Abstract

Abstract Process for rotation of the fetal head during childbirth, using a force through the agency of spatulas by applying the principle of wheel rotation, namely for rotating the head in any of its presentations of position, to reduce fetal and maternal lesions, as well as the necessity of cesarean sections, and to facilitate manipulation by less skilled personnel; the process comprising rotating the head by applying the force at a point corresponding to the zone of the occipital bone, utilizing the axis of rotation which passes through the junction of the cervical column with the fetal occiput, and using the spatulas of specific shapes. An instrument is also disclosed for the rotation of the fetal head, comprising a pistol-grip handle, and a pedical terminating in a solid scoop, the latter presenting a pelvic curvature and a cephalic curvature, the axis of the tip of the scoop having a specific angular inclination relative to the longitudinal axis of the instrument.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 97 words
A process for rotation of the fetal head during childbirth, comprising the steps of: using a force through the agency of spatulas by applying the principle of wheel rotation for rotating the head in any of its presentations of position, to reduce fetal and maternal lesions, as well as the necessity of cesarean sections; rotating the head by applying the force at a point corresponding to the zone of the occipital bone; and utilizing as the axis of rotation, the rotation axis of the head passing through the junction of the cervical column with the fetal occiput.
Claim 2
Dependent Claim 97 words
A process for rotation of the fetal head during childbirth, comprising the steps of: using a force through the agency of spatulas by applying the principle of wheel rotation for rotating the head in any of its presentations of position, to reduce fetal and maternal lesions, as well as the necessity of cesarean sections; rotating the head by applying the force at a point corresponding to the zone of the occipital bone; and utilizing as the axis of rotation, the rotation axis of the head passing through the junction of the cervical column with the fetal occiput.
Claim 3
Dependent Claim 40 words
The process as defined in claim 1, utilizing a spatula having a handgrip and scoop and pedicle portions and further comprising the step of inserting the spatula in the side of the maternal pelvis that corresponds to the fetal occiput.
Claim 4
Dependent Claim 69 words
The process as defined in claim 2, for situations where the head is not visible during the uterine contraction after the inserting step, further comprising the steps of holding the handgrip of the spatula in one hand with the scoop in lateral positional presentation with respect to the fetal head, and depressing the perineum by the other hand, in order to effect rotation with view of the fetal head.
Claim 5
Dependent Claim 101 words
The process as defined in claim 2, for situations where the fetal head is visible during the uterine contraction after the inserting step, further comprising the steps of taking the handgrip of the spatula in one hand with the scoop in lateral positional presentation with respect to the fetal head, and resting the other hand on the proximal portion of the scoop portion of the spatula and part of the pedicle portion thereof, in such a manner that on the occurrence of the uterine contraction there will be an area of close contact between the scoop portion and the fetal head.
