Water-dropping bipolar coagulation aspirator

Abstract

The invention relates to a water-dropping bipolar coagulation aspirator and belongs to the technical field of surgical instruments, devices or methods. The water-dropping bipolar coagulation aspiratorcomprises a holding piece, an aspiration joint, an electrode tube, a pressure regulating mechanism, a flushing tube and an aspirating tube, wherein the aspiration joint and the aspirating tube are respectively arranged at two ends of the holding piece; one end of the aspirating tube extends into the holding piece and is communicated with the aspiration joint in the holding piece; a positive electrode needle and a negative electrode needle are arranged at the other end of the aspirating tube and respectively connected with a positive pole and a negative pole of the electrode tube so as to achieve a coagulation effect; the pressure regulating mechanism is arranged on the upper part of the holding piece and extends downwards to be in contact connection with the aspirating tube so as to control the aspiration force of the aspirating tube; the electrode tube and the flushing tube are arranged on the holding piece, and an electrode tube hole is formed in the electrode tube; and the flushingtube is communicated with the aspirating tube at the end where the positive and negative electrode needles are positioned via the electrode tube hole. When being applied to a microscope, an endoscopeand other operations, the water-dropping bipolar coagulation aspirator disclosed by the invention has the advantages of convenience in aspiration force adjustment, one-appliance multi-purpose effectsand the like.

Description

technical field [0001] The application relates to a drip bipolar electrocoagulation aspirator, which belongs to the technical field of surgical instruments, devices or methods. Background technique [0002] With the development of science and technology, neuroendoscopic surgery, microneurosurgery and minimally invasive surgical treatment have been put on the agenda. The scope of cranial window and cerebral cortex incision is getting smaller and smaller, and the intracranial surgery site is getting deeper and deeper. In order to make the operative field clear, the surgeon needs to replace the aspirator, hemostatic coagulation forceps, and operative field irrigator more and more frequently, which seriously prolongs the operation time and increases the risk of the operation. Taking neuroendoscopic surgery as an example, the doctor usually holds an observation mirror in one hand and a suction device in the other. When he encounters intracerebral blood vessel bleeding, he must wi...

AI Technical Summary

Problems solved by technology

This device not only solves the three most necessary and basic functions in microscopic and endoscopic surgery: suction, electrocoagulation and hemostasis, and frequent replacement of surgical instruments caused by operative field washing, but also solves the problem of single suction, monopolar coagulation and bipolar Electrocoagulation and intraoperative water flushing can not achieve the effect, so that the operation field is clearer, the bleeding is less during operation, the operation time is shorter, and the risk during operation is significantly reduced
