[0071] like Figures 1 to 13 As shown, it is a preferred embodiment provided by the present invention.

[0072] The guidewire operator 100 provided in this embodiment is used to operate a guidewire assembly 200, which includes an inner guidewire 201 and a guidewire jacket 202 covering the outer periphery of the inner guidewire 201, wherein the guidewire operator 100 includes an outer sleeve 10, a guidewire jacket locking sleeve 20, an outer guidewire locking member 30, an inner sleeve member 40, an inner guidewire locking sleeve 50 and an inner guidewire locking member 60; the end surface of the guidewire jacket locking sleeve 20 is formed with a guidewire receiving port 21 for the guidewire jacket 202 to pass through, and the guidewire jacket locking sleeve 20 is sleeved on the end of the outer sleeve 10; the outer guidewire locking member 30 has an outer guidewire through groove 31 for the guidewire jacket 202 to slide in and out, and the outer guidewire locking member 30 is arranged in the outer sleeve 10 and can move along the axial direction of the outer sleeve 10; the outer guidewire locking member 30 and the guidewire jacket locking member 20 are connected to each other. A gripping structure 10a is provided between the sleeves 20 for clamping and releasing the guide wire sleeve 202; the inner sleeve component 40 is connected to the outer guide wire locking member 30 and has a guide wire receiving groove 41 for the inner guide wire 201 to pass through and a concave cavity 42 connected to the guide wire receiving groove 41, and the inner sleeve component 40 is movably arranged in the outer sleeve 10; the inner guide wire locking sleeve 50 includes an inner locking sleeve portion 51 slidably arranged in the concave cavity 42; the inner guide wire locking member 60 has an inner guide wire through groove 61 for the inner guide wire 201 to slide in and out, and a guide wire through groove 52 corresponding to the inner guide wire through groove 61 is provided on the inner guide wire locking sleeve 50, and the inner guide wire locking member 60 is slidably arranged in the inner sleeve component 40; a locking structure 10b for clamping and releasing the inner guide wire 201 is provided between the inner guide wire locking member 60 and the inner guide wire locking sleeve 50.

[0073] The above-mentioned guide wire operator 100 adopts a guide wire sleeve locking sleeve 20, an outer guide wire locking member 30, an inner guide wire locking sleeve 50 and an inner guide wire locking member 60. A gripping structure 10a for clamping and loosening the guide wire outer sleeve 202 is arranged between the outer guide wire locking member 30 and the guide wire sleeve locking sleeve 20, and a locking structure 10b for clamping and loosening the inner guide wire 201 is arranged between the inner guide wire locking member 60 and the inner guide wire locking sleeve 50. The guide wire outer sleeve and the inner guide wire can be clamped and loosened at the same time, so that the operator can operate the guide wire outer sleeve and the inner guide wire at the same time, which is convenient for operation and use, improves the safety and operability of interventional surgery, shortens the operation time, and reduces the physical and mental consumption of doctors.

[0074] See also Figures 1 to 13 The guidewire operator 100 of this embodiment is used to perform operations such as clamping and fixing the inner and outer layers of the guidewire assembly 200, moving the inner layer forward and backward, and rotating the outer layer. The guidewire assembly 200 includes a guidewire jacket 202 located on the outer layer and an inner guidewire 201 arranged in the guidewire jacket 202. The guidewire jacket 202 and the inner guidewire 201 are both made of metal material, preferably stainless steel. In particular, the guidewire jacket 202 is wound with a spiral structure, so that it has the function of free deformation.

[0075] See also Figures 1 to 13 The guide wire operator 100 of this embodiment includes an outer sleeve 10, a guide wire sleeve locking sleeve 20, an outer guide wire locking member 30, an inner sleeve member 40, an inner guide wire locking sleeve 50, an inner guide wire locking member 60 and a push rod 71, and the above components are all but not limited to plastic parts.

