摘要:
A surgical dilator extractor is introduced into the abdominal cavity through a trocar cannula and expanded, forming a tissue receiving space, at the distal end. The tissue that is to be extracted is then suctioned to the dilator. The tissue is then removed from the cavity by the surgeon applying a force onto the dilator extractor that insures the elongation of the tissue and temporarily dilates the entry wound to the extent necessary for the tissue to be removed. Alternative embodiments of the surgical dilator extractor and related instrument tool sets and methods for the use thereof also are disclosed.

摘要:
An electric field sensor employs a capacitive pick-up electrode in a voltage divider network connected to a body emanating an electric field. The system is relatively insensitive to variations in the separation gap between electrode and body, reducing sensor motion artifacts in the output signal and stabilizing its low frequency response. The pick-up electrode may be positioned at a “stand off” location, spaced from intimate contact with the surface of the body. This is equivalent to providing low level capacitive values for the capacitive coupling between the pick-up electrode and the body whose electric field is to be monitored. Or a series limiting capacitor may be provided in the input stage. Human body-generated electrical signals may be acquired without use of conductive gels and suction-based electrodes, without direct electrical contact to the body, and even through thin layers of clothing.

An abrasive plate having an abrasive surface for performing abrading applications is provided. The plate includes a base member having a substantially smooth surface with a plurality of holes formed therethrough. A plurality of pairs of spaced apart slots radiate outwardly from each of the holes to define tab members. The tab members may be selectively raised or deformed to protrude from the smooth surface to collectively form an abrasive surface. The number of tabs raised may be selected to control the coarseness of the surface.

An apparatus for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue includes a frame and an elongated endoscopic section connected to the frame and extending distally therefrom. A staple storage cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section. An elongated pusher system is provided for individually advancing at least one staple at a time distally. The pusher system includes a trigger system to actuate the pusher. The trigger system is provided with perceptible tactile sensing means to indicate when the legs of the staple being advanced are exposed so as to be visible to the user for positioning and orientation purposes.
摘要:
An apparatus for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery includes an elongate member defining a longitudinal axis, a cartridge, an anvil, and a control member located in a proximal region of the elongate member. The cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section with each staple being configured and adapted to attach the mesh to the body tissue. The anvil provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to body tissue. The control member is axially movable along the longitudinal axis to articulate the cartridge. The control member is also rotatable to rotate the cartridge.
摘要:
An apparatus is disclosed for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery. The apparatus includes a frame, and a generally elongated endoscopic section connected to the frame and extending distally therefrom. A staple storage cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section with each staple being configured and adapted to attach the mesh to the body tissue. An elongated pusher system formed of several assembled components and extending from the frame to the endoscopic section is provided for individually advancing at least one staple at a time distally for positioning adjacent the surgical mesh and the body tissue. The pusher system also includes a trigger system to actuate the pusher. The trigger system is provided with perceptible tactile sensing means to indicate when the legs of the staple being advanced are exposed so as to be visible to the user for positioning and orientation purposes. Anvil means provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to the body tissue. Projecting distally of the cartridge support system is a pair of legs which are dimensioned and configured to engage the staple during closure to prevent unwanted roll or deformation outside of the plane of the staple.

摘要:
An abrasive plate for use with a power sanding device having an abrasive surface for performing abrading applications. The plate includes at least two rows of protrusions. The protrusions in each row have an orientation substantially the same as the other protrusions in the respective row. The protrusions in each row have a bottom edge portion oriented at an angle of from about 45.degree. to about 135.degree. with respect to the bottom edge portions of the protrusions in each adjacent row. By providing an abrasive plate having protrusions with the above-noted orientations, the forces transmitted through the plate between a surface being treated and a power sander will be substantially balanced.

An elongated pusher system formed of several assembled components and extending from the frame to the endoscopic section is provided for individually advancing at least one staple at a time distally for positioning adjacent the surgical mesh and the body tissue. The pusher system also includes a trigger system to actuate the pusher.

Anvil means provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to the body tissue. Projecting distally of the cartridge support system is a pair of legs which are dimensioned and configured to engage the staple during closure to prevent unwanted roll or deformation outside of the plane of the staple. The staple storage cartridge may be pivoted with respect to the longitudinal axis of the endoscopic section from 0.degree. to about 32.5.degree. and about 65.degree.. Further, the cartridge may be rotated from a proximal location about its own axis independent of the endoscopic section while pivoted to any of the predetermined angles relative to the longitudinal axis of the endoscopic section.
