Problems solved by technology

[0003] It should be pointed out that the liquid in the working pipeline of the existing all-round hysteroscope often leaks a lot when the instrument is inserted, replaced or missing, which affects the normal use of the all-round hysteroscope.
The leak-proof structure of the universal hysteroscope currently on the market is usually unable to prevent the leakage of liquid during the process of entering and pulling out the working instrument, which will inevitably lead to a decrease in the pressure in the uterine cavity, and the hysteroscope cannot be used normally. ; In addition, the existing all-round hysteroscope is often not suitable for instruments with different instrument tips, and cannot achieve a better anti-leakage effect

Embodiment 1

[0044] Reference manual attached Figure 1 to Figure 4 , the omnipotent hysteroscope provided by the present invention is described, and the channel sealing mechanism of the omnipotent hysteroscope provided by the present invention can be better when the working instrument 3 passes through, the working instrument 3 is replaced, and the working instrument 3 is missing. Reduce the outflow of liquid in the working pipeline, and keep the liquid pressure in the working pipeline in the range of 80-120mmHg during the use of the hysteroscope.

[0045] Reference manual attached figure 1 and figure 2, The omnipotent hysteroscope provided by the present invention includes a hysteroscope main body 1 , a channel sealing mechanism 2 and a working instrument 3 . The hysteroscope main body 1 has a working pipeline 10; the working instrument 3 includes an instrument body and a working hand piece 32, and the working hand piece 32 is installed on the instrument body; the channel sealing mecha...

Embodiment 2

[0073] Reference manual attached Figure 5 The second preferred embodiment of the channel sealing mechanism of the omnipotent hysteroscope provided by the present invention is described. The difference between the channel sealing mechanism of the omnipotent hysteroscope of the second preferred embodiment and the above-mentioned preferred embodiment is that , in the second preferred embodiment, further comprising a sleeve assembly installed on the working instrument 3, the sleeve assembly can prevent the working instrument 3 from The head end of 3 is in contact with the channel sealing mechanism 2, so that the head end of the relatively delicate working instrument 3 can be protected.

[0074] Reference manual attached Figure 5, specifically, the omnipotent hysteroscope further includes a sleeve assembly 4, and the sleeve assembly 4 is adapted to be installed on the instrument body 31 of the working instrument 3 for 31 provides protection for the head end of the instrument bo...

Embodiment 3

[0090] According to another aspect of the present invention, the present invention further provides a channel sealing method for the omnipotent hysteroscope, comprising:

[0091] During the process of inserting the working instrument 3 into the working pipeline 10, the elastic member 42 is pushed through the first locking part 51 of the working instrument 3 to drive the sleeve 41 located outside the working instrument 3 to move through together. channel sealing mechanism 2, and when the head end of the sleeve 41 passes through the channel sealing mechanism 2, the head end of the working instrument 3 is located in the sleeve 41; wherein the channel sealing mechanism 2 Located in the working pipeline 10;

[0092] When the head end of the sleeve 41 passes through the opening 20 of the sealing member 42 and moves a predetermined distance, it contacts the second locking part 52 installed in the working pipeline 10, allowing the working The instrument 3 continues to move forward re...

Abstract

The invention discloses a channel sealing valve, a channel sealing mechanism and an all-round hysteroscope, and the channel sealing valve comprises a first sealing part which is provided with a first opening; a second sealing piece is provided, the first sealing piece and the second sealing piece are arranged in a laminated mode, the position, corresponding to the first opening, of the second sealing piece protrudes in the direction away from the first sealing piece to form a protruding part, and a buffer cavity is formed between the protruding part of the second sealing piece and the first sealing piece; and the second protruding part is provided with a second opening. According to the channel sealing mechanism of the all-round hysteroscope, flowing-out of liquid in the working pipeline can be well reduced when the working instrument penetrates through the channel sealing mechanism, the working instrument is replaced and the working instrument is in a missing state, and the pressure of the liquid in the working pipeline in the use process of the hysteroscope is kept.

Description

technical field [0001] The invention relates to the field of hysteroscopes, and further relates to a channel sealing valve, a channel sealing mechanism and an all-round hysteroscope. Background technique [0002] Hysteroscopy can directly perform surgical treatment through hysteroscopy for all uterine space-occupying lesions, endometrial biopsy, adhesion release, and septate uterus. At present, the surgical instruments used with hysteroscopy include electric cutter instruments, cold knife instruments, and planer knife systems. [0003] It should be pointed out that in the state of instrument insertion, instrument replacement and instrument loss in the existing all-round hysteroscope, the liquid in the working pipeline often leaks a lot, which affects the normal use of the all-round hysteroscope. The leak-proof structure of the universal hysteroscope currently on the market is usually unable to prevent the leakage of liquid during the process of entering and pulling out the ...
