The present invention is for solving the uncontrollable problem of current scalpel angle, for herein is provided a kind of adjustable-angle scalpel, comprise handle of a knife and blade, described handle of a knife is provided with installing plate, described installing plate is provided with multiple front card column and single rear card column, described front card column be after card column be the circumferential arrangement in the center of circle, described blade is provided with two hole clippings, the wedge structure of described hole clipping to be front-end and back-end be all arc surface.
As preferably, described front card column and rear card column comprise lower cylinder and limited block, and described limited block is arranged on lower cylinder.
As preferably, described handle of a knife cross section is ellipsoidal structure.
As preferably, described handle of a knife is provided with anti-skidding adhesive tape.
The invention has the beneficial effects as follows: structure of the present invention is simple, different card columns can be utilized to carry out coordinating the angle of adjustable blade, doctor can be facilitated to carry out the operation needs of various angle, improve operation precision, reduce the probability of malpractice.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is schematic perspective view of the present invention;
Fig. 2 is schematic front view of the present invention;
Fig. 3 is that schematic diagram is looked on a left side for handle of a knife;
Fig. 4 is the schematic front view of blade;
In figure: 1, handle of a knife; 1.1, installing plate; 1.2, front card column; 1.3, rear card column; 1.31, lower cylinder; 1.32, limited block; 2, blade; 2.1, hole clipping; 3, anti-skidding adhesive tape.
Detailed description of the invention
All features disclosed in this description, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this description (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
A kind of adjustable-angle scalpel as depicted in figs. 1 and 2, comprise handle of a knife 1 and blade 2, described handle of a knife 1 is provided with installing plate 1.1, described installing plate 1.1 is provided with multiple front card column 1.2 and single rear card column 1.3, described front card column 1.2 be after card column 1.3 be the circumferential arrangement in the center of circle, as shown in Figure 4, described blade 2 is provided with two hole clippings 2.1, the wedge structure of described hole clipping 2.1 to be front-end and back-end be all arc surface.
As shown in Figure 3, described front card column 1.2 and rear card column 1.3 comprise lower cylinder 1.31 and limited block 1.32, and described limited block 1.32 is arranged on lower cylinder 1.31.
Described handle of a knife 1 cross section is ellipsoidal structure.
Described handle of a knife 1 is provided with anti-skidding adhesive tape 3.
The diameter of the rear end circular arc of described hole clipping 2.1 is identical with the diameter of limited block 1.32, and the front end circular arc of described hole clipping 2.1 is less than rear end arc diameter.
In use, doctor only needs as required the hole clipping 2.1 on blade 2 to be aimed at front and back card column and puts into, and then by blade 2 pusher, hole clipping 2.1 engages with lower cylinder 1.31, and during operation, the effect of counteracting force makes blade more block tightlier can not to drop.
Structure of the present invention is simple, different card columns can be utilized to carry out coordinating the angle of adjustable blade, doctor can be facilitated to carry out the operation needs of various angle, improve operation precision, reduce the probability of malpractice.
The present invention is not limited to aforesaid detailed description of the invention.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
