Description

Technical Field

[0001] This utility model relates to the field of ultrasonic probe technology, and in particular to a multifunctional ultrasonic probe structure. Background Technology

[0002] In the medical field, ultrasonic debridement has become a very important treatment method. Ultrasonic debridement uses low-frequency ultrasound to generate a "cavitation effect" in the irrigation jet, which specifically cavitates and breaks down the bacterial biofilm formed in the joint cavity. It generates a shearing force at the solid-liquid interface, removing deep bacteria, viruses and fungi in the joint cavity. By combining surgical debridement with low-frequency ultrasound technology, the clearance rate of wound bacteria and biofilms during surgery can be improved. In traditional revision surgery, after debridement of the medullary cavity, the procedure usually involves rinsing from the surgical area into the medullary cavity, and then using a suction device to aspirate the fluid.

[0003] However, because some infected tissue enters deep into the medullary cavity under the stress of flushing, it can easily lead to residual infected tissue in the deep medullary cavity. Utility Model Content

[0004] This invention provides a multifunctional ultrasound probe structure to solve the problem that infected tissue can easily remain deep in the medullary cavity due to the stress of flushing.

[0012] In the initial state, the limiting airbag inflates and abuts against the probe body, and the blocking airbag contracts and is detachably installed with the probe body;

[0013] During occlusion, the occlusion airbag inflates initially to separate the occlusion airbag from the probe body and fix it to the medullary cavity; then the limiting airbag contracts and pulls the probe body out of the limiting airbag, and then the occlusion airbag inflates a second time to squeeze the limiting airbag, thereby occluding the medullary cavity.

[0014] Furthermore, the limiting mechanism also includes a limiting conduit; the limiting conduit is connected to the limiting airbag; when the limiting airbag inflates, the limiting conduit injects a limiting medium into the limiting airbag; when the limiting airbag contracts, the limiting conduit removes the limiting medium from the limiting airbag.

[0015] Furthermore, the limiting catheter includes a limiting fixation tube and a limiting folding tube; one end of the limiting folding tube is connected to the limiting fixation tube, and the other end is connected to the limiting airbag; in the initial state, the limiting folding tube is rolled up and arranged in the space formed by the occlusion airbag and the probe body; during occlusion, the probe body moves in the medullary cavity to cause the limiting folding tube to unfold.

[0016] Furthermore, the sealing mechanism includes a sealing conduit; the sealing conduit is connected to the sealing airbag; during sealing, the sealing conduit injects a sealing medium into the sealing airbag; when the sealing airbag contracts, the sealing conduit removes the sealing medium from the sealing airbag.

[0019] Furthermore, the probe body includes a constraint ring; the limiting fixing tube, the sealing fixing tube, and the circulating fixing tube are all inserted into the constraint ring.

[0020] Furthermore, the occlusion mechanism also includes a traction belt; one end of the traction belt is connected to the probe body, and the other end is connected to the occlusion airbag; the traction belt is coiled and arranged within the space formed by the occlusion airbag and the probe body; the probe body can use the traction belt to drive the limiting mechanism and the occlusion mechanism to detach from the medullary cavity.

[0021] Furthermore, the lengths of the limiting fold tube, the blocking fold tube, and the circulating fold tube are all less than the length of the traction belt, so that the traction belt restricts the range of movement of the probe body within the medullary cavity.

The blocking mechanism includes a blocking airbag, which is fitted onto the limiting airbag. In the initial state, the limiting airbag inflates and comes into contact with the probe body, while the blocking airbag contracts and is detachably installed with the probe body. During blocking, the blocking airbag inflates initially to separate from the probe body and fix it to the medullary cavity. Then, the limiting airbag contracts and pulls the probe body out of the limiting airbag. Afterward, the blocking airbag inflates a second time to compress the limiting airbag, thereby blocking the medullary cavity.

Detailed Implementation

[0034] Because some infected tissue can penetrate deep into the medullary cavity under the stress of flushing, it can easily lead to residual infected tissue deep in the medullary cavity.

[0035] In view of this, this solution provides a multifunctional ultrasonic probe structure, including a probe body 100, a limiting mechanism 200, and a blocking mechanism 300.

[0036] The following combination Figures 1-5 The structure and shape of the multifunctional ultrasound probe provided in this embodiment are described in detail below:

[0037] The limiting mechanism 200 includes a limiting airbag 210; the limiting airbag 210 is fitted onto the probe body 100; the blocking mechanism 300 includes a blocking airbag 310; the blocking airbag 310 is fitted onto the limiting airbag 210; in the initial state, the limiting airbag 210 expands and abuts against the probe body 100, and the blocking airbag 310 contracts and is detachably installed with the probe body 100; during blocking, the blocking airbag 310 expands initially to separate the blocking airbag 310 from the probe body 100 and fix it to the medullary cavity; then the limiting airbag 210 contracts and pulls the probe body 100 out of the limiting airbag 210, and then the blocking airbag 310 expands a second time to compress the limiting airbag 210, thereby blocking the medullary cavity.

