19 results about "Cervical canal" patented technology

The cervical canal is the spindle-shaped, flattened canal of the cervix, the neck of the uterus. It communicates with the uterine cavity via the internal orifice of the uterus (or internal os) and with the vagina via the external orifice of the uterus (ostium of uterus or external os). The internal orifice of the uterus is an interior narrowing of the uterine cavity. It corresponds to a slight constriction known as the isthmus that can be seen on the surface of the uterus about midway between the apex and base. The external orifice of the uterus is a small, depressed, somewhat circular opening on the rounded extremity of the cervix, opening to the vagina. Through this aperture, the cervical cavity communicates with that of the vagina.

Methods for postpartum uterine hemostasis

ActiveUS12616503B2Balloon catheterMedical devicesPostpartum haemorrhageCol uterin
A method of uterine hemostasis involves inserting a suction line of a postpartum hemorrhage mitigation device through a cesarian incision into the uterine cavity, guiding the suction line through the cervix and into the vagina, positioning an anchoring mechanism of the device adjacent the internal cervical OS of the uterine cavity, closing the cesarian incision to enclose the suction line within the uterine cavity, and connecting the suction line to a negative pressure source that introduces negative pressure to the uterine cavity via the suction line, thereby causing contraction of the uterus and evacuation of fluid from the uterus via the suction line extension. Upon completion of a treatment period, the negative pressure source is disconnected, and the suction line and anchoring mechanism are extracted from the uterus through the cervical canal and the vagina.

Adenomyosis diagnosis method and system based on cervical multi-parameter ultrasound imaging

PendingCN122272075AParenchymaBlood flow
This invention relates to the field of ultrasound imaging diagnostic technology, and discloses a method and system for diagnosing adenomyosis based on multi-parameter ultrasound imaging of the cervix. The method utilizes a transvaginal probe to acquire two-dimensional grayscale, shear wave elasticity, and ultra-micro blood flow images of the cervix. An anatomical coordinate system is established based on the longitudinal axis of the cervical canal in the grayscale image, and multiple independent quantitative analysis sub-regions covering the internal os and mid-segment of the cervix are identified as measurement target areas within the cervical parenchyma. Young's modulus, reflecting tissue stiffness, and resistance index, reflecting microcirculatory resistance, are extracted from the elasticity and blood flow images, respectively. The extracted parameters are input into a multivariate logistic regression diagnostic model, and the probability value of disease risk is calculated based on weighted coefficients, outputting a classification conclusion. This invention overcomes the limitations of morphological diagnosis through a standardized target area localization strategy and multi-modal parameter joint modeling, achieving objective quantitative diagnosis of adenomyosis and improving the accuracy and repeatability of detection.
