Abstract
Description
Technical Field
[0001] The invention belongs to the field of medical equipment and relates to an automated medical auxiliary device, in particular to an auxiliary device used for puncture examination. Background Art
[0002] A puncture is a diagnostic technique that involves inserting a needle into a body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for angiography, or inject drugs into the body cavity. The purpose of a puncture is to draw blood for testing, transfuse blood, infuse fluids, and insert a catheter for angiography.
[0003] In current clinical punctures, due to differences in puncture sites, patient conditions, and doctor operating habits, the angle and direction of punctures also need to be adjusted according to actual conditions. Currently, when clinicians perform punctures, they generally control the angle and position of the puncture needle manually, and they operate more based on their own experience. For doctors with insufficient clinical experience, there may be certain errors in each operation, which will affect the accuracy and speed of the puncture, and even cause harm to the patient's body. Summary of the invention

[0008] The first slide and the third slide are driven by a linear motor or a motor screw, and can be moved to a specified position accurately and quickly through software control.

[0011] The first rotating platform and the second rotating platform are both driven by worm reducers. A high-step number stepper motor is used as a driving source to improve the rotation accuracy.
[0012] The linear guide rail is provided with an anti-slip rope, one end of which is fixed on the linear guide rail, and the other end is put on the puncture needle through an O-shaped anti-slip rubber ring, so that the doctor can check the puncture position after installing the puncture needle, and prevent the puncture needle from slipping and causing harm to the patient.
[0013] The included angle between the axis of the linear guide rail and the rotation plane of the second rotating platform is greater than or equal to 0° and less than 90°, and the linear guide rail rotates together with the second rotating platform.
[0014] The included angle of the linear lasers emitted by the two laser generators is greater than 0° and less than 90°, and the intersection of the two linear laser lines is located on the central axis of the linear guide rail.

[0023] The present invention will be described in detail below with reference to the accompanying drawings.
[0024] like Figure 1-Figure 3 As shown, the first slide 2 is composed of a guide rail and a slider. The guide rail is installed on the mounting seat 1 along the length direction of the bed. The slider is driven by a linear motor or a motor screw and slides along the guide rail.
[0025] The guide rail end surface of the second slide 3 is vertically mounted on the slider on the first slide 2 through a mounting seat, the upper surface of the slider of the second slide 3 is perpendicular to the upper surface of the slider of the first slide 2, and its slider is driven by a motor lead screw to move vertically along its guide rail.
[0026] The first rotating platform 4 is installed on the second slide 2 , and the rotating plane of the first rotating platform 4 is parallel to the moving plane of the slider of the second slide 2 .
[0027] like Figure 1-Figure 4 As shown, the slide rail end face of the third slide 5 is installed on the rotation plane of the first rotating platform 4 through a mounting seat, and the guide rail direction of the third slide 5 is perpendicular to the rotation plane of the first rotating platform 4 and the guide rail direction of the first slide 2. The first rotating platform 4 has a worm gear mechanism inside, which is driven by a synchronous motor to rotate the worm, and the worm drives the gear to rotate, thereby driving the rotating platform to rotate.
[0028] The second rotating platform 6 is installed on the slider plane of the third slide 5. The second rotating platform 6 has a worm gear mechanism inside. The worm is driven to rotate by a synchronous motor, and the worm drives the gear to rotate, thereby driving the rotating platform to rotate. The rotation plane of the second rotating platform 6 is parallel to the slider movement plane of the third slide 5.
[0029] The visual recognition module 9 is mounted on the slider of the third slide 5 by means of fasteners, and the camera shooting plane of the visual recognition module 9 is parallel to the slider movement plane of the third slide 5 .
[0030] The linear guide rail 8 and two low-power linear laser generators 7 are installed on the rotation plane of the second rotating platform 6. The angle between the axis of the linear guide rail 8 and the rotation plane of the second rotating platform 6 is greater than or equal to 0° and less than 90°, and the linear guide rail 8 can rotate with the second rotating platform 6.
[0031] The laser irradiation directions of the two low-power linear laser generators 7 are parallel to the axial direction of the linear guide rail 8. The angle of the linear lasers irradiated by the two laser generators is greater than 0° and less than 90°. During installation, the intersection of the two linear laser lines is adjusted to be located on the central axis of the linear guide rail 8, and a clear "cross" crosshairs can be formed when irradiated on the patient's body.
[0032] The linear guide rail 8 is a cylindrical hollow guide groove, the diameter of which is equal to the diameter of the puncture needle used, and a linear bearing is arranged inside so that the puncture needle can slide along its axis after being introduced.
[0033] The linear guide 8 is provided with an anti-slip rope, which is elastic like a rubber band. One end of the anti-slip rope is fixed on the linear guide, and the other end is put on the puncture needle through an O-shaped anti-slip rubber ring, so that the doctor can check the puncture position after installing the puncture needle to prevent the puncture needle from accidentally slipping and causing harm to the patient.
[0034] The doctor draws a positioning diagram with a specific shape on the part of the patient where puncture is required, then starts the puncture auxiliary device and inputs the required puncture angle; the second slide 3 of the puncture auxiliary device slides to the high position, and the visual recognition module 9 faces directly downward, and cooperates with the sliding of the first slide 2 and the third slide 5 to take multiple photos of the human body, and the position of the puncture positioning diagram is identified by the background computer; after the visual module 9 identifies the required puncture position of the human body, the three slides are controlled by the background computer software to cooperate with the two rotating platforms to move, so that the central axis of the linear guide is directly opposite to the center of the positioning diagram of the patient's required puncture part, and the bottom of the guide is 1-10cm away from the human body; at this time, two low-power linear laser generators 7 are turned on, and if the crosshairs are aligned with the center of the graphic of the required puncture part, the doctor will pass the puncture needle through the linear guide 8 for puncture, and manually control the puncture depth; if the crosshairs are not aligned, the computer controls the auxiliary device control end for fine adjustment.
