Including the end cover of osteotome sword, osteotome handle, osteotome handle afterbody, its characterized in that: the osteotome sword comprises sword portion and installation department, and the installation department of osteotome sword becomes the cylinder that axial direction was equipped with plane A, or the installation department of osteotome sword becomes the polyhedron, and the axial direction that installation department that the osteotome handle was equipped with the osteotome sword can correspond insert the installation is equipped with plane B's cylinder jack, or the osteotome handle installation department that is equipped with the osteotome sword can correspond insert the installation's polyhedron jack, the osteotome handle still is equipped with screw and locking bolt with the fixed locking of installation department of osteotome sword. The utility model discloses can prevent that the relative osteotome handle of osteotome sword is rotatory, the position is cut to the former chisel of the skew skeleton of osteotome sword when causing in the operation the deep bone of chisel, can prolong the life of osteotome instrument, according to the needs of operation, can conveniently change the osteotome sword on the osteotome handle.
Description
Technical field
This utility model relates to medical mechanical domain, specifically during a kind of surgery bone surgery for cutting a hole the instrument of deep bone.
Background technology
Osteotome is the instrument that a kind of applying frequency is higher in bone surgery, and its method of work is that application hammer knocks its afterbody generation strength to cut a hole deep bone.On the one hand, different parts and the skeleton of shape require that osteotome knife-edge shape is different with specification, certainly will frequently change osteotome cutter.On the other hand, general osteotome handle and osteotome cutter are threaded connection, and knock lower screw thread be easily out of shape at hammer, handle is connected with osteotome cutter and easily lost efficacy.As publication number: CN10233903A " changeable type sliding hammer power osteotome (cutter) " sliding hammer and osteotome (cutter) are threaded connection, and when binding nut 4 is beaten in cylindrical shape hammer portion 5 during work, can cause two kinds of adverse effects.One is easily cause both the relative rotations of sliding hammer and osteotome (cutter); Two is that cloudy screw on sliding bar pin threads and afterbody is easily out of shape, thus causes sliding hammer and osteotome (cutter) to be difficult to dismounting or assembling.And publication number: CN10396355A " under a kind of split type mirror osteotome " embodiment one exists and publication number: CN10233903A " changeable type sliding hammer power osteotome (the cutter) " disadvantage that sliding hammer is identical with osteotome (cutter); Embodiment two when osteotome enter sclerotin comparatively dark or card pressure is tighter time extract time straight-bar 2 be easily separated with cutter head 3.
Summary of the invention
The purpose of this utility model to provide a kind of osteotome instrument being changed fixing osteotome cutter by osteotome handle socket, it can overcome the disadvantage of above-mentioned prior art, knock osteotome handle to impact the firm connection of osteotome handle, osteotome cutter, also can not cause any damage to osteotome handle, osteotome cutter; It is also configured with more than two osteotome cuttves, can meet the needs of different surgical object to osteotome cutter completely.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of osteotome instrument being changed fixing osteotome cutter by osteotome handle socket, comprise osteotome cutter, osteotome hands handle, the end cap of osteotome handle afterbody, its main points are: osteotome cutter is made up of cutter portion and installation portion, the installation portion of osteotome cutter becomes axial direction to be provided with the cylinder of plane A, or the installation portion of osteotome cutter becomes polyhedron, the installation portion that osteotome handle is provided with osteotome cutter correspondingly can insert the cylinder jack that the axial direction installed is provided with plane B, or osteotome handle is provided with the corresponding polyhedron jack inserting installation of installation portion energy of osteotome cutter, osteotome handle is also provided with the screw of the installation portion fixing and locking of osteotome cutter and clamping screw.
As preferably, the installation portion of osteotome cutter becomes axial direction to be provided with the cylinder of plane A, and the installation portion that osteotome handle is provided with osteotome cutter correspondingly can insert the cylinder jack that the axial direction installed is provided with plane B.
As preferably, clamping screw head is set as hemispherical, and the installation portion of osteotome cutter is shaped with the blind hole that clamping screw hemispherical nose can head into.
As preferably, the end cap of osteotome handle afterbody to improve its mechanical strength through Overheating Treatment, can withstand in operation and cut a hole knocking of bone hammer.
As preferably, described osteotome cutter is provided with cutter portion width 5-35 millimeter two above osteotome cutter.
This utility model, compared with existing osteotome, can prevent the relative osteotome rotatable handle of osteotome cutter, causes in operation osteotome cutter when cutting a hole deep bone to depart from the former cutter of skeleton and cuts position; Knock osteotome handle to impact the firm connection of osteotome handle, osteotome cutter, also can not cause any damage to osteotome handle, osteotome cutter, so the service life of osteotome instrument can be extended; According to the needs of operation, the osteotome cutter on osteotome handle can be changed easily; And there is rational in infrastructure, low cost of manufacture, the advantage such as easy to use.
