Description

Technical Field

[0001] The invention relates to the field of osteomyelitis cleaning equipment, in particular to an ultrasonic intracavitary knife device and a cleaning method for cleaning osteomyelitis lesions. Background Art

[0002] At present, the clinical treatment of osteomyelitis lesions mainly involves drainage and flushing of the lesions for debridement. Since the biofilm secreted by the bacteria wraps up the bacteria themselves, it protects the bacteria themselves. As a result, the bacteria increase their immune attack on their own body and tolerance to antibiotics. Moreover, the biofilm is often adsorbed in the bone marrow cavity, especially in the cancellous bone, alternating with the trabeculae. Conventional flushing cannot effectively remove the biofilm, nor can it completely remove the necrotic tissue and bacteria in the lesions. This leads to poor clinical treatment, prolonged course of disease, and huge losses to individuals and society. Summary of the invention

[0003] The object of the present invention is to provide an ultrasonic intracavitary knife device and a cleaning method for cleaning osteomyelitis lesions, which can improve the cleaning effect of osteomyelitis lesions.

[0004] In order to solve the above technical problems, the present invention provides an ultrasonic intracavitary knife device for cleaning osteomyelitis lesions, including a handle and an ultrasonic head detachably connected to one end of the handle, the ultrasonic head is provided with a flushing outlet and a suction inlet, and the handle is equipped with an ultrasonic transducer connected to the ultrasonic head. When the ultrasonic transducer receives an ultrasonic signal, the ultrasonic head generates ultrasonic oscillations through the ultrasonic transducer.

[0005] Furthermore, a catheter is inserted into the ultrasonic transducer, and an end of the catheter is connected to the ultrasonic head.

[0006] Furthermore, a positive pressure input tube and a negative pressure suction tube are provided inside the catheter. When the end of the catheter is connected to the ultrasonic head, the positive pressure input tube is correspondingly connected to the flushing outlet, and the negative pressure suction tube is correspondingly connected to the suction inlet.

[0007] Furthermore, one end of the ultrasonic head away from the handle has an arc-shaped structure, and the suction inlet is arranged inside the arc-shaped structure.

[0008] Furthermore, an end of the ultrasonic head away from the handle has an embedding groove, and the brush sleeve is arranged in the embedding groove.

[0009] Furthermore, the brush is made of flexible material.

[0010] Furthermore, a buffer is provided between the ultrasonic transducer and the handle, and between the ultrasonic head and the handle.

[0011] Furthermore, it also includes a host, which has an ultrasonic generator built in it, and the ultrasonic transducer is connected to the ultrasonic generator through a wiring harness.

[0012] Furthermore, a display area and adjustment buttons are provided on the host.

[0013] The present invention also discloses a method for cleaning osteomyelitis lesions, which adopts an ultrasonic intracavitary knife device and includes the following steps: after the ultrasonic head of the ultrasonic intracavitary knife device is extended into the lesion site, a flushing outlet infuses a constant temperature liquid into the lesion site, and ultrasonic oscillations are generated to the liquid inside the lesion site through the ultrasonic head; when the ultrasonic oscillation continues for a period of time, the ultrasonic oscillation is paused and the liquid inside the lesion site is extracted through a suction inlet.

[0014] The present invention provides an ultrasonic head. When it is necessary to perform debridement treatment on the osteomyelitis lesion, the ultrasonic head is inserted into the lesion and liquid is transported to the inside of the lesion through the liquid flushing outlet. Then, the ultrasonic transducer is started so that the ultrasonic transducer generates ultrasonic waves after receiving the ultrasonic signal and transmits the ultrasonic waves to the ultrasonic head. Then, the ultrasonic head is reciprocated in the liquid to generate cavitation, so that a large number of micron-level vacuum bubbles are formed in the liquid. The bubbles are suddenly closed under the oscillation pressure, so that the bubbles collide with each other during the closing process to generate shock waves. Then, impurities and bacterial biofilms on the surface of the lesion are removed by a large number of shock waves. The inside of the lesion is fully cleaned with continuous ultrasonic oscillation. When the cleaning is completed, the liquid flushing outlet is stopped and the suction inlet is opened. The liquid containing bacteria and impurities in the lesion is sucked out through the suction inlet. The ultrasonic oscillation, flushing, brushing and suction can be repeated to ensure that the lesion is sufficiently cleaned and the cleaning effect of the osteomyelitis lesion is increased.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0020] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0021] like Figure 1-3 The present invention provides an ultrasonic intracavitary knife device for cleaning osteomyelitis lesions, comprising a handle 1 and an ultrasonic head 2 detachably connected to one end of the handle 1, the ultrasonic head 2 being provided with a flushing outlet 21 and a suction inlet 22, the handle 1 being provided with an ultrasonic transducer 11 connected to the ultrasonic head 2, and when the ultrasonic transducer 11 receives an ultrasonic signal, the ultrasonic head 2 generates ultrasonic oscillations through the ultrasonic transducer 11.

