Compared with the prior art, the system of the present application performs interventional surgery by remotely controlling the robot, and realizes remote control of the advancement, retreat and rotation of the guide wire and guide catheter during surgery, and can simultaneously control the advancement and retreat of the balloon catheter or stent and catheter. The non-contact motor system divides the terminal execution system into an upper execution housing and a lower drive housing, the execution housing is used to accommodate the modular assembly of each disposable interventional equipment, and the drive housing is used to accommodate the power supply members and control members that cannot be disinfected and washed. A space is formed between the execution housing and the drive housing to arrange a sterile cloth, which prevents contamination of the members of the drive housing that cannot be disinfected and washed, and does not affect the normal operation of the vascular intervention robot. The positioner assembly is provided with a first sensor and a first detection point for axially positioning the sun gear, and a second sensor and a second detection point for radially positioning the sun gear, thereby effectively determining the position and angle of the sun gear and facilitating the control of the advance / retreat distance and rotation angle of the interventional equipment. The driving members, such as the motor and the transmission rod, are moved into the drive housing to reduce the space occupied in the implementation housing, so that more interventional equipment can be mounted in the drive housing, the operation space is larger, and the drive housing is easily cleaned. Furthermore, the surgical robot arm positioner is provided to ensure that the surgical robot arm is fixed and immobile when the implementation housing is assembled to the drive housing (i.e., the implementation housing is located on the drive housing), so that the movement of the surgical robot arm is prevented from adversely affecting the operation, and the safety of the robot is improved. The present invention is a combination of various types of interventional surgery consumables into one system, and the mechanical damping is mainly realized by the meshing between gears or the transmission by the transmission rod. The present invention realizes the robotization of interventional surgery and prevents the surgeon from suffering from injuries caused by exposure to large amounts of radiation during surgery.The robotization of interventional surgery improves the stability and accuracy of surgery, and furthermore, remote control by the surgeon reduces the risk of cross-infection between medical staff and patients. Based on this, the present invention has been completed.
[0185] The present invention will be further described below with reference to specific examples. It should be understood that these examples are only used to explain the present invention and do not limit the scope of the present invention.

[0187] Example 1 The surgical robot system of this embodiment is as shown in Figures 1a to 16. The surgical robot system includes a remote microcomputer control terminal 56, a surgical robot arm 55, and a terminal execution system 54. The terminal execution system 54 includes a guidewire control module, a balloon / stent control module, and a guide catheter control module, and can control the advancement, retraction, and rotation of the guidewire, as well as the advancement, retraction, and rotation of the balloon catheter or stent catheter, and the guide catheter. The guidewire control module includes a rotation assembly and a feed assembly.
[0188] The rotation assembly is used to control the rotation of the guidewire and includes a rotation wheel set and Rotating wheel set The gear 15 includes a rotating shaft 8 concentrically connected to the rotating shaft 8, a planetary gear 16 fitted around the rotating shaft 8 and slidable relative to the rotating shaft, and a sun gear 15 meshing with the planetary gear 16. The sun gear 15 is provided with a wire groove 14 for receiving a guide wire. The wire groove becomes gradually smaller from the outside to the inside along the radius so as to receive guide wires of different diameters. The wire groove 14 opens at the bottom of the valley between the teeth of the sun gear 15 and does not affect the meshing of the sun gear 15 with other gears. The wire groove 14 opens from the bottom of the valley between the teeth of the sun gear 15 to the center of the sun gear 15, and the wire groove 14 is for receiving the guide wire and ensuring the coaxiality of the rotation of the guide wire. The rotating shaft 8 is a hexagonal shaft.
