DETAILED DESCRIPTION

[0026] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

Embodiment 1

[0027] Referring to FIG. 1, FIG. 2 and FIG. 3, the hysteroscopic instrument operation propeller according to the present application includes a propelling body 2 and a sheath 3, and one side surface of the propelling body 2 is a concave large semi-cylindrical surface, forming the engagement groove of the propelling body 2, the propelling body 2 can be reliably attached to the hysteroscope body 1 through the engagement groove, and the other side surface of the propelling body 2 (the back of the engagement groove) is provided with a convex strip 2-1. The sheath 3 has a sleeve body designed with a bullet-shaped shape, and the sleeve body is provided therein with a space configured for accommodating the sharp front end of the scissors, and easily damaged front ends of electric cutters, electric cutting rings, electro-acupunctures, electrocoagulation rods, etc., and further provided with a slide rail fixed on the inner wall of the sleeve body (the convex groove type can be used). The convex strip 2-1 is embedded in the slide rail and can slide relative to the slide rail (along the axis of the hysteroscope body). The sliding of the sleeve body is driven by an operating rod 3-1, one end of the operating rod 3-1 is fixed on the outer side wall of the slide rail (does not affect the sliding of the slide rail and the convex strip), and the other end faces the rear end of the hysteroscope body 1-1 and extends out the sleeve body (the length is suitable for easy holding operation); the surface portion of the propelling body 2 between the opening of the engagement groove and the corresponding side of the convex strip 2-1 is an outwardly convex arc-shaped, which can reduce the interference with the surrounding tissue. The surrounding tissue can also be separated from the convex strips 2-1 to a certain extent, so as to avoid affecting the sliding process of the sleeve body to the greatest extent. The length of the propelling body 2 is about 115 mm (the length of the hysteroscope body is about 200 mm), and the length of the sleeve body is about 15 mm, both of them can be made of stainless steel. After the propelling body 2 is engaged on the hysteroscope body 1, the distance between the front end of the propelling body 2 and the front end of the hysteroscope body can be adjusted (for example, after the propelling body 2 is observed in the hysteroscope monitoring area). The front end of the propelling body 2 can be processed into an arc-shaped to facilitate the movement of the propelling body 2 (for example, to reduce hooking and dragging with surrounding tissues), and which can also reduce the shielding of the hysteroscope monitoring area (especially when the front end of the propelling body 2 approaches the front end 1-2 of the hysteroscope body or overlaps with the front end 1-2 of the hysteroscope body), the sheath 3 sliding on the convex strip 2-1 can be positioned accurately, so as to fully play a protective role in the movement of the instrument.

[0028] During hysteroscopic surgery, the propelling body 2 is firstly installed (pressed or inserted) on the rear end 1-1 of the hysteroscope body, then the hysteroscope body 1 is sent into the uterus. During the hysteroscopy process, when polyps, intrauterine adhesions, submucosal fibroids, etc. are found in the uterine cavity, the instrument can be sent for treatment. At this time, according to the width of the internal orifice of the cervical canal, the front end 1-2 of the hysteroscope body is kept at the uterine cavity or the internal orifice of the cervical canal, and the front end of the propelling body 2 is pushed into the front end 1-2 of the hysteroscope body and stop until the front end of the propelling body 2 can be seen on the display of the hysteroscope, and the propelling body 2 can be pushed or pulled slightly to adjust the position of the front end of the propelling body 2 (to ensure that the field of view of the hysteroscope monitoring area on the display is always good before the sheath 3 enters and after the instrument enters), the sleeve body of the sheath 3 is connected to the convex strip 2-1 (through the slide rail), and then the front end of the scissors, electro-acupunctures, electro-cutting rings and other instruments of the laparoscope are put into the sleeve body (whichever instrument needs to be used, put it into the sleeve body), the sleeve body is pushed to the front end 1-2 of the hysteroscope body using the operating lever 3-1(push the instrument together), until the tail of the sleeve body is seen on the display of the hysteroscope. The scissors or electro-acupunctures or electric cutting rings and other instruments are removed from the sleeve body under the direct view of the hysteroscope, and when the normal treatment operations can be performed. When it is necessary to replace the instruments for the treatment operation, withdraw the instruments currently used for the operation (if the instruments need to be replaced during the treatment, such as scissors, they can be taken out directly after they are folded, the instruments such as electro-acupuncture, electric cutting rings, etc. that are not easy to take out, which can be put into the sleeve body and take it out together with the sheath), and then repeat the above method of sending the instrument, and then the new treatment operation can be continued.

[0029] Since polyps, intrauterine adhesions, and submucosal fibroids are found in the uterine cavity during the hysteroscopy, it was necessary to enter the treatment instruments. By using the above propeller, when the instruments pass through the blind areas of the vagina and cervical canal, which can be smoothly sent into (and withdrawn from) the uterus along the hysteroscope body 1 that has already entered, therefore, the interval time between treatment operations can be shortened, and since the device integrating the hysteroscope body and the instrument is no longer required, the cervix is required to be about 6 mm, so that some conventional treatments basically do not need to dilate of the cervix, which can reduce the intraoperative pain of the patient and avoid hospitalization. Furthermore, the operation of the instrument is less restricted, and it can be operated continuously and flexibly under the hysteroscopic field of view provided by the display. In addition, it can also meet the objective requirements for the durability and easy availability of the treatment instrument, and selecting to use the treatment instrument with the structure being simpler and the size being larger (which makes the instrument easier to handle and less prone to damage).

Embodiment 2

[0030] Referring to FIG. 4, the difference from the embodiment 1 is that the operating rod 3-1 is increased from one to two, and connected to a U-shaped structure, and the fixed position of the operating rods 3-1 at the slide rail are adjusted from the lower side to the upper side, in addition, a handle 2-2 is added to the propelling body 2, so that the operation of the propeller is more convenient.

[0031] In a word, the hysteroscopic instrument operation propeller of the present application is beneficial for doctors to quickly, accurately and non-invasively send the treatment instrument into the uterus, and the treatment process can be completed in the outpatient operating room, which not only reduces the treatment cost, but also achieves a good treatment effect.
