Obstetric clinical clamping and expanding device

Abstract

The invention discloses an obstetric clinical clamping and expanding device, which comprises an outer frame. A threaded rod is arranged on one side of the interior of the outer frame; the two ends ofthe threaded rod are rotationally connected with the two ends of the outer frame correspondingly; threads are formed in the outer part of the threaded rod; threads at two ends of the threaded rod areopposite in direction of turning; a guide rod is arranged on the side, away from the threaded rod, of the interior of the outer frame; the two ends of the guide rod are fixedly connected with the twoends of the outer frame correspondingly; two expanding frames are arranged in the outer frame; and moving blocks are fixedly connected to the two ends of the two expanding frames. A sliding chute is formed in the expanding sheet; and under the clamping of the clamping block, the expanding sheet stably slides relative to the expanding frame, so that the depth of the expanding sheet entering the lower body of a patient can be adjusted according to the actual condition of the patient, the injury to the patient due to over-deep insertion is avoided, the convenience in use of the device is improved, and the adaptability in assembly and use is enhanced.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an obstetric clinical clamping and expanding device. Background technique

[0002] During obstetrical clinical examination and treatment, it is often necessary to check the lower body. For some cases where the lower body is tight, it is necessary to use a stretching device to expand the lower body to expose the cervix and then observe the vaginal wall and vaginal fornix. Whether there are tumors, Abrasions, redness, growths, etc., as well as other physiological abnormalities;

[0003] There are following deficiencies in the prior art: at present, drag hooks and expansion forceps are generally used to operate, but there are many problems. For example, in actual use, the patient's legs cannot be supported, resulting in insufficient stability of the device during use, and The impact of the patient's legs cannot be avoided, and the insertion depth of the device cannot be eff...
