Saliva suction tube capable of movably adjusting filter screen

Abstract

The invention provides a saliva suction tube capable of movably adjusting a filter screen. The bottom side wall of the saliva suction tube is provided with a linear opening which is far from the suction end, the inside of the saliva suction tube is movably provided with a filter screen assembly at the position of the opening, the filter screen assembly comprises a sliding rod and a filter screen arranged on the top of the sliding rod, the side surface of the sliding rod is provided with a button, the button protrudes out of the opening and is in interference fit with the opening, and both thelength and the width of the sliding rod are larger than the size of the opening; and the interior edge of the saliva suction tube is provided with a circle of limiting ring which is close to the length direction of the opening. The saliva suction tube is suitable for all oral surgery, and other mucogingival surgery and bone grafting surgery which are more difficult and demanding. The saliva suction tube not only can suck and remove oozing blood, saliva and scraped granulation tissue generated in the operation in time, but also can adjust the filter screen according to different types and different operation stages of the operation, thereby avoiding waste and cost increasing caused by aspiration and wrong-suction, and further making the operation process safer and more efficient.

Description

technical field [0001] The invention belongs to the oral cavity field, and in particular relates to a saliva suction tube with a movable adjustable filter screen. Background technique [0002] During all oral operations, a saliva suction tube is needed to assist in suction during the operation, and to suck out some blood, saliva and scraped granulation tissue during the operation. At present, the saliva suction tube used clinically in surgery is a simple one-piece metal saliva suction tube. This saliva suction tube has no problem in attracting saliva and blood, but it needs to be implanted in some complex operations such as bone grafting. When the periosteum is used, it is easy to suck away the periosteum by mistake, resulting in waste and increased cost; in addition, in membrane and gingival surgery, if the gingival flap is not sucked, bleeding and blurred vision will occur. The valve is sucked away by mistake, causing loss and suffering to the patient. [0003] In view o...
