[0015] Preferably, the movable ball is fitted inside the limiting plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The optical ultrasonic endoscope for easy observation is provided with a connecting outer sleeve, a mounting sleeve, a transparent observation ring, a first glass fiber tube, a second glass fiber tube, a micro high-frequency ultrasonic probe, a connecting plate, a limiting plate, a sliding groove, a first micro motor, a first winding roller, a first gravity pull line, a second gravity pull line, a first sliding column, a movable ball, a limiting column, a mounting frame, a micro drive motor, a second winding roller, an elastic pull rope, a mounting plate and a through groove. When in use, it is installed by connecting the outer sleeve and the mounting sleeve, and the transparent observation ring is transparent. The micro high-frequency ultrasonic probe is connected through the first glass fiber tube and the second glass fiber tube, and the micro high-frequency ultrasonic probe is used for shooting and observation. When the angle of the micro high-frequency ultrasonic probe needs to be adjusted, the second micro The motor drives the rotating shaft to rotate through the second micro motor, and then drives the first contact ring and the second contact ring to rotate through the rotating shaft. When the rotating shaft rotates clockwise, the first contact ring drives the first glass fiber tube and the second glass fiber tube to move to the back side. At this time, the first contact ring and the first glass fiber tube and the second glass fiber tube are bent. Then the first micro motor is started, and the first winding roller is driven to rotate clockwise through the first micro motor. At this time, the first winding roller will rotate and wrap the first gravity pull wire around the outer surface of the first winding roller. At the same time, the first gravity pull wire will pull the first sliding column, and the first sliding column will slide inside the sliding groove to change its position. The movable ball and the limit column can assist the first sliding column to stabilize. The first sliding column and the second sliding column can slide in the sliding groove, and the overall sliding effect is good. At the same time, when the first sliding column slides, it can also drive the mounting frame to change its position. At the same time, when the mounting frame changes its position, the mounting frame will drive the second winding roller to move. At this time, the elastic pull rope on the outer surface of the second winding roller will pull the pull rope connecting tube on the outer surface of the miniature high-frequency ultrasonic probe to move, so that the pull rope connecting tube will drive the miniature high-frequency ultrasonic probe to change its position as a whole, so that the miniature high-frequency ultrasonic probe is in a bent state, and the angle changes with the angle of movement of the first sliding column and the mounting frame in the sliding groove. That is, when a certain angle is needed for observation, the direction of the miniature high-frequency ultrasonic probe is first determined by rotating the first contact ring and the second contact ring, so that the first contact ring and the second contact ring are aligned. The bending angles of the two contact rings and the first glass fiber tube and the second glass fiber tube are determined, and then the first sliding column is adjusted to a suitable position inside the sliding groove, and then the micro-drive motor is started, and the second winding roller is driven to rotate by the micro-drive motor, so that the second winding roller wraps and reels the elastic pull rope on its surface. When the elastic pull rope is reeled in, the elastic pull rope will pull the pull rope connecting tube and the side block to move. At this time, the micro-high-frequency ultrasonic probe can be in a bent state, so that the micro-high-frequency ultrasonic probe can be used by real-time observation of the state to adjust to a suitable bending angle. When the micro-high-frequency ultrasonic probe is facing the back, the second micro-motor drives the rotating shaft to rotate counterclockwise, and the second contact ring will contact the first glass fiber tube and the second glass fiber tube.Then the first micro motor will also rotate, and when it is adjusted to the upper end angle of the back, the first micro motor will rotate counterclockwise, and the second gravity pull wire will be wound through the first winding roller, and then the second gravity pull wire can also complete the same operation of the first gravity pull wire. At the same time, when it is adjusted to the lower end operation, the first micro motor drives the first winding roller to rotate clockwise, and then the second gravity pull wire will be separated from the outer surface of the first winding roller under the rotation of the first winding roller, so that the second sliding column on the back of the second gravity pull wire will move downward inside the sliding groove. Similarly, when the micro high-frequency ultrasonic probe needs to be adjusted to the lower end angle in front, the first gravity pull wire on the surface of the first winding roller will be separated from the surface of the first winding roller, and then the first sliding column will move downward through the gravity of the movable ball, and then when it is adjusted to the appropriate angle, continue Start the micro-drive motor, and adjust the bending angle of the micro-high-frequency ultrasonic probe by winding the elastic pull rope around the outer surface of the second winding roller. Therefore, the design can adjust the orientation and bending angle of the micro-high-frequency ultrasonic probe separately, and the bending angle can be adjusted arbitrarily. The micro-high-frequency ultrasonic probe after adjusting the angle can be used for observations at some tricky angles. At the same time, these tricky observation angles are some grooves or holes on the back near the outer surface of the transparent observation ring. Therefore, when using this design, only the first micro-motor and the second micro-motor need to be driven. By observing the real-time camera of the micro-high-frequency ultrasonic probe during the driving process, the appropriate adjustment angle of the micro-high-frequency ultrasonic probe can be easily found. The overall observation effect of this design is good and the operation is convenient, which reflects the functionality of the design.

