    • 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. This second precision conveyor is provided with additional devices to further orient the needle transferred thereto. A moveable hard stop is provided at the end of the precision conveyor to provide precise positioning of the needle to an accuracy of 0.001 inch at needle hand-off. Each oriented and precisely positioned needle is conveyed by the second conveyor to an automatic swaging station where sutures are automatically attached.
    • 一种针分选装置,其包括进料装置,该进料装置首先用间歇驱动的振动进料碗组件将大量供应的外科手术针整形成单个文件,然后在第一输送机上单独地分离和沉积针,以便传送到具有线性 滑动排​​放机构。 第一输送机是半透明的,并且在运输过程中,一个或多个照相机获得单个沉积针的图像。 图像被数字化,并且数字信号被传送到控制系统计算机,该控制系统计算机评估针的位置和方向,并处理信息以获得用于与具有夹持器的一个或多个机器人组件通信的数据。 利用位置和方向数据,机器人组件夹具从第一传送器移除所选择的针,并将每个针转移到位于第二精密输送机上的接合装置。 该第二精密输送机设置有另外的装置,以进一步定向转移到其上的针。 在精密输送机的末端提供可移动的硬止动器,以在针切换时精确定位针头0.001英寸。 每个定向和精确定位的针由第二传送器输送到自动模锻台,其中缝线自动附接。

    • A device for singulating surgical needles from a bulk supply of needles including a vibratory bowl assembly for receiving said bulk supply of needles. The bowl assembly having 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 having first and second needle receiving pockets, the device positioning the first and the second needle receiving pockets below said needle discharge point; a controller for selectively vibrating the vibratory bowl and selectively positioning 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 for discharging the singulated needles in the first and second needle pockets in a spaced relationship on a conveyor for subsequent imaging at an inspection station.

    • 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. A swage station is provided for swaging the needle to close the suture receiving opening about the suture to secure said suture thereto. The suture drawing and cutting station then cuts the indefinite length, and inverts the cut end for insertion into the second of the pair of needles. The swage station then swages the second needle to close the suture receiving opening about the suture to secure said suture thereto and thereby form the double-armed suture.
