Description
Technical field
The invention belongs to technical field of medical instruments, especially relate to and a kind of multiplexly get bone device.
Background technology
In bone surgery process, sometimes need to get spongy bone on the ilium of patient, for the transplanting of bone, existing bone object of getting generally comprises and gets bone urceolus, cutting is provided with at the forward end getting bone urceolus, when bone urceolus is got in rotation, bone cuts and makes it be cylinder by the cutting of its front end, and the spongy bone after incision is contained in be got in the appearance bone cavity of bone urceolus.The existing practice is, direct bone object of getting takes out from ilium, under normal conditions, get the cylindrical cancellous influential point of bone in bone urceolus and ilium main part disconnects, after getting bone urceolus and taking out, the cylindrical cancellous influential point of bone taken out is kept to be got in bone urceolus, then is used for transplanting from getting in bone urceolus spongy bone to take out.But in some cases, the spongy bone got in bone urceolus does not disconnect with ilium main part, when bone urceolus is got in taking-up, gets spongy bone in bone urceolus from getting in bone urceolus, and stay ilium main part, not easily disposable taking-up, the effect of bone is got in impact, even sometimes needs again to operate and gets bone, not only extend operating time, also increase the wound to patient, if it is unsuccessful repeatedly to get bone, adverse effect can be caused to patient.In addition, existingly get getting when bone urceolus has just started sawing of bone object and easily produce skidding, easily like this cause scuffing to ilium surface, what be unfavorable for performing the operation normally carries out.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses one and gets bone object [application number: 201320842231.8], comprises and gets bone sleeve, a T-handle and cross bar, and this T-handle end is provided with blade; Getting bone sleeve one end is zigzag, and one end is provided with opening; In the one end of getting bone sleeve and be provided with opening, the direction perpendicular to sleeve axis is provided with a cross bar passage, getting before in bone sleeve insertosome, is inserted into by cross bar in this cross bar passage; Rotating this cross bar makes to get after bone sleeve enters sclerotin Inner, extracts cross bar out, the T-handle with blade is reached the inside of getting bone sleeve from getting bone sleeve openings, and rotating blade is for the connection cut off between the sclerotin getting and take out in bone sleeve.Such scheme to some extent solves existing problem of getting bone weak effect, but the program still also exists: cannot position getting bone object, easily scratches the problem on ilium surface.
Summary of the invention
The object of the invention is for the problems referred to above, provide a kind of reasonable in design, bone incision can be completed and get bone device with the multiplex of taking-up.
For achieving the above object, present invention employs following technical proposal: basis is multiplex gets bone device, it is characterized in that, this device comprises cylindrical body, locating rod and get bone shovel body, the end of described cylindrical body front end is provided with the sawtooth body of some circumference distributions, described cylindrical body rear end is provided with the twist mechanism that cylindrical body can be driven to rotate, described cylindrical body has axially through and can insert locating rod respectively and get the central passage that bone shovels body, described locating rod front end has the locating cone point being exposed to cylindrical body front end when locating rod inserts in central passage, described locating rod rear end has the forced section for bearing applied external force, described bone shovel body of getting comprises the body of rod and is arranged on lever front end and has the shovel head storing up osseous part.During use, first by locating rod is inserted in central passage, and make locating cone spike enter bone surface to forced section applying pressure, then rotating cylindrical body by twist mechanism makes sawtooth body start sawing bone, such sawtooth body not easily skids when starting sawing, not easily damaged bone head surface, after cylindrical body completes sawing, locating rod is extracted out, then will get bone shovel body inserts in cylindrical body, by shovel head, the spongy bone in cylindrical body and ilium main part are disconnected, and by storage osseous part, the spongy bone of separator well is taken out, realize not needing to extract cylindrical body out to realize repeatedly getting bone.
