To improve the efficiency of medical staff in surgical operations and meet the physiological and psychological needs of surgeons, nurses, and patients during the operations, surgical auxiliary equipment is designed. This paper builds a design research model based on AHP (analytic hierarchy process), QFD (quality function deployment), and Platts conceptual decision matrix (PUGH decision matrix). Firstly, the user requirements are weighed through AHP analysis, and the design elements are prioritized based on the weight values. Then, QFD is used to analyze the design features of surgical auxiliary equipment from the aspects of structure, function, and shape, and a house of quality is established to get the significance of design features. Finally, the PUGH decision matrix is constructed to screen and evaluate multiple schemes, and the optimal design scheme is obtained. From the perspective of user requirements and product design characteristics, the significance of design elements is analyzed and calculated, which guides the design practices to complete the innovative design of surgical auxiliary equipment. The combination of AHP, QFD, and PUGH decision matrices are introduced into the innovative design of surgical auxiliary equipment, effectively avoiding subjective factors in product design, improving the scientific nature of the design, and providing new methods and ideas for the design and research of surgical auxiliary equipment and similar products.

A console is an important platform for controlling indoor operations and displaying information. It is an important device for human-computer interactions. Whether an operator is comfortable using a console is an important issue of concern in industry. However, previous works have focused only on the joint angle and muscle fatigue of the console user, with few works focusing on the eye comfort of users. In this paper, we propose a console design method based on the physical comfort of the human eye to allow consoles to satisfy the needs of a user regarding the joint angle and muscle comfort and to reduce the physiological fatigue of a user's eyes, thereby improving the operator's cognitive efficiency and accuracy. In addition, a software and hardware collaboration platform is used to effectively improve the stability and accuracy of the proposed method. We also propose a method for evaluating the human eye comfort of console users based on a dual-channel objective visual quality analysis system. To the best of our knowledge, this is the first work to propose an evaluation metric for determining the comfort of the human eye afforded by a console, and experiments in the real world verify the effectiveness of this metric. Through this evaluation method, a console designed by using the console optimization method proposed herein is compared with a console designed according to the previous console design method. The results prove that our proposed method can effectively improve human eye comfort when using a console.INDEX TERMS Console, optimal design, comfort evaluation, visual quality evaluation.
