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.

[0029] Reference below Figure 1-Figure 4 The clip applier 100 according to the embodiment of the utility model is described. The clip applier 100 can be used to deliver the ligation clip to the tissue site of the operation, and then clamp the tissue site to stop bleeding.

[0030] like Figure 1-Figure 4As shown, the clamp applier 100 includes: a housing 10; a spring sheet 20, one end of which is fixedly mounted on the housing 10; and 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 the clamping position is located between the initial position and the clamping position along the rotation direction of the trigger 30, and the trigger 30 is suitable for abutting against the spring sheet 20 during the rotation process from the initial position to the clamping position to deform the spring sheet 20, and when the trigger 30 is rotated to the clamping position, the trigger 30 is separated from the spring sheet 20 to make the spring sheet 20 vibrate and make a sound.

[0031] Among them, one end of the spring clip 20 can be fixed to the shell 10, for example: the spring clip 20 and the shell 10 can be welded or bolted, but the utility model is not limited to this. The spring clip 20 and the shell 10 can also be connected in other ways, as long as the spring clip 20 is fixed to the shell 10.

[0032] 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 screw, or the like. However, 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.

[0033] The clip delivery position is located between the initial position and the clamping position along the rotation direction of the trigger 30. The trigger 30 is suitable for abutting against the spring sheet 20 to deform the spring sheet 20 during the rotation process from the initial position to the clip delivery position, and when the trigger 30 is rotated to the clip delivery position, the trigger 30 is separated from the spring sheet 20 to make the spring sheet 20 vibrate and make a sound, so that the user can stop pressing the trigger 30 at 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 avoiding the clip applier 100 from continuously sending the ligation clip, thereby avoiding wasting the ligation clip.

[0034] Furthermore, during the process of the trigger 30 rotating from the clamp delivery position to the initial position, the trigger 30 is also suitable for abutting against the spring sheet 20 to deform the spring sheet 20, and when the trigger 30 is separated from the spring sheet 20, the spring sheet 20 vibrates and makes a sound, thereby prompting the user of the clip applier 100 that the clamping is completed, and the trigger 30 of the clip applier 100 has returned to the initial position, and the next clamping operation can be performed. 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.

[0035] According to the clip applier 100 of the embodiment of the utility model, the trigger 30 abuts against the spring sheet 20 during the rotation process to deform the spring sheet 20, and when the trigger 30 rotates to the clip delivery position, the trigger 30 separates 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, 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 avoiding the clip applier 100 from continuously sending the ligation clip, thereby avoiding the waste of the ligation clip and the clip applier 100, thereby improving the success rate and efficiency of the operation.

[0036] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, when the trigger 30 rotates from the clip delivery position to the initial position, the trigger 30 is adapted to abut against the spring sheet 20 to deform the spring sheet 20 , and when the trigger 30 is separated from the spring sheet 20 , the spring sheet 20 vibrates and makes a sound.

[0037] Among them, an elastic member can also be installed between the trigger 30 and the shell 10. The elastic member can be an elastic member such as a spring that has elastic force and can restore its original shape after being compressed. When the trigger 30 is rotated to the clamping position to clamp the ligation clamp, the elastic force of the elastic member can drive the trigger 30 to rotate from the clamping position to the initial position. In the process of the trigger 30 rotating from the clamp delivery position to the initial position, the trigger 30 is suitable for abutting against the spring sheet 20 to deform the spring sheet 20, and when the trigger 30 is separated from the spring sheet 20, the spring sheet 20 vibrates and makes a sound, thereby prompting the user of the clip applier 100 that the clamping is completed, and the trigger 30 of the clip applier 100 has returned to its original position, and the next clamping operation can be performed, thereby improving the success rate and efficiency of the operation.

[0038] According to some embodiments of the present invention, Figure 1 and Figure 4 As shown, the trigger 30 has a boss structure 31 . When the trigger 30 rotates, the boss structure 31 is adapted to abut against the spring sheet 20 to deform the spring sheet 20 .

[0039] The trigger 30 may have a boss structure 31, and the boss structure 31 and the trigger 30 may be connected by welding, or by bolts, but the utility model is not limited thereto, and the boss structure 31 and the trigger 30 may be connected by other means, as long as the trigger 30 has the boss structure 31. During the rotation of the trigger 30, the boss structure 31 is suitable for abutting against the spring sheet 20 to deform the spring sheet 20, and when the boss structure 31 is separated from the spring sheet 20, the spring sheet 20 can vibrate and make a sound, thereby reminding the user of the clip applier 100, 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 avoiding the clip applier 100 from continuously delivering the ligation clip, thereby avoiding wasting the ligation clip.

[0040] According to some embodiments of the present invention, Figure 4 As shown, the spring piece 20 may include: a first body 21 and a second body 22 connected to each other, one end of the first body 21 is fixed to the housing 10 , the other end of the first body 21 is connected to the second body 22 , and the second body 22 is suitable for abutting against the trigger 30 .

