[0001] The invention belongs to the technical field of medical devices, in particular to a special membrane-rupturing needle for obstetrics. Background technique

[0002] At present, when performing artificial rupture of membranes in obstetrics, obstetricians often use needles or vascular forceps to rupture membranes according to their own working habits and experience. When using needles to rupture membranes, they usually hold the needle between the middle finger and index finger The accuracy of this operation is poor and the stability is not high, especially when the cervix is ​​less than 30 mm; when using vascular forceps for artificial membrane rupture, because the length of the vascular forceps is limited, and the vascular forceps The top of the breast is relatively blunt, and the fetal membrane needs to be clamped to tear it. This operation is difficult to control the size of the tear, which adds great difficulty to the specific operation of the obste...
