Surgical ultrasonic tool with disposable tip

Abstract

The invention provides a surgical ultrasonic tool with a disposable tip, comprising: an ultrasound-driven handle; a tip, wherein the tail of the tip is provided with a connection thread structure forconnection with the ultrasound-driven handle; a tip sheath sleeving the tip through a fixing connection structure; an anti-recycle component arranged at the front end of the tip and the tip sheath tocover the front end of the tip after use. The tip sheath, the tip and a manual switch are assembled into a disposable component, so that using is convenient and quick and may be performed just by connecting the tip and the ultrasound-driven handle; the anti-recycle component is provided to cover the front end of the tip and the tip sheath after use, reuse can be avoided, and the tip can be quicklycovered to avoid injury caused by the tip.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical ultrasonic knife with a disposable knife head. Background technique [0002] At present, in surgical operations, ultrasonic scalpels are more and more widely used. At present, in surgical operations, the application of ultrasonic surgical instruments is becoming more and more extensive. Then, existing ultrasonic surgical instruments have some defects and deficiencies in their structures. [0003] Among them, in many surgical operations (such as orthopedic surgery, neurosurgery), the cutter head of the ultrasonic scalpel needs to directly enter the patient's body for surgical operations. The existing ultrasonic surgical knives are often reused. High-standard disinfection consumes extra manpower and physics, and increases the operating cost of the hospital; secondly, reusable knives may cause surgical infection or infectious diseases, posing safety hazards....

Problems solved by technology

[0003] Among them, in many surgical operations (such as orthopedic surgery, neurosurgery), the cutter head of the ultrasonic scalpel needs to directly enter the patient's body for surgical operations. The existing ultrasonic surgical knives are often reused. High-standard disinfection consumes extra manpower and physics, and increases the operating cost of the hospital; secondly, reusable knives may cause surgical infection or infectious diseases, posing safety hazards

[0004] In addition, after the existing cutter head is connected to the ultrasonic drive handle, the cutter head part is equipped with a cutter head sheath, which is used to protect the non-active part of the cutter head in the waveguide section, and the sheath is also fixed on the handle at the same time Yes, because doctors are not familiar with the installation and use of instruments, or are negligent, they may mistake the installation sequence, install the knife head sheath first, and forget to install the knife head
