Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a spoon-shaped ultrasonic debridement rod. Background Technology
[0002] In the medical field, diabetic foot ulcers are a common complication of diabetes, characterized by chronic, slow-healing foot wounds. Due to poor blood circulation and neuropathy, diabetic foot ulcers heal slowly, are prone to infection, and can lead to amputation in severe cases. Therefore, diabetes treatment requires precise, efficient, and minimally invasive procedures to reduce patient pain and accelerate wound healing. Similarly, surgical wound management also requires precise, efficient, and minimally invasive procedures.
[0003] The debridement of foot ulcers mainly relies on manual tools or laser equipment, but this method has problems such as low efficiency, easy damage to healthy tissue, and inconvenience in operation.
[0004] 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. With the continuous development of ultrasonic technology, the application of ultrasonic vibration to remove necrotic tissue has gradually become an emerging non-invasive debridement method. However, most existing ultrasonic debridement devices have regular designs such as flat-headed or spherical shapes, which are difficult to adapt to the needs of debridement of irregular surfaces of foot ulcers and the cutting of soft tissue eschar.

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0032] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0033] This invention provides a spoon-shaped ultrasonic debridement rod; the ultrasonic debridement rod has both debridement and cutting functions.
[0034] like Figure 1 , Figure 2 ,and Figures 4 to 6 As shown, the spoon-shaped ultrasonic debridement rod provided by this utility model includes at least: a spoon head structure 1, a working rod 2, and an ultrasonic transducer 3.
[0035] The working rod 2 is made of medical-grade stainless steel or titanium alloy, possessing excellent ultrasound conduction performance and biocompatibility. The specific length of the working rod 2 can be adjusted according to different surgical needs. A length of 80–200 mm is designed to meet the requirements of most medical scenarios. Additionally, an antibacterial coating can be added to the surface of the working rod to reduce the risk of intraoperative infection.
[0036] In Example 1, the head of the working rod 2 is provided with the spoon head structure 1, and the tail of the working rod 2 is connected to the ultrasonic transducer 3;
[0037] refer to Figures 1 to 4 The upper end face 11 of the spoon head structure 1, away from the working rod 2, has several serrated structures 101. These serrated structures 101 enhance the cutting effect on necrotic tissue while avoiding excessive damage to healthy tissue. Preferably, the serration spacing of the serrated structures 101 is typically designed to be no more than 5 mm, and the length of the serrations is typically no more than 3 mm. The spoon head structure 1 is made of medical-grade stainless steel or titanium alloy, and possesses good ultrasonic conductivity and biocompatibility.
[0038] Preferably, the thickness of the sawtooth structure 101 gradually increases from the tooth tip to the tooth root; this design is more conducive to the scraping and removal of debris.
[0039] The spoon head structure 1 extends downward from the upper end face 11 to form a sidewall, and the lower ends of the sidewall converge towards the center to form the spoon bottom 12; that is, the sidewall and the spoon bottom 12 enclose a hemispherical receiving space, see Figure 1 .
[0040] Preferably, refer to Figure 2 and Figure 3 A cleaning groove 102 is provided between the roots of two adjacent serrated structures 101, and the cleaning groove 102 extends through the sidewall. In other words, the cleaning groove 102 connects the receiving space of the spoon head structure 1 and the external space of the spoon head structure 1. Debris generated during operation can fall into the cleaning groove 102, thereby keeping the operating area clean.
[0041] In order to improve the quality of treatment and reduce the volume, this application designs the upper end face 11 of the spoon head structure 1 to be parallel to the center line of the working rod 2.
[0042] refer to Figure 1 and Figure 2The spoon head structure 1 is smoothly connected to the working rod 2. Specifically, the spoon head structure 1 and the working rod 2 are integrally formed, or the spoon head structure 1 and the working rod 2 are connected by a snap-fit structure, or the spoon head structure 1 and the working rod 2 are connected together by threads, or they are connected together by welding.
