Abstract:
The present disclosure relates to high dexterity manipulation systems for microsurgical procedures. The surgical system includes a master apparatus controllably coupled to a slave apparatus configured to couple to a patient's head with a dual tripod structure having two pluralities of linear actuator links pivotally supporting a surgical tool shaft. The motions of the linear actuator links are controlled to provide at least 6 degrees of freedom for the surgical tool shaft. The slave apparatus may further include a redundant axis rotatable tool shaft, thus enabling 7 degrees of freedom for a surgical tool. The surgical system includes sensors enabling forces of interaction between the slave apparatus and its environment to be reflected back to the master apparatus. Forces imparted onto the master apparatus by an operator can be fed forward to control the slave apparatus and scaled down to reduce the forces on target tissues.
