Description
Technical field
The present invention relates to a kind of medical apparatus, specifically a kind of Medical gynecological detector with locking mechanism.
Background technology
Gynecological examination device is called interior specula, is the conventional medical apparatus of department of obstetrics and gynecology, in existing duck-beak type specula mainly by it is upper,
The semicircular expanded support arm of lower two panels is constituted, and is opened expanded support arm by pressing handle, is easy to observe internal pathological changes situation.In this
Specula cannot lock the position of expanded support arm when in use, it is necessary to all the time with hand pressure on handle, it is impossible to while using other
Check or therapeutic device, inconvenient operation.Chinese patent 2012204694925 discloses one kind《Woman with locking mechanism
Section's detector》, its agent structure is still made up of expanded support arm and handle, simply set on the jointed shaft between expanded support arm and handle
Put fastening bolt, when pressing handle make expanded support arm opened with certain angle after, tighten bolt make its will not resilience, reach locking expand
The purpose of brace state.But find in actual use, handle type expanding mechanism is harder when expanding, the wall thickness of expanded support arm compared with
It is little, it is susceptible to deformation or even fractures；Expansion resistance is big, and resilience force is also big, and less bolt is unable to reach the purpose of locking, compared with
Big bolt takes up room greatly, easily hinders observation.
The content of the invention
It is an object of the invention to provide a kind of simple structure, expansionary force be big, expanded support arm reasonable stress, can lock expanded support
The Medical gynecological detector with locking mechanism of arm, prevents because discontinuity causes the deformation of expanded support arm or fractures.
In order to reach object above, the present invention using technical scheme is：Should the Medical gynecological inspection with locking mechanism
Device include the upper expanded support arm being hinged and lower expanded support arm, the upper expanded support arm and lower expanded support arm front end be half-round tubular, it is described on
Front support circle and rear support circle is hinged between expanded support arm and lower expanded support arm, and the 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, its
In torsion spring is installed at least one axle bed；The rear end of the upper expanded support arm and lower expanded support arm is symmetrically arranged with cover plate, the cover
Plate is bell mouth shape；Rear support circle with diameter greater than front support circle；The upper end of the rear support circle is hinged on the cover of expanded support arm
On plate, the lower end of rear support circle is hinged on the semicircle tube portion of lower expanded support arm；The semicircle tube portion of the upper expanded support arm is provided with limit
Position pin；The inwall of the lower expanded support arm is provided with the lower end axle bed of the chute of axially distribution, the front support circle and rear support circle
Coordinate in the chute, the lower end axle bed of the front support circle and rear support circle is connected in series on pull bar.
The beneficial effects of the present invention is：Rational in infrastructure, expansionary force is big, and expanded support arm is balanced, it is not easy to deforms or fractures,
Without the need for external force operate i.e. can self-locked in expansion state, be easy to medical personnel check or perform the operation.
Description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the end face structure schematic diagram of Fig. 1 embodiments.
Fig. 3 is the A-A sectional views of Fig. 1.
Fig. 4 is mounted in the structure enlarged diagram of the axle bed in chute.
Specific embodiment
As shown in figure 1, the Medical gynecological detector with locking mechanism of the present invention, including the upper expanded support arm 1 being hinged
Front end with lower expanded support arm 2, the upper expanded support arm 1 and lower expanded support arm 2 is half-round tubular, during use, by upper expanded support arm 1 and lower expansion
Intravaginal is inserted in brace 2, and in separation, expanded support arm 1 and lower expanded support arm 2 can form observation passage, detect for gynecological or treat.
Front support circle 3 and rear support circle 4, the front support circle 3 is hinged between the upper expanded support arm 1 and lower expanded support arm 2
Upper expanded support arm is connected to by axle bed respectively with upper/lower terminal of the rear support circle 4 for torus, front support circle 3 and rear support circle 4
1 and lower expanded support arm 2 inwall on, torsion spring 5 is installed on wherein at least one axle bed.Upper expanded support arm 1 and lower expanded support arm 2 and hinge
Front support circle 3 and rear support circle 4 during being connected on collectively forms the parallelogram sturcutre of solid, and Stability Analysis of Structures simultaneously can be by changing
Become the distance between the upper expanded support arm 1 of the angle of inclination adjustment of front support circle 3 and rear support circle 4 and lower expanded support arm 2, reach to form sight
Examine the purpose of passage.
As shown in figure 1, the rear end of the upper expanded support arm 1 and lower expanded support arm 2 is symmetrically arranged with cover plate 6,7, the cover plate 6,7
For bell mouth shape, symmetrically arranged upper and lower two cover plates collectively form a complete conical horn mouth.Cover plate 6,7 is set
The depth that on the one hand purpose can be inserted for upper expanded support arm 1 and lower expanded support arm 2 provides reference, it is to avoid all slips into and cannot take in vivo
Go out, on the other hand flow out prevented also from various body fluid in operation or checking process and pollute.The upper end hinge of the rear support circle 4
It is connected on the cover plate 6 of expanded support arm 1, the lower end of rear support circle 4 is hinged on the semicircle tube portion of lower expanded support arm 2, can so make
Rear support circle 4 with diameter greater than front support circle 3, facilitate switching action.The semicircle tube portion of the 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 is with
Expanded support arm 2 makes both draw close in flat, facilitates insertion into vagina, after insertion in place, unclamps handss, after the expansionary force of torsion spring 5 makes
Bracing ring 4 swings to the position vertical with expanded support arm axle line, 1 hoisting depth of expanded support arm in promotion, in upper expanded support arm 1 and lower expanded support
Observation passage is formed between arm 2.If torsion spring is elastic sufficiently large, torsion spring can be installed on an axle bed wherein only, certainly
Torsion spring can also be installed on multiple axle beds.
Used as an alternative embodiment of the invention, the inwall of the lower expanded support arm 2 is provided with the chute 9 of axially distribution, institute
The lower end axle bed for stating front support circle 3 and rear support circle 4 coordinates in the chute 9, the front support circle 3 and rear support circle
4 lower end axle bed is connected in series on pull bar 10.Pull pull bar 10 that axle bed can be made to move axially in chute 9, equally can be with
Reach the inclination angle for changing bracing ring, the purpose for forming observation passage.
