Description

Technical Field

[0001] The invention relates to the technical field of neurosurgery, in particular to a neurosurgery fixator. Background Art

[0002] Neurosurgery is generally performed on the head or spine, and the head needs to be prepared and the hair on it shaved during surgery. In some neurosurgery operations, the patient's head needs to be fixed and then pulled to facilitate the operation. Generally, a head ring and head pins are used together, and the top of the head pin is inserted into the "sweatband" area above the patient's head for fixation, and then the head ring is pulled with a traction device. However, it is generally not recommended to use head pins to fix the head for children. Some patients may need emergency surgery due to trauma from accidental accidents such as car accidents. The patient's face or head may have certain skin lesions and injuries. When using traditional methods to fix the head, it may be inconvenient to fix and pull the head because the patient's injury is in the "sweatband", which is more inconvenient.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-8 In an embodiment of the present invention, a neurosurgical fixator comprises: A base plate 100, a fixing mechanism 200 for tightly fitting the patient's head, two adjusting mechanisms 400 for adjusting the fixing mechanism 200, and an injection molding mechanism 300 for fixing the fixing mechanism 200 on the patient's head, the bottom surfaces of the two adjusting mechanisms 400 are respectively fixedly connected to the two ends of the top surface of the base plate 100, the fixing mechanism 200 is located between the two adjusting mechanisms 400, the fixing mechanism 200 includes a tube body 210, and the tube body 210 is an open structure at one end, a cutting groove 211 is opened on the outer wall of the tube body 210, and one end of the tube body 210 is fixedly connected to an internal threaded barrel 230, the internal threaded barrel 230 is a one-end sealed structure, and the injection molding mechanism 300 is used in conjunction with the fixing mechanism 200.

[0020] Specifically, the middle part of the outer wall of the tube body 210 is flat. The user can use double-sided tape to attach it to the flat bottom of the outer wall of the tube body 210, and then attach the tube body 210 to the patient's head after skin preparation to form appropriate patterns. The direction of the tube body 210 should be adhered to various parts of the patient's head according to the needs of the user, and away from the surgical area and the patient's head trauma and skin lesions. Then, the injection molding mechanism 300 is used to inject thermoplastic plastic into the tube body 210, and then the thermoplastic plastic solidifies and hardens, so that the patterns formed on the tube body 210 are shaped and fixed, so that the tube body 210 is connected to the patient's head as a whole, and then the adjustment mechanism 400 is used to move the patterns formed on the tube body 210 for traction or fixation, thereby traction or fixation of the patient's head, which is convenient for users to use. The tube body 210 is made of soft plastic.

[0021] Embodiment 1

[0022] like Figure 2-3 As shown, in this embodiment, a flow guide tube 220 is arranged inside the tube body 210, and one end of the flow guide tube 220 passes through the other end of the tube body 210 and is fixedly connected to the other end of the tube body 210, and the other end of the flow guide tube 220 is fixedly connected to one end of the internal threaded tube 230, and a connecting hole 232 is opened at one end of the internal threaded tube 230, and the interior of the connecting hole 232 is connected to the interior of the flow guide tube 220, and a connecting plate 221 is fixedly connected between the outer wall of the flow guide tube 220 and the inner wall of the tube body 210, a plurality of flow through holes 212 passing through the other end of the tube body 210 are opened at one end of the tube body 210, and a plurality of water injection holes 231 are opened at one end of the internal threaded tube 230, and the interior of any flow through hole 212 is connected to the interior of the adjacent water injection hole 231.

[0023] In this embodiment, by screwing the water pipe and the internal threaded tube 230 together, when the melted plastic is injected into the tube body 210 through the cutting groove 211, the cooling liquid is transported through the water pipe, so that the cooling liquid flows into the guide tube 220 through the connecting hole 232, and the cooling liquid can flow into the multiple flow holes 212 through the multiple water injection holes 231, so that the water flows through the guide tube 220 and the flow holes 212 to cool the plastic injected into the tube body 210 so that it hardens and solidifies, and then the cooling liquid can flow out from the flow holes 212 and the guide tube 220, so that the cooling liquid in the multiple flow holes 212 and the guide tube 220 always remains in a flowing state, and the temperature of the cooling liquid in the multiple flow holes 212 and the guide tube 220 is kept stable, and there is continuous water flowing inside the multiple flow holes 212, so that the overall temperature of the tube body 210 is relatively low, so that when the melted plastic is injected into the tube body 210, its temperature is not easy to affect the patient, and the patient is difficult to feel the high temperature.

