Description

An instrument for palpation of pain in the oral and maxillofacial system

technical field

The invention relates to palpation, in particular to an accurate palpation instrument for assisting pain in the oral and maxillofacial system, and belongs to the technical field of medical equipment auxiliary equipment.

Background technique

Pain is a complex physiological and psychological activity, and it is also the most common clinical symptom. In 2001, the World Health Organization listed pain as the fifth vital sign following body temperature, respiration, pulse, and blood pressure. Pain of various natures originating from the face, neck and oral cavity is called orofacial pain. Common odontogenic pain, temporomandibular joint and masticatory muscle pain. Among them, "pain in the joint area and corresponding muscle groups" has become the most common reason for patients with temporomandibular joint disease to see a doctor, and it is also the first complaint of patients with temporomandibular joint disease, the fourth largest disease of the oral cavity.

At present, the clinical examination for the above-mentioned areas mostly adopts palpation examination, which is highly subjective. During the examination, the doctor uses the palm of the fingertip, index finger or middle finger to palpate the orofacial pain area and apply a certain amount of pressure to fully stimulate the orofacial muscles and the temporomandibular joint area to determine whether they are the cause of the pain. Among them, the strength of palpation is the difficulty and focus of this examination. Too small palpation force cannot cause pain symptoms, while too much force will cause unnecessary tenderness and pain after examination. As a reference, there have been TMD research diagnostic standards recommending that a force of about 900g be used when palpating the muscles outside the mouth; and a force of about 450g should be used when checking the temporomandibular joint and intraoral muscles. However, the power of these precise data cannot be quantitatively used conveniently and quickly in the manual inspection of daily outpatient clinics. In addition, there may be differences in the palpation strength of the same examiner before and after two times, and the difference in palpation strength between different examiners is even greater, which is not conducive to the judgment of disease progression.

Contents of the invention

The purpose of the present invention is to provide a pain palpation instrument for the oral and maxillofacial system. The present invention focuses on solving the problem that the subjective judgment of palpation force is quite different, and designs a new type of oral and maxillofacial muscle palpation instrument, which can accurately provide oral and maxillofacial muscle palpation.

In the figure: a sensor 1, a processor 2, a display 3, a sounder 4, a spring 5, a touch rod 6, a shift lever 7, a housing 8, a first connecting piece 9, and a second connecting piece 10.

Detailed ways

As shown in FIGS. 1 and 2 , an oral and maxillofacial system pain palpation instrument includes a housing 8 , a touch rod 6 on the housing 8 , a sensor 1 , a processor 2 , a display 3 , and a sounder 4 .

The sensor 1 and the processor 2 are arranged in the housing 8, the sensor 1 is connected to the processor 2, the processor 2 is respectively connected to the sounder 4, the display 3, and the lever 7, and the end of the lever 7 protrudes from the shell Outside the body 8; the sensor 1 is arranged between the opposite first connecting piece 9 and the second connecting piece 10, and a spring 5 is also arranged between the first connecting piece 9 and the second connecting piece 10, and the first connecting piece 9 is connected with one end of the feeler rod 6, and the other end of the feeler rod 6 protrudes out of the housing 8. On the one hand, the spring provides elastic force to generate a corresponding external force when the contact rod is compressed; on the other hand, it provides a reset force to restore the contact rod to its original state.

The pressure acting on the touch rod 6 is transmitted to the sensor 1. When the pressure reaches the set value, the processor 2 transmits an electrical signal to the sounder 4, and the sounder 4 makes a sound, and the display 3 displays the real-time palpation force value.

Sensor 1 is a displacement sensor or a pressure sensor.

When a pressure sensor is used, the pressure acting on the contact rod 6 is transmitted to the sensor 1, and the sensor 1 converts the force signal into an electrical signal and transmits it to the processor 2. When the processor 2 determines that the strength of the electrical signal reaches the set value, that is, the pressure reaches the set value. When the value is fixed (500g or 1000g), the processor 2 sends an instruction to the sounder 4, and the sounder 4 makes a sound, and the display 3 displays the real-time palpation force value and blinks, as shown in FIG. 3 .

When the displacement sensor is used, the external pressure reaches the set value (500g or 1000g), and the compression amount of the internal spring can be calibrated in advance. The compression amount can be obtained by the displacement sensor and passed to the processor 2 for judgment. The specific process is: function The pressure on the contact rod 6 reaches the set value, and the pressure set value corresponds to the compression amount of the spring 5 inside the casing. The compression amount signal of the spring 5 is obtained by the displacement sensor 1 and converted into an electrical signal, which is transmitted to the processor 2 for judgment When the processor 2 determines that the electrical signal strength reaches the set value, the processor 2 transmits an instruction to the sounder 4, and the sounder 4 makes a sound, and the display 3 displays the real-time palpation force value and blinks. The displacement sensor can only measure the amount of compression and submit it to the processor for judgment. The amount of compression produced by 500g and 1000g pressure can be calibrated in advance and stored in the processor. The processor runs the program to judge whether the compression amount generated by the external pressure reaches the set value, as shown in Figure 3.

Sounder 4 is a buzzer.

The shifting lever 7 can change gear positions, including 3 gear positions, which are respectively closed, 500g, and 1000g.

The first connecting piece 9 and the second connecting piece 10 are ordinary steel plates, it is sufficient to ensure their rigidity.

A calibration system should be designed for sensor 1 and processor 2. There is a calibration device corresponding to the pressure of 500g and 1000g. The spring and the limit block are used to achieve the purpose of generating the pressure of 500g and 1000g. It is used for regular calibration of the palpation instrument, see Figure 4 and Figure 5.

The sensor 1, the processor 2, and the display 3 are all connected by circuits.

When it is necessary to palpate the temporomandibular joint area or muscle area, hold the instrument, and the touch rod 6 is close to the patient's muscle or joint area skin, and the finger pushes the palpation instrument to apply pressure to the muscle or joint area on the inspection side, and the pressure passes through the palpation. The rod is transmitted to the displacement sensor or pressure sensor, and the spring compression or pressure reaches the set value. The preset value is divided into two levels of 500g and 1000g, which can be adjusted through the lever 7. The buzzer sounds, and at the same time, the real-time palpation force value of 500g and 1000g is displayed on the digital display. With this instrument, doctors can accurately palpate muscles and joints with a specific palpation force, and judge whether there is tenderness in the palpation area, so as to assist the clinical examination and treatment of orofacial pain-related diseases.
