Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a guiding wire coil positioning device and a using method thereof. Background Art

[0002] At present, interventional therapy is a new treatment method between surgery and medical treatment. It is the treatment method with the least trauma. A tiny channel is made on the blood vessel or skin, and the lesion part is treated locally under the guidance of imaging equipment. Usually, a guide wire is used to assist the catheter to be placed into the lesion part of the patient.

[0003] Currently, most interventional surgeries are manually operated by doctors, and there are still relatively big problems. On the one hand, in order to facilitate the doctor's operation, the patient needs to lie on the hospital bed in the posture designated by the doctor, and the long operation process will cause a burden on the patient. On the other hand, the doctor needs to be irradiated by X-rays for a long time during the operation, which is harmful to the body. At the same time, interventional surgery also has relatively high requirements for the doctor's operation experience. A slight tremor of the hand during puncture will cause certain injuries to the patient.

[0004] To solve the above problems, a guiding wire coil positioning device and a using method thereof are provided herein.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Invention

[0023] Further, an annular airbag is fixed in the through hole, and the guide wire passes through the center of the airbag.

[0024] The usage method of the above positioning device includes the following steps:

[0025] S1: Install the guide wire

[0026] Insert one end of the guide wire between the first clamping block and the second clamping block, and the other end passes through the airbag. The end of the guide wire passing through the airbag is the insertion end. Push the clamping member into the space between the limiting strip and the placement box to fix the guide wire on the clamping member. Inflate the airbag to fill the gap between the guide wire and the through hole, so as to ensure that the insertion end of the guide wire is perpendicular to the first connecting plate. Pull the insertion end of the guide wire to straighten the guide wire. Start the sixth motor to control the first incomplete gear to rotate clockwise. Then, the first incomplete gear meshes with the third rack to control the third sliding rod to move towards the side close to the second driving strip, thereby lifting the second driving strip, driving the second driving strip to squeeze the inclined surface of the driving block to make the driving block move towards the side close to the second connecting plate, and then controlling the two clamping plates to move closer to each other to clamp the insertion end of the guide wire.

[0027] At the same time, the convex block moves away from the L-shaped connecting plate, and the fixing strip is squeezed by the convex block and moves away from the third sliding rod, so that the clamping block is disengaged from the first gear to release the limit on the first gear. When the end of the third rack close to the L-shaped connecting plate is disengaged from the first incomplete gear, the first incomplete gear continues to rotate clockwise, and the third sliding rod stops moving. Continue to start the sixth motor, and the third incomplete gear begins to mesh with the first gear, so as to drive the first gear to rotate, and then drive the wire take-up reel to rotate, so as to realize the winding of the rope. After winding until the rope is straightened, turn off the sixth motor.

[0028] S2: The patient takes the position

[0029] The patient lies on the hospital bed in a comfortable position, and the part to be punctured of the patient is exposed to the outside.

[0030] S3: Adjust the position of the positioning and guiding device

[0031] By starting the fifth motor to control the positioning and guiding device to move within the track, the positioning and guiding device is moved to a position convenient for puncture. When moving to the corner of the track, the fourth motor is started to control the second gear to rotate 90°, so that the second gear meshes with the first rack or the second rack adjacent to the previous moving position. Through the cooperation and adjustment of the first cylinder, the first motor, the second motor, the second cylinder and the third motor, the insertion end of the guide wire is aligned with the puncture site to be punctured.

[0032] S4: Perform puncture

[0033] Start the sixth motor again to control the first incomplete gear to rotate clockwise, thereby driving the second incomplete gear and the third incomplete gear to rotate. At the same time, the second incomplete gear starts to mesh with the fourth rack, and the third incomplete gear starts to mesh with the first gear, so that the second connecting plate moves toward the puncture site side of the patient, thereby driving the splint to move, so as to traction the guide wire clamped between the two splints toward the puncture site of the patient. At the same time, while the guide wire is being tractioned, the first gear drives the take-up reel to rotate, and one end of the rope can be wound up. During the process of winding up the rope, the clamping member is pulled toward the side close to the first connecting plate.

[0034] When the teeth of the first incomplete gear start to disengage from the third rack, the second spring starts to contract, and the two splints move away from each other to loosen the guide wire. At the same time, the second driving bar is pushed toward the side close to the L-shaped connecting plate, so that the third sliding rod is extruded by the second driving bar and moves toward the side close to the L-shaped connecting plate, so that the convex block disengages from the fixed bar. Under the elastic force of the fifth spring, the block is stuck on the first gear to realize the limit of the first gear. Then the second incomplete gear starts to disengage from the fourth rack, and the first spring starts to elongate, pulling the second connecting plate and the splint back to the initial position. When the second incomplete gear meshes with the fourth rack again, the next round of traction is started.

