On Cauterization by Galvanism

Infrared Spectroscopy on Smoke Produced by Cauterization of Animal Tissue

In view of in vivo surgical smoke studies a difference-frequency-generation (DFG) laser spectrometer (spectral range 2900-3144 cm(-1)) and a Fourier-transform infrared (FTIR) spectrometer were employed for infrared absorption spectroscopy. The chemical composition of smoke produced in vitro with an electroknife by cauterization of different animal tissues in different atmospheres was investigat...

Phenol cauterization for ingrown toenails.

A new clinic was set up to deal with all toenail problems referred to a large general hospital. Ingrowing toenails were the commonest problem dealt with and phenol cauterization, either partial or complete, was the standard form of treatment. Over a 2-year period 1013 phenol cauterizations were carried out on 631 patients. After a minimum of 12 months follow-up, the recurrence rate was 2.96%. A...

A biopsy tool with integrated piezoceramic elements for needle tract cauterization and cauterization monitoring.

This paper reports the feasibility of biopsy needle tract cauterization and cauterization monitoring using an embedded array of piezoceramic microheaters. Circular heaters of lead zirconate titanate (PZT-5A), with 200 μm diameter and 70-80 μm thickness, are fabricated using a batch mode micro ultrasonic machining process. These are then assembled into cavities in the walls of 20-gauge stainless...

Radiofrequency cauterization with biopsy introducer needle.

PURPOSE The principal risks of needle biopsy are hemorrhage and implantation of tumor cells in the needle tract. This study compared hemorrhage after liver and kidney biopsy with and without radiofrequency (RF) ablation of the needle tract. MATERIALS AND METHODS Biopsies of liver and kidney were performed in swine through introducer needles modified to allow RF ablation with the distal 2 cm o...
