Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel guidewire storage device for endoscopes. Background Technology

[0002] Digestive endoscopy plays a crucial role in the diagnosis of early gastrointestinal tumors and diseases of the bile ducts and pancreas. It allows direct observation of structural changes in the digestive tract wall; for minute mucosal lesions, optical magnification and microscopic staining can reveal subtle structural changes; with an attached laser confocal microscope, the microstructure of the digestive tract mucosa can be obtained, allowing direct observation of pathological changes; with an attached ultrasound scanning probe, the size, tissue origin, and depth of invasion of lesions in the digestive tract wall can be diagnosed, while also obtaining clearer ultrasound images of the bile ducts, pancreas, and other digestive organs; and with the aid of X-ray contrast imaging, radiographic images of the bile ducts and pancreatic ducts can be obtained to diagnose diseases of the bile ducts and pancreas.

[0003] During digestive endoscopy, multiple guidewires are used simultaneously. The guidewire tips enter the organ through a common endoscopic channel, while the guidewire tails are coiled separately and placed outside the body. This means that the assistant not only has to constantly monitor the manipulation of the guidewire tips but also needs to grasp the remaining coiled sections, which affects the assistant's work.

[0031] As described in the background section, multiple guidewires are used simultaneously during digestive endoscopy. The guidewire tips enter the organ through a common endoscopic channel, while the guidewire tails are coiled separately and placed outside the body. This means that the assistant not only has to constantly monitor the manipulation of the guidewire tips but also needs to grasp the remaining coiled sections, which in turn affects the assistant's work.

[0032] To solve this technical problem, this utility model provides a novel guidewire storage device for endoscopes, which is used in medical assistance.

[0033] For details, please refer to Figures 1-3 The new type of guidewire storage equipment for endoscopes specifically includes:

[0034] The winding frame 1 has a winding rod 4 vertically rotatably connected inside the winding frame 1. A winding roller 5 is sleeved on the outside of the winding rod 4. A limit component is provided on the outside of the winding roller 5.

[0035] The drive box 2 is located at the lower end of the winding frame 1. The drive box 2 contains the same number of winding motors 3 as the winding rods 4. The output end of the winding motor 3 is fixedly connected to the winding rods 4 at the corresponding positions.

[0036] The wire guide hook 6 is located at the upper part of the take-up frame 1. The wire guide hook 6 includes a wire guide traction rod 9. The lower end of the wire guide traction rod 9 extends into the interior of the take-up frame 1. A wire guide traction ring 10 is fixed at the lower end of the wire guide traction rod 9. The wire guide traction ring 10 is located on the side of the take-up roller 5. The wire guide hook 6 can slide vertically.

[0037] The novel endoscope guidewire storage device provided by this utility model, through the combined design of multiple structures, enables the device to easily wind up the guidewire, and multiple guidewires can be wound up by multiple winding rollers 5, thereby effectively freeing the assistant's hands and allowing the assistant to focus on the operation of the guidewire head section.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] Example 1:

[0040] Please refer to Figures 1-3 A novel guidewire storage device for endoscopes, comprising:

[0041] The take-up frame 1 has a take-up rod 4 vertically rotatably connected inside. A take-up roller 5 is sleeved on the outside of the take-up rod 4. When the take-up rod 4 rotates, it can drive the take-up roller 5 to rotate synchronously, thereby realizing the winding operation of the guide wire through the rotating take-up roller 5. A limit component is provided on the outside of the take-up roller 5. In order to limit one end of the guide wire and facilitate the winding of the guide wire when the take-up roller 5 rotates, the limit component includes a guide wire fixing frame 7. The guide wire fixing frame 7 is fixedly connected to the take-up roller 5. A gap is provided on the inner side of the guide wire fixing frame 7 for the guide wire to pass through. A guide wire fixing knob 8 is threadedly connected to the end of the guide wire fixing frame 7 away from the take-up roller 5. One end of the guide wire fixing knob 8 extends into the gap.

[0042] The drive box 2 is located at the lower end of the take-up frame 1. Inside the drive box 2 are the same number of take-up motors 3 as the take-up rods 4. The output ends of the take-up motors 3 are fixedly connected to the corresponding take-up rods 4. Therefore, in use, starting the take-up motors 3 drives the corresponding take-up rods 4 and take-up rollers 5 to rotate, thereby achieving automatic winding of the guide yarn. The take-up motors 3 can be commercially available and known models. For those skilled in the art, the control buttons controlling the operation of the forward and reverse motors via the control circuit, and the battery holder supplying power to the forward and reverse motors via the power supply circuit, are conventional technical means, and their principles will not be described in detail here.

