Description

Technical Field

[0001] This invention relates to the medical field, and more particularly to a minimally invasive spinal puncture positioning device. Background Technology

[0002] Minimally invasive spinal surgery means avoiding large incisions while maintaining certain medical risks. It involves using tiny incisions or puncture channels, employing special instruments and devices, and completing the entire surgical process under visual guidance. The goal is to achieve smaller incisions, less tissue trauma, less bleeding, higher operational precision, more reliable results, and faster postoperative functional recovery compared to traditional or standard spinal surgery. Before the surgery, medical staff need to locate the puncture sites on the patient's back.

[0003] However, currently, the location of puncture sites in minimally invasive spinal surgery largely relies on the surgical experience of medical staff using X-ray fluoroscopy. Medical staff align and puncture based on visual observation of the skin around the patient's spine and the content displayed on the X-ray fluoroscopy instrument. This process is quite complex and prone to errors in puncture site location. Furthermore, during minimally invasive spinal puncture surgery, medical staff need to adjust the puncture needle at multiple angles. When errors occur in the angle adjustment, the puncture site may shift, resulting in inaccurate puncture site location. Summary of the Invention

[0004] In view of the shortcomings of current methods for locating puncture sites in minimally invasive spinal surgery, such as inconvenience in locating puncture sites from multiple angles and insufficient precision, the purpose of this invention is to provide a minimally invasive spinal puncture positioning device that can more conveniently locate puncture sites from multiple angles and achieve more accurate puncture site positioning.

[0005] The technical solution is as follows: A minimally invasive spinal puncture positioning device includes a lateral seat, slide rails, a sliding adjustment mechanism, a locking mechanism, and a rotation positioning mechanism.

[0009] Preferably, the device also includes a skin pressing mechanism, which is mounted on the positioning slider. The skin pressing mechanism includes a pressing plate, a transition spring, a slide rod, a fixing block, a support spring, and a pressure rod. The fixing block is fixedly connected to the positioning slider, and the pressure rod is slidably connected to the fixing block. A support spring connects the fixing block and the pressure rod. A slide rod is slidably connected to the pressure rod, and a pressing plate is fixedly connected to the end of the slide rod away from the pressure rod. A transition spring connects the pressure rod and the pressing plate.

[0010] Preferably, a spinal limiting mechanism is also included. The spinal limiting mechanism is set on the positioning slider. The spinal limiting mechanism includes a limiting pin, a limiting spring, a support block, a supporting limiting rod, and a horizontal bar. The supporting limiting rod is fixedly connected to the positioning slider. The support block is fixedly connected to the supporting limiting rod. Three limiting pins are slidably connected to the support block. The tops of the three limiting pins are connected to the support block with limiting springs. The horizontal bar is fixedly connected to one of the limiting pins.

[0011] Preferably, a support adjustment mechanism is also included. The support adjustment mechanism is mounted on the side seat and includes a support plate, an adjustment block, an adjustment rotation shaft, a fixed rod, a limiting bevel gear, an adjusting bevel gear, and a compression spring. The support plate is rotatably connected to the side seat. An adjustment block is fixedly connected to the bottom of the support plate. An adjustment rotation shaft is slidably connected to the middle of the adjustment block. An adjusting bevel gear is fixedly connected to the end of the adjustment rotation shaft away from the adjustment block.

The side of the sponge reclining mat away from the support plate is fixedly connected to the bottom of the sponge backrest.

[0013] The beneficial effects of this invention are: The patient lies on their side in a lateral decubitus seat. First, the medical staff holds the handle of the positioning platform and pushes the sliding positioning platform left and right, thereby moving the laser to the appropriate position. The medical staff then moves the positioning slider up and down, which in turn moves the laser to the appropriate position. Next, the medical staff rotates the angle adjustment protrusion, which rotates the laser to the appropriate angle, positioning the laser at the puncture site on the patient's back. The medical staff then rotates the magnetic support rod upward, causing the semicircular groove three on the rotating fixation plate to misalign with the semicircular grooves one and two on the rotating block. This facilitates the subsequent positioning of the puncture needle by the semicircular groove three on the rotating fixation plate and the semicircular grooves one and two on the rotating block, preventing the puncture needle from deviating. This allows the medical staff to more easily locate the puncture site on the patient's back and also allows for multi-angle adjustment of the laser, resulting in more precise positioning of the puncture site on the patient's back and providing a more accurate positioning for the puncture surgery.

