Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a single-arm portable puncture positioning bracket device. Background Technology

[0002] In traditional manual puncture procedures, the operator typically uses one hand to stabilize the skin at the puncture site while holding the puncture needle in the other to make the insertion. Because the insertion direction is not fixed, this procedure often requires multiple attempts. After each attempt, a CT scan is needed to observe the needle's position and ensure it has accurately reached the target area. Due to the need for multiple insertions and scans, the entire puncture process is time-consuming, increasing patient pain and discomfort. Furthermore, multiple puncture attempts increase the risk of damaging surrounding healthy tissue, potentially leading to complications such as bleeding and infection. Moreover, because the insertion direction is not fixed, the operator often struggles to accurately reach the target area on the first attempt, resulting in a high puncture failure rate. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a single-arm portable puncture positioning support device.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A single-arm portable puncture positioning support device includes a column, an upper support frame movably mounted on the column, an upper positioning universal ring that moves laterally along the upper support frame, a lower support frame movably mounted on the column and located below the upper support frame, a lower positioning universal ring that moves laterally along the lower support frame, and a guide tube that provides a passage for the puncture needle. The working position of the guide tube is determined by the position of the upper positioning universal ring and the position of the lower positioning universal ring. In use, the guide tube passes through the upper positioning universal ring and the lower positioning universal ring.

[0005] Furthermore, both the upper and lower support frames include an outer rod with a hollow internal structure, an inner rod located inside the outer rod and capable of sliding along the outer rod, and a locking device for fixing the inner rod's position within the outer rod. The upper positioning universal ring is located at the end of the inner rod of the upper support frame, and the lower positioning universal ring is located at the end of the inner rod of the lower support frame. The end of the outer rod away from the positioning universal ring is movably mounted on the column.

[0006] Furthermore, the upper support frame and the lower support frame are respectively mounted on the column via connecting sleeves. The connecting sleeves can slide up and down along the column and can rotate around the column axis. The connecting sleeves are equipped with locking devices for positioning the upper support frame and the lower support frame on the column.

[0007] Furthermore, the column has multiple locking grooves, and the connecting sleeve has two sets of locking parts. The distance between the two sets of locking parts is the same as the distance between adjacent locking grooves. The locking parts pass through the connector and are inserted into the locking grooves on the column.

[0008] Furthermore, both the upper and lower positioning universal rings include a first circular plate, a first cavity formed inside the first circular plate, a second circular plate connected to the first cavity via a rotating shaft, and a fixing hole formed on the second circular plate. The first circular plate is rotatably mounted on the upper and lower support frames via a rotating head, and the rotation direction of the first circular plate around the upper and lower support frames is 90° with the rotation direction of the second circular plate around the first circular plate. The guide cylinders pass through the fixing holes of the upper and lower positioning universal rings respectively.

[0009] Furthermore, the support column can be detachably connected to the hospital bed.

[0010] Furthermore, a locking clamp is provided at the lower end of the column, which is used to lock the fixation frame onto the hospital bed.

[0011] Furthermore, the locking clamp includes a spring clamp having a first clamp and a second clamp, and a locking member disposed on the spring clamp. The locking member passes through the first clamp and locks onto the second clamp. Friction layers are respectively disposed on the clamping surfaces of the first clamp and the second clamp.

[0012] Furthermore, the guide cylinder includes a guide rod with a hollow internal structure, an end set at the top of the guide rod, and a sliding cylinder that slides along the guide rod. The sliding cylinder is equipped with a locking device. The end is located on the upper positioning universal ring, and the sliding cylinder is located on the lower positioning universal ring. The guide rod passes through the upper positioning universal ring and the lower positioning universal ring.

[0013] Furthermore, graduations are provided on the columns, upper support frame, and lower support frame.

[0014] The present invention has the following advantages: The single-arm portable puncture positioning support device provided by the present invention has a reliable structure and good performance. It adopts a single-arm structure, is small in size, easy to carry, and convenient to install. In addition, by fixing the upper and lower positioning universal rings respectively, and then inserting the guide tube into the two positioning universal rings and locking the guide tube, a clear and fixed channel can be established for the puncture needle, fixing the puncture direction of the puncture needle.

