Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a surgical instrument for meniscus injury suturing. Background Art

[0002] The meniscus is a semilunar cartilage located between the femur and tibia of the knee joint. Its edges are thicker and closely connected to the joint capsule, while the center is thinner and free. A normal meniscus increases the concavity of the tibial condyle and cushions the medial and lateral condyles of the femur to increase the stability of the joint and to act as a buffer and shock absorber.

[0003] Meniscus injury is one of the common sports injuries, and it often occurs in people who exercise excessively and do heavy physical labor. Common meniscus injuries are meniscus tears caused by twisting external force, which manifests as severe knee pain, joint swelling, and limited movement. Meniscus suture is currently the most ideal surgical method for treating meniscus injuries.

[0004] However, the existing meniscus suturing devices are complex in structure, expensive in cost, and inconvenient to operate. Therefore, we propose a meniscus injury suturing surgical instrument. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a technical solution for a meniscus injury suture surgical instrument:

[0022] Embodiment:

[0023] As Figure 1 shown, the meniscus injury suture surgical instrument of this technical solution mainly consists of a handle 2 for the doctor to hold the instrument by hand and a thread holding rod 1 to form a hook needle 3. The handle 2 is fixedly installed at the right end position of the thread holding rod 1, and the hook needle 3 is inserted into the inner cavity of the handle 2 in a penetrating manner.

[0024] Wherein, the left end of the crochet hook 3 sequentially penetrates through the handle 2 and the thread holding rod 1 and extends to the outside of the left side of the thread holding rod 1.

[0025] Wherein, as Figure 2 shown, a lead head 5 is fixedly installed at the left end position of the thread holding rod 1.

[0026] Wherein, a lead groove 13 for the suture 4 to pass through is formed at the top of the lead head 5, and a thread holding rod head end hole 6 is formed inside the hook head of the lead head 5.

[0027] Wherein, as Figure 2 shown, a hook head 7 is provided at the left end of the crochet hook 3, and a crochet hook groove 8 is formed at the bottom position of the hook head 7.

[0028] Wherein, as Figure 3 shown, a thread clamping groove 9 is formed at the left side position of the top of the handle 2, and the suture 4 is clamped in the inner cavity of the thread clamping groove 9.

[0029] Wherein, the left end of the suture 4 passes through the lead groove 13 on the lead head 5 and passes out from the thread holding rod head end hole 6.

[0030] Wherein, a puncture crochet hook pull handle 10 is fixedly connected to the right end of the crochet hook 3, and a rubber ring 11 is fixedly bonded in the inner ring of the puncture crochet hook pull handle 10, and an anti-slip groove 12 is provided on the outer wall of the handle 2. The main function of the puncture crochet hook pull handle 10 is to allow the doctor to pull the crochet hook 3 back and forth with the fingers, and the main functions of the rubber ring 11 and the anti-slip groove 12 are to increase the friction with the doctor's fingers and palm, and avoid slippage during the operation and cause medical accidents.

[0031] In this embodiment, the process of using the surgical instrument of the present technical solution is as follows:

[0032] Pre-hang the suture 4 on the thread holding rod 1, so that the left end of the suture 4 passes through the lead groove 13 on the lead head 5 and passes out from the thread holding rod head end hole 6, and is horizontally placed in the center of the thread holding rod head end hole 6. Then the doctor operates the surgical instrument to place the thread holding rod 1 holding the suture 4 on the edge of the meniscus, press and reset it downward through the handle 2, and then push the puncture crochet hook 3 to make the hook head end 7 pass through the meniscus tissue and pass through the center of the thread holding rod head end hole 6. Then pull the puncture crochet hook pull handle 10 in the reverse direction to perform the action of withdrawing the puncture crochet hook 3, hook the suture 4 through the crochet hook groove 8, and then as the puncture crochet hook 3 is withdrawn, until the suture 4 is pulled out of the body, and finally complete the knotting action of the suture 4 outside the body, push the suture knot to the suture site to tighten, and complete one-time suture passing.

[0033] This technical solution needs to be used in the meniscus injury suture repair surgery technique under arthroscopic surgery. First of all, the overall structure is relatively very simple, without excessive design of expensive materials and structures. On the one hand, there will be no problem of easy damage due to excessive structures. On the other hand, the cost is well controlled, which is conducive to promotion and popularization, reducing the treatment cost. The most important thing is that the operation is simpler and faster.
