Abstract:
L'invention est relative à un instrument endoscopique (1) comportant un corps allongé présentant une extrémité distale (4) destinée à être introduite dans le corps du patient pour venir à proximité d'un organe interne, l'extrémité distale portant un outil (7) d'intervention sur l'organe interne. L'instrument endoscopique comporte un pied (10) solidaire de l'extrémité distale destiné à venir en appui sur l'organe interne, ainsi que des moyens de déplacement commandables (13) pour imprimer à l'outil des déplacements au moins selon des directions transverses à un axe longitudinal (X) de l'extrémité distale de l'instrument endoscopique alors que le pied est en appui contre l'organe interne.
Abstract:
L'instrument chirurgical (1) comporte : - un bras allongé (11) selon un axe longitudinal et ayant une extrémité distale (2) montée selon une liaison pivot (10) sur le bras allongé selon un axe sensiblement orthogonal à l'axe longitudinal; - un arbre d'entrainement (3) sensiblement coaxial avec le bras allongé comportant des moyens formant joint universel (4,5,7,8) situés en regard de la liaison pivot, les moyens formant joint universel comportant un joint à la Cardan; et, - un outil distal (9) solidaire de l'arbre d'entrainement et monté à rotation sur et dans le prolongement de l'extrémité distale du bras allongé, de façon à ce que l'outil distal présente deux degrés de liberté de rotation, distincts et indépendants l'un de l'autre, l'un sensiblement perpendiculaire à l'axe longitudinal et l'autre sensiblement colinéaire à un axe propre de l'outil distal.
Abstract:
The invention relates to a system for controlling with respect to a body of a patient, displacement of an intervention device having an end intended to be inserted in the body of the patient through a point of penetration comprising a base, a first portion with an arc member, a second portion with a carrier member slidably mounted on the arc member and a third portion with a holding member and a sliding member.
Abstract:
In at least one aspect, embodiments disclosed herein relate to a miniaturized scanning system to generate movement of a flexible device positioned at a distal part of a medical tool. The miniaturized scanning system comprises: an inner shaft with a longitudinal axis, adapted to guide said flexible device along said longitudinal axis, an abutment comprising an external surface and adapted to maintain said device, a pusher mechanism adapted to engage with said abutment and comprising at least one end portion adapted to contact said external surface of the abutment at a contact point, wherein said end portion is configured to translate along said longitudinal axis of the inner shaft and wherein the translation of said end portion results in a bending of the device in a bending plane defined by the longitudinal axis of the inner shaft and said contact point.
Abstract:
The invention relates to a surgical instrument (1) comprising: an elongated arm (11; 307) according to a longitudinal axis and having a distal end (2; 305) mounted with a pivot joint on the elongated arm according to an axis substantially orthogonal to the longitudinal axis; a drive shaft (3) substantially coaxial with the elongated arm comprising means forming a universal joint facing the pivot joint; and, a distal tool (9) securely fastened on the drive shaft and rotatively mounted on and in the extension of the distal end of the elongated arm, such that the distal tool has two rotational degree of freedom, distinct and independent of each other, one being around an axis substantially perpendicular to the longitudinal axis of the elongated arm and the other being around an axis substantially collinear to an own axis of the distal tool; characterised in that the elongated arm comprises a plurality of linking elements mounted in series to form the pivot joint and in that the means forming a universal joint comprise a Cardan joint.
Abstract:
The invention relates to an imaging system for following at least one surgical tool (5, 6) in an operation field inside a space (1) in the body of an animal, that comprises: at least one endoscopic camera (9) for obtaining endoscopic information of the operation field; at least one ultrasound imaging device (12) for obtaining ultrasound information on the operation field; an endoscopic and ultrasound information processing device (13), characterised in that it further comprises at least three markers (15, 16, 17) to be positioned in the operation field, said markers (15, 16, 17) being mobile relative to the tool (5, 6), and each marker being adapted to be captured both by the endoscopic camera (9) and the ultrasound imaging device (12) so that the processing means (13) can match the endoscopic information and the ultrasound information.
Abstract:
The invention relates to a device and a method to assist with the operation of an instrument by means of said device, the device and the method using leverage effects in order to calculate the data relative to any point of an instrument axis, instead of using low-accuracy sensors. Other improvements are also described that allow higher-quality usage performance for the operator, which reduces the risk of errors and simplifies the operations.
Abstract:
L'invention propose un dispositif d'assistance et un procédé d'assistance à la manipulation d'un instrument au moyen dudit dispositif, le dispositif et le procédé utilisant les effets de bras de levier pour calculer les données relatives à tout point d'un axe d'instrument, au lieu d'utiliser des capteurs peu précis. D'autres améliorations sont aussi explicitées, permettant un rendu d'utilisation de meilleure qualité pour l'opérateur, ce qui limite les risques d'erreur et simplifie les manipulations.
