Description

A safe root canal treatment system

technical field

The present invention relates to medical instruments, in particular to a safe root canal treatment system.

Background technique

Root canal therapy is currently an ideal and mature treatment for various diseases such as pulpitis and pulp necrosis. The main process is to use the root canal file to thoroughly clean the inside of the diseased root canal and the root canal wall, remove the diseased tissue, and shape a complete and smooth root canal cavity, complete the root canal preparation, and then insert the prepared root canal into the root canal. Filled with other materials to achieve the purpose of root canal repair and treatment.

At present, the commonly used root canal preparation methods are completed by the use of mechanical root canal instruments and root canal motors. When working, the root canal motor drives the machine to rotate with root canal instruments to clean and shape the inside of the root canal. Its advantages are high root canal forming efficiency, good forming effect, and greatly reduce the operator's work intensity.

Mechanical root canal instruments are divided into different models and specifications according to the size, taper, cross-sectional shape and material of the working part. In order to prevent the occurrence of medical accidents such as excessive deformation and twisting of the instruments in the root canal during work, different specifications of mechanical root canal instruments need to have their own working conditions, such as working speed, maximum allowable torque, rotation mode (continuous positive rotation, alternating forward and reverse, reverse after being blocked) and so on.

Since the mechanical instruments need to be used in conjunction with the root canal motor, there are clear and unified requirements for the structure and size of the handle of the instrument, and it is required to mark the specifications of the instrument in the form of a color ring on the handle. The requirements for the structure, size, and specification of the handle of the mechanical root canal instrument are clearly specified in the ISO-3620 (YY 0803) and ISO-197 (YY/T 0976) series of standards, as shown in Figure 1. At the rear end of the handle of the root canal instrument A-1, a platform A-2 is arranged, and its function is to cooperate with the platform on the inner drive shaft of the root canal motor to realize the transmission of torque; at the front end of the handle, a colored ring A-3 is arranged , used to identify the specifications of the device. However, the color of the color circle only represents the nominal diameter of the tip of the instrument. As for the taper change, cross-sectional structure and other information of the instrument, it cannot be fully expressed. For specific root canal instrument products, the manufacturer needs to provide special instructions for the operator to choose and use.

Regarding the design of the root canal motor system, there are mainly two forms at present. One is to install a power supply and information storage in the root canal motor to form an integrated design, as shown in Figure 2; the other is wireless motor handle and host control. The split design is composed of the device, and the two are interconnected through wireless signals, as shown in Figure 3.

As shown in Figure 2, in the information storage of the integrated root canal motor B-1, the working parameters of the root canal instrument A-1 for selection are preset, and the selection button B-2 and the working parameters of the instrument are set on the handle. Display window B-3. When using, first install the selected root canal instrument A-1 on the head of the root canal motor, and then according to the working conditions of the instrument, select the same root canal instrument A-1 by selecting the button B-2 and the display window B-3. Matching various working parameters, such as speed, maximum torque, working mode (continuous forward rotation, alternating forward and reverse rotation, reverse rotation after being blocked), etc. After the operator manually confirms that the parameters are correct, press the work key B-4, and the root canal instrument A-1 will move according to the selected parameters.

As shown in Figure 3, in the design that the wireless motor handle and the host controller are interconnected through wireless signals, the host controller C-1 is pre-installed with working drivers of different types and specifications of root canal instruments, which can be accessed through the display interface C of the host controller. -2 and button C-3, select the type and specification of the root canal file, after the selection is completed, press the signal transmission button C-4, the working driver of the instrument is transmitted to the wireless handle C-6 through the wireless signal C-5 . A power supply, a signal receiving device and an information storage device are installed in the wireless handle C-6, which can receive the signal sent by the host controller and store it. After the reception is completed, the receiving indicator C-7 on the wireless handle will light up. Press the work key C-8, the root canal instrument A-1 will move according to the work driver selected on the host controller C-1. This design has certain advantages over the integrated root canal motor. For example, the working parameters of various specifications and types of instruments are programmed to avoid the tedious process of setting each parameter one by one. At the same time, it can be performed on the large screen of the host controller. The selection improves the convenience and safety of system operation.

The above root canal motor system design, whether it is an integrated design or a split design composed of a wireless handle and a host controller, has a common problem, that is, the model and specification of the root canal instrument needs to be manually identified, and the corresponding device Operating parameters or programs require manual selection and confirmation by the operator. Such a design brings certain risks to the safe use of the device. This is because first, the specifications of the mechanical root canal instruments are identified by a single color ring, and the color ring logo can only indicate the diameter of the tip of the instrument, while for the taper, working speed, maximum torque and other information of the instrument, the operator is required. It can only be confirmed by comparing according to the instrument description documents, which brings inconvenience to the specific operation; secondly, the area of the color circle of the mechanical root canal instruments is very small, and in the case that the color difference between the colors is not obvious, it will bring certain advantages to the identification. Third, in an operation process, it is often necessary to use multiple instruments alternately, which requires multiple selection and confirmation of the parameters or procedures of instruments of different types and specifications, which can easily lead to wrong selection. , which poses a safety hazard to the operation.

In the disclosed designs of root canal instruments and root canal motor systems, after the specifications and models of the instruments to be used are determined, the selection of working parameters or procedures corresponding to the instruments needs to be done manually by the operator. For the instrument and the root canal motor, they are independent of each other, that is, the root canal motor cannot judge whether the installed instrument can accurately correspond to the selected working parameters or procedures, and it depends entirely on whether the operator has performed an accurate operation.

In fact, with the application of advanced materials (such as NiTi alloy) in the field of root canal instruments, the advancement of instrument processing and manufacturing technology, and the improvement of understanding of root canal therapy, a large number of new designs of root canal instruments have been emerging, such as Asymmetric section structure, space spiral structure, variable taper instruments, etc. At present, the method of using a single color ring to identify the specifications of the instrument has been unable to meet the expression of many information related to the safety of the use of the instrument. Therefore, a new technical solution is required to establish an information link between the instrument and the root canal motor to ensure that the instrument safety of use.
