Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of intelligence duplicate rows formula gynaecology extension fixture.
Background technique
In gynecologial examination activity, uterus dilatation device is the one kind being commonly used.The uterus dilatation device of the prior art is using hinge
A pair of of expansion board progress of state is connect, " eight " font that front end is close and rear end is separate is presented to expansion plate using previous, is adjusted
A pair, which expands plate rear end, makes it move closer to that a pair of expansion front edge of board can be pried open, and is realized and is expanded by a pair of expansion for expanding front edge of board
Palace effect.
However it is limited to the simple articulated structure of the prior art, and when needing to carry out large range of expansion to vagina, one
To front edge of board is expanded, gradually bifurcated is shaped to " eight " font that front end is separate and rear end is close, cannot keep parallel orientation, and
A pair expands front edge of board and causes discomfort to patient's body Tissue approximation.
Therefore need to design it is a not only can carry out expansion palace by hingedly acting on, but also can keep a pair of of expansion board in parallel into
And avoid the extension fixture for making patient's discomfort.
Summary of the invention
In order to solve the technical problems in background technology, the present invention provides a kind of intelligent duplicate rows formula gynaecology expansion
