] Specifically, the outer side of connector 2 can be red, green, yellow, etc.

[0035] In this embodiment, the outer side of the suture head 2 is marked with a color to make it easy to identify during the operation, so that the suture head 2 can be removed from the end of the suture rod 1 by using tweezers or hemostatic forceps and the suture 4 can be pulled, thereby improving the efficiency of the operation.

[0036] Specifically, connector 2 is made of inert material, which can be a safe plastic material.

[0037] As a preferred embodiment, such as Figure 4As shown, a protrusion 21 is provided at the tail end of the connector 2, and the protrusion 21 is engaged with the wire passage 11 at the head end of the bending part 12.

[0038] Preferably, the tip of the connector 2 is smooth.

[0039] In this embodiment, the connector 2 and the wire guide rod 1 are connected by a protrusion 21 engaging with the wire channel 11, so that the connector 2 does not need to be engaged too tightly when connected to the wire guide rod 1. The protrusion 21 can have a certain degree of elasticity to facilitate separation from the wire channel 11, making it easy to remove the connector 2 from the end of the wire guide rod 1.

[0040] As a preferred embodiment, such as Figure 4 As shown, the protrusion 21 of the connector 2 is provided with a wiring hole 22, and one end of the wire 4 is connected to the wiring hole 22.

[0041] It should be noted that the wiring hole 22 can be a retaining ring connected to the tail of the protrusion 21, or it can be a through hole provided on the protrusion 21, as long as it serves to fix the wire.

[0042] As a preferred embodiment, such as Figure 1 As shown, the resistance-free wire guide pliers of this embodiment also include a handle 3, which is connected to the tail end of the wire guide rod 1, and the wire 4 passes through the side wall of the tail end of the wire guide rod 1. In addition, the wire passage 11 can also extend to the tail end of the handle 3, so that the wire 4 passes through the tail end of the handle 3.

[0043] Preferably, the outer side of the handle 3 has anti-slip texture to facilitate hand operation.

[0044] In one preferred embodiment, the handle 3 and the cable guide rod 1 are an integral structure.

[0045] The handle 3 and the cable guide rod 1 are integrally formed and can be cast from corrosion-resistant metal material, resulting in low manufacturing costs.

[0046] This utility model of a resistance-free suture passer does not come into contact with blood vessels when pulling the suture. When the suture passer passes through the posterior wall of the blood vessel, the built-in suture simultaneously wraps around the posterior wall of the blood vessel, reducing the amount of manipulation and avoiding damage to the blood vessel caused by the pulling of the suture. At the same time, the suture passer has color-coded indicators for better identification and avoids secondary damage caused by forceful manipulation, making the surgical process safer and more convenient.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
