Description
Technical field
The utility model relates to a kind of medical instrument, especially a kind of self-locking vaginal dilator.
Background technique
Vaginal dilator is a kind of gynaecology's used vaginal dilation when doing examination per vagina and operation, exposure uterus entrance
Medical assistance instrument.
Existing vaginal dilator is there are many kinds of class, wherein more the most commonly used is using moving screw structure, with nut and
The screw vaginal dilator of screw lock opening angle and the slide calliper rule formula vaginal dilator designed using arc latch.And other
The vaginal dilator of angle can be locked, and structure is complicated, higher cost.As patent No. CN201720224843.9 is " a kind of anti-detachment
Highly reliable vaginal dilator ".
Latch-type vaginal dilator latch is unidirectional tooth, before solution lock lifts, can only unidirectionally be opened, such as the patent No.
CN201610757302.0.Including upper expanding plate and lower expanding plate, upper expanding plate and lower expanding plate pin joint, upper expanding plate includes upper
The wing, the push rod with upper limb integrally connected, upper expanding plate are equipped with peep pole；Lower expanding plate includes bottom wing and bottom wing integrally connected
Lower handle and the locating rod that is fixed on lower handle；Latch I is equipped on the side of push rod, on locating rod side side by side
There are several latches II that can be interlocked with latch I.The present invention has used the latch I on push rod can only be along in locating rod
The unidirectional principle of confounding of multiple latches II, is arranged at side for latch I and multiple latches II.
The vaginal dilator of screw-rod structure, such as patent No. 201621202059.X.It includes handle, the front end of the handle
Duckbilled is hingedly installed, and the basal sliding of handle is equipped with regulation handle, and the front end of regulation handle is fixedly installed with down
Duckbilled is spirally connected on the handle and is equipped with the first adjustment pin of adjustment regulation handle, and adjustment pin is screw-rod structure, the upper duckbilled
End be fixedly installed with regulating arm, and regulating arm is spirally connected by the fastening of the side wall of the second adjustment pin and handle.Screw-rod structure
Vaginal dilator is to be provided with self-locking screw in the part of screw rod in the outer part, due to lacking lock screw on the inside of screw rod, is opened
When angle deficiency, preferable locking can not achieve.
If installing an inside screw again on the inside of screw rod, need to adjust screw twice when using, it is more inconvenient.
Summary of the invention
Technical problem to be solved by the utility model is: the vaginal dilator inner angle for solving existing screw-rod structure is not square
Just the problem of locking, while requiring easy to use.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of self-locking vaginal dilator, You Shangkuo
Piece and lower expanding plate composition are opened, wherein upper expanding plate includes upper expansion cavity and regulating arm, lower expanding plate includes lower expansion cavity, handle
Portion, and it is provided with adjusting screw rod, which is characterized in that the cooperation adjusting screw rod is spindle nut；It is set in the middle part of nut
It is equipped with annular groove, regulating arm is inserted into the groove, and the first tentacle portion and the second tentacle portion of the two sides of nut press from both sides regulating arm
It is held in wherein.
Hinge hole is provided on the upper expanding plate, the shaft of lower expanding plate is inserted into the hinge hole.
Screw rod axis hole is provided on the lower expanding plate, the adjusting screw rod can be rotated around screw rod axis hole.
The regulating arm is door shape, and two side arms are inserted into respectively in the annular groove of nut.
It is additionally provided with lighting tube in the upper expansion cavity and rinses tube fixing device, lighting tube and flushing pipe are separately positioned on solid
Determine on frame.
Slip-resistant texture is provided in the first tentacle portion and the second tentacle portion of the spindle nut.
Compared with the prior art, the utility model uses spindle nut, adjusts the first tentacle portion or the second tentacle portion,
It is able to rotate screw, regulating arm effectively twin fixed guide-vane and can keep the opening of vaginal dilator always clamped by spindle nut
Angle.

Specific embodiment
The utility model is a kind of self-locking vaginal dilator, it by upper expanding plate 1, lower expanding plate 2 and adjusting screw rod 6,
Spindle nut 7 is formed.Expanding plate includes upper expansion cavity and regulating arm on upper expanding plate, and wherein regulating arm is door shape knot
Structure, lower expanding plate include lower expansion cavity, handle portion.
Wherein hinge hole, upper expanding plate and lower expanding plate is provided on upper expanding plate to be rotatablely connected by hinge hole.
Screw rod axis hole 5 is provided on lower expanding plate, one end of adjusting screw rod 6 is mounted on screw rod axis hole, and the other end is backward
Side extends, and is provided with spindle nut 7 on adjusting screw rod.Annular groove is provided in the middle part of the spindle nut, regulating arm is inserted
Enter in the groove, regulating arm is held on wherein by the first tentacle portion and the second tentacle portion of the two sides of nut.
Slip-resistant texture is provided in first tentacle portion and the second tentacle portion.
Since regulating arm is clamped between the first tentacle portion of spindle nut 7 and the second tentacle portion, front and back cannot
It is mobile, it solves in the prior art, the problem not being locked on the inside of screw vaginal dilator.And the spindle nut sheet
It is integrated, so arbitrarily adjusting the first tentacle portion or the second tentacle portion, screw can all rotate, adjusting gets up respectively to set than bilateral
The screw vaginal dilator for setting a nut is convenient.
