Description

Technical Field

[0001] This utility model relates to the field of absorbable closure technology, specifically to biocompatible absorbable closures. Background Technology

[0002] Biocompatible absorbable closure devices are medical devices whose main feature is that they can be absorbed in the body, thereby reducing the need for secondary surgery. These closure devices are usually made of biodegradable materials, such as bioabsorbable polylactic-co-glycolic acid, which can gradually degrade in the body and eventually be absorbed by the body, reducing the long-term impact on patients.

[0003] Existing absorbable closures lack a robust self-locking mechanism, sometimes resulting in insecure closure or even detachment, causing unnecessary trouble and inconvenience. Therefore, we propose a biocompatible absorbable closure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a biocompatible absorbable closure, which solves the problem that absorbable closures lack a perfect self-locking structure during use, sometimes leading to insecure closure or even detachment, causing unnecessary trouble.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A biocompatible absorbable closure device includes a connecting part. A lower arm and an upper arm are sequentially provided on the outer side of the connecting part. Anti-slip protrusions are fixedly connected at equal intervals to one side of the lower arm and one side of the upper arm. A fixing seat is fixedly connected to the outer side of the lower arm. A storage groove is provided inside the fixing seat, and a spring is provided inside the storage groove. A connecting seat is fixedly connected to one side of the upper arm, and a limiting groove is provided inside the connecting seat to cooperate with the spring. The lower and upper arms assist in the closure of blood vessels. The anti-slip protrusions effectively prevent slippage of blood vessels or tissues. The spring, entering the limiting groove, limits and fixes the lower and upper arms during closure, preventing insecure closure and slippage after closure.

[0007] Preferably, the number of anti-slip protrusions is twelve, and the twelve anti-slip protrusions are symmetrically distributed. The multiple sets of anti-slip protrusions can effectively prevent slippage of blood vessels or tissues.

[0008] Preferably, the anti-slip protrusion has a hemispherical structure, which can prevent damage to blood vessels or tissues.

[0009] Preferably, a first clamping block is fixedly connected to one side of the lower arm, and a second clamping block is fixedly connected to one side of the upper arm. The first and second clamping blocks can be used in conjunction with clamping pliers to facilitate closing operations.

[0010] Preferably, the connecting seat has a connecting groove inside that works with the fixed seat. The connecting groove allows it to work with the fixed seat, facilitating the limiting and fixing of the lower arm and the upper arm.

[0011] Preferably, the connecting part has an arc-shaped structure, which facilitates the closure between the lower arm and the upper arm.

[0012] This invention provides a biocompatible absorbable closure. Compared with the prior art, it has the following advantages:

[0013] Beneficial effects:

[0014] 1. This biocompatible absorbable closure device is made of biodegradable materials, which can be completely absorbed, rarely causing rejection reactions, leaving no foreign objects in the body, and has hemispherical anti-slip protrusions on the lower and upper arms to effectively prevent slippage of blood vessels or tissues.

[0015] 2. This biocompatible absorbable closure device, through the setting of a fixing seat, storage slot, spring piece, connecting seat, connecting slot and limiting slot, realizes the function of limiting and fixing it when the two arms are closed, avoiding the phenomenon of insecure closure, preventing slippage after closure, and facilitating use.

[0021] 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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution:

[0023] A biocompatible absorbable closure device includes a connecting part 8. A lower arm 1 and an upper arm 7 are sequentially arranged on the outer side of the connecting part 8. Anti-slip protrusions 2 are fixedly connected at equal intervals to one side of the lower arm 1 and one side of the upper arm 7. A fixing seat 4 is fixedly connected to the outer side of the lower arm 1. A storage groove 9 is provided inside the fixing seat 4, and a spring piece 10 is provided inside the storage groove 9. A connecting seat 5 is fixedly connected to one side of the upper arm 7, and a limiting groove 12 that cooperates with the spring piece 10 is provided inside the connecting seat 5. The lower arm 1 and upper arm 7 can assist in the closure of blood vessels. The anti-slip protrusions 2 effectively prevent slippage of blood vessels or tissues. The spring piece 10, entering the limiting groove 12, can limit and fix the lower arm 1 and upper arm 7 when they are closed, avoiding insecure closure and preventing slippage after closure.

[0024] Furthermore, there are twelve anti-slip protrusions 2, which are symmetrically distributed. The multiple sets of anti-slip protrusions 2 can effectively prevent slippage of blood vessels or tissues.

[0025] Furthermore, the anti-slip protrusion 2 has a hemispherical structure, which can prevent damage to blood vessels or tissues.

[0026] Furthermore, a first clamping block 3 is fixedly connected to one side of the lower arm 1, and a second clamping block 6 is fixedly connected to one side of the upper arm 7. The first clamping block 3 and the second clamping block 6 can be used in conjunction with the clamping pliers to facilitate the closing operation.

[0027] Furthermore, the connecting seat 5 has a connecting groove 11 inside that works with the fixed seat 4. The connecting groove 11 allows it to work with the fixed seat 4, making it convenient to limit and fix the lower arm 1 and the upper arm 7.

[0028] Furthermore, the connecting part 8 has an arc-shaped structure, which facilitates the closure between the lower arm 1 and the upper arm 7.

[0029] In use, the first clamping block 3 and the second clamping block 6 can be used in conjunction with the clamping forceps to perform a closing operation. The lower arm 1 and the upper arm 7 can assist in the closure of the blood vessels. The anti-slip protrusion 2 can effectively prevent the blood vessels or tissues from slipping out. When closing between the lower arm 1 and the upper arm 7, the fixing seat 4 will enter the interior of the connecting groove 11. During the entry process, the spring piece 10 will be squeezed by the connecting seat 5 and enter the interior of the receiving groove 9. When the fixing seat 4 is fully entered into the connecting groove 11, the spring piece 10 will enter the interior of the limiting groove 12 due to elastic reset, thereby limiting and fixing the lower arm 1 and the upper arm 7 to avoid the phenomenon of insecure closure and prevent slippage after closure.
