[0049] EMBODIMENT

[0050] Reference Figure 1 and Figure 2 The spinal puncture body position auxiliary device in the illustration is a specific embodiment of the present application, specifically including a puncture bed 11, a base 2, a first cantilever 3, an abdominal positioning throw pillow 4, a second cantilever 5, a shoulder positioning support 6, a third cantilever 7, and a lower limb positioning support 8, wherein the puncture bed 11 is provided with a mattress 12 and a pillow 13 to improve the comfort of the puncture patient, the abdominal positioning throw pillow 4, the shoulder positioning support 6, and the lower limb positioning support 8 are respectively connected with the base 2 on one side of the puncture bed 11 through the first cantilever 3, the second cantilever 5, and the third cantilever 7, and the puncture patient lies on the side of the mattress 12 of the puncture bed facing the side where the base is located, wherein the abdominal positioning throw pillow 4 tightly abuts against the chest and abdomen of the puncture patient, the shoulder positioning support 6 pushes the two sides of the puncture patient's shoulders from behind to the front, and the lower limb positioning support 8 fixes the puncture patient's lower limbs in a curled state, so as to ensure that the puncture patient's back spine is in a puncture body position of forward bending, and the other side of the puncture bed facing the back of the puncture patient forms a puncture operation area 100, and a doctor performs spinal puncture operation on the puncture patient in the puncture operation area 100, and the puncture bed on one side of the area is not provided with a connecting mechanism and will not hinder the puncture operation.

[0051] Specifically, the abdominal positioning throw pillow 4 is liftable and connectable with the base 2 through the first cantilever 3, and the patient lying on the side of the puncture bed tightly abuts the chest and abdomen with the abdominal positioning throw pillow, which is the body position positioning reference of the puncture patient.

[0052] As Figure 3 and Figure 4As shown, the base 2 is provided with a base sleeve 21, a fixing seat 22, a lifting screw 23, a lifting nut seat 24, a bearing seat 25 and a force rod 26. The base sleeve 21 is in a cylindrical structure and is vertically arranged. The bottom of the base sleeve 21 is fixed to one side of the bed body of the puncture bed 11 through the fixing seat 22 with a flange structure. The flange structure of the fixing seat 22 is provided with a base fixing hole 201. The base fixing hole is fixed to the threaded hole of the bed body through a bolt.

[0053] The abdominal positioning pillow 4 in the embodiment is connected to the base through the first cantilever 3. The lifting structure is as follows: the lifting screw 23 is assembled in the base sleeve 21. The bearing seat 25 is assembled at the top and bottom of the base sleeve 21 for the rotation assembly of the lifting screw 23. The lifting screw 23 has only the rotation freedom in the base sleeve 21. The top of the lifting screw 23 extends out of the base sleeve 21 and is provided with the force rod 26 for facilitating the rotation of the lifting screw 23. The lifting nut seat 24 is sleeved on the lifting screw 23 through the thread cooperation. Meanwhile, the guide groove is arranged on the base sleeve 21 in the axial direction. The limiting pin is arranged on the lifting nut seat 24 and is inserted into the guide groove of the base sleeve. The rotation freedom of the lifting nut seat 24 is limited through the guide groove. In this way, after the rotation of the lifting screw 23, the lifting nut seat 24 can only slide in the axial direction of the base sleeve.

[0054] For reference Figure 5 The cantilever connecting sleeve 31 is arranged at one end of the first cantilever 3 and is sleeved on the base sleeve 21 in a sliding mode. The positioning clamping groove 311 is arranged at the bottom of the cantilever connecting sleeve 31. After the cantilever connecting sleeve 31 is sleeved on the base sleeve 21, the bottom is embedded with the limiting pin of the lifting nut seat 24 extending out of the guide groove of the sleeve base. The limiting pin of the lifting nut seat 24 can limit the axial position of the cantilever connecting sleeve 31 on the base sleeve 21 and can also limit the rotation of the cantilever connecting sleeve 31 around the base sleeve. When the lifting screw 23 is rotated to drive the lifting nut seat 24 to move, the cantilever connecting sleeve 31 and the first cantilever 3 are driven to move relative to the base. The height position of the abdominal positioning pillow 4 connected to the first cantilever is adjusted to adapt to the puncture patients with different body sizes.