[0022] Through the setting of the ultrasonic head, when it is necessary to perform debridement treatment on the osteomyelitis lesion, the ultrasonic head is inserted into the lesion and liquid is transported to the inside of the lesion through the flushing outlet, and then the ultrasonic transducer is started, so that the ultrasonic transducer generates ultrasonic waves after receiving the ultrasonic signal, and transmits the ultrasonic waves to the ultrasonic head, so that the ultrasonic head reciprocates in the liquid to generate cavitation, so that a large number of micron-level vacuum bubbles are formed in the liquid, and the bubbles are suddenly closed under the oscillation pressure, so that the bubbles collide with each other during the closing process to generate shock waves, and then a large number of shock waves are used to cause the impurities and bacterial biofilms on the internal surface of the lesion to fall off, and the inside of the lesion is fully cleaned with continuous ultrasonic oscillation. When the cleaning is completed, the flushing outlet is stopped and the suction inlet is opened, and the liquid containing bacteria and impurities in the lesion is sucked out through the suction inlet. The ultrasonic oscillation, flushing, brushing and suction can be repeated to ensure that the lesion is sufficiently clean and increase the cleaning effect of the osteomyelitis lesion.

[0023] It is worth mentioning that this scheme is suitable for ultrasonic cleaning in various cavities, which specifically refer to the bone marrow cavity, joint cavity, and synovial bursa cavity; among them, in the bone marrow cavity, it is used to remove residual biofilms caused by osteomyelitis and loosening of prosthesis infection; in the joint cavity, it is used to remove osteophytes, and at the same time, ultrasound is used to destroy sensory nerve endings and receptors in the soft tissue near the cartilage, thereby achieving a denervation effect and achieving local loss of pain sensation. In addition, in cases where a large amount of calcium crystals are attached to the tendons and synovial layer on the inner surface of the joint capsule in gouty arthritis, conventional cleaning methods cannot be used to completely remove them, so this scheme is used. Under the impact of ultrasonic oscillation, it is easier to remove calcium crystals from soft tissues; in the synovial bursa cavity, the tendon is wrapped in a synovial bursa at its attachment to the bone. Under the influence of multiple factors such as changes in the mechanical environment, release of inflammatory factors, and hematoma, osteophytes, commonly known as bone spurs, are generated. The ultrasonic head provided in this solution can be operated in the synovial bursa cavity, and the bone and tendon can be separated as much as possible without damaging the tendon in the synovial bursa, thereby maintaining the integrity of the tendon and restoring its normal elastic modulus. In addition, the ultrasonic head can avoid the possibility of bleeding caused by conventional surgical removal of osteophytes, and the release of inflammatory factors that may induce the formation of osteophytes again.

[0024] Preferably, a catheter 12 is inserted into the ultrasonic transducer 11 , and an end of the catheter 12 is connected to the ultrasonic head 2 .

[0025] Specifically, when the ultrasonic transducer receives an ultrasonic signal and converts it into an ultrasonic output, since the catheter is inserted inside the ultrasonic transducer, the ultrasonic wave can be transmitted through the catheter, so that the ultrasonic head connected to the end of the catheter receives the ultrasonic wave through the catheter, and then the ultrasonic head forms an ultrasonic oscillation, thereby increasing the ultrasonic transmission stability between the ultrasonic transducer and the ultrasonic head.

