Description

[Technical field]

[0001] The present invention relates to the technical field of vascular intervention surgery, in particular to an auxiliary wire feeding mechanism for vascular intervention surgery. [Background Technology]

[0002] Vascular interventional surgery involves the insertion of specialized catheters, guidewires, and other precision instruments into the human body, guided by DSA (Digital Surgery) imaging technology, to diagnose and locally treat internal conditions. Compared to traditional surgery, vascular interventional surgery offers significant advantages, including minimal trauma, increased safety, precise and effective treatment, and rapid postoperative recovery.

[0003] The current traditional vascular interventional surgery is a double-edged sword. Although it has significant advantages, it also has obvious disadvantages, which are mainly reflected in the following: 1. Since doctors have to operate under medical imaging equipment, they need to be exposed to X-ray environment for a long time, which is very harmful to the body; 2. Although the entire surgical process is guided by images, instruments such as guidewires and catheters are small, and the doctor's operating skills are required to be high. [Summary of the invention]

[0004] The purpose of the present invention is to solve the above-mentioned deficiencies and provide an auxiliary wire feeding mechanism for vascular interventional surgery, which can quickly replace the guide wire and simulate the manual twisting operation to the greatest extent through the coordinated movement and rotation of the guide wire, thereby improving efficiency and strong operability.

[0005] In order to achieve the above-mentioned purpose, a vascular intervention surgery auxiliary wire feeding mechanism is designed, including a support base 1, a main base plate 6, a gear assembly, a rolling wheel assembly, a connecting rod assembly 13 and a sliding assembly 14. The main base plate 6 is rotatably mounted on the support base 1 through a first mounting shaft 10 and a second sleeve mounting shaft 15. A guide wire 25 is passed through the first mounting shaft 10 and the second sleeve mounting shaft 15; the rolling wheel assembly includes a driving roller 12 and a driven roller 11, and the guide wire 25 passes between the driving roller 12 and the driven roller 11. The connecting rod assembly 13 is fixed to the main base plate 6 through a mounting shaft, one end of the connecting rod assembly 13 is connected to the driven roller 11 through a sliding rotating shaft 23, and the other end of the connecting rod assembly 13 is connected to the sliding assembly 14. The sliding shaft of the sliding assembly 14 slides freely in the waist hole of the connecting rod assembly 13. The other end of 14 is slidably connected to the second sleeve mounting shaft 15 and moves axially along the second sleeve mounting shaft 15. The sliding assembly 14 drives the driven roller 11 to move upward or downward through the connecting rod assembly 13 to realize the separation or contact between the driven roller 11 and the driving roller 12; the gear assembly includes a wire feeding drive wheel 2, a wire feeding driven wheel, a rotating drive wheel 4 and a rotating driven wheel 5. The wire feeding drive wheel 2 drives the driving roller 12 to rotate through the wire feeding driven wheel under the drive of motor one, and the driving roller 12 drives the guide wire 25 to move forward or backward. The rotating drive wheel 4 is meshed with the rotating driven wheel 5. The rotating drive wheel 4 drives the rotating driven wheel 5 to rotate under the drive of motor two. The rotating driven wheel 5 is fixedly connected to the main base plate 6 through the fixed base 7, and drives the main base plate 6 to rotate, thereby driving the guide wire 25 to rotate.

[0006] Furthermore, the connecting rod assembly 13 includes a rotating arm 131, a rotating arm 2 132, a rotating shaft 133 and a spring 134. The rotating arm 131 and the rotating arm 2 132 are connected through the rotating shaft 133 and rotate around the rotating shaft 133. A spring 134 is connected between the rotating arm 131 and the rotating arm 2 132. The rotating arm 2 132 is connected to the sliding assembly 14, and the rotating arm 131 is connected to the driven roller 11.

[0007] Furthermore, a sliding limit block 22 is provided at the sliding rotation shaft 23 , and the rotating arm 131 drives the driven roller 11 to move linearly upward or downward through the sliding limit block 22 and the sliding rotation shaft 23 .

[0008] Furthermore, the sliding rotating shaft 23 is inserted into the waist-shaped hole on the main base plate 6 and moves up and down along the waist-shaped hole, thereby driving the driven roller 11 to move up and down.

[0009] Furthermore, the sliding assembly 14 is inserted into the slot of the second sleeve mounting shaft 15 and moves axially along the slot. When the sliding assembly 14 moves left or right in the slot, the driven roller 11 is driven to move upward or downward through the connecting rod assembly 13 to achieve separation or contact between the driven roller 11 and the driving roller 12.

