New Jet Irrigation Bipolar System

Abstract

Irrigation bipolar systems are particularly useful for the washout of hematomas in subarachnoid hemorrhage during the acute stage of surgery and for preventing adherence of tissue to the bipolar tips during coagulation. These systems have become essential tools, and numerous improvements have been made to them. First, regarding the flow volume, both the interval of droplets and the size of individual water droplets can be adjusted. Second, this system is equipped with two major functions. The first is a preirrigation function, in which a small amount of irrigation water flows before operation of the bipolar coagulation. This wets the bipolar tips, eliminating any heat remaining from the previous use. Another function is postirrigation; after the coagulation has stopped, continuous irrigation is quickly provided to achieve a standby state by cooling down the tissue and the tips of the bipolar forceps. By using both of these functions, mild coagulation without adherence of burned tissue and clots to the bipolar forceps and minimization of residual heat during frequent use can be achieved. This article describes the new jet irrigation bipolar system and the use of an actual system that combines jet irrigation functions with the new cooling functions.

An Irrigation Suction System Using a Pressurized Fluid High-Flow Pump System in Comparison with a Standard Cuff Pressure System: Technical Note

“…8 To use only as much irrigation fluid as necessary and only when necessary, we used an IS system that unified IS tubes. Various examples of such systems are on the market, [1][2][3][5][6][7][8]10 and these are selected according to surgeon preferences. However, it is necessary to pressurize the IV irrigation fluid continuously and consistently in all these systems.…”

“…Saline, Ringer lactate solution, and artificial cerebrospinal fluid are all used for irrigation. 3,4,7,8 Because irrigation fluid bags require pressure for use in IS systems, many institutions 3,9,10 use the compression pressure bag system that is normally used to measure arterial pressure. In the past, we also used this method, although manual compression pressure bags (►Fig.…”

Antiadhesion Function between a Biological Surface and a Metallic Device Interface at High Temperature by Wettability Control

“…This phenomenon is caused by the increase in the temperature of the tips of electrical-energy-based instruments . Medical treatment in the operation room require an accurate and quick hemostasis by bipolar forceps. , In 1940, Greenwood reported and developed the first bipolar coagulation system, and since then, several bipolar forceps have been developed in which the tips are protected from the attachment of burned tissue. − All of these inventions prevent the heating up of the tips. The adhesion of tissue on the tip of bipolar forceps may increase the temperature to 70–80 °C .…”
