Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ultraviolet light sterilization ultrasonic probe. Background Technology

[0002] During surgery, the ultrasound probe only functions at its distal end, removing necrotic tissue through ultrasonic cavitation and mechanical vibration. However, it cannot directly kill bacteria within the surgical area, thus requiring the use of an external ultraviolet lamp of a specific wavelength for sterilization. However, external ultraviolet lamps have limitations; their sterilization effect is restricted by the irradiation range and penetration power, making it difficult to comprehensively cover and kill all bacteria, especially those that are obscured or located in deep tissues.

[0003] Existing ultrasound probes can only remove necrotic tissue through the ultrasonic cavitation effect and mechanical vibration at the tip, but cannot kill bacteria in the surgical area, thus requiring the use of an external ultraviolet lamp for sterilization. Utility Model Content

[0004] The purpose of this invention is to provide an ultraviolet light sterilization ultrasonic probe to solve the technical problem in related technologies that can only remove necrotic tissue through the ultrasonic cavitation effect and mechanical vibration of the end head, but cannot kill bacteria in the surgical area, thus requiring the use of an external ultraviolet light source to achieve sterilization.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] The ultraviolet light sterilization ultrasonic probe provided by this utility model includes:

[0007] The probe body comprises a working rod, a handle, and a transducer. The working rod is inserted into the handle, and the transducer is mounted on the working rod to generate periodic vibrations. The sterilization component includes an ultraviolet lamp, which is fitted around the outer periphery of the working rod to generate ultraviolet light to kill bacteria in the surgical area.

[0008] Specifically, the sterilization component also includes a light-shielding filter cover, which is fitted onto the ultraviolet lamp to block and filter ultraviolet light other than the 222nm wavelength.

[0009] Specifically, it also includes a waterproof component, which comprises a first waterproof unit and a second waterproof unit. The first waterproof unit and the second waterproof unit are sleeved on the working rod and respectively disposed at both ends of the filter shield to seal the tube gap formed between the filter shield and the working rod.

[0010] Specifically, the first waterproof unit includes a first sealing ring and a first compression cap. The first sealing ring is sleeved on the working rod, and the first compression cap is threaded to the working rod and applies a pushing force to the first sealing ring so that the first sealing ring abuts against the light filter shield and seals the opening of the sleeve gap away from the handle.

[0011] Specifically, the second waterproof unit includes a second sealing ring and a second compression cap. The second sealing ring is sleeved on the working rod, and the second compression cap is threaded to the working rod and applies a pushing force to the second sealing ring so that the second sealing ring abuts against the light filter shield and seals the opening of the sleeve near the handle end.

[0012] Specifically, the probe body also includes a drainage tube. The working rod includes an amplitude transformer and a debridement blade, and the debridement blade, the amplitude transformer, and the transducer are all configured as hollow tubes. The debridement blade, the amplitude transformer, the transducer, and the drainage tube are sequentially connected to form a debridement pathway. The cleaning solution is discharged from the debridement blade through the debridement pathway.

[0013] Specifically, the probe body further includes a waste liquid recovery tube, and the working rod further includes a waste liquid recovery protective shell. The waste liquid recovery protective shell is fitted onto the debridement blade, and the waste liquid recovery tube is connected to the waste liquid recovery protective shell. One end of the annular channel formed between the debridement blade and the waste liquid recovery protective shell is open through a waste liquid inlet, and the other end is connected to a negative pressure generating device through the waste liquid recovery tube to form a waste liquid recovery path. The negative pressure generating device is used to generate negative pressure in the waste liquid recovery path so that the waste liquid enters the waste liquid recovery path through the waste liquid inlet under negative pressure to complete the recovery. The flowing waste liquid can carry away the waste heat of the ultraviolet lamp, preventing the ultraviolet lamp from being damaged due to heat accumulation.

[0014] Specifically, the transducer includes a piezoelectric ceramic, a heat sink, and fastening bolts. The fastening bolts are sequentially inserted into the heat sink and the piezoelectric ceramic, and threadedly connected to the amplitude transformer. Each fastening bolt has a central channel, with its two ends connected to the amplitude transformer and the drain pipe, respectively. The piezoelectric ceramic has conductive electrodes; when energized through these electrodes, the piezoelectric ceramic can generate periodic vibrations.

