Description

Technical Field

[0001] This invention relates to the field of medical suture needle technology, and in particular to a self-dissolving suture needle device for lumbar discectomy. Background Technology

[0002] Lumbar discectomy is a common surgical procedure for treating conditions such as lumbar disc herniation. During the surgery, deep tissue suturing is often required to maintain the height and stability of the intervertebral space or to manage the annulus fibrosus incision. Traditional suturing methods often use straight or curved needles with non-absorbable sutures.

[0003] However, traditional suture needles have significant limitations in the specific deep and narrow operating space of lumbar discectomy: First, straight needles or standard curved needles require a large operating space to complete the needle threading action, which is difficult to achieve in the anatomically complex spinal region, and repeated operations can easily cause damage to surrounding nerves and tissues; second, after the operation, the suture needle usually needs to be removed from the body, which carries the risk of needle dislodgement or breakage, and the needle removal operation itself increases the operation time and the possibility of secondary trauma. In addition, if non-absorbable sutures are used, their long-term presence in the body as foreign bodies may cause complications such as chronic inflammatory reactions, tissue adhesions, or rejection reactions. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the above-mentioned background art, and to propose a self-dissolving suture needle device for lumbar discectomy.

[0005] The technical problem to be solved by the present invention is to provide a self-dissolving suture needle device for lumbar discectomy to solve the problem of inconvenience in the use of existing devices.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A self-dissolving suture needle device for lumbar discectomy includes: an installation device, on which multiple needle bodies are installed, the needle bodies are arranged in a "U" shape, and needle tips are fixedly installed at both ends of the needle bodies, and two threading grooves are opened on the needle bodies, with sutures inserted into the inner cavities of the two threading grooves.

[0007] Preferably, the installation device includes an installation plate with multiple horizontal grooves. Each horizontal groove has a movable block slidably connected to its inner cavity. A horizontal rod is slidably connected through the movable block. The horizontal rod is fixedly connected to the inner wall of the horizontal groove, and a spring is movably installed on the outer side of the horizontal rod. The spring is fixedly connected between the movable block and the inner wall of the horizontal groove. A handle is fixedly connected to the top of the multiple movable blocks on the same side, and a clamp is fixedly connected to the bottom of each of the multiple movable blocks. The needle body is installed between two adjacent clamps.

[0008] Preferably, the ends of both needles are beveled, and the end sections of both needles are pointed.

[0009] Preferably, the outer wall of the needle is provided with multiple sets of grooves.

[0010] Preferably, the multiple sets of grooves are distributed at equal intervals along the axial direction of the needle body.

[0011] Preferably, the inner diameter of the threading groove is larger than the outer diameter of the suture.

[0012] Preferably, the needle body, needle tip, and suture are all made of medical-grade soluble materials.

[0013] Preferably, multiple barb structures are fixedly installed on the inclined surfaces of both needles.

[0014] In the above solution, by setting the needle body as a pre-formed "U" shape and setting needles at both ends of the body, it can complete the penetration of deep tissues and the guidance of sutures in one go. The needle body, needles and sutures are all made of medical soluble materials.

Therefore, they should not be construed as limitations on this invention.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The self-dissolving suture needle device for lumbar discectomy is shown in the embodiment of the present invention, comprising: an installation device, wherein a plurality of needle bodies 1 are installed on the installation device, the needle bodies 1 are arranged in a "U" shape, and needle tips 2 are fixedly installed at both ends of the needle bodies 1, and two thread grooves 3 are opened on the needle bodies 1, and sutures 4 are inserted into the inner cavity of the two thread grooves 3.

[0021] Specifically, in use, the two sutures 4 are passed through the two thread grooves 3 respectively, and then force is applied to the two sutures 4 respectively, so that the sutures 4 pull the needle body 1 to the needle foot and bend it at an angle. At this time, the needle tip 2 is completely embedded in the patient's fibrous tissue, achieving the purpose of fastening the fibers. Then the sutures 4 are cut, and the above operation is repeated to complete the subsequent suturing.

[0022] In this embodiment, as Figures 4-6As shown: The installation device includes an installation plate 7, on which multiple horizontal grooves 9 are provided. Each of the multiple horizontal grooves 9 has a movable block 10 slidably connected to its inner cavity. A horizontal rod 12 is slidably connected through the movable block 10. The horizontal rod 12 is fixedly connected to the inner wall of the horizontal groove 9, and a spring 13 is movably installed on the outer side of the horizontal rod 12. The spring 13 is fixedly connected between the movable block 10 and the inner wall of the horizontal groove 9. A handle 8 is fixedly connected to the top of the multiple movable blocks 10 on the same side, and a clamp 11 is fixedly connected to the bottom of the multiple movable blocks 10. The needle body 1 is installed between two adjacent clamps 11.

[0023] Specifically, firstly, multiple needles 1 are placed between two clamps 11. After all needles 1 are placed, the two handles 8 are squeezed, causing the two handles 8 to move the corresponding multiple movable blocks 10. While the multiple movable blocks 10 stretch the corresponding springs 13, they also move the corresponding clamps 11. The needles 1 are clamped and positioned using the two adjacent clamps 11. After all needles 1 are simultaneously inserted into the sew position, the two handles 8 are released, allowing the multiple clamps 11 to reset under the elastic force of the corresponding springs 13. At this time, the multiple needles 1 are simultaneously separated from the mounting device. Then the mounting device can be directly removed, and the sewing operation of multiple needles 1 and suture thread 4 can be performed in sequence. The operation is convenient.

[0024] All components involved in the installation device are made of medical-grade sterile materials.

[0025] In this embodiment, as Figures 1-3 As shown; the ends of both needles 2 are beveled, and the cross-sections of the ends of both needles 2 are pointed.

[0026] Specifically, the above settings make it easier to insert the needle 2, thus improving suturing efficiency.

[0027] In this embodiment, as Figures 1-2 As shown; multiple sets of grooves 5 are provided on the outer wall of the needle body 1.

[0028] Specifically, by setting multiple sets of grooves 5, external anti-slip operation can be provided when medical staff use tools to hold the needle body 1.

[0029] In this embodiment, as Figures 1-2 As shown; multiple sets of grooves 5 are distributed at equal intervals along the axial direction of the needle body 1.

[0030] Specifically, the above settings ensure that the anti-slip effect provided by the anti-slip area is sufficiently uniform and stable.

[0031] In this embodiment, as Figures 1-3 As shown; the inner diameter of the thread groove 3 is set to be larger than the outer diameter of the suture 4.

[0032] Specifically, the above settings enable the suture 4 to pass quickly through the threading groove 3, and different specifications of suture 4 can be inserted into the threading groove 3 according to the actual situation.

[0033] In this embodiment, as Figures 1-3 As shown; the needle body 1, needle tip 2, and suture 4 are all made of medical soluble materials.

[0034] Specifically, the above-mentioned setup allows the entire device to remain in the body after the suturing task is completed, eliminating the need for a second surgery to remove it.

[0035] In this embodiment, as Figure 4 As shown: Multiple barb structures 6 are fixedly installed on the inclined surfaces of both needles 2.

[0036] Specifically, by utilizing the multiple barb structures 6, a strong anti-backlash force can be provided when the needle tip 2 and needle body 1 are embedded in the patient's fibrous tissue, thereby improving stability.

[0037] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0038] The above description is only a preferred embodiment of the present invention.
