Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly, to a spinal cord surgery aspirator for preventing spinal cord nerve injury. Background Art

[0002] In spinal surgery, such as cervical, thoracic and lumbar surgeries, it is often necessary to aspirate the liquid in the surgical area. The aspirator is mainly used to suck out the bleeding, exudate, pus, and contents in the thoracic viscera during the surgery, so as to clear the surgery and reduce the chance of contamination. The principle of the aspirator is very simple, that is, to create a negative pressure state at the suction head through a certain method, so that the atmosphere will squeeze the substances outside the suction head towards the suction head, thus completing the "aspiration" effect.

[0003] During the use of the existing spinal cord nerve injury prevention aspirator, due to its limited scope of application, it is inconvenient for the staff to aspirate the liquid in the narrow area close to the inner wall of the spinal cord, so that the blood, irrigation fluid or other liquids accumulated there cannot be effectively removed. This situation may not only affect the clarity of the surgical field, but also increase the operation time and complexity, and even increase the risk of postoperative infection or spinal cord nerve injury due to the remaining liquid.

[0016] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0017] In the above solution, by providing a connecting rope and an elastic ring, when it is necessary to suck the liquid in the narrow area of the spinal cord inner wall, one of the semi-circular blocks is pulled. The semi-circular block drives the connecting rope to slide in the hollow rod and the second hollow grip. The connecting rope drives the fixed ring to rotate. While the fixed ring rotates, the angle of the suction head is adjusted so that the suction head contacts the liquid in the narrow area of the spinal cord inner wall. Then, the elastic ring is slid and the elastic ring is slid into the circular ring groove on the circular ring plate. Under the elastic force of the elastic ring, the elastic ring can limit the connecting rope to prevent the suction head from resetting. Subsequently, the liquid in the narrow area of the spinal cord inner wall is sucked by a negative pressure device. The liquid enters the hollow rod through the suction head, and then is sucked into the collection bottle through the second hollow grip, the first hollow grip and the hose for collection. Moreover, the suction head helps to reduce the friction and damage of the device to the spinal cord nerves, thereby improving the clarity of the field of vision of the staff during the operation.

[0018] By providing a sealing rod, when it is necessary to reduce direct contact and pressure on the spinal nerves, first release the restriction on the pulling block, pull the pulling block upward, the pulling block drives the sealing rod and the sealing block to slide upward along the length direction of the limiting rod, the first spring is stretched, the pulling block drives the sealing rod to leave the pressure relief hole, and when the pulling block is slid to contact the bottom end of the limiting plate, the knob is turned, the knob drives the threaded rod to rotate, and the threaded rod is screwed into the threaded hole on the limiting rod to restrict the pulling block, and the negative pressure generated by the device during the suction process on the spinal nerves is reduced through the pressure relief hole. By reasonably controlling the pressure and suction range of the device, the pressure relief hole can ensure that the spinal nerves will not be over-stretched or damaged when removing blood, tissue fragments or other foreign matter, thereby improving the efficiency and safety of the operation and promoting postoperative recovery;

[0019] By providing a connecting column, when it is necessary to adjust the length of the second hollow handle, first release the restriction on the circular plate, twist the twist block, the twist block drives the rotating shaft to rotate in the shell, the rotating shaft drives the gear to rotate, the gear drives the rack plate to slide, the rack plate drives the connecting column to slide outward in the first hollow handle, the connecting column drives the second hollow handle to extend, and the length of the second hollow handle is adjusted. After the adjustment is completed, release the arc block, the second spring rebounds, the sliding block drives the connecting block, and the connecting block drives the pin to be inserted into the slot on the circular plate, locking the rotating shaft to prevent the rotating shaft from rotating at will, so as to facilitate the staff to hold the first hollow handle and the second hollow handle;

[0020] By providing a dredging rod, when it is necessary to dredge the liquid blocked in the hollow rod, first release the restriction on the shifting block, then move the shifting block back and forth, the shifting block drives the connecting rod to rotate, and the connecting rod drives the dredging rod to rotate, so as to dredge the liquid blocked in the hollow rod, making the suction process smoother. After dredging, push the shifting block upwards and move it into the U-shaped opening. When the shifting block contacts the rubber block, the rubber block is compressed. When the shifting block completely passes through the rubber block, the rubber block rebounds to restrict the shifting block to avoid affecting the suction of the liquid.

