Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a medical fiber ring suture device. Background Technology

[0002] In the field of spinal surgery, intervertebral disc degeneration and damage leading to annulus fibrosus rupture is a common problem. Traditional treatment methods often focus on nucleus pulposus removal but neglect annulus fibrosus repair. This can easily lead to postoperative complications such as loss of intervertebral disc height and narrowing of the intervertebral space, increasing patient pain and rehabilitation difficulty, and may also lead to poor long-term surgical results. With the advancement of medical technology, medical annulus fibrosus suture devices have emerged.

[0003] Most doctors currently rely on hand-held surgical needles to perform suturing operations. However, this traditional method faces many challenges. On the one hand, the hand needs to be close to the incision site, which can easily obstruct the surgical field of vision, interfere with the doctor's accurate judgment of minor wounds, and may also lead to a significant reduction in suturing precision due to unintentional hand tremors, resulting in unsatisfactory suturing results. In some complex wound situations, it may even be impossible to suture successfully. On the other hand, when operating by hand, doctors find it difficult to accurately control the specific position of the needles on both sides of the incision, and cannot flexibly adjust the relative direction of the two needles when suturing. This greatly increases the surgical risk and uncertainty, prolongs the operation time, and causes more pain to the patient. Therefore, improvements and optimizations are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a medical fiber ring suture device, which has the advantage of convenient operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical annulus fibrosus suture device, comprising a housing, a handle fixedly mounted on the outer surface of the housing, an annulus fibrosus suture assembly rotatably mounted inside the housing, the annulus fibrosus suture assembly including a trigger shaft rotatably mounted inside the housing, a trigger fixedly mounted on the outer surface of the trigger shaft and extending out of the housing, a limiting hollow sleeve fixedly mounted inside the housing, a push rod fixedly mounted at one end of the trigger and extending to the inner side of the limiting hollow sleeve, a spring seat fixedly sleeved on the outer surface of the push rod and located inside the limiting hollow sleeve, and the end of the housing fixedly mounted... A puncture needle is fixedly installed and extends into the housing. An annular seat is fixedly installed inside the limiting hollow sleeve. A push rod is fixedly connected to a pin, which extends through the annular seat to the inside of the puncture needle. A second spring is fixedly connected to the inside of the annular seat and is movably sleeved on the outer surface of the pin. A wire storage groove is formed on the outer surface of the pin. Wire ends are placed inside the wire storage groove and at the end of the pin. A fixing plate is fixedly installed on the outer surface of the housing. A limiting ring is fixedly sleeved on the outer surface of the pin. A second wire controller is slidably installed on the outer surface of the fixing plate. A second limiting plate is fixedly installed inside the second wire controller.

[0006] As a preferred embodiment of this utility model, a collar is fixedly sleeved on the outer surface of the push rod, a first wire controller is rotatably mounted on the outer surface of the housing, and a first limiting plate is fixedly mounted on the inner side of the first wire controller.

[0007] As a preferred embodiment of this utility model, a first spring frame is fixedly installed on the side of the trigger, a second spring frame is fixedly installed inside the housing, and a first spring is fixedly connected between the first spring frame and the second spring frame.

[0008] As a preferred embodiment of this invention, the front end of the thimble is curved inward and located inside the puncture needle.

[0009] As a preferred embodiment of the present invention, the outer surface of the ejector pin is provided with a graduated groove, and multiple graduated grooves are provided at uniform intervals.

[0010] As a preferred embodiment of this utility model, flexible protrusions are fixedly installed on the outer surface of the handle, and the flexible protrusions are evenly arranged in a linear array.

