Description

Technical Field

[0001] The present invention relates to the field of interventional consumables, and in particular to a metal wire shaping mechanism and a shaping needle shaping device. Background Art

[0002] The microcatheter in the interventional surgery needs to be shaped into the required shape with the help of a shaping needle before it is used in the interventional surgery. Usually, the shaping needle is a section of flexible metal wire. In the prior art, when shaping the shaping needle, most of the time, the clinician manually bends the shaping needle to shape it into the required shape, which is time-consuming, labor-intensive and has low precision. Summary of the invention

[0003] In view of the above problems, the present invention proposes a metal wire shaping mechanism and a shaping needle shaping device.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A metal wire shaping mechanism, comprising:

[0006] Mounting frame;

[0007] A first rotating member, rotatably mounted on the mounting frame;

[0008] A rotating swing arm is fixed on the first rotating member and rotates with the first rotating member;

[0009] A shaping seat is slidably mounted on the rotating swing arm, and a shaping top block is provided on the shaping seat;

[0010] A first rotating motor, used for driving the first rotating member to rotate;

[0011] A second rotating member is rotatably mounted on the mounting frame, the second rotating member is sleeved on the first rotating member in an outer sleeve or an inner sleeve, and the second rotating member is provided with an eccentric column;

[0012] A connecting piece, one end of which is rotatably mounted on the eccentric column, and the other end of which is rotatably mounted on the shaping seat;

[0013] The second rotating motor is used to drive the second rotating member to rotate. When the second rotating member rotates, it drives the shaping seat to move relative to the rotating swing arm through the connecting member.

[0014] The working principle of the metal wire shaping mechanism of the present application is as follows: when two rotating motors drive two rotating parts to rotate synchronously, the rotating swing arm and the shaping seat can rotate synchronously around the axis of the first rotating part. In actual use, they can rotate 360°, that is, the angular position of the shaping top block can be adjusted. When the second rotating part rotates relative to the first rotating part, the connecting part installed on the eccentric column can drive the shaping seat to move relative to the rotating swing arm, thereby controlling the shaping top block of the shaping seat to shape the metal wire.

[0015] The coaxial arrangement of the two rotating parts of the metal wire shaping mechanism of the present application has a compact structure and can shape the metal wire from all directions, thereby completing complex spatial structural modeling.

[0016] In one embodiment of the present invention, the first rotating member is a hollow member, and the second rotating member is rotatably sleeved on the first rotating member.

[0017] In one embodiment of the present invention, the rotating swing arm has a slide rail, the shaping seat is slidably mounted on the slide rail, and an elastic member is provided between the shaping seat and the rotating swing arm, the elastic member applies elastic force to the shaping seat to eliminate the gap during mechanical assembly. The elastic member is preferably a tension spring or a compression spring.

[0018] In one embodiment of the present invention, the wire shaping mechanism further includes a detection sensor fixed on the mounting frame, and the detection sensor is used to detect the zero position of the rotating swing arm.

[0019] In one embodiment of the present invention, the first rotating motor directly drives the first rotating member to rotate or drives the first rotating member to rotate through a transmission structure; the second rotating motor directly drives the second rotating member to rotate or drives the second rotating member to rotate through a transmission structure.

[0020] In actual use, the transmission structure can be a belt transmission assembly, a gear set or a worm gear structure.

[0021] The present application also discloses a shaping needle shaping device, comprising a frame and the above-mentioned metal wire shaping mechanism installed on the frame.

[0022] In one embodiment of the present invention, a wire conveying mechanism is further included, and the wire conveying mechanism includes:

[0023] A conveyor frame, mounted on the frame;

[0024] A rotating shaft, rotatably mounted on the conveying frame;

[0025] An active conveying wheel, coaxially fixed on the rotating shaft;

[0026] A conveying motor, used for driving the rotating shaft to rotate;

[0027] An adjusting shaft is rotatably mounted on the conveying frame, and one end of the adjusting shaft has an eccentric portion that is eccentrically arranged;

[0028] A driven conveying wheel, rotatably mounted on the eccentric portion, the driven conveying wheel being used to cooperate with the active conveying wheel to convey the metal wire;

[0029] A torsion spring, which is sleeved on the adjusting shaft, has one end matched with the adjusting shaft and the other end matched with the conveying frame, and is used to make the adjusting shaft have a rotation tendency to return to the initial position;

[0030] The adjusting sleeve is installed on the adjusting shaft through a one-way bearing. When the adjusting sleeve rotates in direction A, the adjusting sleeve can drive the adjusting shaft to rotate synchronously. When the adjusting sleeve rotates in direction B, the adjusting sleeve cannot drive the adjusting shaft to rotate synchronously. The directions A and B are opposite.

