Negative-pressure adsorption mechanism with rotary inner tube and bipolar electrocoagulator using negative-pressure adsorption mechanism

Abstract

The invention discloses a negative-pressure adsorption mechanism with a rotary inner tube and a bipolar electrocoagulator using the negative-pressure adsorption mechanism. The negative-pressure adsorption mechanism comprises a negative-pressure adsorption tube, a rotary driving assembly and a negative-pressure communication tube. The negative-pressure adsorption tube is provided with an adsorptionpassage which is hollow in the axial direction. The rotary driving assembly comprises a rotating rod connected with one end of the negative-pressure adsorption tube, a deceleration energy storage unit connected with the rotating rod to be suitable for driving the rotating rod to rotate, and a negative-pressure pump connected with the deceleration energy storage unit; the rotating rod is suitablefor driving the negative-pressure adsorption tube to rotate; the negative-pressure communication tube communicates with the side wall of the end part, connected with the rotating rod, of the negative-pressure adsorption tube; and the negative-pressure pump and the negative-pressure communication tube are connected with a negative-pressure adapting tube through the same negative-pressure distribution structure. The bipolar electrocoagulator can perform negative-pressure adsorption on foreign matters such as blood clots, and can also effectively prevent the blood clots or the foreign matters from blocking the negative-pressure adsorption tube.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a negative pressure adsorption mechanism with a rotating inner tube and a bipolar electrocoagulator using the same. Background technique [0002] Bipolar coagulation for hemostasis and bipolar plasma ablation are commonly used methods in current surgery. For example, in the minimally invasive surgery for hemostasis of cerebral hemorrhage, bipolar coagulation can be used to quickly and locally seal blood vessels for bleeding points, while for cerebral hemorrhage Blood clots or other foreign bodies that have solidified inside need to be quickly removed by negative pressure adsorption; another example is the use of bipolar plasma ablation electrodes to gasify and decompose aging tissues inside the intervertebral disc in minimally invasive cervical and lumbar surgery, reducing Pressure, thereby reducing the compression and stimulation of the intervertebral disc tissue on ...
