[0002] An ultrasonic scalpel is a high-frequency electrosurgical device, which is mainly used for operations such as cutting biological tissues and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and fast recovery after surgery. It acts on human tissues to cut and coagulate, and does not cause side effects such as tissue drying and burns. When the blade is working, no current passes through the human body, and it is widely used in operating rooms. The main components of an ultrasonic scalpel include: a host, a transducer, and an ultrasonic scalpel, wherein the host is used to convert electrical signals into high-frequency oscillation signals, and then convert the signals into high-frequency mechanical signals, i.e., high-frequency mechanical vibrations, through the transducer. However, the blade head of the prior art is usually in the shape of a straight sheet, and when it is necessary to cut out tissue of a specific shape, its cutting efficiency is poor.

[0024] Example 1
[0025] Reference Figure 1 and Figure 2The first embodiment of the present application provides a frosted ultrasonic sheet cutting blade head, comprising: a horn 10 and a blade body 40. The horn 10 is used to connect with the ultrasonic transducer; one end of the blade body 40 is connected to the horn 10, and the other end of the blade body 40 is a free end. The blade body 40 includes a first working section 41 and a second working section 42. The plane where the first working section 41 is located is parallel to the axis of the horn 10. The free end of the blade body 40 is bent to one side to form the second working section 42. An angle is formed between the plane where the first working section 41 is located and the plane where the second working section 42 is located.
[0026] In this embodiment, one end of the horn 10 is connected to the blade 40, and the other end of the horn 10 is used to connect to the ultrasonic transducer, and the ultrasonic transducer is connected to the ultrasonic generator. The working principle of the ultrasonic scalpel is to use the ultrasonic generator to convert the electrical signal into a high-frequency oscillation signal, and then convert the high-frequency oscillation signal into a high-frequency mechanical signal, that is, high-frequency mechanical vibration, through the ultrasonic transducer. The main function of the horn 10 is to concentrate the ultrasonic energy on a smaller area, thereby amplifying the displacement or speed of the mechanical vibration. This is very important for meeting the amplitude required for cutting biological soft tissue during surgery. Specifically, when cutting biological soft tissue at an operating frequency of 50-60KHZ, the amplitude of the ultrasonic scalpel head must reach tens to hundreds of microns, and the setting of the horn 10 can ensure that the amplitude of the output end of the blade 40 meets this requirement. The blade 40 is a sheet with a consistent thickness, one end of the blade 40 is connected to the horn 10, the other end of the blade 40 is a free end, and the part of the blade 40 exposed from the horn 10 is the working part of the blade 40. The first working section 41 and the second working section 42 are distinguished only for the convenience of description. The first working section 41 can be formed by bending the second working section 42 to one side. The free end of the first working section 41 is laterally offset from the second working section 42 by a certain distance, so that when cutting the tissue structure, the free end of the first working section 41 can be laterally extended to a position that the second working section 42 cannot reach. Especially when delicate operations are required or when bypassing other tissues for surgery, the first working section 41 and the second working section 42 of the knife body 40 can significantly improve the flexibility and accuracy of the operation.
[0027] Example 2
[0028] As an optional implementation, refer to Figure 1 The present embodiment provides a specific structure of a variable amplitude rod 10, including: one end of the variable amplitude rod 10 for connecting with the blade body 40 has a clamping portion 20, the clamping portion 20 is covered on a portion of the first working section 41, the clamping portion 20 has a first clamping surface 21 and a second clamping surface 22 opposite to each other, and the distance between the first clamping surface 21 and the second clamping surface 22 gradually decreases in the direction away from the variable amplitude rod 10.
[0029] In this embodiment, by adding a clamping portion 20 at the end of the horn 10, the contact area between the horn 10 and the blade 40 is increased, and the clamping stability of the blade 40 is improved. The distance between the first clamping surface 21 and the second clamping surface 22 gradually decreases in the direction away from the horn 10, so that the clamping portion 20 can extend into the space for cutting tissue structures to a certain extent.
[0030] Example 3
[0031] As an optional implementation, refer to Figure 1 and Figure 2 The present embodiment provides a specific structure of a clamping portion 20, including: a water inlet channel 11 is arranged in the clamping portion 20 and the amplitude rod 10, and a water outlet hole 30 connected to the water inlet channel 11 is arranged on the first clamping surface 21 and / or the second clamping surface 22, and the water outlet hole 30 is used to spray cooling water to the first working section 41 and / or the second working section 42.
[0032] In this embodiment, by setting the water outlet 30 on the first clamping surface 21 and / or the second clamping surface 22, since the distance between the first clamping surface 21 and the second clamping surface 22 gradually decreases in the direction away from the amplitude rod 10, the water outlet 30 can spray out perpendicularly to the surface of the first clamping surface 21 or the second clamping surface 22, so that the axis extension line of the water outlet 30 intersects with the second working section 42, ensuring that the water in the water outlet 30 can be sprayed to the position of the second working section 42; when the kinetic energy of the water in the water outlet 30 is transferred during the spraying, it can flow along the first clamping surface 21 or the second clamping surface 22 to the first working section 41, so as to achieve the cleaning and cooling of the surfaces of the first working section 41 and the second working section 42. For the convenience of understanding, as Figure 1 As shown, the first working section 41 extends to the left, and at this time, the water outlet 30 can be set only on the second clamping surface 22, or can be set on both the first clamping surface 21 and the second clamping surface 22. The water outlet 30 on the first clamping surface 21 can spray onto the second working section 42, and the water outlet 30 on the second clamping surface 22 can spray onto the first working section 41. Further, multiple water outlets 30 can be set at different heights on the first clamping surface 21, and the angle between the axis of the water outlet 30 and the plane where the second working section 42 is located gradually increases from bottom to top, so as to ensure that by setting multiple water outlets 30, different positions of the second working section 42 can be sprayed for cleaning or cooling.
[0033] The first clamping surface 21 and / or the second clamping surface 22 are provided with a water outlet 30 connected to the water inlet channel 11, and the water outlet 30 is used to spray cooling water to the first working section 41 and / or the second working section 42. Specifically, the water outlet 30 can be provided only on one side of the first clamping surface 21 or the second clamping surface 22, or can be provided on both the first clamping surface 21 and the second clamping surface 22. The water outlet 30 can only flush the surface of the first working section 41 or the second working section 42, or can flush the surface of the first working section 41 or the second working section 42 at the same time.

[0036] In this embodiment, by providing the first side surface 23 and the second side surface 24 that are inwardly arc-shaped recessed on the clamping portion 20 , it is convenient for the operator to hold the first side surface 23 and the second side surface 24 to install it on the ultrasonic transducer.

In certain specific surgical procedures, the surgical tool needs to have a certain cutting ability. Surface roughening can change the microstructure of the surface of the scalpel, so that it has better cutting performance and penetration. For example, in certain surgeries, the scalpel needs to be able to penetrate the tissue quickly and accurately, and in this case, surface roughening can improve the cutting efficiency of the scalpel.
