To evaluate tissue effect of J-Plasma® (Bovie Medical Corporation, Clearwater, Florida) in porcine liver, kidney, muscle, ovarian, and uterine tissue blocks.
Prospective study utilizing porcine tissue blocks to evaluate the thermal spread of J-Plasma® device on liver, kidney, muscle, ovarian, and uterine tissue at various power settings, gas flow, and exposure times.
J-Plasma® helium was used in porcine liver, kidney, and muscle tissue at 20%, 50%, and 100% power, and 1 L/min, 3 L/min, and 5 L/min gas flow at one, five, and 10-second intervals. J-Plasma® was then used in ovarian and uterine tissue at maximum power and gas flow settings in intervals of one, five, 10, and 30 seconds. Histologic evaluation of each tissue was then performed to measure thermal spread.
Regardless of tissue type, increased power setting, gas flow rate, and exposure time correlated with greater depth of thermal spread in liver, kidney, and muscle tissue. J-Plasma® did not exceed 2 mm thermal spread on liver, kidney, muscle, ovarian, and uterine tissue, even at a maximum setting of 100% power and 5 L/min gas flow after five seconds. Prolonged exposure to J-Plasma® of up to 30 seconds resulted in increased length and width of thermal spread of up to 12 mm, but did not result in significantly increased depth at 2.84 mm.
The J-Plasma® helium device has minimal lateral and depth of thermal spread in a variety of tissue types and can likely be used for a multitude of gynecologic surgical procedures. However, further studies are needed to demonstrate device safety in a clinical setting.
评估J-Plasma®（博维医疗公司，佛罗里达州克利尔沃特）对猪肝、肾、肌肉、卵巢和子宫组织块的组织效应。
前瞻性研究，利用猪组织块评估J-Plasma®设备在不同功率设置、气体流速和暴露时间下对肝脏、肾脏、肌肉、卵巢和子宫组织的热扩散情况。
在猪肝、肾和肌肉组织中使用J-Plasma®氦气，功率分别为20%、50%和100%，气体流速为1L/min、3L/min和5L/min，暴露时间间隔为1秒、5秒和10秒。然后在卵巢和子宫组织中以最大功率和气体流速设置，暴露时间间隔为1秒、5秒、10秒和30秒使用J-Plasma®。随后对每个组织进行组织学评估以测量热扩散情况。
无论组织类型如何，功率设置增加、气体流速增加和暴露时间延长与肝脏、肾脏和肌肉组织中热扩散深度增加相关。即使在5秒后最大功率设置为100%功率和5L/min气体流速的情况下，J-Plasma®在肝脏、肾脏、肌肉、卵巢和子宫组织上的热扩散也未超过2mm。长时间暴露于J-Plasma®长达30秒会导致热扩散的长度和宽度增加至12mm，但深度在2.84mm时并未显著增加。
J-Plasma®氦气设备在多种组织类型中的横向和深度热扩散最小，可能可用于多种妇科手术。然而，需要进一步研究以证明该设备在临床环境中的安全性。
