Description

Technical Field

[0001] The invention belongs to the field of medical instruments, and in particular relates to an anesthesia puncture auxiliary positioning device. Background Art

[0002] As an indispensable medical device in hospitals, puncture needles are often used in conjunction with other equipment to accurately locate and relieve patients' pain. When performing anesthesia puncture, fixing the puncture needle is a key step. In order to improve the accuracy and efficiency of puncture, doctors usually use ultrasound probes to assist, so that the puncture needle can accurately reach the target site under the guidance of ultrasound images.

[0003] However, in actual operation, since this series of complex actions are often completed by the same doctor, it is easy for the ultrasound probe and the puncture needle to be not in the same vertical plane and cannot remain parallel to each other. This misalignment or angle will cause the doctor to be unable to see the puncture needle completely and clearly, thereby prolonging the puncture time and may even increase the difficulty of the operation and the risk of patient injury. Therefore, how to ensure that the ultrasound probe and the puncture needle maintain the correct relative position and angle during the operation has become an urgent problem to be solved. Summary of the invention

[0004] The present invention is intended to provide an auxiliary positioning device for anesthesia puncture, so as to solve the problem of inaccurate relative position between an ultrasonic probe and a puncture needle during operation in the prior art.

[0005] An anesthesia puncture auxiliary positioning device in this scheme includes a connecting arm, a clamp and a bracket. The clamp is used to fix the ultrasonic probe. The clamp is connected to the connecting arm. The bracket is connected to the outside of the clamp or the bracket is connected to the connecting arm. The bracket is provided with a guide block, and the guide block is provided with a guide groove. The central axis of the guide groove is parallel to the central axis of the clamp and is in the same vertical plane.

[0006] The working principle of this solution is: the clamp is used to tightly and firmly fix the ultrasound probe to ensure its stability and accuracy during operation. The design of the clamp facilitates doctors to quickly install and remove the ultrasound probe, while ensuring that the position of the probe will not move due to operation. The connecting arm serves as a bridge between the clamp and the bracket. The bracket is connected to the outside of the clamp or to the connecting arm to ensure that the position of the clamp and the guide block always maintains consistent changes. The guide block provided on the bracket has a guide groove, so when the position of the ultrasound probe is determined, the central axis of the guide groove is always parallel to the central axis of the clamp and is in the same vertical plane. This design ensures that the puncture needle can be aligned with the field of view of the ultrasound probe when passing through the guide groove.

[0007] When in use, the doctor can puncture the puncture needle along the direction of the guide groove. Since the central axis of the guide groove is parallel to the central axis of the ultrasound probe and is in the same vertical plane, the puncture needle can always remain in the field of view of the ultrasound probe during the puncture process, thereby achieving accurate positioning of the puncture needle.

[0008] The beneficial technical effects of this solution are:

[0009] 1. By fixing the ultrasound probe and providing a guide path for the puncture needle, the device can significantly improve the accuracy of anesthesia puncture. Doctors can see the position and movement trajectory of the puncture needle more clearly.

[0010] 2. Since the puncture needle can quickly reach the target site under the guidance of ultrasound images, the device helps to shorten the puncture time and improve the efficiency of the operation.

[0011] 3. The design of the device enables the ultrasound probe and the puncture needle to maintain the correct relative position and angle, thereby reducing the difficulty and risk of operation. Doctors can focus more on the surgical operation itself without worrying about the misalignment between the ultrasound probe and the puncture needle.

[0012] 4. By improving the accuracy and efficiency of puncture, the device helps reduce complications and adverse reactions during surgery, thereby improving patient safety.

[0013] Furthermore, the clamp includes a rigid fixing seat connected to the connecting arm and a flexible connecting belt for winding around the outside of the ultrasonic probe, and the fixing seat is provided with a buckle for the connecting belt to pass through, and the buckle is used to fix and release the connecting belt. The rigid fixing seat is a part of the clamp and is firmly connected to the connecting arm.

