Specific implementation manners

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a transition cap for a minimally invasive surgical tissue clip that prevents detachment, including a connecting base 1. A nut 2 is threadedly connected to the upper surface of the connecting base 1. The inner wall surface of the nut 2 is fixedly connected to a first connecting pipe 3. A protection mechanism 4 is arranged on the inner wall surface of the nut 2. The outer wall surface of the first connecting pipe 3 is slidably connected to a second connecting pipe 5. A telescopic mechanism 6 is arranged on the inner wall surface of the second connecting pipe 5. A rubber plug 7 is fixedly connected to the upper surface of the second connecting pipe 5;

[0019] The protection mechanism 4 includes a threaded block 401, a limiting hole 402, a threaded groove 403, a first clamping hole 404, a first spring 405, a stop block 406 and a clamping block 407. The upper surface of the connecting base 1 is fixedly connected with the threaded block 401. The surface of the threaded block 401 is provided with the limiting hole 402. The inner wall surface of the nut 2 is provided with the threaded groove 403. One side surface of the threaded groove 403 is provided with the first clamping hole 404. The outer wall surface of the first clamping hole 404 is fixedly connected with the first spring 405. One end surface of the first spring 405 is fixedly connected with the stop block 406. One end surface of the stop block 406 is fixedly connected with the clamping block 407. Through the settings of the threaded block 401, the limiting hole 402, the threaded groove 403, the first clamping hole 404, the first spring 405, the stop block 406 and the clamping block 407, when the transition cap is connected to the tissue clamp, the threaded groove 403 on the inner wall of the nut 2 rotates along the direction of the thread of the threaded block 401, so that the nut 2 is threadedly connected to the connecting base 1. When it is screwed to the bottom, the first spring 405 will pop the stop block 406 and the clamping block 407 into the first clamping hole 404 from the limiting hole 402 to fix the nut 2 above the connecting base 1. The connecting base 1 is a part of the tissue clamp, so that the transition cap can be connected to the tissue clamp without falling off.

[0020] Furthermore, the outer wall dimension of the threaded block 401 is in line with the inner wall dimension of the threaded groove 403, and the outer wall dimension of the clamping block 407 is in line with the inner wall dimension of the limiting hole 402. Through the settings of the threaded block 401, the limiting hole 402, the threaded groove 403 and the clamping block 407, the nut 2 can be quickly installed on the connecting base 1 and fixed.

[0021] Furthermore, the outer wall dimension of the first connecting pipe 3 is in line with the dimension of the groove formed on the inner wall of the second connecting pipe 5. The first connecting pipe 3 and the second connecting pipe 5 form a vertically sliding structure. Through the settings of the first connecting pipe 3 and the second connecting pipe 5, the length of the transition cap can be increased to adapt to different surgical scenarios and tissue clamp models.

[0022] Furthermore, the telescopic mechanism 6 includes a second clamping hole 601, a second spring 602, a clamping pin 603, and a fixing hole 604. A second clamping hole 601 is formed on one side surface of the first connecting pipe 3. The outer wall surface of the second clamping hole 601 is fixedly connected with a second spring 602. One end surface of the second spring 602 is fixedly connected with a clamping pin 603. A fixing hole 604 is formed on the inner wall surface of the second connecting pipe 5. Through the arrangement of the second clamping hole 601, the second spring 602, the clamping pin 603, and the fixing hole 604, when the length of the transition cap needs to be adjusted, the first connecting pipe 3 is pulled downward, and the second spring 602 will retract the clamping pin 603 into the second clamping hole 601. When pulled to the required position, the second clamping hole 601 is aligned with the fixing hole 604, and the second spring 602 will eject the clamping pin 603 from the second clamping hole 601 into the fixing hole 604 to fix the first connecting pipe 3 inside the second connecting pipe 5, thereby completing the adjustment of the length of the transition cap.

[0023] Furthermore, the outer wall dimension of the clamping pin 603 matches the inner wall dimension of the fixing hole 604. Multiple groups of fixing holes 604 are arranged on one side of the second connecting pipe 5. Through the arrangement of the clamping pin 603 and the fixing hole 604, the fixing hole 604 limits the clamping pin 603, enabling the connection between the first connecting pipe 3 and the second connecting pipe 5 to be more stable.

[0024] Working principle: First, when the transition cap is connected to the tissue clip, the thread groove 403 on the inner wall of the nut 2 rotates along the direction of the thread of the thread block 401, so that the nut 2 is threadedly connected to the connection base 1. When screwed to the bottom, the first spring 405 will eject the stopper 406 and the locking block 407 from the limit hole 402 into the first clamping hole 404 to fix the nut 2 above the connection base 1. The connection base 1 is a part of the tissue clip, so that the transition cap is connected to the tissue clip without falling off. Secondly, when the length of the transition cap needs to be adjusted, the first connecting pipe 3 is pulled downward, and the second spring 602 will retract the clamping pin 603 into the second clamping hole 601. When pulled to the required position, the second clamping hole 601 is aligned with the fixing hole 604, and the second spring 602 will eject the clamping pin 603 from the second clamping hole 601 into the fixing hole 604 to fix the first connecting pipe 3 inside the second connecting pipe 5, thereby completing the adjustment of the length of the transition cap. In this way, the use process of a transition cap for a minimally invasive surgical tissue clip that prevents falling off is completed.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
