[0002] In clinical medicine, accurate positioning and stable adjustment of ultrasonic probes are key factors in ensuring the success of interventional treatment. Traditional ultrasonic probes mostly need to be adjusted manually, and medical staff need to obtain the ideal imaging position through visual observation and manual control. This method not only requires high technical experience, but also increases hand fatigue during operation and affects operational accuracy, especially in long-term or complex operations. In addition, due to the direct contact characteristics of ultrasonic probes, limited by spatial structures and the diversity of human tissues, the probes are often difficult to fix and the imaging is unclear, which hinders the diagnosis and treatment process and affects the treatment effect.

Specifically, two limit blocks are fixedly installed on the outer surface of the outer tube 11, and the limit blocks are respectively located on the upper and lower sides of the outer tube 11, so that the outer tube 11 can drive the movable sleeve 106 to move when it moves up and down.

A bobbin 110 is provided at the connection between the connecting rod 103 and the inner liner 101. The bobbin 110 is fixedly connected to one end of the connecting rod 103 close to the inner liner 101, and a driving rope 111 is wound around the free end of the wheel 108. The free end of the driving rope 111 is fixedly wound around the outer surface of the bobbin 110. The bobbin 110 and the inner liner 101 are clamped by a torsion spring.
[0021] Example 2: Please refer to Figure 2 , 56. An interventional ultrasonic probe adjustment device, based on Example 1, the adjustment device includes a drive ring 205, the drive ring 205 is located on the upper side of the rubber sleeve 202, a passive plate 204 is fixedly installed on the outer surface of the ultrasonic transducer 203, the passive plate 204 is located above the rubber sleeve 202, and the bottom end of the passive plate 204 is in contact with the outer surface of the rubber sleeve 202. Specifically, the rubber sleeve 202 is hollow inside. When the ultrasonic transducer 203 moves downward, the passive plate 204 is driven to move. At this time, the passive plate 204 squeezes the rubber sleeve 202 to turn it outward, and then any point of the passive plate 204 moves downward. Deflection, realizes the ultrasonic transducer 203 to deflect in the relative direction, and the rubber sleeve 202 has a certain elasticity, and can still return to the initial state after being deformed by force. A plurality of push rods 209 are rotatably installed on the inner end of the outer cylinder 4. The push rods 209 are arranged in a ring shape, and the upper end of the push rods 209 contacts the bottom end of the driving ring 205, and the lower end contacts the upper end of the passive plate 204. More specifically, the push rods 209 are "crescent" shaped, and the opening faces inward, thereby avoiding the hard contact between the upper and lower ends of the push rods 209 and the driving ring 205 and the passive plate 204, respectively, resulting in the ineffective transmission of the force; See also Figure 5 , 6 7. A stabilizing sleeve 208 is sleeved on the outer surface of the push rod 209, and a protective cover 201 is sleeved on the outer surface of the stabilizing sleeve 208. The stabilizing sleeve 208 is elastic, and the protective cover 201 is sleeved on the outer surface of the stabilizing sleeve 208 to prevent the stabilizing sleeve 208 from being separated from the push rod 209 under the action of its own elastic force. A driving sleeve 206 is rotatably installed on the inner upper end of the outer cylinder 4, and a passive rod 210 for stabilizing the ultrasonic transducer 203 is sleeved inside the driving sleeve 206. The bottom end of the passive rod 210 is in contact with the upper end of the ultrasonic transducer 203, and the driving ring 205 is sleeved on the outer surface of the passive rod 210. Specifically, the bottom end of the passive rod 210 is spherical, and a spherical groove is provided on the upper end of the ultrasonic transducer 203. When the bottom end of the passive rod 210 is in contact with the upper end of the ultrasonic transducer 203, no matter how the ultrasonic transducer 203 is offset, the bottom end of the passive rod 210 can follow the movement, and the bottom end of the driving ring 205 is fixedly installed with an arc-shaped protrusion 211, and the arc-shaped protrusion 211 contacts the upper end of the stabilizing sleeve 208. When the bottom end of the driving ring 205 is completely in contact with the upper end of the stabilizing sleeve 208, the arc-shaped protrusion 211 presses the stabilizing sleeve 208 downward and a depression appears. Then, when the driving ring 205 rotates, and drives the arc-shaped protrusion 211 to move along the upper end of the stabilizing sleeve 208, the downward pressing depression force is transmitted to the push rod 209 through the stabilizing sleeve 208, so that the push rod 209 can rotate downward in an orderly manner. like Figure 8As shown, a plurality of matching rods 212 are rotatably mounted on the outer surface of the driving sleeve 206, and the matching rods 212 are arranged in a ring shape. A plurality of sliding blocks 213 are slidably mounted on the upper end of the driving ring 205, and the sliding blocks 213 correspond to the matching rods 212, and one end of the matching rods 212 away from the driving sleeve 206 is rotatably connected to the sliding blocks 213. A movable plate 207 is sleeved on the inner end of the driving ring 205, and the movable plate 207 is sleeved on the outer surface of the passive rod 210, and the movable plate 207 has limited movable space in any direction in the driving ring 205, so that the deflection direction of the passive rod 210 is also restricted, so as to avoid the occurrence of a situation where the offset angle is too large and the restoration cannot be performed; See also Figure 8 , 9 , 10, the outer surface of the outer tube 11 is provided with a plurality of rectangular holes, and a driving block 302 