Cryosurgery
Cryotherapy is often the best way to treat a number of pathologies. Tissue subjected to temperatures below -20°C is destroyed. The freezing of the cells causes them to burst. The destroyed tissue stays in place until healing is completed and it then sloughs off. Because of this, the risk of infection is almost zero. Procedures such as electrosurgery, cautery, and removal by scalpel are all more prone to infection and scars are usually left. Cryosurgery does not normally cause the formation of scar tissue although pigmentation will be lost, sometimes permanently.
The most common applications are for the removal of warts and verruccae, cryosurgery of the cervix to treat CIN, treating Condylomata, treating retinal detachment, and for several other ophthalmic procedures, and dermatology.
The Wallach LL100 Multitip Cryosurgery system
Wallach
LL100 Multitip cryosurgery system for a wide variety of general, gynaecological,
GU medicine application, and dermatology.
This uses a cylinder of nitrous oxide or carbon dioxide to freeze any one of a variety of tips that are connected. The appropriate tip for the application is selected and screwed in place. The tip is placed against the tissue to be frozen and the Freeze trigger is pressed. One can see an ice-ball radiating around the tip. This is in the form of a hemisphere below the tip. It is important to freeze 1-2 mm into healthy tissue to be certain to destroy the lesion. There is no risk of damage to bone or permanent damage to the nerves or circulation.
The Wallach LL100 is the instrument of choice for treating the cervix, condylomata, warts and verruccae. For further information, and copies of clinical papers, contact Genesis Medical Limited.
The Wallach Ultrafreeze Liquid Nitrogen Spray
This
instrument is designed to hold 300ml or 500ml of liquid nitrogen for 12-24
hours, during which time evaporation takes place continuously. For best
results, the liquid nitrogen (at -160°C) is sprayed directly onto
the lesion through one of a variety of spray apertures.
Liquid nitrogen is particularly effective for larger shallow lesions and suited for many dermatological conditions.
For confined lesions such as warts, a variety of closed tips are available but the results are less satisfactory than with the Wallach LL100.
