“…AM has also allowed the design of smart steerable needles, the first bipolar steerable forceps, and a 3D-printed device for trans-anal endoscopic surgical procedures that provide adequate working space without inflating the rectum [129] . In summary, AM technology has contributed significantly to the medical field, providing innovative solutions and improved patient outcomes.…”

“…The AM prototypes were used to adapt the design, which greatly reduced the required time and improved communication with non-design professionals. Through collaborative work between engineers and surgeons, a mechanical distractor was designed to provide a diaphanous work space without using pneumorectum (Rodríguez García et al , 2018, 2021). After evaluating various options, a device of some complexity was designed to provide the required work space.…”

Purpose This paper describes the evolution of the design of a mechanical distractor fabricated using additive manufacturing (AM) technology for use in surgical procedures, such as transanal endoscopic microsurgery (TEM). The functionality of the final device was analysed and the suitability of different materials was determined. Design/methodology/approach Solid modelling and finite element modelling software were used in the design and validation process to allow the fabrication of the device by AM. Several prototypes were manufactured and tested in this study. Findings A new design was developed to greatly simplify the existing devices used in TEM surgery. The new design is easy to use, more economical and does not require pneumorectum. Different AM materials were investigated with regard to their mechanical properties, orientation of parts in the three-dimensional (3D) printer and cytotoxicity to select the optimal material for the design. Social implications The device designed by AM can be printed anywhere in the world, provided that a 3D printer is available; the 3D printer does not have to be a high-performance printer. This makes surgery more accessible, particularly in low-income regions. Moreover, patient recovery is improved and pneumorectum is not required. Originality/value A suitable mechanical distractor was designed for TEM, and different materials were validated for fabrication by AM.

Purpose Laparoscopic surgeons suffer because of discomfited body posture while performing surgery and experience discomfort owing to lack of customized surgical instruments. Accordingly, this paper aims to recommend an individual customization strategy by developing an ergonomically designed laparoscopic forceps handle and thereby increase the comfort of surgeons. Design/methodology/approach Hand anthropometric parameters of 282 south Indian male subjects are used to customize the handle. uPrint and Objet260 Connex, which works based on fused deposition modeling and PolyJet, respectively, are used to fabricate the prototype of the handle. Design modifications include a pistol-type grip, the increased contact area between the hand and handle, and neutral wrist posture. Findings Ergonomic evaluation parameters such as grip, functionality, comfort and wrist posture using subjective ratings from laparoscopic surgeons were recorded and obtained average values of 4.1, 3.6, 4.1 and 4.1, respectively, based on a five-point ordinal scale. Additionally, stress analysis also confirms the safety of the handle based on von Mises stress criteria. Research limitations/implications Anthropometric data are limited to 282 subjects and subjective evaluation is conducted using a prototype, not the end-use product. Originality/value Evaluation using subjective rating confirms the ascendancy of a modified handle over the existing handle in terms of assessed parameters. The proposed individual customization strategy can be applied for other industrial hand tools to enhance comfort.
