摘要： A surgical system includes a fluid source including a fluid inflow tube, a fluid delivery device coupled to the fluid inflow tube and configured to deliver fluid from the fluid source into a patient, a surgical instrument, and a control box coupled to the surgical instrument. The control box includes one or more waste heat-generating electronic components and a heat pipe assembly disposed in thermal communication with the one or more waste heat-generating electronic components. The fluid inflow tube is disposed in thermal communication with the heat pipe assembly of the control box such that the heat pipe assembly conducts heat away from the one or more waste heat-generating electronic components and heats fluid flowing through the fluid inflow tube.

摘要： An assembly of a surgical instrument includes an outer component of a first material and having an interior surface, an inner component of a second, different material and having an exterior surface, and a bonding agent. The inner component is inserted at least partially into the outer component to define a volume between the interior surface of the outer component and the exterior surface of the inner component. The volume includes a plurality of longitudinal channels extending longitudinally along at least a portion of a length of the volume and a plurality of annular channels extending about at least a portion of a circumference of the volume. The bonding agent at least partially fills each longitudinal channel of the plurality of longitudinal channels and each annular channel of the plurality of annular channels to bond the first component with the second component.

摘要： A tissue resecting instrument includes a drive assembly coupled to an inner cutting shaft and configured to drive translation and/or rotation of the inner cutting shaft, a trigger coupled to the drive assembly and configured for manual actuation to drive the drive assembly, a vacuum generator configured to generate vacuum to suction cut tissue through the inner cutting shaft and into the vacuum generator, and a tissue collection cartridge configured to engage the housing. The tissue collection cartridge defines a port configured to communicate with the vacuum generator such that the vacuum generator urges cut tissue from the vacuum generator through the port into the tissue collection cartridge. The tissue collection cartridge may include at least one histological agent disposed therein, may include a fill indicator configured to indicate a fill level of tissue within the tissue collection cartridge, and/or may include a latch configured to seal the port closed.

摘要： A surgical instrument includes a handpiece including a housing and a motor disposed in the housing. An end effector assembly is operably coupled to the handpiece. The motor actuates the end effector assembly. A temperature measurement assembly is in the housing. The temperature measurement assembly measures a temperature of the motor. The temperature measurement assembly includes a printed circuit board (PCB) including an orifice extending through the PCB. An infrared (IR) sensor is on the PCB. The IR sensor transmits IR light to a temperature measurement location of the motor through the orifice of the PCB. The IR sensor detects IR light reflected from the temperature measurement location of the motor to determine a temperature of the temperature measurement location of the motor.

摘要： A tissue resecting device includes an end effector assembly including a proximal hub housing and a cutting member extending distally from the proximal hub housing, and a handpiece assembly. The handpiece assembly includes a handle housing, a drive casing extending distally from the handle housing, a drive rotor extending through and distally from the drive casing, and a seal ring disposed about the drive rotor. In an at-rest position, the seal ring is sealingly engaged between the drive casing and the drive rotor to inhibit fluid ingress into the annular space. Upon engagement of the end effector assembly with the handpiece assembly, a portion of the proximal hub housing is configured to urge the seal ring from the at-rest position to a displaced position wherein the seal ring is displaced from the drive rotor to reduce friction therebetween upon rotation of the drive rotor relative to the drive casing.
