Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinal endoscopy technology, and in particular to a device for releasing elastic nerve root adhesions under spinal endoscopy. Background Technology
[0002] Endoscopic techniques for spinal interbody fusion are commonly used to treat lumbar disc herniation. The intervertebral foramen approach is the most widely applicable. This endoscope can help to accurately place and adjust the fusion device to a height suitable for the patient. However, in existing spinal interbody fusion endoscopes, the mounting base and the implantation sleeve are fixed. After the implantation sleeve is inserted into the human body, the nerve adheres to the implantation sleeve under the action of elasticity and becomes stuck, which affects the working effect.
[0003] To address the aforementioned technical issues, a patent document with publication number (CN219814241U) discloses a device for releasing adhesions of elastic nerve roots under spinal endoscopy. This device includes components such as an implantable sleeve, an endoscope outer tube, a mounting base, and a flat-mouth base. A base is inserted into the rear end of the endoscope outer tube, and a reflector and camera module are mounted on the base. The implantable sleeve can rotate relative to the base. The flat-mouth base has a third internal threaded hole and is integrally formed on the mounting base. By incorporating a bearing within the implantable sleeve, a rotatable connection is achieved between the implantable sleeve and the endoscope outer tube, enabling the sleeve to rotate. Therefore, when an elastic nerve adheres to the implantable sleeve, rotating the sleeve allows for separation from the elastic nerve, facilitating medical procedures.
[0004] However, the aforementioned existing technologies do not allow for easy control of the insertion depth of the endoscope's outer tube. During treatment, the outer tube is prone to shaking and displacement, which can affect the doctor's operation. Utility Model Content
[0005] The purpose of this invention is to provide a device for releasing elastic nerve root adhesions under spinal endoscopy, which aims to solve the technical problem in the prior art that it is not easy to control the insertion depth of the endoscope tube, and the endoscope tube is prone to shaking and displacement during treatment, thus affecting the doctor's operation.
[0006] To achieve the above objectives, this utility model employs a spinal endoscopic elastic nerve root adhesion release device, comprising an implantation sleeve and a release mechanism. The release mechanism includes an endoscope body, an endoscope outer tube, a bearing, a fixing plate, a rotating ring, two limiting rings, a first fastener, a fixing component, and a gripping component. The fixing plate is disposed inside the implantation sleeve and is rotatably connected to the implantation sleeve via the bearing. The rotating ring is sleeved on the outside of the implantation sleeve and is rotatably connected to it. Both limiting rings are sleeved on the outside of the implantation sleeve and respectively fit against the rotating ring. The fixing component is fixedly connected to the rotating ring. The first fastener is threadedly connected to the rotating ring. One end of the endoscope outer tube is fixedly connected to the endoscope body, and the other end of the endoscope outer tube is inserted into the inside of the implantation sleeve and passes through the fixing plate. The gripping component is disposed on the outside of the implantation sleeve.
[0007] The first fastener includes a first threaded rod and a first knob. One end of the first threaded rod is fixedly connected to the first knob, and the other end of the first threaded rod passes through the rotating ring and is threadedly connected to the rotating ring.
[0008] The fixing component includes a sleeve frame, two connecting brackets, and a second fastener. The sleeve frame is fitted onto the outside of the endoscope tube. One end of each of the two connecting brackets is fixedly connected to the sleeve frame, and the other end of each of the two connecting brackets is fixedly connected to the rotating ring. The second fastener is threadedly connected to the sleeve frame.
[0009] The second fastener includes a second threaded rod and a second knob. One end of the second threaded rod is fixedly connected to the second knob, and the other end of the second threaded rod passes through the sleeve frame and is threadedly engaged with the sleeve frame.
[0010] The grip assembly includes a grip bar, a baffle, and an anti-slip sleeve. One end of the grip bar is fixedly connected to the implanted sleeve, and the other end of the grip bar is fixedly connected to the baffle. The anti-slip sleeve is fitted over the outside of the grip bar.
[0011] This invention discloses a device for releasing elastic nerve root adhesions under spinal endoscopy. The fixing plate is rotatably connected to the implantation sleeve via a bearing. A rotating ring is fitted onto the outside of the implantation sleeve. The fixing assembly is fixedly connected to the rotating ring. In actual use, the rotating ring is fixed to the implantation sleeve using a first fastener. Then, the endoscope tube is inserted into the implantation sleeve, penetrating the fixing plate. After insertion to a specified depth, the endoscope tube is fixed to the rotating ring using the fixing assembly, thereby fixing the insertion depth of the endoscope tube. When the elastic nerve root adheres to the implantation sleeve, the first fastener is loosened, allowing the implantation sleeve and the rotating ring to rotate relative to each other. Then, the gripping assembly is rotated, causing the implantation sleeve to rotate, thereby separating the elastic nerve from the implantation sleeve. This method effectively solves the problem in existing technologies where it is difficult to control the insertion depth of the endoscope tube, and during treatment, the endoscope tube is prone to shaking and displacement, affecting the doctor's operation.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a device for releasing elastic nerve root adhesions under spinal endoscopy, including an implantation sleeve 101 and a release mechanism. The release mechanism includes an endoscope body 102, an endoscope outer tube 103, a bearing 104, a fixing plate 105, a rotating ring 106, two limiting rings 107, a first fastener, a fixing component, and a gripping component. The first fastener includes a first threaded rod 108 and a first knob 109. The fixing component includes a sleeve frame 110, two connecting brackets 111, and a second fastener. The second fastener includes a second threaded rod 112 and a second knob 113. The gripping component includes a grip bar 114, a baffle 115, and an anti-slip sleeve 116. The aforementioned solution solves the problem in the prior art that it is inconvenient to control the insertion depth of the endoscope outer tube, and that during treatment, the endoscope outer tube is prone to shaking and displacement, thus affecting the doctor's operation.
