This medical manipulator is provided with: an opening/closing drive transmission unit that transmits driving force for an opening/closing operation to a tip operation section from a handle side; and a rotary driving transmission unit that transmits rotary force for a rolling operation to the tip operation section from the handle. The rotary driving transmission unit has: a rolling drive transmission tube disposed rotatably within a shaft; a bevel gear provided to the joint between the shaft and the tip operation section; and a rotating sleeve that meshes with the bevel gear. A pull-wire having flexibility and configuring a portion of the opening/closing drive transmission unit extends through the inside of the joint to the inside of the tip operation section.

An object of the present invention is to provide a simple measure which can suppress freshness deterioration of a myoglobin-containing food. The present invention relates to a myoglobin-containing food freshness deterioration suppressing material for suppressing freshness deterioration of a myoglobin-containing food, comprising: a substrate comprising a polymer; and an antioxidant with which at least a part of the surface of the substrate is covered, and/or an antioxidant supported in a layer forming at least a part of the surface of the substrate; wherein 0.01 g/mor more and 20 g/mor less of the antioxidant is included relative to the area of the part in which the antioxidant is present, of the surface of the substrate.

Myoglobin-containing food freshness deterioration suppressing material and use thereof

A medical manipulator wherein a first section provided with a driven coupling is detachably attached to a second section provided with a driving coupling that includes a drive source and is driven by the drive source. The driving coupling and the driven coupling are fitted to each other to transmit the drive force from the drive source to a tip-end operation part. In at least one coupling among the driving coupling and the driven coupling, tooth ends on the side where the fitting of the driving coupling and the driven coupling begins when the first section and the second section are connected become thinner towards the axial-direction end surface.

A switch mechanism for a medical manipulator, the switch mechanism including a moveable switching operation part, moving-side contacts provided to the switching operation part, and fixed-side contacts capable of contacting the moving-side contacts. At least the electrical-contact sections of the moving-side contacts and of the fixed-side contacts are formed from a corrosion-resistant material.

A medical manipulator is provided with a brake release mechanism. The brake release mechanism is provided with a release button which is provided on a tilt wheel, and a lever mechanism which has at least one portion arranged on the inside of the tilt wheel and which is pressed when the release button moves inwards. By the action of the lever mechanism when the release button is operated, braking by a brake mechanism is released.

Brake release mechanism and medical manipulator provided with same

A medical manipulator includes: a manipulator body that has a handle; a drive unit that can be detachably attached to the handle and has a drive source; a guide mechanism that guides the movement of the drive unit when the drive unit is attached to or detached from the handle; a motive force-transmitting coupling that has a driving member and a driven member, and transmits the drive force from the drive source to the handle side; and an electrical connection mechanism that electrically connects the handle and the drive unit when the drive unit is mounted to the handle.

A slip ring mechanism for a medical manipulator, the slip ring mechanism including: a rotating rod that rotates together with a drive shaft; rotating terminals that are positioned so as to be coaxial to the rotating rod; conductive members that contact the rotating terminals and are electrically connected to an end effector; holding members that hold the conductive members such that the conductive members are sandwiched between the holding members and the rotating terminals; and contact terminals that contact the rotating terminals so as to be capable of rotating and sliding relative thereto.

A medical manipulator is provided with a brake mechanism. The brake mechanism is provided with a brake rotor and a brake shoe which can contact the outer periphery of the brake rotor. On the outer periphery of the brake rotor, a first gear is provided along the circumference. On the portion of the brake shoe which is opposite of the outer periphery of the brake rotor, a second gear is provided which can mesh with the first gear.

Brake mechanism and medical manipulator provided with same

A medical manipulator includes: a manipulator body that has a handle; a drive unit that can be detachably attached to the handle; and an attachment limiting mechanism that is provided to the handle. When the number of times that the drive unit has been attached to and detached from the handle reaches a set number, the attachment limiting mechanism prevents the mounting of the drive unit to the handle. The attachment limiting mechanism has a counting mechanism and a stopper. The counting mechanism counts the number of times that the drive unit is attached and detached. When the count reaches a set number, the stopper is made to protrude into a mounting hole in the handle so as to prevent the insertion of the drive unit into the mounting hole.

Medical manipulator with attachment limiting mechanism including counting mechanism

A medical manipulator includes a surgical tool that has an end effector at a distal end and a drive unit that is detachable from a handle of the surgical tool. In a state where the drive unit is mounted on the handle, when a manipulation lever is manipulated, a driving force of a motor is transmitted to the handle, and the end effector is operated. Even in a state where the drive unit is detached from the handle, the surgical tool can be independently used by a manual manipulation.

A medical manipulator has a distal-end working unit including an end effector. The distal-end working unit has a rotor having a hollow tube rotatable in unison with the end effector and a rotational support tube having a posture variable with respect to the shaft. The rotor is rotatably supported by an inner circumferential surface of the rotational support tube. Engaging members that are disposed in side holes formed in the rotational support tube have inner ends inserted in an annular groove.

A suturing and ligating method includes a needle piercing step of inserting a needle of a suture-needle assembly through a tissue in a body cavity, a needle gripping step of gripping the needle with a first gripper, a winding step of winding a suture strand of the suture-needle assembly in at least one turn around a first distal-end working unit by rolling the first distal-end working unit in at least one revolution, a transferring step of transferring the suture-needle assembly from the first gripper to a second gripper, a suture strand gripping step of gripping a portion of the suture strand that has not passed through the tissue, with the first gripper, a pulling step of pulling the first distal-end working unit out of a loop of the suture strand, and a tightening step of forming a knot of the suture strand.

Suturing and ligating method

A carbon-containing modified polystyrene type resin particle of the present invention includes: a carbon-containing polypropylene type resin, and a polystyrene type resin in an amount of not less than 100 parts by weight but less than 400 parts by weight per 100 parts by weight of the carbon-containing polypropylene type resin, wherein the polystyrene type resin ratio at the central part of the particle is at least 1.2 times the polystyrene type resin ratio of the overall particle, the polystyrene type resin ratio being calculated by using the ratio (D698/D1376) of absorbances at 698 cmand 1376 cmwhich are obtained by infrared absorption spectra measured by ATR infrared spectroscopic analysis.
