[0038] Reference below Figure 1-Figure 5 The clip applier 100 according to the embodiment of the utility model comprises: a housing 10; a spring sheet 20, which is rotatably arranged on the housing 10; a trigger 30, which has an initial position, a clip delivery position and a clipping position relative to the housing 10, and the trigger 30 is rotatably arranged on the housing 10 so that the trigger 30 is rotated to one of the initial position, the clip delivery position and the clipping position, and the clip delivery position is located between the initial position and the clipping position along the rotation direction of the trigger 30, and the rotation axis of the spring sheet 20 and the trigger 30 are 0 is parallel to the rotation axis of the trigger 30; the stop rod 31 is arranged on the trigger 30, and the stop rod 31 is suitable for abutting against the spring piece 20 to deform the spring piece 20 during the rotation of the trigger 30 from the initial position to the clamping position, and when the trigger 30 is rotated to the clamping position, the stop rod 31 is separated from the spring piece 20 to make the spring piece 20 vibrate and make a sound; when the trigger 30 is rotated from the clamping position to the initial position, the stop rod 31 is suitable for abutting against the spring piece 20 to drive the spring piece 20 to rotate, so that the spring piece 20 avoids the stop rod 31.

[0039] Among them, the spring clip 20 can be constructed as a steel part or a beryllium copper part. This application takes the spring clip 20 constructed as a beryllium copper part as an example for explanation. The beryllium copper material has a high stiffness limit and a high elastic limit, which can improve the strength and elastic deformation performance of the spring clip 20, thereby improving the performance and service life of the spring clip 20.

[0040] The spring piece 20 is rotatably disposed on the housing 10. For example, the spring piece 20 and the housing 10 may be connected via a pivot shaft, or the spring piece 20 and the housing 10 may be connected via a hinge. However, the present invention is not limited thereto. The spring piece 20 and the housing 10 may be connected in other ways as long as the spring piece 20 is rotatably disposed on the housing 10. The trigger 30 has an initial position, a clamping position, and a clamping position relative to the housing 10. Figure 1 The trigger 30 is shown in an initial position. Figure 2 The trigger 30 is shown in the clip delivery position. Figure 3The trigger 30 is shown in the clamping position, and the clamping delivery position is located between the initial position and the clamping position along the rotation direction of the trigger 30. The trigger 30 is rotatably disposed on the housing 10. For example, the trigger 30 and the housing 10 can be connected by a rotating shaft, a bearing, a screw, etc., but the utility model is not limited thereto. The trigger 30 and the housing 10 can also be connected by other structures, as long as the trigger 30 is rotatably disposed on the housing 10. Therefore, 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 delivery position and the clamping position.

[0041] The stop rod 31 is provided on the trigger 30, for example, the stop rod 31 and the trigger 30 can be connected by a snap connection, or the stop rod 31 can be movably provided on the trigger 30, but the utility model is not limited thereto, and the stop rod 31 and the trigger 30 can also be connected by other means, as long as the stop rod 31 is provided on the trigger 30. During the rotation of the trigger 30 from the initial position to the clip delivery position, the stop rod 31 is adapted to abut against the spring sheet 20 to deform the spring sheet 20, and when the trigger 30 rotates to the clip delivery position, the stop rod 31 is separated from the spring sheet 20 to make the spring sheet 20 vibrate and make a sound, so that the user stops pressing the trigger 30 in time at the clip delivery position, 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 also avoiding the clip applier 100 from continuously delivering the ligation clip, thereby avoiding the waste of the ligation clip.

[0042] The rotation axis of the spring sheet 20 and the rotation axis of the trigger 30 can be parallel. During the rotation of the trigger 30 from the clamping position to the initial position, the stop rod 31 is suitable for abutting against the spring sheet 20 to drive the spring sheet 20 to rotate, so that the spring sheet 20 avoids the stop rod 31, thereby allowing the trigger 30 to rotate smoothly to the initial position, and then allowing the clip applier 100 to perform the next clamping operation. Such a cyclic operation can improve the clamping accuracy and efficiency of the clip applier 100, thereby improving the success rate and efficiency of the operation, avoiding the clip applier from continuously sending ligation clips, and thus avoiding wasting ligation clips.

