Abstract
Abstract An improved laparoscopic technique for treating female urinary incontinence and devices for use therein. These devices include an urethral sound, a stapling device, and a staple saw. The sound is substantially L-shaped having a handle at one end and a probe tip at the opposite end. The probe tip has a plurality of beads protruding therefrom which are observable through the wail of the bladder enabling the junction between the lower border of the bladder and urethra to be located. The stapling device attaches the pelvic floor to the pubic bone. The stapling device comprises of a handle, a stapling head, and an elongated member extending therebetween. The stapling head is pivotally attached to the elongated member. A push rod advances a pair of target pins to anchor the pelvic floor to the pubic bone. A small trigger loads staples into a discharge chamber. A large trigger discharges staples from the stapling head into the pelvic floor and pubic bone. The travel of the staple is limited by a stop plate which prevents the staple from being driven through the pelvic floor. In the event the staple is incorrectly discharged, the staple saw is provided for severing the staples and prying the severed staples apart releasing the pelvic floor therefrom. The staple saw is comprised of a handle, a hook for grappling the staple, and an elongated member extending therebetween. A trigger advances a saw blade. A crank manually drives the saw blade.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
185 words
A surgical stapling device for stapling a pelvic floor to a pubic bone when treating female urinary incontinence, said stapling device comprising: a) a stapling head including: 1) a pair of target pins for anchoring said stapling head and the pelvic floor to the pubic bone, 2) a discharge chamber for receiving a staple to be discharged from said stapling head, 3) a staple discharge mechanism for discharging a staple from said stapling head into said pelvic floor and further into said pubic bone; b) a handle including: 1) a push rod extending through said handle for advancing said target pins forward so as to extend said target pins from said stapling head, 2) a first, small trigger means extending from said handle for actuating a staple loading mechanism, and 3) a second, large trigger means extending from said handle for actuating said staple discharge mechanism; and c) an elongated member extending from said stapling head to said handle, said elongated member providing passage for said push rod and including: an actuation rod for connecting said second, large trigger means to said staple discharging mechanism.
Claim 2
Dependent Claim
185 words
A surgical stapling device for stapling a pelvic floor to a pubic bone when treating female urinary incontinence, said stapling device comprising: a) a stapling head including: 1) a pair of target pins for anchoring said stapling head and the pelvic floor to the pubic bone, 2) a discharge chamber for receiving a staple to be discharged from said stapling head, 3) a staple discharge mechanism for discharging a staple from said stapling head into said pelvic floor and further into said pubic bone; b) a handle including: 1) a push rod extending through said handle for advancing said target pins forward so as to extend said target pins from said stapling head, 2) a first, small trigger means extending from said handle for actuating a staple loading mechanism, and 3) a second, large trigger means extending from said handle for actuating said staple discharge mechanism; and c) an elongated member extending from said stapling head to said handle, said elongated member providing passage for said push rod and including: an actuation rod for connecting said second, large trigger means to said staple discharging mechanism.
Claim 3
Dependent Claim
30 words
The stapling device according to claim 1, wherein said stapling head has a length of 3 to 4 cm to accommodate the movement of said staple discharge mechanism contained therein.
Claim 4
Dependent Claim
101 words
The stapling device according to claim 2, further comprising an aperture in said handle and means defining a plurality of notches in and along a bottom surface of said push rod, and wherein said push rod extends from said aperture in said handle, there further being a tooth disposed adjacent said aperture, said aperture being cooperatively engagable with one of a plurality of notches disposed along a bottom surface of said push rod to enable said push rod to be selectively locked into a desired position corresponding to a desired length of extension of said target pins from said stapling head.
Claim 5
Dependent Claim
29 words
The stapling device according to claim 1, wherein said elongate member has a diameter ranging from 10 to 11 mm to yield to an inside diameter of a trocar.
Claim 6
Dependent Claim
40 words
The stapling device according to claim 1, further comprising a push plate, said push rod being joined perpendicularly to one side of said push plate, an opposite side of said push plate having extending therefrom said pair of target pins.
Claim 7
Dependent Claim
40 words
The stapling device according to claim 1, further including means defining a pair of elongated bores situated on opposed sides of said stapling head, for receiving said target pins therethrough and for providing rigid radial support for said target pins.
Claim 8
Dependent Claim
77 words
The stapling device according to claim 1, further comprising a pair of coil springs, a compression plate, and a drive plate, and wherein said second, large trigger advances said actuation rod to compress said pair of coil springs, each of said coil springs being equal in length and being positioned between said compression plate and said drive plate, said coil springs each being compressible to a predetermined extent necessary to drive a staple into the pubic bone.
Claim 9
Dependent Claim
71 words
The stapling device according to claim 7, further including a leverage plate and a retainer plate, and wherein, as said actuation rod advances, said actuation rod engages said leverage plate to leverage said retainer plate to release a staple from a detained position, whereby, when a staple is released from said detained position, a staple is driven by said coil springs into the pubic bone, thus anchoring the pelvic floor thereto.
Claim 10
Dependent Claim
30 words
The stapling device according to claim 7, further including means defining a lower cavity for enabling said retainer plate to pivot downwardly to release a staple from a detained position.
Claim 11
Dependent Claim
