Abstract
The utility model relates to a cutter head of an eye operating cutter. The edge at the end part of the cutter head is sharp; the bending position of at least one side surface of the cutter head, close to the edge of the end part, is provided with an edge of a second end part; the width of the root part of the edge of the second end part is less than that of the side surface of the cutter head; and a limit step is formed between the root part of the edge of the second end part and the side surface of the cutter head. The cutter head has simple structure, is not only applicable to sectioning tissues in a horizontal plane, but also applicable to sectioning tissues in a vertical plane, and especially can limit sectioning depth.
Description
Technical field
This utility model relates to a kind of ophthalmology scalpel.
Background technology
Existing a kind of ophthalmology scalpel as shown in Figure 4, comprises handle of a knife 10 and cutter head 20, described cutter head 20 is connected described handle of a knife 10 1 ends by connector 30, and the end blade of described cutter head 20 is pointed, and described blade is two-sided gradient, certainly, also can make the structure that described blade is the single face gradient.This class scalpel is used cataractous excision mostly in ophthalmologic operation, this scalpel is not in-problem for cataractous horizontal plane dissecing tissue, but, for in same operation, need vertical to dissect tissue if run into, especially the vertical that needs to dissect the degree of depth surely dissects tissue, and it is very inconvenient to bring to user.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above, provides a kind of simple in structure to society, is not only applicable to horizontal plane and dissects tissue, but also be applicable to that vertical dissects tissue, especially can limit the ophthalmology scalpel that dissects the degree of depth.
The technical solution of the utility model is: design a kind of ophthalmology scalpel, comprise handle of a knife and cutter head, described cutter head is connected described handle of a knife one end, the end blade of described cutter head is pointed, at least one side bending part at the close end of described cutter head blade is provided with the second end blade, the heel width of described the second end blade constitutes limited step less than this lateral width of cutter head between the heel of described the second end blade and the side of cutter head.
On described cutter head another side, also be provided with, and the second end edge length is less than side length perpendicular to this lateral the second end blade near the end blade; The heel width of described the second end blade constitutes limited step less than this lateral width of cutter head between the heel of described the second end blade and the side of cutter head.
This utility model is owing at least one side of having adopted described cutter head near the end blade is provided with perpendicular to the side, and the second end edge length is less than the second end blade of side length; The heel width of described the second end blade is less than the lateral width of cutter head, constitute the structure of limited step between the heel of described the second end blade and the side of cutter head, so the utlity model has simple in structure, be not only applicable to horizontal plane and dissect tissue, but also be applicable to that vertical dissects tissue, especially can limit the advantage of dissecing the degree of depth.

The specific embodiment
For making the auditor more be expressly understood structure of the present utility model, cooperate graphic being described as follows now:
See also Fig. 1, Fig. 1 is the perspective view of a kind of embodiment of the present utility model.It is a kind of ophthalmology scalpel, comprise handle of a knife 1 and cutter head 2, described cutter head 2 is connected described handle of a knife 1 one ends by cutter head connector 3, the end blade 21 of described cutter head 2 is pointed, side 22 bending parts at described cutter head 2 close end blades 21 are provided with the second end blade 4, the heel width of described the second end blade 4 is less than side 22 width of cutter head, constitute limited step 23 between the heel of described the second end blade 4 and the side of cutter head 22, the height of described the second end blade 4 is preferably 0.3mm, like this, when using the second end blade 4 to dissect to organize, limited step 23 just can guarantee that 4 of the second end blades deeply organize 0.3mm, plays the effect that limits the second end blade 4 degree of depth.
See also Fig. 2 and Fig. 3, Fig. 2 is the three-dimensional structure for amplifying sketch map of the another kind of cutter head of this utility model.Fig. 3 is the three-dimensional structure for amplifying sketch map of another cutter head of this utility model.As can be seen from Figures 2 and 3, on the another one side of described cutter head 2, also be provided with one, and the second end edge length is less than the second end blade 41 of side length perpendicular to the side; The heel width of described the second end blade 41 constitutes limited step less than the lateral width of cutter head between the heel of described the second end blade and the side of cutter head.