[0055] The soft pillow fabric is arranged outside the pillow support 41 of the abdominal positioning pillow 4. The pillow support 41 is fixedly connected to the other end of the first cantilever 3 through the pillow fixing bolt 42.

[0056] The shoulder positioning support 6 is connected to the first cantilever 3 through the second cantilever 5, and is arranged to be lifted together with the abdominal positioning bolster 4. Since the shoulder of a human body is symmetrically arranged relative to the spine of the chest and abdomen, the height position of the shoulder positioning support 6 does not need to be adjusted separately after the position of the abdominal positioning bolster 4 is set. The second cantilever 5 adopts a two-section arm support structure, and the shoulder positioning support 6 is arranged to pass over the patient from the back to push the shoulder of the patient forward, so that the spine of the back is formed into forward flexion.

[0057] Specifically as shown in Figure 5 and Figure 6 The second cantilever 5 includes a first fixed arm support 51, a first swing arm support 52, a hinge shaft 53, a swing angle adjusting arc 54, a swing angle positioning pin 55 and a pin shaft 56. The first fixed arm support 51 and the first swing arm support 52 are hingedly connected through the hinge shaft 53 to form an inverted U-shaped arm support structure, which facilitates the arrangement of the shoulder positioning support 6 from above the patient in lateral position to the back of the patient. One end of the first fixed arm support 51 is fixedly connected to the first cantilever 3 through a first fixed arm support seat 511, and the other end is obliquely upwardly bent and hingedly connected to the first swing arm support 52. The second swing arm support 52 is downwardly bent and hingedly connected to the cantilever hinge seat 61 of the shoulder positioning support 6 through the pin shaft 56.

[0058] In the second cantilever 5, the first fixed arm support 51 is fixed to the first cantilever 3, and the first swing arm support 52 swings relative to the first fixed arm support 51 about the hinge shaft 53. During the lying of the patient, the shoulder positioning support 6 is swung away to leave a space for the movement of the patient. In addition, after the shoulder of the patient is positioned, the first swing arm support 52 is locked. Therefore, the swing angle positioning mechanism is further arranged between the first fixed arm support 51 and the first swing arm support 52.

[0059] The swing angle positioning mechanism on the second cantilever 5 includes the swing angle adjusting arc 54 fixed to the first swing arm support 52. The swing angle adjusting arc 54 is a right circular arc with the swing hinge point of the first swing arm support 52 as the center and is parallel to the swing plane of the first swing arm support 52. A swing angle adjusting hole 512 is arranged at the position where the swing angle adjusting arc 54 and the first fixed arm support 51 swing relative to each other, and the swing angle adjusting arc 54 passes through the swing angle adjusting hole 512. The swing angle positioning pin 55 is arranged to be inserted into the swing angle adjusting hole 512 from the side surface of the swing angle adjusting hole 512. The swing angle adjusting arc 54 is inserted into the swing angle adjusting hole 512 as the first swing arm support 52 swings. After the first swing arm support 52 is swung to the position, the swing angle positioning pin 55 is used to tightly lock the swing angle adjusting arc 54 in the swing angle adjusting hole 512 to lock the first swing arm support 52. The swing angle positioning pin 55 can adopt a threaded assembly structure or a structure that uses a spring to tightly align the positioning groove on the swing angle adjusting arc.

[0060] The shoulder positioning support 6 in the embodiment realizes the positioning of the shoulder, which includes adapting the width between the two shoulders and pushing the shoulder forward.

[0061] Referring to Figure 7 and Figure 8 , the shoulder positioning support 6 in the embodiment includes a cantilever hinge base 61, a guide rod 62, a shoulder positioning fork 63, a telescopic adjusting mechanism 64 and a width adjusting mechanism 65. The cantilever hinge base 61 is hinged to the end of the first swing arm frame of the second cantilever 5 through the pin shaft 56, and a locking pin is arranged on the cantilever hinge base 61 to stop the pin shaft. The guide rod 62 is arranged on the cantilever hinge base 61, and the shoulder positioning fork 63 is installed at the front end of the guide rod 62. The shoulder positioning fork 63 includes two groups of fork bodies corresponding to the shoulders of the patient on both sides, and the fork bodies are wrapped with soft cushioning materials such as sponge.

