Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an interventional surgery robot system. Background Art

[0002] Vascular interventional surgery is a minimally invasive procedure used to treat vascular diseases or cancer. It involves inserting a thin catheter (catheter) with a diameter of several millimeters or less through the blood vessels percutaneously to the lesion site, primarily based on X-ray fluoroscopy. The catheter then reaches the target organ for treatment. Currently, representative vascular interventional procedures performed around the world, including Korea, include transarterial chemoembolization (TACE) for liver cancer, percutaneous angioplasty, and stent implantation for aortic disease.

[0003] Catheters and other elongated medical devices (EMDs) are used in minimally invasive medical procedures for the diagnosis and treatment of various vascular conditions, including neurovascular intervention (NVI) (also known as neurointerventional procedures), percutaneous coronary intervention (PCI), and peripheral vascular intervention (PVI). These procedures typically involve navigating a guidewire through the vasculature and advancing a catheter over the guidewire to deliver the therapy. The catheterization procedure begins by gaining access to an appropriate vessel (such as an artery or vein) through an introducer sheath using standard percutaneous techniques. Through the introducer sheath, a sheath or guide catheter is then advanced over the diagnostic guidewire to the primary location, such as the internal carotid artery for NVI, the coronary ostium for PCI, or the superficial femoral artery for PVI. A guidewire appropriate for the vasculature is then navigated through the sheath or guide catheter to the target location in the vasculature. In some cases, such as in tortuous anatomy, a support catheter or microcatheter is inserted over the guidewire to assist in guiding the guidewire. The physician or operator can use an imaging system (e.g., a fluoroscope) to obtain a movie with contrast injection and select a fixed frame to use as a roadmap to navigate the guidewire or catheter to the target location, such as a lesion. While the physician delivers the guidewire or catheter, contrast-enhanced images can also be obtained, allowing the physician to verify that the device is moving along the correct path toward the target location. While visualizing the anatomy using fluoroscopy, the physician manipulates the proximal end of the guidewire or catheter to guide the distal tip toward the lesion or target anatomical location into the appropriate vessel and avoid advancement into side branches.

[0004] The current interventional surgical robot system has a single function and cannot meet the needs. Summary of the Invention

[0046] Compared with the prior art, the interventional surgical robot system provided by the present invention has the following beneficial effects:

[0047] 1. The drive mechanism is provided with an axially penetrating opening, and the guide wire is installed from the opening. Compared with the method of threading the wire from one end to the other end, it is more efficient and less difficult to install.

[0048] 2. The guide wire is rotated by the rotation of the rotating gear, and the guide wire is axially transported by the rotation of the conveying gear.

[0049] 3. When the rotation speed of the rotating gear and the conveying gear is the same, the guide wire performs rotational motion, which makes it easier to pass through tortuous and bifurcated blood vessels; when the rotation speed of the rotating gear and the conveying gear is different, the guide wire performs axial and rotational motion at the same time. Adjusting the speed and direction of the rotating gear and the conveying gear can control the speed and direction of the guide wire's rotational and axial motion.

[0050] 4. The conveyor gear drives the conveyor body to transport the guide wire. The guide wire is inserted into the conveyor body and the conveyor gear through the opening. During the conveying process, the conveyor gear rotates continuously, and the opening of the conveyor gear and the opening of the conveyor body separate. When it is necessary to remove the guide wire, the clutch mechanism separates the transmission mechanism and the conveyor gear. While the conveyor gear continues to rotate, the guide wire will not move forward or backward.

[0051] 5. The spring keeps the helical gear and the driving cylindrical gear engaged, allowing the guide wire to be delivered during the rotation of the delivery gear. When the push rod is lifted, the helical gear and the driving cylindrical gear separate, and the driving cylindrical gear remains stationary during the rotation of the helical gear.

[0052] 6. The first motor drives the crank to rotate, and the crank drives the slider to move radially to drive the push rod to move up and down, thereby controlling the state of the clutch mechanism.

[0053] 7. Turn the knob to drive the gate to move up and down. The downward movement can press the guide wire into the specified position.

[0054] 8. The opening of the upper mounting groove is larger than the lower mounting groove. When the gate is in the upper mounting groove, the guide wire can be placed under the gate to facilitate pressing the guide wire in. The opening of the lower mounting groove is equal to the thickness of the gate to prevent the guide wire from detaching from the gate during the downward pressing process.

[0055] 9. Tighten the spring to keep the gate close to the second stopper, so that there is a gap between the upper mounting groove and the gate to facilitate the insertion of the guide wire.

[0056] 10. Lock the guide shaft in the lock hole by turning the locking plate buckle to prevent the gate from rising and the guide wire from detaching from the gate during the guide wire delivery process.

[0057] 11. During the rising process of the gate, the rotary dial block rotates counterclockwise. A push block is provided on the knob dial block. The push block pushes the push block protrusion of the adjusting rod to the right, pressing the silicone roller away from the driving silicone roller to release the guide wire.

[0058] 12. The upper and lower gear discs are engaged by controlling the lifting and lowering of the lower gear disc. In the engaged state, the second motor rotates to drive the upper gear disc to rotate, thereby driving the catheter to move. In the disengaged state, the catheter can be manually pulled.

[0059] 13. The rotation of the third motor drives the movement of the lifting push rod, which has an inclined groove. The lifting slider moves up and down along the inclined groove, thereby driving the lower gear plate to move up and down.

[0060] 14. The elastic force of the thrust spring moves the lifting slider upward so that the lifting slider is always connected to the upper wall of the inclined groove, which can better perform lifting.

[0061] 15. The support mechanism is supported on the bed. The upper arm, middle arm and small arm of the support can rotate 360 degrees around the z-axis direction. The middle arm of the support can be raised and lowered and tilted along the height direction of the z-axis.

[0062] 16. The support mechanism is fixed and loosened by turning the cam wrench. The support column can prevent the mechanism from tilting and tipping over.

[0063] 17. The state of the connecting rod is controlled by the buffer cylinder. When unloaded, the connecting rod is set horizontally. When loaded, the end of the connecting rod away from the bracket arm tilts downward, the buffer cylinder contracts, and the tilt angle is controlled by the lower limit pin.

[0064] 18. The damping friction plate allows the extension rod to rotate only when there is a certain amount of energy, and the mechanism does not shake after the force is released. The encoder can feedback the rotation angle, prompting the operator to adjust to the appropriate position within a certain range.

