Description

Abdominal opening and closing device

Technical field

The invention relates to the field of medical instruments, in particular to an abdominal opening and closing device.

Background technique

In wartime emergencies, due to limited conditions, the soldiers who have abdominal injuries can open the abdominal cavity for simple treatment, but for the surgical mouth of the abdominal cavity, there is no effective emergency treatment, that is, the soldiers’ vital signs cannot be maintained. There is no guarantee that the soldiers will be safely delivered for further treatment. At this stage, in emergency situations such as the battlefield, most of them use a pair of pliers clips to temporarily clamp the surgical incision, which not only increases the pain of the soldiers, but also easily causes wound infection, and it is also difficult to observe the situation in the abdominal cavity.

In surgery, it is often the case that uncertain surgery requires repeated multiple operations in the abdominal cavity, such as severe pancreatitis surgery. The traditional method is to suture the surgical wound repeatedly, or to use gauze and other stuffing, which not only increases the difficulty of the operation, but also increases the pain of the patient, and the wound after the suture, the doctor can not observe the condition of the lesion, often occurs in the vital signs of the patient. After the change, it can be found that the patient's risk increases.

In summary, the existing practices have the following drawbacks:

1. The operation is time consuming and laborious, and requires repeated surgical operations to cause great pain to the patient and increase the risk of infection of the patient;

2. The patient usually has a high abdominal pressure, and the traditional practice does not give the patient a corresponding space for releasing the abdominal pressure, thus causing discomfort to the patient;

3. Many uncertain operations need to monitor the development of the patient's intra-abdominal condition from time to time, and grasp the timing of the second operation according to the condition of the time. The traditional practice can not observe the changes of the body condition anytime and anywhere. Therefore, the timing of the surgery cannot be well grasped.

Summary of the invention

It is an object of the present invention to provide an abdominal opening and closing device which can open and close the abdominal cavity at any time without a surgical operation, can release abdominal pressure, and can observe the internal condition of the abdominal cavity at any time.

The invention is realized by the following technical solution: a peritoneal opening and closing device, characterized in that it comprises a first fixing ring, a second fixing ring and a sealing switch device;

The first fixed ring and the second fixed ring are sequentially arranged from top to bottom, and the first transparent ring and the second fixed ring are provided with a first transparent film structure, and the upper edge and the lower edge of the first transparent film structure are respectively Sealing connection with the first fixed ring and the second fixed ring;

The second transparent film structure is covered with the second transparent film structure, the second transparent film structure is sealingly connected with the first fixing ring, and the second transparent film structure is provided with the first opening and the edge of the first opening and the sealing switch The device is sealed.

Compared with the prior art, the beneficial effects of the present invention are:

1. Completely change the way of opening and closing the abdominal incision through surgical operation, and use the sealed switch device for non-surgical opening and closing, which greatly reduces the difficulty of operation, reduces the suffering of patients, and reduces the risk of infection;

2. There is a certain confined space between the sealed switch device and the first fixed ring, due to the space and surgery The wound is directly connected, so it can effectively buffer the pressure in the abdominal cavity;

detailed description

The present invention will be described in detail below with reference to the accompanying drawings:

Example 1:

As shown in FIG. 1 to FIG. 4, the present invention includes a first fixed ring 1, a second fixed ring 2, and a sealed switch device;

The first fixed ring 1 and the second fixed ring 2 are sequentially arranged from top to bottom, and a first transparent film structure 8 is disposed between the first fixed ring 1 and the second fixed ring 2, and the first transparent film structure 8 is The upper edge and the lower edge are respectively sealedly connected to the first fixing ring 1 and the second fixing ring 2;

The second transparent film structure 9 is tightly connected to the first fixed ring, and the second transparent film structure 9 is provided with a first opening and an edge of the first opening. Sealed connection with the sealed switchgear.

