Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cutter heads, in particular to a rotating device for an ultrasonic cutter head. Background Art

[0002] The ultrasonic scalpel uses the conversion of ultrasonic energy and transmits it into biological tissues. The thermal effect generated by its mechanical vibration breaks the hydrogen bonds of tissue proteins and denatures and coagulates the proteins. Therefore, the mechanical energy and thermal energy generated can be used to coagulate, stop bleeding and cut tissues. It has the characteristics of low smoke production and excellent hemostatic effect, and is widely used in surgical operations.

[0003] In the existing technology, when using an ultrasonic scalpel, it is usually necessary to rotate the angle multiple times to better adapt to the surgical scene. However, the rotation unit of the existing ultrasonic scalpel head does not have a locking mechanism. The rotation unit is prone to accidental rotation due to operational errors of medical staff, thereby affecting the progress of the operation. Therefore, we have introduced a rotation device for the ultrasonic scalpel head. Utility Model Content

[0004] The purpose of the present utility model is to provide a rotation device for an ultrasonic blade head, which can not only quickly lock the ultrasonic blade head during surgery to prevent accidental rotation from causing surgical failure, but also quickly unlock the ultrasonic blade head when it is necessary to rotate it, with a high degree of convenience, so as to solve the problems raised in the above-mentioned background technology.

When the ultrasonic blade head needs to be rotated, the medical staff uses their free hand to grasp the locking wheel and push the locking wheel to the side close to the ultrasonic blade head, the locking wheel slides on the sleeve, and the two sliding rods slide into the inside of the sliding groove. At the same time, one end of the sliding rod squeezes the spring, and the locking wheel moves while driving the locking rod to move outside the locking groove. At this time, the lock is released, and the locking wheel is rotated. The locking wheel drives the rotating wheel to rotate through the sliding groove and the sliding rod, and the rotating wheel drives the ultrasonic blade head to rotate through the sleeve and the ultrasonic blade rod. After rotating to the required angle, the locking wheel is released, and the spring pushes the locking wheel and drives the locking rod to engage in the corresponding locking groove.
