2. The uterine cavity endoscope with the water valve and the instrument channel as claimed in claim 1, wherein the diameter of the instrument channel is 4.1 mm.

3. The hysteroscope having a self-contained water valve, instrument channel, as recited in claim 1, wherein said water valve is in 45 degree angular communication with the instrument tube.

Technical Field

The invention relates to the field of medical instruments, in particular to a uterine cavity endoscope with a water valve and an instrument channel.

Background

The original uterine cavity endoscope can be operated only by matching with an endoscope sheath and an operator, an instrument channel on the operator is small, and only instruments with the diameter smaller than 3mm can be passed through, so that limitation exists, and although the instruments can complete the operation with high precision, the defects of insufficient fastness and the like exist, and certain operation requirements cannot be met. And after the original uterine cavity endoscope is matched with the manipulator and the instrument is arranged in the instrument channel, the operation of the instrument can interfere with a cable behind the optical interface.

Disclosure of Invention

In order to solve the technical problem, the invention designs a uterine cavity endoscope with a water valve and an instrument channel.

The invention adopts the following technical scheme:

the utility model provides a from palace cavity endoscope of taking water valve, apparatus passageway, leaded light bundle plug, the mirror body, the eyepiece cover, apparatus valve and water valve, mirror pipe and apparatus pipe set up side by side, apparatus intraductal setting up apparatus passageway, leaded light bundle plug and eyepiece cover set up on the mirror body, leaded light bundle plug and eyepiece cover communicate with the mirror pipe through the mirror body, eyepiece and mirror pipe are not on a straight line in the eyepiece cover, but are 45 degrees contained angles intercommunication, eyepiece cover and leaded light bundle plug lie in the mirror body with one side, apparatus valve and water valve intercommunication apparatus intraductal apparatus passageway of apparatus, apparatus valve direction and apparatus pipe are on same straight line. A mirror tube: the lens tube is internally provided with optical fibers and lenses and is used for transmitting light emitted by the cold light source to a human body and transmitting images received in the human body to the camera system. An instrument tube: for creating a passage for the instrument to enter the body and expand the uterus. Light guide bundle plug: the cold light source is used for connecting the light guide beam and receiving the light emitted by the cold light source. A mirror body: the mirror body is used for installing each part and integrating the parts together. An eyepiece cover: the optical interface is used for connecting and transmitting the received image to the camera system. An instrument valve: a valve is established for the passage of instruments into the body. A water valve: it is used for connecting a medical pressurizer, expanding the uterus and cleaning instruments.

Preferably, the instrument channel has a diameter of 4.1 mm.

Preferably, the water valve is in 45-degree angle communication with the instrument tube.

The invention has the beneficial effects that: the uterine cavity endoscope provided by the invention is provided with a water valve and an instrument channel, can complete the operation without matching with an endoscope sheath and an operator, has the instrument channel diameter of 4.1mm, can pass instruments with the diameter larger than 3mm, and can meet the requirements of most operations. The eyepiece and the lens tube are not on the same straight line, but form an included angle of 45 degrees, are on the same side with the light guide bundle plug, and the length of the eyepiece is lengthened, and after the eyepiece cover is matched with the optical interface, the interference phenomenon of cables behind the optical interface during the operation of instruments is avoided.
