An intraluminal ultrasound device configured to be inserted within an inner wall defining a lumen of a patient can include a housing extending from a proximal section to a distal section along a central axis. The housing can include a transducer configured to capture ultrasound images and a mounting component configured to receive the transducer. The intraluminal ultrasound device can also include a force generation system operable to maintain contact between the inner wall and the transducer, in turn causing a reduction in an air gap between the lumen and the transducer.

This invention relates to the field of medical aesthetics and skin repair devices. The invention discloses a needle tip temperature control and cooling device and a radiofrequency microneedle device equipped with the same. The needle tip temperature control and cooling device includes a housing with a receiving cavity and an opening facing the treatment area. A negative pressure chamber is located at the opening facing the receiving cavity, and the negative pressure chamber also has a negative pressure through-hole for communication with a negative pressure output device. It also includes an adaptive cold conduction component disposed at the opening. The adaptive cold conduction component includes independent first and second cold conduction components. The second cold conduction components are U-shaped, and several second cold conduction components are arranged in a three-sided arrangement away from the first cold conduction component. When the first and second cold conduction components have an axial displacement difference, a fitting gap is formed. This fitting gap is configured to form an airflow channel under negative pressure, using airflow shear force to remove condensate from the surfaces of the first and second cold conduction components.

The application provides a circuit board and a manufacturing method thereof. A medium layer source, i.e., a resin source, is divided into multiple parts, i.e., a top medium layer above a buried device and an intermediate medium layer between core boards. In a pressing process, the top medium layer above the buried device fills a gap between an upper frame (a second core board) and the buried device, and the intermediate medium layer between the core boards quickly fills a gap between a lower frame (a first core board) and the buried device. The vertical distance of resin flow is greatly reduced, the resin flowability is greatly improved, the problem of insufficient filling caused by insufficient resin flowability or mismatched curing speed can be effectively avoided, the problem of insufficient glue filling capacity of a traditional single-frame design when processing a large-thickness component is solved, and the reliability and stability of the buried device are improved.