[0043] According to the clip applier 100 of the embodiment of the utility model, the stop rod 31 is suitable for abutting against the spring sheet 20 to deform the spring sheet 20 during the process of the trigger 30 rotating from the initial position to the clip delivery position, and when the trigger 30 rotates to the clip delivery position, the stop rod 31 is separated from the spring sheet 20 to make the spring sheet 20 vibrate and make a sound, so that the clip applier 100 can give an obvious prompt when delivering the clip to the clamp head, so that the user can stop 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, avoiding the clip applier 100 from continuously sending the ligation clip, and thus avoiding wasting the ligation clip.

[0044] According to some embodiments of the present invention, Figure 2As shown, the housing 10 may be formed with a support portion 11, which is located on a side of the spring sheet 20 away from the trigger 30. When the trigger 30 rotates from the initial position to the clamping position, the support portion 11 supports the spring sheet 20 to limit the rotation of the spring sheet 20.

[0045] The housing 10 may be formed with a support portion 11, for example, the housing 10 and the support portion 11 may be integrally formed, and the housing 10 and the support portion 11 may be connected by welding, but the present invention is not limited thereto, and the housing 10 and the support portion 11 may be connected by other means, as long as the housing 10 is formed with the support portion 11. The support portion 11 may be located on the side of the spring sheet 20 away from the trigger 30, and during the rotation of the trigger 30 from the initial position to the clip delivery position, the support portion 11 supports the spring sheet 20 to limit the rotation of the spring sheet 20, so that the stop rod 31 abuts against the spring sheet 20 to deform the spring sheet 20, and when the trigger 30 rotates to the clip delivery position, the stop rod 31 separates from the spring sheet 20 to make the spring sheet 20 vibrate and sound, thereby prompting the user to stop pressing the trigger 30 at the clip delivery position, so as to facilitate the accurate delivery of the ligation clip to the tissue site of the operation, thereby further improving the success rate and efficiency of the operation, and further avoiding the clip applier 100 from continuously sending the ligation clip, thereby further avoiding the waste of the ligation clip.

[0046] According to some embodiments of the present invention, Figure 2 As shown, the spring piece 20 may have an abutment portion 21 and a limiting portion 22, which are respectively located at two ends of the spring piece 20, the abutment portion 21 is suitable for abutting against the stop rod 31, and the limiting portion 22 is suitable for abutting against the support portion 11 so that the support portion 11 supports the spring piece 20.

[0047] The spring sheet 20 may include an abutment portion 21 and a limiting portion 22, which are respectively located at opposite ends of the spring sheet 20. The abutment portion 21 may be located at one end of the spring sheet 20 close to the trigger 30, so as to facilitate the abutment portion 21 and the stop rod 31. Thus, when the trigger 30 rotates from the initial position to the clamping position, the limiting portion 22 abuts against the support portion 11, so that the support portion 11 supports the spring sheet 20 to limit the rotation of the spring sheet 20, and the abutment portion 21 abuts against the stop rod 31 to deform the spring sheet 20.

[0048] According to some embodiments of the present invention, Figure 2 As shown, the spring piece 20 can also have a spring piece body 23 and a mounting ear 24, and the opposite ends of the spring piece body 23 are respectively connected to the abutment portion 21 and the limiting portion 22, so that the spring piece body 23 is connected between the abutment portion 21 and the limiting portion 22, the spring piece body 23 and the mounting ear 24 are fixedly connected, and the mounting ear 24 and the housing 10 are pivotally connected.

[0049] Among them, the spring piece 20 can also have a spring piece body 23 and a mounting ear 24, and the opposite ends of the spring piece body 23 are respectively connected to the abutment portion 21 and the limiting portion 22, so that the spring piece body 23 is connected between the abutment portion 21 and the limiting portion 22. For example, the spring piece body 23, the abutment portion 21, and the limiting portion 22 can be integrally formed, or the spring piece body 23, the abutment portion 21, and the limiting portion 22 can be adhesively connected, but the utility model is not limited to this. The spring piece body 23, the abutment portion 21, and the limiting portion 22 can also be connected in other ways, as long as the opposite ends of the spring piece body 23 are respectively connected to the abutment portion 21 and the limiting portion 22.

