Abstract
Description
Technical Field
[0001] This utility model relates to a medical device, and more particularly to a wolf-tooth-shaped ultrasonic debridement rod. Background Technology
[0002] Diabetic foot ulcers are one of the most common chronic complications of diabetes, with a global prevalence of 6.3%, and approximately 15% of patients face the risk of amputation. Diabetic foot ulcers are characterized by chronic, slow-healing wounds on the foot. Due to poor blood circulation and neuropathy, diabetic foot ulcers heal slowly, are prone to infection, and can lead to amputation in severe cases.
[0003] Currently, the debridement of foot ulcers mainly relies on manual tools, laser equipment, or water jet systems, but these methods have significant limitations:
[0004] 1. Manual tools (such as scalpels and curettes): rely on the surgeon's experience, are prone to damaging healthy tissue, and have a high risk of wound bleeding;
[0005] 2. Laser equipment: The thermal effect may cause carbonization of surrounding tissues, and its effectiveness in clearing deep infections is limited;
[0006] 3. Water jet system: Requires high-pressure water flow, the equipment is bulky, and not suitable for outpatient or home care scenarios. An ultrasonic transducer is a device that converts electrical energy into ultrasonic energy; it is typically used to convert electrical signals into mechanical vibrations, thereby generating ultrasonic waves.
[0007] With the continuous development of ultrasound technology, the application of ultrasonic vibration to remove necrotic tissue has gradually become a new non-invasive debridement method. However, most existing ultrasonic debridement devices are designed with regular shapes such as flat heads and spheres, which are difficult to adapt to the needs of debridement of irregular surfaces of foot ulcers and soft tissue eschar cutting. Utility Model Content
[0008] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a wolf-tooth shaped ultrasonic debridement rod to solve the technical problems existing in the prior art.
[0009] To achieve the above and other related objectives, this utility model provides a spiked club-shaped ultrasonic debridement rod, comprising at least: a spiked club structure, a working rod, and an ultrasonic transducer.

The proximal end face is smoothly connected to the head of the working rod, and the centerline of the spiked club structure along its length coincides with the centerline of the working rod along its length. The tail of the working rod is connected to the ultrasonic transducer. The spiked club structure includes a rod body and a plurality of protrusions for cutting disposed on the rod body.
[0010] Preferably, the protruding structure includes protrusions; a plurality of the protrusions are regularly arranged on the sidewall of the mace structure.
[0011] Preferably, several of the protrusions are arranged in columns to form a protrusion column, and several protrusion columns are arranged on the side wall of the rod.

[0014] Preferably, all protrusions in the same protrusion row are arranged in parallel.
[0015] Preferably, a cleaning groove is provided between adjacent rows of protrusions.
[0016] Preferably, the protruding structure further includes trapezoidal bosses; the trapezoidal bosses are evenly distributed across the distal end face.

[0038] refer to Figure 1 , Figure 4 and Figure 7 As shown, this utility model provides a club-shaped ultrasonic debridement rod, comprising at least: a club structure 2, a working rod 1, and an ultrasonic transducer 4. This club-shaped ultrasonic debridement rod is used for wound treatment, orthopedic surgery, and the treatment of diabetic foot ulcers. This club-shaped ultrasonic debridement rod not only achieves efficient cutting and mechanical scraping, but also adapts to the needs of debridement of irregular surfaces and soft tissue eschar cutting, and can precisely target the lesion site, avoiding accidental damage to healthy tissue.
[0039] Example 1: The working rod 1 is preferably made of medical-grade stainless steel or titanium alloy, as described in the wolf-tooth structure 2, which possesses good ultrasonic conduction performance and biocompatibility. (See...) Figure 1 Preferably, the length of the working rod 1 is approximately 100–150 mm, which can be adjusted according to different surgical needs.
