Description

Ultrasonic closing clamp and ultrasonic knife system

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an ultrasonic closing clamp and an ultrasonic knife system.

Background

The ultrasonic soft tissue cutting hemostasis system (hereinafter referred to as ultrasonic knife system) is characterized in that ultrasonic frequency current generated in a main machine of the ultrasonic knife system is conducted to a transduction handle, the transduction handle converts electric energy into front-back vibration mechanical energy, the tail end of a knife head vibrates at a certain frequency (for example, 55.5 kHz) through transmission and amplification of the knife head, heat generated by friction causes vaporization of water in tissue cells contacted with the knife head, protein hydrogen bonds are broken, cell disintegration and recombination are carried out, and the tissue is cut after solidification; when cutting blood vessels, the cutter head is contacted with tissue protein, heat is generated through mechanical vibration, so that the collagen structure in the tissue is damaged, the protein is solidified, the blood vessels are further sealed, and the hemostatic purpose is achieved. The current device is suitable for soft tissue cutting which needs to control bleeding and minimal thermal injury, and can be used for closing blood vessels with diameters not exceeding 5 mm.

Ultrasonic soft tissue cutting hemostatic systems are generally used clinically only for the closure and cutting of smaller diameter vessels (e.g., 5mm and beyond), because of the mechanical, thermal, and cavitation effects of ultrasound, and therefore, when the vessel is closed, the tissue melts and then recondenses, allowing the tissue at the closure to fuse together, forming a sealed cavity. However, due to the special structure and the special size of the front end of the amplitude transformer in the ultrasonic knife acoustic system, the size of a section capable of being sealed is smaller, and the safety of sealing blood vessels is insufficient.

In the treatment of large vessels where ultrasonic blades are not stable, bipolar blades, which use high frequency RF energy (e.g., 300 khz,300v ac signals), which are used to treat vascular tissue, vascular clamps, vascular staplers, etc., are routinely used, using the thermal effects of electrical current, which can easily cause high temperatures (e.g., 300-400 c) to cause thermal damage to the tissue and charring eschar. The vascular anastomat adopts a staple method, and the blood vessel is directly sutured through 2-3 rows of staples and then cut by using a built-in blade. The vascular clip is generally mechanical and consists of a gun-type clip applier and a closure clip, wherein the clip applier is generally reusable, and the closure clip is disposable and is placed in the human body after clamping the target tissue. However, after the tissue or the blood vessel is clamped by the closed clamp, the risk of falling exists, and the tissue is clamped by the vascular clamp in a mechanical mode generally, if falling occurs, the blood vessel bleeding easily occurs in the section, and serious medical accidents such as injury or death of patients are caused.