[0026] Preferably, a positive pressure input tube 13 and a negative pressure suction tube 14 are provided inside the catheter 12 . When the end of the catheter 12 is connected to the ultrasonic head 2 , the positive pressure input tube 13 is correspondingly connected to the flushing outlet 21 , and the negative pressure suction tube 14 is correspondingly connected to the suction inlet 22 .

[0027] Specifically, one end of the positive pressure input tube is connected to an external infusion device. When the lesion site needs to be flushed through the flushing outlet, the infusion device is started to input the liquid along the positive pressure input tube, so that the flushing outlet outputs the liquid; the negative pressure suction tube is connected to an external negative pressure device. When the liquid inside the lesion site needs to be sucked out through the suction inlet, the negative pressure device is started to generate negative pressure attraction, so that the liquid inside the lesion site enters from the suction inlet and is output to the negative pressure device along the negative pressure suction tube, so as to ensure the cleaning effect inside the lesion site.

[0028] In particular, since the present solution adopts the method of setting a positive pressure input tube and a negative pressure suction tube through the inside of the catheter, the catheter, the positive pressure input tube and the negative pressure suction tube occupy the same space position in the handle, which greatly reduces the space occupied by the three, so that the handle does not need to be made larger, thereby reducing the production cost and improving the comfort of the user when holding it.

[0029] In this scheme, the external infusion equipment includes a pulse device, which is used to treat the liquid to be infused at a constant temperature so that the constant temperature body fluid enters the lesion site to improve the cleaning effect. At the same time, the liquid to be infused can be a liquid containing medicine or an ordinary water source. It is worth mentioning that the pulse device used in this scheme to transport the liquid to be infused can also ensure that the liquid flushing pressure has no adverse reaction to the normal trabecular structure and bone cells.

[0030] In a preferred embodiment of the present solution, the catheter is made of metal material, and the characteristics of the metal material can effectively transmit ultrasound to ensure the transmission efficiency of ultrasound.

[0031] The ultrasonic head 2 of this solution is provided with a thread groove on the outside, and the setting of the thread groove can increase the contact area between the ultrasonic head 2 and the liquid at the lesion site, thereby improving the oscillation effect. Figure 2 As shown, the diameter of the positive pressure input tube 13 is uniform to facilitate the stable input of liquid; the channel connecting the ultrasonic head 2 and the positive pressure input tube 13 is designed to gradually reduce the diameter from the position close to the positive pressure input tube 13 to the position far away from the positive pressure input tube 13, so that the liquid gathers toward the flushing outlet in the ultrasonic head 2, thereby increasing the infusion speed of the flushing outlet and enhancing the flushing effect.

[0032] Preferably, one end of the ultrasonic head 2 away from the handle 1 has an arc-shaped structure, and the suction inlet 22 is disposed inside the arc-shaped structure.

[0033] Specifically, when aspirating the inside of the lesion through the suction inlet, the straight-tube head cannot completely aspirate the inside of the lesion due to the grooves, curved positions, etc. that may exist inside the lesion. At this time, the arc structure of the present solution allows the curved part of the arc structure to penetrate deep into the grooves, curved positions, etc., making the aspiration process simpler and more complete.

[0034] In particular, the end of the ultrasonic head away from the handle is thinner than the end close to the handle, so that the ultrasonic head can more easily penetrate into the narrow part of the medullary cavity.

[0035] Preferably, one end of the ultrasonic head 2 away from the handle 1 has an embedding groove, and the brush 23 is sleeved in the embedding groove.

[0036] Specifically, when the ultrasonic head generates ultrasonic oscillations, the brush can be placed in the groove so that the brush can oscillate along with the ultrasonic head, and then the inside of the lesion can be scrubbed by the brush to increase the cleaning level during the flushing process. Moreover, since the brush and the groove are detachable, the use of the brush can be adjusted according to the specific usage steps to improve the adaptability of the treatment process of different lesions.

[0037] Preferably, the brush 23 is made of flexible material.

