Vaginal dilator convenient for clinical use in gynaecology and obstetrics

Abstract

The invention discloses a vaginal dilator convenient for clinical use in the gynaecology and obstetrics. The device comprises a first handle, a second handle connected with the first handle through arotating shaft, and an expansion hinge integrally connected to the top end of the first handle and the top end of the second handle, wherein a flow channel is formed in the expansion hinge; a mountinggroove is formed in the position, located on the outer side of the flow channel, in the expansion hinge; and a half valve ball is elastically and movably connected into the mounting groove. Accordingto the vaginal dilator, through the design of the flow channel, a protective liquid can be conveniently stored in the expansion hinge, so that when the vaginal dilator is used, the vaginal wall skincan be lubricated, and the skin can be protected; through the structural design of the half valve ball and the like, the protective liquid can automatically flow out through extrusion of the vaginal wall when the vaginal dilator is used; through the design of a push spring, when the vaginal dilator is not pushed in, leakage of the protective liquid in the flow channel is avoided; and through the design of a connecting rod, a connecting handle, a threaded ring block and a threaded ring cylinder, the situation that the second handle is too long to cause certain obstruction to subsequent operation is avoided.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a vaginal dilation device convenient for clinical use in obstetrics and gynecology.
