Description

Technical Field

[0001] The present invention relates to the technical field of thoracic surgery equipment, in particular to a puncture device for thoracic surgery. Background Art

[0002] Thoracic surgery is a branch of medicine that specializes in the study and treatment of diseases of organs within the chest cavity, including the lungs, esophagus, mediastinum, and pleura. In the process of thoracic surgery, puncture technology is a commonly used diagnostic and treatment method. The puncture device allows the doctor to enter the chest cavity through the skin puncture in order to extract tissue samples, drain pleural effusions, or inject drugs into the chest cavity. For example, thoracentesis is a common thoracic surgery operation used to drain fluid or air accumulation in the chest cavity, relieve pressure on the lungs or large blood vessels, and improve respiratory or circulatory function. During puncture treatment, the doctor will use a specific puncture needle to enter the pleural cavity through the rib space of the chest wall to extract fluid or gas.

[0003] However, existing puncture equipment has some limitations during operation. Medical staff need to monitor the puncture process in real time, and once the effusion is sucked out, the equipment must be turned off immediately to prevent air backflow, which not only increases the workload of medical staff, but also affects the patient's treatment experience.

[0004] In addition, the effusion in the pleural cavity may contain blood clots or other impurities, which may block the pipes of the device during the suction process. Once a blockage occurs, medical staff need to dismantle the equipment for cleaning, which is not only time-consuming and labor-intensive, but also requires the patient to be punctured again after cleaning, which undoubtedly increases the patient's discomfort and pain. Therefore, the existing puncture equipment needs to be improved in terms of convenience and patient comfort.

[0005] In view of the above problems, it is urgently necessary to carry out innovative design based on the original puncture device. Summary of the invention

[0025] Working principle: According to Figure 1 As shown, first, the gantry 1 is fixed to the bedside through the clamping structure 2, and the electric telescopic rod 3 is started to push the bearing plate 4 downward, so that the puncture needle 7 is inserted into the patient's chest cavity, and the device is started to generate suction force to collect the effusion in the chest cavity, and it is transported to the collection container through the inner tube 802. When it encounters blockage, the cleaning liquid is injected into the outer tube 801 of the delivery tube 8. The cleaning liquid passes through the opening 803 and pushes the baffle 804 into the inner tube 802 to flush and clear the blocked area of ​​the inner tube 802. Since the baffle 804 is opened toward The setting makes it possible for the inner tube 802 to not push the baffle 804 to open and enter the outer tube 801 when sucking the accumulated fluid. Through the setting of the trigger structure, with continuous suction, when the accumulated fluid becomes less, the accumulated fluid entering the inner tube 802 becomes less, and after passing through the box body 9, the trigger block 1002 cannot be effectively pushed, which will cause the trigger block 1002 to be out of contact with the travel switch. The travel switch sends a signal to the PLC control board, indicating that the accumulated fluid in the chest cavity is reduced, causing the equipment to reduce the suction force. This is the working principle of the puncture device for thoracic surgery.
