Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an upper limb fixing device for a patient in a side-prone position. Background Art

[0002] In the operating room, the side-prone position is a specific position arrangement used for the patient's position during surgical operations or treatment. This position requires the patient to lie on the operating bed or table with the head slightly forward, so that the surgeon can better approach and handle specific parts or organs, ensuring the accuracy and safety of the surgical operation.

[0003] The Chinese patent with announcement number CN219878580U discloses a limb fixation device for nursing patients in the side-prone position in the operating room. The device is used to place the arm through an arm placement groove and an arm placement frame. The restraining rope is passed around the patient's waist and fixed by a fixing card, thereby fixing the patient's waist and limiting the position; giving the patient a more comfortable surgical experience and making the patient more stable and secure.

[0004] However, in the above-mentioned patent, the positions of the arm placement slot and the arm placement frame are relatively fixed, so the placement of the patient's arms is also relatively fixed. The position of the arms cannot be adjusted according to actual surgical needs, which may make it difficult for doctors to operate on specific parts, affecting the smooth progress of the operation and the efficiency of the operation, and the applicability is poor. Utility Model Content

[0005] The utility model aims to provide an upper limb fixation device for patients in a side-prone position, which can flexibly adjust the positions of both arms, is convenient for doctors to operate on specific parts and has good applicability.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] A device for fixing the upper limbs of a patient in a side-prone position comprises a bed board, a circular groove is provided on the upper surface of the bed board, a circular plate is rotatably installed inside the circular groove, and an arm placement groove is provided on the surface of the circular plate. A vertical plate is provided on the upper surface of the bed board, a U-shaped frame is provided on the top of the vertical plate, an arm placement support plate is rotatably installed between the inner walls of both sides of the U-shaped frame through a rotating shaft, and an angle adjustment mechanism capable of driving the arm placement support plate to rotate is provided on the outer side of the U-shaped frame. A plurality of slots are provided on the upper surface of the bed board in a coaxial array around the circular plate, and an insert block is installed at the bottom of the vertical plate, and the insert block is adapted to the slot.

[0008] It can be seen that the angle of the arm placement slot can be adjusted by rotating the circular plate, and then the patient's lower arm can be adjusted to a suitable angle, and the patient's upper arm can be placed at different angles by inserting the plug into the slot at different angles, and through the setting of the angle adjustment mechanism, the inclination angle of the arm placement support plate can be adjusted, and the inclination angle of the patient's upper arm can also be adjusted, so that the patient's arms can be placed in different positions according to different surgical conditions, which is convenient for doctors to operate on specific parts, and has good applicability.

[0009] Furthermore, the angle adjustment mechanism includes two side blocks installed on the outside of the U-shaped frame, a worm is rotatably connected between the two side blocks, one end of a rotating shaft passes through the outside of the U-shaped frame and is installed with a worm wheel, and the worm wheel is meshingly connected with the worm.

[0010] When the inclination angle of the patient's upper arm needs to be adjusted, the worm can be turned. Since the worm and the worm wheel are meshed with each other, the worm wheel can be driven to rotate, and through the connection of the rotating shaft, the arm placement tray can be driven to rotate to achieve the purpose of angle adjustment. In addition, the worm and the worm wheel have good self-locking properties, which can ensure the stability of the patient's upper arm when it is placed.

[0011] Furthermore, an adjustment rod is inserted into the interior of the vertical plate, and the U-shaped frame is installed on the top of the adjustment rod. The outer surface of the adjustment rod is provided with multiple adjustment holes along its height direction. The outer surface of the vertical plate is installed with fastening bolts, and the fastening bolts are adapted to the adjustment holes.

[0012] The height of the arm support plate can be adjusted by setting the adjusting rod, adjusting hole and fastening bolt, so as to meet the use of patients of different body shapes. When adjusting, first unscrew the fastening bolt from the current adjusting hole, then slide the adjusting rod up and down to adjust the height of the arm support plate, and finally screw the fastening bolt back into the adjusting hole corresponding to its current position.

[0013] Furthermore, the upper surface of the circular plate is flush with the upper surface of the bed board.

