Detailed description of the invention
Fig. 1 shows, and the present invention includes wide-mouth drill bit 1 and marrow inner sleeve nail 2.
Fig. 1 shows, and wide-mouth drill bit 1 is cylinder, and the cylindrical front end face of wide-mouth drill bit 1 has endoporus 3, and the degree of depth of endoporus 3 and diameter match with hip prosthesis 11 bottom respectively.Cylindrical being evenly distributed in of wide-mouth drill bit 1 bores tooth 4.The rear end of wide-mouth drill bit 1 is connected with drillstock 12 front end of soft brill.
Fig. 1 shows, and marrow inner sleeve nail 2 is long intramedullary pin, and the front end face of marrow inner sleeve nail 2 has taper trepanning 5, and the degree of depth of taper trepanning 5 and diameter match with the belled position of hip prosthesis 11 bottom respectively, and the rear end of marrow inner sleeve nail 5 is to curving.
Fig. 1 shows, the rivet nut of marrow inner sleeve nail 2 there is multiple horizontal lock hole 6, multiple lock hole 6 is evenly distributed along the length direction of marrow inner sleeve nail 2, lock hole 6 follows closely the through hole of 2 rivet nuts for passing perpendicularly through marrow inner sleeve, the hole wall of lock hole 6 has screw thread, and lock screw 8 matches with the screw thread of lock hole 6.
Fig. 1,2 displays, the front end taper trepanning 5 of marrow inner sleeve nail 2 has two kinds of structures, a kind of structure is the hole wall of taper trepanning 5 is complete annular, another kind of structure is that the annular hole wall both sides of taper trepanning 5 have corresponding elasticity gap 7, elasticity gap 7 is parallel with the length direction that marrow inner sleeve follows closely 2, and the length of the length of elasticity gap 7 and the belled position of hip prosthesis 11 matches.The taper trepanning 5 of the second structure inserts taper trepanning 5 during in the lower end of prosthese 11, elasticity gap 7 can open, and utilizes the elastic force of elasticity gap 7 to clamp prosthese 11 better, makes connection close and firm more.
Fig. 1,2 displays, marrow inner sleeve nail 2 is connected to form by multiple cylinder striping order, and there is cone-shaped groove the upper end of each segmentation, and the lower end of each segmentation is cone, the cone of segmentation lower end, top mates with the cone-shaped groove of segmentation upper end, below and is connected, and each segmentation has a lock hole 6.Marrow inner sleeve nail 2 adopts segmental structure to be more convenient for placing in pulp cavity.
Fig. 1,2 displays, have location gap 14 and positioning convex 15 respectively at the upper end-face edge of each segmentation and lower edge, and location gap 14 and positioning convex 15 grafting of segmentation lower end, top of segmentation upper end, below, make the location positioning of each segmentation.The distance of the lock hole 6 Distance positioning gap 14 of each segmentation is equal.So that lock hole 6 position after each connection segment point-blank.
The work process of the present invention of Fig. 3,4 displays is as follows:
By traction closed reduction prosthese 11 surrounding fracture, percutaneous slit outside femur 9 condyle, drives marrow device with tip and opens femoral bone cavitas medullaris, expands marrow with soft brill 13 in pulp cavity.
Wide-mouth drill bit 1 expands and slowly expands marrow afterwards to prosthesis handle tip, prosthesis handle tip is inserted in wide-mouth drill bit 1 central bore 3, carefully grinds, and makes to occur space around prosthesis handle tip, is finally ground to 3CM place above prosthesis handle tip.Take out wide-mouth drill bit 1 and drillstock 12.
Implant marrow inner sleeve nail 2, inserted by each striping order, the cone-shaped groove of each segmentation is connected relatively with cone, and location gap 14 and the positioning convex 15 of adjacent sectional plug.After marrow inner sleeve follows closely 2 near-ends and prosthesis handle nib contacts, make prosthesis handle tip insert marrow inner sleeve and follow closely in the taper trepanning 5 of 2 near-ends, knock marrow inner sleeve with hammer and follow closely 2 far-ends, make it closely to be socketed with prosthesis handle.Perspective lower application lock screw 8 fixes marrow inner sleeve nail 2, and requiring marrow inner sleeve to follow closely in the lock hole 6 of 2 has screw thread, make lock screw 8 and marrow inner sleeve follow closely 2 between combine tightr.
