Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a disposable fiber ring suture device. Background Art

[0002] Intervertebral disc herniation is one of the common diseases in the middle-aged and elderly, and the number of patients has been on the rise in recent years. The most common cause of this disease is that the various parts of the intervertebral disc, such as the nucleus pulposus, annulus fibrosus and cartilage plate, especially the nucleus pulposus, have degenerative changes to varying degrees. Under the action of external factors, the annulus fibrosus of the intervertebral disc ruptures, and the nucleus pulposus tissue protrudes from the ruptured part to the back or into the spinal canal, causing adjacent nerve roots to be stimulated or compressed, resulting in a series of clinical symptoms such as pain, limb numbness, and pain. In addition, the intervertebral disc gradually lacks blood circulation after adulthood and has poor repair ability. When a certain predisposing factor that can cause a sudden increase in the pressure on the intervertebral disc occurs, the less elastic nucleus pulposus may pass through the less tough annulus fibrosus, causing nucleus pulposus herniation.

[0003] In order to solve the problem of herniated intervertebral disc, surgical treatment is often required. The operation mainly requires nucleus pulposus removal, removal of the protruding nucleus pulposus and free annulus fibrosus tissue to relieve the compression of the nerve roots. The problem is that after the nucleus pulposus removal, the remaining annulus fibrosus incision cannot be handled, and the residual nucleus pulposus is prone to recurrence. Since the simple laminectomy with fenestration has been carried out clinically, it has relieved the pain of countless patients, but the high secondary recurrence rate after the operation still brings great pain to patients. In order to prevent recurrence, the commonly used method now is to repair the annulus fibrosus, which can significantly reduce the recurrence rate after nucleus pulposus removal and effectively reduce the stimulation of inflammatory mediator leakage on the nerve roots.

[0004] The device used for suturing the annulus fibrosus incision after the nucleus pulposus is removed for patients with intervertebral disc herniation recorded in the related art is a disposable annulus fibrosus suture device. Currently, this type of product mainly includes gun-type, knob-type and button-type. For the gun-type product, although the structure is convenient for human operation, the operation process is relatively complicated in design, so it will reduce the efficiency of the operation; for the knob-type product, in order to ensure that the suture can smoothly enter the inside of the annulus fibrosus incision and achieve the purpose of suturing, the knob must be screwed in and out several times, and the process of screwing in and out is not convenient for human operation, thus reducing the efficiency of the operation; for the button-type product, although this product is relatively simple in operation, its design is not convenient for human holding, and the product needs to be manually assembled before the operation. This step greatly increases the risk of product failure rate and may also increase the failure rate of the operation. Therefore, it is an urgent problem to design a device with simple structure, simple operation and no need for manual assembly before the operation. Summary of the invention

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-7 This application is described in further detail.

[0042] The present application embodiment discloses a disposable fiber ring suture device, referring to Figure 1 and Figure 2 The disposable fiber ring suture device comprises a left puncture mechanism 1 and a right puncture mechanism 2, and the left puncture mechanism 1 and the right puncture mechanism 2 are used in coordination.

[0043] Reference Figure 3 and Figure 4 The left puncture mechanism 1 includes a firing assembly 11, a left puncture suture 12 and a left puncture fixture 13. The left puncture suture 12 and the left puncture fixture 13 are connected. The firing assembly 11 is used to deliver the left puncture suture 12 and the left puncture fixture 13 into the fiber ring incision.

[0044] Reference Figure 5 and Figure 6 The right puncture mechanism 2 includes a pushing component 21, a right puncture suture 22 and a right puncture fixture 23. The right puncture suture 22 and the right puncture fixture 23 are connected, and the pushing component 21 is used to deliver the right puncture fixture 23 into the fiber ring incision.

[0045] When performing annulus fibrosus suturing, the staff uses the firing assembly 11 to deliver the left puncture fixture 13 into the annulus fibrosus incision, and then uses the pushing assembly 21 to deliver the right puncture fixture 23 into the annulus fibrosus incision. In this way, the structure of the device is simpler, which correspondingly simplifies the suturing process, facilitates operation, and does not require manual assembly before surgery, thereby improving surgical efficiency.