[0015] Specifically, the probe body also includes a vibration isolation block, which is sleeved on the working rod and inserted into the handle. The vibration isolation block is made of elastic material to prevent the vibration of the transducer from being transmitted to the handle through the working rod.

[0016] Specifically, the ultraviolet lamp is set to a 222nm excimer lamp.

[0017] Based on the above technical solutions, the beneficial effects of this utility model are analyzed as follows:

[0018] This utility model provides an ultraviolet light sterilization ultrasonic probe, comprising:

[0019] The probe body comprises a working rod, a handle, and a transducer. The working rod is inserted into the handle, and the transducer is mounted on the working rod to generate periodic vibrations. The sterilization component includes an ultraviolet lamp, which is fitted around the outer periphery of the working rod to generate ultraviolet light to kill bacteria in the surgical area.

[0020] In practical applications, when this ultraviolet (UV) sterilization ultrasonic probe performs wound debridement, the periodic vibrations generated by the transducer remove necrotic tissue through ultrasonic cavitation and mechanical vibration at the end of the working rod. Simultaneously, because the UV lamp is mounted on the working rod, it moves synchronously with the rod and releases UV light along the debridement path of the UV sterilization ultrasonic probe, providing a synergistic sterilization effect. As debridement progresses, the area of ​​pathogen elimination gradually expands and radiates to various parts of the body, achieving a more comprehensive sterilization effect.

[0021] As can be seen, compared with existing technologies, this ultraviolet light sterilization ultrasonic probe, by mounting the ultraviolet lamp on the working rod, uses ultraviolet light emitted by the lamp to kill bacteria in the surgical area, achieving a synergistic sterilization effect while cleaning the wound. This overcomes the technical problem of existing ultrasonic probes, which can only remove necrotic tissue through the ultrasonic cavitation effect and mechanical vibration of the tip, but cannot kill bacteria in the surgical area, thus requiring the use of an external ultraviolet light source for sterilization.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Existing ultrasound probes can only remove necrotic tissue through the ultrasonic cavitation effect and mechanical vibration at the tip, but cannot kill bacteria in the surgical area, thus requiring the use of an external ultraviolet lamp for sterilization.

[0038] In view of this, the present invention provides an ultraviolet light sterilization ultrasonic probe, comprising:

[0039] The probe body 100 and the sterilization component 200 are included. The probe body 100 includes a working rod 110, a handle 120, and a transducer 130. The working rod 110 is inserted into the handle 120, and the transducer 130 is mounted on the working rod 110 to generate periodic vibration. The sterilization component 200 includes an ultraviolet lamp 210, which is sleeved on the outer periphery of the working rod 110 to generate ultraviolet light to kill bacteria in the surgical area.

[0040] In summary, the ultraviolet light sterilization ultrasonic probe provided by this utility model can achieve the following technical effects:

[0041] This ultraviolet (UV) sterilization ultrasonic probe mounts a UV lamp 210 on a working rod 110. The UV light emitted by the lamp 210 kills bacteria in the surgical area, achieving a synergistic sterilization effect while cleaning the wound. This overcomes the technical problem of existing ultrasonic probes, which can only remove necrotic tissue through the ultrasonic cavitation effect and mechanical vibration at the tip, but cannot kill bacteria in the surgical area, thus requiring the use of an external UV lamp for sterilization.

[0042] The following combination Figures 1 to 7 The structure and shape of the ultraviolet light sterilization ultrasonic probe provided in this embodiment are described in detail below:

[0043] To prevent the ultraviolet light from the ultraviolet lamp 210 from harming the human eyes, in this embodiment, the sterilization component 200 further includes a filter shield 220. The filter shield 220 is fitted over the ultraviolet lamp 210 to block and filter ultraviolet light except for the 222nm wavelength. Ultraviolet light with a wavelength of 222nm is highly efficient and broad-spectrum in sterilization, rapidly destroying the genetic material of various pathogens and rendering them inactive. In terms of safety, due to its weak penetration, it is harmless to human skin and eyes, enabling sterilization that allows for coexistence between humans and the machine. The filter shield 220 includes a transparent substrate and a filter coating. The filter coating is disposed on the side of the transparent substrate closest to the ultraviolet lamp 210, preventing the filter coating from being directly exposed to the external environment and avoiding damage to the coating due to external factors such as dust, pollution, and physical impacts, thereby ensuring the stability and reliability of the filter coating. The transparent substrate can be made of materials such as quartz glass, magnesium fluoride, or lithium fluoride.

