Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a supporting device for Achilles tendon suturing. Background Technology

[0002] Currently, the treatment of Achilles tendon ruptures typically relies on surgical suturing and fixation. In existing medical practice, to locate the two ends of the ruptured Achilles tendon, surgeons often need to make a large incision in the upper part of the heel. Because the muscles contract after an Achilles tendon rupture, causing the ruptured tendon to shift, similar to the elasticity of a rubber band, locating the ruptured ends becomes complex and requires a larger surgical incision. This approach not only increases the patient's trauma area but can also lead to larger postoperative scars.

[0003] To reduce surgical trauma and wound size, the hospital currently employs a temporary solution. This method utilizes two main tools: scissors forceps borrowed from the anesthesiology department and a puncture needle. The specific procedure is as follows: First, a small incision is made at the site of tendon rupture. Then, forceps are used to enter the subcutaneous tissue through the small incision, locate the ruptured tendon, and clamp it. Next, a puncture needle is used to penetrate the skin and muscle tissue from the outside, passing through a hole at one end of the forceps, the ruptured tendon, and a hole at the other end, finally exiting through the skin on the other side. While this method effectively reduces the surgical wound, it has certain limitations because the instruments used are not specifically designed for this purpose.

[0004] While this method can reduce surgical incisions to some extent, significant problems remain due to the instruments not being specifically designed for this purpose. One major issue is the wide head of existing forceps, which hinders flexible subcutaneous manipulation and increases the difficulty of the procedure. Furthermore, the traditional puncture needle's tail is integrated with the body and cannot be detached, making it difficult to pass soft sutures through long needles. Typically, the suture only reaches the needle tip, but it shifts when attempting to withdraw the needle, leading to a high failure rate. This problem is particularly pronounced when multiple sutures are needed (each tendon typically requires 3-4 sutures). Utility Model Content

[0005] The purpose of this invention is to provide a matching instrument for Achilles tendon suturing, so as to solve the problems of difficult operation and high failure rate caused by the large and inflexible head of the existing surgical forceps and the non-removable tail end of the puncture needle.

[0006] To achieve the above objectives, a supporting instrument for Achilles tendon suturing is provided, including surgical forceps. The surgical forceps include two rotatably connected clamping arms, each clamping arm having a circular clamping end fixedly connected to its starting end, wherein:

[0007] The ring clamping end is a tapered ring structure, with the beginning of the ring clamping end being narrower than the end.

[0008] It also includes a puncture needle, which comprises a needle tube, wherein:

[0009] The needle tube has a threaded groove at its tail end, and the needle tube is fixedly connected to the connecting block through the threaded groove.

[0010] As a further improvement to this technical solution, the inner side of the circular clamping end is provided with anti-slip texture, and the part of the circular clamping end that connects to the clamping arm is provided with a curved part.

[0011] As a further improvement to this technical solution, a handle is provided at the tail end of the clamping arm.

[0012] As a further improvement to this technical solution, the connecting block has flat disassembly surfaces on both sides.

[0013] As a further improvement to this technical solution, an isolation disc is fixedly connected below the connecting block, and a handle is fixedly connected below the isolation disc.

[0014] As a further improvement to this technical solution, a threading hole is provided inside the handle, and the threading hole gradually enlarges from top to bottom.

[0015] As a further improvement to this technical solution, the needle tube is hollow inside and connected to the thread hole.

[0016] As a further improvement to this technical solution, a plug is snapped into the lower part of the handle.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Among the instruments used for Achilles tendon suturing, the surgical forceps feature a tapered ring design at the clamping end, narrower at the beginning than the end. This unique shape significantly reduces resistance when the forceps move subcutaneously, allowing the surgeon to more easily expand and separate tissue. This enables more precise and flexible exploration from the subcutaneous layer to the severed tendon, improving the convenience and accuracy of the surgical procedure and reducing its complexity. Simultaneously, the anti-slip grooves on the inner side of the ring clamping end increase friction with the tendon, providing a more stable grip and effectively preventing slippage during the procedure, further enhancing the safety and reliability of the surgery.

