Abstract
The utility model provides an ophthalmology dedicated scalpel for medical care, composed of a knife blade and a knife frame which is composed of a knife blade fixing structure and a knife blade adjusting structure. The knife blade fixing structure is composed of a knife blade collet, a knife blade locking nut and a guide pin; The knife blade adjusting structure is composed of a vernier nut and an adjusting screw. When doing operations, the utility model can adjust the depth of the knife blade optionally according to the depth of the operative incision, thus exactly defining the operative incision, suitable for various ophthalmological operations.
Description
This utility model is the invention about the ophthalmic operating set of medical and health use.
At present, the scalpel of using when the ophthalmologist performs an operation generally is made up of blade and handle of a knife, time spent snaps in handle of a knife bayonet socket place with blade and can use, though convenient, be difficult for grasping the degree of depth that eyeball tissue cuts, need sensation cutting, thereby influenced therapeutic effect by the patient.
In view of the problem that existing scalpel exists, the purpose of this utility model provides a kind of adjustable multifunctional ophthalmology scalpel.
Concrete solution of the present utility model is that scalpel is made up of blade and knife rest.Blade is a microknife, and knife rest is made up of fixed blade structure and adjusting blade structure.Fixed blade structure is locked the blade nut by insert cartridges, and the guide finger fourth is formed; Regulate blade structure by fine-tuning nut, adjusting screw(rod) is formed.The insert cartridges head has the cross crack, the special-purpose blade of clamping, and middle part and the assembling of guide finger fourth, tailing screw flight is connected with locking blade nut.Fine-tuning nut, the locking nut turn-knob is outside the adjusting screw(rod) wall.The adjusting screw(rod) afterbody has a groove, and locking blade nut links to each other with the afterbody of insert cartridges by screw thread, and borrows the groove assembly of rotation fourth silk and adjusting screw(rod).Because the effect of fourth silk is connected as a single entity adjusting screw(rod) and insert cartridges, forces the insert cartridges axially-movable.At last safe locating rod is packed in the pipe of the forward hole of knife rest.
Below in conjunction with accompanying drawing this utility model is described further.
Accompanying drawing is a general assembly drawing of the present utility model
As shown in the figure, this multi-functional fine setting ophthalmology scalpel is made up of blade and knife rest.Knife rest is by safety locating rod (1), guide finger fourth (2), and fine-tuning nut (3), locking nut (4), adjusting screw(rod) (5), locking blade nut (6), insert cartridges (7), knife rest (8), guiding fourth silk (9), rotation fourth silk (10) is formed.Insert cartridges (7) head has cross crack, fixturing blade, and middle part and guide finger fourth (2) assembling, tailing screw flight is connected with locking blade nut (6).Fine-tuning nut (3), locking nut (4) turn-knob is outside adjusting screw(rod) (5) wall, adjusting screw(rod) is hollow tubular shape, afterbody has a groove, locking blade nut (6) links to each other by the afterbody of screw thread and insert cartridges, and the groove assembly of borrowing rotation fourth silk (10) and adjusting screw(rod), because the effect of guide finger fourth (2) is connected as a single entity adjusting screw(rod) (5) and insert cartridges (7).Safe locating rod (1) is packed in the pipe of the forward hole of knife rest.
During use, with special blade, in the crack of the insert cartridges of packing into, rotational lock blade nut, blade is clamped, because the effect of guide finger fourth, during rotation, blade can not rotate, thereafter according to the needs of the operative incision degree of depth, regulate fine-tuning nut, screw locking nut subsequently, to guarantee that blade is difficult for being shifted, becoming flexible in the art.
This utility model is simple in structure, makes easilier, and blade is sharp-pointed, can be according to the degree of depth of operative incision, and arbitrarily the degree of depth of adjustable blade can limit operative incision accurately.
This utility model is applicable to does the multiple operation of ophthalmology.
