Background

Since the unergonomic postures cannot be changed during a surgery, it seems reasonable to externally support the surgeon's posture in order to relieve the musculature. To evaluate this matter, we conducted a pilot study to investigate if a prototype of an external surgeon support system (S3) relieves the musculature in an objectively measurable manner.

Methods

Simultaneous surface electromyography (EMG) was used alongside a combination of a laser Doppler flowmeter and a tissue spectrometer to record back and leg muscles during a simulated surgical situation.

Findings

With S3, muscle activity was significantly lower (p < 0.05) and also fatigue decreased when compared to without S3. Muscle blood flow and oxygenation were relatively close to baseline with S3, but increased without S3.

Interpretation

An ergonomic S3 is a possible approach to reduce muscle activity and fatigue and may therefore prevent chronic back pain amongst surgeons in the long term.

外科医生的人体工程学——外科医生支持系统的原型减少肌肉活动和疲劳

背景

由于在手术过程中不能改变不符合人体工程学的姿势，从外部支撑外科医生的姿势以减轻肌肉组织似乎是合理的。为了评估这个问题，我们进行了一项试点研究，以调查外部外科医生支持系统 (S3) 的原型是否以客观可衡量的方式减轻肌肉组织。

方法

同时表面肌电图 (EMG) 与激光多普勒流量计和组织光谱仪的组合一起用于在模拟手术情况下记录背部和腿部肌肉。

发现

与没有 S3 的情况相比，S3 的肌肉活动显着降低 (p < 0.05)，疲劳也减少。肌肉血流量和氧合与 S3 的基线相对接近，但在没有 S3 的情况下增加。

解释

符合人体工程学的 S3 是一种减少肌肉活动和疲劳的可能方法，因此可以长期预防外科医生的慢性背痛。
