A surgical instrument holding device includes a holding body, an adapter, a separator, and a driving body. The holding body holds a surgical instrument. The adapter receives the surgical instrument and is disposed between the surgical instrument and the holding body. The separator is provided between the adapter and the holding body and includes a receiving portion that receives the adapter. The driving body supplies a driving force to the holding body to drive the surgical instrument. The adapter includes a pressing portion and an engaging portion, and when the receiving portion of the separator receives the adapter, the pressing portion contacts the receiving portion and the engaging portion engages the receiving portion to attach the adapter to the separator.

Surgical instrument holding device and surgery assisting device

A force sense notification device includes a speaker and a control device that receives a measurement signal indicating a magnitude of a force exerted on a surgical instrument, generates sound information based on the magnitude of the force, and outputs the sound information through the speaker.

Force sense notification device and force sense notification method

An optical unit includes: a first actuator for driving a first movable barrel; a second actuator for driving a second movable barrel; a first contact surface for defining a first frontmost end position which the first movable barrel takes; a second contact surface for defining a rearmost end position which the first movable barrel takes; a third contact surface for defining a frontmost end position which the second movable barrel takes; a fourth contact surface for defining a rearmost end position which the second movable barrel takes; and a contact member formed on the first movable barrel, having a fifth contact surface which is brought into contact with a distal end surface of the second movable barrel, and defining a first stop position or a second stop position.

Optical unit and endoscope

A stereo image pickup unit includes: first and second image pickup apparatuses including first and second image pickup devices and first and second mount boards, the image pickup apparatuses being formed in a same shape each other; and a holding frame for holding the first and second image pickup devices, the first and second mount boards including non-mounting surfaces perpendicular to rear surfaces of the first and second image pickup devices and projecting toward an outer side of projection surfaces of the first and second image pickup devices, the holding frame holding the first and second image pickup apparatuses such that the non-mounting surfaces are opposed to each other on a parallax direction inner side.

Stereo image pickup unit

An optical unit includes: a lens holding frame configured to hold an objective optical system; an image pickup device holding frame configured to hold an image pickup device including a light receiving section that detects an object image formed by the objective optical system, to which a first holding frame is interpolated and fitted; a welding section provided on a fitting section of the lens holding frame and the image pickup device holding frame, configured to fix the lens holding frame and the image pickup device holding frame at a fitting position at which an image forming surface of the object image by the objective optical system and the light receiving section are made to coincide; and a bonding material configured to fill a gap formed between the lens holding frame and the image pickup device holding frame.