[0038] To enable the detachable installation of the sealing airbag 310 and the probe body 100;

[0039] In the initial state, the blocking airbag 310 contracts and adheres to the probe body 100; during blocking, the blocking airbag 310 expands initially to separate the blocking airbag 310 from the probe body 100.

[0040] In this embodiment, the limiting airbag 210 in the initial state expands and abuts against the probe body 100 to fix the blocking airbag 310 to the probe body 100. At the same time, the blocking airbag 310 is detachably installed on the surface of the probe body 100 to reduce the space required for the multifunctional probe structure to enter the medullary cavity.

[0041] During occlusion, the probe body 100 cleans the occlusion site within the medullary cavity. After cleaning, the occlusion airbag 310 inflates initially to separate the occlusion airbag 310 from the probe body 100 and fix it to the medullary cavity. Then, the limiting airbag 210 contracts and separates from the probe body 100. After the probe body 100 is withdrawn, the occlusion airbag 310 inflates a second time to stack and compress the limiting airbags 210, thereby occluding the medullary cavity. Then, the probe body 100 moves from the bottom of the medullary cavity toward the surgical area and flushes the medullary cavity. The occlusion structure formed by the limiting airbag 210 and the occlusion airbag 310 prevents infected tissue from entering the depths of the medullary cavity.

[0042] When flushing is complete, the occlusion airbag 310 contracts initially, causing the limiting airbag 210 to deploy while remaining fixed to the medullary cavity. Then, the probe body 100 is inserted into the limiting airbag 210. The limiting airbag 210 then expands and comes into contact with the probe body 100. Next, the occlusion airbag 310 contracts a second time to separate from the medullary cavity. After contraction, the occlusion airbag 310 is distributed around the probe body 100. Then, the probe body 100 pulls the occlusion airbag 310 out of the medullary cavity through the limiting airbag 210.

[0043] More details regarding the shape and structure of the limiting mechanism 200:

[0044] The limiting mechanism 200 also includes a limiting conduit 220; the limiting conduit 220 is connected to the limiting airbag 210; when the limiting airbag 210 inflates, the limiting conduit 220 injects a limiting medium into the limiting airbag 210; when the limiting airbag 210 contracts, the limiting conduit 220 removes the limiting medium from the limiting airbag 210.

[0045] To prevent the limiting catheter 220 from moving and being damaged independently within the medullary cavity, the limiting catheter 220 includes a limiting and fixing tube 221 and a limiting and folding tube 222.

[0046] Specifically, the limiting catheter 220 includes a limiting fixation tube 221 and a limiting folding tube 222; one end of the limiting folding tube 222 is connected to the limiting fixation tube 221, and the other end is connected to the limiting airbag 210; in the initial state, the limiting folding tube 222 is rolled up and arranged in the space formed by the occlusion airbag 310 and the probe body 100; during occlusion, the probe body 100 moves in the medullary cavity to make the limiting folding tube 222 unfold.

[0047] In this embodiment, the limiting folding tube 222 is coiled and arranged in the space formed by the blocking airbag 310 and the probe body 100. During the expansion of the blocking airbag 310, it separates from the probe body 100, and then the limiting folding tube 222 unfolds in the medullary cavity. When the probe body 100 moves in the medullary cavity, the limiting fixing tube 221 remains fixed to the medullary cavity, effectively avoiding the probability of displacement and damage of the limiting catheter 220. Then, the limiting catheter 220 extracts the limiting medium from the limiting airbag 210, so that the limiting airbag 210 contracts and separates from the probe body 100. After flushing, the limiting catheter 220 injects the limiting medium into the limiting airbag 210, and the limiting airbag 210 abuts against the probe body 100 through expansion.

[0048] More details regarding the shape and structure of the blocking mechanism 300:

[0049] The sealing mechanism 300 includes a sealing conduit 320; the sealing conduit 320 is connected to the sealing airbag 310; during sealing, the sealing conduit 320 injects sealing medium into the sealing airbag 310; when the sealing airbag 310 contracts, the sealing conduit 320 removes the sealing medium from the sealing airbag 310.

[0050] To reduce the amount of healthy tissue lost during the cleaning process, a temperature control device is also included, and the sealing mechanism 300 also includes a circulation catheter 330.

[0051] Specifically, one end of the circulation conduit 330 is connected to the sealing airbag 310, and the other end is connected to the thermostat; one end of the sealing conduit 320 is connected to the sealing airbag 310, and the other end is connected to the thermostat; the thermostat maintains the sealing medium within a set temperature range; during sealing, the sealing conduit 320 injects the sealing medium from the thermostat into the sealing airbag 310, and the circulation conduit 330 draws the sealing medium from the sealing airbag 310 into the thermostat, so that the sealing medium in the sealing airbag 310 is replaced while maintaining the set pressure.

