Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a spinal endoscope access system and a connector for the spinal endoscope access system. Background Technology

[0002] Spinal surgery means avoiding large incisions while taking certain medical risks, and using small incisions or puncture channels to operate on the wound using endoscopes and fiber optic illumination tubes. This method can provide effective operating space and ensure that the surgery can be completed smoothly in a relatively narrow space.

[0003] The publication number CN212466056U discloses a spinal endoscope connection assembly, in which a first fixing plate is fixedly connected to the inner wall of a second sliding groove, a second connecting ring is movably connected to the second sliding groove through an internally set slider, and an installation box is fixedly connected to the surface of the second connecting ring. This assembly can prevent the spinal endoscope from needing to be repeatedly disassembled and adjusted to a suitable position for surgery due to an unsuitable position, thus increasing the convenience of use for medical staff.

[0004] CN219089695U discloses a spinal channel endoscope connection assembly. The connection assembly is attached to the hospital bed by a fixing bracket. Then, the connection assembly is installed on the hospital bed by driving the fixing plate through the first knob and the first screw. The spinal channel endoscope is attached to the first clamping groove on one side of the first clamping plate. The second clamping plate is fixed by driving the second knob and the second screw, which increases the use effect of the connection assembly.

[0005] However, the connecting components for the spinal endoscope channel system described above still have the following problems in actual use: The spinal endoscope is fixed by the fixation frame and the mounting box, and the mounting base is fixed on the connecting frame. The channel tube and the endoscope tube of the spinal endoscope extend into the spine. However, in actual use, the channel diameter needs to be changed according to the spine. Different incisions are made for different patients, and the range of the channel needs to be appropriately changed for the movement of the predetermined plane during the operation. This limits the operation within the overall spinal channel and affects the flexibility of the surgical operation.

[0006] Therefore, we propose a spinal endoscopy access system and a connector for the spinal endoscopy access system to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a spinal endoscope channel system and a connector for the spinal endoscope channel system, in order to solve the problems mentioned in the background art. Currently, the spinal endoscope is fixed by a fixation frame and a mounting box. The mounting box is fixed on the connector frame, and the channel tube and the endoscope tube of the spinal endoscope extend into the spine. However, in actual use, the channel diameter needs to be changed according to the spine. Different incisions are made for different patients, and the range of the channel needs to be appropriately changed for the movement of the predetermined plane during the operation. This limits the operation within the overall spinal channel and affects the flexibility of the surgical operation.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a spinal endoscope channel system, including a locking plate for the spinal endoscope channel system, wherein a secondary endoscope channel is provided at the center of the interior of the locking plate, and the lower part of the locking plate is fixedly connected to the top surface of the connecting plate.

[0009] The top surface of the locking base plate is slidably provided with guide slides on the left and right sides for positioning the endoscope or illumination tube, and the outer ends of the left and right guide slides are rotatably provided with adjustment knobs through bearings.

[0010] The auxiliary endoscope channel inside the locking plate body and the main endoscope channel inside the connecting plate body are arranged in a vertically coaxial, concentric structure, and the diameters of the auxiliary endoscope channel and the main endoscope channel are the same.

[0011] The locking seat disc has a guide groove ring inside, and a locking positioning ring is fixedly installed inside the locking seat disc. The upper and lower ends of the inner side of the locking positioning ring are slidably connected to the outer end of the positioning tooth plate. The positioning tooth plates on the upper and lower sides are connected to the locking positioning ring by a return spring.

[0012] Preferably, the positioning tooth plates on the upper and lower sides inside the locking seat disc are engaged with the inside of the guide groove ring, and the positioning tooth plates can disengage from the guide groove ring after being moved, and the top surface of the guide groove ring is fixedly connected to the bottom surface of the left and right guide slides.

[0013] Preferably, the guide slide has a guide thread rod rotatably provided inside through a bearing, and the outer ends of the guide thread rods on both the left and right sides are fixedly connected to the rotating shaft of the adjusting knob, and the inner ends of the guide thread rods on both the left and right sides are threaded to the outer ends of the guide sleeves, and the inner ends of the guide sleeves on both the left and right sides are slidably provided outside the inner end of the guide slide.

[0014] Preferably, the guide sleeve is slidably engaged with the outside of the guide slide by the outer positioning slider, and the inner ends of the left and right guide slides are fixedly connected to the inner ends of the positioning sleeve seat. The interior of the left and right positioning sleeve seats is provided with positioning guide grooves for positioning the endoscope or illumination tube, and the left and right positioning sleeve seats are both located inside the main endoscope channel.

[0015] Preferably, a main endoscope channel is provided at the center of the connecting plate body, and an expansion cavity is provided on the outer side of the connecting plate body. Moreover, a drive gear is rotatably provided on the left side of the expansion cavity inside the connecting plate body via a bearing.

