Ball probes deliver a symmetrical, dome-like freezing imprint of various sizes for cryosurgical procedures. Contact probes must be decontaminated after every patient use. Ball probes can be used for ulcerated tumours, large tumours, underlying bony structures or for a domelike symmetrical freeze in soft tissue.
All contact probes come fitted a silicone exhaust tube to ensure the vented LN2 is directed away from the user and patient.
By applying pressure onto a lesions with a Contact probes you can reduce vascular flow, create a quicker deeper freeze and thus reduce the a freeze time.