[0014] This connection ensures that the clamp can move and adjust its position as a whole with the connecting arm. The flexible connecting band is designed to be wrapped around the outside of the ultrasound probe handle. This design allows the connecting band to be adaptively adjusted according to the shape and size of the ultrasound probe, thereby ensuring a tight fixation effect. The buckle fixes the end of the connecting band after wrapping, forming a closed loop so that the ultrasound probe can be well fixed. The clamp design can provide a stable fixation effect to ensure that the ultrasound probe will not move or fall off during surgery. The clamp design in this anesthesiology puncture auxiliary positioning device combines rigid and flexible structures, providing a stable and flexible option for fixing the ultrasound probe.

[0015] Furthermore, an airbag strip made of elastic material is connected to the inner side of the middle section of the connecting belt, and an air blowing port is provided on the airbag strip. The airbag strip is in contact with the handle of the ultrasonic probe, and air is blown from the air blowing port to support the airbag strip. The airbag strip in this solution is made of elastic material, and the blown gas can be reasonably dispersed according to the different shapes of the handle, so that it fits better with the handle of the ultrasonic probe, and thus the fixing effect is better.

[0016] Furthermore, the outer wall of the bracket is provided with threads, the bracket is connected to the guide block, two nuts are threadedly connected to the bracket, a strip-shaped adjustment hole is provided on the connecting arm, the bracket passes through the adjustment hole, and the two nuts are located on both sides of the connecting arm. This solution combines the structures of the bracket, the double nuts and the adjustment hole of the connecting arm to provide enhanced stability and adjustability.

[0017] Furthermore, the bracket is provided with a marking line in the same length direction thereof, and the connecting arm is provided with a reference line corresponding to the position of the marking line. When the marking line corresponds to the reference line position, it indicates that the central axis of the guide groove is parallel to the central axis of the clamp.

[0018] During the surgical preparation stage, the doctor can make fine adjustments to the bracket by observing the positional relationship between the marking line and the reference line to ensure that the central axis of the guide groove is parallel to the central axis of the clamp. Once the two are parallel, it can ensure that the ultrasound probe and the puncture needle maintain the correct relative position and angle during the operation, thereby improving the accuracy and safety of the operation.

[0019] Furthermore, the connecting arm is provided with a positioning reference ruler, which includes a slide bar and a positioning bar perpendicular to the slide bar, the slide bar is slidably connected to the connecting arm, and the slide bar is located between the clamp and the guide block. The positioning reference ruler added to the connecting arm provides a more precise adjustment and positioning means for the puncture auxiliary positioning device of the anesthesiology department.

[0020] Furthermore, the side of the fixing seat adjacent to the ultrasonic probe is an arc surface, and the arc surface is provided with a silicone pad. The design of the arc surface helps to increase the contact surface or increase the contact points between the fixing seat and the ultrasonic probe, and the silicone pad enhances the anti-slip property and stability, and enhances the fixing effect between the ultrasonic probe and the fixing seat.

[0021] Furthermore, the device also includes a clamping mechanism, which includes a pair of clamping blocks for clamping on both sides of the ultrasound probe, and a spring is used between the pair of clamping blocks to provide a force to approach each other. The clamping mechanism clamps the ultrasound probe by a pair of clamping blocks that use a spring to provide a force to approach each other. This design not only increases the stability of the probe, but also improves the versatility and ease of operation of the device. The spring not only provides a clamping force, but also allows the clamping mechanism to adapt to probes of different sizes to a certain extent, increasing its versatility. Stable clamping helps to ensure accurate transmission and reception of ultrasonic signals, thereby improving the accuracy of detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 1 is basically as attached Figure 1 and Figure 2 As shown: an auxiliary positioning device for anesthesia puncture, including a clamping mechanism, a connecting arm 1, a clamp and a bracket, the clamp is used to fix the ultrasonic probe, the clamp includes a rigid fixing seat 14 connected to the connecting arm 1 and a flexible connecting belt 12 used to wrap around the outside of the ultrasonic probe, the inner side of the middle section of the connecting belt 12 is connected to an airbag strip 10 made of elastic material, the airbag strip 10 is provided with an air blowing port, and a cover 11 is provided at the air blowing port. A buckle 7 is provided on the fixing seat 14 for the connecting belt 12 to pass through, a through hole 8 is provided on the buckle 7 for the connecting belt 12 to pass through, and a threaded hole connected to the through hole 8 and perpendicular is also provided, a bolt 6 is threadedly connected in the threaded hole, such a buckle 7 is used to fix and loosen the connecting belt 12, and the side of the fixing seat 14 adjacent to the ultrasonic probe is an arc surface, and a silicone pad 13 is provided on the arc surface.

