Description

Technical Field

[0001] This invention belongs to the field of vascular clamp technology, specifically referring to a multifunctional vascular clamp and its usage method. Background Technology

[0002] Vascular forceps are key instruments used in surgery to clamp, occlude, or separate blood vessels and tissues. They control bleeding or expose the surgical field through the clamping action of the jaws and are widely used in various open and laparoscopic surgeries. Traditional vascular forceps are designed with mechanical clamping as their core function. Their structure usually consists of two openable arms with flat or blunt toothed jaws at the front and a collar at the rear for the surgeon's fingers to operate. Some models use a rack and pinion mechanism to temporarily fix the jaw opening angle.

[0003] However, existing hemostatic forceps have a highly limited function, only capable of performing basic clamping actions. During surgery, if it is necessary to remove accumulated blood or tissue fluid from the surgical field, the surgeon must pause the current operation and switch to a dedicated suction instrument. This process not only significantly prolongs the operation time and increases the patient's anesthesia risk, but also increases the probability of postoperative infection due to the frequent entry and exit of instruments from the surgical field, which disrupts the sterile environment. Summary of the Invention

[0004] In view of the above situation, in order to reduce the pipeline structure and reduce energy consumption and equipment costs, the present invention provides a multifunctional vascular clamp.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a multifunctional vascular forceps, including a first forceps arm and a second forceps arm. The first forceps arm and the second forceps arm are hinged by a pivot. The front end of the second forceps arm is fixedly connected to a second forceps mouth, and the rear end of the second forceps arm is fixedly connected to a first collar. The front end of the first forceps arm is fixedly connected to the first forceps mouth, and the rear end of the first forceps arm is fixedly connected to the second collar. A connecting channel is opened inside the first forceps arm on the side near the first forceps mouth. One end of the connecting channel is connected to a suction port, and the other end of the connecting channel is connected to a tubing connection port.

[0006] Furthermore, the liquid extraction port is located on the side wall of the first clamping mouth, and the angle between the liquid extraction port and the plane is 30°.

[0007] Furthermore, the tubing connection port is connected through to the outer wall of the first clamp arm.

[0008] Furthermore, a first rack is fixedly connected to the lower end of the side wall of the second clamp arm, and a second rack is fixedly connected to the lower end of the side wall of the first clamp arm, with the first rack and the second rack meshing with each other.

[0009] Furthermore, the upper sidewall of the second clamp arm is provided with a second raised texture, and the upper sidewall of the first clamp arm is provided with a first raised texture. The first raised texture and the second raised texture are arranged opposite to each other.

[0010] Furthermore, the hose connector is used to connect to the air extraction hose.

[0011] This solution also discloses a method for using a multifunctional vascular clamp, which mainly includes the following steps: Step 1: Insert your fingers into the first and second rings, and use the first and second jaws to firmly grip the target. The first and second raised grooves ensure that it will not slip off during the lifting process. The tubing connector is used to connect the suction tubing, which is connected to the suction port of the operating table to remove excess tissue fluid. Step 2: The angle between the suction port and the plane is 30° to prevent interference with the operation of the first and second jaws. The first and second raised textures can increase the friction of the clamping surface and prevent the object from moving. Step 3: When one of the serrations on the first rack and one of the serrations on the second rack mesh, the first and second clamp arms can be kept in a fixed position, that is, the opening angle of the first and second clamp jaws is kept at a certain position.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a multifunctional vascular clamp, achieving the following beneficial effects: (1) By setting up connection channels, tube heads and tubing connection ports, the suction tubing can be connected to extract excess tissue fluid, meeting various needs during surgery and improving the convenience and efficiency of surgery.

[0013] (2) The angle between the suction port and the plane is 30° to avoid affecting the operation of the first and second clamps, making the surgical operation more precise and smooth.

[0014] (3) The first raised texture and the second raised texture are set opposite to each other to increase the friction of the clamping surface, ensure that the lifting process is not easy to slip and improve the stability of operation.

[0015] (4) The first and second racks mesh with each other, which can keep the first and second clamp arms in a fixed position and fix the opening angle of the first and second clamp mouths, making the surgical operation convenient. Attached Figure Description

[0021] like Figures 1-4As shown, this invention proposes a multifunctional vascular clamp, including a first clamp arm 1 and a second clamp arm 2. The first clamp arm 1 and the second clamp arm 2 are hinged together by a pivot 5. The front end of the second clamp arm 2 is fixedly connected to a second clamping mouth 12. The lower end of the side wall of the second clamp arm 2 is fixedly connected to a first toothed rack 6. The lower end of the side wall of the first clamp arm 1 is fixedly connected to a second toothed rack 7. The first toothed rack 6 and the second toothed rack 7 mesh with each other. The rear end of the second clamp arm 2 is fixedly connected to a first collar 3. The front end of the first clamp arm 1 is fixedly connected to a first clamping mouth 11. The rear end of the first clamp arm 1 is fixedly connected to a second collar 4. A connecting channel 9 is opened on the side of the clamp arm 1 near the first clamping mouth 11. One end of the connecting channel 9 is connected to the liquid extraction port 8, which is located on the side wall of the first clamping mouth 11. The angle between the liquid extraction port 8 and the plane is 30°. The other end of the connecting channel 9 is connected to the tubing connection port 10, which is connected to the outer side wall of the first clamp arm 1. The upper side wall of the second clamp arm 2 is provided with a second raised texture 14, and the upper side wall of the first clamp arm 1 is provided with a first raised texture 13. The first raised texture 13 and the second raised texture 14 are arranged opposite to each other.

[0022] The hose connector 10 is used to connect the vacuum hose.

[0023] In practical use, fingers are inserted into the first collar 3 and the second collar 4, and the first jaw 11 and the second jaw 12 are used to firmly clamp the object. The tubing connection port 10 is used to connect to the suction tubing, which is connected to the suction port of the operating table to extract excess tissue fluid. The suction port 8 is at a 30° angle to the plane to prevent interference with the operation of the first jaw 11 and the second jaw 12. The first raised texture 13 and the second raised texture 14 can increase the friction of the clamping surface and prevent the object from moving. When one of the serrations on the first rack 6 and the second rack 7 are engaged, the first clamp arm 1 and the second clamp arm 2 can be kept in a fixed position, that is, the opening angle of the first jaw 11 and the second jaw 12 is kept at a certain position. The above is the overall working process of the present invention. This step can be repeated for the next use.