[0065] 19. The rotation of the bracket arm and the bracket middle arm is controlled by the locking tongue mechanism. When the first locking tongue is engaged with the brake large tooth and the second locking tongue is engaged with the brake middle tooth, the bracket arm and the bracket middle arm cannot rotate. When separated, they can rotate again.

[0066] 20. Manual and automatic are integrated, with a high degree of automation and good safety. A micro switch is added to the control mechanism. A contact is provided below the first micro switch and the second micro switch respectively. A trigger block is provided on the first movable seat and the second movable seat respectively, and a bevel structure is provided above the trigger block. When the first connecting plate and the second connecting plate move toward each other, the motor stops moving when the first movable seat triggers the contact; when the first connecting plate and the second connecting plate move away from each other, the motor stops moving when the second movable seat triggers the contact. Springs are provided on the first lock tongue and the second lock tongue, and a square nut is provided on the movable seat, realizing the function of unlocking and locking by rotating the manual release mechanism.

[0067] 21. A gear is mounted on the base and a rack is mounted on the flexible tube. The motor drives the gear, which in turn drives the flexible tube. The motor provides high control precision and a self-locking function, allowing the flexible tube to be positioned in a fixed position without the need for additional locking tools.

[0068] 22. A rack and a long slit are provided on the flexible tube. When the rack and the gear are engaged, the position of the long slit is fixed and will not rotate. The guide wire will not deviate from the long slit and bend or become difficult to enter the flexible tube.

[0069] 23. The flexible catheter material is one or more components of PDFE or PTFE, and has self-lubricating and bendable properties.

[0070] 24. By setting an adapter and setting a clamping groove in the adapter, the main part of the hemostatic valve can be adapted to the clamping groove and clamped by the clamping groove, and the hollow part can be adapted to the adjustment position of the hemostatic valve. When the hemostatic valve is fixed on the adapter, the adjustment position of the hemostatic valve is just located in the hollow part, which is convenient for the operator to control the opening and closing of the hemostatic valve by rotating the adjustment position of the hemostatic valve through the hollow part, and the operation is more convenient. The flexible catheter is hollow inside and is used to supply pipelines, guide wires and other equipment to pass through the hemostatic valve and protect the equipment. The connector and the flexible catheter and adapter are all detachably connected, which is convenient for disassembly and replacement, and maintenance. A catheter sheath is provided to cover and protect the notch, thereby improving the bending resistance of the notch position and avoiding damage to the flexible catheter caused by bending.

[0071] 25. By providing an elastic clamp body and providing a clamping groove on the elastic clamp body, the clamping groove can cooperate with the main part of the Y-type hemostatic valve to fix the hemostatic valve, and the adjustment part of the fixed hemostatic valve is just located in the hollow part, which is convenient for the operator to control the opening and closing of the hemostatic valve by rotating the adjustment part of the hemostatic valve, and adjust the position of the elastic clamp body through the adjustment mechanism to make it close to or away from the clamping groove, and adjust the length of the clamping groove so that it can be suitable for hemostatic valves of various lengths, with wider applicability.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. Example 1:

[0134] See Figure 1 、 Figure 2 and Figure 6In an optional embodiment, an embodiment of the present invention provides a guide wire drive device, comprising a conveying body 10 and a rotating gear 11 mounted on one side of the conveying body 10. The conveying gear 12 is rotatably mounted on the other side of the conveying body 10. The conveying body 10, the rotating gear 11, and the conveying gear 12 are axially penetrated by an opening 13, and the guide wire is clamped into the drive device through the opening 13. In the initial state, the opening 13 is located in the upper half of the drive mechanism. The height of the opening 13 is equal to the radius of the rotating gear 11, and the size of the opening 13 is larger than the guide wire. A conveying mechanism 14 driven by the conveying gear 12 is provided on the conveying body 10. The conveying gear 12 drives the conveying mechanism 14 to convey the guide wire through a transmission mechanism 20. The transmission mechanism 20 includes a clutch mechanism 24 that can be disengaged from the conveying gear 12 during the lifting process. A wire clamping mechanism is provided on the conveying body 10 for pressing the guide wire into the conveying mechanism 14 along the opening 13. The opening 13 and the guide wire are relatively small, and manual insertion is difficult. An additional wire clamping mechanism is used to clamp the guide wire from above the opening 13 into the conveying mechanism 14 for conveying.

[0135] Preferably, the rotating gear 11 and the conveying gear 12 are respectively arranged on the left and right sides of the conveying body 10, and the rotating gear 11 and the conveying body 10 are fixed together, and the rotating gear 11 will rotate together with the conveying body 10. The diameters of the rotating gear 11 and the conveying gear 12 are equal. Among them, the rotation of the rotating gear 11 drives the driving mechanism to rotate, which can make the guide wire change its direction and position to facilitate the passage in the tortuous and bifurcated blood vessels. The rotation of the conveying gear 12 drives the guide wire to move forward or backward in the blood vessel. The two are used in combination to better control the movement of the guide wire. The overall shape of the conveying body 10 is circular and the same size as the rotating gear 11. The rotation and axial movement of the guide wire require separate control structures for control. Such a setting has stronger integrity, smaller size, easier placement and beautiful appearance. The guide wire can be any tubular or strip-shaped medium that can be transported in the blood vessel of the percutaneous interventional device. The guide wire is not limited to the conveying medium.

[0136] See Figure 2 and Figure 4 In an optional embodiment, the conveying mechanism 14 includes a driving gear 15 driven by the conveying gear 12, a driving silicone roller 16 driven by the driving gear 15, and a pressing silicone roller 17 corresponding to the driving silicone roller 16. A transmission mechanism 20 is provided between the driving gear 15 and the conveying gear 12.

[0137] The driving gear 15 is coaxially mounted with the driving silicone roller 16, while the compression silicone roller 17 corresponds to the driving silicone roller 16 and compresses the guidewire. There is one driving gear 15 and one compression silicone roller 17. The rotation of the driving gear 15 drives the synchronous rotation of the driving silicone roller 16. The friction of the driving silicone roller 16 drives the rotation of the driving silicone roller 16, which compresses the guidewire and moves it. The silicone material used contacts the guidewire to prevent hard contact and wear on the guidewire.

[0138] There can be two or more driving gears 15. Power is transmitted between the driving gears 15 via an intermediate gear 23. The tooth diameter of the intermediate gear 23 is smaller than that of the driving gear 15, ensuring smoother transmission. Preferably, there are three driving gears 15, evenly distributed axially on the drive mechanism, providing more contact points, more stable guidewire delivery, and less likely to cause guidewire bending during delivery.

