Handle design of a scalpel for stable operation thereof

A scalpel comprising:

• a blade;
• and
• a handle comprising:
• a receiving member receiving the blade therethrough;
• and
• a main portion coupled to the receiving member, the main portion having a plurality of indentations on both a first surface and a second surface thereof, each indentation of the plurality of indentations being evenly spaced from each adjacent indentation thereof and the plurality of indentations extending from a first end of the main portion proximate the receiving member and a projection of the first end on the main portion along a first length of the main portion across an entire width of the main portion, the projection of the first end being diametrically opposite to the first end along a first direction perpendicular to the first length of the main portion such that the first end and the projection of the first end delimit the width of the main portion in the first direction, the first length being greater than or equal to two-thirds of a second length of an entirety of the main portion but less than the second length, the width of the main portion being greater than or equal to five times a maximum width of the receiving member, and a thickness of the main portion being greater than or equal to 2.5 times a maximum thickness of the receiving member,
• wherein the length of the plurality of indentations extending from the first end of the main portion proximate to the receiving member is at least two-thirds of the length of the main portion,
• wherein all outer surfaces of the main portion including the first surface and the second surface are convex in shape around edges thereof,
• wherein the main portion comprises a second end farthest away from the receiving member and a third end closest to the receiving member, the third end also being proximate the first end and being free of any indentation of the plurality of indentations,
• wherein a thickness of the main portion at a top is more than a thickness at a bottom thereof to provide a surface to rest an index finger during use of the scalpel handle,
• wherein the top of the main portion is aligned with a spine of the blade and the bottom of the main portion is aligned with a cutting edge of the blade
• wherein the main portion further comprises an angled shoulder extending across the projection of the first end on the main portion and the third end such that the angled shoulder serves as a structural boundary of the main portion at the third end and the projection of the first end, the angled shoulder also being free of any indentation of the plurality of indentations therealong,
• wherein the angled shoulder is generally triangularly shaped wherein the top of the main portion is generally a side of said general triangular shape, the first and second sides of the main portion are generally lateral sides of said general triangular shape, and the bottom of the main portion is generally where the two lateral sides of said general triangular shape meet to form a corner of said general triangular shape, and
• wherein the receiving member is external to the main portion and proximate the third end and the angled shoulder of the main portion along a second direction that is an extension of the first length of the main portion such that the receiving member along the second direction is within the width of the main portion projected outside the main portion.

A scalpel handle comprising:

• a receiving member configured to receive a blade;
• and
• a main portion coupled to the receiving member, the main portion having a plurality of indentations on both a first surface and a second surface thereof, each indentation of the plurality of indentations being evenly spaced from each adjacent indentation thereof and the plurality of indentations extending from a first end proximate the receiving member and a projection of the first end on the main portion along a first length of the main portion across an entire width of the main portion, the projection of the first end being diametrically opposite to the first end along a first direction perpendicular to the first length of the main portion such that the first end and the projection of the first end delimit the width of the main portion in the first direction, the first length being greater than or equal to two-thirds of a second length of an entirety of the main portion but less than the second length, the width of the main portion being greater than or equal to five times a maximum width of the receiving member, and a thickness of the main portion being greater than or equal to 2.5 times a maximum thickness of the receiving member,
• wherein the length of the plurality of indentations extending from the first end of the main portion proximate to the receiving member is at least two-thirds of the length of the main portion,
• wherein all outer surfaces of the main portion including the first surface and the second surface are convex in shape around edges thereof,
• wherein the main portion comprises a second end farthest away from the receiving member and a third end closest to the receiving member, the third end also being proximate the first end and being free of any indentation of the plurality of indentations,
• wherein a thickness of the main portion at a top is more than a thickness at a bottom thereof to provide a surface to rest an index finger during use of the scalpel handle,
• wherein the top of the main portion is aligned with a spine of the blade and the bottom of the main portion is aligned with a cutting edge of the blade,
• wherein the main portion further comprises an angled shoulder extending across the projection of the first end on the main portion and the third end such that the angled shoulder serves as a structural boundary of the main portion at the third end and the projection of the first end, the angled shoulder also being free of any indentation of the plurality of indentations therealong,
• wherein the angled shoulder is generally triangularly shaped wherein the top of the main portion is generally a side of said general triangular shape, the first and second sides of the main portion are generally lateral sides of said general triangular shape, and the bottom of the main portion is generally where the two lateral sides of said general triangular shape meet to form a corner of said general triangular shape,
• wherein the width of the main portion tapers from the second end thereof farthest away from the receiving member to the third end thereof closest to the receiving member, the width of the main portion at the third end still being greater than or equal to five times the maximum width of the receiving member, and
• wherein the receiving member is external to the main portion and proximate the third end and the angled shoulder of the main portion along a second direction that is an extension of the first length of the main portion such that the receiving member along the second direction is within the width of the main portion projected outside the main portion.
