Technical field
This utility model relates to gynecilogical operation medical instruments, particularly a kind of gynecologic operation cervix dilator.
Background technology
At present, clinically when carrying out gynecologic operation cervix expansion to patient, it is used mostly interior specula cervix dilating, and interior specula needs to press all the time handle, and degrees of expansion and dynamics be difficult to hold, operate cumbersome, waste time and energy, add great work difficulty to medical worker.
Utility model content
For above-mentioned situation, for overcoming the defect of prior art, this utility model provides a kind of gynecologic operation cervix dilator, and effectively solving existing equipment needs to press all the time handle, and the problem that degrees of expansion and dynamics are difficult to hold carrying out cervical dilatation when.
This utility model includes support shaft, the anterior slip cap of described support shaft is equipped with mounting seat, it is evenly distributed in described mounting seat and organizes connection rod set more, the connecting rod that described connection rod set is fixed in mounting seat by a rotation is constituted, the expansion cylinder of setting with interval it is cased with in described support shaft, described expansion cylinder is divided into the arcuate member of the number equal with connection rod set, the link rotatable of each connection rod set is contained on arcuate member corresponding thereto, in the support shaft of described mounting seat front end, suit is fixed with limit base, it is fixed with expansion link between described arcuate member and limit base, described support shaft rear portion is provided with external screw thread, described mounting seat rear end is fixed with slip cap connecting cylinder in support shaft, thrust cylinder has been screwed on the external screw thread at described connecting cylinder rear portion, described support shaft rear end is coaxially connected with holding rod.
This utility model simple in construction, easy and simple to handle, it is achieved that to Cervical electrodeless expansion, and it is strong, with auto-lock function to expand degree controllability.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
nullBe given by Fig. 1 to Fig. 4，The technical solution of the utility model is，Including support shaft 1，The anterior slip cap of described support shaft 1 is equipped with mounting seat 2，Many group connection rod set 3 it are evenly distributed in described mounting seat 2，The connecting rod 301 that described connection rod set 3 is fixed in mounting seat 2 by a rotation is constituted，The expansion cylinder 4 of setting with interval it is cased with in described support shaft 1，Described expansion cylinder 4 is divided into the arcuate member 401 of the number equal with connection rod set 3，The connecting rod 301 of each connection rod set 3 rotates on the arcuate member 401 being contained in corresponding thereto，In the support shaft 1 of described mounting seat 2 front end, suit is fixed with limit base 5，It is fixed with expansion link 6 between described arcuate member 401 and limit base 5，Described support shaft 1 rear portion is provided with external screw thread 7，Described mounting seat 2 rear end is fixed with slip cap connecting cylinder 8 in support shaft 1，Thrust cylinder 9 has been screwed on the external screw thread 7 at described connecting cylinder 8 rear portion，Described support shaft 1 rear end is coaxially connected with holding rod 10.
Described connection rod set 3 is parallel to each other by two and rotates the connecting rod 301 being fixed in mounting seat 2 and constitutes.Above-mentioned connection rod set 3 is changed into two so that its stability is higher by one.
Described support shaft 1 front end is fixed with head 12 through coaxially connected connecting rod 11, and curved and its end face the external diameter in the cross section of described head 12 is identical with expansion cylinder 4 external diameter.When expansion cylinder 4 now is combined for arcuate member 401.
Described connection rod set 3 has four groups.
When mounting seat 2 touches limit base 5, if during a connecting rod 301, now connecting rod 301 is the most vertical with support shaft 1, if during two connecting rods 301, two connecting rod 301 constitutes rectangle, arcuate member 401 now is expanded to maximum, if needing the supporter by arcuate member 401 is constituted to reduce, have only to pull back mounting seat 2, when pulling back mounting seat 2, mounting seat 2 drivening rod 301 rotates relative to mounting seat 2 and arcuate member 401, now arcuate member 401 is spacing in the range of moving radially by expansion link 6, therefore when mounting seat 2 moves axially, arcuate member 401 can be driven to move radially, to reach the purpose expanded or shunk, when not being spaced between multiple arcuate members 401 and synthesize expansion cylinder 4, during for its diameter minimum.When this utility model uses, this utility model transvaginal is driven to be passed into cervix uteri by the head 12 of front end, then with hand-held holding rod 10, rotate thrust cylinder 9, thrust cylinder 9 rotates moved axially forward, connecting cylinder 8 is driven to move forward, connecting cylinder 8 promotes mounting seat 2 to move forward, mounting seat 2 drives arcuate member 401 to expand through connection rod set 3, and then vagina is served dilating effect, during expansion, electrodeless expansion by the way of screw thread rotation, and according to the auto-lock function of screw thread, the thrust cylinder 9 that stops the rotation the most afterwards can be expanded to, arcuate member 401 is navigated to its position arrived, it is controlled the expansion of arcuate member 401 by screw thread rotation or reduces, make its degree expanded controlled.When in use, it is also possible to use the length of tape measure thrust cylinder 9 feeding, and then learn the degree that arcuate member 401 is expanded.
This utility model simple in construction, easy and simple to handle, it is achieved that to Cervical electrodeless expansion, and it is strong, with auto-lock function to expand degree controllability.
