Technical Field
[0001] This application relates to the technical field of medical devices, and particularly to a suture - attached double - anchor implant system and an implantation method. Background Art
[0002] In the field of medical surgery, especially for rotator cuff repair surgery, internal row nails and external row nails are commonly used fixation tools. The internal row nails are mainly used to provide stable support points inside the bone to facilitate suturing damaged tissues, while the external row nails ensure the firmness of the suture through interface screws. In recent years, with the development of minimally invasive surgery technology, suture - attached anchors have gradually gained favor in clinical applications due to their simple operation and less trauma.
[0003] Currently, in order to fix the rotator cuff on the humerus, doctors usually drill two bottom holes in the bone and then sequentially implant two suture - attached anchors. This process involves multiple steps, including drilling, implanting the first anchor, drilling the second hole, and implanting the second anchor. In addition, special tools are required to adjust and fix the position of each anchor to ensure its accurate embedding in the predetermined position.
[0004] However, this traditional suture - attached anchor implantation method still has some deficiencies. Its implantation method mainly relies on manual sequential implantation, which not only increases the surgical time and complexity but also may cause increased pain to the patient and excessive physical exertion for the doctor due to multiple operations. Especially in cases where precise control of the anchor position is required, this method is prone to errors, thus affecting the overall surgical effect. Therefore, how to improve the efficiency and accuracy of suture - attached anchor implantation has become an urgent technical problem to be solved. Summary of the Invention
[0005] To overcome the deficiencies of the above - mentioned prior art, this application provides a suture - attached double - anchor implant system and an implantation method. By using an adjustable double - metal rod, two suture - attached anchors can be implanted simultaneously, significantly improving the surgical efficiency and reducing the pain of the patient and the physical burden on the doctor.

Specifically, the design of the fixed push rod and the movable push rod allows the doctor to place the two anchors above two bottom holes respectively in one action, thus reducing the time for multiple adjustments and implantations, significantly improving the overall efficiency of the operation. Shortening the operation time means that the discomfort of the patient during the operation is reduced, which helps the rapid recovery after the operation and can effectively reduce the pain of the patient; by simplifying the implantation steps, the operation of the doctor is more convenient, reducing the physical consumption caused by long - term surgery, improving the safety and success rate of the operation; the coordinated action of the opening and closing mechanism and the locking mechanism ensures that the anchor on the fixed push rod can be separated from the anchor on the movable push rod at an accurate position, ensuring the accuracy of the anchor implantation.

This design enables the operator to easily control the movement of the push block through the pressing block, so as to achieve the precise rotation and locking of the movable metal rod, improving the stability and reliability of the system. At the same time, the engagement of the serrated portion and the serrated groove ensures the fixed position of the movable metal rod, avoiding dislocation caused by accidents during the operation, and further improving the safety of the operation.
[0022] Optionally, scale lines are provided on the side of the limiting groove; a hand guard is provided at the front section of the handle, and a wire winding groove is provided on the hand guard.
[0023] By adopting the above technical solution, the scale lines provided on the side of the limiting groove can accurately indicate the relative position between the movable push rod and the fixed push rod, thereby improving the accuracy and consistency of anchor bolt implantation. The design of the hand guard and its wire winding groove provided at the front section of the handle helps to protect the suture from external damage, and at the same time facilitates the operation and management of the suture during the operation, further improving the safety and convenience of the operation.

This design can confine the suture in the lumen, reducing the interference of the suture to the surgery. It not only simplifies the installation and adjustment process of the suture, improves the convenience of operation, but also enhances the stability and reliability of the system, reduces the possible accidents during the surgery, thereby further improving the safety and success rate of the surgery.

[0029] By adopting the above technical solution, a knocking stop piece is fixed at the tail end of the fixed push rod, and the movable push rod is rotatably connected in the knocking stop piece, which can effectively improve the operation convenience and stability during the implantation of the anchor. Specifically, the design of the knocking stop piece enables the doctor to quickly and accurately complete the implantation action of the anchor by knocking the tail of the handle without the assistance of complex tools, simplifies the surgical steps, and improves the surgical efficiency; the rotational connection design of the movable push rod and the knocking stop piece ensures the structural stability of the whole system during the process of pushing and rotating the movable push rod, avoiding the deviation or damage of the anchor caused by improper operation, thus ensuring the safety and success rate of the surgery.

[0065] Specifically, referring to Figures 4 - 5 , the anchor 7 can be made of stainless steel. A number of ratchet bosses are arranged at intervals on the outer wall. And in order not to affect the suture 9 when the anchor 7 is inserted into the bone hole, a wire - releasing groove 72 is arranged along the length direction on the outer wall of the anchor 7. And in order to facilitate the fixation of the suture 9, a wire hole 73 is provided at the head of the anchor 7; the connecting portion 71 at the tail of the anchor 7 can adopt the positioning structure form of a regular polygon groove.

Embodiment Two
[0072] Referring to Figures 15 - 16 , the difference between this embodiment and Embodiment One is that the push block 4 includes a guiding block 44 and a pressing block 45 slidably connected above the guiding block 44. Among them, a guiding groove 441 is provided at the upper end of the guiding block 44, and a guiding block 453 adapted to the guiding groove 441 is provided at the lower end of the pressing block 45.

[0073] The implementation principle of this embodiment is as follows: This design enables the operator to easily control the movement of the push block 4 through the pressing block 45, thereby achieving the precise rotation and locking of the movable metal rod, improving the stability and reliability of the system. At the same time, the engagement between the serrated portion 452 and the serrated groove 111 ensures the fixed position of the movable metal rod, avoiding dislocation caused by accidents during the operation, and further enhancing the safety of the operation.

[0075] The implementation principle of this embodiment is as follows: The fixed push rod 2 and the movable push rod 3 are in a tubular structure, and an opening groove 212 is provided at the tail, enabling the suture 9 to pass through the lumen and be led out from the opening groove 212. This design can confine the suture 9 in the lumen, reducing the interference of the suture 9 on the operation. It not only simplifies the installation and adjustment process of the suture 9, improves the convenience of operation, but also enhances the stability and reliability of the system, reduces possible accidents during the operation, and thus further improves the safety and success rate of the operation.
