Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a novel non-invasive hemostatic clip. Background Technology

[0002] In surgical procedures, hemostatic clips are commonly used to temporarily block blood flow to facilitate surgical manipulation or suturing. The design and quality of the hemostatic clip play a crucial role in protecting the blood vessel and achieving hemostasis. Existing non-invasive hemostatic clip devices, such as the one disclosed in application number CN201921766898.8, employ a simple and effective structural design, achieving good temporary vascular occlusion with relatively ideal hemostatic effects. However, in practical applications, existing hemostatic clips still have some shortcomings.

[0003] First, some non-invasive hemostatic clips are at risk of loosening during the fixation process. Since a certain amount of pressure is usually applied when clamping the clips, if the fixation mechanism is not stable enough during the operation, the clips may loosen or slip due to external force or movement, thereby affecting the hemostatic effect and even causing vascular damage.

[0004] Secondly, existing hemostatic clips may lack sufficient clamping force during operation, resulting in their inability to fully compress blood vessels or tissues, especially in larger blood vessels or in locations that are difficult to clamp, which can easily lead to incomplete hemostasis or unstable clamping. Summary of the Invention

[0005] The main purpose of this application is to provide a novel non-invasive hemostatic clip to solve the problem that existing hemostatic clips loosen and affect hemostatic effect due to unreliable fixation in practical applications.

[0006] To achieve the above objectives, according to one aspect of this application, a novel non-invasive hemostatic clip is provided.

[0007] The novel non-invasive hemostatic clip according to this application includes: a first base plate, a second base plate rotatably connected to the first base plate via a central shaft, and a fixing mechanism connected to the first base plate and the second base plate.

[0008] The first substrate has a bent first button portion at one end, and the second substrate has a bent second button portion at one end. The first button portion and the second button portion are symmetrical, and a spring is connected between the first button portion and the second button portion.

[0009] The fixing mechanism is connected to the side of the first substrate and the second substrate away from the first button portion and the second button portion; the fixing mechanism includes: an elastic connecting strip connected to the second substrate, a first fastening portion disposed on the first substrate, and a second fastening portion connected to the elastic connecting strip and detachably engaged with the first fastening portion.

[0010] Furthermore, the first fastening part has a locking groove, and a limiting protrusion is provided in the locking groove; the second fastening part is externally fitted with the locking groove, and is externally provided with a limiting groove that engages with the limiting protrusion.

[0011] Furthermore, an arc-shaped portion is provided on the outer side of the bottom end of the second fastening part.

[0012] Furthermore, the first substrate and the second substrate are respectively provided with a first clamping portion and a second clamping portion on the inner side away from the first button portion and the second button portion, and a clamping jaw is formed between the first clamping portion and the second clamping portion.

[0013] Furthermore, both the first clamping part and the second clamping part are made of medical-grade elastic material TPE.

[0014] Furthermore, both the first clamping part and the second clamping part are provided with locking teeth on their surfaces, and the locking teeth on the first clamping part and the second clamping part are arranged in a staggered manner.

[0015] Furthermore, the surface of the tooth is arc-shaped.

[0016] Furthermore, both the first and second button sections are provided with anti-slip pads on their exteriors.

[0017] In this embodiment, the first and second fastening parts are used in a snap-fit ​​manner. Through the optimized snap-fit ​​design and elastic fixing mechanism, the stability of the hemostatic clip is enhanced. This ensures that the hemostatic clip will not loosen due to external force during use, thus ensuring continuous clamping force and stable hemostatic effect. This solves the problem of loosening and affecting the hemostatic effect of existing hemostatic clips due to unreliable fixing in practical applications. Attached Figure Description

[0031] Example 1

[0032] like Figure 1-4 As shown, this application relates to a novel non-invasive hemostatic clip, comprising: a first base plate 1, a second base plate 2, a first button portion 5, a second button portion 6, a spring 7, a fixing mechanism 4, a first fastening portion 42, a second fastening portion 43, an elastic connecting band 41, a first clamping portion 8, and a second clamping portion 9.

[0033] The first substrate 1 is rotatably connected to the second substrate 2 via a central shaft 3. A shaft connector is provided between the first substrate 1 and the second substrate 2, and the central shaft 3 is inserted into the shaft connector to axially connect the first substrate 1 and the second substrate 2. The first substrate 1 has a bent first button portion 5 at its end, and the second substrate 2 has a bent second button portion 6 at its end. The first button portion 5 and the second button portion 6 are symmetrically arranged and connected by a spring 7. The user can open and close the hemostatic clip by pressing either the first button portion 5 or the second button portion 6.