[0010] Furthermore, the wire feeding driven wheel includes a wire feeding driven wheel A3, a main bevel gear 8, a slave bevel gear 9, a wire feeding driven wheel B17 and a wire feeding driven wheel C20. The wire feeding drive wheel 2 is meshed with the wire feeding driven wheel A3. The wire feeding driven wheel A3 and the main bevel gear 8 are fixed on the first mounting shaft 10. The rotation of the wire feeding driven wheel A3 drives the first mounting shaft 10 to rotate, thereby driving the main bevel gear 8 to rotate. The main bevel gear 8 is meshed with the slave bevel gear 9. The slave bevel gear 9 and the wire feeding driven wheel B17 are both fixed on the third mounting shaft 18. The movement of the slave bevel gear 9 drives the third mounting shaft 18 to move, and then drives the wire feeding driven wheel B17 to move. The wire feeding driven wheel B17 is meshed and connected with the wire feeding driven wheel C20. The wire feeding driven wheel C20 and the driving roller 12 are both fixed on the fifth mounting shaft 19. The driving roller 12 rotates under the drive of the wire feeding driven wheel C20, thereby driving the guide wire 25 to move forward or backward.

[0011] Furthermore, the wire feeding driven wheel also includes a wire feeding driven wheel D21 and a wire feeding driven wheel E24. The wire feeding driven wheel C20, the wire feeding driven wheel D21, and the driving roller 12 are fixed on the fifth mounting shaft 19 in sequence from bottom to top. The wire feeding driven wheel D21 is meshed and connected with the wire feeding driven wheel E24. The wire feeding driven wheel E24 and the driven roller 11 are all fixed on the sliding rotating shaft 23. The wire feeding driven wheel D21 drives the driven roller 11 to rotate in the opposite direction to the driving roller 12. The driving roller 12 and the driven roller 11 drive the guide wire 25 to move forward or backward.

[0012] Furthermore, the wire feeding driven wheel A3 and the main bevel gear 8 are relatively fixed to the first mounting shaft 10 through flat keys and snaps, the slave bevel gear 9 and the wire feeding driven wheel B17 are relatively fixed to the third mounting shaft 18 through flat keys and snaps, the wire feeding driven wheel C20, the wire feeding driven wheel D21 and the driving roller 12 are relatively fixed to the fifth mounting shaft 19 through flat keys and snaps, and the wire feeding driven wheel E24 and the driven roller 11 are relatively fixed to the sliding rotating shaft 23 through flat keys and snaps.

[0013] Furthermore, the front end of the first installation shaft 10 is designed to be semi-open to identify whether the guide wire 25 enters the first installation shaft 10 .

[0014] Furthermore, the sliding assembly 14 is fixed to the second sleeve mounting shaft 15 through magnetic contact, so that the wire feeding driven wheel will not jump slightly upward during the rotation process.

[0015] Compared to existing technologies, the present invention provides an auxiliary control mechanism suitable for vascular interventional surgery, capable of automatically controlling the forward, backward, and rotation of a guidewire, enabling independent or simultaneous coordinated control of the guidewire's forward, backward, and rotation, thus meeting the requirements of guidewire interventional surgery. The present invention has a simple structure, a small size, and can quickly replace guidewires. Furthermore, by coordinating the movement and rotation of the guidewire, it simulates manual twisting operations to the greatest extent possible, improving efficiency and enhancing operability. This solves the problems of traditional vascular interventional surgery, such as the long-term exposure of surgeons to X-ray environments, which poses significant health risks, and the high technical requirements for surgeons.

[Specific implementation method]

[0022] As shown in the accompanying drawings, the present invention provides an auxiliary wire feeding mechanism for vascular intervention surgery, including a support base 1, a main base plate 6, a gear assembly, a rolling wheel assembly, a connecting rod assembly 13 and a sliding assembly 14. The main base plate 6 is rotatably mounted on the support base 1 through a first mounting shaft 10 and a second sleeve mounting shaft 15. A guide wire 25 is passed through the first mounting shaft 10 and the second sleeve mounting shaft 15; the rolling wheel assembly includes a driving roller 12 and a driven roller 11, and the guide wire 25 passes between the driving roller 12 and the driven roller 11. The connecting rod assembly 13 is fixed to the main base plate 6 through the mounting shaft, one end of the connecting rod assembly 13 is connected to the driven roller 11 through a sliding rotating shaft 23, and the other end of the connecting rod assembly 13 is connected to the sliding assembly 14. The sliding shaft of the sliding assembly 14 slides freely in the waist hole of the connecting rod assembly 13. The other end is slidably connected to the second sleeve mounting shaft 15 and moves axially along the second sleeve mounting shaft 15. The sliding assembly 14 drives the driven roller 11 to move upward or downward through the connecting rod assembly 13 to achieve separation or contact between the driven roller 11 and the driving roller 12. The gear assembly includes a wire feeding drive wheel 2, a wire feeding driven wheel, a rotating drive wheel 4 and a rotating driven wheel 5. The wire feeding drive wheel 2 drives the driving roller 12 to rotate through the wire feeding driven wheel under the drive of the motor 1, and the driving roller 12 drives the guide wire 25 to move forward or backward. The rotating drive wheel 4 is meshed with the rotating driven wheel 5. The rotating drive wheel 4 drives the rotating driven wheel 5 to rotate under the drive of the motor 2. The rotating driven wheel 5 is fixedly connected to the main base plate 6 through the fixed base 7, and drives the main base plate 6 to rotate, thereby driving the guide wire 25 to rotate.