[0014] Since the surface of the round board is flush with the surface of the bed board, the patient will not feel obvious discomfort when lying on the bed board and the round board.

[0015] Furthermore, a screw is installed on the outer surface of the bed board, and the end of the screw is in contact with the circular plate.

[0016] The screw is turned so that its end abuts against the side surface of the circular plate, so that the circular plate can be fixed. Moreover, since the patient's own weight plays a partial fixing role when lying on the bed and the circular plate, the two forces cooperate with each other to ensure the stability of the circular plate and avoid rotation during the operation, which may affect the surgical operation and even cause medical accidents.

[0017] Furthermore, rubber pads are provided inside the arm placement slot and on the surface of the arm placement support plate, and straps are provided on the outside of the arm placement slot and the arm placement support plate.

[0018] The rubber pad can improve the comfort of the arm, and the strap can be used to tightly fix the patient's arm, thereby preventing the arm from sliding sideways during surgery and causing medical accidents. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of slots 400 are provided in a coaxial array around the circular plate 102 on the upper surface of the bed board 100, an insert block 401 is installed at the bottom of the vertical plate 104, and the insert block 401 is adapted to the slot 400.

[0026] During use, according to the surgical requirements, the doctor first rotates the circular plate 102 to make the arm placement slot 103 at a suitable angle. Then the patient lies in a prone position on the bed board 100 and the circular plate 102, with the patient's lower arm placed in the arm placement slot 103. Then the insert block 401 is pulled out from the current slot 400 and inserted into the slot 400 at a suitable angle according to the surgical requirements. Then the patient's upper arm is placed on the arm placement support plate 106, and the arm placement support plate 106 can be driven to rotate by the angle adjustment mechanism 200 to adjust the inclination angle of the patient's upper arm. Therefore, the patient's arms can be placed in different positions according to different surgical conditions, which is convenient for the doctor to operate on specific parts and has good applicability.

[0027] Specifically, the angle adjustment mechanism 200 includes two side blocks 202 installed on the outside of the U-shaped frame 105, and a worm 203 is rotatably connected between the two side blocks 202. The end of one of the rotating shafts passes through the outside of the U-shaped frame 105 and is installed with a worm wheel 201, and the worm wheel 201 is meshed with the worm 203. When the inclination angle of the patient's upper arm needs to be adjusted, the worm 203 can be screwed. Since the worm 203 and the worm wheel 201 are meshed with each other, the worm wheel 201 can be driven to rotate, and through the connection of the rotating shaft, the arm placement tray 106 is driven to rotate to achieve the purpose of angle adjustment. In addition, the worm 203 and the worm wheel 201 have good self-locking properties, which can ensure the stability of the patient's upper arm when it is placed.

[0028] Specifically, an adjusting rod 300 is inserted into the interior of the vertical plate 104, and the U-shaped frame 105 is installed on the top of the adjusting rod 300.

[0029] Specifically, the upper surface of the circular plate 102 is flush with the upper surface of the bed board 100 . Since the surface of the circular plate 102 is flush with the surface of the bed board 100 , when the patient lies on the bed board 100 and the circular plate 102 , there will be no obvious discomfort.

[0030] Specifically, a screw 500 is installed on the outer surface of the bed board 100, and the end of the screw 500 is in contact with the circular plate 102. By twisting the screw 500 to make its end abut against the side surface of the circular plate 102, the circular plate 102 can be fixed. Moreover, when the patient lies on the bed board 100 and the circular plate 102, his own weight has played a partial fixing role. The two forces cooperate with each other to ensure the stability of the circular plate 102, avoid rotation during the operation, affect the surgical operation and even cause medical accidents.

[0031] Specifically, rubber pads are provided inside the arm placement groove 103 and on the surface of the arm placement support plate 106, and straps 107 are provided on the outside of the arm placement groove 103 and the arm placement support plate 106. The setting of the rubber pads can improve the comfort of the arm, and the setting of the straps 107 can tighten and fix the patient's arm, thereby preventing the arm from slipping sideways during the operation and causing medical accidents.
