The invention effect
Medical cutting element of the present invention, has formation as above, thereby be covered with the open-ended a plurality of cutting blades of radial formation that are of tubular body section, with the continuous setting of the core of a plurality of cutting blades, the central tip section that formation is outstanding along central shaft to foreign side, therefore, if centered by central shaft rotating main body section, the a plurality of cutting blade parts that are the radiated entends setting just rotate centered by central tip section, can carry out the stable stock removal action towards central axis direction.
In addition, between a plurality of cutting blades, form a plurality of importing oral areas that cutting object imported tubulose main part inside, therefore accommodated in main part inside by the cutting object former state of cutting blade cutting.Thereby the cutting object that is accumulated in main part inside after stock removal action can being finished reclaims and recycles, and cutting object can be able to not flowed out ground and really reclaim.
In addition, the cutting blade forms to central shaft to outstanding periphery point at its outer circumferential side, thus can be in the stock removal action process direction center point and periphery point, carry out more stable stock removal action.And, because central part and peripheral part cut highlightedly, the shape of the approximate implant in the bottom surface of the hole section of boring a hole along with stock removal action thus, if cut until central tip section reaches prescribed depth, the degree of depth of implant of can pegging graft of just can boring a hole.Thereby, need not cut too much the live body bone, can suppress the damage to the live body bone.In addition, owing to can be finish-machined to the hole section of approximate implant shape, the implant of therefore pegging graft and the gap smaller between the section of hole can be accelerated bone to implant regeneration on every side.
In addition, the cutting blade is to intersect and form blade tip along a side of central shaft and with respect to the another side of inclined, even therefore also can keep enough intensity when covering open-ended formation cutting blade.And, the part that the another side of one side of 1 cutting blade and the cutting blade that is adjacent intersects forms the paddy shape, partly form the importing oral area at its paddy shape, therefore make the cutting object of the live body bone that cuts at blade tip import to swimmingly the importing oral area along with the rotation of main part, can positively carry out the recovery of cutting object with the spinning movement of main body action with being consistent.
In addition, the taking-up member that will take out from importing cutting object that oral area imports is housed in tubular body section inside, the cutting object that thus can efficient will be accumulated in along with stock removal action well main part inside takes out.
The collection kit that cuts bone of the present invention, has formation as above, thereby comprise that tubulose inserts member, it is the shape that has in the cut-out trace that can insert the bone parting tool, supporting member, it is to supporting removably the insertion member along central shaft, be arranged on simultaneously and insert component inside extends setting along central shaft bar-shaped screw thread fixed part, if therefore one side is inserted member toward the tubular bone parting tool that adopts leading section to form sawtooth in the cut-out trace that the live body bone forms, a rotating support member, then the internal whorl fixed part screws in the live body bone, if extract supporting member at the state that screws in the screw thread fixed part, just can collect the whole former state of the bone of cut-out.And, owing to being simultaneously will insert in the member insertion cut-out trace simultaneously to screw in the screw thread fixed part, therefore the screw thread fixed part can not deviate from from the bone of cut-out, can positively screw in the inside bone into cut-out, fore-end bone at the screw thread fixed part when extracting supporting member separates, collect, thereby can reliably collect the bone integral body of cut-out to the drains.
Thereby after bone was collected, the spliced eye of the implant that forms on the bone can be worked into the degree of depth when cutting off neatly.In addition, from supporting member along central shaft to the insertion member of dismantling, the bone integral body that makes the screw thread fixed part screw in inner cut-out is exposed, if from the bone of the cut-out screw thread fixed part of dismantling, do not flow out to the outside when the bone after then collecting can be as pulverizing, can obtain simply cut-out bone.In addition, the bone of collection can not pulverized like this, and keeps the former state state of live body bone to collect, and therefore can obtain with the former state state tissue of bone surface and inside etc., can be according to the position separate processes of bone yet.
In addition, screw togather and install as long as will insert member and supporting member, just can be along central shaft to installing simply removably, in addition, when one side rotating support member simultaneously operates, also can not make and insert member and carry out stable operation with deviating from.
In addition, as long as set the front end of screw thread fixed part than the inner side of opening who inserts member, just can under the state in the cut-out trace of the opening insertion bone parting tool that inserts member the front end of spiral fixed part be contacted with bone, can insert rotating support member under the state of insertion of member in the screw-in position of more positively setting screw thread fixed part front end by the insertion of inserting member and direction, can screw in fixed part with the steady statue that can not break away from from the bone of cut-out.
In addition, as long as the screw thread fixed part is formed taper, so that become the shape of its front end point, just can screw in swimmingly inside bone, also can not destroy bone ground when from bone, pulling down the screw thread fixed part and easily pull down.
The ways of medical cutting element of the present invention, has aforesaid formation, its setting of the width of slit slot part is narrower and wider than cutting the width that this outer peripheral face part is the insertion section that forms in a narrow margin than medical cutting element outer peripheral face external diameter, thereby can easily medical cutting element be plugged into guide part, also can operating stably when the rotary hospital cutting element is bored a hole action simultaneously.
Namely, when medical cutting element is plugged into guide part, if the insertion section of medical cutting element is laterally inserted corresponding to the slit slot part, then because the width setup of the Width insertion section of slit slot part gets wide, therefore can make the insertion section simply by the slit slot part, can easily medical cutting element be installed to guide part.
In addition, when using cutting element to be plugged into state rotary hospital in the guide part, because the width setup of slit slot part must be narrower than the external diameter of the outer peripheral face of medical cutting element, thereby prevented that really medical cutting element is from guide part flies out the slit groove in spinning movement.Thereby medical cutting element rotates in guide part with stable state, medical cutting element can be directed on the predefined cutting direction.
In addition, as guide part, be that the cylindrical structural member that will have the slit corresponding with the slit slot part is fixed on the main part and uses, thus, can adopt the material that spinning movement is smooth, mar proof is high at cylindrical structural member, to allow to be rotated swimmingly action.And, as long as be shaped exactly in advance processing and being fixed on the main part of cylindrical structural member, just can improve the precision of guide part inner peripheral surface, can set accurately the cutting direction of medical cutting element.
In addition, when making ways, as long as the cylindrical structural member of preshaped processing is fixed, form guide part and get final product, the situation that forms guide part with direct processing main part is compared, easily the high ways of the accuracy of manufacture.
