Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an automatic regulating hydrocephalus shunt device. Background Technology

[0002] Hydrocephalus is a disease caused by an obstruction in the production, circulation, or absorption of cerebrospinal fluid, leading to abnormal accumulation of cerebrospinal fluid in the ventricular system or subarachnoid space. This results in ventricular enlargement and increased intracranial pressure, which in turn causes symptoms such as headache, vomiting, visual impairment, and cognitive and motor dysfunction. To facilitate the shunting of hydrocephalus, an automatic regulating hydrocephalus shunt device is needed.

[0003] The automatic adjustable hydrocephalus shunt device is a medical device that monitors intracranial pressure in real time through a pressure sensor and automatically adjusts the cerebrospinal fluid drainage rate using an electronically controlled valve. It can automatically adjust the shunt parameters according to the patient's position or changes in intracranial pressure, achieving precise and personalized hydrocephalus treatment.

[0004] Currently available automatic adjustable hydrocephalus shunt devices consist of a shunt catheter and a one-way valve. During use, the preset catheter path and valve opening angle facilitate the flow of cerebrospinal fluid in a designated direction. To improve the stability of the shunt path, existing technologies reinforce the position through a fixed anchor point and a fitting structure to the outer wall of the catheter. Furthermore, to accommodate differences in cerebrospinal fluid volume among patients, existing technologies employ adjustable mechanical valves to adjust the flow rate of the hydrocephalus shunt. However, this method is difficult to adjust in real time based on intracranial pressure, and the lack of smoothness during adjustment affects the continuity of cerebrospinal fluid drainage, thus reducing the reliability of the device.

[0011] Preferably, the adjustment mechanism further includes a guide rod, which is fixedly connected to the top of the movable cover, and the outer side of the guide rod is slidably connected to the outer cover.

[0012] Preferably, the high-voltage assembly includes a reset spring, and multiple reset springs are fixedly connected to the inside left side of the movable cover. A piston is fixedly connected to the outside of the reset spring, and a U-shaped rod is fixedly connected to the outside of the piston. The inside of the U-shaped rod is slidably connected to the hollow plate.

[0013] Preferably, the preset component includes a reserved slot, two of which are respectively disposed on the front and rear sides of the hollow plate.

[0017] This invention provides an automatic adjustment device for hydrocephalus shunts. It has the following beneficial effects:

[0018] 1. This invention uses a base to attach the outer cover to the affected area. Cerebrospinal fluid enters the device and is discharged into the abdominal cavity through an external pipe connected to the water outlet cover. During operation, the patient's movement causes changes in intracranial pressure, and the flow rate drives the spring coil, causing the movable cover to move. The holes are exposed at different lengths depending on the moving distance, and the drainage volume is adjusted according to the pressure. Before installation, the rotating rod drives the adjusting block through the gear set to adjust the moving cover distance to preset the drainage effect, so that the drainage volume can be adjusted in real time according to intracranial pressure, thereby improving the reliability of the device.

[0019] 2. This invention utilizes the flow of cerebrospinal fluid due to intracranial pressure, allowing small impurities to pass directly into the abdominal cavity, while large impurities are intercepted by the filter. The flow of cerebrospinal fluid drives the paddle blade, which in turn drives the scraper to rotate along the crushing plate, breaking the impurities down to the size allowed by the filter, preventing blockage or affecting the operation of the device, thereby improving the practicality of the device.

[0020] 3. This invention uses the flow of cerebrospinal fluid to drive the second paddle, causing the water outlet cover to rotate. This, in turn, pushes the crushing rod and the rotating ring to rotate along the mounting cover, preventing or destroying the growth of muscle tissue on the base and outer cover surface. This addresses postoperative tissue fibrosis and prevents duct blockage, eliminating the need for repeated maintenance of the device and thus improving its convenience. Attached Figure Description

[0030] The technical solutions in 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.

[0031] Reference Figure 1 , Figure 4 and Figure 6 This invention provides an automatic regulating hydrocephalus shunt device, including a base 1, an outer cover 5 on the top of the base 1, cerebrospinal fluid being fed into the outer cover 5 through an external inlet pipe, an adjustment mechanism 2 on the left side inside the outer cover 5 for draining the saturated fluid, a filter mechanism 3 on the right side inside the outer cover 5 for treating impurities, and a protective mechanism 4 on the outside of the outer cover 5 for preventing biocompatibility adhesion of the device.

