Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a vascular catheter intervention information detection module and a detection method. Background Art

[0002] Interventional embolization surgery usually requires surgeons to first create a tiny incision on the human body surface using a puncture needle, catheter, and guidewire under the guidance and monitoring of a digital angiography machine, magnetic resonance imaging, and X-ray imaging equipment, then insert an angiography catheter from the incision to create a basic channel, then insert the guidewire into the catheter and ensure that the guidewire extends out of the front end of the catheter. Then, under the guidance of medical imaging, the operator inserts the guidewire catheter into the incision and enters the blood vessel along the angiography catheter. When reaching the vascular fork, one hand needs to fix the catheter to prevent it from moving, and then the other hand controls the tail end of the twisted guidewire to push the guidewire to a certain displacement. The twisted guidewire rotates at an angle and sends the guidewire to a certain position. Then, one hand holds the guidewire to prevent it from moving, and the other hand controls the tail end of the catheter to make the catheter move accordingly under the guidance of the guidewire.

[0003] The guidewire catheter manipulation device for interventional embolization surgery with application number 201911070085.X includes a guidewire catheter advancement module, a guidewire catheter rotation module, a retractable catheter mechanism, a movable angiography catheter locking mechanism, a guidewire force feedback module and a control system; the guidewire catheter advancement module includes a guidewire feed end micro-precision screw module and a catheter feed end micro-precision screw module, and is also provided with a press-to-move slider; the guidewire catheter rotation module consists of a hollow rotating dividing plate and a guidewire catheter locking device, but the catheter is easily contaminated by blood and slips when in use, thereby affecting the stability of the operation.

[0004] In addition, the blood in the blood vessels will flow out along the catheter, and the catheter needs to be constantly changed position during vascular intervention surgery. Therefore, the blood will slowly enter the detection drive component along the catheter. Due to the presence of blood, the driving wheel rotates, causing the catheter to slip easily when moving, and some blood will adhere to the driving wheel and auxiliary wheel and coagulate, which may easily cause damage to the catheter. When blood adheres to the driving wheel and auxiliary wheel, it is easy to be contaminated, which may easily cause the catheter to be contaminated, affecting the vascular intervention surgery.

At the same time, the resistance encountered by the catheter 2 when moving in the blood vessel can be detected with the assistance of the six-dimensional force sensor 14.

[0042] Rings 107 are provided on both sides of the shell 101, and rotating balls 108 are provided on the inner walls of the rings 107. The catheter 2 passes through the rings 107. A first bracket 109 is provided at the bottom end of the shell 101. A limiting groove 110 is provided on the first bracket 109. A moving block 111 is slidably provided in the limiting groove 110.

The auxiliary wheel 102 is closely attached to the lower end of the catheter 2 with the assistance of the compression spring 114, thereby ensuring the accuracy of the detection of the moving distance of the catheter 2.

[0043] A second bracket 112 is provided at the top of the inner part of the housing 101, and the driving wheel 104 is rotatably provided between the two second brackets 112. The transmission device 3 includes a first gear 301, which is coaxially provided at the side end of the driving wheel 104. A second gear 302 is rotatably provided at the side end of the second bracket 112. The first gear 301 and the second gear 302 are meshed and transmitted. An opening is provided on the housing 101, and the second gear 302 passes through the opening. A third gear 113 is provided at the output end of the driving motor 105. The third gear 113 is provided at the output end of the driving motor 105. The wheel 113 and the second gear 302 are meshed with each other. After the drive motor 105 is started, the output end of the drive motor 105 drives the rotation of the third gear 113. The rotation of the third gear 113 drives the rotation of the second gear 302 through the meshing transmission. The rotation of the second gear 302 drives the rotation of the first gear 301 through the meshing transmission. The first gear 301 is coaxially arranged on the side end of the drive wheel 104. Therefore, the rotation of the first gear 301 drives the rotation of the drive wheel 104, thereby providing power for the movement of the catheter 2.

