Abstract
A uterine tissue resection system may include a housing enclosing a power source such as a battery, a motor, and a control board for regulating power to the motor and the battery. Extending distally from the housing may be a cutting assembly comprising an outer cutting tube with an inner cutting tube received therein. The inner cutting tube may be fluidly coupled to an external suction source through a swivel connection interface. The housing may further contain a drive assembly connecting the inner cutting tube to a driveshaft of the motor so that rotation of the driveshaft results in simultaneous rotation and reciprocation of the inner cutting tube.
Claims23
A uterine tissue resection system comprising:
- a housing comprising a handle;
- a power source within the housing;
- a motor within the housing and connected to the power source;
- an outer cutting tube having a first lumen, a closed distal end, and a window through a sidewall thereof leading to the first lumen, the window being located proximal of the closed distal end;
- an inner cutting tube received within the first lumen and having a second lumen extending between an open distal end and an open proximal end, wherein the open proximal end is connected to an external suction source thorough a swivel interface adapted to enable free rotation of the housing relative to the external suction source;
- and
- a drive assembly located within the handle and connecting the inner cutting tube to a driveshaft of the motor such that when the motor receives power from the power source, rotation of the driveshaft causes the inner cutting tube to rotate and reciprocate concurrently.
