Description

Technical Field

[0001] The utility model relates to a handle device for anus examination under an endoscope, belonging to the field of anorectal examination equipment. Background Art

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has an image sensor, optical lens, light source, mechanical device, etc. It can enter the stomach through the mouth or other natural orifices into the body. Endoscopes can be used to see lesions that X-rays cannot show, so they are very useful to doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the rectum and develop the best treatment plan based on this.

[0003] The current endoscope includes two components, one is a video monitoring device, an endoscope lens and a connecting line; for example, the patent application number is CN201920009899.1, and the patent application name is an electronic endoscope, which discloses an electronic endoscope video monitoring device, an endoscope lens and a connecting line. The electronic endoscope video monitoring device and the endoscope lens are electrically connected through a connecting line, and an endoscope lens is fixedly connected to the side wall of the endoscope lens away from the end of the connecting line, and a stop block is provided on the side of the endoscope lens close to the endoscope lens, and a storage groove corresponding to the position of the stop block is provided on the side wall of the endoscope lens away from the end of the connecting line, so that the detected image display is no longer blurred or black, avoiding damage to the inner cavity, improving the accuracy of inspection and diagnosis, and improving detection efficiency.

[0004] However, in actual operation, the following problems still exist:

[0005] The end of the endoscope is inserted deep into the internal organs of the human body. In addition to the light source generated by the endoscope's video monitoring device and the endoscope lens, there is no conversion port to connect to other cold light sources. Therefore, when the endoscope camera system takes pictures, there is not enough light source to observe the lesion.

[0006] Therefore, the utility model provides a handle device for anal examination under an endoscope, which can guide a light source and facilitate observation and photographing of lesions. Utility Model Content

[0007] The utility model provides a handle device for anal examination under an endoscope, which can effectively solve the above problems.

[0008] The utility model is achieved in this way:

[0009] A handle device for anal examination under an endoscope comprises a handle, an optical bayonet, a conversion port, and a disposable anal examination mirror. The handle comprises a horizontal portion and an inclined portion. One end of the horizontal portion is provided with an inclined portion at a preset angle A, and the other end is horizontally mounted with an optical bayonet. A disposable anal examination mirror is mounted on the free end of the optical bayonet through a conversion port for guiding a light beam. The preset angle A described herein is 50°-85°.

[0010] As a further improvement, the conversion port includes a connecting pipe and a beam tube vertically fixed in the middle of the connecting pipe by a threaded connection, and the connecting pipe is connected to the beam tube.

[0011] As a further improvement, the beam tube is a cylinder with a metal sleeve wrapped on the outside, the middle of the cylinder is an optical interface, and also includes a core inserted in the optical interface.

[0012] As a further improvement, the diameter of the first end surface of the connecting tube close to the disposable anus inspection mirror is larger than the diameter of the second end surface.

[0014] As a further improvement, an inclined surface is provided on the inner wall of the connecting pipe close to the optical bayonet.

[0015] As a further improvement, a trigger is rotatably connected to the horizontal portion and the inclined portion of the handle at an angle A, and a micro switch is arranged inside the handle opposite to the trigger;

[0016] Circuit board, the micro switch is electrically connected to the circuit board installed on the handle.

[0017] The beneficial effects of the utility model are:

[0018] ① The utility model adds an optical bayonet to guide the external cold light source into the optical bayonet of the handle and the disposable anus examination mirror. The disposable anus examination mirror is placed in the anorectum of the human body to facilitate the observation of muscle tissue or lesions in the anorectal position.

[0019] ② The beam tube of the conversion port of the utility model is connected to the external cold light source, and utilizes the total reflection of light from the optically dense medium into the optically sparse medium, and completely guides the light into the connecting tube, and then transmits it to the optical bayonet and the disposable anal inspection mirror.

[0020] ③ The utility model pulls the trigger to make the micro switch work, opens and closes the circuit board, and controls the optical bayonet to take pictures or control the opening and closing of the device through the circuit board, which is easier to operate.

The free end of the optical bayonet 20 is mounted with the disposable anal examination mirror 40 through the conversion port 30 for guiding the light beam. The preset angle A described here is 50°-85°.

[0031] The utility model adds an optical bayonet 20 to guide the external cold light source into the optical bayonet 20 of the handle 10 and the disposable anus examination mirror 40. The structure and principle of the disposable anus examination mirror 40 are detailed in the patent application titled "A disposable anoscope for electronic anorectal examination mirror". The disposable anus examination mirror 40 is a disposable device placed in the human anus and rectum for auxiliary examination, which is convenient for observing muscle tissue or lesions in the anorectal position.

[0032] The conversion port 30 includes a connecting pipe 301 and a beam pipe 302 vertically fixed in the middle of the connecting pipe 301 by threaded connection, and the connecting pipe 301 and the beam pipe 302 are connected.

[0033] Furthermore, the beam tube 302 is a cylinder 322 with a metal sleeve 321 wrapped around the outside, and the middle of the cylinder 322 is an optical interface 323, and also includes a core located in the optical interface 323, which is not shown in the figure;

[0034] The beam tube 302 of the conversion port 30 is connected to an external cold light source, and utilizes the total reflection of light from a denser medium into a less dense medium, and guides the light completely into the connecting tube 301 , and then transmits it to the optical mount 20 and the disposable anal inspection mirror 40 .