[0044] A display screen 15 is provided at the top of the shell 101, and a support rod 16 is provided between the display screen 15 and the shell 101.

[0045] During use of the present invention, the mounting frame 5 is placed beside the patient, and the first slider 6 and the second slider 7 are slid at this time. The positions of the first slider 6 and the second slider 7 are adjusted and fixed according to the position of the patient undergoing vascular intervention surgery. When the catheter 2 needs to be intervened in the blood vessel, the catheter 2 is passed through the detection drive assembly 1, the outer sleeve 13, the stabilizing plate 12 and the six-dimensional force sensor 14. When the catheter 2 is intervened, the drive motor 105 is controlled with the assistance of the control panel 106 to start the drive motor 105. The output end of the drive motor 105 drives the rotation of the third gear 113. The rotation of the third gear 113 drives the rotation of the second gear 302 through meshing transmission. The rotation of the second gear 302 drives the rotation of the first gear 301 through meshing transmission. The first gear 301 is coaxially arranged at the side end of the driving wheel 104. Therefore, the rotation of the first gear 301 drives the rotation of the driving wheel 104. During the rotation of the driving wheel 104, it cooperates with the auxiliary wheel 102 to move the catheter 2.

[0046] When the catheter 2 moves in the blood vessel, it will encounter resistance when it encounters a bifurcation of the blood vessel. The resistance encountered by the catheter 2 when moving in the blood vessel will be detected by the six-dimensional force sensor 14, and the value detected by the six-dimensional force sensor 14 will be displayed on the display screen 15. In addition, the rotation speed of the auxiliary wheel 102 can be detected with the assistance of the rotation speed sensor 103. The distance moved by the catheter 2 can be obtained through data such as the rotation speed of the auxiliary wheel 102, the diameter of the auxiliary wheel 102 and the operating time of the drive motor 105. The distance moved by the catheter 2 will also be displayed in the form of data on the display screen 15, making the device more accurate when performing vascular intervention surgery.

[0047] When the catheter 2 moves in the collar 107, the rotating ball 108 is used to prevent the catheter 2 from contacting and rubbing with the collar 107, thereby preventing the catheter 2 from being damaged and thus preventing the catheter 2 from damaging the blood vessel when moving in the blood vessel.

[0048] When the auxiliary wheel 102 cooperates with the driving wheel 104 to move the catheter 2, the compression spring 114 is used to reduce slippage between the auxiliary wheel 102 and the catheter 2, thereby avoiding inaccurate detection and idling of the driving wheel 104, thereby improving the stability of the device.

[0049] Example 2

[0050] Based on the vascular catheter intervention information detection module of the above-mentioned embodiment 1, although the device can detect the moving distance of the catheter 2 and the resistance encountered by the catheter 2 in the blood vessel during use, the blood in the blood vessel will be discharged along the catheter 2 during the specific use of the device, and the catheter 2 needs to be constantly changed during the vascular intervention surgery, so the blood will slowly enter the detection drive component 1 along the catheter 2, and due to the presence of blood, the driving wheel 104 rotates to make the catheter 2 slip when moving, and part of the blood will adhere to the driving wheel 104 and the auxiliary wheel 102 and coagulate, which is easy to damage the catheter 2, and the blood is easy to be contaminated when it adheres to the driving wheel 104 and the auxiliary wheel 102, which is easy to contaminate the catheter 2, and affect the vascular intervention surgery. For this reason, we propose the following technical solutions:

