Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ultrasonic surgical blade head, an ultrasonic surgical blade and an ultrasonic surgical blade system. Background Art

[0002] In clinical practice, ultrasonic scalpels have very good effects, for example: neat incisions, fast hemostasis, small range of thermal damage, less smoke generated, etc., and have now become an important tool for clinical surgery. With the continuous development of science and technology, the requirements for ultrasonic scalpels are getting higher and higher. These problems are mainly manifested in that the ultrasonic scalpel is easily affected by external interference and load during operation, and it is easy to convert its vibration mode from simple longitudinal vibration to other vibration modes, thereby affecting the working efficiency and cutting ability of the ultrasonic scalpel. In addition, the existing ultrasonic back incision is not easy to control the depth and is prone to slipping; the large lateral vibration causes the blade to break easily, and the water mist is relatively large, affecting the surgical vision; and the blade structure is arc-shaped, which has a certain degree of processing difficulty, so the side of the blade is currently processed directly, and the water mist caused by the cavitation effect on the side is horizontally divergent; this causes certain difficulties for clinicians to precisely control the scalpel, thereby affecting the surgical effect and even endangering the patient's personal safety. Traditional ultrasonic scalpels are gradually unable to meet these needs. Summary of the invention

[0006] An ultrasonic surgical blade comprises a balancing structure, wherein the balancing structure comprises a first balancing surface, and one end of the first balancing surface extends along the top direction of the blade.

[0007] Preferably, the balance structure further includes a second balance surface, and the first balance surface is connected to the second balance surface; one end of the second balance surface extends along the direction of the bottom of the tool head, and the second balance surface is arc-shaped.

[0008] An ultrasonic surgical tool head includes a first cutting structure and a balance structure.

The first side cutting surface and the second side cutting surface are both designed in an inner concave shape, enabling the water mist to be focused near the side of the scalpel head during the divergence process. Through focusing, most of the divergence energy of the water mist can be mutually offset, thereby effectively reducing the amount of water mist and improving the visual clarity during the operation. The shape of the scalpel head is not symmetrical, and the center of gravity deviates from the axis, resulting in transverse vibration (yaw) in the direction of the center of gravity deviation during vibration. The greater the transverse vibration, the more likely it is that the stress on the scalpel head is greater, thus leading to fatigue fracture of the scalpel head. The balance structure can reduce the transverse vibration, effectively reducing the transverse vibration of the scalpel head top caused by the eccentricity of the scalpel head top, thereby reducing the stress on the scalpel head during vibration, achieving the reduction of the probability of the scalpel head breaking and increasing the service life of the scalpel head.