[0017] The optical ultrasonic endoscope which is convenient for observation is provided with a first abutment ring, a second abutment ring, a guide frame, a guide roller, an adaptor ring, a side block, a drawstring connecting tube, a stabilizing sleeve, a telescopic column, a telescopic tube and a limit frame. When in use, when the first abutment ring rotates clockwise to drive the miniature high-frequency ultrasonic probe to face forward, the first abutment ring will also drive the guide frame to rotate, and at the same time, the elastic drawstring will pass through the inside of the guide frame and abut against the outer surface of the guide roller. The design of the guide frame and the guide roller can limit the pulling and winding operations of the elastic drawstring to avoid the position shift of the elastic drawstring during the operation, and the second abutment ring can also complete the same operation as the first abutment ring. When the second resistance ring rotates and drives the miniature high-frequency ultrasonic probe to face the back, the stabilizing sleeve will move forward, so that the telescopic column will move inside the telescopic tube, and the telescopic column squeezes the spring to move. When the second resistance ring does not resist the first glass fiber tube and the second glass fiber tube, the telescopic column will automatically return to its original position, and the miniature high-frequency ultrasonic probe will also return to its original position. Similarly, the first resistance ring can also perform the same operation as the second resistance ring. When the first gravity pull wire and the second gravity pull wire are unwound on the surface of the first winding roller, the position of the first gravity pull wire and the second gravity pull wire can be limited and conveyed through the limit frame, and the overall limiting effect is better.

Therefore, the first contact ring 27 and the second contact ring 28 play a certain stress-bearing role, which facilitates the subsequent adjustment of the observation angle of the miniature high-frequency ultrasonic probe 8. The miniature high-frequency ultrasonic probe 8 is installed by connecting the outer sleeve 3 and the mounting sleeve 4, and the transparent observation ring 5 is transparent. The miniature high-frequency ultrasonic probe 8 is connected through the first glass fiber tube 6 and the second glass fiber tube 7. During shooting and observation, when the angle of the miniature high-frequency ultrasonic probe 8 needs to be adjusted, the second miniature motor 25 is started, and the second miniature motor 25 drives the rotating shaft 26 to rotate, and then the rotating shaft 26 drives the first contact ring 27 and the second contact ring 28 to rotate. When the rotating shaft 26 rotates clockwise, the first contact ring 27 drives the first glass fiber tube 6 and the second glass fiber tube 7 to move toward the back. At this time, the first contact ring 27 and the first glass fiber tube 6 and the second glass fiber tube 7 are bent, and then the first miniature motor 12 is started, and the first winding roller 13 is driven to rotate clockwise by the first miniature motor 12. At this time, the first winding roller 13 will wrap the first gravity pull line 14 around the first winding roller when rotating. The outer surface of the roller 13, and the first gravity pull line 14 will pull the first sliding column 16, and the first sliding column 16 will slide and change its position inside the sliding groove 11, and the movable ball 17 and the limit column 18 can assist the first sliding column 16 to slide stably inside the sliding groove 11, and the overall sliding effect is good. At the same time, when the first sliding column 16 slides, it can also drive the mounting frame 19 to change its position. At the same time, when the mounting frame 19 changes its position, the mounting frame 19 will drive the second winding roller 21 to move. At this time, the elastic pull rope 22 on the outer surface of the second winding roller 21 will pull the pull rope connecting tube 33 on the outer surface of the miniature high-frequency ultrasonic probe 8 to move, so that the pull rope connecting tube 33 will drive the miniature high-frequency ultrasonic probe 8 as a whole The changed position makes the miniature high-frequency ultrasonic probe 8 in a bent state, and the angle changes with the angle of movement of the first sliding column 16 and the mounting frame 19 in the sliding groove 11, that is, when a certain angle is needed for observation, the direction of the miniature high-frequency ultrasonic probe 8 is first determined by rotating the first contact ring 27 and the second contact ring 28, so that the bending angles of the first contact ring 27 and the second contact ring 28 and the first glass fiber tube 6 and the second glass fiber tube 7 are determined, and then the first sliding column 16 is adjusted to a suitable position in the sliding groove 11, and then the micro-drive motor 20 is started, and the second winding roller 