Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a guidewire rotation controller and a guidewire rotation control method. Background Technology

[0002] Endovascular interventional surgery is a procedure that uses instruments such as puncture needles, guidewires, and catheters to perform diagnosis and treatment through blood vessels under the guidance of medical imaging equipment. Among these instruments, guidewires are the basic instruments and are used in large quantities and in many different scenarios.

[0003] When inserting a guidewire into a blood vessel, a guidewire control device is needed to control the feed and rotation of the guidewire. One known guidewire control device includes a handle, a clamp, and a fixing component. The fixing component has a through-hole with an internal thread. The clamp is located at the end of the handle, which is hollow and has external threads. In actual use, the guidewire is passed sequentially through the handle, clamp, and through the through-hole. The handle is then threaded into the fixing component. During connection, the clamp is gradually pushed into the conical space within the through-hole. The inner wall of the conical space compresses the clamp, clamping the guidewire and securing it. The guidewire can then be fed and rotated by manipulating the handle. Although this guidewire control device has a simple structure, it cannot precisely control the guidewire rotation angle. The rotation angle control relies entirely on the operator's feel and experience, and is limited by the operator's hand stability and fatigue, resulting in low accuracy in guidewire rotation angle control.

[0004] Therefore, there is an urgent need for a guide wire rotation controller with high precision in controlling the guide wire rotation angle. Summary of the Invention

[0005] The purpose of this invention is to provide a guide wire rotation controller and a guide wire rotation control method to solve the problems existing in the prior art.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The purpose of this invention is to provide a guide wire rotation controller and a guide wire rotation control method to solve the problems existing in the prior art. By setting a rotation angle visual magnifier on the fixture, the control accuracy of the guide wire rotation angle is improved by using the scale lines on the rotation angle visual magnifier without affecting the guide wire rotation control.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to the following: Figures 1-5 As shown, a guide wire spin control device is provided, including: a clamp and a spin angle magnifying component 2; the clamp includes a locking component 3, a clamping component 4, and a hollow handle 5. The locking component 3 has a through-hole in the middle, and the connecting hole includes an insertion section, an internal thread section, and a tapered section arranged sequentially in the direction away from the handle 5. The end of the handle 5 is provided with the clamping component 4. The side of the clamping component 4 away from the locking component 3 of the handle 5 is provided with an external thread section and a plug-in section. The external thread section of the handle 5 is threadedly connected to the internal thread section of the connecting hole of the locking component 3. The plug-in section of the handle 5 is inserted into the insertion section of the connecting hole. The clamping component 4 extends into the tapered section. The tapered section of the locking component 3 squeezes the clamping component 4 to close it, thereby fixing the positional relationship between the guide wire 1 and the clamp; the clamping component 4 mainly includes multiple clamping blocks, which are evenly distributed around the axis of the handle 5, and the clamping blocks themselves can be oriented towards the hand when squeezed. The axis of the handle 5 undergoes bending motion; the rotation angle visual magnifier 2 is annularly sleeved on the outer circumference of the handle 5, and the rotation angle visual magnifier 2 rotates synchronously with the handle 5. The outer circumferential wall of the rotation angle visual magnifier 2 is provided with scale lines 6 for displaying the rotation angle. The scale lines 6 designed on the rotation angle visual magnifier 2 can provide the operator with clear rotation angle information, thereby improving the control accuracy of the guidewire 1 rotation angle. Moreover, the rotation angle visual magnifier 2 is directly sleeved on the rotary body, and the connection and disassembly of the two are highly convenient. At the same time, the rotation angle visual magnifier 2 can be directly adapted to the guidewire rotation controller (i.e., clamp) known to the applicant. In actual production, only the corresponding rotation angle visual magnifier 2 needs to be produced, further reducing production costs. Even if the overall production is carried out, the overall structure of the clamp and the rotation angle visual magnifier 2 still has the advantages of simple structure, low cost, and easy market promotion.

[0024] When the angle magnifying lens 2 is applied to the wire guide control known to the applicant, that is, when only the angle magnifying lens 2 is produced, the inner diameter of the position where the angle magnifying lens 2 and the fixture are fitted should be designed to be slightly smaller than the outer diameter of the handle rod 5. The two should be connected by an interference fit to ensure that when the entire wire guide control is rotated by the angle magnifying lens 2, there is no relative slippage between the angle magnifying lens 2 and the handle rod 5, thus ensuring the accuracy of the rotation angle data.

