Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic endoscope medical instruments, and in particular to an ultrasonic endoscope microprobe water bag. Background Art

[0002] In recent years, with the rapid development of digestive endoscopy, various mucosal and submucosal lesions within the digestive tract have been discovered. Ultrasound endoscopic technology has been widely used to determine the nature, layer, and depth of the lesions, providing a more scientific basis for the formulation of treatment plans. However, due to the air gap between the ultrasound endoscopic instrument and the mucosa, ultrasound waves are poorly transmitted and absorbed in the air, making it impossible to obtain an effective reflected image. Therefore, clean water is required as a medium to obtain a clear image. However, during the diagnosis and treatment process, doctors often encounter difficulties in storing water as a medium, interference from secretions, and intolerance to conventional ultrasound endoscopic examinations, resulting in ineffective examinations and even the risk of suffocation. With the development of ultrasound endoscopic technology, water balloons have been introduced, solving some of the difficulties in ultrasound endoscopic operation and diagnosis. However, some hospitals only have micro-probe ultrasonic endoscope equipment, or certain cases can only be diagnosed and treated with micro-probe ultrasonic endoscope equipment. At present, there is a lack of safe and efficient water bag devices that are compatible with micro-probe ultrasonic endoscopes on the market. Some homemade water bags cover the front end of the endoscope, which will block the camera and affect observation and progress. At the same time, because the camera is covered in the water bag, it is impossible to judge the amount of water injected. During operation, the water bag may explode due to excessive water injection.

[0003] To solve the above problems, the existing technology provides many solutions, such as the following existing technology JP6125130B1. This patent discloses an ultrasonic endoscope and an injection device, in which the ultrasonic endoscope, the insertion body and the main body, the insertion part is arranged at the front end, the front end surrounds the ultrasonic wave, the ultrasonic wave transmitter and receiver are connected to the balloon with a groove, the water supply port of the water nozzle formed in the groove is connected to the rigid part of the balloon, the water supply port and the channel are connected to the water balloon, the balloon is connected to the connector part of the light source device of the ultrasonic endoscope and the operating section and a supply pipeline connected to the universal cable setting. This patent solves the problem of difficult operation when removing the balloon after using the ultrasonic endoscope and the problem of controlling the water volume of the balloon, but there is still room for improvement in effectively judging the water volume and improving the diagnosis and treatment effect and comfort during ultrasonic endoscopic diagnosis and treatment. Summary of the Invention

[0004] The purpose of the present invention is to provide an ultrasonic endoscope microprobe water bag, which can determine the water volume of the water bag during ultrasonic endoscope diagnosis and control it, thereby effectively improving the diagnosis and treatment effect and the patient's diagnosis and treatment comfort.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solutions: an ultrasonic endoscope microprobe water bag, comprising a fixing member, the end of which is detachably connected to the water bag, and the fixing member is provided with at least two first channels that can communicate with the water bag. The fixing member can be detachably connected to the ultrasound probe. During use, the ultrasound probe is inserted into the fixing member and brought into contact with the water bag, achieving adhesion between the water bag and the ultrasound probe, thereby preventing air from entering between the two. Furthermore, a circle of medical film is provided on the contact end surface of the fixing member and the ultrasound probe. When the fixing member and the ultrasound probe are assembled, the inner side of the medical film is removed to maintain the plug-in seal between the ultrasound probe and the fixing member, as well as the seal between the ultrasound probe and the water bag. This prevents air from entering the connection space between the fixing member and the ultrasound probe, or from air existing between the ultrasound probe and the water bag, which could affect the transmission of ultrasound waves during ultrasound endoscopy diagnosis. The water bag is emptied and folded before use. During use, water is introduced through the first channel to fill it. The filling state of the water bag can be determined by recording the amount of water injected into the first channel, and water is then discharged or introduced through the first channel. This makes water storage more efficient, makes ultrasound endoscopy diagnosis and treatment safer for patients, and improves examination efficiency and accuracy. The appropriately sized water bag reduces patient discomfort during diagnosis and treatment, thereby enhancing patient comfort.

