Abstract | There is disclosed a battery and control module for use with a surgical tool unit that includes a brushless DC motor and an energy applicator actuatable by the brushless DC motor, and that is adapted for use to perform a medical/surgical procedure, the battery and control module comprising: a housing having a void space, the housing being constructed so as to seal the void space from the ambient environment; a latch feature to cooperate with the surgical tool unit to releasably hold the housing to the surgical tool unit; at least one rechargeable cell disposed in the housing void space; contacts mounted to the housing, the contacts being positioned to connect to contacts in communication with the brushless DC motor so that current from the at least one cell can be selectively sourced to the brushless DC motor; and an H-bridge disposed in the housing void space, the H-bridge being adapted to selectively tie the at least one cell to the contacts mounted to the housing so that current can be selectively sourced from or sunk to any one of those contacts, wherein the H-bridge is configured to allow current flow through at least one of the contacts to the at least one cell so that the at least one cell can be charged by applying current to the contact through which the cell sources current to the brushless DC motor. |