[0025] During overall production, a key block can be additionally set on the outer peripheral wall of the handle rod 5 along the axial direction, and a keyway can be set on the inner peripheral wall at the position where the angle magnifying lens 2 and the fixture are fitted. The keyway needs to pass through the angle magnifying lens 2 along the axial direction. The key block and the keyway can be used to ensure that there is no relative sliding between the angle magnifying lens 2 and the handle rod 5, and ensure the accuracy of the rotation angle data.

[0026] When carrying out overall production, the rotation angle magnifier 2 and the handle rod 5 can also be designed as an integrated structure to ensure the accuracy of the rotation angle data.

[0027] The handle 5 is provided with an annular flange 7. When the handle 5 and the locking member 3 are rotated into place and the clamping member 4 clamps the guide wire 1, the annular flange 7 fits against the end of the locking member 3 to limit the movement. That is, the annular flange 7 can be used to prevent the handle 5 from being over-screwed.

[0028] Based on the setting of the annular flange 7, a receiving groove is set on the inner peripheral wall of the position where the angular magnifying component 2 and the handle rod 5 are fitted, near the locking component 3. The receiving groove matches the annular flange 7, and the annular flange 7 can be used as a limiting component to restrict the fitting position of the angular magnifying component 2.

[0029] The outer diameter of the annular flange 7 can be set to be smaller than the outer diameter of the end face of the locking part 3 near the handle rod 5. At the same time, the receiving groove is set at the end of the overall rotating angle visual magnifying part 2 near the locking part 3. With this design, after the rotating angle visual magnifying part 2 is put into place, its end face fits with the end face of the locking part 3, which improves the aesthetics of the overall structure and reduces the existence of structural gaps.

[0030] The rotating visual magnifying component 2 includes a fitting part and a screwing part. The fitting part and the screwing part are fixedly connected. They can be detachably fixed by bolts or set as one piece. The fitting part is fitted around the outer periphery of the handle rod 5. The outer diameter of the screwing part is larger than the outer diameter of the fitting part. The screwing part is located on the side of the fitting part away from the locking part 3. The screwing part with a larger outer diameter provides a larger base for hand-held operation, which facilitates the improvement of operation convenience.

[0031] In this embodiment, the rotating visual magnifier 2 has a bowl-shaped structure. The bottom of the bowl is divided into a fitting part, and the rim is a rotating part (the rotating part is configured to have geometric dimensions that allow the surgeon's thumb and forefinger to grip the outer edge of the rim). The curved surface of the bowl-shaped structure can improve the surgeon's grip and increase the comfort of operation. In other embodiments, the rotating visual magnifier 2 can also be designed with other shapes, such as a convex U-shaped structure with a plane perpendicular to the axial direction as the transition surface between the rotating part and the fitting part, which aims to provide a rotating part with a larger outer diameter.

[0032] Graduation lines 6 can be set circumferentially on the fitting part and the screwing part respectively. The accuracy of the graduation line 6 on the fitting part is greater than that of the graduation line 6 on the screwing part. At this time, the graduation line 6 on the screwing part can be used as the coarse adjustment graduation and the graduation line 6 on the fitting part can be used as the fine adjustment graduation. In actual use, a fast coarse adjustment can be performed first, followed by a slow fine adjustment to improve the efficiency of rotation angle control.

[0033] The scale line 6 set on the screw head can be either a raised scale line or a grooved scale line. Both designs can improve the stability of operation and prevent slippage during the rotation of the screw head.

[0034] A method for controlling the rotation of a guidewire using the guidewire rotation controller of this embodiment is provided, comprising the following steps: S1: Pass the guide wire 1 through the handle rod 5, the clamping member 4 and the locking member 3 in sequence; S2: By turning the handle rod 5, the clamping part 4 is driven to move. By utilizing the characteristic that the inner diameter of the conical surface inside the locking part 3 gradually decreases, the clamping part 4 is squeezed to fix the guide wire 1. S3: Control the rotation angle vision magnifier 2 to rotate, which drives the clamp to rotate, and the clamped and fixed guide wire 1 follows the rotation; S4: Select a reference object (such as the incision line of the surgical site), and with the scale line 6, obtain the current rotation angle in real time during the rotation process, and then obtain the rotation angle of the guidewire 1.

