Description

A model of neck biopsy

technical field

The utility model relates to the field of medical technology, in particular to a neck puncture biopsy model.

Background technique

In the medical field, needle biopsy of neck masses has important clinical significance for the selection of treatment options for neck diseases. However, the anatomy of the neck is a more complex part of the human body, mainly due to the complex routing of blood vessels, trachea and nerves.

In actual clinical work, needle biopsy of neck organs and lesions is an important part of interventional ultrasound teaching. When a tumor grows in the neck, ultrasound examination and needle biopsy can be used to accurately characterize the tumor. However, before the actual clinical work, young interventional sonographers need to use the simulated neck lesions and organs for operation exercises in order to master the correct operation methods of ultrasonic intervention. A teaching aid for practicing ultrasound intervention in neck masses.

Ultrasound interventional needle biopsy is greatly affected by the examiner, especially in the neck with dense blood vessels. Mistakes have serious consequences. Therefore, standardized training must be carried out before the operation to improve the success rate, accuracy and repeatability of the operation. Reduce clinical operation time.

Therefore, it is necessary to develop a model suitable for the practice of ultrasound interventional needle biopsy in the neck.
