Description

Technical Field

[0001] The present invention relates to the technical field of B-ultrasound imaging, and in particular to a method for reducing differences in hand feeling among B-ultrasound imaging operators. Background Art

[0002] During the B-ultrasound imaging of the patient's abdomen, the operating physician will press the B-ultrasound probe alternately lightly and heavily to contact the patient's abdominal skin, and the patient's abdominal muscles will produce stress contraction and relaxation. After the abdominal muscles contract, it is conducive to the transmission of ultrasound, making the ultrasound imaging clearer. However, the pressing force will change with the fatigue of the physician's wrist, causing the degree of stress contraction of the abdominal muscles to change. In addition, there are differences in the degree of stress contraction among individual patients, causing the B-ultrasound image to be affected by the difference in the operator's hand feel, resulting in misdiagnosis or difficulty in diagnosis, and then requiring further examination with sophisticated and expensive medical technologies such as CT or MRI. This is extremely unfriendly to patients with financial constraints or in remote areas. Therefore, it is necessary to invent a method to reduce the detection difference caused by the difference in the operator's hand feel. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention attempts to overcome the above defects. Therefore, the present invention provides a method for reducing the differences in the hand feel of B-ultrasound imaging operators, thereby solving the measurement differences caused by the differences in the hand feel of operators during the B-ultrasound imaging process.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for reducing the differences in hand feel among B-ultrasound imaging operators, wherein a B-ultrasound probe is additionally provided with a vibration accessory at a position close to the patient's skin, and the vibration accessory consists of a plastic annular sleeve and a linear vibration motor. The plastic annular sleeve is embedded with the linear vibration motor, and the plastic annular sleeve surrounds the end of the B-ultrasound head. The B-ultrasound probe is also provided with a switch that is convenient for finger pressing. The linear vibration motor is electrically connected to a driving power supply through the switch, and the switch controls the start and stop of the linear vibration motor.

[0005] Furthermore, the plastic annular sleeve is made of TPE, TPU or silicone.

[0006] Furthermore, the vibration direction of the linear vibration motor is perpendicular to the patient's skin surface.

[0007] Furthermore, the vibration frequency of the linear vibration motor is 50-200 Hz.

[0008] Furthermore, the total power of the linear vibration motor is 5-15 watts.

[0009] Furthermore, the switch is adhered to the surface of the B-ultrasound probe by double-sided tape.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The stress contraction of the patient's subcutaneous muscles is changed from being generated by the original artificial wrist pressure to being generated by a linear motor, which is free from the constraints of the operating physician's touch and does not rely on the operating physician's touch, ensuring the consistency of the physician's technique and reducing the operating physician's fatigue. At the same time, the vibration of the linear vibration motor itself can also make the boundary layer of the muscle layer and the internal organs more closely combined, further weakening the echo signal of the boundary layer, which is beneficial to improving the accuracy of B-ultrasound imaging. The plastic annular sleeve of the present invention is easy to install, and the switch can be attached to the surface of the B-ultrasound probe by double-sided tape, which is convenient and fast. The driving wire of the linear vibration motor can be bundled with the cable of the B-ultrasound probe and set in parallel without changing the original circuit of the B-ultrasound equipment. It is easy to perform simple modification on the original B-ultrasound equipment, has good scalability, low cost, and good promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0014] The present invention provides a method for reducing the difference in hand feeling of B-ultrasound imaging operators, such as Figure 1As shown, the B-ultrasound probe 1 is additionally provided with a vibration accessory at a position close to the patient's skin 4. The vibration accessory consists of a plastic annular sleeve 2 and a linear vibration motor 3. The plastic annular sleeve 2 is embedded with the linear vibration motor 3. The plastic annular sleeve 2 surrounds the end of the B-ultrasound head. The B-ultrasound probe 1 is also provided with a switch that is convenient for finger pressing. The linear vibration motor 3 is electrically connected to the driving power supply through the switch. The switch controls the start and stop of the linear vibration motor 3. The material of the plastic annular sleeve 2 is TPE, TPU or silicone. The vibration direction of the linear vibration motor 3 is perpendicular to the surface of the patient's skin 4. The vibration frequency of the linear vibration motor 3 is 50-200Hz. Multiple linear vibration motors 3 are provided. The total power of the linear vibration motor 3 is 5-15 watts. The switch is attached to the surface of the B-ultrasound probe 1 by double-sided tape.

[0015] Working principle: During B-ultrasound imaging, the operator presses the switch to turn on the linear vibration motor 3. The patient's skin feels the vibration, and the subcutaneous muscles produce stress contraction. The muscle contraction causes the elastic modulus of the muscle to increase. At the same time, the muscle contraction causes the contact between the muscle layer and the internal organs to become closer. The increase in the elastic modulus of the muscle weakens the attenuation of the ultrasound, which is beneficial to the penetration of the ultrasound and increases the intensity of the ultrasound echo. The closer contact between the muscle layer and the internal organs can weaken the echo signal of the boundary layer, which is beneficial to distinguishing the boundary layer echo from the internal organ echo and improving the accuracy of B-ultrasound imaging. At the same time, the vibration of the linear vibration motor 3 itself can also make the boundary layer more tightly combined, further weakening the echo signal of the boundary layer.

[0016] Example of a B-ultrasound probe with a square cross section Take a section of TPE hose and prepare 10 linear vibration motors 3 with a single power of 1.5 watts, 5 in a group, fix the edges of the 5 linear vibration motors 3 with glue to make two groups of linear vibration motor groups, and electrically connect the 10 linear vibration motors in parallel. Set two drive lines, and insert the two groups of linear vibration motor groups from the two openings of the TPE hose respectively. Then glue the two openings together to form a plastic annular sleeve 2. At the same time, lead out two drive lines, and insert the plastic annular sleeve 2 into the end of the B-ultrasound probe 1. The positions where the linear vibration motor groups are embedded in the plastic annular sleeve 2 are respectively located at the positions of the two long sides of the cross section of the B-ultrasound probe 1, as shown in FIG. Figure 2 After the two driving wires are led out, they are electrically connected to the driving power supply through a switch, and the switch is attached to the surface of the B-ultrasound probe 1 through double-sided tape.

[0017] An embodiment of a circular cross-section of a B-ultrasound probe Take a section of TPE tubing and prepare eight linear vibration motors 3, each with a power of 1.5 watts. The eight linear vibration motors are electrically connected in parallel, and two drive lines are set. The eight linear vibration motors are evenly spaced and inserted into the TPE tubing. The two openings are then glued together to form a plastic annular sleeve 2. Two drive lines are then led out, and the plastic annular sleeve 2 is inserted into the end of the B-ultrasound probe 1. The eight linear vibration motors are evenly spaced around the B-ultrasound probe 1, as shown in the following figure. Figure 3 After the two driving wires are led out, they are electrically connected to the driving power supply through a switch, and the switch is attached to the surface of the B-ultrasound probe 1 through double-sided tape.

[0018] The TPE hose, glue, linear vibration motor, switch and the driving power module (circuit board) of the linear vibration motor can be easily purchased online at a low price, which provides a basis for the easy promotion of the present invention.
