Title: Apparatus for attaching surgical suture components
Inventor: PROTO GEORGE R
IPC: B21D39/04
Filed: 1990-09-28
Abstract: ABSTRACT A pair of dies is disclosed for attaching a surgical needle having a generally cylindrical end portion defining an elongated aperture having a generally circular cross-section and a suture having a generally elongated end portion of generally circular cross-section corresponding in dimension to the elongated aperture of the first needle. Each die has a pair of extensions spaced apart from each other and defines a generally circular crimping surface portion corresponding in dimension and configuration to the generally cylindrical outer surface portion of the needle. The space defines a unique relief zone between the pair of extensions of the die and is of configuration and dimension sufficient such that when the ssuture is positioned within the aperture of the needle and the dies are respectively positioned about the corresponding portion of the needle, the application of impact force to the dies will cause crimping of the needle with respect to the suture so as to attach the suture and the needle while portions of material forming part of the needle adjacent the stricken area are permitted to be deformed and to collect within the relief zones defined between the pairs of arcuate surface portions. Generally arcuate die overlap portions may be optionally provided on each die.  A method of attaching a surgical needle to a suture is also disclosed.

Inventor: ASAIDA TAKASHI
IPC: H04N9/04
Filed: 1990-10-03
Abstract: A signal processing circuit for a solid-state imaging apparatus in which an imaging output signal from each solid-state image sensor of an imaging section making use of spatial offsetting is digitized to form a detail signal for image enhancement by digital signal processing. A first delay circuit having at least one delay unit with a delay time approximately equal to one horizontal scanning period provides the above mentioned delay time to a green color imaging signal of the digital output signal obtained by digitizing image output signals read from the solid-state image sensors. The signal synthesis is then performed in a first synthesis circuit to limit the band of the green color imaging signal in the perpendicular imaging signal. A second delay circuit having at least one digital delay unit having a delay time about equal to one horizontal scanning period provides the above mentioned delay time to one of the red or blue color imaging signals or combined red and blue color imaging signals of the above mentioned digital output signal. Signal synthesis is then performed by a second synthesis unit to limit the band of the red or blue color imaging signal or the combined red and blue color imaging signals in the perpendicular direction. Equal amounts of the first and second synthesis signals are summed together in a summation unit so as to be outputted as the horizontal detail signal via digital filer unit.