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

[0042] One end of the first body 21 can be fixed to the housing 10, and the other end of the first body 21 is connected to the second body 22. The second body 22 is suitable for abutting against the trigger 30, so that when the trigger 30 rotates, the boss structure 31 of the trigger 30 abuts against the second body 22 to deform the spring sheet 20, and when the trigger 30 rotates to the clamp delivery position, the trigger 30 is separated from the spring sheet 20 to make the spring sheet 20 vibrate and make a sound, so that the clamp applier 100 sends an obvious prompt when delivering the clamp to the pliers head, so that the user can stop pressing the trigger 30 in time at the clamp delivery position.

[0043] According to some embodiments of the present invention, Figure 4 As shown, an angle may be formed between the second body 22 and the first body 21. Specifically, the angle between the second body 22 and the first body 21 may be reasonably set and adjusted according to actual conditions, and is not specifically limited here, as long as it can meet the normal operation of the clip applier 100. The second body 22 may be bent toward the trigger 30, so that during the rotation of the trigger 30, the boss structure 31 of the trigger 30 may abut against the second body 22 to deform the spring sheet 20, thereby improving the working reliability of the clip applier 100.

[0044] According to some embodiments of the present invention, Figure 4 As shown, the housing 10 may be formed with a support portion 11 , which is located below the first body 21 , and the support portion 11 abuts against the first body 21 to support the first body 21 .

[0045] The housing 10 may be formed with a support portion 11, for example, the support portion 11 and the housing 10 may be integrally formed, or the support portion 11 and the housing 10 may be welded, or the support portion 11 and the housing 10 may be bolted, but the present invention is not limited thereto, and the support portion 11 and the housing 10 may be connected in other ways, as long as the housing 10 is formed with the support portion 11. The support portion 11 is located below the first body 21, and when the trigger 30 rotates so that the boss structure 31 of the trigger 30 abuts against the second body 22 to deform the spring piece 20, and the abutment of the support portion 11 against the first body 21 can support the first body 21, reduce the deformation of the first body 21, and because the first body 21 is connected to the second body 22, the first body 21 plays a role in lifting and supporting the second body 22, thereby preventing the second body 22 from being excessively deformed and unable to restore its original shape, thereby improving the service life and reliability of the spring piece 20.

[0046] According to some embodiments of the present invention, Figure 4 As shown, the surface of the support portion 11 facing the first body 21 can be a first plane 12, and the surface of the first body 21 facing the support portion 11 can be a second plane 211. The first plane 12 and the second plane 211 abut against each other, so that the support portion 11 can reliably support the first body 21, thereby further preventing the spring piece 20 from being excessively deformed and unable to restore its original shape, thereby further improving the service life and reliability of the spring piece 20.

[0047] According to some embodiments of the present invention, Figure 4 As shown, the housing 10 can be formed with a mounting column 13, the mounting column 13 defines a mounting hole 14, the mounting column 13 has a limiting notch 131 connected to the mounting hole 14, a column structure 212 is formed at one end of the first body 21, the column structure 212 is assembled in the mounting hole 14, and the first body 21 is passed through the limiting notch 131.

[0048] The housing 10 may be formed with a mounting post 13, and the mounting post 13 and the housing 10 may be integrally formed, or the mounting post 13 and the housing 10 may be connected by welding, but the present invention is not limited thereto, and the mounting post 13 and the housing 10 may be connected by other means, as long as the housing 10 is formed with the mounting post 13. The mounting post 13 may define a mounting hole 14, and the mounting post 13 has a limiting notch 131 connected to the mounting hole 14, and the limiting notch 131 may be arranged corresponding to the first body 21, so as to facilitate the first body 21 to pass through the limiting notch 131. A column structure 212 may be formed at one end of the first body 21, and the column structure 212 is assembled in the mounting hole 14, for example: the column structure 212 and the mounting hole 14 may be assembled by an interference fit, so that the column structure 212 and the mounting hole 14 are tightly connected, but the present invention is not limited thereto, and the column structure 212 and the mounting hole 14 may be assembled by other means, as long as the body structure is assembled in the mounting hole 14. Therefore, the first body 21 is inserted into the limiting notch 131 , and the column structure 212 of the first body 21 is assembled into the mounting hole 14 , which can ensure that the spring piece 20 is firmly connected to the housing 10 , thereby preventing the spring piece 20 from falling off the housing 10 , thereby improving the safety and reliability of the clip applier 100 .

[0049] According to some embodiments of the present invention, the spring clip 20 can be constructed as a steel part or a beryllium copper part.

[0050] According to some embodiments of the utility model, the clamp applier 100 may further include: an alarm device, a first sensor and a second sensor, wherein the first sensor is fixed to the housing 10, and the second sensor is fixed to the trigger 30. When the trigger 30 rotates from an initial position to a clamp delivery position, the first sensor and the second sensor are sensed to enable the alarm device to send out an alarm message.

[0051] Among them, the first sensing component is fixed to the shell 10. For example, the first sensor and the shell 10 can be connected by bolts, or the first sensor and the shell 10 can be connected by snap-fitting. However, the utility model is not limited to this.
