Abstract:
Background Dissection and division of tissues are widely performed in microscopic neurosurgery, especially in brain tumor resection. Dissection maneuvers can be divided into two types: sharp dissection with microscissors and blunt dissection using a dissector. It is essential to use the appropriate method according to the intraoperative situation and conditions. Therefore, specific tools for each type of dissection maneuver are required. We developed an ultrasonic microdissector, a newly designed tool that functions as both microscissors and dissector to further advance brain tumor surgery. Th

Canine jejunal free flaps were isolated by electrocautery or laparosonic coagulating shears and remained viable on a vascular pedicle. After a period of ischemia and reperfusion, the flaps were resec

Abstract:
AIM: to assess original method of hemorrhoidectomy with lateral ultrasonic dissection in cutting mode in patients with stages 3–4 hemorrhoids.PATIENTS AND METHODS: a retrospective study included 140 patients with hemorrhoids 2–4 stages. In the main group (n = 80), an original technique of lateral ultrasound dissection in cutting mode was used (patent for invention No. 2722997). Patients in the control group (n = 60) underwent Milligan-Morgan hemorrhoidectomy using electrosurgical scalpel.RESULTS: significant differences were achieved in intensity of pain syndrome, morbidity rate, which were si

Abstract:
Vulvar cancer is a rare disease, and cure rates were low until the mid-20th century. The introduction of an en bloc radical vulvectomy and bilateral groin and pelvic lymph node dissection saw them rise from 15–20% to 60–70%. However, this very radical surgery was associated with high physical and psychological morbidity. Wounds were usually left open to granulate, and the average post-operative hospital stay was about 90 days. Many attempts have been made to decrease morbidity without compromising survival. Modifications that have proven to be successful are as follows: (i) the elimination of

Abstract:
Dissection using ultrasonic aspiration is characterized by its unique tendency to spare fibrous and vascular structures during removal of parenchymal lesions. This preliminary study was undertaken to evaluate the feasibility and efficiency of tonsillectomy using the ultrasonic aspirator. Tonsillectomy was performed on 23 patients using the ultrasonic aspirator. Pericapsular removal of the tonsil was easily accomplished with complete preservation of the tonsillar pillars and minimal peritonsillar trauma. The ability to identify significant vasculature before transection, and the constant aspira

Abstract:
Molecular techniques are transforming our understanding of cellular function and disease. However, accurate molecular analysis methods will be limited if the input DNA, RNA, or protein is not derived from pure population of cells or is contaminated by the wrong cells. A novel Ultrasonic Vibration Microdissection (UVM) method was proposed to procure pure population of targeted cells from tissue sections for subsequent analysis. The principle of the Ultrasonic Vibration Cutting is analyzed, and a novel microknife is designed. A multilayer piezoelectric actuator is used to actuate a sharp needle

Abstract:
During the laparoscopic appendectomy, the base of appendix is usually secured by double endoloop ligatures or by stapler. In this article we will show our initial experience in securing the base of appendix by plastic XL hem-o-lok clip during laparoscopic appendectomy. Patient, 24 years old with acute appendicitis is admitted to the Department of Surgery. After dissection of mesoappendix and appendicular artery by ultrasonic dissector, two hem-o-lok clips are placed on the base of appendix, and another clip is placed on distal part, which will be removed. Application of clip is made by hem-o-l