[0006] The inner diameter of the water balloon is 2.6mm. Depending on the different ultrasonic endoscopic microprobes, the length of the water balloon can be set to various models such as 15.0mm and 25.0mm. The inner diameter of the water balloon can also be adaptively replaced according to different ultrasonic endoscopic microprobes and is not limited to 2.6mm.

[0007] According to one embodiment of the present invention, at least one first channel is connected to a second pipeline, a pressure sensor can be set inside the water bag, and the second pipeline is used to discharge the water inside the water bag. By recording the input amount to the water bag, the water content inside the water bag can be monitored, and the pressure sensor monitoring can be used to prevent the water bag from bursting. The second pipeline can discharge part of the water for adjustment when the internal pressure of the water bag is too high or the input water volume is excessive. The size of the water bag can also be adjusted through the second pipeline when inserting or removing the water bag during ultrasonic endoscopic diagnosis and treatment, which is convenient for taking and placing the water bag. Of course, the water outlet section of the second pipeline can be connected to a measuring cup or meter to record the discharged water, so that the purpose of precise control can be achieved. The water bag only covers the ultrasonic endoscope microprobe, does not block the endoscope camera, does not affect the entry and observation of the endoscope, and can directly observe the expansion of the water bag during operation, perform appropriate water injection, and reduce the risk of the water bag self-explosion.

[0008] According to one embodiment of the present invention, at least one first channel is connected to a pre-treatment assembly via a first pipeline. The pre-treatment assembly is connected to a water bag assembly via the first pipeline. The water bag assembly includes a water bag, one end of which is connected to a fixing member. The water entering the water bag assembly can affect the results of ultrasound examinations, such as if the water is too cold and the patient cannot tolerate the water bag and cannot cooperate with the ultrasound examination, or if the water contains a large amount of gas that affects ultrasound transmission. Therefore, a pre-treatment assembly is provided to pre-treat the water entering the water bag assembly. Specifically, the pre-treatment assembly controls the temperature of the water bag so that the operating temperature of the water bag is close to the patient's internal body temperature to resolve tolerance issues and reduce the gas content in the water to improve the accuracy of ultrasound examination results.

[0009] According to one embodiment of the present invention, the pre-treatment component includes a first shell, the first shell has a built-in cavity, the cavity runs through the two ends of the first shell, the side of the first shell has a first tube body connected to the cavity, the first tube body is connected to the first pipeline, the medium is sent into the interior of the first shell for treatment and then discharged through the first tube body and the first pipeline, and an electric control valve or valve can be optionally provided on the first pipeline to control the opening or closing of the first pipeline. Of course, an electric control valve or valve can also be provided on the first tube body.

[0010] According to one embodiment of the present invention, one end of the first shell is detachably connected to the second sealing plate, and the other end of the first shell is detachably connected to the first sealing plate. An injection pipeline is provided on the second sealing plate, and the output port of the injection pipeline is provided inside the cavity of the first shell. An exhaust valve is provided on the second sealing plate. The second sealing plate and the first sealing plate are used to seal the two ends of the first shell to prevent leakage of the internal medium. The provided injection pipeline is used to deliver the medium into the first shell. The injection pipeline can be connected to the syringe, and the syringe can accurately measure to achieve the purpose of controlling the size of the water bag. The exhaust valve on the second sealing plate can discharge the gas inside the first shell, thereby solving the problem of more gas in the medium.

[0011] According to one embodiment of the present invention, a second shell is provided inside the first shell. The second shell is a rotating body structure and is provided with a through hole in the middle. One end of the second shell is connected to the second sealing plate, and the diameter of the other end is smaller than the diameter of the end connected to the second sealing plate. Air vents are provided around the surface of the second shell. When the water in the first shell passes through the air vents on the second shell, it helps the gas-liquid separator, promotes the discharge of gas in the water, reduces the gas content in the water, and improves the accuracy of the results of subsequent ultrasonic inspections. The air vents can intercept impurities in the water medium to eliminate the possibility of misdiagnosis caused by the presence of impurities in the water bag. In addition, after the water passes through the air vents on the second shell, it helps to divert and converge the water, which has an improving effect on the uniformity of the water temperature distribution and solves the problem that the uneven temperature of the water medium affects the subsequent delivery into the water bag, resulting in uneven temperature distribution of the water bag.

