Tissue resecting instrument

A tissue-resecting device, comprising:

• an end effector assembly, including:
• an outer shaft including a hub housing disposed about a proximal end portion thereof;
• an inner shaft disposed within and rotatable relative to the outer shaft, the inner shaft including a distal driver disposed about a proximal end portion thereof;
• a proximal driver slidably coupled to the distal driver in fixed rotational orientation relative thereto such that rotation of the proximal driver drives rotation of the distal driver;
• a retainer cap defining a pocket having an open end, the retainer cap disposed about at least a portion of the proximal driver and fixedly engaged with the hub housing to thereby fix the retainer cap relative to the hub housing and the outer shaft, the retainer cap configured to selectively lock the proximal driver in fixed rotational orientation relative thereto, thereby selectively locking the inner shaft relative to the outer shaft;
• and
• an RFID chip disposed within the pocket, wherein, with the retainer cap engaged with the hub housing, a portion of the hub housing closes the open end of the pocket to retain the RFID chip therein;
• and
• a handpiece assembly, wherein a portion of the end effector assembly is configured for insertion into the handpiece assembly to releasably engage the end effector assembly with the handpiece assembly, thereby operably coupling a motor of the handpiece assembly with the proximal driver of the end effector assembly.

An end effector assembly of a tissue-resecting device, the end effector assembly comprising:

• an outer shaft including a first housing portion disposed about a proximal end portion thereof;
• an inner shaft disposed within and rotatable relative to the outer shaft;
• at least one driver extending through the first housing portion and operably coupled to a proximal end portion of the inner shaft such that rotation of the at least one driver drives rotation of the inner shaft within and relative to the outer shaft, the at least one driver defining a longitudinal axis;
• a second housing portion disposed about at least a portion of the at least one driver and configured to engage the first housing portion to thereby at least partially enclose the at least one driver therein, wherein engagement of the first and second housing portions defines an enclosed pocket therebetween at a location radially spaced from the longitudinal axis;
• an RFID chip disposed within the enclosed pocket;
• and
• an outer shell at least partially surrounding the first housing portion, the outer shell including an engagement finger radially spaced from the longitudinal axis and configured to facilitate engagement of the end effector assembly with a handpiece assembly,
• wherein the engagement finger and the enclosed pocket are disposed in a pre-determined orientation relative to one another such that the RFID chip is oriented in a pre-determined orientation relative to the engagement finger.
