Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to an ERCP operation body position cushion. Background Art

[0002] ERCP (Endoscopic Retrograde Cholangiopancreatography) is a minimally invasive surgery combining endoscopy and X-ray, mainly used for diagnosing and treating diseases of the pancreaticobiliary system. An endoscope is inserted through the mouth, passes through the esophagus and stomach to reach the duodenum, finds the common opening of the pancreatic duct and bile duct, injects contrast agent and then performs X-ray imaging to help doctors observe the structure and function of the pancreaticobiliary duct.

[0003] During ERCP surgery, patients usually adopt the prone position or the left lateral position. In the prone position, the patient lies prone, with the head turned to one side, the arms placed naturally or on the side of the head, and the chest, hip and knee supported by a body position cushion. The prone position can make the duodenal papilla (the opening of the pancreaticobiliary duct) easier to expose, facilitating the insertion and operation of the endoscope; in the prone position, the imaging of the bile duct and pancreatic duct under X-ray is clearer, facilitating doctors' observation. However, in the prone position, the chest and abdomen of the patient will be compressed, resulting in lower comfort, and obese or patients with lung diseases may also have difficulty breathing due to chest compression. The left lateral position causes less compression on the chest, is suitable for obese or patients with poor respiratory function, and the anatomical position of the stomach and duodenum is more conducive to the passage of the endoscope; however, the exposure of the duodenal papilla may not be as sufficient as in the prone position, increasing the operation difficulty. In addition, the left lateral position may affect the imaging effect of the bile duct and pancreatic duct under X-ray. Flexibly selecting the operation body position according to the individual needs of the patient and the operation requirements plays an important role in the smooth progress of the operation.

[0004] Existing ERCP operation body position cushions, such as CN208426362U or CN109938959A, can only be applied to surgeries in a single body position. When different operation body positions are selected, different body position cushions are required, and the preoperative preparation process is relatively cumbersome. In addition, there will be a problem that the patient's breathing is blocked due to the compression in the prone position during ERCP surgery, and the operation body position of the patient needs to be adjusted temporarily. The above body position cushions cannot be adjusted and quickly switched according to the needs of the patient. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and illustrated herein can generally be arranged and designed in various different configurations.

[0042] Embodiment 1

[0043] As Figure 1 shown, this embodiment discloses an ERCP operation body position cushion, which includes a support member 1 and a main cushion body 2, and the main cushion body 2 is arranged on the top of the support member 1.

[0044] A head support cushion 3 and a trunk support member 4 are arranged on the main cushion body 2; the trunk support member 4 is composed of a plurality of support units 5 for supporting and limiting the trunk;

[0045] As Figure 2 and Figure 3 shown, the support unit 5 includes: a sliding support platform 51, a flap 52, a flipping support member 53, and a sliding adjustment member 54. The sliding support member 51 is arranged on the top of the main cushion body 2 and is slidably connected to the main cushion body 2; one side of the flap 52 is hinged to the sliding support platform 51, and a decompression pad 521 is arranged on the top of the flap 52. As Figure 3 shown, the decompression pad 521 is an elastic pad covering the upper surface of the flap, and the material can be high-density sponge, silicone, or gel material, which can provide support at the corresponding position and play a role in buffering and dispersing stress. The flipping support member 53 is used to adjust the flipping angle of the flap 52, and the sliding adjustment member 54 is used to adjust the position of the sliding support platform 51.

[0046] In this embodiment, the number of support units 5 is four, and two in a group respectively form a chest support part 41 and an anterior superior iliac spine support part 42. As Figure 1 shown, the chest support part 41 is arranged at the position corresponding to the upper chest, and two support units 5 are arranged on both sides of the main cushion body 2, which can support the upper chest and avoid pressing on the breasts at the same time. The anterior superior iliac spine support part 42 is arranged at the position corresponding to the anterior superior iliac spine, and two support units 5 are arranged on both sides of the main cushion body 2, which can support the anterior superior iliac spine. The chest support part 41 and the anterior superior iliac spine support part 42 select relatively stable bony structures at the trunk to provide support, avoid the soft tissues in the chest and abdomen, can provide effective and stable support, avoid pressing on the soft tissues in the chest and abdomen, and improve comfort.

[0047] As Figure 3 shown, the first groove 11 and the second groove 21 corresponding to each other are respectively arranged on the support member 1 and the main cushion body 2. The sliding support platform 51 is arranged above the second groove 21.

[0048] The bottom of the sliding support platform 51 is provided with a connecting rod 511 and a sliding head 512. The sliding head 512 slides along the second groove 21. The connecting rod 511 is arranged in the first groove 11 and is connected to the bottom of the sliding support platform 51 and the top of the sliding head 512 at both ends respectively.

