In the process of the drainage tube draining the liquid in the patient's brain, the pushing plate of the pushing mechanism intermittently squeezes the drainage tube under the limiting action of the limiting mechanism, and the pushing plate will squeeze the drainage tube only when the movement direction of the pushing plate is the same as the flow direction of the liquid drained in the drainage tube, so that the pushing plate squeezes and pushes the blockage adhered to the inner wall of the drainage tube along the drainage direction, reducing the probability of the drainage tube being blocked, preventing the drainage tube from being blocked, resulting in a decrease in the flow speed of the liquid inside the drainage tube, and increasing the intracranial pressure of the patient, thereby ensuring the smoothness of the drainage and providing good protection for the patient.

Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a ventricular drainage device. Background Art

[0002] Ventricular drainage is an important neurosurgical procedure used to relieve increased intracranial pressure and drain cerebrospinal fluid. Specifically, after ventricle puncture through skull perforation or during craniotomy, the front end of a drainage tube with several side holes is placed in the ventricle, and the end is connected to a ventricular drainage bottle to drain the cerebrospinal fluid out of the body. Its advantages mainly include the following aspects: Relieve increased intracranial pressure: Ventricular drainage can quickly reduce excessive intracranial pressure, which is of great significance for preventing brain herniation and protecting brain tissue from damage; by draining excess cerebrospinal fluid, the patient's symptoms can be effectively relieved.

[0003] The current nursing plan for drainage bags of ventricular drainage patients is to fix the drainage bag on a hanging rod and set the vertical distance between the drainage bag and the patient's brain to drain the intraventricular fluid. However, during postoperative drainage, only one hanging height is maintained, and the hanging height of the drainage bag cannot be adjusted in real time with the changes in the patient's intracranial pressure, resulting in greater risks. In addition, when draining the ventricular fluid, the ventricular fluid will contain blood clots formed by postoperative bleeding and protein deposits in cerebrospinal fluid. These soft objects will block the drainage tube. If the blocked drainage tube is not cleared in time, the patient's intracranial pressure will increase, causing unnecessary consequences. Based on this, a ventricular drainage device is proposed. Summary of the invention

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention uses a pushing mechanism and a limiting mechanism in coordination. During the process of the drainage tube draining the fluid from the patient's brain, the pushing plate of the pushing mechanism intermittently squeezes the drainage tube under the limiting action of the limiting mechanism, and the pushing plate will squeeze the drainage tube only when the movement direction of the pushing plate is the same as the flow direction of the fluid drained in the drainage tube, so that the pushing plate squeezes and pushes the blockage adhered to the inner wall of the drainage tube along the drainage direction, thereby reducing the probability of drainage tube blockage, preventing the drainage tube from being blocked, resulting in a decrease in the flow rate of the fluid inside the drainage tube, and increasing the intracranial pressure of the patient, thereby ensuring the smoothness of the drainage and providing good protection for the patient.

[0023] 2. The present invention uses a servo motor, a controller, a laser tracker, an intracranial pressure monitor, a turntable and a traction rope in coordination. The servo motor controls the hanging height of the drainage bag so that the drainage point on the drainage bag maintains a required height difference with the drainage point on the patient's head. Manual adjustment by the nursing staff is unnecessary, thereby reducing the workload of the nursing staff. In addition, the laser tracker tracks the vertical distance between the drainage point on the patient's head and the drainage point on the drainage bag. When the height of the patient's head changes, the drainage bag is controlled by the servo motor so that the drainage point on the patient's head and the drainage point on the drainage bag still maintain the original vertical distance in real time, thereby ensuring accurate treatment and facilitating the patient's recovery. In addition, the vertical distance between the drainage point of the drainage bag and the drainage point of the patient can be set according to the different intracranial pressures of different patients to accommodate patients with different symptoms.