is rotatably installed in each of the rectangular holes. The driving block 302 is connected to the outer tube 11 by a spring sheet. Under the elastic force of the spring sheet, the driving block 302 always maintains an outward rotation force. The inner bottom end of the driving sleeve 206 is provided with a plurality of locking grooves 307, and the locking grooves 307 correspond to the driving block 302. When the outer tube 11 moves downward, when the driving block 302 corresponds to the locking grooves 307, the driving block 302 is snapped into the locking grooves 307. Then, when the outer tube 11 rotates, the driving sleeve 206 can be driven to rotate through the driving block 302. The inner rod 12 is penetrated inside the outer tube 11, and the inner rod 12 can also be The deformable metal material can change with the change of the outer tube 11 (the metal material of the outer tube 11 and the inner rod 12 is such as nickel-titanium alloy, 316L stainless steel, etc.). More specifically, a driving device is integrated inside the operating handle 1, and the driving device can drive the outer tube 11 and the inner rod 12 to rotate, extend and shorten, and other functions. The driving device is a necessary function of the operating handle 1, which is an existing mature technology and will not be described in detail here. A card receiving ball 305 is fixedly installed at the bottom end of the inner rod 12, and a spherical cavity that can provide the card receiving ball 305 with movement is opened at the upper end of the passive rod 210. The card receiving ball 305 is located in the spherical cavity, so that the passive rod 210 can rotate in any direction with the card receiving ball 305 as the center of the circle; like Fig. 9 , 11As shown, the bottom end of the outer tube 11 and the upper end of the passive rod 210 are both provided with a plurality of slots 303, and the slots 303 are arranged in a ring shape and correspond to each other. An extension block 304 is fixedly installed on the outer surface of the inner rod 12. The extension block 304 is located between the outer tube 11 and the passive rod 210, and the extension block 304 can be clamped in the slot 303 when moving upward or downward, so as to limit the rotation of the passive rod 210. The bottom end of the outer tube 11 and the upper end of the passive rod 210 are both provided with a plurality of strips. Grooves, multiple strip grooves are arranged in a ring shape and the upper and lower groups correspond to each other, and the upper and lower groups of strip grooves are connected by a stabilizing pin 306, the stabilizing pin 306 can slide left and right at any inclination angle in the strip groove, and a matching ring 301 is provided between the outer tube 11 and the passive rod 210. The matching ring 301 is elastic, and the inner end of the matching ring 301 is fixedly connected to the stabilizing pin 306 in each strip groove, so that each stabilizing pin 306 can return to its initial state after changing its position.
[0022] The working principle of the present invention is: When in use, the present invention is inserted into the human body cavity, and then after reaching the designated position, the driving device inside the operating handle 1 drives the outer tube 11 to move downward, and the outer tube 11 moves downward while driving the movable sleeve 106 to move downward, then the driving rack 107 drives the driven gear 105 to rotate, and the driven gear 109 also starts to rotate under the meshing action with the driven gear 105, and the driven gear 109 drives the wire wheel 108 to rotate, at this time the wire wheel 108 rotates to pull the driving rope 111 so that it is wound on the outer surface, at this time the spool 110 rotates in the process of the driving rope 111 being pulled, and the torsion spring is also compressed accordingly, at this time the connecting rod 103 also starts to rotate, and pushes the fitting plate 102, so that the expansion sleeve 3 expands, and the organ tissues in the human body are stretched open, thereby providing space for the subsequent ultrasonic transducer 203 to move; At the same time, the outer tube 11 and the inner rod 12 push the passive rod 210 to move downward. At this time, the driving sleeve 206 is no longer sleeved on the outer surface of the passive rod 210, and the passive rod 210 squeezes the ultrasonic transducer 203 to move downward. At this time, after the outer tube 11 moves downward, the driving block 302 is clamped in the locking groove 307, and then the outer tube 11 rotates, and the driving sleeve 206 is driven to rotate through the driving block 302. The driving sleeve 206 drives the driving ring 205 to rotate through the matching rod 212. Then, when the driving ring 205 rotates, it drives the arc-shaped protrusion 211 to slide along the upper end of the stabilizing sleeve 208. Then, the force of the downward depression is transmitted to the pushing rod 209 through the stabilizing sleeve 208, so that the pushing rod 209 can rotate downward in an orderly manner. The pushing rod 209 rotates downward and squeezes the rubber sleeve 202 through the passive plate 204 to deform it. At this time, the ultrasonic transducer 203 realizes the change of the emission direction (specifically as shown in FIG. 21). Fig.12 As shown), to better capture the tissue information in the body; After the inspection is completed, the outer tube 11 and the inner rod 12 begin to retract, and the passive rod 210 returns to its initial state under the action of the clamping ball 305 and the matching ring 301, and the ultrasonic transducer 203 also returns to its initial state under the action of the elastic force of the rubber sleeve 202 itself. At this time, under the action of the upward movement of the movable sleeve 106, the passive gear 109 and the wire wheel 108 also begin to reverse, and the connecting rod 103 also drives the fitting plate 102 back to its initial state under the action of the elastic force of the torsion spring. At this point, the human body inspection is completed.
[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
