In general, a fixed angle needle insertion method is adopted for ultrasound-guided puncture, that is, a puncture needle penetrates into a target tissue from a skin surface layer at a certain angle at a puncture point which is a certain distance away from an ultrasound probe under the guidance of the ultrasound probe. The distance from the intersection point of the detection direction of the ultrasonic probe and the puncture direction of the puncture needle to the skin surface layer is the puncture depth. The theoretical puncture depth of the puncture adapter (H shown in fig. 5), i.e., the theoretical distance from the skin surface layer to the intersection point of the puncture direction of the puncture needle guided by the puncture adapter and the detection direction of the ultrasonic probe.
Referring to fig. 1 to 5, an ultrasound guided puncture device in one embodiment includes a mounting frame 1, a sliding mounting seat 2, a guiding device 3, a depth pointer 22 and a locking device 4, and a puncture depth of a guided puncture needle can be adjusted to meet guiding requirements of different puncture depths.
Referring to fig. 1 and 2, in particular, one end of the mounting bracket 1 can be mounted on an ultrasonic probe 5. The mounting rack 1 is provided with a sliding mounting seat 2 and a scale mark 111. The sliding installation seat 2 is arranged on the installation frame 1 in a sliding mode. The graduation marks 111 are arranged parallel to the sliding direction of the sliding mount 2. The mounting bracket 1 is used for supporting and mounting the rest of the components and is connected with the ultrasonic probe 5, so that the whole device is mounted on the ultrasonic probe 5. The ultrasound probe 5 may be mounted to the ultrasound probe 5 by any conventional snap-in configuration, or other configuration. The sliding direction of the sliding installation seat 2 is vertical to the detection direction of the ultrasonic probe 5 or forms a certain included angle with the detection direction. The scale lines 111 extend in a direction parallel to the sliding direction of the slide mount 2. In one embodiment, the mounting frame 1 is provided with a sliding guide rod 13, an axial direction of the sliding guide rod 13 is perpendicular to a detection direction of the ultrasonic probe 5, and the sliding mounting seat 2 is slidably sleeved on the sliding guide rod 13.

The theoretical penetration depth of the device is adjusted.
Referring also to fig. 5, a depth pointer 22 is disposed on the sliding mount 2 for indicating the reading of the graduation marks 111. The reading of the scale mark 111 corresponds to the guiding device 3, and the guiding theoretical puncture depth is set when the sliding installation seat 2 is at different positions of the installation frame 1. When the sliding installation seat 2 slides on the installation frame 1, the sliding distance s of the sliding installation seat 2 and the variation h of the theoretical puncture depth of the device are in linear correlation. For example, when the sliding direction of the slide mount 2 is perpendicular to the probe direction of the ultrasonic probe 5, h is s · tan α if the puncture angle is fixed to α. When the sliding direction of the sliding mounting seat 2 forms other included angles with the detection direction of the ultrasonic probe 5, it can be known that h is linearly related to s. The sliding installation seat 2 slides to change the distance between the guiding device 3 and the ultrasonic probe 5, when the puncture angle provided by the guiding device 3 is unchanged, the theoretical depth provided by the guiding device 3 is linearly related to the sliding distance of the sliding installation seat 2, the depth pointer 22 can directly indicate the theoretical puncture depth provided by the device along with the sliding of the sliding installation seat 2, and the theoretical puncture depth can be adjusted according to the needs of the puncture needle, so that the guiding requirements of different puncture depths are met.