[0011] As a preferred embodiment of this utility model, the first spring frame and the second spring frame are C-shaped, and both ends of the first spring are fixedly connected to the inner sides of the first spring frame and the second spring frame. A travel monitoring indicator light is fixedly installed on the outer surface of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a pusher pin to push the end of the thread into the area to be sewn. Simultaneously, the thread stored in the suture trough is also pushed. At this point, the limiting ring on the outer surface of the pusher pin is locked by the second limiting plate. Then, by moving the second thread controller downwards, the second limiting plate is moved downwards, removing the obstruction to the limiting ring. This allows the trigger to be pulled to continue pinching inwards, pushing the thread end inside the suture trough into the area to be sewn. Once the insertion is complete, the pinching force of the trigger is released, and the spring force of the second spring restores the spring seat and push rod in the opposite direction. This causes the needle to be pulled out from the suture site. Compared with traditional devices, this medical device has many advantages: it is easy to operate. Medical staff only need to squeeze the trigger inward to activate the push rod, spring seat, needle and other components in sequence, accurately pushing the suture end into the suture site. The deformation of the second spring and the insertion of the puncture needle into the suture site are coordinated in a smooth manner to achieve precise suturing. The structure is simple and the components work together efficiently. For example, the trigger shaft provides rotational support for pulling the trigger, and the second limiting plate and limiting ring cleverly engage to control the process, allowing the suture end to enter at intervals. This simplifies the operation procedure for medical staff and greatly reduces their workload. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 9As shown, this utility model provides a medical annulus fibrosus suture device, including a housing 1. A handle 2 is fixedly installed on the outer surface of the housing 1. An annulus fibrosus suture assembly 3 is rotatably installed inside the housing 1. The annulus fibrosus suture assembly 3 includes a trigger shaft 301 rotatably installed inside the housing 1. A trigger 302 is fixedly installed on the outer surface of the trigger shaft 301 and extends out of the housing 1. A limiting hollow sleeve 306 is fixedly installed inside the housing 1. A push rod 307 is fixedly installed at one end of the trigger 302 and extends to the inside of the limiting hollow sleeve 306. A spring seat 308 is fixedly sleeved on the outer surface of the push rod 307 and located inside the limiting hollow sleeve 306. A puncture needle 312 is fixedly installed at the end of the housing 1 and extends outward. An annular seat 309 is fixedly installed inside the housing 1 and the inner side of the limiting hollow sleeve block 306. The end of the push rod 307 is fixedly connected to the ejector pin 311, and the ejector pin 311 extends through the annular seat 309 to the inner side of the puncture needle head 312. A second spring 310 is fixedly connected inside the annular seat 309 and is movably sleeved on the outer surface of the ejector pin 311. A wire storage groove 313 is opened on the outer surface of the ejector pin 311. A wire end 314 is placed inside the wire storage groove 313 and at the end of the ejector pin 311. A fixing plate 320 is fixedly installed on the outer surface of the housing 1. A limiting ring 319 is fixedly sleeved on the outer surface of the ejector pin 311. A second wire controller 321 is slidably installed on the outer surface of the fixing plate 320. A second limiting plate 322 is fixedly installed inside the second wire controller 321.

[0026] When medical staff squeeze the trigger 302 inward, the inward squeeze will drive the upper end of the trigger 302 to push the push rod 307 inward towards the inner side of the limiting hollow sleeve block 306. At the same time, the trigger shaft 301 provides rotational support for the trigger 302 during the push. Then, the push rod 307 will drive the spring seat 308 to compress the second spring 310 inward, and the second spring 310 will deform. At this time, the puncture needle 312 has been inserted into the area to be sutured. At the same time, the push rod 307 will push the ejector needle 311, and the ejector needle 311 will push the end of the suture 314 into the area to be sutured. At the same time, the suture end stored in the suture storage groove 313 will be stored in the suture storage groove 313. 314 will also be pushed, at which point the limiting ring 319 on the outer surface of the ejector pin 311 will be blocked by the second limiting plate 322. Then, by pushing the second wire controller 321 downward, the second limiting plate 322 will be driven downward, thus removing the obstruction to the limiting ring 319. This allows the ejector pin 311 to continue to squeeze inward by pulling the trigger 302, and then push the wire end 314 inside the wire storage groove 313 into the part that needs to be sewn. After the pushing is completed, the squeezing force of the trigger 302 will disappear. Then, through the elasticity of the second spring 310, the spring seat 308 and the push rod 307 will be pushed in the opposite direction, thereby driving the ejector pin 311 to be pulled out from the sewing site.

[0027] The ejector pin 311 pushes the end of the thread 314 into the area to be sewn, and simultaneously pushes the thread end 314 stored inside the thread storage groove 313. At this time, the limiting ring 319 on the outer surface of the ejector pin 311 will be locked by the second limiting plate 322. Then, by pushing the second thread controller 321 downward, the second limiting plate 322 is driven downward, removing the obstruction of the limiting ring 319. This allows the trigger 302 to be pulled inward, causing the ejector pin 311 to push the thread end 314 inside the thread storage groove 313 into the area to be sewn. After the insertion is complete, the pinching force of the trigger 302 is released, and then the elastic force of the second spring 310 will push the spring seat 308 and... The push rod 307 drives the ejector needle 311 to be pulled out from the suture site. Compared with traditional devices, this medical device has many advantages: it is easy to operate. Medical staff only need to squeeze the trigger 302 inward to drive the push rod 307, spring seat 308, ejector needle 311 and other components to operate in sequence, accurately pushing the suture end 314 into the suture site. The deformation of the second spring 310 and the insertion of the puncture needle 312 into the suture site are coordinated in a smooth manner to achieve precise suturing. The structure is simple and the components work together efficiently. For example, the trigger shaft 301 provides rotational support for pulling the trigger 302. The second limiting plate 322 and the limiting ring 319 cleverly engage to control the process, so that the suture end 314 can enter at intervals. This simplifies the operation procedure for medical staff and greatly reduces their workload.

