概括
在使用腹腔镜仪器时,手手较小的外科医生会经历更高的前臂肌肉炼 (%MVC). 这种增加的激活可能会增加受伤风险,突出了考虑到外科医生手的大小的仪器设计的需要.
科学领域:
- 微创手术是最少的侵入性手术.
- 外科手术的人体工程学
- 生物力学 生物力学
背景情况:
- 百分比最大自愿收缩 (%MVC) 是对肌肉炼的正常化指标.
- 在外科手术过程中较高的%MVC可以增加肌肉疲劳和受伤风险.
- 拉帕里特能量装置的设计各不相同,可能会影响外科医生的生物力学.
研究的目的:
- 在使用四种腹腔镜能量装置时评估前臂肌肉%MVC.
- 为了比较不同手大小的外科医生之间的肌肉活动差异.
- 为了确定与腹腔镜仪器设计相关的潜在人体工程学风险.
主要方法:
- 在24名外科医生和外科实习生中进行了一项非实验相关性研究.
- 表面电肌图 (sEMG) 测量了前臂肌肉活动 (FDS,ECU,ECR,EPL).
- 在使用四种能量装置模拟腹腔镜任务时,肌肉炼正常化至%MVC.
主要成果:
- 手手较小的外科医生 (手套大小≤6.5) 显示前臂肌肉激活 (FDS和ECR) 显著更高.
- 在16个肌肉/仪器组合中,有10个超过了小手外科医生15%的MVC值.
- 在大手外科医生中,只有一个组合超过了15%的MVC值.
结论:
- 小手的外科医生在腹腔镜仪器上表现出前臂肌肉激活的增加.
- 目前的腹腔镜能量装置设计可能会不成比例地使手部较小的外科医生受到伤害的风险.
- 仪器制造商在人体工程设计中应考虑外科医生手的尺寸变化.

Muscles of the Forearm that Move the Hand and Fingers
2.3K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Muscles that Move the Forearm
3.7K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