Further, the sealed switch device includes a rotating sealing ring 4, a fixed sealing ring 6 and a third film structure 10;

The fixed sealing ring 6 is located below the rotating sealing ring 4, and the edge of the first opening of the second transparent film structure 9 is sealingly connected to the fixed sealing ring 6;

The third film structure 10 is disposed between the rotating sealing ring 4 and the fixed sealing ring 6. The upper edge and the lower edge of the third film structure 10 are respectively sealedly connected with the rotating sealing ring 4 and the fixed sealing ring 6; the rotating sealing ring After the rotation, the inner walls of the third film structure 10 can be brought into contact with each other to form a sealing opening.

Here, the first fixing ring 1, the second fixing ring 2 and the first transparent film structure 8 therebetween constitute a surgical opening fixing assembly; when installed, the first fixing ring 1 and the second fixing ring 2 are respectively placed at At the surgical opening inside and outside the abdominal cavity, the two fixing rings and the first transparent membrane structure 8 between them form a clamping action on the abdominal wall and are fixed on the abdominal cavity to construct a surgical opening having a stable shape and structure.

At the same time, the fixed sealing ring 6 is located above the first fixed ring 1 and through the second transparent film structure 9 to construct a closed decompression space. The decompression space is in communication with the underlying surgical opening, so that when the pressure in the abdominal cavity becomes greater, the tissue or tissue fluid in the abdominal cavity is released into the decompression space, which can alleviate the suffering of the patient, and at the same time Observed by medical personnel; and the prejudice of previous medical treatments always suppresses abdominal pressure, which is treated by filling, plugging, plugging or the like, which increases the pain of the patient and the abdominal pressure is too large. When the tissue or tissue fluid in the abdominal cavity is also easily spilled from the surgical opening, the infection is caused.

The rotary seal ring 4 opens and closes the connecting membrane channel by rotating the third membrane structure 10, and is used as a switch for non-surgical opening and closing surgical wounds, allowing the medical staff's arms to extend into the interior for surgery during the operation. At the same time, after the end of the operation, the rotary sealing ring 4 is rotated in one direction so that the inner walls of the third membrane structure 10 are adhered to each other to form a sealing port, and then fixed by a medically common fixing member, so that the opening is completely closed to ensure that the surgical opening is always at the time. The state of isolation from the outside prevents wound infection after surgery. For example, clips, medical tapes, card strips, etc. can be used as fixings.

The embodiment is simple and convenient to use. When operating, the embodiment is placed directly into the surgical opening, and the second fixing ring 2 is placed inside the abdominal cavity to be fixed, and the tissue near the surgical opening is automatically tightened under the action of its own elasticity. The sealing effect is achieved on the retaining ring. At the same time, in order to avoid infection in the contact area, it is further possible to apply antibacterial isolation drugs, such as petrolatum, biogel, etc., to the edge of the first fixed ring 1 to further achieve anti-infection effects.

Here, the second transparent film structure 9 usually has a certain elasticity so as to better accommodate the dirt overflowing in the abdominal cavity.

Further, it further comprises an integrated monitoring sensor mounted on the first fixed ring 1 or the second fixed ring 2 or the first transparent film structure 8.

The integrated monitoring sensor integrates many vital signs electronic sensing elements, such as blood glucose, blood oxygen, abdominal pressure and other sensing elements. Thereby, the auxiliary medical staff monitors the patient's physical condition from time to time.

Further, the shape of the first fixed ring 1 and the second fixed ring 2 is elliptical.

The oval fixing ring can better withstand the pressure exerted by the abdominal wall and maintain the stability of the surgical opening shape.

Further, the first transparent film structure 8 and the second transparent film structure 9 are made of a waterproof fog material.

Because the abdominal cavity is very warm and humid, water mist is easily generated on the inner surfaces of the first transparent membrane structure 8 and the second transparent membrane structure 9 to affect the visual line of the medical personnel to observe the inside of the patient's abdominal cavity, and is made of waterproof fog material. The first transparent film structure 8 and the second transparent film structure can well overcome this drawback.