[0012] According to one embodiment of the present invention, a third shell with an opening at one end is disposed on the first sealing plate. The opening of the third shell is disposed within the cavity of the first shell, and a heating assembly is housed within the third shell. The heating assembly is used to heat the water within the first shell to a suitable temperature, thereby resolving the issue of temperature intolerance caused by the water bladder.

[0013] One end of the second shell is connected to a second sealing plate, which has an annular mounting groove that can be assembled with the end of the second shell. The other end of the second shell is plugged into the opening of the third shell. The second shell port has an annular segment that is inserted into the opening of the third shell to connect the third shell to the second shell. The outlet end of the injection line is located in the second shell. Water introduced by the injection line is discharged downwardly within the second shell and enters the interior of the third shell. After the water is heated by the heating component, the water is discharged from the vent on the second shell for water filtration and gas removal. The amount of water introduced through the injection line must be greater than the capacity of the water bag. Some of the water will remain in the third shell. When calculating the water volume in the water bag, the water volume from the third shell to the lowest water level vent position of the second shell needs to be subtracted. Temporarily storing water in the third shell can not only quickly deliver temperature-controlled water to the next patient, shortening the diagnosis and examination time, but also helps to disperse impurities trapped by the vent to prevent accumulation and blockage of the vent.

[0014] According to one embodiment of the present invention, a heating assembly includes a heating rod having a first ring disposed on an outer side of the heating rod. A second ring is disposed coaxially with the first ring within its inner ring, the first ring being connected to the second ring via a second connecting plate. A fourth ring is disposed coaxially with the second ring within its inner ring, the fourth ring being connected to the second ring via a first connecting plate. The fourth ring is sleeved over the heating rod and, after the two are connected and assembled, the fourth ring cannot move relative to the heating rod. The first connecting plate, the second ring body, the second connecting plate and other components are made of heat-conducting materials. The heating rod is used to heat the water body so that the water temperature is close to the temperature inside the patient's body, solving the problem that the water bag temperature causes the patient to refuse to cooperate with the examination. The first ring body is capable of contacting the inner wall of the third shell, so that the heating rod and the third shell are coaxial. In this way, maintaining the position of the heating rod for entering the water body helps to ensure the heating effect of the water body, and the second ring body, the first connecting plate and other components are used to expand the heat exchange area of the water body and improve the heat exchange efficiency. For impurities trapped and deposited at the bottom of the third shell by the vent, the second ring body, the first connecting plate and other components can relatively reduce their re-suspension probability to ensure the circulation effect of the vent on the second shell.

[0015] According to one embodiment of the present invention, the fixing member is a rotating body structure, with a mounting channel provided in the middle of the fixing member, the mounting channel extending through both ends of the fixing member, and extension rings extending outwardly at the upper and lower ends of the fixing member. The fixing member with a rotating body structure can be preferably placed in the patient's body, the mounting channel is used for mounting with the ultrasonic microprobe, and the extension ring can limit the position of the fastening rubber ring on the outside of the fixing member. After the ultrasonic microprobe is mounted in the mounting channel of the fixing member, the fastening rubber ring can be placed on the outside of the fixing member to apply a tightening force to the fixing member to promote tight contact between the fixing member and the ultrasonic microprobe, and the extension ring can prevent the fastening rubber ring from detaching.

