Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a water passing structure used for passing water in a hysteroscope. Background Art

[0002] Minimally invasive surgery is becoming more and more common in the field of surgery due to its shorter recovery time, shorter duration of surgery and low cost. Minimally invasive surgery is usually performed by inserting instruments through small entrances or artificially formed openings in the patient. Hysteroscopic surgery is one of them. Hysteroscopy is mainly used in gynecology, such as fine needle puncture of ovarian cysts, pelvic adhesion separation, fallopian tube obstruction, twisting, adhesion correction, ectopic pregnancy surgery, uterine myoma removal, gynecological tumor surgery, subtotal and total hysterectomy for benign diseases. Hysteroscopic water insufflation is operated by water flow guided by hysteroscopy. It is a technology that operates by water flow guided by hysteroscopy. In this technology, the doctor inserts the hysteroscope into the woman's vagina and injects water into the uterine cavity under visual guidance to clean foreign objects or lesions in the uterine cavity, or to assist in intrauterine surgery. This method has the advantages of being intuitive and precise, able to clearly observe the situation in the uterine cavity, and the operation is relatively safe. Therefore, the effect of hysteroscopic water insufflation has a crucial impact on the corresponding treatment effect.

[0003] The utility model document with Chinese patent publication number CN220045860U discloses a hysteroscope, in which the liquid inlet and liquid outlet of the existing hysteroscope are independently designed with left and right forks, and the liquid inlet and the liquid outlet share a channel; the pipeline of the external water inlet equipment is connected to the liquid inlet for passing water (the water passed is usually physiological saline) into the hysteroscope; the pipeline of the external pumping equipment (also, water suction equipment) is connected to the liquid outlet for sucking away the water passed in. The left and right bifurcated independent design makes the pipes of the water inlet device connected to the liquid inlet and the water suction device connected to the liquid outlet scattered and easy to be intertwined, which seriously affects the convenience and flexibility of operation of the handle end of the hysteroscope and reduces the efficiency and accuracy of hysteroscopic surgery; the liquid inlet and the liquid outlet share a channel, so that the foreign matter or diseased tissue sucked away will adhere to the channel, and then when water needs to be passed again, these foreign matter or diseased tissue attached to the channel will re-enter the uterine cavity, causing repeated contamination of the uterine cavity, and then the uterine cavity cannot be completely cleaned, and the treatment effect is poor.

[0004] Therefore, there is an urgent need for a hysteroscope water-passing structure with a special design and having mutually independent liquid inlet and outlet channels. Utility Model Content

[0005] The utility model aims to provide a water-passing structure for a hysteroscope which has a type design and is provided with a liquid inlet channel and a liquid outlet channel which are independent of each other.

[0006] To achieve the above-mentioned purpose, the utility model provides a water-passing structure for a hysteroscope, which is used for docking and communicating with the insertion end of the hysteroscope, and the insertion end has a liquid inlet channel and a liquid outlet channel that are independent of each other, and is characterized in that the water-passing structure for a hysteroscope comprises a shell, a connecting piece, a first monomer valve and a second monomer valve, the shell comprises an upper shell and a lower shell, the upper shell and the lower shell are docked and snap-fitted with each other, a mounting platform protrudes outward from the lower shell, and the mounting platform has a horizontal mounting surface; the first monomer valve and the second monomer valve are fixedly arranged on both sides of the connecting piece in a left-right symmetrical manner and side by side, the connecting piece is carried on the mounting surface and is detachably connected to the mounting platform; the first monomer valve comprises a first valve body switch and a first inlet end and a first outlet end that are connectable to each other, the first inlet end is used to connect to an external water inlet device The first monomer valve comprises a second valve body switch and a second inlet end and a second outlet end which are connectable to each other, the second inlet end is used to communicate with the external water suction equipment, the second outlet end is used to communicate with the liquid outlet channel, the second valve body switch is arranged between the second inlet end and the second outlet end, and the flow rate between the second inlet end and the second outlet end and the closure are adjusted by rotating the second valve body switch; the first inlet end is arranged flush with the second inlet end, and the first monomer valve, the second monomer valve and the connecting piece are connected to form an integrated structure.

[0007] Compared with the prior art, the first monomer valve of the utility model is respectively connected to the liquid inlet channel and the external water inlet device, so that the physiological saline of the external water inlet device can enter the body for cleaning through the first monomer valve and the liquid inlet channel, and realize a dedicated inlet channel for the entry of physiological saline. The second monomer valve of the utility model is respectively connected to the liquid outlet channel and the external water suction device, so that the wastewater containing foreign matter or lesion tissue (i.e., the cleaned physiological saline) is sucked away by the external water suction device through the liquid outlet channel and the first monomer valve, and realizes a dedicated outflow channel for sucking away the wastewater (i.e., the cleaned physiological saline). The inlet channel for the entry of physiological saline and the outflow channel for sucking away the wastewater are independent of each other, which effectively avoids repeated contamination of the uterine cavity, ensures the thoroughness of the uterine cavity cleaning, and improves the treatment effect.