[0051] like Figures 1 to 8As shown, the housing 101 is provided with auxiliary cleaning components 4 on both sides of the transmission device 3, and the auxiliary cleaning components 4 include a mounting rod 401, a liquid storage tank 402 is provided at the upper end of the mounting rod 401, a piston plate 403 is slidably provided in the liquid storage tank 402, a first magnet sheet is provided in the piston plate 403, an electromagnet 404 is provided at the lower end of the mounting rod 401, a limiting hole 405 is provided at the side end of the mounting rod 401, a moving rod 406 is limitedly slidably provided in the limiting hole 405, and the moving rod 406 is close to the electromagnet 404 A second magnet sheet is arranged on one side of the movable rod 406, a spring 407 is arranged on the side end of the movable rod 406, an upper cleaning block 408 is arranged on the side of the movable rod 406 away from the mounting rod 401, a connecting rod 409 is arranged on the side end of the movable rod 406 through a torsion spring, a lower cleaning block 410 is arranged on the lower end of the connecting rod 409, a mounting plate 411 is arranged on the upper cleaning block 408, a drain pipe 412 is arranged on the mounting plate 411, and the drain pipe 412 is connected to the liquid storage tank 402. When the driving motor 105 is running, the speed sensor 1 03 detects that the rotation speed of the auxiliary wheel 102 is zero, indicating that the blood adheres to the driving wheel 104 and the auxiliary wheel 102 to make them slip. At this time, the electromagnet 404 is energized, and the electromagnet 404 generates a magnetic force to generate an attraction force on the first magnet sheet in the piston plate 403, so that the piston plate 403 moves downward. After the electromagnet 404 is energized, a repulsive force is generated on the second magnet sheet at the side end of the moving rod 406, so that the moving rod 406 moves away from the mounting rod 401, so that the upper cleaning block 408 is attached to the driving wheel 104. The downward movement of the piston plate 403 will squeeze the saline in the liquid storage tank 402 out of the discharge pipe 412. As the driving wheel 104 rotates, the upper cleaning block 408 sticks to the driving wheel 104 to clean the blood, and the saline sprayed from the discharge pipe 412 can also assist in cleaning the blood, so as to ensure that the catheter 2 can move stably. At the same time, the movement of the moving rod 406 will also make the lower cleaning block 410 stick to the side end of the auxiliary wheel 102 to clean the auxiliary wheel 102, so as to ensure the stable movement of the catheter 2.

[0052] A baffle 115 is provided at the bottom end of the shell 101. There are multiple baffles 115. A feeding port 116 is provided at the lower end of each baffle 115. A discharge pipe 117 is provided at the lower end of the shell 101. A valve 118 is provided on the discharge pipe 117. A limit rod 413 is provided at the top end of the piston plate 403. The limit rod 413 passes through the shell 101. A channel is provided in the limit rod 413. A one-way valve is provided in the channel. The channel in the limit rod 413 is connected with the liquid storage tank 402. The cleaned blood mixed with saline falls on the bottom end of the shell 101. When the shell 101 is collided, the blood mixed with saline at the bottom end of the shell 101 will not be agitated with the assistance of the baffle 115, so as to avoid secondary contamination of the catheter 2. After the equipment is used, the valve 118 is opened to discharge the blood mixed with saline in the shell 101 from the discharge pipe 412, thereby improving the stability of the equipment.

[0053] During use of the present invention, the mounting frame 5 is placed beside the patient, and the first slider 6 and the second slider 7 are slid at this time. The positions of the first slider 6 and the second slider 7 are adjusted and fixed according to the position of the patient undergoing vascular intervention surgery. When the catheter 2 needs to be intervened in the blood vessel, the catheter 2 is passed through the detection drive assembly 1, the outer sleeve 13, the stabilizing plate 12 and the six-dimensional force sensor 14. When the catheter 2 is intervened, the drive motor 105 is controlled with the assistance of the control panel 106 to start the drive motor 105. The output end of the drive motor 105 drives the rotation of the third gear 113. The rotation of the third gear 113 drives the rotation of the second gear 302 through meshing transmission. The rotation of the second gear 302 drives the rotation of the first gear 301 through meshing transmission. The first gear 301 is coaxially arranged at the side end of the driving wheel 104. Therefore, the rotation of the first gear 301 drives the rotation of the driving wheel 104. During the rotation of the driving wheel 104, it cooperates with the auxiliary wheel 102 to move the catheter 2.

