Provided is a bell-mouth structure (20). The bell-mouth structure (20) comprises: a cylindrical part (21) constructed so as to surround a fan 12; a base part (30) extending outward from one end of the cylindrical part; and a plurality of reinforcement members (33 / 35) protruding downward from a surface forming the base part (30). The plurality of reinforcement members (33 / 35) are provided at a plurality of positions around the cylindrical part (21) in directions generally symmetric with respect to the center (O) of the cylindrical part (20) in a plan view of the base part (30). The plurality of reinforcement members (33 / 35) each have a shape that is curved with respect to the center of the cylindrical part (21).

This invention discloses a steerable radiofrequency ablation and plasma ablation surgical forceps for laparoscopic surgery, relating to the field of medical device technology. It includes a proximal component for manipulation, a slender main body component that enters the body cavity, and a distal working component. The main body component includes a hollow sleeve, a pull rod slidably connected within the sleeve, and a gripping portion fixed to the outside of the sleeve. The segment of the sleeve near the gripping portion has an upper notch structure, at which a drive component for steering the working component is provided. By integrating a bipolar radiofrequency electrode and a localized liquid spray system on the same jaw structure, structural integration of both radiofrequency ablation and plasma ablation energy action modes is achieved. A unique sliding key joint structure decouples the axial sliding and circumferential rotation of the pull rod, allowing independent control of jaw opening and closing and working component steering without interference.

This application belongs to the field of medical device technology, specifically relating to a disposable sampler. The sampler includes a handheld part, an extension part, and a sampling part, which are connected sequentially from proximal to distal. The sampling part has an open structure with a closed bottom and an open top, and the bottom end of the sampling part is connected to the distal top end of the extension part. Compared to traditional cotton swab-style cylindrical sampling heads, this open structure of the sampling part increases the sampling contact area, allows the opening edge to better fit the nasal cavity wall for rapid accumulation of secretions, and improves sampling efficiency. Furthermore, the connection between the bottom end and the distal top end of the extension part creates a suspended design, effectively reducing the space occupied by the sampling end, facilitating flexible insertion into the narrow nasal cavity and adjustment of the angle, reducing mucosal irritation, improving patient experience, and avoiding sampling omissions and insufficient sampling volume, ensuring sampling reliability and the accuracy of subsequent test results.
