Abstract
The utility model discloses a hook type nucleus removing device which comprises a handle. One end of the handle is fixedly connected with a thin hook, the length of which is suitable for cataract operations; the other end of the handle is provided with a clamping part. When a cataract operations is underway, after the eyelid is opened and the cornea rim is nicked, the thin hook can be used to hook the lens nucleus, the clamping part is convenient to exert a force to quickly hook out the lens nucleus so as to shorten the time of the whole operation and reduce the operation danger, and moreover, the back part of the thin hook is arc-shaped so that the endothelium of the cornea is not easy to be damaged, thereby being favorable for regaining the vision.
Description
Technical field
This utility model relates to a kind of medical instruments field, specifically is a kind of hook-type Kernel taking device that small incision cataract surgery is used that is used for.
Background technology
At present, treating cataractous main path is that ultrasonic emulsification is absorbed art and two kinds of methods of otch enucleation.It is to absorb after the nucleus lentis emulsifying that ultrasonic emulsification is absorbed art again, its equipment investment is big, surgery cost is high, and may damage corneal endothelium and influence Postoperative visual acuity and recover, and for very sophisticated nucleus lentis, treat if adopt ultrasonic emulsification to absorb art, operation is difficulty and complicated quite; The otch enucleation be with operative incision open suitably big, directly with the whole taking-up of nucleus lentis, traditional mode is that sophisticated nucleus lentis is drawn out or squeezed out with the circle spoon, causes the operating difficulty coefficient very big like this, and easily cause the corneal endothelium damage, be unfavorable for the recovery of Postoperative visual acuity.
The utility model content
The technical problems to be solved in the utility model provides a kind of safe and reliable, easy to operate hook-type Kernel taking device of cataract operation that makes.
For solving the problems of the technologies described above, the hook-type Kernel taking device that is provided comprises handle, and its construction features is: an end of described handle is connected with length and is applicable to the thin hook of doing cataract operation.
After adopting said structure, this hook-type Kernel taking device is fixed with the thin hook of moderate length, when carrying out cataract operation, open eyelid and with behind the cut-out of limbus corneae, available this thin hook hooks nucleus lentis, can conveniently firmly the quick hook of nucleus lentis can be gone out, thereby the time of shortening whole surgery is reduced the danger of performing the operation; And the back of thin hook is circular-arc, and the easy damaged corneal endothelium does not help the recovery of Postoperative visual acuity.
For convenient taking-up nucleus lentis, as further improvement of the utility model, the other end of described handle is provided with clamping part, can make surgical staff firmly convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The structural representation that Fig. 2 looks for Fig. 1 left side;
Among the figure: 1 is handle, and 2 is thin hook, and 3 is clamping part.
The specific embodiment
Hook-type Kernel taking device as depicted in figs. 1 and 2, it comprises columned handle 1, the front end of handle 1 is fixed with elongated thin hook 2, the length of thin hook 2 is applicable to does cataract operation, the head of thin hook 2 is a curved circular hook, and the rear end of handle 1 is provided with flat clamping part 3, and the surface of clamping part 3 is provided with anti-skidding screw thread, can make things convenient for surgical staff to control this hook-type Kernel taking device, thus the convenient nucleus lentis that firmly takes out.