[0024] 3. The present invention uses a pushing mechanism and a knocking mechanism in coordination. During the process of the pushing mechanism intermittently squeezing the drainage tube to squeeze and push the blockage in the drainage tube, the knocking mechanism will knock on the drainage tube in the forward direction of the pushing plate squeezing the drainage tube, so that the drainage tube vibrates, and the blockage adhered to the inner wall of the drainage tube can be separated from the drainage tube under the vibration of the drainage tube, and then cooperate with the squeezing and pushing of the pushing mechanism to enable the blockage to be quickly discharged through the drainage tube, and the knocking of the knocking mechanism causes the drainage tube to vibrate, thereby reducing the probability of blood clots formed after intracranial surgery and protein deposits in cerebrospinal fluid adhering to the inner wall of the drainage tube, thereby further reducing the probability of drainage tube blockage and ensuring the smoothness of drainage.

[0025] 4. The present invention uses a pushing mechanism and a kneading mechanism in coordination. When the pushing plate of the pushing mechanism squeezes the drainage tube, the pushing plate contacts the upper kneading plate and the lower kneading plate of the kneading mechanism. The back-and-forth movement of the upper kneading plate and the lower kneading plate cooperates with the squeezing and pushing of the pushing plate, so that the blood clots formed after surgery and the protein deposits in the cerebrospinal fluid adhering to the inner wall of the drainage tube can be completely separated from the inner wall of the drainage tube. In addition, during the drainage process, the upper kneading plate and the lower kneading plate knead the drainage tube, so that the blood clots formed after surgery and the protein deposits in the cerebrospinal fluid in the drainage tube not only move in the drainage direction, but also move perpendicular to the drainage direction, which can destroy the blood clots that enter the drainage tube. The inherent forms of blood clots and protein deposits in the cerebrospinal fluid further reduce the probability of blood clots formed after surgery and protein deposits in the cerebrospinal fluid adhering to the inner wall of the drainage tube. In addition, the lower kneading plate and the upper kneading plate made of thermal insulation rubber can insulate the drainage tube to a certain extent, slowing down the cooling rate of the brain fluid drained by the drainage tube, thereby slowing down the coagulation rate of blood clots and protein deposits, and making the fluid drained in the drainage tube have good fluidity, thereby further reducing the probability of blood clots formed after surgery and protein deposits in the cerebrospinal fluid adhering to the inner wall of the drainage tube, ensuring the smooth drainage of the drainage tube, and thus reducing the probability of complications caused by increased intracranial pressure.

DETAILED DESCRIPTION

[0044] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0045] Example 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.14 and Fig.15As shown, a ventricular drainage device includes a controller 1, a drainage tube 8 and a drainage bag 7. The drainage tube 8 is in the form of a medical rubber hose. The controller 1 is connected to a laser tracker 2 through a control line. The laser tracker 2 measures the vertical height difference between the drainage point on the drainage bag 7 and the drainage point on the patient's head, and inputs it into the controller 1. The controller 1 calculates the intracranial pressure and the vertical distance between the drainage bag 7 and the drainage point. When it deviates from the preset value, the controller 1 controls the servo motor 4 to rotate, and drives the traction rope 6 to move up and down through the turntable 5, so that the drainage point on the drainage bag 7 and the drainage point on the patient's head are The height difference between them matches the intracranial pressure, so that the drainage effect of the drainage bag 7 is in the best state. The controller 1 is connected to the intracranial pressure monitor 3 through the control line. The intracranial pressure monitor 3 can monitor the intracranial pressure of the patient. The vertical distance between the drainage point on the drainage bag 7 and the patient's drainage point is set according to the intracranial pressure to ensure accurate drainage. The controller 1 is connected to the servo motor 4 through the control line. The controller 1, the laser tracker 2, the intracranial pressure monitor 3 and the servo motor 4 are installed on the wall through the installation platform (the installation platform can be an object such as a flat plate, and the installation platform is a prior art, not shown in the figure The output end of the servo motor 4 is fixedly connected to a turntable 5, the outer surface of the turntable 5 is wound with a traction rope 6, the free end of the traction rope 6 is fixedly connected to a drainage bag 7, a drainage tube 8 is fixedly connected to the top of the drainage bag 7, the free end of the drainage tube 8 is fixedly connected to a drainage head 9, an intracranial pressure sampling line 10 is installed in the drainage head 9, the intracranial pressure sampling line 10 is connected to the controller 1, the intracranial pressure sampling line 10 is implanted in the patient's ventricle to measure the intracranial pressure, and the other end is connected to the intracranial pressure monitor 3, and the intracranial pressure is calculated by the intracranial pressure monitor 3, and It is displayed for medical staff to observe, and the measured intracranial pressure is transmitted to the inside of the controller 1 as a parameter for the controller 1 to control the movement of the servo motor 4. After the patient's surgery, the drainage head 9 of the drainage tube 8 is implanted into the drainage point in the patient's ventricle. The other end of the drainage tube 8 is connected to the drainage bag 7, and the drainage bag 7 is lower than the patient's drainage point. In this way, the liquid will be drained into the drainage bag 7 under the action of gravity. In order to prevent excessive or insufficient drainage, it is necessary to ensure that the height difference between the drainage bag 7 and the patient's drainage point is a certain value, and it is set to different values ​​according to the intracranial pressure.

