Abstract

The obstetrical rupturing membrane device comprises a sleeve, wherein one end of the sleeve is provided with two arc-formed strips, a torsional spring is arranged between the arc-formed strips and the articulated shaft, and two ends of the torsional spring are respectively connected with the arc-formed strips and the sleeve, the torsional spring gives an outward force to the arc-formed strips all along; the other end of the arc-formed strip is connected with one side of a tie line, and the other side of the tie line is placed behind the rear-end of the sleeve; the rear-end of the sleeve is provided with an end cover with a through-hole, and then a screw provided with nuts passes through the through-hole, the other side of the tie line is connected with the nuts which lies the outside of the end cover; the interior of the sleeve is provided with a plurality of bearing mounts, and also provided with a rotary rod which is connected and cooperated with the bearing mounts by a bearing; the front end of the rotary rod is provided with a cutter head lying on the front end of the sleeve; the rear perimeter of the rotary rod is provided with external screw threads, and the external screw threads of the rotary rod are provided with screw shell. The obstetrical rupturing membrane device can avoid scratching embryos during the process of rupturing membrane, and the device is easier to get in and out of the birth canal.

Description

technical field [0001] The invention belongs to the field of obstetric equipment, in particular to an obstetric membrane rupturer. Background technique [0002] At present, in the membrane rupturer used in obstetrics, a cover is provided at the end of the membrane rupturer to prevent the cutting head from being inserted too deep and scratching the fetus during membrane rupture. However, due to the large diameter of the end cover body, the resistance is relatively large when inserted into the birth canal of the puerpera, which is inconvenient to use. Contents of the invention [0003] The invention provides an obstetric membrane rupturer to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] The obstetric membrane rupture device includes a sleeve. The front end of the sleeve is provided with two arc bars. One end of the arc bar is hinged with the sleeve. A torsion spring is provided at the hing...
