The key assembly type prosthese of the present invention has following design feature:
(1) assembly type design
The segmental pattern prosthese that uses at present adopts customized type more, and namely the data such as prosthese producer key pulp cavity diameter, the remaining pulp cavity length that need to provide according to the doctor and the length of tumor that cuts bone are in advance made, and perform the operation after making again.Need the emergency case such as expanded resection scope but often occur, bone tumor inaccurate because of the pulp cavity inner diameter measurement in the art, and the flexibly strain and cause operative failure of customized type prosthese.For this problem, the invention provides a kind of key assembly type prosthese and select the bone that can satisfy key individual variation and diverse location damaged by what prosthese was rebuild any assembly of section, shank diameter and handle length and secondary attachment system.
(2) taper fit design
Dislocate in view of usually occurring the prosthese connecting portion in the prior art, the complication such as aseptic loosening easily occur in prosthesis handle, and the prosthesis handle A 1 of key assembly type prosthese provided by the invention and prosthesis handle B 2 assemblies adopt stairstepping taper fit connected mode.Taper fit is a kind of pair of ladder-type structure, so registration, convenient disassembly is being widely used aspect architectural engineering, the machinery production.This mechanics feature that connects maximum is that its stress that is subject to any direction all can be converted into the extruding force perpendicular to the conical surface, especially when loading by lower limbs, two parts assembly of prosthese connects more closely reliable under the effect of compressive stress, i.e. the larger connection of pressure is stronger.Taper ratio (cone radius: cone is high) is engineering design 1:20 commonly used.
(3) trench design
The prosthesis handle A 1 of the key assembly type prosthese of the present invention and the pulp cavity handle 13 of prosthesis handle B 2 and pulp cavity handle 23 adopt three trench design to improve its anti-rotatory.Prosthesis handle diameter>12mm, gash depth 2mm; Key normal this kind gash depth that adopts of lower limb; And prosthesis handle diameter<10mm, gash depth 1.5mm is more suitable in the key use of upper limb.Prosthesis handle adopts the circular arc design with the connecting portion of rebuilding sections.Prosthesis handle and the stress concentration of rebuilding the sections coupling part have been avoided in this design.In this prosthetic designs, the arc radius R of femoral prosthesis is 5mm, is 3mm at the prosthese radius R of humerus and ulna.Because the lower limb backbone bears heavy burden, key assembly type prosthesis handle is designed to pyramidal structure, namely the root diameter (RD) of handle is greater than the terminal 1-1.5mm of handle, and this structure can reduce the excessive and probability that causes prosthesis handle and the place of dividing a word with a hyphen at the end of a line at prosthese middle part to rupture of stress.
(4) prosthesis handle customized type design
Because height, sex difference, the length of medullary cavity, diameter and cross sectional shape all can be different, obtain satisfied matching degree in order to make prosthesis handle and pulp cavity, need to carry out the customized type design to prosthesis handle.By the measurement to femoral bone cavitas medullaris, find the 9cm to the intercondylar fossa at 2cm under the lesser trochanter of femur summit, be the medullary cavity narrow zone, diameter range is at 12 ~ 15mm; At non-narrow zone: 9cm to 4cm locates on the intercondylar fossa, the pulp cavity diameter increases to 35mm by 15mm, so need accurately to measure length and the diameter of remaining pulp cavity at iconography, the length of prosthesis handle diameter should be remaining pulp cavity the diameter at narrow place deduct 2mm, if remaining pulp cavity is in non-stenosis area pulp cavity diameter, avoid the prosthesis handle diameter that customizes too small, the remaining pulp cavity of disabling can not closely be controlled prosthese, causes in early days loosening generation of prosthese.Distal femur and proximal tibia pulp cavity are the similar trumpet-shaped lacunas that expands, and the prosthesis handle diameter is introduced into the narrowest place of pulp cavity, reach at last its enlarged diameter zone.So key assembly type prosthesis handle need be designed to rod shaped structure, when the prosthesis handle end reached its pulp cavity maximum position, the filling by bone cement fixed the protection prosthesis handle.
The beneficial effect of the key assembly type prosthese of the present invention:
(1) operation technique is relatively simple, the hospital stays is shorter: because key assembly type prosthese only needs prosthesis handle A and the fixing section of rebuilding of prosthesis handle B insertion pulp cavity bolt are got final product; and needing to install additional outer fixedly protection behind the large section allograph bone excision tumor volume reconstruction, autologous bone transplanting also needs to take out first the step such as donor bone. donor bone and has increased operating time.The key assembly type prosthese of the present invention can be widely used in defect and restore behind the dried tumor resection of long bone of limbs, such as femur, humerus, ulna etc.
(2) biomechanical strength is good, and postoperative is namely movable: maximum stress intensity, rotational stiffness and intensity behind the key assembly type prosthetic replacement obviously are better than allograph bone or bone cement+intramedullary pin is fixed.Adopt key assembly type prosthese to rebuild damaged postoperative and just can carry out positive activity in 48 hours, can bear a heavy burden fully in 10 days.
(3) prosthese is longer service life, and the early complication incidence rate is lower: prosthesis handle of the present invention is longer, and the stress that femur and bone cement are subject to after rebuilding is less, and the good stability of long handle prosthese is difficult for occuring aseptic loosening and fracture.
More than be that better enforcement of the present invention is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art make all equivalent variations or replacement also can doing under the prerequisite of spirit of the present invention, the distortion that these are equal to or replace all is included in the application's claim limited range.