[0024] like Figure 4-6 As shown, in this embodiment, the injection molding mechanism 300 includes: The box body 310, the bottom end of the fixed tube 320 passes through the top of the box body 310 and is fixedly connected to the top of the box body 310, the bottom end of the fixed tube 320 is located inside the box body 310, one end of the power box 330 is fixedly connected to the top surface of the box body 310, an air pump is arranged inside the power box 330, and the air outlet end of the air pump is connected to the inside of the box body 310, one end of the hose 340 is fixedly connected to the top of the fixed tube 320, the inside of the hose 340 is connected to the inside of the fixed tube 320, and one end of the holding tube 350 is fixedly sleeved with the other end of the hose 340.

[0025] In specific implementation, when in use, an electric heating device can be set in the box 310 to melt the plastic. The electric heating device is a prior art and will not be described in detail here. The melted plastic is stored in the box 310 in liquid form, and then the air pump is started to inject gas into the box 310, so that the gas squeezes the liquid plastic to flow out through the fixed tube 320, the hose 340 and the holding tube 350. The holding tube 350 can be covered with insulating cloth when in use, so that the user can hold it, thereby facilitating the use of the user.

[0026] like Figure 5-6 As shown, in the present embodiment, a copper rod 360 is provided at the other end of the holding tube 350, and a copper ring is fixedly sleeved on one end of the copper rod 360, and the outer wall of the copper ring is fixedly sleeved on the inner wall of the holding tube 350, and a plurality of circular through holes are opened at one end of the copper rod 360, and a hollow shell 370 is fixedly sleeved on the other end of the inner wall of the holding tube 350, and sleeve holes 371 are opened at both ends of the hollow shell 370, and the inner walls of the two sleeve holes 371 are fixedly sleeved on the outer wall of the copper rod 360, and a plurality of water pipes 372 are connected to one end of the hollow shell 370, and one end of the plurality of water pipes 372 passes through the holding tube 350 and is located outside the holding tube 350.

[0027] In a specific implementation, when the plastic in the box body 310 flows out from the holding tube 350, it can flow into the copper rod 360 and flow out through the multiple circular through holes. The copper rod 360 has a relatively thin diameter. When injecting plastic into the tube body 210, the copper rod 360 can be inserted into the cutting groove 211 to inject the plastic. When injecting plastic, part of the water pipe 372 can be connected to the pipeline, and the pipeline and part of the water pipe 372 can be used to inject a liquid flow with a temperature slightly lower than that of the melted plastic into the hollow shell 370, and the liquid flow is made to flow out from other water pipes 372, so that the inside of the hollow shell 370 is filled with liquid. The liquid flow remains in a flowing state, and the temperature of the liquid flow inside the hollow shell 370 is kept stable. The liquid flow inside the hollow shell 370 can exchange heat with the plastic flowing through the copper rod 360 through the copper rod 360, and the plastic is initially cooled to reduce the temperature of the plastic, but the plastic still flows in a liquid state, so that the temperature of the plastic entering the tube body 210 is reduced and it is easier to cool and harden after entering the tube body 210. The temperature of the copper rod 360 is maintained by the liquid flow inside the hollow shell 370, so as to prevent the plastic injected into the tube body 210 from solidifying at the outlet of the copper rod 360.

[0028] like Figure 5-6 As shown, in this embodiment, an arc-shaped cover 361 is provided at one end of the copper rod 360, and a circular hole is opened in the center of the outer arc surface of the arc-shaped cover 361, the inner wall of the circular hole is fixedly sleeved with the outer wall of the copper rod 360, and a plurality of clamping blocks 362 are fixedly connected at both ends of the arc-shaped cover 361, and two mirror-symmetrical clamping rails 240 are fixedly connected to the outer wall of the tube body 210, and any clamping block 362 is slidably clamped in the inside of the adjacent clamping rail 240.

