Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a spinal endoscopy dura mater closure device. Background Technology

[0002] A dural tear refers to a pathological condition in which the tough connective tissue membrane surrounding the spinal cord and cauda equina develops a tear, hole, or rupture. It is often caused by spinal surgery, spinal trauma, or iatrogenic injury. The subarachnoid space inside the dura mater is filled with cerebrospinal fluid (CSF). A tear in this space can lead to CSF ​​leakage. Mild leakage can cause postoperative headaches, dizziness, and local subcutaneous effusion; severe leakage can cause spinal canal infection, nerve compression, and even affect the recovery of neurological function. Clinical diagnosis mainly relies on intraoperative direct visualization, postoperative imaging examinations, and symptom assessment. Treatment depends on the size and location of the tear: small tears can be repaired with sutures or adhesive tape; complex or larger tears require a dural tear occluder to physically block leakage and guide tissue healing. Timely repair of the tear and control of CSF leakage are crucial to avoiding complications and ensuring neurological function.

[0003] In the preparation process for sealing ruptures using a dura mater occluder, the occluder needs to be inserted into the catheter during installation. However, due to the small size of the occluder, the installation process of the existing occluder is quite troublesome. In addition, during subsequent use, the insertion and connection of the occluder membrane in the existing occluder requires multiple steps. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a spinal endoscopy dura mater occlusion device.

[0005] The technical solution adopted to solve the above technical problems is: to provide a spinal endoscopic dura mater occlusion device, including a catheter mechanism, wherein an auxiliary thin tube mechanism is provided inside the catheter mechanism, and a guide wire mechanism is slidably connected to the inner wall of the auxiliary thin tube mechanism; An outer membrane sealing mechanism is provided between one end of the outer wall of the guidewire mechanism and the inner wall of the catheter mechanism, and an inner membrane sealing mechanism is provided between one end of the guidewire mechanism and the inner wall of the catheter mechanism.

[0006] Furthermore, the catheter mechanism includes an insertion catheter, one end of which is fixedly connected to a handheld plastic sleeve, and the outer wall of the handheld plastic sleeve is fixedly connected to a rubber sleeve.

[0007] With the above technical solution, when inserting the occluder, one end of the insertion catheter is inserted into the rupture of the dura mater, thereby enabling the insertion of the external membrane occlusion mechanism and the internal membrane occlusion mechanism.

[0008] Furthermore, the auxiliary capillary mechanism includes a positioning sleeve slidably connected to one end of the inner wall of the catheter mechanism. A first push rod is fixedly connected to one end of the outer wall of the positioning sleeve. A first fixed shaft is provided at one end of the first push rod. A first extension rod is rotatably connected to the first fixed shaft. A guide sleeve is fixedly connected to the center of the first push rod on the side away from the positioning sleeve. An auxiliary insertion capillary is fixedly connected to the inner wall of the positioning sleeve.

[0009] With the above technical solution, when the outer membrane occlusion mechanism is launched in the future, the first push rod is pushed, and then the positioning sleeve and the auxiliary insertion tube are used to drive the outer membrane occlusion mechanism, so that it can move on the guide wire mechanism. At the same time, the rotation of the first extension rod can be used to fix the entire auxiliary tube mechanism at any time by pressing with the palm of the hand, so as to avoid displacement.

[0010] Furthermore, the auxiliary insertion tube has a multi-groove structure at the end furthest from the positioning sleeve.

[0011] Through the above technical solution, after the occluder is installed, the multi-groove structure at one end of the thin tube is used to engage multiple inclined limiting blocks, thereby limiting the inner membrane occlusion mechanism and preventing it from rotating arbitrarily.

[0012] Furthermore, the guide wire mechanism includes a central guide wire slidably connected to the inner wall of the auxiliary thin tube mechanism. One end of the central guide wire is fixedly connected to an integral threaded rod, and the other end of the central guide wire is fixedly connected to a second push rod. A second fixed shaft is provided at the bottom of the second push rod, and a second extension rod is rotatably connected to the second fixed shaft.

