Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to anti-rotary knife piece Proximal femur assembly type prosthese.
Background technology
The operation of Proximal femur tumour backbone defect reconstruction is always one of clinical orthopaedics difficult point.In order to obtain reliable prosthese
Stability, the operative reconstruction scheme of existing clinical maturation is Proximal femur tumour tumor resection, in the lump cut off femoral trochanter area and
Femoral head neck region, row tumprigenicity total hip replacement or hemiarthroplasty.But this operation plan has the disadvantages that：1st, perform the operation
Wound is big, and Operative Range is wide, and the unrelated femoral trochanter area of tumor resection and neck area are needed in art；2nd, surgical disruption stock
Bone region trochanterica adheres to muscle group and capsula articularis coxae structure, and postoperative hip joint and suffering limb functional rehabilitation are slow, or even postoperative limb function one
Determine degree loss；3rd, prosthese limited lifetime, hip-joint replacement prosthesis life cycle is generally 15 years or so, with oncotherapy water
Flat to improve, survival greatly improves, and necessarily faces the prosthese second phase and overhauls, prosthese second phase revision procedure wound and operating difficulty
Greatly.
The content of the invention
The present invention is intended to provide with anti-rotary knife piece Proximal femur assembly type prosthese, operation wound is small, and operation need to only cut off swollen
Knurl invades scope, is not required to excision femoral trochanter area and femoral head neck region.

Further, there are hydroxyapatite coating layer in near-end prosthese and distal end broach outer surface.
Wherein, the length of the outer cone is 50mm.
Further, the length of the distal end broach is 80mm-120mm.
Further, the duct top rake of inserting for 10 °, do the angle formed between anti-rotary knife piece and be by near-end prosthese
130°。
It is driven into use, near-end prosthese is slotted from greater trochanter top Pyriform sinus after expanding marrow to distal femur, anti-rotary knife piece 1 is from putting
Enter duct to be driven into along neck of femur axis；Distal femur side prosthesis component, which is driven near end of thighbone prosthesis assembly, to carry out assembling connection,
And pass through limit protrusion and limiting slot padlock.
Compared with prior art, the invention has the advantages that：
1. small using operation wound of the present invention, operation only needs tumor resection to invade scope；
2. near end of thighbone lesser trochanter above structure is not destroyed, femoral trochanter area attachment muscle group and femoral head neck region are effectively protected
Structure, postoperative suffering limb function effect are smaller；
3. the present invention is bion prosthese, surface carries out painting designs, and biological reconstruction is finally reached as bone trabecula is grown into,
Prosthese failure probability is small, and it is small that the second phase overhauls probability；
4. the personalized prosthese of the present invention, can be according to patient tumors backbone defect scope, femoral bone cavitas medullaris diameter etc.
Parameter individuation measure prostheses.

The top surface of limit protrusion 34, limiting slot 24 are interference fitted with limit protrusion 34.Limit protrusion 34 can be that square protruding or dentation are convex
Rise etc. shape.
Wherein, the material of anti-rotary knife piece 1, near end of thighbone side prosthesis component 2 and distal femur side prosthesis component 3 is closed for titanium
The alloys such as gold/vitallium/cobalt nickel/tantalum alloy/magnesium alloy.
Anti- rotary knife piece：Customized according to suffering limb femoral head neck size individuation.Anti- rotary knife leaf length is on the outside of lesser trochanter of femur
For cortex to Femoral cardlage sending down the fishbone distance, diameter is about neck of femur diameter 1/2.
Near end of thighbone side prosthesis component：Length is remaining backbone length after tumour tumor resection and the length for being driven into distal component
The sum of degree, is driven into the length i.e. length of outer cone 23 of distal component, and length is remaining backbone length correspondence after tumour tumor resection
Near-end prosthese does 21 length.Near-end prosthese does 21 a diameter of near end of thighbone pulp cavity diameter.The length of outer cone 23 in the present embodiment
Spend for 50mm.It is the posting port for inserting duct 22 that near-end prosthese, which does 21 lesser trochanter planar outboard faces, 10 ° of top rake, near-end prosthese
It is 130 ° that 21, which are done, with anti-1 angle of rotary knife piece.
Distal femur side prosthesis component：Length is 32 length summation of knurl segment length and distal end broach, and knurl segment length is corresponding
It is the length of prosthese backbone 31.The length of distal end broach 32 is about 80mm-120mm.
In addition to prosthese backbone 31 and component junction, all endosteal assembly surfaces do above spraying.
Be exactly near-end prosthese do 21 and 32 outer surface of distal end broach have hydroxyapatite coating layer.
In addition to the present invention formulates specification more than, can flexibly it develop according to different patient demand personalized customization prostheses.
According to parameter individuation measure prostheses such as patient femur's size, tumprigenicity backbone defect scope, femoral bone cavitas medullaris diameters.Specific method
It is as follows：
1st, specification measures：It is preoperative that tumor resection scope is measured according to imaging data x pieces, CT, MRI, formulate Proximal femur
Backbone defect scope, backbone diameter (specification of prosthese backbone 31)；Measuring knurl section near-end remnants femoral shaft pulp cavitys diameter, (near-end is false
The specification of soma 21)；Measure the remaining femoral shaft pulp cavity diameter (specification of distal end broach 32) in knurl section distal end；Measure lesser trochanter of femur
Planar outboard cortex to Femoral cardlage sending down the fishbone distance and neck of femur diameter (specification of anti-rotary knife piece 1)；
2nd, prosthese customization is carried out according to data above specification；
3rd, knurl section is cut off in art, as shown in figure 4, slotting from greater trochanter top Pyriform sinus, expands marrow along femoral shaft pulp cavity to distal end,
It is driven into femoral prosthesis proximal lateral component；The remaining femoral shaft pulp cavity in knurl section distal end expands marrow, is driven into femoral prosthesis distal side component；Prosthese
Closely, distal side component, which is driven into, assembles；Lesser trochanter of femur planar outboard cortex inserts anti-rotary knife to neck of femur axis location reaming
Piece.
Operation wound of the present invention is small, and operation only needs tumor resection to invade scope；Near end of thighbone lesser trochanter above structure
Do not destroy, effectively protect femoral trochanter area attachment muscle group and femoral head neck plot structure, postoperative suffering limb function effect smaller；The present invention
For bion prosthese, surface carries out painting designs, biological reconstruction is finally reached as bone trabecula is grown into, and prosthese failure probability is small,
It is small that second phase overhauls probability.It is particularly suitable for more than near end of thighbone tumprigenicity bone defect near-end lesser trochanter not involving case, Yi Jifei
Tumprigenicity near end of thighbone backbone defect case.
