Description

Technical Field

[0001] This utility model relates to an auxiliary device, and more particularly to a preoperative auxiliary device for microwave ablation surgery of pulmonary nodules, belonging to the field of medical auxiliary device technology. Background Technology

[0002] Lung nodule ablation is a minimally invasive surgical procedure targeting lung nodules. This procedure primarily utilizes techniques such as radiofrequency, microwave, or cryotherapy to apply high or low temperatures to the nodule tissue, causing it to coagulate or freeze, thereby removing the lesion. This surgical method is suitable for various types of lung nodules, such as infectious tuberculomas and early-stage lung cancer, and is particularly suitable for cases where the nodule diameter is less than 3 cm, the location is inconvenient for open-chest surgery, or the patient is unsuitable for traditional surgery. Before the microwave ablation procedure for lung nodules, the surgical site generally needs to be disinfected. The doctor uses sterile cotton placed on a sterilization rack to disinfect the patient's affected area.

[0003] When using sterile cotton swabs on a sterilization rack, medical staff usually need to use sterilized tweezers to pick up the strictly sterilized cotton swabs and then frequently dip them into a container of disinfectant to apply an appropriate amount of disinfectant to the patient's affected area. However, the frequent dipping of the cotton swabs into a particular spot can contaminate the disinfectant solution. Each time the cotton swabs are dipped, the tweezers or cotton swabs may carry trace amounts of bacteria or contaminants. These microorganisms accumulate in the disinfectant solution, gradually reducing its bactericidal effect and posing a serious threat to the patient's safety. Utility Model Content

The base 22 and the wheels 23 allow the preoperative auxiliary device to be moved flexibly, making it more convenient to use. The fixed connection between the base 22 and the support 8 facilitates the support and fixation of the support 8.

[0032] In use, the preoperative auxiliary device is first moved to the operating room using the wheels 23 as needed. During use, sterilized forceps are placed in the placement box 4 and fixed in place by the magnet base 10. Then, when disinfecting the patient's affected area, the solenoid valve at the discharge pipe 7 is controlled to add an appropriate amount of disinfectant to the dipping container 5. The doctor then takes the forceps, holds a sterilized cotton swab, dips it in the disinfectant from the dipping container 5, and wipes the patient's affected area. After wiping... The electric motor 19 drives the disc 3 to rotate. Combined with the bullseye wheel 20 and the guide groove, the disc 3 can be limited and guided during rotation, thus rotating the disc 3 by 90 degrees. This places the new dip container 5 below the discharge pipe 7. The above steps are repeated to inject the disinfectant into the inner wall of the dip container 5 in a measured amount. The patient's affected area can then be disinfected by using tweezers to hold the disinfectant cotton. This ensures that the disinfectant is not contaminated during each disinfection process, effectively maintaining the bactericidal efficacy of the disinfectant and strictly protecting the patient's life safety.

[0033] During the surgery, the height of the dipping container 5 can be adjusted as needed. The forward and reverse motor 904 drives the lead screw 901 to rotate, which, combined with the lead screw nut and guide rod 903, moves the moving block 902 along the surface of the lead screw 901. This adjusts the height of the support plate 1 and the dipping container 5, greatly improving the ease of operation for the doctor. After the surgery, the placement box 4 and the dipping container 5 are disassembled, cleaned, and disinfected using the magnetic strip 18. The pull rod 1304 separates the limiting rod 1301 from the limiting hole, allowing the slider 11 and the container body 6 to be disassembled and removed. The inside of the container body 6 can then be disinfected.