[0023] The sliding rotary shaft 23 is inserted into the waist-shaped hole on the main base plate 6 and moves up and down along the waist-shaped hole, thereby driving the driven roller 11 up and down. A sliding stopper 22 is provided at the sliding rotary shaft 23. Rotating arm 131 drives the driven roller 11 upward or downward linearly through the sliding stopper 22 and the sliding rotary shaft 23. The sliding assembly 14 is inserted into the slot of the second sleeve mounting shaft 15 and moves axially along the slot. When the sliding assembly 14 moves left or right within the slot, it drives the driven roller 11 upward or downward through the connecting rod assembly 13, thereby separating or contacting the driven roller 11 with the driving roller 12.

[0024] As attached Figure 4 As shown, the connecting rod assembly 13 includes a rotating arm 131, a rotating arm 2 132, a rotating shaft 133 and a spring 134. The rotating arm 131 and the rotating arm 2 132 are connected through the rotating shaft 133 and rotate around the rotating shaft 133. A spring 134 is connected between the rotating arm 131 and the rotating arm 2 132. The rotating arm 2 132 is connected to the sliding assembly 14, and the rotating arm 131 is connected to the driven roller 11.

[0025] The wire feeding driven wheel includes a wire feeding driven wheel A3, a main bevel gear 8, a slave bevel gear 9, a wire feeding driven wheel B17 and a wire feeding driven wheel C20. The wire feeding drive wheel 2 is meshed with the wire feeding driven wheel A3. The wire feeding driven wheel A3 and the main bevel gear 8 are fixed on the first mounting shaft 10. The rotation of the wire feeding driven wheel A3 drives the first mounting shaft 10 to rotate, thereby driving the main bevel gear 8 to rotate. The main bevel gear 8 is meshed with the slave bevel gear 9, and the slave bevel gear 8 is meshed with the slave bevel gear 9. The gear 9 and the wire feeding driven wheel B17 are both fixed on the third mounting shaft 18. The movement of the bevel gear 9 drives the third mounting shaft 18 to move, and then drives the wire feeding driven wheel B17 to move. The wire feeding driven wheel B17 is meshed and connected with the wire feeding driven wheel C20. The wire feeding driven wheel C20 and the driving roller 12 are both fixed on the fifth mounting shaft 19. The driving roller 12 rotates under the drive of the wire feeding driven wheel C20, thereby driving the guide wire 25 to move forward or backward. The wire feeding driven wheel also includes a wire feeding driven wheel D21 and a wire feeding driven wheel E24. The wire feeding driven wheel C20, the wire feeding driven wheel D21, and the driving roller 12 are fixed on the fifth mounting shaft 19 in sequence from bottom to top. The wire feeding driven wheel D21 is meshed with the wire feeding driven wheel E24. The wire feeding driven wheel E24 and the driven roller 11 are all fixed on the sliding rotating shaft 23. The wire feeding driven wheel D21 drives the driven roller 11 to rotate in the opposite direction to the driving roller 12. The driving roller 12 and the driven roller 11 drive the guide wire 25 to move forward or backward.

[0026] The present invention will be further described below in conjunction with specific embodiments:

[0027] The present invention is mainly composed of a support base, a main base plate, a gear assembly, a rolling wheel assembly, a connecting rod assembly and a sliding assembly, as shown in the attached Figure 1 The gear assembly mainly includes the wire feed drive wheel 2, the wire feed driven wheel A3, the main bevel gear 8, the slave bevel gear 9, the rotary drive wheel 4, the rotary driven wheel 5, the wire feed driven wheel B17; the wire feed driven wheel C20, the wire feed driven wheel D21, and the wire feed driven wheel E24; the rolling wheel assembly mainly includes the driving roller 12, the driven roller 11, the limiting sliding block 22, the sliding rotating shaft 23, and the third mounting shaft 18; and the sliding assembly mainly includes the sliding assembly 14 and the second sleeve mounting shaft 15.