[0032] The adjusting mechanism 2 includes a spring coil 212, which is fixedly connected to the inside right side of the base 1. A movable cover 21 is fixedly connected to the left side of the spring coil 212. As the cerebrospinal fluid flows due to pressure, it pushes the spring coil 212 to extend and retract, thereby moving the movable cover 21. A hollow plate 22 is fixedly connected to the inside left side of the outer cover 5. The hollow plate 22 not only serves to fix the cover but also limits the range of movement of the movable cover 21 to prevent it from falling off. The movable cover 21 passes through the outside of the hollow plate 22. A rotating rod 23 is rotatably connected to the middle of the inner side of the hollow plate 22. A bevel gear 24 is fixedly connected to both the front and rear sides of the rotating rod 23. The rotating rod 23 and the bevel gear 24 can rotate along the inner side of the hollow plate 22. A bevel gear 25 is rotatably connected to both the front and rear sides of the right end of the hollow plate 22. 25 meshes with bevel gear 24. A threaded rod 26 is fixedly connected to the right side of bevel gear 25. The outer side of the threaded rod 26 passes through the hollow plate 22 and is threadedly connected to an adjusting block 27. Rotating bevel gear 24 will drive bevel gear 25 and threaded rod 26 to rotate. The threaded rod 26 pushes the adjusting block 27 to move. The adjusting block 27 is slidably connected to the hollow plate 22. A water outlet cover 210 is rotatably connected to the left side of the moving cover 21. An external water outlet pipe is rotatably connected to the outer side of the water outlet cover 210. The rotatable connection can prevent the water outlet pipe from rotating itself. At the same time, the large space inside the water outlet cover 210 can not only pre-store cerebrospinal fluid but also provide space for the movement of the moving cover 21. A high-pressure component 28 is provided on the left side of the moving cover 21, and a preset component 29 is provided on the outer side of the hollow plate 22.

[0033] Specifically, the outer cover 5 is fixed to the affected area with the help of the base 1, allowing cerebrospinal fluid to enter the device. The cerebrospinal fluid is then drained into the patient's abdominal cavity for absorption through the external water outlet pipe that is rotatably connected to the water outlet cover 210. During operation, the patient's movements will cause different intracranial pressures, which in turn affect the flow rate of cerebrospinal fluid drainage. Different flow rates will push the spring coil 212 to stretch, causing the movable cover 21 to move. The front and rear holes of the movable cover 21 will be exposed at different lengths due to the movement distance, thereby adjusting the drainage volume in a timely and stable manner according to the pressure. In addition, the drainage effect can be preset before the device is installed. By rotating the rod 23 and the bevel gear 1 24, the bevel gear 25 is driven to rotate, which in turn drives the threaded rod 26 to rotate, causing the adjusting block 27 to extend from the hollow plate 22, adjusting the movement distance of the movable cover 21 to achieve drainage control.

[0034] Reference Figure 4 , Figure 6 and Figure 7The filter mechanism 3 includes a connecting ring 31, which is fixedly connected to the inside right side of the movable cover 21. A filter screen 32 is fixedly connected to the middle of the inner side of the connecting ring 31. The filter screen 32 allows impurities small enough not to affect the operation of the device to flow through, and intercepts large impurities. A paddle 33 is rotatably connected to the left side of the filter screen 32. A scraper 34 is fixedly connected to the right side of the paddle 33 through the filter screen 32. The paddle 33 will rotate with the flow of cerebrospinal fluid and drive the scraper 34 on it to rotate together. A crushing plate 35 is fixedly connected to the right side of the filter screen 32. The scraper 34 will crush large impurities into small impurities along the rotation of the crushing plate 35. A crushing component 36 is provided inside the right side of the connecting ring 31. A positioning component 37 is provided at the bottom of the base 1.

