Abstract: A surgical instrument comprising a handle assembly with a detachable tool assembly is disclosed. The tool assembly comprises rotatable jaws having arc defining portions near their proximal ends which define arcs having arc centers displaced from the jaws. The jaws are coupled to the distal end of an inner rod which is longitudinally translatable within an outer sleeve. When the inner rod is translated, a guide member at the distal end of the outer sleeve contacts the arc defining portion of the jaws such that each jaw rotates about the center of its arc. The handle assembly comprises a trigger which engages a translation member on the inner rod. As the trigger is rotated, the translation member carries the inner rod back and forth to actuate the jaws. The translation member is coupled to the inner rod via a coupler having a spring which limits the closing force applied to the jaws.

Abstract: A surgical tool comprises a detachable tool assembly and tool actuating handle. The tool assembly comprises a tool such as scissors having jaws pivotably mounted via a pivot pin to an inner extension. An outer sleeve around the extension carries a drive pin which engages the tool. The actuating handle retains the inner extension in a fixed position but allows the tool to rotate. Moving a trigger on the actuating handle causes the outer sleeve to translate back and forth over the extension. As the sleeve moves, the drive pin engages the tool to open and close the jaws. The handle is available in a dual-port configuration in which the tool assembly may be inserted in one of two ports.

Abstract: A suturing instrument for suturing tissue comprises an elongated housing having opposite ends. A curved suturing needle having a pointed end and a second end to which a suture is attached and supported at one end of the housing for rotational motion about an axis. A driver mechanism in the housing rotates said needle about said axis through successive revolutions, and a suture tensioner in the housing applies tension to the suture to draw the suture toward the other end of said housing following each revolution of said needle. In its operation, the instrument thus emulates the actions of a surgeon suturing manually.

Abstract: A method of improving a golf club swing by providing a planar reflecting surface having a proximal edge, a forward and back side edge, a distal edge that describes a convex arc, the perpendicular distance to which from the center of the proximal edge is dimensioned to fit between the feet of the golfer and the head of the golf club, the golfer in position to take a swing, the reflecting surface dimensioned to provide a view of the golfer from the head to the knees; andsupport means disposed beneath the distal edge of the reflecting surface of a height sufficient to tilt the reflecting surface toward the golfer to provide a view of the golfer from the head to the knees;positioning the device so that the support means and proximal edge of the reflecting surface rest on the ground;positioning the feet of the golfer on the ground adjacent the proximal edge of the reflecting surface;positioning the head of the golf club on the around adjacent the forward end of the top edge;viewing the golfer's image in the reflec

Abstract: A microsurgical stapling system for suturing delicate tissue. The system comprises a staple magazine and a stapler. The magazine has a framework to which a plurality of pre-formed staples are integrally attached in parallel, spaced-apart formation. The stapler comprises a housing, a staple support and ram assembly, a driver body and a driver assembly. The magazine is disposed within the housing and is advanced toward the staple support and ram assembly. The staple support and ram assembly comprises a front wall that engages the front edge of the leading staple in the magazine and a rear wall that engages the trailing edge of the leading staple, whereby the leading staple can be captivated between the front and rear walls. The front wall may not be movable; the rear wall is movable so that it can move down to engage the rear side of a staple which has just passed beneath the rear wall.

Abstract: The driver is disclosed for a surgical micro-suturing stapling system which does not require the use of a staple bending anvil tha must be retracted after the staple is implanted. The surgical microstapler system utilizes a unique stapler head comprising a staple magazine having a series of staples attached to and supported by a surrounding frame, apparatus for advancing the staple magazine so as to position its leading staple in a predetermined dispensing position, and staple driving apparatus for implanting the leading staple into the tissue through the ejection slot. The stapler head is adapted to be connected to the driver which provides the driving force required to cause the staple driving apparatus to separate the leading staple from the magazine and implant it into the tissue to be sutured. The driver offers the advantage that can cause the staple driving apparatus to implant a staple at a velocity in excess of the ability of tissue to respond dynamically under the force of a staple being implanted.

Abstract: A surgical microstapler is disclosed which does not require the use of a staple bending anvil that must be retracted after the staple is implanted. The surgical microstapler utilizes a stapler head comprising a staple magazine that consists of a series of staples attached to and supported by a plurality of frame members. The stables have a predetermined shape characterized by a spine portion and two opposite legs. The staples and frame members are formed as part of a sheet metal continuum and are joined by a plurality of tabs which coact with the frame members to hold the staples in proper spaced relationship within the magazine. The stapler head also comprises means for advancing the magazine so as to position its leading staple in a predetermined dispensing position in line with an ejection slot through which the staple is ejected and inserted into tissue, and staple driving means for implanting the leading staple.
