The utility model relates to medical instrument technical field discloses a kind of noninvasive cervical cerclage buckles, including flexible kit, one end of flexible kit is provided with upper connecting ring, the other end is provided with lower connecting ring, upper connecting ring inside is provided with the upper annular passage for accommodating first connecting buckle, one end of first connecting buckle enters from the side import of upper annular passage, and it is passed out from the other side export of upper annular passage by the inside of upper annular passage.The utility model is fixed on cervix by setting upper connecting ring and lower connecting ring on the upper and lower ends of flexible kit, and setting the first, second connecting buckle that can be tightened on upper and lower connecting ring, reach the purpose of bundling.Compared with cervical cerclage, it has the superiority of noninvasive, fast, without anesthesia, compared with the cervical support product on market, can provide high-quality individualized product for patient, release the compression to vaginal wall and pelvic tissue, effectively avoid the irritation and harm of operation to cervical tissue.

This invention relates to the field of photoelectric probes, specifically a multi-point photoelectric probe for cervical cancer screening instruments. It includes a probe body and a detector handle. The probe body adopts a slender, hollow tubular structure, serving as the support and wiring main body for the probe, and internally housing multiple independent optical fibers. An end-face detection section, located at the very front of the probe, is elliptical in shape and is a dedicated cervical tissue detection component. A ring-shaped detection section, fitted onto the ring-shaped side of the probe body behind the end-face detection section, is a dedicated vaginal wall tissue detection component. An adjustment section is used to adjust the orientation of the end-face detection section, expanding the detection range and ensuring that all areas of the cervix can be effectively detected. The front end of the probe body is fixedly connected to the end-face detection head, and the rear end is detachably connected to the detector handle. This multi-point photoelectric probe for cervical cancer screening instruments, through its separate dedicated design of the end-face and ring-shaped detection heads, achieves for the first time simultaneous screening of both the cervix and vaginal wall areas with a single probe insertion.

The utility model discloses a kind of for cervical conization specimen's split piece device, it is related to pathological analysis technical field, including base, the position of the outside of base near upper side is threadedly connected with threaded sleeve, the upper side of threaded sleeve is rotatably connected with cutting mechanism, the outside of cutting mechanism is movably sleeved with fixed mechanism, the upper side middle part of base is movably installed with electric push rod, the cutting mechanism includes mechanism pipe, the upper side of mechanism pipe is fixedly connected with conical seat, the lower side of mechanism pipe is rotatably connected in the upper side of threaded sleeve, the upper side of electric push rod is fixedly connected with fixed rod.The utility model said a kind of for cervical conization specimen's split piece device, directly drive blade to go up by electric push rod, so that blade carries out cutting to cervical tissue, electric push makes it unnecessary to manually provide greater pressure to push blade, while electric push rod can hide blade in mechanism pipe, more safe.

The application discloses a kind of long-term treatment strategy making methods for cervical cancer prevention and treatment of HPV, belong to medical information processing technical field.The method includes: obtaining the digital HPV health record containing multiple HPV typing detection results, cervical cytology history record and individual physiological characteristic parameters;Three-dimensional treatment situation cube is constructed by virus infection state subspace, cervical tissue state subspace and treatment intervention state subspace;In the cube, state backtracking and forward-looking deduction algorithm based on time axis are used, virus clearance probability field and lesion outcome probability field are calculated;High-risk persistent infection space-time region and low-risk self-healing tendency space-time region are demarcated;Current patient state is projected to the cube, if fall into high-risk region, then trigger long-term treatment strategy generation process including multiple treatment stages, output intervention opportunity, intensity and state transition condition of each stage.

A system for providing information for diagnosing preterm birth risk includes: two or more transmit electrodes, contacting cervical tissues, for applying a plurality of first signals at different frequencies to the cervical tissues, two or more detect electrodes, contacting the cervical tissues, for detecting a plurality of second signals generated in response to the first signals, the second signals corresponding to the first signals, and a source configured to generate a plurality of signals. The system obtains a plurality of impedances of the cervical tissues based on the first and the second signals and applies data quality requirements for diagnosing the preterm birth risk. The data quality requirements include checking at least one of signal generation, signal reception, impedance calculation, quality of the first signals, quality of the second signals, and the impedances. The system includes a diagnosis engine configured to receive data including impedances that satisfy the data quality requirements, classify the data into different groups, each representing different status, based on correlation between the data, patient's information and the preterm birth risk, and output information for diagnosing the preterm birth risk.
