An electrosurgical instrument for use in cutting and / or coagulating tissue includes a dielectric material, the dielectric material being positioned in the current pathway between the tissue-treatment regions of first and second electrodes. This can be achieved by providing one or more electrode surfaces coated with a dielectric material having a reactive impedance of less than 3,000 ohms / sq. mm. at 450 kHz. The dielectric coating acts to couple the RF signal into the tissue primarily by capacitive coupling, providing a more even heating of the tissue and the elimination of “hot spot”. Examples of electrosurgical instruments employing such coated electrodes include forceps, scissors or scalpel blade instruments.

A safety scalpel blade assembly comprising a scalpel blade, a guard which extends at least about the cutting edge of the blade, and releasable attachments device which releasably attach the blade to the guard as the assembly is being attached to the scalpel handle, thereby preventing the blade from cutting a person, but which releases the blade from the guard when the blade is attached to the blade carrier of the scalpel handle.

The present invention is a dual function transfer tray that can be used for either a scalpel or a suturing needle holder with suturing needle. A scalpel slot is formed in the bottom of a relatively deep set of sloped walls. A suture needle cavity is formed above the first slot. However, at a mid-section of the scalpel slot and the half-cylindrical suture needle cavity are opposing and deep V-shaped cutaway sections in the sidewalls with a flat floor section between them. A user need never have to focus their attention for more than a split second to discern the location of the mid-section of the transfer tray. The user's thumb and forefinger are aimed at the V-shaped sidewall openings to grasp a midsection of a supported surgical sharps. The scalpel slot and half-cylindrical suture needle cavity are set relatively deep with respect to top edges of the transfer tray and the to form an open tray to prevent a user from being inadvertently injured by a scalpel blade or a suture needle. In addition, the scalpel cannot be placed in the scalpel slot unless it rests on one of its longitudinal edges, preferably the same one as that of its blade edge. Thus, a user grasping the mid-section of the scalpel handle in the cutaway and flat floor section picks up the scalpel in a ready-to-use position.

The present invention is a retractable scalpel device with two releasable latching elements. When the scalpel blade is in an extended position, each releasable latching element is accessible for depression by finger pressure to cause retraction of the extended blade. However, the releasable latching elements are located on opposite edges (top and bottom edges) of a cover housing and about halfway along its length. The releasable latching elements must be depressed at the same time for the extended scalpel blade to be retracted into the cover housing.

Proposed are a scalpel blade holder and a scalpel with a scalpel blade holder, which make it possible for a user to determine the rotation of the scalpel about the center axis of the scalpel blade holder without eye contact with the scalpel or with the scalpel blade. The handle region of the scalpel blade holder comprises three lateral faces which are disposed such that a cross-section with a substantially triangular envelope results for the handle region. The envelope of the cross-section of the handle region has substantially the form of an arc triangle whose corners are rounded. A plurality of tactile identifying features are designed as protrusions in the form of ribs extending over two of the lateral faces and running crosswise to the longitudinal axis of the scalpel blade holder. One of the tactile identifying features is designed as a recess, and is disposed on the remaining third lateral face, and extends over part of the length of the scalpel blade holder. By means of his sense of touch, the user can determine the alignment of the scalpel blade with regard to its rotation about the center axis of the scalpel blade holder.

A protective sheath for a disposable surgical scalpel includes at least three modes of operation, (i) a protective mode, (ii) an open mode, and (iii) a permanently locked mode. In the open mode, a locking strip of the scalpel handle resides in one opening of the sheath to keep the sheath substantially immobile during use of the scalpel blade. In the protective mode, the locking strip resides in a second opening of the sheath to keep the sheath substantially immobile when the scalpel blade is not in use. In the permanently locked mode, a button connected to the sheath is depressed into the second opening and engages the locking strip, thereby preventing the blade from being used and allowing the scalpel to be safely disposed.

A scalpel blade accessory and cartridge are provided wherein a tubular guard is slideable over the scalpel blade carrier between a retracted position in which the blade carrier is positioned to expose any scalpel blade associated with it for use and an extended position in which the guard covers the blade carrier and any blade thereon. The scalpel blade has a mounting slot for attachment to a lug on a standard scalpel handle for use. The blade carrier has a bridge spanning an alignment face so as to provide space for a scalpel blade between the alignment face and bridge. A blade catch cooperates with a rear end of the mounting slot to hold a relevant scalpel blade captive. The blade catch is disengagable by assembling it onto a standard handle, in use.

Devices and methods are disclosed for protecting individuals from the sharp ends of medical objects following use on a patient. Such sharp objects include hypodermic needles, scalpel blades, cannulae, trocars, and the like. The invention utilizes a disposable protective cover for the used sharp.

For cricothyrotomy and the like, a surgical device has, in one embodiment, a device body with a bi-directional scalpel, an end cap, and a tracheal hook that fits within a channel formed in the device body. With the end cap removed to expose the bi-directional scalpel blade and with the tracheal hook fully inserted within the body channel, the device can be held, e.g., in the dominant hand of an operator, and manipulated to make an opening in the patient's neck using the exposed scalpel blade. The tracheal hook can then be slid away from the device body with the hook's barbed tip entering the opening to enable the operator to easily and quickly secure the surgical airway. The design of the surgical device enables an economy of movements that otherwise would typically not be within the skill set of an operator who was not a surgeon.

Apparatus and methods for performing vasectomies are disclosed. In preferred embodiments, a clamp has a set of jaws, the distal ends of which terminate in a circular structure that is essentially a split ring. In certain embodiments, each jaw has a serrated edge that corresponds to serration on the opposite jaw, and each jaw is slightly less than a half-circle so that when closed there is a small slot or opening toward the handle side of the jaws. The jaws are adapted to grasp the vas of a patient and the slit permits a scalpel blade to cut the vas sheath longitudinally in the clamped region. Alternatively, the serrated jaws can be replaced by a single tooth on each arm of the clamp, and these teeth overlap, again leaving a single slot. Finally, in certain other embodiments, the distal ends are hooked structures and remain spaced apart even when the clamp is in the closed position.
