Puncture and aspiration system for thoracic surgery department

Abstract

The invention discloses a puncture and aspiration system for a thoracic surgery department. The puncture and aspiration system comprises a bed board. Rollers are arranged at the bottom of the bed board. A through hole is formed in the bed board, a lifting electric stretchable rod running through the through hole is arrange below the bed board through a support, a fixing rod is arranged on the lifting electric stretchable rod, an arm supporting plate is arranged on the fixing rod, a sliding groove is formed in the fixing rod, a chest electric stretchable rod sliding up and down is arranged inside the sliding groove, a cushion block for supporting the chest is arranged on the chest electric stretchable rod, and a first electric stretchable rod driving the chest electric stretchable rod to move up and down is arranged below the arm supporting plate. The system can relieve the tired feeling of a patient, and the patient feels comfortable when rested on a base plate.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection of surgical instruments, in particular to a puncture and pumping system for thoracic surgery. Background technique [0002] Interventional ultrasound is a minimally invasive technique that is increasingly used clinically. The existing ultrasound diagnostic bed is prone to stiff posture and discomfort. Ultrasound diagnostic rooms generally need to be dark, which is not conducive to puncture to expose the surgical site, and turning on the lights will affect the effect of ultrasound images; it is not conducive to doctors to operate during puncture and drainage. [0003] When a weak patient performs thoracentesis according to the doctor's guidance angle, the patient needs to fix the position for a long time. Such patients are generally in serious condition and weak. And grasp the angle. Sometimes a pillow is added to the back of the patient to maintain the position, and it is not easy t...

Problems solved by technology

[0005] At the same time, it is difficult to accurately grasp the puncture depth with existing puncture needles, and it is often necessary to insert and withdraw the syringe multiple times until the liquid is drawn out, which often requires at least two people to operate

In addition, when the fluid in the pleural cavity is pumped less and less, the visceral pleura is getting closer to the parietal pleura. If the operator wants to extract as much fluid as possible, he often needs to change the position of the puncture needle, which makes it easier to cause damage to the visceral pleura and internal organs.

If the amount of effusion in the patient's pleural cavity is small, the puncture point is lower or the puncture site is close to important organs or blood vessels, it is more likely to cause injury
