Description

A kind of auxiliary training device for liver puncture operation

Technical field

The invention belongs to the technical field of medical devices, and specifically relates to an auxiliary training device for liver puncture operations.

Background technique

Liver puncture refers to a diagnostic and treatment technology that uses skin puncture under the guidance of ultrasound or CT, or direct puncture under laparoscopy to obtain living liver tissue for histological examination or cytological examination. It mainly includes liver biopsy puncture and liver abscess puncture, which can not only diagnose liver diseases that cannot be clearly diagnosed by laboratory and other auxiliary examinations, but can also be used to extract pus to treat liver abscesses, etc. Liver puncture generally inserts the needle from the right side of the chest, through the epidermis, subcutaneous tissue, and ribs to reach the liver.

Before entering the clinic for actual liver puncture, long-term operational training is required to improve puncture experience and skills. Puncture training is generally performed on a model, but the currently used liver puncture training model still has the following shortcomings: 1) The model is just an exposed liver model, and training is performed on it, but the actual liver is located in the right upper abdomen, and liver puncture training is performed on it. Puncture has to go through skin, fat, muscle and other tissues and needs to avoid the ribs to reach the liver, so the current model cannot train how to grasp the angle and direction of the needle when inserting the needle; 2) The needle feel of the needle is also very important during the puncture process Different tissue parts receive different resistance when inserting the needle, so a simple model of rubber or other materials cannot simulate the puncture needle feel of a real liver, and the puncture needle difference between a healthy liver and a cirrhotic liver The feeling is also different; 3) For liver cyst puncture, the location of the cyst needs to be determined under medical imaging, and then the emergency angle direction is determined. Then during puncture training, timely feedback is required on whether the puncture position has been punctured before it can be performed during training. Error adjustment.
