Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to a medical gynecological pelvic cavity measuring tool and a protective cover. Background Art

[0002] The birth process of women can be divided into three stages: the first stage, the second stage and the third stage. The first stage is the cervical dilation period, which is the beginning of the labor process. It is divided into the latent stage and the active stage. It is mainly manifested by the dilation of the cervix and the descent of the head under the action of regular uterine contractions. The dilation of the cervix is ​​the result of regular uterine contractions after labor. The degree of dilation of the cervix can be determined through vaginal examination or anal examination; the degree of descent of the fetal head is an important observation indicator for determining whether the fetus can be successfully delivered vaginally. Through vaginal examination or anal examination, the position of the lowest point of the head skull can be clearly determined, and it can help determine the position of the fetus. In order to observe the labor process in detail, record the examination results in time, and deal with abnormalities as soon as possible, the partogram is currently used to record the cervical dilation curve and the head descent curve. These are two important indicators in the partogram, indicating the progress of the labor process and guiding the treatment of the labor process. Head descent curve: The relationship between the lowest point of the fetal skull and the ischial spine plane indicates the degree of descent of the fetal head. The ischial spine plane is a sign for judging the height of the fetal head. The fetal head does not descend significantly during the latent phase, but it descends faster during the active phase, with an average descent of 0.86 cm / h, which can be used as an effective indicator for estimating difficult labor. Currently, traditional vaginal digital examination is still the main method for evaluating this indicator, but relevant studies have shown that vaginal digital examination is highly subjective.

[0003] Pelvic organ prolapse is a syndrome that often involves multiple organs. The severity of prolapse is graded using a variety of imprecise grading systems that are poorly reproducible and make it difficult for clinicians to communicate on a consistent basis.

[0004] At present, the traditional grading of uterine prolapse and the traditional and half-distance grading of vaginal wall prolapse are no longer accepted by academic exchanges. Instead, the more universal POP-Q staging (Pelvic Organ Prolapse Quantification, POP-Q) of pelvic organ prolapse has replaced it. POP-Q staging was first proposed by Professor Bump et al. at AJOG in 1996. Although it was resisted in the first few years, with more and more research and literature support, it has become the preferred POP grading system of the International Continence Society (ICS), the American Urogynecological Society (AUGS) and the American Association of Gynecological Surgeons, and is also the only universal standard in the world.

[0005] The POP-Q staging system is an objective, site-specific system used to describe and stage female POP. By quantitatively measuring the points on the anterior, apex, and posterior walls of the vagina that represent the prolapsed vagina, a vaginal "topography" is drawn, and these anatomical points are then used to determine the stage of prolapse. The POP-Q staging vaginal map uses the hymen as a reference (point 0) and six points on the anterior, posterior, and apex of the vagina as indicator points (two points Aa and Ba on the anterior wall, two points Ap and Bp on the posterior wall, and two points C and D on the apex). The position changes of these six points relative to the hymen are used as a scale (indicator points located on the inner side of the hymen edge are recorded as negative numbers, and those located on the outer side of the hymen edge are recorded as positive numbers) to quantify prolapse. At the same time, the total vaginal length (tv l), the height of the genital hiatus (gh), and the length of the perineal body (pb) are recorded. Using some representative points and distances, the POP-Q staging system better evaluates the state of the pelvic floor defect anatomy exposed to the vaginal cavity. These landmarks indirectly reflect some functional indicators. It is more like a diagnostic standard and quantitative indicator, telling people the location and degree of prolapse.

[0006] At present, clinicians mainly use original rulers for measurement, or homemade modified tongue depressors for measurement, or even use the number of finger joints to estimate the distance of each measurement point; not only that, due to the narrow field of vision of the human body cavity, it is difficult for medical workers to correctly complete the scale reading work in the cavity in a short time, and the scale position may be forgotten after taking out the reading.

[0007] After searching, the Chinese invention patent with the application date of September 29, 2019 and the application number of 201910931540.4 discloses a pelvic organ prolapse measuring instrument. The patent only requires the operator to place the vertex scale of the scale body at the measurement starting point in the cavity, and move the cursor manually in the cavity, place the cursor at the measurement end point, and then take out the instrument to read the measurement results outside the body. That is, the patent is a manual tool that requires manual control of the cursor to move. After the cursor moves into place, the data cannot be read and recorded immediately, the measurement efficiency is low, and the measuring instrument needs to be disinfected every time it is used, which is very troublesome and not convenient to use.