[0139] See Figure 3 In an optional embodiment, the rotating gear 11 is a helical gear, and a first small helical gear 18 is connected to the rotating gear 11. The rotating gear 11 is fixed to the conveying body 10, and a gear end is provided on the side away from the conveying body 10. The rotating gear 11 is automatically driven by the first small helical gear 18, thereby driving the rotation of the conveying body 10 and the guidewire.

[0140] See Figure 3 In an optional embodiment, the conveying gear 12 is a double-sided helical gear. The end of the conveying gear 12 away from the conveying body 10 is connected to a second helical gear 19, and the end of the conveying gear 12 closer to the conveying body 10 is connected to a transmission mechanism 20. The conveying gear 12 is rotatably connected to the conveying body 10. Gear surfaces are provided on both the left and right sides of the conveying gear 12. The end away from the conveying body 10 meshes with the second helical gear 19, which automatically controls the rotation of the conveying gear 12 and thus the delivery status of the guidewire.

[0141] See Figure 4 In an optional embodiment, the transmission mechanism 20 includes a helical gear 21 and a driving cylindrical gear 22 coaxially mounted with the helical gear 21. The driving cylindrical gear 22 drives the driving gear 15 to rotate. The helical gear 21 and the driving cylindrical gear 22 are connected by a fixed shaft and have the same angular velocity. The driving cylindrical gear 22 is directly or indirectly connected to the rightmost driving gear 15.

[0142] When there are preferably three driving gears 15, the driving cylindrical gear 22 can be directly connected to the driving gears 15, and the thickness of the rightmost driving gear 15 can be thicker. The lower half of the rightmost driving gear 15 meshes with the driving cylindrical gear 22, and the upper half meshes with the intermediate gear 23. In this case, the two left driving gears 15 do not need to mesh with the driving cylindrical gear 22 and can be thinner. Other cases where there is only one driving gear 15 and the driving cylindrical gear 22 is indirectly connected to the driving gear 15 are merely the addition or subtraction of gears or other mechanical structures and are not detailed in the embodiments.

[0143] See Figure 5 In an optional embodiment, the clutch mechanism 24 includes a clutch protrusion 241 that engages with the helical gear 21 and a push rod 242 for mounting the clutch protrusion 241. The push rod 242 serves as the central axis of the clutch protrusion 241, and the helical gear 21 and the driving cylindrical gear 22 are coaxially connected to the push rod 242. The helical gear 21 has a through hole in the center for inserting the push rod 242. The clutch protrusion 241 includes a disk 244 and a boss 243 disposed at the bottom of the disk 244. Preferably, there are two bosses 243, evenly distributed on the bottom of the disk 244. The helical gear 21 is provided with a groove 245 that mates with the boss 243. The groove 245 is a cross-shaped groove. The helical gear 21 is rotatably connected to a mounting base 25, which is mounted on the conveying body 10. The mounting base 25 is Z-shaped and fixed to the bottom of the conveying body 10.

[0144] In an optional embodiment, the clutch protrusion 241 is provided between the helical gear 21 and the driving cylindrical gear 22, and a spring is provided between the driving cylindrical gear 22 and the conveying body. The top of the push rod 242 is provided with a spring receiving cavity.

[0145] See Figure 1 and Figure 9 In an optional embodiment, the conveying body 10 includes a base 30, a first stopper 31 and a second stopper 32 mounted on the base 30, a mounting groove 33 is formed between the first stopper 31 and the second stopper 32, and the wire clamping mechanism includes a knob block 34 rotatably mounted on the second stopper 32 and a gate plate 35 connected to the knob block 34, the gate plate 35 is tightly attached to the second stopper 32 and moves up and down in the mounting groove 33. The guide wire is placed in the mounting groove 33 and below the gate plate 35. The knob block 34 is rotated clockwise to press the guide wire down to the specified position. This solves the problem that the guide wire is relatively thin and it is troublesome to place it manually.

[0146] See Figure 9In an optional embodiment, the mounting groove 33 includes an upper mounting groove 331 and a lower mounting groove 332 disposed below the upper mounting groove 331. The opening of the upper mounting groove 331 is larger than the lower mounting groove 332. The smooth connection between the upper mounting groove 331 and the lower mounting groove 332 prevents the gate plate 35 from getting stuck during its descent. The opening of the lower mounting groove 332 is adapted to, and is approximately equal to, the thickness of the gate plate 35. When the guidewire is placed in the lower mounting groove 332, the gate plate 35 presses downward, pressing the guidewire to the designated position without getting stuck on the inner wall.

[0147] See Figure 10 In an optional embodiment, a guide block 36 is further provided on the second stopper 32. A guide groove for the guide block 36 is provided on the second stopper 32, and the guide block 36 moves up and down along the guide groove. The guide block 36 is driven up and down by the knob 34, and the guide block 36 drives the gate plate 35 up and down. The guide block 36 and the gate plate 35 are connected by a plurality of connecting shafts 37. The second stopper 32 is provided with a guide groove for the connecting shaft 37, which prevents the connecting shaft 37 from shaking left and right and moves only in the height direction. A tension spring is provided on the connecting shaft 37 to keep the gate plate 35 in close contact with the second stopper 32. There is a gap between the gate plate 35 and the upper mounting groove 331, and the guide wire is inserted into the lower mounting groove 332 through the gap. As the gate plate 35 moves downward, it slowly enters the lower mounting groove 332 from the upper mounting groove 331 until the guide wire is pressed into the designated position for delivery.

[0148] See Figure 10 In an optional embodiment, the second stopper 32 is provided with a plurality of guide grooves 323, and the gate plate 35 is provided with ribs 351 that mate with the guide grooves 323. The ribs 351 move up and down along the guide grooves 323, increasing the contact area and ensuring smoother movement without tilting, thereby enhancing the guidewire compression effect. Due to the small size of the overall device, the ribs 351 also increase the strength of the gate plate 35, making it less susceptible to breakage.

[0149] See Figure 8 and Figure 10In an optional embodiment, the second stopper 32 is provided with an arcuate guide groove 321, and the knob selector 34 is provided with a guide shaft 341 that moves along the arcuate guide groove 321. A hook-shaped locking hole 322 is provided at the bottom end of the arcuate guide groove 321. The portion of the guide shaft 341 within the arcuate guide groove 321 is notched, giving the end of the guide shaft 341 a semicircular shape that moves within the arcuate guide groove 321. The guide shaft 341 is rotatably mounted on the knob selector 34 and secured to the locking hole 322 upon rotation. A locking plate 342 is provided on the guide shaft 341 to control its rotation. Rotating the locking plate 342 engages the semicircular end of the guide shaft 341 within the locking hole 322, with the smooth surface of the guide shaft 341 facing upward and the arcuate surface facing downward, preventing the knob selector 34 from moving. The smooth surface of the guide shaft 341 faces upwards and the arc surface faces downwards, so that the knob block 34 cannot move. The locking plate buckle 342 is L-shaped and has a raised baffle in both the locked and unlocked states for easy operation.

