Abstract
The utility model discloses descemet membrane dilaceration forceps, belonging to the technical field of medical instruments, and comprising a forceps handle, wherein the end of the forceps is provided with a buckling crank arm protruding upwards; and the end of the crank arm is provided with a fine-pointed forceps head buckling upwards. The descemet membrane dilaceration forceps have simple structure and convenience in use; the radian of the crank arm is designed specially for the dilaceration of the descemet membrane, thus facilitating operation during operation; and the descemet membrane dilaceration forceps is superior to crystal capsulorhexis forceps, can ensure the smoothness of the operation, and is suitable for being used in the corneal endothelial keratoplasty.
Description
Affiliated technical field
This utility model relates to a kind of operating theater instruments, and the special-purpose tweezers that especially use in the ophthalmologic operation belong to technical field of medical instruments.
Background technology
At present, corneal endothelium removes does not have the special-purpose tweezer that removes in the art, use common crystalline lens Tweezers for eye surgery to replace usually, because crystalline peplos is positioned at anterior chamber's bottom, the tweezer head all is bent downwardly with cranking arm, as shown in Figure 2.And the interface of descemet's membrane when removing is just in time opposite, and descemet's membrane is positioned at anterior chamber's top, uses common crystalline lens Tweezers for eye surgery to be inconvenient to operate.
The utility model content
At the problems referred to above, this utility model provides the special use of using in a kind of corneal endothelium transplantation to remove tweezer.
The technical scheme that its technical problem that solves this utility model adopts is: entocornea removes tweezer, comprises the tweezer handle, and the termination of tweezer handle is provided with the bending that raises up and cranks arm, and the termination of cranking arm is provided with the upwards pointed tweezer head of bending.
The anatomical position of corneal endothelium is positioned at anterior chamber's top in the foundation operation, and the upwards bending of cranking arm of the present utility model directs to cornea, and the tweezer head also stands upside down, and is convenient to remove descemet's membrane.
The beneficial effects of the utility model are, and are simple in structure, easy to use, owing to the radian of cranking arm is to remove at entocornea specially to design, make things convenient for the operation in the art, are better than the crystalline lens Tweezers for eye surgery, guarantee that operation carries out smoothly.Be suitable in the corneal endothelium transplantation, using.
Description of drawings
Fig. 1 is this utility model population structure sketch map;
Fig. 2 is existing crystalline lens Tweezers for eye surgery population structure structural representation.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
As Fig. 1, entocornea removes tweezer, comprises tweezer handle 1, and the termination of tweezer handle 1 is provided with the bending that raises up and cranks arm 2, and 2 the termination of cranking arm is provided with the upwards pointed tweezer head 3 of bending.
Remove tweezer and adopt stainless steel material to make, can titanizing alloy type anti-corrosion and attrition resistant material outside it.
Tweezer handle 1 is cylinder or prism, and radial dimension is 2.0-8.0mm, and long is 100-200mm.Best radial dimension is 3.5-5.0mm, and long is 140-160mm.
In the corneal endothelium transplant operation, make 3mm transparency cornea otch earlier, the anterior chamber is full of viscoelastic agent, then interior skin forceps is stretched into the anterior chamber, punctures descemet's membrane at posterior surface of cornea, starts a tissue flap, lives with the tweezer head-clamp then, and the descemet's membrane annular of pathological changes is removed.After this implant descemet's membrane graft or other substituting grafts of donor.
