Embodiment Construction

[0013] The present invention utilizes the shape-sensing fiber-optic grid to carry out the surgical registration system, attaches the shape-sensing fiber-optic grid to the surface of the human body during surgery, fixes several cameras on both sides of the operating table to capture the position, and the computer system passes multiple Locate the position of the label to locate the position of the human body in space. Use flexible optical fibers to measure the shape of the shape sensing model under constant temperature and humidity conditions, and use multiple optical fibers to form a grid to obtain the surface shape information of the human body, obtain preoperative image information and input it into the registration system, and perform registration according to the edge of the human body shape Accurate, get real-time registered three-dimensional shape of the human body. There are multiple visual labels attached to the grid, and multiple cameras obtain the poses of the visual...

Abstract

The invention relates to a surgical registration system using shape sensing optical fiber grids. Due to different postures, pulse beating and spontaneous breathing movements, the actual shape of a target organ of a patient during surgery can be inconsistent with a shape obtained by preoperative image measurement, a surgical navigation system needs to register the preoperative image with a real human body in real time, and performs surgical operation based on the registered image, and human body surface shape information is an important source of information for registration. The system uses shape sensing optical fibers to weave a mesh surface, and the mesh surface is attached to the surface of a human body for real-time shape measurement of the human body surface; and the obtained result is input into a registration system of a surgical navigation device, and a computer generates a real-time stereoscopic image of the human body according to a CT scan image obtained by preoperative human body scanning to guide a doctor to perform more accurate surgical operation.

Description

technical field [0001] The invention relates to a surgical image technology, in particular to a surgical registration system using a shape-sensing optical fiber grid. Background technique [0002] In many clinical operations, the shape and position of the target organ of the human body must be accurately obtained. However, respiration and the beating of the heart will cause slight changes in the position of the internal organs of the human body. Obtaining traditional medical images will always produce errors during surgery. Digitalization and software programs cannot fully play a role in surgery. Currently, registration is mainly performed through surgical navigation technology, and the registered images have limitations. [0003] Optical fibers are flexible and can accurately reconstruct the shape of the human body surface. The shape-sensing fiber optic grid is attached to the surface of the human body, which can not only accurately sense the external shape of the human bo...
