Description

Technical Field

[0001] This utility model relates to the field of vascular suture technology. Specifically, it is a vascular suture clamping connector. Background Technology

[0002] Vascular suturing is a crucial step in surgery. Both the speed and the quality of suturing directly impact the surgical time and postoperative condition. Manual suturing relies entirely on the skill of medical staff. Due to the flexible structure of blood vessels and the difficulty in positioning them, it requires a high level of expertise and wastes a significant amount of time, thus prolonging the surgical period. Therefore, there is a need for a method that can reduce the difficulty of vascular suturing and quickly locate the sutured vascular connection points, thereby enabling rapid suturing and reducing both surgical time and difficulty. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a vascular suture clamp connector that can quickly locate blood vessels at the suture site and reduce the difficulty of suture.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A vascular suture clamping connector includes a first clamping arm and a second clamping arm rotatably connected at their lower ends. Vascular sleeves are fixedly connected to the upper ends of the first and second clamping arms, respectively. The vascular sleeves are arranged perpendicularly to their corresponding first and second clamping arms. Movable sleeves are slidably connected to the vascular sleeves. Openings for blood vessels to enter and exit and to pass through along the axis are respectively provided at corresponding positions on the vascular sleeves and the movable sleeves. Multiple circumferentially distributed spreading claws are rotatably connected to the movable sleeves. The protruding ends of each spreading claw extend towards the contact side of the first and second clamping arms, and each spreading claw has a hook extending inward. Multiple guide rails are evenly distributed around the outer circumference of the vascular sleeve. The outer sides of each spreading claw are rotatably and slidably connected to the corresponding guide rails. A pressing rod for driving the movable sleeve to slide along the vascular sleeve is rotatably connected to the first and second clamping arms.

[0006] Preferably, the pressing rod has a rotating rod in the middle that is rotatably connected to the corresponding first clamping arm and second clamping arm, and the rotating rod has a torsion spring corresponding to the first clamping arm and second clamping arm.

[0007] Preferably, the inner sides of the first clamping arm and the second clamping arm are connected by a pressing spring.

[0008] Preferably, the spring force of the pressing spring is greater than that of the torsion spring.

[0009] Preferably, a check rod is rotatably connected to the first clamping arm, and a mating groove is provided on the second clamping arm to cooperate with the check rod. The extended end of the check rod passes through the mating groove on the second clamping arm. The check rod is provided with a plurality of check plates extending obliquely inward, and a mating plate that cooperates with the check plates is provided inside the mating groove.

[0010] Preferably, the extended end of the check rod is fixedly connected to a lever for actuating the check rod.

[0011] Preferably, the end of the pressing rod connected to the moving sleeve is provided with a connecting rod, and a mating groove is opened on the moving sleeve at the position corresponding to the connecting rod, and the connecting rod rotates and slides in the mating groove.

[0012] Preferably, the guide rails are evenly distributed around the circumference of the blood vessel sleeve, and the guide rails have an arc-shaped structure.

[0013] Preferably, the middle part of the spreading claw is rotatably connected to the moving sleeve, and the outer side of each spreading claw is respectively engaged with the guide rail.

[0014] Preferably, the openings on the blood vessel sleeve and the movement sleeve are located at the ends away from the rotatable connection between the first clamping arm and the second clamping arm, and the width of the opening matches the width between the adjacent spreading claws.

[0015] The technical solution of this utility model has achieved the following beneficial technical effects:

[0016] 1. It enables blood vessels to quickly enter and exit the vascular sleeve, and achieves positioning and traction within the vascular sleeve;

[0017] 2. The sliding sleeve on the vascular sleeve moves relative to the vascular sleeve, so that the vascular sleeve opens the connection position of the vascular vessel without changing the position of the vascular sleeve on the vascular vessel.

[0018] 3. The vessel wall at the connection point of the blood vessel is grasped by multiple evenly distributed circumferential claws on the moving sleeve, and then the area to be sutured is opened and positioned by unfolding the claws.

[0019] 4. By positioning the blood vessel connection points and pressing them together, the position can be prevented from changing during the suturing process;

[0020] 5. During vascular suturing, the pressure level is positioned using a check rod to avoid the need for additional hand to apply constant force during suturing;

[0021] 6. The spring force of the torsion spring is less than that of the compression spring, so that the force applied by the hand during the pressing process will first open the claws before they move closer together. Attached Figure Description

Detailed Implementation

[0030] In this embodiment, the main structure includes two clamping arms, namely a first clamping arm 1 and a second clamping arm 2. The lower ends of the first clamping arm 1 and the second clamping arm 2 are rotatably connected. The upper ends of the first clamping arm 1 and the second clamping arm 2 are respectively fixedly connected with blood vessel sleeves 3 arranged perpendicular to the corresponding first clamping arm 1 or second clamping arm 2. The function of the blood vessel sleeve 3 is to fit over the outside of the blood vessel to be connected. An outlet for blood vessel entry is opened on the end of the blood vessel sleeve 3 away from the corresponding clamping arm. In the initial state of connection, the blood vessel is flat due to its relatively soft characteristics, so that the blood vessel can easily pass through the outlet and enter the blood vessel sleeve 3. The two blood vessel sleeves 3 are respectively slidably connected with moving sleeves 4 along the axis of the blood vessel sleeve 3. The moving sleeves 4 are also provided with openings 5 ​​corresponding to the positions of the openings 5, so as to avoid the moving sleeves 4 affecting the entry and exit of the blood vessels. Multiple spreading claws 6 are rotatably connected to the moving sleeves 4. The rotation axis of each spreading claw 6 is perpendicular to the axis of the blood vessel sleeve 3 and is staggered. Each spreading claw 6 is evenly distributed on the circumference of the moving sleeve 4.

