[0002] Hydrocephalus is a common neurological disease that can be caused by a variety of reasons, such as obstruction of the cerebrospinal fluid circulation pathway, excessive secretion of cerebrospinal fluid or absorption disorders. When hydrocephalus occurs, the ventricular system will expand, leading to increased intracranial pressure. Increased intracranial pressure can cause a series of symptoms such as headache, vomiting, visual impairment, and impaired consciousness. In severe cases, it can be life-threatening.

[0019] The present invention has the following beneficial effects:

[0020] 1. The present invention first places the main body and the upper half of the tube on both sides of the catheter respectively, then presses the main body and the upper half of the tube so that the two clamping blocks on the upper half of the tube are inserted into the inside of the clamping groove so that the main body and the upper half of the tube form a circular tube on the outer surface of the catheter, then the main body and the upper half of the tube that form the circular tube can be connected to the handle through the threaded groove opened on the surface for convenient puncture, then when the main body and the upper half of the tube are combined into a circular tube, the catheter will be tightly clamped, then the medical staff will hold the circular tube formed by the combination of the main body and the upper half of the tube to perform puncture and drainage on the catheter, then after the catheter is inserted into the patient's body in place, the handles screwed on the outer surfaces of the main body and the upper half of the tube are loosened, at this time, the spring blocks in the main body and the upper half of the tube will push the main body and the upper half of the tube to separate them under the elastic force of the reset spring, at this time, the catheter will be withdrawn between the main body and the upper half of the tube, and the installation operation of the guide tube is completed, so that the guide tube can be accurately transported to the predetermined position when inserted into the patient's body for diversion, and the deviation or bending of the catheter during insertion can be reduced by covering the main body and the upper half of the tube, thereby improving the accuracy of the installation of the guide tube and improving the drainage effect.

[0021] 2. According to the present invention, when the main body and the upper half tube are combined into a circular pipe, the combination of the main body and the upper half tube will squeeze the elastic semicircular plate. After being squeezed, the elastic semicircular plate will push the rotating plate to rotate at its bottom through the rotating frame. After being pushed, the rotating plate will push the rotating frame and compress the reset spring to make it slide inside the sliding groove. When the rotation of the rotating frame pushes the rotating plate to rotate at the bottom of the rotating frame, it will drive the elastic semicircular plate to slide downward synchronously. When the elastic semicircular plate slides downward, it will drive the long rod 2 and squeeze the side wall of the inclined block through the right-angle blocks at both ends of the long rod 2. After being squeezed, the side wall of the inclined block will slide relatively and squeeze the elastic plate. After being squeezed, the elastic plate will produce a bulging deformation in the middle part, which will squeeze the side wall of the guide tube. When the two elastic plates are deformed and squeeze the guide tube, the sliding of the guide tube in the main body and the upper half tube during insertion can be reduced, and the discomfort caused to the patient due to the sliding of the catheter when the guide tube is inserted into the patient's ventricle can be reduced, thereby improving the comfort of the patient during catheter insertion.

[0022] 3. According to the present invention, when the rotating frame rotates downward, it will squeeze the rotating plate and drive the spring block to slide backward. When the rotating plate slides backward, it will drive the C-shaped frame to slide backward through the connecting plate. When the C-shaped frame slides backward, it will drive the elastic semicircular plate on the left to slide backward on the surface of the long rod. At this time, the distance between the two elastic semicircular plates will become longer and slide on the surface of the catheter. At the same time, when the rotating plate drives the elastic semicircular plate to slide downward, the downward rotation of the elastic semicircular plate will make the bottom of the middle plate contact with the inner wall of the circular pipe composed of the main body and the upper half pipe. Then, when the rotating frame continues to rotate downward, the middle plate will push the movable plate to slide on the surface of the T-bar under the squeezing of the inner wall of the circular pipe. When the middle plate pushes the movable plate to slide, it will drive the long rod 2 to slide synchronously inside the sliding frame. The sliding frame is elastic. When the movable plate pushes the long rod 2 to slide, it will drive the two ends of the elastic semicircular plate to slide to both sides. Then, when the main body and the upper half pipe are separated, the rotating frame and the rotating plate will be reset under the elastic force of the reset spring on the spring block. When the rotating frame and the rotating plate are reset, the two elastic semicircular plates will approach each other according to the above principle. When the two elastic semicircular plates are close to each other, they will slide on the surface of the guide tube and can smooth it to a certain extent on the surface of the guide tube when sliding. The sliding of the two elastic semicircular plates can reduce the situation that the guide tube is locally subjected to excessive pressure after being squeezed by the elastic plate, resulting in local bending of the guide tube. By reducing the local pressure and bending of the guide tube, the drainage of the guide tube can be kept unobstructed, thereby improving the drainage speed.

