摘要：
abstract an apparatus for endosurgical use includes an instrument having an end effector and a staple cartridge insertable into the end effector. The staple cartridge includes staples, staple apertures, a resistive member, and a medical fluid. when coupled to a power source, the medical fluid is vaporized by the resistive member and expelled out of the staple apertures into the stapled tissue. the power source may be contained within the instrument. in one configuration, a resistive strip with strip contacts may electrically couple to a conductor in the end effector. the medical fluid may also be divided into a plurality of sealant pads corresponding to the staple apertures, and the medical fluid may be a depolymerizable cyanoacrylate, a sprayable thermoplastic urethane, or any vaporizable medicament or pharmaceutical. The staple drivers may include one or more apertures to allow the medical fluid to pass through or around the staple drivers. 2324772 ************************************************* ******** Summary of the Summary Patent Brief: "Cartridge of heated and resistive surgical clamps with phase change seal". The present invention relates to an apparatus for endosurgical use which includes an instrument having an end actuator and a staple cartridge insertable into the end actuator. the staple cartridge includes staples, staple openings, a resistive member and a medical fluid. when coupled to a power source, medical fluid is vaporized by the resistive member and expelled from the clip openings onto the stapled tissue. The power source may be contained within the instrument. In one embodiment, a resistive strip with strip contacts may electrically couple to a conductor on the end actuator. The medical fluid may also be divided into a plurality of sealing blocks corresponding to the clip openings, and the medical fluid may be a depolymerizable cyanoacrylate, a sprayable thermoplastic urethane or any vaporizable medicament or pharmaceutical product. clip guide
