Research On The Design Of Puncture Robot Based On Perceptual Imagery

Puncture surgery is a common method for tissue sampling and minimally invasive treatment of cancer pathological diagnosis.The traditional image-guided puncture operation not only has high requirements on the doctor’s experience and surgical status,but also requires multiple scans under the guidance of medical images such as CT,which will increase the radiation of both doctors and patients.In order to solve the above problems,some enterprises,universities,and hospitals around the world have participated in the development of puncture robots.At present,the medical puncture system in the market basically meets the functional requirements,but the domestic medical equipment has a relatively short history of research and development,a low degree of product innovation,the design is rough,and the product competitiveness is not strong.Because of the above problems,this paper from the perspective of industrial design,carries out innovative design research on the functional structure and appearance modeling scheme of medical puncture robot,constructs innovative design method and process of medical equipment,and provides enterprises with innovative design schemes of medical puncture robot with good feasibility and economy.Firstly,through field observation,offline interviews,literature research,and other methods to obtain situational information,using the Scenario Analysis to construct the using situation of puncture robots,and then mining user needs.The KJ method is used to sort out the demand items and construct the hierarchical structure model of user demand for medical puncture robot.Using the Kano model and the Better-Worse coefficient to calculate the relative user satisfaction,the demand items are classified and sorted.Secondly,the functional analysis method is used to analyze the functional structure of related typical products,the total function of the medical puncture robot is determined according to the user’s needs,and the innovative design of the functional tree and functional structure is carried out.The functional elements are solved and sorted into the morphological matrix of the functional element carrier,multiple functional principle schemes are obtained by combination,and functional principle innovation schemes with high feasibility are selected.Thirdly,the multiscale method is used to select typical samples from the collected medical puncture robot modeling samples,and the SD(Semantic Difference)method and factor analysis method are used to determine the representative image vocabulary and construct the perceptual image semantic space.The mapping model between the multi-objective image and modeling form,color,and material elements of medical puncture robot is constructed by using the quantification theory type I.The correlation analysis between representative image vocabulary and design elements is carried out by using the multiple linear regression method,and the multiobjective optimization design model of medical puncture robot modeling is constructed.Finally,based on the functional principle innovation scheme of the design,the correlation analysis results of perceptual image and modeling,combined with the theory of ergonomics,the appearance modeling scheme of the medical puncture robot is designed.Based on the user’s needs,the evaluation index of the scheme is determined,and the fuzzy comprehensive evaluation method is used to determine the relative optimal conceptual design scheme of the medical puncture robot.The structural design and prototype construction of the preferred scheme are carried out.Through the simulation analysis of the use situation of the prototype,the rationality and environmental coordination of the conceptual design scheme of the medical puncture robot are verified.