[0189] The feed assembly is for controlling the forward or backward movement of the guide wire, and includes a feed wheel set 5, a transmission screw rod 2 concentrically connected to the gears of the feed wheel set 5, and a fixed housing 10 for supporting a sun gear 15. The sun gear 15 and the planetary gear 16 are both arranged in the internal space of the fixed housing 10, and move with the forward and backward movement of the fixed housing 10. The near end of the transmission screw rod 2 is connected and fixed to the running bevel gear 11 of the feed wheel set 5, and the near end of the rotating shaft 8 is connected and fixed to the rotating wheel set. The far end of the transmission screw rod 2 and the far end of the rotating shaft are both fixed to a fixed plate 24 at the far end via bearings. The fixed plate 24 is provided with a wire groove 14 that allows the guide wire to be received. The feed wheel set 5 is composed of two sets of running bevel gears 11. The feed wheel set 5 further includes an interlocking belt 12 for connecting the running bevel gears 11, and the interlocking belt 12 realizes the interlocking of the running bevel gears 11 of the feed wheel set 5. The fixed housing 10 is a hollow housing, and the sun gear 15 is disposed in the hollow internal space of the fixed housing 10. The fixed housing 10 is further provided with a radial opening for receiving a guide wire. The sun gear 15 and the fixed housing 10 are disposed concentrically.
[0190] The rotating wheel set and the feed wheel set 5 are both located on the same cross section. Both the rotating wheel set and the feed wheel set 5 are driven by a motor, and the rotation of the rotating wheel set rotates the rotating shaft 8 concentrically connected thereto, which in turn rotates the planetary gear 16, which in turn rotates the sun gear 15 by meshing action.
[0191] The rotation of the gear of the feed wheel set 5 rotates the transmission screw rod 2, and the fixed housing 10 is screw-connected to the transmission screw rod 2 and moves forward or backward with the rotation of the transmission screw rod 2.
[0192] The fixed housing 10 is provided with at least two fixed gears 13, which are meshed with the sun gear 15 to fix the sun gear 15. The fixed gears 13 are symmetrically installed on the upper part of the fixed housing 10 and are used to provide symmetrical support for the sun gear 15 and clamp the rotating shaft 8.
[0193] Here, the combination of the sun gear 15, the fixed gear 13, the planetary gears 16 and the fixed housing 10 is referred to as a gear housing set 3.
[0194] The guidewire control module includes a locking device for locking the guidewire, and the locking device is fixed to the sun gear 15. The locking device includes a lock control assembly, a movable member 21, and a fixed member 22. The fixed member 22 is fixed to the sun gear 15 and is arranged parallel to one side of the wire groove 14. The movable member 21 is installed opposite to the fixed member 22 and is arranged parallel to the other side of the wire groove 14. The lock control assembly is connected to the movable member 21 to control the positional relationship of the movable member 21 with respect to the fixed member 22. The lock control assembly controls the movable member 21 to move away from the fixed member 22. That is, the wire groove 14 forms a passage and can receive the guidewire. The lock control assembly controls the movable member 21 to reach the fixed member 22 and clamps the guidewire received in the wire groove 14. The locking device can be driven by electricity or air pressure.
[0195] The lock control assembly includes a pressing key 17, an interlocking rod 18, a spring 19, and a position limiting block 20. The spring 19 and the position limiting block 20 are installed in the internal space of the movable member 21, and the position limiting block 20 is fixed and does not move. The spring 19 is located between the position limiting block 20 and the side wall of the movable member 21, and one end of the interlocking rod 18 is connected to the pressing key 17 and the other end is connected to the movable member 21. When the lock device is in the unlocked state, pressing the pressing key 17 moves the interlocking rod 18 outward, thereby moving the movable member 21 radially outward, and the movable member 21 moves away from the fixed member 22. At this time, the spring 19 is in a compressed state. When the lock device is in the locked state, if the pressing control on the pressing key 17 is released, the movable member 21 moves radially inward due to the elastic action of the spring 19 and reaches the fixed member 22, and the pressing key 17 returns to its initial position.
[0196] The contact surfaces of the movable member 21 and the fixed member 22 are tooth-like clamping surfaces, which provide a greater clamping force to the guidewire.
[0197] The guidewire control module includes a guidewire support rod, which is installed between the sun gear 15 and the fixed plate 24. The guidewire support rod is slidable along the axial direction of the guidewire.
[0198] The guide wire support rod comprises a support frame 25 and pulleys 9 on both sides. The support frame 25 has wire grooves corresponding to the wire grooves of the sun gear 15 and the fixed plate 24. In use, the guide wire is received in the wire groove, and the pulleys 9 on both sides can move within the corresponding slide grooves on both side walls.
[0199] The slide groove starts from both side wall surfaces corresponding to the intermediate portion between the sun gear 15 and the fixed plate 24 and ends at both side wall surfaces corresponding to the fixed plate 24 .
