Screws are welded to the retracting arm and provided with fixing nuts. Compared with the prior art, the retractor for ophthalmologic operation has the advantages of reasonable design, simple structure, skillful conception, convenience in use and the like, and is capable of drawing much more muscular tissue together, leading operating visual field to be exposed sufficiently, improving operation efficiency and shortening operation time.
Description
Technical field
This utility model relates to technical field of medical instruments, the retractor that a kind of specifically ophthalmologic operation is special-purpose.
Background technology
At present in hospital clinically, need use retractor in the ophthalmologic operation, the retractor of prior art in use exists deficiency, and is fewer such as the quantity that retracts pawl; Sometimes can not be firm retract, use retracts slower, can not well expose the visual field, and it is less to expose the visual field sometimes; The muscular tissue of drawing in is few, and haemostatic effect is relatively poor, reduces the stability of operation technique; Influence carrying out smoothly of operation technique, reduce operation efficient, prolong operating time.
Summary of the invention
The technical assignment of this utility model is the deficiency that solves prior art, provides a kind of ophthalmologic operation simple in structure, easy to use to use retractor.
The technical scheme of this utility model realizes that by following mode this ophthalmologic operation is used retractor, comprises retracting pawl, drawing arm; Drawing arm is " U " shape; Retract pawl and be arranged on the both ends of drawing arm, on drawing arm, be welded with screw rod, screw rod is provided with the hold-down nut that matches.
The two ends of drawing arm are evenly distributed to be had and is no less than five and retracts pawl.
The beneficial effect that this utility model is compared with prior art produced is:
This ophthalmologic operation is simple in structure with retractor, and is easy to use, and on the basis of existing technology ophthalmologic operation done partly to improve with retractor, increases the quantity of traction pawl, can draw more muscular tissue in, improves operative stabilization property; The surgical field of view that enlarge to expose is welded with screw rod on drawing arm, can fix drawing arm like this, and is convenient when the medical worker is used, and retracts more accurately, improves operation efficient, reduces operating time.