[0042] As Figures 1 to 12 shown, an aspirator for preventing spinal cord nerve injury in spinal cord surgery according to an embodiment of the present invention includes a collection bottle 101. The upper end of the collection bottle 101 is threadedly connected with a sealing cap 102. The top end of the sealing cap 102 is fixedly connected with a connecting head 103. The inner wall of the connecting head 103 is fixedly connected with a connecting pipe 104. The upper end of the sealing cap 102 is fixedly connected with a liquid inlet pipe 105. A hose 106 is arranged on the inner wall of the liquid inlet pipe 105. One end of the hose 106 is provided with a first hollow grip 107. A second hollow grip 108 is arranged on one side of the first hollow grip 107. A hollow rod 109 is fixedly connected to one side of the second hollow grip 108. A suction head 110 is sleeved on one side of the hollow rod 109. The suction head 110 is made of a soft material. A fixing ring 111 is fixedly connected to the outer surface of the suction head 110. A plurality of connecting ropes 112 are fixedly connected to one side of the fixing ring 111. The plurality of connecting ropes 112 are all arranged in a circle. The plurality of connecting ropes 112 all slide through the hollow rod 109 and the second hollow grip 108. A semi-circular block 113 is fixedly connected to one side of each of the plurality of connecting ropes 112. A limiting component for limiting the connecting ropes 112 is arranged on the second hollow grip 108.

[0043] When it is necessary to suck out the liquid in the narrow area of the spinal cord inner wall, the staff connects the connecting pipe 104 with a negative pressure device. Subsequently, the staff pulls one of the semi-circular blocks 113. The semi-circular block 113 drives the connecting rope 112 to slide in the hollow rod 109 and the second hollow grip 108. The connecting rope 112 drives the fixing ring 111 to rotate. While the fixing ring 111 rotates, the angle of the suction head 110 is adjusted so that the suction head 110 contacts the liquid in the narrow area of the spinal cord inner wall. The connecting rope 112 is restricted by the limiting component to prevent the suction head 110 from resetting, and the suction head 110 helps to reduce the friction and damage of the device to the spinal cord nerves. Subsequently, the liquid in the narrow area of the spinal cord inner wall is sucked out through the negative pressure device. The liquid enters the hollow rod 109 through the suction head 110, and then is sucked into the collection bottle 101 through the second hollow grip 108, the first hollow grip 107 and the hose 106 for collection, thereby improving the clarity of the staff's vision during the operation.

[0044] As shown Figure 5 in the figure, the limiting component includes an annular plate 201, the annular plate 201 is fixedly connected to the outer surface of the second hollow grip 108, the connecting rope 112 slides through the annular plate 201, an elastic ring 202 is arranged on the outer surface of the annular plate 201, and an annular groove 203 that cooperates with the elastic ring 202 is formed on the annular plate 201.

[0045] When it is necessary to limit the connecting rope 112, slide the elastic ring 202 and slide the elastic ring 202 into the annular groove 203 on the annular plate 201. Under the elastic force of the elastic ring 202, the elastic ring 202 can limit the connecting rope 112, and the elastic ring 202 contacts the connecting rope 112 to generate friction. This friction helps to prevent the connecting rope 112 from sliding randomly on the annular plate 201, enhancing the binding effect on the connecting rope 112.

[0046] As shown Figure 6 in the figure, a plurality of pressure relief holes 204 are formed in the second hollow grip 108, and the plurality of pressure relief holes 204 communicate with the inner wall of the second hollow grip 108. A sealing rod 205 is slidably connected to the inner walls of the plurality of pressure relief holes 204. The sealing rod 205 slides through the second hollow grip 108. Sealing blocks 206 are fixedly connected to the sides of the plurality of sealing rods 205 close to each other. A pull block 207 is fixedly connected to the other side of the sealing rod 205. A first spring 208 is fixedly connected between the outer surface of the second hollow grip 108 and the pull block 207. The first spring 208 is sleeved on the outer side of the sealing rod 205. A plurality of limiting rods 209 are symmetrically and fixedly connected to the left and right sides of the outer surface of the second hollow grip 108. The pull block 207 is slidably connected to the adjacent two pull blocks 207, and a limiting plate 210 is fixedly connected to the top of the limiting rod 209.

