[0001] This invention relates to the field of auxiliary fixation equipment for puncture, specifically to an overall fixation device for upper body positioning and a puncture fixation bed. Background Technology

[0002] Bone marrow aspiration requires pre-operative anesthesia, which may cause some pain. Some patients are very sensitive to pain and often exhibit non-cooperation, resisting violently and for extended periods. This typically requires considerable manpower to stabilize the surgical site before the surgeon can collect the bone marrow. Numerous factors, including variations in the bone marrow aspiration site during the procedure, individual patient growth differences, and height variations leading to uncertainty in the aspiration location, frequently result in surgical failure, termination, or unsatisfactory outcomes.

[0003] Existing patient-fixing beds typically use adjustable fixation components to secure various parts of the patient's body. This is suitable for patients of all body types during puncture procedures. However, some puncture procedures require multiple puncture sites and a long positioning time. Prolonged restraint of the patient's limbs may cause discomfort, and removing the restraints may lead to puncture failure or misalignment.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figure 1 As shown, the present invention provides an overall upper body fixation device and a puncture fixation bed, wherein the overall upper body fixation device comprises an adjustable alignment structure 1, a movable limiting structure 2, a positioning and anti-deviation component 3, and a follow-up limiting component 4.

[0047] The adjustable alignment structure 1 is on which the patient's upper body shoulder and arm are placed. The adjustable alignment structure 1 can be translated and adjusted to correspond to the position of the patient's upper body shoulder and arm.

[0048] The movable limiting structure 2 is movably mounted on the adjustable alignment structure 1. The movable limiting structure 2 moves with the adjustable alignment structure 1. The movable connection between the movable limiting structure 2 and the adjustable alignment structure 1 is aligned with the horizontal position of the patient's upper arm at the center of movement in the shoulder. The movable limiting structure 2 corresponds to the patient's upper arm and limits and moves the arm. The components inside the movable limiting structure 2 that correspond to the bending point of the patient's upper arm bones are movably connected. The length of the components inside the movable limiting structure 2 that correspond to the length of the patient's upper arm can be freely adjusted to correspond to the length of the patient's upper arm.

[0049] The positioning and anti-deviation component 3 is fixedly installed on the movable limiting structure 2. The positioning and anti-deviation component 3 is used to fix the end of the lower arm near the bending point of the arm bone. The positioning and anti-deviation component 3 moves with the movable limiting structure 2 to drive the movement of the lower arm in the upper body position.

[0050] The follow-up limiting component 4 is set on the movable limiting structure 2. The follow-up limiting component 4 moves with the movable limiting structure 2 and limits the side of the upper body shoulder.

[0051] In this embodiment of the invention, the fixation device mainly fixes the bones rather than the flesh, which can greatly reduce the slight movement of the flesh caused by bone movement during puncture. It is equipped with a movable limiting structure 2, which fixes the upper body position with a movable plate, and can drive the movement of the upper arm and lower arm, thereby enabling the movement of the upper body. This allows movement of non-puncture parts during puncture, avoiding discomfort caused by prolonged fixation of the limbs, and improving the overall comfort and practicality of the fixation device.

[0052] In this invention, the adjustable alignment structure 1 is used to properly align the human shoulder. To accommodate different body types, the adjustable alignment structure 1 adopts the following preferred embodiments, such as... Figure 2 As shown, the adjustable alignment structure 1 includes a mounting bed 15, a first mounting groove 11 disposed on the mounting bed 15, a first drive threaded rod 13 disposed in the first mounting groove 11, a second drive threaded rod 12 connected to the first drive threaded rod, and a mounting shaft seat 16 disposed in the first mounting groove 11. The end of the second drive threaded rod 12 is rotatably disposed in the mounting shaft seat 16. A shoulder support plate 14 is threadedly connected to the first drive threaded rod 13, and the shoulder support plate 14 is slidably disposed in the first mounting groove 11.

[0053] In the above embodiment, the shoulder support plate 14 can slide in the first mounting groove 11. The patient's shoulder is placed on the shoulder support plate 14. In order to make the adjustable alignment structure 1 correspond to the position of the patient's upper body shoulder and arm, it is necessary to drive the shoulder support plate 14 to move. Driving the first drive threaded rod 13 and the second drive threaded rod 12 to rotate can both drive the shoulder support plate 14 to move.

[0054] In order to drive the first drive threaded rod 13 and the second drive threaded rod 12 to rotate, the present invention also makes the following design: the end of the first drive threaded rod 13 is connected to a connecting rod 17, the connecting rod 17 is disposed through the mounting bed plate 15, the end of the connecting rod 17 extends outside the mounting bed plate 15, and the end of the connecting rod 17 is connected to a first adjustment knob 18.

