Description

Technical Field

[0001] This utility model relates to the technical field of CT lumbar disc puncture equipment, and in particular to a CT lumbar disc minimally invasive puncture positioning device. Background Technology

[0002] Minimally invasive lumbar disc herniation surgery is a new treatment method that utilizes modern high-tech surgical equipment and methods to treat lumbar disc herniation with minimal trauma, minimizing the probability of infection. It is characterized by minimal trauma, less pain, and better results. During CT-guided lumbar disc puncture, a positioning device is used to locate the puncture needle and catheter, ensuring accurate insertion into the body.

[0003] To position the puncture needle and catheter, positioning devices typically use a positioning frame to mount the puncture needle. During use, the position and angle of the puncture needle on the positioning frame are adjusted to regulate the intervention angle and position of the puncture needle and catheter, ensuring accurate insertion into the patient's body. However, traditional positioning frames are rectangular and do not conform to the shape of the patient's lumbar spine, resulting in a long axial distance between the fixing point and the puncture point of the puncture needle. This makes it difficult to control the puncture accuracy. Furthermore, while traditional puncture needles are movable, their inherent structure prevents effective rotation, hindering adjustments to the puncture orientation of the needle and catheter according to needs. This leads to complex adjustments during surgery, significantly impacting the efficiency of medical personnel.

[0004] Based on this, the present invention proposes a CT-guided minimally invasive lumbar disc puncture and positioning device to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide a CT lumbar disc minimally invasive puncture positioning device to solve the problems of long puncture axis, low accuracy and inconvenience in adjusting the puncture angle in the existing technology.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A CT-guided minimally invasive lumbar disc puncture and positioning device includes:

[0008] The mounting bracket is an arc-shaped support, and rollers are provided on both sides of the bottom of the mounting bracket;

[0009] The positioning mechanism is located on one side of the mounting frame and includes an arc-shaped slide groove that is formed on the mounting frame and is interconnected. A slider is slidably disposed in the slide groove. A mounting block is provided at one end of the slider, and a limit component is provided at the other end of the slider.

[0010] In a preferred embodiment, the positioning mechanism further includes two clamping plates slidably disposed on one side of the mounting block, a sliding block disposed on one side of the clamping plate, the sliding block being slidably connected to the mounting block, and a bidirectional lead screw being rotatably connected to the mounting block, the bidirectional lead screw being threadedly connected to both sliding blocks.

[0011] In a preferred embodiment, a protective plate is also provided inside the clamping plate.

[0012] In a preferred embodiment, a support frame is rotatably connected to the top of the mounting block, and a calibration light is provided on one side of the support frame.

[0013] In a preferred embodiment, electric push rods are provided on both sides of the bottom of the mounting bracket.

[0014] In a preferred embodiment, the limiting component includes a limiting block slidably connected within the slider, a spring telescopic rod is provided between the limiting block and the slider, one end of the limiting block is fixedly connected to a pull rod, and one end of the pull rod passes through the slide groove and extends to the outside of the mounting bracket.

[0015] In a preferred embodiment, a fixing bolt is threaded onto one side of the slider surface. The fixing bolt is slidably connected to a groove on the mounting bracket, and a washer is fitted between one end of the fixing bolt and the mounting bracket.

[0016] In a preferred embodiment, a limiting plate is further provided at one end of the slider, and a connecting post is provided on the limiting plate. The connecting post matches the connecting groove opened at the end of the mounting block, and a spring is provided in the connecting groove.

[0017] In a preferred embodiment, one end of the spring is connected to the connecting post, and the other end is connected to the bottom wall of the connecting groove.

[0018] In a preferred embodiment, a plurality of limiting protrusions are provided on one end face of the limiting disk near the mounting block, and the limiting protrusions match the limiting slots provided on the end face of the mounting block.

[0019] Compared with the prior art, this utility model provides a CT-guided minimally invasive lumbar disc puncture and positioning device, which has the following beneficial effects:

[0020] 1. By setting an arc-shaped mounting bracket, it can match the shape of the human waist during use, thereby reducing the needle travel distance and effectively ensuring puncture accuracy.

