Percutaneous Nephrocentesis Positioner

Abstract

The invention discloses a percutaneous nephrolithotomy locator, and relates to the technical field of medical apparatus and instruments. The locator comprises a bottom plate base matched with a bed in a sliding mode, a locating mechanism is connected to the right end of a locating rod and comprises a vertical frame, a horizontal frame and a puncture device, a servo motor A is installed at the right end of the locating rod, the output end of the servo motor A is connected with the upper end of the vertical frame, and the puncture device comprises a shell; the output end of a servo motor C is connected wit,h the side face of the shell, a control pipe is fixedly connected into a through hole, and a hoop pipe is connected with a puncture needle in a locked mode. The percutaneous nephrolithotomy locator has the advantages that an existing breathing detection technology is combined to serve as an input parameter of the scheme, the puncture position is adjusted by means of three degrees of freedom, active locating and automatic puncture are achieved, in the puncture process, the puncture needle can rotate, the puncture efficiency is improved, operation is easy, and the locator is safe and effective.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] Usually, puncture is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for laboratory tests, gas or contrast agent is injected into the body cavity for contrast examination, or a positioning guide wire is inserted into the body cavity, or drugs are injected into the body cavity. The puncture has high requirements. The operation should be careful, serious and fast, and the time should be shortened as much as possible. The patient should cooperate closely and strictly follow the requirements to keep the breathing steady and not cough. puncture success rate. However, in the actual operation, because the patient cannot keep breathing well, it makes it difficult for the doctor to find the lesion, which reduces the success rate of puncture, which increases the pain and psychological pressure o...

Problems solved by technology

However, in the actual operation, because the patient cannot keep breathing well, it is difficult for the doctor to find the focus point, which reduces the success rate of puncture, which increases the pain and psychological pressure of the patient.

The patent application publication number is CN 104510476 A, which discloses a puncture-specific monitor with respiratory gating, which can detect respiratory signals. However, medical personnel need to manually locate and puncture according to the signal prompts, which is likely to cause errors and cannot be used reasonably and effectively. time
