Description

Technical Field

[0001] The utility model relates to the technical field of vascular anastomosis, and particularly relates to a vascular clip for vascular anastomosis. Background Art

[0002] For vascular surgery, anastomosing blood vessels, especially some small blood vessels, is a very difficult task. This task requires at least two physicians to cooperate very tacitly using multiple forceps, vascular clips and needle holders to complete. The quality and duration of vascular anastomosis are directly related to the prognosis of patients. For example, for replantation of severed palms, multiple blood vessels may need to be anastomosed, and completing the vascular anastomosis as soon as possible can greatly improve the survival rate of the severed palm.

[0003] For the already narrow operating space, the cooperation of multiple instruments and multiple hands has serious problems. The cross-collision between instruments and the obstruction of the vision by multiple hands have become obstacles to vascular anastomosis. Summary of the Utility Model

[0004] The purpose of the utility model is to address the deficiencies of the prior art and provide a vascular clip for vascular anastomosis, which can greatly improve the anastomosis quality and speed of physicians, and can provide reliable vision and operating freedom in a narrow surgical space.

[0005] To solve the above technical problems, the utility model provides a vascular clip for vascular anastomosis, including a fixed rod and a movable rod. One end of the fixed rod is provided with a fixed front fork, and a plurality of needle holes are opened on the fixed front fork. One end of the movable rod is provided with a movable front fork, and a plurality of pins are arranged on the movable front fork. The pins are perpendicular to the movable front fork, and the plurality of pins correspond to the plurality of needle holes one by one. The length of the pins is greater than the length of the needle holes. The movable rod is arranged directly below the fixed rod, and the movable rod is rotatably connected to the fixed rod so that the upper end of the pin can pass through the needle hole to fix the blood vessel on the fixed front fork by the upper end of the pin.

[0006] Further, the movable rod and the fixed rod are rotatably connected through a rotating shaft, and the rotating shaft is arranged at the end of the movable rod or the fixed rod.

[0007] Further, the movable rod and the fixed rod are rotatably connected through a rotating shaft, the rotating shaft is arranged at a position close to the middle of the fixed rod, the movable rod includes a control section and a rotating section, and there is an included angle between the control section and the rotating section. The rotating shaft is arranged at the connection of the control section and the rotating section.

[0008] Further, an installation seat is arranged on the fixed rod, the rotating shaft is fixedly arranged on the installation seat, and the movable rod is rotatably connected to the rotating shaft.

[0009] Further, a spring is disposed between the movable rod and the fixed rod. Two ends of the spring are respectively connected to the movable rod and the fixed rod. The spring is used to fix the fitting or separation of the front fork and the movable front fork.

[0010] Further, a threaded hole is formed in the fixed rod, and a bolt is disposed in the threaded hole. One end of the bolt passes through the fixed rod and abuts against the movable rod.

[0011] Further, the spring and the bolt are coaxially arranged.

[0012] Further, the angles at the bifurcations of the fixed front fork and the movable front fork are both 60°.

[0013] Further, the pins are arranged at two ends and the bifurcation of the movable front fork.

[0014] Further, a scale is arranged on the side surface of the fixed front fork, so that the sutures are evenly distributed during blood vessel anastomosis.

[0015] Further, the mounting seat includes two mounting blocks. The mounting blocks are fixed on both sides of the fixed rod, and the rotating shaft is fixed between the two mounting blocks.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. By rotating the movable rod, the fixed front fork and the movable front fork are fitted, so that the pins pass through the pin holes. At this time, the end of the blood vessel can pass through the fixed front fork from below the movable front fork, and the pins can pass through the edge of the blood vessel, thereby fixing the end of the blood vessel on the fixed front fork for anastomosis with other blood vessels. Other blood vessels can also be fixed by using this blood vessel clamp. After the anastomosis is completed, the movable rod is directly rotated, and the blood vessel can be separated from the fixed front fork, with little damage to the blood vessel. Therefore, by using this blood vessel clamp, the clamping operation of the blood vessel can be completed in a limited narrow space, which is beneficial to improving the quality and efficiency of blood vessel anastomosis.

[0018] 2. By providing the bolt, the movable rod can be restricted to prevent the movable rod from rotating during the operation.

[0019] 3. The angles at the bifurcations of the fixed front fork and the movable front fork of the present utility model are both 60°, and the pins are arranged at two ends and the bifurcation of the movable front fork, so that the blood vessel is in an equilateral triangle shape when fixed on the fixed front fork, which is convenient for anastomosis.

[0020] 4. By arranging a scale on the side surface of the fixed front fork, the sutures are more evenly distributed during anastomosis, providing a more optimized tension distribution. Description of the Drawings

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] Embodiment 1

[0029] As Figure 1 shown, this embodiment provides a vascular clip for vascular anastomosis, including a fixed rod 1 and a movable rod 2, and the movable rod 2 is arranged directly below the fixed rod 1.

