Abstract
A carpal tunnel medical instrument that facilitates a two-handed carpal tunnel surgical procedure. The medical instrument of the present invention includes an elongated handle with a surgical instrument extending from one end thereof at an acute angle of about 90 degrees but in substantially the same plane as the handle. The surgical instrument is configured as either a dual channelled cannula, a cutting blade, a rasp, a probe or nerve hook.
Claims38
A carpal tunnel medical instrument, comprising:
- an elongated handle releasably attachable to and extending outwardly from either of two opposed sides of an elongated medical tool having upper and lower surfaces, and wherein, when said handle and said medical tool are releasably attached to each other, said handle extends generally normal to a longitudinal axis of said medical tool and wherein, when said handle is connected to and extends outwardly from either side of said medical tool, the top surface of said medical tool remains disposed in substantially same orientation relative to said handle thereby enhancing the versatility of the medical instrument.
A carpal tunnel medical instrument, comprising:
- an elongated handle configured to maintain a double channelled cannula in releasable association toward one end thereof, and wherein said double channelled cannula has an elongated configuration with a longitudinal axis extending generally normal to the handle when said double channelled cannula is releasably connected to said handle.
A carpal tunnel medical instrument comprising:
- an elongated handle having an ergonomically configured grip portion provided at one end thereof;
- an elongated surgical instrument having a top surface and first and second generally axially aligned ends, with the first end of said instrument being releasably secured toward a second end of said handle, and wherein the top surface of the surgical instrument is orientated in a predetermined manner relative to and such that said surgical instrument extends at about a 90 degree angle from said handle;
- and
- a manually operated locking mechanism for releasably securing the surgical instrument to the handle such that the handle can extend outwardly from either side of the surgical instrument while maintaining the predetermined orientation between the top surface of the surgical instrument and the handle.
1 more element
A carpal tunnel medical instrument, comprising:
- an elongated surgical instrument having axially aligned first and second ends with a top surface and a pair of generally parallel side surfaces;
- and
- an elongated handle for stabilizing the surgical instrument releasably connected at a first end to the handle and wherein said handle extends generally normal to said surgical instrument, the releasable connection between the housing and said surgical instrument permitting said handle to be operably connected to and yet extend outwardly from either side of the medical instrument while maintaining a consistent relationship between the top surface of the surgical instrument and the handle.
A one-piece carpal tunnel medical instrument, comprising:
- an elongated surgical instrument portion that is configured as either a double channeled cannula, a cutting blade, a probe, or a rasp, said surgical instrument having a generally planar top surface and a handle portion extending at an acute angle from the surgical instrument portion and in a plane substantially parallel to the planar top surface of the surgical instrument portion.
A carpal tunnel release medical kit, comprising:
- a plurality of individual medical instruments used in combination relative to each other during a carpal tunnel release surgical procedure, said medical instruments including a dual channeled cannula having first and second elongated and adjacent channels that are separated from each other and terminate at a substantially common length in a blunt end, with each channel being sized to allow an endoscope to pass endwise therethrough, an elongated cutting blade including a top surface extending substantially the length of said blade and having a cutting instrumentality extending upwardly from the top surface at one end of the blade and with a handle extending at an acute angle away from a side of and at the opposite end of said blade to stabilize the blade during the surgical procedure, and an elongated probe including a top surface extending substantially the length of the probe and having an instrumentality extending upwardly from the top surface at one end of the probe and a handle extending outwardly at an acute angle away from the side of and at an opposite end of the probe to stabilize the probe during the surgical procedure, and wherein the handle on the blade extends in a first direction while the handle on the probe similarly extends in the same direction but can be used in the opposite direction to promote two-handed manipulation of the surgical instruments during the surgical procedure.
