Hollow vector support multifunctional protection device for minimally invasive surgery

Abstract

The invention provides a hollow vector support multifunctional protection device for a minimally invasive surgery, which can be applied to minimally invasive surgeries of the oral cavity, pharynx andthroat, digestive tract, respiratory tract, thoracic cavity, abdominal cavity and other cavities. A flap on a protective head of the protection device can be used for protecting an operation area by adjusting an opening degree through an axial movement mechanism of an inner cylinder, and the size of the operation area can be freely adjusted; and the protective head can also be rotated outwards through a pitching mechanism of the protective head to increase an operation visual field, so that vector adjustment of the protective head and the flap is achieved, and the direction, force and size ofthe protective head and the flap can be adjusted as required. The hollow vector support multifunctional protection device is also provided with a gas fluid transfusion and delivery passage and an illumination device on the flap, so that the integration of multiple functions of illumination, flushing, drug administration, cleaning, disinfection, hemostasis, provision of support channels for surgical tools such as a laser scalpel and the like is achieved; and by covering the part between the protective head and a shell and/or between a plurality of flaps with an elastic membrane and the like, the wound of the operation area is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a hollow vector support multifunctional protection device for minimally invasive surgery. Background technique [0002] According to literature reports, in recent years, the incidence of intestinal diseases has increased year by year, especially malignant lesions, which will invade, compress and even obstruct the narrow part of the intestinal tract, causing difficulties in food digestion and absorption and defecation, seriously affecting people's lives. and quality of life. There are about 1 million new cases of intestinal malignant lesions in the world every year, and 7% to 29% of the patients present as acute complete or incomplete intestinal obstruction as the first symptom. Due to intestinal obstruction, especially colorectal obstruction, preoperative intestinal preparation cannot be performed, and clinical treatment is difficult. Postoperative complications such as anastomo...