[0021] 3. By setting up a positioning mechanism, during CT minimally invasive lumbar disc puncture, the slider at one end of the mounting block is circular, and the groove on the mounting frame is arc-shaped. The slider and the groove cooperate to move the mounting block and adjust the position of the device. Two clamps on one side of the mounting block can clamp and position the instruments for CT minimally invasive lumbar disc puncture. The bidirectional screw and the sliding block cooperate to move the two clamps to one side simultaneously to install and fix the puncture needle and catheter. The protective plate inside the clamp can protect the puncture needle and catheter and prevent the clamp from causing wear to the puncture needle and catheter during use. The laser emitted by the calibration lamp is located at the center of the two clamps. The device can be positioned by aligning the calibration lamp with the marking points on the patient. The support frame on the calibration lamp can rotate 90 degrees, allowing for quick use and storage. It can quickly adjust and position the puncture needle and catheter for CT minimally invasive lumbar disc puncture, effectively improving the positioning effect of the device.

[0022] 3. By setting a limiting component, during CT minimally invasive lumbar disc puncture, the limiting block inside the slider can rub against the inner wall of the groove to fix the position of the mounting block and improve its stability. The spring telescopic rod supports the limiting block, improving its performance. The pull rod can control the position of the limiting block, facilitating the adjustment and sliding of the slider. The fixing bolt cooperates with the slider and clamps the mounting frame with a washer, fixing the slider in place. This allows for quick adjustment of the positioning device's position, improving its adjustment effect.

[0023] 4. The setting of the limiting plate and spring makes it easy to adjust the direction of the support frame on the mounting block according to the puncture requirements during use, so as to meet the puncture requirements of different angles. It is simple and convenient to use and adjust; it solves the problems of long puncture axis, low accuracy and inconvenience in adjusting the puncture angle in the existing technology.

[0038] As per the instruction manual Figures 1-6 As shown, this utility model provides a technical solution:

[0039] A CT-guided minimally invasive lumbar disc puncture positioning device includes a mounting frame 1 and a positioning mechanism 3; wherein:

[0040] The mounting frame 1 is a movable arc-shaped support, and two rollers 2 are fixedly installed on both sides of the bottom of the mounting frame 1 to facilitate the movement of the mounting frame 1;

[0041] The positioning mechanism 3 is movably installed on one side of the mounting frame 1 and is used to position and fix the CT lumbar disc puncture needle and catheter. It includes an arc-shaped sliding groove 31 that is opened on the mounting frame 1 and interconnected with each other. A slider 32 is slidably connected in the sliding groove 31. One end of the slider 32 is connected to a mounting block 33, and a limit component 311 is provided at the other end of the slider 32.

[0042] It should be noted that, in this embodiment, the mounting frame 1 is designed to facilitate its placement on the upper side of the lumbar spine during use. The insertion positions of the puncture needle and catheter are adjusted by moving the mounting frame 1. The slider 32 is slidable within the groove 31 to adjust its position on the mounting frame 1, thereby adjusting the insertion direction of the puncture needle and catheter. The limiting component 311 positions the slider 32 within the groove 31 to facilitate precise positioning of the needle insertion position and direction. Specifically, during use: first, the mounting frame 1 is moved to the upper side of the lumbar spine by rotating the roller 2, and then the mounting frame 1 is fixed. After the mounting frame 1 is fixed, the position of the slider 32 within the groove 31 is adjusted. Once the position of the slider 32 within the groove 31 is adjusted, the limiting component 311 is used to fix the slider 32. After fixation, acupuncture treatment is performed on the patient's lumbar disc herniation.

[0043] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, the positioning mechanism 3 further includes two clamping plates 34 slidably connected to one side of the mounting block 33. A sliding block 35 is fixedly connected to one side of the clamping plate 34. The sliding block 35 is slidably connected inside the mounting block 33, and a bidirectional lead screw 36 is rotatably connected inside the mounting block 33. Both ends of the bidirectional lead screw 36 are threadedly connected to the two sliding blocks 35.

[0044] It should be noted that in this embodiment, the aforementioned clamping plate 34, sliding block 35, and bidirectional screw 36 form a clamping structure that facilitates the clamping of the puncture needle. Specifically, during UICT lumbar disc minimally invasive puncture, the mounting block 33 can slide within the mounting frame 1 through the cooperation of the slider 32 and the sliding groove 31, and its position can be quickly adjusted; then, the bidirectional screw 36 is threadedly connected to the sliding block 35 on one side of the two clamping plates 34, which can simultaneously drive the two clamping plates 34 to move from both ends to the middle to clamp the puncture needle or catheter, allowing for rapid adjustment and positioning of the puncture needle and catheter for CT lumbar disc minimally invasive puncture.

