Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

Systems and methods for tissue removal

An electrosurgical instrument includes jaws having an electrode configuration utilized to electrically modify tissue in contact with one or more electrodes. The instrument is removably connectable to an electrosurgical unit via an electrosurgical connector extending from the instrument and a receptacle on the electrosurgical unit. The electrosurgical instrument is rotatable without disrupting electrical connection to the electrodes of the jaws. One or more of the electrodes is retractable. The electrosurgical unit and instrument optimally seals and/or cuts tissue based on identifying the tissue and monitoring the modification of the tissue by the application of radio frequency energy.

Electrosurgical instruments and connections thereto

A bipolar electrosurgical fusion/sealer and dissector is provided that is arranged to simultaneously fuse and cut tissue captured between jaws of the instrument. The jaws include particularly positioned, shaped and/or oriented electrodes along with a compressible landing pad to perform the simultaneous fusion and cutting of tissue. An electrosurgical generator is arranged to supply RF energy through the instrument and monitors a phase angle of the supplied RF energy and adjusts or terminates the supplied RF energy based on the monitored phase angle to optimally fuse and dissect the tissue.

Electrosurgical seal and dissection systems

An electrosurgical system is provided and includes a bipolar electrosurgical instrument and an electrosurgical generator. The bipolar electrosurgical instrument is arranged to seal and cut tissue captured between jaws of the instrument. The jaws include particularly positioned, shaped and/or oriented electrodes to perform the sealing of tissue. The electrosurgical generator is arranged to supply RF energy through the instrument, monitor the supplied RF energy and adjust or terminate the supplied RF energy to optimally seal the tissue.

Electrosurgical system

An electrosurgical generator arranged to supply radio frequency (RF) energy to fuse tissue is provided. The generator is arranged to supply RF energy through a removably coupled electrosurgical instrument to fuse tissue grasped by the instrument. The generator monitors a phase angle of the supplied RF energy and adjusts or terminates the supplied RF energy based on the monitored phase angle in comparison to predetermined thresholds and conditions to optimally fuse the tissue. The electrosurgical instrument conducts radio frequency energy to fuse tissue captured between the jaws and a blade to mechanically cut tissue between the jaws. A conductive post positioned on the jaw adjacent to the blade.

A laparoscopic clip applier can have a geared clip feed mechanism and a direct jaw clamping mechanism to provide smooth operation over a clip application stroke of a movable handle. The geared clip feed mechanism can include an idler gear and two drive gear racks to advance a feed slider feeding a clip to a jaw assembly. The two drive gear racks can be positioned to provide different gearing during clip feed and firing portions of the clip application stroke, allowing efficient packaging of the clip feed mechanism. A spring can rapidly withdraw the feed slider once the clip has been fed and before clamping begins. The movable handle can have a direct connection to a clamping slider to enhance user feedback during clamping of the clip. After clamping the clip, the movable handle can also assist in returning the clamping slider to an initial position for firing another clip.
