Problems solved by technology

However, there is currently no training aid for salivary gland endoscopic surgery, and the salivary gland duct structure of other animals is far from that of humans, so it is not suitable as a training model

Embodiment Construction

[0035] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 Shown is a schematic diagram of the overall structure of the simulated major salivary gland model device of the present invention. A device for simulating a large salivary gland model, including a large salivary gland model 1 constructed based on real-life salivary gland image data and several pathological models 2 constructed based on common clinical diseases; the large salivary gland model includes a three-level duct system 4 with a dendritic structure and The end of the duct system is connected to the acinus 5, the end of the third-level duct of the duct system 4 extends into the acinus 5, the third-level duct merges into the second-level duct, and the second-level duct merges into the first-level duct; each Pathological models 2 all have a main duct channel 6 that is compatible with the first-order duct of the large...

Abstract

The invention provides a simulated major salivary gland model device and a preparation method thereof based on the salivary gland image data of real people. The device is used for training a salivary gland endoscopic operation, and the mastery of operation skills by a doctor is facilitated. The device comprises a major salivary gland model constructed based on the salivary gland image data of the real people and a plurality of pathological models constructed based on common clinical diseases. The major salivary gland model comprises a three-level catheter system with a dendritic structure and acini which are connected to the end of the catheter system. The ends of the third-level catheters of the catheter system extend into the acinus. The third-level catheters converge to second-level catheters which converge to a first-level catheter. Each of the pathological models is provided with a main catheter channel which is matched with the first-level catheter of the major salivary gland model and can be connected to the major salivary gland model in a replaced way respectively. When two models are connected to be a whole body, the main catheter channels of the pathological models are connected to the first-level catheters of the major salivary gland models.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a simulated large salivary gland model device and a manufacturing method, which can be used for training endoscopic operations, can help trainers quickly master the operating skills of salivary gland endoscopy, and adapt to the complex anatomical environment of the salivary gland duct system Undergo endoscopy. Background technique [0002] With the popularization and deepening of the concept of minimally invasive and function-preserving surgery, endoscopic operation (surgery) has developed rapidly in various medical fields. In the field of salivary gland surgery, part of the traditional salivary gland resection can be replaced by salivary gland endoscopic surgery. In this operation, a flexible endoscope with an outer diameter of about 1.1mm is inserted into the catheter through the salivary gland duct opening, and it travels through the catheter system to reach the lesion area,...
