Abstract

The utility model discloses a kind of ophthalmology scalpels with angle positioning function, including knife handle, set on the bending-type cutter head of knife handle end.Bending-type cutter head includes the interconnecting piece being connected with knife handle head, the cutting part for upwardly extending set on the sloped-end of interconnecting piece setting, and cutting part is arranged at an angle with interconnecting piece.Cutting part has the positive knife face opposite with knife handle.Scalpel further includes the locating piece on knife handle, and the extending direction of locating piece and the extending direction of positive knife face are perpendicular.A kind of ophthalmology scalpel with angle positioning function of the utility model has a locating piece perpendicular to knife face, doctor can be allowed to enter cornea angle to cutter head in surgical procedure and positioned, and increases operative incision angle accuracy, reduces operation risk.

Description

A kind of ophthalmology scalpel with angle positioning function

Technical field

The utility model relates to a kind of ophthalmology scalpel more particularly to a kind of ophthalmologic operations with angle positioning function Knife.

Background technique

When performing the operation to patient's cornea, the cutter head that doctor holds the knife handle control scalpel of scalpel is enterprising in cornea Row notch, in the prior art, notch is generally parallel to cornea, in order to which other instruments enter in notch.Currently on the market The knife handle of scalpel be all dermatoglyph design, doctor can only control the angle that cutter head enters cornea by personal operating experience Degree.Therefore, insufficient or when being not in good state in doctors experience, it is easy to notch to be cut askew, deleterious effect is generated to operation.

Utility model content

The purpose of the utility model is to provide a kind of ophthalmology scalpels with angle positioning function, change to scalpel Into so that user use cornea is entered to cutter head in surgical procedure angle position, increase the accurate of cut angle Property.

In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of ophthalmology with angle positioning function Scalpel, the scalpel include knife handle, the bending-type cutter head set on the knife handle end, and the bending-type cutter head includes and institute It states interconnecting piece that knife handle head is connected, upwardly extend the cutting part of setting set on the sloped-end of the interconnecting piece, it is described to cut It cuts portion to be arranged at an angle with the interconnecting piece, the cutting part has the positive knife face opposite with the knife handle, the operation Knife further includes the locating piece on the knife handle, and the extending direction of the locating piece and the extending direction of the positive knife face mutually hang down Directly.

Preferably, the range of front end face of the front end face of the locating piece apart from the knife handle end are as follows: 8mm to 20mm.

Further, front end face 10mm of the front end face of the locating piece apart from the knife handle end.

Preferably, the altitude range of the locating piece are as follows: 3mm to 8mm.

Further, the height of the locating piece is 5mm.

Preferably, the cross section of the locating piece is rectangle or semicircle.

Preferably, the knife handle head is arranged in truncated cone-shaped, has the bus perpendicular with the positive knife face, described fixed The extending direction of position block is parallel with the extending direction of bus.

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 ophthalmology scalpel with angle positioning function of type has a locating piece perpendicular to knife face, doctor can be allowed to exist Enter cornea angle to cutter head when surgical procedure to position, increases operative incision angle accuracy, reduces operation risk.

Detailed description of the invention

Attached drawing 1 is the schematic top plan view of the ophthalmology scalpel with angle positioning function of the utility model；

Attached drawing 2 is the schematic elevation view of the ophthalmology scalpel with angle positioning function of the utility model.

Wherein: 1, knife handle；2, bending-type cutter head；21, interconnecting piece；22, cutting part；3, locating piece.

Specific embodiment

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

Referring to attached drawing 1 and a kind of ophthalmology scalpel with angle positioning function shown in Fig. 2, including knife handle 1, it is set to knife The bending-type cutter head 2 of 1 end of handle.Bending-type cutter head 2 includes the interconnecting piece 21 being connected with knife handle head, set on interconnecting piece 21 Sloped-end upwardly extends the cutting part 22 of setting, and cutting part 22 is arranged at an angle with interconnecting piece 21, and cutting part 22 has The positive knife face opposite with knife handle 1.Scalpel further includes the locating piece 3 on knife handle 1, the extending direction of locating piece 3 and positive knife The extending direction in face is perpendicular.

The range of front end face of the front end face of locating piece 3 apart from 1 end of knife handle are as follows: 8mm to 20mm, preferred distance are 10mm.The altitude range of locating piece 3 are as follows: 3mm to 8mm, preferred height are 5mm.

The cross section of locating piece 3 can be the various shapes such as rectangle, semicircle.

As an implementation, the end of handle 1 is arranged in truncated cone-shaped, has the bus perpendicular with positive knife face, The extending direction of locating piece 3 and the extending direction of bus are parallel, it is preferred that locating piece 3 is set on the bus.

When user carries out ophthalmologic operation using this scalpel, user can press...with one's finger locating piece 3, make to position Block 3 is perpendicular to cornea, because locating piece 3 perpendicular to cutting part 22, in a disguised form makes cutting part 22 be parallel to cornea, so that doctor Life, by being reference with locating piece 3, cutter head 2 can be positioned into cornea angle, increase operation and cut in surgical procedure Bicker degree accuracy reduces operation risk.

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.