[0035] A guiding wire coil positioning device and its using method proposed by the present invention can bring the following beneficial effects:

[0036] 1. The positioning device of the present invention controls the positioning and guiding device to move within the track by starting the fifth motor, and moves the positioning and guiding device to a position convenient for puncture. Through the cooperation and adjustment of the first cylinder, the first motor, the second motor, the second cylinder and the third motor, the insertion end of the guide wire is aligned with the puncture site to be punctured. Therefore, when inserting the guide wire, it only requires the puncture site of the patient to be exposed to the outside, so that the patient can choose his own lying posture on the hospital bed according to comfort. Moreover, the positioning device has a high degree of automation, is convenient for doctors to operate remotely, can avoid doctors being irradiated by X-rays for a long time, and can also reduce the requirements for doctors' operation experience;

[0037] 2. While the positioning device of the present invention is pulling the guide wire, the first gear drives the winding shaft to rotate, which can wind one end of the rope. During the process of winding the rope, the clamping member is pulled to move towards the side close to the first connecting plate, so as to ensure that both ends of the guide wire move simultaneously, making the guide wire as straight as possible during the traction process, avoiding bending or knotting during the traction of the guide wire, which may affect the subsequent traction, and also preventing the guide wire from protruding from the placement box, which may affect the overall appearance of the positioning device;

[0038] 3. The positioning device of the present invention places the straightened guide wire coil in the placement box. On the one hand, it is convenient for its installation. On the other hand, it avoids chaos during the subsequent guiding of the guide wire coil. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the first cylinder 31 is fixed on the second fixing block 356.

[0070] The usage method of the above positioning device includes the following steps:

[0071] S1: Install the guide wire 4

[0072] By inserting one end of the guide wire 4 between the first clamping block 337 and the second clamping block 338, and the other end passing through the airbag 314, the end of the guide wire 4 passing through the airbag 314 is the inserted end. By pushing the clamping member into the space between the limiting strip 345 and the placement box 311, the guide wire 4 is fixed on the clamping member. By inflating the airbag 314 to fill the gap between the guide wire 4 and the through hole 313, it can be ensured that the inserted end of the guide wire 4 is perpendicular to the first connecting plate 312. By pulling the inserted end of the guide wire 4, the guide wire 4 is straightened. By starting the sixth motor to control the first incomplete gear 332 to rotate clockwise, then the first incomplete gear 332 meshes with the third rack 330 to control the third sliding rod 328 to move towards the side close to the second driving strip 326, thereby driving the second driving strip 326 to squeeze the inclined surface of the driving block 321 so that the driving block 321 moves towards the side close to the second connecting plate 317, and then controlling the two clamping plates 320 to move closer to each other to clamp the inserted end of the guide wire 4.

[0073] At the same time, the convex block 352 moves away from the L-shaped connecting plate 327, and the fixing strip is squeezed by the convex block 352 to move away from the third sliding rod 328, so that the clamping block disengages from the first gear 347 to release the limit on the first gear 347. When the end of the third rack 330 close to the L-shaped connecting plate 327 disengages from the first incomplete gear 332, the first incomplete gear 332 continues to rotate clockwise, and the third sliding rod 328 stops moving. Continuing to start the sixth motor, the third incomplete gear 348 begins to mesh with the first gear 347, which can drive the first gear 347 to rotate, and then drive the wire winding shaft 344 to rotate, so that the rope 342 can be wound. After winding until the rope 342 is straightened, the sixth motor is turned off.

[0074] S2: The patient takes the position

[0075] The patient lies on the hospital bed in a comfortable position, and only needs to ensure that the puncture site to be punctured is exposed to the outside world.

[0076] S3: Adjust the position of the positioning and guiding device 3

[0077] By starting the fifth motor 357, control the positioning and guiding device 3 to move within the track 21, and move the positioning and guiding device 3 to a position convenient for puncture. When moving to the corner of the track 21, start the fourth motor 355 to control the second gear 358 to rotate 90°, so that the second gear 358 meshes with the first rack 22 or the second rack 23 adjacent to the previous moving position. Through the cooperation and adjustment of the first cylinder 31, the first motor 33, the second motor 36, the second cylinder 37 and the third motor 310, the insertion end of the guide wire 4 is aligned with the puncture site to be punctured.

[0078] S4: Perform puncture

[0079] Start the sixth motor again to control the first incomplete gear 332 to rotate clockwise, thereby driving the second incomplete gear 336 to rotate and the third incomplete gear 348 to rotate. At the same time, the second incomplete gear 336 starts to mesh with the fourth rack 335, and the third incomplete gear 348 starts to mesh with the first gear 347, so that the second connecting plate 317 moves towards the puncture site side of the patient, thereby driving the clamping plate 320 to move, and thus pulling the guide wire 4 clamped between the two clamping plates 320 towards the puncture site of the patient. At the same time, while pulling the guide wire 4, the first gear 347 drives the winding shaft 344 to rotate, and can wind one end of the rope 342. During the process of winding the rope 342, the clamping member is pulled to move towards the first connecting plate 312 side, so as to ensure that both ends of the guide wire 4 move simultaneously, so that the guide wire 4 is as straight as possible during the pulling process, avoiding bending or knotting during the pulling process of the guide wire 4 and affecting subsequent pulling, and also preventing the guide wire 4 from protruding from the placement box 311 and affecting the overall appearance of the positioning device.

[0080] After the teeth of the first incomplete gear 332 start to disengage from the third rack 330, the second spring 322 begins to contract, and the two clamping plates 320 move away from each other to loosen the guide wire 4. At the same time, the second drive bar 326 is pushed towards the L-shaped connecting plate 327. As a result, the third sliding rod 328 is squeezed by the second drive bar 326 and moves towards the L-shaped connecting plate 327, causing the bump 352 to disengage from the fixed bar. Under the elastic force of the fifth spring 351, the latch engages with the first gear 347 to limit the first gear 347, thereby preventing the winding shaft 344 from reversing. Then, the second incomplete gear 336 starts to disengage from the fourth rack 335, and the first spring 318 begins to extend, pulling the second connecting plate 317 and the clamping plate 320 back to their initial positions. When the second incomplete gear 336 engages with the fourth rack 335 again, the next round of traction is initiated.