[0046] Specifically, refer to Figure 3 and Figure 4 The left puncture mechanism 1 also includes a shell 14, a left puncture push rod 15, a left puncture needle 16 and a left puncture top screw 17. The left puncture push rod 15 and the left puncture needle 16 are both hollow tubes. The push rod is penetrated on the shell 14 and connected to the shell 14. The left puncture needle 16 is penetrated in the left puncture push rod 15 and the left puncture needle 16 is longer than the left puncture push rod 15. The left puncture top screw 17 and the left puncture suture 12 are both located in the left puncture needle 16 and the left puncture top screw 17 and the left puncture suture 12 are not connected. The left puncture suture 12 is connected to the left puncture fixture 13. The left puncture fixture 13 is located in the left puncture needle 16 and is arranged along the length direction of the left puncture needle 16.

[0047] Further, refer to Figure 3 and Figure 4The firing assembly 11 includes a fixing frame 111, a baffle 112 and a firing handle 113. The fixing frame 111 is slidably arranged in the shell 14, the baffle 112 is connected to the fixing frame 111, and the end of the left puncture top screw 17 away from the left puncture fixture 13 is connected to the baffle 112. The firing handle 113 is rotatably connected to the shell 14, and the firing handle 113 drives the fixing frame 111 to slide.

[0048] The specific firing process is as follows: first, the left puncture needle 16 is inserted into the fiber ring incision, and the firing handle 113 is pulled. The firing handle 113 moves the fixing frame 111, that is, the fixing frame 111 moves toward one end close to the left puncture fixture 13. The movement of the fixing frame 111 drives the baffle 112 to move, and further drives the left puncture top screw 17 to move toward the direction close to the left puncture fixture 13. First, the left puncture top screw 17 abuts against the left puncture fixture 13, and as the left puncture top screw 17 continues to move, the left puncture fixture 13 is ejected from the left puncture needle 16. After confirming that the left puncture fixture 13 has completely entered the incision, the left puncture needle 16 can be pulled out.

[0049] Reference Figure 3 and Figure 4 The firing assembly 11 further includes a tension spring 114, one end of which is connected to the housing 14, and the other end of which is connected to the fixing frame 111. In this way, after the firing handle 113 is pulled, the tension spring 114 is in a tensioned state, which can ensure that the left puncture fixture 13 completely enters the incision; when the firing handle 113 is no longer pulled, under the action of the tension spring 114, the firing handle 113 and the fixing frame 111 are automatically reset.

[0050] It should be noted that, as required, the length of the left puncture needle 16 extending out of the housing 14 can be adjusted. In this embodiment, the length of the left puncture needle 16 extending out of the housing 14 can be 300 mm ± 5 mm, 175 mm ± 5 mm, or 145 mm ± 5 mm to meet the needs of different surgeries. In this embodiment, the initial distance between the fixing frame 111 and the left puncture needle 16 is 29.5 mm-30.5 mm, and the total stroke of the fixing frame 111 is 7 mm-8 mm. In this way, the stroke can be minimized while ensuring that the left puncture fixture 13 can be delivered into the incision, thereby ensuring stability during the operation.

[0051] Reference Figure 3 and Figure 4In order to facilitate the installation of left puncture needles 16 of different lengths, and because the left puncture needle 16 and the left puncture push rod 15 are relatively long, in order to improve the stability during use, the firing assembly 11 further includes a connecting block 115, which is disposed on the housing 14, and the left puncture needle 16 and the left puncture push rod 15 are connected to the connecting block 115, and the connecting block 115 is provided with a through hole for the left puncture top screw 17 to pass through. The connecting block 115 plays the role of a connecting hub to ensure the stability of the connecting structure.

[0052] Reference Figure 5 , Figure 6 and Figure 7 The pushing assembly 21 includes a first injection molded handle 211, a second injection molded handle 212, a right puncture push rod 213, a right puncture needle 214 and a right puncture top screw 215. The first injection molded handle 211 is hollow in design. The right puncture push rod 213 is connected to the first injection molded handle 211. The right puncture needle 214 is inserted into the right puncture push rod 213 and the right puncture needle 214 is longer than the right puncture push rod 213. The right puncture suture 22 and the right puncture fixture 23 are both located in the right puncture needle 214. The right puncture top screw 215 is connected to the second injection molded handle 212. The second injection molded handle 212 can slide in the first injection molded handle 211, and the right puncture top screw 215 can slide in the right puncture needle 214.

[0053] The specific right puncture process is as follows: first, the right puncture needle 214 is inserted into the incision, and then the right puncture top screw 215 is inserted into the right puncture needle 214 through the first injection handle 211, and at the same time, the second injection handle 212 is inserted into the first injection handle 211, and the second injection handle 212 is pushed to slide in the first injection handle 211, thereby driving the right puncture top screw 215 to move, so as to push the right puncture fixture 23 out of the right puncture needle 214. The right puncture mechanism 2 has a simpler structure and is easier to operate.

