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 equipment uses an ultrasonic probe inserted into the femoral medullary cavity to cavitate and blast the bacterial biofilm in the medullary cavity, thereby removing bacteria, viruses, and fungi deep inside the femoral medullary cavity. However, since the specific conditions inside the medullary cavity cannot be observed during surgery, it is difficult to determine whether the bacterial biofilm in the medullary cavity has been completely removed, and this procedure relies heavily on the doctor's experience. In addition, the degree of damage to different areas during surgery often varies significantly, requiring doctors to possess a high degree of operational skill and precise judgment during treatment to avoid accidental injury to healthy tissue or inadequate debridement. However, in actual operation, this ideal state is often difficult to achieve due to various reasons. Moreover, due to the particularity and complexity of the surgical site, it is often difficult to completely cover all areas that need to be treated during the debridement process, thus affecting the debridement effect.

[0004] While arthroscopy can be used in some cases to observe intramedullary trauma, it often requires the doctor to adjust the position of the handheld arthroscopy to observe different locations within the medullary cavity. This can cause interference between the debridement device's treatment tip and the arthroscope, hindering the doctor's operation. Furthermore, in treatment scenarios with small medullary cavities, simultaneous insertion of both the arthroscope and the treatment tip is impractical, requiring the doctor's skill and judgment to perform the appropriate treatment. Therefore, improvements to existing ultrasonic debridement devices are necessary. Utility Model Content

[0037] like Figure 1-Figure 3 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 and the transducer head 22 are arranged at an angle, which makes it more convenient for the doctor to operate during the operation. Some corner areas can also be cleaned, thereby significantly expanding the scope of debridement, making the debridement more comprehensive, and improving the efficiency and thoroughness of debridement during the operation.

[0038] The general structure of the insertion end of the arthroscope 4 is as follows Figure 3 As shown, an arthroscope is an endoscope with a lighting device installed at the end, including an arthroscope lens, a camera, a light source access port and a light source line, a display, an image storage device, etc. The light source can be inserted into the femoral medullary cavity through the light source line, so that the structure inside the femoral medullary cavity is displayed on the screen in the form of an enlarged image. Since the image is enlarged, the location of the bacterial biofilm in the medullary cavity can be better observed, and whether the bacterial biofilm in the medullary cavity has been completely removed after the treatment head 2 performs debridement treatment can be observed. The visual ultrasonic debridement device can make it easier for doctors to debride the patient's wound. Since the arthroscope is a prior art, its specific structure and principle will not be described here.

[0039] See also Figure 4 and Figure 5 The ultrasonic debridement device of this embodiment also includes a positioning device 5, which includes a fixing member 51, a strap (not shown in the figure), a positioning member 53 and a locking member 54. The fixing member 51 is used to be fixed to the vicinity of the patient's affected area through a strap. The fixing member 51 includes a rigid first fixing portion 511 and a flexible second fixing portion 512, and the second fixing portion 512 is fixed to the bottom of the first fixing portion 511. The first fixing portion 511 is usually made of stainless steel, and the second fixing portion 512 can be made of rubber, silicone and other materials. The flexible second fixing portion 512 contacts the human body and can produce a certain deformation, which can increase the comfort of the fixing member 51 when it is fixed on the patient's body. The second fixing portion 512 and the first fixing portion 511 can be fixed by bonding, screw locking and other methods.

[0040] The fixing member 51 is also provided with a ball socket 513 in the middle and a through hole 514 extending through the thickness of the fixing member 51, communicating with the ball socket 513. The fixing member 51 is provided with fixing holes 515 on both sides for securing the strap. One end of the strap 52 passes through the corresponding fixing hole 515 and is fixedly connected to the fixing member 51. In this embodiment, the first fixing portion 511 is rectangular, with a boss 516 provided in the middle, on which the ball socket 513 is located.

[0041] The positioning member 53 is a spherical or spherical segment-shaped ball head that matches the ball socket 513. The positioning member 53 is rotatably mounted within the ball socket 513 via the ball head, allowing the positioning member 53 to rotate within the ball socket 513. The positioning member 53 is further provided with a first positioning hole 531 and a second positioning hole 532 that pass through the positioning member 53. The axes of the first positioning hole 531 and the second positioning hole 532 intersect at a point A outside the through hole 514.

