Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for preventing splashing of waste fluid and collecting specimens during transurethral prostate surgery. Background Technology

[0002] Transurethral resection of the prostate (TURP) is a widely used surgical procedure for treating lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH). Considered the gold standard for treating these symptoms, the procedure involves continuous flushing with saline solution. However, TURP typically consumes a large volume of flushing fluid, ranging from 50,000 to 75,000 ml. This significant consumption generates substantial amounts of waste gas and fluid, significantly impacting the operating room environment. Timely and effective recovery of the waste fluid is crucial for the successful execution of the procedure. However, this task presents a considerable challenge for operating room staff. Due to the high-energy, high-power cutting equipment used in the procedure, harmful liquids in open containers may evaporate before the waste fluid container is fully filled, producing large amounts of irritating gases. These gases have a stronger odor than the fumes produced by electrocautery or ultrasonic scalpels, posing a threat to the health of medical personnel and severely polluting the operating room environment.

[0003] During transurethral resection of the prostate (TURP), electrosurgical devices (ESUs) affect human tissue through thermal decomposition and ablation, causing mucosal rupture. During this process, proteins, fats, and bodily fluids undergo incomplete combustion in carbon dioxide (CO2), producing gaseous byproducts known as surgical fumes. Surgical fumes generated when using electrosurgical devices, lasers, and ultrasonic scalpels contain harmful components such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), particulate matter, and live microorganisms, posing physical, chemical, and biological hazards to healthcare workers. Inhalation of these particles can lead to inflammation, lung damage, and exposure to mutagens and carcinogens, and may even transmit human papillomavirus (HPV) and other pathogens. Surgical fumes pose potential health hazards, including various respiratory symptoms, systemic damage, pathogen transmission, and tumor metastasis, and are closely related to occupational exposure for surgical personnel. During TURP, harmful fluids in open containers (such as saline or other irrigation fluids) may release volatile organic compounds (VOCs) and bacteria. Volatile chemicals can cause respiratory irritation, headaches, and allergic reactions, increasing occupational health risks for healthcare workers. Furthermore, if the liquid contains pathogens, it can lead to the spread of infection. These risks need to be mitigated through appropriate protective measures. Maintaining dry and clean floors in the operating room environment is crucial for reducing the incidence of electric shock accidents. This not only relates to the safety of the surgical procedure but also affects the hygiene of the postoperative recovery environment. Dry floors effectively prevent slips caused by liquid splashes or spills and reduce the risk of electric shock from slippery environments. In addition, wastewater treatment increases economic costs. Wastewater generated during surgery requires professional treatment, increasing the operating costs of medical institutions. If doctors and healthcare workers need to change clothes due to wet wastewater during surgery, it may result in additional washing and changing costs. Changing clothes and cleaning the operating room can also delay surgery time, affecting surgical scheduling and efficiency, and increasing human and material costs. Therefore, how to effectively treat surgical wastewater, reduce its impact on the environment and healthcare workers, and control costs are issues that hospital administrators need to seriously consider.

[0004] To address this issue, on July 5, 2017, the Hospital Infection Control Professional Standards Committee published five infection control-related standards on the National Health Standards website, including the "Guideline for Hospital Infection Control in Operating Rooms." This guideline clearly states that surgical waste fluids contain large amounts of blood and bodily fluids, which can easily contaminate various items in the operating room, becoming a significant source of pollution. Therefore, as one of the most vulnerable locations for hospital-acquired infections, infection control in the operating room is of paramount importance.

[0005] Currently, my country generally does not pay enough attention to the disposal of medical waste, and the vast majority of hospitals still use the traditional method of collecting waste fluids in water buckets. Therefore, in order to ensure the smooth progress of surgery, the recycling and discharge of flushing waste fluids is particularly important. In actual surgical procedures, it is not uncommon for surgery to be paused and replaced due to the waste fluid collection buckets being full. This not only delays the surgical process but may also have adverse effects on the patient's health.

[0006] Patent application CN201420433941.X discloses a ureteroscopic drainage bag. This design aims to improve efficiency and safety during the procedure while reducing the risk of contamination in the surgical environment. The drainage bag includes a main drainage bag with its lower outlet connected to the inlet of a collection bag, ensuring effective collection of fluids generated during the procedure. An operating hole is designed at the top of the drainage bag for the entry and exit of surgical instruments, and a conical operating sleeve embedded within the drainage bag is connected to this operating hole. The tip of the conical operating sleeve has an opening, allowing surgical instruments to pass smoothly while maintaining the airtightness of the drainage bag. However, although the above-mentioned drainage bag device can effectively collect waste fluid through the waste fluid collection bag, avoiding medical exposure, its collection device is inconvenient for recycling, the emptying process is not convenient enough, and it cannot meet the needs of long-term use. For surgeries requiring specimen collection, the use of this design is somewhat limited.

[0007] Therefore, the present invention provides a device for preventing splashing of waste fluid and collecting specimens during transurethral prostate surgery. Summary of the Invention
