Abstract
The utility model provides a lachrymal sac retractor, which comprises a retracted arm, a retracted palm and a retracted claw; two retracted arms are articulated together. The utility model is characterized in that: the retracted palm is articulated with the front part of the retracted arm; the utility model has a simple structure and a simple operation, which can be opened and closed rapidly, and is steady and safe.
Description
Technical field
This utility model belongs to medical apparatus and instruments, is a kind of lacrimal sac retractor.
Background technology
The present lacrimal sac retractor that uses in the ophthalmologic operation, the folding that retracts the palm is controlled by drawing arm tail end screw rod, in the use, the process that retracts is slow, retract two drawing arm rear portions, fixing back upwarp, unsettled, less stable influences operation technique.
Summary of the invention
The purpose of this utility model is: design a kind of rational in infrastructure, lacrimal sac retractor that folding speed is fast, safe in utilization.
This utility model comprises drawing arm, retracts the palm, retracts pawl, and two drawing arms are hinged and connected, and its technical scheme is: retract the palm and be hinged on the drawing arm front end; Fixture is housed on the drawing arm, fixture comprises hold-down screw and two stators, two stators that are hinged on two drawing arms link to each other by hold-down screw, one of them stator is provided with hollow groove: the drawing arm tail end is equipped with elastic locking device, elastic locking device is the V-arrangement preloading spring, and the two ends of preloading spring are pressed on the outside of two drawing arms.
The beneficial effects of the utility model are: the utility model of this structure, rational in infrastructure, easy and simple to handle, folding in use is fast, stability and safety.
Description of drawings
Fig. 1 is this utility model example structure sketch map;
Wherein, 1, retract the palm, 2, drawing arm, 3, retract pawl, 4, rotating shaft, 5, hold-down screw, 6, stator, 7, the hollow stator, 8, hollow groove, 9, bolt, 10, preloading spring.
The specific embodiment
As shown in Figure 1, retract the palm 1 and be hinged on drawing arm 2 front ends by rotating shaft 4,1 move up and down so that retract the palm, avoid drawing arm rear portion, fixing back upwarp, unsettled, in the operation, retractor is placed operation place, strut two drawing arms 2, two and retract the palm 1 field of operation strutted, fixedly retract and slap 1, rotate drawing arm 2 and be attached at outside the field of operation, it is firm to stablize after making retractor fixing.
Hinged securement sheet 6 on one drawing arm, hinged hollow stator 7 on another drawing arm, have hollow groove 8 on the hollow stator 7, stator 6 links to each other by hold-down screw 5 with hollow stator 7, two drawing arms are hinged and connected by bolt 9, be arranged with V-arrangement preloading spring 10 on the bolt 9, the two ends of preloading spring 10 are pressed on the outside of two drawing arms.
This structure makes not only that to retract palm folding speed fast, flicks the excessive damage eyes of amplitude but also can avoid retracting the palm, reaches safety, result of use efficiently.
