[0002] An endoscope is a tubular interventional instrument equipped with a visible light source. It can enter the human body through natural cavities such as the nasal cavity, airway, esophagus, stomach, intestines, urinary tract, etc., or through a small surgical incision. The endoscopic device has a balloon that can be expanded and deflated for a variety of purposes. Endoscopes are classified according to their functions, including endoscopes for the digestive tract, endoscopes for the respiratory system, endoscopes for the peritoneal cavity, endoscopes for the bile duct, etc. Among them, endoscopes for the respiratory system include rigid tube laryngoscopes, fiber laryngoscopes, electronic laryngoscopes, fiber bronchoscopes, electronic bronchoscopes, thoracoscopes, and mediastinoscopes.

DETAILED DESCRIPTION
[0037] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.
[0038] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.
[0039] Example 1
[0040] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, this embodiment 1 provides an endoscopic balloon, comprising a balloon 1 and a monitoring assembly. The monitoring assembly comprises an elastic member 2 disposed radially along the balloon 1 and a measuring assembly. The elastic member 2 is fixed at both ends of the balloon 1 so that the elastic member 2 generates a corresponding deformation based on the expansion of the balloon 1. The measuring assembly can measure the expanded diameter and pressure of the balloon 1 based on the deformation of the elastic member 2. Preferably, the elastic member 2 of the present invention is a tension spring, with both ends of the spring fixed to the interior of the balloon and disposed so that the spring passes through the center of the balloon. Therefore, when the balloon expands, the ends of the tension spring are stretched, causing the spring to generate a corresponding deformation. The deformation of the elastic member is monitored by the measuring assembly, thereby obtaining the expanded diameter and pressure of the balloon. Therefore, when applied to a narrow lumen, the size of the balloon expansion can be controlled in real time based on the actual size of the lumen, allowing for easy observation of the lumen while preventing irreversible damage to the cartilage within the lumen caused by excessive balloon expansion.
[0041] Further preferably, the elastic member 2 is disposed inside the balloon 1 along the radial direction of the balloon 1, passing through the center of the balloon 1. This allows the elastic member 2 to deform as the balloon 1 expands. Furthermore, the elastic member is disposed through the center of the balloon 1 so that it is positioned at the maximum diameter of the balloon 1. Therefore, when the balloon 1 expands, the deformation of the elastic member 2 can be calculated and converted into the maximum diameter of the balloon 1, allowing for more direct control of balloon expansion and avoiding damage to narrow cavities.
[0042] More preferably, Figure 3 and Figure 4As shown, both ends of the elastic member 2 are fixed to the inner wall of the balloon 1 by a fixing member 20 to ensure the stability of the tension spring during the stretching process and the measurement accuracy. Preferably, the back of the fixing member 20 is a curved connecting surface 21, and the curved connecting surface 21 is fixed to the inner wall of the balloon 1 by bonding or adsorption; for example, the curved connecting surface 21 can be fixed to the inner wall of the balloon 1 by adhesive, or fixed to the inner wall of the balloon 1 by vacuum adsorption. Ensure that the fixing member 20 is firmly connected to the balloon 1. Preferably, a guide member 30 is provided on the front of the fixing member 20, and a cylindrical guide opening 34 is formed in the guide member 30. A buckle 22 is provided in the guide opening 34. The buckle 22 is formed by extending inward from the circumferential inner wall around the guide opening 34, and an insertion hole 29 is reserved at the end of the buckle 22. The insertion hole 29 is used to install the elastic member 2 into the limited space of the buckle 22. Preferably, a space 23 is formed between the buckle 22 and the bottom surface of the fixing member 20 to limit the top or bottom coil of the elastic member 2. The top or bottom coil of the tension spring is then installed in the space 23, thereby forming a fixed connection between the tension spring and the fixing member. At the same time, the coil below the top or bottom coil extends outward along the guide opening 34. The guide opening 34 also guides the tension spring when it is stretched, preventing the spring from moving in other directions.
[0043] Preferably, the measuring component includes a drawstring 3 and a drawstring sensor 6, wherein one end of the drawstring 3 is connected to one end of the elastic member 2, that is, one end of the drawstring 3 can be connected to the top of the elastic member 2, and the other end of the drawstring 3 extends to the outside of the balloon 1 through the center of the elastic member 2, and is connected to the drawstring sensor 6 at the end of the drawstring 3. It should be noted that the end of the drawstring 3 refers to the end of the drawstring away from the balloon 1. Preferably, the drawstring 3 used in this application can be a steel wire rope. The drawstring sensor 6 can cause the drawstring 3 to be stretched when the tension spring is stretched, and shorten when the drawstring spring contracts, so that the tensile deformation of the tension spring can be obtained based on the stretched length of the drawstring.
