Description
Technical field
The present invention relates to a kind of medical apparatus, specifically a kind of self-locking gynecological examination device.
Background technology
Gynecological examination device is again interior specula, is the medical apparatus that department of obstetrics and gynecology are conventional, and in existing duck-beak type, specula mainly consists of upper and lower two semicircular expanded support arms, by pressing handle, expanded support arm is opened, and is convenient to observe inner pathological changes situation.This interior specula cannot lock the position of expanded support arm when in use, must use all the time hand on handle, cannot use other inspections or therapeutic device, inconvenient operation simultaneously.Chinese patent 2012204694925 discloses a kind of < < with the gynecological examination device > > of locking mechanism, its agent structure still consists of expanded support arm and handle, just on the jointed shaft between expanded support arm and handle, fastening bolt is set, after pressing handle and making expanded support arm opened with certain angle, tighting a bolt makes it can resilience, reaches the object of locking expanded support arm state.But find in actual use, during the expansion of handle type expanding mechanism, require great effort, the wall thickness of expanded support arm is less, easily deforms and even fractures; Expansion resistance is large, and resilience force is also large, and less bolt cannot reach the object of locking, and larger bolt takes up room greatly, easily hinders and observes.
Summary of the invention
The object of the present invention is to provide that a kind of simple in structure, expansionary force is large, expanded support arm reasonable stress, can lock the self-locking gynecological examination device of expanded support arm, prevent from causing the distortion of expanded support arm or fractureing because of discontinuity.
In order to reach above object, technical scheme that the present invention adopts is: this self-locking gynecological examination device comprises hinged upper expanded support arm and lower expanded support arm, the front end of described upper expanded support arm and lower expanded support arm is semicircle tubulose, between described upper expanded support arm and lower expanded support arm, be hinged with front support circle and rear support circle, described front support circle and rear support circle are torus, the upper/lower terminal of front support circle and rear support circle is connected on the inwall of upper expanded support arm and lower expanded support arm by axle bed respectively, wherein at least one axle bed, torsion spring is installed.
The rear end of described upper expanded support arm and lower expanded support arm is symmetrically arranged with cover plate, and described cover plate is bell mouth shape, and the upper end of described rear support circle is hinged on the cover plate of expanded support arm, and the lower end of rear support circle is hinged on the semi-circular tube part of lower expanded support arm; The semi-circular tube of described upper expanded support arm is partly provided with spacer pin.
The inwall of described lower expanded support arm is provided with the chute of axial distribution, and the lower end axle bed cooperation of described front support circle and rear support circle is arranged in described chute, and the lower end axle bed of described front support circle and rear support circle is connected in series on pull bar.
Beneficial effect of the present invention is: rational in infrastructure, expansionary force is large, expanded support arm is balanced, be not easy distortion or fracture, without external force operation can self-locked at expansion state, be convenient to that medical personnel check or operation.

Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the end face structure schematic diagram of Fig. 1 embodiment.
Fig. 3 is the A-A cutaway view of Fig. 1.

The specific embodiment
As shown in Figure 1, self-locking gynecological examination device of the present invention, comprise hinged upper expanded support arm 1 and lower expanded support arm 2, the front end of described upper expanded support arm 1 and lower expanded support arm 2 is semicircle tubulose, during use, upper expanded support arm 1 and lower expanded support arm 2 are inserted to intravaginal, and in separation, expanded support arm 1 and lower expanded support arm 2 can form observation passage, for gynecological, detect or treatment.
Between described upper expanded support arm 1 and lower expanded support arm 2, be hinged with front support circle 3 and rear support circle 4, described front support circle 3 and rear support circle 4 are torus, the upper/lower terminal of front support circle 3 and rear support circle 4 is connected on the inwall of upper expanded support arm 1 and lower expanded support arm 2 by axle bed respectively, wherein at least one axle bed, torsion spring 5 is installed.Upper expanded support arm 1 and lower expanded support arm 2 and be hinged on during front support circle 3 and rear support circle 4 is common forms three-dimensional parallelogram sturcutre, Stability Analysis of Structures also can, by the distance between expanded support arm 1 and lower expanded support arm 2 in the angle of inclination adjustment of change front support circle 3 and rear support circle 4, reach and form the object of observing passage.
As shown in Figure 1, the rear end of described upper expanded support arm 1 and lower expanded support arm 2 is symmetrically arranged with cover plate 6,7, and described cover plate 6,7 is bell mouth shape, a complete conical horn mouth of the common formation of symmetrically arranged upper and lower two cover plates.The object that cover plate 6,7 is set can provide reference for the degree of depth of upper expanded support arm 1 and 2 insertions of lower expanded support arm on the one hand, avoids all slipping in body and cannot take out, and also can prevent that on the other hand in operation or checking process, various body fluid outflows pollute.The upper end of described rear support circle 4 is hinged on the cover plate 6 of expanded support arm 1, and the lower end of rear support circle 4 is hinged on the semi-circular tube part of lower expanded support arm 2, can make like this diameter of rear support circle 4 be greater than front support circle 3, facilitates folding operation.The semi-circular tube of described upper expanded support arm 1 is partly provided with spacer pin 8, for limiting the limit angle of inclination of rear support circle 4 or front support circle 3.
Torsion spring 5 makes expanded support arm 1 and lower expanded support arm 2 keep largest interval distance.During use, in extruding, expanded support arm 1 and lower expanded support arm 2 are drawn close both to be flat, be convenient to insert vagina, after insertion puts in place, unclamp hands, the expansionary force of torsion spring 5 makes rear support circle 4 swing to the position vertical with expanded support arm axle line, and expanded support arm 1 hoisting depth in promotion forms and observes passage between upper expanded support arm 1 and lower expanded support arm 2.If the elasticity of torsion spring is enough large, can only on an axle bed, torsion spring be installed therein, can certainly on a plurality of axle beds, torsion spring be installed.
As an alternative embodiment of the invention, the inwall of described lower expanded support arm 2 is provided with the chute 9 of axial distribution, the lower end axle bed cooperation of described front support circle 3 and rear support circle 4 is arranged in described chute 9, and the lower end axle bed of described front support circle 3 and rear support circle 4 is connected in series on pull bar 10.Pull pull bar 10 can make axle bed move axially in chute 9, can reach equally and change the inclination angle of bracing ring, the object that passage is observed in formation.