[0046] When in use, first insert the drainage head 9 into the drainage point of the patient's head and fix it firmly to ensure the sealing. At this time, the relationship between the intracranial pressure and the drainage height can be set to ensure that the drainage height and the pressure difference are matched at any time. For example, when caring for the patient's head, lift the patient's head. At this time, the position of the drainage point of the patient's head changes. The laser tracker 2 measures the change in the vertical distance between the drainage point of the patient's head and the drainage point on the drainage bag 7. At this time, the controller 1 controls the servo motor 4 to rotate, and the position of the drainage bag 7 is raised by winding and releasing the traction rope 6 of the turntable 5, so that the drainage point of the patient's head and the drainage point on the drainage bag 7 are aligned. The vertical height is kept unchanged to the original distance. When the intracranial pressure of the patient increases, the controller 1 controls the servo motor 4 to rotate, and the position of the drainage bag 7 is lowered by winding and releasing the traction rope 6 of the turntable 5, thereby increasing the distance between the drainage point on the patient's head and the drainage point on the drainage bag 7, accelerating the liquid drainage speed in the drainage tube 8, and quickly reducing the patient's intracranial pressure, so that the drainage effect is in the best state. Therefore, the height difference between the patient's drainage point and the drainage point on the drainage bag 7 is matched with the intracranial pressure according to the set relationship. The whole process is automatic operation, which saves the workload of nursing staff and helps patients with accurate drainage and postoperative rehabilitation.

[0047] Example 2: Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.11 , Fig.12 , Fig.16 and Fig.17As shown, the ventricular drainage device also includes: a fixing frame 11, a suction cup is secretly turned on the back of the fixing frame 11, and the fixing frame 11 is adsorbed on the wall or the bed through the suction cup. A fixing box 12 is fixedly connected to one side of the fixing frame 11, and a sealing box 13 is inserted into the inner wall of the fixing box 12. The drainage head 9 is located at the end of the fixing box 12 and the sealing box 13 away from the fixing frame 11. The drainage bag 7 is located in the fixing frame 11. The outer surface of the drainage tube 8 is fixedly connected to a limiting ring 14, and two limiting rings 14 are provided. The limiting rings 14 are adapted to the two ends of the fixing box 12 and the sealing box 13. A top plate 16 is fixedly connected inside the sealing box 13, and the drainage tube 8 passes through the fixing box 12 and The sealing box 13 is provided, and the length of the drainage tube 8 is greater than that of the fixed box 12 and the sealing box 13; a pushing mechanism 15 is installed in the fixed box 12, which is used to reciprocate and push the drainage tube 8. The pushing mechanism 15 is arranged in two groups, and the two groups of pushing mechanisms 15 have the same rotation speed and opposite movement directions. The pushing mechanism 15 includes a driving motor 1501 installed below the fixed box 12, and the output ends of the driving motor 1501 are fixedly connected to a rotating shaft 1502, and the top of the rotating shaft 1502 is fixedly connected to a main synchronous wheel 1503, and the outer surface of the main synchronous wheel 1503 is installed with a synchronous belt 1504. A supporting plate 1505 is fixedly connected to the fixed box 12, and the supporting plate 15 05 is rotatably connected with a slave synchronous wheel 1506, a groove 1507 is provided on the top of the supporting plate 1505, a synchronous belt 1504 is installed on the outer surface of the slave synchronous wheel 1506, the synchronous belt 1504 is located in the groove 1507, and a pushing plate 1508 is rotatably connected to the top of the synchronous belt 1504. The main synchronous wheel 1503 and the slave synchronous wheel 1506 are both located in the groove 1507, and the rotating shaft 1502 passes through the bottom of the fixed box 12 and the supporting plate 1505 and is rotatably connected with the fixed box 12 and the supporting plate 1505. The two pushing plates 1508 of the two groups of pushing mechanisms 15 are located on both sides of the drainage tube 8, which slightly squeeze the drainage tube 8. So that the drainage tube 8 produces a slight deformation; it also includes a limiting mechanism 17, which is arranged in the fixed box 12 and is used to limit the position of the pushing mechanism 15. The limiting mechanism 17 is arranged in two groups. The limiting mechanism 17 includes a slide groove 1703 opened on the top of the supporting plate 1505, and a limiting rod 1704 is fixedly connected in the slide groove 1703. A slider 1702 is slidably connected in the slide groove 1703. The top of the slider 1702 is fixedly connected to the limiting frame 1701, the limiting rod 1704 penetrates the slider 1702 and is slidably connected to the slider 1702, and the pushing plate 1508 is located in the limiting frame 1701 and fits with the limiting frame 1701.