The scale lines 111 are arranged in a plurality of groups, and each group of scale lines 111 is arranged corresponding to each puncture angle of the guide device 3. The angle adjusting mechanism 24 changes the included angle between the rotating arm 23 and the sliding installation seat 2, so that the guiding device 3 can provide different puncture angles, and meanwhile, the depth pointer 22 directly indicates the theoretical puncture depth provided by the device according to the corresponding scale mark 111, and the operation is simple and convenient.
Specifically, the angle adjusting mechanism 24 includes a rotary support base 241 and a pressing device 242. The rotation support base 241 is rotatably provided on the slide mount 2. The rotary support base 241 is provided with a plurality of support portions 2411, and the support portions 2411 are arranged around the rotating axis of the rotary support base 241 at intervals. The rotation of the support base 241 enables the rotation arm 23 to abut against any one of the support portions 2411, and the rotation arm 23 and the sliding installation base 2 form different included angles. The pressing device 242 has one end connected to the slide mount 2 and the other end connected to the rotating arm 23, and the pressing device 242 can provide pressing force to keep the rotating arm 23 in contact with any one of the support portions 2411. Specifically, the rotary support base 241 is of a ring structure, and a plurality of protrusions are arranged on the outer side wall of the rotary support base 241 and serve as support portions 2411. The protruding heights of the protrusions are different, so that when different supporting portions 2411 and rotating arms 23 are used, the included angles between the rotating arms 23 and the sliding installation seat 2 are different, and the puncture direction is changed. The rotating support 241 rotates to support the rotating arm 23 through different support portions 2411, so that different included angles are formed between the rotating arm 23 and the sliding installation seat 2, the puncturing angle is changed, and the pressing device 242 enables the rotating arm 23 to keep the included angle between the rotating arm 23 and the sliding installation seat 2. In one embodiment, the support portion 2411 can abut against one end of the rotating arm 23 away from the guide device 3. A strip-shaped through hole 231 is formed in one end of the rotating arm 23 away from the guide device 3, and the strip-shaped through hole 231 extends along the axial direction of the rotating arm 23. The compression device 242 includes a connecting bar 2421 and a press block 2422. One end of the connecting rod 2421 is rotatably arranged on the sliding mounting seat 2, and the rotating axis of the connecting rod 2421 is arranged in parallel with the rotating axis of the rotating arm 23.

A pressing block 2422 is screw-fitted on one end of the connecting rod 2421 penetrating the bar-shaped through hole 231 and presses the rotating arm 23 against the supporting portion 2411. After the connecting rod 2421 penetrates through the strip-shaped through hole 231, the pressing block 2422 is installed to press the rotating arm 23 conveniently, and meanwhile, the connecting rod 2421 is matched with the strip-shaped through hole 231 to prevent the rotating arm 23 from deflecting, so that the stability of the supporting part 2411 for supporting the rotating arm 23 is improved. In one embodiment, the middle of the rotating arm 23 is bent. The end of the rotating arm 23 remote from the guide 3 is bent toward the slide mount 2, deviating from the axis of the end of the rotating arm 23 where the guide 3 is provided. The bar-shaped through-holes 231 extend in the axial direction of the corresponding ends. One surface of the rotating arm 23 facing the slide mount 2 abuts against the support portion 2411. The rotating arm 23 is bent to facilitate reducing the supporting height of the supporting portion 2411, so that the supporting stability is improved, and meanwhile, when the pressing device 242 presses the rotating arm 23, an included angle between the connecting rod 2421 and the sliding mounting seat 2 is increased, so that the direction of the pressing force of the pressing device 242 on the rotating arm 23 and the axial included angle of the connecting rod 2421 are reduced, and the pressing effect of the connecting rod 2421 is improved. Specifically, the abutting position of the support portion 2411 and the rotating arm 23 is set to be a plane parallel to both the rotating axis of the rotating arm 23 and the rotating axis of the rotating support base 241, so that the rotating support base 241 is prevented from rotating when the support portion 2411 abuts against the rotating arm 23.
In one embodiment, the mounting bracket 1 is further provided with a rotatable scale shaft 11. The scale shaft 11 is disposed parallel to the sliding direction of the slide mount 2. The scale marks 111 are provided on the scale shaft 11, each scale mark 111 is provided at intervals in the circumferential direction of the scale shaft 11, and the scale marks 111 extend in the axial direction of the scale shaft 11. The rotary support 241 is in transmission connection with the scale shaft 11. The rotary support 241 is rotated to bring the support 2411 into contact with the rotary arm 23, thereby rotating the scale shaft 11 and turning the corresponding scale mark 111 toward the depth pointer 22. Specifically, when each support 2411 is rotated to abut against the rotating arm 23, the corresponding scale mark 111 is turned toward the depth pointer 22. The scale shaft 11 rotates with the rotary support 241, so that the depth pointer 22 automatically points to the scale line 111 corresponding to the puncture angle, thereby facilitating the confirmation of the puncture depth provided by the device and preventing the puncture depth provided by the wrong reading device. In one embodiment, the sliding mount 2 is further provided with a transmission rotary block 21. The rotation axis of the transmission rotary block 21 is parallel to the rotation axis of the rotation support base 241. The transmission rotary block 21 is in transmission connection with the rotary support base 241. The mounting rack 1 is also provided with a transmission shaft 12 parallel to the scale shaft 11.
