Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a detachable vascular clip continuous firing forceps. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are directly or indirectly used on the human body. With the development of the medical industry, minimally invasive surgical instruments are increasingly widely used in clinical practice. In minimally invasive surgery, vascular clips can play a role in hemostasis or controlling the blood flow direction of blood vessels, thus ensuring the smooth completion of the surgery.

[0003] For example, patent CN202210029462.0 discloses a polymer vascular clip automatic continuous firing device, which adopts a polymer vascular clip and an automatic continuous firing applicator forceps. During the operation, it can efficiently and continuously ligate blood vessels. The polymer vascular clip with good biocompatibility and a unique 0.1mm convex head design can effectively increase the clamping friction of the vascular clip, improve the safety factor, have no tissue cutting, and can be visualized under X-ray.

[0004] In this solution, it is difficult to install and disassemble the forceps housing and the front-end delivery tube, and it is impossible to quickly replenish or replace the vascular clips. Summary of the Utility Model

[0005] The utility model aims at the deficiencies of the prior art and provides the following technical solution: a detachable vascular clip continuous firing forceps, including a handle, a delivery tube, and a trigger. The surface of the handle is rotatably connected with a trigger that penetrates through it. One end of the delivery tube extends into the handle and is slidably connected with the trigger. One end of the delivery tube is fixedly connected with a threaded sleeve. The surface of the threaded sleeve is threadedly connected with a first kit. The surface of the first kit is provided with a buckle. The surface of the first kit is sleeved with a second kit. The surface of the second kit is provided with a card slot. The surface of the second kit is provided with an annular protrusion. The end of the handle is provided with an end rib. The buckle passes through the card slot and is mutually engaged with the end rib through the annular protrusion. The side of the buckle close to the end rib is provided with an inclined chamfer.

[0006] As an improvement of the above technical solution, the surface of the card slot is provided with an inclined chamfer and is correspondingly arranged with the buckle.

[0007] As an improvement of the above technical solution, the side of the buckle away from the end rib is provided with an inclined chamfer, and the end of the second kit close to the threaded sleeve is provided with an inclined chamfer.

[0008] As an improvement of the above technical solution, the surface of the end rib is provided with two symmetrically arranged rounded chamfers.

[0009] Advantages of the Utility Model

[0010] When it is necessary to remove the delivery tube, the delivery tube, the first kit and the second kit can be removed from the handle by withdrawing the buckle from the card slot, realizing the detachable of the delivery tube. Through the cooperation of the first kit and the second kit, the detachable installation of the delivery tube and the handle can be realized, which is convenient for replacing the delivery tube or replenishing the vascular clips after the vascular clips in the delivery tube are used up.

[0016] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution: a detachable vascular clip continuous firing forceps, including a handle 1, a delivery tube 2, and a trigger 3. The surface of the handle 1 is rotatably connected with a trigger 3 that penetrates it. One end of the delivery tube 2 extends into the handle 1 and is slidably connected with the trigger 3. One end of the delivery tube 2 is fixedly connected with a threaded sleeve 4. The surface of the threaded sleeve 4 is threadedly connected with a first kit 5. The surface of the first kit 5 is provided with a buckle 6. The surface of the first kit 5 is sleeved with a second kit 7. The surface of the second kit 7 is provided with a card slot 8. The surface of the second kit 7 is provided with an annular protrusion 9. The end of the handle 1 is provided with an end rib 10. The buckle 6 passes through the card slot 8 and is mutually engaged with the end rib 10 through the annular protrusion 9. One side of the buckle 6 close to the end rib 10 is provided with an inclined chamfer.

[0018] In this implementation scheme, the buckle 6 on the first kit 5 penetrates through the card slot 8, and the buckle 6 and the annular protrusion 9 on the second kit 7 respectively abut against the opposite sides of the end rib 10 at the opening of the end of the handle 1 to achieve fixation. When the conveying pipe 2 needs to be disassembled, first move the conveying pipe 2, so that the end rib 10 presses the chamfered part of the buckle 6, and then the buckle 6 rotates on the surface of the second kit 7, so that the buckle 6 disengages from the clamping of the end rib 10, and then the conveying pipe 2 can be disassembled. Then rotate the first kit 5, so that the first kit 5 disengages from the threaded sleeve 4 to complete further disassembly, so as to facilitate the disinfection and maintenance of the first kit 5 and the second kit 7. Finally, press the buckle 6 so that the buckle 6 disengages from the card slot 8, and the first kit 5 disengages from the second kit 7 to complete further disassembly, so as to facilitate better disinfection and maintenance of the first kit 5 and the second kit 7. When the conveying pipe 2 needs to be removed, the conveying pipe 2, the first kit 5 and the second kit 7 can be removed from the handle 1 by withdrawing the buckle 6 from the card slot 8, realizing the detachable of the conveying pipe 2. Through the cooperation of the first kit 5 and the second kit 7, the detachable installation of the conveying pipe 2 and the handle 1 can be realized, which can facilitate the replacement of the conveying pipe 2 or the replenishment of the vascular clip after the vascular clip in the conveying pipe 2 is used up.

[0019] Specifically, the surface of the card slot 8 is provided with a chamfer, which is correspondingly arranged with the buckle 6.

[0020] In this embodiment, by providing a chamfer on the surface of the card slot 8, it is convenient to cooperate with the chamfer of the buckle 6, so that the first kit 5 can be more conveniently taken out from the inside of the second kit 7.

[0021] Specifically, a chamfer is provided on the side of the buckle 6 away from the end rib 10, and a chamfer is provided at one end of the second kit 7 close to the threaded sleeve 4.

[0022] In this embodiment, through the cooperation of the chamfer of the buckle 6 and the chamfer of the second kit 7, it is convenient for the buckle 6 to rotate, so that the first kit 5 is conveniently installed inside the second kit 7. At the same time, the chamfer provided on the side of the buckle 6 away from the end rib 10 also facilitates the buckle 6 to be inserted into the inside of the end rib 10, so as to facilitate the installation of the conveying pipe 2.

[0023] Specifically, two symmetrically arranged rounded corners are provided on the surface of the end rib 10.

[0024] In this embodiment, when the conveying pipe 2 is disassembled, one end of the end rib 10 slides on the surface of the buckle 6. By providing two symmetrically arranged rounded corners on the surface of the end rib 10, the friction between the two during relative sliding can be reduced, so as to facilitate the disassembly and installation of the conveying pipe 2.

[0025] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
