Problems solved by technology

For soft tissues such as liver and brain, the cutting effect of traditional scalpels is poor, and multiple cuts are required to achieve thorough cutting
Therefore, the ultrasonic cutting knife came into being. However, the general ultrasonic cutting knife has a relatively fixed shape and is not easy to bend. It is difficult to cut small parts, so it is more inconvenient to use.

Embodiment Construction

[0017] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention.

[0018] The invention relates to an ultrasonic scalpel. For example, the ultrasonic scalpel includes a cutting head, a curved portion, a rigid knife rod, an ultrasonic amplifier, a piezoelectric transducer and a pressing handle. For example, the cutter head is connected to the rigid cutter rod through the bending part, the ultrasonic amplifier is connected to the rigid guide rod, and the ultrasonic amplifier, the piezoelectric transducer and the pressing handle are sequentially connect. For example, a pressing wrench is rotatably provided on the pressing handle, and the pressing wrench is connect...

Abstract

The invention relates to an ultrasonic scalpel. The ultrasonic scalpel comprises a scalpel head, a bent part, a rigid scalpel rod, an ultrasonic amplifier, a piezoelectric transducer and a pressing handle. The scalpel head is connected with the rigid scalpel rod through the bent part; the ultrasonic amplifier is connected to the rigid scalpel rod; the ultrasonic amplifier, the piezoelectric transducer and the pressing handle are connected in sequence, a pressing wrench is rotationally arranged on the pressing handle, and the pressing wrench is connected with the scalpel head through a transmission steel wire. The ultrasonic scalpel is convenient to use.

Description

technical field [0001] The invention relates to an ultrasonic scalpel. Background technique [0002] A traditional scalpel is generally composed of a handle and a blade. During the operation, the doctor uses the wind-powered blade to cut tissue cells. For soft tissues such as liver and brain, the cutting effect of traditional scalpels is poor, and multiple cuts are required to achieve thorough cutting. Therefore, an ultrasonic cutting knife emerges as the times require. However, the general ultrasonic cutting knife has a relatively fixed shape and is not easy to bend. It is difficult to cut a narrow part, so it is inconvenient to use. Contents of the invention [0003] Based on this, it is necessary to provide an ultrasonic scalpel that is more convenient to use. [0004] An ultrasonic scalpel, comprising a cutter head, a curved part, a rigid knife rod, an ultrasonic amplifier, a piezoelectric transducer and a pressing handle, the cutter head is connected to the rigid kn...