[0038] Specifically, when ultrasonic oscillation brushing is performed by using a brush in conjunction with an ultrasonic head, the brush can effectively avoid damaging normal bone tissue due to its own flexibility.

[0039] In one embodiment of the present solution, the brush body is made of silicone material and has a plurality of convex portions on the outside of the body. During the oscillation of the brush, impurities inside the lesion site are cleaned through the convex portions.

[0040] In another embodiment of the present solution, a plurality of bristles are provided on the outer side of the brush body, the length of the bristles is 2 mm-5 mm, the diameter of a single bristle is 0.05 mm-1.5 mm, and both the brush body and the bristles are made of silicone material.

[0041] In one embodiment of the present scheme, the ultrasonic head may also be provided with a plurality of suction inlets 22 at the same time, so that when one of the suction inlets is blocked, the pumping step can be continued through the remaining suction inlets, thereby avoiding the device being unusable due to blockage of a single suction hole.

[0042] Preferably, a buffer 3 is provided between the ultrasonic transducer 11 and the handle 1 , and between the ultrasonic head 2 and the handle 1 .

[0043] Specifically, when the ultrasonic transducer generates ultrasonic waves and the ultrasonic head generates ultrasonic oscillations, the ultrasonic transducer and the ultrasonic head are damped by the buffer component so that the handle shell will not be subjected to a large vibration, thereby preventing the user from being unable to hold the handle stably due to the large vibration. As a result, the handle can be held stably during use, thereby increasing the accuracy of cleaning the lesion site.

[0044] In the embodiment of the present solution, the buffer member is a silicone ring, which uses the elasticity of the silicone itself to buffer and reduce shock to the ultrasonic transducer and the ultrasonic head.

[0045] After receiving the high-frequency ultrasonic signal, the ultrasonic transducer provided in this solution outputs ultrasonic waves to the front end of the ultrasonic head. When the sound waves encounter the liquid, they can cause it to oscillate, which can separate the biofilm in the lesion from the trabeculae or implants, making it easier to be flushed away by the liquid.

[0046] Preferably, the device further comprises a host 4 , in which an ultrasonic generator 41 is built in, and the ultrasonic transducer 11 is connected to the ultrasonic generator 41 via a wiring harness 5 .

[0047] Specifically, when ultrasonic oscillation cleaning is required through the ultrasonic head camera, the ultrasonic generator inside the host is started, and then an ultrasonic signal is generated by the ultrasonic generator. The ultrasonic signal is then transmitted along the wiring harness to the ultrasonic transducer, thereby causing the ultrasonic transducer to generate ultrasonic waves.

[0048] Preferably, a display area 42 and adjustment buttons 43 are provided on the host 4 .

[0049] Specifically, the ultrasonic signal, ultrasonic wave size and other information are displayed in the display area, and the user controls the ultrasonic signal output size of the ultrasonic generator by rotating or pressing the adjustment button, thereby controlling the ultrasonic oscillation frequency of the ultrasonic head.

[0050] Preferably, a fill light 15 and a camera 16 are connected to one end of the handle 1 close to the ultrasonic head 2 .

[0051] Specifically, in order to better observe the intracavitary biofilm, osteophytes, calcium crystals, cartilage-soft tissue interface, removal and destruction, the device is equipped with a light source and an endoscope device. When using the ultrasonic head to clean the lesion, the fill light is turned on to illuminate the lesion so that the deep part of the lesion can be clearly seen. At the same time, through the setting of the camera, not only can case analysis be performed through the display device connected to the camera when using the ultrasonic head, but the lesion can also be photographed and recorded through the camera for subsequent observation.

[0052] The present invention also discloses a method for cleaning osteomyelitis lesions, which adopts an ultrasonic intracavitary knife device and includes the following steps: after the ultrasonic head of the ultrasonic intracavitary knife device is extended into the lesion site, a flushing outlet infuses a constant temperature liquid into the lesion site, and ultrasonic oscillations are generated to the liquid inside the lesion site through the ultrasonic head; when the ultrasonic oscillation continues for a period of time, the ultrasonic oscillation is paused and the liquid inside the lesion site is extracted through a suction inlet.

[0053] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