[0050] The spring sheet body 23 and the mounting ear 24 are fixedly connected, for example, the spring sheet body 23 and the mounting ear 24 can be integrally formed, or the spring sheet body 23 and the mounting ear 24 can be adhesively connected, but the utility model is not limited thereto, the spring sheet body 23 and the mounting ear 24 can also be fixedly connected by other means, as long as the spring sheet body 23 and the mounting ear 24 are fixedly connected. The mounting ear 24 and the housing 10 are pivotally connected, for example, the mounting ear 24 and the housing 10 can be pivotally connected by a rotating shaft, a bearing, a screw or other structure, but the utility model is not limited thereto, the mounting ear 24 and the housing 10 can also be pivotally connected by other structures, as long as the mounting ear 24 and the housing 10 are pivotally connected.

[0051] Thus, the spring sheet 20 can be rotatably arranged on the housing 10. During the process of the trigger 30 rotating from the clamping position to the initial position, the stop rod 31 is suitable for abutting against the spring sheet 20 to drive the spring sheet 20 to rotate, so that the spring sheet 20 avoids the stop rod 31, thereby allowing the trigger 30 to rotate smoothly to the initial position, and then allowing the clip applier 100 to perform the next clamping operation. Such a cyclic operation can improve the clamping accuracy and efficiency of the clip applier 100, thereby improving the success rate and efficiency of the operation.

[0052] According to some embodiments of the present invention, there may be two mounting ears 24, which are respectively disposed on opposite side edges of the spring body 23, each mounting ear 24 is formed with a pivot hole 241, and the pivot holes 241 of the two mounting ears 24 are opposite to each other.

[0053] There may be two mounting ears 24, which are respectively arranged on the opposite side edges of the spring body 23, each mounting ear 24 is formed with a pivot hole 241, and the pivot holes 241 of the two mounting ears 24 can be arranged relative to each other so that the pivot structure passes through the pivot holes 241 of the two mounting ears 24 at the same time, thereby the spring 20 can be rotatably assembled on the housing 10.

[0054] According to some embodiments of the present invention, Figure 2As shown, the spring body 23 may be formed with an arc segment 26 , the abutting portion 21 is configured as an arc, the arc segment 26 is adjacent to the abutting portion 21 , and the arc segment 26 protrudes toward one side of the spring body 23 , and the abutting portion 21 protrudes toward the other side of the spring body 23 .

[0055] Among them, the spring sheet body 23 can be formed with an arc segment 26, the abutment portion 21 is constructed as an arc, the arc segment 26 is adjacent to the abutment portion 21, and the arc segment 26 protrudes toward one side of the spring sheet body 23, and the abutment portion 21 protrudes toward the other side of the spring sheet body 23. Specifically, the arc segment 26 can protrude toward the side of the spring sheet body 23 close to the trigger 30, and the abutment portion 21 protrudes toward the side of the spring sheet body 23 away from the trigger 30. In this way, when the trigger 30 rotates from the initial position to the clamping position, the stop rod 31 of the trigger 30 can abut against the protruding surface of the abutment portion 21 to allow the spring sheet 20 to deform smoothly, and the arc segment 26 is adjacent to the abutment portion 21, which can reduce the deformation of the spring sheet 20, thereby reducing the space occupied by the spring sheet 20 in the housing 10, thereby reducing the volume and manufacturing cost of the clamp applier 100.

[0056] According to some embodiments of the present invention, Figure 2 As shown, the clip applier 100 may further include a reset drive member 14 . When the stop rod 31 drives the spring sheet 20 to rotate so that the spring sheet 20 avoids the stop rod 31 , the reset drive member 14 drives the spring sheet 20 to reset.

