Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a fibrous annulus suture clamp for minimally invasive surgery of intervertebral disc herniation. Background Technology
[0002] Minimally invasive lumbar disc herniation surgery utilizes modern high-tech surgical equipment and methods to minimize the risk of infection by causing minimal trauma to the lumbar disc herniation. It is a new treatment method with less trauma, less pain, and better results. Lumbar annulus fibrosus suture refers to suturing the annulus fibrosus during lumbar minimally invasive surgery. Lumbar annulus fibrosus suture is suitable for all patients with disc herniation who need nucleus pulposus removal surgery.
[0003] The existing technical solutions mentioned above have the following drawbacks: the existing annulus fibrosus lacks auxiliary clamping instruments during suturing, making it impossible to accurately clamp the area to be sutured, increasing the operation time and reducing the efficiency of the operation. Utility Model Content
[0004] The purpose of this invention is to provide a fibrous annulus suture holder for minimally invasive surgery of intervertebral disc herniation.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A fibrous annulus suture clamp for minimally invasive surgery of intervertebral disc herniation includes a first clamp body, a first handle fixedly connected to one end of the outer side of the first clamp body, a support block fixedly connected to the other end of the outer side of the first clamp body, a first threaded hole opened inside the support block, an extension rod provided on the outer side of the support block, an external thread provided at one end of the outer side of the extension rod, and a clamping head fixedly connected to the other end of the outer side of the extension rod.
[0007] By adopting the above technical solution, by adding an extension rod to the outside of the first clamp body, the length of the clamping structure can be extended to facilitate the operation. The device can be extended into the patient's body, and the clamping head can be used to clamp the ruptured annulus fibrosus for easy suturing.
[0008] Furthermore, a slot is provided on the outer side of the clamping head, a clamping block is provided inside the slot, a screw is inserted into the inside of the clamping head, and a second threaded hole is provided inside the clamping block.
[0009] By adopting the above technical solution and adding a detachable clamping block to the outside of the clamping head, the clamping block can better clamp the two ends of the broken fiber ring, and can be replaced at any time for convenient use.
[0010] Furthermore, a second clamp body is provided on the outside of the first clamp body, a second handle is fixedly connected to one end of the outside of the second clamp body, and the same support block is fixedly connected to the other end of the outside of the second clamp body. A spring is provided between the first handle and the second handle.
[0011] By adopting the above technical solution, by adding two sets of clamps and adding a spring between the two sets of clamps, when the device is clamped with force, the clamping heads at both ends open at an angle. After the hand is released, the clamping heads at both ends will quickly clamp the two ends of the annulus fibrosus due to the extension and contraction of the spring. It can be clamped even without the fingers, which facilitates the doctor's surgical operation.
[0012] Furthermore, the first threaded hole and the external thread are threadedly connected, the slot and the clamping block are engaged, the screw extends through the clamping head into the interior of the clamping block, and the screw and the second threaded hole are threadedly connected.
[0013] By adopting the above technical solution, the extension rod can also be installed by threaded connection, which can be replaced at any time, making it convenient to operate and use.
[0014] Furthermore, one end of the outer side of the spring is fixedly connected to the outer side of the first clamp body, and the other end of the outer side of the spring is fixedly connected to the outer side of the second clamp body. The first clamp body is engaged inside the second clamp body and is rotatably connected to the second clamp body via a pivot pin.
[0015] By adopting the above technical solution, the spring allows the clamping device to increase the angle of the clamping heads at both ends when subjected to finger force, and decrease the angle after the finger is withdrawn, so that the ruptured position of the annulus fibrosus can be quickly clamped, facilitating the surgical suturing operation.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] It employs a first clamp, a second clamp, a spring, an extension rod, and a clamping block. The first and second clamps can quickly rebound due to the extension and retraction of the spring. By forcefully opening the two clamps with a finger and withdrawing the finger, the two clamps quickly close, clamping the area to be sutured for easy stitching. At the same time, the extension rod and clamping block can be locked in place by threaded connection, making it easy to replace in case of future damage. In addition, the extension rod can be selected with an appropriate length according to actual use needs, resulting in a convenient and easy-to-use effect. Attached Figure Description

[0024] Reference Figure 1-4 A fibrous annulus fibrosus suture clamp for minimally invasive surgery of intervertebral disc herniation includes a first clamp body 1. A first handle 2 is fixedly connected to one end of the outer side of the first clamp body 1. A support block 3 is fixedly connected to the other end of the outer side of the first clamp body 1. A first threaded hole 4 is opened inside the support block 3. An extension rod 5 is provided on the outer side of the support block 3. An external thread 6 is provided at one end of the outer side of the extension rod 5. A clamping head 7 is fixedly connected to the other end of the outer side of the extension rod 5. A slot 8 is reserved on the outer side of the clamping head 7. A clamping block 9 is provided inside the slot 8. A screw 10 is inserted into the inside of the clamping head 7. A second threaded hole 11 is opened inside the clamping block 9. A second clamp body 12 is provided on the outer side of the first clamp body 1. A second handle 13 is fixedly connected to one end of the outer side of the second clamp body 12. A similar handle 13 is fixedly connected to the other end of the outer side of the second clamp body 12. A spring 14 is provided between the support block 3, the first handle 2, and the second handle 13. An extension rod 5 is added to the outside of the first clamping body 1. By extending the length of the clamping structure, the operation can be facilitated, and the device can be extended into the patient's body. The clamping head 7 clamps the ruptured annulus fibrosus, facilitating suturing. At the same time, a detachable clamping block 9 is added to the outside of the clamping head 7. The clamping block 9 can better clamp the two ends of the ruptured annulus fibrosus and can be replaced at any time. In addition, a spring 14 is added between the two sets of clamping bodies. When the device is clamped with force, the clamping heads 7 at both ends open at an angle. After the hand is released, the clamping heads 7 at both ends will quickly clamp the two ends of the annulus fibrosus due to the extension and contraction of the spring 14. It can also be clamped without the fingers, which facilitates the doctor's surgical operation.
[0025] like Figure 1-4As shown, the first threaded hole 4 and the external thread 6 are threadedly connected, the slot 8 and the clamping block 9 are engaged, the screw 10 passes through the clamping head 7 and extends into the interior of the clamping block 9, the screw 10 and the second threaded hole 11 are threadedly connected, one end of the outer side of the spring 14 is fixedly connected to the outer side of the first clamp body 1, the other end of the outer side of the spring 14 is fixedly connected to the outer side of the second clamp body 12, the first clamp body 1 is engaged inside the second clamp body 12, and is rotatably connected to the second clamp body 12 by a pivot pin. The extension rod 5 and the clamping block 9 can be installed by threaded connection and can be replaced at any time.
[0026] The implementation principle of this embodiment is as follows: When in use, first select an extension rod 5 of appropriate length according to the needs of the surgery, and install it through the threaded connection between the external thread 6 and the first threaded hole 4. Then, extend the device to the vicinity of the annulus fibrosus in the patient's body. After that, put your finger through the handle and forcefully open the two sets of extension rods 5. Then, bring the clamping head 7 close to the position of the annulus fibrosus rupture. Then, slowly release the handle. The two sets of clamps are quickly closed by the extension and contraction of the spring 14, clamping the two ends of the annulus fibrosus rupture. Then, start suturing at this position. This makes it convenient for doctors to operate. At the same time, the extension rod 5 and the clamping block 9 can be disassembled by the thread, which is convenient for later replacement.