[0200] The slide groove starts at both side wall surfaces corresponding to the sun gear 15 and ends at both side wall surfaces corresponding to the fixed plate 24. Stoppers are provided in the portion of the slide groove corresponding to the intermediate portion between the sun gear 15 and the fixed plate 24, and the stoppers are used to prevent the intermediate support member from sliding.
[0201] A magnet is provided on the guide wire support rod, and another magnet is provided on the wheel housing cover corresponding to the magnet, and the two magnets are in a mutually attractive relationship. In the operation of conveying the guide wire, the guide wire support rod is initially located at the midpoint between the sun gear 15 and the fixed plate 24, and the guide wire is placed in the wire groove. As the fixed housing 10 moves to the far end along the transmission screw rod 2, an attractive effect occurs between the two magnets, and the guide wire support rod continues to move together with the fixed housing 10 toward the far end. In the operation of returning the guide wire, the guide wire support rod is returned together with the fixed housing 10 toward the near end. When the guide wire support rod is returned to the midpoint between the sun gear 15 and the fixed plate 24, the guide wire support rod is fixed without being returned any further due to the blocking effect of the stopper or the wall of the slide groove, and the fixed housing 10 continues to return.
[0202] A pair of guidewire transmission wheels 1 for supporting and transporting the guidewire at the distal end are provided at a position 5 to 15 mm away (center distance) from the fixed plate 24 on the distal end of the fixed plate 24. The joint of the guidewire transmission wheels 1 corresponds to the wire groove 14 of the fixed plate 24. The guidewire is disposed between the guidewire transmission wheels 1, and is transported by friction between the guidewire transmission wheels 1.

The transmission wheel set 7 includes two pairs of friction wheel sets and a gear set connected below the friction wheel sets, and the gears are connected to a motor. In use, the motor drives the gears to rotate, which rotates the upper friction wheel set, and thus the balloon catheter or stent catheter clamped by the friction wheel set advances or retreats. The transmission wheel set 7 is also equipped with a transmission wheel set lock switch 23, which is used to control the distance between a pair of transmission wheel sets 7 and further control the locking status of the transmission wheel sets 7.

Y-assembly body 6 is fixedly connected to rack 27, and drive gear 26 is connected to a motor, and drive gear 26 rotates interlocking gear 28 by meshing between the gears, which in turn mesh with rack 27, respectively. In use, the motor rotates drive gear 26, and the meshing action moves rack 27 forward or backward, thereby moving Y-assembly body 6 forward or backward.

The front end of the Y-type valve (Y-type assembly 6) is connected to the guide catheter, and the forward and backward movement of the guide catheter is controlled by controlling the forward and backward movement of the Y-type valve. The transmission wheel set 7 clamps the balloon catheter or stent balloon catheter and moves it forward or backward. The rotating wheel set and feed wheel set 5 control the rotation, forward or backward movement of the guide wire. The rotation, forward or backward movement of all components can be achieved by the surgeon operating and controlling a terminal controller outside the operating room. Terminal execution system 54 can be connected via wired, wireless (WiFi, Bluetooth, etc.) or internet Remote microcomputer control terminal 56 The operation terminal is a computer and includes a joystick and a tablet computer, and the surgeon adjusts parameters displayed on the tablet computer to adjust the distance of advancement or retraction of the guide wire and the rotation angle of the guide wire, adjust the distance of advancement or retraction of the guide catheter, and adjust the distance of advancement or retraction of the balloon catheter or stent catheter, and then operates the joystick to control the advancement, retraction, or rotation of the guide wire, operate the joystick to control the advancement or retraction of the balloon catheter or stent catheter, and operate the joystick to control the advancement, retraction, or rotation of the guide catheter.

The execution housing 32 is equipped with mechanical members for carrying, returning, and rotating the interventional equipment, and the drive housing 33 is equipped with an electric assembly for providing driving power to the mechanical members. The execution housing 32 and the drive housing 33 are connected to each other via a magnetic coupling pair 35, and a space layer 53 having a gap of 2 to 20 mm is formed between the execution housing 32 and the drive housing 33.
[0217] Distal execution system 54 includes a guidewire control module 45 for controlling the advancement, retraction, and rotation of the guidewire. Guidewire control module 45 includes a rotation assembly for controlling the rotation of the guidewire, and a feed assembly for controlling the advancement or retraction of the guidewire.
