Biopsy forceps having detachable handle and distal jaws

A biopsy forceps device, comprising:

• a hollow member having a proximal end and a distal end, the proximal end having a threaded connecting member rotatably mounted thereon, the threaded connecting member including a first threaded portion, wherein the proximal end of the hollow member further includes at least one barb and the threaded connecting member has at least one ridge, wherein the ridge of the threaded connecting member engages the barb of the hollow member;
• an end effector assembly connected to the distal end of the hollow member;
• an actuator assembly connected to the proximal end of the hollow member for operating the end effector assembly, the actuator assembly including a sliding member slidably mounted on a shaft, the sliding member having a coupling device, the shaft having a second threaded portion for engagement with the first threaded portion of the hollow member;
• and
• a control member slidably disposed within the hollow member, the control member having a distal end connected to the end effector assembly and a proximal end engageable with the coupling device of the sliding member.

A biopsy forceps device, comprising:

• a hollow member having a proximal end and a distal end;
• an end effector connected to the distal end of the hollow member;
• an actuator for operating the end effector, the actuator selectively engageable with the proximal end of the hollow member and including a shaft;
• a control member slidably disposed within the hollow member, the control member having a distal end connected to the end effector and a proximal end;
• and
• a sliding member slidably mounted on the shaft of the actuator, the sliding member including a spring-loaded coupling device configured to selectively engage the proximal end of the control member to selectively couple the control member to the sliding member.

A distal biopsy forceps assembly for connection with an actuator, the actuator including a shaft having a first mating portion and a sliding member having a coupling device, the assembly comprising:

• a hollow member having a proximal end and a distal end;
• a connecting member rotatably mounted on the proximal end of the hollow member and having a second mating portion for selectively engaging the first mating portion;
• an end effector assembly connected to the distal end of the hollow member;
• and
• a control member slidably disposed within the hollow member, the control member having a distal end connected to the end effector assembly and a proximal end engageable with the coupling device of the sliding member, wherein the distal biopsy forceps assembly may connect to the actuator by engagement of the second mating portion with the first mating portion and engagement of the proximal end of the control member with the coupling device of the sliding member.

A distal biopsy forceps assembly for connection with an actuator, the actuator including a shaft having a first threaded portion and a sliding member having a coupling device, the assembly comprising:

• a hollow member having a proximal end and a distal end, the proximal end rotatably mounting a connecting member having a second threaded portion engageable with the first threaded portion, wherein the proximal end of the hollow member further includes at least one barb and the threaded connecting member has at least one ridge, wherein the ridge of the threaded connecting member engages the barb of the hollow member;
• an end effector assembly connected to the distal end of the hollow member;
• and
• a control member slidably disposed within the hollow member, the control member having a distal end connected to the end effector assembly and a proximal end engageable with the coupling device of the sliding member, wherein the distal biopsy forceps assembly may connect to the actuator by engagement of the second mating portion with the first mating portion and engagement of the proximal end of the control member with the coupling device of the sliding member.
