Liver Biopsy by Needle
در نمونه برداری سوزنی کبد یا آسپیراسیون کبد، توسط سوزن نمونه برداری می توان نمونه ای از بافت کبدی را جهت تشخیص اکثر اختلالات کبدی، اثبات وجود سرطان کبد، یا ارزیابی اثرات داروهای آسیب رساننده به کبد تهیه کرد. همچنین با انجام نمونه برداری های مکرر روند پیشرفت و پاسخ بیماران به درمان بیماری های کبدی مزمنی چون هپاتیت فعال را می توان مشخص نمود.
متن کاملExperimental study of needle-tissue interaction forces: effect of needle geometries, insertion methods and tissue characteristics.
A thorough understanding of needle-tissue interaction mechanics is necessary to optimize needle design, achieve robotically needle steering, and establish surgical simulation system. It is obvious that the interaction is influenced by numerous variable parameters, which are divided into three categories: needle geometries, insertion methods, and tissue characteristics. A series of experiments a...
متن کاملDataset on force measurements of needle insertions into two ex-vivo human livers
A needle-tissue interaction experiment has been carried out, by inserting the inner needle of a trocar needle into two ex-vivo human livers. The dataset contains the forces that act on the needle during insertion and retraction into the livers. In addition, a MATLAB code file is included that provides base-level analysis of the data and generates force-position diagrams of the needle insertions...
متن کاملModeling of Needle-Tissue Interaction Using Ultrasound-Based Motion Estimation
A needle-tissue interaction model is an essential part of every needle insertion simulator. In this paper, a new experimental method for the modeling of needle-tissue interaction is presented. The method consists of measuring needle and tissue displacements with ultrasound, measuring needle base forces, and using a deformation simulation model to identify the parameters of a needle-tissue inter...