[0040] The tail end of the working rod 1 is connected to the ultrasonic transducer 4. Preferably, the working rod 1 adopts a conical design; specifically, the sidewall between the tail end and the head end of the working rod 1 is formed by an arc surface, and the diameter of the working rod 1 gradually decreases from the tail end to the head end. This design not only ensures the mechanical strength of the working rod 1, but also facilitates the connection to the ultrasonic transducer 4, and reduces its working volume, making treatment operations easier.
[0041] refer to Figure 1The spiked club structure 2 is preferably made of medical-grade stainless steel or titanium alloy. The spiked club structure 2 includes a proximal end face and a distal end face opposite to the proximal end face. The proximal end face is smoothly connected to the head of the working rod 1, and the centerline of the spiked club structure 2 along its length coincides with the centerline of the working rod 1 along its length. Preferably, the spiked club structure 2 and the working rod 1 are integrally molded, which not only facilitates manufacturing but also maximizes the smoothness of the connection between the proximal end face and the head of the working rod 1, thereby improving the quality of treatment.
[0042] refer to Figure 1 and Figure 2 The spiked club structure 2 includes a club body and a plurality of protrusions 21 disposed on the club body for cutting. Preferably, the protrusions 21 are formed by extending outward from the sidewall of the club body, that is, the protrusions 21 and the club body are integrally formed.
[0043] refer to Figure 1 and Figure 2 The protruding structure 21 includes protrusions; a plurality of the protrusions are regularly arranged on the sidewalls of the spiked club structure 2. Preferably, the outer surface of the protrusions has a hard ceramic layer or a diamond coating to further improve cutting efficiency and wear resistance.
[0044] refer to Figure 4 and Figure 5 Several protrusions are arranged in columns to form protrusion rows 23, and several protrusion rows 23 are arranged on the side wall of the rod. Preferably, the several protrusion rows 23 are parallel to each other. Specifically, the several protrusion rows 23 are parallel to the center line of the length direction of the mace structure 2 or the angle between them is acute.
[0045] Preferably, all protrusions in the same protrusion row 23 are arranged in parallel. Specifically, several protrusions are arranged sequentially from one end of the rod to the other to form a protrusion row 23, see... Figure 5 More preferably, the height of the protrusion is 0.2 to 1.5 mm, and the distance between two adjacent protrusions is 0.5 to 3 mm.
[0046] Preferably, the protrusion is an arc-shaped serration, and the arc-shaped serration includes a convex arc surface 211 and a concave arc surface 212 opposite to the convex arc surface 211. Preferably, both the concave arc surface 212 and the convex arc surface 211 are formed by minor arcs, see... Figure 5 .
[0047] refer to Figure 4 and Figure 5The intersection of the free end of the concave arc surface 212 and the free end of the convex arc surface 211 forms the cutting tooth tip 213; the intersection of the fixed end of the concave arc surface 212 and the fixed end of the convex arc surface 211 forms the tooth root, and all the cutting tooth tips 213 in the same row of protrusions 23 are parallel to each other; the tooth root of the bow-shaped saw tooth is connected to the rod body; preferably, the thickness of the bow-shaped saw tooth gradually increases from the cutting tooth tip 213 to the tooth root. This not only ensures the mechanical strength of the bow-shaped saw tooth, but also ensures its cutting performance.
[0048] The protruding structure 21 also includes polygonal bosses, and the dimensions of the polygonal bosses gradually increase from the upper surface to the lower surface. The polygonal bosses cover the distal end face of the spiked club structure 2.
[0049] Preferably, refer to Figure 4 and Figure 5 The polygonal protrusion is a trapezoidal protrusion 22; the trapezoidal protrusions 22 are evenly distributed across the distal surface of the wolf-tooth structure 2. Preferably, the height of the trapezoidal protrusion 22 is 0.2–1.5 mm, and the distance between two adjacent trapezoidal protrusions 22 is 0.5–3 mm.