[0054] It should be noted that the right puncture mechanism 2 can also adopt a gun-type structure, but when both the right puncture mechanism 2 and the left puncture mechanism 1 adopt a gun-type structure, the packaging difficulty and cost will be increased. Therefore, in combination with the actual situation, the right puncture mechanism 2 adopts a simpler injection handle structure to cooperate with the left puncture mechanism 1 to complete the fiber ring suture operation. In this way, the volume of the entire device can be reduced, and then the size of the package can be reduced, thereby reducing the cost and the size of the occupied space.

[0055] In this embodiment, two right puncture mechanisms 2 are provided, and one of the right puncture mechanisms 2 can be used as a backup. When the used left puncture mechanism 1 or the right puncture mechanism 2 fails, the backup right puncture mechanism 2 can be used as a replacement to ensure the normal progress of the operation.

[0056] Of course, there is a gap between the right puncture fixture 23 and the right puncture needle 214, and the right puncture top screw 215 cannot pass through, and there is a gap between the left puncture fixture 13 and the left puncture needle 16, and the left puncture top screw 17 cannot pass through. In this way, the left puncture top screw 17 or the right puncture top screw 215 can be prevented from passing through the gap while ensuring that the left puncture fixture 13 or the right puncture fixture 23 is easily pushed out.

[0057] In this embodiment, the front end of the right puncture needle 214 extends 18mm-20mm beyond the front end of the right puncture push rod 213, and the front end of the left puncture needle 16 extends 18mm-20mm beyond the front end of the left puncture push rod 15. In this way, it can be ensured that the insertion depth of the left puncture needle 16 or the right puncture needle 214 meets the requirements, and it can meet the different needs of different patients, and has strong adaptability.

[0058] Reference Figure 1 Furthermore, the housing 14 includes a left housing 141 and a right housing 142, and the left housing 141 and the right housing 142 are detachably connected. Not only does it not require secondary assembly of the product before use, but it is also convenient for human body to hold, which saves time and effort in operation, reduces the risk of product failure rate, and improves surgical efficiency. At the same time, the detachable connection between the left housing 141 and the right housing 142 can reduce the difficulty of installing various parts in the housing 14, and can also fix various parts.

[0059] Reference Figure 3 The firing handle 113 is formed with a hand-held portion 3, and the hand-held portion 3 is wavy. The wavy hand-held portion 3 is convenient for the staff to hold, which can reduce the difficulty of operation.

[0060] In this embodiment, the end of the left puncture needle 16 away from the connecting block 115 and the end of the right puncture needle 214 away from the second injection handle 212 are both formed with oblique cuts to facilitate the insertion of the left puncture needle 16 or the right puncture needle 214 into the fiber ring incision.

[0061] The implementation principle of the disposable fiber ring suture device of the embodiment of the present application is as follows: the left puncture mechanism 1 and the right puncture mechanism 2 are used in combination. When performing fiber ring suture, the left puncture needle 16 is inserted from the left side of the fiber ring incision, the firing handle 113 is triggered, and the firing handle 113 drives the fixing frame 111 to slide, prompting the left puncture top screw 17 to move toward one end close to the left puncture fixture 13 until the left puncture fixture 13 is pushed out from the left puncture needle 16. After confirming that the left puncture fixture 13 has completely entered the incision, the firing handle 113 is released and the left puncture needle 16 is pulled out. Then, the right puncture needle 214 is inserted into the incision, and then the right puncture top screw 215 is inserted into the right puncture needle 214 through the first injection handle 211, and the second injection handle 212 is pushed to drive the right puncture top screw 215 to move, so as to push the right puncture fixture 23 out of the right puncture needle 214. After confirming that the right puncture fixture 23 has completely entered the incision, the right puncture needle 214 is pulled out. The right puncture suture 22 and the left puncture suture 12 are knotted and the excess part is cut off to complete the suturing of the fiber ring. In this way, the left puncture top screw 17 can be used to deliver the left puncture fixture 13 into the incision, and the right puncture fixture 23 can also be quickly entered into the incision through the first injection handle 211 and the second injection handle 212. The structure of the device is simple, which correspondingly simplifies the suturing process, is easy to operate, and does not require manual assembly before surgery, thereby improving the efficiency of the operation.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
