Description

A kind of scalpel and its cutter head

Technical field

The utility model relates to a kind of scalpel and its cutter heads.

Background technique

It, can be to doctor in the case where cutter head is not sharp enough when doctor carries out puncture incision to patient's eyeball using scalpel Raw surgical procedure brings great inconvenience, and easily causes edge of a knife out-of-flatness, so that notch restores poor, is easy after surgery to patient Bring unnecessary pain.In the prior art, using blade double-side grinding technology, make point of a knife that taper be presented, readily penetrate through tissue, Achieve the purpose that be easier to production notch.But since its tip shapes is the thin pyramid shape in thick middle both sides as shown in Figure 1, There are still the intermediate regions changed greatly between the knife ridge 2 in two face of cutter head, are easy to cause puncture difficulty, notch out-of-flatness The problems such as.

Utility model content

The purpose of the utility model is to provide a kind of cutter head of scalpel, region of variation is smaller between the knife ridge of cutter head, makes It is more smooth to obtain the edge of a knife.

In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of cutter head of scalpel, including blade, Knife ridge, knife face and point of a knife, the blade are located at the cutter head two sides, and the point of a knife is tapered, the blade and the common structure of knife ridge At the incline of the point of a knife, the sum of the knife ridge is greater than 2.

Preferably, axis connecting line symmetrical setting of the point of a knife along blade described in two sides.

Further, the knife ridge positioned at described blade the same side is along the symmetrical setting in the central axes of the point of a knife.

Further, the sum of the knife ridge is 4.

Further, the sum of the knife ridge is 6.

Further, the sum of the knife ridge is 8.

Further, the knife ridge is equipped with rounded corner.

Further, the both ends of the rounded corner extend respectively to blade described in two sides.

The another object of the utility model is to provide a kind of scalpel with above-mentioned surgical knife head.

In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of scalpel, including knife handle, the hand Art knife further includes cutter head as described above.

Due to the application of the above technical scheme, the utility model has the advantage that this is practical new compared with prior art A kind of scalpel and its cutter head of type, region of variation is smaller between the knife ridge of cutter head, and the slope of cutter head is lower, blade more cutting edge of a knife or a sword Benefit, so that notch is more smooth.It can reduce venipuncture difficulty using changing knife head for surgical and carrying out operation, reduce doctor's operation difficulty, Reduce patient's postoperative complications.

Specific embodiment

The technical solution of the utility model is further elaborated with reference to the accompanying drawings and examples.

Referring to a kind of attached drawing 2 to attached cutter head of scalpel shown in fig. 5, including be located at the blades 1 of cutter head two sides, knife ridge 2, Knife face 3 and point of a knife 4.Point of a knife 4 is tapered, and blade 1 and knife ridge 2 collectively form the incline of point of a knife 4, and wherein the sum of knife ridge 2 is greater than 2 Item.The slope of each knife ridge 2 is respectively less than the slope of the knife ridge 2 in the point of a knife of rectangular pyramid in the prior art 4 as shown in Fig. 1.It is excellent Choosing, point of a knife 4 is located at the symmetrical setting of knife ridge 2 of 1 two sides of blade along the symmetrical setting of axis connecting line of two sides blade 1, So that notch two sides are symmetrical also more smooth；Further, positioned at 1 the same side of blade knife ridge 2 along point of a knife 4 central axes phase It is symmetrical arranged, so that the structure for being located at the blade 1 of cutter head two sides is identical, it is more convenient to use.

Embodiment 1:

In the present embodiment, the sum of knife ridge 2 is 4, that is, being located at 4 side of point of a knife has 2 knife ridges 2, and point of a knife 4 is in hexagonal pyramid Shape.Point of a knife 4 is symmetrical arranged along the axis connecting line of two sides blade 1, and is located at the axis of the knife ridge 2 along point of a knife 4 of 4 the same side of point of a knife The symmetrical setting of line.In this example, the slope of each knife ridge 2 is respectively less than in the point of a knife of rectangular pyramid in the prior art 4 as shown in Fig. 1 Knife ridge 2 slope.Region of variation is smaller between the knife ridge 2 of 1 two sides of blade, and blade 1 is sharper, so that notch is more It is smooth.Carrying out operation using the knife head for surgical can reduce venipuncture difficulty, reduce doctor's operation difficulty, reduce patient's complicated by postoperative Disease.

Embodiment 2:

In the present embodiment, the sum of knife ridge 2 is 6, that is, being located at 4 side of point of a knife has 3 knife ridges 2, and point of a knife 4 is in eight pyramids Shape.Point of a knife 4 is symmetrical arranged along the axis connecting line of two sides blade 1, and is located at the axis of the knife ridge 2 along point of a knife 4 of 4 the same side of point of a knife The symmetrical setting of line.In this example, the slope of each knife ridge 2 is respectively less than in the point of a knife of rectangular pyramid in the prior art 4 as shown in Fig. 1 Knife ridge 2 slope.Region of variation is smaller between the knife ridge 2 of 1 two sides of blade, and blade 1 is sharper, so that notch is more It is smooth.Carrying out operation using the knife head for surgical can reduce venipuncture difficulty, reduce doctor's operation difficulty, reduce patient's complicated by postoperative Disease.

Embodiment 3:

In the present embodiment, the sum of knife ridge 2 is 8, that is, being located at 4 side of point of a knife has 4 knife ridges 2, and point of a knife 4 is in ten pyramids Shape.Point of a knife 4 is symmetrical arranged along the axis connecting line of two sides blade 1, and is located at the axis of the knife ridge 2 along point of a knife 4 of 4 the same side of point of a knife The symmetrical setting of line.In this example, the slope of each knife ridge 2 is respectively less than in the point of a knife of rectangular pyramid in the prior art 4 as shown in Fig. 1 Knife ridge 2 slope.Region of variation is smaller between the knife ridge 2 of 1 two sides of blade, and blade 1 is sharper, so that notch is more It is smooth.Carrying out operation using the knife head for surgical can reduce venipuncture difficulty, reduce doctor's operation difficulty, reduce patient's complicated by postoperative Disease.

Embodiment 4:

Referring to the cutter head of attached scalpel shown in fig. 5, in the present embodiment, knife ridge 2 is equipped with rounded corner, so that using the hand When art knife is performed the operation, notch is more smooth.Preferably, the both ends of rounded corner extend respectively to two sides blade 1, point of a knife 4 Cross section is arc-shaped, and to reduce the slope of cutter head, blade 1 is sharper, so that notch is more smooth.Using changing knife head for surgical Carrying out operation can reduce venipuncture difficulty, reduce doctor's operation difficulty, reduce patient's postoperative complications.

The cutter head of the scalpel of embodiment 1 to embodiment 4 is installed to can be formed on the scalpel knife handle being matched therewith One complete scalpel, the relatively existing knife head for surgical slope of the cutter head of the scalpel is lower, and blade 1 is sharper, so that Notch is more smooth.It can reduce venipuncture difficulty using changing knife head for surgical and carrying out operation, reduce doctor's operation difficulty, reduce patient Postoperative complications.

The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention. All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it It is interior.
