The aspirator is mainly used to remove bleeding, exudate, pus, and contents of chest organs during surgery to make the surgery clean and reduce the chance of contamination. The principle of the aspirator is very simple, that is, a negative pressure state of the suction head is created through a certain method, so that the atmospheric pressure will squeeze the material outside the suction head into the suction head, thereby achieving the "suction" effect.

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.

[0042] like Figures 1 to 12 As shown, an embodiment of the present invention provides a spinal cord surgery spinal nerve injury prevention suction device, comprising a collecting bottle 101, the upper end of the collecting bottle 101 is threadedly connected to a sealing cover 102, the top of the sealing cover 102 is fixedly connected to a connector 103, the inner wall of the connector 103 is fixedly connected to a connecting tube 104, the upper end of the sealing cover 102 is fixedly connected to a liquid inlet pipe 105, the inner wall of the liquid inlet pipe 105 is provided with a hose 106, one end of the hose 106 is provided with a first hollow handle 107, one side of the first hollow handle 107 is provided with a second hollow handle 108, and the second hollow handle 10 8 is fixedly connected to one side of a hollow rod 109, and a suction head 110 is sleeved on one side of the hollow rod 109, and the suction head 110 is made of soft material, and a fixing ring 111 is fixedly connected to the outer surface of the suction head 110, and a plurality of connecting ropes 112 are fixedly connected to one side of the fixing ring 111, and the plurality of connecting ropes 112 are all arranged in a circle, and the plurality of connecting ropes 112 are slidably passed through the hollow rod 109 and the second hollow handle 108, and a semicircular block 113 is fixedly connected to one side of the plurality of connecting ropes 112, and a limiting component for limiting the connecting ropes 112 is provided on the second hollow handle 108.

[0043] When it is necessary to absorb the liquid in the narrow area of ​​the inner wall of the spinal cord, the staff connects the connecting tube 104 to the negative pressure device, and then the staff pulls one of the semicircular blocks 113, and the semicircular block 113 drives the connecting rope 112 to slide in the hollow rod 109 and the second hollow handle 108, and the connecting rope 112 drives the fixing ring 111 to rotate, and the fixing ring 111 rotates while adjusting the angle of the suction head 110, so that the suction head 110 contacts the liquid in the narrow area of ​​the inner wall of the spinal cord, and the connecting rope 112 is restricted by the limiting component to prevent the suction head 110 from being reset, and the suction head 110 helps to reduce the friction and damage of the device to the spinal nerves. Subsequently, the liquid in the narrow area of ​​the inner wall of the spinal cord is absorbed by the negative pressure device, and the liquid enters the hollow rod 109 through the suction head 110, and is then sucked into the collection bottle 101 through the second hollow handle 108, the first hollow handle 107 and the hose 106 for collection, thereby improving the clarity of the staff's field of vision during the operation.

[0044] like Figure 5 As shown, the limiting assembly includes a circular plate 201, which is fixedly connected to the outer surface of the second hollow handle 108, and the connecting rope 112 slides through the circular plate 201. An elastic ring 202 is provided on the outer surface of the circular plate 201, and a circular groove 203 that cooperates with the elastic ring 202 is opened on the circular plate 201.

[0045] When it is necessary to restrict the connecting rope 112, 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 restrict the connecting rope 112, and the elastic ring 202 generates friction when in contact with the connecting rope 112. This friction helps prevent the connecting rope 112 from sliding freely on the annular plate 201, thereby enhancing the restraining effect on the connecting rope 112.

[0046] like Figure 6 As shown, a plurality of pressure relief holes 204 are provided on the second hollow handle 108, and the plurality of pressure relief holes 204 are all connected to the inner wall of the second hollow handle 108, and the inner wall of the plurality of pressure relief holes 204 is slidably connected with a sealing rod 205, and the sealing rod 205 slides through the second hollow handle 108, and a sealing block 206 is fixedly connected to one side of the plurality of sealing rods 205 close to each other, and a pull block 207 is fixedly connected to the other side of the sealing rod 205, and a first spring 208 is fixedly connected between the outer surface of the second hollow handle 108 and the pull block 207, and the first spring 208 is sleeved on the outer side of the sealing rod 205, and a plurality of limit rods 209 are symmetrically fixedly connected to the outer surface of the second hollow handle 108, and the pull block 207 is slidably connected to two adjacent pull blocks 207, and the top of the limit rod 209 is fixedly connected to a limit plate 210.

[0047] When it is necessary to reduce direct contact and pressure on the spinal nerves, the pull block 207 is pulled upward, and the pull block 207 drives the sealing rod 205 and the sealing block 206 to slide upward along the length direction of the limit rod 209. The first spring 208 is stretched, and when the pull block 207 slides to contact the bottom end of the limit plate 210, the pull block 207 drives the sealing rod 205 to leave the pressure relief hole 204, and the pressure relief hole 204 reduces the influence of the negative pressure generated by the device during the suction process on the spinal nerves. 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-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.