[0023] 4. In the present invention, when the movement of the middle plate pushes the movable plate to move on the surface of the T-bar, it can drive the synchronous movement of the second long bar. When the second long bar moves, it will drive the second connecting plate to slide synchronously. When the second connecting plate is driven by the second long bar to slide, it will drive the pushing block to slide inside the elastic semicircular plate through the auxiliary rod. When the pushing block slides, it will squeeze the semicircular protrusions on the side walls of the second semicircular plate. After the semicircular plate is squeezed by the pushing block, it will drive the right-angle ring to rotate inside the elastic semicircular plate. When the second semicircular plate drives the right-angle ring to rotate in the elastic semicircular plate, the inclined ring inside the elastic semicircular plate will squeeze the inclined groove on the right-angle ring and make the right-angle ring slide on the side wall of the second semicircular plate. When the right-angle ring slides, it will Several balls on the semicircular plate 2 are disengaged. At the same time, when the semicircular plate 2 rotates, the semicircular ring is squeezed by the inner wall of the elastic semicircular plate and disengaged from the side wall of the ball. Then, when the semicircular plate 2 rotates, it drives multiple balls to extend out of the side wall of the elastic semicircular plate and contact with the outer surface of the guide tube. When the side wall of the elastic semicircular plate at the extension point of multiple balls contacts with the surface of the guide tube, the sliding friction of the elastic semicircular plate when sliding on the surface of the guide tube can be converted into rolling friction, thereby reducing the friction between the elastic semicircular plate and the guide tube when sliding, reducing the situation where the elastic semicircular plate slides on the surface of the guide tube due to excessive friction, causing the guide tube to be stretched on the surface of the guide tube and causing deformation, thereby improving the safety and reliability during the insertion and drainage process.

When the rotation of the rotating frame 303 drives the rotating plate 302 to rotate at the bottom of the rotating frame 303, it will drive the elastic semicircular plate 401 to slide downward synchronously.

[0044] The top of the connecting block 304 is provided with an auxiliary mechanism 4, which includes two elastic semicircular plates 401 arranged and connected to the top of the connecting block 304. The elastic semicircular plate 401 on the right is fixedly connected to the top of the connecting block 304. The left side of the elastic semicircular plate 401 on the right is fixedly connected with a long rod 403, which penetrates the outer wall of the elastic semicircular plate 401 on the left and extends to the outside. The outer surface of the elastic semicircular plate 401 is fixedly connected with two sliding frames 402. The side wall of the elastic semicircular plate 401 on the left is fixedly connected to the outer wall of the elastic semicircular plate 401 on the left. A tension spring is connected, and one end of the tension spring away from the elastic semicircular plate 401 is fixedly connected to the side wall of the long rod 403. The side wall of the left elastic semicircular plate 401 is fixedly connected to a C-shaped frame 404. When the rotating frame 303 rotates downward, it squeezes the rotating plate 302 to drive the spring block 301 to slide backward. When the rotating plate 302 slides backward, it drives the C-shaped frame 404 to slide backward through the connecting plate 405. When the C-shaped frame 404 slides backward, it drives the elastic semicircular plate 401 on the left to slide backward on the surface of the long rod 403.

[0045] Two connecting plates 405 are rotatably connected to the central axis of the C-shaped frame 404, and one end of the two connecting plates 405 away from the C-shaped frame 404 is rotatably connected to the side wall of the rotating plate 302. Four tilting rings 406 are fixedly connected to the top inner wall of the elastic semicircular plate 401. The four tilting rings 406 are symmetrically distributed in pairs, and the two groups of tilting rings 406 are symmetrically distributed with the long rod 403 as the center. The side walls of the tilting rings 406 are provided with arc grooves, and the elastic semicircular plate 401 is hollow. Since the elastic semicircular plate 401 and the sliding frame 402 are elastic, when the movable plate 502 pushes the long rod 501 to slide, it will drive the two ends of the elastic semicircular plate 401 to slide to both sides.

[0046] The side wall of the elastic semicircular plate 401 is provided with a sliding mechanism 5, and the sliding mechanism 5 includes a long rod 2 501 slidably connected to the inside of the two sliding frames 402, and the left and right sides of the long rod 2 501 are fixedly connected with right-angle blocks, and the outer surface of the long rod 2 501 is fixedly connected with a movable plate 502.

After that, when the main body 1 and the upper half tube 101 are combined into a circular pipe, the catheter will be tightly clamped, and then the medical staff will hold the circular pipe formed by the combination of the main body 1 and the upper half tube 101 to puncture and drain the catheter, and then After the catheter is inserted into the patient's body and in place, the handles screwed on the outer surfaces of the main body 1 and the upper half tube 101 are loosened. At this time, the spring block 301 in the main body 1 and the upper half tube 101 will push the main body 1 and the upper half tube 101 to separate them under the elastic force of the reset spring. At this time, the catheter will withdraw between the main body 1 and the upper half tube 101, completing the installation operation of the guide tube, so that the guide tube can be accurately delivered to the predetermined position when inserted into the patient's body for diversion.

