Abstract

The invention discloses a fluid-assisted visual bipolar electric coagulation hemostasis device which comprises an outer sleeve, a sleeve base, a rod body, bipolar electric coagulation forceps and an imaging module, the front end of the sleeve base is fixedly connected with the rear end of the outer sleeve, and a sealing connector is arranged at the rear end of the sleeve base. The rod body is arranged on the inner side of the outer sleeve, a lens of the imaging module is fixed to the front end of the rod body, and a clear water cavity is formed between the front end face of the outer sleeve and the lens. The rod body is in sliding sealing fit with the rear end of the sleeve base. The bipolar electric coagulation forceps comprise two electrode forceps heads symmetrically arranged on the two sides of the rod body, the front ends of the electrode forceps heads extend out of the outer sleeve, and when the rod body moves forwards, the two electrode forceps heads are in sliding fit with the inner wall of the outer sleeve. The lens of the imaging module is located on the rear side of the front end face of the outer sleeve, a section of clear water cavity is formed in the front portion of the outer sleeve, liquid flowing forwards in the clear water cavity provides clear and visible observation conditions, the bleeding part is rapidly and accurately judged, the operation accuracy and efficiency are improved, and the possibility of misoperation is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fluid-assisted visual bipolar electrocoagulation hemostasis device. Background technique [0002] The bipolar electrocoagulation hemostasis device is a commonly used operating instrument in the field of neurosurgery, and its main form is the bipolar electrocoagulation forceps that can be energized. The existing bipolar electrocoagulation forceps are usually large in size and cannot be operated in a small channel. There are also bipolar electric coagulation forceps installed in the cavity of the puncture cannula, which can be used together with the endoscope installed in the puncture cannula to achieve visual operation inside the wound. Neither the speculum can achieve clear and visual observation of the bleeding site on the tissue surface. At the moment when electrocoagulation is most needed, bipolar coagulation forceps cannot effectively stop bleeding at the bleeding s...