[0021] In this specific embodiment, the fixing plate 105 is disposed inside the implantation sleeve 101. The fixing plate 105 is rotatably connected to the implantation sleeve 101 via the bearing 104. The rotating ring 106 is sleeved on the outside of the implantation sleeve 101 and rotatably connected to it. Both limiting rings 107 are sleeved on the outside of the implantation sleeve 101 and respectively fit against the rotating ring 106. The fixing assembly is fixedly connected to the rotating ring 106. The first fastener is threadedly connected to the rotating ring 106. One end of the endoscope outer tube 103 is fixedly connected to the endoscope body 102, and the other end of the endoscope outer tube 103 is inserted into the inside of the implantation sleeve 101 and passes through the fixing plate 105. The gripping assembly is disposed on... In practical use, the outer side of the implantation sleeve 101 is secured to the rotating ring 106 by the first fastener. Then, the endoscope outer tube 103 is inserted into the interior of the implantation sleeve 101 and passes through the fixing plate 105. After insertion to a specified depth, the endoscope outer tube 103 is fixed to the rotating ring 106 by the fixing component, thereby fixing the insertion depth of the endoscope outer tube 103. When the elastic nerve root adheres to the implantation sleeve 101, the first fastener is loosened, allowing the implantation sleeve 101 and the rotating ring 106 to rotate relative to each other. Then, the gripping component is rotated, causing the implantation sleeve 101 to rotate, thereby separating the elastic nerve from the implantation sleeve 101.
[0022] One end of the first threaded rod 108 is fixedly connected to the first knob 109, and the other end of the first threaded rod 108 passes through the rotating ring 106 and is threadedly connected to the rotating ring 106. In actual use, rotating the first knob 109 causes the first threaded rod 108 to rotate, so that the first threaded rod 108 abuts against the outer wall of the implantation sleeve 101, thereby fixing the rotating ring 106 to the implantation sleeve 101.
[0023] Secondly, the sleeve 110 is fitted onto the outside of the endoscope outer tube 103. One end of each of the two connecting brackets 111 is fixedly connected to the sleeve 110, and the other end of each of the two connecting brackets 111 is fixedly connected to the rotating ring 106. The second fastener is threadedly connected to the sleeve 110. In actual use, the endoscope outer tube 103 is inserted through the sleeve 110. After the endoscope outer tube 103 is inserted to a specified depth, the endoscope outer tube 103 is fixed to the sleeve 110 by the second fastener.
[0024] Meanwhile, one end of the second threaded rod 112 is fixedly connected to the second knob 113, and the other end of the second threaded rod 112 passes through the sleeve 110 and is threadedly engaged with the sleeve 110. In actual use, rotating the second knob 113 causes the second threaded rod 112 to rotate, so that the second threaded rod 112 abuts against the endoscope outer tube 103, thereby fixing the endoscope outer tube 103 to the sleeve 110.
[0025] In addition, one end of the grip 114 is fixedly connected to the implantation sleeve 101, and the other end of the grip 114 is fixedly connected to the baffle 115. The anti-slip sleeve 116 is sleeved on the outside of the grip 114. In actual use, rotating the grip 114 will cause the implantation sleeve 101 to rotate. The baffle 115 improves the grip feel, and the anti-slip sleeve 116 can enhance the friction of the grip 114.
[0026] In the specific use of the spinal endoscopy elastic nerve root adhesion release device of this embodiment, the first knob 109 is rotated, which drives the first threaded rod 108 to rotate, so that the first threaded rod 108 abuts against the outer wall of the implantation sleeve 101, thereby fixing the rotating ring 106 to the implantation sleeve 101. Then, the endoscope outer tube 103 passes through the sleeve frame 110 and is inserted into the interior of the implantation sleeve 101, and passes through the fixing plate 105. When it is inserted to a specified depth, the second knob 113 is rotated, which drives the second threaded rod 112 to rotate, so that the second threaded rod 112 abuts against the endoscope. The outer tube 103 abuts against the endoscope, thereby fixing the endoscope outer tube 103 to the sleeve 110, thus fixing the insertion depth of the endoscope outer tube 103. When the elastic nerve root adheres to the implantation sleeve 101, the first threaded rod 108 is loosened, allowing the implantation sleeve 101 and the rotating ring 106 to rotate relative to each other. Then, the grip rod 114 is rotated, and the grip rod 114 drives the implantation sleeve 101 to rotate, thereby separating the elastic nerve from the implantation sleeve 101. This method can effectively solve the problem in the prior art that it is not convenient to control the insertion depth of the endoscope outer tube, and that the endoscope outer tube is prone to shaking and displacement during treatment, thus affecting the doctor's operation.
[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
