Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an ultrasonic probe auxiliary positioning device used for ECMO catheter placement operations at the emergency scene. Background Art

[0002] Ultrasound imaging technology uses ultrasound beams to scan the human body, and then obtains images by receiving and processing reflected signals. This technology can be used to obtain images of organs in the human body, and is widely used in clinical practice. During ECMO catheterization, ultrasound guidance is used to determine potential cannulation obstacles and assess the depth and angle of puncture. Most physicians rely heavily on ultrasound images during ECMO catheterization.

[0003] In the emergency room and outside the hospital, due to staff shortage and complex ECMO catheterization surgical environment, it is difficult to reposition the ultrasound probe when the catheterization doctor is disturbed while using the ultrasound equipment, and the catheterization operation cannot be completed by one person alone, which ultimately leads to prolonged catheterization time or inability to complete the catheterization operation, causing serious complications or even death to the patient.

[0004] In order to reduce the difficulty of ECMO cannulation and improve the auxiliary effect of ultrasound equipment on cannulation, we have developed a bed-fixed ultrasound probe auxiliary positioning mechanical arm that can be connected to the bed. The ultrasound probe is fixed at the end of the mechanical arm. When the doctor operates the ultrasound probe, it can be easily and flexibly moved in all dimensions and locked at any time, which assists the doctor in the use of ultrasound equipment in ECMO cannulation, improves the success rate of cannulation, and reduces the difficulty and time of cannulation.

[0008] However, the ultrasonic experiment auxiliary device has the following shortcomings: (1) The adjustment of the position and angle of all columns requires manual operation, and the locking of each joint requires manual operation separately, which is complicated; (2) When moving the robotic arm, it is necessary to overcome the friction at the joints and the gravity of the robotic arm.

[0020] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0022] like Figure 1 to Figure 2 As shown, an ultrasound probe auxiliary positioning device for ECMO catheterization operation at the emergency scene includes a bed fixing frame 5, which is an adjustable clamping structure, and the device can be firmly fixed to the target area of ​​the bed. The bed fixing frame 5 ensures that the device can be tightly and firmly fixed to the designated or target area on the bed. In practical applications, this stability is very important. It can effectively prevent the problem of inaccurate detection results caused by the shaking of the device when performing precision medical operations such as ECMO catheterization. Once the detection result is biased, it may directly affect the doctor's judgment, and then have an adverse effect on the patient's subsequent treatment, and even endanger the patient's life safety. The adjustability of the bed fixing frame 5 enables it to adapt to beds of different sizes and types, thereby ensuring excellent stability and practicality in various emergency scenarios. A mechanical probe weight input module is provided on the side surface of the bed fixing frame 5, and a mechanical suspension module 7 is connected to the upper end of the bed fixing frame 5. The upper end of the mechanical suspension module 7 is connected to an ultrasound probe fixing module 1. The ultrasound probe fixing module 1 is a quick-release component, and the corresponding adapter is replaced according to different ultrasound equipment. A locking button 2 is provided on one side of the ultrasonic probe fixing module 1 .

[0023] The mechanical suspension module 7 includes a plurality of support arms 4 connected end to end, one end of the support arm 4 is fixedly connected with a ball joint 3, and the other end of the support arm 4 is provided with a circular groove 8 corresponding to the ball joint 3, and the ball joint 3 at one end of the support arm 4 is meshed and connected with the circular groove 8 of the adjacent support arm 4. The opening radius of the circular groove 8 is smaller than the radius of the ball joint 3, so that the ball joint 3 can be firmly contained in the circular groove 8, thereby realizing a stable connection between the support arms 4. This connection method not only has excellent mechanical strength, but also can effectively prevent loosening or falling off during operation, thereby ensuring the stability and reliability of the entire mechanical suspension module 7.

[0024] A rectangular cavity 9 is provided inside the support arm 4, and the cavity 9 is connected with the groove 8. An electric push rod 10 is provided inside the cavity 9. The fixed end of the electric push rod 10 is fixedly connected to the end of the cavity 9 away from the groove 8, and the movable end of the electric push rod 10 is in contact with the ball joint 3 inside the groove 8. By controlling the telescopic movement of the electric push rod 10, the required torque can be provided for the ball joint 3, thereby realizing the angle adjustment and position movement between the support arms 4.

[0025] The robot arm probe weight input module 6 is electrically connected to the electric push rod 10, and the robot arm probe weight input module 6 is used to adjust the locking torque of the electric push rod 10. They work together to achieve precise control and suspension function of the robot arm. The weight data is input into the robot arm probe weight input module 6. The built-in algorithm of the robot arm calculates the torque applied by the electric push rod 10 at each ball joint 3 according to the input data. By continuously adjusting the locking torque of the electric push rod 10, the robot arm can gradually reach a state of balance with gravity and friction. In this state, even if each joint is in a loose state, the robot arm can maintain a stable suspension posture. This feature makes the robot arm more flexible, stable and easy to control during operation, greatly improving its work efficiency and accuracy.

[0026] The locking button 2 is also electrically connected to the electric push rods 10 . Pressing the locking button 2 can cause all the electric push rods 10 of the mechanical arm to provide a larger torque to lock the mechanical arm, so as to fix the position of the ultrasound probe.

[0027] Working principle: When using the auxiliary device, first weigh the ultrasound probe and adapter used this time, and input the weighed weight data into the robot arm probe weight input module 6. The built-in algorithm of the robot arm calculates the torque applied by the electric push rods 10 at each ball joint 3 according to the input data to achieve a balance between the robot arm as a whole and the gravity and friction force, so that the robot arm can be suspended at any time when each joint is loose. The robot arm is fixed to one side of the bed through the bed fixing frame 5, and is adapted and connected to the currently used ultrasound probe through the ultrasound probe fixing module 1. The user then holds the ultrasound probe fixing module 1 of the robot arm to image the blood vessels in the patient's body, and presses the locking button 2 when a suitable angle is found, so that all the electric push rods 10 of the robot arm provide a larger torque to lock the robot arm to fix the position of the ultrasound probe.

[0028] Therefore, the present invention adopts the above-mentioned ultrasonic probe auxiliary positioning device for ECMO catheter placement operation at the emergency scene, which has the following technical effects: (1) The mechanical suspension module is set up to solve the problem of physical exhaustion of doctors due to the weight of the probe during continuous operation, which affects the intubation efficiency and success rate; (2) By setting up a robot arm probe weight input module in conjunction with a mechanical suspension module, the problem of inaccurate secondary positioning when using an ultrasonic imaging instrument due to various factors is solved; (3) By setting a locking button, the problem that the ultrasonic probe cannot be suspended and fixed during use is solved.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