[0057] The clip applier 100 may further include a reset drive 14, which may be a drive such as an elastic member, a linear motor, or a cylinder, and is not specifically limited here, as long as the reset drive 14 can drive the spring sheet 20 to reset. When the stop rod 31 drives the spring sheet 20 to rotate so that the spring sheet 20 avoids the stop rod 31, that is, when the spring sheet 20 and the stop rod 31 are separated, the reset drive 14 can drive the spring sheet 20 to reset, so that the clip applier 100 can perform the next clamping operation. Such a cyclic operation can improve the clamping accuracy and efficiency of the clip applier 100, thereby improving the success rate and efficiency of the operation.

[0058] According to some embodiments of the present invention, Figure 2 As shown, the reset drive member 14 can be constructed as an elastic member, and the housing 10 can be formed with a first limiting wall 12 opposite to and spaced apart from the spring sheet 20. The reset drive member 14 and the first limiting wall 12 are both located on the side of the spring sheet 20 facing the trigger 30, and the elastic member is located between the first limiting wall 12 and the spring sheet 20, one end of the elastic member is connected to the first limiting wall 12, and the other end of the elastic member abuts against the spring sheet 20.

[0059] The reset driving member 14 may be configured as an elastic member, and the elastic member may be a spring. The housing 10 may be formed with a first limiting wall 12 opposite to and spaced from the spring sheet 20, for example, the housing 10 and the first limiting wall 12 may be integrally formed, or the housing 10 and the first limiting wall 12 may be welded, but the utility model is not limited thereto, and the housing 10 and the first limiting wall 12 may also be connected in other ways, as long as the housing 10 is formed with a first limiting wall 12 opposite to and spaced from the spring sheet 20.

[0060] The reset drive member 14 and the first limiting wall 12 can both be located on the side of the spring sheet 20 facing the trigger 30, and the elastic member is located between the first limiting wall 12 and the spring sheet 20, and one end of the elastic member is connected to the first limiting wall 12, for example, the elastic member and the first limiting wall 12 can be connected by a snap connection, or the elastic member and the first limiting wall 12 can be connected by an adhesive, but the utility model is not limited thereto, and the elastic member and the first limiting wall 12 can also be connected by other means, as long as one end of the elastic member is connected to the first limiting wall 12. The other end of the elastic member abuts against the spring sheet 20, for example, the elastic member and the spring sheet 20 can be connected by a snap connection, or the elastic member and the spring sheet 20 can be connected by an adhesive, but the utility model is not limited thereto, and the elastic member and the spring sheet 20 can also be connected by other means, as long as one end of the elastic member is connected to the spring sheet 20.

[0061] Thus, one end of the elastic member is connected to the first limiting wall 12, and the other end of the elastic member abuts against the spring sheet 20. Specifically, when the trigger 30 rotates from the initial position to the clip delivery position, the spring sheet 20 abuts against the stop rod 31 to deform, and the stop rod 31 separates from the spring sheet 20 to make the spring sheet 20 vibrate and make a sound, so that the user stops pressing the trigger 30 in time at the clip delivery position.

[0062] When the clip applier 100 is clamped, the trigger 30 rotates from the clamped position to the initial position, and the stop rod 31 drives the spring sheet 20 to rotate. During the rotation of the spring sheet 20, the limit portion 22 of the spring sheet 20 rotates toward the reset drive member 14, so that the limit portion 22 compresses and deforms the reset drive member 14. When the spring sheet 20 continues to rotate and separates from the stop rod 31, the reset drive member 14 can return to its original position under the action of its own elastic force, and then can drive the spring sheet 20 to reset, so that the trigger 30 can smoothly rotate from the clamped position to the initial position. Then, the clip applier 100 can perform the next clamping operation. Such a cyclic operation can further improve the clamping accuracy and efficiency of the clip applier 100, and further improve the success rate and efficiency of the operation.

[0063] According to some embodiments of the present invention, Figure 2As shown, the housing 10 may be formed with a mounting groove 13 , the bottom wall of the mounting groove 13 is configured as a first limiting wall 12 , and one end of the elastic member is assembled in the mounting groove 13 .

[0064] Among them, the shell 10 can form an installation groove 13, and the installation groove 13 is arranged corresponding to the elastic member. The bottom wall of the installation groove 13 is constructed as a first limiting wall 12, so that one end of the elastic member can be assembled in the installation groove 13, so that the installation groove 13 can play a limiting support role for the elastic member, preventing the elastic member from detaching from the shell 10, thereby improving the safety and reliability of the clip applier 100.

