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.
Claims30
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;
- one or more motors operatively coupled to the magazine, the one or more motors configured to be actuated to move the magazine relative to the body portion;
- 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;
- and
- a user interface operatively coupled to the one or more motors, the user interface configured to receive user input indicative of the selected chamber,
- wherein the one or more motors are configured to actuate the magazine to align the selected chamber with the proximal end of the elongated shaft based on the user input.

A surgical device comprising:
- a body portion comprising a worm gear;
- 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 rack and an actuation rod disposed within a lumen of the rack, the rack comprising a geared outer surface operatively coupled to a pinion gear operatively coupled to the worm gear, the worm gear configured to be actuated to cause rotation of the pinion gear to thereby cause translational movement of the rack via a geared connection between the pinion gear and the geared outer surface,
- wherein the tool activation mechanism is configured to transition between a retracted configuration within the body portion where a distal region of the tool activation mechanism is disposed proximal to the selected chamber, and an extended configuration where the distal region is releasably 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, and
- wherein the rack and the actuation rod are configured to move together as the tool activation mechanism transitions between the retracted configuration and the extended configuration.
