Multifunctional instrument with interchangeable operating units for performing endoscopic procedures
First Claim
1. An endoscopic instrument comprisinga housing;
- an outer tubular member having a proximal end mounted by said housing and terminating distally at a distal end;
an intermediate member having a tubular body disposed telescopically within said outer tubular member, a proximal end mounted by said housing and an integral one-piece distal end defining a pair of opposed jaws resiliently biased apart;
an inner member removably disposed at least partly within said intermediate member and carrying an operating member; and
handle means coupled with at least one of said intermediate and outer tubular members for creating relative movement between said intermediate and outer tubular members, whereby said pair of opposed jaws is closed when said distal end of said outer tubular member is advanced distally over said jaws.

Abstract
An endoscopic instrument includes a forceps unit for being positioned within an anatomical cavity and a removable operating unit. The forceps unit includes a housing, an outer tubular member, an intermediate member, and a handle mechanism coupled with at least one of the intermediate and outer tubular members for creating relative movement between the intermediate and outer tubular members. The outer tubular member has a proximal end mounted by the housing and terminates distally at a distal end. The intermediate member has a tubular body disposed telescopically within the outer tubular member, a proximal end mounted by the housing and an integral one-piece distal end defining a pair of opposed jaws resiliently biased apart such that relative movement of the outer tubular member distal end over the jaws causes the jaws to close. The operating unit includes a hub mounting an inner tubular member removably disposed at least partly within the intermediate member and carrying operating members for performing at least one of the functions of cutting, grasping, manipulating, dissecting, collecting tissue for biopsy, penetrating tissue with a needle, injecting fluids, creating suction, aspirating, irrigating, suturing, ligating, visualizing, illuminating and cauterizing.

52. An endoscopic instrument comprising
a housing; -
an outer tubular member having a proximal end mounted by said housing and terminating distally at a distal end; an intermediate member having a tubular body disposed telescopically within said outer tubular member, a proximal end mounted by said housing and an integral one-piece distal end defining a pair of opposed jaws resiliently biased apart, said intermediate member defining a lumen in communication with an opening in said housing; bias means for biasing said outer tubular member over said jaws; and handle means coupled with at least one of said intermediate and outer tubular members for creating relative movement between said intermediate and outer tubular members, whereby said pair of opposed jaws can be opened when said distal end of said outer tubular member is retracted proximally relative to said jaws.

53. A method of performing endoscopic procedures comprising the steps of
introducing a tubular member with integrally formed jaws through an opening in an anatomical cavity wall; -
grasping anatomical tissue with the jaws; advancing an inner member distally through the tubular member; and performing a medical procedure with the inner member. - View Dependent Claims (54, 55, 56)

57. A method of performing endoscopic procedures comprising the steps of
introducing a tubular member with integrally formed jaws through an opening in an anatomical cavity wall; -
advancing an inner member carrying an operating member distally through the tubular member until the operating member protrudes distally from the jaws; and performing a medical procedure with the operating member. - View Dependent Claims (58, 59, 60, 61, 62, 63)

64. A method of performing endoscopic procedures comprising the steps of
introducing a tubular member with integrally formed jaws through an opening in an anatomical cavity wall; -
advancing an inner member distally through the tubular member until an operating member carried by the inner member is disposed between the jaws, said operating member having opposed distal portions biased apart; opening the jaws to permit the opposed distal portions of the operating member to separate; positioning anatomical tissue between the opposed distal portions of the operating member; and closing the jaws to move the opposed distal portions of the operating member toward one another. - View Dependent Claims (65, 66)
