Examples
Referring to fig. 1, an angle-adjustable ultrasonic probe penetration apparatus includes: a fixed assembly 20 fixed to the ultrasonic probe 10, and a movable assembly 30 connected to the fixed assembly 20.
The fixing assembly 20 includes: the ultrasonic probe comprises a fixed block 21 contacted with the side wall of the ultrasonic probe 10 and arc clamps 22 hinged to two sides of the fixed block 21 respectively, wherein the fixed block 21 and the arc clamps 22 are specially designed for the shape of the ultrasonic probe 10. The end surface of the fixed block 21 far away from the ultrasonic probe 10 is contacted with the movable assembly 30, and the movable assembly 30 can be connected to the ultrasonic probe 10 through the fixed block 21 and the arc clamp 22, so that the ultrasonic probe 10 can be matched with the ultrasonic probe to complete puncture under ultrasonic development.
The end of the arc-shaped clamp 22 far away from the fixed block 21 is respectively provided with a boss 23, and the bosses 23 are provided with corresponding through holes, so that the two arc-shaped clamps 22 can be connected and fixed through the bayonet lock, and the arc-shaped clamps 22 are prevented from easily changing positions relative to the ultrasonic probe 10.
The movable assembly 30 includes: a rotation guide mechanism 31 connected to the top end of the fixed block 21, a sliding guide mechanism 32 connected to the bottom end of the fixed block 21, and a puncture catheter 33 penetrating the rotation guide mechanism 31 and the sliding guide mechanism 32, respectively. The rotation guide mechanism 31 can change the position of the tip of the puncture catheter 33 by its own movement, and the slide guide mechanism 32 can change the position of the base end of the puncture catheter 33 by its own movement, so as to adjust the inclination angle of the puncture catheter 33.
Referring to fig. 2 and 3, the rotation guide mechanism 31 includes: the first guide block 311 connected with the fixed block 21, a rotary fluted disc 312 positioned above the first guide block 311, a driving gear 313 in rotary fit with the rotary fluted disc 312, and a screw rod 314 connected on the end face of the driving gear 313. The outer wall of the screw 314 is provided with knurling, which is convenient for the staff to screw and rotate. The screw 314 is located at the center of the top surface of the driving gear 313, and drives the driving gear 313 to rotate. The side wall of the rotary fluted disc 312 is provided with teeth meshed with the driving gear 313, so that the driving gear 313 can drive the rotary fluted disc 312 to synchronously rotate when rotating. The rotary fluted disc 312 is connected with the first guide block 311 through a rotary shaft 315, and the bottom end of the rotary shaft 315 is arranged on the first guide block 311 through a bearing, so that the rotary shaft 315 and the rotary fluted disc 312 can perform rotary motion relative to the first guide block 311. The top of the rotary shaft 315 is provided with a supporting step 318 contacting the bottom surface of the rotary toothed disc 312, and the rotary toothed disc 312 is supported by the supporting step 318.
And the first guide block 311 has a T-shaped structure, and the part below the rotating fluted disc 312 is a rod member with a relatively small size, so that excessive interference to the rotation of the puncture catheter 33 is not generated. And because of the first guide block 311, the driving gear 313 and the rotating fluted disc 312 can not do continuous circular motion, but do reciprocating motion within a certain range, so as to avoid collision between the puncture catheter 33 and the first guide block 311.
The rotary fluted disc 312 is also provided with a first guide hole 316 which is matched with the puncture catheter 33, and the first guide hole 316 moves circularly along with the rotation of the rotary fluted disc 312, so that the top end of the puncture catheter 33 is driven to change in position. The first guiding hole 316 is narrow in the middle and wide in both ends, and the first ball 317 in contact with the puncture catheter 33 is embedded in the middle of the hole wall of the first guiding hole 316, when the first guiding hole 316 performs circular motion, the puncture catheter 33 also rotates, the first ball 317 rolls with the outer wall of the puncture catheter 33, and friction resistance is avoided to be generated to the rotation of the puncture catheter 33. And both ends of the first guide hole 316 have an inner diameter larger than an outer diameter of the puncture catheter 33 so that the puncture catheter 33 can be rotated in the first guide hole 316 in a wide range without generating shaft resistance to the puncture catheter 33.
Referring to fig. 4 and 5, the slide guide mechanism 32 includes: the second guide block 321 connected with the fixed block 21 and the guide groove block 322 connected with the second guide block 321, wherein a penetrating spiral chute 323 is formed in the guide groove block 322, the spiral chute 323 is connected with the spiral slider 324 in a sliding manner, the bottom end of the puncture catheter 33 penetrates through the spiral slider 324, and the puncture catheter 33 is guided to be adjusted in angle along with the movement of the spiral slider 324 along the spiral chute 323.
The end of the screw chute 323 communicates with the end surface of the guide groove block 322 remote from the second guide block 321, thereby facilitating the insertion and removal of the screw slider 324. A sliding table 325 matched with the spiral sliding groove 323 is arranged at the top end of the spiral sliding block 324, so that the spiral sliding block 324 cannot easily slide out of the spiral sliding groove 323. The inner wall of the through hole on the spiral chute 323 has a structure with two wide ends and a narrow middle, and when the puncture catheter 33 rotates in the spiral slider 324, the puncture catheter 33 can be prevented from interfering with the inner wall of the through hole.
Referring to fig. 1 and 6, the puncture catheter 33 includes: the thin section 331 matched with the first guiding hole 316 and the thick section 332 matched with the spiral sliding block 324, the thick section 332 and the thin section 331 can be in sliding fit, and the guiding length of the puncture catheter 33 can be conveniently adjusted according to the length requirement of the puncture needle. And the inner diameter of the end part of the thick section 332 far from the thin section 331 is identical with the inner diameter of the thin section 331, so that the puncture needle is prevented from colliding with the inner wall of the thick section 332 when penetrating out of the thick section 332.
The end of the thick section 332, which is far from the thin section 331, is further provided with a probe mechanism 34. The probe mechanism 34 is used for sending a signal to the human body, and the signal medium is a medium which can be developed by the ultrasonic probe 10 and is used for simulating the guiding direction of the puncture catheter 33 (i.e. the puncture path of the puncture needle), so that the puncture precision is further ensured.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
