Obstetric forceps with function of attaching to infant head

Abstract

The invention discloses obstetric forceps with a function of attaching to an infant head. The obstetric forceps comprise forcep heads and an operation part for controlling open and close of the forcepheads, wherein the forcep heads comprise a first forcep handle and a second forcep handle which are hinged with each other, and the first forcep handle and the second forcep handle are used for clamping the infant head by means of closing. The obstetric forceps are characterized in that a plurality of openings are formed in opposite sides of the first forcep handle and second forcep handle, and aplurality of cavities are formed in the first forcep handle and second forcep handle; a first rubber film, a second rubber film, a second air storage cavity and a liquid storage cavity are arranged in each cavity; the edge of the first rubber film and the edge of the second rubber film are respectively fixed on the inner wall of each cavity; each sealed liquid storage cavity is reserved between the respective first rubber film and the respective second rubber film and is filled with a liquid; each second rubber film is used for separating the respective liquid storage cavity and the respective second air storage cavity; and air pressure in each second air storage cavity can be operated by the operation part.

Description

technical field [0001] The invention relates to the field of obstetrics and gynecology medical instruments. Background technique [0002] Obstetrics and Gynecology is one of the four main disciplines of clinical medicine. It mainly studies the etiology, pathology, diagnosis and prevention of female reproductive organ diseases, the physiological and pathological changes of pregnancy and childbirth, the prevention, diagnosis and treatment of high-risk pregnancy and dystocia, female reproductive endocrinology, Family planning and women's health care. The in-depth study of basic medical theories such as modern molecular biology, oncology, genetics, reproductive endocrinology and immunology and the advancement of clinical medical diagnosis and treatment detection technology have broadened and deepened the development of obstetrics and gynecology, and ensured women's physical and reproductive health. It plays an important role in the prevention and treatment of various obstetrica...

Problems solved by technology

[0004] Aiming at the problem in the prior art that the head of the fetus is easily damaged, the present invention discloses an obstetrics and gynecology forceps that can cling to the head of the fetus. The pincer head includes a first pincer handle and a second pincer handle that are hinged to each other, and the first pincer handle and the second pincer handle clamp the fetal head by closing, and it is characterized in that the first pincer handle and the second pincer handle are opposite to each other. There are several openings on the surface of the clamp, and there are several cavities inside the first tong handle and the second tong handle, and the first rubber membrane, the second rubber membrane, the second air-holding chamber, and the liquid-holding chamber are arranged in the cavity. The edges of the first rubber membrane and the second rubber membrane are respectively fixed on the inner wall of the cavity, and there is a sealed liquid-holding cavity between the first rubber membrane and the second rubber membrane, and a fluid is arranged in the solution cavity, and the second rubber membrane will contain The liquid chamber is isolated from the second air chamber, and the air pressure in the second container chamber can be controlled by the operating part, so that when the air pressure in the second container chamber increases, the second container chamber squeezes the second rubber membrane, and the second rubber membrane It is squeezed and stretched to squeeze the fluid in the solution cavity, and further squeeze the first rubber film to stretch to the outside to form a dispersion layer between the fetal head and the forceps, and the dispersion layer spreads the forceps against the fetal head. clamping force to protect the fetal head
