Thompson Lithotrite
Thompson lithotrite is used for crushing stones inside the urinary bladder.
Small fragments are then sucked out under negative pressure; this avoids opening the bladder.
Identification points
· This instrument can be passed into the bladder like a bougie.
· It has two blades.
· The movement of blades is controlled by a ball or wheel at the end of the handle.
· There is a scale on the handle to indicate the distance between the blades
Uses
The instrument can catch a bladder stone between the jaws and crush it.
Modern lithotrites have optical lens to allow crushing under vision
