Abstract
Systems and methods for forming a handle apparatus may include shaping a strip of composite material with a flexible central portion, two grips, and two end portions. The strip may be bent onto itself such that the end portions are fastened together by a fastening device. The handle apparatus may also include a hole disposed in the flexible central portion through which a tool actuator may be passed.
Claims20
A handle apparatus for a surgical instrument comprising:
- a base component comprising a foldable strip of a first composite material that is bendable to form opposing sides of the handle apparatus, the base component being sized and arranged to be grasped and squeezed by a hand during a surgical procedure, the base component comprising:
- a first grip having a proximal end and a distal end;
- a second grip having a proximal end and a distal end;
- a flexible portion bendable to form an arcuate shape, the flexible portion extending from the proximal end of the first grip to the proximal end of the second grip;
- and
- a fastening mechanism connecting the distal end of the first grip to the distal end of the second grip.

An actuation handle apparatus for a surgical instrument comprising:
- a handle comprising:
- a base component comprising a composite material, the base component further comprising:
- a relatively more flexible region forming a flexible portion of the base component, the more flexible region being bent in a U-shape and having a first end and a second end;
- a relatively less flexible first grip extending from the first end of the more flexible region in a distal direction, the first grip having a distal end portion;
- a relatively less flexible second grip extending from the second end of the more flexible region in a distal direction, the second grip having a distal end portion;
- a fastening mechanism connecting the distal end portion of the first grip to the distal end portion of the second grip;
- and
- a tool adaptor arranged to hold a working end of an actuatable surgical tool, wherein compression of the first and second grips axially displaces the tool adaptor.

A method of forming a handle comprising:
- forming a strip from a composite material having a first end section and a second end section, wherein the composite material comprises a plurality of fibers;
- heating a section of the sheet;
- bending the sheet such that the first end section and the second end section are in physical contact;
- and
- securing the first end section to the second end section.