[0044] To prevent the ultraviolet lamp 210 from being damaged by cleaning fluids or bodily fluids, in this embodiment, the ultraviolet sterilization ultrasound probe further includes a waterproof component 300, which includes a first waterproof unit 310 and a second waterproof unit 320. The first waterproof unit 310 and the second waterproof unit 320 are sleeved on the working rod 110 and respectively positioned at both ends of the filter shield 220 to seal the gap between the filter shield 220 and the working rod 110. The working rod 110, the first waterproof unit 310, the filter shield 220, and the second waterproof unit 320 form a sealed annular space around the ultraviolet lamp 210, isolating the ultraviolet lamp 210 from the external environment. This ultraviolet sterilization ultrasound probe can make more thorough contact with the tissue in the surgical area, avoiding insufficient external radiation.

[0045] Regarding the structural composition of the first waterproof unit 310, specifically:

[0046] The first waterproof unit 310 includes a first sealing ring 311 and a first clamping cap 312. The first sealing ring 311 is sleeved on the working rod 110, and the first clamping cap 312 is threaded to the working rod 110 and applies a pushing force to the first sealing ring 311 so that the first sealing ring 311 abuts against the filter shield 220 and seals the opening at the end of the tube sleeve away from the handle 120.

[0047] Regarding the structural composition of the second waterproof unit 320, specifically:

[0048] The second waterproof unit 320 includes a second sealing ring 321 and a second clamping cap 322. The second sealing ring 321 is sleeved on the working rod 110, and the second clamping cap 322 is threaded to the working rod 110 and applies a pushing force to the second sealing ring 321 so that the second sealing ring 321 abuts against the light filter shield 220 and seals the opening near the end of the tube sleeve gap near the handle 120.

[0049] Specifically, regarding how the cleaning solution cleans the wound:

[0050] In this embodiment, the probe body 100 also includes a drainage tube 140. The working rod 110 includes an amplitude transformer 111 and a debridement blade 112, all of which are hollow tube structures. The debridement blade 112, amplitude transformer 111, and transducer 130 are sequentially connected to form a debridement pathway. The cleaning fluid is discharged from the debridement blade 112 through the debridement pathway. It not only serves as a medium for transmitting ultrasound, allowing ultrasound to propagate in the liquid and generate a cavitation effect, thereby dissolving and decomposing dirt, bacteria, etc. on the wound surface, but also assists ultrasound in more effectively removing these substances. At the same time, the presence of the cleaning fluid reduces the direct effect of ultrasound on normal tissue, protecting normal tissue and reducing the risk of damage. In addition, under the action of ultrasound, the cleaning fluid can stimulate the activity of fibroblasts, promote the growth of granulation tissue, and accelerate the wound healing process. The flowing cleaning fluid can also remove the waste heat from the UV lamp 210, preventing the UV lamp 210 from being damaged due to heat accumulation. The heated cleaning fluid further enhances its cleaning effect.

[0051] Specifically, regarding how waste liquid containing wound contaminants is recycled:

[0052] The probe body 100 also includes a waste liquid recovery pipe 150, and the working rod 110 includes a waste liquid recovery protective shell 113. The waste liquid recovery protective shell 113 is fitted onto the debridement blade 112, and the waste liquid recovery pipe 150 is connected to the waste liquid recovery protective shell 113. One end of the annular channel formed between the debridement blade 112 and the waste liquid recovery protective shell 113 is open through the waste liquid inlet 101, and the other end is connected to the negative pressure generating device through the waste liquid recovery pipe 150 to form a waste liquid recovery path. The negative pressure generating device is used to generate negative pressure in the waste liquid recovery path so that the waste liquid enters the waste liquid recovery path through the waste liquid inlet 101 under negative pressure to complete the recovery. The flowing waste liquid can carry away the waste heat of the ultraviolet lamp 210, preventing the ultraviolet lamp 210 from being damaged due to heat accumulation.

