Patent number: 6626925Abstract: A shielded surgical scalpel includes an elongate handle defining a longitudinal axis and having a proximal portion and a distal portion. A blade is fixedly attached to the handle. A shield is mounted onto the handle. The shield is movable between a distal position where the shield prevents inadvertent access to the blade and a proximal position where the shield exposes the blade for use.Type: GrantFiled: March 29, 2001Date of Patent: September 30, 2003Assignee: Becton Dickinson and CompanyInventors: Craig D. Newman, Charles G. Hwang, Richard A. Flowers, Glade H. Howell, Simon Cohn

Patent number: 5938676Abstract: A scalpel of the present invention includes an elongate handle defining a longitudinal axis and having a proximal end and a distal end. The scalpel of the invention further includes a cartridge that is removably mounted to the handle. The cartridge has blade holder with a proximal end and a distal end with a blade fixedly attached that is disposed so that the blade projects distally outwardly when the cartridge is mounted to the handle. The cartridge also includes a shield that is slidably mounted onto the blade holder for movement between a distal position where the shield substantially prevents inadvertent access to the blade and a proximal position where the shield substantially surrounds a portion of the handle and the blade is exposed for use. The cartridge is releasably mountable on the handle. The shield is substantially prevented from movement to the proximal position unless the cartridge is mounted on the handle and not dismountable from the handle unless the shield is in the distal position.Type: GrantFiled: March 31, 1998Date of Patent: August 17, 1999Assignee: Becton, Dickinson & CompanyInventors: Simon Cohn, Paul Di Cesare, Michael J. Carter, Jon D. Swenson, Ann C. Eckert, Noel Gharibian, Craig D. Newman

Patent number: 5827309Abstract: This invention relates to an improved guarded surgical scalpel having a movable guard that can be retracted to expose the blade and that can be extended to cover the sharp cutting edge of the blade. The guard is telescopically mounted inside the blade handle and includes a deflectable top wall portion that holds a detent pin or that defines a radially extending flange. This detent pin or flange engages a slot having upturned ends formed in at least one side wall of the blade handle. The detent pin or flange is biased upwardly into the upturned ends of the slot to hold the guard in the retracted or extended position. The blade can include a tang having a notch formed therein. The distal end of one sidewall of the guard can be formed with a complementary notch such that when the distal end of the sidewall of the guard engages the proximal end of the blade, forward movement of the guard forces the blade off of the scalpel.Type: GrantFiled: October 19, 1995Date of Patent: October 27, 1998Assignee: Becton, Dickinson and CompanyInventors: Neil Jolly, Craig D. Newman, Robert W. Pierce

Patent number: 5741289Abstract: This invention relates to an improved guarded surgical scalpel having a movable guard that can be retracted to expose the blade and that can be extended to cover the sharp cutting edge of the blade. The guard is also mounted for rotatable movement with respect to the handle. A blade carrier is mounted to the guard to allow relative longitudinal movement between the guard and the blade carrier. The blade carrier is also removably mounted to the handle. This mounting arrangement for the handle, guard and blade carrier allows the guard and blade carrier to be rotated away from the handle so the surfaces of the handle, guard and blade carrier can be exposed. This facilitates cleaning of the guarded surgical scalpel after use.Type: GrantFiled: November 25, 1996Date of Patent: April 21, 1998Assignee: Becton, Dickinson and CompanyInventors: Neil Jolly, Craig D.
