Description

Calliper type measuring appliance for obstetrics

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a caliper type measuring device for the obstetrics and gynecology department.

Background

The process of female childbirth can be divided into three stages: first, second and third labor. The first stage of labor is the cervical dilatation phase, which is the beginning of labor and is divided into the latent phase and the active phase, which are mainly characterized in that under the action of regular uterine contraction, the uterine orifice is dilated and the fetal head is descended. The expansion of the uterine orifice is the result of regular uterine contraction after parturition, and the expansion degree of the uterine orifice can be determined through vaginal examination or anal examination; the descending degree of the fetal head is an important observation index for determining whether the fetus can be delivered smoothly through the vagina, and the position of the lowest point of the fetal head and the skull can be determined through vaginal examination or anal examination, and the fetal orientation can be judged in an assisted manner. In order to observe the labor process in detail, record the examination result in time and process the abnormal condition as early as possible, most of the prior art adopts a labor process chart (partogram), traces a uterine opening expansion curve and a fetal head descending curve, which are two important indexes in the labor process chart, indicate the progress of the labor process and guide the labor process. Fetal head descent curve: the descending degree of the fetal head is indicated by the relation between the lowest point of the fetal head and the skull and the plane of the ischial spine. The ischial spine plane is a mark for judging the height of the fetal head. The fetal head in the latent period does not drop remarkably, the decline in the active period is accelerated, and the average decline is 0.86cm/h, so that the method can be used as an effective index for estimating the delivery difficulty. At present, the traditional vaginal digital examination is still the main method for evaluating the index, but related studies prove that the vaginal digital examination has greater subjectivity.

During pregnancy, as a fetus grows in the uterus, the uterus is continuously enlarged, the enlarged uterus can expand and extend the abdominal wall, the rectus abdominis on two sides can be separated from the position of the abdominal midline, namely the leucorrhea, to two sides, the phenomenon is called abdominal rectus separation, the abdominal wall can be gradually recovered from the last half year to one year under normal conditions, if the abdominal rectus abdominis is not recovered for a long time and the distance exceeds 2cm, treatment is recommended, and if correct treatment is not obtained, body deformation, long-term aching pain of the waist and the back can be caused, the stability of the pelvis is reduced, hernia and organ displacement can be caused seriously. Currently, most of clinical examinations are performed by adopting an abdominal palpation method, namely, the fingers of an examination physician are pressed down lightly to check whether the rectus abdominis separated or not, and the separation distance of the rectus abdominis is estimated according to the number of the insertable fingers, so that the precision is poor.

Pelvic organ prolapse is a syndrome involving multiple organs. In diagnosis and nomenclature, grading of prolapse severity employs a number of imprecise grading systems that are poorly reproducible and result in difficult communication between clinicians through uniform criteria.

At present, the traditional graduation of uterine Prolapse and the traditional and half-range graduation of vaginal wall bulging are not accepted by academic communications, and are replaced by the more general POP-Q stage of Pelvic Organ Prolapse (POP-Q). POP-Q staging was first proposed by professor bum, et al, on AJOG in 1996 and, although more resistance was experienced in the first few years, it has now become the preferred POP staging system for the International urinary control society (ICS), the American urology society (AUGS), and the American society of gynecologic surgeons, with increasing research and literature support, and is currently the only standard in common use internationally.

POP-Q staging is an objective, site-specific system for the description and staging of female POPs. The stage of prolapse is determined by quantitatively measuring various points representing the anterior, apical, and posterior walls of the prolapsed vagina to map the vaginal "topography". POP-Q staged vaginal picture is referenced to hymen (point 0) and indicated at 6 points of the anterior, posterior and top walls of the vagina (two points Aa, Ba on the anterior wall, two points Ap, Bp on the posterior wall, two points C, D on the top). The 6 points vary in scale relative to the position of the hymen (the indicator points are negative numbers on the inside of the hymen limbus and positive numbers on the outside of the hymen limbus) and quantification of prolapse is made. The total vaginal length (tvl), height of the genital tract fissure (gh), length of the Perineal body (pb) were also recorded. By using a plurality of representative points and distances, the POP-Q stage better evaluates the state of exposure to the vaginal cavity surface in pelvic floor defect anatomy, and the mark points indirectly reflect a plurality of functionally related indexes. It is more like a diagnostic standard and quantitative index, telling people the position and degree of prolapse.

At present, clinicians mainly use an original graduated scale for measurement, or self-made and reconstructed tongue depressors for measurement, and even use the number of finger knuckles to estimate the distance of each measurement point; moreover, due to the narrow visual field of the human body cavity, the medical worker is difficult to accurately complete the scale reading work in the cavity in a short time, and the reading can be forgotten to be calibrated.

Therefore, how to provide a caliper-type measuring device for obstetrics and gynecology department to improve the efficiency and accuracy of measurement becomes a problem to be solved urgently.
