Description

CT-guided liver puncture inflatable inspiration depth controller

Technical Field

The utility model belongs to the technical field of medical auxiliary devices, and particularly relates to an inflatable inspiration depth controller for liver puncture guided by CT.

Background

Most hospitals will perform puncture pathology examinations as necessary depending on the patient's disease condition. At present, the conventional puncture navigation method determines the needle inserting angle and depth through a CT scanning image, generally determines a positioning point through a positioning grid, needs to perform blind puncture on a focus according to the experience of an operator, sometimes needs to repeatedly adjust the puncture angle, needs to repeatedly scan to confirm whether a puncture needle is in place, the focus is smaller or the position is deeper, the difficulty of puncture is correspondingly increased, the times of needle adjustment for puncture is possibly increased, the puncture time is prolonged, multiple times of puncture needle adjustment are needed, the risk of corresponding adverse reaction of puncture is increased, and the patient is also greatly damaged by radiation.

Usually, puncture the liver of a patient needs to obtain secondary pathological tissues, and in addition, because the suction depth of each patient is inconsistent, the puncture of a small focus is difficult to succeed. The reason that the success rate of the primary puncture of the small focus is low is that the size of the small focus is small, the difficulty of puncture is increased, and the small focus is more easily affected by respiratory movement, particularly when the focus is positioned near a diaphragm with larger mobility, the difficulty of puncture is obviously increased, and a slight angle error can cause the needle point to deviate from a target point; repeated punctures are a type of injury to the liver, such that bleeding from the puncture results in a failure to complete the puncture. Therefore, when the percutaneous puncture is conducted on the liver focus under the guidance of CT, the patient needs to be trained to breathe, in order to overcome the influence of breathing motion on the focus position, a breathing depth controller is also applied during the puncture, and the positioning and the puncture are always in the same breathing depth. The puncture needle has a certain positive effect on overcoming the respiratory influence, and if the puncture needle is parallel to the focus when the patient is positioned and punctured at the same respiratory depth all the time, the puncture path can be ensured to be accurate, the puncture success rate is improved, the puncture frequency is reduced, the damage to liver tissues is small, the generation of complications such as bleeding is reduced, the radiation dose is reduced, and the puncture accuracy is improved.
