The Journal of Dermatologic Surgery and Oncology
|May 1, 1989
Summary
Frigipoint, a novel handheld cryoprobe, offers safe and effective dermatologic cryosurgery. This portable device efficiently treats various skin lesions with high patient and physician acceptance.
Area of Science:
- Dermatology
- Cryosurgery
Background:
- Cryosurgery is a common dermatologic treatment.
- Existing methods may lack precision or portability.
Purpose of the Study:
- Introduce Frigipoint, a new handheld dipstick cryoprobe.
- Evaluate its efficacy and safety in treating dermatologic lesions.
Main Methods:
- Frigipoint design: thermal conductive housing, cryogen absorbent member, low-thermal conductivity handle.
- Laboratory tests in gelatin medium for cryogen delivery uniformity.
- Animal studies comparing Frigipoint to liquid nitrogen spray.
- Preliminary clinical study treating 68 lesions in 16 patients.
Main Results:
- Gelatin tests showed uniform cryogen delivery and flat-bottom ice balls.
- Frigipoint demonstrated less depth of destruction than liquid nitrogen spray in animals.
- 67 of 68 lesions resolved successfully in clinical studies.
- High patient and physician acceptance reported.
Conclusions:
- Frigipoint is an effective, safe, and portable cryosurgical instrument.
- It offers controlled focal cryosurgical treatment for diverse dermatologic applications.
- Simple operation and high acceptance make it a valuable tool.
