Description

Technical Field

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

[0002] In recent years, with the rapid development of digestive endoscopy technology, various mucosal and submucosal lesions in the digestive tract have been discovered. In order to determine the nature, layer and depth of the lesions, ultrasound endoscopy technology has been widely used, thus providing a more scientific basis for the formulation of treatment plans. However, there is an air gap between the ultrasound endoscopy instrument and the mucosa, and ultrasound waves are poorly transmitted in the air and absorbed, and it is impossible to obtain an effective reflected image. Therefore, clean water is needed as a medium to obtain a clear image. However, during the doctor's diagnosis and treatment process, the patient often has difficulty storing water media, secretion interference, intolerance to ordinary ultrasound endoscopy, etc., which makes it impossible to effectively complete the examination, and there is even a risk of suffocation. With the development of ultrasound endoscopy technology, water bags have come into being, solving some problems in ultrasound endoscopy 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 thus 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 prior art provides many solutions, such as the following prior art JP6125130B1. The patent discloses an ultrasonic endoscope and an injection device, in which the ultrasonic endoscope has an insertion body and a main body, the insertion part is arranged at the front end, the front end surrounds the ultrasonic wave, the ultrasonic transmitter and receiver for emitting ultrasonic waves is connected to the balloon and has 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 operation section and a supply pipeline connected to the universal cable setting, the patent solves the problem of the difficulty in 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 during ultrasonic endoscopic diagnosis and treatment and improving the diagnosis and treatment effect and comfort. 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 diagnosis and treatment comfort of the patient.

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 contacts 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 contact end surface of the fixing part 31 and 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 between the fixing part 31 and the ultrasonic probe during ultrasonic endoscope diagnosis. The head connection space and the air between the ultrasound probe and the water bag 32 affect the transmission of ultrasound. The water bag 32 is emptied and folded before use. When in use, water is introduced into the water bag 32 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 appropriately sized water bags reduce the discomfort of patients during diagnosis and treatment, thereby improving the comfort of patients during diagnosis and treatment.

[0024] 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 15.0 mm, 25.0 mm and other models.

The water content inside the water bag 32 can be monitored by recording the input amount to the water bag 32, and the bursting of the water bag 32 can be avoided by monitoring with the pressure sensor. The second pipeline 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 volume is excessive. The size of the water bag 32 can also be adjusted through the second pipeline 33 when inserting or removing the water bag during ultrasonic endoscopic diagnosis and treatment, so as to facilitate the placement and removal of the water bag 32. Of course, the water outlet section of the second pipeline 33 can be connected to a measuring cup or a meter to record the discharged water, so as to achieve the purpose of precise control. 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 self-explosion of the water bag 32.

[0026] At least one first channel is connected to a pre-treatment component 10 through a first pipeline 20. The pre-treatment component 10 is connected to a water bag component 30 through the first pipeline 20. The water bag component 30 includes a water bag 32, and one end of the water bag 32 is connected to a fixing member 31. For the water body sent into the water bag component 30, it can affect the results of the ultrasonic examination, such as the water body is too cold, causing the patient to be intolerant of the water bag and unable to cooperate with the ultrasonic examination, or the water body contains a lot of gas that affects the ultrasonic propagation, etc. Therefore, the pre-treatment component 10 is set to pre-treat the water body entering the water bag component 30, specifically, to control the temperature of the water body so that the use temperature of the water bag 32 is close to the patient's body temperature to solve the tolerance problem and reduce the gas content in the water body to improve the accuracy of the ultrasonic examination results.

[0027] 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 connected to the cavity. The first tube body 16 is connected to the first pipeline 20. The medium is sent into 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 a 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 a valve can also be provided on the first tube body 16.

[0028] 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. The second sealing plate 13 is provided with an injection pipeline 50, and the output port of the injection pipeline 50 is arranged inside the cavity of the first shell 11. The second sealing plate 13 is provided with an exhaust valve. 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 a 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 to solve the problem of more gas in the medium.

[0029] A second shell 14 is provided inside the first shell 11. The second shell 14 is a rotating body structure and has 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 connection end with the second sealing plate 13. Vents are arranged around the surface of the second shell 14. The water in the first shell 11 helps the gas-liquid separator when passing through the vents on the second shell 14, 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 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 the water to be diverted and converged, which has an effect on improving 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.

[0030] The first sealing plate 12 is provided with a third shell 15 with an opening at one end, the opening of the third shell 15 is provided in the cavity of the first shell 11, and a heating component 40 is provided in 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 enters 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 amount of water 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 and shorten 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 blockage of the vent.

[0032] The heating assembly 40 includes a heating rod 44, and a first ring body 42 is disposed outside the heating rod 44. A second ring body 46 coaxial with the first ring body 42 is disposed inside the first ring body 42, and the first ring body 42 is connected to the second ring body 46 via a second connecting plate 47.

The heating rod 44 is used to heat the water body so that the water temperature is close to the patient's body temperature, so as to solve 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 of water entering the 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 air vents, 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 air vents on the second shell 14.

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 to reduce 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 adhesive and medical film. When in use, the medical film can be torn off to fill the adhesive 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.

In this embodiment, the spacing between the upper cavities of the annular cavities is smaller than the spacing between the lower cavities. The two adjacent annular cavities are connected, that is, the bottom of the annular cavity located at the upper part is connected with the top of the annular cavity located at the lower part. The setting of the annular cavities can improve the degree of adaptation between the ultrasonic microprobe and the fixing part 31, so that the size range of the ultrasonic microprobe adapted by the fixing part 31 is expanded. When the ultrasonic microprobe is plugged into the fixing part 31, the inner cavity 312 can be deformed to make the fixing part 31 adapted to the ultrasonic microprobe, so as to solve the problem that the contact surface of the ultrasonic microprobe and the fixing part 31 is easily worn and failed due to the interference assembly method in the prior art. The inner cavity 312 is not arranged at the transmitting end of the ultrasonic microprobe to avoid air affecting the transmission. At the same time, a tightening rubber ring can be arranged 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.

[0037] The fixing member 31 is formed by connecting the inner and outer casings together. Figure 6 As shown, the plug-in end faces of the inner and outer casings can be coated with adhesive to increase the tightness of the connection between the two. 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.

[0038] Embodiment 3: This embodiment provides a further improved solution based on the solution of embodiment 1, see attached Figure 3 , Attachment Figure 4 As shown, the heating rod 44 has a section of annular groove 43. The setting of the annular groove 43 makes the diameter of a section of the surface of the heating rod 44 smaller. A third ring body is sleeved on the annular groove 43. The outer ring of the third ring body is connected to the second ring body 46 through a first connecting plate 45. The outer ring of the second ring body 46 is connected to the first ring body 42 through a second connecting plate 47. The third ring body can be displaced 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 heating rod 44 where the annular groove 43 is not provided.

[0039] The heating rod 44 is used to heat the water so that the water temperature is close to the temperature in the patient's body, so as to solve 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 can 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 of water entering 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 air 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 air vent on the second shell 14.