[0013] With the above technical solution, during installation, pushing the second push rod will in turn push the first push rod, causing the overall auxiliary capillary mechanism and guide wire mechanism to extend simultaneously. This allows one end of the auxiliary insertion capillary and the central guide wire to protrude from the other end of the insertion catheter. Then, the outer membrane occlusion mechanism is fitted onto the protruding auxiliary insertion capillary, and the inner membrane occlusion mechanism is then spirally connected to the integrated threaded rod. The integrated threaded rod connects the guide wire mechanism and the inner membrane occlusion mechanism. Finally, pulling the second push rod will, through the central guide wire, actuate the outer membrane occlusion mechanism and the inner membrane occlusion mechanism. The membrane occlusion mechanism is inserted into the catheter. During insertion, one end of the catheter is inserted into the rupture of the dura mater, and then the second push rod is pushed. This pushes the central guidewire to extend the inner membrane occlusion mechanism into the dura mater rupture. Then, the second extension rod is rotated to fit against the outer wall of the rubber sleeve. The entire guidewire mechanism is fixed by pressing the second extension rod with the palm. During subsequent disassembly, the second push rod is rotated, which causes the central guidewire and the integrated threaded rod to reverse, disengaging them from the inner membrane occlusion mechanism.

[0014] Furthermore, the outer membrane sealing mechanism includes a first alloy ring, with multiple first elastic alloy wires fixedly connected between the two sides of the first alloy ring, and an external sealing membrane disposed between the outer wall of the first alloy ring and the multiple first elastic alloy wires.

[0015] The above technical solution drives the first push rod, which in turn drives the external membrane occlusion mechanism through the positioning sleeve and the auxiliary insertion tube, enabling it to move on the guide wire mechanism, extend from inside the catheter mechanism, and connect with the internal membrane occlusion mechanism.

[0016] Furthermore, the inner membrane sealing mechanism includes a sealing connecting rod. A second alloy ring is fixedly connected to one end of the outer wall of the sealing connecting rod. Multiple second elastic alloy wires are fixedly connected between the two sides of the second alloy ring. An internal sealing membrane is provided between the outer wall of the second alloy ring and the multiple second elastic alloy wires. Multiple third fixed shafts are provided at the other end of the sealing connecting rod. An inclined limiting block is rotatably connected to each of the multiple third fixed shafts. A reset metal spring is fixedly connected to one side of each of the multiple inclined limiting blocks and the sealing connecting rod. A threaded hole is opened at the center of the end of the sealing connecting rod near the third fixed shaft.

[0017] Through the above technical solution, during installation, the guide wire mechanism and the inner membrane occlusion mechanism are connected via an integrated threaded rod and threaded hole. Then, pulling the second push rod drives the outer and inner membrane occlusion mechanisms into the insertion catheter, causing deformation of the multiple first elastic alloy wires, the external occlusion membrane, the multiple second elastic alloy wires, and the internal occlusion membrane within the outer and inner membrane occlusion mechanisms. During insertion, the second push rod is pushed, which in turn pushes the inner membrane occlusion mechanism through the central guide wire to extend within the dura mater rupture. During extension, the multiple second elastic alloy wires disengage from the insertion catheter's limiting position. Then it begins to unfold, so that the entire built-in sealing membrane is fully unfolded into a flat structure and fits the inner wall of the rigid ridge membrane. When the outer membrane sealing mechanism is installed later, the first push rod is pushed, and then the first alloy ring in the outer membrane sealing mechanism is pushed through the positioning sleeve and the auxiliary insertion thin tube until the first alloy ring begins to squeeze multiple inclined limit blocks and at the same time begins to compress multiple corresponding reset metal springs until the second alloy ring passes over multiple inclined limit blocks. At this time, under the action of multiple compressed reset metal springs, multiple inclined limit blocks are reset, and the limiting and fixing of the outer membrane sealing mechanism is completed.

[0018] Furthermore, the sealing connecting rod has multiple grooves on the side near the third fixed shaft that correspond to the inclined limiting block and the reset metal spring.

[0019] The above technical solution ensures that a certain space is provided for the rotating inclined limit block and the reset metal spring to achieve the compression function. When the second alloy ring passes over multiple inclined limit blocks, the multiple inclined limit blocks are reset under the action of multiple compressed reset metal springs to complete the limiting.