[0076] See also Figures 1 to 13 The outer sleeve 10 is roughly in the shape of a hollow cylinder, and includes a front end (an end for the guide wire assembly 200 to enter and exit) and a rear end. The guide wire sleeve locking sleeve 20 is installed on the front end of the outer sleeve 10. The push rod 71 is built into the outer sleeve 10 and extends from the rear end of the outer sleeve 10. The rear end of the outer sleeve 10 is connected with a sleeve end cover 72. The sleeve end cover 72 and the outer sleeve 10 can be connected and fixed by all existing fixing methods such as threads and welding.

[0077] See also Figures 1 to 13 The guide wire sleeve locking sleeve 20 can be fixedly sleeved on the front end of the outer sleeve 10, or can be movably installed on the front end of the outer sleeve 10. The end surface of the guide wire sleeve locking sleeve 20 is formed with a guide wire receiving port 21 for the guide wire sleeve 202 to pass through.

[0078] See also Figures 1 to 13The outer guide wire lock 30 is arranged in the outer sleeve 10 and can move along the axial direction of the outer sleeve 10. The outer guide wire lock 30 has an outer guide wire through groove 31 for the guide wire sleeve 202 to slide in and out. A gripping structure 10a is arranged between the outer guide wire lock 30 and the guide wire sleeve locking sleeve 20, which is used to clamp and fix the guide wire sleeve 202 when the outer guide wire lock 30 moves toward the guide wire sleeve locking sleeve 20, and release the guide wire sleeve 202 when the outer guide wire lock 30 is separated from the guide wire sleeve locking sleeve 20. It is easy to understand that the guide wire assembly 200 enters the product from the front end of the guide wire operator 100, that is, the guide wire receiving port 21 of the guide wire sleeve locking sleeve 20, and sequentially passes through the outer guide wire through groove 31 of the outer guide wire locking member 30, pushing the outer guide wire locking member 30 to move forward, and the gripping structure 10a clamps and fixes the guide wire jacket 202 between the outer guide wire locking member 30 and the guide wire sleeve locking sleeve 20, thereby achieving the fixation of the guide wire jacket 202 by the guide wire operator 100; by pushing the outer guide wire locking member 30 to move backward, the outer guide wire locking member 30 is separated from the guide wire sleeve locking sleeve 20, and the guide wire jacket 202 is loosened at the same time, so that the gripping and loosening of the guide wire jacket 202 is convenient and can be achieved with one hand operation, thereby simplifying the operation difficulty and improving the convenience of use.

[0079] See also Figures 1 to 13 The gripping structure 10a includes at least two elastic claws 32 formed on the end of the outer wire lock 30 and extending along the axial direction of the outer sleeve 10 and a clamping cavity 22 formed on the wire sleeve lock sleeve 20; the clamping cavity 22 is used for inserting at least two elastic claws 32, and after the at least two elastic claws 32 are inserted, the elastic claws 32 are pressed against the elastic claws 32 in the radial direction of the outer sleeve 10 so that the elastic claws 32 move inward and compress the wire sleeve 202, the clamping cavity 22 is connected with the wire receiving port 21, and at least two elastic claws 32 are arranged at intervals along the circumference of the outer wire lock 30. In this embodiment, the number of the elastic claws 32 is but not limited to two, the elastic claws 32 extend forward from the front end of the outer wire lock 30 along the axial direction of the outer sleeve 10, the two elastic claws 32 have a predetermined deformation gap, are connected with the outer wire through groove 31 and allow the wire sleeve 202 to pass through, and the cross-sectional area of ​​the deformation gap is greater than the cross-sectional area of ​​the wire sleeve 202. It can be understood that when the outer guide wire locking member 30 moves forward, the front end of the elastic claw 32 moves inward in the radial direction of the outer sleeve 10 and clamps the guide wire sleeve 202 through the squeezing of the cavity wall of the clamping cavity 22; when moving backward, the squeezing force applied to the elastic claw 32 is eliminated, and the front end of the elastic claw 32 elastically resets outward to loosen the guide wire sleeve 202.

[0080] In another embodiment, the elastic claw 32 is formed on the guide wire sleeve locking sleeve 20, and the end of the outer guide wire locking member 30 is formed with the clamping cavity 22 for the elastic claw 32 to be inserted and squeezed to deform.

