Description

A fetal head suction type forceps delivery device

technical field

The application relates to a fetal head suction forceps device, which belongs to the technical field of medical devices.

Background technique

Forceps midwifery is one of the important means to solve cephalic dystocia, shorten the second stage of labor, and terminate pregnancy as soon as possible. However, the commonly used forceps in clinical practice (Simpson forceps, Kielland forceps) have very high requirements on the experience of doctors. The operating physician must clearly understand the fetal position. Improper placement of forceps may cause neonatal facial injuries, neonatal asphyxia, intracranial hemorrhage, etc. . In addition, the forceps themselves are large in size and occupy a certain amount of space on the side wall of the pelvis. During use, it is easy to cause severe laceration and bleeding of the mother's vagina and perineum. Therefore, be badly in need of a kind of midwifery forceps device that can be easy to operate, be easy to grasp and reduce maternal and infant injury clinically, complete smooth childbirth as soon as possible.

Utility model content

The purpose of this application is to provide a clinically easy-to-operate midwifery device to improve the success rate of forceps midwifery.

In order to solve the above technical problems, the technical solution of the present application is to provide a fetal head suction type forceps delivery device, which is characterized in that it includes a pair of opened forceps leaves, a hinged control handle for controlling the opening angle of the forceps leaves, and a The middle negative pressure suction disc in the middle of the leaf, the forceps leaf is provided with a negative pressure hole, the negative pressure hole is connected to the negative pressure device through a hose, and the middle negative pressure suction disc is connected to the negative pressure device; The negative pressure suction disk and the two forceps blades are adsorbed on the fetal head by negative pressure to form a triangular adsorption.

Wherein, the intermediate negative pressure suction disc is connected to the negative pressure device through a hollow column, and the hollow column is fixed to the hinge shaft of the hinged control handle.

Preferably, the forceps leaves are set as flexible forceps leaves.

This application combines negative pressure suction and flexible forceps structure to make forceps midwifery actions more stable, minimize maternal and infant injuries during forceps midwifery delivery, and improve the success rate of forceps midwifery. The advantages lie in:

1. The fetal head suction type forceps device has reasonable design, simple structure, safety and reliability, convenient use and easy maintenance, and has good promotion and use value.

2. The fetal head suction type forceps device greatly reduces maternal and infant injuries, and is easy for beginners to learn to use.

3. After the fetal head suction type forceps device is fixed, the operator only needs to pull it with one hand, and the other hand can protect the perineum at the same time. The midwifery process can be completed by one person without the help of an assistant.

Description of drawings

The structural schematic diagram of the fetal head suction type forceps delivery device provided in the embodiment of Fig. 1 .

detailed description

In order to make the application clearer and easier to understand, preferred embodiments are described in detail below with accompanying drawings.

Example

What this embodiment provides is the fetal head suction forceps device, as shown in Figure 1, including a pair of opened forceps leaves 1, a hinged control handle 4 for controlling the opening angle of the forceps leaves 1, and an intermediate load in the middle of the forceps leaves 1. The pressure suction disc 3, the middle negative pressure suction disc 3 is connected with the hollow column 5, the hinge shaft of the hollow column 5 and the hinged control handle 4 is fixed, the middle negative pressure suction disc 3 is connected to the negative pressure device through the hollow column 5; A negative pressure hole 2 is provided, and the negative pressure hole 2 is connected to the negative pressure device through a hose;

The middle negative pressure suction disk 3 is adsorbed on the fetal head by negative pressure, and the forceps leaf 1 is set as a flexible forceps leaf that is adsorbed on both sides of the fetal head by negative pressure; the middle negative pressure suction disk 3 cooperates with the forceps leaf 1 to form a stable structure of triangular adsorption.

The steps to use this device are as follows:

Step 1: Pre-operation preparations such as routine disinfection and draping, vaginal examination, clear fetal position, whether there are conditions for forceps midwifery, local perineal block anesthesia;

Step 2: Check whether the central negative pressure suction disk 3 device is leaking, and perform episiotomy if necessary. Place the fetal head suction forceps device so that the open end of the central negative pressure suction disc 3 circles around the fetal head presentation; place the left lobe forceps, and place the flexible forceps leaf on the left side of the mother's pelvis, close to the temporal part of the fetus; In the same way, guide the right forceps to be placed on the right side of the pelvis, so that the left and right forceps are correspondingly buckled;

Step 3: Set the negative pressure so that the negative pressure suction disk 3 in the middle and the forceps leaves 1 on both sides are all adsorbed on the fetal head;

Step 4: Stretch, delay the uterine contraction and pull downward in the direction of the production axis. If the head position is not correct, pull it while rotating, so that the fetal head turns to the anterior position; stop the operation when the uterine contraction stops, and wait until the next uterine contraction begins Re-traction helps the fetal head to complete flexion and extension. When the fetal head is extended, the negative pressure is released, and the suction forceps device automatically falls off. Subsequent routine delivery steps.

This application uses the middle suction plate and the forceps leaves on both sides to form a triangular stable structure, which makes the forceps midwifery action more stable and reduces the instability of forceps falling off during forceps; different from traditional metal forceps leaves, traditional metal forceps has high requirements for operating doctors , and cause a high risk of maternal and fetal injury. The front end of the forceps of this device is made of soft material, which can fit well the temporal part of the fetal head, making the forceps itself easy to place, and reducing the damage to the mother's birth canal, and at the same time reducing the damage to the baby's face , Reduce forceps slippage caused by friction with fetal facial tissue. The material of the first half of the forceps is provided with air holes, which are connected to negative pressure. When in use, the bilateral forceps leaves are fixed by the force of negative pressure suction; at the same time, they are pulled outward by the force of the forceps suction; both the fetal head suction and forceps leaf devices are connected with negative The pressure gauge can control the negative pressure very well.