[0048] When in use, first install the drainage tube 8 on the fixing box 12 through two limiting rings 14, so that the drainage tube 8 extends out of the fixing box 12 and leaves a margin, so that the medical staff can perform head care on the patient, and then cover the sealing box 13 on the fixing box 12, and fix the drainage tube 8 and the drainage bag 7 in connection, and place the drainage bag 7 in the fixing frame 11. At this time, the fixing frame 11 is adsorbed on the wall or the bed through the suction cup according to the position of the patient's head, and finally the drainage head 9 is inserted into the drainage point of the patient's head. While draining, the driving motor 1501 is started, so that the rotating shaft 1502 drives the main synchronous wheel 1503 to rotate, and then cooperates with the synchronous wheel 150 6 makes the synchronous belt 1504 move, and the movement of the synchronous belt 1504 will make the pushing plate 1508 move, and the movement of the pushing plate 1508 will make the limiting frame 1701 drive the slider 1702 to slide in the slide groove 1703, and when the pushing plate 1508 reaches the main synchronous wheel 1503 or the slave synchronous wheel 1506 and needs to turn, due to the setting of the main synchronous wheel 1503 or the slave synchronous wheel 1506 and the limiting frame 1701 and the rotation connection between the pushing plate 1508 and the synchronous belt 1504, the pushing plate 1508 will produce two directions of movement, one is to drive the limiting frame 1701 to continue to move forward, and the other is to drive the limiting frame 1701 to continue to move forward. The first is to slide in the limiting frame 1701. When the pushing plate 1508 passes through the main synchronous wheel 1503 or moves from the turning point of the synchronous wheel 1506 to the same direction as the flow direction of the liquid in the drainage tube 8, one end of the pushing plate 1508 extends out of the limiting frame 1701 to squeeze the drainage tube 8, and the other end of the pushing plate 1508 will still be in the limiting frame 1701 and will not leave the limiting frame 1701. In the process of squeezing the drainage tube 8, the pushing plate 1508 will always be perpendicular to the drainage tube 8. In the process of squeezing the drainage tube 8, the blockage inside the drainage tube 8 will be pushed to move, so that the pushing plate 1508 will push the blockage adhering to the inner wall of the drainage tube 8 along the drainage direction. It is pushed towards the extrusion. This is because when the drainage tube 8 is squeezed, the drainage tube 8 will be deformed, and the blood clots and protein deposits adhered to the inner wall of the drainage tube 8 will be partially separated from the drainage tube 8 due to the deformation of the drainage tube 8, and the blood clots and protein deposits can also be deformed under the extrusion of the pushing plate 1508, so that the blood clots and protein deposits can pass through the drainage tube 8, thereby avoiding the continuous accumulation of blood clots and protein deposits, reducing the probability of blockage of the drainage tube 8, preventing the blockage of the drainage tube 8, resulting in a decrease in the flow rate of the liquid inside the drainage tube 8, and causing an increase in the patient's intracranial pressure, thereby ensuring the smoothness of the drainage and providing good protection for the patient.