[0016] Preferably, a drive gear ring is rotatably provided in the expansion cavity inside the connecting base plate body, and a guide gear is rotatably provided in the expansion cavity inside the connecting base plate body through a bearing at equal angles, and a guide rack is slidably provided in the expansion cavity at equal angles.

[0017] Preferably, the drive gear ring in the expansion cavity inside the connecting seat plate is engaged with the outer wall of the left drive gear, and the inner wall of the drive gear ring is engaged with the outer wall of the guide gear set at equal angles, and the upper outer wall of the guide gear set at equal angles is engaged with the middle part of the guide rack.

[0018] Preferably, an extension liner is slidably provided at equal angles below the connecting base plate, and the top of the extension liner is fixedly connected to the bottom of the inner end of the guide rack that is set at equal angles inside the connecting base plate. The extension liner, the guide rack, and the guide gear are distributed in a one-to-one correspondence.

[0019] Preferably, the equally angled expansion plates are all distributed in an arc shape, and the equally angled expansion plates are used to extend the spinal channel system. Furthermore, the expansion plates can achieve a self-locking effect through the guide rack driven by the drive gear ring and the guide gear, preventing the equally angled expansion plates from shifting.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The spinal endoscope channel system and the connecting seat for the spinal endoscope channel system expand the incision through the expansion liner under the connecting seat plate, increasing the space for subsequent surgical operations. At the same time, the guide slides and positioning cylinders on the left and right sides of the top surface of the locking seat plate, which can change angle and range, drive the endoscope and other instruments to move, thereby allowing for adjustments as needed for operations inside different incisions. The specific details are as follows:

[0021] 1. The rotating drive gear drives the meshing drive gear ring to rotate, and the rotating drive gear ring drives the meshing guide gear to move the guide rack during the rotation. At the same time, the moving guide rack drives the expansion liner fixedly connected below the inner lining to move inside the main endoscope channel and the spinal wound, thereby expanding the wound.

[0022] 2. The guide slide on the top surface of the locking seat plate drives the inner positioning cylinder seat to install. Then, the endoscope and illumination tube and other surgical instruments are inserted into the positioning guide groove inside the positioning cylinder seat, so that the endoscope and illumination tube and other surgical instruments are stably installed through the auxiliary endoscope channel and the main endoscope channel.

[0023] 3. Pull the positioning tooth plate outward to compress the return spring on the outer wall, and then manually rotate the unrestricted guide groove ring to change the operating angle of the guide slides on the left and right sides of its top. After the return spring drives the positioning tooth plate to reset and mesh with the guide groove ring, the guide slides and positioning cylinder seat are locked after the position is changed.

[0024] 4. Rotating the adjustment knob causes the internal guide thread rod to rotate, which in turn causes the guide sleeve connected to the inner end to rotate. At the same time, the guide sleeve slides and engages with the left and right sides of the guide slide block through the positioning sliders on the left and right sides, so that the guide sleeve drives the positioning cylinder seat fixedly connected to the inner end and the installed endoscope and other instruments to move.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-9 This invention provides a technical solution: a spinal endoscope channel system, including a connecting base plate 1 for positioning the spinal endoscope channel system, and a main endoscope channel 2 opened at the center of the connecting base plate 1, wherein an expansion cavity 3 is provided on the outer side of the connecting base plate 1; it also includes: a drive gear 6 rotatably mounted on the left side of the expansion cavity 3 inside the connecting base plate 1 via a bearing, and a drive gear ring 7 rotatably mounted inside the expansion cavity 3; a guide gear 10 rotatably mounted on the center of the expansion cavity 3 inside the connecting base plate 1 via a bearing at equal angles, and a guide rack 11 slidingly mounted on the interior of the expansion cavity 3 at equal angles; Figure 4-5 As shown, the drive gear 6 on the left side of the expansion cavity 3 inside the connecting base plate 1 is rotated by hand, which drives the meshing drive gear ring 7 to rotate. The rotating drive gear ring 7 drives the meshing guide gear 10 to drive the guide rack 11 (towards and outwards) to move during the rotation.

[0037] The drive gear ring 7 in the expansion cavity 3 inside the connecting base plate 1 is meshed with the outer wall of the left drive gear 6, and the inner wall of the drive gear ring 7 is meshed with the outer wall of the guide gear 10 arranged at equal angles. The upper outer wall of the guide gear 10, also arranged at equal angles, is meshed with the middle part of the guide rack 11. An expansion liner 12 is slidably arranged at equal angles below the connecting base plate 1, and the top ends of the expansion liner 12, arranged at equal intervals, are fixedly connected to the lower inner end of the guide rack 11, which is arranged at equal angles inside the connecting base plate 1. Figure 3-4As shown, the connecting plate 1 is placed on the surface of the spinal wound, ensuring that the expansion liner 12, which is set at the same angle below the connecting plate 1, is placed inside the wound. The moving guide rack 11 drives the expansion liner 12, which is fixedly connected below the inner tube, to move in the main endoscope channel 2 and inside the spinal wound, thereby expanding the wound.