[0218] The rotating assembly includes a rotating wheel set 34, a rotating shaft 8 concentrically connected to the rotating wheel set 34, planetary gears fitted on the rotating shaft 8 and slidable relative to the rotating shaft 8, and a sun gear 15 meshing with the planetary gear.

[0220] Both the rotating wheel set 34 and the feed wheel set 5 are connected to and driven by the motor in the drive housing 33 via the magnetic coupling pair 35 described above.
[0221] Guidewire control module 45 further includes a locking device 36 for locking the guidewire, where locking device 36 is fixed to sun gear 15. Locking device 36 includes a lock control assembly, a movable member, and a fixed member, where the fixed member is fixed to sun gear 15 and arranged parallel to one side of wire groove 14, and the movable member is disposed opposite to the fixed member and arranged parallel to the other side of wire groove 14. The lock control assembly is connected to the movable member to control the positional relationship of the movable member to the fixed member.
[0222] The lock control assembly controls the movable member to move away from the fixed member, i.e., the wire groove 14 forms a passageway and can receive the guide wire, and further controls the movable member to reach the fixed member and clamp the guide wire received in the wire groove 14. The lock device 36 may be an electrically operated clamp structure or a pneumatic clamp structure driven by air pressure.
[0223] The lock control assembly includes a pressing key, an interlocking rod, a spring, and a position limiting block, the spring and the position limiting block are installed in the inner space of the movable member, and the position limiting block is fixed and does not move. The spring is located between the position limiting block and the side wall of the movable member, and one end of the interlocking rod is connected to the pressing key and the other end is connected to the movable member.
[0224] When the locking device 36 is in the unlocked state, pressing the pressing key moves the interlocking rod outward, which moves the movable member radially outward and away from the fixed member. At this time, the spring is in a compressed state. When the locking device 36 is in the locked state, releasing the pressing control on the pressing key moves the movable member radially inward due to the elastic action of the spring until it reaches the fixed member, and the pressing key returns to its initial position.
[0225] In order to provide a larger clamping force for the guidewire, the contact surface between the movable member and the fixed member is preferably a toothed clamping surface, and more preferably the toothed clamping surface is covered with a silica gel coating layer.
[0226] The positioner assembly used in the vascular intervention robot in this embodiment includes a guidewire control module positioner and a surgical robot arm positioner.
[0227] The guidewire control module positioner is used to position the guidewire control module 45 of the terminal execution system 54. The guidewire control module positioner includes a first detection point 37 installed at the bottom of the fixed housing 10, a first sensor 38 for detecting the first detection point 37, a second detection point 39 installed at one end of the sun gear 15 opposite to the wire groove 14, and a second sensor 40 for detecting the second detection point 39, and the first sensor 38 and the second sensor 40 are both installed at the bottom of the terminal execution system 54. The first sensor 38 and the second sensor 40 are both installed in the drive housing 33, and the first detection point 37 and the second detection point 39 are both installed in the execution housing 32. In the execution housing 32, a sensor opening 41 is provided at a position corresponding to the first sensor 38 and the second sensor 40 of the drive housing 33, and the first sensor 38 and the second sensor 40 detect the first detection point 37 and the second detection point 39 through the sensor opening 41, respectively. Alternatively, the sensor opening 41 may not be provided in the bottom wall of the executive housing 32, and the portions corresponding to the first sensor 38 and the second sensor 40 may be made transparent, or the entire bottom wall of the executive housing 32 may be made transparent. Both the first sensor 38 and the second sensor 40 in this embodiment are laser sensors.
[0228] In operation, when the first sensor 38 detects a first detection point 37 on the bottom of the fixed housing 10 (the first detection point 37 is directly above the first sensor 38), a signal is sent to the remote microcomputer control terminal 56 (e.g., a computer) to perform axial positioning for the guidewire control module 45. When the second sensor 40 detects a second detection point 39 located at an end of the locking device 36 opposite the wire groove 14 (the second detection point 39 is directly above the second sensor 40), a signal is sent to the remote microcomputer control terminal 56 to perform radial positioning for the guidewire control module 45.
