Description

Technical Field

[0001] This utility model relates to the technical field of applying or removing clamps or clips, and particularly to a clamping trigger for a ligation clamp. Background Technology

[0002] In surgical procedures, clamps are key instruments used to clamp and ligate blood vessels or tissues, and the feel of their triggers directly affects the accuracy and safety of the surgery.

[0003] Traditional clamping triggers are mostly made of metal or have a smooth plastic surface, resulting in a low coefficient of friction. During surgery, surgeons need to apply continuous force to maintain the clamping state. Especially in minimally invasive surgery, due to limited operating space, surgeons need to maintain a specific posture for a long time, which can easily lead to sweaty hands or slippage between gloves and instruments. This directly affects the accurate positioning and release of the ligation clip, increasing surgical risks. Therefore, we propose a clamping trigger for ligation clips. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a clamping trigger for ligation clips. This can solve the problem that traditional clamping triggers are mostly made of metal or have a smooth plastic surface, which has a low coefficient of friction. During the operation, the doctor needs to apply continuous force to maintain the clamping state. Especially in minimally invasive surgery, due to the limited operating space, the doctor needs to maintain a specific posture for a long time, which can easily lead to sweaty hands or slippage between the glove and the instrument, directly affecting the accurate positioning and release of the ligation clip and increasing the surgical risk.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping trigger for a ligation clamp, comprising:

[0006] The trigger body and the protrusion are integrally formed on the trigger body;

[0007] Anti-slip structure, located on the trigger body;

[0008] The anti-slip structure includes an anti-slip sleeve and a limiting ring. The anti-slip sleeve is fitted onto the outside of the trigger body, and the limiting ring is fixedly connected to the inside of the anti-slip sleeve. A limiting groove is provided on the outside of the trigger body, and the limiting ring is inserted into the inside of the limiting groove. A mesh groove is provided on the side of the anti-slip sleeve near the protrusion. A positioning slot is provided at the bottom of the trigger body, and a positioning block is inserted into the positioning slot. The bottom of the positioning block is fixedly connected to the inside of the anti-slip sleeve.

[0009] Preferably, the anti-slip sleeve, the limiting ring, and the positioning block are all made of rubber.

[0010] Preferably, the limiting ring and the limiting groove are internally interference-fitted, and the positioning block and the positioning slot are internally interference-fitted.

[0011] Preferably, a retainer is fixedly installed at the top of the trigger body, and a metal lever is fixedly connected to the side of the trigger body away from the protrusion.

[0012] Preferably, a rotating component is installed inside the trigger body.

[0013] Preferably, the trigger body has a finger grip groove on the side near the protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The clamping forceps trigger of this ligation clip, through the double interference fit of the limiting ring and the limiting groove and the positioning plug and the positioning slot, makes the anti-slip sleeve and the trigger body form a stable connection. Even when the high-frequency pinching operation or the application of large grip force is performed, the anti-slip sleeve will not move axially or twist circumferentially, avoiding grip failure caused by the displacement of the anti-slip structure, and providing continuous and stable anti-slip protection for surgical operation.

[0016] 2. The metal material of the ligation clip's application forceps trigger has higher hardness and strength compared to existing integrated triggers and plastic triggers. It can withstand greater force and is less prone to breakage, avoiding breakage due to insufficient trigger strength, which would prevent the application forceps from functioning properly. This helps reduce surgical costs and patient surgical risks. Attached Figure Description

[0027] Please see Figure 1-4 This utility model provides a technical solution: a clamping trigger for a ligation clip, comprising:

[0028] The trigger body 1 and the protrusion 8 are integrally formed on the trigger body 1.

[0029] Anti-slip structure, the anti-slip structure is located on the trigger body 1;

[0030] The anti-slip structure includes an anti-slip sleeve 5 and a limiting ring 12. The anti-slip sleeve 5 is fitted onto the outside of the trigger body 1, and the limiting ring 12 is fixedly connected to the inside of the anti-slip sleeve 5. A limiting groove 9 is provided on the outside of the trigger body 1, and the limiting ring 12 is inserted into the inside of the limiting groove 9. A mesh groove 7 is provided on the side of the anti-slip sleeve 5 near the protrusion 8. A positioning slot 10 is provided at the bottom of the trigger body 1, and a positioning plug 11 is inserted into the inside of the positioning slot 10. The bottom of the positioning plug 11 is fixedly connected to the inside of the anti-slip sleeve 5.