[0031] An adjusting motor, used for driving the adjusting sleeve to rotate;

[0032] The hollow shaping mouth is installed on the conveying frame, the inlet end of the shaping mouth is aligned with the area between the active conveying wheel and the driven conveying wheel, the active conveying wheel and the driven conveying wheel cooperate with each other to feed the metal wire into the shaping mouth, and the shaping top block on the shaping seat of the metal wire shaping mechanism is used to cooperate with the shaping mouth to shape the metal wire processed by the shaping mouth;

[0033] In the initial position, the active conveying wheel and the driven conveying wheel are in contact with each other. When the adjusting sleeve rotates in direction A, the adjusting shaft is driven to rotate, so that the axial position of the driven conveying wheel is deflected, and a gap for the metal wire to be inserted is formed between the driven conveying wheel and the active conveying wheel. When the adjusting sleeve rotates in direction B, under the action of the torsion spring, the adjusting shaft rotates toward the initial position, the axial position of the driven conveying wheel is deflected, and the gap between the active conveying wheel and the driven conveying wheel becomes smaller until the metal wire is clamped.

[0034] Working principle of the wire conveying mechanism: In the initial position, the active conveying wheel and the driven conveying wheel are in contact with each other. When the wire is to be input, the adjusting motor works to drive the adjusting sleeve to rotate around direction A. At this time, the one-way bearing is locked, and the adjusting sleeve drives the adjusting shaft to rotate synchronously, so that the axis position of the driven conveying wheel is deflected, and a gap for the wire to be inserted is formed between the driven conveying wheel and the active conveying wheel. When the wire is inserted into the gap, the adjusting motor is reset (that is, the adjusting sleeve rotates around direction B). At this time, under the action of the torsion spring, the adjusting shaft rotates to the initial position, and the axis position of the driven conveying wheel is deflected. The gap between the active conveying wheel and the driven conveying wheel becomes smaller until the wire is clamped. Under the action of the conveying motor, the active conveying wheel and the driven conveying wheel rotate to convey the wire forward to the shaping nozzle. Because of the existence of the torsion spring, the adjusting shaft of the wire conveying mechanism can rotate adaptively according to the force conditions, so that the axis position of the active conveying wheel can be adaptively adjusted to ensure reliable and stable wire conveying and effectively prevent jamming.

[0035] The metal wire conveying mechanism of the present application can make the metal wire very easily inserted between the active conveying wheel and the driven conveying wheel, and can convey the metal wire stably and reliably.

[0036] The axis position of the driven conveying wheel is the axis position of the eccentric part, and the A direction and the B direction are one of them being clockwise and the other being counterclockwise.

[0037] In actual application, one shaping method of this application is:

[0038] The motor is adjusted to work, so that a gap for the metal wire to be inserted is formed between the driven conveying wheel and the driving conveying wheel, and the metal wire is pushed into the gap between the driven conveying wheel and the driving conveying wheel; the motor is adjusted to reset, and the gap between the driving conveying wheel and the driven conveying wheel becomes smaller until the metal wire is clamped, and the conveying motor works, driving the driving conveying wheel and the driven conveying wheel to rotate, and the metal wire is fed into the shaping nozzle;

[0039] The metal wire is moved out of the shaping mouth, and the metal wire shaping mechanism works. The shaping top block first shapes an open circular ring of a set size on the metal wire, and then shapes a working section of a set shape.

[0040] This method can not only eliminate errors and ensure the shaping accuracy of the working section by shaping a ring, but the ring is also convenient for doctors and nurses to hold later.

[0041] In one embodiment of the present invention, the axis of the adjusting shaft is parallel to the axis of the rotating shaft.

[0042] In one embodiment of the present invention, the driven conveying wheel is rotatably mounted on the eccentric portion via a rotating bearing.

[0043] In one embodiment of the present invention, the conveying motor directly drives the rotating shaft to rotate or drives the rotating shaft to rotate through a transmission structure; the adjusting motor directly drives the adjusting sleeve to rotate or drives the adjusting sleeve to rotate through a transmission structure.

[0044] The beneficial effects of the present invention are as follows: the coaxial arrangement of the two rotating parts of the metal wire shaping mechanism of the present application has a compact structure, and the metal wire can be shaped from all directions, thereby completing complex spatial structure modeling.

DETAILED DESCRIPTION

[0058] The present invention is described in detail below in conjunction with the accompanying drawings.