[0029] In specific implementation, when in use, after the copper rod 360 is inserted into one end of the cutting groove 211, the arc-shaped cover 361 can cover a part of the cutting groove 211, and then the plastic is injected to prevent the plastic from flowing out of the cutting groove 211. After the plastic in the tube body 210 solidifies, the copper rod 360 can be moved and the plastic can be injected into other parts of the tube body 210 again, so that the newly injected plastic contacts and fuses with the solidified plastic in the tube body 210, and then the plastic is injected into various parts of the tube body 210 in turn, so that the plastic in the tube body 210 is connected as a whole. The arc-shaped cover 361 is made of copper, which can make the temperature of the copper rod 360 The plastic in the cutting groove 211 of the tube body 210 is transferred to the arc cover 361, so that part of the plastic in the cutting groove 211 of the tube body 210 is not easy to completely solidify and adheres to the arc cover 361. When in use, the user can insert the block 362 into the rail 240 and then slide the copper rod 360 to move it. After the plastic in the tube body 210 is injected, the copper rod 360 can be slid to injection-mold other parts of the tube body 210. After the arc cover 361 and the copper rod 360 are separated from the originally injected plastic, the fluidity of the plastic that has not been completely solidified in the originally injected plastic becomes poor and is not easy to flow out of the tube body 210. Then the plastic that has not been completely solidified will be completely solidified due to the temperature of the coolant.

[0030] like Figure 7-8 As shown, in this embodiment, the adjustment mechanism 400 includes: A screw rod 411 is rotatably connected between the two arms of the U-shaped frame 410, and the moving block 420 is located between the two arms of the U-shaped frame 410. A screw hole is opened on one side of the moving block 420, and the inner wall of the screw hole is screwed with the outer wall of the screw rod 411. A plurality of rollers 421 are rotatably connected between the two opposite inner walls of the moving block 420, and the plurality of rollers 421 are all in contact with the inner bottom surface of the U-shaped frame 410. The electric push rod 430 is fixedly connected to the top surface of the moving block 420, and the cylinder 440 is fixedly connected to the movable end of the electric push rod 430. The movable end of the cylinder 440 is fixedly connected to the U-shaped block 441, and a rotating rod 442 is rotatably connected between the two arms of the U-shaped block 441, and an embedded rod 443 is rotatably connected to the outer wall of the rotating rod 442.

[0031] During specific implementation, the two moving blocks 420 on the two adjustment mechanisms 400 are initially arranged diagonally with the center of the base plate 100 as the center, and the two screws 411 have opposite rotation directions. When plastic is injected into the tube body 210, the embedded rod 443 can be inserted into the tube body 210 and integrated with the plastic before the plastic is completely solidified. Then the user can rotate the two screws 411 and start the two electric push rods 430 and the two cylinders 440 to adjust the position of the patient's head and fix it, or perform traction.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, the embedded plate 444 is provided to ensure that the embedded rod 443 is firmly connected to the plastic.

[0034] like Figure 7-8 As shown, in this embodiment, one end of the embedded rod 443 is fixedly connected to the embedded plate 444, and the diameter of the embedded plate 444 is larger than the diameter of the embedded rod 443, one end of the screw rod 411 on the two adjustment mechanisms 400 passes through one arm of the adjacent U-shaped frame 410 and is fixedly sleeved with a pulley, a transmission belt is rotatably sleeved between the two pulleys, the other arm of a U-shaped frame 410 is fixedly connected to a motor box 450, and a driving motor is arranged inside the motor box 450, and the motor shaft of the driving motor is fixedly connected to the other end of the adjacent screw rod 411.

[0035] During specific implementation, the driving motor can be started to drive the two screw rods 411 to rotate synchronously in the same direction. Since the two screw rods 411 rotate in opposite directions, the two moving blocks 420 can be driven to move toward or away from each other when the two screw rods 411 rotate synchronously. When the embedded rod 443 is inserted into the unsolidified plastic in the tube body 210, the embedded plate 444 will be embedded in the plastic, so that the plastic can be stuck in the embedded plate 444 after solidification, so that the solidified plastic is firmly connected to the embedded rod 443, and the thermoplastic plastic can be reused. After use, the user can use a medical hand saw or other equipment to saw off the solidified plastic and remove it from the tube body 210, and then put it back into the box body 310 for recycling.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
