HERMETIC OCCLUSION SURGICAL CLAMP FOR THE CERVIX IN CASES OF PLACENTA PRAEVIA

The present application comprises a hermetic occlusion surgical clamp for the cervix for use in cases of placenta praevia, which comprises: Jaws, which includes a compression spring expander, (5.1) at one end of each jaw has a semi-conical section (5.2) and furthermore each section has a semi cylinder (5.3) drilling, which overlap mutually, and are joined with a pin (5.4) the traction cylinder, a wheel cylinder, which has a semi elliptical machining (6.1) sufficient to accommodate the half-cylinders (5.3) of the jaws, said machining generates two arms (6.2) which each have a bore, in which is assembled the bolt (5.4) that allows holding the half-cylinders (5.3) of the jaws, with the pulling cylinder, which allows rotation of the jaws about the bolt shaft ( 5.4) on the outside of the same end is machined a groove (6.3) which engages the pin of the shell (7.1) which is located inside of said shell, this coupling prevents rotation of the jaws about the longitudinal axis of pulling cylind er when the drive cylinder is ensamblad the breastplate, at the thread (6.4) of the drive cylinder, allowing screwing a nut (6.5) same as to be rotated to open or close the jaws when the jaws are assembled, the wheel cylinder and the Breastplate. A shell, which is a hollow cylinder all along its longitudinal axis, which covers from semi conical sections (5.2) of the jaws, to leave a length of thread (6.4) allowing free positioning of the nut (6.5 ), said shell, at one of its end has a conical section (7.2), whose inner part are coupled approximation of the jaws, rotating the nut (6.5) in either direction, on the inside of the shell, housing the bolt shell (7.1). The present clamp is considered as an invention since there is no surgical clamp currently available on the market specifically designed for avoiding blood leakage through the duct during the operation of a patient with placenta previa bleeding. Women may die of torrential bleeding. La presente invención propone una pinza quirúrgica de oclusión hermética para el cuello de la matriz femenina para usarse en casos de placenta previa, que comprende de: Unas mordazas, figura 5, compresivas las cuales incluye un resorte expansor, (5.1); en uno de los extremo de cada mordaza tiene un sección semi cónica (5.2) y además cada sección tiene un semi cilindro (5.3) barrenado, que se traslapan mutuamente, y se unen con un perno (5.4) al cilindro de tracción, figura 6; Un Cilindro de Tracción, figura 6, el cual tiene maquinado un es
