Description

Intraoperative sound guide pad for medicine injection treatment under guidance of nasolabial sulcus ultrasound

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an intraoperative sound conduction pad for medicine injection treatment under the ultrasonic guidance of nasolabial sulcus.

Background

With the development of medical cosmetology, the injection of medicaments at the nasolabial sulcus part is increased day by day, but the injection of medicaments such as hyaluronic acid has certain risks, and a serious complication is that the medicaments are carelessly injected into blood vessels to cause blood vessel embolism. Other nasal tumors, such as hemangiomas and vascular malformations, also require drug sclerotherapy at the site of the lesion, so real-time visualization of the blood vessels during injection is important.

Real-time guidance of ultrasound during surgery can ensure that the drug injection can safely and effectively reach the target site. But it is difficult to adapt to the morphology of the nose using current intraoperative ultrasound coupling materials. Most of sound conducting materials used for ultrasonic guidance in the prior art are iodophor or lidocaine gel which is used as a coupling agent, the iodophor is used as a liquid component, the sufficient sound conducting thickness is difficult to generate, the detailed observation effect for observing superficial tissues is poor, although the lidocaine gel can be coated with a certain thickness, a stable sound conducting layer cannot be formed, and the operation is inconvenient in the art. And the sound guide materials used in the past, such as iodophor, lidocaine gel and the like, cannot adapt to the shape of the nose, so that the observation of a tumor in multiple angles and the selection of a proper needle insertion path are inconvenient in the operation, or the observation of blood vessels at the nasal wing is unstable during the cosmetic injection, and the medicine, such as hyaluronic acid and the like, cannot be ensured to be injected to the nasolabial sulcus part uniformly and safely and cannot enter the adjacent facial artery branch. In addition, the couplant and the iodophor are difficult to be tightly attached to the nasolabial sulcus while bubbles are not generated in the smearing process, and if air components exist between a human body and the probe, the quality of ultrasonic imaging is reduced. The discomfort of the sound guide material can cause the inconvenience and inaccuracy of the operation during the ultrasonic guidance in the operation, and the accurate information can not be provided for the clinic, thereby influencing the accurate injection of the medicine.
