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

Embodiment 1

[0036]As shown in the figure: a multifunctional head, including an annular body 8-1, the front face of the annular body 8-1 has 6 grooves evenly distributed along its circumferential direction, and 3 sound sources are arranged at intervals in the 6 grooves Part 8-2 and the first suction head 8-3, the sound frequency of the sound source part 8-2 is 2-3kHz, and the suction head 8-3 is connected with the negative pressure suction source through a pipeline.

[0037] The multifunctional head 8 is an auxiliary accessory for increasing the function of the hemostat, and has the functions of sound wave emission and smoke suction. While the electrocoagulation operation is in progress, the sound source on the multifunctional head emits sound waves with a frequency of 2-3kHz. Through the agglomeration mechanism of the sound waves, the smoke generated during the electrocoagulation operation is reunited at the beginning of appearance, reducing the The formation scale of the smoke avoids the...

Embodiment 2

[0039] As shown in the figure: an electrocoagulation hemostat for hepatobiliary surgery, including an insulating outer sleeve 5, a conductive rod 6, a scraping electrocoagulation head and the multifunctional head in Example 1, through which the scraping electrocoagulation head is screwed The upper part is arranged on the head end of the insulating outer casing 5, and the conductive rod 6 is penetrated in the insulating outer casing 5. The head end of the conductive rod 6 is connected with the electrocoagulation rod 1 of the electrocoagulation head, and the tail end of the conductive rod 6 is connected with the power supply. Connected, the conductive rod 6 can move along the axis in the insulating outer sleeve 5, and then drive the electrocoagulation rod 1 to extend or retract inside the reducing head 2, and the multifunctional head 8 is sleeved on the head end of the insulating outer sleeve 5.

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...
