Abstract
A kind of umbrella shape vaginal dilator, comprises the support be made up of multiple spring leaf, is coated with elastica outside support, blade rear end is interconnected, and surrounds a circumference, and side, front end is provided with draw-in groove, opposite side is provided with buckle, can engage and can be unclamped by elastic deformation under external force; During blade engaging, point diameter is less than rear end diameter, conveniently inserts, inserts rear pressing blade; there is elastic deformation under external force; buckle and the draw-in groove of clamping are opened, and blade is not fastening state, and point diameter is greater than rear end diameter; blade is relative to the radial opening in its rear end; 360 ° of tights, as umbrella shape, elastica is covered between blade; prop up and protect vaginal wall, adding field of view and operative space.
Description
Technical field
This utility model relates to gynecological's medical apparatus and instruments, specifically, relates to a kind of umbrella shape vaginal dilator.
Background technology
Vaginal dilator be gynecologial examination and the operation of diagnostic curettage class time conventional a kind of medical apparatus and instruments, gynecologist carrying out cervical biopsy, cervix uteri cone is when the operation on cervix treatment such as to cut, with vaginal dilator, vaginal orifice need be expanded, play the effect exposing cervix uteri, to check intravaginal or to perform the operation.At present, vaginal dilator conventional in gynecologial examination is made up of upper and lower mandible, handle and bindiny mechanism usually, in use, can will stretch into intravaginal upper and lower mandible by bindiny mechanism to open, opening is formed between upper and lower mandible, and undertaken checking or performing the operation by open view vaginal walls, but some patients is because of reasons such as obesity, slack vagina, vagina vegetations, cause being extruded with vaginal wall during common duckbill vaginal speculum being piled up in intravaginal, block patient's sight line, be unfavorable for operation, and easy damaged vagina tissue when coagulation or cutting.
Utility model content
The purpose of this utility model be to provide a kind of structure simple, easy to use, increase field of view and operative space, patient is without the umbrella shape vaginal dilator of sense of discomfort.
The technical scheme that this utility model is complete is:
A kind of umbrella shape vaginal dilator, it is characterized in that, comprise support, described support comprises multiple blade 1, be coated with elastica 2 outside described blade, described blade is made up of elastomeric material, and rear end 3 is interconnected, surround a circumference, the diameter of this circumference is the first diameter D1
Described vane nose 4 is round and smooth duckbill configuration, and side is provided with draw-in groove, and opposite side is provided with buckle, and described buckle and draw-in groove can engage, and can be unclamped by elastic deformation under external force;
After whole blade engaging, its front end surrounds another circumference, and the diameter of this another circumference is Second bobbin diameter D2, and described Second bobbin diameter is less than the first diameter D1, namely shrinks relative to its rear end,
Whole blade radially flicks when not engaging, and props up elastica, and its front end forms the 3rd circumference, and the diameter of the 3rd circumference is the 3rd diameter D3, and the 3rd described diameter D3 is greater than the first diameter D1, namely relative to the radial opening in its rear end.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that umbrella shape vaginal dilator disclosed in the utility model is in fastening state;
Fig. 2 is the schematic diagram that umbrella shape vaginal dilator disclosed in the utility model is in not fastening state;
Fig. 3 is the buckle notch schematic diagram of umbrella shape vaginal dilator vane nose disclosed in the utility model;
In figure: 1 is blade, 2 is elastica, and 3 is blade rear end, and 4 is vane nose, and 5 is buckle, and 6 is draw-in groove.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described,
A kind of umbrella shape vaginal dilator, it is characterized in that, comprise support, described support comprises multiple blade 1, be coated with elastica 2 outside described blade, described blade is made up of elastomeric material, and rear end 3 is interconnected, surround a circumference, the diameter of this circumference is the first diameter D1
Described vane nose 4 is round and smooth duckbill configuration, and side is provided with draw-in groove, and opposite side is provided with buckle, and described buckle and draw-in groove can engage,
After whole blade engaging, its front end surrounds another circumference, and the diameter of this another circumference is Second bobbin diameter D2, and described Second bobbin diameter D2 is less than the first diameter D1, namely shrinks relative to its rear end,
Whole blade radially flicks when not engaging, and props up elastica, and its front end forms the 3rd circumference, and the diameter of the 3rd circumference is the 3rd diameter D3, and the 3rd described diameter D3 is greater than the first diameter D1, namely relative to the radial opening in its rear end.
During use, first buckle 5 and draw-in groove 6 is utilized to engage in whole blade 1, vaginal dilator is now in contraction state, elastica 2 (being represented by dotted lines in figure) is affixed on blade surface, now point diameter D2 is less than rear end diameter D1, conveniently be placed in body, after inserting, press any a slice blade 1, because blade is that elastomeric material is made, there is elastic deformation under external force, buckle and the draw-in groove of clamping are opened, now the fastening state of blade is destroyed, blade outwards flicks in resilient force, prop up elastica, point diameter D3 after strutting is greater than D1, blade is relative to the radial opening in its rear end, 360 ° of tights, as umbrella shape, elastica is covered between blade, prop up and protect vaginal wall, add field of view and operative space.