[0065] According to some embodiments of the present invention, Figure 2 As shown, the spring sheet 20 may be formed with a second limiting wall 25 bent toward the elastic member, and the elastic member is sleeved on the second limiting wall 25 .

[0066] The spring sheet 20 may be formed with a second limiting wall 25 bent toward the elastic member, and the second limiting wall 25 is arranged corresponding to the elastic member, so that the elastic member is sleeved on the second limiting wall 25, so that one end of the elastic member is connected to the spring sheet 20, and then the elastic force of the reset driving member 14 can drive the spring sheet 20 to reset, so that the clip applier 100 can perform the next clamping operation, and such a cyclic operation can further improve the clamping accuracy and efficiency of the clip applier 100, and further improve the success rate and efficiency of the operation. In addition, the second limiting wall 25 and the reset driving member 14 are limited and matched, so that the reset driving member 14 can be prevented from deflecting.

[0067] According to some embodiments of the present invention, the clip applier 100 may further include: a stop rod 40, the top of the stop rod 40 is pivotally connected to the housing 10, the rotation axis of the stop rod 40 is parallel to the rotation axis of the trigger 30, the bottom of the stop rod 40 is movably connected to the housing 10, the stop rod 40 is located between the trigger 30 and the spring 20, the stop rod 31 extends toward the stop rod 40 to extend the trigger 30, and the stop rod 31 is movably arranged on the trigger 30 so that the stop rod 31 is moved toward Or moves away from the housing 10; during the rotation of the trigger 30 from the initial position to the clamping position, the stop rod 31 abuts against the stop rod 40 and moves along the stop rod 40 toward the top of the stop rod 40 to drive the stop rod 40 to rotate in the direction away from the trigger 30; during the rotation of the trigger 30 from the clamping position to the initial position, the stop rod 31 abuts against the stop rod 40 and moves along the stop rod 40 toward the bottom of the stop rod 40 to drive the stop rod 40 to rotate toward the trigger 30.

[0068] The top of the stop rod 40 is pivotally connected to the housing 10. For example, the stop rod 40 and the housing 10 may be pivotally connected via a rotating shaft, a bearing or the like, but the present invention is not limited thereto. The stop rod 40 and the housing 10 may also be pivotally connected via other structures, as long as the stop rod 40 and the housing 10 are pivotally connected. The rotation axis of the stop rod 40 and the rotation axis of the trigger 30 may be parallel, and the bottom of the stop rod 40 is movably connected to the housing 10 so that the stop rod 40 and the trigger 30 rotate in the same direction. The stop rod 40 is located between the trigger 30 and the spring 20, and the stop rod 31 extends out of the trigger 30 toward the stop rod 40. The stop rod 31 and the trigger 30 may be connected via an elastic member so that the stop rod 31 is movably arranged on the trigger 30 so that the stop rod 31 moves toward or away from the housing 10.

[0069] The top of the stop rod 40 may be an end close to the spring sheet 20, and the bottom of the stop rod 40 may be an end away from the spring sheet 20. It can be explained that, during the process of the trigger 30 rotating from the initial position to the clamping position and the process of the trigger 30 rotating from the clamping position to the initial position, the abutting surfaces of the stop rod 31 and the stop rod 40 may be different. Thus, during the process of the trigger 30 rotating from the initial position to the clamping position, the stop rod 31 abuts against the stop rod 40 and moves along the stop rod 40 toward the top of the stop rod 40, so as to drive the stop rod 40 to rotate in the direction away from the trigger 30. During the rotation of the trigger 30 from the clamping position to the initial position, the stop rod 31 abuts against the stop rod 40 and moves along the stop rod 40 toward the bottom of the stop rod 40 to drive the stop rod 40 to rotate toward the trigger 30, thereby limiting the moving stroke of the stop rod 31 and the stop rod 40, avoiding irregular movement of the stop rod 31 and the stop rod 40, and thereby improving the safety and reliability of the clamp applier 100.

