BIOPSY TRACT SEALANT APPLICATOR DEVICE AND BIOPSY SYSTEM

摘要

A biopsy tract sealant applicator device includes a housing and a syringe having a body that is configured to move in an interior chamber of the housing between an extended position and a retracted position. The body is configured for connection to a biopsy cannula. A plunger of the syringe has a piston configured to move in a cylinder of the syringe between a proximal position and a distal position. The spring unit is coupled to the body of the syringe and to the housing. A gear train is operatively coupled to each of the housing, the body of the syringe, and the plunger of the syringe. The gear train is configured to move the plunger of the syringe from the proximal position toward the distal position as the body is moved from the extended position toward the retracted position by a biasing force exerted by the spring unit.