[0044] Further preferably, to mount the measuring assembly, a first bearing seat 24 is provided below the buckle 22 of one of the fixing members 20. A first bearing 25 is provided within the first bearing seat 24, and a drawstring connector 26 is secured within the first bearing 25. The first bearing 25 ensures that the drawstring connector can rotate freely, preventing the drawstring from becoming tangled or bent. Preferably, a guide tube 33 is formed below the first bearing 25 to guide the drawstring connected to the drawstring connector 26, thereby guiding the expansion and contraction of the drawstring and preventing it from bending. Preferably, the outer diameter of the first bearing seat 24 is smaller than the inner diameter of the elastic member 2. This prevents the installation of the first bearing seat from interfering with the expansion or contraction of the drawstring spring.
[0045] Further preferably, the measurement assembly further includes a drawstring track 9, which is a hollow structure with openings at both ends. The drawstring track is used to allow the drawstring to be tightened. Preferably, the drawstring track 9 includes a horizontal section 91 and a vertical section 92. The vertical section 92 is arranged at the end of the horizontal section 91 and is connected to the horizontal section 91. The centerline of the vertical section 92 is aligned with the centerline of the elastic member 2. The horizontal section 91 extends from the drawstring sensor 6 along the drawstring 3 to the 1 / 2 position of the elastic member 2 located inside the balloon 1. That is, one end of the horizontal section can be fixed to the drawstring outlet of the drawstring sensor, and the other end extends to the middle 1 / 2 position of the elastic member, i.e., the spring. The connection between the horizontal section 91 and the vertical section 92 is an arc-shaped connection. The arc-shaped connection between the horizontal and vertical sections in the arc-shaped track allows the drawstring to expand and contract more easily with the expansion and contraction of the elastic member, thereby allowing the deformation of the elastic member to be more accurately measured by the displacement data of the drawstring, thereby more accurately understanding and controlling the expanded inner diameter of the balloon. Preferably, when the elastic member 2 is in a naturally extended state, the end of the vertical segment 92 abuts against the bottom of the guide tube 33 of the first bearing 25. When the elastic member 2 is stretched due to balloon expansion, the bottom of the guide tube 33 is driven outward by the inner wall of the balloon 1, while the pull rope track 9 does not move, so the end of the vertical segment is separated from the bottom of the guide tube 33.
[0046] Preferably, a plurality of second bearings 27 are provided at intervals within the rope track 9. The second bearings 27 are fixed to the inner wall of the rope track 9 via a second bearing seat. The rope 3 passes through the plurality of second bearings 27 and is slidably provided within the rope track 9. The provision of the plurality of second bearings can ensure that the rope is always kept taut within the rope track, thereby ensuring measurement accuracy.
[0047] According to a preferred embodiment, Figure 5 As shown, the drawstring track 9 is a transparent tubular structure. Multiple marking lines 31 are provided on the outer surface of the drawstring track 9 near the drawstring sensor 6. A reference line 32 is provided on the outer surface of the drawstring 3 near the drawstring sensor 6. When the drawstring 3 is displaced due to the elastic deformation of the elastic member 2, the reference line 32 can correspond to one of the multiple marking lines 31 to obtain the balloon expansion diameter and pressure based on the deformation of the elastic member 2. Each of the multiple marking lines 31 corresponds to the balloon expansion diameter and pressure value when the drawstring reference line moves to that position. Therefore, by providing the user with a more intuitive visual indication, the user can obtain the balloon expansion diameter and pressure by simply checking the position of the drawstring reference line.
[0048] Or, as Figure 7As shown, according to another preferred embodiment of the present application, the measuring component further includes a controller 11 and a display device 12. The controller 11 is connected to the drawstring sensor 6 to receive the output signal of the drawstring sensor 6 and display it through the display device 12. Preferably, the controller further includes a receiving module 13, a first conversion module 14, a second conversion module 15 and a third conversion module 16. The receiving module 13 is used to receive the drawstring displacement data transmitted by the drawstring sensor 6. The first conversion module 14 is connected to the receiving module 13 to calculate and convert the received drawstring displacement data into the expanded diameter data of the balloon 1. The second conversion module 15 is connected to the receiving module 13 to calculate and convert the received drawstring displacement data into the pressure data of the side wall of the balloon 1 against the cavity wall. The third conversion module 16 is connected to the receiving module 13 to calculate and convert the received drawstring displacement data into the displacement data of the balloon 1 in the cavity.