[0038] A locking seat plate 4 for positioning the endoscope or illumination tube is fixedly installed on the top surface of the connecting seat plate 1, and a secondary endoscope channel 5 is opened at the center of the locking seat plate 4; a guide groove ring 13 is rotatably provided inside the locking seat plate 4, and a locking positioning ring 14 is fixedly installed inside the locking seat plate 4, and the upper and lower ends of the inner side of the locking positioning ring 14 are slidably connected to the outer ends of the positioning tooth plate 15, and the upper and lower positioning tooth plates 15 and the locking positioning ring 14 are connected to each other by a return spring 21; the upper and lower positioning tooth plates 15 inside the locking seat plate 4 are engaged with the inside of the guide groove ring 13, and the positioning tooth plates 15 can disengage from the guide groove ring 13 after movement, and the top surface of the guide groove ring 13 is fixedly connected to the bottom surface of the left and right guide slides 8; Figure 6-8 As shown, the positioning tooth plates 15 on the upper and lower sides inside the locking seat plate 4 are manually pulled outward, causing the return spring 21 on the outer wall to be compressed. After the movement, the spring 21 is disengaged from the guide groove ring 13 inside the locking seat plate 4. Then, the unrestricted guide groove ring 13 is manually rotated, thereby causing the guide slides 8 on the left and right sides of its top to change the operating angle.

[0039] Among them, guide slides 8 for positioning the endoscope or illumination tube are slidably arranged on the left and right sides of the top surface of the locking seat plate 4, and the outer ends of the left and right guide slides 8 are rotatably equipped with adjustment knobs 9 via bearings; the guide slides 8 are symmetrically arranged, and the guide thread rods 16 are rotatably equipped inside the guide slides 8 via bearings, and the outer ends of the guide thread rods 16 on both sides are fixedly connected to the rotating shaft of the adjustment knobs 9, and the inner ends of the guide thread rods 16 on both sides are threaded to the outer ends of the guide sleeves 17, and the inner ends of the guide sleeves 17 on both sides are slidably disposed outside the inner ends of the guide slides 8; Figure 6 , 9 As shown, manually rotating the adjustment knob 9 at the outer end of the guide slide 8 on both sides causes the internal guide thread rod 16 to rotate, which in turn causes the guide thread rod 16 to rotate together with the guide sleeve 17 connected to the inner end by the thread. At the same time, the guide sleeve 17 is slidably engaged with the left and right sides of the guide slide 8 by the positioning sliders 20 on both sides, so that the guide sleeve 17 drives the positioning sleeve seat 18 fixedly connected to the inner end and the installed endoscope and other instruments to move.

[0040] Working principle: Before using the spinal endoscope access system and its connector, the overall condition of the device must be checked to ensure it can function properly. Figure 1 - Figure 9 As shown, the drive gear 6 on the left side of the expansion cavity 3 inside the rotating connecting plate 1 drives the meshing drive gear ring 7 to rotate. The rotating drive gear ring 7 drives the meshing guide gear 10 to move the guide rack 11 (towards and outwards) during the rotation. At the same time, the moving guide rack 11 drives the expansion liner 12 fixedly connected below the inner core to move inside the main endoscope channel 2 and the spinal incision, thereby expanding the incision and increasing the space for subsequent surgical operations.

[0041] When installing the endoscope and illumination tube, the guide slide 8 on the top surface of the locking seat plate 4 drives the positioning cylinder seat 18 on the inner side to install. Then, the surgical instruments such as the endoscope and illumination tube are inserted into the positioning guide groove 19 inside the positioning cylinder seat 18, so that the surgical instruments such as the endoscope and illumination tube are stably installed through the auxiliary endoscope channel 5 and the main endoscope channel 2 to prevent displacement or falling off during the operation and cause medical accidents.

[0042] When adjusting the position of the guide slides 8 on the left and right sides and the positioning cylinder seat 18, pull the positioning tooth plate 15 outward to disengage it from the guide groove ring 13. Then, manually rotate the unrestricted guide groove ring 13 to change the operating angle of the guide slides 8 on the left and right sides at the top. After the return spring 21 drives the positioning tooth plate 15 to reset and re-engage with the guide groove ring 13, lock the guide slides 8 and the positioning cylinder seat 18 after the position is changed to prevent deviation during operation.

[0043] When adjusting the position of the endoscope and illumination tube inside the positioning sleeve 18, rotating the adjustment knob 9 causes the internal guide thread rod 16 to rotate. At the same time, the guide sleeve 17 is slidably engaged with the left and right sides of the guide slide block 8 through the positioning sliders 20 on the left and right sides. This allows the guide sleeve 17 to move the positioning sleeve 18 and the installed endoscope and other instruments that are fixedly connected to the inner end, thereby allowing for adjustment according to the needs of different wounds during operation.
