US 6,314,705 B1 · Operating procedures for automated needle sorting, swaging and packaging machines

Abstract

A machine, and operating procedures for a machine, for automatically threading, swaging and packaging surgical needles. A first mechanism is used to suture the needles and to pull test the needles to determine if certain maximum and minimum pull test requirements are met. The sutured needles are then transferred to packages on a second mechanism, and that mechanism indexes the packages through a series of stations to complete the packaging of the needles. Various checks are made at the packaging mechanism before that mechanism is operated to index the needle packages; and different items at the station used to pull test the needles, are monitored to determine if they return timely to predetermined positions. Also, check are made at the station at which the needles are transferred to the packages, to be sure that those items are in preferred positions before the packages are moved. A detector unit and procedure are employed to inspect the packages for sutures hanging outside the packages, and another detector unit and procedure are provided to inspect the packages for needles protruding from the packages.

Dependent claims

A packaging method for packaging a plurality of surgical needles and sutures in a single package wherein the package is on a movable carrier, said method comprising the steps of:

placing a plurality of needles in a package, each of the needles having a suture connected to the needle;
gathering the sutures in a predetermined area of the package;
inspecting for a suture extending outside said predetermined area;
generating a signal if one of the sutures is found extending outside the predetermined area;
further comprising moving the carrier to move the package to a predetermined location;
wherein moving the carrier includes the step of activating a motor to move the carrier, and deactivating the motor when the package is in the predetermined location;
and
the inspecting step includes the step of inspecting for a suture extending outside said predetermined area when the packages is at the predetermined location;
the inspecting step further includes the step of
i) repeatedly checking to determine whether the motor is activated or deactivated, and
ii) initiating a routine for inspecting for a suture outside the predetermined area, when the motor is determined to be deactivated.