[0081] See also Figures 1 to 13In this embodiment, the inner wall of the clamping cavity 22 has a tapered end whose diameter decreases from back to front, and the front end outer edge of the elastic claw 32 is provided with a chamfered portion. In this way, as the outer guide wire lock 30 moves forward, the inner diameter of the clamping cavity 22 becomes smaller and smaller, and the chamfered portion can guide the elastic claw 32 to move.

[0082] See also Figures 1 to 13 A clamping sleeve 23 is formed on the guide wire sleeve locking sleeve 20, and the clamping cavity 22 is located in the clamping sleeve 23. It is easy to understand that a space for the front end of the outer sleeve 10 to be placed is formed between the outer wall of the clamping sleeve 23 and the inner wall of the guide wire sleeve locking sleeve 20.

[0083] In yet another embodiment, the guide wire sleeve locking sleeve 20 is embedded in the outer sleeve 10, and the clamping cavity 22 is formed in the middle of the rear end surface thereof.

[0084] See also Figures 1 to 13 An outer guide anti-loosening structure 10c is provided between the clamping sleeve 23 and the outer guide wire lock 30 to prevent the two from being separated in the axial direction of the outer sleeve 10. In this embodiment, the outer guide anti-loosening structure 10c includes an outer guide protrusion 33 convexly provided on the side wall of the outer guide wire lock 30, and an outer guide recess 24 formed on the inner wall of the clamping sleeve 23 and engaged with the outer guide protrusion 33. After the outer guide protrusion 33 is engaged with the outer guide recess 24, the positions of the guide wire sleeve locking sleeve 20 and the outer guide wire lock 30 in the axial direction of the outer sleeve 10 are maintained. It should be noted that the outer guide anti-loosening structure 10c is arranged at the position where the guide wire sleeve 202 is located when it is clamped, that is, when the guide wire sleeve 202 is clamped and fixed, the outer guide protrusion 33 and the outer guide recess 24 are engaged with each other, and the outer guide anti-loosening structure 10c is used to maintain the position of the clamping sleeve 23 and the outer guide wire locking member 30. In this way, the guide wire sleeve 202 is clamped and fixed and will not loosen at will. At this time, the inner guide wire 201 can be dragged and the guide wire sleeve 202 can be turned.

[0085] In other embodiments, an outer guide protrusion 33 is formed on the inner wall of the clamping sleeve 23 , and an outer guide recess 24 that cooperates and engages with the outer guide protrusion 33 is formed on the side wall of the outer wire guide lock 30 .

[0086] See also Figures 1 to 13 In the present embodiment, the outer guide protrusion 33 is extended along the entire circumference of the outer guide wire locking member 30, and the outer guide recess 24 is also extended along the entire circumference of the clamping sleeve 23, so that the guide wire sleeve locking sleeve 20 and the outer guide wire locking member 30 can rotate relative to each other, and even if they rotate, the positions of the clamping sleeve 23 and the outer guide wire locking member 30 can be maintained in the axial direction.

[0087] See also Figures 1 to 13In this embodiment, the guide wire sleeve locking sleeve 20 is sleeved on the end of the outer sleeve 10 and can rotate relative to the outer sleeve 10 with the axial direction of the outer sleeve 10 as the axis. It is worth mentioning that the guide wire sleeve 202 is made into a predetermined hook shape during the production process, and then after the inner guide wire 201 is loaded, the front end of the guide wire sleeve 202 is supported by the inner guide wire 201 to make it straight. After the guide wire sleeve 202 is clamped and fixed by the gripping structure 10a, the inner guide wire 201 is pulled backward by a preset distance. Similarly, the front end of the guide wire sleeve 202 is deformed into the predetermined hook shape due to the withdrawal of the inner guide wire 201 to hook the patient's surgical site. Since the guide wire sleeve locking sleeve 20 and the outer sleeve 10 can rotate relatively, and the outer guide wire locking member 30 is pressed onto the guide wire sleeve locking sleeve 20, the front end of the guide wire sleeve 202 in the shape of a hook can be rotated to a certain angle by rotating the guide wire sleeve locking sleeve 20, so as to better hook the site, thereby improving the operating efficiency and ensuring the normal implementation of the operation.

