Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular, to a continuous-fire titanium clip with a cutting function. Background Technology

[0002] Repeating titanium clips are used to clamp blood vessels and other channels, saving time on suture knotting, making the procedure convenient, quick, and faster. However, after clamping blood vessels, existing repeating titanium clips require the surgeon to put down the clip and replace the scissors, or an assistant to cut the tissue with scissors, which adds extra steps, disrupts the continuity of the surgery, and increases the number of surgical steps and time. This is especially troublesome in laparoscopic surgery, where repeated changes of surgical instruments are even more cumbersome. Therefore, we propose a repeating titanium clip with a cutting function. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-shot titanium clip with a cutting function, which allows for the direct cutting of vascular tissue after clamping a blood vessel, without the need to change to other surgical instruments.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A series of titanium clips with a cutting function includes a clamp body, a push rod disposed inside the clamp body, the push rod being movable along the length direction of the clamp body, a push block slidably disposed on the clamp body, one end of the push rod being fixedly connected to the push block, and a cutting blade being fixedly attached to the other end of the push rod. The push rod is moved by moving the push block to drive the cutting blade into or out of the clamp body.

[0006] In an optional embodiment, the surface of the clamp body is provided with a groove that extends along the length of the clamp body, and at least a portion of the push block is slidably mounted in the groove.

[0007] In an optional embodiment, the pliers further include a handle, a linkage assembly, and at least one jaw, the linkage assembly being disposed within the pliers body and movable along the axial direction of the pliers body, at least one jaw being disposed at a port of the pliers body, and the handle being disposed on the side of the pliers body, the handle driving the jaws to open and close via the linkage assembly.

[0008] In an optional embodiment, the jaws have a protrusion at the port of the jaws, which engages with the jaws to clamp as the linkage assembly moves along the jaws.

[0009] In an alternative embodiment, at least a portion of the pliers head is made of a resilient material.

[0010] In an optional embodiment, two clamps are provided, the two clamps are connected to the ends of the linkage assembly, a gap is provided between the two clamps, and the cutting blade is disposed between the two clamps.

[0011] In an optional embodiment, the push rod includes at least one rod body, at least one of the rod bodies being disposed on one side of the linkage assembly and movable along the clamp body, the other end of the rod body being fixedly connected to the portion of the push block that enters the clamp body.

[0012] In an optional embodiment, the shear blade has a notch on the side near the link assembly, the notch corresponding to the end of the link assembly.

[0013] In an optional embodiment, the travel distance of the cutting blade extending out of the clamp body is greater than the length of the clamp head extending out of the clamp body.

[0014] This utility model has the following beneficial effects:

[0015] By clamping the blood vessel with forceps, the operator slides the push block to move the push rod along the forceps body, thereby pushing the shearing blade out of the forceps body and directly cutting the blood vessel tissue with the shearing blade, avoiding the intervention of other instruments. It can be operated by a single person with one hand, reducing surgical steps and time.

[0026] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0030] Please refer to Figures 1 to 5 This utility model provides a continuous-fire titanium clip with a cutting function, including a clamp body 110. A push rod 220 is provided inside the clamp body 110. The push rod 220 can move along the length direction of the clamp body 110. A push block 200 is slidably provided on the clamp body 110. One end of the push rod 220 is fixedly connected to the push block 200, and the other end of the push rod 220 is fixed with a cutting blade 210. The push rod 220 drives the cutting blade 210 into or out of the clamp body 110 by moving the push block 200.

[0031] Typically, the repeating titanium clip also includes a handle 140, a linkage assembly 150, and at least one clamp head 130. The linkage assembly 150 is disposed within the clamp body 110 and is movable along the axial direction of the clamp body 110. At least one clamp head 130 is disposed at the port of the clamp body 110, and the handle 140 is disposed on the side of the clamp body 110. The handle 140 drives the clamp head 130 to open and close via the linkage assembly 150.

