Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a multifunctional thoracic and abdominal cavity flushing and suction device. Background Art

[0002] With the development of medical technology, thoracic and abdominal surgery occupies an important position in clinical surgical operations. During thoracic and abdominal surgery, in order to keep the surgical field clear and the surgical site clean, it is usually necessary to use a flushing and suction device to flush and suction the surgical site.

[0003] The existing thoracic and abdominal cavity flushing and suction devices have the following problems: First, during thoracic and abdominal cavity surgery, blood clots and adhesions often appear in the surgical site, especially in hidden areas, and these residues are difficult to completely remove by suction alone. The flushing force of the existing flushing device is insufficient and cannot effectively remove these residues, which may lead to postoperative complications.

[0004] Secondly, during the operation, the patient usually takes the supine or lateral position. Due to the effect of gravity, the flushing fluid of the existing flushing device is easily deposited in the lower area, while it is difficult to effectively flush the upper area (anti-gravity area), resulting in uneven cleaning effect.

[0005] Third, existing flushing devices generally use room temperature flushing fluid, which can have an adverse effect on the patient's perioperative recovery. Studies have shown that the surgical process itself can cause trauma to the patient, and factors such as anesthesia and intraoperative fluid infusion may cause hypothermia in the patient. Especially in abdominal surgery, patients are prone to hypothermia and reduced vasoconstriction, which is often accompanied by local tissue ischemia and hypoxia, leading to a series of complications, such as poor wound healing, increased risk of infection, increased oxygen consumption, increased chills, and impaired coagulation function. Summary of the invention

[0006] The purpose of the present invention is to provide a multifunctional chest and abdominal cavity washing and suction device, which can effectively remove surgical site residues, achieve all-round washing, and maintain a constant temperature of the washing fluid.

[0007] To achieve the above object, the present invention is implemented through the following technical solutions:
