Description

Technical Field

[0001] The utility model belongs to the technical field of amplitude transformers, and in particular relates to an amplitude transformer structure of an ultrasonic surgical knife. Background Art

[0002] The ultrasonic horn is an important component in the ultrasonic vibration system. Its main function is to amplify the particle displacement or velocity of mechanical vibration and concentrate the ultrasonic energy on a smaller area, i.e., focus the energy.

[0003] The working principle of the ultrasonic scalpel horn is to convert ultrasonic electrical energy into mechanical energy by using the electrostrictive effect or magnetostrictive effect. Through the amplification coupling of the horn, the horn is driven to work, and the energy is radiated to the local tissue of the human body for surgical treatment. The ultrasonic scalpel vibration system using the electrostrictive effect consists of a piezoelectric transducer, an ultrasonic scalpel horn and a scalpel head. The piezoelectric sheet is fixed by a pre-tightening screw to convert the electrical energy of the power supply into vibration mechanical energy. The horn amplifies the displacement or speed of mechanical vibration by concentrating the ultrasonic energy in a small area. Its shape has different types such as exponential, step and catenary shapes, such as linear and compound. The radiated acoustic energy of the ultrasonic scalpel horn cuts or emulsifies human tissue and sucks it out of the body by negative pressure.

[0004] The existing ultrasonic scalpel amplitude transformer can amplify the vibration amplitude when in use. Due to the high-frequency vibration of the amplitude transformer, both medical staff and patients will feel uncomfortable when they come into contact with the amplitude transformer, thus affecting the comfort of the ultrasonic scalpel.

A docking groove is provided at the end of the amplitude change rod body, and fixing bolts are inserted into the fixing hole and the docking groove.

[0008] In order to conveniently limit the movement direction of the silicone sleeve, as a preferred structure of an ultrasonic surgical knife amplitude transformer of the utility model, the silicone sleeve is slidably connected with the guide slide groove and the guide slide rail.

[0009] In order to facilitate fixing the position of the silicone sleeve, as a preferred structure of an ultrasonic surgical knife amplitude transformer of the utility model, two groups of fixing holes, fixing bolts and docking grooves are provided, and the fixing bolts and the docking grooves are threadedly connected.

[0010] In order to facilitate fixing the position of the scalpel joint, as a preferred structure of an ultrasonic scalpel amplitude transformer of the utility model, a positioning hole is opened on the end surface of the scalpel joint, and a positioning column is connected to the end of the amplitude transformer body near the positioning hole.

[0011] In order to facilitate the installation of the scalpel joint, as a preferred structure of an ultrasonic scalpel amplitude transformer of the utility model, the surface of the scalpel joint is sleeved with a fixing sleeve, and the surface of the end of the amplitude transformer body is connected with a thread.

[0012] As a preferred structure of an ultrasonic surgical knife amplitude transformer of the utility model, the positioning holes and positioning posts are provided with two groups, the surgical knife joint is slidably connected with the positioning posts through the positioning holes, and the fixing sleeve and the thread are threadedly connected.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the silicone sleeve is sleeved on the surface of the amplitude transformer body and the guide slide groove is aligned with the guide slide rail. Then the silicone sleeve drives the guide slide groove to slide on the surface of the guide slide rail.

Then the fixing bolt is rotated to be threadedly connected with the docking groove. In this way, the position of the silicone sleeve can be fixed, so that the silicone sleeve can be used to wrap the amplitude transformer body when it vibrates at a high frequency, thereby preventing medical staff or patients from directly contacting the ultrasonic scalpel and causing discomfort.

[0015] 2. In the utility model, when the scalpel joint is installed, the scalpel joint first drives the positioning hole to slide on the surface of the positioning column, and then the fixed sleeve is sleeved on the surface of the scalpel joint and moves in the direction close to the amplitude transformer body.
