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

The present invention relates to a sheath for a scalpel cutting instrument comprising a sheath body configured to cover a scalpel blade at a distal end of the scalpel cutting instrument. Advantageously, the sheath may include a plurality of slits formed therein. Providing two or more slots provides additional functionality and / or ease of manufacture. A single sheath configuration including multiple slits (eg, two) may be manufactured for use with a scalpel including a slightly different blade configuration (eg, which may require a slightly different slit location). Such a universal sheath allows for a single sheath design for multiple scalpels, ease of manufacture and reduced cost. Additionally, depending on the particular location of the slit and the configuration of the scalpel blade, different slits can intersect the scalpel blade and provide different features for cutting the 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...
