Description

Neck puncture biopsy model

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a cervical puncture biopsy model.

Background

In the medical field, needle biopsy of cervical tumors is of great clinical importance for the selection of treatment regimens for cervical diseases. However, the anatomy of the neck is a relatively complex part of the human body, mainly due to the complexity of blood vessels, trachea and nerve wiring.

In actual clinical work, the puncture biopsy of neck viscera and pathological changes is an important component of interventional ultrasound teaching, and when a tumor grows on the neck, the tumor can be accurately determined through ultrasound examination and the puncture biopsy. However, before actual clinical work, a young interventional sonographer needs to practice operations by simulating neck lesions and organs in a simulated state to grasp correct operation techniques of ultrasonic intervention, and there is no teaching aid for practicing ultrasonic intervention neck tumors in the prior art.

The ultrasonic interventional puncture biopsy is greatly influenced by an examinee, particularly on the neck with densely distributed blood vessels, and has serious error consequences, so that standard training is required before operation, the success rate, accuracy and repeatability of operation are improved, and the clinical operation time is shortened.

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

Detailed Description

Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

As shown in fig. 1-3, a cervical biopsy model includes: an embedded phantom 1, a vascular phantom 2, a thyroid phantom 3, and at least one tumor phantom 4. The following details:

the outer side of the embedding imitation body 1 is sleeved with an imitation puncture outer skin, and the inner side is fixedly provided with a blood vessel imitation body 2, a thyroid imitation body 3 and a tumor imitation body 4. The blood vessel imitation 2 is a hollow structure or a solid structure, and the tumor imitation 4 is arranged inside and/or outside the thyroid imitation 3.

Further, the hardness of the blood vessel phantom 2 is less than that of the thyroid phantom 3, the hardness of the thyroid phantom 3 is less than that of the embedded phantom 1, and the hardness of the embedded phantom 1 is less than that of the tumor phantom 4.
