SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the prior art has a flared vaginal dilator which can not clearly expose the operation visual field.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a vagina retractor, includes first expansion cover and second expansion cover, first expansion cover and second expansion cover are the arc, the one end fixedly connected with second shell fragment of first expansion cover, the first shell fragment of one end fixedly connected with of second expansion cover, the inner chamber of second expansion cover is inserted to the tip of second shell fragment, the inner chamber of first expansion cover is inserted to the tip of first shell fragment, multichannel screw thread draw-in groove has evenly been seted up to the outer wall of first shell fragment and second shell fragment, the outer wall homogeneous body shaping of first expansion cover and second expansion cover is equipped with adjusting sleeve, it is equipped with adjusting bolt to rotate in adjusting sleeve's the inner chamber, adjusting bolt's outer wall is provided with to the T type screw thread of interlock with the screw thread draw-in groove, the equal fixedly connected with expansion piece of outer wall of first expansion cover and second expansion cover.
The expansion piece is an arc-shaped metal piece, and a plurality of strip-shaped through holes are uniformly formed in the outer wall of the expansion piece.
The end part of the adjusting bolt is provided with a pentagonal counter bore, a link rod matched with the counter bore in shape is inserted into the counter bore, and the end part of the link rod is fixedly connected with a knob.
The utility model provides a vagina retractor, beneficial effect lies in: through setting up first expansion cover, the second expands the cover, first shell fragment and second shell fragment, first expansion cover, the second expands and sheathes in and all connects the expansion piece, when using this retractor, at first clean the retractor, then insert the patient vagina with the expansion piece, then rotatory knob, first shell fragment and second shell fragment follow first expansion cover under adjusting bolt's drive, stretch out in the second expansion cover, first shell fragment and second shell fragment drive two expansion pieces and expand the function that realizes retracting in the in-process that stretches out, after retracting, its outer mouthful keeps the parallel and level with interior mouthful, the outer mouthful is little can not appear, the big condition of interior mouthful, can be more clear expose the operation field of vision, doctor's the operation degree of difficulty has been reduced, patient's misery has been alleviateed.
Drawings
Fig. 1 is a schematic structural view of a vaginal retractor according to the present invention;
fig. 2 is a side view of a vaginal retractor according to the present invention.
In the figure: the expansion device comprises a first expansion sleeve 1, a first elastic sheet 2, a second expansion sleeve 3, a 4T-shaped thread, an adjusting sleeve 5, an adjusting bolt 6, a connecting rod 7, a knob 8, a second elastic sheet 9, an expansion sheet 10, a through hole 11 and a thread clamping groove 12.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a vaginal retractor, including first expansion cover 1 and second expansion cover 3, first expansion cover 1 and second expansion cover 3 are the arc, the one end fixedly connected with second shell fragment 9 of first expansion cover 1, the one end fixedly connected with first shell fragment 2 of second expansion cover 3, the inner chamber of second expansion cover 3 is inserted to the tip of second shell fragment 9, the inner chamber of first expansion cover 1 is inserted to the tip of first shell fragment 2, multichannel screw thread draw-in groove 12 has evenly been seted up to the outer wall of first shell fragment 2 and second shell fragment 9, the equal integrated into one piece of outer wall of first expansion cover 1 and second expansion cover 3 is equipped with adjusting sleeve 5, it is equipped with adjusting bolt 6 to rotate in adjusting sleeve 5's the inner chamber, adjusting bolt 6's outer wall is provided with and screws with screw thread draw-in groove 12 to the T type 4 of interlock, the equal fixedly connected with of outer wall of first expansion cover 1 and second expansion cover 3 expands piece 10.
The expansion pieces 10 are all arc-shaped metal pieces, and a plurality of strip-shaped through holes 11 are uniformly formed in the outer walls of the expansion pieces 10. The end part of the adjusting bolt 6 is provided with a pentagonal counter bore, a connecting rod 7 matched with the counter bore in shape is inserted into the counter bore, the end part of the connecting rod 7 is fixedly connected with a knob 8, and the arranged counter bore and the connecting rod 7 structure enable the knob 8 to be taken down from the adjusting sleeve 5 after the retracting angle is adjusted, so that the knob is prevented from obstructing the visual field in the operation process.
