Problems solved by technology

Since the uterine cavity is deep at this time, when a conventional artificial flow suction tube is used for suction, in order to clear the depth of the uterine cavity, the part of the artificial flow suction tube extending into the uterus is longer, and the remaining hand-held part is too short to apply force, and it is difficult for the instrument to reach the surgical site , may cause the patient to undergo a second curettage, increasing the chances of bleeding and infection

Abstract

The invention discloses a cannula device for fixing a curettage instrument. The cannula device comprises a cannula body and a connecting device, wherein the connecting device is detachably connected with cervical clamps, the cannula body is hollow and comprises a front end and a rear end, the front end of the cannula body is connected with the curettage instrument capable of entering the body for operation, and the rear end of the cannula body is away from the operation end. The cannula device is used in cooperation with the conventional curettage instrument, an induced abortion suction tube can be taken and placed conveniently on the premise that infection is avoided, the usable length of the induced abortion suction tube can be increased, and then operation difficulty is lowered and the operation is facilitate.

Description

technical field [0001] The invention relates to a medical instrument used in curettage surgery, in particular to a sleeve device for fixing the curettage surgical instrument. Background technique [0002] Curettage is the operation of scraping and removing the endometrium or the contents of the uterine cavity. Surgical methods mainly include negative pressure aspiration and curettage. Uterine curettage is an invasive gynecological operation in which medical instruments enter the body. During the operation, curettes and suction tubes need to be used alternately to operate in the uterine cavity. Especially, the middle and upper parts of the suction tube need to go in and out of the uterus repeatedly. Strictly control the middle and upper part of the suction tube of people flow so that it cannot touch any foreign matter, otherwise it will easily cause pollution. However, because the existing abortion suction tube cannot be fixed, when the abortion suction tube is idle during ...
