Description

Technical Field

[0001] This utility model relates to the field of vascular ligation clip technology, specifically to an anti-dislodgement vascular ligation clip. Background Technology

[0002] Hemostasis is a core technique in basic surgical procedures. Surgical procedures on any part of the human body involve bleeding and hemostasis. Traditional methods such as ligation, suturing, packing, and thermal hemostasis still play an important role. Vascular clips, hemostatic gauze, and staplers developed based on these methods are also widely used. Patent CN201721257827.6 discloses an anti-dislodgement ligation clip, in which the upper and lower clamping arms have interlocking anti-slip grooves and protrusions. When the upper and lower clamping arms are closed, the anti-slip grooves and protrusions interlock, increasing the clamping area and placing the clamped tissue on different surfaces, effectively preventing lateral slippage of the blood vessel. However, when using the ligation clip, the blood vessel can easily slide and shift along the inner wall of the clip as it closes, affecting the ligation. Therefore, we propose an anti-dislodgement ligation clip. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an anti-dislodgement ligation blood vessel clip.

[0004] The technical solution adopted by this utility model to solve its technical problem is an anti-dislodgement ligation vascular clip, including a clip body. The inner wall surface of the clip body is provided with an arc-shaped groove, and the inner wall surface of the clip body is integrally constructed with an arc-shaped strip that fits the arc-shaped groove. The outer wall surface of the clip body is provided with a groove that communicates with the arc-shaped groove, and there are two sets of grooves. The outer wall surface of the clip body is integrally constructed with a protrusion that fits the groove, and there are two sets of protrusions.

[0005] The clamp body is provided with a sliding hole that communicates with the arc-shaped groove, and an arc-shaped block for auxiliary positioning is slidably installed in the sliding hole. A spring is fitted at one end of the arc-shaped block located in the sliding hole, and a cover strip for sealing the sliding hole is provided on the outer wall surface of the clamp body.

[0006] By adopting the above technical solution, when using the vascular clamp for ligation, the groove on the clamp body facilitates the sliding of the blood vessel, which provides a certain limiting performance for the blood vessel. As the clamp body closes, the arc strip and arc groove on the inner wall of the clamp body can fit together, thereby clamping and ligating the blood vessel. At the same time, the protrusion and groove on the clamp body can fit together and cooperate with the arc strip and arc groove, thereby facilitating double ligation, improving the ligation and hemostasis effect, and making the vascular clamp more convenient to use.

[0007] When the blood vessel slides into the groove connected to the arc-shaped groove, and the clamp closes and causes the arc-shaped strip and the arc-shaped groove to fit together, the spring in the sliding hole in the clamp facilitates the pushing of the arc-shaped block, so that one end of the arc-shaped block extends out of the sliding hole under the reaction force, and facilitates the cooperation between the arc-shaped block and the arc-shaped block, thereby improving the ligation effect when ligating the blood vessel, thus improving the stability of the blood vessel clamp during use, and the cover strip on the outside of the clamp is easy to swing open and close, which facilitates the sealing and protection of the structure in the sliding hole.

[0008] Specifically, the outer end surface of the clamp body is integrally constructed with an ear block for limiting the position, and a locking hole that fits the ear block is opened at the outer periphery of the clamp body away from the ear block.

[0009] By adopting the above technical solution, when the clamp is closed, it can drive the ear block at one end to engage and fit with the clasp at the other end, so that the clamp can close more stably and facilitate the ligation of blood vessels.

[0010] Specifically, straight holes are provided on the outer wall surface of the ear block and the outer end surface of the clamp body, and the straight holes are connected to the card holes.

[0011] By adopting the above technical solution, after the ear block and the locking hole fit together, the straight hole on the outer periphery of the ear block can correspond to the straight hole on the outer side of the clamp body, which facilitates the insertion of other structures. Thus, after the clamp body is closed and locked, the closed position can be fixed again, so that the clamp body will not open during use and it is convenient to lock the clamp body.

[0012] Specifically, the arc-shaped block has an anti-slip groove at one end located in the arc-shaped groove, and there are multiple sets of anti-slip grooves.

[0013] By adopting the above technical solution, the anti-slip grooves on the surface of the arc-shaped block can improve the anti-slip performance of the arc-shaped block, thereby improving the stability of ligation when the arc-shaped block and the arc-shaped strip cooperate with each other.

[0014] Specifically, the inner wall surface of the clamp is integrally constructed with anti-slip strips located on both sides of the arc-shaped groove, and there are multiple sets of anti-slip strips.

[0015] By adopting the above technical solution, the multiple anti-slip strips on the outside of the clamp body facilitate auxiliary positioning, enabling the ligation clamp to ligate blood vessels more stably.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of arc grooves, arc strips, grooves and protrusions, allows the grooves on the clamp body to facilitate the sliding of blood vessels when using the ligation vascular clamp, providing a certain limiting performance for the blood vessels. As the clamp body closes, the arc strips and arc grooves on the inner wall of the clamp body can fit together, thereby clamping and ligating the blood vessels. At the same time, the protrusions and grooves on the clamp body can fit together and cooperate with the arc strips and arc grooves, thereby facilitating double ligation, improving the ligation and hemostasis effect, and making the ligation vascular clamp more convenient to use.

