[0025] In order to more clearly describe the technical content of the present invention, further description will be given below in conjunction with specific embodiments.

[0026] The special-shaped tip device of the present invention includes a notch-shaped tip, an image acquisition window, two transmission beam holes and a dual-channel outlet. The image acquisition window is located at the top center of the notch-shaped tip, the two transmission beam holes are respectively located on the upper and lower sides of the image acquisition window, and the dual-channel outlet is located on the left and right sides of the image acquisition window. The plane of the dual-channel outlet is lower than the image acquisition window and the transmission beam hole.

[0027] As a preferred embodiment of the present invention, the two transmission beam holes and the image acquisition window are on the same straight line.

[0028] As a preferred embodiment of the present invention, the dual-channel outlet is a symmetrical double-cutout type, and is symmetrically positioned at 90 degrees to the image acquisition window.

[0029] As a preferred embodiment of the present invention, there are two grooves between the image acquisition window and the two beam transmission holes, which are respectively located on both sides of the image acquisition window.

[0030] As a preferred embodiment of the present invention, the cutout of the dual-channel outlet is an irregular circle.

[0031] The utility model relates to a device with an incision-type double-channel pointed head, which is designed to fully utilize the visualization of the endoscope to accurately position and control the entry into the cavity, and combined with the modified design on the pointed head of the endoscope, achieve the intended purpose of use.

[0032] This utility model is designed to realize the new purpose of positioning and releasing the urethral stent on the basis of endoscopic visualization and precise positioning control. On the basis of the dual channels of the endoscope, one working channel is used to place and release the damping device, and one channel is used to release the lubricating water in front of the damper, and to clean and disinfect the cavity circulation for placing the stent. The damper is fixed on the tip of the endoscope and can freely enter and exit the cavity to find the most suitable position for placing the stent. This ingenious design of the damper fixed on the opposite tip is worthy of being a good utility model design.

[0033] In a specific embodiment of the present invention, a device with a notched dual-channel tip is provided, comprising a dual-channel outlet, a notched tip head, a beam transmission hole and an image acquisition window.

[0034] The image acquisition window on the tip is located at the center of the notched tip's top. The transfer beam apertures are located on either side of the image acquisition window. The dual-channel exits are symmetrically positioned on either side of the image acquisition window, at right angles to the transfer beam apertures. The plane of the dual-channel exits on the notched tip is slightly lower than the image acquisition window and the transfer beam apertures on either side of the image acquisition window. This height difference below the acquisition window allows space for the release device. The dual channels are symmetrical, with two notches, and are aligned at 90 degrees to the image acquisition window.

[0035] The device includes an image acquisition window, a beam transmission aperture, a notched dual-channel tip, and a dual-channel outlet. The notched dual-channel outlet is slightly lower than the image acquisition window and the illumination light transmission aperture. In other words, the tip is a non-planar, irregularly shaped tip.

[0036] The tip is a dual-channel type with symmetrical double cutouts.

[0037] The device also includes an image collection window and symmetrical double-transmitting light transmission holes, and the light transmission holes and the image collection window are on the same straight line.

[0038] There are two symmetrical grooves between the transmission beam holes distributed on both sides of the image acquisition window, which are the fixing grooves for the device used to release the bracket.

[0039] The incision is the working channel for entering and exiting the device. The purpose of the incision is to fix and release the fixed bracket, while also allowing for more water to flow out under the control of the back end. The incision here refers to the beveled cuts on both sides of the tip, just at the dual-channel exit point.

[0040] The damper is fixed on the pointed end of the anisotropic cut, and the protruding edge portion is used to prevent rear objects from falling.

[0041] The groove of the non-planar tip head is used to place a damping device for releasing the bracket. When not released, the damping device is fixed on the tip head to block the spring bracket at the rear. When the bracket needs to be released, the damping device is pushed out by connecting the guide wire in the working channel to achieve the function of releasing the bracket.
