Description

Cervical probe

Technical Field

The utility model relates to the technical field of medical equipment, more specifically say, it relates to a cervical probe.

Background

Prior to cervical surgery, a physician typically performs an ultrasound examination (typically a transvaginal ultrasound examination) to measure cervical tube length. The cervical tube length measurement helps to assist the operating doctor to make a detailed and specific operation scheme so as to ensure the operation process and the operation safety of the patient to the maximum extent, and to keep the cervical tube with the proper length and the enough length as much as possible after the operation. However, during the operation, the operator still needs to measure the length of the cervical canal by himself or herself again, and know the direction of the cervical canal.

Currently, there is no cervical canal probe specially used for measuring the length and direction of the cervical canal in the market, and the operator can only replace the uterine probe, but since the depth of the uterine cavity of a female in the childbearing age group is generally 7 to 8 cm, the scale of the uterine probe starts from 5cm, and has no scale before 5 cm. The length of the cervical canal of women in the childbearing age is generally 2.5cm to 3cm, so the uterine probe cannot accurately estimate the length of the cervical canal.

SUMMERY OF THE UTILITY MODEL
