Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a multifunctional ultrasonic probe. Background Art

[0002] In the medical field, wound debridement is a key link in promoting wound healing and preventing infection. Traditional debridement methods, such as manually removing necrotic tissue using instruments like scalpels and forceps, are not only relatively cumbersome in operation, but also require high technical skills from doctors, and are prone to damaging surrounding healthy tissues due to improper operation. At the same time, it is difficult to completely remove bacteria and minute contaminants hidden deep in the wound manually.

[0003] With the development of technology, ultrasonic debridement technology has gradually been applied clinically. Ultrasonic debridement utilizes the cavitation effect, mechanical effect, etc. of ultrasonic waves to cause the flushing fluid to generate and rupture minute bubbles, generating a powerful impact force, which can more effectively remove necrotic tissue, bacteria, and foreign bodies in the wound, and reduce damage to healthy tissues. However, existing ultrasonic debridement devices still have some deficiencies. During the debridement process of some ultrasonic probes, the spraying and recovery of the flushing fluid lack a reasonable collaborative design, resulting in uneven distribution of the flushing fluid around the wound, affecting the debridement effect, and the recovery is not timely, which may cause contamination around the wound and increase the risk of infection.

[0033] Embodiment, such as Figures 1-8As shown in the figure, a multi-functional ultrasonic probe includes a probe body 100. An ultrasonic generator 120 is provided at the bottom of the probe body 100. A jet cavity 131 and a recovery cavity 141 are formed inside the probe body 100. The jet cavity 131 is located below the recovery cavity 141. The probe body 100 is provided with a jet hole 130 communicating with the jet cavity 131 and a recovery hole 140 communicating with the recovery cavity 141. The jet hole 130 is used to jet the flushing liquid, and the recovery hole 140 is used to recover the flushing liquid. A retaining cylinder 360 is sleeved on the probe body 100. When the retaining cylinder 360 moves upward, the recovery hole 140 is opened to recover the flushing liquid.

[0034] The working mechanism of the ultrasonic probe provided in this embodiment:

[0035] When performing debridement, the end of the probe body 100 is oriented towards the wound position. The wire 121 of the ultrasonic generator 120 is connected to an external device, and the ultrasonic generator 120 is controlled to operate. At the same time, the external device supplies the flushing liquid into the jet cavity 131, and the flushing liquid then rushes towards the wound position through the jet hole 130. The ultrasonic generator 120 applies ultrasonic vibration to the flushing liquid jetted to the wound, so that the wound is cleaned. After the flushing liquid in the wound increases, the retaining cylinder 360 moves upward, so that the recovery hole 140 is opened, and the height of the recovery hole 140 is higher than that of the jet hole 130, thereby ensuring that the flushing liquid participating in the flushing can be recovered;

[0036] When cleaning the surface wound, a cylindrical protective device is buckled around the wound so that the flushing liquid will not flow everywhere;

[0037] In the initial stage of debridement, the pulse frequency of the jet hole 130 is reduced, and at the same time, the ultrasonic vibration frequency of the ultrasonic generator 120 is relatively low. In the initial debridement of the wound, there may be more contaminants such as dirt, necrotic tissue, and bacteria. Therefore, the lower pulse frequency helps to gently loosen and wash away the large foreign bodies in the wound first. In the middle stage of debridement, after most of the surface dirt and loose necrotic tissue are removed, the pulse and ultrasonic vibration frequencies are increased, so that the cleaning liquid can better penetrate into the gaps and tissues inside the wound to remove the bacteria hidden deep inside and the remaining necrotic tissue fragments. In the late stage of debridement, the pulse frequency and ultrasonic vibration frequency are reduced again. The lower frequency can reduce the stimulation to the already cleaned wound tissue.

[0038] Regarding the structure of the pulse mechanism 200, specifically:

[0039] The injection chamber 131 is communicated with a liquid supply pipe 132, and a pulse mechanism 200 is connected to the liquid supply pipe 132. The pulse mechanism 200 includes a cylinder 210. A cavity 220 is formed in the cylinder 210. The liquid supply pipe 132 is communicated with the cavity 220. A plurality of cylindrical cavities 230 are formed in the cylinder 210. A piston rod 231 is slidably connected to each of the plurality of cylindrical cavities 230. A spring 232 is connected between the piston rod 231 and the bottom wall of the cylindrical cavity 230. An extraction pipe 250 and a discharge pipe 240 are communicated with the cylindrical cavity 230. The discharge pipe 240 is communicated with the cavity 220. The extraction pipe 250 is connected to an external flushing liquid supply. One-way valves are provided on both the extraction pipe 250 and the discharge pipe 240.

