Embodiment Construction

[0034] introduce

[0035] In one embodiment, the present invention is directed to a sheath for use with a scalpel cutting instrument, the sheath comprising a sheath body configured to cover a scalpel blade at a distal end of the scalpel cutting instrument. Advantageously, the sheath includes a slit formed therein extending from a first end at an edge of the sheath body to a second end adjacent to the scalpel blade so that the slit intersects / intersects the blade and the blade only exposed within the second end of the slot. The blade surfaces are not perpendicular to the slit sidewalls so that typically one sidewall will be shorter than the other. Further advantageously, the slot is configured such that the angle between the first leading sidewall (eg the shorter sidewall) of the slot and the scalpel blade at the point of intersection is greater than 105° and less than 180°. Where the slit sidewalls are parallel and the blade is straight, the angle at the intersection betwe...

Abstract

A sheath for use with a scalpel cutting device including a sheath body configured to cover a scalpel blade at a distal end of a scalpel cutting device. The sheath advantageously may include a plurality of slots formed therein. Providing two or more slots provides additional functionality and/or ease of manufacturing. A single sheath configuration including a plurality of slots (e.g., two) may be manufactured so as to be used with scalpels including somewhat different blade configurations (e.g., which may require a slightly different slot location). Such a universal sheath allows a single sheath design to be used with multiple scalpels, easing manufacture and reducing costs. In addition, depending on the particular location of the slots and the configuration of the scalpel blade, the different slots may each intersect the scalpel blade and provide different characteristics for cutting a suture.

Description

technical field [0001] The present invention relates to the field of medical instruments, such as scalpels and other surgical cutting instruments. Background technique [0002] Physicians often close patient wounds or openings (eg, during surgery) with sutures. When performing surgical procedures, it is often necessary to use a scalpel, which is then often used to cut the ends of sutures, which are often used to close wounds or openings in patient tissue. Depending on the procedural characteristics, the suture may be placed adjacent to the aorta or vein, such that any misplacement of the scalpel while cutting the suture (eg, caused by an accidental sneeze, cough, or otherwise) could be catastrophic. Alternatively, it is possible to cut the suture with scissors, but this requires an extra step and is a nuisance for the physician, who already has a scalpel at hand. [0003] Many scalpels include a safety sheath that covers the blade end of the scalpel. In order to use the b...