[0059] like Figure 1 , 2 , 3 and 4, a wire shaping mechanism 40, comprising:

[0060] Mounting frame 41;

[0061] A first rotating member 42 is rotatably mounted on the mounting frame 41;

[0062] The rotating swing arm 43 is fixed on the first rotating member 42 and rotates along with the first rotating member 42;

[0063] A shaping seat 44 is slidably mounted on the rotating swing arm 43, and a shaping top block 441 is provided on the shaping seat 44;

[0064] A first rotating motor 45 is used to drive the first rotating member 42 to rotate;

[0065] A second rotating member 46 is rotatably mounted on the mounting frame 41. The second rotating member 46 is sleeved on the first rotating member 42. The second rotating member 46 has an eccentric column 461.

[0066] A connecting member 47, one end of which is rotatably mounted on the eccentric column 461, and the other end of which is rotatably mounted on the shaping seat 44;

[0067] The second rotating motor 48 is used to drive the second rotating member 46 to rotate. When the second rotating member 46 rotates, it drives the shaping seat 44 to move relative to the rotating swing arm 43 through the connecting member 47.

[0068] The working principle of the metal wire shaping mechanism 40 of the present application is as follows: when two rotating motors drive two rotating parts to rotate synchronously, the rotating swing arm 43 and the shaping seat 44 can rotate synchronously around the axis of the first rotating part 42, and can rotate 360° in actual use, that is, the angular position of the shaping top block 441 can be adjusted. When the second rotating part 46 rotates relative to the first rotating part 42, the connecting part 47 installed on the eccentric column 461 can drive the shaping seat 44 to move relative to the rotating swing arm 43, so that the shaping top block 441 of the shaping seat 44 can be controlled to shape the metal wire.

[0069] The metal wire shaping mechanism 40 of the present application has two coaxial rotating parts, which has a compact structure and can shape the metal wire from all directions, thereby completing complex spatial structural modeling.

[0070] like Figure 4 As shown, in this embodiment, the first rotating member 42 is a hollow member, and the second rotating member 46 is rotatably sleeved on the first rotating member 42 .

[0071] like Figure 1 and 3 As shown, in this embodiment, the rotating swing arm 43 has a slide rail 431, and the shaping seat 44 is slidably mounted on the slide rail 431. An elastic member 432 is also provided between the shaping seat 44 and the rotating swing arm 43. The elastic member 432 applies an elastic force to the shaping seat 44 to eliminate the gap in the mechanical assembly process. That is, if the elastic member 432 is not provided, the shaping seat 44 may cause a slight shake due to the existence of the assembly gap. By providing the elastic member 432, an elastic force can always be applied to the shaping seat, thereby preventing shaking, that is, eliminating the gap.

[0072] The elastic member 432 is preferably a tension spring or a compression spring. Figure 3 As shown, the elastic member 432 is a compression spring.

[0073] like Figure 3 As shown, in this embodiment, the wire shaping mechanism 40 further includes a detection sensor 49 fixed on the mounting frame 41 , and the detection sensor 49 is used to detect the zero position of the rotating swing arm 43 .

[0074] In actual use, the first rotating motor 45 directly drives the first rotating member 42 to rotate or drives the first rotating member 42 to rotate through a transmission structure; the second rotating motor 48 directly drives the second rotating member 46 to rotate or drives the second rotating member 46 to rotate through a transmission structure. The transmission structure can be a belt transmission assembly, a gear set, or a worm gear. In this embodiment, the transmission structure is a belt transmission assembly.

[0075] like Figure 5As shown, this embodiment also discloses a shaping needle shaping device, including a frame 1 and a metal wire shaping mechanism 40 and a metal wire conveying mechanism 20 of this embodiment installed on the frame 1. Figure 6 , 7 , 8 and 9, the wire feeding mechanism 20 comprises:

[0076] A conveyor frame 21 is mounted on the frame 1;

[0077] A rotating shaft 22 is rotatably mounted on the conveying frame 21;

[0078] The active conveying wheel 23 is coaxially fixed on the rotating shaft 22;

[0079] A conveying motor 24, used for driving the rotating shaft 22 to rotate;

[0080] The adjusting shaft 25 is rotatably mounted on the conveying frame 21. The axis of the adjusting shaft 25 is parallel to the axis of the rotating shaft 22. One end of the adjusting shaft 25 has an eccentric portion 251 which is eccentrically arranged.

