Description

Technical Field

[0001] This utility model relates to the field of vascular clamp technology, specifically to a novel non-invasive vascular occlusion clamp. Background Technology

[0002] Vascular clamps are specialized instruments commonly used in vascular surgery. They are primarily used to temporarily clamp blood vessels during surgery to control bleeding or provide operating space. Vascular clamps are typically made of high-quality stainless steel, which is corrosion-resistant and fatigue-resistant, ensuring safety for long-term use. Common vascular clamps come in various structures, such as straight and curved types, to suit different surgical needs.

[0003] However, traditional vascular clamps require the index finger and thumb to continuously squeeze and apply force to control the opening and closing of the clamping end. Prolonged operation can easily lead to hand fatigue and soreness, thus affecting the smooth progress of the operation. Doctors often face high operational difficulty in emergency situations. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this utility model is to propose a novel non-invasive vascular occlusion clamp. This novel non-invasive vascular occlusion clamp can open and close the clamp by pressing and releasing the push rod, thereby simplifying the operation steps, improving efficiency, and ensuring stable and reliable vascular occlusion.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel non-invasive vascular occlusion forceps, comprising a cylindrical body, two handles symmetrically mounted on the outer wall of the cylindrical body, a push rod penetrating through the top of the cylindrical body, a fixing rod fixedly connected to the inner wall of the cylindrical body, two clamping plates symmetrically slidably mounted on the fixing rod, ball bearings mounted on adjacent sides of the two clamping plates, and springs fixedly connected to opposing sides of the two clamping plates, the springs being sleeved on the outside of the fixing rod, and a tapered rod fixedly connected to one bottom end of the push rod, the outer wall of the tapered rod sliding against the ball bearings.

[0007] Preferably, both of the two clamping plates have concave and convex clamping teeth on adjacent sides and near the bottom.

[0008] Preferably, the bottom of the handle is provided with an arc-shaped groove.

[0009] Preferably, a pressure plate is fixedly connected to one end of the push rod.

[0010] Preferably, a limiting ring is fixedly connected to each of the two opposing sides of the clamping plates, and one end of the spring is located inside the limiting ring.

[0011] Preferably, the top of the pressure plate is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the vascular clamp moves the tapered rod fixed at the bottom downward by manually pressing down the push rod, pushing the clamp to open. The ball bearings on the outer wall of the tapered rod slide with the clamp on the adjacent side, providing blocking space. After releasing the push rod, the spring returns the clamp to its original position, and the push rod resets, thus achieving vascular clamping and fixation. The operation steps can be simplified and efficiency improved by a single pressing and releasing operation, ensuring stable and reliable vascular occlusion. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 The present invention provides a novel non-invasive vascular occlusion clamp, comprising: a cylindrical body 1.

[0020] Among them, such as Figure 2 and Figure 4As shown, two handles 4 are symmetrically installed on the outer wall of the cylinder 1. A push rod 2 passes through the top of the cylinder 1. A fixed rod 10 is fixedly connected to the inner wall of the cylinder 1. Two clamping plates 3 are symmetrically slidably installed on the fixed rod 10. A ball bearing 9 is installed on the adjacent side of the two clamping plates 3. A spring 12 is fixedly connected to the opposing side of the two clamping plates 3. The spring 12 is sleeved on the outside of the fixed rod 10. A tapered rod 8 is fixedly connected to one end of the bottom of the push rod 2. The outer wall of the tapered rod 8 slides against the ball bearing 9.

[0021] In use, by manually pressing down the push rod 2, the tapered rod 8 moves downward, and the outer wall of the tapered rod 8 slides against the ball bearings 9 on the adjacent side of the two clamps 3, thereby pushing the two clamps 3 to open to both sides to provide space for blocking the blood vessel. When the push rod 2 is released, the elastic force of the spring 12 pushes the clamps 3 back to their original position, and at the same time, the push rod 2 returns to its original position, thereby achieving the clamping and fixing of the blood vessel by the two clamps 3.

[0022] Furthermore, refer to Figure 2 The bottom of the handle 4 is provided with an arc-shaped groove 5. When the operator holds the handle 4, the arc-shaped groove 5 can better fit the shape of the fingers, making it easier for the operator to apply pressure. The top end of the push rod 2 is fixedly connected to a pressure plate 6, which can increase the pressing area of ​​the fixed rod 10.

[0023] It should be noted that the top of the pressure plate 6 is provided with anti-slip texture 7, which can increase the friction of the surface of the pressure plate 6 and make it easier to press.

[0024] In this embodiment, as Figures 1-3 As shown, each of the two clamps 3 has concave and convex clamping teeth 13 on one side of each other and near the bottom. The ends of the two clamps 3 cooperate with each other through the concave and convex clamping teeth 13 to block and compress the blood vessels.

[0025] Furthermore, limit rings 11 are fixedly connected to the opposing sides of the two clamping plates 3. One end of the spring 12 is located inside the limit ring 11. The limit ring 11 can limit the position of the end of the spring 12 and prevent the end of the spring 12 from shifting.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: The vascular occlusion clamp moves the tapered rod 8 fixedly connected to its bottom downward by manually pressing down the push rod 2. The outer wall of the tapered rod 8 slides against the ball bearings 9 on the adjacent side of the two clamps 3, thereby pushing the two clamps 3 to open to both sides to provide space for occlusion of the blood vessel. When the push rod 2 is released, the elastic force of the spring 12 pushes the clamps 3 back to their original position, and at the same time, the push rod 2 returns to its original position, thereby achieving the clamping and fixation of the blood vessel by the two clamps 3, reducing the number of operation steps and improving work efficiency, and ensuring stable and reliable operation.

[0027] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
