Abstract
The utility model discloses a pair of small surgical scissors for deep eyes, consisting of a cone-tube shaped handle (1) and a fixed scissors blade (2). The small surgical scissors for deep eyes is characterized in that an upper movable scissors blade (5) is fixed on the rear end of the fixed scissors blade (2); the rear end inside the cavity of the cone-tube shaped handle (1) is provided with a pulley (6); an opening trigger handle (7) of the upper movable scissors blade (5) is fixed on a hole disposed on the side wall of the cone-tube shaped handle (1); one end of a super-high molecular weight polyethylene fiber yarn (8) is fixed on the rear end of the movable scissors blade (5), and the other end bypasses the pulley (6) and then is fixed on the inner end of the opening trigger handle (7); one end of a super-high molecular weight polyethylene fiber yarn (8') is fixed on the movable scissors blade (5), and the other end is connected with a tension spring (9) fixed on the inner wall of a handle (3). The pair of surgical scissors is easy to be inserted in the deep eyes because of the small volume, adopts the cone-tube-shaped handle because of the power transmission by the superfine fiber and has simple structure and flexible operation..
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of the trickle operating scissors in depths.
Background technology
When ophthalmology was made detachment of retina operation or operation on vitreous, because operative site is darker, the art open country was less, need carry out at microscopically, and this operation, it is meticulous to perform the operation, and otch is small.When incised tissue or removal lesion tissue, still use common little shears or scalpel at present, cause otch to enlarge, do not reach trickle purpose.
Summary of the invention
The purpose of this utility model be to provide a kind of otch small, use flexibly, be particularly suitable for carrying out the trickle operating scissors in eye depths of a depths operation at microscopically.
For reaching above purpose, the technical scheme that this utility model adopted is: the trickle operating scissors in this depths, by the awl tubular handle, the fixed blade sheet constitutes, fixed blade sheet knife back portion seat end is fixed as one with the sharp-crested wall of awl tubular handle, the fixed blade sheet becomes the angle of 20-80 degree with the awl tubular handle, the fixedly connected upper handle of seat end in the awl tubular handle, handle is opposite with the direction of fixed blade sheet, and become the angle of 90-115 degree with the awl tubular handle, it is characterized in that fixing the movable scissors sheet by bearing pin in the rear end of fixed blade sheet, be provided with pulley in awl tubular handle intracavity rear end, fix the handle of dehiscing to play the part of of going up the movable scissors sheet by fixed axis on its areole, fix an end of a superhigh molecular weight polyethylene fibers silk in the movable scissors sheet rear end at bearing pin rear portion, the other end of this root superhigh molecular weight polyethylene fibers silk is walked around pulley and is fixed on the inner of dehiscing to play the part of handle, an end of another root superhigh molecular weight polyethylene fibers silk on fixing on the forward movable scissors sheet of bearing pin, the other end of another root superhigh molecular weight polyethylene fibers silk is connected with extension spring on being fixed on the handle inwall.
This utility model is also implemented by following measure: at the fixing top shoe of extension spring inner end, slide block stretches out from the bar hole on the handle wall; Described superhigh molecular weight polyethylene fibers silk is the fiber that a kind of intensity is very high, diameter is superfine, is a kind of well known materials.
The beneficial effects of the utility model are: with at present in the delicate procedure of ophthalmology deep employed operating scissors compare, volume is little, particularly shears the position and since can do very little, so stretch into easily; Because superfine superhigh molecular weight polyethylene fibers silk has been adopted in the transmission of power, so it is very thin that the awl tubular handle can be done.And simple in structure, flexible operation, easy to use.Can be widely used in ophthalmology deep microsurgery.
Description of drawings
Fig. 1, for axis of no-feathering of the present utility model to analysing and observe enlarged diagram.
The specific embodiment
Make this utility model with reference to Fig. 1.The trickle operating scissors in this depths, by awl tubular handle 1, fixed blade sheet 2 constitutes, fixed blade sheet 2 knife back portion seat ends are fixed as one with the sharp-crested wall of awl tubular handle 1, the angle of fixed blade sheet 2 and 1 one-tenth 20-80 degree of awl tubular handle, the fixedly connected upper handle 3 of seat end in awl tubular handle 1, handle 3 is opposite with the direction of fixed blade sheet 2, and with the angle of awl tubular handle 1 one-tenth 90-115 degree, it is characterized in that fixing movable scissors sheet 5 by bearing pin 4 in the rear end of fixed blade sheet 2, be provided with pulley 6 in awl tubular handle 1 intracavity rear end, fix the handles 7 of dehiscing to play the part of of going up movable scissors sheet 5 by fixed axis 12 on its areole, fix an end of a superhigh molecular weight polyethylene fibers silk 8 in movable scissors sheet 5 rear ends at bearing pin 4 rear portions, the other end of this root superhigh molecular weight polyethylene fibers silk 8 is walked around pulley 6 and is fixed on the inner of dehiscing to play the part of handle 7, when the handle 3 usefulness forefingers of holding with a firm grip are played the part of when dehiscing to play the part of handle 7, because the pulling of this root superhigh molecular weight polyethylene fibers silk 8, make movable scissors sheet 5 open mouth with respect to fixed blade sheet 2, another root superhigh molecular weight polyethylene fibers silk 8 on fixing on the bearing pin 4 forward movable scissors sheets 5 ' an end, another root superhigh molecular weight polyethylene fibers silk 8 ' the other end be connected with extension spring 9 on being fixed on handle 3 inwalls, when movable scissors sheet 5 is dehisced with respect to fixed blade sheet 2, extension spring 9 another root superhigh molecular weight polyethylene fibers silk 8 ' pulling under stretched, when unclamping when dehiscing to play the part of handle 7, under the effect of extension spring 9, movable scissors sheet 5 is remained silent with respect to fixed blade sheet 2, realizes the shearing to tissue.
At the fixing top shoe 10 of extension spring 9 inner ends, slide block 10 stretches out from the bar hole 11 on handle 3 walls, after movable scissors sheet 5 is remained silent with respect to fixed blade sheet 2, if yet tissue is not cut off, can play the part of movable slider 10, continue to make movable scissors sheet 5 to remain silent, can cut off tissue with respect to fixed blade sheet 2; Described superhigh molecular weight polyethylene fibers silk 8,8 ' be the fiber that a kind of intensity is very high, diameter is superfine, be a kind of well known materials.