When the magnetic sheet 1804 is aligned with the magnetic plate 1805, the magnetic plate 1805 will slide in the direction of the magnetic sheet 1804 under the action of the magnetic attraction force, and then the knocking head 1809 is driven to move away from the drainage tube 8 through the connecting rod 1806. When the magnetic sheet 1804 rotates away from the direction of the magnetic plate 1805, the magnetic plate 1805 will slide in the direction away from the magnetic sheet 1804 under the action of the knocking spring 1807, and then the knocking head 1809 hits the drainage tube 8 through the connecting rod 1806.

[0052] When the sealing box 13 is installed on the fixed box 12, the plug post 1913 will be inserted into the plug box 1912. When the rotating shaft 1502 rotates, the rotation of one of the rotating shafts 1502 will drive the transmission wheel 1901 to rotate, and then drive the lower rotating rod 1904 to rotate through the belt 1902 and the transmission wheel 2 1903. The rotation of the lower rotating rod 1904 will drive the lower reciprocating plate 1905 to rotate, so that the lower reciprocating plate 1905 drives the lower rubbing plate 1907 to move back and forth under the action of the lower slide plate 1922, the through groove 20 and the limiting column 21 through the lower circular frame 1906, and in this process, the lower rotating rod 190 When the upper rotating rod 1918 rotates, the upper reciprocating plate 1919 is driven to rotate, so that the upper reciprocating plate 1919 drives the upper rubbing plate 1921 on the upper slide plate 1923, the through slot 20 and the limit column 1913. 21, and the upper rubbing plate 1921 and the lower rubbing plate 1907 are staggered at the same speed. The upper rubbing plate 1921 and the lower rubbing plate 1907 that staggered at the same speed rub the drainage tube 8, and the rubbing distance is short. During the rubbing process, the setting of the limiting ring 14 will not pull the drainage tube 8 at both ends of the fixed box 12 and the sealing box 13 into the fixed box 12 and the sealing box 13, so that the blood clots formed after the operation in the drainage tube 8 and the protein deposits in the cerebrospinal fluid not only move in the drainage direction, but also move perpendicular to the drainage direction, which can destroy the blood clots and protein deposits in the cerebrospinal fluid that enter the drainage tube 8. The inherent form of brain deposition further reduces the probability of blood clots formed after surgery and protein deposits in the cerebrospinal fluid adhering to the inner wall of the drainage tube 8. In addition, since the lower kneading plate 1907 and the upper kneading plate 1921 can be made of thermal insulation rubber, the lower kneading plate 1907 and the upper kneading plate 1921 made of thermal insulation rubber can insulate the drainage tube 8 to a certain extent, slowing down the cooling rate of the brain fluid drained by the drainage tube 8, thereby slowing down the coagulation rate of blood clots and protein deposition, so that the fluid drained in the drainage tube 8 has good fluidity, thereby further reducing the probability of blockage of the drainage tube 8 and ensuring the quality of drainage of the drainage tube 8.