[0048] like Figure 6As shown, a threaded rod 211 is threadedly connected to one side of the pull block 207, a knob 212 is fixedly connected to one side of the threaded rod 211, and a threaded hole 213 cooperating with the threaded rod 211 is formed at the upper end of the right limiting rod 209.

[0049] When it is necessary to limit the pull block 207, the pull block 207 is pulled upward, and the pull block 207 drives the sealing rod 205 and the sealing block 206 to slide. The first spring 208 is stretched, and when the pull block 207 slides to contact the bottom end of the limit plate 210, the knob 212 is turned, and the knob 212 drives the threaded rod 211 to rotate, and the threaded rod 211 is screwed into the threaded hole 213 on the limit rod 209, so as to limit the pull block 207 and prevent the sealing rod 205 from being inserted into the pressure reducing hole 204, thereby blocking the pressure reducing hole 204.

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

[0051] When the length of the second hollow handle 108 needs to be adjusted, the screw block 218 is turned, and the screw block 218 drives the rotating shaft 217 to rotate in the shell 216, and the rotating shaft 217 drives the gear 219 to rotate, and the gear 219 drives the rack plate 215 to slide, and the rack plate 215 drives the connecting column 214 to slide outward in the first hollow handle 107, and the connecting column 214 drives the second hollow handle 108 to extend, and the length of the second hollow handle 108 is adjusted. After the adjustment is completed, the rotating shaft 217 is locked by the locking assembly to prevent the rotating shaft 217 from rotating at will.

[0052] like Figure 8As shown, the locking assembly includes a rectangular sleeve 220, which is fixedly connected to the outer surface of the first hollow handle 107, and the inner wall of the rectangular sleeve 220 is slidably connected with a sliding block 221, and a second spring 222 is fixedly connected between the inner wall of the rectangular sleeve 220 and the sliding block 221, and the front end of the sliding block 221 is fixedly connected with an arc block 223, and the arc block 223 slides through the front end of the rectangular sleeve 220, and one side of the sliding block 221 is fixedly connected with a connecting block 224, and the connecting block 224 slides through the left end of the rectangular sleeve 220, and the bottom end of the connecting block 224 is fixedly connected with a latch 225, and the outer surface of the rotating shaft 217 is fixedly connected with a circular plate 226, and a plurality of slots 227 that cooperate with the latch 225 are opened on the circular plate 226.

[0053] When it is necessary to lock the rotating shaft 217, the arc block 223 is pulled upward, and the arc block 223 drives the sliding block 221 to slide in the rectangular sleeve 220, the second spring 222 is compressed, the sliding block 221 drives the connecting block 224 to slide, and the connecting block 224 drives the pin 225 to leave the slot 227 on the circular plate 226. Then, the screw block 218 is twisted, and the screw block 218 drives the gear 219 and the circular plate 226 to rotate, and the length of the second hollow handle 108 is adjusted. After the adjustment is completed, the arc block 223 is released, the second spring 222 rebounds, the sliding block 221 drives the connecting block 224, and the connecting block 224 drives the pin 225 to be inserted into the slot 227 on the circular plate 226, thereby locking the rotating shaft 217 to prevent the rotating shaft 217 from rotating at will.

[0054] like Fig.10 As shown, the inner wall of the hollow rod 109 is symmetrically fixedly connected with a fixing block 228 at the front and back, a connecting rod 229 is rotatably connected between the two fixing blocks 228, one end of the connecting rod 229 is rotatably passed through the fixing block 228 and the front end of the hollow rod 109, a shifting 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 the liquid blocked in the hollow rod 109 needs to be cleared, the block 230 is moved back and forth, the block 230 drives the connecting rod 229 to rotate, and the connecting rod 229 drives the clearing rod 231 to rotate, so as to clear the liquid blocked in the hollow rod 109 and make the suction process smoother.

[0056] like Fig.11 As shown, the outer surface of the hollow rod 109 is fixedly connected to a limiting block 232 , a U-shaped opening 233 is formed on the limiting block 232 , and a rubber block 234 is fixedly connected to the inner wall of the U-shaped opening 233 symmetrically in front and back.

[0057] When the dredging rod 231 needs to be reset and restricted, the block 230 is pushed upward and moved into the U-shaped opening 233. When the block 230 contacts the rubber block 234, the rubber block 234 is compressed. When the block 230 completely passes through the rubber block 234, the rubber block 234 rebounds to restrict the block 230 and avoid affecting the suction of the liquid.

[0058] like Fig.12 As shown, a mounting 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 mounting block 235 , and a conical shell 237 is fixedly connected to one side of the mounting block 235 .