[0035] Example 2: Please refer to the following: Figures 6-15 As shown, the difference between this embodiment and Embodiment 1 is that the guide wire spin controller also includes a stepping control component 8, a locking component 3 and a spin angle visual magnifying component 2, which are fixedly connected. The fixed connection can be a bolt-type fixed connection or an integral setting. The locking component 3 is only rotatably set in the stepping control component 8. Specifically, the stepping control component 8 has a through hole for the guide wire 1 to pass through. The locking component 3 is only rotatably set in this through hole. The outer periphery of the stepping control component 8 is provided with multiple slots 9. The spin angle visual magnifying component 2 is provided with a locking component 10 for locking into the slots 9. The locking component 10 and the spin angle visual magnifying component 2 are provided with a... An elastic element is provided to allow the locking member 10 to disengage from the slot 9. The rotation of the angle magnifying element 2 is controlled by the axis of the stepping control element 8. The locking member 10 moves circumferentially along the stepping control element 8. By overcoming the elastic force of the elastic element, the locking member 10 slides between multiple slots 9. In this structure, during the rotation of the angle magnifying element 2, the locking member 10 continuously disengages from the slot 9 and slides to other slots 9, springing back into the slot 9 by the elastic force. This provides significant vibration and sound feedback, improving the accuracy of angle control and thus assisting in improving the control precision of the guide wire 1's rotation angle. In this embodiment, the angle magnifying element 2 has a bowl-shaped structure, with the bowl-shaped opening being the screwing part. The main body of the stepping control element 8 has a finger gripping part (the finger gripping part typically surrounds the guide wire and has a length extending along the long axis of the guide wire, for example, attached...). Figure 9The tubular main body is designed with a rotating part that allows the surgeon's thumb and forefinger to grip the outer edge of the bowl. The finger gripping part of the stepping control 8 is designed with an outer contour geometry that allows the surgeon's thumb and forefinger to grip it. The rotation angle visual magnifier 2 can rotate relative to the finger gripping part of the stepping control 8 (the rotation angle visual magnifier 2 rotates the guidewire around its axis to the desired angle with the finger gripping part of the stepping control 8 as a stationary reference frame). When the surgeon uses the guidewire rotation controller to perform 3D torsion control of the distal end of the guidewire (generally the end closer to the patient) under fluoroscopy, it usually requires the cooperation of two hands. One hand (fingers) grips the finger gripping part to fix the stepping control 8, and the other hand (fingers) grips the rotating part to rotate the rotation angle visual magnifier 2.

[0036] In this embodiment, the total number of steps for the rotation angle visual magnifier 2 to rotate one revolution (i.e., the starting point and the ending point coincide) is limited by the step control component 8; for example, attached Figure 9 In this design, the stepper control component 8 has 30 equally spaced slots 9 arranged circumferentially. Therefore, the rotation angle (i.e., step angle) of the rotational visual magnifier 2 in one complete step is 12 degrees, and the total number of steps for the rotational visual magnifier 2 to rotate one full revolution (360 degrees) is 30. The step angle is a fixed value. The number of equally spaced slots 9 arranged circumferentially on the stepper control component 8 can be 15, 20, 30, 40, or 60. Alternatively, the number of equally spaced slots 9 arranged circumferentially on the stepper control component 8 can be 10 to 130.

[0037] In this embodiment, the locking member 3 and the stepping control member 8 are configured to rotate only as follows: the inner peripheral wall of the stepping control member 8 is provided with a limiting ring 11, and the outer peripheral wall of the locking member 3 is provided with an annular limiting protrusion 12. The end of the annular limiting protrusion 12 near the rotating angle visual magnifier 2 contacts the end of the limiting ring 11 away from the rotating angle visual magnifier 2. The end of the stepping control member 8 near the rotating angle visual magnifier 2 contacts the rotating angle visual magnifier 2. In this structure, the rotating angle visual magnifier 2 restricts the stepping control member 8 from moving towards the handle rod 5, and the annular limiting protrusion 12 restricts the stepping control member 8 from moving away from the handle rod 5 by restricting the limiting ring 11 from the inside, thus realizing the interaction between the stepping control member 8 and the locking member. While axial relative movement between the locking element 3 and the stepping control element 8 is not possible, this does not affect the rotation of the locking element 3 within the stepping control element 8. The stepping control element 8 is made of a deformable self-recovering material, such as plastic. This material allows the locking element 3 to be directly inserted into the stepping control element 8, but the limiting ring 11 or the annular limiting protrusion 12 needs to have a certain guiding function to push open the limiting ring 11 during insertion. For example, the cross-section of the limiting ring 11 or the annular limiting protrusion 12 is semi-circular or trapezoidal. Under this structure, the locking element 3 and the stepping control element 8 are detachably connected. In other embodiments, the locking element 3 and the stepping control element 8 can also be connected by bearings to improve the smoothness of rotation, but this will increase production costs to some extent.

