Shaw Scalpel Research Articles

The Shaw Scalpel.

The Shaw Scalpel is a new relatively inexpensive electric scalpel that produces cold-steel scalpel accuracy with instant coagulation of most blood vessels encountered in dermatologic surgery. It surely will become a favorite instrument for dermatologic surgeons.

熱メス（Ｓｈａｗ ｓｃａｌｐｅｌ）の基礎実験および臨床応用

1) ラットの皮膚切開で著明な止血効果を認めた. しかし, 術後7日目には, 切開部〓開を招いた.2) ウサギの皮膚組織標本では, 110℃では約300μm, 260℃では約600μmの範囲に熱変性が及んでいた.3) 頭頸部外科手術22症例に用いて, 合併症は認められなかった. 皮下剥離に用いると良好な止血効果があり, 手術時間の短縮になった.4) 皮弁や筋皮弁作成術, 耳下腺手術等にはことに有効であろう.

Use of the Shaw scalpel in head and neck surgery.

Fifty patients undergoing a variety of head and neck surgical procedures were used to study a new thermally activated scalpel. No electric current passes through the patient and, thus, no ground pad is needed. Subjective equipment evaluation resulted in mean scores of 3.8 (1 = worthless and 5 = excellent) for effectiveness of hemostasis and 4.1 for blade sharpness. The Shaw scalpel system is a worthwhile surgical tool 70% of the time. It is excellent for raising flaps and for use in precise surgery where small capillary bleeding typically obscures visibility (ie, parotid surgery).
