Abstract
A medical observation device includes an imaging unit configured to photograph an image of an operation site, and a holding unit configured to be connected with the imaging unit and have rotary shafts which are operable with at least six degrees of freedom. Among the rotary shafts, at least two shafts are active shafts whose driving is controlled based on states of the rotary shafts, and at least one shaft is a passive shaft which is rotated according to direct external manipulation accompanying contact.
Claims19
A medical observation device comprising:
- an imager to photograph an image of an operation site;
- a holder to be coupled with the imager and that includes rotary shafts which are operable with at least six degrees of freedom, wherein, among the rotary shafts, at least two of the rotary shafts are motorized shafts;
- and
- processing circuitry configured to control driving of the motorized shafts based on states of the rotary shafts such that the imager photographs an observation target and continues to photograph a same observation target through and after a movement of the imager to a different position,
- wherein the motorized shafts include a first rotary shaft which is orthogonal to an optical axis of the imager and a second rotary shaft which is orthogonal to the optical axis and the first rotary shaft.
A medical observation device comprising:
- an imager to photograph an image of an operation site;
- and
- a holder to be coupled with the imager and that includes rotary shafts which are operable with at least six degrees of freedom, wherein, among the rotary shafts, at least two of the rotary shafts, which are a first rotary shaft which is orthogonal to an optical axis of the imager and a second rotary shaft which is orthogonal to the optical axis and the first rotary shaft, are motorized shafts;
- and
- processing circuitry configured to control driving of the motorized shafts based on states of the rotary shafts the imager photographs an observation target and continues to photograph a same observation target through and after a movement of the imager to a different position,
- wherein the first and second rotary shafts include encoders to detect rotation angles of the first and second rotary shafts, force sensors to detect external force loaded at least on the first and second rotary shafts, and actuators to drive rotation of the first and second rotary shafts.
A medical observation device comprising:
- an imager to photograph an image of an operation site;
- a holder to be coupled with the imager and that includes rotary shafts which are operable with at least six degrees of freedom, wherein, among the rotary shafts, at least two of the rotary shafts are active shafts;
- and
- processing circuitry configured to control driving of the active shafts based on states of the rotary shafts such that the imager photographs an observation target and continues to photograph a same observation target through and after a movement of the imager to a different position,
- wherein a direct external manipulation changes a state of at least one passive shaft and a rotation of the active shafts are controlled by the processing circuitry based on the state of the at least one passive shaft to modify an imaging direction, and
- wherein the motorized shafts include a first rotary shaft which is orthogonal to an optical axis of the imager and a second rotary shaft which is orthogonal to the optical axis and the first rotary shaft.
