DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a disposable uterine cavity tissue suction tube, comprising a suction tube body 1, a suction port 2 is opened in the lower half area of ​​the left side of the suction tube body 1, and a handle mechanism 3 is arranged at the top of the suction tube body 1;

[0023] The handle mechanism 3 includes a semicircular sleeve 301 and a handle 302. The semicircular sleeve 301 is fixedly mounted on the top of the suction tube body 1. The opening of the semicircular sleeve 301 faces the right side of the suction tube body 1. The handle 302 is slidably arranged on the inner wall of the semicircular sleeve 301. An elastic silicone plate 303 is fixedly mounted on the right outer wall of the semicircular sleeve 301. A slot 304 is provided on the right outer wall of the elastic silicone plate 303. A post 305 is fixedly mounted on the outer wall of the handle 302. The post 305 is clamped in the slot 304. The elastic silicone plate 303 is integrally formed with the semicircular sleeve 301. There are a plurality of slots 304, which are evenly spaced on the elastic silicone plate 303. A slot 304 is provided on the elastic silicone plate 303 integrally formed with the semicircular sleeve 301 for installing the post 305. Then, the handle 302 is connected to the semicircular sleeve 301. By clamping the post 305 in The spacing between the handle 302 and the suction tube body 1 is adjusted in the card slot 304 at different positions, thereby realizing the adjustment of the length of the gripping section. When the use is over, the card column 305 can be pulled out from the card slot 304 by force, thereby realizing the separation of the handle 302 and the semicircular sleeve 301. Moreover, because the opening direction of the semicircular sleeve 301 is opposite to the direction of the suction port 2, the suction port 2 is the main contact position between the suction tube body 1 and the human body during use. Therefore, after the force exerted by the human body on the suction tube body 1 is transmitted to the semicircular sleeve 301, it will be transmitted to the handle 302 from left to right, thereby preventing the semicircular sleeve 301 from rotating relative to the handle 302, thereby ensuring the use effect. The outer wall of the card column 305 is fixedly installed with an anti-skid sleeve 4, which is clamped in the card slot 304, thereby increasing the friction between the card column 305 and the inner wall of the card slot 304, thereby further preventing the card column 305 from detaching from the card slot 304.

[0024] A mounting sleeve 5 is fixedly mounted on the outer wall of the top of the handle 302, and a movable sleeve 7 is slidably mounted on the outer wall of the mounting sleeve 5. A convex strip 6 is fixedly mounted on the outer wall of the movable sleeve 7, and a sliding groove 8 is opened on the inner wall of the movable sleeve 7. The convex strip 6 is slidably arranged in the sliding groove 8. A movable sleeve 7 that can slide relative to the mounting sleeve 5 is provided, and is used to cover the semicircular sleeve 301 after the handle 302 is installed, so as to prevent the semicircular sleeve 301 from being exposed to the outside and strengthen the connection strength between the semicircular sleeve 301 and the handle 302. The movable sleeve 7 can be regarded as an extension of the handle 302 together with the mounting sleeve 5, and then when the handle 302 needs to be taken out by holding the mounting sleeve 5 or the movable sleeve 7 during use, it is only necessary to pull the movable sleeve 7 to separate the movable sleeve 7 from the semicircular sleeve 301, and then move the clamping column 305 horizontally out of the clamping groove 304. The top end of the movable sleeve 7 is inserted into the limiting ring 9 to limit the position of the movable sleeve 7 so as to prevent the movable sleeve 7 from sliding relative to the mounting sleeve 5 when the handle 302 is installed in the semicircular sleeve 301.

[0025] Working principle: When in use, pull up the movable sleeve 7 so that the movable sleeve 7 moves to the top, and then push the handle 302 horizontally into the semicircular sleeve 301. During the pushing process, the clamping column 305 will squeeze the elastic silicone plate 303, causing the elastic silicone plate 303 to deform until the clamping column 305 is pressed into the corresponding clamping groove 304, completing the installation of the handle 302. Pull down the movable sleeve 7 so that the bottom end of the movable sleeve 7 is clamped into the limiting ring 9 to complete the fixation of the movable sleeve 7. The user can hold the installation sleeve 5 or The movable sleeve 7 uses the entire disposable uterine cavity tissue suction tube. After use, pull up the movable sleeve 7 to separate the movable sleeve 7 from the semicircular sleeve 301, and then pull the semicircular sleeve 301 horizontally to drive the clamping column 305 to move until the clamping column 305 is disengaged from the clamping groove 304. The semicircular sleeve 301, the elastic silicone plate 303, and the limiting ring 9 are discarded together with the suction tube body 1 as disposable structures, and the handle 302, the installation sleeve 5, the movable sleeve 7 and other structures can be disinfected, recycled and reused, reducing the waste of resources.

[0026] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
