Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a suture auxiliary clip. Background Art

[0002] When a tumor invades a large artery (such as the pulmonary artery), the tumor is removed after blocking the blood vessels to ensure complete resection. Of course, a portion of the blood vessel wall invaded by the tumor is also removed, forming a hole in the vessel wall. To ensure the integrity of the vessel, the doctor will remove a portion of the human pericardium as repair material and sew a pericardial patch into the hole in the vessel wall.

[0003] However, it is extremely difficult to sew the pericardial patch to the blood vessel wall. Due to the narrow field of view, it is extremely difficult for assistants to provide assistance. The surgeon usually completes the suturing process independently. Since there is no tension support during the suturing process, the surgeon can only use tweezers to clamp the pericardial patch while using a needle to sew the blood vessel wall and the pericardial patch. This may make it inconvenient to sew the holes in the blood vessel wall, and the suturing time is longer and the suturing efficiency is lower. Utility Model Content

[0004] In order to solve the above technical problem that it is inconvenient for the surgeon to sew up the hole in the blood vessel wall, the utility model provides a suturing auxiliary clip.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The suture auxiliary clamp includes a base plate and two clamping components, wherein the clamping components include an operating rod, a connecting plate, a clamping plate and an elastic member; the elastic member is fixedly connected to the base plate and the connecting plate, and the connecting plate is fixedly connected to the clamping plate and the operating rod.

[0007] Furthermore, the elastic member includes an arc-shaped spring piece and an inclined plate, the arc-shaped spring piece is fixedly connected to the inclined plate and the connecting plate, and the inclined plate is fixedly connected to the bottom plate.

[0008] Furthermore, an upper operating port is provided on the operating lever.

[0009] Furthermore, a lower operating port is provided on the operating lever.

[0010] Furthermore, the base plate is made of titanium alloy.

[0011] Furthermore, the material of the splint is titanium alloy.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model adopts a bottom plate and two clamping components to clamp the pericardial patch and the blood vessel wall, avoiding the need for the surgeon to use tweezers to clamp the pericardial patch when suturing the blood vessel wall and the pericardial patch, thereby improving the convenience of mending holes in the blood vessel wall, shortening the mending time, and solving the problem of the surgeon being unable to mend holes in the blood vessel wall;

[0014] 2. The utility model adopts an upper operating port and a lower operating port to facilitate the surgeon to pinch the operating lever at different positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0021] Example:

[0022] The specific implementation process of the utility model: Suture auxiliary clip, such as Figure 1-Figure 3 As shown, it includes a base plate 1 and two clamping assemblies, and the clamping assembly includes an operating rod 4, a connecting plate 3, a clamping plate 2 and an elastic member; the elastic member is fixedly connected to the base plate 1 and the connecting plate 3, and the connecting plate 3 is fixedly connected to the clamping plate 2 and the operating rod 4.

[0023] like Figure 2-Figure 4As shown, when the hole 11 on the vascular wall 9 needs to be repaired, first pinch the two operating rods 4 close to each other, the two splints 2 will move upward away from the base plate 1, and then the vascular wall 9 and the pericardial patch 10 are both located between the splints 2 and the base plate 1, and the vascular wall 9 and the pericardial patch 10 are respectively located at the two ends of the base plate 1, and then release the two operating rods 4, the two splints 2 will move downward close to the base plate 1, and form a clamp for the vascular wall 9 and the pericardial patch 10; at least three of the suture auxiliary clips of the present invention are used to clamp the pericardial patch 10 and the vascular wall 9 in the hole 11 on the vascular wall 9, and then the surgeon can use a suture needle to suture the vascular wall 9 and the pericardial patch 10.

[0024] like Figure 1 and Figure 3 As shown, the elastic member includes an arc-shaped elastic piece 7 and an inclined plate 8 , the arc-shaped elastic piece 7 is fixedly connected to the inclined plate 8 and the connecting plate 3 , and the inclined plate 8 is fixedly connected to the bottom plate 1 .

[0025] When the two operating rods 4 are pinched and brought close to each other, the arc-shaped spring piece 7 will be bent. When the two operating rods 4 are released, the arc-shaped spring piece 7 will return to its original shape.

[0026] like Figure 1 As shown, the operating lever 4 is provided with an upper operating port 5 .

[0027] The upper operating port 5 allows the surgeon's fingers to grip the operating lever 4 more stably.

[0028] like Figure 1 As shown, the operating lever 4 is provided with a lower operating port 6 .

[0029] The lower operating port 6 can also allow the surgeon's fingers to hold the operating rod 4 more stably, preventing the fingers from sliding on the operating rod 4 easily.

[0030] The base plate 1 is made of titanium alloy.

[0031] The base plate 1 is made of titanium alloy, which can reduce the erosion of the base plate 1 by blood and increase the service life of the base plate 1.

[0032] The material of the splint 2 is titanium alloy.

[0033] The material of the splint 2 is titanium alloy, which can reduce the erosion of the splint 2 by blood and extend the service life of the splint 2.

[0034] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