[0059] By providing the lighting lamp 236, the lighting lamp 236 can illuminate the surgical area, allowing the staff to see the surgical site more clearly, thereby reducing the risk of misoperation, and the conical shell 237 can limit the scattering range of light, so that the light can be more focused on the area that needs to be illuminated, thereby improving the lighting efficiency.

[0060] like Figure 7 As shown, a T-shaped slider 238 is symmetrically fixedly connected to the outer surface of the connecting column 214 up and down, and a T-shaped sliding groove 239 that cooperates with the T-shaped slider 238 is opened on the first hollow handle 107.

[0061] By providing a T-shaped slider 238 and a T-shaped slot 239, when the connecting column 214 is sliding, the connecting column 214 can drive the T-shaped slider 238 to slide in the T-shaped slot 239. The T-shaped slot 239 can guide and limit the T-shaped slider 238 and the connecting column 214. The T-shaped slider 238 slides in the T-shaped slot 239, which 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 tube 104 to the negative pressure device, and then the staff pulls one of the semicircular blocks 113, and the semicircular block 113 drives the connecting rope 112 to slide in the hollow rod 109 and the second hollow handle 108, and the connecting rope 112 drives the fixing ring 111 to rotate, and the fixing ring 111 rotates while adjusting the angle of the suction head 110, so that the suction head 110 contacts the liquid in the narrow area of ​​the inner wall of the spinal cord, and then the elastic ring 202 is slid into the circular groove 203 on the circular ring plate 201, and the elastic ring 202 can limit the connecting rope 112 under the elastic force of the elastic ring 202, and the elastic ring 202 contacts the connecting rope 112 to generate friction, and this friction It helps to prevent the connecting rope 112 from sliding randomly on the circular plate 201, enhances the restraining effect on the connecting rope 112, and prevents the suction head 110 from resetting. Subsequently, the liquid in the narrow area of ​​the inner wall of the spinal cord is sucked out by the negative pressure device, and 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 handle 108, the first hollow handle 107 and the hose 106 for collection. The operating area can be illuminated by the lighting 236 on the hollow rod 109, so that the staff can see the operating site more clearly, thereby reducing the risk of misoperation, and the conical shell 237 can limit the scattering range of light, so that the light can be more focused on the area that needs to be illuminated, thereby improving the lighting efficiency and enabling the staff to The field of vision is clearer during the operation. In the process of sucking out the liquid, the dial block 230 is moved back and forth, and the dial block 230 drives the connecting rod 229 to rotate, and the connecting rod 229 drives the dredging rod 231 to rotate, so as to dredge the liquid blocked in the hollow rod 109, so as to make the suction process smoother. After the dredging is completed, the dial block 230 is moved upward to 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 to avoid affecting the suction of the liquid. When it is necessary to reduce the direct contact and compression of the spinal nerves, the pull block 207 is pulled upward, and the pull block 207 drives the sealing rod 205 and the sealing block 206 along The limiting rod 209 slides upward in the length direction, the first spring 208 stretches, and the pull block 207 drives the sealing rod 205 to leave the pressure relief hole 204. When the pull block 207 slides to contact the bottom end of the limiting plate 210, the knob 212 is turned, and 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 limit the pull block 207. The pressure relief hole 204 reduces the negative pressure generated by the device during the suction process on the spinal nerves. 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-stretched or damaged when removing blood, tissue fragments or other foreign matter. When the length of the second hollow handle 108 needs to be adjusted,The arc block 223 is pulled upward, and the arc block 223 drives the sliding block 221 to slide in the rectangular sleeve 220. The second spring 222 is compressed, and the sliding block 221 drives the connecting block 224 to slide. The connecting block 224 drives the latch 225 to leave the slot 227 on the circular plate 226. Then, the screw block 218 is twisted, and the screw block 218 drives the rotating shaft 217 and the circular plate 226 to rotate in the housing 216. The rotating shaft 217 drives the gear 219 to rotate, and the gear 219 drives the rack plate 215 to slide. The rack plate 215 drives the connecting column 214 to slide outward in the first hollow handle 107. During the sliding process, the connecting column 214 brings The movable T-shaped slider 238 slides in the T-shaped slide groove 239, and the T-shaped slide groove 239 can guide and limit the T-shaped slider 238 and the connecting column 214, thereby improving the stability of the connecting column 214 during movement. The connecting column 214 drives the second hollow handle 108 to extend, and the length of the second hollow handle 108 is adjusted. After the adjustment is completed, the arc block 223 is released, the second spring 222 rebounds, the sliding block 221 drives the connecting block 224, and the connecting block 224 drives the latch 225 to be inserted into the slot 227 on the circular plate 226, thereby locking the rotating shaft 217 to prevent the rotating shaft 217 from rotating at will.
