Description
Technical field
The utility model is related to scalpel technical fields, more particularly, to a kind of depth limit sawtooth scalpel.
Background technology
In Clinical Ophthalmology disease treatment, some ophthalmology diseases often will be by operative treatment, due to the solution of human eye
Cut open the reasons such as structure, surgical field of view be narrow, determine scalpel must small and flexible, with meet various different anatomic positions,
The needs that operative space is performed the operation.Existing ophthalmology scalpel is made of handle of a knife and cutter head, wherein the material of cutter head can divide
It it is two kinds, one of which is jewel material, sharp but of high cost, frangible, is easily damaged；Another kind is metal material, is mostly
Single side sword structure, is easy passivation, and service life is short.
On the other hand, existing scalpel, must be careful in surgical procedure due to not having position-limit mechanism and scale value,
In clinical resisting glaucoma operation, generally 1/3 thickness scleral flap is removed by scalpel, it is necessary to gradually deepen notch, not only
Operating time is extended, and operates and is also inconvenient；Work difficulty is increased to medical worker.
Therefore, the utility model proposes it is a kind of be conveniently replaceable, ophthalmology scalpel with stopper.
Utility model content
The utility model provide it is a kind of be conveniently replaceable, ophthalmology scalpel with stopper, with solve make in the prior art
The problem of being difficult to be accurately positioned with short life, operative incision depth.
The technical issues of the utility model is solved is realized using following technical scheme：
A kind of depth limit sawtooth scalpel, including handle of a knife, cutter head, wherein the cutter head is detachably arranged in described
The head of handle of a knife；
There is the outer edge of the cutter head blade, the blade to be made of the cutting edge of numerous arrangements that are serrated；
There is boss in the bit interface, the distance of end to the boss of the cutter head is 0.3mm~6mm.
The shape of the cutter head is triangle as a preferred technical solution, and the blade is distributed in the two of the cutter head
On a side.
Further, the angle of two blades at the top of the cutter head is 30 °~90 °.
The blade is arranged on the top of the cutter head as a preferred technical solution, and the shape of the blade is arc.
The blade is distributed on a side of the cutter head as a preferred technical solution, and the blade is in arc surfaced
Structure.
Further, the distance of the boss to the knife edge is 0.3mm~6mm.
The end of the cutter head has a screwed Cylindrical joint as a preferred technical solution, on the handle of a knife
With the screw shell to be matched by the Cylindrical joint, the cutter head is threadedly connected with handle of a knife.
The blade is double-sided blade as a preferred technical solution,；The cutting edge is arc-shaped or triangular structure.
The utility model has an advantageous effect in that：Simple in structure, easy to use, at low cost, sharp and service life is long,
Medical worker can accurately grasp operative incision depth, offer convenience for medical worker.
