Abstract

The invention discloses an external ultracision harmonic scalpel which comprises a support, a handle and an outer barrel. The handle is rotationally connected to the rear of the support, the outer barrel is connected onto the support and penetrates the inside of the support, an inner barrel is connected onto the handle, is nested in the outer barrel and is connected with the handle by a rotary rod, an accommodating groove which provides a rotation space for the rotary rod is formed in the rear end surface of the outer barrel, the rotary rod can be accommodated in the accommodating groove, a vertically rotatable upper jaw plate is rotationally connected to the front end of the inner barrel, a lower jaw plate which is arranged below the upper jaw plate is connected to the front end of the outer barrel, and a protrusion with a curved surface is arranged on the lower side of the rear of the upper jaw plate and is tangential to the upper surface of the lower jaw plate. The external ultracision harmonic scalpel has the advantages that the external ultracision harmonic scalpel is provided with the handle and the support, the outer barrel can extend into a surgical wound of a patient, the handle is pushed to drive the upper jaw plate to be opened and closed, accordingly, a small wound in the surgical wound of the patient is opened, then an ultrasonic generating device on an opening in the rear end of the inner barrel is started and switched on, ultrasonic wave bands are transmitted into the surgical wound via the inner barrel, and an ultrasonic hemostasis effect can be realized; the external ultracision harmonic scalpel is high in accuracy and efficiency when used for treatment.

Example Embodiment

[0013] Such as figure 1 , figure 2 , image 3 with Figure 4 Shown is a structural schematic diagram of an embodiment of the present invention, an external ultrasonic cutting hemostatic knife, comprising a bracket 2, a handle 1 rotatably connected to the rear of the bracket 2, and an outer tube 3 connected to the bracket 2 and penetrating the inside of the bracket 2. The handle 1 is connected with an inner tube 6, the inner tube 6 is sleeved in the outer tube 3, the inner tube 6 and the handle 1 are connected by a rotating rod 9, and the rear end of the outer tube 3 is provided with a housing The accommodating slot 10 for the rotation space of the rotating rod 9 is provided. The front end of the inner cylinder 6 is rotatably connected with an upper jaw plate 4, and the front end of the outer cylinder 3 is connected with a lower jaw plate 5 that can rotate up and down. The lower jaw plate 5 is arranged under the upper jaw plate 4. The lower side of the rear part of the upper jaw 4 is provided with a curved protrusion 8, and the curved protrusion 8 is tangent to the upper surface of the lower jaw 5. When the handle 1 is pulled, the handle 1 drives the inner tube 6 and pushes the inner tube 6 forward, and the upper jaw 4 is opened upward under the action of the curved protrusion 8.

[0014] In this embodiment, the handle 2 and the outer cylinder 3 are rotatably connected by a shaft 7.

[0015] The lower surface of the upper jaw 4 is provided with oblique zigzag protrusions 11. It is designed to be used in the diagnosis and treatment process. There are fragments of tissue in the wound, which is easy to clip out.

[0016] In this embodiment, during the operation process, the handle 1 and the holder 2 are controlled, the outer tube 3 is extended into the wound, and the upper jaw 4 is opened and closed by pushing and pulling the handle 1, thereby supporting the small wound in the mouth, and then opening the mouth. Passing through the ultrasonic generating device on the opening of the rear end of the inner tube 6, the ultrasonic wave band is transmitted to the wound through the inner tube 6 to complete ultrasonic hemostasis. The treatment is precise and efficient.

[0017] In addition to the above-mentioned preferred embodiments, the present invention has other embodiments. Those skilled in the art can make various changes and modifications according to the present invention. As long as they do not deviate from the spirit of the present invention, they should all be defined by the appended claims of the present invention. range.