[0042] The locking member 54 is used to fix the angle of the positioning member 53 within the ball socket 513. In this embodiment, the locking member 54 is a locking bolt. The boss 516 is provided with a screw hole 517 that communicates with the ball socket 513. The locking bolt is screwed into the screw hole 517. The front end of the bolt contacts the positioning member 53 to lock the positioning member 53.

[0043] When performing debridement on the medullary cavity during surgery, first fix the positioning device 5 to the patient's affected area with a strap, and make the through hole 514 on the fixing member 51 correspond to the puncture channel. Then the front end of the arthroscope 4 is inserted into the medullary cavity through the first positioning hole 531. At this time, the locking bolt is in a loose state, allowing the positioning member 53 to rotate in the ball socket 513. The rotation of the positioning member 53 in the ball socket 513 allows the arthroscope 4 to capture different positions in the medullary cavity. When it rotates to the wound site, tighten the locking member 54 to lock the positioning member 53 in the ball socket 513 so that the positioning member 53 cannot rotate. Then insert the treatment head 2 of the ultrasonic debridement device into the medullary cavity through the second positioning hole 532 to perform debridement on the wound site. The arthroscope 4 can be used to easily locate the patient's trauma location, and the positioning device 5 can be used to locate the trauma location, making it convenient for the doctor to perform debridement treatment on the trauma site through the treatment head 2. With the help of the positioning device 5, the doctor's operating skills and judgment during the treatment process can be reduced, allowing doctors with less operating experience to achieve good debridement effects.

[0044] See also Figure 6Because the stem at the front end of the arthroscope 4 has different diameters, such as 5mm, 8mm, and 10mm, the tool head 23 of the treatment head 2 also has different sizes, such as 6mm, 10mm, and 15mm. To facilitate the fixation of arthroscopes and treatment heads 2 of different sizes, the positioning device 5 also includes a positioning sleeve 55. The positioning sleeve 55 includes a tubular body 551 having a third positioning hole 552 extending axially through the tubular body 551. The lower portion of the tubular body 551 is provided with a fixing portion 553 extending into the first positioning hole 531 or the second positioning hole 532. The fixing portion 553 is fixedly connected to the first positioning hole 531 or the second positioning hole 532, for example, by a threaded connection. When the positioning sleeve 55 is fixed to the corresponding positioning hole, the third positioning hole 552 is coaxially arranged with the corresponding first positioning hole 531 or second positioning hole 532. By changing the aperture of the third positioning hole 552 , arthroscopes 4 or treatment heads 2 of different sizes can be adapted, so that arthroscopes 4 or treatment heads 2 of different sizes can be adapted to the positioning device 5 of the present application through the positioning sleeve 55 .

[0045] In the case of limited medullary cavity space, only one positioning hole may be provided on the positioning piece. Figure 7 , Figure 7 There is only one fourth positioning hole 533 on the positioning member, which runs axially through the positioning member 53. The fourth positioning hole 533 serves as the positioning hole for the arthroscope 4 and the treatment head 2. When the medullary cavity is debridement performed during surgery, the front end of the arthroscope 4 is first inserted into the medullary cavity through the fourth positioning hole 533. At this time, the locking bolt is in a loose state, allowing the positioning member 53 to rotate in the ball socket 513. The rotation of the positioning member 53 in the ball socket 513 allows the arthroscope 4 to capture different positions in the medullary cavity. When it is rotated to the wound site, the locking member 54 is tightened to lock the positioning member 53 in the ball socket 513 so that the positioning member 53 cannot rotate. The arthroscope 4 is removed from the fourth positioning hole 533. After removal, the treatment head 2 of the ultrasonic debridement device is inserted into the medullary cavity through the fourth positioning hole 533 to perform debridement on the wound site. The arthroscope 4 can easily locate the patient's wound site, and the positioning device 5 can locate the wound site, making it easier for the doctor to perform debridement treatment on the wound site through the treatment head 2. The positioning device 5 can reduce the doctor's operating skills and judgment during the treatment process, allowing doctors with less operating experience to achieve good debridement results. It should be understood that the positioning sleeve 55 mentioned above can also be used in the fourth positioning hole 533.

[0046] 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.
