Title (EN) INTRAOPERATIVE JOINT FORCE MEASURING DEVICE, SYSTEM AND METHOD
(FR) DISPOSITIF, SYSTEME ET PROCEDE PEROPERATOIRE DE MESURE DES FORCES D'ARTICULATION
Abstract:
(EN) A surgical device (100) for joint replacement surgery includes an intraoperative joint head (110) having a stem attachment structure (120) where the stem attachment structure (120) may be removably attachable to a stem (130) and a force sensor housed by the joint head (110) for measuring in vivo forces during surgery. The in vivo forces may be generated by one or more of tension provided by soft tissue, load application during surgery, limb movement during surgery, and a combination thereof. Also, the joint head (110) may provide a cavity (140) where the stem attachment structure (120) houses the force sensor and may be removably insertable in the joint head cavity (140). A method of performing joint replacement surgery includes installing an intraoperative joint head (110) having a force sensor housed by the joint head (110) and a stem attachment structure (120), the stem attachment structure (120) being removably attachable to a stem (130), measuring joint forces, and adjusting an implant parameter based on the measured joint forces.
(FR) La présente invention concerne un dispositif chirurgical pour remplacement d'articulation. Il comprend une tête d'articulation peropératoire à structure de montage de tige susceptible de montage amovible sur la tige, avec un capteur de force logé dans la tête de façon à mesurer in vivo les forces pendant l'intervention. Ces forces peuvent être produite par au moins une tension réalisée par des tissus mous, par l'application d'une force pendant l'intervention, par le mouvement du membre pendant l'intervention, et par l'une des combinaisons de ces raisons. De même, la tête comporte une cavité dans laquelle la structure de montage de tige héberge le capteur de force et vient s'insérer amovible dans la cavité de tête. L'invention concerne également un procédé se rapportant à cette intervention par installation d'une tête d'articulation peropératoire comportant un capteur de force logé dans la tête, avec une structure de montage de tige se montant amovible sur une tige, par mesure des forces de l'articulation, et réglage d'un paramètre d'implant sur la base des forces d'articulation mesurées.