[0050] Specifically, the trapezoidal protrusions 22 are arranged in a grid pattern on the distal end face of the wolf-tooth structure 2, thereby greatly improving the cutting quality. More preferably, the outer surface of the trapezoidal protrusions 22 has a hard ceramic layer or a diamond coating, further improving cutting efficiency and wear resistance.
[0051] Example 2, Reference Figure 3 The main difference between this embodiment and the previous embodiment is that a liquid supply port 31 is provided on the side wall of the working rod 1. The liquid supply port 31 is connected to a liquid supply device, which continuously supplies liquid to the liquid supply port 31 during operation. A liquid delivery channel 32 is provided in the working rod 1, and the input end of the liquid delivery channel 32 is connected to the liquid supply port 31. The output port 33 of the liquid delivery channel 32 is preferably located at the connection between the spiked club structure 2 and the working rod 1. The cleaning liquid flowing from the output port 33 of the liquid delivery channel 32 continuously flows to the spiked club structure 2.
[0052] Meanwhile, a cleaning groove 24 is provided between adjacent rows of protrusions 23, see Figure 8 Used to guide the flow of liquid under ultrasonic vibration, it can quickly remove debris and keep the operating area clean.
[0053] During operation, the ultrasonic transducer 4 generates electrical signals that are converted into mechanical vibrations, which are then transmitted to the spiked rod structure 2 via the working rod 1. The spiked rod structure 2 performs scraping operations on the tissue to be treated. Simultaneously, the liquid supply device introduces cleaning fluid from the supply port 31 into the infusion channel 32. The cleaning fluid flows through the infusion tube and through the output port 33 to the spiked rod structure 2. At the output port 33, the cleaning fluid is atomized by ultrasonic action, generating micron-sized droplets that form a diffuse spray. These micron-sized droplets cover the spiked rod structure 2, and finally, the cleaning fluid flows out from the cleaning tank 24, carrying away debris and other contaminants. This effectively maintains the cleanliness and disinfection of the operating area.
[0054] This embodiment 3 differs from the previous embodiments mainly in that, referring to... Figure 7 The wound cleaning rod of this utility model also includes an artificial mechanical handle 5; the ultrasonic transducer 4 includes an ultrasonic body and an ultrasonic generator (not shown in the figure) electrically connected to the ultrasonic body; the ultrasonic body is housed within the artificial mechanical handle 5. The electrical wire 6 of the ultrasonic body extends from the rear end of the artificial mechanical handle 5 and is electrically connected to the ultrasonic generator; the electrical wire 6 includes power supply and signal lines, etc.
[0055] The manual force handle 5 is engaged or threadedly connected to the tail of the working rod 1. Preferably, refer to Figure 6 The working rod 1 includes a first rod 12 and a second rod 11. The diameter of the first rod 12 is smaller than the diameter of the second rod 11. The tail of the second rod 11 is connected to the ergonomic handle 5, and the head of the second rod 11 is smoothly connected to the tail of the first rod 12. The first rod 12 and the second rod 11 are integrally formed.
[0056] Preferably, the centerline of the first rod 12 is collinear with the centerline of the second rod 11 and the centerline of the artificial mechanical handle 5.
[0057] In addition, an antibacterial coating can be added to the surface of the working rod 1 to reduce the risk of infection during surgery.
[0058] This invention can be used in multiple medical scenarios, such as:
[0059] ① Surgical debridement: In wound care, orthopedic debridement, diabetic foot ulcers, burn debridement, etc., ultrasonic debridement can effectively remove necrotic tissue, protect healthy tissue, reduce patient pain and promote healing.
[0060] ② Dental care: Used for periodontal disease treatment and tartar removal. Ultrasonic debridement can remove bacteria and tartar near the gums and reduce gum damage.
[0061] ③ Tumor resection: Ultrasonic debridement technology can be used in tumor tissue resection to precisely remove specific lesion areas while protecting surrounding normal tissues.
[0062] This invention can also be applied to fields such as industrial cleaning and archaeological artifact preservation, for example, to precisely remove surface dirt, rust, and residues.
[0063] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
