“…[11] Surgeons frequently report feeling pressure in their lower limb joints and hands, in addition to discomfort and exhaustion. [12,13,14,15] The extended and repetitive use of certain ergonomic instruments could be blamed for such ailments. The broad ergonomic principles currently in use for hand tool design lack specificity, making them unsuitable for the design regarding laparoscopic instruments [14,16].…”

Researches are now being conducted on redesign as well as micro ergonomic interventions. Most micro-surgical tool designs concentrate on the manipulation of targeted tissue instead of the surgeon's hand, and this presents a new research opportunity for better fitting the equipment to the surgeon's hand. So the objective is to examine the advancements made in the last few years and provide a framework for ergonomic intervention framework regarding manufacturing systems. With the use of words like ergonomic design, intervention, and evaluation," the titles and abstracts of ergonomics publications were filtered to find relevant research. The paper describes the way that the concept of micro-ergonomics can enhance the design of the micro-instruments. Finally, an application of a new surgical instrument is stated as a pen needle holder designed by SOLIDWORK 22 which creating a wide range of possible uses for futuristic technology. In future, neurosurgical equipment design will incorporate concepts from surgical tool design together with penization, microergonomics, and electronics.

“…Several studies have been conducted to show that pistol-type handles cause less muscle exertion and less difficulty in completing tasks compared to ring-type handles [5][6][7]23,37,40,41]. A larger contact area has been proven to reduce the discomfort and pain in the palm and fingers [8,22,37,[42][43][44]. Moreover, the ergonomic criterion of avoiding extreme hand postures has been evaluated in previous studies [8,16,23,37,45,46].…”

Laparoscopic surgery (LS) has been shown to provide great benefits to patients compared with open surgery. However, surgeons experience discomfort, low-efficiency, and even musculoskeletal disorders (MSDs) because of the poor ergonomic design of laparoscopic instruments. A methodology for the ergonomic design of laparoscopic dissector handles considering three-dimensional (3D) hand anthropometry and dynamic hand positions was addressed in this research. Two types of hand positions for grasping and stretching were scanned from 21 volunteers using a high-resolution 3D scanner. The 3D anthropometric data were extracted from these 3D hand pose models and used to design an improved handle (IH) that provides additional support for the thumb, a better fit to the purlicue, and a more flexible grasp for the index finger. Thirty subjects were invited to evaluate the IH in terms of muscular effort, goniometric study of motion, and efficiency and effectiveness during four trials of a laparoscopic training task. Questionnaires provided subjective parameters for ergonomic assessment. Positive results included less muscle load in the trapezius as well as significant but small angular differences in the upper limb. No significant reduction in the trial time and no increased percentage of the achievement were observed between the IH and the commercial handle (CH). Improved intuitiveness, comfort, precision, stability, and overall satisfaction were reported. IH provides significant ergonomic advantages in laparoscopic training tasks, demonstrating that the proposed methodology based on 3D anthropometry is a powerful tool for the handle design of laparoscopic dissectors and other surgical instruments.

“…Although the techniques of MIS have already attained a relatively high level of development, the ergonomic characteristics of the tools it uses are still deficient [17,[26][27][28][29][30][31]. Surgeons frequently complain of pressure, pain, and fatigue in their hands while using these instruments, which frequently result in lesions [26,28,29,[32][33][34][35][36][37]. According to Trejo et al [36], these lesions can be attributed to the repetitive and prolonged use of unergonomic instruments.…”

An Ergonomic Customized-Tool Handle Design for Precision Tools using Additive Manufacturing: A Case Study

et al. 2018

View full text Add to dashboard Cite

A study was carried out with 135 surgeons to obtain a surgical laparoscopic grasper handle design that adapts to the size of each surgeon's hand, in a functionally appropriate way, and has the sufficient ergonomics to avoid generating the problems detected nowadays. The main conclusion of the work is the practical 3D parametric design obtained for a laparoscopic surgical graspers handle that is scalable to fit each particular surgeon's hand size. In addition, it has been possible to determine that the anthropometric measure of the surgeon's hand defined as Palm Length Measured (PLM) allows the design of the 3D parametric model of the surgical handle to be conveniently scaled. The results show that both additive manufacturing and the application of ergonomics criterion provide an efficient method for the custom design and manufacture of this type of specialised tool, with potential application in other sectors.

Abstract: A clear recommendation for any one of the three currently available handles cannot be given. The results obtained with a simple model of a multifunctional handle were highly promising, and it may be possible to extend it to a real multifunctional instrument.