[0016] According to one embodiment of the present invention, the mounting channel of the fixing member is provided with a first concave assembly ring groove, and the water bladder has a convex ring corresponding to the first assembly ring groove. The first assembly ring groove and the convex ring enable the fixing member and the water bladder to be assembled and disassembled, and the connection between the two to be sealed. Water bladders of different lengths can be selectively used, solving the problem of poor adaptability of the integrated structure. In addition, the first assembly ring groove can provide a certain buffer release space when the water bladder is overfilled, reducing the risk of self-explosion due to overfilling. The contact surface between the water bladder and the fixing member is provided with adhesive and medical film. During use, the medical film can be torn off, allowing the adhesive to fill between the water bladder and the fixing member to achieve a seal, prevent the ingress or egress of media, and improve the tightness of the connection between the water bladder and the fixing member. The fixing member and water bladder of the present invention are preferably made of medical polymer materials. The finished fixing member and water bladder are sealed and bagged in a sterile packaging bag. The fixing member and water bladder are disposable medical products, eliminating secondary use.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the fixing part of the present invention can be detachably connected to the ultrasonic probe. When in use, the ultrasonic probe is inserted into the fixing part and contacts the water bag, so that the water bag and the ultrasonic probe are attached to each other to prevent air from entering between the two. The water bag is emptied and folded before use. When in use, water is fed into the first channel to fill it. The filling state of the water bag can be determined by recording the amount of water injected into the first channel, and water can be discharged or fed in through the first channel. This makes the storage of water media more efficient, makes it safer for patients to undergo ultrasonic endoscopic diagnosis and treatment, improves the inspection efficiency and accuracy, and the appropriately sized water bag reduces the patient's discomfort during diagnosis and treatment, thereby improving the patient's diagnosis and treatment comfort.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 without making creative efforts are within the scope of protection of the present invention.

[0027] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] Example 1:

[0029] like Figure 1-5As shown, the present invention provides an ultrasonic endoscope microprobe water bag, including a fixing part 31, the end of the fixing part 31 is detachably connected to the water bag 32, and the fixing part 31 is provided with at least two first channels that can communicate with the water bag 32. The fixing part 31 can be detachably connected to the ultrasonic probe. When in use, the ultrasonic probe is inserted into the fixing part 31 and is in contact with the water bag 32, so that the water bag 32 and the ultrasonic probe are attached to each other to prevent air from entering between the two. Furthermore, a circle of medical film is provided on the end surface of the fixing part 31 in contact with the ultrasonic probe. When the fixing part 31 and the ultrasonic probe are assembled, the inner film of the medical film is torn off to maintain the plug-in sealing state of the ultrasonic probe and the fixing part 31 and the sealing state of the ultrasonic probe and the water bag 32, so as to prevent air from entering the fixing part 31 and the ultrasonic probe during the ultrasonic endoscope diagnosis process. The head connection space and the air between the ultrasound probe and the water bag 32 affect the transmission of ultrasound waves. The water bag 32 is emptied and folded before use. When in use, water is introduced into the water bag through the first channel to fill it. The filling state of the water bag 32 can be determined by recording the amount of water injected into the first channel, and water can be discharged or introduced through the first channel. This makes the storage of water media more efficient, makes ultrasound endoscopic diagnosis and treatment safer for patients, improves the efficiency and accuracy of examinations, and reduces the discomfort of patients during diagnosis and treatment, thereby improving the comfort of patients during diagnosis and treatment.

[0030] The inner diameter of the water bag 32 is 2.6 mm. According to different ultrasonic endoscopic microprobes, the length of the water bag can be set to various models such as 15.0 mm and 25.0 mm. The inner diameter of the water bag 32 can also be adaptively replaced according to different ultrasonic endoscopic microprobes and is not limited to 2.6 mm.

[0031] At least one first channel is connected to a second pipe 33, and a pressure sensor can be set inside the water bag 32. The second pipe 33 is used to discharge the water inside the water bag 32. By recording the input amount to the water bag 32, the water content inside the water bag 32 can be monitored, and the pressure sensor monitoring can be used to prevent the water bag 32 from bursting. The second pipe 33 can discharge part of the water for regulation when the internal pressure of the water bag 32 is too high or the input water amount is excessive. The size of the water bag 32 can also be adjusted through the second pipe 33 when inserting or removing the water bag during ultrasonic endoscopic diagnosis and treatment, which is convenient for taking and placing the water bag 32. Of course, the water outlet section of the second pipe 33 can be connected to a measuring cup or meter to record the discharged water, so that the purpose of precise control can be achieved. The water bag 32 only covers the ultrasonic endoscope microprobe, does not block the endoscope camera, does not affect the entry and observation of the endoscope, and can directly observe the expansion of the water bag 32 during operation, perform appropriate water injection, and reduce the risk of the water bag 32 self-explosion.

