Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically provides a body position adjustment device suitable for an operating room. Background Art

[0002] During surgery, the patient will be placed in a suitable position according to different surgeries. The positions are generally divided into supine position, lateral position, prone position, lithotomy position and semi-sitting position. Among them, the lithotomy position is a commonly used surgical position for exposing the perineum, and is usually applied to surgeries and diagnostic and treatment operations in obstetrics and gynecology, urology, anorectal department, etc. The purpose of this position is to facilitate the doctor to perform the surgery or examination, and at the same time maximize the exposure of the patient's perineum.

DETAILED DESCRIPTION OF THE INVENTION

[0025] 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 only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-7, an embodiment provided by the present invention: A body position adjustment device suitable for an operating room, including an operating table 1, four universal wheels 2 are provided at the bottom of the operating table 1, a mattress 3 is provided on the operating table 1, a receiving groove 17 is provided on the operating table 1, a guide rail 9 is provided on the operating table 1, two sliders 10 are limitedly slidably arranged inside the guide rail 9, rotating mechanisms 5 are provided at the tops of the two sliders 10, brackets 14 are fixedly provided at the tops of the two rotating mechanisms 5, elastic straps 15 are fixedly provided at the tops of the two brackets 14, support plates 16 are fixedly provided at one ends of the two brackets 14, a judging mechanism 4 for judging the maximum degree of ligament stretching of the patient is provided at one end of the two brackets 14 away from the support plate 16, a protection mechanism 6 for protecting the patient's ligaments is slidably arranged inside the two sliders 10, a baffle 18 is fixedly provided at the top of the operating table 1, a transverse groove 181 is provided on the baffle 18, a U-shaped plate 11 is fixedly provided at the bottom of the operating table 1, a return spring 12 is provided at the top of the U-shaped plate 11, a return disk 13 is fixedly provided at the top of the return spring 12, one ends of two return ropes are provided at the top of the return disk 13, and the other ends of the two return ropes are fixedly connected to one side wall of the two sliders 10 respectively. A traction mechanism 7 is provided on the side wall of the operating table 1, and the traction mechanism 7 is fixedly connected to the other side wall of the two sliders 10 respectively. Two guide plates 8 are fixedly provided at the top of the operating table 1. First, place the patient's calves on the brackets 14, then fix the calves through the elastic straps 15. Then, the doctor drives the two sliders 10 and the brackets 14 to move synchronously towards both sides by shaking the traction mechanism 7. When the angle between the legs reaches the limit where the patient's ligaments are stretched relatively large, at this time, the inner side of the calf joint presses the judging mechanism 4, so that the judging mechanism 4 makes the rotating mechanisms 5 dock. At this time, while the traction mechanism 7 drives the sliders 10 to slide towards both sides, the rotating mechanism 5 drives the brackets 14 to rotate outwards, and the rotation of the brackets 14 drives the legs to adjust the angle. When the medical staff feels an instantaneous increase in resistance when shaking the traction mechanism 7, this is the characteristic of the human body protection mechanism. At this time, it is the maximum angle at which the patient's legs are opened. At this time, the medical staff locks the traction mechanism 7 and synchronously drives the protection mechanism 6 to work, driving the brackets 14 to slide inwards, and synchronously driving the brackets 14 to recover a certain angle inwards, so that in the case where the patient opens the maximum angle, it is possible to avoid leg strains caused by excessive stretching of the patient, and cooperate with the human body protection mechanism to adapt to all people. Through the protection mechanism 6, it is realized to ensure that the patient is in the best leg opening angle and can maintain the lithotomy position for a long time. When the operation is completed, unlock through the locking mechanism. At this time, the return spring 12 pulls the return disk 13 to move downwards, and the downward movement of the return disk 13 drives the return ropes to pull the sliders 10 to slide inwards. Then, by untying the elastic straps 15, the patient's legs can be put down.

