[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Reference below Figure 1-Figure 5 A clamp applier 100 according to an embodiment of the utility model is described, comprising: a housing 10; a spring piece 20, which is fixedly mounted on the housing 10; a trigger 30, which has an initial position, a clamping position and a clamping position relative to the housing 10, and the trigger 30 is rotatably mounted on the housing 10 so that the trigger 30 is rotated to one of the initial position, the clamping position and the clamping position, and along the rotation direction of the trigger 30, the clamping position is located between the initial position and the clamping position, and the spring piece 20 is located on a side of the trigger 30 away from the initial position, and when the trigger 30 is rotated from the initial position to the clamping position, the trigger 30 abuts against the spring piece 20.

[0034] Among them, at least one end of the spring piece 20 can be fixed to the housing 10. The present application takes the example that both opposite ends of the spring piece 20 are fixed to the housing 10. For example, the spring piece 20 and the housing 10 can be connected by welding, or by bolts, but the present invention is not limited thereto. The spring piece 20 and the housing 10 can also be connected by other means, as long as the spring piece 20 is fixed to the housing 10.

[0035] The trigger 30 has an initial position, a clamping position and a clamping position relative to the housing 10. Figure 1 The initial position of the trigger 30 is shown. Figure 2 The trigger 30 is shown in the clip delivery position. Figure 3 The trigger 30 is shown in the clamping position. The trigger 30 is rotatably disposed on the housing 10. For example, the trigger 30 and the housing 10 may be connected by a rotating shaft, a bearing, a screw, etc., but the present invention is not limited thereto. The trigger 30 and the housing 10 may also be connected by other structures, as long as the trigger 30 is rotatably disposed on the housing 10. Thus, the trigger 30 is rotatably disposed on the housing 10 so that the trigger 30 can be rotated to one of the initial position, the clamping position, and the clamping position.

[0036] Along the rotation direction of the trigger 30, the clip delivery position is located between the initial position and the clamping position, and the spring sheet 20 is located on the side of the trigger 30 away from the initial position. When the trigger 30 rotates from the initial position to the clip delivery position, the trigger 30 abuts against the spring sheet 20, so that the trigger 30 is subjected to a reaction force along the rotation direction of the trigger 30, thereby reminding the user of the force, so that the user stops pressing the trigger 30 at the clip delivery position in time, so as to accurately deliver the ligation clip to the tissue site of the operation, thereby improving the success rate and efficiency of the operation, and avoiding the clip applier 100 from continuously sending the ligation clip, thereby avoiding wasting the ligation clip, thereby improving the success rate and efficiency of the operation.

[0037] According to the clip applier 100 of the embodiment of the utility model, a spring sheet 20 is provided on the housing 10, and the spring sheet 20 is located on the side of the trigger 30 away from the initial position. When the trigger 30 rotates from the initial position to the clip delivery position, the trigger 30 abuts against the spring sheet 20, so that the trigger 30 is subjected to a reaction force along the rotation direction of the trigger 30, thereby providing a force reminder to the user, so that the user stops pressing the trigger 30 in the clip delivery position in time, which is convenient for accurately delivering the ligation clip to the tissue site of the operation, thereby improving the success rate and efficiency of the operation, and also avoiding the clip applier 100 from continuously sending the ligation clip, thereby avoiding wasting the ligation clip, thereby improving the success rate and efficiency of the operation.

[0038] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, during the rotation of the trigger 30 from the clamping position to the clamping position, the trigger 30 drives the spring 20 to deform elastically.

[0039] In the process of the trigger 30 rotating from the clip delivery position to the clamping position, the trigger 30 drives the spring sheet 20 to elastically deform. During the elastic deformation of the spring sheet 20, the trigger 30 can continue to rotate from the clip delivery position to the clamping position until the clamping is completed. In this process, since the trigger 30 drives the spring sheet 20 to elastically deform, the trigger 30 can be subjected to a reaction force along the direction of rotation of the trigger 30, thereby reminding the user of the force. When the elastic deformation of the spring sheet 20 reaches the upper limit, the trigger 30 cannot continue to rotate, that is, the clamping is completed, so that the user can distinguish the stroke of the clip applier 100, thereby avoiding user operation errors, thereby improving the success rate and efficiency of the operation.

