Technical Field

[0001] The utility model relates to the field of medical instruments, and in particular to a ureteroscope. Background Art

[0002] Urinary tract stones are a common disease in urology. The main treatment method is ureteroscopic laser lithotripsy. The laser reaches the stone site through the working channel of the ureteroscope, and the lithotripsy is performed under visual environment through the ureteroscope.

[0003] During laser lithotripsy, the laser releases a large amount of heat, which, if not effectively controlled, may cause thermal damage to the ureter and other surrounding tissues. Thermal damage may cause inflammation, edema, or even ulcers of the ureteral wall, increasing the risk of postoperative complications such as bleeding, infection, or scar formation. In severe cases, it may have a negative impact on the normal function of the ureter, including ureteral stenosis, dysfunction, or other long-term complications.

[0044] The flexible ureteroscope provided in the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0045] See also Figure 1 to Figure 7 The utility model provides a flexible ureteroscope, which includes an operating handle 200 , a mirror body 100 and a temperature measuring device 300 .

[0046] The scope body 100 includes a tip portion 110, a bending portion 120, and an insertion portion 130 which are sequentially connected from the head end to the tail end, the tail end of the insertion portion 130 is connected to the operating handle 200, and the head end of the insertion portion 130 is connected to the tip portion 110 through the bending portion 120. The tip portion 110 may be a columnar body made of a biocompatible hard material, and may be made of a stainless steel material.

[0047] The tip 110 is provided with a micro camera 141, an illuminating lamp 142 and an operation channel outlet 143. Two illuminating lamps 142 can be provided and symmetrically arranged. The insertion portion 130, the bending portion 120 and the tip 110 are provided with a video line channel, an illuminating line channel and an operation channel.

[0048] A video cable is passed through the video cable channel, one end of the video cable is connected to the micro camera 141, and the other end of the video cable passes through the operating handle 200 to the outside of the operating handle 200 for connection with a display device.

[0049] The lighting line is passed through the lighting line channel, one end of the lighting line is connected to the lighting lamp 142 in a one-to-one correspondence, and the other end of the lighting line is passed through the operating handle 200. A power supply component is provided in the operating handle 200, and the lighting line is connected to the power supply component. A lighting switch is provided outside the operating handle 200 to control the conduction or disconnection of the lighting line and the power supply component.

[0050] One end of the operation channel is connected to the operation channel outlet 143, and an operation channel entrance is provided on the operation handle 200, and the operation channel entrance is connected to the operation channel. When performing laser lithotripsy, the laser device can extend into the front end of the tip portion 110 through the operation channel entrance, the operation channel and the operation channel outlet 143, and then extend to the outside of the tip portion 110.

[0051] In the flexible ureteroscope provided by the present invention, a temperature measuring channel 144 is further provided in the insertion portion 130, the bending portion 120 and the front end portion 110, and the temperature measuring device 300 is inserted into the temperature measuring channel 144. The front end of the temperature measuring device 300 is the temperature measuring end, and the rear end of the temperature measuring device 300 is the driving end. The temperature measuring end is located in the front end portion 110, and the driving end passes through the temperature measuring channel 144 and enters the operating handle 200.

[0052] A telescopic driving mechanism is provided on the operating handle 200, and the driving end of the temperature measuring device 300 is connected to the telescopic driving mechanism in the operating handle 200. The telescopic driving mechanism can drive the temperature measuring device 300 to move in the temperature measuring channel 144 to achieve the effect of the temperature measuring end entering and exiting the mirror body 100. Specifically, the telescopic driving mechanism can drive the temperature measuring end of the temperature measuring device 300 to extend to the outside of the front end portion 110, or drive the temperature measuring end of the side temperature measuring device to retract into the front end portion 110.

[0053] During operation, the operator first drives the scope 100 into the cavity of the urinary system through the operating handle 200, and under the guidance of the video image provided by the micro camera 141, the operator moves the tip 110 of the scope 100 to the affected area. Before the operator operates the scope 100 to move in the cavity of the urinary system, the operator operates the telescopic drive mechanism to retract the temperature measuring end of the temperature measuring device 300 into the tip 110 to prevent damage to the inner wall of the cavity during movement and to prevent the temperature measuring device 300 from hindering the movement and turning of the tip 110.

[0054] When the tip 110 reaches the affected area, the mirror body 100 stops moving, and the operator inserts the laser device into the operating channel. The laser emitting end of the laser device extends to the outside of the mirror body 100 through the operating channel outlet 143 to perform laser lithotripsy on the stones in the affected area.

[0055] Before performing laser lithotripsy, the operator operates the telescopic drive mechanism to extend the temperature measuring end of the temperature measuring device 300 to the outside of the mirror body 100. The temperature measuring end is used to detect the temperature of the surrounding environment or surrounding tissue. The operator can observe the temperature parameters sent back by the temperature measuring device 300 at any time. The operator can control the energy output and action time of the laser according to the temperature parameters to prevent thermal damage to the surrounding tissue.

