Abstract: A device for singulating surgical needles from a bulk supply of needles includes a vibratory bowl for receiving the supply of needles. The bowl has a floor to receive the needles, a track extending from the floor to a needle discharge point and a selectively vibrating motor to vibrate the surgical needles into a single file along the track. A discharge device has first and second needle receiving pockets, and positions the first and the second needle receiving pockets below the needle discharge point. A controller selectively vibrates the vibratory bowl and selectively positions the first and second needle pockets below the needle discharge point, the controller singulating individual needles from the single file of needles into the first and second needle receiving pockets. A discharger discharges the singulated needles in a spaced relationship on a conveyor for subsequent imaging at an inspection station.

Abstract: A method for cuffing suture, including: feeding the suture to a drawing axis for drawing and cutting thereof; heating the suture to stiffen a small length; gripping the suture and alternately drawing it along the drawing axis by first and second grippers; cutting the suture to provide uniform lengths; and providing a predetermined length of suture travel between the heating step and the cutting step, which is a discrete number, two or more, times the uniform length of suture being cut by the apparatus, to provide a discrete number, two or more, of apparatus cutting cycles between heating of the suture and cutting of the suture, whereby after heating of a small length of suture, the suture is cooled to allow setting and hardening of the suture material prior to cutting.

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.

Abstract: A semi-automated machine for preparing double-armed sutures, i.e., a suture with a surgical needle at either end of the suture, from a bulk supply of surgical needles and an indefinite length of suture material is described. Each of the surgical needles has a suture receiving opening formed therein for receiving a suture. The machine includes a needle singulation station, a precise positioning station, a suture feeding and cutting station, a swage station, a pull-test station and an off-load station. A universal gripper mounted on a rotary indexing device automatically receives each individual needle in a predetermined orientation and conveys the needle for sequential processing from station to station to form the needle-suture assembly. A suture drawing and cutting station automatically inserts an end of the indefinite length of suture into the first of the pair of needles that form the double-armed suture.

Abstract: Apparatus for cutting an indefinite length suture to different lengths for subsequent threading and swaging to surgical needles includes a drawing tower having first and second guide members defining a drawing axis parallel thereto. First and second grippers are provided to grip the indefinite length suture and to alternately draw it along the drawing axis, with each gripper being mounted for reciprocal movement along a guide member. Each gripper alternately grips the suture and draws it a distance beyond the location of a cutter assembly while the other gripper reciprocates to a start position before the cutter assembly. A tipping assembly heats a predetermined small length of the suture to stiffen the suture thereat after subsequent cooling, in preparation for cutting the suture thereat and inserting a stiffened lead cut end of the suture into an end of a needle for swaging thereto.

Indexing conveyors, an articulated robot and a precision conveyor are used with a precise positioning station for orienting each needle for automatic handling. A universal gripper mounted on a rotary indexing device automatically receives each individual needle in a predetermined orientation and conveys the needle for sequential processing from station to station to form the needle-suture assembly.

Abstract: Methods and systems for packaging surgical needles. In this system, a plurality of packages are indexed, by means of a package carrier, through a plurality of work stations, at which various operations are performed on the packages. In particular, at each work station, an operating device is moved from a home position to an operating position to perform an operation on the package: and after finishing the operation, the operating device is returned to the home positions. With all of the operating devices in their respective home positions, the package carrier can then be moved to index the packages forward. Each of the work stations generates a respective return home signal when the operating device of the work station returns to its home position.

Abstract: A needle sorting device including an infeed device which first singulates a bulk supply of surgical needles into single file with an intermittently driven vibratory feed bowl assembly, and then individually separates and deposits the needles on a first conveyor for transmission to a processing station with a linear slide discharge mechanism. The first conveyor is translucent and during transit, one or more cameras obtain an image of the individual deposited needles. The image is digitized and the digital signals are transmitted to a control system computer which evaluates the position and orientation for needles and processes the information to obtain data for communication to one or more robot assemblies having grippers. Utilizing the position and orientation data, the robot assembly grippers removes selected needles from the first conveyor and transfers each needle to an engagement device located upon a second precision conveyor.
