[0002] An ultrasonic transducer is a device that can convert electrical energy into ultrasonic energy, typically used to convert electrical signals into mechanical vibrations, and then generate ultrasonic wave fluctuations.

[0003] Diabetic foot ulcers are a common complication of diabetes, characterized by chronic, difficult-to-heal foot wounds. Due to poor blood circulation and neuropathy, diabetic foot ulcers heal slowly and are prone to infection, and in severe cases can lead to amputation. Currently, debridement of foot ulcers relies mainly on manual tools or laser equipment, but there are problems such as low efficiency, easy damage to healthy tissue, and inconvenient operation.

[0034] As shown in Figure 1 , the present application provides a multifunctional saw-shaped ultrasonic debridement working rod, which comprises a connecting rod 1 and an ultrasonic transducer 2.

[0035] Referring to Figures 1 to 7 , the connecting rod 1 is made of medical stainless steel or titanium alloy, which has good ultrasonic transmission performance and biocompatibility. The tail of the connecting rod 1 is arranged with a handle 3; the head of the connecting rod 1 has a blade 11 for cutting tissue, and the blade 11 has a blade edge formed by a plurality of saw teeth 12. Compared with the ordinary blade edge, the blade edge formed by a plurality of saw teeth 12 can enhance the cutting effect on necrotic tissue, while avoiding excessive damage to healthy tissue.

[0036] Reference Figure 1 The ultrasonic transducer 2 is installed in the handle 3 and connected to the tail of the connecting rod. When the ultrasonic transducer 2 works, it can drive the connecting rod 1 to vibrate ultrasonically, and then make the tool head 11 vibrate ultrasonically, so as to adapt to different hardness and types of necrotic tissue, and further improve the cutting effect and application range.

[0037] In the present application, as shown in Figure 2 and Figure 3 , the tool head 11 has an upper surface 13 and a lower surface 14. The upper surface 13 is a concave arc surface, and the lower surface 14 is a smooth surface. Preferably, the tool head 11 is approximately boat-shaped.

[0038] The upper surface 13 of the tool head 11 has a flushing hole 15, which can deliver flushing liquid to the tool head 11, as shown in Figure 2 .

[0039] In the present application, the tool head 11 can only have the cutting edges at the front end; preferably, the front end, left side and right side of the tool head 11 are all covered with the cutting edges; the cutting edges are in the shape of a door. The cutting edges are formed by a plurality of sawteeth 12, as shown in Figure 3 and Figure 6 ; preferably, the spacing of the sawteeth 12 is 0.5-3mm, and the depth is 0.2-1.5mm. The shape of the sawteeth 12 can be diversified, such as wavy, hooked or gradually changing in height.

[0040] Part of the sawteeth 12 is made of hard ceramic or diamond coating, which further improves the cutting efficiency and wear resistance.

[0041] Further, as shown in Figure 2 and Figure 3 , the thickness of the tool head 11 decreases from the rear end to the front end of the tool head 11. The tool head 11 and the connecting rod 1 can be designed as a split type to facilitate the replacement of the appropriate tool head 11 according to different scenarios, so as to adapt to different debridement scenarios, such as large area of necrotic tissue or deep and narrow wound, etc. The tool head 11 and the connecting rod 1 can be designed as a split type, which is convenient, can improve efficiency and avoid cross infection. Of course, the tool head 11 and the connecting rod 1 can also be designed as a whole.

[0042] Reference Figure 2 , Figure 6 and Figure 7The rear end of the blade head 11 has a cutting surface 131, and the outlet of the flushing hole 15 is located at the intersection of the cutting surface 131 and the upper surface 13 of the blade head 11; preferably, the cutting surface 131 is smoothly connected with the upper surface 13 of the blade head 11. A liquid supply pipe 4 is arranged in the connecting rod 1, the input port 41 of the liquid supply pipe 4 is arranged on the outer wall of the connecting rod 1 and connected with a liquid supply device, and the output port of the liquid supply pipe 4 is connected with the flushing hole 15. Preferably, the center line of the liquid supply pipe 4 is collinear with the center line of the connecting rod 1.

[0043] In this application, as shown in the drawings, a groove 16 is arranged between two adjacent saw teeth 12. This groove 16 not only guides the flow of flushing liquid, but also has a debris removal function. Figure 2

[0044] During the operation, the liquid supply pipe 4 in the connecting rod 1 continuously supplies cleaning liquid to the flushing hole 15, and after the cleaning liquid flows to the upper surface 13 of the blade head 11 through the flushing hole 15, it then flows to the blade edge, and the groove 16 guides the flow of the cleaning liquid, realizing the cooperative operation of ultrasonic debridement and synchronous flushing.

[0045] In order to reduce the risk of infection during the operation, an antibacterial coating is usually added to the surface of the connecting rod 1.

[0046] In this application, the length and diameter of the connecting rod 1 and the design of the handle 3 are all ergonomically designed to facilitate surgical operation and reduce the fatigue of the surgeon. The length of the connecting rod 1 is usually about 100-150 mm, and can be adjusted according to different surgical needs.

In addition, the liquid supply pipe 4 in the connecting rod 1 continuously supplies cleaning liquid to the flushing hole 15, the groove 16 guides the flow of the cleaning liquid, realizes the cooperative operation of ultrasonic debridement and flushing, and greatly improves the cutting effect.