[0027] Specifically, the traction mechanism 7 includes two first rotating shafts 71, two guide wheels 72, two first traction ropes 73, two winding wheels 74, a fixed plate 75, a rotating plate 76, a locking assembly 77, a plurality of locking holes 78 and a transmission shaft 79. The two first rotating shafts 71 are both rotatably arranged on the top of the operating bed 1, the two guide wheels 72 are respectively fixedly arranged on the corresponding first rotating shafts 71, one ends of the two first traction ropes 73 are respectively fixedly arranged on the side walls of the two sliders 10, the transmission shaft 79 is rotatably arranged inside the operating bed 1, the two winding wheels 74 are limitedly slidably arranged on the transmission shaft 79, the fixed plate 75 is fixedly arranged on the side wall of the operating bed 1, the rotating plate 76 is fixedly arranged on the end of the transmission shaft 79, the plurality of locking holes 78 are arranged in a circular array on the fixed plate 75, and the locking assembly 77 is fixedly arranged on the fixed plate 75. By holding the locking assembly 77 and shaking it, the turntable 76, the transmission shaft 79 and the winding wheel 74 are driven to rotate synchronously. The winding wheel 74 rotates to reel in the first traction rope 73, so that the traction slider 10 slides toward both sides with the inside of the slide rail. By pressing the turntable 76, the locking assembly 77 and the transmission shaft 79 are driven to move synchronously. The locking assembly 77 is inserted into the corresponding locking hole 78 to lock the position of the turntable 76. Manual traction is achieved to adjust the patient's leg opening angle, avoiding the inability to feel the resistance when adjusting the opening angle through electric adjustment, which causes the patient to open the leg too much and causes discomfort to the patient.

[0028] Specifically, the locking assembly 77 includes two U-shaped rods 771, two locking springs 772 and a tapered rod 773. The tapered rod 773 is fixedly arranged on the rotating disk 76. The two U-shaped rods 771 are slidably arranged inside the tapered rods 773. The two locking springs 772 are fixedly arranged between the two U-shaped rods 771. The two U-shaped rods 771 are provided with an inclined surface on one side wall close to the fixed disk 75. The rotating disk 76 is driven to move by pressing the rotating disk 76, and the rotating disk 76 moves to drive the tapered rod 773 to be inserted into the locking hole 78. When the tapered rod 773 is inserted into the locking hole 78, the U-shaped rod 771 is resisted and squeezed by the locking spring 772. When the tapered rod 773 is gradually inserted, the U-shaped rod 771 is reset by the force of the locking spring 772 and locked with the locking hole 78. When unlocking, it is only necessary to press the U-shaped rod 771 and then pull out the tapered rod 773.

[0029] Specifically, the rotating mechanism 5 includes a rotating gear 51, a rotating rack 52, a hollow rod 53 and a fixed rod 54. The hollow rod 53 is fixedly arranged at the bottom of the bracket 14. The rotating rack 52 is fixedly arranged on the baffle 18. The rotating gear 51 is rotatably arranged on the top of the slider 10. The fixed rod 54 is fixedly arranged inside the rotating gear 51. The movement of the slider 10 drives the movement of the rotating gear 51. While the rotating gear 51 is moving, it rotates itself under the cooperation of the rotating rack 52. The rotation of the rotating gear 51 drives the rotation of the fixed rod 54 and the hollow rod 53, and the rotation of the hollow rod 53 drives the rotation of the bracket 14. When the opening angle of the patient's thigh is relatively large, it is possible to avoid the opening angle of the patient's thigh being too large. At this time, by cooperating with the rotation of the lower leg angle, the surgical field of view of the perineum is maximally exposed, facilitating the medical staff to perform the operation.