[0054] When the catheter 2 moves in the blood vessel, it will encounter resistance when it encounters a bifurcation of the blood vessel. The resistance encountered by the catheter 2 when moving in the blood vessel will be detected by the six-dimensional force sensor 14, and the value detected by the six-dimensional force sensor 14 will be displayed on the display screen 15. In addition, the rotation speed of the auxiliary wheel 102 can be detected with the assistance of the rotation speed sensor 103. The distance moved by the catheter 2 can be obtained through data such as the rotation speed of the auxiliary wheel 102, the diameter of the auxiliary wheel 102 and the operating time of the drive motor 105. The distance moved by the catheter 2 will also be displayed in the form of data on the display screen 15, making the device more accurate when performing vascular intervention surgery.

[0055] When the catheter 2 moves in the collar 107, the rotating ball 108 is used to prevent the catheter 2 from contacting and rubbing with the collar 107, thereby preventing the catheter 2 from being damaged and thus preventing the catheter 2 from damaging the blood vessel when moving in the blood vessel.

[0056] When the auxiliary wheel 102 cooperates with the driving wheel 104 to move the catheter 2, the compression spring 114 is used to reduce slippage between the auxiliary wheel 102 and the catheter 2, thereby avoiding inaccurate detection and idling of the driving wheel 104, thereby improving the stability of the device.

[0057] When the driving motor 105 is running stably and the driving wheel 104 is running stably, if the detection value of the speed sensor 103 decreases, it indicates that slippage has occurred between the driving wheel 104 and the catheter 2. At this time, the device controls the electromagnet 404 to be energized. After the electromagnet 404 is energized, it will generate a magnetic attraction to the first magnet sheet in the piston plate 403, causing the piston plate 403 to descend. After the piston plate 403 descends, it cooperates with the liquid storage tank 402 to squeeze the physiological saline in the liquid storage tank 402 through the drainage pipe 412. The physiological saline discharged from the drainage pipe 412 will be sprayed on the driving wheel 104 to flush the blood adhered to the driving wheel 104. Since the diameter of the drainage pipe 412 is small, the piston plate 403 will continue to slowly descend.

[0058] When the electromagnet 404 is energized, it will generate a repulsive force on the second magnet sheet at the side end of the moving rod 406, causing the moving rod 406 to move in a direction away from the mounting rod 401. The movement of the moving rod 406 will cause the upper cleaning block 408 to press on the driving wheel 104. As the driving wheel 104 rotates, the upper cleaning block 408 will wipe the driving wheel 104 to clean the adhered blood, thereby ensuring stable transmission between the driving wheel 104 and the catheter 2. When the moving rod 406 moves, it will drive the movement of the mounting plate 411, and the movement of the mounting plate 411 will cause the drain pipe 412 to bend. On the one hand, the bending of the drain pipe 412 will change the spraying direction of the saline solution. On the other hand, the bending of the drain pipe 412 will change the diameter of the drain pipe 412, thereby changing the flow rate of the saline solution discharged from the drain pipe 412, thereby enabling the sprayed saline solution to better clean the blood on the driving wheel 104, thereby improving the stability of the equipment.

[0059] Before the moving rod 406 moves, since the moving rod 406 is connected to the connecting rod 409 by a torsion spring, the lower cleaning block 410 is attached to the auxiliary wheel 102 at this time, ensuring that there is no blood adhering to the outside of the auxiliary wheel 102, so that the speed sensor 103 indirectly detects the accuracy of the movement of the catheter 2. After the moving rod 406 moves, as the physiological saline is sprayed, the physiological saline mixed with blood will adhere to the auxiliary wheel 102 downward. In order to ensure the detection accuracy of the speed sensor 103, the movement of the moving rod 406 increases the force of the lower cleaning block 410 adhering to the auxiliary wheel 102 through the movement of the torsion spring and the connecting rod 409, thereby ensuring that when the auxiliary wheel 102 rotates, the lower cleaning block 410 can clean the physiological saline, blood and stubborn impurities on the auxiliary wheel 102, thereby ensuring the detection accuracy of the speed sensor 103.

