Multifunctional head and multi-mode electrocoagulation hemostat for hepatobiliary surgery

Abstract

The invention discloses a multifunctional head and a multi-mode electrocoagulation hemostat for hepatobiliary surgery. The multifunctional head comprises an annular body, N grooves are evenly distributed in the front end face of the annular body in the circumferential direction of the annular body, sound source parts and suction heads are arranged in the N grooves at intervals, the suction heads are connected with a negative pressure suction source through a pipeline; and the electrocoagulation hemostat for the hepatobiliary surgery comprises an insulating outer sleeve, a conducting rod, a scab-scraping electrocoagulation head and the multifunctional head, the scab-scraping electrocoagulation head is arranged at the head end of the insulating outer sleeve through a rotary connecting part of the scab-scraping electrocoagulation head, the conducting rod is arranged in the insulating outer sleeve in a penetrating mode, the head end of the conducting rod is connected with an electrocoagulation rod of the electrocoagulation head, the tail end of the conducting rod is connected with a power supply, the conducting rod can move in the insulating outer sleeve along the axis so as to drive the electrocoagulation rod to stretch out of or retract into a reducing head, and the multifunctional head is arranged at the head end of the insulating outer sleeve in a sleeving mode. The electrocoagulation hemostat has the functions of scab scraping, smoke suction and the like, and can provide a high-quality hemostasis effect for the hepatobiliary surgery.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a multi-functional head and a multi-mode electrocoagulation hemostasis device for hepatobiliary surgery. Background technique [0002] Clinically, when performing hepatobiliary surgery on a patient, the wound needs to be hemostasis immediately after making an incision with a scalpel. Under normal circumstances, the bleeding caused by damage to small blood vessels will stop within a few minutes. This phenomenon is called Physiological hemostasis is one of the important protective mechanisms of the body and is the result of the interaction of various factors and mechanisms. At present, the commonly used method of hemostasis is electrocoagulation. When the surgical field of view is large, the use of electrocoagulation has the advantages of simple operation, time saving, and economy. However, electrocoagulation will generate a lot of smoke during the operation. I...

Problems solved by technology

At present, the commonly used method of hemostasis is electrocoagulation. When the surgical field of view is large, the use of electrocoagulation has the advantages of simple operation, time saving, and economy. However, electrocoagulation will generate a lot of smoke during the operation. It will lead to blurring of the surgical field of view and prolong the operation time. However, the existing hemostatic device for hepatobiliary surgery cannot quickly replace the hemostatic method suitable for different surgical fields of view according to different surgical fields of view.

In addition, when using electrocoagulation to stop bleeding, the electrocoagulation hemostasis probe often has many blood scabs stuck to it, while the hemostat in the prior art does not have a blood scab erasing structure, which is inconvenient to use, and the blood scab adheres to the electrocoagulation hemostasis probe It will affect the hemostatic effect of the electrocoagulation hemostatic probe
