Abstract: A surgical instrument for endoscopic surgery having a solid or transparent body and open windows on each of the opposing sides at the distal end, proximate a top open region. The open windows can be arcs or other configurations either open or with bars which are generally integral with the top and extend across the windows. An integrated tissue retractor spring, once activated, extends above the open region and when not activated rests within the open region. A marking member, that can be in fluid contact with a marking reservoir, can be placed at the distal end of the body. In another embodiment the body can be curved using a flexible blade shaft. In a further embodiment the handle has a linear body, containing a blade activation mechanism, at least one activation trigger, and a connector means.

Abstract: A flexible compression screw having multiple segments, one or more of which are flexible and one or more segments that also include threads. The flexibility is created through the use of at least one helical slot formed generally in the center segment of the element. Additional flexible segments also have at least one helical slot in either the same helical rotation and pattern or in an opposite rotation and/or different pattern. An elastomeric material can fill the hollow body, extend into the slots and/or encompass the exterior. The flexible screw can have a hollow body, including leading and trailing edge, or can have a partially hollow body.

Abstract: A fibrous, preferably crosslinked, graft material is pre-packaged in a sterile, water tight package to permit a surgeon with easy access to a safe, durable fill material that can significantly reduce the appearance of wrinkles on the skin surface. After performing a subcutaneous dissection under a wrinkle region to release the connections between the region and underlying planes of subcutaneous fat, muscle and the fibrotic bed, the surgeon fills a portion of the wrinkle region with the fibrous graft material to eliminate or reduce the appearance of wrinkles, folds and scars. The fibrous graft material may be housed in a tube that can be inserted under the skin, where the fibrous graft material is detachable and extrudable from the tube in situ at the wrinkle region.

Abstract: Energy absorption tubing is provided between the cannula and the suction tubing connected to a vacuum in a Power Assisted Lipoplasty device. The energy absorption tubing isolates the vibration or keeps the motion away from the handpiece, making the handpiece more comfortable to hold for the surgeon.

Abstract: Bone mills and templates for use in during bone resectioning is provided. The templates have a flat upper surface or an interior track, and the mill has an edge that rides on top of the upper surface or within the groove. The template thus guides the mill during bone resectioning, delimiting the area and depth of the bone that is removed. Additional bone mills with supports and frames that control the depth of milling are also provided.

Abstract: Provided are devices and a method for removing skin while causing minimal damage to underlying vascular tissue. An epithelium cutter for removing skin has a handle with a V-shaped blade disposed at one end of the handle. Inner surfaces of the V-shaped blade are sharp, and face away from the handle. In operation, the skin is pulled upwards with tweezers so that it forms a mound, and the V-shaped blade is disposed around the skin mound. Skin removal is initiated by pushing the sharp inner surfaces of the V-shaped blade into the skin mound. The epithelium cutter can remove an arbitrarily long strip of skin. Optionally, to make skin removal easier, the skin can be pre-cut with a rake cutter having 2, 3 or more parallel blades. In this case, a distance between the parallel blades is selected to match a cutting width of the V-shaped blade.

Abstract: A cannula having a bore extending along a length thereof. The cannula includes a vent hole. A plug with an air passage may be inserted within the vent hole such that the air passage is in fluid communication with the bore of the cannula.

Abstract: A power assisted liposuction/lipoinjection handpiece includes a handle (12) which provides power to reciprocate a cannula (10) back and forth during surgery. The cannula (10) can be connected to the handle (12) by a connector (24) that is affixed to, integrally formed with, or selectively joinable to a reciprocating member (14). Benefits in sterilization, distribution and surgical use can be realized when the cannula (10) and connector (24) are joined together, such that the surgeon merely needs to remove the cannula (10) from the package and connect it to a reciprocating member of a powered handle (12). The handle (12) may be configured such that the reciprocating member (14) is selectively detachable; thereby, allowing the handle (12) to be used for additional surgical procedures such as sawing or drilling. A vacuum hose (26) is connected to the cannula (10) such that vacuum pressure can be exerted through the cannula (10) for aspirating severed fat tissue.

Abstract: A pulsed lavage attachment (40) is secured to a conventional, powered, modular, surgical hand piece (42) to allow a pulsed lavage delivery set (18) to be connected to and controlled by the hand piece (42), thereby eliminating the need for dedicated air or power lines and a dedicated pulsed lavage hand piece in the operating room. The pulsed lavage attachment (40) includes an internal driver (52) which mates with an output driver of the hand piece (42) and is axially rotatable by the output driver. A cam driver (56) connected to the internal driver (52) by pegs or other suitable means, and is rotatable therewith, has a cammed surface (62). A bearing member (64) rides on the cammed surface (62), and drives shaft (66) in an axial direction. Membrane (68) flexes outward to actuate a connecter (24) of the pulsed lavage delivery set (18) to actuate an internal pumping cartridge therein.
