Hand-held cautery device
View Patent ↗A disposable cautery device and related methods for making and disassembling a disposable cautery device are disclosed. In one embodiment, the disposable cautery device comprises a housing having a first end and a second end. A cautery tip extends from the housing first end, and the housing second end is configured to receive a removable power source. An actuator is provided to selectively complete an electrical connection between the cautery tip and the removable power source. The actuator is disposed within a recess formed in the housing, and the recess is at least partially circumscribed by a raised rim. A top surface of the actuator is flush with or lower than the rim to inhibit inadvertent actuation of the disposable cautery device. In some embodiments, an end cap is coupled with the second end of the housing to retain the removable power source in the housing, and removal of the end cap from the housing causes the coupling between the end cap and the housing to fracture.