[0070] According to some embodiments of the present invention, the clamp applier 100 may further include: an elastic driving member 15, a trigger 30 formed with an assembly groove 32, one end of the stop rod 31 extends into the assembly groove 32, the elastic driving member 15 is located in the assembly groove 32 and is connected between the bottom wall of the assembly groove 32 and the stop rod 31, a surface of the stop rod 40 facing the trigger 30 is formed with a first abutting surface 41, and a surface of the stop rod 40 facing the spring sheet 20 is formed with a second abutting surface 42, when the trigger 30 rotates from the initial position to the clamping position, the stop rod 31 abuts against the first abutting surface 41, and when the trigger 30 rotates from the clamping position to the initial position, the stop rod 31 abuts against the second abutting surface 42.

[0071] The trigger 30 may be formed with an assembly groove 32, one end of the stop rod 31 extends into the assembly groove 32, and the elastic driving member 15 is located in the assembly groove 32 and connected between the bottom wall of the assembly groove 32 and the stop rod 31. For example, the elastic driving member 15 and the assembly groove 32 and the stop rod 31 may be connected by snapping, or the elastic driving member 15 and the assembly groove 32 and the stop rod 31 may be connected by bonding, but the utility model is not limited thereto. The elastic driving member 15 and the assembly groove 32 and the stop rod 31 may be connected by other means, as long as the elastic driving member 15 is located in the assembly groove 32 and connected between the bottom wall of the assembly groove 32 and the stop rod 31. The stop rod 31 can be driven to move away from the housing 10 by the elastic driving member 15.

[0072] A first abutting surface 41 may be formed on the surface of the stop rod 40 facing the trigger 30, and a second abutting surface 42 may be formed on the surface of the stop rod 40 facing the spring sheet 20. During the process of the trigger 30 rotating from the initial position to the clamping position, the stop rod 31 abuts against the first abutting surface 41 and moves along the stop rod 40 toward the top of the stop rod 40 to drive the stop rod 40 to rotate away from the trigger 30. During the process of the trigger 30 rotating from the clamping position to the initial position, the stop rod 31 abuts against the second abutting surface 42 and moves along the stop rod 40 toward the bottom of the stop rod 40 to drive the stop rod 40 to rotate toward the trigger 30, thereby further limiting the moving stroke of the stop rod 31 and the stop rod 40, further avoiding irregular movement of the stop rod 31 and the stop rod 40, and further improving the safety and reliability of the clamp applier 100.

[0073] According to some embodiments of the present invention, Figure 2 As shown, the first abutment surface 41 can be formed with a plurality of limiting teeth 411, and the plurality of limiting teeth 411 are arranged in sequence along the height direction of the stop rod 40, and two adjacent limiting teeth 411 are spaced apart to form a limiting groove 412 between the two adjacent limiting teeth 411, and a portion of the stop rod 31 is suitable for extending into the limiting groove 412. When the trigger 30 rotates from the initial position to the clamping position, the stop rod 31 extends into the limiting groove 412 at the top end.

[0074] Among them, the first abutting surface 41 can be formed with a plurality of limiting teeth 411. For example, the first abutting surface 41 can be formed with two, three, four or the like limiting teeth 411, but the utility model is not limited to this. The first abutting surface 41 can also be formed with other numbers of limiting teeth 411. As long as the first abutting surface 41 is formed with a plurality of limiting teeth 411, no specific limitation is made here. The number of limiting teeth 411 can be set and adjusted according to actual conditions, as long as it can meet the normal operation of the clamp applier 100.

[0075] Multiple limit teeth 411 can be arranged in sequence along the height direction of the stop rod 40, and two adjacent limit teeth 411 are spaced apart to form a limit groove 412 between the two adjacent limit teeth 411. Part of the stop rod 31 is suitable for extending into the limit groove 412. During the rotation of the trigger 30 from the initial position to the clamp delivery position, the stop rod 31 will produce a jam when moving along the stop rod 40 in the multiple limit grooves 412. When the trigger 30 rotates from the initial position to the clamp delivery position, the stop rod 31 extends into the limit groove 412 at the top end, and then stops jamming to prompt the user that the clamp applier 100 has reached the clamp delivery position.