[0040] The plurality of piston rods 231 slide into the corresponding cylindrical cavities 230 in turn, so that the flushing liquid in the cylindrical cavity 230 is squeezed and discharged into the cavity 220. The flushing liquid in the cavity 220 then enters the injection chamber 131 through the liquid supply pipe 132 and is then ejected through the injection holes 130. Since the plurality of cylindrical cavities 230 discharge the flushing liquid in turn, the flushing liquid can be discharged through the injection holes 130 in the form of pulses. If it is necessary to increase the pulse force of the injection holes 130, a pressure valve can be further provided in the injection holes 130 to enhance the pulse force. When the sliding speed of the piston rod 231 and the sliding interval time of the plurality of piston rods 231 are reduced, the pulse frequency of the injection holes 130 increases.

[0041] In an alternative embodiment of the present example, preferably:

[0042] The pulse mechanism 200 further includes a double-shaft motor 260. The output end of the double-shaft motor 260 is connected to a drive shaft 261. The output end of the drive shaft 261 is connected to an inclined disk 262. The lower surface of the inclined disk 262 contacts the tops of the plurality of piston rods 231. The inclined disk 262 rotates around the drive shaft 261. When the inclined disk 262 rotates, it presses the plurality of piston rods 231 downward in turn.

[0043] In the initial stage of debridement, the rotation speed of the double-shaft motor 260 is relatively low. At this time, the rotation speed of the inclined disk 262 decreases, so that the inclined disk 262 presses the plurality of piston rods 231 in turn, causing the piston rods 231 to slide into the cylindrical cavities 230. When the rotation speed of the inclined disk 262 increases, the time interval for pressing the plurality of piston rods 231 downward in turn decreases, so that the pulse frequency of the injection holes 130 increases.

[0044] Regarding the structure of the recovery mechanism 300, specifically:

[0045] The recovery mechanism 300 includes an impeller pump 310 connected to the drive shaft 261. A recovery chamber 141 is communicated with a recovery pipe 142. The recovery pipe 142 is connected to the impeller pump 310. When the impeller pump 310 operates, the retaining cylinder 360 moves upward.

[0046] When entering the middle stage of debridement, the rotation speed of the biaxial motor 260 increases. When the rotation speed of the biaxial motor 260 increases, it can drive the impeller pump 310 to operate. When the impeller pump 310 operates, the retaining cylinder 360 moves upward, so that the recovery hole 140 is no longer blocked, and thus the impeller pump 310 can draw back the flushing liquid after participating in the flushing through the recovery hole 140, the recovery chamber 141 and the recovery pipe 142.

[0047] In an alternative embodiment of the present embodiment, preferably:

[0048] The recovery mechanism 300 further includes an air extraction pipe 330. The top of the retaining cylinder 360 is connected with a sliding rod 350. A sliding hole 340 matching with the sliding rod 350 is formed on the probe body 100. The air extraction pipe 330 is communicated with the recovery pipe 142 and the sliding hole 340. When the impeller pump 310 operates, negative pressure is generated in the sliding hole 340, so that the sliding rod 350 moves upward in the sliding hole 340, and thus the recovery hole 140 is opened.

[0049] In the initial state, the retaining cylinder 360 forms a block for the recovery hole 140, so that negative pressure is generated inside the recovery pipe 142 at the initial stage of the operation of the impeller pump 310. This negative pressure is conducted to the sliding hole 340 through the air extraction pipe 330, so that the sliding rod 350 is adsorbed by negative pressure and moves upward. The sliding rod 350 drives the retaining cylinder 360 to move upward, so that the recovery hole 140 is opened.

[0050] In an alternative embodiment of the present embodiment, preferably:

[0051] A magnetic ring is connected to the top of the sliding hole 340, and the sliding rod 350 can be magnetically attracted to the magnetic ring when moving upward.

[0052] When the sliding rod 350 moves upward, the distance between the top end of the sliding rod 350 and the magnetic ring at the top of the sliding hole 340 gradually decreases. When the recovery hole 140 is opened, the top of the sliding rod 350 is within the magnetic attraction range of the magnetic ring. Thus, the magnetic attraction force enables the sliding rod 350 to continue to move upward and maintain the moved state, so that the recovery hole 140 maintains the opened state.