[0053] In this embodiment, the transducer 130 includes a piezoelectric ceramic 131, a heat sink 133, and a fastening bolt 132. The fastening bolt 132 is sequentially inserted into the heat sink 133 and the piezoelectric ceramic 131 and threadedly connected to the amplitude transformer 111. The fastening bolt 132 is provided with a central channel, the two ends of which are respectively connected to the amplitude transformer 111 and the drain pipe 140. The piezoelectric ceramic 131 is provided with conductive electrodes, and the piezoelectric ceramic 131 can generate periodic vibration when energized through the conductive electrodes.

[0054] To prevent the vibration of the transducer 130 from being transmitted to the handle 120 and affecting the operator's grip on the ultraviolet sterilization ultrasonic probe, in this embodiment, the probe body 100 further includes a vibration isolation block 160. The vibration isolation block 160 is sleeved on the working rod 110 and inserted into the handle 120. The vibration isolation block 160 is made of an elastic material, and it absorbs the periodic vibration of the transducer 130 through elastic deformation, thereby preventing the vibration of the transducer 130 from being transmitted to the handle 120 through the working rod 110. The vibration isolation block 160 may be made of rubber.

[0055] In order to improve the generation efficiency of 222nm wavelength ultraviolet light that can penetrate the filter shield 220, thereby improving the sterilization efficiency of the sterilization component 200, in this embodiment, the ultraviolet lamp 210 is set as a 222nm excimer lamp.

[0056] In summary, the specific working process of the ultraviolet light sterilization ultrasonic probe provided in this embodiment is as follows:

[0057] When using this UV-sterilizing ultrasonic probe for wound cleaning, the operator holds the handle 120 to bring the cleaning head 112 into contact with the wound. The periodic vibration of the piezoelectric ceramic 131 is transmitted to the cleaning head 112 through the amplitude transformer 111 to apply mechanical vibration to the wound. The cleaning solution is sprayed from the cleaning head 112 onto the wound through the drainage tube 140, transducer 130, and amplitude transformer 111. The periodic vibration of the piezoelectric ceramic 131 generates ultrasonic waves that propagate in the cleaning solution and produce a cavitation effect, thereby dissolving and decomposing dirt, bacteria, etc. on the wound surface. Necrotic tissue is removed through the combined effect of ultrasonic cavitation and mechanical vibration.

[0058] When the ultraviolet lamp 210 is activated, the ultraviolet light generated by it is filtered by the light shield 220, allowing only the 222nm wavelength ultraviolet light to be emitted and irradiate the surgical area tissue. Because 222nm wavelength ultraviolet light is highly effective and broad-spectrum in sterilization, it can rapidly destroy the genetic material of various pathogens and has weak penetration, making it harmless to human skin and eyes, thus enabling sterilization and disinfection that can be performed simultaneously with the machine. At the same time, the flowing cleaning fluid carries away some of the waste heat generated by the ultraviolet lamp 210, preventing damage due to heat buildup. The cleaning fluid also absorbs heat and warms up, further improving the cleaning effect.

[0059] Waste fluid containing wound contaminants such as dirt, bacteria, and necrotic tissue enters the annular channel formed between the debridement head 112 and the waste fluid recovery shell 113 through the waste fluid inlet 101 under negative pressure and is then drawn out along the waste fluid recovery pipe 150. Simultaneously, the flowing waste fluid carries away some of the waste heat generated by the ultraviolet lamp 210, preventing the ultraviolet lamp 210 from being damaged due to heat buildup.

[0060] The ultraviolet lamp 210 provides a synergistic sterilization effect along the cleaning path of the cleaning blade 112. As the cleaning operation continues, the area of ​​sterilization can gradually expand and radiate to various parts of the body, achieving a more comprehensive sterilization effect.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
