Abstract

The invention belongs to the field of medical instruments and particularly relates to a homogenate aspirator for minimally invasive removal of sludged blood and a control method of the homogenate aspirator. The homogenate aspirator comprises a main operating rod, a homogenate cutter bit, a mesh cover, a soft endoscope, a handle, a mesh cover adjusting rod, a cutter bit switch, a mesh cover adjustor, a negative-pressure switch, a camera controller, a main switch, a power supply cavity, a negative-pressure suction tube, video equipment and a negative-pressure aspirator. By adoption of the homogenate aspirator, a traditional general anesthesia method can be replaced, and the problem of clearing of residual sludged blood in the thoracic cavity due to bleeding and drainage nonsmoothness of a patient suffering from traumas or subjected to cardiothoracic surgeries can be solved under local anaesthesia and minimally invasive conditions, so that an operating process of sludged blood clearing can be dramatically simplified, and safety is improved.

Description

Technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a homogenizer aspirator for minimally invasively removing blood clots and a control method thereof. technical background [0002] Patients after thoracic trauma and thoracic surgery are often bleeding and thoracic drainage is not smooth, resulting in residual and coagulation of blood in the thoracic cavity. The coagulated blood clot cannot be drained out of the body with a thoracic drainage tube. If it is left in the thoracic cavity without being removed, it will lead to secondary intrathoracic infection and even empyema. At present, thoracic surgery mainly adopts thoracotomy under general anesthesia to remove blood clots for patients with coagulative hemothorax, which is more traumatic and expensive. Under the minimally invasive local anesthesia, the safe removal of intrathoracic blood clots has always been a difficult problem to be solved urgently in clinical treatme...