[0032] At least one first channel is connected to a pre-treatment assembly 10 via a first pipe 20. The pre-treatment assembly 10 is connected to a water bag assembly 30 via the first pipe 20. The water bag assembly 30 includes a water bag 32, one end of which is connected to a fixing member 31. The water entering the water bag assembly 30 can affect the results of an ultrasound examination. For example, if the water is too cold and the patient cannot tolerate the water bag, the water cannot cooperate with the ultrasound examination, or if the water contains a large amount of gas that affects ultrasound propagation, the pre-treatment assembly 10 is provided to pre-treat the water entering the water bag assembly 30. Specifically, the pre-treatment assembly 10 controls the temperature of the water so that the operating temperature of the water bag 32 is close to the patient's internal body temperature to resolve the tolerance issue and reduce the gas content in the water to improve the accuracy of the ultrasound examination results.

[0033] The pre-treatment component 10 includes a first shell 11, which has a built-in cavity. The cavity runs through both ends of the first shell 11. The side of the first shell 11 has a first tube body 16 that is connected to the cavity. The first tube body 16 is connected to the first pipeline 20. The medium is sent into the interior of the first shell 11 for treatment and then discharged through the first tube body 16 and the first pipeline 20. An electric control valve or valve can be optionally provided on the first pipeline 20 to control the opening or closing of the first pipeline 20. Of course, an electric control valve or valve can also be provided on the first tube body 16.

[0034] One end of the first shell 11 is detachably connected to the second sealing plate 13, and the other end of the first shell 11 is detachably connected to the first sealing plate 12. An injection pipeline 50 is provided on the second sealing plate 13, and the output port of the injection pipeline 50 is provided inside the cavity of the first shell 11. An exhaust valve is provided on the second sealing plate 13. The second sealing plate 13 and the first sealing plate 12 are used to seal the two ends of the first shell 11 to prevent leakage of the internal medium. The provided injection pipeline 50 is used to deliver the medium into the first shell 11. The injection pipeline 50 can be connected to the syringe, and the syringe can accurately measure to achieve the purpose of controlling the size of the water bag 32. The exhaust valve on the second sealing plate 13 can discharge the gas inside the first shell 11, thereby solving the problem of more gas in the medium.

[0035] A second shell 14 is provided inside the first shell 11. The second shell 14 is a rotating body structure and is provided with a through hole in the middle. One end of the second shell 14 is connected to the second sealing plate 13, and the diameter of the other end is smaller than the diameter of the end connected to the second sealing plate 13. Vents are provided around the surface of the second shell 14. When the water in the first shell 11 passes through the vents on the second shell 14, it helps the gas-liquid separator, promotes the discharge of gas in the water, reduces the gas content in the water, and improves the accuracy of the results of subsequent ultrasonic inspections. The vents can also intercept impurities in the water medium to eliminate the possibility of misdiagnosis caused by impurities in the water bag 32. In addition, after the water passes through the vents on the second shell 14, it helps to divert and converge the water, which has an improving effect on the uniformity of the water temperature distribution, and solves the problem that the uneven temperature of the water medium affects the subsequent delivery into the water bag 32, resulting in uneven temperature distribution of the water bag 32.

[0036] A third housing 15 is provided on the first sealing plate 12, with one end open. The opening of the third housing 15 is located within the cavity of the first housing 11, and a heating assembly 40 is housed within the third housing 15. The heating assembly 40 is used to heat the water inside the first housing 11 to a suitable temperature, thereby resolving the problem of temperature intolerance caused by the water bladder 32.

