Description
Technical field
This utility model relates to medical apparatus and instruments field, particularly relates to a kind of scalpel, especially relates to a kind of super
Sound osteotome cutter head.
Background technology
In modern society, along with the development of medical skill, bone surgery presents diversified trend, correspondingly, implements hands
During art, it is required for the different orthopaedics state of an illness and uses difform knife head for surgical that affected part is cut, grinding, scrape treatments, press from both sides
The operation such as hold.
For the special tectonic of skeletal structure, in conjunction with the ultrasonic technique of development in recent years, piezosurgery osteotomy is increasingly becoming
The main tool of modern bone surgery.Piezosurgery osteotomy is to utilize high intensity focused ultrasound technology, by transducer, converts electrical energy into
For mechanical energy, shake through high frequency ultrasound, make moisture vaporization in contacted histiocyte, albumen hydrogen bond rupture, thus will perform the operation
The middle osseous tissue needing cutting thoroughly destroys.Owing to this high-intensity focusing ultrasonic wave only has destruction to the osseous tissue of particular stiffness
Effect, has to cut and does not firmly cut soft characteristic, thus being particularly well-suited to peripheral is skeletal structure, and centre is this parenchima of spinal cord
Spinal operation.Utilizing piezosurgery osteotomy to carry out operation and can be effectively prevented owing to overexerting in operation, imprudence hurts ridge
The generation of the malpractice of marrow, thus improve operation safety.
In bone surgery, the sheet shape cutter head of commonly used piezosurgery osteotomy is a kind of to be cut into main cutter head, but
Mostly current this kind of cutter head is based on straight plate shape, and its blade direction is identical with ultrasonic osteotome bit axis direction.Its cutting track
Can only carry out along ultrasonic osteotome bit axis direction, vertically cut and there is good cutting effect.But concrete operation feelings
Condition varies, and needs the operation technique of transverse cuts for some, and owing to operation technique space is limited, this for rip cutting
Raw straight plate shape cutter just loses ample scope for abilities.

Knife bar, two blades that cutting part includes laying respectively at cutting part both sides and upper edge that is vertical with blade and that be oppositely arranged
With the axis that lower tangent plane, upper edge and lower tangent plane favour ultrasonic osteotome bit.
When using ultrasonic osteotome bit of the present utility model to carry out particular procedure, owing to the bending of ultrasonic osteotome bit is tied
Structure, it is possible to help doctor to walk around spinal cord and carry out horizontal cutting osteotomy operation, it is also possible to complete the horizontal stroke to some invisible area
Operate to osteotomy；When working place is less, ultrasonic osteotome bit of the present utility model can replace straight plate shape to complete osteotomy behaviour
Make, thus reduce the incision length of operation, reduce operation risk, shorten operating time.
Preferably, the upper edge of cutting part and knife bar use arc transition, and form imploded arcs at transition position；Cutting part
Lower tangent plane uses arc transition with knife bar, and forms outer convex arc at transition position.Arc structure is the conventional design hands of Machine Design
Section, uses arc transition on the one hand stress can be avoided to concentrate, on the one hand can be so that processing, it is even more important that permissible
Effectively prevent the injury to body tissue of the sharp-pointed corner of wedge angle transition.
Preferably, cutting part is the flat chip architecture that upper edge is parallel with lower tangent plane.Cutting part is flat chip architecture, spatially
The position taken is less, it is possible to room of manoeuvre is bigger, has broader practice scope.
Preferably, cutting part be by cutting part rear end along upper edge and lower tangent plane bus gradually forward end draw in gradual change
Flat chip architecture.Operator can need to select difform ultrasonic osteotome bit according to difference, preferably completes operation.
Preferably, lower tangent plane is provided with reinforcement, and blade protrudes from the outer surface of reinforcement.Reinforcement is propping up of cutting part
Support structure, it can be effectively improved the service life of ultrasonic osteotome bit, meanwhile, be convex owing to completing the part of cutting
For the blade of reinforcement, therefore, reinforcement does not interferes with the cutting effect of ultrasonic osteotome bit.
Preferably, a blade in two blades offers cutter tooth；Preferably, two blades offer cutter respectively
Tooth.The setting of cutter tooth makes medical personnel preferably hold facet when cutting, and quickly completes cutting.
Preferably, cutting part termination is arc structure or planar structure, can be effectively prevented wedge angle to body tissue
Injury.
Preferably, the tail end at knife bar offers screw thread.Ultrasonic osteotome bit is close-coupled at by being provided for of screw thread
On piezosurgery osteotomy transducer.
Compared with prior art, the advantage of this utility model embodiment is: the ultrasonic osteotome bit in this utility model
