Abstract
A sizing forceps is provided for fixing a nerve in place, measuring the diameter of the nerve, and providing an efficient way to resect the nerve. A sizing forceps can have an upper and lower jaw with one or more aligned notches that form apertures for holding a nerve. The apertures can have predetermined sizes that can be used to measure the diameter of a nerve. A slicing slot in the upper and lower jaw allows a nerve within an aperture to be severed to obtain a non-frayed end.
Claims14
A method for measuring the diameter of a nerve tissue, the method comprising:
- A. manipulating a sizing forceps around the periphery of a nerve tissue with an upper jaw and a lower jaw separated, wherein the sizing forceps comprise:
- a first member having:
- a first handle portion with a first outer side and a first inner side,
- the lower jaw at one end of the first handle portion with a first face,
- one or more notches within the lower jaw, where the notches open onto the first face, the first outer side and the first inner side;
- a second member having:
- a second handle portion with a second outer side and a second inner side,
- the upper jaw at one end of the second handle portion with a second face,
- one or more pairing notches within the upper jaw, where the pairing notches open onto the second face, the second outer side and the second inner side;
- and
- a joint area at which the first handle portion is rotatably connected to the second handle portion;
- such that the handle portions, when manipulated along a longitudinal extent to rotate at the joint area, bring the lower jaw into alignment with the upper jaw, along a lengthwise extent, so that the first face is against the second face, thereby forming a head portion in which the notches and pairing notches come into alignment so as to form one or more apertures within the head portion;
- B. positioning the nerve tissue into at least one of the one or more notches in the lower jaw or into at least one of the one or more pairing notches in the upper jaw;
- C. manipulating the handle portions to bring the lower jaw and the upper jaw closer together, so as to begin forming an aperture;
- D. determining, as the aperture forms, if the nerve tissue diameter matches the diameter of the forming aperture;
- and
- E. repeating steps A-D until an appropriately sized aperture is formed around the nerve tissue.
