A novel, monopolar, electrosurgical instrument is provided with one active and one non-active end effector. Current is passed through a conductive portion of one effector into tissue of a patient. The active blade may be partially or totally conductive. The non-active blade may be utilized to shield current from the active electrode effector.

The present invention relates to a clamping device for insertion through a working channel of an endoscope. The clamping device comprises an elongated housing body having a thumb ring on a first end thereof and a flexible elongated outer sheath attached to a second end of the housing. An inner sheath is slidably arranged within the housing and the outer sheath. A biasable clamp arrangement is connectively disposed on the distal end of the inner sheath. An annular ring is arranged on the distal end of the outer sheath. The biasable clamp arrangement is openable and closable in response to longitudinal movement of the inner sheath with respect to the outer sheath by a camming action between the arms and the annular ring. The arms may be connected to a proper circuit for providing mono-polar or bi-polar energization to tissue clamped between the arms comprising the clamp arrangement.

A method and apparatus for ligating tissue is disclosed. The applicator utilizes a jaw portion having jaw members with jaw faces to grasp tissue and operating portions to apply a surgical clip. In a presently preferred embodiment, the surgical clip utilized is a self-closing clip. Operating faces in the operating portion of the jaw members separate the clip from the tissue prior to clip installation. The applicator has a channel in the operating portion for user viewing which also may allow for lateral displacement of a clip external to the jaw faces.

A trocar is formed from a cannula and an interfitting obturator for penetrating body cavity walls in laparoscopic and endoscopic surgery. The cannula has an improved inexpensive flexible flapper valve and can be manufactured with a reusable cannula tube but disposable flapper valve assembly to minimize cost.

A novel, bipolar, electrosurgical instrument is provided with one metal and one ceramic end effector. Current is passed through the metal end effector and through an insulated conduit to the distal tip of the ceramic end effector. A connection at the distal tip of the ceramic end effector allows the current to return along exposed conductive strip which is spaced apart from the metal end effector in cutting action by a gap of approximately 0. 020 inches when the ceramic and metal blade supports are brought into contact with tissue, a current flows from the exposed metal strip on the ceramic blade through to the metal blade thereby effecting cauterization, preferably slightly in advance or at the point of cutting between the ceramic and metal blades.

A trocar is formed from a cannula and an interfitting obturator for penetrating body cavity walls in laparoscopic and endoscopic surgery. The obturator is provided with an improved piercing tip having a pointed blade with an improved sheath mounting and shield design. Hydrophilic coatings or components are also employed on the shield and cannula to facilitate quicker shield action covering the pointed blade and ease of entry of the cannula tube through the body cavity wall. The sheath and obturator handle and housing assembly may be fabricated as a single plastic piece.

A novel reducer system is provided for a trocar cannula. The reducer system fastens to the cannula end and a living hinge allows a reducer cap to be closed over the cannula lumen to allow the cannula to be used with smaller diameter surgical instruments. By fastening the reducer system to the exterior of the cannula end, the system can be placed in position on the cannula prior to surgery, even while a large diameter obturator is used with the cannula.

A trocar is formed from a cannula and an interfitting obturator for penetrating body cavity walls in laparoscopic and endoscopic surgery. The obturator is provided with an improved piercing tip having a pointed blade and an improved double locking blunt nosed shield design. Hydrophilic coatings or components are also employed on the shield and cannula to facilitate quicker shield action covering the pointed blade and ease of entry of the cannula tube through the body cavity wall. The cannula also has an improved inexpensive flexible flapper valve and can be manufactured with a reusable cannula tube but disposable flapper valve assembly to minimize cost.