[0043] Preferably, the thickness of the spoon head structure 1 gradually increases from the upper end face 11 of the spoon head structure 1 to the bottom 12 of the spoon head structure 1. This ensures that the working part of the serrated structure 101 is relatively thin and sharp, which is more conducive to the scraping and removal of debris.
[0044] In this embodiment 2, refer to Figure 3 and Figure 5 The main difference between this embodiment and the previous embodiment is that the working rod 2 has a liquid supply port 41 on its side wall, and an infusion channel 42 is provided in the working rod 2, with the input end of the infusion channel 42 connected to the liquid supply port 41. The liquid supply port 41 is connected to a liquid supply device (not shown in the figure), which continuously supplies medical fluid to the liquid supply port 41 during operation. The medical fluid enters the infusion channel 42 through the liquid supply port 41, flows through the infusion tube, and then flows into the spoon head structure 1 through the liquid outlet 43.
[0045] During operation, the ultrasonic transducer 3 generates electrical signals that are converted into mechanical vibrations, which are then transmitted to the spoon head structure 1 by the working rod 2. The spoon head structure 1 performs scraping operations on the tissue to be treated. Simultaneously, the liquid supply device inputs the cleaning solution from the supply port 41 into the infusion channel 42. The cleaning solution flows into the spoon head structure 1 through the infusion tube and outlet 43. The cleaning solution is atomized by ultrasound in the ultrasonic cleaning rod, generating micron-sized droplets within the spoon head structure 1, forming a diffuse spray. Finally, the cleaning solution flows out from the spoon head structure, carrying away debris, thus greatly improving the effectiveness of rinsing and disinfection. Furthermore, because a cleaning groove 102 is provided between the roots of adjacent serrated structures 101, debris falling into the cleaning groove 102 can also be quickly carried away by the atomized cleaning solution, thereby keeping the operating area clean. The cleaning solution has bactericidal and wound-healing properties.
[0046] Preferably, the diameter of the circumference where the tooth tip of the serrated structure 101 is located is larger than the diameter of the circumference where the tooth root of the serrated structure 101 is located. This facilitates the cleaning fluid in quickly carrying away debris, greatly improving the effectiveness of rinsing and disinfection.
[0047] The amplitude of the ultrasonic transducer 3 is adjustable to achieve the purpose of cleaning and cutting necrotic tissue and eschar, adapting to necrotic tissue of different hardness and type. For example, when used for debridement of burn wounds, the amplitude of the ultrasonic transducer 3 is adjusted to 25kHz, and the front end of the serrated structure 101 gently touches the necrotic tissue. Combined with sterile saline rinsing, the operating area is quickly cleaned without significant wound extension.
[0048] When used for deep debridement of diabetic foot ulcers, the amplitude of the ultrasonic transducer 3 is adjusted to 25kHz, and the serrated structure 101 is used to precisely clean necrotic tissue in the wound, resulting in a smooth wound surface and no damage to surrounding healthy tissue.
[0049] This embodiment 3 differs from the previous embodiments mainly in that, as referenced... Figure 6 The debridement lever of this utility model also includes an artificial mechanical handle 5; the ultrasonic transducer 3 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.
[0050] Preferably, the manual mechanical handle 5 is snapped or threaded to the tail of the working rod 2.
[0051] Preferably, refer to Figure 4 The working rod 2 includes a first rod 21 and a second rod 22. The diameter of the first rod 21 is smaller than the diameter of the second rod 22. The tail of the second rod 22 is connected to the ergonomic handle 5, and the head of the second rod 22 is smoothly connected to the tail of the first rod 21. The first rod 21 and the second rod 22 are integrally formed.
[0052] Preferably, the centerline of the first rod 21, the centerline of the second rod 22, and the centerline of the artificial mechanical handle 5 are collinear.
[0053] This invention can be used in multiple medical scenarios, such as:
[0054] 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.
[0055] 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.
[0056] ③ Tumor resection: Ultrasonic debridement technology can be used in tumor tissue resection to precisely remove specific lesion areas while protecting surrounding normal tissues.
[0057] 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.
[0058] 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.
