Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a tissue clip filling assembly of a continuous clip applier, which is suitable for continuously applying tissue clips in the process of closing tissues or blood vessels. Background Art

[0002] Tissue clips are primarily used to clamp blood vessels to stop bleeding or close tubular tissues during surgery, including small and medium-sized arteries and veins, bile ducts, etc. The number of tissue clips used in each surgery ranges from 2 to 15. Conventional practice involves a nurse placing a tissue clip into a clip applier and handing it to the doctor before surgery. The doctor then inserts the clip applier into the trocar channel, completes the tissue clip closure, removes the clip applier, and the nurse installs a second tissue clip. This process is repeated. Each clip application takes a long time, prolonging the surgery. Furthermore, the repeated insertion and removal of the clip applier from the human body can cause significant damage and increase risks. Therefore, a device capable of continuous clip application is needed to ensure that the clip applier does not need to be frequently inserted and removed during surgery.

[0003] Some clip appliers can achieve continuous firing and have a clipping function, but this is a disposable medical device. 10 to 20 titanium clips are installed in the clip applier mechanism at one time. In actual surgery, it may not be necessary to use such a large number of tissue clips. If they are not used up, they will be thrown away together with the clip applier, which obviously causes a waste of resources. In addition, the titanium clips used for ligation are inelastic, easy to conduct electricity, cannot be absorbed by the human body, and affect postoperative imaging examinations such as CT or MRI.

[0004] The pre-loaded tissue clips in some clip appliers are in a compressed state during production. If a long period of time passes between production and use, the tissue clips remain in a compressed state, which may cause the tissue clips to fail. If a tissue clip fails during surgery, it may affect the surgical process and patient safety. Utility Model Content

[0024] For the convenience of those of ordinary skill in the art to understand and implement the present utility model, the present utility model will be further described in detail below in conjunction with embodiments. The embodiments described herein are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

[0025] Embodiment 1:

[0026] A tissue clip loading assembly of a continuous firing clip applicator, comprising an elongated push cover 1, a push block 2, an elongated storage tank body 3, a mounting block 4, and a forceps head 8. The cross-sectional shape of the storage tank body 3 is U-shaped. The bottom of the push cover 1 is slidably connected to the top of the storage tank body 3. A push groove 5 is provided on the mounting block 4. The front end of the push groove 5 is aligned and connected to the rear end of the storage tank body 3. A push block 2 is arranged in the push groove 5. The top of the push block 2 is fixedly connected to the bottom of the push cover 1. The rear end of the push cover 1 is connected to one end of the loading cover 11. A loading port 10 is provided on the loading cover 11. The loading port 10 is located above the push groove 5. The push block 2 is located behind the loading port 10. The forceps head 8 is arranged at the front part of the storage tank body 3.

[0027] The tissue clip 9 is placed into the push groove 5 from the loading port 10, and then the push cover 1 is pushed forward. The push cover 1 drives the push block 2, so as to push the tissue clip 9 in the push groove 5 into the storage tank body 3; then the push cover 1 is pulled backward to reset the push cover 1 and the push block 2; finally, repeating the above two operations can sequentially load multiple tissue clips 9 into the storage tank body 3 until the storage tank body 3 is full of tissue clips 9.

[0028] As an implementable mode, a limit sliding groove is provided on the top of the storage tank body 3, a limit sliding block is arranged on the limit sliding groove, the limit sliding block is fixedly connected to the bottom of the push cover 1, the moving direction of the limit sliding block in the limit sliding groove is parallel to the length direction of the storage tank body 3, and the movable distance of the limit sliding block in the limit sliding groove enables only one tissue clip 9 to be pushed out of the storage tank body 3 into the forceps head 8 each time.

[0029] A plurality of first type of elastic pressing pieces 6 are provided at the bottom of the push cover 1. All the first type of elastic pressing pieces 6 are arranged at equal intervals at the bottom of the push cover 1. The rear end of the first type of elastic pressing piece 6 is connected to the bottom of the push cover 1. The front end of the first type of elastic pressing piece 6 opens downward. The first type of elastic pressing piece 6 forms a set angle with the push cover 1;

[0030] A plurality of second-type elastic pressing pieces 7 are provided on the inner bottom surface of the storage tank body 3. All the second-type elastic pressing pieces 7 are arranged at equal intervals on the inner bottom surface of the storage tank body 3. The rear ends of the second-type elastic pressing pieces 7 are connected to the inner bottom surface of the storage tank body 3. The front ends of the second-type elastic pressing pieces 7 are opened upward. The second-type elastic pressing pieces 7 form a set angle with the storage tank body 3.

[0031] When the push cover 1 moves forward, it will drive the first type of elastic pressing piece 6 to move forward, and the first type of elastic pressing piece 6 will push the tissue clamp 9 to cross the second type of elastic pressing piece 7 in front, thereby entering between the two adjacent second type of elastic pressing pieces 7 again; when the push cover 1 moves backward, it will drive the first type of elastic pressing piece 6 to move backward, but due to the obstruction of the second type of elastic pressing piece 7 behind each tissue clamp 9, the tissue clamp 9 stays in place, thereby completing the reset of the push cover 1, the push block 2, and the first type of elastic pressing piece 6.

[0032] When the push cover 1 is reset, the front end of each first-class elastic pressing piece 6 presses against the front end of the second-class elastic pressing piece 7 at the corresponding position, thereby jointly preventing the tissue clip 9 from moving backward. When the push cover 1 is pushed, each first-class elastic pressing piece 6 slowly releases the mutual pressure from the second-class elastic pressing piece 7 at the original corresponding position until they are offset from each other, allowing the first-class elastic pressing pieces 6 to open outward, thereby pushing the tissue clips 9 already in the storage tank 3 forward. When the storage tank is full of tissue clips 9, the push cover 1 is pushed forward again, and the tissue clip 9 at the front of the storage tank 3 will leave the storage tank 3 and enter the clamp head 8 at the front of the storage tank 3, and the tissue clips 9 at the rear will move forward in turn.

[0033] Example 2:

[0034] On the basis of Example 1, the distance between the groove walls on both sides of the pushing groove 5 gradually increases from front to back. After the open tissue clip 9 enters the pushing groove 5 from the loading port 10, the pushing block 2 pushes the tissue clip 9 forward, and the two clamping arms of the tissue clip 9 will gradually turn into a closed state along the groove walls on both sides of the pushing groove 5, and finally enter the storage groove body 3 in a closed state.

[0035] It should be noted that the embodiments described in this utility model are merely illustrative of the spirit of this utility model. Those skilled in the art of the technology to which this utility model relates may make various modifications, additions, or substitute similar methods to the described embodiments without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
