Description

TECHNICAL FIELD

[0001] The application relates to the technical field of medical devices, in particular to a guide wire intervention auxiliary device for a cardiovascular internal medicine department. BACKGROUND

[0002] In clinical diagnosis and treatment of the cardiovascular internal medicine department, guide wire intervention technology is a core means for implementing intravascular diagnosis and treatment, and is widely used in key surgical links such as coronary angiography, stent implantation and balloon dilation. As the “advance guard” of the intervention surgery, the guide wire needs to be precisely passed through the winding and tortuous blood vessel passage and reach the target lesion area, and the stability and accuracy of the operation directly determine the success of the surgery and the safety of the patient.

[0003] In current clinical practice, the pushing, rotation and angle control of the guide wire are mainly completed manually by the operator. In the specific operation, the doctor needs to continuously pinch the end of the guide wire with the fingers, maintain the control of the guide wire by the gripping force of the fingertips, and adjust the pointing angle of the front end of the guide wire through the coordinated rotation of the wrist and the fingers to adapt to the complex anatomical structures such as blood vessel bifurcation and bending.

[0004] However, pinching the guide wire requires a very high finger force and operation endurance of the operator. Since the guide wire is small in diameter and has a low-friction coating such as polytetrafluoroethylene on the surface to reduce blood vessel damage, the friction of the fingertips is very small. In order to prevent the guide wire from slipping during pushing or rotation, the doctor needs to continuously apply a large gripping force, and long-time operation can easily cause finger muscle fatigue and spasm, which not only increases the physical burden of the operator, but also may cause the guide wire to lose control due to unstable gripping force, resulting in scratches on the blood vessel wall.

[0005] On the other hand, there is always a risk of guide wire falling off the hand. During the surgery, factors such as blood reflux and saline flushing can further reduce the friction of the guide wire surface, and the doctor needs to frequently switch instruments and adjust the operation posture during the surgery, so the gripping force of the fingertips on the guide wire is prone to fluctuate instantaneously. Once the guide wire falls off the hand, it may be suddenly displaced along with the blood flow inertia, and the sharp front end or rigid section of the guide wire is extremely easy to scratch or even pierce the blood vessel wall. Therefore, a guide wire intervention auxiliary device for the cardiovascular internal medicine department is proposed to solve the above problems. SUMMARY

[0024] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-8 This invention provides a technical solution: a cardiovascular guidewire interventional auxiliary device, comprising a catheter end 1 and a guidewire body 2. An adjustment section 5 is provided on the outside of the catheter end 1 for rotating and advancing the guidewire. A control section 6 is provided on the adjustment section 5 for convenient manipulation of the guidewire direction by the surgeon. A clamping section 7 is provided on the control section 6 for easier clamping of the guidewire and reduced hand fatigue. A locking section 9 is provided on the clamping section 7 for automatically locking the position of the control section 6, ensuring that the guidewire is positioned without obstructing the surgical process. The adjustment section 5 includes two adjustment rods 53, each with a slot 54. The control section 6... The system includes a control ring 61 with rod holes 62 corresponding to the adjusting rods 53. The two adjusting rods 53 are slidably connected to the corresponding rod holes 62. The control ring 61 has an adjusting hole 63. The clamping part 7 includes a clamping plate 71, which is slidably connected in the adjusting hole 63. The locking part 9 includes a pin 91, which is connected to the clamping plate 71. A support arm 92 is hinged to the pin 91. A slide rod 93 is connected to the control ring 61. The support arm 92 has a sliding hole 94 and is slidably connected to the slide rod 93 through the sliding hole 94. An insert block 95 is connected to the end of the support arm 92 and is inserted into the slot 54 of the adjusting rod 53.

[0026] In this embodiment, there are two adjustment holes 63. The inner walls of both adjustment holes 63 are provided with guide grooves 64 and are symmetrically arranged. The clamping part 7 also includes a grip hole 72, which further improves the ease of operation for the surgeon's fingers. The grip hole 72 is located on the clamping plate 71, and a guide arm 73 is fixedly connected to the clamping plate 71. The clamping plate 71 is slidably connected to the guide groove 64 via the guide arm 73. The guiding action ensures the sliding stability of the clamping plate 71. An anti-slip pad 74 is fixedly connected to the end face of the clamping plate 71. The anti-slip pad 74 is used for... To replace the finger clamping of the guide wire, the clamping part 7 is provided with a reset part 8. The reset part 8 includes a support block 81, which is fixedly connected to the clamp plate 71. A support block 82 is fixedly connected to the control ring 61. Magnets 83 are connected to the sides of the support blocks 81 and 82 that are close to each other. The two magnets 83 are attracted to each other by opposite poles. A tension spring 84 is elastically connected between the support blocks 81 and 82. The tension spring 84 pulls to reset the position of the clamp plate 71. The attraction of the magnets 83 can stabilize the clamp plate 71 and prevent it from shaking during the operation.