[0020] The beneficial effects of the present invention are as follows: (1) By designing an auxiliary capillary mechanism, a guidewire mechanism, an outer membrane occlusion mechanism, and an inner membrane occlusion mechanism, the present invention allows the installation of the overall occluder to be completed in only three steps during the installation process. The outer membrane occlusion mechanism is fitted onto the guidewire mechanism, and then the inner membrane occlusion mechanism and the guidewire mechanism are spirally connected. Finally, the overall guidewire mechanism is pulled to move the outer membrane occlusion mechanism and the inner membrane occlusion mechanism into the inside of the catheter mechanism. The installation is simple. At the same time, when inserting the occluder later, the inner membrane occlusion mechanism can be inserted simply by pushing the guidewire mechanism. (1) Keep the guide wire mechanism stationary and push the auxiliary thin tube mechanism to complete the insertion of the outer membrane sealing mechanism. The operation is relatively easy. (2) By designing the inner membrane sealing mechanism, the present invention designs the auxiliary insertion thin tube, the inclined limit block, the reset metal spring and the threaded hole. After the outer membrane sealing mechanism is installed, it can be limited by the inclined limit block. Then, with the groove structure at one end of the auxiliary insertion thin tube, the overall inner membrane sealing mechanism can be limited. While ensuring that the overall auxiliary thin tube mechanism is stationary, the guide wire mechanism can be rotated, thereby realizing the connection and disassembly of the guide wire mechanism and the inner membrane sealing mechanism. The disassembly is quick. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] like Figures 1-4 As shown, an endoscopic spinal dura mater occlusion device of this embodiment includes a catheter mechanism 1. The catheter mechanism 1 includes an insertion catheter 101. One end of the outer wall of the insertion catheter 101 is fixedly connected to a handheld plastic sleeve 102. The outer wall of the handheld plastic sleeve 102 is fixedly connected to a rubber sleeve 103. When inserting the occlusion device, by inserting one end of the insertion catheter 101 into the dura mater tear, the external membrane occlusion mechanism 4 and the internal membrane occlusion mechanism 5 can be inserted through the insertion catheter 101.

[0025] like Figures 1-8As shown, the catheter mechanism 1 is internally equipped with an auxiliary capillary mechanism 2. The auxiliary capillary mechanism 2 includes a positioning sleeve 201 slidably connected to one end of the inner wall of the catheter mechanism 1. A first push rod 202 is fixedly connected to one end of the outer wall of the positioning sleeve 201. A first fixed shaft 203 is provided at one end of the first push rod 202. A first extension rod 204 is rotatably connected to the first fixed shaft 203. A guide sleeve 205 is fixedly connected to the center of the first push rod 202 on the side away from the positioning sleeve 201. An auxiliary insertion capillary 206 is fixedly connected to the inner wall of the positioning sleeve 201. When the outer membrane sealing mechanism 4 is subsequently pushed out, the first push rod 206 is pushed. The rod 202, through the positioning sleeve 201 and the auxiliary insertion tube 206, drives the external membrane occlusion mechanism 4, enabling it to move on the guide wire mechanism 3. At the same time, the rotation of the first extension rod 204 can be fixed at any time by pressing with the palm of the hand to prevent displacement. The auxiliary insertion tube 206 has a multi-groove structure at the end away from the positioning sleeve 201. After the occluder is installed, the multi-groove structure at one end of the auxiliary insertion tube 206 can engage multiple inclined limiting blocks 506, thereby limiting the internal membrane occlusion mechanism 5 and preventing it from rotating arbitrarily.

