Apparatus for applying wound treatment material using tissue-penetrating needles
First Claim
1. A surgical apparatus, comprising:
- a first half-section having a distal end and a proximal end, the first half-section being adapted to receive a disposable loading unit in the distal end thereof;
a second half-section in juxtaposed relation to the first half-section, the second half-section having a distal end and a proximal end;
a disposable loading unit selectively operatively engagable with the distal end of the first half-section, the disposable loading unit including;
a cartridge;
a plurality of deployable needles supported within the cartridge, wherein each needle includes a lumen extending therethrough, and at least one hole formed in an outer periphery thereof for radially dispensing a fluid;
a needle pusher in operative association with each needle for sequentially deploying each needle from the cartridge and into a target tissue; and
an actuation member translatably disposed within the cartridge for delivering a driving force to each needle pusher to deploy the needles from the cartridge; and
a wound treatment material applicator assembly for delivering a wound treatment material to the target surgical site, the applicator assembly including;
a respective reservoir supported on an outer periphery of the distal end of each of the first and second half-sections, wherein the wound treatment material is disposed within each reservoir and at least one of the reservoirs is in direct fluid communication with the plurality of deployable needles.

Abstract
A surgical apparatus is provided including a disposable loading unit selectively operatively engagable within a distal end of a first half-section; and a wound treatment material applicator assembly for delivering wound treatment material to the target surgical site. The disposable loading unit includes a cartridge; a plurality of deployable needles supported within the cartridge, wherein each needle includes a lumen extending therethrough and at least one hole formed in an outer periphery thereof; and an actuation member translatably disposed within the cartridge for delivering a driving force to each needle to deploy the needles from the cartridge. The applicator assembly includes a first and second reservoir supported on the distal end of a respective first and second half-section; and a source of wound treatment material in fluid communication with each reservoir.

15. A method of operating on tissue at a target surgical site, comprising the steps of:
-
providing a surgical apparatus including; a disposable loading unit selectively operatively supportable in a distal end of a first half-section, the disposable loading unit having a cartridge operatively supporting a plurality of deployable needles, wherein each needle includes a lumen extending therethrough and at least one hole formed in an outer periphery thereof, and an actuation member translatably disposed within the cartridge for delivering a driving force to each needle to sequentially deploy the needles from the cartridge; and a wound treatment material applicator assembly for delivering wound treatment material to the target surgical site, the applicator assembly having at least one reservoir supported on a distal end of each of a first and a second half-section, and a wound treatment material disposed within each reservoir; clamping adjacent layers of tissue between a distal end of a first and a second half-section of the surgical apparatus; and firing the surgical apparatus, wherein firing of the surgical apparatus includes distally advancing the actuation member to sequentially drive the plurality of needles through the clamped tissue, and dispensing the wound treatment material to the clamped tissue from each reservoir, through the plurality of needles. - View Dependent Claims (16, 17, 18, 19, 20, 21, 25, 26)