[0049] Preferably, the display device includes an expanded diameter display unit 17, a pressure display unit 18, and a displacement display unit 19. The expanded diameter display unit 17 is connected to the first conversion module 14 to display the balloon's expanded diameter data. The pressure display unit 18 is connected to the second conversion module 15 to display pressure data from the balloon's sidewall against the lumen wall. The displacement display unit 19 is connected to the third conversion module 16 to display displacement data of the balloon within the lumen. This allows the user to more accurately control balloon inflation based directly on the data displayed on the display device.
[0050] More preferably, Figure 1 As shown, the endoscopic balloon of the present invention also includes an inflation tube 7 and an inflation system 10 connected to the inflation tube 7. The distal end of the inflation tube 7 extends into the interior of the balloon 1 to inflate or deflate the balloon 1, thereby expanding or contracting the balloon 1. The inflation system 10 is used to inflate the balloon 1 through the inflation tube 7. Preferably, the inflation system 10 includes an air pressure pump 101, a pressure regulating valve 102, and a pressure relief valve 103. The controller 11 also includes a balloon inflation control module 35, which is connected to the air pressure pump 101, the pressure regulating valve 102, and the pressure relief valve 103, respectively. When the balloon needs to be inflated and expanded, the balloon inflation control module 35 controls the air pressure pump 101 and the pressure regulating valve 102 to inject gas at a specific controlled pressure into the balloon 1. When the balloon needs to be deflated, the balloon is deflated by opening the pressure relief valve 103 through the balloon inflation control module 35. Preferably, the display device 12 further includes a reference display unit 36 , and the balloon inflation control module 35 is connected to the reference display unit 36 , and displays reference expansion diameter data of the balloon 1 under a specific control air pressure based on the reference display unit 36 .
[0051] Preferably, the controller 11 further includes a comparison module 37. The first conversion module 14, the second conversion module 15, and the balloon inflation control module 35 are all connected to the comparison module 37. The comparison module 37 is connected to an alarm unit 38 of the display device 12. The comparison module 37 receives the actual balloon expansion diameter obtained by the first conversion module 14 and the reference balloon expansion diameter obtained by the balloon inflation control module 35, as well as the actual balloon pressure data obtained by the second conversion module 15 and the reference balloon pressure data obtained by the balloon inflation control module, for comparison and analysis. When the difference between the actual balloon expansion diameter and the reference balloon expansion diameter, or the difference between the actual balloon pressure and the reference balloon pressure, exceeds a preset error, an alarm is displayed via the alarm unit 38. Furthermore, when a large error occurs, the balloon position is manually adjusted to avoid balloon expansion restriction due to lumen problems.
[0052] Example 2
[0053] The difference between this embodiment 2 and embodiment 1 is that:
[0054] like Figure 2 、 Figure 6 and Figure 8 As shown, in this embodiment, the measurement assembly includes a patch sensor 8, which is spirally connected to the top or bottom layer of the elastic member 2 and is disposed within the confined space 23. The patch sensor 8 is a patch displacement sensor or a patch pressure sensor, and can be used to monitor the displacement data of one end of the elastic member 2 or the tension data of the elastic member 2.
[0055] More preferably, Figure 8 As shown, the controller 11 is connected to the patch sensor 8 to receive the output signal of the patch sensor 8 and display it on the display device 12. Preferably, the controller also includes a receiving module 13, a first conversion module 14, and a second conversion module 15. The receiving module 13 is used to receive the displacement data or tension data of one end of the elastic member transmitted by the patch sensor 8. The first conversion module 14 is connected to the receiving module 13 to calculate and convert the received elastic member displacement data or tension data into the expanded diameter data of the balloon 1. The second conversion module 15 is connected to the receiving module 13 to calculate and convert the received elastic member displacement data or tension data into the pressure data of the sidewall of the balloon 1 against the lumen wall. Preferably, the display device includes an expanded diameter display unit 17 and a pressure display unit 18. The expanded diameter display unit 17 is connected to the first conversion module 14 to display the expanded diameter data of the balloon.