[0229] The purpose of the axial positioning for the interventional equipment control module 45 is to facilitate calculation of the distance advanced by the interventional equipment and to set the target distal and proximal positions for the interventional equipment. The purpose of the radial positioning for the interventional equipment control module 45 is to facilitate calculation of the rotation angle of the interventional equipment and to set the target angle for said interventional equipment.
[0230] The positioner assembly further includes a surgical robot arm positioner, which is mounted on the drive housing 33 of the distal execution system 54 and is used to detect whether the execution housing 32 is located on the drive housing 33. When the surgical robot arm positioner detects that the execution housing 32 is on the drive housing 33, the surgical robot arm 55 is fixed and does not move. When the surgical robot arm positioner detects that the execution housing 32 is removed from the drive housing 33, the surgical robot arm 55 is free to move. The surgical robot arm positioner is an infrared sensor.
[0231] In order to prevent contamination of the components inside the drive housing 33 during surgery, it is preferable that a sterile cloth is placed between the execution housing 32 and the drive housing 33. The area of the sterile cloth that corresponds to the sensor is transparent.
[0232] In the guidewire control module 45 (i.e., the guidewire moving / rotating module), one end of the guidewire is clamped by the sun gear 15, and the other end is placed on the case cylinder of the guidewire control module 45. At this time, as shown in Figs. 26-27, one guidewire support slide rod 42 is arranged between the sun gear 15 and the case cylinder, and the guidewire support slide rod 42 has a semicircular structure, and two L-shaped brackets extend from the bottom of the semicircle, and are received in slide rail grooves on both sides of the case cylinder, so that the guidewire support slide rod 42 can move back and forth within the slide rail groove. The guidewire support slide rod 42 has a receiving groove 43 with a width of 0.1-5 mm opened from the top to near the center of the circle, and the height of the bottom of the receiving groove 43 is on the same horizontal line as the center of the sun gear 15 and the height of the guidewire arrangement point on the case cylinder of the guidewire control module 45. A circular through hole 44 is opened on each side of the semicircular structure of the guidewire support slide rod 42, and the diameter of the circular through hole 44 is 0.1 to 3 mm. Two flexible tubes are inserted into both ends of the circular through hole 44, and after passing through the circular through hole 44, the flexible tubes abut against each other in the receiving groove 43, thereby preventing the guidewire from warping or rolling, and ultimately from coming off the receiving groove 43 of the guidewire support slide rod 42.
[0233] A first magnet 50 is provided on the guide wire support slide rod 42, and a second magnet 50 is provided on the fixed housing 10 corresponding to this, and the first magnet 50 and the second magnet 50 are attracted to each other.
[0234] In the operation of conveying the guide wire, the guide wire support slide rod 42 is located at the intermediate portion between the sun gear 15 and the case cylinder, and the guide wire is placed in the receiving groove 43, and as the fixed housing 10 moves toward the proximal end along the transmission screw rod 2, an attraction action occurs between the second magnet 50 and the first magnet 50, and the guide wire support slide rod 42 continues to move together with the fixed housing 10 toward the proximal end. In the operation of returning the guide wire, the guide wire support slide rod 42 is returned toward the distal end together with the fixed housing 10, and when it is returned to the intermediate position between the sun gear 15 and the case cylinder, the guide wire support slide rod 42 is fixed without being returned any further due to the blocking action of the stopper or the wall of the slide rail groove, and the fixed housing 10 may be returned continuously.
[0235] As shown in Figs. 40 to 42, the Y-type assembly body 6 preferably further includes a guide catheter support member for supporting the guide catheter 71 extending from the Y-type valve. This guide catheter support member includes a sliding sleeve 68, a sliding sleeve handle 69, and a sliding sleeve track 70. The sliding sleeve track 70 for accommodating the sliding sleeve 68 is provided in the Y-type valve, and the sliding sleeve 68 can slide in the sliding sleeve track 70 to extend from the Y-type valve or retract into the Y-type valve. The sliding sleeve handle 69 is provided at the distal end (the end farther from the operator) of the sliding sleeve 68, and the operator can control the advancement of the guide catheter 71 by moving the sliding sleeve handle 69. In one embodiment, the sliding sleeve handle 69 is a protrusion located at the distal end of the sliding sleeve 68. A long slit is provided in the upper part of the sliding sleeve 68 in the axial direction, and the guide catheter 71 can enter the sliding sleeve 68 through the long slit in the axial direction and be accommodated therein.