[0045] Specifically, a protective plate 37 is fixedly connected to the inner wall of the clamping plate 34. When clamping, the protective plate 37 is used to protect the puncture needle or catheter to avoid injury to the puncture needle or catheter.

[0046] Specifically, a support frame 38 is rotatably connected to the top of the mounting block 33, and a calibration light 39 is fixedly connected to one side of the support frame 38. Electric push rods 310 are provided on both sides of the bottom of the mounting frame 1. In use, the position of the device is adjusted and aligned by aligning the calibration light 39 with the marking point on the patient to improve the accuracy of the device. The support frame 38 can only rotate at a right angle of 90 degrees, and the calibration light 39 can be opened and stored when not in use.

[0047] As a preferred embodiment, such as Figure 4 As shown, the limiting component 311 includes a limiting block 3111 slidably connected to one end of the inner wall of the slider 32. A spring telescopic rod 3112 is fixedly connected between the limiting block 3111 and the slider 32. A pull rod 3113 is fixedly connected to one end of the limiting block 3111. One end of the pull rod 3113 extends through to the outer wall of the mounting frame 1. A fixing bolt 3114 is threadedly connected to one side of the surface of the slider 32. The fixing bolt 3114 is slidably connected to the outer wall of the mounting frame 1. A washer 3115 is sleeved between one end of the fixing bolt 3114 and the mounting frame 1.

[0048] It should be noted that, in this embodiment, when performing minimally invasive puncture on the CT lumbar intervertebral disc, the position of the mounting block 33 can be quickly adjusted and fixed by pressing the pull rod 3113 to control the contact friction between the limiting block 3111 and the slide groove 31. The spring telescopic rod 3112 can provide stable support for the limiting block 3111. The fixing bolt 3114 is clamped to the mounting frame 1 through the washer 3115. The sliding block 32 is limited by the force. Both the pull rod 3113 and the fixing bolt 3114 are slidably connected to the slide groove 31, which allows for rapid adjustment of the position of the positioning device.

[0049] As a preferred embodiment, such as Figure 3 , Figure 5 and Figure 6 As shown, a limiting disk 312 is also installed at one end of the slider 32. A connecting post 313 is provided on the limiting disk 312. The connecting post 313 matches the connecting groove 3311 opened at the end of the mounting block 33. A spring 314 is installed in the connecting groove 3311. One end of the spring 314 is connected to the connecting post 313, and the other end is connected to the bottom wall of the connecting groove 3311.

[0050] It should be noted that in this embodiment, the connection between the limiting plate 312 and the mounting block 33 is achieved by inserting the connecting post 313 into the connecting groove 3311. Furthermore, a plurality of limiting protrusions 315 are provided on the end face of the limiting plate 312 near the mounting block 33. These limiting protrusions 315 match the limiting slots 316 provided on the end face of the mounting block 33. During use, the interaction between the limiting protrusions 315 and the limiting slots 316 limits the mounting block 33, preventing it from rotating. Simultaneously, after rotating the mounting block 33, the interaction between the limiting protrusions 315 and the limiting slots 316 further limits its position, allowing medical personnel to adjust the intervention direction of the puncture needle according to usage requirements.

[0051] When the CT lumbar disc minimally invasive puncture positioning device of this utility model is used, the controller drives one end of the electric push rod 310 to move downward to limit and support the mounting frame 1, thereby limiting the position of the device. Then, by manually pressing the pull rod 3113, the limiting block 3111 moves to one end to release the restriction on the slider 32. The slider 32 cooperates with the slide groove 31 to move the mounting block 33. By manually rotating the support frame 38, the calibration lamp 39 rotates to one side. The light emitted by the calibration lamp 39 coincides with the marking point on the patient to limit the device. The pull rod 3113 is released, and the spring telescopic rod 3112 supports the limiting block 3111 so that it contacts the slide groove 31 to limit the mounting block 33. The fixing bolt 3114 is manually rotated and threaded to the slider 32, which drives the gasket 3115 to cooperate with the mounting frame 1 to fix it. The bidirectional screw 36 is manually rotated. The two ends of the bidirectional screw 36 cooperate with the two sliding blocks 35 to drive the two clamps 34 to move towards the middle at the same time to fix the puncture needle and catheter. At the same time, during use, the mounting block 33 is manually rotated according to the puncture direction of the puncture needle and catheter to make precise adjustments to the puncture direction.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