[0027] A screw rod is used as the bracket 18, that is, the surface of the bracket 18 is provided with a thread, the bracket 18 is connected to the guide block 20, the guide block 20 is provided with a guide groove 21, the central axis of the guide groove 21 is parallel to the central axis of the clamp and is in the same vertical plane. Two nuts 17 are threadedly connected to the bracket 18, and a bar-shaped adjustment hole 22 is provided on the connecting arm 1. The bracket 18 passes through the adjustment hole 22 and can slide left and right in the adjustment hole 22. The two nuts 17 are located on both sides of the connecting arm 1.

[0028] The bracket 18 is provided with a marking line 19 parallel to the axial direction of the bracket 18, and the connecting arm 1 is provided with a reference line corresponding to the position of the marking line. When the marking line 19 corresponds to the reference line position, it indicates that the central axis of the guide groove 21 is parallel to the central axis of the clamp.

[0029] A positioning reference ruler is provided on the connecting arm 1, and the positioning reference ruler includes a square slide rod 15 and a positioning strip 16 perpendicular to the slide rod 15. A square hole is opened on the connecting arm 1, and the slide rod 15 is slidably connected to the connecting arm 1, and the slide rod 15 is located between the clamp and the guide block 20.

[0030] The clamping mechanism includes a pair of clamping blocks 3 for clamping on both sides of the ultrasound probe. The clamping blocks 3 are in a "concave" shape, and the two ends of the clamping blocks 3 are respectively located above and below the connecting arm 1. The middle of the clamping blocks 3 is located on the rear side of the connecting arm 1 (i.e., the side away from the fixing seat 14). A spring 4 is used between the pair of clamping blocks 3 to provide a force to approach each other. Specifically, two mounting blocks 5 are connected to the upper and lower surfaces of the connecting arm 1. A guide rail 2 is fixedly connected between the two mounting blocks 5. The clamping blocks 3 are slidably connected to the guide rail 2. In this solution, a spring 4 is connected between the clamping blocks 3 and the mounting blocks 5. The spring 4 is sleeved on the outer periphery of the guide rail 2. When clamping the ultrasound probe, the spring 4 is in a compressed state, so the spring 4 generates a clamping force in the direction of the ultrasound probe, thereby reinforcing the stabilizing effect on the ultrasound probe and keeping its central axis on a vertical line, so that it can be more stably kept perpendicular to the puncture point.

[0031] The specific implementation process is as follows: open the flexible connecting belt 12, separate a pair of clamping blocks 3 to both sides, and let the handle 9 of the ultrasonic probe pass through the clamping blocks 3. The spring 4 is squeezed, and the handle 9 rests on the silicone pad 13 on the curved surface of the fixing seat 14. Then the flexible belt goes around the handle 9, passes through the buckle 7 and is fixed. The restoring force of the spring 4 is used as a clamping force to strengthen the stability of the ultrasonic probe. After the doctor holds the handle 9 of the ultrasonic probe to determine the puncture point, the handle 9 is perpendicular to the surface where the puncture point is located. In this state, the guide groove 21 is also perpendicular to the puncture point. The puncture needle reaches the puncture point along the guide groove 21, so that the puncture needle and the probe are kept in the same plane and parallel, and aligned with the field of view of the ultrasonic probe. Therefore, the puncture needle can always remain in the field of view of the ultrasonic probe during the puncture process, thereby achieving accurate positioning of the puncture needle.

[0032] Embodiment 2 differs from Embodiment 1 in that the position of the spring 4 is adjusted between the two clamping blocks 3. When clamping the ultrasonic probe, the spring 4 is stretched, and the restoring force of the spring 4 contracting toward the middle serves as the clamping force, so that the clamping blocks 3 clamp the ultrasonic probe.