[0236] When the guide catheter 71 extends too far from the Y-valve, the sliding sleeve 68 is pulled out of the sliding sleeve track 70 by pulling the sliding sleeve handle 69 to support the extended guide catheter 71. When this is no longer necessary, the sliding sleeve 68 is pushed back into the Y-valve.
[0237] Example 2 The terminal execution system 54 of this embodiment is similar to that of embodiment 1, but differs in that, as shown in Figures 28 to 32, the terminal execution system 54 of this embodiment further includes a guidewire central fixator 46, and a guidewire locker 47 is used instead of the locking device 36 of embodiment 1.
[0238] The guidewire center fixator 46 is installed on the sun gear 15 and has an arrangement similar to that of the receiving groove 43 and the pair of circular through holes 44 in the above-mentioned guidewire support slide rod 42, and is installed corresponding to the wire groove 14 and used to fix the guidewire that has passed through the wire groove 14. The guidewire center fixator 46 has a cylindrical structure and is fixedly connected to the same center as the sun gear 15. Like the sun gear 15, a groove is opened up to the center and corresponds to the wire groove 14, and circular through holes 44 are opened on both sides of the groove, each of which is used for inserting a soft material. The guidewire is received by the sun gear 15 and the limiting groove, and the soft material holds the guidewire in place.
[0239] The guidewire locker 47 is detachably installed on the side of the proximal end of the sun gear 15 and is used to lock the guidewire. The guidewire locker 47 is divided into two parts, an upper part 48 and a lower part 49, which are fitted together so that the lid is closed by the attraction of a magnet 50 (note that the upper part 48 and the lower part 49 can be fitted together so that the lid is closed by other methods such as engagement, fitting, adhesion, frictional fixing, etc., but are not limited to these). The bottom surface of the upper part 48 and the top surface of the lower part 26 are each provided with a semicircular groove, and when the upper part 48 and the lower part 49 are fitted together so that the lid is closed, the two semicircular grooves combine to form a guidewire hole 51, and a guidewire lock knob 52 is further provided at the tail end.
[0240] When operating the guidewire locker 47, the top cover of the guidewire locker 47 is removed, the guidewire is passed through the guidewire lock knob 52, and the guidewire is placed in the guidewire hole 51. Upper part 48 and lower part 49 The guidewire lock knob 52 is rotated to secure the guidewire locker 47 to the sun gear 15. In this manner, the guidewire can rotate as the sun gear 15 rotates.
[0241] In another embodiment, the guidewire locker 47 is a stud and nut structure, where the guidewire is sandwiched between the lower edge of the stud and the upper edge of the nut, and the stud and nut are tightened to clamp the guidewire. One of the stud or nut is fixed to the sun gear 15.
[0242] In another embodiment, the guidewire locker 47 is a clip structure that is attached to the sun gear 15, the clip can be loosened to place the guidewire, and the clip can be tightened to clamp the guidewire.
[0243] Example 3 The distal execution system 54 of this embodiment is similar to that of the first embodiment, except that, as shown in FIGS. 33 to 36, the rack and pinion set for the guide catheter of this embodiment is Spar This is achieved by gear 57 and is positioned by a magnetic member set.
[0244] The robot is used for interventional treatment and comprises a remote microcomputer control terminal, a surgical positioning robot arm, and a distal execution system, the distal execution system being fixed to the end of the surgical positioning robot arm and moving together with the surgical positioning robot arm, and the remote microcomputer control terminal controlling the movement of the surgical positioning robot arm and the internal movement of the distal execution system.
[0245] The distal execution system includes a guide catheter control module in the interventional device for controlling the advancement or retraction of the guide catheter.

[0246] The distal end port of the Y-valve 63 is connected to a guide catheter, and a guidewire is inserted into the proximal end port. The guidewire passes through the Y-valve 63 and into the guide catheter, passing through the internal space of the guide catheter to reach the surgical site.
[0247] The rack and pinion set consists of a rack frame and Spar It includes a gear 57, a movable magnetic member 61 attached to the rack frame, and a fixed magnetic member 62 that interacts with the movable magnetic member 61. A Y-type valve 63 is fixed to the rack frame and moves with the movement of the rack frame. Spar The gear 57 is meshed with a straight rack on the rack frame. The fixed magnetic member 62 is fixed to the execution housing of the end execution system.
