Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a novel flexible endoscope. Background Technology

[0002] Currently, with the increasing prevalence of endoscopic technology in medicine, especially in the treatment of urinary system stones, lithotripsy is performed under endoscopic visualization. Stones broken up by laser or other energy are then suctioned out of the body through specific instrument channels or retrieved using a stone retrieval basket, thus completing the treatment. However, most flexible endoscopes currently available for ureteral stone treatment are bidirectionally curved and cannot achieve multidirectional curvature. When dealing with stones in the lower calyx or other locations, the operator needs to adjust their hand or body to a specific angle to capture the image of the stone under bidirectional curvature. Sometimes the angle adjustment is particularly large, which consumes too much physical strength for the operator and reduces efficiency. In view of this, we propose a new type of flexible endoscope. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example:

[0033] Please see Figure 1-10 A novel flexible endoscope includes a body 2, which includes a working part 21 and an operating part 22. The working part 21 includes a woven mesh segment 211 and a spring segment 214 connected to each other, and an outer sleeve 212 is fitted over the woven mesh segment 211 and the spring segment 214. The spring segment 214 is located near the operating part 22, and the woven mesh segment 211 is connected to the end of the spring segment 214 away from the operating part 22. The main function of the woven mesh segment 211 is to prevent the working part 21 from breaking when the endoscope is bent.

[0034] like Figure 8As shown, the operating unit 22 includes an adjustment assembly and multiple directional wires 215. The directional wires 215 are parallel to the extending direction of the operating unit 22. The multiple directional wires 215 are arranged in a ring inside the woven mesh segment 211 and the spring segment 214. The adjustment assembly is connected to the ends of the multiple directional wires 215, and the other end of each directional wire 215 is connected to the end of the woven mesh segment 211 away from the spring segment 214. The adjustment assembly can rotate 360°. By rotating the adjustment assembly, the multiple directional wires 215 are displaced respectively. The magnitude of the displacement of each directional wire 215 determines the bending direction of the working unit 21, thereby controlling the bending of the working unit 21 in different directions, thus realizing the function of 360° rotation and bending of the endoscope. This solves the problem in the prior art that the surgeon needs to adjust their hand or body to a specific angle to capture the required image, while improving surgical efficiency.

[0035] In this application, such as Figure 5-7 As shown, the woven mesh segment 211 has multiple sequentially arranged snake bones inside, and multiple through holes are opened on the snake bones, through which the directional drawing wire 215 passes. Figure 6 As shown, the directional section 213 is composed of multiple snake-like structures. Each snake-like structure is a metal ring with a twisted angle. Because the metal rings are twisted at a certain angle, there is a gap between adjacent metal rings. Specifically, when a single twisted metal ring is subjected to the tension of the directional wire 215, the gap between the metal rings changes. The direction in which the gap shortens is the final directional bending direction. Since there are a large number of twisted metal rings, the deformation can be accumulated individually to meet the requirements for the degree of directional bending of the endoscope.

[0036] In this application, the operating part 22 also includes a sheath 222, such as Figure 3 As shown, the sheath 222 is connected and fixed to the outer sheath 212; as Figure 8 As shown, the adjustment assembly includes a rocker ball 228 and multiple fixing blocks 227. The rocker ball 228 is movably connected to the sheath 222 and can rotate 360°. The multiple fixing blocks 227 are evenly distributed along the circumference of one end of the inner side of the rocker ball 228. A directional adjustment wire 215 is connected and fixed to the fixing blocks 227. A directional adjustment button 225 is provided at one end of the outer side of the rocker ball 228. The fixing blocks 227 are located inside the rocker ball 228, and the directional adjustment button 225 at one end of the rocker ball 228 extends out of the handle 223. There are at least four directional adjustment wires 215 and four fixing blocks 227. The fixing blocks 227 are evenly distributed and fixed to one end of the rocker ball 228. By rotating the directional adjustment button 225, the rocker ball 228 is rotated.

[0037] like Figure 10As shown in this application, the working section 21 is provided with a working channel 216, which passes through the woven mesh section 211 and the spring section 214, and extends all the way to the head of the working section 21; the sheath 222 is also provided with an injection port 221, and the working channel 216 is connected to the injection port 221.

[0038] In this application, a handle 223 is fixed to the surface of the sheath 222, and a control button 226 is provided on the handle 223. The control button 226 is a photo taking and video recording button. A light source 217 and an imaging module 218 are also provided on one side of the end of the woven mesh segment 211. The control button 226 is electrically connected to the imaging module 218. Pressing the control button 226 once takes a photo, and pressing it for a long time records a video.

[0039] like Figure 1-2 As shown, this application also includes a monitor 1, which is connected to the endoscope 2. The monitor 1 includes a display screen 11, with a wire 13 connected to the display screen 11. A plug 12 is provided at the end of the wire 13. An insertion hole 224 is provided on the operation unit 22, and the plug 12 is connected to the insertion hole 224. The display screen 11 has an external power supply port, which powers the endoscope. The plug 12 and wire 13 transmit the actual image captured by the endoscope 2 to the display screen 11 for display. The display screen 11 has the function of displaying images.

[0040] In use, this invention works as follows: The directional button 225 rotates the rocker arm 228, causing it to rotate 360°. Since the directional button 225 can rotate 360°, this also causes the rocker arm 228 to rotate 360°. Because the fixing block 227 is fixed to one end of the rocker arm 228, it also rotates 360°, further causing the directional tension wire 215 to rotate. This tension is then transmitted to the directional section 213. The directional section 213 consists of multiple metal rings twisted at a certain angle, with gaps between adjacent twisted rings. As each twisted metal ring is pulled by the directional tension wire 215, the gaps between adjacent rings change. The direction of the shortening gap is the final directional bending direction. Because there are many twisted metal rings, the deformation accumulates to meet the directional bending requirements of the endoscope. Through these operations, this endoscope can achieve a 360° directional bending function at its tip.

[0041] Furthermore, under the action of the light source 217 and the imaging module 218, the endoscope can take pictures and record videos in real time through the control button 226; in addition, the endoscope has a working channel 216, which allows for the insertion of therapeutic instruments through the working channel 216 under real-time observation of the endoscope, so as to treat the patient in real time and improve work efficiency.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
