A positioning aid for surgical procedures has a carrier system and a template. The carrier system consists of a carrier plate, which is provided with a recess, and supports. The carrier plate can be secured to a cranial bone via the supports over an operating field for the surgical procedure. The template has a template plate which can be connected to the carrier plate in a play-free manner and which comprises a guiding aperture. The guiding aperture is arranged and oriented in the template plate, which consists of a blank, in an individualized manner according to coordinates ascertained in advance. The central longitudinal axis of the guiding aperture matches a trajectory for accessing the operating field for the surgical procedure when the carrier system and the template are assembled and the carrier system is secured to the cranial bone.

Positioning aid for surgical procedures

The invention is related to a surgical device for patient-specific guidance of at least one tool used during a surgical intervention, comprising at least the following features: a) at least one carrier system which is arranged for fixation on a bone structure of a patient, b) at least one guiding system connectable to the carrier system, the at least one guiding system comprising at least one base module and at least one guiding part for precisely defined guidance of at least one tool used during the surgical intervention, c) at least one connecting means for establishing a mechanical connection between the at least one guiding part and the at least one base module, wherein the connecting means comprises at least a non-fixed operating state and a fixed operating state, wherein in the non-fixed operating state the at least one guiding part can be adjusted relative to the base module in a patient-specific adjustment and in the fixed operating state the at least one guiding part is mechanically fixated relative to the at least one base module in the patient-specific adjustment, d) at least one mechanical interface for connecting the carrier system to the guiding system, comprising first interface means of the carrier system and second interface means of the guiding system, wherein the first interface means can be connected via form fit with the second interface means, thereby ensuring a defined adjustment of the guiding system relative to the carrier system by means of form fit. The invention is further related to a method for preparation of such a surgical guidance device.

Surgical guidance device and method for its preparation

The present invention provides an apparatus for insertion of a flexible implant into a body section of an implant recipient, the apparatus comprising an elongate guiding section having a longitudinal axis and an inner volume for removably receiving the implant, an elongate first receiving member connected at its first end to a first actuator arranged for moving the first receiving member within the guiding section in parallel to the axis of the guiding section, a first control device for controlling the actuation of the first actuator, wherein first receiving member at its second end opposite its first end carries a gripping unit for releasably gripping a proximal end of the implant, a second actuator for controlling the configuration of the implant, and a second control device for controlling the actuation of the second actuator.
