  • Publication number: 20240074826
    Abstract: A surgical robot including at least one contact module, a control connection module, at least one first robotic arm, and at least one grip control device. A first transmission member of the control connection module drives the control module through a first transmission connecting member. A first shaft member of the first robotic arm is connected with the first transmission member while the grip control device is connected with the first robotic arm by a transmission interface. A force sensing member of the first robotic arm detects a first reaction force from the contact module so that the first robotic arm sends a feedback control signal to the grip control device to control a grip driving member to generate a force feedback for allowing a grip portion to move. Thereby, users can feel movement of the grip portion caused by the force feedback to avoid accidental iatrogenic injuries.

  • Publication number: 20110112439
    Abstract: A rotational safety syringe includes front and rear barrels rotatable with respect to each other for moving a needle holder towards the rear barrel and compressing a spring to separate a protective cover. The needle holder is fixed by an elastic press button on the needle holder and a press opening on the rear barrel. After a through hole of the front barrel is aligned with a using position, the elastic press button can be pressed to release the needle holder, and the spring can eject the needle holder towards the through hole of the front barrel to extend the needle out from the through hole of the front barrel and pierce the needle into the using position. When the spring is released, the needle holder and needle are pulled back to hide the needle into the front and rear barrels to prevent the used needle from being touched.
