Description

Human body breast, lumbar surgery haptic information acquiring device
Technical field
This utility model relates to the virtual emulation technology, particularly a kind of human body breast, lumbar surgery haptic information acquiring device.
Background technology
The operation virtual emulation is the application of virtual reality technology at medical domain, is the important research direction in present digitized surgical technic field.By operation virtual emulation technology, the doctor can formulate the optimization operation plan; Also can not repeat exercise by cadaver sample, thereby reduce surgeon's operative training expense and shorten cultivation cycle, operation virtual emulation technology has overcome few, the high deficiency of operational objectives (cadaver sample) cost of the actual hands-on chance of doctor under the conventional surgical training of doctors pattern, and is significant to the quality and the efficient that improve the medical surgery training.
Spinal column is one of most important organ of human body.People's spinal lesion and fracture dislocation incidence rate are in rising trend in recent years.The internal fixation of spine operation that is implanted as the basis with pedicle screw has advantages such as cycle weak point, instant effect, often becomes doctor and patient's first-selection.The implant surgery of spinal column pedicle screw need be determined the ideal mouth that advances to hammer on vertebral body, and the relative pose of monitoring in real time between screw or operation tool and the vertebral body concerns, and, doctor's viewing area is limited, rely on the X-ray that obtains affected part repeatedly, obtain the relative pose information between implant or operation tool and the trouble bone discontinuously, this has proposed very high requirement for doctor's operation technique level.In order to improve doctor's technical merit at short notice with lower cost, be necessary to develop the operation dummy emulation system of implanting towards the spinal column pedicle screw specially.
In order to reach operation virtual emulation effect true to nature, thereby according to the different of human body vertebral body different parts physical characteristic and punching and plant the nail degree of depth, orientation, speed, the isoparametric difference of acceleration and export different feedback forces, power is felt the feedback system ingredient that is absolutely necessary.Basic power feels that feedback system comprises device for force feedback and power feel modeling.Existing power vision model involves a large amount of complicated calculations and theoretical property is very strong, and structure of human body vertebral body and biomechanics characteristic are very complicated, the true feedback force that shows in the simple power visual information that draws by Theoretical Calculation and the operation has certain difference, the fidelity of virtual emulation thereby influence is performed the operation.Compare with simple Theoretical Calculation, feel that by power harvester gathers real feedback force information in the actual pedicle screw implantation, and to carry out modeling analysis and research on this basis be a kind of more direct effective solution.
Find through literature search prior art, the patent No. is that the Chinese utility model patent " analog scalpel unit " (notification number is CN1176448C) of ZL02118522.0 discloses a kind of analog scalpel, application number is the force acquisition device that 200410031486.1 Chinese utility model patent " a kind of force acquisition device of scalpel " (publication number is CN1677064A) then discloses this analog scalpel, and application number is that 200910308169.2 Chinese utility model patent " virtual surgery haptic information acquiring device " (publication number is CN101653356A) discloses a kind of virtual surgery haptic information acquiring device.These three patents all relate to the collection of human body soft tissue force feedback information, but do not consider the clamping and positioning of operational objectives in the information gathering process (tissue), up to the present, still do not have the haptic information acquiring device of implanting virtual operation towards pedicle nail.