[0018] 2. The technical solution of this application, through the design of sliding holes, arc-shaped blocks, springs, and locking holes, allows the blood vessel to slide into the groove connected to the arc-shaped groove. When the clamp closes and the arc-shaped strip and the arc-shaped groove are engaged with each other, the spring in the sliding hole of the clamp can easily push the arc-shaped block, so that one end of the arc-shaped block extends out of the sliding hole under the reaction force, and can easily cooperate with the arc-shaped block, thereby improving the ligation effect when ligating blood vessels. This improves the stability of the blood vessel clamp during use. In addition, the cover strip on the outside of the clamp can be easily opened and closed by swinging, which facilitates the sealing and protection of the structure in the sliding hole.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: an anti-dislodgement ligation vascular clip, including a clip body 1, an arc-shaped groove 2 is formed on the inner wall surface of the clip body 1, and an arc-shaped strip 3 is integrally formed on the inner wall surface of the clip body 1 to fit the arc-shaped groove 2, a groove 4 connected to the arc-shaped groove 2 is formed on the outer wall surface of the clip body 1, and there are two sets of grooves 4, and a protrusion 5 is integrally formed on the outer wall surface of the clip body 1 to fit the groove 4, and there are two sets of protrusions 5; a sliding hole 6 connected to the arc-shaped groove 2 is provided in the clip body 1, and an arc-shaped block 7 for auxiliary positioning is slidably installed in the sliding hole 6, a spring 8 is assembled at one end of the arc-shaped block 7 located in the sliding hole 6, and a cover strip 12 for sealing the sliding hole 6 is provided on the outer wall surface of the clip body 1.

[0026] When using the ligation clamp, the groove 4 on the clamp body 1 facilitates the sliding of the blood vessel, providing a certain limiting performance for the blood vessel. As the clamp body 1 closes, the arc-shaped strip 3 and the arc-shaped groove 2 on the inner wall of the clamp body 1 can fit together, thereby clamping and ligating the blood vessel. At the same time, the protrusion 5 on the clamp body 1 and the groove 4 can fit together and cooperate with the arc-shaped strip 3 and the arc-shaped groove 2, thereby facilitating double ligation, improving the ligation and hemostasis effect, and making the ligation clamp more convenient to use.

[0027] When the blood vessel slides into the groove 4 connected to the arc-shaped groove 2, and the clamp body 1 closes and drives the arc-shaped strip 3 to fit with the arc-shaped groove 2, the spring 8 in the sliding hole 6 in the clamp body 1 can easily push the arc-shaped block 7, so that one end of the arc-shaped block 7 extends out of the sliding hole 6 under the reaction force, and can easily cooperate with the arc-shaped block 7, thereby improving the ligation effect when ligating blood vessels, thus improving the stability of the blood vessel clamp during use, and the cover strip 12 on the outside of the clamp body 1 can be easily opened and closed, which is convenient for sealing and protecting the structure in the sliding hole 6.

[0028] like Figure 1 and Figure 2 As shown, the outer end surface of the clamp 1 is integrally constructed with an ear block 10 for limiting, and the end of the clamp 1 away from the ear block 10 is provided with a locking hole 9 that fits with the ear block 10.

[0029] When in use, when the clamp 1 is closed, it can drive the ear block 10 at one end to engage with the locking hole 9 at the other end, so that the clamp 1 can close more stably and facilitate the ligation of blood vessels.

[0030] like Figure 1 and Figure 2 As shown, straight holes 13 are provided on the outer wall surface of the ear block 10 and the outer end surface of the clamp 1, and the straight holes 13 are connected to the card holes 9.

[0031] When in use, after the ear block 10 and the locking hole 9 fit together, the straight hole 13 on the outer periphery of the ear block 10 can correspond to the straight hole 13 on the outer side of the clamp 1, making it easy for other structures to be inserted. Thus, after the clamp 1 is closed and locked, the closed position can be fixed again, so that the clamp 1 will not be opened during use, and it is easy to lock the clamp 1.

[0032] like Figure 1 and Figure 3 As shown, the arc-shaped block 7 has an anti-slip groove 11 at one end located in the arc-shaped groove 2, and there are multiple sets of anti-slip grooves 11.

[0033] When in use, the anti-slip grooves 11 on the surface of the arc block 7 help to improve the anti-slip performance of the arc block 7, thereby improving the stability of ligation when the arc block 7 and the arc strip 3 cooperate with each other.

[0034] like Figure 1 and Figure 2 As shown, the inner wall surface of the clamp 1 is integrally constructed with anti-slip strips 14 located on both sides of the arc-shaped groove 2, and there are multiple sets of anti-slip strips 14.

[0035] When in use, the multiple anti-slip strips 14 on the outside of the clamp body 1 facilitate auxiliary positioning, enabling the ligation clamp to ligate blood vessels more stably.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in the appropriate positions. When using the vascular clamp for ligation, the groove 4 on the clamp body 1 facilitates the sliding of the blood vessel, providing a certain degree of restraint. As the clamp body 1 closes, the arc-shaped strip 3 and arc-shaped groove 2 on the inner wall of the clamp body 1 engage with each other, thereby clamping and ligating the blood vessel. Simultaneously, the protrusion 5 on the clamp body 1 engages with the groove 4 and cooperates with the arc-shaped strip 3 and arc-shaped groove 2, facilitating double ligation and improving the hemostatic effect. This makes the ligation clamp more convenient to use. When the blood vessel slides into the groove 4 connected to the arc groove 2, and the clamp body 1 closes and drives the arc strip 3 to fit with the arc groove 2, the spring 8 in the sliding hole 6 in the clamp body 1 can easily push the arc block 7, so that one end of the arc block 7 extends out of the sliding hole 6 under the reaction force and can easily cooperate with the arc block 7, thereby improving the ligation effect when ligating blood vessels and improving the stability of the ligation clamp during use. In addition, the cover strip 12 on the outside of the clamp body 1 can be easily opened and closed by swinging, which is convenient for sealing and protecting the structure in the sliding hole 6.
