摘要： A surgical, tubular-shafted instrument comprises a shaft, an operating rod mounted for displacement in the shaft, a handle part for actuating the operating rod and a connector that detachably connects the handle part to the shaft. The shaft is secured in an axial direction in an inner sleeve of the handle by a locking member that is displaceable radially in the inner sleeve and dips into a recess of the shaft. The radial outward movement of the locking member is limited by a stop element that is displaced into a position releasing the radial outward movement of the locking member. A holding element fixes the stop element in a release position and can be acted upon by the shaft to release the stop element due to displacement of the shaft in the inner sleeve. The holding element is guided for displacement in the handle part outside the inner sleeve.

摘要： A cutting guide for use in spinal surgery includes a sidewall defining an internal cavity. A chisel guide, for use with the cutting guide, includes a first block member to be inserted into the internal cavity of the cutting guide to position the first block member adjacent the vertebral body. The chisel guide also includes a second block member connected to the first block member. An apparatus for creating a cavity in a vertebral body endplate and in an intervertebral disc may be a compressor or a distractor having at least one cutting implement thereon. A tensioner determines a proper elongation distance in a prosthesis implanted in a vertebral body.

摘要： A surgical instrument and method for facilitating the capture of objects during surgery are provided. The surgical instrument comprises a flexible tube having a proximal tube end and a distal tube end, the flexible tube defining a cable passageway and being configured for insertion of at least a distal portion of the flexible tube into a body cavity of a patient. The surgical instrument further comprises a flexible cable having a proximal cable end and a distal cable end. At least a portion of the flexible cable is slidably disposed in the cable passageway. A snare loop having a loop member is attached to the distal cable end. The snare loop and the cable are adapted so that the snare loop can be selectively retracted within the cable passageway by sliding the flexible cable proximally within the cable passageway. The snare loop and the cable are also adapted so that at least a portion of the snare loop can be selectively extended from the distal tube end by sliding the flexible cable distally within the cable passageway. The loop member is adapted for selectively encircling and engaging at least a portion of an object in the body cavity. The system also comprises a steering tether having a proximal tether end and a distal tether end. The distal tether end is attached to the loop member so that application of a tensile force to the proximal tether end causes the snare loop to deform in a predetermined manner, thereby facilitating a maneuvering of the snare loop.

摘要： Surgical scissors include a pair of scissor blades mounted at a distal end of an elongated flexible body and a housing attached to the proximal end of the elongated body. An actuator is coupled with mechanical advantage to the scissor blades for manually controlling shearing movement of the blades in response to finger movement on the actuator back and forth along the housing. Electrical conductors are provided through body and housing from a connector to the scissor blades. The housing is configured to be assembled in mating shells with components assembled in and confined by attached shells that facilitate rapid and accurate fabrication.

摘要： A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated or otherwise activated using the secondary battery as a driving power source to perform surgery on a living tissue. Electromagnetic energy generated by an energy generation unit located outside the surgical instrument is received by a reception coil incorporated in the surgical instrument with the surgical instrument by induction from the energy generation unit. The electromagnetic energy is then converted into charging power with which the secondary battery is recharged. Thus, the surgical instrument can be readily recharged without compromising sterility.

摘要： Disclosed is a single-use surgical scalpel having two molded plastic elements, and a surgical blade. The first molded plastic element is a housing. The housing has an upper and a lower radiused edge, and ribbed interior wall surfaces. The ribbed interior wall surfaces of the molded plastic housing define a channel for slidable engagement of the second molded plastic element which is referred to as a blade carrier. The channel has one open end through which a surgical blade is extended during use, a slot through the lower radiused edge for slidable engagement of an actuator/locking fin, a single-use indicator window, and a retaining element for engaging a distal end of a leaf spring. The molded plastic blade carrier has a first end adapted for engaging the surgical blade, a second end having a leaf spring to assist in blade retraction, the leaf spring having a proximal and a distal end, and a central portion having the actuator/locking fin and a single-use indicator. A single-mold embodiment is also disclosed.
