Description
Technical field
This utility model belongs to medical surgical instrument, is specifically related to a kind of vaginal dilator.
Background technology
Vaginal dilator is to be used for the department of obstetrics and gynecology vaginal dilation, carries out the operating theater instruments of vagina, cervix uteri and uterine cavity inspection and treatment.The vaginal dilator of present clinical use has two kinds: a kind ofly make with the stainless steel metal material, structure is divided upper and lower leaf, link to each other to constitute a duckbill barrel-like structure with axle between two leaves, last leaf one side has handle, inferior lobe side helical form thick stick axle passes in the middle of handle, be used for regulating the closed degree of dilator, metallic article can clean repeatedly, uses repeatedly; Another kind is the disposable vagina expander that plastics are made, and upper and lower two leaf front-end architectures are Duckbill types, still connect between two leaves with axle, back-end closure ringwise, there are two tongue structures the lower end, the centre has a tooth post to run through, and plays adjusting dilator size and acts on.The drawback of metal dilator is that the helical form fixing operation is loaded down with trivial details, and two leaves connect and can not separate with axle, and when particularly cooperating peritoneoscope to lift the palace operation, time length is brought misery to the patient, very inconvenience of band device operation.The drawback of plastics dilator be back-end closure ringwise, gathering hole is narrow, tail end is outstanding and the tooth post is arranged, and is awkward.
Summary of the invention
Goal of the invention of the present utility model provides big, detachable, the easy to operate vaginal dilator in a kind of visual field.
The technical solution of the utility model is: comprise leaf, inferior lobe, two leaves are fastened as a duckbill barrel-like structure mutually; Last leaf one side is provided with handle, and there is bayonet socket last leaf both sides, and the inferior lobe both sides have and the corresponding axle of last leaf bayonet socket, and inferior lobe one side is provided with the zigzag adjusting rod, and handle is provided with and is used for the slot that the zigzag adjusting rod penetrates.
Compared with prior art, advantage of the present utility model is: simple in structure, the visual field is big, detachable, operate more convenient, patient comfort, no pain, cost is low.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an impeller structure sketch map on this utility model.
Fig. 3 is this utility model inferior lobe structural representation.
Among the figure: 1, go up leaf, 2, bayonet socket, 3, handle, 4, slot, 5, inferior lobe, 6, axle, 7, the zigzag adjusting rod.
The specific embodiment
Among Fig. 1, this utility model comprises that leaf 1, inferior lobe 5, two leaves are fastened as a duckbill barrel-like structure mutually.Last leaf 1 one side band handles 3 have slot 4 on the handle 3.There is bayonet socket 2 last leaf 1 both sides, and inferior lobe 5 both sides have to be convenient to open with the corresponding axle of last leaf 1 bayonet socket 6, two leaves to be closed, and the rear end is not sealed, and the working place is big.Inferior lobe 5 one sides are provided with zigzag adjusting rod 7, and the zigzag adjusting rod 7 of inferior lobe 5 passes from last leaf 1 slot 4, rotate zigzag adjusting rod 7, make the horizontal slot 4 that blocks of sawtooth of zigzag adjusting rod 7, and two leaves are stationary state up and down, are convenient to operation.When particularly cooperating peritoneoscope to lift the palace operation in the treatment, leaf 1 on the fine rotation, and mobile bayonet socket 2, two leaves are promptly opened, and can take out go up leaf, inferior lobe of the present utility model respectively, is not with device (this utility model) operation.
Among Fig. 2,1 is last leaf, and 2 is bayonet socket, and 3 is handle, and 4 is slot.
Among Fig. 3,5 is inferior lobe, and 6 is axle, and 7 is the zigzag adjusting rod.
Using method of the present utility model: during operation with this utility model closure, easily insert vagina, left side thumb press handle 3, regulate the scope that needs expansion, rotate zigzag adjusting rod 7, make the sawtooth of zigzag adjusting rod 7 block slot 4, to reach fixation, can check or treat, when particularly cooperating peritoneoscope to lift the palace operation in the treatment, push handle 3, rotate zigzag adjusting rod 7, make the sawtooth of zigzag adjusting rod 7 withdraw from slot 4, make the closed taking-up of two leaves or make the dislocation of two leaves withdraw from bayonet socket 2, take out the leaf of going up of the present utility model respectively, inferior lobe is not with device (this utility model) operation.
The plastics of this utility model available metal or hardness height, good toughness are made.
