Abstract
Systems and methods for performing surgery are provided, which permit multiple tool tips to be interchanged within an instrument shaft during a minimally invasive procedure. The surgical device holds a plurality of interchangeable tool tips such that a selected tool tip from a chamber of a magazine can be mounted at the distal end of an elongated shaft for a laparoscopic surgery. In this manner, multiple tool types can be interchanged within a shaft without having to remove the instrument from the patient for tool changes, thereby increasing surgical efficiencies and reducing the number of tools needed for a procedure.
Claims27
A surgical device comprising:
- a body portion;
- an elongated shaft having a proximal end coupled to the body portion, a distal end, and a lumen extending therebetween;
- a magazine coupled to the body portion and comprising a plurality of chambers, each chamber configured to receive an interchangeable tool tip therein, the magazine configured to be selectively actuated to align a selected chamber of the plurality of chambers with the proximal end of the elongated shaft;
- and
- a tool activation mechanism comprising a distal region configured to be releasably coupled to the interchangeable tool tip of the selected chamber, the tool activation mechanism configured to transition between a retracted configuration within the body portion where the distal region is disposed proximal to the selected chamber, and an extended configuration where the distal region is coupled to the interchangeable tool tip of the selected chamber and extends through the lumen of the elongated shaft such that the interchangeable tool tip is mounted at the distal end of the elongated shaft.