Detailed Implementation

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] like Figures 1 to 2 As shown, a single-arm portable puncture positioning support device includes a column 1, an upper support frame 2 movably mounted on the column 1, an upper positioning universal ring 3 that moves laterally along the upper support frame 2, a lower support frame 4 movably mounted on the column 1 and located below the upper support frame 2, a lower positioning universal ring 5 that moves laterally along the lower support frame 4, and a guide tube 6 that provides a passage for the puncture needle. The working position of the guide tube 6 is determined by the position of the upper positioning universal ring 3 and the position of the lower positioning universal ring 5. In use, the guide tube 6 passes through the upper positioning universal ring 3 and the lower positioning universal ring 5.

[0025] The column 1 is the main supporting structure of the device, a rod-shaped component used to support the upper and lower support frames 4. The upper positioning universal ring 3 can move laterally to adjust the upper position of the guide tube 6. The upper positioning universal ring 3 can move laterally along the upper support frame 2 and has a universal adjustment function, which can flexibly adjust the angle and position of the guide tube 6. By adjusting the position of the upper positioning universal ring 3, the working direction of the guide tube 6 can be initially determined. The lower support frame 4 is equipped with a lower positioning universal ring 5, which can also move laterally. The lower positioning universal ring 5 moves laterally along the lower support frame 4 and has a universal adjustment function, used to further adjust the position and angle of the lower end of the guide tube 6. After the positions of the upper positioning universal ring 3 and the lower positioning universal ring 5 are fixed, the guide tube 6 is inserted from the upper positioning universal ring 3 into the lower positioning universal ring 5 to establish a precise puncture channel for the puncture needle. In use, the guide tube 6 passes through the upper positioning universal ring 3 and the lower positioning universal ring 5. By adjusting the position and angle of these two universal rings, the direction and depth of the guide tube 6 can be precisely controlled. This design makes the puncture operation more accurate and reduces the difficulty and error of operation.

[0026] In addition, the upper support frame 2 and the lower support frame 4 are respectively equipped with scales for easy and intuitive display of the adjustment position. Both the upper support frame 2 and the lower support frame 4 include an outer rod 20 with a hollow internal structure, an inner rod 21 located inside the outer rod 20 and capable of sliding along the outer rod 20, and a locking element 22 for fixing the inner rod 21 in its moving position inside the outer rod 20. The upper positioning universal ring 3 is located at the end of the inner rod 21 of the upper support frame 2, and the lower positioning universal ring 5 is located at the end of the inner rod 21 of the lower support frame 4. The end of the outer rod 20 away from the positioning universal ring is movably mounted on the column 1. The outer rod 20 can rotate or move up and down around the column 1, and the inner rod 21 can move along the outer rod 20, thereby driving the lateral position movement of the universal ring. The locking element 22 can be a knob, a tightening screw, or other quick-locking mechanism to ensure that the inner rod 21 remains stable after adjustment.

[0027] To improve flexibility and ease of use, such as Figure 3As shown, in this invention, the upper support frame 2 and the lower support frame 4 are respectively mounted on the column 1 via connecting sleeves 23. The connecting sleeves 23 can slide up and down along the column 1 and can rotate axially around the column 1. The connecting sleeves 23 are equipped with locking elements 22 for positioning the upper support frame 2 and the lower support frame 4 on the column 1. The ability of the connecting sleeves 23 to slide up and down along the column 1 allows for adjustment of the height of the upper support frame 2 and the lower support frame 4. The axial rotation of the connecting sleeves 23 around the column 1 allows the upper support frame 2 and the lower support frame 4 to rotate horizontally. This rotation function further expands the adjustment range of the positioning universal ring and enhances the flexibility of the device. The locking elements 22 on the connecting sleeves 23 are used to fix the positions of the upper support frame 2 and the lower support frame 4 on the column 1. The locking elements 22 can be knobs, tightening screws, or other quick-locking mechanisms to ensure that the support frames remain stable after adjustment.