[0037] One end of the second shell 14 is connected to the second sealing plate 13, and the second sealing plate 13 has an annular mounting groove, which can be assembled with the end of the second shell 14. The other end of the second shell 14 is plugged into the opening of the third shell 15. The port of the second shell 14 has an annular segment, which is inserted into the opening of the third shell 15 to connect the third shell 15 with the second shell 14. The outlet end of the injection pipeline 50 is arranged in the second shell 14. The water delivered by the injection pipeline 50 is discharged downward in the second shell 14 and into the third shell 15. After the water is heated by the heating component 40, the water is discharged from the vent on the second shell 14 for water filtration and gas filtration operations. The amount of water delivered through the injection pipeline 50 is greater than the capacity of the water bag 32. Part of the water will remain in the third shell 15. When calculating the water volume in the water bag 32, the water capacity from the third shell 15 to the lowest water level vent position of the second shell 14 needs to be subtracted. Temporarily storing water in the third shell 15 can, on the one hand, quickly deliver temperature-controlled water to the next patient, shortening the diagnosis and examination time. On the other hand, the water temporarily stored in the third shell 15 helps to disperse impurities trapped by the vent to avoid accumulation and clogging of the vent.

[0038] The heating assembly 40 includes a heating rod 44, with a first ring body 42 disposed on the outside of the heating rod 44. A second ring body 46 is coaxially disposed within the inner ring of the first ring body 42, which is connected to the second ring body 46 via a second connecting plate 47. A fourth coaxial ring is disposed within the inner ring of the second ring body 46, which is connected to the second ring body 46 via a first connecting plate 45. The fourth ring body is sleeved over the heating rod 44, and after the two are connected and assembled, the fourth ring body cannot move relative to the heating rod 44. The first connecting plate 45 and the second ring body 46, the second connecting plate 47 and other components are made of heat-conducting materials. The heating rod 44 is used to heat the water body so that the water temperature is close to the temperature inside the patient's body, solving the problem that the temperature of the water bag 32 causes the patient to refuse to cooperate with the examination. The first ring body 42 is capable of contacting the inner wall of the third shell 15, so that the heating rod 44 is coaxial with the third shell 15. In this way, maintaining the position of the heating rod 44 for the flow into the water body helps to ensure the heating effect of the water body, and the second ring body 46, the first connecting plate 45 and other components are used to expand the heat exchange area of the water body and improve the heat exchange efficiency. For impurities trapped and deposited at the bottom of the third shell 15 by the vent, the second ring body 46, the first connecting plate 45 and other components can relatively reduce their re-suspension probability to ensure the circulation effect of the vent on the second shell 14.

[0039] The bottom of the heating rod 44 is connected to an external power source via a power line 41 .

[0040] The fixture 31 is a rotating body structure with a mounting channel in the middle, which runs through both ends of the fixture 31. Extension rings 311 extend outward from the upper and lower ends of the fixture 31. The rotating fixture 31 is easily inserted into the patient's body. The mounting channel is used for mounting the ultrasound microprobe, and the extension ring 311 limits the position of the external fastening rubber ring of the fixture 31. After the ultrasound microprobe is mounted in the mounting channel of the fixture 31, the fastening rubber ring can be placed on the exterior of the fixture 31 to apply a tightening force to the fixture 31, promoting tight contact between the fixture 31 and the ultrasound microprobe. The extension ring 311 prevents the fastening rubber ring from detaching.