[0150] See Figure 11 In an optional embodiment, a clamping device 40 is provided on the base 30. The clamping device 40 includes a movable seat 41 for mounting the clamping silicone roller 17 and an adjustment rod 42 for controlling the radial movement of the movable seat 41. When the adjustment rod 42 moves to the right, the movable seat 41 drives the clamping silicone roller 17 away from the driving silicone roller 16, loosening the guide wire. The movable seat 41 is provided with a spring to cause it to move toward the driving silicone roller 16. When the adjustment rod 42 moves to the left, the movable seat 41 will gradually move closer to the driving silicone roller 16 until it compresses the guide wire.

[0151] See Figure 12 In an optional embodiment, a beveled groove 421 is provided at the bottom of the adjusting rod 42, and a guide post 411 is provided on the movable seat 41. The guide post 411 moves along the beveled groove 421. A sliding groove is provided on the base 30 only for the adjusting rod 42. When the adjusting rod 42 moves axially, the guide post 411 moves along the beveled groove 421, and the movable seat 41 moves radially, thereby achieving clamping and loosening of the guide wire.

[0152] See Figure 12 In an optional embodiment, the adjustment rod 42 is provided with a socket 422, to which a latch 43 is connected, with a spring positioned below the latch 43. The latch 43 extends upward and out of the adjustment rod 42. The adjustment rod 42 is provided with a hole for the latch 43, so that the adjustment rod 42 is not affected by the latch 43 during movement. The socket 422 has a right-angled trapezoidal cross-section, and the latch 43 corresponds to the socket 422, thereby limiting the position of the adjustment rod 42.

[0153] See Figure 10In an optional embodiment, a release protrusion 343 is provided on the knob 34. When the knob 34 is rotated to its lowest point, the release protrusion 343 presses down on the latch 43, disengaging it from the socket 422. When the knob 34 is in its highest position, the latch 43 engages the socket 422. The adjustment rod 42, via a spring, constantly presses the compression silicone roller 17 against the drive silicone roller 16. The latch 43, also via a spring, is constantly held upward, effectively locking the adjustment rod 42. When the latch 43 engages the adjustment rod 42, the distance between the compression silicone roller 17 and the drive silicone roller 16 is maximized. When the knob 34 is rotated to its lowest point, the release protrusion 343 presses down on the latch 43, disengaging it from the socket 422. The compression silicone roller 17 moves leftward, compressing the guide wire. As the knob 34 rotates upward, it drives the adjustment rod 42 radially, gradually increasing the distance between the compression silicone roller 17 and the drive silicone roller 16, allowing the guide wire to be removed.

[0154] See Figure 3 In an optional embodiment, a push block protrusion 423 is provided on the adjustment rod 42, and a push block 344 is provided on the knob 34. As the knob 34 rotates from its lowest point to its highest point, the push block 344 pushes the push block protrusion 423, moving the installation and compression silicone roller 17 away from the guidewire. When the knob 34 reaches its highest point, the distance between the compression silicone roller 17 and the drive silicone roller 16 is at its maximum. At this point, the latch 43 rises and engages the socket 422, preventing the adjustment rod 42 from moving axially.

[0155] The specific working method is:

[0156] In the initial state, the gate 35 is in the upper mounting groove 331 and is close to the second stopper 32. The latch 43 is stuck in the socket 422 of the adjustment rod 42, and the distance between the compression silicone roller 17 and the driving silicone roller 16 is at its maximum. The guide wire is placed in the lower mounting groove 332, and the knob 34 is turned clockwise. The gate 35 moves downward to press the guide wire downward. When the knob 34 is pressed to the lowest point, the guide wire is between the compression silicone roller 17 and the driving silicone roller 16. The release block 343 presses down the latch 43 to disengage it from the socket 422, and the compression silicone roller 17 moves to the left to compress the guide wire. Pulling the locking plate buckle 342 causes the semicircular end of the guide shaft 341 to be stuck in the lock hole 322, and the knob 34 is fixed. The rotation of the driving gear can drive the driving silicone roller 16 to rotate, thereby driving the guide wire for transportation. The delivery gear 12 is aligned with the opening 13 of the delivery body 10, and the spring presses against the clutch protrusion 241 to engage the groove 245. After the guidewire is inserted, the delivery gear 12 is rotated to drive the guidewire. When the guidewire reaches the designated position in the blood vessel, the delivery gear 12 stops rotating.

[0157] When the guide wire needs to be replaced, pull the locking plate buckle 342 to disengage the semicircular end of the guide shaft 341 from the lock hole 322, and then turn the knob 34 counterclockwise. The push block 344 of the knob 34 pushes the push block protrusion 423 to move the adjustment rod 42 to the right. The pressing silicone roller 17 releases the guide wire and the distance between it and the driving silicone roller 16 increases during the counterclockwise rotation of the knob 34. When the knob 34 is rotated to the highest point, the pin 43 moves upward under the action of the spring to clamp the adjustment rod 42. Lift the push rod 242 to separate the clutch protrusion 241 from the groove 245. At this time, rotate the conveying gear 12 again to keep the conveying body 10 and the opening 13 of the conveying gear 12 consistent, and remove the guide wire. The push rod 242 is no longer pushed up, and the spring presses the push rod 242 down. After reloading the medium from the opening 13 or replacing another guide wire, the conveying gear 12 is rotated. After rotating to a certain angle, the clutch protrusion 241 and the groove 245 will be re-engaged, and the guide wire will rotate together with the conveying gear 12 again.

[0158] See Figure 13 , an embodiment of the present invention provides an interventional surgical robot system, which uses the following toothed catheter, including a base 103 for installing the toothed catheter, the toothed catheter provides a channel for slender medical devices, and is used to assist tubular or long percutaneous interventional medical devices such as guide wires or catheters to enter the patient's body. A gear 104 is arranged on the base 103 and meshes with the rack 102. The gear 104 is controlled by a motor, and the flexible tube 101 is moved by the gear 104, and the automation is improved by the motor. The self-locking function can be achieved by the motor, and the flexible tube 101 will not move when it reaches the specified position. Because the flexible tube 101 needs to be connected to the patient end, the current existing technology cannot be controlled by a motor. After the flexible tube 101 is pulled to the specified position, a bump or other device is required to lock it.