[0014] When medical staff rotate the magnetic support rod upwards, the rotation of the magnetic support rod will cause the pressure rod to move, so that the pressure plate comes into contact with the skin of the patient's back. In this way, the pressure plate makes closer contact with the skin of the patient's back, thereby making the skin at the puncture site on the patient's back better spread out, and thus making the subsequent minimally invasive spinal puncture position more accurate.

[0015] When medical staff move the positioning slider up and down, the slider will move the limiting pins up and down to the appropriate position, so that the ends of the three limiting pins away from the support block are in contact with the patient's back. The limiting springs will be compressed, and one of the limiting pins will be inserted into the depression of the patient's spine. By observing the horizontal distance between the horizontal strip on one of the limiting pins and the other two limiting pins, the medical staff can judge whether the positioning of the limiting pins on the patient's spine is accurate. In this way, it is easier for medical staff to locate the puncture site on the patient's back, and the location of the puncture site can be more accurate. Attached Figure Description

The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here. Example 1

[0029] A minimally invasive spinal puncture positioning device, such as Figures 1-7As shown, it includes a side seat 1, a slide rail 2, a sliding adjustment mechanism, a locking mechanism, and a rotation positioning mechanism. The side seat 1 is connected to two slide rails 2 by rivets. The two slide rails 2 are symmetrically arranged. A sliding adjustment mechanism is provided between the two slide rails 2.

The positioning slider 33 is slidably connected to the sliding positioning platform 31. A limiting rubber block 34 is fixedly connected to the positioning slider 33. The limiting rubber block 34 and the sliding positioning platform 31... The sliding positioning table 31 has two fixing pins 38 connected by bolts. The two fixing pins 38 are symmetrically arranged. Each fixing pin 38 is slidably connected to a fixing rubber ring 39, which fits onto the fixing pin 38. A fixing strip 36 is fixedly connected between the two fixing rubber rings 39. Two compression rubber blocks 37 are fixedly connected to the fixing strip 36. The two compression rubber blocks 37 are symmetrically arranged. A positioning screw 35 is rotatably connected to the fixing strip 36. The positioning screw 35 and the threaded hole on the sliding positioning table 31 are on the same horizontal plane. The positioning screw 35 has a thread on the side near the threaded hole on the sliding positioning table 31.

[0031] The positioning mechanism includes a support bar 41, a rack 42, a spur gear 43, an angle rotation shaft 44, and a rubber sleeve 45. The support bar 41 is connected to the fixing bar 36 by rivets. The rack 42 is connected to the end of the support bar 41 away from the fixing bar 36 by rivets. The angle rotation shaft 44 is rotatably connected to the positioning slider 33. The rubber sleeve 45 is fixedly connected to the end of the angle rotation shaft 44 near the positioning slider 33. The rubber sleeve 45 is fitted on the angle rotation shaft 44 and contacts the positioning slider 33. The spur gear 43 is connected to the angle rotation shaft 44 by a flat key. The rack 42 and the spur gear 43 are located on the same horizontal plane.

[0032] The rotary positioning mechanism includes a rotating block 51, a rotating fixing plate 52, a rotating rod 53, an angle adjusting protrusion 54, a magnetic suction plate 55, a magnetic support rod 56, an iron pad 57, a sliding block 58, a fixing plate 59, and a laser 510. The rotating block 51 is bolted to one end of the angle rotation axis 44 away from the positioning slider 33. The rotating block 51 has two semi-circular grooves. The rotating fixing plate 52 is rotatably connected inside the rotating block 51. The rotating fixing plate 52 has a semi-circular groove 3. The rotating rod 53 is bolted to the rotating fixing plate 52 and slidably connected to the rotating block 51. Two angle adjusting protrusions 54 are bolted to the outside of the rotating block 51. The two angle adjusting protrusions 54 are symmetrically arranged. The rotating block 51 has a through-hole... A fixing plate 59 is connected by rivets. An iron pad 57 is connected to the fixing plate 59 by rivets. A magnetic suction piece 55 is connected to the fixing plate 59 by rivets. A magnetic support rod 56 is rotatably connected to the fixing plate 59. A short rod is provided on the magnetic support rod 56. The magnetic suction piece 55 and the magnetic support rod 56 have opposite magnetic properties and attract each other. A sliding block 58 is slidably connected to the fixing plate 59. The sliding block 58 has a long limiting groove and a short limiting groove. The short rod on the magnetic support rod 56 is slidably connected to the long limiting groove on the sliding block 58. The end of the rotating rod 53 away from the rotating fixing piece 52 is inserted into the short limiting groove on the sliding block 58. A laser 510 is connected to the magnetic support rod 56 by bolts.