[0031] The spreading claw 6 is rotatably connected to the moving sleeve 4 in the middle. The posture of the spreading claw 6 is changed by changing the position of the moving sleeve 4. The spreading claw 6 is divided into inner and outer parts by the rotatable connection in the middle. The inner part extends parallel to the axis of the blood vessel sleeve 3 and toward the direction between the two clamping arms. The end of the inner extension is fixedly connected to a hook 7. The bending direction of the hook 7 is toward the axis of the blood vessel sleeve 3. The outer part of the spreading claw 6 extends obliquely outward away from the axis of the blood vessel sleeve 3. Multiple guide rails 8 are fixedly connected to the blood vessel sleeve 3 to guide the outer extension of the spreading claw 6. The end of the outer extension of the spreading claw 6 is rotatably and slidably connected to the corresponding guide rail 8. The guide rail 8 has an arc-shaped structure. One end of the guide rail 8 is fixedly connected to the outside of the blood vessel sleeve 3 and the other end extends obliquely outward. The extension direction of the guide rail 8 is toward the direction between the two spreading claws 6. The spreading action of the spreading claw 6 is driven by the moving sleeve 4.

[0032] In its initial state, the inner side of the spreading claw 6 is parallel to the axis of the blood vessel sleeve 3. At this time, the blood vessel to be connected is inserted into the blood vessel sleeve 3 through the opening 5. The connection part of the blood vessel corresponds to the position of the hook 7 on the inner side of the spreading claw 6. Then, the end of the hook 7 is extended to the inner side of the end of the blood vessel to be connected. Then, the moving sleeve 4 is controlled to slide relative to the blood vessel sleeve 3. The outer end of the spreading claw 6 moves along the guide rail 8. When the moving sleeve 4 slides along the blood vessel sleeve 3, it controls the hook 7 to pull the end of the blood vessel and uses the elasticity of the blood vessel to perform a certain spreading action. After the ends of the two blood vessels to be connected are spread open and brought closer to each other, the outer sides of the connection part are pressed together by the blood vessel sleeve 3 after the blood vessels are spread open. At this time, the spreading and positioning of the blood vessel is completed. Then, the suturing operation is performed on the blood vessel. Since the connection part of the blood vessel is spread open and fixed together, the suturing difficulty is reduced.

[0033] The first clamping arm 1 and the second clamping arm 2 are respectively rotatably connected to pressing rods 9 for driving the moving sleeve 4. The middle part of the pressing rod 9 is rotatably connected to the corresponding first clamping arm 1 or second clamping arm 2 via a rotating rod. The rotating rod and the corresponding clamping arm are connected by a torsion spring 10. The end of the pressing rod 9 connected to the moving sleeve 4 is provided with a connecting rod. The moving sleeve 4 is provided with a mating groove 17 that cooperates with the connecting rod. The connecting rod on the rotating rod rotates and slides in the mating groove 17. The end of the rotating rod away from the moving sleeve 4 is the hand pressing area. By manually pressing to overcome the elastic force of the torsion spring 10, the rotating rod is driven to rotate, thereby controlling the movement of the moving sleeve 4 and opening the blood vessel connection site.

[0034] The first clamping arm 1 and the second clamping arm 2 are connected by a pressing spring 11. The elastic force of the pressing spring 11 is greater than that of the torsion spring 10. When the hand presses on the outside of the pressing rod 9, the pressing rod 9 will be pressed to a certain position first, and then the pressing spring 11 will be overcome to move. This completes the process of first opening up the end of the blood vessel and then squeezing and positioning it together, which facilitates the subsequent suturing action.

[0035] A check rod 12 is rotatably connected to the first clamping arm 1 near its center. The extended end of the check rod 12 extends toward the second clamping arm 2. A corresponding groove 13 is provided on the second clamping arm 2 for the first clamping arm 1 to pass through. A check plate 14 extending obliquely is fixedly connected to the check rod 12. A matching plate 15 that mates with the check plate 14 is provided in the groove 13. When the first clamping arm 1 and the second clamping arm 2 approach each other, the check plate 14 passes through the groove 13. When the hand is released, the obliquely arranged check plate 14 and the matching plate 15 play a reverse blocking role, thereby completing the positioning and saving effort during use, and further improving the stability of the connection. When it is necessary to release, the actuating plate 16 located at the extended end of the check rod 12 is moved to disengage the check plate 14 from the matching plate 15. At this time, the hand is released, and the two clamping arms will return to their original position under the elastic force of the pressing spring 11.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