[0026] like Figures 1-8As shown, a guide wire mechanism 3 is slidably connected to the inner wall of the auxiliary capillary mechanism 2. The guide wire mechanism 3 includes a central guide wire 301 slidably connected to the inner wall of the auxiliary capillary mechanism 2. One end of the central guide wire 301 is fixedly connected to an integral threaded rod 302, and the other end of the central guide wire 301 is fixedly connected to a second push rod 303. A second fixed shaft 304 is provided at the bottom of the second push rod 303, and a second extension rod 305 is rotatably connected to the second fixed shaft 304. During installation, pushing the second push rod 303 will push the first push rod 202, causing the entire auxiliary capillary mechanism 2 and guide wire mechanism 3 to be pushed out simultaneously. This allows one end of the auxiliary insertion capillary 206 and the central guide wire 301 to extend from the other end of the insertion catheter 101. Then, the outer membrane sealing mechanism 4 is sleeved on the extended auxiliary insertion capillary 206, and then the inner membrane sealing mechanism 5 is spirally connected to the inner membrane sealing mechanism 3. On the integrated threaded rod 302, the guide wire mechanism 3 and the inner membrane occlusion mechanism 5 are connected. Then, the second push rod 303 is pulled, which in turn drives the outer membrane occlusion mechanism 4 and the inner membrane occlusion mechanism 5 into the insertion catheter 101 through the central guide wire 301. When inserting the occluder, one end of the insertion catheter 101 is inserted into the rupture of the dura mater. Then, the second push rod 303 is pushed, which in turn pushes the inner membrane occlusion mechanism 5 to extend out of the dura mater rupture through the central guide wire 301. Then, the second extension rod 305 is rotated to fit against the outer wall of the rubber sleeve 103. The entire guide wire mechanism 3 is fixed by pressing the second extension rod 305 with the palm. During subsequent disassembly, the second push rod 303 is rotated, which in turn drives the central guide wire 301 and the integrated threaded rod 302 to reverse, so that they are disconnected from the inner membrane occlusion mechanism 5.

[0027] like Figures 1-11 As shown, an outer membrane sealing mechanism 4 is provided between one end of the outer wall of the guidewire mechanism 3 and the inner wall of the catheter mechanism 1. The outer membrane sealing mechanism 4 includes a first alloy ring 401, and multiple first elastic alloy wires 402 are fixedly connected between the two sides of the first alloy ring 401. An external sealing membrane 403 is provided between the outer wall of the first alloy ring 401 and the multiple first elastic alloy wires 402. Pushing the first push rod 202, and then through the positioning sleeve 201 and the auxiliary insertion thin tube 206, the outer membrane sealing mechanism 4 is driven, so that it can move on the guidewire mechanism 3, extend out of the catheter mechanism 1, and connect with the inner membrane sealing mechanism 5.

[0028] like Figures 1-14As shown, an inner membrane sealing mechanism 5 is provided between one end of the guidewire mechanism 3 and the inner wall of the catheter mechanism 1. The inner membrane sealing mechanism 5 includes a sealing connecting rod 501. A second alloy ring 502 is fixedly connected to one end of the outer wall of the sealing connecting rod 501. Multiple second elastic alloy wires 503 are fixedly connected between the two sides of the second alloy ring 502. An internal sealing membrane 504 is provided between the outer wall of the second alloy ring 502 and the multiple second elastic alloy wires 503. Multiple third fixed shafts 505 are provided at the other end of the sealing connecting rod 501. An inclined limiting block 506 is rotatably connected to each of the multiple third fixed shafts 505. One side of the multiple inclined limiting blocks 506 is connected to the sealing connecting rod 501. Each part is fixedly connected with a reset metal spring 507. The sealing connecting rod 501 has a threaded hole 508 at the center of one end near the third fixed shaft rod 505. During installation, the guide wire mechanism 3 and the inner membrane sealing mechanism 5 are connected through the integrated threaded rod 302 and the threaded hole 508. Then, the second push rod 303 is pulled to drive the outer membrane sealing mechanism 4 and the inner membrane sealing mechanism 5 into the insertion catheter 101. This causes the multiple first elastic alloy wires 402, the external sealing membrane 403, the multiple second elastic alloy wires 503, and the internal sealing membrane 504 in the outer membrane sealing mechanism 4 and the inner membrane sealing mechanism 5 to deform. When the occluder is inserted, the second push rod 303 is pushed, and then the central guide wire is inserted. 301 pushes the inner membrane occlusion mechanism 5 out of the dura mater tear. During this extension, multiple second elastic alloy wires 503 disengage from the insertion catheter 101, causing the membrane to unfold and fully expand into a flat structure, conforming to the inner wall of the dura mater. During the subsequent installation of the outer membrane occlusion mechanism 4, the first push rod 202 is pushed, which in turn pushes the first alloy ring 401 in the outer membrane occlusion mechanism 4 through the positioning sleeve 201 and the auxiliary insertion tube 206, until the first alloy ring 401 begins to compress along the inclined surfaces of multiple inclined limiting blocks 506, simultaneously compressing multiple corresponding reset metal springs 507, until the second alloy ring 502 passes over... Multiple inclined limit blocks 506 are reset under the action of multiple compressed reset metal springs 507, thus completing the limiting and fixing of the outer membrane sealing mechanism 4. The sealing connecting rod 501 has multiple grooves on the side near the third fixed shaft rod 505 that correspond to the inclined limit blocks 506 and the reset metal springs 507, ensuring that a certain space is provided for the rotating inclined limit blocks 506 and the reset metal springs 507 to achieve the compression function. When the second alloy ring 502 passes over the multiple inclined limit blocks 506, the multiple inclined limit blocks 506 are reset under the action of multiple compressed reset metal springs 507, thus completing the limiting.

