Stitch scissors, angular bandage scissors, meninx/nerve cut, microscissors, eye scissors, corneal scissors, membranaceous cataract or glaucoma are cut, small-beam scissor, micro- iris
It cuts and is cut with stapes arch of foot.Tissue shear is mostly curved scissors, sharp keen and fine, cuts off tissue for dissecting, cutting or separate.It is usually shallow
Curved scissors is used in portion's surgical procedure staight scissors, deep operation operation.
The Chinese patent that Authorization Notice No. is CN204295705U, authorized announcement date is on 04 29th, 2015 discloses one
Kind curved formula tissue scissors, including straight-arm and crank arm, the straight-arm and front end of cranking arm are hinged, and the front end of the straight-arm is equipped with indent
Crescent moon sword, the front end cranked arm are equipped with knife-edge sword, and the crescent moon sword and the knife-edge sword are mutually twisted.
It is in place of the deficiencies in the prior art, the sharpness of tissue shear directly influences shear effect and the operation of tissue
Speed.Existing curved formula tissue shear after a number of uses its blade all can rust, be unfavorable for shearing after rust, therefore all can will be entire
Curved formula tissue shear abandons, and at this time the curved formula tissue shear cut arm, operation handle and connecting shaft can also normal use, if abandoned
Very big waste will be caused, energy conservation and environmental protection is also unfavorable for.
Utility model content
The purpose of the utility model is to provide a kind of curved formula tissue shears, and which solve existing curved formula tissue shears in edges dull
Afterwards, the problem of entire curved formula tissue shear being abandoned, causes larger waste.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of curved formula tissue shear, including arm, connecting shaft and cambered blade are cut, the arm of cutting sets there are two and passes through connecting shaft
Hingedly, the cambered blade be fixed on it is described cut arm front end, the cambered blade cuts arm one end and is provided with inserted block close to described,
Cutting is fixed on the inserted block, the cutting and the cambered blade are located at the opposite sides of the inserted block, described to insert
Item laterally offers limit hole, and the limit hole runs through the cutting two sides；

Straight line is arranged and is not put the first edge on a knife or a pair of scissors side with cambered blade 4 as ipsilateral setting.
Referring to Fig. 2,3,4,5,6,7,8,1 front end of arm is cut equipped with the fixed mechanism 13 for fixing cambered blade 4, fixed machine
Structure 13 includes cavity 131, spring 132 and inclined plane slide block 133.Cavity 131, which is located at, to be cut inside 1 front end of arm and passes through with the second slot 12
Logical, cavity 131 is located at the opposite sides of the second slot 12 with removal hole 11, and 131 end of cavity is fixed in 132 one end of spring
Portion, the other end are connect with inclined plane slide block 133.133 two sides of inclined plane slide block offer sliding slot 136, and the inner wall two sides of cavity 131 are equipped with
Guide rail 135, guide rail 135 are arranged along the width direction for cutting 1 front end of arm, and guide rail 135 slides setting in sliding slot 136 and with it.
Inclined plane slide block 133 is right-angled trapezium shape, and the inclined-plane of inclined plane slide block 133 is towards the second slot 12, the inclined-plane edge of inclined plane slide block 133
Direction far from the first slot 10 tilts down, and inclined-plane and 6 rake 8 of cutting of inclined plane slide block 133 are slidably matched, and inclined-plane is sliding
The inclined-plane of block 133 and the inclined-plane of rake 8 are set in parallel, and inclined plane slide block 133 is adapted with the limit hole 7 in cutting 6.Inclined-plane
Offer locating slot 134 on the inclined-plane of sliding block 133, locating slot 134 is close to the first slot 10, locating slot 134 and removal hole 11
Central axis be located along the same line, and locating slot 134 is identical as 11 diameter of removal hole.
Installation process: being directed at the second slot 12 for cutting 6 and be inserted into, so that the rake 8 of cutting 6 and inclined plane slide block 133
Contact of incline plane and opposite sliding, since 131 end of cavity is fixed in 132 one end of spring, the other end is connect with inclined plane slide block 133,
Therefore cutting 6 is opposite with the contact of incline plane of inclined plane slide block 133 when sliding, inclined plane slide block 133 will leave the second slot 12 and along
Guide rail 135 slides in cavity 131, and spring 132 is in compressive state at this time, after cutting 6 is completely inserted into the second slot 12, bullet
Spring 132 automatically resets, thus push inclined plane slide block 133, pass through limit hole 7 and contacted with 12 inner wall of the second slot, so that
Cutting 6 is firmly fixed in the second slot 12, and inserted block 5 is fixed in the first slot 10, to by cambered blade 4 and cut arm 1
It is connected and fixed.
Disassembly process: need to be by extraneous withdrawing device 14, extraneous withdrawing device 14 when dismantling cambered blade 4 referring to Fig. 9
For any article with aciculiform cylinder, such as toothpick, mobile phone card taking device, clip, by extraneous withdrawing device 14 from removal hole 11
Insertion, contacts it with 134 bottom of locating slot on inclined plane slide block 133, extraneous withdrawing device 14 is pushed, so that inclined plane slide block
133 leave the second slot 12 and slide in cavity 131 along guide rail 135, and spring 132 is in compressive state at this time.Inclined plane slide block
After 133 leave the second slot 12, then by the extraction outward of cambered blade 4, since extraneous withdrawing device 14 runs through limit hole 7 at this time,
Therefore cambered blade 4 can only extract a part, take out when 7 bottom of limit hole is contacted with extraneous withdrawing device 14, then by the external world
Device 14 is gently extracted, while cambered blade 4 being extracted completely outward, and cambered blade 4 at this time is kept completely separate with arm 1 is cut.Arc
After shape blade 4 is extracted, spring 132 automatically resets, to push inclined plane slide block 133, contacts it with 12 inner wall of the second slot.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