[0033] The patient lies on their side in the lateral decubitus seat 1, with their back facing the sliding positioning platform 31. First, the medical staff holds the platform handle 32 and pushes the sliding positioning platform 31 left and right. This movement causes the two fixing pins 38 to move left and right, which in turn causes the fixing rubber ring 39, fixing strip 36, and positioning screw 35 to move left and right. The left and right movement of the sliding positioning platform 31 also causes the positioning slider 33, limiting rubber block 34, support strip 41, rack 42, and angle rotation shaft 44 to move left and right. The left and right movement of the angle rotation shaft 44 then causes the spur gear 43, rubber sleeve 45, rotating block 51, rotating fixing plate 52, rotating rod 53, angle adjusting protrusion 54, magnetic suction plate 55, magnetic support rod 56, iron pad 57, and sliding block to move left and right. 58. The fixing plate 59 and the laser 510 are moved left and right to the appropriate positions. Then, the medical staff moves the positioning slider 33 up and down. The up and down movement of the positioning slider 33 drives the limiting rubber block 34, support bar 41, rack 42, angle rotation shaft 44, spur gear 43, rubber sleeve 45, rotating block 51, rotating fixing plate 52, rotating rod 53, angle adjusting protrusion 54, magnetic suction plate 55, magnetic support rod 56, iron pad 57, sliding block 58, fixing plate 59 and laser 510 to the appropriate positions. Then, the medical staff rotates the angle adjusting protrusion 54. The rotation of the angle adjusting protrusion 54 drives the rotating block 51 to rotate. The rotation of the rotating block 51 drives the angle rotation shaft 44, spur gear 43, rubber sleeve 45, rotating fixing plate 52, rotating rod 53 to the appropriate positions. The adjustment protrusion 54, magnetic suction plate 55, magnetic support rod 56, iron pad 57, sliding block 58, fixing plate 59, and laser 510 are all rotated to the appropriate angle, so that the laser emitted by the laser 510 is aimed at the puncture site on the patient's back. Then, the medical staff pushes the fixing strip 36 towards the sliding positioning table 31, causing the fixing strip 36 to move the positioning screw 35 towards the threaded hole on the sliding positioning table 31, so that the thread on the positioning screw 35 contacts the threaded hole on the sliding positioning table 31. Then, the medical staff rotates the positioning screw 35, and the rotation of the positioning screw 35 causes the fixing strip 36 to continue moving towards the sliding positioning table 31. The fixing strip 36 will then contact the limiting rubber block 34, thereby limiting the rubber block 36. 4. The positioning slider 33 is limited. The fixing bar 36 moves towards the sliding positioning platform 31, causing the two compressed rubber blocks 37 to move towards the slide rail 2. The compressed rubber blocks 37 pass through the sliding positioning platform 31 and contact the slide rail 2, thus limiting the compression of the compressed rubber blocks 37 to the sliding positioning platform 31. At the same time, the fixing bar 36 moves towards the sliding positioning platform 31, and also causes the support bar 41 and rack 42 to move towards the sliding positioning platform 31, so that the rack 42 meshes with the spur gear 43, thereby limiting the rack 42 to the spur gear 43, and then limiting the rotating block 51, so that the rotating block 51 remains stationary after adjusting the angle. Then, the medical staff rotates the magnetic support rod 56 upwards.The magnetic support rod 56 rotates upward, causing the sliding block 58 to move upward. The upward movement of the sliding block 58 causes the rotating rod 53 to rotate upward, which in turn causes the rotating fixing plate 52 to rotate upward. This causes the semicircular groove three on the rotating fixing plate 52 to misalign with the semicircular groove one and semicircular groove two on the rotating block 51. This facilitates the subsequent positioning of the puncture needle by the semicircular groove three on the rotating fixing plate 52 and the semicircular groove one and semicircular groove two on the rotating block 51, preventing the puncture needle from deviating. This, in turn, facilitates more precise minimally invasive spinal puncture for the patient. The magnetic support rod 56 rotates upward... When the laser rotates upwards, it disengages from the magnetic suction plate 55. The upward rotation of the magnetic support rod 56 causes the laser 510 to rotate upwards as well. The magnetic support rod 56 then adheres to the iron pad 57, preventing it from moving and thus ensuring it doesn't obstruct subsequent procedures. This allows medical staff to more easily locate the puncture site on the patient's back and enables multi-angle adjustment of the laser 510, resulting in more precise positioning of the puncture site and facilitating more accurate subsequent surgical punctures.