[0081] A driven conveying wheel 26 is rotatably mounted on the eccentric portion 251, and the driven conveying wheel 26 is used to cooperate with the active conveying wheel 23 to convey the metal wire;

[0082] A torsion spring 27 is sleeved on the adjustment shaft 25, one end of which is matched with the adjustment shaft 25, and the other end of which is matched with the conveying frame 21. The torsion spring 27 is used to make the adjustment shaft 25 have a rotation tendency to return to the initial position;

[0083] The adjusting sleeve 28 is installed on the adjusting shaft 25 through the one-way bearing 29. When the adjusting sleeve 28 rotates around the A direction, the adjusting sleeve 28 can drive the adjusting shaft 25 to rotate synchronously. When the adjusting sleeve 28 rotates around the B direction, the adjusting sleeve 28 cannot drive the adjusting shaft 25 to rotate synchronously. The A direction is opposite to the B direction.

[0084] An adjusting motor 30, used for driving the adjusting sleeve 28 to rotate;

[0085] The hollow shaping mouth 31 is installed on the conveying frame 21. The inlet end of the shaping mouth 31 is aligned with the area between the active conveying wheel 23 and the driven conveying wheel 26. The active conveying wheel 23 and the driven conveying wheel 26 cooperate with each other to feed the metal wire into the shaping mouth 31. The shaping top block 441 on the shaping seat 44 of the metal wire shaping mechanism 40 is used to cooperate with the shaping mouth 31 to shape the metal wire processed by the shaping mouth 31.

[0086] In the initial position, the active conveying wheel 23 and the driven conveying wheel 26 are in contact with each other. When the adjusting sleeve 28 rotates around the A direction, the adjusting shaft 25 is driven to rotate, so that the axial position of the driven conveying wheel 26 is deflected, and a gap for the metal wire to be inserted is formed between the driven conveying wheel 26 and the active conveying wheel 23. When the adjusting sleeve 28 rotates around the B direction, under the action of the torsion spring 27, the adjusting shaft 25 rotates toward the initial position, the axial position of the driven conveying wheel 26 is deflected, and the gap between the active conveying wheel 23 and the driven conveying wheel 26 becomes smaller until the metal wire is clamped.

[0087] The working principle of the wire conveying mechanism 20 is as follows: in the initial position, the active conveying wheel 23 and the driven conveying wheel 26 are in contact and cooperate with each other. When the metal wire is to be input, the adjusting motor 30 works to drive the adjusting sleeve 28 to rotate around the A direction. At this time, the one-way bearing 29 is locked, and the adjusting sleeve 28 drives the adjusting shaft 25 to rotate synchronously, so that the axial position of the driven conveying wheel 26 is deflected, and a gap for the metal wire to be inserted is formed between the driven conveying wheel 26 and the active conveying wheel 23. When the metal wire is inserted into the gap, the adjusting motor 30 is reset (that is, the adjusting sleeve 28 rotates around the B direction). At this time, under the action of the torsion spring 27, the adjusting shaft 25 rotates to the initial position, and the axial position of the driven conveying wheel 26 is deflected. The gap between the active conveying wheel 23 and the driven conveying wheel 26 becomes smaller until the metal wire is clamped. Under the action of the conveying motor 24, the active conveying wheel 23 and the driven conveying wheel 26 rotate to convey the metal wire forward to the shaping mouth 31. Due to the presence of the torsion spring 27, the adjusting shaft 25 of the wire conveying mechanism 20 can adaptively rotate according to the force conditions, thereby adaptively adjusting the axial position of the active conveying wheel 23 to ensure reliable and stable conveying of the wire and effectively prevent jamming.

[0088] The metal wire conveying mechanism 20 of the present application can make the metal wire very easily inserted between the active conveying wheel 23 and the driven conveying wheel 26, and can convey the metal wire stably and reliably.

[0089] The axis position of the driven conveying wheel 26 is the axis position of the eccentric portion 251 , and the directions A and B are clockwise and counterclockwise, respectively.

[0090] In actual application, one shaping method of this application is:

[0091] The regulating motor 30 works to form a gap between the driven conveying wheel 26 and the driving conveying wheel 23 for inserting the metal wire, and the metal wire is pushed into the gap between the driven conveying wheel 26 and the driving conveying wheel 23; the regulating motor 30 is reset, and the gap between the driving conveying wheel 23 and the driven conveying wheel 26 becomes smaller until the metal wire is clamped, and the conveying motor 24 works to drive the driving conveying wheel 23 and the driven conveying wheel 26 to rotate, and the metal wire is fed into the shaping nozzle 31;

[0092] The metal wire is removed from the shaping mouth 31, and the metal wire shaping mechanism 40 starts to work. The shaping top block 441 first shapes an open circular ring of a set size on the metal wire, and then shapes a working section of a set shape.