[0047] When it is necessary to reduce the direct contact and compression on the spinal nerves, pull up the pull block 207. The pull block 207 drives the sealing rod 205 and the sealing block 206 to slide upward along the length direction of the limiting rod 209, and the first spring 208 is stretched. When the pull block 207 slides to contact the bottom end of the limiting plate 210, the pull block 207 drives the sealing rod 205 to leave the pressure relief hole 204. By means of the pressure relief hole 204, the influence of the negative pressure generated during the suction process of the device on the spinal nerves can be reduced. By reasonably controlling the pressure and suction range of the device, the pressure relief hole 204 can ensure that the spinal nerves will not be over-pulled or damaged when clearing blood, tissue fragments or other foreign objects, thereby improving the surgical efficiency and safety and promoting postoperative recovery.

[0048] As shown Figure 6As shown, one side of the pulling block 207 is threadedly connected to a threaded rod 211. One side of the threaded rod 211 is fixedly connected to a knob 212. At the upper end of the right limiting rod 209, a threaded hole 213 that cooperates with the threaded rod 211 is provided.

[0049] When it is necessary to restrict the pulling block 207, pull up the pulling block 207. The pulling block 207 drives the sealing rod 205 and the sealing block 206 to slide, and the first spring 208 stretches. When the pulling block 207 slides to contact the bottom end of the limiting plate 210, turn the knob 212. The knob 212 drives the threaded rod 211 to rotate, and screw the threaded rod 211 into the threaded hole 213 on the limiting rod 209 to restrict the pulling block 207 and prevent the sealing rod 205 from being inserted into the pressure relief hole 204 to block the pressure relief hole 204.

[0050] As Figure 7 As shown, one side of the second hollow grip 108 is fixedly connected to a connecting column 214. The connecting column 214 is slidably connected to the inner wall of the first hollow grip 107. One end of the hose 106 is fixedly connected to the connecting column 214. The outer surface of the first hollow grip 107 is fixedly connected to a rack plate 215. The outer surface of the first hollow grip 107 is fixedly connected to a housing 216. The inner wall of the housing 216 is rotatably connected to a rotating shaft 217. The rotating shaft 217 rotates through the upper end of the housing 216. The top end of the rotating shaft 217 is fixedly connected to a screwing block 218. The outer surface of the rotating shaft 217 is fixedly connected to a gear 219. The gear 219 meshes with the rack plate 215. A locking assembly for locking the rotating shaft 217 is provided on the first hollow grip 107.

[0051] When it is necessary to adjust the length of the second hollow grip 108, turn the screwing block 218. The screwing block 218 drives the rotating shaft 217 to rotate in the housing 216. The rotating shaft 217 drives the gear 219 to rotate. The gear 219 drives the rack plate 215 to slide. The rack plate 215 drives the connecting column 214 to slide outwards in the first hollow grip 107. The connecting column 214 drives the second hollow grip 108 to extend to adjust the length of the second hollow grip 108. After the adjustment is completed, lock the rotating shaft 217 through the locking assembly to prevent the rotating shaft 217 from rotating randomly.

[0052] As Figure 8As shown, the locking component includes a rectangular sleeve 220 fixedly connected to the outer surface of the first hollow grip 107. A sliding block 221 is slidably connected to the inner wall of the rectangular sleeve 220. A second spring 222 is fixedly connected between the inner wall of the rectangular sleeve 220 and the sliding block 221. The front end of the sliding block 221 is fixedly connected to an arc-shaped block 223 which slidably penetrates through the front end of the rectangular sleeve 220. A connecting block 224 is fixedly connected to one side of the sliding block 221 and slidably penetrates through the left end of the rectangular sleeve 220. A latch 225 is fixedly connected to the bottom end of the connecting block 224. A circular plate 226 is fixedly connected to the outer surface of the rotating shaft 217, and a plurality of slots 227 cooperating with the latch 225 are formed in the circular plate 226.

