Abstract

Abstract A flexible surgical instrument is provided which is ideal for providing flexibility in surgery performed through a small incision, such as arthroscopic surgery. In one embodiment, the surgical instrument is provided with an outer member having at least one opening in a distal region and a hollow inner member disposed within the outer member for transmitting force applied to the proximal end to move a cutting implement disposed at the distal end. The cutting implement is constructed and adapted to perform a cutting function at the opening in the outer member. The hollow inner member is substantially flexible between its proximal and distal ends. The outer member is provided with a predetermined flexibility and rigidity such that the outer member is provided with sufficient flexibility to be manually bent by a surgeon during and operation, and provided with sufficient rigidity to retain such bend during the continued performance of the operation with the surgical instrument.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 93 words
A method of performing a surgical procedure involving cutting in a body, comprising the steps of: inserting a flexible surgical instrument through an incision wherein said surgical instrument has markings on its outer surface; viewing the location of the flexible surgical instrument in relation to the natural curvatures of body components and determining the location of desired bends in the instrument; withdrawing said flexible instrument and manually placing bends at the noted locations along the instrument as indicated by the markings; and reinserting said flexible bent instrument into the body through said incision.
Claim 2
Independent Claim 93 words
A method of performing a surgical procedure involving cutting in a body, comprising the steps of: inserting a flexible surgical instrument through an incision wherein said surgical instrument has markings on its outer surface; viewing the location of the flexible surgical instrument in relation to the natural curvatures of body components and determining the location of desired bends in the instrument; withdrawing said flexible instrument and manually placing bends at the noted locations along the instrument as indicated by the markings; and reinserting said flexible bent instrument into the body through said incision.
Claim 3
Independent Claim 96 words
A method of performing a surgical procedure involving cutting in a body, comprising the steps of: inserting a flexible surgical instrument through an incision; viewing the location of the flexible surgical instrument in relation to natural curvatures of body components and determining the location of a desired bend in the instrument; withdrawing said flexible instrument and manually placing a bend at a noted location along the instrument, said instrument having sufficient rigidity to maintain said bend during the continued performance of the surgical procedure; and reinserting said flexible bent instrument into the body through said incision.
Claim 4
Independent Claim 96 words
A method of performing a surgical procedure involving cutting in a body, comprising the steps of: inserting a flexible surgical instrument through an incision; viewing the location of the flexible surgical instrument in relation to natural curvatures of body components and determining the location of a desired bend in the instrument; withdrawing said flexible instrument and manually placing a bend at a noted location along the instrument, said instrument having sufficient rigidity to maintain said bend during the continued performance of the surgical procedure; and reinserting said flexible bent instrument into the body through said incision.
