Abstract
The present invention relates to a hollow soft drill and its production method. In particular, it relates to a hollow soft drill for taking out prosthesis holder from marrow cavity and its making method. Said hollow soft drill is formed from drillstock, hollow cover and cutting edge. Besides, said invention also provides the concrete steps of its making method.
Description
Technical field:
The present invention relates to a kind of hollow soft drill and preparation method thereof, especially hollow soft drill that taking-up prosthese handle is used from pulp cavity and preparation method thereof.
Technical background:
In the medical operating, in femur, take out foreign body such as broken nail and adopt hollow bone drill often, as: the hollow bone drill that CN86203850, ZL97213490.5 are related, such hollow bone drill partly is made up of drillstock, hollow sleeve and cutting edge three, and drillstock, hollow sleeve and cutting edge are with one heart and are rigidity.In medical operating, when due to illness patient becomes when needing in pulp cavity artificial prosthesis to be installed, in order to guarantee the prosthese mounting stability, having packed in pulp cavity has the prosthese handle of identical radian measure with the bone pulp cavity, and pours into mechanical performance and the approaching bone cement of ABS plastic between pulp cavity and prosthese handle.Because prosthese ruptures sometimes, if need the prosthese handle to be taken out in the pulp cavity and new prosthese is installed, the hollow bone drill that then adopts above-mentioned rigidity obviously is inappropriate.
Summary of the invention:
The purpose of this invention is to provide a kind of hollow soft drill and preparation method thereof, prosthese handle and bone cement are taken out in pulp cavity to adapt to.
Hollow soft drill of the present invention is by drillstock, hollow sleeve and cutting edge are formed, drillstock is connected with the hollow sleeve upper end by pin, cutting edge and hollow sleeve lower end fuse, it is characterized in that: hollow sleeve is made up of some groups of chain links, two horizontal weak points are continuous up and down by two for every group of chain link, the centre is grown and is linked to each other just as the composition of " king " word, last group of chain link is mutually 90 degree with following group chain link, make following two horizontal embeddings of group chain link organize the space between two horizontal strokes on the chain link down, in the formation, under organize chain link and interconnect, be provided with convex shoulder in next horizontal stroke of each " king " word, per two " king " words middle are horizontally set with fluted, convex shoulder embeds in the groove, in case on, under organize between the chain link laterally and throw off.
Hollow soft drill manufacture method of the present invention is: the rigidity hollow sleeve of making a band cutting edge at first according to a conventional method, it is characterized in that: make heat treatment after each makes a call to a fabrication hole at place in the middle of the top of each " king " word of the every group of chain link in the face of cylinder of hollow sleeve and the bottom, again drillstock and hollow sleeve are fused by pin, with the cylindrical of hollow sleeve and drillstock each other benchmark process, make and have good axiality between the two, line cutting silk is penetrated in the fabrication hole at two " king " word crown center places in the chain link on the same group, line cutting silk along the last traverse rod mark of these two " king " words cut to organize in the chain link two next traverse rod marks of " king " word after, hollow sleeve is rotated 90 degree, again line cutting silk is penetrated in the fabrication hole of organizing middle place, two " king " word bottoms in the chain link on this, track cutting along its convex shoulder, after two cutting tracks intersect, hollow sleeve is cut off again, in the formation, following two groups of chain links interconnect, and the like get final product.
Hollow soft drill of the present invention because its hollow sleeve has adopted said structure, makes hollow sleeve can curve certain radian, can satisfy the slightly drilling of crooked radian.Use the problem of taking out prosthese handle and bone cement in the pulp cavity that solved through clinical practice.Hollow soft drill manufacture method of the present invention, each makes a call to a fabrication hole at the middle place, two " king " word tops and bottoms of the every group of chain link in the face of cylinder of hollow straight sleeve owing to adopt, reuse line cutting processing, make the processing of hollow soft drill very simple and effective, also provide a kind of easy processing method for making similar soft brill.
Description of drawings:
Fig. 1, structure chart of the present invention;
The local expanded view of Fig. 2, hollow core of the present invention cover.
The specific embodiment:
By shown in Figure 1, the present invention is made up of drillstock 1, hollow sleeve 4 and cutting edge 2, and drillstock 1 is connected with hollow sleeve 4 upper ends by pin 3, and cutting edge 2 fuses with hollow sleeve 4 lower ends, and hollow sleeve 4 is made up of some groups of chain links 5.
By shown in Figure 2, hollow sleeve is made up of some groups of chain links, two horizontal weak points are continuous up and down by two for every group of chain link, the centre is grown and is linked to each other just as the joint composition of " king " word, last group of chain link 6 is mutually 90 degree with following group chain link 7, make next horizontal embedding of group chain link 6 organize the space between two horizontal strokes on the chain link 7 down, form upper and lower group of chain link 6,7 and interconnect.Be provided with convex shoulder 10 in next horizontal stroke of each " king " word, one is horizontally set with flutedly 11 in the middle of per two " king " words, and convex shoulder 10 embeds in the grooves 11, in case between upper and lower group of chain link 6,7 along laterally relatively moving and throwing off.The wire cutting method of hollow sleeve is: in the middle of the top of every group of chain link " king " word and bottom the place each make a call to a fabrication hole 8,9, line cutting silk is penetrated down in the top fabrication hole 8 of 7 two " king " words of group chain link, after a line cutting last traverse rod mark along these two " king " words cuts to next traverse rod mark of two " king " words in the group chain link, hollow sleeve is rotated 90 degree, again line cutting silk is penetrated in the fabrication hole 9 of organizing two " king " word bottoms in the chain link 6 on this, track cutting along its convex shoulder, after two cutting tracks intersect, hollow sleeve is cut off, in the formation, under organize chain link 6,7 interconnect, and the like get final product.