After being pushed, the rotating plate 302 will push the rotating frame 303 and compress the reset spring to make it slide inside the sliding groove 104. When the rotation of the rotating frame 303 pushes the rotating plate 302 to rotate at the bottom of the rotating frame 303, it will drive the elastic semicircular plate 401 to slide downward synchronously. When the elastic semicircular plate 401 slides downward, it will drive the long rod 2 501 and the right-angle blocks at both ends of the long rod 501 squeeze the side wall of the inclined block 201. After being squeezed, the side wall of the inclined block 201 will slide relatively and squeeze the elastic plate 202. After being squeezed, the elastic plate 202 will produce a bulge in the middle to squeeze the side wall of the guide tube. When the two elastic plates 202 are deformed and squeeze the guide tube, the sliding of the guide tube in the main body 1 and the upper half tube 101 during insertion can be reduced, and the discomfort caused to the patient due to the sliding of the catheter when the guide tube is inserted into the patient's ventricle can be reduced, thereby improving the patient's comfort during catheter insertion.

[0052] When the rotating frame 303 rotates downward, it will squeeze the rotating plate 302 and drive the spring block 301 to slide backward. When the rotating plate 302 slides backward, it will drive the C-shaped frame 404 to slide backward through the connecting plate 405. When the C-shaped frame 404 slides backward, it will drive the elastic semicircular plate 401 on the left to slide backward on the surface of the long rod 403. At this time, the distance between the two elastic semicircular plates 401 will become longer and slide on the surface of the catheter. At the same time, when the rotating plate 302 drives the elastic semicircular plate 401 to slide downward, the downward rotation of the elastic semicircular plate 401 will make the bottom of the middle plate 503 contact the inner wall of the circular pipe composed of the main body 1 and the upper half pipe 101. Then, when the rotating frame 303 continues to rotate downward, the middle plate 503 will push the movable plate 502 to slide on the surface of the T-shaped rod 504 under the squeezing of the inner wall of the circular pipe. When the middle plate 503 pushes the movable plate 502 to slide, it will drive the long rod 2 501 to slide synchronously inside the sliding frame 402 , since the elastic semicircular plate 401 and the sliding frame 402 are elastic, when the movable plate 502 pushes the long rod 2 501 to slide, it will drive the two ends of the elastic semicircular plate 401 to slide to both sides, and then when the main body 1 and the upper half pipe 101 are separated, the rotating frame 303 and the rotating plate 302 will be reset under the elastic force of the reset spring on the spring block 301. When the rotating frame 303 and the rotating plate 302 are reset, the two elastic semicircular plates 401 will approach each other according to the above principle. When the two elastic semicircular plates 401 are close to each other, they will slide on the surface of the guide tube and can play a certain smoothing effect on the surface of the guide tube when sliding. The sliding of the two elastic semicircular plates 401 can reduce the situation that the guide tube is locally subjected to excessive pressure after being squeezed by the elastic plate 202, resulting in local bending of the guide tube. By reducing the local pressure and bending of the guide tube, the patency of the guide tube drainage can be maintained, thereby improving the drainage speed.

[0053] When the movement of the middle plate 503 pushes the movable plate 502 to move on the surface of the T-bar 504, it can drive the long rod 2 501 to move synchronously. When the long rod 2 501 moves, it will drive the connecting plate 2 605 to slide synchronously. When the connecting plate 2 605 is driven by the long rod 2 501 to slide, it will drive the pushing block 604 to slide inside the elastic semicircular plate 401 through the auxiliary rod. When the pushing block 604 slides, it will squeeze the semicircular protrusions on the side walls of the semicircular plate 2 601. After being squeezed by the pushing block 604, the semicircular plate 2 601 will drive the right-angle ring 602 to rotate inside the elastic semicircular plate 401. When the semicircular plate 2 601 drives the right-angle ring 602 to rotate in the elastic semicircular plate 401, the inclined ring 406 inside the elastic semicircular plate 401 will squeeze the inclined groove on the right-angle ring 602 and make the right-angle ring 602 rotate on the semicircular plate 2 601. The side wall slides, and when the right-angle ring 602 slides, it will disengage from several balls on the semicircular plate 601. At the same time, when the semicircular plate 601 rotates, the semicircular ring 603 will be squeezed by the inner wall of the elastic semicircular plate 401 and disengaged from the side wall of the ball. Then, when the semicircular plate 601 rotates, it will drive multiple balls to extend out of the side wall of the elastic semicircular plate 401 and contact the outer surface of the guide tube. When multiple balls extend out of the side wall of the elastic semicircular plate 401 and contact the surface of the guide tube, the sliding friction of the elastic semicircular plate 401 when sliding on the surface of the guide tube can be converted into rolling friction, thereby reducing the friction between the elastic semicircular plate 401 and the guide tube when sliding, reducing the deformation of the guide tube caused by the stretching of the guide tube surface due to excessive friction when the elastic semicircular plate 401 slides on the surface of the guide tube, thereby improving the safety and reliability during the insertion and drainage process.