[0031] The anti-slip sleeve 5, the limiting ring 12 and the positioning block 11 are all made of rubber. The limiting ring 12 and the limiting groove 9 are internally interference fit, and the positioning block 11 and the positioning slot 10 are internally interference fit.

[0032] A latch 2 is fixedly installed at the top of the trigger body 1. A metal paddle 3 is fixedly connected to the side of the trigger body 1 away from the protrusion 8. A rotating part 4 is installed inside the trigger body 1. A finger grip groove 6 is provided on the side of the trigger body 1 near the protrusion 8.

[0033] Furthermore, when using this device, the anti-slip sleeve 5 is fixed by an interference fit between the limiting ring 12 and the limiting groove 9 on the outside of the trigger body 1. Simultaneously, the interference fit between the positioning block 11 and the positioning slot 10 prevents the anti-slip sleeve 5 from rotating circumferentially. This dual limiting design ensures that the anti-slip sleeve 5 does not loosen or shift during frequent operation, allowing it to remain stably in its initial position. When the doctor's finger grips the trigger, the mesh grooves 7 on the anti-slip sleeve 5 form multi-point contact with the finger skin, increasing the friction area. In humid environments, the mesh grooves 7 can also guide sweat flow, preventing the formation of a water film that reduces friction and ensuring stable grip.

[0034] Compared to existing integrated triggers and plastic triggers, the metal material of the metal trigger 3 has higher hardness and strength. During surgery, when doctors are accustomed to operating the clamps, the metal trigger 3 can withstand greater force and is less prone to breakage. This avoids breakage due to insufficient trigger strength, which would render the clamps unusable. This helps reduce surgical costs and patient risks. Surgical safety is the primary consideration, and the high strength of the metal trigger 3 provides more reliable protection for the surgical process, reducing unexpected situations caused by instrument malfunctions and allowing doctors to focus more on the surgical procedure.

[0035] Through the double interference fit between the limiting ring 12 and the limiting groove 9 and the positioning plug 11 and the positioning slot 10, the anti-slip sleeve 5 and the trigger body 1 form a stable connection. Even when the high-frequency pinching operation is performed or a large grip force is applied, the anti-slip sleeve 5 will not move axially or twist circumferentially, avoiding grip failure caused by the displacement of the anti-slip structure, and providing continuous and stable anti-slip protection for surgical operations.

[0036] Structural Description: Trigger Body 1: As the main structure of the clamping pliers trigger, it supports all functional components and provides the basic operating framework;

[0037] Protrusion 8: integrally formed with the trigger body 1, increasing the three-dimensional feel when holding the trigger, making it easier for the fingers to position and apply force;

[0038] Anti-slip sleeve 5: Fitted on the outside of the trigger body 1, the surface mesh groove 7 increases the friction with the fingers, improves grip stability, and the rubber material provides elastic cushioning;

[0039] Limiting ring 12: Fixed inside the anti-slip sleeve 5, and interference fits with the limiting groove 9 of the trigger body 1 to achieve axial fixation of the anti-slip sleeve 5;

[0040] Limiting groove 9: It is formed on the outside of the trigger body 1 and is inserted into the limiting ring 12 to restrict the movement of the anti-slip sleeve 5 along the trigger axis;

[0041] Mesh groove 7: Located on the side of the anti-slip sleeve 5 near the protrusion 8, the groove and protrusion structure increases the contact area, guides the flow of sweat, and enhances the anti-slip effect;

[0042] Positioning slot 10: It is located at the bottom of the trigger body 1 and is engaged with the positioning block 11 to prevent the anti-slip sleeve 5 from rotating circumferentially;

[0043] Positioning block 11: Fixed inside the anti-slip sleeve 5, inserted into the positioning slot 10, and together with the limiting ring 12 to form a double limit, ensuring the stability of the anti-slip sleeve 5;

[0044] Card holder 2: Fixed to the top of the trigger body 1, used to connect and fix with other parts of the clamping pliers to realize the linkage between the trigger and the clamp body;

[0045] Metal lever 3: Fixed to the side of the trigger body 1 away from the protrusion 8, it uses the elasticity of metal to reset the trigger and provide operating feedback force;

[0046] Rotating component 4: Installed inside the trigger body 1, serving as the axis of trigger rotation, allowing the trigger to rotate around it to achieve opening and closing actions;

[0047] Finger groove 6: Located on the side of the trigger body 1 near the protrusion 8, it conforms to the curvature of the fingers, optimizes the grip feel, and reduces operating fatigue.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