21 is driven to rotate by the micro-drive motor 20, so that the second winding roller 21 winds and reels the elastic pull rope 22 on its surface,When the elastic pull rope 22 is rolled up, the elastic pull rope 22 will pull the pull rope connecting tube 33 and the side block 32 to move. At this time, the micro high-frequency ultrasonic probe 8 can be in a bent state, so that the micro high-frequency ultrasonic probe 8 can be used by observing the state in real time. When the micro high-frequency ultrasonic probe 8 is facing the back, the second micro motor 25 drives the rotating shaft 26 to rotate counterclockwise. At this time, the second contact ring 28 will contact the first glass fiber tube 6 and the second glass fiber tube 7, and then the first micro motor 12 will also rotate. When adjusted to the upper end angle of the back, the first micro motor 12 rotates counterclockwise, and the second gravity pull wire 15 is wound through the first winding roller 13, and then the second gravity pull wire 15 can also be completed. The same operation as the first gravity pull wire 14 is performed. At the same time, when it is adjusted to the lower end operation, the first micro motor 12 drives the first winding roller 13 to rotate clockwise, and then the second gravity pull wire 15 will be separated from the outer surface of the first winding roller 13 under the rotation of the first winding roller 13, so that the second sliding column on the back of the second gravity pull wire 15 will move downward inside the sliding groove 11. Similarly, when the micro high-frequency ultrasonic probe 8 needs to be adjusted to the front lower end angle, the first gravity pull wire 14 on the surface of the first winding roller 13 will be separated from the surface of the first winding roller 13, and then the first sliding column 16 will move downward through the gravity of the movable ball 17. Then, when it is adjusted to a suitable angle, continue to start the micro drive motor 20, and by wrapping the elastic pull rope 22 around The outer surface of the second winding roller 21 allows the bending angle of the miniature high-frequency ultrasonic probe 8 to be adjusted. Therefore, the present design can independently adjust the orientation and bending angle of the miniature high-frequency ultrasonic probe 8, and the bending angle can be adjusted arbitrarily. The miniature high-frequency ultrasonic probe 8 after adjusting the angle can be suitable for observations at some tricky angles. At the same time, these tricky observation angles are some grooves or holes on the back near the outer surface of the transparent observation ring 5. Therefore, when using the present design, only the first micromotor 12 and the second micromotor 25 need to be driven. By observing the real-time camera of the miniature high-frequency ultrasonic probe 8 during the driving process, the appropriate adjustment angle of the miniature high-frequency ultrasonic probe 8 can be easily found, which reflects the functionality of the design. The moving column is installed on the back side of the second gravity pull wire 15, and the second sliding column and the first sliding column 16 are both slidably installed inside the sliding groove 11. Before adjusting the angle of the miniature high-frequency ultrasonic probe 8, the direction of the miniature high-frequency ultrasonic probe 8 is first determined by the first contact ring 27 and the second contact ring 28. When the miniature high-frequency ultrasonic probe 8 is facing forward, the second micromotor 25 drives the first contact ring 27 to rotate clockwise, and vice versa. Then, the first micromotor 12 continues to rotate to determine the angle that the miniature high-frequency ultrasonic probe 8 needs to be adjusted. At the same time, the rotation of the micro drive motor 20 can also determine the bending angle of the miniature high-frequency ultrasonic probe 8 (that is, the original direction of the miniature high-frequency ultrasonic probe 8 will be to the right,Then, the second winding roller 21 is driven by the micro drive motor 20 to rotate and the elastic pull rope 22 is wound up, so that the direction of the miniature high-frequency ultrasonic probe 8 will slowly move forward, and then by continuing to wind up the elastic pull rope 22, the direction of the miniature high-frequency ultrasonic probe 8 will bend, and the miniature high-frequency ultrasonic probe 8 will be oriented to the left, which can achieve a large angle adjustment, and the overall adjustment angle can be adjusted according to the actual position to be observed). At the same time, the inclination angle of the direction of the miniature high-frequency ultrasonic probe 8 can be adjusted by the first sliding column 16. This design first determines the direction of the miniature high-frequency ultrasonic probe 8, and then adjusts the direction of the miniature high-frequency ultrasonic probe 8 again, and finally adjusts the inclination angle of the direction of the miniature high-frequency ultrasonic probe 8, so that the