[0060] The cleaned blood mixed with saline solution falls to the bottom of the shell 101. When the shell 101 is hit, the blood mixed with saline solution at the bottom of the shell 101 will not be agitated with the help of the baffle 115, thereby avoiding secondary contamination of the catheter 2. After the equipment is used, the valve 118 is opened to discharge the blood mixed with saline solution in the shell 101 from the drain pipe 412, thereby improving the stability of the equipment.

[0061] It should be noted that when the upper cleaning block 408 is pressed on the driving wheel 104 , the rotation of the driving wheel 104 will not be affected; and when the lower cleaning block 410 is pressed on the auxiliary wheel 102 , the rotation of the auxiliary wheel 102 will not be affected.

[0062] After the equipment is used, disinfectant is added into the liquid storage bin 402 through the action of the channel in the limit rod 413, and then the auxiliary wheel 102 is pressed on the driving wheel 104 with the assistance of the compression spring 114, the driving motor 105 is started, and the electromagnet 404 is intermittently energized, so that the driving wheel 104 rotates with the auxiliary wheel 102, and as the electromagnet 404 is intermittently energized, the drainage pipe 412 intermittently sprays disinfectant, and the upper cleaning block 408 moves back and forth, so that the amount of disinfectant sprayed from the drainage pipe 412 changes, the upper cleaning block 408 intermittently presses on the driving wheel 104, and the force of the lower cleaning block 410 pressing on the auxiliary wheel 102 also changes, thereby disinfecting the driving wheel 104 and the auxiliary wheel 102 and cleaning impurities, and the disinfectant that falls will also disinfect and clean the bottom of the shell 101, thereby reducing the generation of medical waste.

[0063] When the physiological saline is sprayed on the driving wheel 104 and falls on the auxiliary wheel 102, the physiological saline will dilute the blood on the driving wheel 104 and the auxiliary wheel 102. On the one hand, it will increase the friction between the driving wheel 104, the auxiliary wheel 102 and the catheter 2, so that the driving wheel 104 can stably transmit the catheter 2 when rotating. On the other hand, it will make it easier to clean the upper cleaning block 408 and the lower cleaning block 410, ensuring the stability of the catheter 2.

[0064] A cleaning sponge is also provided on the connecting rod 409. The sprayed physiological saline will also drip into the cleaning sponge on the connecting rod 409 during the falling process. When the catheter 2 passes through the cleaning sponge on the connecting rod 409, the blood adhering to the catheter 2 is cleaned by the cleaning sponge, so that the friction force of the catheter 2 is kept stable when passing between the driving wheel 104 and the auxiliary wheel 102, thereby improving the stability of the equipment.

[0065] The present invention provides components such as an electromagnet 404, a piston plate 403, an upper cleaning block 408, a torsion spring and a lower cleaning block 410, so that when the device is in operation, when the speed sensor 103 detects that slippage occurs between the driving wheel 104 and the catheter 2, the device energizes the electromagnet 404, and after the electromagnet 404 is energized, the piston plate 403 is lowered under the action of magnetic force, so that the drainage pipe 412 discharges physiological saline to clean the driving wheel 104, and under the influence of the magnetic force, the upper cleaning block 408 is attached to the driving wheel 104, and the lower cleaning block 410 is attached to the auxiliary wheel 102, so that the driving wheel 104 and the auxiliary wheel 102 are cleaned with the cooperation of physiological saline, thereby ensuring the stability of the operation of the device, and after the use of the device is completed, disinfectant water is introduced into the liquid storage tank 402, and the corresponding operating device disinfects the various components in the shell 101, thereby reducing the generation of medical waste and improving the effect of the use of the device.
