[0024] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0025] An adjustable clamping force vascular occlusion clamp includes a first clamping body 1, a second clamping body 2, and a spring 3. The two ends of the spring 3 are respectively connected to the first clamping body 1 and the second clamping body 2. The first clamping body 1 includes a first clamping shell 11, a first clamping plate 12, an adjusting rod 13, and a rotary cover 14. The adjusting rod 13 is installed inside the first clamping shell 11. The rotary cover 14 is arranged correspondingly to the adjusting rod 13 and is used to rotate and drive the adjusting rod 13 to move in the axial direction. One end of the spring 3 is connected to the adjusting rod 13. The second clamping body 2 includes a second clamping shell 21 and a second clamping plate 22. The first clamping shell 11 and the second clamping shell 21 are movably embedded. The first clamping plate 12 and the second clamping plate 22 are arranged correspondingly and are in an open / closed separation state or a closed clamping state. The spring 3 is used to cause the first clamping plate 12 and the second clamping plate 22 to be in a closed clamping state.

[0026] In the aforementioned adjustable clamping force vascular occlusion clamp, the doctor uses surgical forceps to clamp the first clamping component 1 and the second clamping component 2, causing the first clamping component 1 and the second clamping component 2 to be in an open and closed state. When the target blood vessel is between the first clamping component 1 and the second clamping component 2, the doctor releases the surgical forceps. Under the action of the spring component 3, the first clamping component 1 and the second clamping component 2 are in a closed clamping state, thereby achieving vascular occlusion. In this way, the clamping force applied by the spring component 3 is more stable, effectively improving the reliability of the clamping force application. Furthermore, the adjustment rod 13 is driven by rotating the adjustment cover 14, thereby adjusting the compression stroke of the spring component 3 and controlling the clamping force of the first clamping component 1 and the second clamping component 2.

[0027] The aforementioned adjustable clamp force vascular occlusion clamp is for single use, reducing surgical time and the workload of doctors, avoiding the risk of cross-infection, and improving the safety of the surgery.

[0028] The first clamping member 1, the second clamping member 2, and the spring member 3 work together to create a strong clamping force between the first clamping member 1 and the second clamping member 2. This strong clamping force can firmly clamp the blood vessel, effectively control bleeding, or separate the blood vessel. Furthermore, the clamping force of the vascular occlusion clamp can be adjusted by rotating the cover 14 to better adapt to various blood vessel sizes and avoid damage to the blood vessel due to unsuitable clamping force.

[0029] The adjusting rod 13 has a rod inclined surface 131, and the rotary cover 14 has a cover protrusion 143. The cover protrusion 143 is arranged to protrude in the direction toward the adjusting rod 13. The cover protrusion 143 is arranged to abut against the rod inclined surface 131. The cover protrusion 143 is used to drive the adjusting rod 13 to move axially under the rotation of external force.

[0030] Thus, when it is necessary to adjust the compression stroke of the spring 3, the cover 14 is turned to move the cover protrusion 143. As the contact position between the cover protrusion 143 and the inclined surface 131 of the rod changes, the axial drive of the adjusting rod 13 is realized. The movement of the adjusting rod 13 realizes the adjustment of the compression stroke of the spring 3.

[0031] The adjusting rod 13 includes a rod seat 132 and a rod body 133. The inner end of the rod body 133 is connected to the rod seat 132, and the outer end of the rod body 133 extends vertically in a direction away from the rod seat 132. The rod seat 132 has a rod inclined surface 131, and a spring element 3 is embedded in the rod body 133. The spring element 3 is connected to the rod seat 132. In this way, the rod body 133 plays a role in positioning and reinforcing the spring element 3, and the spring element 3 has a large contact area with the rod seat 132, which improves the deformation stability of the spring element 3.

[0032] The first clamping shell 11 has a shell rail, and the rod seat 132 has a seat rail. The seat rail and the shell rail are respectively arranged to extend along the axial direction and are movably assembled. Under the cooperation of the seat rail and the shell rail, the movement stability of the seat rod is improved, and the movement of the rod seat 132 is effectively prevented from deviating, thereby improving the movement stability of the adjusting rod 13.