[0248] The rack frame includes a first toothed edge 58, a second straight edge 59, and a third connecting edge 60. The first toothed edge 58 includes: SparA straight rack is provided to mesh with the gear 57, and the second straight edge 59 and the first tooth edge 58 are arranged in parallel and opposite to each other. The third connecting edge 60 connects the first tooth edge 58 and the second straight edge 59 together to form a semi-encircling structure. Spar Gear 57 is located within the semi-encircling structure. Spar One end of the gear 57 meshes with the straight rack of the first tooth edge 58, Spar The other end of the gear 57 abuts against the second straight edge 59. The movable magnetic member 61 is fixed to the third connecting edge 60.
[0249] The rack frame is prevented from sliding freely by the interaction of the movable magnetic member 61 with the fixed magnetic member 62 which is fixed to the housing of the end execution system.
[0250] During the operation, the drive unit Spar The gear 57 is driven to rotate. Spar Due to the meshing relationship between the gear 57 and the rack frame, the rack frame moves forward while overcoming the force of the fixed magnetic member 62, thereby moving the Y-type valve 63 forward and avoiding loss of precision due to unnecessary relative displacement between each member.
[0251] The driving device is a non-contact motor system. The non-contact motor system includes a motor, a first magnetic coupling connected to the motor and driven by the motor, a second magnetic coupling installed corresponding to the first magnetic coupling, and a transmission gear set connected to the second magnetic coupling, the first magnetic coupling and the second magnetic coupling facing each other coaxially, and the distance between the first magnetic coupling and the second magnetic coupling is 2 to 20 mm.

[0253] Example 5 As shown in Figures 38 and 39, the end execution system 54 of this embodiment is similar to that of the fourth embodiment, but the difference is that the transmission screw rod 2 and the motor 29 that rotates the transmission screw rod 2 in this embodiment are moved into the drive housing 33, and the first magnetic coupling 30 and the second magnetic coupling 31 form a vertically combined relationship. In addition, the motor 29 that rotates the planetary gear 16 is also moved into the drive housing 33, and the rotating shaft 8 is removed, and instead, the motor 29 that rotates the planetary gear 16 is attached to the intermediate connection member 72 (for example, via the tray 64 in Figure 38), and advances in synchronization with the gear housing set 3 as the transmission screw rod 2 rotates. Correspondingly, in the execution housing 32, the planetary gears 16 are fixed within the fixed housing 10 via an optical axis 65, the planetary gears 16 can rotate relative to the optical axis 65, and one of the planetary gears 16 (for example, the planetary gear located in the lower right corner of FIG. 38) meshes with the second magnetic coupling 31 via a worm 66, a transmission gear (set), etc.
[0254] When the motor 29 rotates the transmission screw rod 2, the gear housing set 3 is advanced via one intermediate connecting member 72 and a magnetic coupling pair, and the motor 29, which rotates the planetary gear 16 in conjunction with the rotation of the transmission screw rod 2, is advanced in synchronization with the gear housing set 3, and the motor 29, which rotates the planetary gear 16, rotates the planetary gear 16 in the fixed housing 10 via another magnetic coupling pair, thereby rotating the sun gear 15 that meshes with the planetary gear 16.
[0255] A support guide rail 67 is preferably provided below the motor 29 that rotates the planetary gear 16 to support the motor 29 that rotates the planetary gear 16 and to guide its travel. In a preferred example, the support guide rail 67 includes a guide rail installed in the drive housing 33 and a roller attached below the motor 29 that rotates the planetary gear 16, and the roller can slide on the guide rail, thereby fulfilling the role of support and guide. In another preferred example, the support guide rail 67 is a guide bar with a smooth surface installed in the drive housing 33, and the upper surface of the guide bar slides against (or is supported and guided by magnetic levitation, etc.) the lower surface of the motor 29 that drives the planetary gear 16 to provide support and guide. The above-mentioned embodiment of the support guide rail 67 is not meant to be limiting, and various other embodiments may be used as long as they can guide and support the motor 29 that rotates the planetary gear 16.