[0038] In this embodiment, the elastic element is a spring 13. An annular groove is provided on the end face of the angular magnifying component 2 near the stepping control component 8. The part of the stepping control component 8 with a slot 9 is inserted into the annular groove. The angular magnifying component 2 is provided with a mounting hole 14 radially corresponding to the slot 9. The spring 13 is installed in the mounting hole 14. The end of the spring 13 near the slot 9 is connected to a locking component 10. The mounting hole 14 provides a stable deformation direction for the spring 13, ensuring that the radial movement of the locking component 10 does not produce deviation, and avoiding the situation where the angular magnifying component 2 gets stuck. In other embodiments, the spring 13 can also be replaced with a column structure with elastic self-recovery capability, such as a rubber column, and such a column structure can be used as the elastic element.

[0039] The spring 13 can be directly installed in the mounting hole 14, or a mounting sleeve 15 can be fitted around the spring 13. One end of the mounting sleeve 15 is closed and the other end is open. A locking member 10 is provided at the open end. The spring 13 is placed between the locking member 10 and the closed end of the mounting sleeve 15. The mounting sleeve 15 can then be placed in the mounting hole 14.

[0040] A mounting hole 14 can be provided that radially penetrates the rotating angle vision magnifier 2, allowing the locking member 10 and the spring 13 to be directly inserted into the mounting hole 14 from the outside of the rotating angle vision magnifier 2, thus facilitating the installation of the spring 13 and the locking member 10. The rotating angle vision magnifier 2 is provided with a limiting hole 16, which communicates with the mounting hole 14. Specifically, the limiting hole 16 intersects the axis of the mounting hole 14, and a limiting member 17 is inserted into the limiting hole 16. By inserting the limiting member 17, the spring 13 is intercepted on the path of radial sliding out of the mounting hole 14, thereby positioning the end of the spring 13 away from the locking member 10. The limiting member 17 can be a rod-shaped structure or a plate-shaped structure, designed to be able to be inserted into the limiting hole 16 and extend into the mounting hole 14 to intercept and position the spring 13.

[0041] Multiple slots 9 form a gear structure, which improves the continuity of the slots 9. The gear teeth are rounded, which improves the smoothness of the locking member 10 sliding between the slots 9.

[0042] The number of slots 9 in the gear structure can be determined based on the accuracy of the scale line 6 on the sleeve part of the angle magnifying component 2. For example, if the difference between adjacent scales of the sleeve part is 12°, there will be 30 lines representing degrees. The slots 9 can be designed to be 30, each corresponding to a line representing a degree, which can further improve the recognizability of angle control.

[0043] To further improve the smoothness of the sliding of the locking component 10 between multiple slots 9, the locking component 10 can be directly selected as a spherical structure, or a cylindrical structure with a hemispherical or arc-shaped surface at one end near the slot 9.

[0044] A method for controlling the rotation of a guidewire using the guidewire rotation controller of this embodiment is provided, comprising the following steps: S1: Connect the rotating angle vision magnifier 2 with the locking component 3 to the stepping control component 8, and pass the guide wire 1 through the handle rod 5, the clamping component 4, the locking component 3 and the stepping control component 8 in sequence; S2: By turning the handle rod 5, the clamping part 4 is moved, and the guide wire 1 is fixed by the conical surface in the locking part 3 pressing the clamping part 4. S3: Rotate the angle magnifying lens 2 to drive the clamp to rotate. The guide wire 1, which is clamped and fixed, rotates accordingly. At the same time, the locking piece 10 set on the angle magnifying lens 2 by the spring 13 continuously engages into different slots 9, giving the operator corresponding rotational feedback. S4: Select a reference object (such as the incision line of the surgical site), and with the scale line 6, obtain the current rotation angle in real time during the rotation process, and then obtain the rotation angle of the guidewire 1.

[0045] Any adaptive changes made according to actual needs are within the scope of protection of this invention.

[0046] As attached Figure 4 and attached Figure 11 As shown, the scale lines 6 (or other markings, such as color blocks or graphics) deployed on the rotating visual magnifier 2 and the rotating part have different densities and all indicate the same step angle.

[0047] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
