Apparatus and methods of effecting a medical procedure, e.g., laparoscopic, endoscopic, etc. procedures, through a small percutaneous incision or puncture in the body of a patient. One embodiment of the apparatus comprises an elongated outer tube, an elongated inner tube located within the outer tube and moveable relative thereto. An electrosurge electrode is mounted on the distal end of the inner tube so that it can be moved to a retracted position when it is not need or to an extended position when it is to be use. A vacuum system and an irrigation system are provided. The vacuum system is arranged to apply suction through an annular space between the tubes to effect the removal of tissue or other debris from the operative site within the patients body. The irrigation system is arranged to supply an irrigation liquid through the inner tube to the operative site. Each of the tubes is formed of an electrically insulating material so that the apparatus can be safely inserted within the patient's body. Various types of electrodes can be used. In another embodiment the electrode tip is not retractable.

Electrosurgical apparatus for laparoscopic procedures and method of use

The present invention provides an improved trocar assembly for use in creating an incision in a patient. The trocar of the present invention includes a unique piercing apex, which eases the insertion process, and an internal tip protector to protect the patient and medical personnel from accidental puncture injuries. The improved tip protector is designed to become fully extended immediately after the leading edge of the trocar enters the patient, thus avoiding many of the operational drawbacks of existing trocar tip protector designs. Additionally, the present invention provides an improved tip protector locking mechanism which is believed to be far simpler and more reliable than existing locking mechanisms.

Trocar and cannula assembly

A merchandise display hook for apertured panelboard displays, preferably of all-plastic construction for manufacture by injection molding, is provided with an optionally useable locking key which is installed after mounting of the display hook, to prevent accidental removal thereof. The base of the display hook is formed with a rearwardly opening guide channel arrangement which provides for the reception and guidance of front and back guide legs for the locking key, by means of which the key is installed on and secured to the display hook. Provision is made for removal of the key, when necessary, by insertion of a small tool.