[0030] Specifically, the judging mechanism 4 includes two elastic gaskets 41, two air bags 42, a connecting pipe 43, a straight pipe 44, a moving block 45 and a docking groove 46. The docking groove 46 is arranged inside the fixed rod 54. The two air bags 42 are arranged on the inner wall of one end of the bracket 14. One end of the two elastic gaskets 41 is fixedly arranged on the inner wall of the bracket 14. The moving block 45 is slidably arranged inside the hollow rod 53. One end of the connecting pipe 43 is communicated with the inner air bag 42. The straight pipe 44 is arranged inside the hollow rod 53. One end of the straight pipe 44 is fixedly connected to the other end of the connecting pipe 43. As the patient's legs gradually open along with the bracket 14, the inner sides of the patient's legs come into contact with the spring gaskets as they gradually open. The elastic gaskets 41 deform and squeeze the air bags 42. The gas in the air bags 42 is extruded from the connecting pipe 43 and the straight pipe 44, thereby pushing the moving block 45 downward. The moving block 45 moves downward and inserts into the docking groove 46. It realizes the characteristic that when the legs open close to the limit according to the body's protection mechanism, the resistance will increase instantaneously, so as to judge the different maximum opening angles of different patients, which is applicable to the vast majority of people, has strong applicability, and the setting of the air bags 42 can also support the popliteal fossa of the patient, avoiding the nerves in the popliteal fossa being compressed and causing the patient to be injured, facilitating the exposure of the surgical field of view and surgical operation.

[0031] Specifically, chutes are arranged on the tops of the two sliders 10, and through grooves are arranged inside the two sliders 10.

[0032] Specifically, the protection mechanism 6 includes two triangular plates 61, two connecting rods 62, a telescopic plate 63, two T-shaped grooves 64, two protection springs 65, a first rack 66, a protection gear 67, a second rack 68, two T-shaped blocks 69 and two wedge-shaped blocks 610. The two wedge-shaped blocks 610 are slidably limited in the two through grooves. The telescopic plate 63 is slidably limited in the direction towards the receiving groove 17 on the top of the operating table 1. The telescopic plate 63 is arranged with a structure that can be telescoped at both ends and fixed in the middle. The two connecting rods 62 are respectively fixedly arranged at both ends of the telescopic plate 63. The second rack 68 is slidably arranged inside the receiving groove 17. The first rack 66 is fixedly arranged in the middle of the telescopic plate 63. The two triangular plates 61 are fixedly arranged at one end of the two connecting rods 62 away from the protection gear 67. The two T-shaped blocks 69 are respectively fixedly arranged on the side walls of the wedge-shaped blocks 610. The second rack 68 is rotationally matched with the transmission shaft 79. The two T-shaped grooves 64 are arranged on the side walls of the triangular plates 61. The two protection springs 65 are fixedly arranged inside the corresponding sliders 10. The two T-shaped blocks 69 are slidably matched with the corresponding T-shaped grooves 64. By pressing the turntable 76 to drive the transmission shaft 79 to move, the movement of the transmission shaft 79 drives the second rack 68 to move. The movement of the second rack 68 drives the protection gear 67 to rotate. The rotation of the protection gear 67 drives the first rack 66 to move. The movement of the first rack 66 drives the telescopic plate 63 to move. The movement of the telescopic plate 63 drives the connecting rods 62 and the triangular plates 61 to move synchronously. The movement of the triangular plates 61 abuts against the movement of the wedge-shaped blocks 610. And because the rotating gear 51 is rotationally matched with the wedge-shaped blocks 610, the movement of the wedge-shaped blocks 610 drives the rotating gear 51, the fixed rod 54, the hollow rod 53 and the bracket 14 to move synchronously. The movement of the bracket 14 drives the opening angle of the thigh to shrink by a certain distance. While shrinking, it cooperates with the rotating gear 51 and the rotating rack 52 to drive the bracket 14 to rotate inwards by a certain angle; it realizes that for different patients, the maximum opening angle can be maintained without hurting the leg ligaments of the patients, which is not only convenient for the surgical operation of medical staff, but also can ensure the safety of the patients. At the same time, the patients can maintain this posture for a long time, meet the surgical requirements, reduce the number of relaxations during the operation, and improve the surgical efficiency.

[0033] Specifically, the two wedge-shaped blocks 610 are slidably limited in the two through grooves.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