[0028] Example 1: Quickly install and replace the guide wire. Figure 2 and attached Figure 3As shown. The main base plate 6 is mounted on the support base via the first mounting shaft 10 and the second sleeve mounting shaft 15. The roller is fixed to the main base plate 6 via the sliding rotating shaft 23, the third mounting shaft 18 and the sliding stop block 22. The connecting rod assembly 13 is fixed to the main base plate via its own mounting shaft and is connected to the driven roller 11 via the sliding rotating shaft 23. The rotating arm 131 and the rotating arm 2 132 on the connecting rod assembly 13 are connected via the rotating shaft 133 and the spring 134, and can rotate around the rotating shaft 133, as shown in the attached figure. Figure 4 As shown. The connecting rod assembly 13 and the sliding assembly 14 are connected through a waist hole, and the sliding shaft on the sliding assembly 14 can slide freely in the waist hole on the connecting rod assembly. Moving the sliding assembly 14 to the left drives the rotating arm 2 132 to rotate clockwise, and the spring 134 that is in tension is gradually compressed to drive the rotating arm 131 to rotate counterclockwise around the rotating shaft 133. The rotating arm 131 drives the driven roller 11 to move upward in a straight line through the sliding limit block 22 and the sliding rotating shaft 23. The sliding assembly 14 moves to contact and limit with the rotating shaft 133 and is fixed. At this time, the guide wire is inserted from the right end of the second sleeve mounting shaft 15, and enters and passes through the first mounting shaft 10 under the guidance of the sliding assembly 14. The front end of the first mounting shaft 10 is designed to be semi-open, and it can be clearly identified whether the guide wire has entered the first mounting shaft 10. After the guide wire successfully passes through the first mounting shaft 10, the sliding assembly 14 moves rightward, causing rotating arm 2 132 to rotate counterclockwise and stretch the spring. This stretches the compressed spring, driving rotating arm 1 131 clockwise. Rotating arm 1 131, via the sliding stop 22 and the sliding rotating shaft 23, drives the driven roller 11 in a linear downward motion. Simultaneously, the sliding rotating shaft 23 drives the wire feed driven roller in a linear downward motion, bringing it into contact with the wire feed driving roller. The sliding assembly 14 is secured to the third sleeve mounting shaft 23 through magnetic contact, preventing the wire feed driven roller from bouncing slightly upward during rotation.

[0029] Example 2: Wire feeding is achieved. Motor 1 drives the wire feed drive wheel 2 in clockwise rotation, which in turn drives the wire feed follower wheel A3 via a gear transmission. The wire feed follower wheel A3 and the main bevel gear 8 are relatively fixed to the first mounting shaft 10 via a flat key and a snap. Rotation of the wire feed follower wheel A3 drives the first mounting shaft 10, thereby driving the main bevel gear 8. The main bevel gear 8 drives the slave bevel gear 9 via a gear transmission. The slave bevel gear 9 and the wire feed follower wheel B17 are relatively fixed to the third mounting shaft 18 via a flat key and a snap. Movement of the slave bevel gear 9 drives movement of the third mounting shaft 18, which in turn drives movement of the wire feed follower wheel B17. The wire feed follower wheel B17 and the wire feed follower wheel C20 are meshed with gears. The wire feed follower wheel C20, the wire feed follower wheel D21, and the drive roller 12 are relatively fixed to the fifth mounting shaft 19 via a flat key and a snap, thereby driving the roller 12 to rotate counterclockwise. The wire feed follower D21 and wire feed follower E24 are driven by gear meshing. The wire feed follower E24 and driven roller 11 are fixed relative to the sliding rotating shaft via a flat key and a snap. The wire feed follower D21 drives the driven roller 11 clockwise. The counterclockwise rotation of the drive roller 12 and the clockwise movement of the driven roller 11 drive the guide wire forward. To retract the guide wire, a command is output to control Motor 1 to rotate the wire feed drive wheel 2 counterclockwise. Because the wire feed follower utilizes a gear transmission with the same gear ratio, the pair of rollers rotate at the same speed, preventing slippage during wire feeding.

[0030] Example 3, realize the rotation of the guide wire, as shown in the attached Figure 5 As shown, the rotating driven wheel 5 and the main base plate 6 are relatively fixed via a fixed base 7. Motor 2 drives the rotating driving wheel 4, which in turn drives the main base plate 6 to rotate. The rolling wheel assembly, sliding assembly, and second sleeve mounting shaft 15 for mounting the guidewire are all mounted on the main base plate 6. As the main base plate 6 rotates, the other accessories rotate, which in turn drives the guidewire.

[0031] Example 4, realize the coordinated work of wire feeding and rotation, as shown in the attached Figure 5 As shown. This invention differs from existing technologies by enabling coordinated wire feeding and rotation. The guide wire can rotate during forward and backward movement, simulating manual twisting operations to the greatest extent possible. Motors 1 and 2 are started simultaneously, and the drive wheel drives the driven wheels to rotate without interfering with each other.

[0032] The present invention is not limited to the above-mentioned embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
