The device is intended for abortions in young or middle-aged adults, but is limited to use in the operating room
[0004] Similar products appearing on the foreign market, the tube at the front is usually a plastic tube with only a liquid inlet channel but no liquid outlet channel, and it cannot attract the uterine cavity tissue out.
[0005] Currently, there is no hysteroscopy suitable for postmenopausal elderly women to perform uterine cavity examination in outpatient clinics.

Embodiment 1
[0030] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 As shown, an ultra-thin single-channel electronic hysteroscope with negative pressure function includes a cylinder 10 , and a handle 20 is sheathed on the rear end of the cylinder 10 .
[0031] The handle 20 is provided with a plurality of clamping blocks 22 for fixing the cylinder, and the clamping blocks are respectively arranged on both sides of the cylinder.
[0032] The cylinder body 10 is a single-channel straight pipe, the outer diameter of the cylinder body is not greater than 4mm; the wall thickness of the cylinder body is not greater than 0.13mm. The material of the barrel is stainless steel.
[0033] The front end of the barrel 10 is fixed with an image acquisition end 30 , and the image acquisition end 30 closes the front end of the barrel 10 . The outer diameter of the image collection end 30 is not larger than the outer diameter of the barrel.
[0034] The outer wall of the barrel 10...
Embodiment 2
[0057] Such as Image 6 , Figure 7 , Figure 8 with Figure 9 , the difference between this embodiment and Embodiment 1 is only the light source module. Since other components are the same as those in Embodiment 1, details are not repeated here.
[0058] In this embodiment, the light source module is an LED light 32, and the number of the LED light is one or two. The LED light is arranged around the lens module, and the LED light is connected to the flexible circuit board.
[0059] Such as Figure 8 As shown, there is one LED lamp 32 . Such as Figure 9 As shown, there are two LED lamps 32 . Due to the limited area of the front face of the graphics acquisition terminal, the size of the LED lamp when there are two LEDs is much smaller than the size of the LED when there is one LED. When there are two LED lights, the two LED lights are respectively arranged on both sides of the lens module, so that better illumination can be obtained within the field of view of the le...

Abstract
The invention discloses an electronic hysteroscope with a superfine single channel with the negative pressure function. The electronic hysteroscope comprises a cylinder. The rear end of the cylinder is sleeved with a handle. The cylinder is a single-channel straight pipe, and the outer diameter of the cylinder is not larger than 4 mm; the wall thickness of the cylinder is not larger than 0.13 mm;an image collecting end is fixedly arranged at the front end of the cylinder, and the front end of the cylinder is closed by the image collecting end; the outer diameter of the image collecting end isnot larger than the outer diameter of the cylinder; the outer wall of the cylinder is provided with a through hole for enabling a distention solution to flow in and out, a three-way joint is arrangedat the rear end of the cylinder, and the three-way joint comprises a first connector, a second connector and a third connector; a control switch is arranged on the three-way joint. The hysteropscopeis applicable to uterine cavity inspection on postmenopausal old women at hospital outpatient clinics, is convenient to operate, has the advantage of being high in inspection speed, has the distentionfunction, has the negative pressure suction function and completely meets the requirement for inspection at the hospital outpatient clinics.
Description
technical field [0001] The invention relates to gynecological medical instruments, in particular to an ultrafine single-channel electronic hysteroscope with negative pressure function. Background technique [0002] The hysteroscope currently used in outpatient clinics in hospitals is suitable for performing uterine examinations on young or middle-aged adult women. In postmenopausal elderly women, the cervix shrinks and the uterine cavity is narrow. At present, the hysteroscope used in outpatient clinics in hospitals cannot enter the uterine cavity of postmenopausal elderly women due to the large outer diameter of the front part of the hysteroscope. [0003] In addition, in the existing visible abortion uterine cavity tissue suction system, the cylinder at the front end is generally curved, and the cylinder is usually distributed in double chambers. The external diameter of the cylinder is relatively large, usually about 10mm, and its material is plastic or metal. The wall ...
