[0030] The following detailed descriptions are all exemplary descriptions, aiming to provide further detailed descriptions of the present utility model. Unless otherwise specified, all technical terms adopted by the present utility model have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs. The terms used in the present utility model are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present utility model.

[0031] Embodiment 1

[0032] As Figure 1 and Figure 2 shown, the blood vessel clip traction fixator includes

[0033] a connecting rod 1, and the connecting rod 1 is a straight rod;

[0034] a fastening device 2, there are multiple fastening devices 2, and the fastening device 2 is provided with a connecting part 21 and a fastening part 22;

[0035] The connecting part 21 is used to connect to the connecting rod 1, and the fastening part 22 is used to install and fix the hand-held end of the blood vessel clip.

[0036] Specifically, the fixator includes a straight rod-shaped connecting rod 1, which is made of a high-strength material, such as stainless steel or titanium alloy, to ensure sufficient stability and durability during the operation. The diameter and length of the connecting rod 1 are designed according to the surgical requirements to adapt to different sizes and lengths of blood vessel anastomosis operations. The surface of the connecting rod 1 can be specially treated, such as polishing or coating, to provide good sliding performance and reduce damage to the surrounding tissues.

[0037] The fixator is equipped with multiple fastening devices 2, which are evenly distributed on the connecting rod 1 for fixing the blood vessel clips. Each fastening device 2 can be operated independently to adapt to the fixing requirements of blood vessel clips at different positions.

[0038] Each fastening device 2 includes a connecting portion 21, which can be designed as a through-hole, and the cross-sectional shape of the through-hole matches the cross-sectional shape of the connecting rod 1. For example, if the connecting rod 1 is circular, the through-hole is also circular. This design allows the fastening device 2 to slide freely along the connecting rod 1 to facilitate the adjustment of the position of the fixator.

[0039] The fastening portion 22 of the fastening device 2 is designed for installing and fixing the handheld end of the vascular clip. The fastening portion 22 can include an insertion opening 221, and its size and shape are designed to be able to fit the outer shape of the handheld end of the vascular clip to ensure that the vascular clip can be stably inserted and fixed.

[0040] As a preferred example, the connecting portion 21 is a through-hole, the cross-section of the through-hole matches the cross-section of the connecting rod 1, and the fastening device 2 is slidably connected to the connecting rod 1 through the connecting portion 21.

[0041] The connecting portion 21 is specifically a through-hole, which is a part of the fastening device 2 and is designed to match the cross-section of the connecting rod 1. For example, if the cross-section of the connecting rod 1 is circular, the through-hole is also circular; if the cross-section of the connecting rod 1 is square, the through-hole is also square. This design ensures an exact fit between the connecting portion 21 and the connecting rod 1, allowing the fastening device 2 to slide smoothly along the connecting rod 1. The diameter of the through-hole is slightly larger than the diameter of the connecting rod 1 to ensure that the fastening device 2 can move freely on the connecting rod 1 while maintaining sufficient friction to prevent accidental sliding during the operation. The inner wall of the through-hole can be designed to be smooth or textured to provide appropriate friction and prevent the vascular clip from sliding.

[0042] As a specific example, there are two fastening devices 2.

[0043] Each fastening device 2 is connected to a vascular clip, and the two vascular clips can fix the two ends of the blood vessel to complete the operation, which is convenient and fast.

[0044] As a preferred example, the insertion openings 221 of multiple fastening devices 2 face the same direction and are located on the same straight line.

[0045] Specifically, the design of aligning the insertion openings 221 on the same straight line enables the vascular clips to be fixed in a consistent direction and angle when inserted, which helps to improve the accuracy and consistency of the operation. In addition, this design also facilitates the surgeon to quickly position and fix the vascular clips. Since the insertion openings 221 face the same direction and are located on the same straight line, multiple fastening devices 2 can work together to fix multiple vascular clips simultaneously. This design is particularly suitable for situations where multiple segments of blood vessels need to be fixed simultaneously or synchronous operations are required in complex surgeries. This design simplifies the operation process of the surgeon because the surgeon can adjust and fix all the vascular clips along the same straight line at one time, reducing the number of adjustments and the complexity that the surgeon needs to perform during the operation.

[0046] As a preferred example, the fastening portion 22 includes an insertion opening 221, a threaded hole 222 penetrating through the insertion opening 221, and a fastening bolt 223 disposed in the threaded hole 222. The insertion opening 221 is for inserting the hand-held end of the vascular clip.

[0047] Specifically, the insertion opening 221 is an opening of the fastening portion 22, and its size and shape are designed to match the hand-held end of the vascular clip so that the vascular clip can be precisely inserted and fixed. The inner wall of the insertion opening 221 can be designed to be smooth or textured to provide appropriate frictional force to ensure that the vascular clip does not slide or shift during the operation. The threaded hole 222 penetrating through the insertion opening 221 provides a thread for the fastening bolt 223 to be screwed in. The inner diameter of the threaded hole 222 matches the outer diameter of the fastening bolt 223 to ensure that the bolt can be smoothly and firmly screwed in. The design of the threaded hole 222 allows the clamping pressure on the vascular clip to be adjusted by tightening the bolt. The fastening bolt 223 disposed in the threaded hole 222 is used to fix the vascular clip. The bolt can be provided with a tightening head for easy manual tightening to adapt to vascular tissues of different thicknesses and elasticities. The design of the bolt should take into account the convenience of operation and the fixing effect on the vascular clip. The operator inserts the hand-held end of the vascular clip into the insertion opening 221 of the fastening portion 22, and then tightens the fastening bolt 223 until the vascular clip is firmly fixed on the fastening device 2. The fastening bolt 223 can be designed with anti-slip texture for easy operation by the operator.

