This application discloses a dental cleaning treatment method and system based on a magnetic particle cluster control device, relating to the field of dental caries prevention and treatment. The method includes: performing a three-dimensional scan of the oral cavity using a scanning magnetic control unit to construct a structural model; locating plaque distribution using image recognition technology to generate an oral cavity model containing plaque information; planning a cleaning path and formulating corresponding strategies based on the model; controlling the cleaning of magnetic particle clusters; monitoring plaque removal and changes in the oral microenvironment in real time; dynamically adjusting the cleaning path to ensure thorough cleaning; and safely recovering the plaque outside the oral cavity through an enrichment pump unit. This application reduces the difficulty of path planning and improves the targeting of oral cleaning by using a personalized modeling-based path planning method; it can dynamically adjust in real time according to changes in plaque distribution and the dynamic oral microenvironment, improving cleanliness and adaptability; the enrichment-then-pump recovery method improves recovery efficiency and enhances the safety and controllability of the treatment process.

A micron-sized mist dental cleaning device includes a console that generates pressurized air and pressurized water. The console is connected to a mouth guard that is in the form of an outer ridge and an inner ridge with a space between them for a patient's teeth. The mouth guard includes a receiver for receiving the pressurized air and water and has tubes for dispensing the pressurized air and pressurized water along the outer ridge and the inner ridge, respectively. The mouth guard also includes openings along the inner side of the outer ridge and the outer side of the inner ridge that face the location of the patient's teeth when the mouth guard is installed in the patient's mouth. The tubes for the pressurized air and water intersect at an angle at each opening so that they are used to eject micron-sized mist from the openings toward the user's teeth to provide initial plaque removal.

The present invention is a micro probe for plaque removal. In particular, the present invention is directed to a micro probe having a needle tip, an opening and perimeter openings for plaque removal. The micro probe is attached to a guide wire in a catheter and the catheter is attached to a pump. The needle tip is at the first end and the second end is attached to the guide wire and is insertable and retractable into the catheter. Each perimeter opening has a sharp edge and a blunt opposite edge and the micro probe can be rotated by the guide wire. The opening can also contain a dry ice pellet that can be impelled by the pump, or the pump can impel a solution through the catheter to the micro probe and aspirate the solution from the opening of the microprobe.

This disclosure provides a toothbrush head and a toothbrush with improved toothbrush bristle configuration comprising different types of bristle filaments in a specified arrangement. Disclosed are toothbrush heads comprising first tufts (5) comprising first bristles (6) and second tufts (7) comprising second bristles (8), wherein the second tufts (7) are positioned outermost closest to the distal end (3A) and outermost closest to the proximal end (3B) on the bristle surface (3), and / or outermost closest to the widthways opposite ends (3C, 3D) on the bristle surface (3), and wherein the second bristles (8) have a stem (19) that splits into split ends (21), and wherein the split ends (21) are chemically tapered. Also provided are toothbrushes comprising said toothbrush heads. The toothbrushes achieve excellent brushing performance, plaque removal from the gingival and subgingival margin and reach into the interproximal spaces. There are also disclosed methods of manufacturing these toothbrushes.

The invention discloses a coronary artery calcified plaque removing device capable of active rotary cutting and synchronous suction, and relates to the technical field of medical instruments.The coronary artery calcified plaque removing device comprises a machine body shell, an elastic pipe is fixedly connected to one end of the outer side of the machine body shell, and a drill bit is fixedly connected to one end of the elastic pipe; a transmission assembly and a cutter assembly are arranged between the drill bit and the transmission pipe fitting, a plurality of drainage key grooves are formed in the cutter assembly and formed in the outer side of the transmission pipe fitting, liquid is mixed with plaques cut down and smashed by the cutter assembly through rotation of the transmission pipe fitting, and the plaques form mixed liquid with good fluidity. The mixed liquid is good in flowability, the sewage pump pumps the mixed liquid through the first water guide piece, the multiple water guide holes and the suction pipe, due to the fact that the mixed liquid is good in flowability, the negative pressure needed for pumping the mixed liquid is low, it is guaranteed that plaques cleaned through cooperation of the cutter assembly and the drill bit are pumped out, and meanwhile blood vessel deformation caused by the negative pressure is avoided; and the possibility of injury of the cutter assembly to blood vessels is reduced.

A plaque removal system includes an electrically driven mechanism adapted to rotatably actuate a plaque removal burr head; and a controller adapted to regulate the operation of the electrically driven mechanism. The controller regulates the operation of the electrically driven mechanism based on power input limits limiting how much power can be delivered to the plaque removal burr head and energy input limits limiting how much energy can be delivered to the plaque removal burr head. The controller can also regulate the operation of the electrically driven mechanism based on dynamic torque limits.
