Torque wrench for assembling and disassembling working tip of ultrasonic tooth cleaning equipment

Abstract

The invention relates to a torque wrench for assembling and disassembling a working tip of ultrasonic tooth cleaning equipment. The torque wrench comprises a wrench shell inner lining, a resistance elastic part and a clamping assembly; the lining is arranged in the wrench shell; a through hole is formed in the top surface of the lining; the resistance elastic part is a spring, and the spring is arranged on the lining in a sleeving mode and is used for providing the elastic force to force the lining to rotate around the axis of a channel relative to the wrench shell; and the clamping assembly comprises a clamping part and a clamping frame, wherein the clamping part and the clamping frame are stacked up and down, the clamping part is arranged on the clamping frame, and the clamping part and the clamping frame act together to clamp the working tip. The torque wrench has the beneficial effects that the clamping assembly can be tightly matched with a step part of the working tip, the working tip can be picked and placed by utilizing the wrench, hands are not required to make direct contact with the working tip in the whole process, and therefore cleanness and sanitation in the medical process can be guaranteed, and cross contamination can be avoided; and the resistance elastic part enables the working tip to be screwed in place, and therefore the over-tightening and over-loose phenomena of the working tip can be avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a force-limiting wrench for loading and unloading working tips of ultrasonic tooth cleaning equipment Background technique [0002] The oral cavity is the first channel for food to enter the human body. Many foreign studies have shown that the quality of the teeth is closely related to the health of the whole body. Statistics show that the current situation of oral health problems in my country is worrying, and about 80% of people are facing dental infestation, which needs to be paid attention to urgently. According to the data of the third "National Oral Health Epidemiological Survey", 80%-97% of adults in my country have different degrees of periodontal problems, and among people aged 35-44, the proportion of gingival bleeding is as high as 77.3%. [0003] Some advanced hospitals use ultrasonic scalers when cleaning patients' teeth. The structure of the ultrasonic scaler is d...
