An assistance device and an associated obstetrical instrument, in particular of the forceps type, for extracting a fetus during childbirth having two branches. Each branch being equipped at one end with a gripping handle and at the other end with cephalic blades. The instrument further includes a measurement device using the blades and connector between the measurement device and the blade. The measurement device includes: a pressure measurement instrument configured to measure the pressure exerted by the blade on the fetus, a position measuring instrument to measure the positioning of the obstetrical instrument, a power supply, and a transmitter configured to transmit the measurements to a processing unit.

A regulator diameter device to extract an element that is inside a cavity, which is introduced together with a flexible sleeve and an applicator, which comprises an adjustment strip of flexible material; and at least of a mean to regulate said diameter, with the adjustment strip open. The means to regulate such strip: a hollow case with a distal end and a proximal end, fixed to one of the traction handles, at least one string passes through this case, in which the distal ends of the at least one string, are fixed to the open ends of the adjustment strip, while the proximal ends of the string are fixed to a pulling system. The method of use of regulator diameter device to extract an element that is inside a cavity comprises the following steps: a. Introduce the combination (regulator device and the applicator) inside the cavity until the applicators' cup makes its first contact with the element to be extracted; b) go on pushing the combination which will open the distal ends of the applicator tentacles; c) once the mayor area of the element to be extracted is passed a first regulation of the adjustment strip is done, pulling the trigger and blocking it in this new position; d) keep on pushing until the final insertion; e) regulate again the adjustment strip until its final measure, being able to measure the diameter of the element to be extracted, which can be read in the pulling system scale; f) inflate the air chamber if the device has one; g) remove the applicator; h) pull the traction handles to extract the element that is inside the cavity.

An obstetric apparatus and method for repositioning a fetal head within the birth canal of a woman in labor. A user, typically an obstetrician, surgeon or similarly trained medical personnel, can efficiently and safely engage a fetal head that is wedged in the parturient woman's pelvis and lift it up in the birth canal towards the uterus, for safe delivery of the baby via C-section. The apparatus comprises an elongated and substantially rigid shaft, a pivoting neck and a soft engaging portion that includes a flexible outer cup and an inflatable inner cup for engaging the fetal head. The inventive apparatus and method can provide a mechanical advantage for repositioning the head of the fetus, and can provide assistance for C-section delivery in order to minimize maternal and neonatal complications.

An obstetrical instrument includes an elongated handle and a fetal head support portion coupled with a distal end of the elongated handle.

A surgical device, and related method to aid in delivery by vaginal or cesarean section delivery to dislodge the fetal head when it has become wedged in the birth canal is provided. The device has a body and a handle for an operator to hold and brace against the mother, and a head plate with an inflatable bladder for gently applying force to the fetal head. The head plate is inserted into the birth canal and the bladder is filled with air or biocompatible fluid. The combination of insertion and inflation gently elevates the fetal head out of the birth canal into the pelvis to facilitate repositioning or extraction of the fetus. The device may have an adjustable neck to accommodate different anatomies and scenarios. The device may have sensors to monitor the health of both the neonate and the mother and to aid in the operation of the device.

Disclosed is a device for detecting a pressure, of the type including a detection element on which a pressure is exerted, a transducer connected to the detection element and an elastically deformable shell. The shell is made of biocompatible and sterilizable material, has two opposing walls and an insertion opening, and the detection element includes at least one elastically deformable tube, the tube includes a portion arranged in the shell, the tube is closed at one end and filled with a fluid, the other end of the tube being open, arranged outside the shell and connected to the transducer.