[0062] In order to keep the shoulders of the puncture patient pushed forward by the shoulder positioning support 6, the guide rod 62 in the embodiment is slidingly assembled on the cantilever hinge base 61, and a guide hole is processed on the cantilever hinge base 61 for the transmission and insertion of the guide rod 62. The telescopic adjusting mechanism 64 is arranged between the guide rod 62 and the cantilever hinge base 61 to control the sliding and positioning of the guide rod 62 and the shoulder positioning fork 63 arranged at the front end of the guide rod 62. Specifically, the telescopic adjusting mechanism 64 includes a telescopic adjusting screw 641, a telescopic connecting rod 642 and a telescopic adjusting nut 643. The telescopic adjusting screw 641 is rotationally assembled perpendicular to the guide rod 62, and a hand wheel is processed at the end of the telescopic adjusting screw 641 to facilitate the rotation of the screw. A through groove is processed on the guide rod 62, and the other end of the telescopic adjusting screw 641 is rotationally assembled in the through groove through a shaft shoulder. The shaft shoulder restricts the axial movement degree of freedom of the screw. The telescopic adjusting screw 641 can be transversely moved along the through groove while being rotated. The telescopic adjusting nut 643 is sleeved on the telescopic adjusting screw 641 through thread cooperation. Connection ears are arranged on both sides of the telescopic adjusting nut 643. The connection ears on both sides of the telescopic adjusting nut 643 are connected with the cantilever hinge base 61 and the guide rod 62 through the telescopic connecting rod 642. The ends of the telescopic connecting rod 642 are respectively hinged with the connection ears of the telescopic adjusting nut and the guide rod or the cantilever hinge base. The telescopic connecting rod 642 restricts the rotation degree of freedom of the telescopic adjusting nut 643. When the telescopic adjusting screw 641 is rotated, the telescopic adjusting nut 643 can only slide along the axial direction of the screw under the thread transmission action, and then drives the guide rod 62 to slide back and forth along the axial direction relative to the cantilever hinge base through the telescopic connecting rod 642, thereby pushing the shoulder positioning fork at the front end of the guide rod to push the puncture patient. After the shoulder positioning fork pushes the shoulder of the puncture patient to the position, the rotation of the telescopic adjusting screw 641 is stopped. Through the self-locking performance of the thread transmission between the screw and the nut, the positioning of the shoulder positioning fork to the shoulder of the puncture patient can be maintained.

[0063] In order to adjust the width between the two groups of shoulder positioning forks 63 of the shoulder positioning support 6 to adapt to the shoulder width of patients of different sizes, the width adjustment mechanism 65 is arranged between the two groups of shoulder positioning forks 63 of the embodiment, which adjusts the transverse width between the shoulder positioning forks 63. Specifically, the width adjustment mechanism 65 includes a parallelogram connecting rod 651, a transverse adjustment nut 652, a transverse adjustment sleeve 653, and a transverse adjustment connecting rod 654. The two groups of fork bodies of the shoulder positioning forks 63 are respectively connected to the two sides of the front end of the guide rod 62 through the parallelogram connecting rods 651. The two groups of shoulder positioning forks 63 are respectively arranged symmetrically on the two sides of the front end of the guide rod 62 through the parallelogram connecting rods 651. The parallelogram connecting rods 651 enable the two groups of shoulder positioning forks 63 to translate relative to each other to adjust the distance therebetween. A threaded section 621 is arranged on the guide rod 62 behind the parallelogram connecting rods 651. The transverse adjustment nut 652 is sleeved on the threaded section 621 through threaded cooperation. The transverse adjustment nut 652 is axially movable along the guide rod by rotating the transverse adjustment nut 652 under the threaded transmission cooperation of the threaded section 621. The transverse adjustment sleeve 653 is sleeved on the transverse adjustment nut 652 and can rotate relative to the transverse adjustment nut 652. The connecting ears arranged on the two sides of the transverse adjustment sleeve 653 are connected to the transverse adjustment connecting rod 654. The transverse adjustment sleeve 653 is connected to the parallelogram connecting rods 651 corresponding to the two groups of fork bodies through the transverse adjustment connecting rod 654. The transverse adjustment connecting rod 654 limits the rotation of the transverse adjustment sleeve together with the transverse adjustment nut. Rotating the transverse adjustment nut 652 on the guide rod slides, and the parallelogram connecting rods are pushed and pulled through the transverse adjustment sleeve 653 and the transverse adjustment connecting rod 654, so that the two groups of shoulder positioning forks 63 are synchronously and relatively translated, and the distance between the two groups of shoulder positioning forks 63 is adjusted.

