Membranous labyrinth model manufacturing method

Abstract

The invention discloses a membranous labyrinth model manufacturing method. The method comprises the steps that clinic MRI is adopted for obtaining a plurality of pieces of source data of the inner earof an able-bodied person, the source data is processed through 3D Slicer, a Meshlab and netfab software in sequence to form a plurality of pair of inner ear eyeball bony labyrinth models, one inner ear eyeball bony labyrinth model is selected as a reference model for performing rectification, the inner ear eyeball bony labyrinth statistical shape model is exported, the source data is used for manually cutting the membranous labyrinth model, the membranous labyrinth model and the inner ear eyeball bony labyrinth statistical shape model are calibrated, the model is printed through the 3D printing technology, the model is more precise, the space direction is determined, and the method is applied to teaching model demonstration or otolithiasis treatment assistance.

Description

Technical field [0001] The invention relates to the field of medical equipment, and more specifically to a method for making a membrane labyrinth model. Background technique [0002] The inner ear is located in the deep part of the temporal bone and has a delicate and complex structure. It is also called the labyrinth, including the bony labyrinth and its inner membrane labyrinth. The main parts of the membranous labyrinth are the utricle, balloon, membranous semicircular canal and cochlea. The membrane labyrinth is full of endolymph, and the outer bony labyrinth and perilymph play a protective role. Utricles and balloons are located in the vestibular cavity of the bony labyrinth. The front of them is the cochlea and the back are three semicircular canals. There is a short tube communicating between the two sacs, and the semicircular canal and the cochlea are connected to the two sacs respectively, so the endolymph between the various parts of the membranous labyrinth is connec...

Problems solved by technology

However, there are problems in addition to the lack of objective evidence for the representativeness of the reference model. Due to the difference in shape, mutual calibration is also difficult to match, which will cause measurement errors.

[0007] Existing models are all made of bone labyrinth or bone semicircular canal models as auxiliary devices for the treatment of otolithiasis reset method. The therapeutic aids can guide the rotation and reset of otoliths during body position rotation during use, but the spatial direction of the labyrinth model The establishment of the lack of specific instructions
