“…The results of that work are summarized in Table 2. It should be noted that, in addition to this study of González et al [18], other workers have proposed different sizes for surgical handles and hand tools, specifically by defining three sizes [5,16,[39][40][41]. Nonetheless, given the precision required in surgery and the many hours that some operations last [36], together with the technological means available today such as additive manufacturing and the development of 3D parametric design software [42], a personalized solution would seem to be called for, with the handle being designed to have the size ergonomically best suited to the anthropometric dimensions of each surgeon's hand.…”

“…These criteria eliminated the possibility of a handle design with rings. The resulting handle design has been studied and further analyzed in the work of González et al [18]. In that study, a first approach was to define a grasper handle size that would best suit the surgeon's hand size, but without attempting to customize the design as this is the purpose of the paper at hand, considering designs based on four hand sizes (XS, S, M, and L).…”

“…The length of the handle and its diameter were increased relative to the handles traditionally used in MIS, as this provides a better fit for different hand sizes, and the fingers have a larger contact surface thus reducing the pressure on localized areas, especially the thumb. The resulting handle design has been studied and further analyzed in the work of González et al [18]. In that study, a first approach was to define a grasper handle size that would best suit the surgeon's hand size, but without attempting to customize the design as this is the purpose of the paper at hand, considering designs based on four hand sizes (XS, S, M, and L).…”

“…Using data from the work of Greiner [45], DiMartino et al [16] defined three categories of hand tools (small, medium, and large) in accordance with hand length. To reduce the number of anthropometric data that we needed to employ in this study, we carried out a comparative study of the different lengths studied by Greiner [45] and those studied by González et al [18].…”

“…Other studies indicate that the shape of the handle should be designed to optimize the performance of the tasks in which the tool is to be used [9], maximize the ease of use and contact area between the hand and the handle [10,14], and to distribute pressure so as to minimize discomfort [11,12]. Other anthropometric studies have had the aim of determining laparoscopic surgery instrument dimensions that adapt to different hand sizes [8,[15][16][17][18]. However, it should be noted that these last works defined three or four sizes for the handle, but listed no criterion for the design of a handle customized for each surgeon.…”

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.

Does surgeon sex and anthropometry matter for tool usability in traditional laparoscopic surgery? A systematic review and meta-analysis

Introduction Hand size, strength, and stature all impact a surgeon’s ability to perform Traditional Laparoscopic Surgery (TLS) comfortably and effectively. This is due to limitations in instrument and operating room design. This article aims to review performance, pain, and tool usability data based on biological sex and anthropometry. Methods PubMed, Embase, and Cochrane databases were searched in May 2023. Retrieved articles were screened based on whether a full-text, English article was available in which original results were stratified by biological sex or physical proportions. Article quality was discussed using the Mixed Methods Appraisal Tool (MMAT). Data were summarized in three main themes: task performance, physical discomfort, and tool usability and fit. Task completion times, pain prevalence, and grip style results between male and female surgeons formed three meta-analyses. Results A total of 1354 articles were sourced, and 54 were deemed suitable for inclusion. The collated results showed that female participants, predominantly novices, took 2.6–30.1 s longer to perform standardized laparoscopic tasks. Female surgeons reported pain at double the frequency of their male colleagues. Female surgeons and those with a smaller glove size were consistently more likely to report difficulty and require modified (potentially suboptimal) grip techniques with standard laparoscopic tools. Conclusions The pain and stress reported by female or small-handed surgeons when using laparoscopic tools demonstrates the need for currently available instrument handles, including robotic hand controls, to become more size-inclusive. However, this study is limited by reporting bias and inconsistencies; furthermore, most data was collected in a simulated environment. Additional research into how anthropometric tool design impacts the live operating performance of experienced female surgeons would further inform this area of investigation.