[0052] To prevent damage to the occlusion catheter 320 and circulation catheter 330 during independent movement within the medullary cavity:

[0053] The occlusion catheter 320 includes an occlusion fixation tube 321 and an occlusion folding tube 322; one end of the occlusion folding tube 322 is connected to the occlusion fixation tube 321, and the other end is connected to the occlusion airbag 310; the circulation catheter 330 includes a circulation fixation tube 331 and a circulation folding tube 332; one end of the circulation folding tube 332 is connected to the circulation fixation tube 331, and the other end is connected to the occlusion airbag 310; in the initial state, both the occlusion folding tube 322 and the circulation folding tube 332 are coiled and arranged in the space formed by the occlusion airbag 310 and the probe body 100; during occlusion, the probe body 100 moves in the medullary cavity to unfold the occlusion folding tube 322 and the circulation folding tube 332.

[0054] In order to remove the limiting mechanism 200 and the blocking mechanism 300 from the medullary cavity in the event of failure of the limiting mechanism 200, the blocking mechanism 300 also includes a traction strap 340.

[0055] Specifically, one end of the traction belt 340 is connected to the probe body 100, and the other end is connected to the occlusion airbag 310; the traction belt 340 is coiled and arranged in the space formed by the occlusion airbag 310 and the probe body 100; the probe body 100 can use the traction belt 340 to drive the limiting mechanism 200 and the occlusion mechanism 300 to detach from the medullary cavity.

[0056] To prevent the limiting folding tube 222, the sealing folding tube 322 and the circulating folding tube 332 from being stretched and damaged during the movement of the probe body 100.

[0057] Specifically, the lengths of the limiting fold tube 222, the blocking fold tube 322, and the circulating fold tube 332 are all less than the length of the traction belt 340, so that the traction belt 340 restricts the range of movement of the probe body 100 within the medullary cavity.

[0058] To improve the ease of inserting the probe body 100 into the limiting airbag 210, a guide groove 311 is provided on the sealing airbag 310.

[0059] Specifically, the guide groove 311 is used to guide the probe body 100 into the limiting airbag 210.

[0060] In this embodiment, the sealing folded tube 322 and the circulating folded tube 332 are both coiled and arranged within the space formed by the sealing airbag 310 and the probe body 100. The sealing medium in the constant temperature device enters the sealing airbag 310 through the sealing conduit 320. The sealing airbag 310 expands for the first time. At this time, the circulating conduit 330 is in a disconnected state, thereby effectively ensuring the stability of the pressure inside the sealing airbag 310, so that the sealing airbag 310 separates from the probe body 100. Then, the sealing folded tube 322 and the circulating folded tube 332 unfold into the medullary cavity. As the probe body 100 moves within the medullary cavity, the sealing folded tube 322 and the circulating folded tube 332 remain fixed to the medullary cavity, effectively avoiding the probability of displacement and damage to the sealing folded tube 322 and the circulating folded tube 332.

[0061] After the probe body 100 is withdrawn from the limiting airbag 210, the sealing medium in the constant temperature device continues to enter the sealing airbag 310 through the sealing conduit 320. The sealing airbag 310 expands twice to make the limiting airbags 210 stack and compress, thereby sealing the medullary cavity. At this time, the circulation conduit 330 draws the sealing medium in the sealing airbag 310 out to the constant temperature device, so that the sealing medium in the sealing airbag 310 is replaced while maintaining the set pressure. Thus, the temperature of the sealing airbag 310 is maintained within the set range, reducing the amount of good tissue in the medullary cavity that is in contact with the sealing airbag 310 and losing temperature.

[0062] When flushing is complete, the occlusion catheter 320 stops supplying the occlusion medium into the occlusion airbag 310. At the same time, the circulation catheter 330 draws the occlusion medium out of the occlusion airbag 310 to the constant temperature device. The occlusion airbag 310 contracts initially, allowing the limiting airbag 210 to unfold while remaining fixed to the medullary cavity. Then, the probe body 100 is inserted into the limiting airbag 210 under the guidance of the guide groove 311. The limiting airbag 210 then expands and comes into contact with the probe body 100. The circulation catheter 330 then continues to draw the occlusion medium out of the occlusion airbag 310 to the constant temperature device. Finally, the occlusion airbag 310 contracts a second time to separate from the medullary cavity.

[0063] When the limiting mechanism 200 malfunctions and cannot be fixed to the probe body 100, the probe body 100 moves out of the medullary cavity, and the probe body 100 drives the limiting airbag 210 and the blocking airbag 310 out of the medullary cavity through the traction belt 340.

[0064] To prevent damage to the limiting fixing tube 221, the sealing fixing tube 321, and the circulation fixing tube 331 during the movement of the probe body 100, the probe body 100 includes a constraint ring 110.

[0065] Specifically, the limiting fixing tube 221, the sealing fixing tube 321, and the circulating fixing tube 331 are all inserted into the constraint ring 110.

[0066] In this embodiment, the limiting fixing tube 221, the blocking fixing tube 321, and the circulating fixing tube 331 are fixed to the probe body 100 by the constraint ring 110. Then, during the movement of the probe body 100, the limiting fixing tube 221, the blocking fixing tube 321, and the circulating fixing tube 331 are moved. During this process, the limiting folding tube 222, the blocking folding tube 322, and the circulating folding tube 332 change their curvature, thereby avoiding damage to the limiting fixing tube 221, the blocking fixing tube 321, and the circulating fixing tube 331 during the movement of the probe body 100.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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. 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.
