Abstract

The adaptable isoelastic hip joint endoprosthesis has a joint part and a stem formed by at least two longitudinal rods between which there is arranged a spacer core in their upper part in order to permit the shape of the stem to be adapted to the shape of the cavity in the femur. <IMAGE>

Description

Vynález se týká adaptabilní izoelastické kyčelní endoprotézy.The invention relates to adaptable isoelastic hip endoprosthesis.

Dosud užívané kyčelní endoprotézy jsou tvořeny jedním prutem nebo svazkem prutů, které jsou na obou koncích vzájemně pevně spojeny. Vzhledem к tomu, že jde o pruty tuhé a v některých případech pevně spojené i v příčném směru, vytvářejí tak rigidní systém.The hip endoprostheses used hitherto consist of one rod or a bundle of rods which are firmly connected to each other at both ends. Being rigid and, in some cases, rigidly connected in the transverse direction, they form a rigid system.

Uvedené nedostatky odstraňuje adaptabilní izoelastická kyčelní, endoprotéza, sestávající z hlavice, připojené ke dříku endoprotézy podle vynálezu. Jeho podstata spočívá v tom, že dřík je tvořen nejméně dvěma podélnými pruty mezi nimiž je v jejich horní polovině umístěno distanční jádro. Podélné pruty mohou mít proměnný průřez a mohou být nestejně dlouhé. Podélné pruty mohou být s výhodou na svých dolních koncích opatřeny stabilizačním tělískem. Distanční jádro může být s podélnými pruty pevně spojeno a může být opatřeno fixačními členy, například výstupky nebo otvory.These drawbacks are overcome by an adaptable isoelastic hip hip prosthesis consisting of a head attached to the shaft of an endoprosthesis of the invention. Its essence is that the shaft is formed by at least two longitudinal rods between which a spacer core is placed in their upper half. The longitudinal members may have a variable cross-section and may be of unequal length. The longitudinal bars can advantageously be provided at their lower ends with a stabilizing body. The spacer core may be rigidly connected to the longitudinal members and may be provided with fixation members such as protrusions or openings.

Hlavní4 výhodou endoprotézy podle vynálezu je dřík sestavený z jednotlivých a vzájemně nevázaných prutů, které se musí v důsledku své elasticity přizpůsobit tvaru dřeňového kanálu femuru, ale i proměnlivému přenosu zatížení do femuru při neustále se měnících podmínkách vnějšího zatížení. Vzájemně nevázané pruty mají možnost zaujmout optimální polohu ve směrech toku hlavních napětí. 4 The main advantage of the endoprosthesis according to the invention the stem is made up of individual and mutually unbound members, which must be due to their elasticity, adapt to the shape of the medullary canal of the femur, but also a varying load transfer to the femur at a constantly changing conditions of external load. Unbound rods have the possibility to assume an optimal position in the directions of main stress flow.

Vynález a jeho účinky jsou blíže vysvětleny v popise příkladu jeho provedení podle přiloženého výkresu, kde obr. 1 znázorňuje v náryse celkový pohled na adaptabilní izoelastickou kyčelní endoprotézu podle vynálezu, obr. 2 pak znázorňuje průřez v místě A-A a obr. 3 průřez v místě B-B u adaptabilní izoelastické kyčelní endoprotézy podle vynálezu.BRIEF DESCRIPTION OF THE DRAWINGS The invention and its effects are explained in more detail in the accompanying drawing, in which: Figure 1 is a front elevational view of an adaptable isoelastic hip prosthesis according to the invention; in adaptable isoelastic hip endoprosthesis according to the invention.

Endoprotéza podle vynálezu sestává z hlavice 5 а к ní připojené příruby £. Do příruby £ jsou vetknuty dva nebo více podélných prutů £, tvořící adaptabilní dřík. Podélné pruty £ jsou ve své horní části pod přírubou £ od sebe trvale oddáleny distančním jádrem 2. Podélné pruty £ mohou být stejně dlouhé nebo nestejně dlouhé a mohou mít konstantní nebo proměnný průřez. Na volném konci jsou prostorově rozšířeny stabilizačním tělískem 3, například ve tvaru kapky, kuličky, elipsoidu nebo destičky. Pod přírubou £ jsou podélné pruty £ od sebe oddáleny distančním jádrem 2 z plastické hmoty, biokeramiky, kovu nebo jiného materiálu podobných vlastností. Distanční jádro 2 je plnostěnné nebo různě perforované a s podélnými pruty £ je pevně spojen nebo je к nim kluzně přiloženo. Distanční jádro 2 má tvar Ι-profilu, T-profilu# křížového profilu nebo obdélníkového profilu a je opatřeno fixačními členy £ například výstupky nebo otvory.The endoprosthesis according to the invention consists of a head 5 and a connected flange 6. Two or more longitudinal rods 6 forming an adaptable shaft are fixed into the flange. The longitudinal members 4 are permanently spaced apart from each other by a spacer core 2 in their upper part below the flange. At the free end, they are spatially extended by a stabilizing body 3, for example in the form of a droplet, a ball, an ellipsoid or a plate. Below the flange 4, the longitudinal rods 4 are spaced apart by a spacer core 2 of plastic, bioceramic, metal or other material of similar properties. The spacer core 2 is solid-walled or perforated in various ways and is rigidly connected or slidably attached to the longitudinal rods. The spacer core 2 has the shape of a profilu-profile, a T-profile # of a cross-section or a rectangular profile and is provided with fixing members 6, for example protrusions or openings.

Endoprotéza podle vynálezu je využitelná v lékařství v oboru ortopedie a traumatologie.The endoprosthesis of the invention is useful in medicine in the field of orthopedics and traumatology.