adjusted miniature high-frequency ultrasonic probe 8 can be convenient for observation; A first gravity pull line 14 is installed on the upper surface of the first winding roller 13, a second gravity pull line 15 is installed on the outer surface of the first winding roller 13, a first sliding column 16 is installed on the end of the first gravity pull line 14 away from the first winding roller 13, a movable ball 17 is installed inside the first sliding column 16, a limiting column 18 is fixedly connected to the top surface of the first sliding column 16, the limiting column 18 is slidably installed on the inner wall of the limiting plate 10, the first sliding column 16 and the sliding groove 11 are adapted to each other, a mounting frame 19 is installed on the right side surface of the first sliding column 16, and a mounting frame 19 is installed on the top surface There is a micro drive motor 20, the output end of the micro drive motor 20 passes through the top surface of the mounting frame 19 and is installed with a second winding roller 21, the outer surface of the second winding roller 21 is installed with an elastic pull rope 22, the second gravity pull wire 15 has the same structure as the first gravity pull wire 14, and the first gravity pull wire 14 and the second gravity pull wire 15 both move inside the sliding groove 11, the outer surface of the first gravity pull wire 14 is installed with a limit frame 37, the limit frame 37 is installed inside the limit plate 10, and the limit frame 37 is provided with two groups, when the first contact ring 27 rotates clockwise, the micro high-frequency ultrasonic probe 8 is driven to face the front When the guide frame 29 is rotated, the first abutment ring 27 will also drive the guide frame 29 to rotate. At the same time, the elastic rope 22 will pass through the inside of the guide frame 29 and abut against the outer surface of the guide roller 30. The design of the guide frame 29 and the guide roller 30 can limit the pulling and winding operations of the elastic rope 22 to prevent the elastic rope 22 from shifting during the operation. The second abutment ring 28 can also complete the same operation as the first abutment ring 27. When the second abutment ring 28 rotates to drive the micro high-frequency ultrasonic probe 8 to face the back, the stabilizing sleeve 34 will move forward, thereby the telescopic column 3 5 will move inside the telescopic cylinder 36, and the telescopic column 35 squeezes the spring to move. When the second abutting ring 28 does not abut the first glass fiber tube 6 and the second glass fiber tube 7, the telescopic column 35 will automatically return to its original position, so that the miniature high-frequency ultrasonic probe 8 will also return to its original position. Similarly, the first abutting ring 27 can also complete the same operation as the second abutting ring 28. When the first gravity pull wire 14 and the second gravity pull wire 15 are unwinding on the surface of the first winding roller 13, the position of the first gravity pull wire 14 and the second gravity pull wire 15 can be limited and conveyed by the limiting frame 37.

[0022] Working principle: When the staff uses the device, first connect the device to an external power supply to provide power support for the device. When in use, install it by connecting the outer sleeve 3 and the installation sleeve 4, and the transparent observation ring 5 is transparent. The micro high-frequency ultrasonic probe 8 is connected through the first glass fiber tube 6 and the second glass fiber tube 7. The micro high-frequency ultrasonic probe 8 is used to take pictures and observe. When it is necessary to adjust the angle of the micro high-frequency ultrasonic probe 8, the second micro motor 25 is started at this time, and the second micro motor 25 will drive the rotating shaft 26 to rotate, and then the rotating shaft 26 will drive the first contact ring 27 and the second contact ring 28 to rotate. When the rotating shaft 26 rotates clockwise, the first contact ring 27 will drive the first glass fiber tube 6 to rotate. The fiberglass tube 6 and the second glass fiber tube 7 move toward the back, at which time the first contact ring 27 and the first glass fiber tube 6 and the second glass fiber tube 7 are bent, and then the first micro motor 12 is started, and the first winding roller 13 is driven to rotate clockwise by the first micro motor 12. At this time, the first winding roller 13 will rotate and wrap the first gravity pull wire 14 around the outer surface of the first winding roller 13. At the same time, the first gravity pull wire 14 will pull the first sliding column 16, and the first sliding column 16 will slide inside the sliding groove 11 to change its position. The movable ball 17 and the limit column 18 can assist the first sliding column 16 to slide stably inside the sliding groove 11. At the same time, when the first sliding column 16 slides, it can also drive the mounting frame 19 to move forward. When the mounting bracket 19 changes its