[0028] To improve the stability of the connection between the upper and lower support frames on the column 1, this invention provides multiple locking grooves 10 on the column 1, evenly distributed along the axial direction of the column 1. The connecting sleeve 23 is equipped with two sets of locking members 22. The locking grooves 10 provide fixed insertion positions for the locking members 22, ensuring that the connecting sleeve 23 can be stably fixed on the column 1. The distance between the two sets of locking members 22 is consistent with the distance between adjacent locking grooves 10, ensuring that both locking members 22 can be simultaneously inserted into the two locking grooves 10, enhancing the stability of the connection. The locking members 22 penetrate the connecting sleeve 23 and are inserted into the locking grooves 10 on the column 1. Furthermore, it should be noted that the locking grooves 10 on the column 1 have an annular and intermittent structure, meaning they are distributed at multiple points along the circumference of the column 1. This ensures that when the connecting sleeve 23 rotates the support frame, the locking members 22 can also lock the position of the support frame. In this application, the locking component 22 is preferably a tightening screw, and the end of the tightening screw is provided with a rubber pad. The rubber pad improves the stability of the locking on the one hand, and avoids damage to the rod caused by excessive locking force on the other hand.

[0029] like Figure 4As shown, both the upper positioning universal ring 3 and the lower positioning universal ring 5 include a first circular plate 30, a first cavity 31 formed inside the first circular plate 30, a second circular plate 33 connected to the first cavity 31 via a rotating shaft 32, and a fixing hole 34 formed on the second circular plate 33. The first circular plate 30 is rotatably mounted on the upper support frame 2 and the lower support frame 4 via a rotating head 35. Specifically, the rotating head 35 is mounted on the first circular plate 30, and the inner rods on the upper support frame 2 and the lower support frame 4 are rotatably connected to the rotating head 35. There are many ways to make this rotatable connection, such as bearing connection, pin connection, and threaded connection. Furthermore, the rotation direction of the first circular plate 30 around the upper support frame 2 and the lower support frame 4 is 90° to the rotation direction of the second circular plate 33 around the first circular plate 30. The guide cylinder 6 passes through the fixing holes 34 of the upper positioning universal ring 3 and the lower positioning universal ring 5, respectively. The first circular plate 30 rotates around the axes of the upper support frame 2 and the lower support frame 4, providing adjustment in the first direction. This rotation can adjust the horizontal angle of the guide cylinder 6. The second circular plate 33 rotates around the pivot 32, with its rotation direction at 90° to that of the first circular plate 30, providing adjustment in the second direction. This rotation can adjust the vertical angle of the guide cylinder 6. Through the coordinated rotation of the first circular plate 30 and the second circular plate 33, the position and angle of the fixing hole 34 can be precisely adjusted, thus providing a precise positional basis for the installation of the guide cylinder 6.

[0030] like Figures 5 to 6 As shown, the guide cylinder 6 includes a hollow guide rod 60, an end 61 at the top of the guide rod 60, and a sliding cylinder 62 that slides along the guide rod 60. A locking element 22 is provided on the sliding cylinder 62. The end 61 is located on the upper positioning universal ring 3, and the sliding cylinder 62 is located on the lower positioning universal ring 5. The guide rod 60 passes through both the upper and lower positioning universal rings 3 and 5. The sliding cylinder 62 can be adjusted on the guide rod 60 according to the height change of the lower support frame 4. Once the position is determined, the sliding cylinder 62 is locked onto the guide rod 60 by the locking element 22. The locking element 22 is a screw or bolt.

[0031] To improve ease of operation, in this invention, the support column 1 is detachably connected to the hospital bed. There are many ways to achieve this detachable connection, such as fixing a cylindrical sleeve to the hospital bed and inserting the support column 1 directly into the sleeve; alternatively, a clamp can be used to hold the support column 1 to the hospital bed. Preferably, as shown below... Figure 7As shown in this application, a locking clamp 7 is provided at the lower end of the column 1, which locks the fixation frame onto the hospital bed. The locking clamp 7 includes a spring clamp with a first clamp 70 and a second clamp 71, and a locking member 22 disposed on the spring clamp. The locking member 22 passes through the first clamp 70 and locks onto the second clamp 71. Friction layers 73 are respectively provided on the clamping surfaces of the first clamp 70 and the second clamp 71. The locking member 22 is a screw or bolt. A hole is provided on the first clamp 70, and a threaded hole is provided on the second clamp 71 to engage with the bolt thread. When the bolt thread passes through the hole, it engages with the threaded hole to lock the frame. Additional pressure is applied by the locking member 22 to ensure a more secure connection between the clamp and the hospital bed.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