[0040] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the spring piece 20 may include: a first fixing portion 21, a deformation portion 22 and a second fixing portion 23, the deformation portion 22 is connected between the first fixing portion 21 and the second fixing portion 23, the first fixing portion 21 and the second fixing portion 23 are both fixed to the housing 10, and the deformation portion 22 is suitable for abutting against the trigger 30.

[0041] Among them, the deformation part 22 is connected between the first fixing part 21 and the second fixing part 23. For example, the deformation part 22 and the first fixing part 21 and the second fixing part 23 can be integrally formed, or the deformation part 22 and the first fixing part 21 and the second fixing part 23 can be adhesively connected, but the utility model is not limited to this. The deformation part 22 and the first fixing part 21 and the second fixing part 23 can also be connected in other ways, as long as the deformation part 22 is connected between the first fixing part 21 and the second fixing part 23.

[0042] The first fixing portion 21 and the second fixing portion 23 are both fixedly disposed on the housing 10. For example, the housing 10 and the first fixing portion 21 and the second fixing portion 23 can be fixedly connected by snapping, or the housing 10 and the first fixing portion 21 and the second fixing portion 23 can be fixedly connected by bolts. However, the present invention is not limited thereto. The housing 10 and the first fixing portion 21 and the second fixing portion 23 can also be fixedly connected by other means, as long as the first fixing portion 21 and the second fixing portion 23 are both fixedly disposed on the housing 10.

[0043] The deformation portion 22 is suitable for abutting against the trigger 30. The elastic force of the deformation portion 22 is used to remind the user of the force, so that the user can stop pressing the trigger 30 in time at the clip delivery position, which is convenient for accurately delivering the ligation clip to the surgical tissue site, thereby improving the success rate and efficiency of the operation, and avoiding the clip applier 100 from continuously sending the ligation clip, thereby avoiding the waste of ligation clips, thereby improving the success rate and efficiency of the operation.

[0044] According to some embodiments of the present invention, Figure 4 As shown, the deformable portion 22 is formed with a protrusion 221 protruding toward the trigger 30 , and the protrusion 221 is suitable for abutting against the trigger 30 .

[0045] Among them, the deformation part 22 can be formed with a protrusion 221 protruding toward the trigger 30, and the protrusion 221 is suitable for abutting against the trigger 30, which can ensure that the deformation part 22 and the trigger 30 are reliably abutted, thereby ensuring that the deformation part 22 and the trigger 30 produce an elastic force on the trigger 30 after the abutment, and then remind the user of the force, so that the user can stop pressing the trigger 30 in the clamping position in time.

[0046] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the protrusion 221 includes a first supporting wall 222, an abutting wall 223 and a second supporting wall 224. The first supporting wall 222 and the second supporting wall 224 are opposite and spaced apart. The abutting wall 223 is connected between the first supporting wall 222 and the second supporting wall 224. The abutting wall 223 is constructed to be arc-shaped and protrudes toward the trigger 30. The abutting wall 223 is suitable for abutting against the trigger 30.

[0047] Among them, the first support wall 222 and the second support wall 224 are arranged opposite to each other and spaced apart, and the abutment wall 223 is connected between the first support wall 222 and the second support wall 224.

The first support wall 222 and the second support wall 224 can also be connected in other ways, as long as the abutment wall 223 is connected between the first support wall 222 and the second support wall 224.

[0048] The abutment wall 223 can be constructed in an arc shape and protrude toward the trigger 30, which can increase the abutment area between the abutment wall 223 and the trigger 30, thereby facilitating the reliable abutment between the abutment wall 223 and the trigger 30. In addition, constructing the abutment wall 223 in an arc shape can also improve the bearing capacity of the abutment wall 223, thereby improving the abutment reliability between the spring piece 20 and the trigger 30. When the trigger 30 is rotated to the clamping position, the user can feel the operating resistance, thereby improving the reliability and safety of the clip applier 100.

[0049] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the abutment wall 223 can be constructed in an arc shape, which can increase the abutment area between the abutment wall 223 and the trigger 30, thereby facilitating the reliable abutment between the abutment wall 223 and the trigger 30, and constructing the abutment wall 223 in an arc shape can also improve the bearing capacity of the abutment wall 223, thereby further improving the abutment reliability between the spring piece 20 and the trigger 30.

[0052] Furthermore, the housing 10 may also be formed with a first insertion port, which is connected to the first installation space 11 , and the first fixing portion 21 may be assembled in the first installation space 11 through the first insertion port, thereby achieving the effect of assembling the first fixing portion 21 in the first installation space 11 .