position, the mounting bracket 19 will drive the second winding roller 21 to move. At this time, the elastic drawstring 22 on the outer surface of the second winding roller 21 will pull the drawstring connecting tube 33 on the outer surface of the miniature high-frequency ultrasonic probe 8 to move, so that the drawstring connecting tube 33 will drive the miniature high-frequency ultrasonic probe 8 to change its position as a whole, so that the miniature high-frequency ultrasonic probe 8 is in a bent state, and the angle changes with the angle of movement of the first sliding column 16 and the mounting bracket 19 in the sliding groove 11, that is, when a certain angle is needed for observation, the direction of the miniature high-frequency ultrasonic probe 8 is first determined by rotating the first contact ring 27 and the second contact ring 28, so that the first contact ring 27 and the second contact ring 28 are aligned with the first contact ring 28. The bending angle of the glass fiber tube 6 and the second glass fiber tube 7 is determined, and then the first sliding column 16 is adjusted to a suitable position inside the sliding groove 11, and then the micro-drive motor 20 is started, and the second winding roller 21 is driven by the micro-drive motor 20 to rotate, so that the second winding roller 21 winds up the elastic pull rope 22 on its surface. When the elastic pull rope 22 is rolled up, the elastic pull rope 22 will pull the pull rope connecting tube 33 and the side block 32 to move. At this time, the micro-high-frequency ultrasonic probe 8 can be in a bent state, so that the micro-high-frequency ultrasonic probe 8 can be used by real-time observation of the state to adjust to a suitable bending angle. When the micro-high-frequency ultrasonic probe 8 is facing the back, the second micro-motor 25 drives the rotating shaft 26 to rotate counterclockwise.At this time, the second abutment ring 28 will abut against the first glass fiber tube 6 and the second glass fiber tube 7, and then the first micro motor 12 will also rotate. When adjusted to the upper end angle of the back side, the first micro motor 12 will rotate counterclockwise, and the second gravity pull line 15 will be wound through the first winding roller 13. Then the second gravity pull line 15 can also complete the same operation of the first gravity pull line 14. At the same time, when adjusted to the lower end operation, the first micro motor 12 drives the first winding roller 13 to rotate clockwise, and then the second gravity pull line 15 will be separated from the first winding roller 14 under the rotation of the first winding roller 13. 3, so that the second sliding column on the back of the second gravity pull line 15 will move downward inside the sliding groove 11. Similarly, when the miniature high-frequency ultrasonic probe 8 needs to be adjusted to the front lower end angle, the first gravity pull line 14 on the surface of the first winding roller 13 will be separated from the surface of the first winding roller 13, and then the first sliding column 16 will move downward through the gravity of the movable ball 17. Then, when it is adjusted to a suitable angle, the miniature driving motor 20 is started again, and the bending angle of the miniature high-frequency ultrasonic probe 8 is adjusted by winding the elastic pull rope 22 around the outer surface of the second winding roller 21; When the first resistance ring 27 rotates clockwise and drives the micro-high-frequency ultrasonic probe 8 to face forward, the first resistance ring 27 will also drive the guide frame 29 to rotate, and the elastic pull rope 22 will pass through the inside of the guide frame 29 and contact the outer surface of the guide roller 30. The design of the guide frame 29 and the guide roller 30 can limit the pulling and winding operations of the elastic pull rope 22 to prevent the elastic pull rope 22 from shifting during the operation. The second resistance ring 28 can also complete the same operation of the first resistance ring 27. When the second resistance ring 28 rotates and drives the micro-high-frequency ultrasonic probe 8 to face the back, the stabilizing sleeve 34 will move forward. , so that the telescopic column 35 will move inside the telescopic cylinder 36, and the telescopic column 35 squeezes the spring to move, when the second contact ring 28 does not contact the first glass fiber tube 6 and the second glass fiber tube 7, the telescopic column 35 will automatically return to its original position, so that the miniature high-frequency ultrasonic probe 8 will also return to its original position. Similarly, the first contact ring 27 can also complete the same operation of the second contact ring 28, and when the first gravity pull wire 14 and the second gravity pull wire 15 are unwound on the surface of the first winding roller 13, the position of the first gravity pull wire 14 and the second gravity pull wire 15 can be limited and conveyed through the limit frame 37. The above is all the working principles of the present invention.