[0034] The fixing mechanism 4 is located on the side of the first substrate 1 and the second substrate 2 away from the first button portion 5 and the second button portion 6. The fixing mechanism 4 includes an elastic connecting strip 41, a first fastening portion 42 disposed on the first substrate 1, and a second fastening portion 43 detachably snapped into the first fastening portion 42. The elastic connecting strip 41 is connected to the second substrate 2 to ensure the stability of the fixing mechanism 4; the user can fix the hemostatic clip by snapping the first fastening portion 42 and the second fastening portion 43, which aims to ensure that the hemostatic clip can remain stable during the clamping operation and avoid loosening or insecure clamping due to external force.

[0035] In this embodiment, the elastic connecting strip 41 is connected to the second substrate 2 at one end and to the second fastening part 43, ensuring the stability of the second fastening part 43 during use. The elastic connecting strip 41 provides a certain elasticity, making the fixing mechanism more flexible during operation and providing a certain clamping force to ensure the clamping stability of the clamping openings of the first substrate 1 and the second substrate 2.

[0036] In this embodiment, the first snap-fit ​​part 42 and the second snap-fit ​​part 43 are used to engage in a snap-fit ​​manner. Through the optimized snap-fit ​​design and elastic fixing mechanism, the stability of the hemostatic clip is enhanced, thereby ensuring that the hemostatic clip will not loosen due to external force during use. This ensures continuous clamping force and stable hemostatic effect, and solves the problem of loosening and affecting the hemostatic effect of existing hemostatic clips due to unreliable fixing in practical applications.

[0037] In this embodiment, as shown in the figure, the first fastening part 42 has a locking groove 421, and a limiting protrusion 422 is provided in the locking groove 421; the second fastening part 43 is externally fitted with the locking groove 421, and is externally provided with a limiting groove 431 that engages with the limiting protrusion 422; this structural design can effectively prevent the hemostatic clip from loosening due to external force during use, thereby improving its stability in use.

[0038] In this embodiment, as shown in the figure, a first clamping part 8 and a second clamping part 9 are respectively provided on the inner side of the first substrate 1 and the second substrate 2, and a clamping jaw is formed between the first clamping part 8 and the second clamping part 9; when the hemostatic clamp is closed, the clamping jaw can accurately clamp the blood vessel or damaged tissue to ensure effective hemostasis.

[0039] In this embodiment, the first clamping part 8 and the second clamping part 9 are made of medical elastic material TPE. This material has good elasticity and biocompatibility, which can ensure that the clamping part can maintain sufficient clamping force during use, while avoiding excessive pressure on the tissue and reducing trauma.

[0040] As shown in the figure, the surfaces of the first clamping part 8 and the second clamping part 9 are both provided with locking teeth 10, and the locking teeth 10 are staggered. The design of the locking teeth 10 can effectively improve the clamping force, prevent the hemostatic clamp from sliding or loosening, and improve its stability and reliability.

[0041] The surface of the clip 10 is curved, which allows for better contact with tissue and ensures that the hemostatic clip is more comfortable and stable to use.

[0042] To enhance the ease of operation of the hemostatic clip, anti-slip pads 11 are provided on the outside of both the first button part 5 and the second button part 6. The anti-slip pads 11 can effectively avoid operational difficulties caused by slipping hands, making it easier for users to use the hemostatic clip in emergency situations.

[0043] Example 2

[0044] This embodiment is based on embodiment 1. An arc-shaped part 432 is provided on the outer side of the bottom end of the second fastening part 43. The arc-shaped part 432 helps to improve the smoothness of the snap-fit ​​and can further increase the stability of the hemostatic clip after fixation, preventing the fastening part from being misaligned.

[0045] The device works as follows: After the hemostatic clamp is held at the target position, the user engages the first locking part 42 and the second locking part 43 together; the clamping part exerts pressure on the blood vessel or tissue to ensure the closure of the blood vessel, thereby achieving the effect of non-invasive hemostasis.

[0046] As can be seen from the above description, this application achieves the following technical effects: In the embodiments of this application, the first snap-fit ​​part 42 and the second snap-fit ​​part 43 are used in a snap-fit ​​manner. Through the optimized snap-fit ​​design and elastic fixing mechanism, the purpose of enhancing the fixing stability of the hemostatic clip is achieved. This ensures that the hemostatic clip will not loosen due to external force during use, thus ensuring continuous clamping force and stable hemostatic effect. This solves the problem that existing hemostatic clips loosen and affect the hemostatic effect due to unreliable fixing in practical applications.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