[0049] The sliding adjustment member 54 includes a rotating handle 541 and a screw rod 542. A threaded hole 12 is provided on the side of the support member 1. The screw rod 542 passes through the threaded hole 12 and extends into the second groove 21, and is rotatably connected to one side of the sliding head 512 through a bearing; the rotating handle 541 is arranged at the end of the screw rod 542 and is located outside the support member 1. In this embodiment, the lateral position of the sliding support platform 51 can be quickly adjusted by rotating the rotating handle 541. The second groove 21 is used to limit the sliding head 512 so that the sliding head 512 can slide along the second groove 21. The first groove 11 provides a moving space for the connecting rod 511, so that while providing support for the sliding support platform 51, it can drive the sliding support platform 51 to slide laterally under the action of the screw rod 542.

[0050] One side of the sliding support platform 51 near the middle position of the main cushion 2 is provided with a protruding portion 513, and a hinge 514 is provided on the protruding portion 513. One end of the flap 52 is hinged to the sliding support platform 51 through the hinge 514.

[0051] As Figure 3 shown, the sliding support platform 51 is provided with a receiving gap 515 for placing the flipping support member 53 near the edge position of the main cushion 2.

[0052] As Figure 4 and Figure 5 shown, the flipping support member 53 in this embodiment is a support plate 531. One end of the support plate 531 is hinged to the bottom of the flap 52, and the other end is a free end.

[0053] The protruding portion 513 is provided with a receiving groove 516 for placing the support plate 531. When the flap 52 is in a horizontal state, the free end is located in the receiving groove 516. The sliding support platform 51 is provided with a plurality of card slots 517 for placing the free end. When it is necessary to flip the flap 52 to a specified angle, the flap 52 can be lifted to make the free end snap into the inside of the card slot 517 to complete the locking of the flap 52.

[0054] This embodiment has two usage methods. As Figure 1 shown, when the patient needs to be in the prone position, the flap 52 is in a horizontal state and the patient is in the prone state. The head, chest and anterior superior iliac spine positions are respectively supported by the head support cushion 3, the chest support portion 41 and the anterior superior iliac spine support portion 42; the above support positions can support the main stress positions of the patient in the prone position, thereby reducing the pressure on the patient's chest and abdomen and improving the comfort of the patient.

[0055] As Figure 4 shown, when the patient needs to lie on the left side, the flap 52 can be lifted to fix the flap 52 at a certain angle. Then, the positions of the sliding support platform 51 and the flap 52 are adjusted through the sliding adjustment member 54, so that the two flaps 52 can respectively clamp and support the patient's torso from the front and back sides of the patient, thereby playing a role in stabilizing the patient's torso.

[0056] As Figure 4 shown, a vertically arranged third groove 22 is provided on the main cushion body 2, and the bottom of the third groove 22 extends to the top of the support member 1. The support member 1 is provided with a plurality of insertion holes 13 in the corresponding third groove 22.

[0057] As Figure 6 shown, this embodiment is also provided with a leg fixing member 6. The bottom of the leg fixing member 6 is provided with an insertion end 61 that cooperates with the insertion hole 13, and the surface of the leg fixing member 6 is provided with an elastic pad 62. The number of the third grooves 22 is two, which are respectively arranged on both sides of the main cushion body 2.

[0058] The number of the leg fixing members 6 is two or more. The leg fixing members 6 are only used when lying on the left side. When the patient is in the left lateral position, the left leg is straightened and the right leg is bent. Two leg fixing members 6 can be inserted at the designated positions, so that the leg fixing members 6 can support and fix the patient's knees and feet from below.

[0059] As Figure 2 shown, the head support cushion 3 is annular and is provided with a neck opening 31 at the corresponding neck position; the main cushion body 2 and the support member 1 are provided with a second opening 7 at the corresponding bottom position of the head support cushion 3.

[0060] The top of the head support cushion 3 is provided with a second head cushion 32. The second head cushion 32 is detachably connected to the head support cushion 3. The bottom of the second head cushion 32 is provided with an insertion portion 33, and is inserted into the annular head support cushion 3 through the insertion portion 33 to maintain fixation.

[0061] Embodiment 2

[0062] This embodiment discloses an ERCP operation position cushion.

[0063] As Figure 7 shown, the end of the free end of the support plate 531 is provided with a bent portion 532, and the shape of the card slot 517 is adapted to the bent portion 532. In this embodiment, the setting of the bent portion 532 and the card slot 517 can effectively improve the clamping effect between the bent portion 532 and the card slot 517, and prevent the free end of the support plate 531 from popping out of the card slot 517 when the patient's body shakes.

[0064] The other structures of this embodiment are the same as those of Embodiment 1.

[0065] Embodiment 3

[0066] This embodiment discloses an ERCP operation position cushion.

[0067] In this embodiment, as Figure 8 shown, the flipping support member 53 is a folding airbag 533, and an inflation nozzle is provided on the folding airbag 533. Both ends of the folding airbag 533 are fixedly connected to the top of the sliding support platform 51 and the bottom of the flap 52 respectively. When the folding airbag 533 is inflated, the folding airbag 533 expands and lifts the flap 52, so as to clamp the body when the patient lies on the left side.

[0068] This embodiment adopts the folding airbag 533 as the flipping support assembly 53, which can further improve the comfort when clamping the body. After the operation is completed, the air can be released through the inflation nozzle to make the flap 52 return to the horizontal position.

[0069] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
