Surgical clip applier having a wireless clip counter
First Claim
1. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
- a housing;
at least one handle pivotably connected to the housing;
a channel assembly extending distally from the housing;
a clip carrier disposed within the channel assembly and defining a channel and a plurality of windows therein;
anda counter mechanism supported in at least one of the housing and the channel assembly, wherein the counter mechanism is configured to transmit a change in status of the apparatus upon each actuation of the at least one handle, wherein the counter mechanism comprises;
a switch configured to output a signal upon actuation of the at least one handle;
an encoder configured to output a bit sequence upon actuation of the switch;
a radio frequency transmitter operable to convert the bit sequence into a radio frequency signal; and
a transmitting antenna configured to transmit the radio frequency signal.

Abstract
An apparatus for application of surgical clips to body tissue is provided and includes a housing, at least one handle a channel assembly, a clip carrier disposed within the channel assembly and a counter mechanism supported in at least one of the housing and the channel assembly. The counter mechanism is configured to transmit a change in status of the apparatus upon each actuation of the at least one handle. The counter mechanism includes a switch configured to output a signal upon actuation of the trigger, an encoder configured to output a bit sequence upon actuation of the switch, a radio frequency transmitter operable to convert the bit sequence into a radio frequency signal, and a transmitting antenna configured to transmit the radio frequency signal.

2. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
-
a handle assembly having a trigger; a shaft assembly including a housing extending distally from the handle assembly and defining a longitudinal axis; a jaw mounted adjacent a distal end portion of the shaft assembly, the jaw being movable between an open spaced-apart condition and a closed approximated condition; and a counter mechanism supported in the handle assembly, wherein the counter mechanism provides an indication when a surgical clip has been fired upon activation of the trigger, wherein the counter mechanism comprises; a switch configured to output a signal upon actuation of the trigger; an encoder configured to output a bit sequence upon actuation of the switch; a radio frequency transmitter operable to convert the bit sequence into a radio frequency signal; and a transmitting antenna configured to transmit the radio frequency signal.
