Description

Technical Field

[0002] This invention relates to the field of observation endoscope technology, specifically to an observation endoscope and a urethrocystoscope. Background Technology

[0003] Endoscopes, as medical diagnostic devices that are inserted directly into the patient's body through an endoscope structure and used to photograph diseased organs, enable medical personnel to directly and quickly understand the lesion site, thereby improving the success rate of surgery. Additionally, during endoscopic surgery, it is necessary to perform fluid injection and drainage procedures within the body.

[0004] The existing endoscope structure includes a support tube with a generally circular wall. Inside the tube are a camera lens and an optical fiber, used for illumination and image transmission. This existing endoscope structure has the following problems in practical use: 1. Because the observation lens is very thin, when the observation lens moves and bends inside the body, the optical fiber is prone to breakage due to insufficient rigidity of the support tube, which will prevent the device from working properly. Second: In actual use, the observation scope is surrounded by a sheath tube with a water inlet hole. Water return is achieved through the water inlet hole. However, due to the small gap between the sheath tube and the support tube, the water return efficiency is slow. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides an observation endoscope and a urethrocystoscope. The technical problem to be solved is that the observation endoscope in the existing endoscope has poor rigidity and slow water return efficiency during use.

[0006] To solve the above technical problems, in a first aspect, the present invention provides the following technical solution: an observation mirror, including a support tube, wherein an imaging tube is provided inside the support tube; Along the length of the support tube, the tube wall of the support tube is provided with an upper recess and two side recesses, the upper recess is above the shooting tube, and the two side recesses are on both sides of the shooting tube; Inside the support tube, reinforcing ribs are provided between the upper recess and each side recess; Along the length of the support tube, a light guide is also provided inside the tube.

[0007] In one embodiment of the first aspect, the bottom surfaces of the upper recess and the two side recesses are both arc surfaces.

[0008] In one embodiment of the first aspect, the light guide is an optical fiber.

[0009] In one embodiment of the first aspect, the light guide portion is a light guide strip.

[0010] In one embodiment of the first aspect, a camera is installed at the shooting port of the shooting tube.

[0011] Secondly, the present invention also provides a urethrocystoscope, including the above-mentioned observation endoscope, and also including a connector seat; the connector seat includes a connecting part, the connecting part includes a connecting surface, the connecting surface is provided with a connecting port that matches the support tube, the support tube is inserted into the connecting port, the connecting part is surrounded by a sheath tube, and the sheath tube has a water inlet on its wall. An operating port is provided above the connecting port on the connecting surface, and an operating channel is provided inside the connector seat along the direction away from the observation mirror from the operating port.

[0012] In one embodiment of the second aspect, the connecting portion is cylindrical.

[0013] The beneficial effects of this invention compared with the prior art are as follows: Firstly, by setting an upper recess and two side recesses on the wall of the support tube and providing reinforcing ribs between the upper recess and each side recess, the strength of the support tube can be improved and the degree of bending of the support tube during use can be reduced. Secondly, by providing a light guide inside the support tube, supplementary light can be provided through the light guide, so that the image information captured by the camera in the observation mirror can be transmitted without optical fiber, thus making the observation mirror more versatile. Finally, the two side indentations increase the space between the sheath and the support tube, thereby increasing the return water speed and improving the applicability of the urethrocystoscope of the present invention.
