Uterine cavity expander

Abstract

The invention discloses a uterine cavity expander. The uterine cavity expander comprises a rod body, an expansion head is arranged at the front end of the rod body, and a control handle is arranged at the rear end of the rod body; the expansion head comprises a plurality of elastic push rods and expansion rod units, wherein the elastic push rods take the center of the rod body as a symmetry axis and are arranged in the rod body in an annular array, the expansion rod units are matched with the corresponding elastic push rods, and the two ends of the elastic push rods are directly or indirectly hinged to the side surface of the expansion head; the end parts of the elastic push rods penetrate out of the side surface of the expansion head at an arc angle, clamping holes are formed in the end parts to abut against the surfaces of the expansion rod units, and an LED lamp unit is further arranged on the side surface of the expansion head; and the control handle is internally provided with a pushing device which allows the elastic push rods to move towards the expansion head and penetrates out along the arc angle to bend the expansion rod units and then enable the expansion head to expand in a spherical surface mode. According to the uterine cavity expander, a uterine cavity is mechanically expanded, a light source irradiates from inside to outside, very remarkable illumination is provided for the interior of the uterine cavity in a laparoscopic surgery, in addition, the monitoring performance of the uterine cavity is improved after expansion, excision of a myometrium is completed under the condition that an endometrium is not damaged, and the uterine cavity expander is puncture-proof, light in weight and high in operability.

Description

technical field [0001] The invention relates to an expander, in particular to a uterine cavity expander, and belongs to the technical field of IPC classification A61B. Background technique [0002] The structure of the uterus is composed of the mucous membrane, myometrium, and endometrium. The myometrium is the muscular tissue that supports the uterus. Myometrial diseases, commonly seen in uterine fibroids, and other similar diseases are treated by surgical resection. . [0003] Myometrial resection is usually performed with the help of laparoscopy. In laparoscopy, the external light of the uterine cavity is very limited, and the uterus is in a contraction state. Increasing the external light source to monitor the uterine cavity is extremely poor, and often damages the endometrium. , so it is very difficult for myometrial resection. Contents of the invention [0004] The present invention aims to solve the technical problem that the light in the existing uterine cavity i...