[0043] The wire guide hook 6 is located at the upper part of the take-up frame 1. The wire guide hook 6 includes a wire guide traction rod 9. The lower end of the wire guide traction rod 9 extends into the interior of the take-up frame 1. A wire guide traction ring 10 is fixed at the lower end of the wire guide traction rod 9. The wire guide traction ring 10 is located on the side of the take-up roller 5. The wire guide hook 6 can slide vertically.

[0044] Furthermore, the upper end of the take-up frame 1 is also provided with a drive assembly, which is used to drive the guide hook 6 to move up and down. When the take-up roller 5 takes up the guide wire, the drive assembly can drive the guide hook 6 to move up and down reciprocally, thereby guiding the guide wire through the guide hook 6, so that the guide wire can be evenly wound to the outside of the take-up roller 5.

[0045] In summary, when using the device, connect an external power source, pass one end of the guide wire through the guide wire traction ring 10 in the guide wire hook 6, and extend it into the inner side of the guide wire fixing bracket 7 in the limiting assembly. Fix the end of the guide wire by tightening the guide wire fixing knob 8. Start the winding motor 3 to drive the winding rod 4 and the winding roller 5 to rotate synchronously, thereby winding the guide wire onto the surface of the winding roller 5. During the winding process, the drive assembly drives the guide wire hook 6 to move up and down reciprocally, thereby guiding the guide wire through the guide wire hook 6, so that the guide wire can be evenly wound onto the outside of the winding roller 5.

[0046] Example 2:

[0047] The novel endoscopic guidewire storage device provided in Example 1 has been further optimized, specifically, as follows: Figures 3-7 As shown, the drive assembly includes a fixed support plate 14, the lower end of which is fixedly connected to the winding frame 1. A traction drive disc 12 is fixed to one side of the upper end of the fixed support plate 14. A traction drive block 13 is fixed to the side of the traction drive disc 12 away from the fixed support plate 14. A traction frame 11 is fixed to the top of the wire guide hook 6. The traction drive block 13 extends into the traction frame 11. A follower wheel 16 is rotatably connected to the other side of the fixed support plate 14. The follower wheel 16 is fixedly connected to the traction drive disc 12.

[0048] Furthermore, the drive assembly also includes a fixed support plate 2 17, on one side of which a drive wheel 19 is rotatably connected. The drive wheel 19 and the follower wheel 16 are connected by a transmission belt 20. A drive motor 18 is fixed on the other side of the fixed support plate 2 17, and the output end of the drive motor 18 is fixedly connected to the drive wheel 19.

[0049] In order to guide and limit the movement of the traction frame 11, a vertical plate 15 is fixed at the lower end of the traction frame 11. The vertical plate 15 is arranged parallel to the guide wire hook 6 and is vertically slidably connected to the winding frame 1. Through the connection and cooperation between the vertical plate 15 and the winding frame 1, the traction frame 11 is limited, so that the traction frame 11 can only move up and down.

[0050] With the above structural design, during the winding process of the guide wire, the drive motor 18 is started to drive the drive wheel 19 to rotate synchronously, and then the transmission belt 20 drives the traction drive disk 12 to rotate accordingly. The traction drive block 13 on the outside of the traction drive disk 12 moves inside the traction frame 11, thereby pushing the traction frame 11 to move up and down, thereby driving the guide wire hook 6 below to move up and down.

[0051] Example 3:

[0052] The novel endoscopic guidewire storage device provided in Example 2 has been further optimized, specifically, as follows: Figures 6-7 As shown, the drive assembly also includes an auxiliary wheel 21, which is arranged as two symmetrical guide wheels. Both guide wheels are fixedly connected to the winding frame 1 through a connecting rod. The auxiliary wheel 21 is used to tighten the drive belt 20.

[0053] By tightening the transmission belt 20 with the auxiliary wheel 21, the friction between the transmission belt 20 and the follower wheel 16 can be effectively increased, thereby reducing the slippage phenomenon between the follower wheel 16 and the transmission belt 20.
