TECHNICAL FIELD
[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a multifunctional probe convenient for fistula exploration and treatment. BACKGROUND
[0002] At present, the commonly used probe in fistula treatment is mainly a solid metal probe, which is relatively simple in design and is mainly used for exploring the general trend of the fistula and determining its position. During the operation process, the doctor will slowly insert the probe into the fistula from the external fistula opening along the fistula path until the internal fistula opening is found. However, when the fistula is curved or branched, the probe may be difficult to directly reach the internal opening. In this case, the doctor usually injects a color developing agent (such as methylene blue) from the external opening to more accurately locate the position of the internal opening. Once the position of the internal opening is determined, the doctor will withdraw the probe and use a curette to remove the necrotic tissue in the fistula. However, due to the relatively large size of the curette, the fistula may be expanded when the curette is inserted into the fistula, and even the muscle tissue around the fistula may be damaged, sometimes the false channel or false internal opening may be induced, thereby further damaging the surrounding tissue. In order to ensure the cleaning of the inside of the fistula, the doctor will use physiological saline or hydrogen peroxide to repeatedly flush after cleaning. In addition, the fistula threading operation is commonly used to treat anal fistula and other diseases. During the operation, a sterile probe is inserted into the fistula opening, and the fistula path is detected along the fistula path. After confirming that the fistula is unobstructed, the guide wire is inserted through the probe, the probe is pulled out, and the guide wire is retained in the fistula. The guide wire is introduced into the threading material along the guide wire, the threading material is passed through the fistula along the guide wire, the guide wire is pulled out, and the threading material is retained in the fistula. In the above process, whether it is to explore the internal opening, clean the fistula, or thread, it needs to be carried out in layers, which makes the operation process relatively complicated and inevitably causes damage to the tissue in the fistula.
[0003] Therefore, it is particularly important to develop a multifunctional probe for fistula exploration, cleaning and treatment. UTILITY MODEL CONTENTS