[0030] As Figure 3 shown, one end of the fixed rod 1 is integrally provided with a fixed front fork 7, and a plurality of pin holes 11 are opened on the fixed front fork 7. In this embodiment, three pin holes 11 are opened on the fixed front fork 7, and the three pin holes 11 are respectively opened at two ends and the bifurcation of the fixed front fork 7. A mounting seat 9 is provided on the fixed rod 1. As Figure 5 shown, the mounting seat 9 includes two mounting blocks, the mounting blocks are fixed on both sides of the fixed rod 1, and a rotating shaft 10 is vertically and fixedly arranged between the two mounting blocks. The movable rod 2 is rotatably connected to the fixed rod 1 through the rotating shaft 10. A threaded hole is opened on the fixed rod 1, the threaded hole is arranged on the side of the mounting seat 9 away from the fixed front fork 7, and a bolt 12 is arranged in the threaded hole. The lower end of the bolt 12 can pass through the fixed rod 1 and abut against the movable rod 2.

[0031] As Figure 4As shown, one end of the movable rod 2 is integrally provided with a movable front fork 6. A plurality of pins 5 are arranged on the movable front fork 6. The pins 5 and the pin holes 11 are arranged in one-to-one correspondence. The length of the pins 5 is greater than the length of the pin holes 11, so that the upper ends of the pins 5 can pass through the pin holes 11 to fix the blood vessel.

[0032] In this embodiment, the angles at the bifurcations of the fixed front fork 7 and the movable front fork 6 are both 60°. When the blood vessel is fixed on the fixed front fork 7, it forms an equilateral triangle, which is convenient for anastomosis.

[0033] The movable rod 2 includes a control section 3 and a rotating section 4. An included angle is provided between the control section 3 and the rotating section 4. The rotating shaft 10 is arranged at the connection of the control section 3 and the rotating section 4. The movable front fork 6 is arranged at one end of the rotating section 4 away from the control section 3. A spring 8 is arranged between the control section 3 of the movable rod 2 and the fixed rod 1. The spring 8 and the bolt 12 are coaxially arranged. The two ends of the spring 8 are respectively fixedly connected to the movable rod 2 and the fixed rod 1. In this embodiment, the spring 8 is in a compressed state. That is, when the bolt 12 does not abut against the movable rod 2, under the action of the spring 8, the movable front fork 6 will fit with the fixed front fork 7, so that the pins 5 are inserted into the pin holes 11. At this time, the bolt 12 can be rotated to make the bolt 12 abut against the movable rod 2 to prevent the movable rod 2 from rotating during the operation. After the blood vessel anastomosis is completed, the bolt 12 can be unscrewed so that the bolt 12 does not abut against the movable rod 2. At this time, by pinching the fixed rod 1 and the control section 3 of the movable rod 2, the movable rod 2 can be rotated clockwise to separate the movable front fork 6 from the fixed front fork 7, and the blood vessel will also automatically detach, with little damage to the blood vessel. In addition, by adjusting the bolt 12, the length of the pins 5 protruding from the pin holes 11 can be controlled to meet the different requirements of different doctors for the length of the pins 5.

[0034] In this embodiment, a scale is also provided on the side of the fixed front fork 7. By setting the scale, the suture distribution during anastomosis is more uniform, providing a more optimized tension distribution and improving the anastomosis quality.

[0035] The usage method of this blood vessel clip is as follows:

[0036] In the initial state, under the action of the spring 8, the movable front fork 6 of the movable rod 2 fits with the fixed front fork 7, and the pins 5 pass through the pin holes 11. At this time, the bolt 12 is rotated to make the bolt 12 abut against the movable rod 2 to prevent the movable rod 2 from rotating during the operation. At this time, the state of the blood vessel clip is as Figure 2 shown.

[0037] Use scissors to trim the stumps of the two blood vessels to be anastomosed. Hold the blood vessel clamp, and use forceps to pass the stump of one blood vessel through the movable front fork 6 and the fixed front fork 7. Turn the stump of the blood vessel outward so that the stitch 5 passes through the edge of the stump of the blood vessel. At this time, the stitch 5 fixes the blood vessel on the fixed front fork 7. Fix the other blood vessel with another blood vessel clamp. After the stumps of the two blood vessels are fixed, anastomosis can be started. During the anastomosis process, sutures can be made according to the scale. After the anastomosis is completed, turn the bolt 12 to cancel the limit of the bolt 12 on the movable rod 2. At this time, pinch the control section 3 of the fixed rod 1 and the movable rod 2, and the movable rod 2 can be rotated clockwise to separate the movable front fork 6 from the fixed front fork 7, and the blood vessel will also automatically separate, with little damage to the blood vessel. At this time, the state of the blood vessel clamp is as Figure 1 shown.

[0038] Embodiment 2

[0039] Compared with Embodiment 1, the difference in Embodiment 2 lies in the arrangement position of the mounting seat 9 and the spring 8. In this embodiment, the mounting seat 9 is arranged at one end of the fixed rod 1 away from the fixed front fork 7, and the hinge joint of the movable rod 2 and the fixed rod 1 is located at their left end. At this time, the movable rod 2 and the fixed rod 1 are similar to forceps. The spring 8 is always in a contracted state.

[0040] Embodiment 3

[0041] Compared with Embodiment 1, the difference in Embodiment 2 lies in the arrangement position of the spring 8. In this embodiment, the spring 8 is arranged between the rotating section 4 and the fixed rod 1, and the spring 8 is always in a contracted state.
