Description
Technical Field
The invention belongs to the field of medical instruments for birth control, and particularly relates to obstetric forceps for obstetrical surgery.
Background
The obstetric forceps midwifery is an effective midwifery operation mode commonly used by obstetrics for natural delivery difficulty or cesarean delivery difficulty. The obstetric forceps are a common surgical tool for traction, correcting the orientation of the fetal head, assisting the delivery of the fetus and shortening the second labor stage. The obstetric forceps are suitable for the conditions that the opening of the uterine orifice is full and the position of the fetal head is lower in natural delivery, and are generally used for the conditions that the uterus is weak, the position of the fetal head is abnormal, the second labor stage is prolonged or the fetal intrauterine distress occurs in the second labor stage. The obstetric forceps for caesarean section is an important auxiliary instrument for solving the problem of head delivery difficulty in caesarean section, and can enable a fetus to be delivered as soon as possible by the obstetric forceps delivery assisting operation when the fetal head is high and floating or embedded too deeply in the caesarean section, especially when the fetus is bigger, the fetal head cannot be delivered in time, amniotic fluid is sucked, the newborn baby is suffocated and the like. The obstetric forceps for delivery can effectively improve the success rate of natural delivery of the puerpera, reduce the damage to the neonate and the puerpera during delivery, accelerate the delivery speed of the fetus delivered by caesarean section, do not need to add abdominal pressure, and is very effective for the people who have delivery head difficulties or the puerpera with serious pregnancy complications and need to rapidly deliver the fetus.
The obstetric forceps are basically characterized in that the forceps are short in diameter, light and flexible to operate, the forceps are divided into two leaves, the size of a fetal head is formed between the two leaves, and a space similar to the shape of the fetal head is formed between the two leaves, so that the fetal head is firmly held by the obstetric forceps leaves and is surrounded and protected by the fetal head, the fetal head is prevented from being extruded, a midwife holds the forceps handle by hand, and the forceps are slightly pulled outwards to help the delivery of the fetal head. Traditional obstetric forceps, the material is stainless steel, nevertheless about the combination in-process need about the use of collocation behind the two leaves lock, and about the two leaves again be difficult to the identification to there are two edges and corners that show handle lower extreme, cause secondary damage to the lying-in woman easily, the handle is straight smooth, easy out of hand, the anterior part hardness of obstetric forceps is too big, very easily to the unnecessary damage that causes of neonate.
According to statistics, in all delivery modes, the probability of birth injury is highest by virtue of delivery forceps delivery assistance, wherein the birth injury of a newborn is accidental injury to the newborn in delivery or operation delivery assistance, the birth injury is caused by mechanical factors, if the delivery assistance is improper during delivery difficult, a light person can cause head and face skin abrasion of the newborn, and a heavy person can cause eyeball injury, skull fracture, craniofacial blood squeezing, facial nerve paralysis, brachial plexus nerve injury and other consequences of the newborn.
Disclosure of Invention
The invention aims to provide obstetric forceps for obstetrical surgery, which are not easy to damage a fetus and are relatively safe.
The technical scheme adopted by the invention is as follows: the utility model provides an obstetric forceps for obstetrical surgery, includes two mutual articulated handles of tip, and every handle articulated one end is equipped with the pincers palm, is equipped with titanium nickel alloy memory wire in every pincers palm, and titanium nickel alloy memory wire is the line structure at low temperature looks, and titanium nickel alloy memory wire produces the expansion that is used for the pincers palm at high temperature looks deformation, and one side of every handle all is equipped with the control by temperature change heater, and titanium nickel alloy memory wire connects the control by temperature change heater.
The two handles are hinged through a combination buckle.
One end of the titanium-nickel alloy memory wire is fixedly connected to the combination buckle, and the other end of the titanium-nickel alloy memory wire surrounds the inner circumference of the forceps palm, extends into the handle and extends out of the handle.
The digital camera is fixedly connected to the outer portion of the inner side of one of the clamp palms, a connecting wire is arranged on the digital camera, one end of the connecting wire sequentially penetrates through the clamp palms and the handle and extends to the outer portion of the handle, and a USB interface is arranged on the connecting wire positioned outside the handle.
The two clamp palms are respectively sleeved with a silica gel sleeve, and the silica gel sleeve arranged on one side of the digital camera is provided with a side hole for placing the digital camera.
The control temperature range of the temperature control heater is 35-38 ℃.
The invention has the beneficial effects that: according to the invention, the silica gel protective sleeve is sleeved outside the forceps palm, and the silica gel protective sleeve is soft, so that not only can the damage to a newborn in the delivery assisting process be avoided, but also the secondary damage to the parturient can be avoided; the temperature of the temperature control heater is set to be 35-38 ℃, the temperature can enable the titanium-nickel alloy memory wire to deform to hold the head-up in the palm of the pliers, and the temperature range is close to the temperature of a human body and can be accepted by a newborn; according to the invention, the digital camera is arranged and can be connected with the external display through the USB interface, so that the production process and the condition of the newborn can be observed at any time. The invention has simple structure and can effectively help the parturient to produce.