[0159] See Figure 13 In an optional embodiment, a rigid channel 105 is provided on the base 103 for the flexible tube 101 to move. The channel's internal dimensions are larger than the tube's external dimensions, and a portion of the channel 105 is arcuate. This allows the flexible tube 101 to move without a specific trajectory and easily disengage from the gear 104. The rigid channel 105 defines the flexible tube's 101 movement position.

[0160] The tooth-type catheter is described in detail below through examples.

[0161] See Figure 14In an optional embodiment, a toothed catheter includes a flexible tube 1; a rack 2 is provided on the outer side of the flexible tube 1, and a notch 11 is provided at the distal end of the flexible tube 1. In the initial state, the flexible tube 1 is conveyed by a motor so that the notch 11 is at the distal end of the base 3, and the sheath and hemostatic valve connected to the patient's wound are fixed to the base, wherein the sheath enters the flexible tube 1 through the notch 11. When the flexible tube 1 moves toward the distal end, the sheath slowly enters the flexible tube 1 until the distal end of the flexible tube 1 is connected to the patient and stops. After reaching the designated position, the gear 4 driven by the motor has a self-locking effect and will not deviate, thereby improving safety.

[0162] In an optional embodiment, the flexible tube 1 is made of at least one of PDFE and PTFE, and has self-lubricating and bendable properties. Since the flexible tube 1 bends during use, it should also be bendable and have a certain elasticity so that the sheath tube will not be damaged therein.

[0163] See Figure 13 and Figure 14 In an optional embodiment, the flexible tube 1 is a hollow circular tube, and a connecting section 13 is provided at the distal end of the flexible tube 1. The connecting section 13 is connected to the connecting mechanism close to the human body end or is connected to the connecting mechanism at the human body end through a sheath clamp. The sheath clamp can use the patent number CN2014800566205, the patent name of which is the sheath clamp structure in the flexible track of the guide catheter control, and is connected to the human body by pulling the sheath clamp. Alternatively, it can also be connected to the human body through the patent number CN2020800137690, the patent name of which is the sheath clamp structure in the robotic catheter system adapter. As long as the connection between the connecting section 13 and the human body end can be achieved, it will be sufficient.

[0164] See Figure 14 In an optional embodiment, the flexible tube 1 and the rack 2 are integrally formed. The rack 2 is typically made of a hard material for ease of transport. If the rack 2 is present only on a section of the flexible tube 1, it can be integrally formed for ease of molding. Alternatively, the flexible tube 1 and the rack 2 are connected in a separate manner, with the rack 2 and the flexible tube 1 being manufactured separately and secured together using snaps or glue. It should be understood that all methods of connecting the rack 2 and the flexible tube 1 fall within the scope of the separate connection.

[0165] See Figure 14 and Figure 15In an optional embodiment, a long slit 12 is provided in the length direction of the flexible tube 1. The long slit 12 is connected to the notch 11, and the sheath enters the flexible tube 1 through the notch 11. The notch 11 gradually opens and becomes smaller along the proximal end. The maximum opening of the notch 11 is at 45°~120°, preferably 90°, to facilitate the entry of medical catheters such as guide wires and sheaths into the flexible tube 1. The long slit 12 should not be simply understood as an opening. The long slit 12 can be in two situations. The first is that the long slit 12 is an opening in the flexible tube 1, such as Figure 15 In the second case, when the opening of the flexible tube 1 is not subjected to external forces, the upper and lower surfaces of the long slit 12 are attached together due to gravity, without any opening. When the flexible tube 1 moves toward the distal end, the sheath tube separates the upper and lower surfaces of the long slit 12 through the notch 11 and slowly enters the flexible tube 1.

[0166] See Figure 14 In an optional embodiment, the elongated slit 12 and the rack 2 are correspondingly provided on both sides of the flexible tube 1. Existing flexible tubes 1 do not have a rack 2. When the flexible tube 1 is manually pulled, the flexible tube 1 rotates, causing the notch 11 and the elongated slit 12 to deflect, resulting in a non-optimal angle for the sheath to enter the flexible tube 1. This angle requires constant adjustment based on actual conditions, making it more complicated to use. However, in the present invention, after the flexible tube 1 is fixed by the rack 2, the position of the elongated slit 12 is fixed, i.e., the optimal angle for the sheath to enter the flexible tube 1. This angle does not change and does not require readjustment.

[0167] See Figure 50 In an optional embodiment, an extension arm mechanism includes a support mechanism 50, a support column 60 provided on the support mechanism 50, a bracket arm 70 rotatably arranged on the support column 60, a bracket middle arm 80 rotatably arranged on the bracket arm 70, and a bracket small arm 90 rotatably arranged on the bracket middle arm 80; the bracket middle arm 80 can be tilted in the height direction.

[0168] Specifically, the support mechanism 50 is fixed to the edge of a hospital bed on which a patient lies. A guide wire conveying and rotating device is connected to the support arm 90. The guide wire conveying and rotating device is adjusted to the optimal position by rotating the support arm 70, the support middle arm 80 and the support arm 90. The support middle arm 80 can be tilted in the height direction. This mechanism realizes adjustment in the XYZ axis direction, providing a more suitable angle for conveying the guide wire. The guide wire conveying and rotating device can be any one on the market, as long as it can realize the rotation and conveying functions of the guide wire.

[0169] See Figure 51In an optional embodiment, a slot 51 slidably connected to the bed is provided on the support mechanism 50 , and the support mechanism 50 is rotatably provided with a cam wrench 52 , and the support mechanism 50 is fixed by rotating the cam wrench 52 .

[0170] Specifically, the bedside of the hospital bed is designed to engage with the slot 51. After the support mechanism 50 is inserted into the bedside through the slot 51, a slight gap is left to facilitate the support mechanism 50's sliding along the bedside. By rotating the cam wrench 52 on the support mechanism 50, the support mechanism 50 can be fixed to the bedside. As the cam wrench 52 rotates, the distance from the bedside changes. When fixed, the cam wrench 52 presses against the bedside.

[0171] See Figure 51 In an optional embodiment, the cam wrench 52 is provided with a wrench arm 521, and a stopper 522 is provided on the wrench arm 521. Generally, the wrench arm 521 of the cam wrench 52 is parallel to the edge of the bed. In this fixed position, the wrench arm 521 is hidden in the groove of the support mechanism 50. This provides greater safety and prevents the wrench arm from being hit and causing the support mechanism 50 to slide. When the support mechanism 50 is in a slidable position, the wrench arm 52 forms an acute angle with the edge of the bed and protrudes from the support mechanism 50. The stopper 522 prevents the cam wrench 52 from excessive rotation, which could damage the cam wrench 52 and the edge of the bed.