[0064] With reference to Figure 1 and Figure 9 The lower limb positioning support 8 is connected to the base 2 from the side through the third cantilever 7, and the lower limbs of the patient are fixed in a curled state through the lower limb stopper 85 on the lower limb positioning support 8.

[0065] The third cantilever 7 comprises a second fixed arm support 71, a second swing arm support 72, a second fixed arm support seat 73, hinge shafts 74 and 75, and a first swing angle support 76 and a second swing angle support 77. The second fixed arm support 71 and the second swing arm support 72 are hingedly connected to form a two-stage arm support structure of the third cantilever 7. The second fixed arm support 71 is fixedly connected to the cantilever mounting hole on the side of the base through the second fixed arm support seat 73. The second swing arm support 72 is hingedly connected to the other end of the second fixed arm support 71 through the hinge shaft 74. The support assembly plate of the lower limb positioning support 8 is hingedly connected to the end of the second swing arm support 72 through the hinge shaft 75. The first swing angle support 71 is arranged between the second fixed arm support 71 and the second swing arm support 72 as a swing angle positioning mechanism of the third cantilever 7. The second swing angle support 72 is arranged between the second swing arm support 72 and the lower limb positioning support 8. As shown in Figure 10 , the positioning and adjustment of the lower limb positioning support 8 on the lower limb of the puncture patient are adjusted by adjusting the swing angle of the third cantilever and the swing angle of the lower limb positioning support 8.

[0066] The first swing angle support 76 and the second swing angle support 77 are the same in structure. The first swing angle support 76 is taken as an example for detailed description.

[0067] Referring to Figure 11 , the first swing angle support 76 comprises a positioning rod 761, a sleeve rod 762, a fixed hinge seat 763, a hinge sleeve 764, a locking screw 765, and a force rod 766. The positioning rod 761 is slidingly inserted into the sleeve rod 762 with two open ends to form the telescopic rod main structure of the first swing angle support. The positioning rod 761 is hingedly connected to the second fixed arm support 71 through the fixed hinge seat 763. The sleeve rod 762 is hingedly connected to the second swing arm support 72 through the hinge sleeve 764. The locking screw 765 is arranged on the sleeve rod 762 through a threaded hole seat and is inserted into the sleeve rod 762 perpendicularly to the positioning rod 761. The force rod 766 is arranged on the outer end of the locking screw 765 to facilitate the rotation of the locking screw. The locking screw 765 is loosened, and the positioning rod 761 can slide back and forth in the sleeve rod 762 with the swing of the second swing arm support. After the swing angle of the second swing arm support is adjusted, the locking screw 765 is tightened to tightly lock the positioning rod 761 in the sleeve rod 762, thereby achieving the locking and positioning of the second swing arm support.

[0068] The structure of the second swing angle support 77 is similar to that of the first swing angle support 76, which is not described herein. In addition, in actual application, the first swing angle support used on the third cantilever 7 as a swing angle positioning mechanism can be designed to replace the swing angle adjusting arc structure used on the second cantilever 5.

[0069] Referring to Figure 12The lower limb positioning support 8 in the embodiment specifically comprises a support assembly plate 81, an assembly plate connecting sleeve 82, a rotary positioning disc 83, a reciprocating connecting rod 84, a lower limb stop column 85 and a spring positioning pin 86. The support assembly plate 81 is the overall assembly body of the lower limb positioning support. The support assembly plate 81 is hingedly connected to the end of the second swing support 72 of the third cantilever 7 through the assembly plate connecting sleeve 82. The second swing support 77 is arranged between the support assembly plate 81 and the second swing support 72. The support assembly plate 81 is horizontally arranged and is provided with two groups of parallel downward lower limb stop columns 85. After the patient is punctured and his feet are put through the two groups of lower limb stop columns 85, the patient's lower limbs are positioned by adjusting the third cantilever and the support assembly plate to make the lower limbs curl up. The lower limb stop columns 85 are wrapped with soft cushioning materials such as sponge sleeves.

[0070] The lower limb positioning support 8 in the embodiment can adjust the distance between the lower limb stop columns 85 according to the thickness of the lower limbs of patients with different body sizes.