[0053] Regarding the structure of the driving mechanism 400, specifically:

[0054] The driving mechanism 400 includes a driving rod 430 that slides coaxially on the driving shaft 261. The bottom end of the driving rod 430 is connected with a conical ring 432. A through hole matching with the driving shaft 261 is formed in the middle of the pump shaft 320 of the impeller pump 310. A conical groove 322 is arranged in the through hole. When the rotation speed of the driving shaft 261 increases, the conical ring 432 moves upward and abuts against the conical groove 322, so that the driving shaft 261 drives the impeller pump 310 to operate.

[0055] The bottom end of the driving rod 430 is connected to the inner wall of the conical ring 432 through four rectangular bars. A chute matching with the four rectangular bars is formed on the driving shaft 261. When the rotation speed of the driving shaft 261 increases, the driving rod 430 moves upward. At this time, the driving rod 430 drives the conical ring 432 to move upward. At this time, the conical ring 432 can abut against the inner wall of the conical groove 322, so that the driving shaft 261 can drive the pump shaft 320 to rotate through the conical ring 432, and the pump impeller 321 connected to the pump shaft 320 rotates. At this time, the impeller pump 310 operates to extract the flushing liquid.

[0056] In an optional manner of this embodiment, preferably:

[0057] The driving mechanism 400 further includes a fixing frame 410 arranged on the double-shaft motor 260. A small generator 420 is connected to the fixing frame 410. The rotor of the small generator 420 is connected to the driving shaft 261. An electromagnetic coil 470 driven by the small generator 420 is arranged on the fixing frame 410. The driving rod 430 is located in the middle of the electromagnetic coil 470. When the rotation speed of the double-shaft motor 260 increases, the magnetic force of the electromagnetic coil 470 increases, so that the driving rod 430 moves upward.

[0058] The small generator 420 is connected to the other end of the driving shaft 261 of the double-shaft motor 260. When the rotation speed of the double-shaft motor 260 increases, the power generation of the small generator 420 increases. At this time, the power supplied to the electromagnetic coil 470 increases, so that the magnetic force of the electromagnetic coil 470 increases, causing the driving rod 430 to be driven upward. The principle that the electromagnetic coil 470 drives the driving rod 430 to move upward is the same as the operating principle of the solenoid valve stem.

[0059] In an optional manner of this embodiment, preferably:

[0060] A tension spring 433 is connected between the bottom end of the conical ring 432 and the pump shaft 320.

[0061] The tension spring 433 provides resistance to the upward movement of the driving rod 430. Due to the action of the tension spring 433 and the gravity of the driving rod 430, when the rotation speed of the double-shaft motor 260 is relatively low, the magnetic force of the electromagnetic coil 470 will not drive the driving rod 430 to move upward.

[0062] In an optional manner of this embodiment, preferably:

[0063] The top end of the driving rod 430 is coaxially connected with a thin rod 431. The top end of the thin rod 431 is connected with a round plate 450. A clamping ball 440 is connected to the middle of the round plate 450. A clamping groove 411 matching with the clamping ball 440 is formed on the fixing frame 410. A backing plate 460 is placed at the bottom of the round plate 450.

[0064] The circular plate 450 is made of ferromagnetic material. After the circular plate 450 continues to move upward, the clamping ball 440 on the circular plate 450 can be clamped in the clamping groove 411. At this time, the conical ring 432 and the conical groove 322 are in a butting state, so that the driving rod 430 will not move downward subsequently. Thus, when the rotational speed of the biaxial motor 260 decreases, the impeller pump 310 can maintain its operating state;

[0065] The backing plate 460 is C-shaped and is clamped on the thin rod 431, so that the initial distance between the conical ring 432 and the conical groove 322 is adjusted, thus facilitating the later correction of the displacement of the driving rod 430.

[0066] Anti-slip lines are provided at the contact part between the conical ring 432 and the conical groove 322 to ensure synchronous rotation. The column body 210 and the biaxial motor 260 are connected to each other through the base 270. The column body 210, the biaxial motor 260, the small generator 420 and the fixing frame 410 are all arranged in the protective cylinder 110. The protective cylinder 110 protects the components inside it, and a lid that can be opened is provided at the upper part of the protective cylinder 110 to facilitate the increase or decrease of the number of backing plates 460.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