[0028] Among them, a collar 317 is fixedly sleeved on the outer surface of the push rod 307, a first wire controller 316 is rotatably installed on the outer surface of the housing 1, and a first limit plate 318 is fixedly installed on the inner side of the first wire controller 316.

[0029] By turning the first wire controller 316 to the right, the first limiting plate 318 will start to rotate, thereby removing the obstruction force of the first limiting plate 318 on the collar 317. This allows the push rod 307 to be smoothly pushed into the inner side of the limiting hollow sleeve block 306, effectively preventing medical staff from accidentally squeezing and pulling the trigger 302, which would push the wire end 314 of the needle 311 out of the puncture needle 312.

[0030] The trigger 302 has a first spring frame 303 fixedly installed on its side, and a second spring frame 304 fixedly installed inside the housing 1. A first spring 305 is fixedly connected between the first spring frame 303 and the second spring frame 304.

[0031] A first spring 305 is fixedly connected between the first spring frame 303 and the second spring frame 304. When the trigger 302 is pulled, the push rod 307 is pushed forward, which will cause the first spring frame 303 to shift. Then, the first spring 305 will be pulled and deformed. When the pinching force of the trigger 302 disappears, the elasticity of the first spring 305 will cause the trigger 302 to return to its original position. This can assist the second spring 310 in pulling the pin 311 out from the place where it needs to be sewn.

[0032] The front end of the thimble 311 is curved inward and located inside the puncture needle 312.

[0033] The inward curve at the front end of the ejector pin 311 prevents the thread end 314 from being pulled out along with the ejector pin 311 when it is pulled out from the inside.

[0034] The outer surface of the ejector pin 311 is provided with a scale groove 315, and the scale groove 315 is provided with multiple grooves that are evenly spaced.

[0035] The graduated grooves 315 are evenly spaced, which allows medical staff to easily observe the position of the needle 311 and make timely adjustments.

[0036] Among them, flexible protrusions 5 are fixedly installed on the outer surface of the handle 2, and the flexible protrusions 5 are evenly arranged in a linear array.

[0037] The flexible protrusions 5 are arranged in a linear array, which can effectively increase the comfort of medical staff when using the handle 2 and relieve fatigue during long-term suturing.

[0038] The first spring frame 303 and the second spring frame 304 are C-shaped, and both ends of the first spring 305 are fixedly connected to the inner sides of the first spring frame 303 and the second spring frame 304. The travel monitoring indicator light 4 is fixedly installed on the outer surface of the housing 1.

[0039] By fixing both ends of the first spring 305 to the inner sides of the first spring bracket 303 and the second spring bracket 304, it is easy for the first spring 305 to deviate when it is stretched or extended. At the same time, the stroke monitoring indicator light 4 can monitor the stroke of the ejector pin 311.

[0040] Working principle and usage process of this utility model:

[0041] When medical staff squeeze the trigger 302 inward, the inward squeeze will drive the upper end of the trigger 302 to push the push rod 307 inward towards the inner side of the limiting hollow sleeve block 306. At the same time, the trigger shaft 301 provides rotational support for the trigger 302 during the push. Then, the push rod 307 will drive the spring seat 308 to compress the second spring 310 inward, and the second spring 310 will deform. At this time, the puncture needle 312 has been inserted into the area to be sutured. At the same time, the push rod 307 will push the ejector needle 311, and the ejector needle 311 will push the end of the suture 314 into the area to be sutured. At the same time, the suture end stored in the suture storage groove 313 will be stored in the suture storage groove 313. 314 will also be pushed, at which point the limiting ring 319 on the outer surface of the ejector pin 311 will be blocked by the second limiting plate 322. Then, by pushing the second wire controller 321 downward, the second limiting plate 322 will be driven downward, thus removing the obstruction to the limiting ring 319. This allows the ejector pin 311 to continue to squeeze inward by pulling the trigger 302, and then push the wire end 314 inside the wire storage groove 313 into the part that needs to be sewn. After the pushing is completed, the squeezing force of the trigger 302 will disappear. Then, through the elasticity of the second spring 310, the spring seat 308 and the push rod 307 will be pushed in the opposite direction, thereby driving the ejector pin 311 to be pulled out from the sewing site.
