Abstract
A ring applicator device and method for applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder slidably disposed within an outer cylinder, forceps means slidably disposed within said inner cylinder, and means for moving said forceps means into and out of the inner cylinder and for ejecting an elastic ring from the end of said inner cylinder by displacing said outer and inner cylinders relative to each other. The ring applicator device and method is particularly effective in withdrawing a reproductive tubular member inside of the inner cylinder, thereby forming a loop therein, and displacing the inner cylinder relative to the outer cylinder to eject the elastic ring around said loop, in a one-step operation.

A ring applicator device for use in applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder and an outer cylinder, said inner cylinder being slidably disposed within said outer cylinder, forceps means slidably disposed within said inner cylinder and operating slide means operatively associated with the forceps means and the inner and outer cylinders for distally displacing the forceps means relative to the inner cylinder and the forceps means and the inner cylinder relative to the outer cylinder as the result of a single continuous movement of said operating slide means toward the distal end of the ring applicator.
A ring applicator device for use in applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder provided with a first operating slot and an outer cylinder provided with a second operating slot which is longer than said first operating slot, said inner cylinder being slidably disposed within said outer cylinder, forceps means slidably disposed within said inner cylinder, said forceps means containing a shaft portion which has an engageable end portion, and an operating slide means disposed on said outer cylinder, said operating slide means provided with connecting means which extends from the operating slide, through said first and second operating slots and into engaging relationship with said engageable end portion.
A ring applicator device for use in applying an elastic occluding ring to an anatomical tubular structure which comprises a cylinder-type element, the proximal end portion of said cylinder-type element being adapted to receive said elastic occluding ring, forceps means associated with said cylinder-type element and operative to grasp the anatomical tubular structure and draw it inside said cylinder-type element to form a bend therein, a ring pushing means movably and operatively associated with said cylinder-type element for displacing the elastic occluding ring from said cylinder-like element to a position around said bend, thereby forming a closed loop in said anatomical tubular structure and operating slide means operatively associated with the cylinder-like element, the forceps means and the ring pushing means for effecting relative movement therebetween, whereby both the forceps means and the cylinder-like element are distally displaced relative to the ring pushing means as a result of a single continuous movement of said operating slide means in the distal direction and thereafter the forceps means is displaced in the proximal direction to release the occluded anatomical tubular structure from the ring applicator device.
In a surgical ligating instrument for tubal ligation within the human and/or animal body by the application of at least one elastic ring to an anatomical tube, the combination which comprises:
- (a) an elongated inner member having a forward end and a rearward end and having a grasping means at its forward end constructed and arranged for grasping the anatomical tube to be ligated,
- (b) tube means adapted to fit slidably over said member (a) with close sliding fit therebetween,
- (c) said tube means (b) having a surface adjacent its forward end over which an elastic ring is adapted to fit in a tensioned condition,
- (d) manually engageable actuating means operatively connected to said member (a) to slide it rearwardly within said tube means (b),
- (e) means operative upon retraction of said member (a) relative to tube means (b) to actuate said grasping means to grasp the anatomical tube to be ligated and to draw it rearwardly into tube means (b),
- (f) ejecting means operative upon further retraction of said member (a) concurrently with said tube means (b) to eject said elastic ring from the surface of tube means (b) while said anatomical tube to be ligated extends into said tube means (b), thereby releasing said tensioned ring into a position surrounding said anatomical tube and effecting tubal ligation, and,
- (g), means for detecting said further retraction of said member (a) comprising a resistance means operatively associated with said manually engageable actuating means (d) for imposing thereon a manually detectable progressively increasing resistance to said further retraction of said member (a) relative to said tube means (b) prior to the ejection of the elastic ring.
In a surgical ligating instrument for tubal ligation within the body by the application of at least one elastic ring, the combination which comprises:
- (a) a straight, elongated rod having forceps means at its forward end and having a rearward end spaced from said forward end,
- (b) a straight, elongated inner tube closely slidably fitted over said rod (a),
- (c) a straight, elongated outer tube closely slidably fitted over said inner tube (b),
- (d) yieldable means providing an progressively increasing yielding resistance connecting outer tube (c) to inner tube (b) with the forward end of inner tube (b) projecting forwardly beyond the forward end of outer tube (c), and (e) manually operable means connected to said rod (a) for moving said rod (a) independently of said inner tube (b) without encountering said yielding resistance, said manually operable means (e) also connected to said tube (b) to retract said tube (b) and rod (a) against said yielding resistance after said independent movement of rod (a), but prior to the ejection of said elastic ring.
In a surgical ligating instrument for tubal ligation within the body by the application of at least one elastic ring to an anatomical tube, the combination which comprises:
- (a) a straight, elongated rod having grasping means at its forward end and having a rearward end spaced from said forward end,
- (b) a straight, elongated inner tube closely slidably fitted over said rod (a) and having a surface adjacent its forward end over which an elastic ring is adapted to fit in a tensioned condition,
- (c) a straight, elongated outer tube closely slidably fitted over said inner tube (b),
- (d) manually engagable actuating means operatively connected to said rod (a) to slide it rearwardly within said inner tube (b) and thus actuate such grasping means to grasp the anatomical tube to be ligated and to draw it rearwardly into said inner tube (b),
- (e) means to stop the rearward movement of rod (a) in inner tube (b) when the grasped anatomical tube has been retracted into the forward end of the inner tube (b) and to provide for the further retraction thereafter of rod (a) and inner tube (b) in fixed relationship to each other within outer tube (c),
- (f) spring means at the rearward end of inner tube (b) adapted to impose a manually detectable progressively increasing resistance upon said further retraction of said rod (a) and inner tube (b) relative to said outer tube (c) and prior to the ejection of said elastic ring, and
- (g) ejecting means operative upon said further retraction to eject said elastic ring from the surface of said tube (b) while said anatomical tube to be ligated extends into said tube (b), thereby releasing said tensioned ring into a position surrounding said anatomical tube and effecting tubal ligation.
In a surgical ligating instrument for tubal ligation within the body by the application of at least one elastic ring, the combination which comprises:
- (a) a straight, elongated rod having forceps means at its forward end and having a rearward end spaced from said forward end,
