Problems solved by technology

A multifunctional puncture device for cardiothoracic surgery in the above patent. The whole process of thoracentesis is operated by a mechanical device, but the operation of the mechanical device cannot sense the breakthrough of the puncture needle through the skin. When the puncture needle is inserted too shallow, the chest cavity cannot be extracted. Effusion, puncture too deep will damage lung tissue

Abstract

The invention discloses a multifunctional positioning puncture device for cardiothoracic surgery, and relates to the technical field of medical instruments. The problem that positioning puncture of a thoracic cavity needs to be cooperatively operated by two persons and cannot be independently operated is solved. The device specifically comprises a supporting base plate, an arc-shaped supporting column, a fixing connecting column and a silicone tube; a first protection pad is arranged on the outer wall of one side of the supporting base plate; wool fabric burrs are arranged on the inner wall of one side of the first protection pad; a second protection pad is arranged on the outer wall of the other side of the supporting base plate; and woolen felt is arranged on the outer wall of one side of the second protection pad. The device can be arranged on a patient in a sleeving mode through the wool fabric burrs on the first protection pad and the woolen felt on the second protection pad, so that a puncture hole in the supporting base plate is conveniently fixed, the stability of the device is improved, the accuracy is improved when a paracentesis is conducted on the patient through the puncture hole in the follow-up process, the vacant side of the arc-shaped supporting column is convenient for medical personnel to carry out the paracentesis, so that the paracentesis effect is better.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional positioning puncture device for cardiothoracic surgery. Background technique [0002] When performing thoracentesis, it is necessary to fix the punctured skin at the puncture site. The puncture needle is inserted vertically and slowly at the puncture point. When the puncture needle feels a breakthrough, it indicates that it has entered the pleural cavity. At present, in the prior art, thoracentesis requires two people to cooperate and cannot be operated by a doctor alone, which is a waste of manpower and poor puncture effect due to poor coordination between two people. Therefore, there is an urgent need for a chest puncture Multifunctional positioning puncture device for surgery. [0003] After retrieval, the Chinese patent application number is CN202020278513.X, which discloses a multi-functional cardiothoracic surgery puncture device, which relate...
