Description

Technical Field

[0001] This utility model relates to the field of surgical scalpel handle kits, and in particular to an auxiliary tooling for installing scalpel handle kits. Background Technology

[0002] An ultrasonic scalpel is a medical device that uses high-frequency ultrasonic energy for surgery. It works by converting electrical energy into high-frequency ultrasonic vibrations, which are transmitted through specific blades to achieve precise tissue dissection and coagulation. There are two main types: suction and cutting, each with different working principles and clinical applications. The use of an ultrasonic scalpel can reduce damage to surrounding tissues, reduce intraoperative bleeding, improve surgical field clarity, lower surgical risks and infection rates, accelerate postoperative recovery, and is easy to operate with a wide range of applications. Ultrasonic scalpels are widely used in multiple fields, including cataract emulsification, hepatobiliary tumor aspiration, liposuction, bone cutting, hemostasis, and debridement. Soft tissue ultrasonic scalpels are suitable for multiple departments, such as gynecology, urology, and thoracic surgery, covering dozens of surgical procedures. Ultrasonic bone scalpels are mainly used in dentistry and oral and maxillofacial surgery, and are gradually expanding into areas such as spinal surgery.
