Puncture device for thoracic surgery department

Abstract

The invention discloses a puncture device for the thoracic surgery department. The puncture device comprises a disinfection tube; the left side end face of the disinfection tube is fixedly connected with a threaded connection tube; the outer side wall of the threaded connection tube is in threaded connection with a rotary blind tube; a positioning mechanism used for anesthetizing and positioning a puncture part of a patient is arranged in the rotary blind tube; and a sterilization tube is clamped on the right side wall of the disinfection tube. By arranging the rotary blind tube, attaching blocks, movable rods, gear rings and other structures, the gear rings are driven by rotation of the rotary blind tube to drive driving gears to rotate, meanwhile, contact driving between wedging blocks and corresponding wedging grooves in a rotating tube is matched, rotary stretching and retracting of the movable rods are achieved, and stretching and retracting of each anesthetic needle are achieved; and local anesthesia can be conveniently carried out on the patient, the puncture part can be positioned, and the disinfection tube, the sterilization tube, an observation tube and other structures are arranged and are clamped and fixed, so that disposable consumables in the disinfection tube, the sterilization tube and the observation tube can be conveniently replaced, and the interiors can be conveniently cleaned.

Description

technical field [0001] The invention relates to the technical field of surgery and medical treatment, in particular to a puncture device for thoracic surgery. Background technique [0002] Puncture, a term commonly used in medical surgery, is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is blood test, blood transfusion, infusion and catheter placement for angiography, etc. [0003] Thoracic surgery puncture is to extract the pleural effusion of patients through puncture. The existing thoracic surgery puncture equipment needs to be disinfected before and after use, and most of them are treated by high temperature sterilization. When using this method, The sterilization efficiency is low, and the operation is more complicated, and the puncture needle i...

Problems solved by technology

[0003] Thoracic surgery puncture is to extract the pleural effusion of patients through puncture. The existing thoracic surgery puncture equipment needs to be disinfected before and after use, and most of them are treated by high temperature sterilization. When using this method, The sterilization efficiency is low, and the operation is more complicated, and the puncture needle is prone to re-contamination when it is exposed to the air during operation. The puncture site needs to be positioned and marked, which requires high puncture accuracy