[0032] Specifically, the handle 140 is hinged to both sides of the clamp body 110, and a torsion spring can be provided at the hinge point between the two. The torsion spring can cause the handle 140 to self-reset. Further, the linkage assembly 150 includes a first linkage and a second linkage. The first linkage is disposed inside the clamp body 110 and is coaxially disposed with the clamp body 110. One end of the second linkage is hinged to the handle 140, and the other end is hinged to the first linkage. Therefore, by moving the handle 140 toward the inside of the clamp body 110, the second linkage drives the first linkage to pull the clamp head 130 into the clamp body 110, thereby clamping the vascular tissue with the clamp head 130.

[0033] More specifically, the clamp body 110 has a protrusion at its end. When the linkage assembly 150 moves along the clamp body 110, the protrusion engages with the clamp head 130, causing the clamp head 130 to clamp. At least a portion of the clamp head 130 is made of an elastic material. When the protrusion engages with the elastic portion of the clamp head 130, the clamp head 130 clamps inward, causing the metal portion of the clamp head 130 to clamp the blood vessel, thereby achieving vessel closure.

[0034] By clamping the blood vessel with forceps, the operator slides the push block 200 to move the push rod 220 along the forceps body 110, thereby pushing the shearing blade 210 out of the forceps body 110, and then directly cutting the blood vessel tissue with the shearing blade 210, avoiding the intervention of other instruments. It can be operated by a single person with one hand, reducing surgical steps and time.

[0035] Furthermore, the surface of the clamp body 110 is provided with a sliding groove 120, which extends along the length of the clamp body 110, and at least a portion of the push block 200 is slidably installed in the sliding groove 120.

[0036] By providing a groove 120 on the clamp body 110 and extending at least a portion of the groove 120 into the clamp body 110, the push rod 220 is connected to the push block 200 extending into the clamp body 110. This allows the push rod 220 to move synchronously with the push block 200 as it moves along the groove 120, thereby enabling the shearing blade 210 to be pushed out of or retracted into the clamp body 110.

[0037] In this embodiment, two clamp heads 130 are provided, and the two clamp heads 130 are connected to the end of the connecting rod assembly 150. There is a gap between the two clamp heads 130, and the cutting blade 210 is disposed between the two clamp heads 130.

[0038] By moving the handle 140 inward toward the body of the clamps 110, the first link is driven by the second link to pull the clamp head 130 into the body of the clamps 110, thereby clamping the blood vessel tissue with the two clamp heads 130. When the cutting blade 210 is pushed out by the push block 200 and the push rod 220, the blood vessel tissue can be cut directly. Furthermore, when the blood vessel tissue is clamped by the two clamp heads 130, the blood vessel tissue is prevented from shifting during the cutting process, which further improves the cutting effect.

[0039] It should be noted that the travel distance of the cutting blade 210 extending from the clamp body 110 is greater than the length of the clamp head 130 extending from the clamp body 110. When the clamp head 130 clamps the vascular tissue, the extension of the cutting blade 210 can cut the vascular tissue between the clamp heads 130, and the distance of the cutting blade 210 extending from the clamp body 110 is greater than the length of the clamp head 130 extending from the clamp body 110, which can completely cut the vascular tissue between the clamp heads 130.

[0040] Furthermore, combined Figure 4 As shown, the shearing blade 210 has a notch on the side near the connecting rod assembly 150, and the notch corresponds to the end of the connecting rod assembly 150. Since the shearing blade 210 is located at the end of the first connecting rod, by providing the notch, the shearing blade 210 can smoothly enter the clamp body 110 without interfering with the movement of the connecting rod assembly 150.

[0041] The push rod 220 includes at least one rod body, which is disposed on one side of the linkage assembly 150 and movable along the clamp body 110. The other end of the rod body is fixedly connected to the portion of the push block 200 that enters the clamp body 110. Since the linkage assembly 150 occupies a large space in the clamp body 110, by disposing the rod body of the push rod 220 on one side of the first linkage, motion interference with the linkage assembly 150 can be avoided, while improving the integration within the continuous firing titanium clip.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
