The aim of this study is to compare the repair of incisions performed with microdissection electrocautery tip, conventional electrocautery tip, high potency diode laser, and conventional scalpel blade in a in vivo model.
Different incisions were performed in adults Holtzman rats using the four types of instruments: microdissection electrocautery tip, conventional electrocautery tip, high potency diode laser, and conventional scalpel blade, in different periods of healing process. Thirty rats were divided into 5 groups, according to the period of euthanasia-24 h, 48 h, 72 h, 7 days, and 14 days. All animals received four incisions, each by a different method. Quantitative histological and histomorphometric analyses were performed using hematoxylin and eosin (HE) and Picrosirius Red staining.
Inflammatory profile and tissue repair presented small statistically significance differences comparing conventional scalpel blade and microdissection tip; moreover, both presented quantitatively superior to the others.
It is believed that the microdissection tip can perform a dynamic incision just as a common scalpel blade, but more effective. Furthermore, it can promote a better hemostatic control of the surgical field that is comparable to conventional electrocautery tip without affecting tissue repair.
本研究旨在比较在体内模型中使用显微解剖电灼尖端、传统电灼尖端、高效二极管激光和传统手术刀刀片进行切口修复的效果。
使用四种仪器（显微解剖电灼尖端、传统电灼尖端、高效二极管激光和传统手术刀刀片）在成年霍尔茨曼大鼠身上进行不同的切口，在不同的愈合过程时期进行。30 只大鼠根据安乐死时间（24 小时、48 小时、72 小时、7 天和 14 天）分为 5 组。所有动物均接受了 4 种不同方法的 4 次切口。使用苏木精和曙红（HE）和苦味酸天狼星红染色进行定量组织学和组织形态计量学分析。
与传统手术刀刀片相比，常规电灼尖端和显微解剖尖端的炎症特征和组织修复差异较小，但在数量上均优于其他两种方法。
我们认为，显微解剖尖端可以像普通手术刀刀片一样进行动态切口，但更有效。此外，它可以更好地控制手术区域的止血，与传统电灼尖端相当，而不会影响组织修复。
