Abstract

The invention discloses a suction head specially used for induced abortion operation. The suction head is a communicated pipeline and comprises a suction head top end, a catheter and a suction head tail part, wherein the suction head top end is inwards sunken, and a suction hole is formed in a sunken part; the suction head tail part is connected with a connection head; the other end of the connection head is connected with a negative pressure aspirator; an air inlet pipe is arranged on the catheter; an air inlet valve is arranged on the air inlet pipe. According to the novel suction head provided by the invention, the switchable air inlet valve and an expanded nut with a filter net are arranged at the tail end. The suction head is simple in structure, convenient to use, economical and practical; when the suction head gets into and gets out of a uterine cavity, the operation that a rubber pipe is repeatedly kneaded by an operator with a hand is avoided; tissues aspirated from the uterine cavity are directly taken out from the filter net, and the time of taking out a sample from a negative pressure aspirator bottle is saved; the whole operation is simple and quick.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a medical surgical suction head. Background technique [0002] Known, when obstetrics and gynecology carries out artificial abortion operation to premature pregnant woman, connect rubber tube with suction head, the other end of its rubber tube connects negative pressure aspirator. When the sensory cavity is gradually shrinking and the uterine wall is close to the suction head, it means that the pregnancy tissue has been sucked. At this time, you need to squeeze the rubber tube with your hands before removing the suction head. Be careful not to bring in and out the suction head with negative pressure each time. cervical canal. Otherwise, it will cause damage to the cervical canal, causing postoperative amenorrhea and other postoperative complications. The aspirated tissue needs to be poured out from the aspirator bottle and filtered with a filter before the tissue can be inspect...
