Abstract

The utility model discloses a poultry uterus stretching speculum which comprises an upper stretching sheet, a lower stretching sheet and a handle, wherein the outer surfaces of the upper stretching sheet and the lower stretching sheet are in arc shape, and the arc-shaped openings are opposite to each other. The handle comprises a front handle and a rear handle, and the rear end of the upper stretching sheet is fixedly connected with the top end of the rear handle of the handle. A positioning hole is arranged on the rear handle, and the rear end of the lower stretching sheet is movably hinged with the rear handle. The lower portion of the lower stretching sheet is connected with the front handle of the handle, and the front handle is movably hinged with one end of a positioning rack through a torsion spring. The other end of the positioning rack penetrates through the positioning hole and enables tooth edges of the positioning rack and the positioning hole to be in states that different tooth edges clamp the positioning hole or the different tooth edges are separated from the positioning hole. The poultry uterus stretching speculum is simple in structure, convenient to use, safe, reliable, and capable of effectively stretching vaginas of the poultry, snooping uteruses of the poultry, and facilitating diagnosis for uterus diseases of the poultry.

Description

A kind of poultry metreurysma mouse

Technical field

This utility model relates to a kind of poultry medical apparatus and instruments, relates in particular to a kind of poultry metreurysma mouse for expanding, spy upon the poultry uterus.

Background technology

After the tradition poultry is ill, generally adopt medicament and injection to give treatment to, and the veterinary judge the basis of the state of an illness also stop be visible, on the external feature such as news, can not efficient diagnosis for some inherent sufferers.Poultry uterus health have a strong impact on its breeding, must spy upon by instrument, so that in time diagnosis and treatment for this reason.

The existing human vaginal dilator that uses, effectively vaginal dilation is convenient to find and the diagnosis and treatment hysteropathy.But when poultry was used, its structure size, length, arc, operation difficulty all were difficult to adapt to poultry and use.

Summary of the invention

The diagnosis of poultry hysteropathy can't be suitable for the deficiency that poultry is used without effective tool, the human vaginal dilator that uses in the prior art in order to solve, the purpose of this utility model has provided a kind of simple in structure, easy to use, safe, reliable, can effectively expand the poultry vagina, spy upon the poultry uterus, be convenient to the poultry metreurysma mouse of diagnosis and treatment poultry hysteropathy.

This utility model adopts following technical scheme: a kind of poultry metreurysma mouse, comprise outer surface is curved and arc port is relative upper and lower expanding plate and one handle, and its technical characterstic is that described handle comprises front handle and rear handle; The rear end of described upper expanding plate is fixedly connected on the rear handle top of handle, and rear handle is provided with a locating hole; The rear end of described lower expanding plate is movably articulated on the rear handle, the front handle of lower expanding plate below connecting handle, be movably hinged location tooth bar one end through torsion spring on the front handle, the location tooth bar other end passes locating hole makes the tooth mouth on the tooth bar of location be different tooth mouth chucking locating holes or throw off the locating hole state from locating hole.

Further, described upper and lower expanding plate activity closure is enclosed construction or gap counter structure.

Further the movable closed cross section of described upper and lower expanding plate be by rear end forward end gradual change dwindle circular or oval.

Again further, the front end closure of described upper and lower expanding plate is sphere or round and smooth arc-shaped curved surface.

The beneficial effects of the utility model are:

1, the front end closure of upper and lower expanding plate is sphere or round and smooth arc-shaped curved surface, and when upper and lower expanding plate was closed into the poultry vagina, front end is sphere or round and smooth arc-shaped curved surface can put in well, was difficult for the scratch vaginal wall, caused secondary injury, uses safety;

2, the movable closed cross section of upper and lower expanding plate be by rear end forward end gradual change dwindle circular or oval, circular or oval hungry cross section is convenient to upper and lower expanding plate and is closed in the poultry body, the closed rear end cross section is greater than front end section simultaneously, spy upon sight line open, be convenient to spy upon the uterus, improve diagnosis accuracy;

3, after closed upper and lower expanding plate enters the poultry vagina, lower expanding plate is around with rear handle pin joint rotation upper and lower expanding plate being opened, tooth mouth on the tooth bar of location is corresponding with rear handle locating hole, under the active force of torsion spring, will locate the rear handle locating hole of rack tooth mouth chucking, realize that upper and lower expanding plate expansion is fixing, need not be manually hand-held for a long time, be convenient to diagnosis and treatment are implemented to spy upon, perform the operation in the uterus; After the diagnosis and treatment, promotion location tooth bar overcomes the torsion spring active force makes the tooth mouth break away from locating hole, and the collapsible closure of upper and lower expanding plate is by taking out in the poultry body.

Description of drawings

Accompanying drawing 1 is structural representation of the present utility model.

In the accompanying drawing: upper expanding plate 1, lower expanding plate 2, front handle 3, rear handle 4, locating hole 5, torsion spring 6, location tooth bar 7, tooth mouth 8.
