[0024] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.

[0025] The ultrasonic hemostatic knife head structure includes a knife head portion 1, which is used to be docked with a knife rod 2; the knife head portion 1 has two guide surfaces 11 and two working surfaces 12, the two guide surfaces 11 are arranged correspondingly at both ends, and the two working surfaces 12 are arranged correspondingly at both ends, and the working surfaces 12 are used for ultrasonic operations; along the direction away from the knife rod 2, the lateral spacing between the two guide surfaces 11 is gradually reduced, and the lateral spacing between the two working surfaces 12 is gradually reduced.

[0026] The above-mentioned ultrasonic hemostatic knife head structure, under the action of the two guide surfaces 11, reduces the working distance and working space, reduces the surgical wound, and at the same time reduces the sharpness, thereby avoiding accidental injury to human tissue and avoiding secondary injury to the patient. Under the action of the two working surfaces 12, it is convenient to gather ultrasonic energy and improve the hemostatic effect. At the same time, the working surface 12 is arranged at an angle, the field of view of the ultrasonic surgery is clearer, the safety of the ultrasonic surgery is better, and the working surface 12 is arranged in this way, so that the ultrasonic force distribution is more uniform, thereby improving the coagulation effect and the hemostatic effect.

[0027] The outer ends of the two working surfaces 12 are butt-jointed to form a tip portion 13, and the tip portion 13 is arched in an arc shape in a direction away from the knife rod 2. In this way, the arc arrangement of the tip portion 13 allows more heat to be transferred from the knife rod 2 to the tip portion 13, and then from the tip portion 13 to the human tissue, making the effect of coagulating blood vessels better and more reliable.

[0028] The inner end of the working surface 12 is butt-jointed with the guide surface 11 to form an inner connecting portion 14, and the inner connecting portion 14 is arched in an arc shape in a direction away from the knife rod 2; in this way, the inner connecting portion 14 can transfer more heat to the working surface 12, so that the effect of coagulating blood vessels is better and more reliable through the working surface 12.

[0029] The two working surfaces 12 are arranged in the shape of arched curved surfaces in opposite directions; thus, the working surfaces 12 have a larger working area, thereby improving the efficiency and effect of the ultrasonic operation.

[0030] An angle is formed between the working surface 12 and the guide surface 11, and the angle is an obtuse angle, which facilitates the cooperation between the guide surface 11 and the working surface 12 and facilitates ultrasonic operation.

[0031] The guide surface 11 is arranged in a fan shape, and the cross-sectional area of ​​the guide surface 11 gradually increases in the direction away from the knife rod 2. In this way, the closer to the tip of the guide surface 11, the larger the working area, making the effect of coagulating blood vessels better and more reliable.

[0032] The two working surfaces 12 are arranged centrally and symmetrically, which facilitates the manipulation of the two working surfaces 12 and makes the ultrasonic energy transmission more uniform, thereby improving the efficiency and safety of hemostasis.

[0033] The two guide surfaces 11 are arranged in a central symmetric manner, so that the ultrasonic energy is transmitted more evenly and the ultrasonic energy is transmitted to the working surface 12 more evenly.

[0034] The cutter head 1 and the cutter rod 2 are integrally formed, which facilitates the transmission of ultrasonic energy and improves the efficiency and effect of ultrasonic energy transmission.

[0035] The guide surface 11 extends to the knife bar 2 , thereby increasing the operating range of the guide surface 11 .

[0036] The cutter head 1 includes an upper cutter surface and a lower cutter surface, which are arranged at intervals and correspondingly, and along the axial direction of the cutter rod 2, the upper cutter surface and the lower cutter surface are arranged to extend obliquely in a flared shape, which facilitates the diffusion of ultrasonic energy toward the working surface 12 and helps to increase the energy diffusion range.

[0037] Along the radial direction of the tool rod 2, the two ends of the upper tool surface are respectively docked with the two guide surfaces 11, the two ends of the lower tool surface are respectively docked with the two guide surfaces 11, and the front end of the upper tool surface is synchronously docked with the two working surfaces 12, and the front end of the lower tool surface is synchronously docked with the two working surfaces 12.

[0038] In this way, the upper cutting surface, the two guide surfaces 11, the two working surfaces 12 and the lower cutting surface are easily matched with each other.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