[0053] The working principle is as follows: Based on Example 1, before the drainage head 9 is inserted into the drainage point of the patient's head, the drainage tube 8 is first installed on the fixing box 12 through two limiting rings 14, so that the drainage tube 8 extends out of the fixing box 12 and leaves a margin, so that the medical staff can perform head care on the patient. Then, the sealing box 13 is covered on the fixing box 12, and the plug column 1913 is inserted into the plug box 1912, and the drainage tube 8 is fixedly connected with the drainage bag 7, and the drainage bag 7 is placed in the fixing frame 11. At this time, the fixing frame 11 is adsorbed on the wall through the suction cup according to the position of the patient's head. The patient is placed on the body or bed, and finally the drainage head 9 is inserted into the drainage point of the patient's head. While draining, the driving motor 1501 is started, so that the rotating shaft 1502 drives the main synchronous wheel 1503 to rotate, and then cooperates with the slave synchronous wheel 1506 to move the synchronous belt 1504. The movement of the synchronous belt 1504 will cause the pushing plate 1508 to move. The movement of the pushing plate 1508 will cause the limiting frame 1701 to drive the slider 1702 to slide in the slide groove 1703, and when the pushing plate 1508 reaches the main synchronous wheel 1503 or the slave synchronous wheel 1506 needs to turn, Due to the arrangement of the main synchronous wheel 1503 or the slave synchronous wheel 1506 and the limit frame 1701 and the rotational connection between the pushing plate 1508 and the synchronous belt 1504, the pushing plate 1508 will move in two directions, one is to drive the limit frame 1701 to continue to move forward, and the other is to slide in the limit frame 1701. When the pushing plate 1508 passes through the main synchronous wheel 1503 or the turning point of the slave synchronous wheel 1506 and moves to the same direction as the flow direction of the liquid in the drainage tube 8, one end of the pushing plate 1508 extends out of the limit frame 1701 to squeeze the drainage tube 8. , the other end of the pushing plate 1508 will still be in the limiting frame 1701 and will not be separated from the limiting frame 1701, and the pushing plate 1508 will always be perpendicular to the drainage tube 8 during the operation and extrusion process. When the pushing plate 1508 is moving, when the pushing plate 1508 is on the inner side and in the same direction as the flow direction of the liquid in the drainage tube 8, the pushing plate 1508 will squeeze the drainage tube 8, and in the process of squeezing the drainage tube 8, the blockage inside the drainage tube 8 will be pushed to move, so that the pushing plate 1508 squeezes and pushes the blockage adhering to the inner wall of the drainage tube 8 in the drainage direction;

[0054] During this process, the sliding of the slider 1702 in the slide groove 1703 causes the gear 1802 to rotate under the action of the teeth set in the slide groove 1703, and then drives the magnetic sheet 1804 to rotate through the roller 1803, so that the magnetic sheet 1804 intermittently aligns with the magnetic plate 1805. When the magnetic sheet 1804 is aligned with the magnetic plate 1805, the magnetic plate 1805 will slide in the direction of the magnetic sheet 1804 under the action of the magnetic attraction force, and then drive the knocking head 1809 to move away from the drainage tube 8 through the connecting rod 1806. When the magnetic sheet 1804 rotates away from the direction of the magnetic plate 1805, the magnetic plate 1805 will slide in the direction away from the drainage tube 8 under the action of the knocking spring 1807, and then the knocking head 1809 hits the drainage tube 8 through the connecting rod 1806. The drainage tube 8 is formed by the knocking head 1809, and the knocking head 1809 is located in front of the pushing plate 1508 in the forward direction of the drainage tube 8 when knocking the drainage tube 8, so that the drainage tube 8 vibrates, so that the blockage adhered to the inner wall of the drainage tube 8 can be separated from the drainage tube 8 under the vibration of the drainage tube 8, and it is avoided that when the pushing plate 1508 squeezes and pushes the blood clot or protein deposition, the blood clot or protein deposition accumulates at a certain place of the drainage tube 8 to cause blockage, and then cooperates with the squeezing and pushing of the pushing plate 1508, so that the blockage can be quickly discharged through the drainage tube 8, and the knocking of the knocking head 1809 causes the drainage tube 8 to vibrate, which reduces the probability that the blood clot formed after the intracranial surgery of the patient and the protein deposition in the cerebrospinal fluid adhere to the inner wall of the drainage tube 8 when the intracranial drainage fluid passes through the drainage tube 8;