[0055] In addition, in order to adjust the space between the two shoulder support plates 14 by bringing them closer or further apart, the threads of the first drive thread rod 13 and the second drive thread rod 12 need to be opposite in direction.

[0056] The positioning process of the adjustable alignment structure 1 is as follows: rotating the first adjustment knob 18 drives the connecting rod 17 to rotate, thereby driving the first drive threaded rod 13 and the second drive threaded rod 12 to rotate. Under the rotation of the first drive threaded rod 13 and the second drive threaded rod 12, the shoulder support plate 14 gradually moves inward or outward, so that the movable connection between the movable limiting structure 2 and the adjustable alignment structure 1 is consistent with the horizontal position of the patient's upper arm in the shoulder's center of motion, and the movable limiting structure 2 corresponds to the arm of the patient in the upper body position.

[0057] This invention uses a movable limiting structure 2 to limit and move the arm. The movable limiting structure 2 of this invention mainly adopts the following preferred embodiments, such as... Figure 2 and Figure 3 As shown, the movable limiting structure 2 includes a movable groove 22 disposed at the end of the shoulder support plate 14, a connecting shaft 24 disposed in the movable groove 22, and a movable connecting plate 23 rotatably disposed at the end of the shoulder support plate 14; the movable connecting plate 23 is rotatably disposed in the movable groove 22 via the connecting shaft 24, and a second mounting groove 21 is provided on the mounting bed plate 15, and the movable connecting plate 23 is slidably disposed in the second mounting groove 21.

[0058] The above design can drive the upper arm to move, and the connecting shaft 24 can rotate freely, thereby driving the movable connecting plate 23 to rotate, thereby driving the upper arm placed on the movable connecting plate 23 to move.

[0059] Since the upper arm length varies from person to person, in order to ensure that the positioning and anti-displacement component 3, which is fixed to the end of the lower arm near the bending point of the arm bone, corresponds exactly to the bending point of the human arm, the movable limiting structure 2 is also designed as follows: a telescopic plate 26 is sleeved on the movable connecting plate 23, and several mounting threaded holes 27 are provided on the side of the movable connecting plate 23. Several upper mounting holes 28 are provided on the side of the telescopic plate 26. A first positioning bolt 29 is installed on the telescopic plate 26. The first positioning bolt 29 passes through the upper mounting hole 28 and is threaded into the mounting threaded hole 27.

[0060] Based on the length of the upper wall of the human body, the telescopic plate 26 is slid on the movable connecting plate 23 so that the structure fixing the bending point of the arm corresponds exactly to the bending point of the human arm and wrist. At this time, the mounting threaded hole 27 corresponding to the upper mounting hole 28 is installed in the corresponding mounting threaded hole 27 through the first positioning bolt 29 passing through the upper mounting hole 28, thereby achieving the positioning of the telescopic plate 26.

[0061] In order to adjust the position of the telescopic plate 26 on the movable connecting plate 23, the present invention is designed as follows: a connecting cavity 25 is provided in the movable connecting plate 23; a gear plate 214 is provided in the end of the telescopic plate 26; the end of the gear plate 214 extends into the connecting cavity 25; a connecting gear 215 is provided in the connecting cavity 25; the connecting gear 215 meshes with the gear plate 214; a second adjusting knob 217 is connected to the outside of the connecting gear 215 through a connecting bolt 216; the connecting bolt 216 is provided through the inner wall of the connecting cavity 25.

[0062] The adjustment process of the telescopic plate 26 is as follows: rotating the second adjustment knob 217 drives the connecting gear 215 to rotate through the connecting bolt 216, thereby driving the gear plate 214 to move in the connecting cavity 25, and the gear plate 214 drives the position adjustment of the telescopic plate 26.

[0063] In addition, in order to drive the movement of the lower arm after the arm is fixed, the present invention also has the following design: a limiting shaft 218 is provided at the end of the telescopic plate 26, and a rotating plate 210 is rotatably connected to the limiting shaft; a plurality of lower positioning holes 211 are provided at the end of the telescopic plate 26; a plurality of upper positioning holes 212 are provided on the rotating plate 210; and a plurality of positioning mounting bolts 213 are provided on the rotating plate 210, and the positioning mounting bolts 213 are installed in the lower positioning holes 211 through the upper positioning holes 212.

[0064] When a puncture is required in the lower arm, the positioning and installation pin 213 is installed in the lower positioning hole 211 through the upper positioning hole 212 to fix the rotating plate 210. When the lower arm is not a puncture site, the bending point of the arm can be fixed directly, and the movement of the lower arm can be driven by frequently rotating the rotating plate 210.