[0035] Specifically, when cerebrospinal fluid flows due to intracranial pressure, small impurities that do not affect the operation of the device will pass directly through the device and eventually be sent into the abdominal cavity for absorption, while large impurities will be intercepted on the surface by the filter screen 32. The flow of cerebrospinal fluid will drive the paddle 33 to rotate, and the paddle 33 will drive the scraper 34 to rotate along the crushing plate 35 to break up impurities of all sizes until the size of the impurities reaches the standard that the filter screen 32 can pass through, thus preventing large impurities from clogging the device or affecting its normal operation.

[0036] Reference Figure 2 , Figure 3 and Figure 8 The protective mechanism 4 includes a second blade 41, which is fixedly connected to the inside left side of the water outlet cover 210. A rotating cover 42 is fixedly connected to the right side of the water outlet cover 210. When the water outlet cover 210 rotates, it will drive the rotating cover 42 to rotate. Multiple breaking rods 43 are fixedly connected to the right side of the rotating cover 42. A rotating ring 45 is fixedly connected to the right side of the breaking rods 43. An installation cover 44 is rotatably connected to the outside of the rotating ring 45. When the rotating cover 42 rotates, the breaking rods 43 will rotate together with the rotating ring 45 along the installation cover 44. The installation cover 44 is fixedly connected to the outside right side of the base 1. The bottom of the installation cover 44 is fixedly connected to the base 1.

[0037] Specifically, the flow of cerebrospinal fluid will cause the second blade 41 to rotate, which in turn causes the water outlet cover 210 to rotate. As the water outlet cover 210 rotates, multiple breaking rods 43 will rotate along the mounting cover 44 with the rotating ring 45. The rotation of the breaking rods 43 can prevent or destroy the growth of muscle tissue on the surface of the base 1 and the outer cover 5, thereby addressing postoperative tissue fibrosis and preventing catheter blockage.

[0038] Reference Figure 1 , Figure 2 and Figure 6The adjustment mechanism 2 also includes a water inlet cover 211, which is located on the right side of the movable cover 21. The outer side of the water inlet cover 211 is fixedly connected to the outer cover 5. The water inlet pipe connected to the outside of the water inlet cover 211 facilitates the receipt of cerebrospinal fluid. The adjustment mechanism 2 also includes a guide rod 213, which is fixedly connected to the top of the movable cover 21. The outer side of the guide rod 213 is slidably connected to the outer cover 5. The sliding of the guide rod 213 can improve the stability of the movable cover 21 when it moves.

[0039] Specifically, the water inlet cover 211 can be connected to an external water inlet pipe, which is connected to the brain to receive cerebrospinal fluid, which is then sent into the outer cover 5 through the water inlet cover 211. The sliding and guiding of the guide rod 213 with the outer cover 5 can improve the stability of the moving cover 21 during movement.

[0040] Reference Figure 2 , Figure 4 and Figure 5 The high-pressure component 28 includes a return spring 282. Multiple return springs 282 are fixedly connected to the inside left side of the movable cover 21. A piston 281 is fixedly connected to the outside of the return spring 282. The return spring 282 can reset the piston 281. A U-shaped rod 283 is fixedly connected to the outside of the piston 281. The inside of the U-shaped rod 283 is slidably connected to the hollow plate 22. When the movable cover 21 moves, it restricts the movement of the U-shaped rod 283. The restricted U-shaped rod 283 will prevent the piston 281 from moving and will open the piston door 281 as the movable cover 21 continues to move. The preset component 29 includes a reserved slot 291. Two reserved slots 291 are respectively set on the front and rear sides of the outside of the hollow plate 22. A knob 292 is rotatably connected to the inside of the reserved slot 291. The knob 292 will rotate along the reserved slot 291. The outside of the knob 292 passes through the hollow plate 22 and is fixedly connected to the rotating rod 23. Rotating the knob 292 will drive the rotating rod 23 to rotate.

[0041] Specifically, when intracranial pressure is high and needs to be drained immediately, the thrust of intracranial pressure will cause the movable cover 21 to move to the limit of the spring coil 212. At this time, during the movement, the return spring 282 and the piston 281 will also move to maintain the seal of the movable cover 21. As the movable cover 21 moves to the limit, the position of the piston 281 will be restricted by the hollow plate 22, so that the return spring 282 pulls out the piston 281 to fully open the left side of the movable cover 21, so as to drain the cerebrospinal fluid when the intracranial pressure is high on a large scale. By rotating the knob 292 in the reserved slot 291, it is easy to drive the rotating rod 23 to rotate simultaneously while the knob 292 is rotating.

