Abstract
The present invention relates to a kind of mark scraper for thigh bone far end, for drawing the scoring tool of logical condyle line after distal femur osteotomy in replacement knee in arthroplasty, mark scraper for thigh bone far end includes fixing end, movable end, locating dowel, marking groove, fixing end is with movable end lower surface in one plane, and fit with the distal femur after osteotomy of distal, cave in inside projection and condylus medialis femoris outside condylus lateralis femoris after locating dowel and osteotomy of distal and fit, the logical condyle line marked by marking groove is that femur osteotomy provides reference, reduces the dependence to whole femur preartis or postartis。
Description
Technical field
The present invention relates to replacement knee in arthroplasty instrument, particularly to a kind of mark scraper for thigh bone far end。
Background technology
Continuous progress along with medical skill, artificial knee replacement surgery has been increasingly becoming a kind of relatively common surgical operation, femur side common practice is using complete femur preartis or postartis as with reference to row osteotomy after distal femur osteotomy, but often occur that patient's femur preartis or postartis have worn out, pathological changes, or art occurs the destruction to preartis or postartis, thus cannot function as osteotomy reference, now it is usually and relies on the experience of doctor to judge osteotomy site, cause the prolongation of operating time, raising to the dependence of doctors experience and operative failure rate。
Summary of the invention
It is an object of the invention to femur preartis and postartis in replacement knee in arthroplasty and cannot function as under osteotomy reference case, it is provided that the scoring tool of osteotomy reference。
For achieving the above object, the present invention takes following design:
A kind of mark scraper for thigh bone far end, for drawing the scoring tool of logical condyle line after distal femur osteotomy in replacement knee in arthroplasty, it is characterized in that, mark scraper for thigh bone far end includes fixing end, movable end, locating dowel, marking groove, together with fixing end is interspersed in described movable end, other motion modes except axially-movable are limited, and marking groove is a part for movable end。
Described mark scraper for thigh bone far end fixes the lower surface of the lower surface of end and movable end in one plane, and the distal femur after above-mentioned lower surface and osteotomy of distal fits。
The locating dowel diameter of described mark scraper for thigh bone far end is 3mm, has two, is individually fixed in the two ends of fixing end and movable end。
Described mark scraper for thigh bone far end marking groove is wide at the top and narrow at the bottom, and narrow partial width is 3mm。
The processing method of described mark scraper for thigh bone far end is: adopt laser sintered or high-power electron beam melt molding, it would however also be possible to employ the mechanical means such as spark machined, and material can be biocompatible nylon material can also be medical metal material。
The invention have the advantage that
1. mark scraper for thigh bone far end of the present invention, for drawing the scoring tool of logical condyle line after distal femur osteotomy in replacement knee in arthroplasty, including fixing end, movable end, locating dowel, marking groove, together with fixing end is interspersed in movable end, other motion modes except axially-movable are limited, and marking groove is a part for movable end。
2. mark scraper for thigh bone far end of the present invention, with the lower surface of movable end in one plane, the distal femur behind lower surface and osteotomy of distal fits in the lower surface of fixing end。
3. mark scraper for thigh bone far end of the present invention, locating dowel diameter is 3mm, has two, is individually fixed in the two ends of fixing end and movable end, is individually fixed in outside condylus lateralis femoris recess inside prominence and condylus medialis femoris。
4. mark scraper for thigh bone far end of the present invention, marking groove is wide at the top and narrow at the bottom, and narrow partial width is 3mm, can guarantee that the accuracy passing through and ensureing drawn straight line of pen。
5. mark scraper for thigh bone far end of the present invention, processing method is: adopt laser sintered or high-power electron beam melt molding, it would however also be possible to employ the mechanical means such as spark machined, and material can be biocompatible nylon material can also be medical metal material。

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the invention is described in further details。
Such as Fig. 1, shown in Fig. 2, mark scraper for thigh bone far end of the present invention, for drawing the scoring tool of logical condyle line after distal femur osteotomy in replacement knee in arthroplasty, mark scraper for thigh bone far end includes fixing end (1), movable end (2), locating dowel (3), marking groove (4), together with fixing end (1) is interspersed in movable end (2), other motion modes except axially-movable are limited, locating dowel (3) has two, it is individually fixed in the two ends of fixing end (1) and movable end (2), it is individually fixed in the both sides of condyle of femur, marking groove (4) is a part for movable end (2)。
As shown in Figure 4, adopt the mark scraper for thigh bone far end of the present invention, after distal femur osteotomy, fixing end (1) locating dowel (3) is fixed on projection outside condylus lateralis femoris (8) place, movable end (2) locating dowel (3) is fixed on depression (9) place inside condylus medialis femoris, and the lower surface of fixing end (1) and movable end (2) and distal femur osteotomy surface (7) are fitted, then use marking pen for medical use to rule along marking groove (4)。
Locating dowel (3) diameter of the fixing end (1) of the present invention and movable end (2) only has 3mm, it is possible to the accuracy positioned with ensure to cave in inside projection (8) and condylus medialis femoris outside condylus lateralis femoris (9)。
The lower surface of the fixing end (1) of the present invention and movable end (2) is in one plane, it is possible to guarantee scriber fits tightly with distal femur osteotomy surface (7)。
Marking groove of the present invention (4) is wide at the top and narrow at the bottom, it is possible to meeting the use of medical bow pen, marking groove (4) lower end width only has 3mm, it is possible to ensure the uniqueness of drawn straight line。
Mark scraper for thigh bone far end of the present invention, biocompatibility nylon material or medical metal material is adopted to make, therefore there is good biocompatibility, the processing method of described mark scraper for thigh bone far end is: adopt laser sintered or high-power electron beam melt molding, it would however also be possible to employ the mechanical means such as spark machined。
Embodiment of above is merely to illustrate the present invention, and is not intended as the restriction of the present invention。Those of ordinary skill about technical field, without departing from the spirit and scope of the present invention, it is also possible to make a variety of changes and modification, therefore, all changes that it will be apparent to those skilled in the art that, are intended to be included within the scope that present claims book is contained。Present invention scope required for protection is only defined by described claims。