[0053] When it is necessary to lock the rotating shaft 217, pull the arc-shaped block 223 upward. The arc-shaped block 223 drives the sliding block 221 to slide within the rectangular sleeve 220, compressing the second spring 222. The sliding block 221 drives the connecting block 224 to slide, and the connecting block 224 drives the latch 225 to leave the slot 227 on the circular plate 226. Subsequently, turn the turning block 218, which drives the gear 219 and the circular plate 226 to rotate, to adjust the length of the second hollow grip 108. After the adjustment is completed, release the arc-shaped block 223. The second spring 222 rebounds, the sliding block 221 drives the connecting block 224, and the connecting block 224 drives the latch 225 to insert into the slot 227 on the circular plate 226 to lock the rotating shaft 217 and prevent the rotating shaft 217 from rotating randomly.

[0054] As Figure 10 shown, fixed blocks 228 are symmetrically and fixedly connected to the front and rear inner walls of the hollow rod 109. A connecting rod 229 is rotatably connected between the two fixed blocks 228. One end of the connecting rod 229 rotatably penetrates through the front ends of the fixed block 228 and the hollow rod 109. A dialing block 230 is fixedly connected to the front end of the connecting rod 229, and three dredging rods 231 are fixedly connected to the outer surface of the connecting rod 229.

[0055] When it is necessary to dredge the liquid blocked in the hollow rod 109, dial the dialing block 230 back and forth. The dialing block 230 drives the connecting rod 229 to rotate, and the connecting rod 229 drives the dredging rods 231 to rotate to dredge the liquid blocked in the hollow rod 109 and make the suction process smoother.

[0056] As Figure 11 shown, a limiting block 232 is fixedly connected to the outer surface of the hollow rod 109. A U-shaped opening 233 is formed in the limiting block 232, and rubber blocks 234 are symmetrically and fixedly connected to the front and rear inner walls of the U-shaped opening 233.

[0057] When it is necessary to reset and limit the dredging rod 231, the dial block 230 is toggled upward and moved into the U-shaped opening 233. When the dial block 230 contacts the rubber block 234, the rubber block 234 is compressed. When the dial block 230 completely passes through the rubber block 234, the rubber block 234 rebounds to limit the dial block 230 and prevent it from affecting the suction of the liquid.

[0058] As Figure 12 shown, an installation block 235 is fixedly connected to the outer surface of the hollow rod 109. A lighting lamp 236 is arranged in the middle of the installation block 235. A conical shell 237 is fixedly connected to one side of the installation block 235.

[0059] By providing the lighting lamp 236, the lighting lamp 236 can illuminate the surgical area, enabling the staff to see the surgical site more clearly, thereby reducing the risk of misoperation. And through the conical shell 237, the scattering range of the light can be limited, making the light more focused on the area to be illuminated, thereby improving the lighting efficiency.

[0060] As Figure 7 shown, T-shaped sliders 238 are symmetrically and fixedly connected to the upper and lower outer surfaces of the connecting column 214. T-shaped sliding grooves 239 that cooperate with the T-shaped sliders 238 are formed in the first hollow grip 107.

[0061] By providing the T-shaped sliders 238 and the T-shaped sliding grooves 239, when the connecting column 214 slides, the connecting column 214 can drive the T-shaped sliders 238 to slide in the T-shaped sliding grooves 239. The T-shaped sliding grooves 239 can play a guiding and limiting role for the T-shaped sliders 238 and the connecting column 214. The T-shaped sliders 238 sliding in the T-shaped sliding grooves 239 can also improve the stability of the connecting column 214 during movement.

