Abstract

Abstract A stapler device is described which can house a magazine containing surgical staples or clips for closing an open wound. Preferably the magazine will be disposable. The stapler device has two complementally formed jaws which have flanges thereon for enabling such jaws to be connected together so as to be pivotable about a common axis. A set of lever arms are joined at one end thereof to the two jaws, and at the other end to the magazine containing the surgical staples. These lever arms function to convert pivotal movement of the jaws about the common axis to reciprocal and preferably substantially linear movement of the magazine relative to the stapler device. This reciprocal movement of the magazine enables one surgical staple to be advanced at a time preparatory to application to the open wound. Receding of the magazine enables the staple-applying nose portion of the jaws to come substantially together to effect closing of the surgical staple as it is applied to the wound. A scissors-type spring can be provided, if desired, on the jaws to return the same to a neutral rest position, automatically. If this return spring is omitted, two positive squeezing actions are required, one to apply the surgical staple, and the other to open the jaws apart and advance the magazine forwardly to dispense the next surgical staple in readiness for application thereof to the wound. Either way, complete control over the operation of the stapler device remains with the person who is holding such device in his hand.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 200 words
A stapler device adapted to receive and house a magazine for dispensing surgical staples to close an open wound, said device comprising: a first jaw and a second jaw, each jaw having flange means thereon for facilitating joining the same together, the flange means on one of the jaws being positionable within the flange means on the other jaw, with each flange means having an aperture therein for receiving a connecting pin that interconnects said jaws so as to be pivotable about a common axis; a hub element adapted to be housed within the flange means on said jaws, and serving to releasably retain said magazine of staples, the hub element having slot means therein which are in guided engagement with one end of said connecting pin; and a plurality of pivotally interconnected linkages which are rotatably connected at one end thereof to said jaws for actuation by pivotal movement of the latter, with the other end of said linkages being movably connected to said hub element, such that the linkages convert pivotal movement of said jaws to reciprocal movement of the magazine thereby advancing one surgical staple at a time preparatory to application of the same to said wound.
Claim 2
Dependent Claim 200 words
A stapler device adapted to receive and house a magazine for dispensing surgical staples to close an open wound, said device comprising: a first jaw and a second jaw, each jaw having flange means thereon for facilitating joining the same together, the flange means on one of the jaws being positionable within the flange means on the other jaw, with each flange means having an aperture therein for receiving a connecting pin that interconnects said jaws so as to be pivotable about a common axis; a hub element adapted to be housed within the flange means on said jaws, and serving to releasably retain said magazine of staples, the hub element having slot means therein which are in guided engagement with one end of said connecting pin; and a plurality of pivotally interconnected linkages which are rotatably connected at one end thereof to said jaws for actuation by pivotal movement of the latter, with the other end of said linkages being movably connected to said hub element, such that the linkages convert pivotal movement of said jaws to reciprocal movement of the magazine thereby advancing one surgical staple at a time preparatory to application of the same to said wound.
Claim 3
Dependent Claim 32 words
The stapler device of claim 1, wherein spring means are provided on said jaws for returning the same to a normal rest position from either a staple-applying position or a staple-advancing position.
Claim 4
Dependent Claim 283 words
A stapler device adapted to receive and house a magazine for dispensing surgical staples to close an open wound, said device comprising: a first jaw and a second jaw, each jaw having flange means thereon for operatively joining the same together, the flange means on one jaw being receivable within the flange means on the other jaw, with each of the flange means having an aperture therein for receiving a connecting pin such that said first and second jaws are pivotable about a common axis; lever arms mounted on the first and second jaws for operatively connecting said jaws to the magazine of surgical staples, the lever arms being so disposed as to convert pivotal motion of said jaws about the common axis to reciprocal movement of the magazine longitudinally thereof to advance one surgical staple at a time preparatory to application to the wound; and a hub element for guidingly engaging the magazine and being receivable within the flange means on each of the jaws when assembled, the hub element including guide means for engaging said connecting pin to constrain the magazine to said reciprocal movement, with the lever arms having two pairs of pivotally interconnected linkages, one end of each of one of said pairs of linkages being pivotally joined to the jaws for actuation by pivotal movement of said jaws, and one end of each of the other pair of linkageS being connected by a common pivot pin to said hub element, with the other ends of each pair of linkages being pivotally connected to one another by a common pin means, said linkages and the hub element cooperating to produce said reciprocal movement of the magazine of surgical staples.
Claim 5
Dependent Claim 283 words
A stapler device adapted to receive and house a magazine for dispensing surgical staples to close an open wound, said device comprising: a first jaw and a second jaw, each jaw having flange means thereon for operatively joining the same together, the flange means on one jaw being receivable within the flange means on the other jaw, with each of the flange means having an aperture therein for receiving a connecting pin such that said first and second jaws are pivotable about a common axis; lever arms mounted on the first and second jaws for operatively connecting said jaws to the magazine of surgical staples, the lever arms being so disposed as to convert pivotal motion of said jaws about the common axis to reciprocal movement of the magazine longitudinally thereof to advance one surgical staple at a time preparatory to application to the wound; and a hub element for guidingly engaging the magazine and being receivable within the flange means on each of the jaws when assembled, the hub element including guide means for engaging said connecting pin to constrain the magazine to said reciprocal movement, with the lever arms having two pairs of pivotally interconnected linkages, one end of each of one of said pairs of linkages being pivotally joined to the jaws for actuation by pivotal movement of said jaws, and one end of each of the other pair of linkageS being connected by a common pivot pin to said hub element, with the other ends of each pair of linkages being pivotally connected to one another by a common pin means, said linkages and the hub element cooperating to produce said reciprocal movement of the magazine of surgical staples.
