Description
Technical field
The present invention relates to area of medical devices.
Background technique
Osteotome is common surgical medical tool in the long clinical practice of orthopaedics, and the osteotome clinically used at present is usually one
The design of body formula, digs body and chisel head is integrally formed, and cuts bone tissue using chisel head during use.
Since there is certain deviation in the position of bone tissue, effect can be more preferable if osteotome is bending.And existing osteotome
Mainly unitary design, and the type that is mainly in line, it is inconvenient to use in some cases.
In some cases, chisel head has been designed to bending, is conducive in this way using but this curved chisel head is not
Perpendicular to the position of bone tissue, using effect is limited, sometimes up to less than the effect of anticipation.
Existing osteotome is all integral type simultaneously, and chisel head is easily damaged, but wants integral replacing, is not saved, and is needed frequently
The osteotome that use different model, can only replace entire osteotome.
Summary of the invention
It is an object of the invention to: in view of the above problems, provide a kind of osteotome, include chisel bar and with chisel bar
The chisel head of connection, the chisel bar include the first chisel bar and the second chisel bar, and the first chisel bar and second dig the bent connection of bar, the
One, which digs bar and second, digs the connecting pin of bar as hollow pivoted housing, and the second chisel bar is equipped with the core of the deep enough pivoted housing of energy, pivoted housing wall
Be equipped with recess portion, core wall, which is equipped with, can be caught in the protrusion of recess portion, and core is fixedly connected with spacing head, spacing head and pivoted housing it
Between be equipped with spring, to limit core far from pivoted housing, and both fixed axial position, the outer layer of core is equipped with half rotary sleeve, half
Rotary sleeve is equipped with outs open, and core is fixed on the bottom of half rotary sleeve, and half rotary sleeve is connected with the second chisel bar, the second chisel bar and
First chisel bar axial direction is identical.
Pivoted housing of the present invention is connected with the first chisel bar, and core is connected with the second chisel bar, and core of the invention and pivoted housing can edges
Axial rotation be respectively equipped on core and pivoted housing mutually with driving capable of mutually bending for the first chisel bar and the second chisel bar
The protrusion of cooperation and recess portion are to fix the angle of bending.Simultaneously be equipped with spacing head connect with core, and be equipped with spacing head with
Between pivoted housing be equipped with spring the position of protrusion and recess portion to be fixed, prevent protrusion from removing from recess portion, at the same can guarantee from
Protrusion can be removed from recess portion under external force.When needing to change the first chisel bar and the second chisel bar angle, for that will turn
Core, to remove protrusion from recess portion, rotates core from a part is extracted in pivoted housing, then the first chisel bar and the second chisel bar angle turn
It is dynamic, until going to the proper angle of needs, and ensure that protrusion is corresponding with some recess portion, is firmly used for release force, makes its active
Or passively stick into recess portion and fix, then the angle of the first chisel bar and the second chisel bar is changed, and is suitble to the tool of osteotome
Body needs.
Guaranteeing that the first chisel bar and the second chisel bar are axial in the case where a straight line, this when of power is easy transmitting,
The present invention is being equipped with rotation nested structure.
The recess portion is multiple greater than 1, and quantity is more, and the precision of adjustment is bigger, in one embodiment,
The quantity of recess portion is 5.
And the quantity of the protrusion is greater than 1 quantity for being less than or equal to recess portion, such as 1 recess portion of protrusion 5 or 2
The recess portion of a protrusion 5, but to ensure that protrusion can stick into recess portion, that is, adjacent projection distance be equal to adjacent recesses away from
From.
Because to be undertaken at the cooperation of recess portion and protrusion the first chisel bar and second chisel bar folding force, multiple protrusions and
The design of recess portion can disperse this folding force, on the one hand increase service life, on the other hand it is also possible that its stability is high.
Preferably, the spacing head and core are threadedly coupled, so that easy to disassemble.
Preferably, the pivoted housing is equipped with the cavity of a placement spring section.
In the present invention, osteotome will bear biggish impact force, especially when osteotome is bent, rigidity and surrender
It is most important whether intensity meets condition.Therefore in the scheme improved to existing osteotome material.The osteotome is by copper-based
Composite material is made, the Cu-base composites include 100 parts of cathode copper, 0.1-2 parts of zinc, 0.1-2 parts of cobalt, 0.1-2 parts of nickel,
0.1-1 parts of gallium, 1-5 parts of silicon, 0.01-0.1 parts of lanthanum, composite material are formed by vacuum fusion.
As an improvement, cathode copper uses 99.99% high-purity electrolytic copper.
As an improvement, copper-based alloy material includes 2 parts of zinc, 2 parts of cobalt, 2 parts of nickel, 1 part of gallium, 5 parts of silicon, 0.1 part of lanthanum.
When above-mentioned material, osteotome have biggish rigidity and yield strength, bending strength reach 1300Mpa with
On, hardness reaches 400HV or more.When especially bending, biggish impact force, long service life can be received.
