Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ultrasonic debridement device. Background Art

[0002] In the medical field, ultrasonic debridement technology has become a very important treatment method. Ultrasonic debridement technology uses low-frequency ultrasound to produce a "cavitation effect" in the flushing jet fluid, and specifically cavitates and blasts the bacterial biofilm formed in the femoral medullary cavity, generating a shear force at the junction of solid and liquid to remove bacteria, viruses and fungi deep in the femoral medullary cavity. By combining surgical debridement with low-frequency ultrasonic technology, the medical staff can improve the wound bacteria and biofilm removal rate during surgery.

[0003] Current ultrasonic debridement devices use an ultrasonic probe inserted into the femoral medullary cavity to cavitate and blast the bacterial biofilm within the medullary cavity, thereby removing bacteria, viruses, and fungi deep within the femoral medullary cavity. During the debridement procedure, the ultrasonic probe must be in a liquid environment. However, because existing ultrasonic debridement devices lack a liquid supply function, debridement fluid must be supplied to the medullary cavity through other fluid supply devices. After the debridement procedure is completed, the debridement fluid must be withdrawn using a negative pressure suction device. Due to the limited space within the medullary cavity, the debridement process requires multiple injections and withdrawals, which prolongs the entire debridement process and places an additional burden on the patient. Summary of the Invention

[0004] The purpose of the utility model is to provide an ultrasonic debridement device capable of forming a debridement liquid circulation to improve the debridement effect.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0023] The following will be combined with the accompanying drawings to describe in detail the preferred embodiments of the present invention so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0024] In the following description, for the purpose of illustrating the various disclosed embodiments, certain specific details are set forth in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with this application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0025] Unless the context requires otherwise, throughout the specification and claims, the word "comprise" and variations such as "include" and "have" should be construed in an open, inclusive sense, that is, should be interpreted to mean "including, but not limited to."

[0026] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0027] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. It should be noted that the term "or" is generally employed in its sense including "and / or" unless the context clearly dictates otherwise.

[0028] In the following description, in order to clearly demonstrate the structure and working mode of the present invention, many directional words will be used for description, but words such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and should not be understood as restrictive terms.

[0029] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0030] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense.

[0031] like Figure 1-Figure 2 As shown, this embodiment provides an ultrasonic debridement device, including a main unit 1 and a treatment head 2. The treatment head 2 is connected to the main unit 1 through an electrical connection line 3. The treatment head 2 includes a handle 21, a transducer head 22 and a tool head 23. One end of the transducer head 22 is connected to the handle 21, and the other end is connected to the tool head 23. An angle is formed between the longitudinal axis of the transducer head 22 and the longitudinal axis of the handle 21. The angle is preferably 70-120°, and more preferably 90°. During hip revision surgery, the tool head 23 sometimes needs to be partially extended into the bone marrow cavity. In the traditional design, the handle 21, the tool head 23 and the transducer head 22 are arranged in a straight line, resulting in that during the debridement process, only the easily accessible infected areas can be debridement. Some corner areas cannot be reached by the treatment head 2, and it is difficult to achieve a sufficient debridement effect. In this embodiment, the end of the transducer head 22 is connected to the end of the handle 21, and the handle 21 is arranged at an angle to the transducer head 22, making it easier for the surgeon to operate during surgery and allowing for debridement in corner areas. This significantly expands the scope of debridement, making debridement more comprehensive and improving the efficiency and thoroughness of debridement during surgery. To facilitate better operation of the transducer head 22 and the tool head 23, the end of the handle 21 is provided with a connecting portion, which has a connecting hole within it, and the transducer head 22 is detachably connected to the connecting hole.

[0032] See also Figure 3-Figure 5The ultrasonic debridement device in this embodiment also includes a separating sleeve 24, which includes an outer tube 241 and an inner tube 242 extending in the axial direction. The outer tube 241 and the inner tube 242 are fixedly connected at their axial ends. A gap is provided between the outer tube 241 and the inner tube 242, forming a closed annular space between the outer tube 241 and the inner tube 242. A partition 243 is also provided in the annular space, which divides the annular space into a first channel 244 and a second channel 245, which are isolated from each other. A first water inlet 2441 is provided at the rear end of the first channel 244, and a first water outlet 2442 is provided at the front end of the first channel. A second water inlet 2451 is provided at the front end of the second channel 245, and a second water outlet 2452 is provided at the rear end of the second channel. The first water inlet 2441 is connected to a container for storing debridement fluid through a pipeline, and the debridement fluid is pumped into the first channel 244 by means of a device such as a peristaltic pump, and then flows into the patient's medullary cavity through the first water outlet 2442 provided at the front end. The second water outlet 2452 is connected to a negative pressure suction machine through a pipeline, allowing the debridement fluid in the medullary cavity to flow from the second water inlet 2451 into the second channel 245 and be drained to the body position by the negative pressure suction machine. By balancing the flow rate pumped in by the peristaltic pump and the flow rate sucked out by the negative pressure suction machine, the debridement fluid containing pathogens is continuously discharged and fresh debridement fluid is replenished, forming a debridement fluid circulation in the patient's medullary cavity, which can reduce the residual pathogens in the body and improve the debridement effect. In addition, the flowing debridement fluid can also have a cooling effect on the ultrasonic probe. It should be understood that the separation sleeve 24 in this embodiment can be formed by welding two semicircular pipes, or it can be directly manufactured using processes such as extrusion molding.

[0033] The inner diameter of the inner tube 242 is comparable to the outer diameter of the transducer head 22, so that the inner tube 242 can be sleeved and fixed on the transducer head 22. Preferably, the separation sleeve 24 is made of rubber or silicone material with a certain degree of elasticity, and the inner tube 242 and the transducer head 22 are fixedly connected by an interference fit, so that the separation sleeve 24 can be sleeved and fixed on the transducer head 22 during surgery.

[0034] See also Figure 5 The length of the separation sleeve 24 is smaller than the length of the tool head 23 so that the front end of the tool head 23 can extend beyond the front end of the separation sleeve 24 to facilitate better debridement of the patient's wound.

[0035] See also Figure 3 and Figure 5 The length of the outer tube body 241 of the separation sleeve 24 is greater than the length of the inner tube body 242. The rear ends of the outer tube body 241 and the inner tube body 242 are arranged flush, so a tapered inclined surface is formed at the front end, and the first water outlet 2442 and the second water inlet 2451 are both arranged on the inclined surface.

[0036] While the preferred embodiments of the present invention have been described in detail above, it should be understood that, after reading the above teachings of the present invention, those skilled in the art may make various changes or modifications to the present invention. Such equivalents also fall within the scope of the claims appended hereto.
