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

[0042] Below with the accompanying drawings Figure 1 to Figure 9 Describe in detail.

[0043] 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.

[0044] 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.

[0045] The invention provides an obstetric membrane rupture device, such as Figures 1 to 3 As shown, the rupture device at least includes an outer cylinder 1 , at least one rupture needle 4 disposed on the wa...

Abstract

The invention relates to an obstetric membrane rupture device, which is characterized in that the membrane rupture device at least includes an outer cylinder (1), at least one membrane rupture needle (4) arranged on the wall of the outer cylinder (1), and a penetrating piston (32) The fixed membrane assembly (5) fixed in a helical rotation manner with the push rod (3), wherein the piston (32) moves so that the fetal membrane enters the inner cylinder based on the effect of negative pressure, and the fixed membrane assembly (5) In the process of rotating, it is in contact with the fetal membrane, so that part of the fetal membrane rotates with the fixed membrane assembly and ruptures in contact with the rupture needle (4). The invention only needs a small negative pressure, and the shallow membrane suction depth can realize the rupture of the membrane, which is convenient and quick, and saves the strength of the medical staff.

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...