[0034] After the surgery, medical staff rotate the magnetic support rod 56 downwards to reset it. This downward rotation of the magnetic support rod 56 causes the sliding block 58 to move downwards to reset. The downward movement of the sliding block 58 causes the rotating rod 53 to rotate downwards to reset, which in turn causes the rotating fixing plate 52 to rotate downwards to reset. The magnetic support rod 56 then disengages from the iron pad 57 and re-attracts to the magnetic suction plate 55. The downward rotation of the magnetic support rod 56 causes the laser 510 to rotate downwards to reset. Medical staff then rotate the magnetic support rod 56 downwards again, disengaging it from the iron pad 57. The magnetic support rod 56 will... Attracted by the magnetic suction plate 55, the magnetic support rod 56 rotates downward to reset, causing the laser 510 to rotate downward to reset. Then, the medical staff rotates the positioning screw 35 in the opposite direction, causing the positioning screw 35 to disengage from the threaded hole on the sliding positioning table 31. Then, the medical staff pulls the fixing bar 36 to move it away from the sliding positioning table 31 to reset. This causes the fixing bar 36 to move the positioning screw 35, the compressed rubber block 37, the fixing pin 38, the fixing rubber ring 39, the support bar 41, and the rack 42 away from the sliding positioning table 31 to reset. The rack 42 disengages from the spur gear 43 and no longer meshes with it, so that the rack 42 no longer limits the spur gear 43. Example 2

[0035] Based on Example 1, such as Figures 8-9As shown, it also includes a skin pressing mechanism, which is mounted on the positioning slider 33. The skin pressing mechanism includes a pressing plate 61, a transition spring 62, a slide rod 63, a fixing block 64, a support spring 65, and a pressure rod 66. The fixing block 64 is connected to the positioning slider 33 by rivets. The pressure rod 66 is slidably connected to the fixing block 64. The support spring 65 is connected between the fixing block 64 and the pressure rod 66 by a hook. The slide rod 63 is slidably connected to the pressure rod 66. The end of the slide rod 63 away from the pressure rod 66 is connected to the pressing plate 61 by rivets. The transition spring 62 is connected between the pressure rod 66 and the pressing plate 61 by a hook.

[0036] When medical staff rotate the magnetic support rod 56 upwards, the rotation of the magnetic support rod 56 will drive the pressure rod 66, compressing the support spring 65. The movement of the pressure rod 66 will cause the slide rod 63 to move away from the fixed block 64. The movement of the slide rod 63 away from the fixed block 64 will cause the clamping plate 61 to move away from the fixed block 64. The clamping plate 61 will then contact the skin of the patient's back, compressing the transition spring 62. This will make the clamping plate 61 contact the skin of the patient's back more tightly, thus ensuring the skin at the puncture site on the patient's back is more secure. This allows for better deployment, leading to more precise placement of the subsequent minimally invasive spinal puncture on the patient. After the surgery, medical staff rotate the magnetic support rod 56 downwards, causing the magnetic support rod 56, laser 510, and pressure rod 66 to disengage. The support spring 65 then resets, causing the pressure rod 66 to move upwards and reset. The transition spring 62 then resets, causing the clamping plate 61 to move closer to the laser 510 and reset, which in turn causes the clamping plate 61 to move the slide rod 63 closer to the laser 510. Example 3

[0037] Based on Example 2, such as Figure 9 As shown, it also includes a spinal limiting mechanism, which is mounted on the positioning slider 33. The spinal limiting mechanism includes limiting pins 71, limiting springs 72, support blocks 73, supporting limiting rods 74, and horizontal bars 75. The supporting limiting rods 74 are connected to the positioning slider 33 by rivets, and the supporting blocks 73 are connected to the supporting limiting rods 74 by rivets. Three limiting pins 71 are slidably connected to the supporting blocks 73. The tops of the three limiting pins 71 are connected to the supporting blocks 73 by hooks, and the horizontal bars 75 are connected to one of the limiting pins 71 by rivets.

