Abstract
Described herein are various method of using a direct drive system to perform procedures at a distance. One exemplary method include tying a knot or suturing at a distance with a first and second end effector. The direct drive system can enable sufficient end effector dexterity, including the ability to control various degrees of freedom of end effector movement, and allow a user to perform complicated task at a distance. In one aspect the direct drive system includes flexible tools that permit access to surgical site via a natural orifice.
Claims18
A medical system comprising:
- a tool including:
- a first tool member comprising a first controller and a first control body defining a lumen, wherein the first controller includes (i) a handle coupled to a controller body and (ii) a trigger, the handle being rotatable relative to the controller body about two different axes to direct movement of a distal portion of the first control body along a first plane and a second plane different than the first plane;
- and
- a second tool member comprising a second controller and a second control body;
- wherein the second control body is disposed in the lumen of the first control body, and the second control body includes at least one mating feature complementary to at least one mating feature of the first control body;
- wherein the trigger of the first controller is coupled to the second controller, the trigger being configured to actuate the second controller;
- wherein a proximal portion of the second control body extends through the first controller;
- and
- wherein the second tool member is operable independent of operation of the first tool member, the second controller being detachable from an outer surface of the first controller, and the second control body being removable from the lumen of the first control body.

A medical system comprising:
- a tool including:
- a first tool member comprising a first controller and a first control body defining a lumen, the first controller including a handle coupled to a controller body, wherein the first controller directs movement of a distal portion of the first control body along a first plane and a second plane different than the first plane;
- and
- a second tool member comprising a second controller and a second control body;
- wherein the second control body is disposed in the lumen of the first control body;
- wherein the second controller is configured to actuate a distal portion of the second control body independent of movement of the first controller;
- and
- wherein the second controller is attached to the handle of the first controller, the handle of the first controller being configured to control movement of the second controller.
5 more elements
A medical system comprising:
- a tool including:
- a first tool member comprising a first controller and a first control body defining a lumen, wherein the first controller includes a trigger and a first handle configured to be grasped by a user to direct movement of a distal portion of the first control body along a first plane and a second plane different than the first plane;
- and
- a second tool member comprising a second controller and a second control body, the second controller including a second handle configured to be grasped by the user;
- wherein the second controller is coupled to an outer surface of the first controller so as to allow the user to manipulate the first handle and the second handle with a single hand;
- wherein the first handle or the trigger of the first controller is configured to actuate the second handle of the second controller;
- wherein the second controller is configured to actuate a distal portion of the second control body independent of movement of the first controller;
- wherein the second control body is disposed in the lumen of the first control body;
- and
- wherein the second control body includes at least one mating feature complementary to at least one mating feature of the first control body, the respective mating features allowing one of relative rotation or relative translation between the first control body and second control body while preventing the other of relative rotation or relative translation between the first control body and second control body.