[0033] The rod holder 132 has a clearance area, and the second clamping shell 21 is arranged correspondingly to the clearance area; the rod holder 132 includes a seat block, the rod body 133 is arranged in a mating arrangement with the seat block, and the clearance area is arranged around the circumference of the seat block; in this way, under the action of the clearance area, when switching to the open / closed separation state, collision between the second clamping shell 21 and the adjusting rod 13 is avoided, which facilitates the switching of the vascular blocking clamp to the open / closed separation state.

[0034] The rotating cover 14 includes an outer rotating cover 141 and a bayonet seat 142. The outer ends of the outer rotating cover 141 and the bayonet seat 142 are assembled and form multiple stop grooves 144. Each stop groove 144 is arranged at intervals along the circumference. The first clamping shell 11 has a shell locking groove, which is arranged in a ring. The bayonet seat 142 is embedded in the shell locking groove. Under the action of the bayonet seat 142, the assembly of the outer rotating cover 141 is realized, which plays a positioning and limiting role for the outer rotating cover 141.

[0035] The first clamping shell 11 has a gear bar 111, which is arranged in a raised manner and is used to be embedded in the gear groove 144; in this way, the switching of different gears can be realized by the cooperation of the gear bar 111 and different gear grooves 144.

[0036] The outer cap 141 has a capping surface, which is arranged in a direction away from the bayonet seat 142. The capping surface includes a middle cap area and an outer cap area. The outer cap area surrounds the middle cap area. The middle cap area is arranged in a concave arc shape facing the bayonet seat 142. The outer cap area is provided with anti-slip texture. The middle cap area and the outer cap area are used for clamping with surgical forceps.

[0037] In this way, the combined action of the middle and outer cover areas provides an anti-slip effect, better fits the surgical forceps, and makes it easier to place the vascular occlusion clamp in the designated position, thus facilitating vascular occlusion procedures.

[0038] The second clamping component 2 includes an anti-slip cover 24, which is assembled with the second clamping shell 21. The anti-slip cover 24 and the outer rotating cover 141 are arranged at opposite ends. The anti-slip cover 24 and the outer rotating cover 141 are used for clamping with surgical forceps. The anti-slip cover 24 has an anti-slip surface, which is arranged in a direction away from the second clamping shell 21. The anti-slip surface includes a middle anti-slip area and an outer anti-slip area. The outer anti-slip area surrounds the middle anti-slip area and has anti-slip textures. The middle anti-slip area and the outer anti-slip area are used for clamping with surgical forceps.

[0039] In this way, the combined action of the middle and outer defense zones provides an anti-slip effect, better fits the surgical forceps, and makes it easier to place the vascular occlusion clamp in the designated position, thus facilitating vascular occlusion operations.

[0040] The first clamping shell 11 forms a first shell cavity inside, and the second clamping shell 21 includes a shell limiting part located in the first shell cavity. The first clamping shell 11 has a detachment limiting part arranged in a mating manner with the shell limiting part. The detachment limiting part is used to restrict the shell limiting part from detaching from the first shell cavity. In this way, the shell limiting part is effectively prevented from detaching from the first shell cavity, ensuring the assembly between the first clamping shell 11 and the second clamping shell 21.

[0041] The first clamping component 1 includes a first plate pad 15, which is assembled with the first clamping plate 12 in a flat arrangement. The second clamping component 2 includes a second plate pad 23, which is assembled with the second clamping plate 22 in a flat arrangement. The first plate pad 15 and the second plate pad 23 are in an open / closed separation state or a closed clamping state.

[0042] In this way, with the action of the first pad 15 and the second pad 23, it is easy to clamp the target blood vessel and achieve vascular occlusion.

[0043] The first plate pad 15 and the second plate pad 23 are respectively provided with pad teeth, which improve the clamping stability of the first plate pad 15 and the second plate pad 23 under the action of the pad teeth.

[0044] The first splint 12, the first pad 15, the second splint 22, and the second pad 23 are arranged in an arc shape to facilitate the doctor's clamping operation.

[0045] The first clamping shell 11 and the second clamping shell 21 are made of engineering plastics, making them lighter, easier to use, and easier for doctors to clamp and transfer with surgical forceps.

[0046] The first clip shell 11 is provided with a loop 4, which facilitates the removal of the suture when the vascular occlusion clip is removed.

[0047] When removing the vascular occlusion clip, the first clip body 1 and the second clip body 2 are clamped by surgical forceps, so that the first clip body 1 and the second clip body 2 switch from the closed clamping state to the open and closed separation state, thereby releasing the blood vessel and removing the vascular occlusion clip.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
