Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, in particular to a device for measuring rectus abdominis separation. Background Art

[0002] Rectus abdominis separation, abbreviated as DRA, is an abnormal symptom of the anterior abdominal wall. It refers to the separation of the belly of the rectus abdominis at the linea alba, that is, the distance between the inner edges of the rectus abdominis on both sides is abnormally widened. When the distance widens by more than 20mm, it is DRA, which is most common in women in late pregnancy and early postpartum. The rectus abdominis plays an important role in posture, breathing, defecation, delivery, abdominal organ support, trunk and pelvic stability, etc. DRA not only affects the appearance, but also causes abdominal dysfunction when the separation is severe, which can cause abdominal pain, discomfort, lumbar pelvic pain or urogynecological symptoms, including pelvic organ prolapse, urinary incontinence and fecal incontinence, etc., and may gradually worsen with exercise, weaken the abdominal muscle strength, and damage to the linea alba can progress to abdominal wall hernia. Some scholars even believe that long-term DRA may reduce the ability of women of childbearing age to give birth to the next generation.

[0003] At present, the diagnostic methods of DRA include clinical examination and imaging examination. The commonly used clinical examination methods are finger palpation and caliper measurement. In the finger palpation method, the examiner puts his fingers together and presses down, and uses the width of his fingers to measure the distance between the inner edges of the rectus abdominis on both sides. However, the examiner's finger widths are different during palpation, and the subjective feeling of abdominal soft tissue pressure is different. It is difficult to detect DRA objectively and accurately, and the repeatability and comparability of patient follow-up are also poor. The caliper measurement method is similar to the former. It uses tools to measure the inner edges of the rectus abdominis on both sides. Compared with the former, the error is smaller and the measurement result is more accurate, but it is subcutaneous. For patients with thicker fat and obviously loose abdomen, the accuracy of caliper measurement based on surface positioning is significantly reduced, and it is difficult to identify the edges of the rectus abdominis on both sides during pregnancy, and it is impossible to accurately and objectively monitor the changes in the rectus abdominis separation during the perinatal period. Imaging examinations include ultrasound, CT and MRI. Among them, ultrasound examinations are in great demand and have long waiting times, which results in most mothers being unable to complete the rectus abdominis examination on the same day, greatly affecting their daily lives. CT examinations are expensive and are not suitable for pregnant women due to radiation. MRI examinations are expensive and take a long time, making them unsuitable for monitoring pregnant women.

[0004] Therefore, those skilled in the art have proposed a device for measuring rectus abdominis separation to solve the problems raised by the background art. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a device for measuring rectus abdominis separation, so as to solve the problem that the commonly used clinical examinations and imaging examinations in the prior art each have shortcomings and cannot be used as conventional examination methods for DRA.

[0006] A rectus abdominis separation measuring device comprises surgical forceps, wherein the forceps mouth is provided with a linear displacement sensor, one end of the surgical forceps is provided with a display component, and the other end of the surgical forceps is provided with a scale.

[0023] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] Embodiment 1

[0025] As attached Figure 1 To Attachment Figure 2 As shown, the present invention provides a rectus abdominis separation measuring device, comprising a surgical forceps 1, wherein the surgical forceps 1 is an operating body, the jaws of the surgical forceps 1 are provided with a linear displacement sensor 3, and the length of the rectus abdominis separation is measured by the linear displacement sensor 3, one end of the surgical forceps 1 is provided with a display component 4, and the data measured by the linear displacement sensor 3 is displayed by the display component 4, and the other end of the surgical forceps 1 is provided with a scale 5, wherein the scale 5 is a telescopic ruler, which can provide a larger measurement range, and the depth of the rectus abdominis separation is measured by the scale 5.

[0026] As can be seen from the above, when the patient does sit-ups, a depression is formed in the patient's abdomen due to the separation of the rectus abdominis. The jaws of the surgical forceps 1 are inserted into the depression, and the doctor controls the degree of opening and closing of the surgical forceps 1 until the jaws of the surgical forceps 1 contact the rectus abdominis. The length of the separation of the rectus abdominis is measured by the linear displacement sensor 3, and the display component 4 displays the data measured by the linear displacement sensor 3, which is convenient for the doctor to view the data. The depth of the depression can also be measured by the ruler 5.

[0027] Embodiment 2

[0028] As attached Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that the display component 4 includes a shell, in which a signal amplifier, an analog-to-digital converter, a microcontroller and a display screen are arranged, the linear displacement sensor 3 is electrically connected to the signal amplifier, the signal amplifier is electrically connected to the analog-to-digital converter, the analog-to-digital converter is electrically connected to the microcontroller, the microcontroller is electrically connected to the display screen, and an observation window is opened on the shell, through which the information on the display screen can be seen.

[0029] As can be seen from the above, the linear displacement sensor 3 converts the measured information into an electrical signal, the electrical signal is amplified by the signal amplifier and transmitted to the analog-to-digital converter, the analog-to-digital converter converts the amplified electrical signal into a digital signal, the microcontroller processes the digital signal, and controls the display screen to display the measured data.

[0030] Embodiment 3

[0031] As attached Figure 2 As shown, this embodiment is basically the same as the previous embodiment, except that the jaws of the surgical forceps 1 are provided with an enlarged portion 6, the shape of the enlarged portion 6 is relatively rounded, which can reduce irritation to the patient's skin, and the linear displacement sensor 3 is located in the enlarged portion 6.

[0032] As attached Figure 3 To Attachment Figure 4 As shown, specifically, the other end of the surgical forceps 1 is fixedly connected to a rotating disk 7, and the rotating disk 7 is rotatably connected to a rotating column 8. The scale 5 can be rotated on the rotating disk 7 through the rotating column 8, so as to adjust the angle of the scale 5. The rotating column 8 is slidably connected to the scale 5, and the scale 5 can slide along the rotating column 8, so as to adjust the height of the scale 5.

[0033] As attached Figure 4 As shown, further, the rotating column 8 is composed of a plug post and a slider, the rotating disk 7 is provided with a groove 9, the plug post is located in the groove 9, the scale 5 is provided with a slide groove 10, and the slider is located in the slide groove 10.

[0034] As attached Figure 2 As shown, further, the handle of the surgical forceps 1 is connected to a hanging ring 11, and the hanging ring 11 is connected to a torsion spring 12. When the surgical forceps 1 are in a closed state, the torsion spring 12 is squeezed and deformed, and the torsion spring 12 returns to its original state to assist the handle and the jaws of the surgical forceps 1 to open, thereby assisting the doctor in his work.

[0035] As can be seen from the above, the doctor rotates the ruler 5 downward to the jaws of the surgical forceps 1 and slides the ruler 5 downward. At this time, the ruler 5 slides along the slider through the slide groove 10, which is convenient for measuring the depth of the depression. The ruler 5 can also be extended to provide a larger measurement range; the doctor rotates the ruler 5 upward to the handle of the surgical forceps 1. At this time, the ruler 5 drives the rotating column 8 to rotate on the rotating disk 7 and slides the ruler 5 upward to prevent the ruler 5 from affecting the linear displacement sensor 3.