[0088] In other embodiments, the guide wire sleeve locking sleeve 20 can be fixed to the end of the outer sleeve 10 by threading, or can be fixed to the end of the outer sleeve 10 by snap-fitting.

[0089] See also Figures 1 to 13 , a locking ring 11 is formed on the side wall of the outer sleeve 10, and a locking groove 25 engaging with the locking ring 11 is provided on the inner side wall of the guide wire sleeve locking sleeve 20. In this embodiment, the number of the locking rings 11 is but not limited to two, and the two locking rings 11 extend along the entire circumference of the outer sleeve 10 and are arranged at intervals in the axial direction of the outer sleeve 10. It is easy to understand that the locking ring 11 is inserted into the locking groove 25 of the outer sleeve 10 to lock the outer sleeve 10 with the outer sleeve 10 in the axial direction of the outer sleeve 10, and the two can rotate relatively.

[0090] See also Figures 1 to 13 A steering positioning structure 10d is provided between the outer sleeve 10 and the guide wire sleeve locking sleeve 20 to position the guide wire sleeve locking sleeve 20 after rotation. In this embodiment, the steering positioning structure 10d includes a steering positioning protrusion 26 formed on the guide wire sleeve locking sleeve 20, and a steering positioning recess 12 formed on the outer sleeve 10 for the steering positioning protrusion 26 to slide in and out. The number of the steering positioning protrusion 26 is but not limited to one, and the number of the steering positioning recess 12 is multiple, and they are arranged at intervals in the circumferential direction of the outer sleeve 10.

[0091] Specifically, a mounting flange 13 is convexly provided on the side wall of the outer sleeve 10, the steering positioning recess 12 is located on the end surface of the mounting flange 13, and the steering positioning protrusion 26 is convexly provided on the rear end surface of the guide wire sleeve locking sleeve 20. It is easy to understand that the use of the steering positioning structure 10d can lock the position of the guide wire sleeve locking sleeve 20 in the circumferential direction to prevent it from rotating when it is not necessary to rotate, and when rotating, the position after rotation can be locked.

[0092] See also Figures 1 to 13 The inner sleeve component 40 is roughly cylindrical and is used to move the outer wire lock 30. The inner sleeve component 40 is arranged in the outer sleeve 10 and connected to the outer wire lock 30, and can move along the axial direction of the outer sleeve 10. In this embodiment, the inner sleeve component 40 and the outer sleeve 10 are clearance-fitted, and the outer wire lock 30 is rotatably arranged on the inner sleeve component 40. The inner sleeve component 40 has a guide wire receiving groove 41 for the inner guide wire 201 to pass through and a concave cavity 42 connected to the guide wire receiving groove 41. The concave cavity 42 is located in the rear half of the inner sleeve component 40 and is opened toward the rear. The front end of the inner sleeve component 40 is provided with a flange limiting groove 43. The outer guide wire lock component 30 has a flange end 34 located at its rear end, and the flange end 34 is inserted into the flange limiting groove 43. Since the flange limiting groove 43 limits the flange end 34 of the outer guide wire lock component 30 in the axial direction of the outer sleeve 10, the forward and backward movement of the inner sleeve component 40 can drive the outer guide wire lock component 30 to move forward and backward. After the guide wire sleeve 202 is tightened, the rotation of the guide wire sleeve locking sleeve 20 can cause the outer guide wire lock component 30 to rotate relative to the inner sleeve component 40. It is worth mentioning that the outer guide wire locking member 30 , the inner sleeve member 40 , and the outer sleeve 10 are coaxially arranged, and the outer guide wire through groove 31 , the guide wire receiving groove 41 , and the concave cavity 42 are sequentially connected in the axial direction of the outer sleeve 10 .

[0093] See also Figures 1 to 13 The inner wire locking sleeve 50 includes an inner locking sleeve portion 51 slidably disposed in the concave cavity 42, and has a cross section in the shape of but not limited to a circle, and a clearance fit is adopted between the inner locking sleeve portion 51 and the concave cavity 42 of the inner sleeve member 40.
