Biopsy puncture auxiliary locator

Abstract

The invention relates to a biopsy puncture auxiliary locator. The biopsy puncture auxiliary locator is characterized by comprising base plates which are matched with each other, a fixing plate, a locating pin reference plate, a rotating arm, a rotating sliding block, a sliding block gland and a guide pipe. The locating pin reference plate is arranged on the fixing plate, the base plates are magnetically connected to the locating pin reference plate, the rotating arm can rotate around the base plates, and the guide pipe is matched with the rotating sliding block and the sliding block gland and arranged on the rotating arm in a sliding mode. According to the biopsy puncture auxiliary locator, a doctor can perform a puncture operation fast and accurately, accuracy and stability are high, CT scanning is not needed again even if the body position of a patient moves inadvertently after location is finished, the locating position can be recovered just by overlapping an infrared reference line on the biopsy puncture auxiliary locator and CT infrared rays, repeated CT scanning and progressive needle insertion of a traditional puncture operation are avoided, operation safety is improved, operation time is shortened, radiation exposure caused by repeated roentgenoscopy is reduced, and tissue trauma and complications are reduced.

Description

technical field [0001] The invention relates to a biopsy puncture auxiliary positioning instrument. Background technique [0002] CT-guided puncture surgery is now widely used in clinical practice. Doctors use the traditional method of manual puncture based on CT medical images. This method requires repeated scanning and progressive puncture for puncture operations with relatively small lesions, which takes a long time and has low accuracy. [0003] In the prior art, the puncture method based on three-dimensional reconstruction has high requirements for medical equipment, increases the operation time, and the positioning operation must be in an ideal state to meet the accuracy requirements, and does not change the situation of repeated scanning and multiple needle insertions; based on tomography The traditional puncture method can only be positioned accurately when the skin surface where the needle is inserted is perpendicular to the scanning section, which puts forw...

[0002] CT-guided puncture surgery is now widely used in clinical practice. Doctors use the traditional method of manual puncture based on CT medical images. This method requires repeated scanning and progressive puncture for puncture surgery with relatively small lesions, which takes a long time and has low accuracy.

[0003] In the prior art, the puncture method based on three-dimensional reconstruction has high requirements for medical equipment, increases the operation time, and the positioning operation must be in an ideal state to meet the accuracy requirements, and does not change the situation of repeated scanning and multiple needle insertions; based on tomography The puncture method of this method requires accurate positioning when the skin surface where the needle is inserted is perpendicular to the scanning section, which puts forward higher requirements for the patient's position and requires the human skin surface to be flat, and the applicable range is very small