[0038] When medical staff move the positioning slider 33 up and down, the positioning slider 33 will drive the support limiting rod 74, support block 73, limiting nail 71, limiting spring 72 and horizontal bar 75 to move up and down to the appropriate position. The ends of the three limiting nails 71 away from the support block 73 are in contact with the patient's spine. The limiting spring 72 will be compressed, and one of the limiting nails 71 will be stuck in the depression of the patient's spine, so that the positions of the three limiting nails 71 are not consistent. By observing the horizontal distance between the horizontal bar 75 on one of the limiting nails 71 and the other two limiting nails 71, the medical staff can judge whether the positioning of the limiting nail 71 on the patient's spine is accurate. After the operation, the patient is no longer in contact with the limiting nail 71, the limiting spring 72 returns to its original position, and the return of the limiting spring 72 drives the limiting nail 71 to its original position. In this way, the puncture needle can be positioned more accurately. Example 4

[0039] Based on Example 3, such as Figure 10 As shown, it also includes a support adjustment mechanism, which is set on the side seat (1). The support adjustment mechanism includes a support plate 81, an adjustment block 82, an adjustment rotation shaft 83, a fixing rod 84, a limiting bevel gear 85, an adjusting bevel gear 86, and a compression spring 87. The support plate 81 is rotatably connected to the side seat 1. The support plate 81 has an arc-shaped surface on the side near the sliding positioning table 31. The bottom of the support plate 81 is connected to the adjustment block 82 by rivets. The adjustment rotation shaft 83 is slidably connected to the middle of the adjustment block 82. The adjustment rotation shaft 83 is located away from the adjustment block. One end of 82 is bolted to an adjusting bevel gear 86. A compression spring 87 is connected to the side of the adjusting bevel gear 86 away from the adjusting rotation shaft 83 via a hook. The end of the compression spring 87 away from the adjusting bevel gear 86 is connected to the side seat 1. A fixing rod 84 is bolted to the side of the side seat 1 near the adjusting block 82. A limiting bevel gear 85 is riveted to the end of the fixing rod 84 away from the side seat 1. The adjusting bevel gear 86 meshes with the limiting bevel gear 85. The limiting bevel gear 85 is rotatably connected to the adjusting rotation shaft 83.

[0040] When the patient lies on their side in the side-lying seat 1, the medical staff pushes the adjusting rotation shaft 83 towards the side-lying seat 1. The adjusting rotation shaft 83 drives the adjusting bevel gear 86 towards the side-lying seat 1. The adjusting bevel gear 86 disengages from the limiting bevel gear 85, and the compression spring 87 is compressed. Then, the medical staff adjusts the support plate 81 to swing towards the sliding positioning table 31. The swing of the support plate 81 towards the sliding positioning table 31 drives the adjusting block 82 to rotate. The rotation of the adjusting block 82 drives the adjusting rotation shaft 83 to rotate. The rotation drives the adjusting bevel gear 86 to rotate, which twists the compression spring 87, bringing the support plate 81 into contact with the patient. Then, the medical staff releases the adjusting rotation shaft 83, and the compression spring 87 returns to its original position. The return of the compression spring 87 drives the adjusting bevel gear 86 to move away from the lateral decubitus seat 1 and reset. The adjusting bevel gear 86 re-engages with the limiting bevel gear 85, and the movement of the adjusting bevel gear 86 to reset drives the adjusting rotation shaft 83 to move away from the lateral decubitus seat 1 and reset. In this way, the patient's lateral decubitus position can be better supported, making the patient more stable during the operation. Example 5

[0041] Based on Example 4, such as Figures 10-11 As shown, it also includes a sponge backrest 91 and a sponge reclining cushion 92.