[0019] 2. In this Achilles tendon suturing instrument, the tail end of the puncture needle has a threaded groove for fixed connection with the connecting block. The connecting block has flat disassembly surfaces on both sides, allowing for easy disassembly of the puncture needle tail end. After the suture passes through the puncture needle tail end, the tail end can be disassembled, allowing the needle tip to exit from the other side with the suture, avoiding the problem of suture movement during traditional puncture needle withdrawal and reducing the failure rate. For situations where each tendon typically requires 3-4 sutures, the puncture needle of this invention effectively ensures multiple sutures pass smoothly through the tendon, improving the surgical success rate.

[0028] Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a set of instruments for Achilles tendon suturing, including surgical forceps 1 and puncture needle 2.

[0029] like Figure 1 and Figure 3 As shown, the surgical forceps 1 consists of two rotatably connected clamping arms 11. The starting end of each clamping arm 11 is fixedly connected to a circular clamping end 13, which is a tapered circular structure with the starting end narrower than the tail end. This design significantly reduces the resistance when the surgical forceps 1 moves subcutaneously, making it easier for doctors to expand and separate tissues. It also enables more precise and flexible exploration from the subcutaneous tissue to the severed tendon, improving the convenience and accuracy of the surgical operation and reducing the difficulty of the surgery.

[0030] The inner side of the circular clamping end 13 is provided with anti-slip grooves 14, which increases the friction between the clamping end and the tendon, making the clamping of the tendon more stable and effectively preventing the tendon from slipping during operation, thus further improving the safety and reliability of the surgery. In addition, the part of the circular clamping end 13 that connects to the clamping arm 11 has a curved part 15, which allows the surgical forceps 1 to have better flexibility and maneuverability in complex anatomical environments, and can better adapt to different surgical needs.

[0031] The clamping arm 11 is equipped with a handle 12 at its end, which is convenient for doctors to hold and operate. The handle 12 should be designed in accordance with ergonomic principles so that doctors can maintain a comfortable operating experience during long-term surgery.

[0032] like Figure 1 and Figure 2As shown, the puncture needle 2 includes a needle tube 21. A threaded groove is formed at the tail of the needle tube 21, and it is fixedly connected to a connecting block 22 via this groove. The connecting block 22 has internal threads for fixed connection with the threaded groove at the tail of the needle tube 21. An isolation plate 23 is fixedly connected below the connecting block 22, and a handle 24 is fixedly connected below the isolation plate 23. The isolation plate 23 is also fixedly connected above the handle 24 to prevent the suture from getting tangled in other parts during operation. A threading hole 241 is formed inside the handle 24, gradually widening from top to bottom to facilitate smooth suture passage. The needle tube 21 is hollow and connects to the threading hole 241, ensuring the suture can pass smoothly through the entire needle tube 21. A plug 25 is engaged below the handle 24 to seal the threading hole 241 and prevent accidental suture dislodgement.

[0033] The connecting block 22 has flat disassembly surfaces 221 on both sides, which allows the tail end of the puncture needle 2 to be easily disassembled. After the suture passes through the tail end of the puncture needle 2, the tail end can be disassembled, and the needle can then pass out from the other side with the suture, reducing the failure rate of the operation.

[0034] Working principle: In actual surgical procedures, a small incision is first made at the site of tendon rupture. Then, surgical forceps 1 are used to enter the subcutaneous tissue through the small incision to locate and clamp the ruptured tendon. Because the circular clamping end 13 of surgical forceps 1 is designed with a tapered ring structure and has anti-slip grooves 14 on the inner side, this not only makes the surgical forceps 1 more flexible in its movement under the skin but also increases the stability of the clamping, reducing the risk of tendon slippage. The presence of the curved portion 15 further enhances the flexibility and maneuverability of surgical forceps 1 in complex anatomical environments, allowing the surgeon to more accurately locate and manipulate the tendons.

[0035] Next, using puncture needle 2, the needle is inserted through the skin and muscle tissue from the outside, passing through the hole at one end of the forceps, the ruptured tendon, and the hole at the other end, finally exiting through the skin on the other side. At this point, the tail end of puncture needle 2 is detached, and the needle tip, carrying the suture, exits from the other side, avoiding the problem of the suture moving when the traditional puncture needle is withdrawn.

[0036] Subsequently, the surgical forceps 1 are removed from the small incision, bringing out the sutures, and the tendon on one side is sutured. The other tendon is sutured in the same way, and finally the sutures at both ends of the tendon are tied together to anastomose the tendons.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
