Technical Field

[0001] This utility model relates to a needle-finding catheter fixation device, specifically an interventional radiology catheter fixation device, belonging to the field of radiology catheter fixation technology. Background Technology

[0002] Interventional radiology involves inserting specialized catheters or instruments into the lesion site for diagnostic imaging and treatment under the guidance of medical imaging (X-ray, ultrasound, CT, MRI) through percutaneous puncture or through existing body orifices. Interventional catheter treatments typically involve inserting very long catheters into the body. Due to the length of the catheter, it is necessary to fix the catheter located outside the body to ensure its smooth entry into the body. This process usually requires the use of interventional catheter fixation devices.

[0003] A search revealed Chinese patent CN221808294U, which discloses an interventional radiology catheter fixation device. By using a hinged first and second half-tube, and installing a pin on the second half-tube, the device can be directly fastened to the catheter insertion position, making installation more convenient and quick. Inflating the balloon with an appropriate amount of gas ensures good fixation at both ends of the device, preventing movement. However, the clamping angle of the catheter in this patented product is fixed and cannot be adjusted. For some special patients or surgical scenarios, the catheter insertion angle cannot be adjusted.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 As shown, an interventional radiology catheter fixation device includes a base 1. A vertical plate 401 is located near a corner at one end of the base 1. An auxiliary device 4 is mounted on the vertical plate 401. An adjustment device 3 is mounted on the base 1. The adjustment device 3 includes an adjustment groove 301, a rotating shaft 302, a first retaining ring 303, a lead screw 304, a threaded block 305, a first folding rod 306, a second folding rod 307, a rotating rod 308, and a second retaining ring 309. An adjustment groove 301 is located on the top side of the base 1 away from the vertical plate 401. 01 is equipped with a lead screw 304, and a threaded block 305 is provided on the lead screw 304. A rotating shaft 302 is provided at the end of the adjusting groove 301 away from the vertical plate 401. A first retaining ring 303 is provided at the top of the rotating shaft 302. A first folding rod 306 is provided on the threaded block 305. A second folding rod 307 is provided between the end of the first folding rod 306 away from the threaded block 305 and the bottom end of the rotating shaft 302. A rotating rod 308 is provided at the connection between the first folding rod 306 and the second folding rod 307. A second retaining ring 309 is provided at the top of the rotating rod 308.

[0019] The threaded block 305 is connected to the lead screw 304, the rotating shaft 302 is fixedly connected to the base 1, the second folding rod 307 is rotatably connected to the rotating shaft 302 and the rotating rod 308, the bottom end of the first retaining ring 303 is movably connected to the rotating shaft 302, and the bottom end of the second retaining ring 309 is movably connected to the rotating rod 308.

[0020] According to the above embodiments, it should be noted that: when in use, the adhesive cloth 1 at the bottom of the base 1 is attached to the position where the patient needs to insert the catheter, and the catheter is fixed between the first retaining ring 303 and the second retaining ring 309.

[0021] When faced with special patients or special surgical scenarios, and it is necessary to adjust the insertion angle of the catheter, medical staff take the rotating lever 5, align the rotating lever 5 with the slot position between the groove 402 on the vertical plate 401 and the rotating block 403, and manually rotate the rotating knob 501 to drive the rotating lever 5 to rotate against the rotating block 403.

[0022] At this time, the rotating block 403 rotates, driving the connected connecting rod 404 and the large gear 405 to rotate. The small gear 406, which meshes with the large gear 405, starts to rotate, thereby driving the rotating rod 407, the conveyor belt 408, and the lead screw 304 to rotate. The threaded block 305, which is connected to the lead screw 304 nut, moves left and right on the lead screw 304, thereby causing the angle between the first folding rod 306 and the second folding rod 307, which are folded up and down by default, to change. When the threaded block 305 moves away from the rotating shaft 302, the angle between the first folding rod 306 and the second folding rod 307 increases to form a triangle, and the second retaining ring 309 is lifted, thereby adjusting the angle of the guide tube fixed between the two retaining rings.

[0023] Please see Figure 1-4 As shown, an interventional radiology catheter fixation device includes an auxiliary device 4 comprising a vertical plate 401, a groove 402, a rotating block 403, a connecting rod 404, a large gear 405, a small gear 406, a rotating rod 407, and a conveyor belt 408. The vertical plate 401 has a groove 402 in the middle of its end away from the base 1. The rotating block 403 is located inside the groove 402. The connecting rod 404 is located at the end of the rotating block 403 near the base 1. The large gear 405 is located at the end of the connecting rod 404 away from the rotating block 403. The small gear 406 is located at the bottom of the large gear 405. The rotating rod 407 is located at the end of the small gear 406 near the rotating block 403. The conveyor belt 408 is located between the rotating rod 407 and the end of the lead screw 304.

[0024] The large gear 405 meshes with the small gear 406. The inside of the conveyor belt 408 is meshed with the rotating rod 407 and the end of the lead screw 304. The rotating block 403 is arranged in a star shape. The rotating block 403 is equipped with a rotating lever 5. The end of the rotating lever 5 away from the groove 402 is equipped with a rotating knob 501. The rotating block 403 is located inside the groove 402.

[0025] The top of the base 1 is provided with a color sticker slot 2 near the vertical plate 401. The bottom of the base 1 is provided with adhesive cloth 101 around the perimeter, and the center of the adhesive cloth 101 is provided with breathable mesh cloth 102.

[0026] According to the above embodiments, it should be noted that: different sizes of catheters are used according to different ages. Corresponding color stickers can be placed inside the color sticker slot 2 on the base 1 of the catheter fixing device, so that the two retaining rings can be locked in place for the catheter of the specified size when in use.

[0027] The breathable mesh 102 in the middle of the adhesive tape 101 increases the patient's comfort to some extent.

[0028] In summary, the procedure for using this device is as follows: When using it, attach the adhesive cloth 1 at the bottom of the base 1 to the position where the patient needs to insert the catheter, and fix the catheter between the first retaining ring 303 and the second retaining ring 309.

[0029] When faced with special patients or special surgical scenarios, and it is necessary to adjust the insertion angle of the catheter, medical staff take the rotating lever 5, align the rotating lever 5 with the slot position between the groove 402 on the vertical plate 401 and the rotating block 403, and manually rotate the rotating knob 501 to drive the rotating lever 5 to rotate against the rotating block 403.

[0030] At this time, the rotating block 403 rotates, driving the connected connecting rod 404 and the large gear 405 to rotate. The small gear 406, which meshes with the large gear 405, starts to rotate, thereby driving the rotating rod 407, the conveyor belt 408, and the lead screw 304 to rotate. The threaded block 305, which is connected to the lead screw 304 nut, moves left and right on the lead screw 304, thereby causing the angle between the first folding rod 306 and the second folding rod 307, which are folded up and down by default, to change. When the threaded block 305 moves away from the rotating shaft 302, the angle between the first folding rod 306 and the second folding rod 307 increases to form a triangle, and the second retaining ring 309 is lifted, thereby adjusting the angle of the guide tube fixed between the two retaining rings.

[0031] Different sizes of catheters are used for different ages. Corresponding color stickers can be placed in the color sticker slots 2 on the base 1 of the catheter holder, so that the two retaining rings can be used to lock the catheter of the specified size.

[0032] The breathable mesh 102 in the middle of the adhesive tape 101 increases the patient's comfort to some extent.