[0172] See Figure 51 and Figure 52 In an optional embodiment, a clamping plate 53 connected to the cam wrench 52 is provided within the slot 51. The addition of the clamping plate 53 increases the contact area, preventing the cam surface of the cam wrench 52 from directly contacting the bedside. If the force-bearing area is too small, the contact area is easily damaged, and the fixing effect deteriorates over time. A guide shaft 54 is provided on the clamping plate 53. A spring is installed on the guide shaft 54 to push the clamping plate 53 toward the cam wrench 52. The spring always pushes the clamping plate 53 away from the bedside, preventing excessive friction during the sliding of the support mechanism 50. Four guide shafts 54 are distributed at the four corners of the clamping plate 53. A notch is also provided at the bottom of the support frame body for the clamping plate 53 to enter. A through-hole is provided on the side away from the slot 51 for connecting to the guide shaft 54, and the guide shaft 54 partially extends into the through-hole. After the spring is installed in the spring hole, one end of the guide shaft 54 is inserted into the spring hole and then inserted into the clamping plate 53 through the notch. The guide shaft 54 passes through the clamping plate 53 and then snaps into the through-hole. During disassembly, it is only necessary to insert a thin tube from the through hole to separate the guide shaft 54 from the clamping plate 53. This makes the support mechanism more convenient to assemble and disassemble.

[0173] See Figure 51In an optional embodiment, a support plate 55 is provided on the support mechanism 50. The device consisting of the support mechanism 50, the bracket upper arm 70, the bracket middle arm 80, and the bracket lower arm 90 is relatively large in length and width, which can easily cause the support mechanism 50 to tilt. Simply connecting it to the bed edge through the slot 51 will cause large wear. The support plate 55 can reduce the tilting force. Because the specifications of the operating table are the same, the height of the support plate 55 does not need to be adjusted under normal circumstances. However, in order to account for errors or tolerances in the manufacturing process, two waist holes are provided on the support plate 55. The waist holes and screws are used to fix the support plate 55 to the support mechanism 50, and fine-tuning can be achieved.

[0174] See Figure 55 In an optional embodiment, the bracket middle arm 80 includes a middle arm rotating seat 81 rotatably mounted on the bracket upper arm 70, a middle arm frame 82 rotatably mounted on the middle arm rotating seat 81, and a buffer cylinder 83. One end of the buffer cylinder 83 is rotatably mounted on the middle arm rotating seat 81, and the other end is rotatably mounted on the middle arm frame 82. The height adjustment of the middle arm frame 82 in the Z-axis direction is achieved by the extension and retraction of the buffer cylinder 83. The bracket middle arm 80 is provided with a shell to wrap the above-mentioned device. The bracket middle arm 80 is set to be adjustable in height for easy folding when not in use. On the other hand, it can make the height adjustment of the guide wire conveying device smaller and safer.

[0175] See Figure 55 In an optional embodiment, the middle arm frame 82 includes multiple parallel connecting rods 821. One end of each connecting rod 821 is rotatably connected to the middle arm rotating base 81, and the other end of each connecting rod 821 is rotatably connected to the connecting block 84. The buffer cylinder 83 is rotatably connected to one of the connecting rods 821. The damping friction plate ensures that the extension rod can rotate only when a certain amount of force is applied, and the mechanism does not shake after the force is released. The encoder provides feedback on the rotation angle, prompting the operator to adjust the position within a certain range.

[0176] Specifically, two connecting rods 821 are preferably provided, with one end of the buffer cylinder 83 being rotatably fixed to the lower connecting rod 821 and the other end being rotatably fixed to the upper connecting rod 821. When unloaded, the two connecting rods 821 are horizontal, and the buffer cylinder 83 is extended. When a force is applied, the connecting rod 821, which is away from the mid-arm pivot base 81, slowly descends, while the other end remains at a constant height but can rotate, causing the buffer cylinder 83 to slowly retract.

[0177] See Figure 55 In an optional embodiment, a lower stop pin 85 is provided on one connecting rod 821. The lower stop pin 85 is positioned on the upper connecting rod 821 at an adjustable angle, typically set at 45°. When the connecting rod 821 is lowered away from the middle arm rotating base 81, the lower stop pin 85 abuts against the middle arm rotating base 81, preventing the connecting rod from further descending.

[0178] See Figure 55 In an optional embodiment, the bracket arm 90 includes an adapter 91, an extension rod 92 detachably mounted on the adapter 91, and a connector 93. The adapter 91 is provided with a rotating shaft rotatably connected to the bracket middle arm 80. A connector 93 is provided at the end of the extension rod 92 away from the adapter 91, and the connector 93 is used to connect to the guide wire delivery and rotation device. The adapter 91 is provided with a fixing knob 94 for fixing the extension rod 92 to prevent the extension rod 92 from loosening during the rotation process. Interventional surgeries are all precision surgeries with good firmness and high safety performance. The extension rod 92 is inserted into the adapter 91, and the side is also fixed by a positioning pin.

[0179] See Figure 55 In an optional embodiment, a damping friction plate 95 is provided on the rotating shaft of adapter 91. An encoder 96 is provided at the end of the rotating shaft of adapter 91, distal from adapter 91. The rotating shaft of encoder 96 is fixed to the rotating shaft of adapter 91, and the two rotate together. Encoder 96 is a commercially available product that can monitor the rotation angle. The damping friction plate 95 ensures that the extension rod 92 can rotate only when a certain force is applied, and the mechanism does not shake after the force is released. Encoder 96 provides feedback on the rotation angle, prompting the operator to adjust the position appropriately within a certain range.

[0180] See Figure 54 In an optional embodiment, the bracket arm 70 includes a latch mechanism 71, a large brake tooth 74 disposed on the support column 60, and a middle brake tooth 75 disposed on the bracket middle arm 80. When the latch mechanism 71 abuts the large brake tooth 74, the bracket arm 70 cannot rotate. When the latch mechanism 71 abuts the middle brake tooth 75, the bracket middle arm 80 cannot rotate. The latch mechanism 71 does not need to abut both the large brake tooth 74 and the middle brake tooth 75 simultaneously; sequential braking should also be understood to fall within the scope of protection of the present invention.

