Description

Technical Field

[0001] The utility model relates to the technical field of exhaust equipment, in particular to an endoscopic surgery abdominal cavity exhaust device. Background Art

[0002] During the endoscopic treatment process, due to lesion reasons (full-thickness tumor body) or operation reasons, active or passive perforation may occur. After perforation, not only will the abdominal cavity pressure of the patient increase, the diaphragm will move upward, and the patient's heart rate and breathing will be affected, but also the gastrointestinal cavity will be squeezed, resulting in poor endoscopic surgery vision, and ultimately leading to the termination of the endoscopic surgery. Therefore, exhaust operation is required.

[0003] It is found in daily work that when most patients need to exhaust the abdominal cavity, they often puncture with a syringe needle for exhaust. During the operation process, the needle is prone to blockage, and repeated punctures are required, which is likely to cause pollution at the puncture site and result in abdominal cavity infection of the patient. Therefore, improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that when most patients need to exhaust the abdominal cavity, they often puncture with a syringe needle for exhaust. During the operation process, the needle is prone to blockage, and repeated punctures are required, which is likely to cause pollution at the puncture site and result in abdominal cavity infection of the patient, and an endoscopic surgery abdominal cavity exhaust device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an endoscopic surgery abdominal cavity exhaust device, including a catheter and an exhaust assembly. The exhaust assembly is arranged at one end of the catheter. The exhaust assembly includes a Y-shaped connector. A stylet is installed at one end of the catheter. The Y-shaped connector is fixedly connected to one end of the catheter. A communication valve is fixedly connected to the end of the Y-shaped connector away from the catheter. Through the exhaust device, it is convenient to discharge the gas in the patient's abdominal cavity. After leaving this device, the purpose of continuous exhaust can be achieved, which is convenient for popularization and use.

[0006] Preferably, a socket is fixedly connected to one side of the communication valve. A syringe barrel is inserted into the socket. A pull rod is slidably connected inside the syringe barrel. When the abdominal cavity pressure of the patient is too high, the syringe barrel can be inserted into the socket, then the communication valve is rotated, then the pull rod is pulled outwards, and then the pull rod cooperates with the syringe barrel to extract the gas in the patient's body. After completing a single exhaust, the communication valve is rotated to close, and then the syringe barrel is pulled out to discharge the internal gas.

[0007] Preferably, a clamp for adjusting the flow rate inside the catheter is provided on the catheter, which can clamp the catheter. When the intra-abdominal pressure of the patient is too high, the syringe can be inserted into the insertion port, then the communication valve is rotated, and then the pulling rod is pulled outwards. Subsequently, the pulling rod cooperates with the syringe to extract the gas in the patient's body. After a single exhaust, the communication valve is rotated to close, then the syringe is pulled out, and the internal gas is discharged. Through the exhaust device, it is convenient to discharge the gas in the patient's abdominal cavity, reducing the workload of medical staff. At the same time, this solution can be reused, reducing the risk of wound infection and facilitating popularization and use.

[0008] Preferably, a protective component is provided on the surface of the other end of the catheter. Through the protective component, it is convenient to perform protective operations on the catheter, reducing the situation that the catheter is deformed due to being squeezed during use, ensuring the smoothness of the catheter, and facilitating the normal operation of the equipment.

[0009] Preferably, the protective component includes a support cylinder and a breathable tape. The support cylinder is sleeved on the surface of the other end of the catheter, and the breathable tape is located on the upper surface of the support cylinder and is connected to the surface of the support cylinder.

[0010] Preferably, a bottom plate is fixedly connected to the lower surface of the support cylinder, which is convenient for stably supporting the support cylinder. Through the protective component, it is convenient to perform protective operations on the catheter, reducing the situation that the catheter is deformed due to being squeezed during use, ensuring the smoothness of the catheter, and facilitating the normal operation of the equipment.

[0011] Preferably, a magic male sticker or a magic female sticker is fixedly connected to the lower surface of the breathable tape, and a magic female sticker or a magic male sticker is fixedly connected to the upper surface of the support cylinder. The magic male sticker and the magic female sticker are adhesively bonded to each other. Before connecting the catheter, the support cylinder is sleeved on the catheter, then the catheter is inserted into the patient's body, then the bottom plate on the support cylinder is attached to the patient's body surface, then the magic male sticker on the breathable tape is attached to the magic female sticker on the support cylinder, and then the breathable tape is attached to the patient's surface.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, when the intra-abdominal pressure of the patient is too high, first, the catheter is driven through the abdominal wall by the needle core and enters the abdominal cavity, and then the needle core is withdrawn, so that only a section of the catheter remains in the abdominal cavity. The syringe can be inserted into the insertion port, then the communication valve is rotated, and then the pulling rod is pulled outwards. Subsequently, the pulling rod cooperates with the syringe to extract the gas in the patient's body. After a single exhaust, the communication valve is rotated to close, then the syringe is pulled out, and the internal gas is discharged. Through the exhaust device, it is convenient to discharge the gas in the patient's abdominal cavity. After leaving this device in place, the purpose of continuous exhaust can be achieved, which is convenient for popularization and use.

[0014] 2. In the present utility model, before connecting the catheter, the support cylinder is sleeved on the catheter, and then the catheter is inserted into the patient's body. Subsequently, the bottom plate on the support cylinder is attached to the patient's body surface. Then, the male magic tape on the breathable tape is attached to the female magic tape on the support cylinder, and then the breathable tape is attached to the patient's surface. Through the protection component, it is convenient to perform protection operations on the catheter, reduce the deformation of the catheter caused by force extrusion during use, ensure the patency of the catheter, and facilitate the normal operation of the equipment.
