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 is formed primarily of the semicircular expanded support arm of upper and lower two panels, by pressing handle, expanded support arm is opened, is convenient to observe inner pathological changes situation.This interior specula cannot lock the position of expanded support arm when in use, must use hand all the time on handle, other cannot be used to check or therapeutic device, inconvenient operation simultaneously.Chinese patent 2012204694925 discloses one " gynecological examination device with locking mechanism ", its agent structure is still made up of expanded support arm and handle, jointed shaft just between expanded support arm and handle arranges fastening bolt, after pressing handle makes expanded support arm opened with certain angle, tight a bolt and make it can not resilience, reach the object of locking expanded support arm state.But find in actual use, comparatively require great effort during the expansion of handle type expanding mechanism, 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 observation.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, expansionary force is large, expanded support arm reasonable stress, the self-locking gynecological examination device of expanded support arm can be locked, prevent because discontinuity causes expanded support arm be out of shape or fracture.
In order to reach above object, the present invention adopt technical scheme to be: 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 half-round tubular, front support circle and rear support circle is hinged with between described upper expanded support arm and lower expanded support arm, described front support circle and rear support circle are torus, the upper/lower terminal of front support circle and rear support circle is connected to respectively by axle bed on the inwall of upper expanded support arm and lower expanded support arm, wherein at least one axle bed is provided with torsion spring.
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 thereof of described rear support circle is on the cover plate of upper 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 part of described upper expanded support arm is 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, and expanded support arm is balanced, is not easy distortion or fractures, without the need to external force operation namely can self-locked at expansion state, be convenient to medical personnel and check or operation.

Fig. 3 is the A-A sectional view of Fig. 1.
Fig. 4 is mounted in the structure enlarged diagram of the axle bed in chute.
Detailed description of the invention
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 half-round tubular, during use, upper expanded support arm 1 and lower expanded support arm 2 are inserted intravaginal, and in separation, expanded support arm 1 and lower expanded support arm 2 can form observation passage, detect or treatment for gynecological.
Front support circle 3 and rear support circle 4 is hinged with between described upper expanded support arm 1 and lower expanded support arm 2, 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 to respectively by axle bed on the inwall of upper expanded support arm 1 and lower expanded support arm 2, wherein at least one axle bed is provided with torsion spring 5.The parallelogram sturcutre of upper expanded support arm 1 and lower expanded support arm 2 and the front support circle 3 during being hinged on and the common formation solid of rear support circle 4, Stability Analysis of Structures the upper distance between expanded support arm 1 and lower expanded support arm 2 of angle of inclination adjustment by changing front support circle 3 and rear support circle 4, reach the object being formed and observe 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, and symmetrically arranged upper and lower two cover plates form a complete conical horn mouth jointly.The degree of depth that the object arranging cover plate 6,7 can be inserted for upper expanded support arm 1 and lower expanded support arm 2 on the one hand provides reference, avoids all slipping in body and cannot take out, and also can prevent various body fluid in operation or checking process from flowing out on the other hand and pollute.The upper end thereof of described rear support circle 4 is on the cover plate 6 of upper 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, the diameter of rear support circle 4 can be made like this to be greater than front support circle 3, facilitate switching action.The semi-circular tube part of described upper expanded support arm 1 is provided with spacer pin 8, for limiting the extreme tilt angles degree 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 make both draw close in 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 with expanded support arm axes normal, expanded support arm 1 hoisting depth in promotion, is formed and observe passage between upper expanded support arm 1 and lower expanded support arm 2.If the elasticity of torsion spring is enough large, only an axle bed can installs torsion spring wherein, on multiple axle bed, torsion spring can certainly 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 that axle bed can be made to move axially in chute 9, the inclination angle changing bracing ring, the object forming observation passage can be reached equally.
