[0027] The utility model provides a kind of surgical lateral position fixing device, to solve the technical problem that the surgical lateral position fixing device in the related art is not stable, leading to the technical problem that operation accuracy is not high.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail in the following in conjunction with the drawings of the specification and specific implementation.

[0029] AsFigures 1 to 4 As shown in the drawings, one or more embodiments of the present application provide a lateral position fixing device for surgery, which, in the direction of the use state of the fixing device, comprises a bed body, a mattress 10 is laid on the bed body for a patient to lie on (of course, the mattress 10 can also be used with an existing hospital bed), a front side (the side facing the front when the patient lies on the mattress 10) edge of the mattress 10 is movably provided with a front side baffle 30, and an opposite rear side (the side facing the back when the patient lies on the mattress 10) edge of the mattress 10 is fixedly provided with a rear side baffle 40. The front side baffle 30 is movable relative to the rear side baffle 40 to move away from or close to the rear side baffle 40, so as to adjust the distance between the front side baffle 30 and the rear side baffle 40, thereby clamping the patient between the front side baffle 30 and the rear side baffle 40 to provide lateral support and ensure that the patient is stable in a lateral position, and since the distance adjustment between the rear side baffle 40 and the front side baffle 30 is non-mechanical adjustment, the adjustment accuracy is high. Therefore, when the patient lies on the mattress 10, the front side baffle 30 is slid to clamp the patient between the front side baffle 30 and the rear side baffle 40 and lock the rear side baffle 40, so as to define the patient in a lateral position, and the patient is not easy to move, thereby improving the accuracy of surgery.

[0030] As shown in the drawings, Figure 3 , 4 The mattress 10 is provided with a slide rail 80 along the width direction of the mattress 10, and the slide rail 80 is provided with threads extending along the length direction of the slide rail 80. The front side baffle 30 is arranged on the slide rail 80 and is slidable along the slide rail 80. The slide rail 80 is provided with a locking nut between the front side baffle 30 and the front side edge of the mattress 10. When the front side baffle 30 is moved to a target position, the nut is tightened on the slide rail 80 to abut against the front side baffle 30, thereby limiting the movement of the front side baffle 30 to the front side, so as to force the front side baffle 30 to laterally support the human body and make the patient stable in a lateral position. Of course, the front side baffle 30 can also be locked on the slide rail 80 by other ways, which is not limited herein.

[0031] It should be noted that the rear side baffle 40 is fixed by moving the front side baffle 30, which is in line with the operation habit and is more conducive to the cooperation of the patient. Of course, if the front side baffle 30 is fixed, the rear side baffle 40 can also be moved.

[0032] As shown in the drawings, Figure 3 , 4 In order to improve the stability of the movement of the rear side baffle 40 and the stability of the support of the rear side baffle 40 to the human body, the slide rail 80 can be provided with at least two slide rails, and the locking nut is arranged on each slide rail 80.

[0033] Further, in order to improve the comfort, the upper surface of the mattress 10 is a gas cushion layer, and the gas cushion layer comprises a plurality of air bags 20 arranged along the length direction of the mattress 10, the air bags 20 are in strip shape extending along the width direction of the mattress 10, the air bags 20 are formed with first air cavities, the first air cavities are formed with first inflation ports, the first inflation ports are provided with sealing plugs, and the first air cavities can be inflated by the inflation pump through the first inflation ports, so as to adjust the protruding degree of the air bags 20, and the gas cushion layer can adjust the inflation amount in different areas to match different parts of the human body. For example, the inflation amount of the air bags 20 at the waist position is increased, so that the air bags 20 at the waist position are more protruding, so that the waist is better supported and the comfort is improved. When the patient lies on the gas cushion layer, the soft contact can improve the comfort; at the same time, by adjusting the inflation amount of the air bags 20 at different positions, it is ensured that the gas cushion layer is in contact with different parts of the human body, so that good support is achieved, the patient is less likely to move, and the accuracy is further improved; in addition, the body shape of different patients can be matched, which is very practical.

