Abstract
The present invention relates to a contoured scalpel handle. The contoured shape of the handle provides for increased contact area with the user's hand using a larger diameter central portion and a smaller diameter trough. The generally circular cross-section allows rotation of the angle of the blade relative to the tissue without the need to change the grip on the handle. The contoured handle can be used as an adapter sleeve in which a scalpel handle can be inserted or can include a blade mounting element on which a blade is directly mounted.
Claims24
A surgical scalpel handle comprising:
- a surgical scalpel handle having a contoured handle surface to be held in a hand of a user, the contoured handle surface having a distal trough, a larger diameter central portion having a circular cross-section and a proximal trough extending about a longitudinal axis of the scalpel handle;
- and
- a surgical blade mounting element adapted to receive a surgical blade that is mountable on the mounting element, the mounting element being positioned on a post that extends from a distal end of the scalpel handle such that the user can rotate the scalpel handle in the user's hand to rotate the mounted surgical blade during cutting of tissue.
