ABSTRACT:
In a system and method for use in endoscopy and endosurgery, at least one link is pivotally connected between first and second cannulas through which first and second endoscopic devices are inserted into a body part through first and second points of entry in the surface of the body part. Angular movement of the first device about the first point of entry induces angular movement of the second device about the second point of entry. When the first and second devices are respectively an endosurgical instrument and an endoscope, the field of view of the endoscope is caused to track the moving tip of the endosurgical instrument by proper adjustment of the linkage. Thereby, a surgeon may operate an endoscopic surgical instrument while, without conscious effort, the endoscope tracks the instrument tip. According to one embodiment, coupling members are utilized to connect to cannulas of existing design. Each coupling member comprises a structural member provided with means for pivotal coupling and a clasp mechanism rigidly attached to the structural member. Each cannula is inserted through, and thereupon tightly gripped by, the clasp mechanism prior to insertion of the cannula into the body part. Pivotal connections are made between the link member and the structural member. Linkage components of adjustable span and configuration enable effective tracking for endoscopic devices of differing designs. Means are provided to control the degree of insertion of the endoscope into the body part, either by manual operation or by a remotely controlled motor drive. Endoscope cables are supported by a cable support that substantially prevents the weight and drag of the endoscope cables from impeding the surgeon's dexterous use of the linked endosurgical instrument.