[0042] Reference Figure 1 , Figure 2 and Figure 7The crushing component 36 includes a second connecting ring 361, which is fixedly connected to the inside right side of the first connecting ring 31. The inner side of the second connecting ring 361 has a threaded groove 362, which forces the impurities in the cerebrospinal fluid to rotate, thereby improving the subsequent crushing effect, and also has a certain crushing ability itself. The positioning component 37 includes a barb 371, which is fixedly connected to the bottom of the base 1 around the perimeter. The barb 371 hooks the muscle tissue for fixation, and the barb 371 will connect with the muscle tissue during long-term use to improve the fixation effect. The outer side of the base 1 has multiple suture holes 372, which facilitate the device to be fixed by sewing surgical sutures during the initial installation. The protective mechanism 4 also includes a bracket 46, which is fixedly connected to the outer side of the water outlet cover 210. The outer side of the bracket 46 is fixedly connected to the rotating cover 42, and the bracket 46 can provide a fixing effect for the rotating cover 42.

[0043] Specifically, by connecting the second ring 361 to the inner threaded groove 362, when cerebrospinal fluid passes through the threaded groove 362, it will be forced to make a spiral motion along the threaded groove 362 to reduce the impact and adhesion on the filter screen 32, and disturb the water flow to disperse viscous impurities. The device can be fixed by sutures through the suture hole 372 during installation. At the same time, the barb 371 can be hooked on the affected area during installation. The barb 371 has a rounded, non-sharp design to prevent cutting muscle fibers and causing the device to shift. The bracket 46 can ensure the firmness of the fixation between the rotating cover 42 and the water outlet cover 210. At the same time, the rotation of the bracket 46 can further prevent the muscle from growing together with the device.

[0044] Working principle: The outer cover 5 is installed on the affected area via the base 1 to receive cerebrospinal fluid into the device. The cerebrospinal fluid is discharged into the patient's abdominal cavity for absorption through an external water outlet pipe that is rotatably connected to the water outlet cover 210. During device operation, the intracranial pressure will vary with the patient's movement, and the flow rate of cerebrospinal fluid discharged will also vary with the pressure. According to the different flow rates, the spring coil 212 will be stretched to push the movable cover 21 to move. After the movable cover 21 moves, the holes on its front and rear sides will be exposed to different lengths due to the movement distance. This allows for timely and stable adjustment of the drainage volume according to the pressure. Furthermore, the drainage effect of the device can be preset according to the needs before installation. Specifically, the rotating rod 23 and the bevel gear 1 24 drive the bevel gear 25 that meshes with it to rotate. As the bevel gear 25 and its upper threaded rod 26 rotate, the adjusting block 27 extends out from the hollow plate 22 to adjust the movement distance of the movable cover 21, thereby controlling the device.

[0045] Furthermore, when the cerebrospinal fluid flows due to intracranial pressure, small impurities that do not affect the operation of the device will pass directly through and eventually be sent into the abdominal cavity for absorption, while large impurities will be intercepted on the surface by the filter 32. The flow of cerebrospinal fluid will drive the paddle 33 to rotate, and as the paddle 33 rotates, it will drive the scraper 34 to rotate along the crushing plate 35 to break up impurities of all sizes until they are broken down to the size that the filter 32 can allow to pass through, thereby preventing large impurities from clogging the device or affecting the normal operation of the device.

[0046] Finally, the flow of cerebrospinal fluid will also drive the second blade 41 to rotate. The rotation of the second blade 41 can drive the water outlet cover 210 to rotate, and as the water outlet cover 210 rotates, it pushes multiple breaking rods 43, causing them and the rotating ring 45 to rotate along the mounting cover 44. The rotation of the breaking rods 43 will prevent or destroy muscle tissue from growing on the surface of the base 1 and the outer cover 5, in order to deal with postoperative tissue fibrosis and prevent catheter blockage.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
