Puncture outfit for cardio-thoracic surgical operation

Abstract

The invention discloses a puncture outfit for a cardio-thoracic surgical operation. The puncture outfit structurally comprises a puncture needle, an antiskid thread, a gas injection valve, a puncture sleeve, a puncture cone, a sealing cap, a sleeve and a locating device. According to the puncture outfit, during use after improvement, a sealing guard plate is tightly attached to a skin incision of a sufferer, a certain gap possibly generated between the puncture sleeve and the incision is effectively reduced, outside air will be blocked, then, sucking sheets are parallelly attached to the two sides of the incision of the sufferer, a position of the puncture sleeve is effectively located, thus, the puncture sleeve can be free of sloshing after the puncture cone is withdrawn, internal organs of the sufferer are protected effectively, and the puncture effect is improved.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a puncture device for cardiothoracic surgery. Background technique [0002] Cardiothoracic surgery includes diseases of cardiac surgery and general thoracic surgery. In cardiothoracic surgery, puncture technology is used. Puncture is to insert a puncture needle into the body cavity to extract secretions for testing, and inject gas or contrast agent into the body cavity for contrast examination. Therefore, the puncture device for cardiothoracic surgery is relatively common in medical treatment. The position of the puncture device is restricted and positioned by the positioning element to ensure that hard injuries can accurately extract effusions from the patient's heart and chest. When puncturing a patient, improvements need to be made: [0003] When puncturing a patient, the doctor inserts the puncture cannula into the skin incision. Since the puncture cone is set inside the punc...

Problems solved by technology

[0003] When puncturing a patient, the doctor inserts the puncture cannula into the skin incision. Since the puncture cone is set inside the puncture cannula, the doctor needs to press the puncture cannula with one hand and pull out the puncture cone with the other hand. During the process, the puncture cannula will move upwards with the puncture cone under the action of the puncture cone, so that there will be a certain gap between the puncture cannula and the incision, so that the external air will flow into the patient's body through the incision, increasing the The pain of the patient is reduced, and when the puncture cone is pulled out, the puncture cannula will vibrate to a certain extent due to the pulling force, causing the puncture cannula to shake slightly in the patient's body, which is easy to hurt the patient's internal organs, causing secondary trauma in the patient's body.