[0181] See Figure 53 In an optional embodiment, the locking tongue mechanism 71 includes a first connecting plate 711, a first locking tongue 712 disposed on the first connecting plate 711, a second connecting plate 713, and a second locking tongue 714 disposed on the second connecting plate 713. When the first locking tongue 712 is connected to the large brake teeth 72, a braking effect is formed; when separated, the bracket arm 70 can rotate. When the second locking tongue 714 is connected to the middle brake teeth 75, a braking effect is formed; when separated, the bracket arm 80 can rotate. The first locking tongue 712 and the second locking tongue 714 both have teeth on their surfaces, which can engage with the large brake teeth 74 and the middle brake teeth 75, respectively, to prevent rotation.

[0182] See Figure 53In an optional embodiment, a control mechanism 72 is provided on the bolt mechanism 71 to enhance automated control. The control mechanism 72 includes a control motor 721, a double-ended screw 722 controlled by the control motor 721, and a first movable seat 723 and a second movable seat 724 mounted on the double-ended screw 722. The double-ended screw 722 and the control motor 721 are connected by a shaft sleeve. The first movable seat 723 is connected to the first connecting plate 711, and the second movable seat 724 is connected to the second connecting plate 712. Preferably, the first and second connecting plates 711 and 712 move simultaneously in opposite directions (increasing the distance between the first and second movable seats 723 and 724), allowing the first and second bolts 712 and 714 to simultaneously act as brakes to prevent rotation. The first and second connecting plates 711 and 712 simultaneously move relative to each other (decreasing the distance between the first and second movable seats 723 and 724), allowing the bolt mechanism 71, the large brake teeth 74, and the middle brake teeth 75 to rotate freely.

[0183] See Figure 54 In an optional embodiment, a manual release mechanism 73 is provided on the lock tongue mechanism 71, and the manual release mechanism 73 is used to deal with power outages or other emergency situations. The manual release mechanism 73 includes a release button 731, a power rod 732 connected to the release button 731, and a cam block 733 provided on the power rod 732. The cam block 733 is connected to the first connecting plate 711 and the second connecting plate 713. The power rod 732 is preferably a hexagonal power rod. The cam block 733 can be a non-circular cam block, preferably an elliptical one. When the release button 731 is turned manually, the first connecting plate 711 and the second connecting plate 712 move toward each other, releasing the brake.

[0184] Since the motor 721 itself has a self-locking function. After adding the manual release mechanism 73, the control mechanism needs to be improved accordingly. The control mechanism 72 includes a control motor 721, a double-headed screw 722 controlled by the control motor 721, and square nuts 727 symmetrically mounted on both sides of the double-headed screw 722. The two square nuts 727 are connected to the first movable seat 723 and the second movable seat 72 respectively. A concave ring 728 is provided in the middle of the double-headed screw 722. The concave ring 728 can be rotatably mounted on the concave ring mounting seat 729. The concave ring mounting seat 729 allows the double-headed screw 722 to only rotate around the axis and cannot move left and right along the axis. When the double-headed screw 722 rotates, the square nut 727 can move on the double-headed screw 722, and the convex ring mounting seat 729 increases the stability of the double-headed screw 722 in conveying. The double-headed screw 722 and the control motor 721 are connected by a shaft sleeve. The first movable seat 723 is connected to the first connecting plate 711, and the second movable seat 724 is connected to the second connecting plate 712. Springs (not shown) are connected to the first and second locking tongues 712, 714. The springs cause the first and second locking tongues 712, 714 to engage with the large brake teeth 74 and the middle brake teeth 75, respectively, to generate a braking effect.

[0185] To enhance the stability of the first and second connecting plates 711 and 712, the connecting plates are provided with movement slots, to which limit posts are connected. The limit posts secure the connecting plates, preventing them from bending downward or upward during movement. The movement slots also provide sufficient travel distance for the connecting plates.

[0186] See Figure 53 and Figure 56 In an optional embodiment, in order to improve safety and automation on the basis of the manual release mechanism 73, a micro switch is added to the control mechanism 72. The control mechanism 72 also includes a first micro switch 725 and a second micro switch 726 that are communicatively connected to the control motor 721. A contact is provided below the first micro switch 725 and the second micro switch 726. A trigger block is provided on the first movable seat 723 and the second movable seat 724, respectively, and a bevel structure is provided above the trigger block. When the first connecting plate 711 and the second connecting plate 712 move toward each other, the motor stops moving when the first movable seat 723 triggers the contact; when the first connecting plate 711 and the second connecting plate 712 move away from each other, the motor stops moving when the second movable seat 724 triggers the contact.

[0187] The specific working method is:

[0188] The initial state is locked. The teeth of the first and second locking tongues 712 and 714 engage with the large brake teeth 74 and middle brake teeth 75, respectively, preventing rotation. Pressing the release button (located on the operating arm of the guidewire delivery system) rotates the motor 721, causing the double-ended screw 722 to rotate on the concave ring mounting seat 729. A square nut 727 is located on the step between the first and second movable seats 723 and 724. This drives the first and second movable seats 723 and 724 toward each other. The first and second connecting plates 711 and 712 move toward each other, gradually separating the first and second locking tongues 712 and 714 from the large brake teeth 74 and middle brake teeth 75, respectively, releasing the brakes. The spring force gradually increases. After the brakes are released, the middle and upper arm joints can rotate freely. The motor 721 stops rotating when the trigger block on the first movable seat 723 triggers the contacts of the first microswitch 725.

[0189] When the release button is released, the motor 721 rotates in the opposite direction, rotating the double-ended screw 722 and causing the two square nuts 727 to move in opposite directions. The first and second connecting plates 711, 712 also move in opposite directions under the action of the spring force. When the trigger block of the second movable base 724 triggers the contacts of the second microswitch 726, the motor 721 stops rotating. At this point, the teeth of the first and second locking tongues 712, 714 engage with the large brake teeth 74 and the middle brake teeth 75, respectively, acting as brakes.

[0190] In an emergency or power outage, the locked state prevents the device from rotating freely. Turning the release button 73 overcomes the spring tension, causing the first and second connecting plates 711, 712 to move toward each other. The first and second locking tongues 712, 714 gradually separate from the large brake teeth 74 and middle brake teeth 75, respectively, releasing the brakes. Turning the release button 73 back to its original position causes the first and second connecting plates 711, 712 to move away from each other under the action of the spring, achieving the locked state. Example 2:

[0191] In order to improve the degree of automation, a clutch drive mechanism 26 is added on the basis of the first embodiment. The clutch drive mechanism 26 is described in detail below.

