Disposable noninvasive cloth bag type obstetric forceps and knot pusher thereof

Abstract

The invention discloses disposable noninvasive cloth bag type obstetric forceps. The disposable noninvasive cloth bag type obstetric forceps comprise a cloth bag, supporting tubes, a pull strap and a tightening line, wherein the cloth bag is cylindrical; a tightening ring is arranged at the front end of the cloth bag; the supporting tubes are hollow, are parallel to the peripheral direction of a central shaft of the cloth bag and are uniformly arranged on a wall of the cloth bag; the pull strap penetrates in one ends of the supporting tubes and are fixed on the tensioning ring; the other end of the pull strap is freely arranged at the tail end of the cloth bag; an operating hole is formed in a portion, which is close to the tail end of the cloth bag, of each supporting tube; two ends of the tensioning line are freely arranged out of the operating holes of the supporting tubes; the supporting tubes penetrate in the middle of the tensioning line; and the tensioning line surrounds the tensioning ring by a circle. The traditional negative pressure action mode and a mode of clamping the head and the face of a fetus by using metal forceps are changed, a mode of sleeving the head of the fetus by using the cloth bag and drawing the head of the fetus is adopted, and the head of the fetus cannot be injured. Moreover, the disposable noninvasive cloth bag type obstetric forceps are convenient to operate and can be conveniently popularized and used in batches.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable non-invasive bag-type forceps and a knot pusher. Background technique [0002] Sometimes the help of external force is needed during the normal delivery of the fetus. At present, fetal head suction is generally used for midwifery, but its working principle is to use negative pressure to directly act on the fetal head, and the fetal head is quite fragile. Therefore, the control of negative pressure It is extremely important, if it is too low, it cannot play a role in midwifery, and if it is too high, it may cause damage to the fetal head; there is also a metal forceps that directly acts on the fetal head and face, sometimes causing damage to the soft tissue of the head and face, intracranial hemorrhage, facial paralysis, etc. Complications; Whether there is a better midwifery method is a technical problem that needs to be solved now.