[0029] The working principle of this embodiment is as follows: During the operation, the occluder packaging is opened and the outer membrane occlusion mechanism 4 and the inner membrane occlusion mechanism 5 are taken out. The sterilized catheter mechanism 1, auxiliary capillary mechanism 2, and guidewire mechanism 3 are picked up. During installation, the second push rod 303 is pushed, which in turn pushes the first push rod 202, causing the entire auxiliary capillary mechanism 2 and guidewire mechanism 3 to be pushed out simultaneously. This allows one end of the auxiliary insertion capillary 206 and the central guidewire 301 to extend from the other end of the insertion catheter 101. Then, the first alloy ring 401 in the outer membrane occlusion mechanism 4 is fitted onto the extended auxiliary insertion capillary 206. Then, the sealing connecting rod 501 in the inner membrane sealing mechanism 5 is screwed onto the integrated threaded rod 302. The connection between the guide wire mechanism 3 and the inner membrane sealing mechanism 5 is achieved through the integrated threaded rod 302 and the threaded hole 508. Then, the second push rod 303 is pulled, which in turn drives the outer membrane sealing mechanism 4 and the inner membrane sealing mechanism 5 into the interior of the insertion catheter 101 through the central guide wire 301. This causes the multiple first elastic alloy wires 402, the external sealing membrane 403, the multiple second elastic alloy wires 503, and the internal sealing membrane 504 in the outer membrane sealing mechanism 4 and the inner membrane sealing mechanism 5 to deform. During insertion of the occluder, one end of the insertion catheter 101 is inserted into the rupture of the dura mater. Then, the second push rod 303 is pushed, which in turn pushes the inner membrane occlusion mechanism 5 through the central guide wire 301 to extend within the dura mater rupture. During extension, multiple second elastic alloy wires 503 disengage from the limiting position of the insertion catheter 101, causing it to unfold and fully expand the entire internal occlusion membrane 504 into a flat structure, conforming to the inner wall of the dura mater. Then, the second extension rod 305 is rotated to conform to the outer wall of the rubber sleeve 103, and the entire guide wire mechanism 3 is fixed by pressing the second extension rod 305 with the palm. At this point, the first push rod 202 is pushed, which in turn pushes the positioning sleeve 201 and the auxiliary insertion device... The tube 206 pushes the first alloy ring 401 in the external membrane occlusion mechanism 4 until the first alloy ring 401 begins to squeeze multiple inclined limit blocks 506 and simultaneously begins to compress multiple corresponding reset metal springs 507 until the second alloy ring 502 passes over multiple inclined limit blocks 506. At this time, under the action of multiple compressed reset metal springs 507, multiple inclined limit blocks 506 are reset, thus completing the limiting and fixing of the external membrane occlusion mechanism 4. During this process, the entire external membrane occlusion mechanism 4 extends out from the insertion catheter 101. Similarly, multiple first elastic alloy wires 402 detach from the insertion catheter 101 and unfold, thereby allowing the external occlusion membrane 403 to fully unfold and adhere to the outer wall of the dura mater. The first push rod 202 is repeatedly rotated for adjustment, so that the groove at one end engages with multiple inclined limiting blocks 506. Then, the first extension rod 204 is rotated to fit against the outer wall of the rubber sleeve 103, and the auxiliary capillary mechanism 2 is fixed by pressing with the palm of the hand. At the same time, the pressure on the second extension rod 305 is released, and the second push rod 303 is rotated, which in turn drives the central guide wire 301 and the integrated threaded rod 302 to reverse, so that they are disconnected from the connection between them and the sealing connecting rod 501. Then, the overall conduit mechanism 1 is taken out, and the outer membrane sealing mechanism 4 and the inner membrane sealing mechanism 5 remain at the dura mater rupture to complete the sealing of the rupture.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