[0192] See Figure 7 In an optional embodiment, a clutch drive mechanism 26 is connected to the clutch mechanism 24. The clutch drive mechanism 26 includes a first motor 261, a crank 262 installed on the first motor 261, a slider 263 installed on the crank 262, a lifting groove 264 set on the slider 263, and a lifting push rod 265 that rises and falls along the lifting groove 264. The lifting push rod 265 controls the clutch of the clutch mechanism 24.

[0193] See Figure 7In an optional embodiment, the crank 262 is an L-shaped crank, and a movable slot 266 is provided on the side of the crank 262 close to the first motor 261. The L-shaped crank rotates along the rotating axis in the middle, and the movable slot 266 can be set to be open so that it will not disengage from the position during the forward and reverse rotation of the motor.

[0194] See Figure 7 In an optional embodiment, the first motor 261 is provided with a turntable 267, and a movable shaft 268 is eccentrically provided on the turntable 267, and the movable shaft 268 moves in the movable groove 266. The movable shaft 268 is adapted to the opening of the movable groove 266, and when the turntable 267 rotates, the crank 262 is driven to rotate.

[0195] See Figure 7 In an optional embodiment, a guide plate 269 is further provided between the slider 263 and the crank 262. The guide plate 269 is fixed to another large fixed plate (not shown). The large fixed plate is provided with a guide rail for the radial movement of the guide plate 269. The guide plate 269 can make the movement of the slider 263 more stable.

[0196] The specific working method is:

[0197] The first motor 261 drives the turntable 267 to rotate, and the movable shaft 268 rotates along with the turntable 267. The middle part of the L-shaped crank is rotatable. When the movable shaft 268 moves in the movable slot 266 of the crank 262, the crank 262 rotates. The other side of the crank 262 is connected to the guide plate 269, and the guide plate 269 is limited to move forward and backward. The slider 263 also moves forward and backward along with the guide plate 269, and there is a lifting slot 264 on the slider 263. During the movement of the slider 263, the lifting push rod 265 will be lifted and lowered along the lifting slot 264, thereby lifting or separating the push rod 242, which can replace the method of manually lifting the push rod 262.

[0198] In order to cope with the situation that the electric flexible tube 1 cannot meet the actual transportation requirements, a manual-automatic switching device for tube transportation is added between the motor and the gear 4, which can not only meet the requirements of manually pulling the tube to the specified position but also realize automatic control of the tube position. Figure 16 and Figure 17, including a flexible tube 101 and a catheter driving mechanism 1060 for driving the flexible tube 101 to move. The flexible tube 101 here is the flexible tube 1 of Example 1. The catheter driving mechanism 1060 includes an upper gear disc 61 and a lower gear disc 62 engaged with the upper gear disc 61. The lower gear disc 62 is driven to rotate by a second motor 63, and the lower gear disc 62 is driven to rise and fall by a third motor 64 through a gear disc lifting mechanism 65. When the upper gear disc 61 and the lower gear disc 62 are engaged and rotated, the flexible tube 101 is driven to move. When the upper gear disc 61 and the lower gear disc 62 are separated and rotated, the flexible tube 101 can be manually pulled. The upper gear disc 61 can drive the flexible tube 101 to move closer to or away from the patient in various ways.

[0199] See Figure 16 and Figure 18 In an optional embodiment, the lifting mechanism 65 includes a lifting rod 651 and an inclined slot 652 disposed on the lifting rod 651. The inclined slot 652 is connected to the lower gear plate 62. The end of the lifting rod 651 near the lower gear plate 62 is U-shaped, and the inclined slots 652 are symmetrically disposed on both sides of the lifting rod 651.

[0200] The lifting mechanism 65 also includes a lifting slider 655 that rises and falls along the inclined groove 652. An angular contact bearing is located within the lifting slider 655, and the lower gear plate 62 is mounted on the angular contact bearing. Shafts that mate with the inclined groove 652 are located at both ends of the lifting slider 655. Specifically, the opening of the inclined groove 652 and the shaft have equal diameters, and the shafts move along the inclined groove 652. The angular contact bearings are driven to rotate by the output shaft of the second motor 63. The angular contact bearings rotate together with the lower gear plate 62. Because the lower gear plate 62 rises and falls, it forms a sliding fit with the second motor 63.

[0201] In an optional embodiment, a thrust spring is provided on the lifting slider 655. In this case, the opening of the inclined groove 652 can be larger than the diameter of the shaft of the lifting slider 655. The meshing rotation between the gears will cause vibration, giving the shaft mobility in the up and down directions, thereby preventing damage to the lifting slider 655 or the lifting push rod 651.

[0202] See Figure 16 In an optional embodiment, the end of the lifting push rod 651 close to the third motor 64 is a rack 653, and the third motor 64 is provided with a scalloped disc 654 that meshes with the rack 653. The rotation of the third motor 64 drives the scalloped disc 654 to rotate, thereby driving the rack 653 to move. Example 3:

[0203] See Figure 19-Figure 30The present invention discloses a front-end snap-fit mechanism for a hemostatic valve, comprising an adapter 201 for mating with the hemostatic valve, a connector 202 detachably connected to the adapter 201, and a flexible tube 103 detachably connected to the connector 202. The adapter 201 includes a clamping groove 2011 for holding the hemostatic valve and a hollow portion 2012 communicating with one end of the clamping groove 2011. The adapter 201 has a connecting portion 2013 on one end, adjacent to the hollow portion 2012, for mating with the connector 202. The connecting portion 2013 includes a first through-hole 20131 extending therethrough and communicating with the hollow portion 2012. The hemostatic valve in this embodiment is an existing Y-type hemostatic valve. In this embodiment, an adapter 201 is provided, and a clamping groove 2011 is provided in the adapter. The main part of the hemostatic valve can be adapted to the clamping groove 2011 and clamped by the clamping groove 2011. The hollow part 2012 can be adapted to the adjustment position of the hemostatic valve. When the hemostatic valve is fixed on the adapter 201, the adjustment position of the hemostatic valve is just located in the hollow part 2012. The hemostatic valve in this embodiment is a rotary adjustment type, which is convenient for the operator to control the opening and closing of the hemostatic valve by rotating the adjustment position of the hemostatic valve through the hollow part 2012, which is more convenient to operate. The flexible tube 101 is hollow inside and is used to allow pipelines, guide wires and other equipment to pass through the hemostatic valve and protect the equipment. The flexible catheter 101 is also used to connect to the catheter robot. The connector 202 is used to connect the flexible tube 101 and the adapter 201.
