Description

Technical Field

[0001] The utility model belongs to the field of medical auxiliary instruments, and in particular relates to a waste liquid collection device for intervertebral foraminal endoscopic surgery. Background Art

[0002] Waste liquid collection bags are disposable medical supplies used by hospital clinical departments to collect and store waste liquids during transforaminal endoscopic lumbar disc surgery and similar surgeries. They are mainly used to collect various waste liquids generated during surgery, such as saline flushing fluid, blood, etc., to prevent waste liquids from overflowing and polluting the environment. Waste liquid collection bags are usually bag-type structures with a liquid outlet and a liquid inlet, which are convenient for connection with extracorporeal tubing and drainage catheters to form a closed drainage system. Some designs also include a flexible support body to prop open the liquid inlet to ensure smooth flow of waste liquid. Waste liquid collection bags are widely used in hospital clinical departments. During transforaminal endoscopic lumbar disc surgery, waste liquid collection bags serve as an important auxiliary tool during surgery. They can effectively collect and store waste liquids to ensure the safety and smooth progress of the operation.

[0003] As a minimally invasive procedure, transforaminal endoscopic lumbar discectomy (PELV) offers advantages such as minimal trauma, minimal bleeding, and rapid recovery. It is widely used to treat spinal conditions such as lumbar disc herniation. During surgery, to maintain a clear surgical field of view, the surgical area must be continuously flushed with saline solution, which generates a large amount of waste fluid. This waste, including saline, blood, and tissue fluid, can negatively impact the surgical environment, medical staff, and patients if not collected and processed promptly and effectively.

[0004] With the increasing popularity of transforaminal endoscopic lumbar discectomy (PELS) and the continuous advancement of technology, the use of waste collection bags in surgery is becoming increasingly widespread. Medical institutions are gradually recognizing the importance of waste collection bags and incorporating them into standard surgical preparation procedures. Furthermore, a wide variety of waste collection bags in different specifications and materials are now available on the market for medical institutions to choose from.

[0005] During perforaminal endoscopic lumbar discectomy, since the medium between the perforaminal endoscopic discectomy and the tissue is saline, in order to clean bleeding and enhance the field of vision, it is necessary to continuously flush with saline, which can easily cause the saline to flow everywhere and cause contamination. The current treatment method is to use a water collection bag made of waterproof film and lay it on the patient so that the saline can only flow to one side and be collected together. However, some of the saline will inevitably overflow to the surroundings, affecting the smooth progress of the operation. Utility Model Content

A plurality of baffles 104 are provided in the water collecting portion 101 . The baffles 104 form a channel toward the flow guiding portion 102 . A filter element 106 is provided in the flow guiding portion 102 .

[0050] The waste liquid collection device of this embodiment is used for transforaminal endoscopic lumbar discectomy. The water collection portion 101 is located at the patient's surgical site and, in conjunction with the barrier portion 104, directs waste liquid generated after the surgical area is flushed with saline solution into the drainage portion 102. This blocks splashed waste liquid, allowing it to enter the drainage portion 102 through the channel to prevent cross-infection. The filter element 106 filters the waste liquid before collecting it in the waste liquid collection bag 2. Furthermore, because the water collection bag 1 and the waste liquid collection bag 2 are connected by a quick-connect connector 4, they can be separated and the waste liquid collection bag 2 can be sealed, allowing for quick replacement of the waste liquid collection bag 2 while preventing leakage of waste liquid and the spread of pathogens.

[0051] The water collection bag 1 of this embodiment includes a waterproof cloth 103 and a support member. The support member is multiple and connected to form a square support frame. The waterproof cloth 103 is sleeved on the support frame to form a water collection portion 101.