[0027] To further improve the ease of control over the guidewire, there are two clamping parts 7, two resetting parts 8, and two locking parts 9. The other locking part 9 and the resetting part 8 are both connected to the clamping plate 71 and the control ring 61 of the other clamping part 7. The insert 95 of the other locking part 9 is inserted into the slot 54 of the other adjusting rod 53. The other clamping part 7 is set in the other adjusting hole 63. The two clamping parts 7 and the resetting part 8 are symmetrically arranged. After the guidewire is inserted, the clamping plate 71 is released, and the clamping plate 71 is reset by the tension spring 84. At the same time, the support arm 92 moves in a curved motion and causes the insert 95 to automatically insert into the corresponding slot 54, completing the suspension and fixation of the control ring 61, so that the surgical instruments can smoothly pass through the guidewire into the catheter and be delivered to the patient.

[0028] It is worth noting that an installation part 3 is provided on the end of the conduit 1 for installing the adjustment part 5 and the positioning tool. The installation part 3 includes a retainer 31, a support rod 32 is fixedly connected to the outer wall of the retainer 31, a rotating sleeve 33 is fixedly connected to the end of the support rod 32, and an annular groove 34 is opened on the inner wall of the rotating sleeve 33. The retainer 31 is snapped into the end of the conduit 1. The guide wire body 2 is set inside the end of the conduit 1, and the end of the guide wire body 2 is located between two anti-slip pads 74. The adjustment part 5 also includes a rotating ring 51, which is rotatably connected to the inner wall of the rotating sleeve 33. A limiting ring 52 is fixedly sleeved on the rotating ring 51 and is rotatably connected to the annular groove 34. The rotating ring 51 is limited in the rotating sleeve 33 and will not come off. Both adjustment rods 53 are fixedly connected to the rotating ring 51.

[0029] It is worth noting that the installation part 3 is provided with a positioning part 4, which is used to position the auxiliary tool of this case on the surgical position on the patient. The positioning part 4 includes two support plates 41, which are fixedly connected to the outer wall of the rotating sleeve 33. A rotating rod is rotatably connected between the two support plates 41. Positioning arms 42 are fixedly sleeved at both ends of the rotating rod. An adhesive plate 43 is rotatably connected between the two positioning arms 42. The adhesive plate 43 can be adhered and fixed to the patient's skin with double-sided adhesive. There are three positioning parts 4, all of which are connected to the rotating sleeve 33. The distance between each pair of positioning parts 4 is 120 degrees. By reasonably rotating the positioning arms 42 on the three positioning parts 4, the three adhesive plates 43 are triangularly fixed on the patient's body, thereby achieving the support and positioning of the entire auxiliary tool.

[0030] Working principle: The ferrule 31 of the installation part 3 is snapped into the catheter end 1. The rotating sleeve 33 connected to the support rod 32 serves as the basic structure. Three positioning parts 4 are distributed at 120° on the outer wall of the rotating sleeve 33. The adhesive plate 43 of each positioning part 4 is attached to the patient's skin with double-sided adhesive. The positioning arm 42 can rotate and the adhesive plate 43 can be adjusted in angle to achieve overall fixation of the device. The rotating ring 51 of the adjustment part 5 is rotatably connected to the inner wall of the rotating sleeve 33. The limiting ring 52 is snapped into the annular groove 34 of the rotating sleeve 33 to ensure that the rotating ring 51 can rotate freely and does not detach, providing a basis for guidewire angle adjustment.

[0031] The doctor inserts his finger into the gripping hole 72 of the splint 71 and pinches the two symmetrical splints 71 inward. The splint 71 slides along the adjustment hole 63 of the control ring 61, and the guide arm 73 moves along the guide groove 64 to ensure stability. The anti-slip pad 74 on the end face of the splint 71 clamps the end of the guide wire body 2. The anti-slip pad 74 increases the friction and prevents the guide wire from slipping.

[0032] During clamping, the clamping plate 71 drives the pin 91 to move, causing the support arm 92 to rotate around the slide rod 93. The insertion block 95 disengages from the slot 54 of the adjusting rod 53, releasing the lock between the control ring 61 and the adjusting rod 53. The control ring 61 can slide along the adjusting rod 53, facilitating the stable entry and exit of the guide wire during clamping. When the clamping plate 71 is released, the tension spring 84 of the reset part 8 contracts, and the opposite poles of the magnet 83 attract each other, causing the clamping plate 71 to reset. The support arm 92 moves in the opposite direction, causing the insertion block 95 to re-insert into the slot 54, automatically locking the position of the control ring 61.

[0033] The control ring 61 drives the two adjusting rods 53 to rotate synchronously, thereby rotating the rotating ring 51 of the adjusting part 5, changing the angle of the clamped guidewire to adapt to the complex vascular path. In the unlocked state, the control ring 61 is pushed to slide along the adjusting rod 53, and the clamping part 7 drives the guidewire to be pushed or retracted along the catheter end 1. The multiple slots 54 on the adjusting rod 53 are adapted to the locking requirements of different positions, realizing precise control of guidewire advance and retreat.