[0034] It should be noted that the slide rail 80 is arranged between two adjacent air bags 20 to avoid the arrangement limitation of the air bags 20 on the slide rail 80.

[0035] Further, as shown in Figures 1 to 5 in order to improve the comfort, one side of the front baffle 30 and the rear baffle 40 in contact with the human body is an inflatable cushion to form soft contact with the human body, so as to improve the comfort, the inflatable cushion is formed with a second air cavity, the second air cavity is formed with a second inflation port, the second inflation port is provided with a second sealing plug, and the second air cavity can be inflated by the inflation pump through the second inflation port, so as to adjust the contact tightness of the front baffle 30 and the rear baffle 40 with the human body to provide more stable support.

[0036] In addition, the front baffle 30 is used to contact the perineal part of the human body, and one side of the front baffle 30 in contact with the human body is a first curved surface 31 matched with the concave-convex shape of the perineal part of the human body, and the rear baffle 40 is used to contact the buttocks of the human body, and one side of the rear baffle 40 in contact with the human body is a second curved surface 41 matched with the concave-convex shape of the buttocks of the human body. In this way, when the patient lies on the mattress 10, the front baffle 30 and the rear baffle 40 are in close contact with the human body, the limiting is very stable, which is beneficial to maintain the lateral position of the patient and improve the accuracy of the operation.

[0037] Specifically, as shown in Figure 5As shown, the first curved surface 31 is formed with a first arc-shaped protrusion 32 for pressing against the perineum, the second curved surface 41 is formed with an arc-shaped recessed portion 42 for accommodating the buttocks, and a second arc-shaped protrusion 43 for abutting against the waist, so that the front side baffle 30 and the rear side baffle 40 are in close contact with the human body, the limiting is very stable, which is beneficial to maintaining the lateral decubitus position of the patient and improving the accuracy of the operation.

[0038] For example, in actual use, when the patient is lying on the side on the mattress 10 with the buttocks abutting against the second curved surface 41 of the rear side baffle 40, the front side baffle 30 is gradually pushed, and when the distance between the front side baffle 30 and the skin of the patient is 1-2 cm, the inflatable pads on the front side baffle 30 and the rear side baffle 40 are inflated according to the body of the patient, so that the front side baffle 30 and the rear side baffle 40 are accurately attached to the body of the patient, ensuring the stability and accuracy of the lateral position.

[0039] As shown in the drawings, Figures 1 to 4 The lower side of the mattress 10 near the end of the bed is connected with an inflatable bag 50 through a connecting rope, so that the inflatable bag 50 can be folded onto the upper surface of the mattress 10. When the inflatable bag 50 is inflated, the patient lying on the mattress 10 can clamp the inflatable bag 50 between the two legs to avoid direct contact between the bones of the two legs, disperse the joint pressure, reduce the friction of soft tissues, improve the comfort of the legs, and is beneficial to maintaining the lateral decubitus position of the patient and improving the accuracy of the operation. In addition, in order to improve the skin-friendliness, the inflatable bag 50 can be made of silicone.

[0040] It should be noted that arranging the inflatable bag 50 under the mattress 10 can avoid interference with the operation when not in use, improving convenience.

[0041] Further, as shown in the drawings, Figures 1 to 4 The outer side of the head end of the mattress 10 is provided with a ring-shaped inflatable arm sleeve 70 for the arm to pass through, which is constructed with a ring-shaped channel, and the upper arm of the patient in the lateral decubitus position can be inserted into the channel of the inflatable arm sleeve 70 to provide comfortable support for the arm, thereby improving the use comfort, being beneficial to maintaining the lateral decubitus position of the patient, and further improving the accuracy of the operation.

[0042] Still further, as shown in the drawings, Figures 1 to 4 The upper surface of the head end of the mattress 10 is provided with an inflatable pillow 60 to provide support for the head, thereby improving the use comfort, being beneficial to maintaining the stable position, and further improving the accuracy of the operation.
