A cutting device is disclosed. The cutting device has a housing and a carriage that is movably disposed in the housing, the carriage being movable between a retracted position and an extended position. The cutting device also has a cutting member that is removably disposable in the carriage, a cover member that is removably attachable to the housing, and an urging member that operably connects the carriage and the housing. The housing includes a locking member. When the carriage is in the extended position and the cover member is attached to the housing, the locking member locks the cover member to the housing. The urging member urges the carriage to move from the extended position toward the retracted position.

A dual blade retractable tool is provided. The tool has a round tubular housing and a one-piece injection molded slide block structure. The housing has a longitudinally extending control slot and two ends with blade extension openings, one major and one minor. The one-piece structure has a major blade and a minor blade, each carried by a support. Each blade projects through the corresponding blade extension opening. One support is attached to a leaf spring cantilevered at the other end. The spring carries a control button, which projects through and moves within the slot, and a locking pin, which extends beyond the spring perpendicular to the control slot. Depressions in the tube engage and dis-engage with the locking pin as the button is pressed and moved.

A seam ripper includes a metal blade member, a handle and a slider. The blade member is supported by the handle and made of a shaft and a blade part at an end of the shaft. The slider causes the blade member to move between a retracted position and an advanced position. The shaft is housed in the handle at the retracted position. The blade part and at least a portion of the shaft are outside the handle at the advanced position. The blade part includes a cutting blade flanked by a needle portion and a ball-shaped portion. When the blade member is at the retracted position, the entirety of the needle portion is housed in the handle, and a portion of the cutting blade is exposed to the outside of the handle.

A dual blade retractable seam ripper is provided. The seam ripper has a generally cylindrical tube and a unitary injection molded slide block structure. The tube has a control slot and two capped ends with blade extension openings, one major and one minor. The unitary structure has a major seam ripping blade and a minor seam ripping blade, each carried by a support. Each blade projects through the corresponding cap opening. One support is attached to a leaf spring cantilevered at the other end. The spring carries a control button which projects through and moves within the slot and a locking pin which extends beyond the spring. Depressions in the tube engage and dis-engage with the locking pin as the button moves and is pressed.

A compact, ergonomic, lighted, retractable seam ripper is provided, having a housing, a retractable seam ripping blade, an LED, a battery, and a switch. The housing has generally planar exterior sidewalls and lower peripheral surface, a generally arcuate upper peripheral surface, a blade opening in the upper surface, and a longitudinally extending first and second rail generally parallel to the lower peripheral surface. The retractable seam ripping blade is mounted on a blade holder translatable along the first rail. A spring integral with the holder has a locking projection that engages locking depressions in the second rail. An actuating member between the spring and housing dislodges the locking projection from each of the locking depressions. The switch connects the LED to the battery when actuated.

Improved instruments (tools) and surgical techniques are provided for use in surgical procedures that treat femoroacetabular impingement of both the Cam and Pincer types.