[0008] Therefore, how to provide a medical obstetrics and gynecology pelvic measurement tool and a protective cover to improve the efficiency and accuracy of pelvic measurement has become an urgent problem to be solved. Summary of the invention

[0088] Working principle of the present invention:

[0089] Prolapse measurement:

[0090] The protective cover body 20 is sleeved on the measuring rod 9, and the buckle 30 is clamped on the clamping slot 12 to fix the protective cover body 20 on the housing 1; the power button 42 is pressed to start the measuring tool 100. The housing 1 is held by the handle end, and the protective cover body 20 is inserted into the cavity, and the front end of the protective cover body 20 abuts against the measuring starting point in the cavity.

[0091] When the forward key 43 is pressed, after the MCU2 receives the trigger signal of the forward key 43, it controls the transmission mechanism 8 to transmit through the drive circuit 7, thereby driving the measuring rod 9 to extend to the longest state and just abut against the protective cover body 20; when the backward key 44 is pressed, after the MCU2 receives the trigger signal of the backward key 44, it controls the transmission mechanism 8 to transmit through the drive circuit 7, thereby driving the measuring rod 9 to retract, and the cursor 10 to retract together. When the medical worker observes that the cursor 10 moves to the target position through the protective cover body 20, he stops pressing the backward key 44. The MCU2 calculates the movement distance of the cursor 10 through the transmission conversion ratio of the transmission mechanism 8, thereby obtaining the relative distance between the target anatomical position point of the human pelvis and the reference anatomical position point of the pelvis, and displays the measurement result on the touch screen 41; when the measurement is completed, the protective cover 200 is discarded.

[0092] Fetal head position measurement:

[0093] The protective cover body 20 is sleeved on the measuring rod 9, and the buckle 30 is clamped on the clamping slot 12 to fix the protective cover body 20 on the housing 1; the power button 42 is pressed to start the measuring tool 100. The handle end of the housing 1 is held, and the protective cover body 20 is inserted into the cavity, and the front end of the protective cover body 20 abuts against the fetal head.

[0094] Press the forward key 43 to extend the measuring rod 9 to its longest state and abut against the protective cover body 20; press the backward key 44 to retract the measuring rod 9 and the cursor 10; after the medical worker observes through the protective cover body 20 that the cursor 10 is aligned with the horizontal line of the ischial spine, he stops pressing the backward key 44, and the MCU2 calculates the movement distance of the cursor 10 through the transmission conversion ratio of the transmission mechanism 8, obtains the distance from the fetal head to the ischial spine, and displays it on the touch screen 41; through multiple measurement records, the average descent distance of the fetal head per hour can be obtained as an indicator for estimating the difficulty of delivery.

[0095] In summary, the advantages of the present invention are:

[0096] 1. By setting the MCU, the human-computer dialogue module, the drive circuit, the transmission mechanism, the measuring rod, the cursor, the wireless communication module and the printer, the human-computer dialogue module sends a control instruction to the MCU, so that the MCU controls the transmission mechanism to transmit through the drive circuit, and then drives the measuring rod to extend and retract. When the cursor is observed to move to the target position, the movement of the measuring rod is suspended through the human-computer dialogue module. The MCU calculates the movement distance of the cursor through the transmission conversion ratio of the transmission mechanism, thereby obtaining the relative distance between the target anatomical position point of the human pelvis and the reference anatomical position point of the pelvis, and displays the measurement result on the human-computer dialogue module. The measurement result is printed through the printer as needed, or the measurement result is directly transmitted to the host computer through the wireless communication module. Compared with the traditional method of manually controlling the cursor to move and using the original scale measurement, the measurement result needs to be manually recorded after the measurement is completed, which greatly improves the efficiency of pelvic measurement; compared with the traditional method of estimating the distance of each measurement point using the number of finger joints, the accuracy of pelvic measurement is greatly improved.

[0097] 2. By setting the protective cover body and the buckle, the protective cover body is put on the measuring rod and fixed to the slot by the buckle, so that the measuring rod can be extended and retracted in the protective cover body; the protective cover body is made of transparent material, which is convenient for observing the moving position of the cursor; when a measurement is completed, the protective cover can be discarded, and when a new patient needs to be measured, a new protective cover can be put on. Compared with the need to disinfect each time the measuring tool is used directly, the efficiency of pelvic measurement is improved while ensuring safety, and the convenience of using the measuring tool is improved.
