Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a chest cavity auxiliary support device for cardiac surgery. Background Art

[0002] When performing heart surgery, the chest cavity needs to be opened for operation. To facilitate the operation, auxiliary tools are needed to open the chest incision and expand the incision position for surgery.

[0003] In the prior art, a Chinese patent with the announcement number CN110731803B discloses a cardiac surgery assistant, which expands the patient's chest cavity by moving the expansion plate outward to facilitate the operation of medical staff. However, when cardiac surgery is performed, the patient's chest cavity needs to be opened for surgical operation. In the past, the chest cavity is in a state of continuous contraction due to the physiological breathing of the patient. When the above assistant is used, the chest cavity is easily separated from the expansion plate due to the contraction of the chest cavity, resulting in poor expansion stability.

[0004] Therefore, it is necessary to propose a cardiac surgery chest auxiliary support device to solve the above problems. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a cardiac surgery chest auxiliary support device to solve the problem in the prior art that due to the patient's need for physiological breathing, the chest cavity is in a state of continuous contraction, which can easily cause the chest cavity to detach from the expansion plate, resulting in poor expansion stability.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The invention provides a thoracic auxiliary support device for cardiac surgery, comprising a bed plate, the bed plate being provided with a support frame which can slide along the length direction of the bed plate, the support frame being slidably provided with a mounting frame which can slide along the width direction of the bed plate, the mounting frame being rotatably provided with a bidirectional screw rod, the opposite threads of the bidirectional screw rod being threadedly connected with a sliding block, the sliding block being limitedly slidably connected with the mounting frame, and the bidirectional screw rod being rotated to enable two sliding blocks to synchronously slide in opposite directions, the sliding block being slidably provided with a support which can slide limitedly along the axis direction of the bed plate, the support being horizontally arranged side by side with a first sliding hole and a second sliding hole, a spreading rod which can slide limitedly along the axis direction of the bed plate being slidably provided in the first sliding hole, a supporting rod being movably provided in the second sliding hole, the two spreading rods being located between the two supporting rods, the supporting frame being threadably connected with two bolts which can extend into the first sliding hole and the second sliding hole respectively, and the spreading rod or the supporting rod can be locked or unlocked by rotating the two bolts to respectively press against or disengage from the spreading rod or the supporting rod.

[0008] Furthermore, a support pad is installed on the ball joint at the bottom end of the support rod.

[0009] Furthermore, the second slide is formed into a T-shape, the horizontal section of the T-shape extends along the width direction of the bed board, the vertical section of the T-shape extends along the length direction of the bed board, the support rod is limitedly slidably installed in the horizontal section of the T-shape, the bolt corresponding to the second sliding hole extends from the vertical section of the T-shape to the second sliding hole, and the axial direction of the bolt is perpendicular to the horizontal section of the T-shape.

[0010] Furthermore, a toothed column is rotatably installed in the support frame, the axial direction of the toothed column is consistent with the width direction of the bed board, and a gear meshing with the toothed column is rotatably installed in the middle of the mounting frame, and the gear is coaxially fixedly connected with the bidirectional screw.

[0011] Furthermore, a screw rod is rotatably installed in the support frame, and the mounting frame is threadedly connected to the screw rod. Rotating the screw rod can move the mounting frame along the width direction of the bed board.

[0012] Furthermore, baffles are fixedly mounted on the top ends of the support rod and the spread rod, and the baffles are used to limit the support rod and the spread rod from sliding downward and leaving the support.

DETAILED DESCRIPTION

[0028] like Figures 1 to 3As shown, the present invention provides a chest auxiliary support device for cardiac surgery, comprising: a bed board 1, and a support frame 2 slidably mounted on the bed board 1 along the length direction of the bed board 1, a mounting frame 3 slidably mounted on the support frame 2, a bidirectional screw 4 rotatably mounted in the mounting frame 3, a slider 5 is threadedly connected to the opposite threads of the bidirectional screw 4, the slider 5 is limitedly slidably connected to the mounting frame 3, rotating the bidirectional screw 4 can make the two sliders 5 slide synchronously in opposite directions, and a support 6 that can slide in a limited position along the axial direction of the bed board 1 is slidably mounted on the slider 5. The support 6 is provided with a first sliding hole 601 and a second sliding hole 602 side by side in the horizontal direction. A spreading rod 7 capable of limited sliding along the axial direction of the bed board 1 is slidably installed in the first sliding hole 601. A support rod 8 is movably installed in the second sliding hole 602. The two spreading rods 7 are located between the two support rods 8. Two bolts 9 capable of extending into the first sliding hole 601 and the second sliding hole 602 respectively are threadedly connected to the support 6. The spreading rod 7 or the support rod 8 can be locked or unlocked by rotating the two bolts 9 to respectively press against or disengage from the spreading rod 7 or the support rod 8.

[0029] In this solution, the axis of the bed board 1 is the Z axis, the length direction of the bed board 1 is the X axis, and the width direction of the bed board 1 is the Y axis. When performing thoracic surgery on a patient, the patient lies on the bed board 1, and then slides the support frame 2 along the X axis direction to drive the mounting frame 3 to move to a position corresponding to the X axis direction of the surgical position, and then slides the mounting frame 3 to move the mounting frame 3 to a position corresponding to the Y axis direction of the surgical position, so that the expansion rod 7 corresponds to the expansion position on the Z axis, and then slides the expansion rod 7 along the Z axis to connect the bottom end of the expansion rod 7 to the expansion position, and then rotates the corresponding bolt 9 to make the bolt 9 and the expansion position. The rods 7 are pressed against each other to fix the expansion rod 7, and then the bidirectional screw 4 is rotated to drive the two expansion rods 7 to slide in opposite directions to expand the chest cavity; wherein, after the chest cavity is expanded, the support rod 8 is slid along the Z-axis direction so that the bottom end of the support rod 8 falls on the outside of the expanded chest cavity of the patient, and then the corresponding bolt 9 is rotated so that the bolt 9 and the support rod 8 are pressed against each other to fix the support rod 8. When the patient's chest cavity continuously rises and falls due to breathing, the support rod 8 can be driven to continuously rise and fall, thereby driving the support 6 to slide back and forth along the slider 5, so that the expansion rod 7 follows the continuous rise and fall of the chest cavity, so that the relative position of the expansion rod 7 and the chest cavity is fixed.

