This report presents the experience in a prospective series of 100 operative procedures in all fields of paediatric surgery with the Shaw haemostatic scalpel, which we have subsequently used in more than 3000 further operations. The Shaw scalpel proved to be advantageous in about 80% of major cases. The scalpel cuts tissue with a sharp steel edge, like a cold scalpel, and simultaneously seals blood vessels by heat thermally conducted to the tissue from heated blade which is electrically insulated from the patient. The heat seals most small blood vessels (under 2 mm) as they are cut. Since no electric current passes through the patient, a grounding pad is not needed and the risk of accidental electrical current burns at grounding sites is eliminated. Muscle stimulation associated with the use of a normal cautery is avoided, improving surgical precision of cutting. The Shaw haemostatic scalpel minimizes damage to the tissue as compared with other thermocoagulating instruments. Since it seals small vessels as it cuts tissue, it largely eliminates the flow of blood into the incised area and allows better visibility of the surgical field. The use of the scalpel requires a different cutting technique which is however easy to learn. The Shaw haemostatic scalpel reduces blood loss and overall operating time in major cases. It is relatively inexpensive and can be recommended for use in paediatric surgery.
本报告介绍了使用肖氏止血手术刀进行的100例小儿外科各领域手术的前瞻性系列经验，我们随后又在3000多例手术中使用了该手术刀。在约80%的主要病例中，肖氏手术刀被证明具有优势。该手术刀用锋利的钢刃切割组织，就像冷手术刀一样，同时通过与患者电绝缘的加热刀片传导至组织的热量来封闭血管。在切割时，热量可封闭大多数小血管（2毫米以下）。由于没有电流通过患者，因此无需接地垫，消除了接地部位意外电流灼伤的风险。避免了与使用普通电灼器相关的肌肉刺激，提高了手术切割的精度。与其他热凝器械相比，肖氏止血手术刀对组织的损伤最小。由于它在切割组织时封闭小血管，在很大程度上消除了血液流入切口区域的情况，使手术视野更清晰。使用该手术刀需要一种不同的切割技术，但这种技术很容易掌握。肖氏止血手术刀可减少主要病例中的失血量和总手术时间。它相对便宜，可推荐用于小儿外科手术。