[0041] The mounting channel of the fixing part 31 is provided with an inwardly concave first assembly ring groove 313, and the water bag 32 has a convex ring equipped with the first assembly ring groove 313. The first assembly ring groove 313 and the convex ring can realize the disassembly and assembly of the fixing part 31 and the water bag 32 and the sealing effect of the connection between the two. Water bags 32 of different lengths can be used selectively, which solves the problem of poor adaptability of the one-piece structure. In addition, when the water bag 32 is overfilled, a certain buffer release space can be provided through the first assembly ring groove 313, reducing the risk of self-explosion of the water bag 32 due to overfilling. The contact surface between the water bag 32 and the fixing part 31 has viscose and medical film. When in use, the medical film can be torn off to fill the viscose between the water bag 32 and the fixing part 31 to achieve sealing, prevent the medium from entering or discharging, and at the same time improve the connection tightness between the water bag 32 and the fixing part 31. The fixing part 31 and the water bag 32 of the present invention are preferably made of medical polymer materials. The finished fixing part 31 and the water bag 32 are sealed and bagged in a sterile packaging bag. The fixing part 31 and the water bag 32 are disposable medical products and are not to be used twice.

[0042] Example 2:

[0043] This embodiment provides a further improved solution based on the solution of embodiment 1, see the attached Figure 6 As shown, the fixture 31 is surrounded by an inner cavity 312. The inner cavity 312 is composed of at least two interconnected annular cavities. The annular cavities are arranged sequentially and interconnected along the axis of the fixture 31. The spacing between the upper and lower annular cavities is different. In this embodiment, the spacing between the upper annular cavities is smaller than the spacing between the lower annular cavities. The two adjacent annular cavities are interconnected, that is, the bottom of the upper annular cavity is interconnected with the top of the lower annular cavity. The arrangement of the annular cavities can improve the compatibility of the ultrasonic microprobe with the fixture 31, expanding the range of ultrasonic microprobe sizes that the fixture 31 can adapt to. When the ultrasonic microprobe is plugged into the fixture 31, the inner cavity 312 can deform to adapt the fixture 31 to the ultrasonic microprobe, thus resolving the problem of interference fit in the prior art, which causes wear and failure of the contact surface between the ultrasonic microprobe and the fixture 31. The inner cavity 312 is not set at the transmitting end of the ultrasonic microprobe to avoid air affecting the transmission. At the same time, a tightening rubber ring can be set outside the fixing member 31 to tighten the inner cavity 312 to deform it, thereby increasing the connection tightness between the fixing member 31 and the ultrasonic microprobe.

[0044] The fixing member 31 is formed by connecting the inner and outer casings. Figure 6 As shown, the plug-in end faces of the inner and outer casings can be coated with glue to increase the tightness of the connection between the two. The use of the inner and outer casing structure effectively reduces the processing difficulty and production cost of the fixing part 31, and has a better improvement effect on the cost and convenience of replacing spare parts.

[0045] Example 3:

[0046] This embodiment provides a further improved solution based on the solution of embodiment 1, see the attached Figure 3 , Attachment Figure 4 As shown, the heating rod 44 has an annular groove 43. The annular groove 43 reduces the diameter of a region on the surface of the heating rod 44. A third ring body is sleeved over the annular groove 43. The outer ring of the third ring body is connected to the second ring body 46 via a first connecting plate 45. The outer ring of the second ring body 46 is connected to the first ring body 42 via a second connecting plate 47. The third ring body can move relative to the heating rod 44 in the area of the annular groove 43. The diameter of the third ring body is smaller than the diameter of the portion of the heating rod 44 where the annular groove 43 is not formed.

[0047] The heating rod 44 is used to heat the water so that the water temperature is close to the temperature inside the patient's body, solving the problem that the temperature of the water bag 32 causes the patient to refuse to cooperate with the examination. The first ring body 42 is able to contact the inner wall of the third shell 15, so that the heating rod 44 is coaxial with the third shell 15. In this way, maintaining the position of the heating rod 44 for the flow into the water body helps to ensure the heating effect of the water body, and the second ring body 46, the first connecting plate 45, the second connecting plate 47, the third ring body and other components are used to expand the heat exchange area of the water body and improve the heat exchange efficiency. For impurities trapped and deposited at the bottom of the third shell 15 by the vent, the third ring body and the second ring body 46 can move up and down relative to the heating rod 44, further reducing the probability of re-suspension of impurities deposited at the bottom of the third shell 15 to ensure the circulation effect of the vent on the second shell 14.
