Abstract

A head-mounted assembly provides simultaneous recording of 3D stereo video of surgical procedures. In addition, the head-mounted assembly provides a 3D stereo surgical video system that may be co-axial to a surgeon's bi-nocular optical view trajectory. The head-mounted assembly includes a head-mountable structure, a first telescope and a second telescope, and a first video camera and a second video camera. The head-mountable structure is mounted on the head of a user. The first telescope, the first video camera, the second telescope, and the second video camera are secured to the head-mountable structure. The first video camera is positioned in relation to a first line of sight, as viewed, through the first telescope, by a first eye of the user. On the other hand, the second video camera is positioned in relation to a second line of sight, as viewed, through the second telescope, by a second eye of the user.

Dependent claims

A head-mounted assembly comprising:

a head-mounted structure;
a first housing structure and a second housing structure;
a coupling structure;
a first optically magnifying structure and a second optically magnifying structure;
and
a first video camera structure and a second video camera structure,
wherein the head-mounted structure is constructed and arranged to be mounted on the head of a user;
wherein the first optically magnifying structure and the first video camera structure are constructed and arranged to be secured to the first housing structure,
wherein the second optically magnifying structure and the second video camera structure are constructed and arranged to be secured to the second housing structure,
wherein the first housing structure and the second housing structure are constructed and arranged to be secured to the head-mounted structure, and to be coupled to the coupling structure such that one of the first housing structure and the second housing structure can be moved with respect to the other one of the first housing structure and the second housing structure;
wherein the first video camera structure is constructed and arranged to be focused based on a first line of sight, as viewed, through the first optically magnifying structure, by a first eye of the user, and
wherein the second video camera structure is constructed and arranged to be focused based on a second line of sight, as viewed, through the second optically magnifying structure, by a second eye of the user.

A method comprising:

producing a first video signal corresponding to a first line of sight, as viewed, through a first optically magnifying structure, by a first eye of a user;
producing a second video signal corresponding to a second line of sight, as viewed, through a second optically magnifying structure, by a second eye of the user;
and
displaying, through a display structure, a three dimensional video image corresponding to the first video signal and the second video signal,
wherein the first optically magnifying structure and the second optically magnifying structure are secured to a head-mounted structure mounted on the head of the user, and coupled to a coupling structure such that one of the first optically magnifying structure and the second optically magnifying structure can be moved with respect to the other one of the first optically magnifying structure and the second optically magnifying structure.