[0055] At the same time, when the rotating shafts 1502 rotate, the rotation of one of the rotating shafts 1502 will drive the transmission wheel 1 1901 to rotate, and then drive the lower rotating rod 1904 to rotate through the belt 1902 and the transmission wheel 2 1903, and the rotation of the lower rotating rod 1904 will drive the lower reciprocating plate 1905 to rotate, so that the lower reciprocating plate 1905 drives the lower rubbing plate 1907 to move back and forth under the action of the lower slide plate 1922, the through groove 20 and the limiting column 21 through the lower return frame 1906, and in this process, when the lower rotating rod 1904 rotates, it will drive the transmission wheel 3 1908 to rotate, and then drive the lower reciprocating plate 1907 to move back and forth through the belt 1902 and the transmission wheel 2 1903. The second 1909 and the transmission wheel four 1910 drive the transmission shaft one 1911 to rotate, and then drive the transmission shaft two 1914 to rotate through the plug box 1912 and the plug column 1913, and the rotation of the transmission shaft two 1914 will drive the upper rotating rod 1918 to rotate through the transmission wheel five 1915, the belt three 1916 and the transmission wheel six 1917, and the rotation of the upper rotating rod 1918 will drive the upper reciprocating plate 1919 to rotate, so that the upper reciprocating plate 1919 drives the upper rubbing plate 1921 to move back and forth under the action of the upper slide plate 1923, the through groove 20 and the limit column 21 through the upper circular frame 1920, and the upper rubbing plate 1 The upper rubbing plate 1921 and the lower rubbing plate 1907 move in an interlaced manner at the same speed. The upper rubbing plate 1921 and the lower rubbing plate 1907 move in an interlaced manner at the same speed and rub the drainage tube 8, and the rubbing distance is relatively short. During the rubbing process, the setting of the limiting ring 14 will not pull the drainage tube 8 at both ends of the fixed box 12 and the sealing box 13 into the fixed box 12 and the sealing box 13, so that the blood clots formed after the operation in the drainage tube 8 and the protein deposits in the cerebrospinal fluid not only move in the drainage direction, but also move perpendicular to the drainage direction, which can destroy the inherent forms of the blood clots and the protein deposits in the cerebrospinal fluid entering the drainage tube 8. The probability of blood clots formed after surgery and protein deposits in the cerebrospinal fluid adhering to the inner wall of the drainage tube 8 is further reduced. In addition, since the lower kneading plate 1907 and the upper kneading plate 1921 can be made of thermal insulation rubber, the lower kneading plate 1907 and the upper kneading plate 1921 made of thermal insulation rubber can insulate the drainage tube 8 to a certain extent, slowing down the cooling speed of the brain fluid drained by the drainage tube 8, thereby slowing down the coagulation speed of blood clots and protein deposits, so that the fluid drained in the drainage tube 8 has good fluidity, thereby further reducing the probability of blockage of the drainage tube 8 and ensuring the drainage quality of the drainage tube 8;

[0056] And in this process, the knocking head 1809 will always knock the drainage tube 8, and the lower rubbing plate 1907 and the upper rubbing plate 1921 will always rub the drainage tube 8, so that the knocking head 1809 can knock various parts of the drainage tube 8 located in the fixed box 12, thereby reducing the probability of blood clots and protein deposits adhering to various parts of the drainage tube 8 located in the fixed box 12, and the knocking head 1809 moves and knocks, changing the flow rate of the drainage liquid in the drainage tube 8 at the knocking part of the knocking head 1809, thereby making the flow rate of the drainage liquid at the knocking part of the knocking head 1809 intermittently increase (this This is because squeezing temporarily reduces the effective cross-sectional area in the hose, thereby forming a temporary pressure difference near the squeezing point. According to the law of mass conservation in fluid dynamics, under steady-state flow conditions, the flow rate of the fluid is inversely proportional to the cross-sectional area. Therefore, when the cross-sectional area decreases, the flow rate must increase to keep the flow rate constant, which will lead to an increase in the flow rate), thereby increasing the impact force on the blockage, thereby further reducing the probability of blockage of the drainage tube 8, ensuring the smoothness of the drainage, providing good protection for the patient, and reducing the probability of intracranial hypertension, thereby effectively reducing the probability of complications caused by increased intracranial pressure;

[0057] After the drainage is completed, turn off the drive motor 1501, pull the drainage head 9 out of the patient's head and suture the patient's head, then turn off the controller 1, servo motor 4, laser tracker 2 and intracranial pressure monitor 3, and finally pour the liquid in the drainage bag 7 into the specified position.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