[0048] After the fastening bolt 223 is tightened in place, a locking mechanism may be further included to ensure that the bolt does not accidentally loosen during the operation. The locking mechanism can be a locking groove on the bolt head or other forms of locking structures.

[0049] As a preferred example, a locking mechanism 3 is provided between the connecting portion 21 and the connecting rod 1 for locking the position after the fastening device 2 moves to the target position.

[0050] Specifically, the locking mechanism 3 is provided between the connecting portion 21 of each fastening device 2 and the connecting rod 1. The function of the locking mechanism 3 is to fix the position of the fastening device 2 after it moves along the connecting rod 1 to the target position required for the operation, preventing displacement during the operation. The locking mechanism 3 can adopt various forms. For example, it can be a rotatable locking screw. When the fastening device 2 moves to the appropriate position, the locking screw is rotated into the locking groove to lock the position of the fastening device 2. Alternatively, the locking mechanism 3 can be a spring-loaded jaw system. When the fastening device 2 is in place, the jaws can lock the fastening device 2 automatically or manually. The design of the locking mechanism 3 should be convenient for the operator to operate. After the fastening device 2 moves to the target position, the operator can easily activate the locking mechanism 3 without complex adjustments or using additional tools. The locking mechanism 3 must be able to provide sufficient locking force to ensure that the fastening device 2 does not displace even under a certain external force during the operation. This requires that the material and structural design of the locking mechanism 3 can withstand the forces that may occur during the operation.

[0051] As a preferred example, positioning scales are provided on the connecting rod 1.

[0052] The scales are designed to help the operator accurately determine the position of the fastening device 2, thereby precisely controlling the relative position and spacing of the vascular clips. The positioning scales are evenly distributed along the length direction of the connecting rod 1, forming a clear scale line. The scales can be in the form of grooves, protrusions, or marks, etc., and are designed to be easy to observe and identify for quick positioning during the operation. Through the positioning scales, the operator can quickly adjust the fastening device 2 to the preset position to achieve precise control of the spacing of the vascular clips. This is particularly important for vascular anastomosis operations that require precise alignment of bilateral blood vessels. The synergistic effect of the positioning scales and the fastening device 2 enables the operator to move the fastening device 2 to the target position according to the scale indication and use the fastening device 2 to fix the vascular clips to achieve precise positioning of the vascular clips.

[0053] As a preferred example, the cross-section of the connecting rod 1 is square.

[0054] The connecting rod 1 with a square cross-section is convenient for precise positioning and measurement during the operation because its edges are clear and easy to align with the positioning scales or external measurement tools. In addition, the square cross-section provides a larger contact area, which helps to improve the stability between the fastening device 2 and the connecting rod 1. The connecting rod 1 with a square cross-section is convenient for precise positioning and measurement during the operation because its edges are clear and easy to align with the positioning scales or external measurement tools. In addition, the square cross-section provides a larger contact area, which helps to improve the stability between the fastening device 2 and the connecting rod 1.

[0055] The square cross-section prevents angular changes between multiple fastening devices 2 and improves the anastomosis stability.

[0056] As a preferred example, the cross section of the connecting rod 1 is circular.

[0057] The circular cross-section facilitates adjustment of the angles between the plurality of fastening devices 2 to adapt to different surgical situations.

[0058] As a preferred example, one of the fastening devices 2 is fixedly connected to the connecting rod 1 , and the other fastening device 2 is slidably connected to the connecting rod 1 .

[0059] The fixedly connected fastening device 2 is designed to occupy a fixed position on the connecting rod 1. This design can provide a reference point or reference position to facilitate the operator to locate one end of the vascular clamp. The fastening device 2 slidably connected to the connecting rod 1 allows movement along the length of the connecting rod 1 to adapt to blood vessels of different lengths or surgical requirements. The fixedly connected fastening device 2 provides a stable reference, while the slidably connected fastening device 2 allows fine adjustment and precise positioning. The combination of the two can improve the accuracy of the vascular clamp positioning. It provides dual functions of fixed and adjustable to adapt to different surgical requirements and facilitate quick single-handed operation.

[0060] An example of the method of using the present application is as follows:

[0061] Place the vascular clamp traction fixture at an appropriate position to ensure that the horizontal or vertical state of the connecting rod 1 meets the surgical requirements.

[0062] As required, the fastening device 2 is moved along the connecting rod 1 to the best fixing position, and the positioning scale on the connecting rod 1 is used for precise adjustment, and the position of the fastening device 2 is fixed by the locking mechanism 3 .

[0063] The handheld end of the blood vessel clamp clamping the blood vessel is aligned with the insertion port 221 of the fastening portion 22 to prepare for insertion.

[0064] The fastening bolt 223 is manually tightened to fix the handheld end of the blood vessel clamp.

[0065] After the vascular clips on both sides of the blood vessel are fixed, the vascular anastomosis surgery is performed. Using the stability provided by the fixator, the blood vessel ends are accurately sutured or otherwise anastomosed.

[0066] After the operation is completed, the handheld end of the vascular clamp is released by loosening the fastening bolt 223, and then the fixture is removed from the operation area.

[0067] As is known by common technical knowledge, the present utility model can be implemented by embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present utility model or within the scope equivalent to the present utility model are encompassed by the present utility model.