[0062] The working process provided by the present invention is as follows:

[0063] When the present invention is in use, the staff connects the connecting pipe 104 to a negative pressure device. Subsequently, the staff pulls one of the semi-circular blocks 113, and the semi-circular block 113 drives the connecting rope 112 to slide within the hollow rod 109 and the second hollow grip 108. The connecting rope 112 drives the fixed ring 111 to rotate. While the fixed ring 111 rotates, the angle of the suction head 110 is adjusted so that the suction head 110 contacts the liquid in the narrow area of the spinal cord inner wall. Subsequently, the elastic ring 202 is slid, and the elastic ring 202 is slid into the circular ring groove 203 on the circular ring plate 201. Under the elastic force of the elastic ring 202, the elastic ring 202 can restrict the connecting rope 112, and the elastic ring 202 contacts the connecting rope 112 to generate frictional force. This frictional force helps to prevent the connecting rope 112 from sliding randomly on the circular ring plate 201, enhancing the binding effect on the connecting rope 112 and preventing the suction head 110 from resetting. Subsequently, the liquid in the narrow area of the spinal cord inner wall is sucked out by the negative pressure device. The liquid enters the hollow rod 109 through the suction head 110, and then is sucked into the collection bottle 101 through the second hollow grip 108, the first hollow grip 107, and the hose 106 for collection. The lighting lamp 236 on the hollow rod 109 can illuminate the surgical area, enabling the staff to see the surgical site more clearly, thereby reducing the risk of misoperation. And through the conical shell 237, the scattering range of the light can be restricted, making the light shine more focused on the area to be illuminated, thereby improving the lighting efficiency and making the staff's vision clearer during the operation. During the process of sucking the liquid, the dial block 230 is toggled back and forth. The dial block 230 drives the connecting rod 229 to rotate, and the connecting rod 229 drives the dredging rod 231 to rotate to dredge the blocked liquid in the hollow rod 109, making the suction process smoother. After the dredging is completed, the dial block 230 is toggled upward and the dial block 230 is toggled into the U-shaped opening 233. When the dial block 230 contacts the rubber block 234, the rubber block 234 is compressed. When the dial block 230 completely passes through the rubber block 234, the rubber block 234 rebounds to restrict the dial block 230 and avoid affecting the suction of the liquid. When it is necessary to reduce the direct contact and compression on the spinal cord nerve, the pull block 207 is pulled upward. The pull block 207 drives the sealing rod 205 and the sealing block 206 to slide upward along the length direction of the limiting rod 209. The first spring 208 is stretched. The pull block 207 drives the sealing rod 205 to leave the decompression hole 204. When the pull block 207 slides to contact the bottom end of the limiting plate 210, the knob 212 is rotated. The knob 212 drives the threaded rod 211 to rotate, and the threaded rod 211 is screwed into the threaded hole 213 on the limiting rod 209 to restrict the pull block 207. Through the decompression hole 204, the influence of the negative pressure generated during the suction process of this device on the spinal cord nerve is reduced. By reasonably controlling the pressure and suction range of this device, the decompression hole 204 can ensure that when clearing blood, tissue fragments or other foreign objects, the spinal cord nerve will not be overly pulled or damaged. When it is necessary to adjust the length of the second hollow grip 108,Pull the arc-shaped block 223 upward. The arc-shaped block 223 drives the sliding block 221 to slide within the rectangular sleeve 220, compressing the second spring 222. The sliding block 221 drives the connecting block 224 to slide, and the connecting block 224 drives the bolt 225 to leave the slot 227 on the circular plate 226. Subsequently, turn the turning block 218. The turning block 218 drives the rotating shaft 217 and the circular plate 226 to rotate within the housing 216. The rotating shaft 217 drives the gear 219 to rotate. The gear 219 drives the rack plate 215 to slide. The rack plate 215 drives the connecting column 214 to slide outward within the first hollow grip 107. During the sliding process of the connecting column 214, it drives the T-shaped slider 238 to slide within the T-shaped chute 239. The T-shaped chute 239 can guide and limit the T-shaped slider 238 and the connecting column 214, improving the stability of the connecting column 214 during movement. The connecting column 214 drives the second hollow grip 108 to extend, adjusting the length of the second hollow grip 108. After the adjustment is completed, release the arc-shaped block 223. The second spring 222 rebounds. The sliding block 221 drives the connecting block 224, and the connecting block 224 drives the bolt 225 to insert into the slot 227 on the circular plate 226, locking the rotating shaft 217 to prevent the rotating shaft 217 from rotating randomly.
