Problems solved by technology

However, there are still many unfavorable factors in this membrane rupture device: first, the fetal membrane is sucked by negative pressure, and the fetal membrane must be absorbed to the depth of the cylinder before it can be punctured by the membrane needle, and medical personnel need great strength; Second, the fetal membrane needle is set at the side end of the syringe, and the fetal membrane may not be able to touch the fetal membrane needle and rupture after inhalation, that is, the probability of the fetal membrane needle damaging the fetal membrane is not 100%, and medical staff may fail to rupture the membrane. situation, requiring repeated membrane rupture

Embodiment Construction

[0032] Below with the accompanying drawings Figure 1 to Figure 9 Describe in detail.

[0033] The fetal membrane in the present invention may be called membrane or amniotic membrane. The invention is applicable not only to the rupture of membranes, but also to the rupture of membrane-like tissues of human or animal tissues. The present invention can also be a membrane rupture device for animal fetal membranes.

[0034] Rupturing needle, a needle-shaped part suitable for rupture of membranes, having a tip capable of rupturing membranes. Preferably, the rupture needle can be a common needle or a needle with multiple edges. The length setting direction of the blade is parallel to the axial direction of the needle. The direction of the blade is radial to the needle. The invention provides an obstetric membrane rupture device, such as image 3 As shown, the rupture device at least includes an outer cylinder 1 , at least one rupture needle 4 disposed on the wall of the outer ...

Abstract

The invention relates to an obstetrical membrane rupture device which at least comprises an outer cylinder (1), at least one membrane rupture needle (4) arranged on the wall portion of the outer cylinder (1) and a membrane fixing assembly (5) fixed to a push rod (3) in a spiral rotating mode by penetrating through a piston (32). The fixed film assembly comprises a fixed film ball (51) and a ball seat (52), a plurality of meshing edges are arranged on the surface of the fixed film ball (51), the ball seat (52) is connected with the fixed film ball (51) in a rotatable mode, and under the condition that the push rod (3) drives the piston (32) to move and negative pressure is formed in the outer cylinder (1), a plurality of occlusion edges on the surface of the membrane fixing ball (51) move the fetal membrane in contact with the occlusion edges based on the rotation trend of the membrane fixing ball (51), so that part of the fetal membrane moves, is in contact with the fetal membrane needle (4) and is broken. The fetal membrane can be ruptured only through small negative pressure and shallow fetal membrane suction depth, convenience and rapidness are achieved, and the strength of medical staff is saved.

Description

technical field [0001] The invention relates to the technical field of gynecological medical instruments, in particular to an obstetric membrane rupture device. Background technique [0002] Artificial rupture of membranes is one of the common medical interventions used in obstetrics and gynecology to promote the labor process. There are no special instruments for artificial membrane rupture in obstetrics and gynecology. Obstetricians usually use needles or vascular forceps to perform artificial rupture of membranes. At present, the existing membrane rupture devices can be used in conjunction with gynecological surgery, but in actual use, the current membrane rupture tools are mainly puncture needles, which is very inconvenient for doctors to operate with puncture needles, and requires relatively high technical proficiency for doctors , and the depth of the puncture of the fetal membranes is not easy to grasp, the puncture depth is too deep may damage the fetus, and the punc...