[0056] In some embodiments of the present invention, the length of the temperature measuring end is 1 cm, 1.5 cm or 2 cm.

[0057] In some embodiments of the present invention, the telescopic drive mechanism may at least include a linear drive mechanism or a rotational drive mechanism.

[0058] In a specific embodiment, the telescopic driving mechanism is a linear driving mechanism, which includes a slide groove 411 and a slider 412 . The slide groove 411 is arranged on the operating handle 200 , and the slider 412 is slidably connected to the slide groove 411 .

[0059] The slider 412 may be disposed outside the operating handle, and one end of the slider 412 extends into the interior of the operating handle 200 for connection with the driving end of the temperature measuring device 300 .

[0060] During use, the operator pushes the slider 412 to move in the slide groove 411 , thereby driving the temperature measuring device 300 to slide along the temperature measuring channel 144 to achieve the effect of the temperature measuring end entering and exiting the front end 110 .

[0061] Furthermore, a linear telescopic device may be provided on the operating handle 200, the fixed portion of the linear telescopic device is connected to the operating handle 200, and the telescopic portion of the linear telescopic device is connected to the slider 412. When the linear telescopic device is extended, the slider 412 may be driven to move, thereby driving the temperature measuring device 300 to move in the temperature measuring channel 144, so that the temperature measuring end of the temperature measuring device 300 extends to the outside of the front end 110. When the linear telescopic device is retracted, the slider 412 may be driven to move, thereby driving the temperature measuring device 300 to move in the temperature measuring channel 144, so that the temperature measuring end of the temperature measuring device 300 is retracted to the inside of the front end 110.

[0062] For example, the linear telescopic device may be an electric push rod 413 or the like.

[0063] It should be noted that when a linear telescopic device is provided, the linear telescopic device and the slider 412 can both be provided inside the operating handle 200, and an operating button 500 can be provided outside the operating handle 200. The operating button 500 includes an extension button and a retraction button. The operator can control the extension and retraction of the linear telescopic device by pressing different buttons, thereby controlling the temperature measuring end to extend out of the front end or to retract into the front end.

[0064] In another specific embodiment, the telescopic drive mechanism is a rotary drive mechanism, which includes a rack 421, a gear 422 and a rotating device. The rack 421 is arranged inside the operating handle 200 and is slidably connected to the operating handle 200, and the sliding direction is along the extension direction of the rack 421. The gear 422 is rotatably connected to the operating handle 200, and the gear 422 is meshed and transmission-connected with the rack 421. The rotating device is arranged on the operating handle 200 and is transmission-connected with the gear 422. The temperature measuring device 300 is connected to the rack 421.

[0065] When in use, the rotating device drives the gear 422 to rotate, and the gear 422 drives the rack 421 to move linearly, thereby driving the temperature measuring device 300 to move along the temperature measuring channel 144 to achieve the effect of the temperature measuring end of the temperature measuring device 300 entering and exiting the front end 110.

[0066] The rotating device may be a rotating handle 423, which can be used to manually drive the gear 422 to rotate. Alternatively, the rotating device may be a rotating motor 424, which can drive the gear 422 to rotate forward or reversely.

[0067] It should be noted that when the rotating device is a rotating handle 423, the operating end of the rotating handle 423 needs to be arranged outside the operating handle, and the rotating end of the rotating handle 423 is connected to the gear transmission inside the operating handle.

[0068] When the rotating device is a rotating motor 424, the rotating motor 424, the gear 422 and the rack 421 are all arranged in the operating handle 200, and an operating button 500 is arranged on the outside of the rotating handle 423. The operating button 500 includes a forward button and a reverse button. The operator controls the rotating motor 424 to rotate forward or reverse by pressing different operating buttons 500, and then drives the gear 422 to drive the rack 421 forward or backward, thereby finally realizing the extension and retraction of the temperature measuring end.

[0069] In some embodiments of the present invention, a display screen 600 is further included. The display screen 600 is connected to the temperature measuring device 300. The display screen 600 can be used to display the temperature parameters detected by the temperature measuring device 300.

[0070] During the operation, the operator cannot always stare at the temperature parameters on the display screen 600. When the operator does not observe the temperature parameters, there is still a risk of excessive temperature causing thermal damage to surrounding tissues. Therefore, the ureteroscope provided by the utility model is also provided with an alarm device, which is connected to the temperature measuring device 300. The alarm device can preset a temperature warning value. When the temperature parameter detected by the temperature measuring device 300 reaches the temperature warning value, the alarm device sends an alarm message to remind the operator that the temperature is too high.

[0071] For example, the alarm information may be vibration information, light information, or sound information.