[0030] In this solution, a support rod 8 is provided so that when the patient's chest rises and falls due to breathing, the expansion rod 7 can be driven to move synchronously, so that the relative position of the expansion rod 7 and the chest is fixed, and the expansion rod 7 is prevented from being separated from the chest due to the rising and falling movement of the chest, thereby ensuring the stability of the chest expansion; and the expansion rod 7 is prevented from pressing the inside of the patient's chest due to the rising and falling movement of the chest, thereby increasing the safety hazard; and the support rod 8 is provided on one side of the expansion rod 7 to ensure the consistency of the chest rising and falling range; and the mounting frame 3 is slidably provided on the support frame 2, so as to be able to adjust the position of the expansion rod 7 along the width direction of the bed board 1.

[0031] In one embodiment of the present invention, a support pad 801 is installed at the ball joint at the bottom end of the support rod 8 to improve the degree of coordination between the support rod 8 and the patient's body and increase the contact area.

[0032] In one embodiment of the present invention, the second sliding hole 602 is T-shaped, the horizontal section of the T-shape extends along the width direction of the bed board 1, and the vertical section of the T-shape extends along the length direction of the bed board 1. The support rod 8 is installed in the horizontal section of the T-shape for limited sliding. The bolt 9 corresponding to the second sliding hole 602 extends from the vertical section of the T-shape to the second sliding hole 602, and the axial direction of the bolt 9 is perpendicular to the horizontal section of the T-shape.

[0033] In this solution, the support rod 8 can be adjusted in position along the width direction of the bed board 1 to adjust the distance between the spreading rod 7 and the support rod 8 so that the support rod 8 can find a position suitable for contacting the patient.

[0034] In one embodiment of the present invention, a toothed column 201 is rotatably installed in the support frame 2, and the axial direction of the toothed column 201 is consistent with the width direction of the bed board 1. A gear 301 meshing with the toothed column 201 is rotatably installed in the middle part of the mounting frame 3, and the gear 301 is coaxially fixedly connected with the bidirectional screw 4.

[0035] In this solution, rotating the toothed column 201 can drive the gear 301 to rotate, thereby driving the bidirectional screw 4 to rotate; and when the mounting frame 3 slides on the support frame 2 along the width direction of the bed board 1, the gear 301 can slide along the axial direction of the toothed column 201, so that the gear 301 and the toothed column 201 always remain in a meshing state.

[0036] In this solution, the toothed column 201 is set as a driving part to avoid operation by medical staff and to avoid medical staff following the movement of the mounting frame 3 to operate the rotation of the bidirectional screw 4. The bidirectional screw 4 is set inside the mounting frame 3 to avoid the bidirectional screw 4 extending outside the mounting frame 3 to make it difficult to clean and disinfect.

[0037] In one embodiment of the present invention, a screw rod 202 is rotatably installed in the support frame 2 , and the mounting frame 3 is threadedly connected to the screw rod 202 . Rotating the screw rod 202 can move the mounting frame 3 along the width direction of the bed board 1 .

[0038] In this solution, by providing the screw rod 202, the stability of the mounting frame 3 moving to the preset position is ensured, and the medical staff is prevented from accidentally touching the mounting frame 3 and causing the mounting frame 3 to slide.

[0039] In one embodiment of the present invention, a baffle 10 is fixedly mounted on the top of each of the support rod 8 and the opening rod 7, and the size of the baffle 10 is larger than the size of the first sliding hole and the second sliding hole, so as to prevent the support rod 8 or the opening rod 7 from sliding downward and detaching from the support 6.

[0040] A method for implementing a chest auxiliary support device for cardiac surgery comprises the following steps:

[0041] S1: After the patient lies on the bed board 1, the support frame 2 is slid along the length direction of the bed board 1 so that the expansion rod 7 corresponds to the X-axis direction of the expansion position of the patient's chest cavity;

[0042] S2: Rotate the screw rod 202 to move the mounting frame 3 along the width direction of the bed board 1 so that the expansion rod 7 corresponds to the Y-axis direction of the expanded position of the patient's chest cavity;

[0043] S3: Turn the bolt 9 corresponding to the spreading rod 7 to disengage the bolt 9 from the spreading rod 7 to unlock the two spreading rods 7, and slide the spreading rod 7 along the axis of the bed board 1 so that the bottom end of the spreading rod 7 falls on the spreading position;

[0044] S4: Reversely rotate the bolt 9 corresponding to the spreading rod 7 so that the bolt 9 is pressed against the spreading rod 7 to lock the two spreading rods 7;

[0045] S5: Rotate the bolt 9 corresponding to the support rod 8 to disengage the bolt 9 from the support rod 8 to unlock the two support rods 8, move the support rod 8 to the outside of the patient's chest expansion position, and then reversely rotate the bolt 9 corresponding to the support rod 8 to tighten the bolt 9 against the support rod 8 to lock the two support rods 8;

[0046] S6: Medical staff will then perform thoracic surgery.

[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