[0076] According to some embodiments of the present invention, Figure 2 As shown, the second abutting surface 42 can be configured as an arc-shaped surface convex toward the elastic sheet 20 .

[0077] Among them, when the trigger 30 rotates from the clamping position to the initial position, the stop rod 31 abuts against the second abutment surface 42, and the second abutment surface 42 is constructed as an arc-shaped surface protruding toward the spring piece 20, which can enable the stop rod 31 to quickly move from the second abutment surface 42 to the bottom of the shift rod, thereby enabling the trigger 30 to quickly rotate from the clamping position to the initial position, thereby improving the resetting speed of the clamp applier 100 and thereby improving the efficiency of the operation.

[0078] According to some embodiments of the present invention, Figure 2 As shown, the bottom of the stop rod 40 may be formed with an elongated limiting hole 43, and the housing 10 may be formed with a limiting column 16. For example, the housing 10 and the limiting column 16 may be integrally formed, or the housing 10 and the limiting column 16 may be welded, but the utility model is not limited thereto, and the housing 10 and the limiting column 16 may be connected in other ways, as long as the housing 10 forms the limiting column 16. The limiting column 16 is penetrated through the limiting hole 43, so that the housing 10 has a limiting effect on the stop rod 40, and prevents the bottom of the stop rod 40 from swinging in the housing 10, and the elongated limiting hole 43 can leave a certain moving space for the stop rod 40, and prevent the stop rod 31 from being stuck with the stop rod 40, so that the stop rod 31 can move smoothly along the stop rod 40.

[0079] According to some embodiments of the present invention, the clip applier 100 may further include: a driving structure, for example: the driving structure may be a motor, a cylinder, an elastic member, etc., but the present invention is not limited thereto, and the driving structure may also be other structures, as long as the driving structure can be used to drive the trigger 30 to reset. Thus, when the trigger 30 rotates from the initial position to the clamping position and the clamping operation is completed, the driving structure can drive the trigger 30 to reset, thereby allowing the clip applier 100 to perform the next clamping operation, thereby improving the efficiency and success rate of the operation.

[0080] Specifically, when the trigger 30 rotates from the initial position to the clip delivery position, the stop rod 31 moves toward the top of the stop rod 40 along the multiple limiting grooves 412 of the first abutting surface 41, and due to the abutting movement of the stop rod 31 and the stop rod 40, the elastic driving member 15 is compressed and deformed by the end of the stop rod 31. In addition, when the stop rod 31 moves toward the top of the stop rod 40 along the multiple limiting grooves 412 of the first abutting surface 41, a jam will be formed, and the stop rod 31 will abut against the spring sheet 20 and deform the spring sheet 20. When the stop rod 31 moves to the limiting groove 412 at the top of the stop rod 40, the jam disappears, and the stop rod 31 separates from the spring sheet 20 to make the spring sheet 20 vibrate and make a sound, thereby prompting the user, so that the user stops pressing the trigger 30 in time at the clip delivery position.

[0081] When the clip applier 100 is clamped, and the trigger 30 rotates from the clamped position to the initial position, the elastic driving member 15 returns to its original position under the action of its own elastic force, so as to drive the stopper 31 to move toward the outside of the trigger 30, and the driving structure drives the trigger 30 to rotate from the clamped position to the initial position, so that the stopper rod 31 can move toward the bottom of the stopper rod 40 along the arc-shaped second abutting surface 42, so that the stopper rod 40 returns to its original position. In addition, during the movement, the stopper rod 31 is suitable for abutting against the spring sheet 20 to drive the spring sheet 20 to rotate. During the rotation of the spring sheet 20, the limiter 22 of the spring sheet 20 rotates toward the reset driving member 14, so that the limiter 22 compresses and deforms the reset driving member 14. When the spring sheet 20 continues to rotate and separates from the stopper rod 31, the reset driving member 14 can return to its original position under the action of its own elastic force, so as to drive the spring sheet 20 to reset, so that the trigger 30 smoothly rotates from the clamped position to the initial position.
