Abstract: A surgical instrument includes an articulated end having a first support link, a second link articulated with respect to the first support link about a rotation axis, and a transmission cable fixed to the second link. The first support link has at least one first convex ruled surface with straight generator lines all parallel to each other, and a second convex ruled surface with straight generator lines all parallel to each other. The transmission cable is configured to slide on both the at least one first convex ruled surface and the second convex ruled surface of the first support link when the second link rotates with respect to the first support link. The straight generator lines of the at least one first convex ruled surface are orthogonal to the straight generator lines of the second convex ruled surface.

Abstract: A tip protector, for a surgical instrument having a shaft and an instrument tip near a distal portion of the shaft, includes a tip housing for releasably receiving the instrument tip; a clamp system suitable for gripping a portion of the surgical instrument to position the tip protector; and a distal through opening at or near the distal end of the tip housing. The distal through opening has an opening size that is adjustable.

Abstract: A sterile adapter for a robotic surgery system includes a frame, a proximal coupling device suitable to form a connection with a non-sterile robotic manipulator system, a distal cavity suitable to form a connection with a surgical instrument suitable to perform robotic surgery to a patient anatomy, and a membrane having a proximal non-sterile side and a distal sterile side opposite to the proximal non-sterile side. The membrane is between the proximal coupling device and the distal cavity, and membrane is stretchable to transmit a plurality of pushing actions from the proximal non-sterile side to the distal sterile side. The frame is rigid to transmit a roll action.

Abstract: A robotic surgery system includes at least one sterile barrier assembly, at least one non-sterile robotic manipulator including a case and at least one roll motor, and at least one rolling body suitable to pivot relative to the case. At least one connector of a surgical drape of the sterile barrier assembly is coupled with the case, and at least one sterile adapter of the sterile barrier assembly is coupled with at least one rolling body of the non-sterile robotic manipulator. The at least one roll motor is suitable to move at least one rolling body together with the at least one sterile adapter in a pivoting movement with respect to the case. A gap between the at least one connector of the surgical drape and the at least one sterile adapter forms a rotatable seal, which prevents the non-sterile robotic manipulator from contaminating a sterile operatory field.

Abstract: An airtight connection device capable of receiving at least one product from at least one product discharge pipe and transmitting the product to a storage tank. The device includes a first part including at least one coupling for connecting to the product discharge pipe in an airtight manner; and a second part including a coupling for mounting the device to the storage tank in an airtight manner. The second part is coupled to the first part in an airtight manner and is capable of receiving the product from the first part and discharging the product to the storage tank. The device also includes a position sensor that can be operated during the airtight coupling to the storage tank.

Abstract: A robotic surgery assembly includes a medical instrument having a frame, a jointed device having a degree of freedom with respect of the frame, and at least one tendon made of polymer fibers configured for actuating the degree of freedom. The tendon includes a tendon endpoint connected to the medical instrument to exert a tensile load for actuating the degree of freedom.

Abstract: The invention relates to an airtight connection device having at least one product discharge pipe with means for collecting the product. The device includes a first part having means for connecting to the pipe in an airtight manner, and a second part having means for coupling to the collection means in an airtight manner. The first and second parts are coupled in an airtight manner and include additional means allowing for the discharge of the product by means of the first and second parts, from the discharge pipe to the collection means. According to the invention, the second part includes a position sensor arranged in order to be operated during the airtight coupling to the collection means.
