Filed:

Jun 19, 1978

Appl. No.:

5/917089

Inventors:

Jack Nestor - Miami FL

Assignee:

Nestor Engineering Associates, Inc. - Miami FL

International Classification:

A61B 1712

US Classification:

128327

Abstract:

A head encircling tourniquet comprises a frame section for surrounding a work area of the scalp connected to an opposing pneumatic pressure applying section by a pair of headsize adjustable members. The frame section has a scalp contacting, uniform pressure applying, liner and is formed with a relatively large central opening providing access to the work area while the frame section and liner controls hemostasis in the work area by pressure exerted by the pneumatic section. Opposite elongated longitudinal sides of the frame and liner are resiliently movable toward each other to close an incision or wound located in the work area for suturing while the tourniquet remains in operative position on the head.

US Classification:

Abstract:

A penile prosthesis has a minor length proximal end member separable from the major length body member enabling insertion separately into the crus and the corpus cavernosum, respectively. An element of a quick engageable connector is formed on the adjacent ends of each member for joining the members together as a unit after each member is properly positioned in the patient. Several connectors are shown. Penile posture control is achieved in the major length body member by an axially extending multiple jointed spine within a silicone rubber casing. The spine is formed with alternate tubular and spherical links retained in an articulating assembly by an axial wire. Each spherical link is formed with a pair of diametric extensions projecting into the bores of adjacent tubular links and a diametric bore through the extensions through which the wire passes. The extensions serve to limit the articulation between adjacent links. A compression spring is incorporated in the spine and, in a modification, a threaded adjustment to be performed during manufacture varies the compressive force between the links exerted by the spring and facilitates providing a selection of body members of different stiffnesses.

Abstract:

A surgical cutter for preparing recipient sites for square scalp plugs in hair transplanting has four disposable blades removably attached to the four longitudinal sides of a core having a square cross-section of predetermined dimensions corresponding to the width of each blade and to the area at the surface of the hole to be excised. Each blade projects a predetermined distance beyond the end of the core equivalent to the required depth of cut and has a sharpened inclined cutting end edge extending from a point located at one side edge inwardly to the opposite side edge in guillotine fashion. The side of the blade adjacent the point is also a sharpened cutting edge extending inwardly therefrom. One blade point is located in each corner of the square projecting from the recessed side of the adjacent blade whereby the side cutting edges are operatively exposed for cutting a subdermal portion of the scalp on rotation of the core approximately 3/4 turn after the square has been cut by the inclined end cutting edges of the blades. A handle removably accommodates the cutter in operative position and in a reverse blade protective position for handling during sterilization.