[0065] In order to fix the bending point of the arm, the present invention provides a positioning and anti-displacement component 3, such as... Figure 4 As shown, the positioning anti-offset component 3 includes a movable groove 36 disposed on the rotating plate 210, a placement groove 31 and a positioning groove 32 slidably disposed in the movable groove 36, and a first connecting threaded bolt 33 disposed on the positioning groove 32; the first connecting threaded bolt 33 passes through the positioning groove 32 and is threadedly connected to the placement groove 31; both the positioning groove 32 and the placement groove 31 are provided with a first engaging groove 34, and a sponge pad 35 is disposed in the first engaging groove 34.

[0066] Place the bending point of the arm between the placement slot 31 and the positioning slot 32, move the placement slot 31 and the positioning slot 32 inward, align the bent protruding part of the arm with the first mating groove 34, rotate the first connecting threaded bolt 33 to make it pass through the positioning slot and be threaded onto the placement slot 31, thereby fixing the position of the bending point of the arm.

[0067] This invention uses a follower-type limiting component 4 to limit the shoulder side. The follower-type limiting component of this invention adopts the following preferred embodiments, such as... Figure 5 As shown, the follow-up limiting component 4 includes a connecting frame 41 disposed on the movable connecting plate 23, a limiting groove 42 disposed in the connecting frame 41, and a limiting arc plate 43 disposed in the limiting groove 42; a buffer spring 44 is disposed on the bottom surface of the limiting arc plate 43 and is connected to the limiting groove 42 through the buffer spring 44; the limiting arc plate 43 fits with the shoulder side of the upper body; and a rubber pad 45 is disposed inside the limiting arc plate 43.

[0068] In the above embodiment, as the shoulder support plate 14 gradually moves inward, the rubber pad 45 gradually approaches the shoulder side and then compresses the buffer spring 44. Under the limiting action of the buffer spring 44 and the limiting arc plate 43, the shoulder side is restricted between the limiting arc plates 43.

[0069] The present invention also provides a puncture fixation bed on which the above-mentioned upper body positioning overall fixation device is installed, and further includes a hip fixation component 5, which fixes the side of the hip of the human body, such as... Figure 1 and Figure 6 As shown, the hip fixing component 5 includes a third mounting groove 51 disposed on the mounting bed board 15, a sliding seat 52 slidably disposed on the third mounting groove 51, and a telescopic positioning plate 53 disposed in the sliding seat 52; the sliding seat 52 is fixed in the third mounting groove 51 by a second positioning bolt 54, and a hydraulic cylinder 55 is connected to the telescopic positioning plate 53, the telescopic positioning plate 53 is connected to the output end of the hydraulic cylinder 55, and the inside of the telescopic positioning plate 53 fits with the outside of the human hip.

[0070] The sliding seat 52 is moved so that it is directly below the buttocks of the human body. At this time, the hydraulic cylinder 55 drives the telescopic positioning plate 53 to gradually move inward until it fixes the outside of the human hip.

[0071] In summary, the main implementation process of this invention is as follows:

[0072] Place the patient on the mounting bed board 15, with the shoulder correspondingly placed on the shoulder support plate 14. Rotate the first adjustment knob 18 to drive the connecting rod 17 to rotate, thereby driving the first drive threaded rod 13 and the second drive threaded rod 12 to rotate. The shoulder support plate 14 gradually moves inward or outward, so that the movable connection of the movable limiting structure 2 and the adjustable alignment structure 1 is consistent with the horizontal position of the patient's upper arm in the shoulder's center of motion, and the movable limiting structure 2 is aligned with the patient's upper arm in the upper body position.

[0073] The sliding seat 52 is moved so that it is directly below the buttocks of the human body. At this time, the hydraulic cylinder 55 drives the telescopic positioning plate 53 to gradually move inward to fix the hip of the human body.

[0074] The arm is passed between the placement slot 31 and the positioning slot 32. According to the length of the upper arm, the second adjustment knob 217 is rotated to adjust the position of the telescopic plate 26 so that the placement slot 31 and the positioning slot 32 correspond exactly to the bending point of the arm and wrist. The telescopic plate 26 is positioned by the first positioning bolt 29. The placement slot 31 and the positioning slot 32 are moved inward so that the bent and protruding part of the arm is aligned with the first fitting groove 34. The first connecting threaded bolt 33 is rotated to pass through the positioning slot 32 and be threaded onto the placement slot 31 to fix the position of the bending point of the arm.

[0075] The upper arm can be rotated via the movable connecting plate 23, and the lower arm can be rotated via the rotating plate 210.

[0076] In this invention, the movable connecting plate 23 is completely free to rotate. In practical applications, a threaded bolt that can be fixedly connected can also be provided at the movable connection between the movable connecting plate 23 and the shoulder support plate 14 to fix the upper arm when performing piercing work.

[0077] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