[0093] This method can not only eliminate errors and ensure the shaping accuracy of the working section by shaping a ring, but the ring is also convenient for doctors and nurses to hold later.

[0094] like Fig. 9 As shown, in this embodiment, the driven conveying wheel 26 is rotatably mounted on the eccentric portion 251 via a rotating bearing.

[0095] In this embodiment, the conveying motor 24 directly drives the rotating shaft 22 to rotate or drives the rotating shaft 22 to rotate through a transmission structure; the adjusting motor 30 directly drives the adjusting sleeve 28 to rotate or drives the adjusting sleeve 28 to rotate through a transmission structure.

[0096] like Fig. 9 As shown, in this embodiment, at least one of the active conveying wheel 23 and the driven conveying wheel 26 has an annular groove 231. The annular groove 231 can cooperate with the metal wire and can better convey the metal wire.

[0097] like Figure 6 and 9 As shown, the conveying frame 21 has a feeding chute 211, one end of which is aligned with the area between the active conveying wheel 23 and the driven conveying wheel 26. The wire conveying mechanism 20 also includes a box ejecting gear 4 and a gear drive motor 5 for driving the box ejecting gear 4 to rotate, and the tooth portion 4a of the box ejecting gear 4 is located in the feeding chute 211.

[0098] The shaping needle shaping device of this embodiment also includes a wire feeding box 10 for installing the wire. The wire feeding box 10 can be slidably inserted into the feeding chute 211. The wire feeding box 10 is used to feed the wire between the active conveying wheel 23 and the driven conveying wheel 26.

[0099] like Fig.10 and 11 As shown, in this embodiment, the wire feeding box 10 includes:

[0100] A long strip-shaped feeding box body 11, the feeding box body 11 has a receiving space 111, and a guide channel 112 is provided at the front end of the feeding box body 11, and the guide channel 112 is connected to the receiving space 111;

[0101] The ejector 12 is slidably mounted on the feed box body 11 and has a protrusion 121 located in the accommodating space 111. When the ejector 12 drives the protrusion 121 to move toward the side close to the front end of the feed box body 11, the metal wire located in the accommodating space 111 can be pushed forward through the guide channel 112.

[0102] The feeding box body 11 can accommodate metal wires. When in use, the metal wires can be pushed forward by pushing the ejection member 12. Due to the limiting effect of the guide channel 112, the metal wires can be moved out stably without bending, and the metal wires can be reliably fed into the corresponding mechanism.

[0103] In actual use, after the metal wire is loaded into the feeding box body 11 , a portion of the metal wire is located in the accommodating space 111 , and the other portion is located in the guide channel 112 .

[0104] like Fig.11 As shown, in this embodiment, the feeding box body 11 has a strip hole 113, and the ejection member 12 has a push block 122 that passes through the strip hole 113. The push block 122 is provided to facilitate manual pushing of the ejection member 12, and the provision of the strip hole 113 allows the push block 122 to move without interference.

[0105] like Fig.10 As shown, in this embodiment, the outer side wall of the feeding box body 11 has a rack 114 arranged along the length direction of the feeding box body 11, and the rack 114 is used to cooperate with the box ejection gear 4.

[0106] When in use, insert the wire feeding box 10 into the feeding chute 211, and then push the ejector 12 to push the wire further forward from the feeding box body 11, and feed it between the active conveying wheel 23 and the driven conveying wheel 26. After the wire feeding box 10 is completed, there is no need to take it out manually. The wire feeding box 10 can be automatically ejected from the feeding chute 211 through the cooperation of the box ejection gear 4 and the rack 114 of the wire feeding box 10.

[0107] like Figure 6 and 11 As shown, the shaping needle shaping device in this embodiment also includes a stopper 8 arranged on the feeding chute 211, and the feeding box body 11 has a positioning surface 115. The stopper 8 cooperates with the positioning surface 115 to limit the maximum distance that the feeding box body 11 slides into the feeding chute 211.

[0108] The above description is only a preferred embodiment of the present invention, and does not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention and the drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the present invention.

When the adjusting sleeve rotates around the direction A, the adjusting shaft is driven to rotate, so that the axial position of the driven conveying wheel is deflected, and a gap for the metal wire to be inserted is formed between the driven conveying wheel and the active conveying wheel. When the adjusting sleeve rotates around the direction B, under the action of the torsion spring, the adjusting shaft rotates to the initial position, the axial position of the driven conveying wheel is deflected, and the gap between the active conveying wheel and the driven conveying wheel becomes smaller until the metal wire is clamped.
