[0025] Example:
[0026] See also Figure 1-6The utility model provides a technical solution: a minimally invasive surgery patient position adjustment auxiliary device, including a fixing clamp 4, the fixing clamp 4 adopts a clamp in the prior art, and is used to be fixed on the edge of the bed for minimally invasive surgery patients, thereby fixing and supporting the device. A support column 3 is installed on the upper end of the fixing clamp 4, and the support column 3 is welded on the upper side of the fixing clamp 4; an adjustment bracket 2 is installed on the other end of the support column 3, and the adjustment bracket 2 is fixedly connected to the adjustment bracket 2 by bolts, so as to facilitate the disassembly and assembly between the adjustment bracket 2 and the support column 3.
[0027] The adjusting bracket 2 includes a bottom plate 28, which is fixedly connected to the supporting column 3, and a supporting plate 27 is welded on the upper side of the bottom plate 28; an adjusting plate No. 1 21 is installed on the upper side of the supporting plate 27, and the adjusting plate No. 1 21 is fixedly connected to the supporting plate 27 by bolts. The adjusting plate No. 1 21 is a fixed plane plate and does not participate in the angle rotation adjustment. The left and right sides of the adjusting plate No. 1 21 are hinged with the adjusting plate No. 22, and the other ends of the adjusting plates No. 2 22 on both sides are hinged with the adjusting plate No. 3 23. When supporting one of the four limbs of the human body, the adjusting plates No. 2 22 and the adjusting plates No. 3 23 are rotated to make an angle between the adjusting plate No. 2 22 and the adjusting plate No. 1 21, and an angle between the adjusting plate No. 3 23 and the adjusting plate No. 2 22. According to the bending angle required for minimally invasive surgery, the angles of the adjusting plates No. 2 22 and the adjusting plates No. 3 23 are adjusted, and they are fixed after the adjustment is completed. Angle brackets 29 are installed on the left and right sides above the bottom plate 28. The upper end of the angle brackets 29 is hinged with a transmission link 25. The other end of the transmission link 25 is hinged with a support link 24. The other end of the support link 24 is hinged with the third adjustment plate 23. A rotation-limiting mechanism 26 is arranged on the outer side of the transmission link 25 to limit the rotation of the support link 24 and the transmission link 25. After the transmission link 25 and the support link 24 are fixed by the rotation-limiting mechanism 26, the third adjustment plate 23 and the second adjustment plate 22 will also be fixed, so that they cannot rotate; the rotation-limiting mechanism 26 can adopt traditional friction fixing, but when the friction fixing bolts are loose, it will cause the third adjustment plate 23 and the second adjustment plate 22 to be unstable. Therefore, the rotation-limiting mechanism 26 can also adopt the following structure:
[0028] The rotation limiting mechanism 26 includes an anti-slip nut 261 and a push-pull screw 262; the anti-slip nut 261 is fixed on the outer side of the transmission connecting rod 25, and the push-pull screw 262 penetrates the transmission connecting rod 25 and is screwed to the anti-slip nut 261. The number of the rotation limiting mechanisms 26 for a single transmission connecting rod 25 is two, and the push-pull screws 262 on the two rotation limiting mechanisms 26 penetrate the support connecting rod 24 and the angle bracket 29 respectively when penetrating the transmission connecting rod 25. The outer side of the push-pull screw 262 is provided with a push column 264 and a push-pull sheet 263, and the outer side of the push-pull screw 262 is also provided with a gear column 265, and the gear column 265 is located between the push column 264 and the push-pull sheet 263; when the push-pull screw 262 is rotated, the push-pull screw 262 will drive the push column 264 and the push-pull sheet 263 to move, and drive the gear column 265 to move through the push column 264 and the push-pull sheet 263. The support link 24 and the transmission link 25 are both provided with a gear groove corresponding to the gear column 265 on the side close to the anti-slip nut 261, and the depth of the gear groove on the support link 24 and the angle bracket 29 is less than the height of the gear column 265, and the depth of the gear groove on the transmission link 25 is greater than the height of the gear column 265; when the gear column 265 is completely located on the inner side of the transmission link 25, the support link 24 and the transmission link 25 can rotate relative to each other; when the gear column 265 is located in the gear grooves on the angle bracket 29 and the transmission link 25, the angle bracket 29 will limit the rotation of the gear column 265, and the gear column 265 will limit the rotation of the transmission link 25; similarly, when the gear column 265 is located in the gear grooves of the support link 24 and the transmission link 25 at the same time, the support link 24 will be restricted by the transmission link 25 and the gear column 265, and thus cannot rotate.
[0029] A pad 1 is provided at the top of the adjustment bracket 2. The pad 1 can be made of polypropylene. The lower side of the pad 1 is respectively fitted with the No. 1 adjustment plate 21, the No. 2 adjustment plate 22 and the No. 3 adjustment plate 23. The material of the pad 1 is relatively soft and can bend with the change of the angle between the No. 1 adjustment plate 21 and the No. 2 adjustment plate 22 and the No. 2 adjustment plate 23, thereby preventing the No. 1 adjustment plate 21, the No. 2 adjustment plate 22 and the No. 3 adjustment plate 23 from squeezing the local joints of the patient when the edges and corners are bent. A protective groove is provided on the upper side of the pad 1.
[0030] The support column 3 includes a fixed base 37, and a guide column 32 is hinged on the upper end of the fixed base 37. The deflection angle of the adjustment bracket 2 can be adjusted by rotating the guide column 32, so that the adjustment bracket 2 can better fit the patient. A limiting mechanism 34 for limiting the rotation of the guide column 32 is provided on the outer side of the fixed base 37; the structure of the limiting mechanism 34 is the same as that of the rotation limiting mechanism 26, and also includes an anti-slip nut 261, a push-pull screw 262, a push-pull sheet 263, a propulsion column 264 and a gear column 265; then the guide column 32 and the fixed base 37 are both provided with a gear groove corresponding to the gear column 265 on the side close to the anti-slip nut 261, the depth of the gear groove on the guide column 32 is less than the height of the gear column 265, and the depth of the gear groove on the fixed base 37 is greater than the height of the gear column 265; when the gear column 265 is completely located on the inner side of the gear groove on the fixed base 37, the guide column 32 and the fixed base 37 can rotate relative to each other, and when the gear column 265 is stuck on the inner side of the gear groove on the guide column 32 and the fixed base 37 at the same time, the fixed base 37 will limit the rotation of the gear column 265, and the gear column 265 will limit the rotation of the guide column 32.
[0031] The guide post 32 is provided with a waist-shaped groove on one side, and a waist-shaped plate 33 is movably provided on the inner side of the waist-shaped groove; a telescopic post 31 is provided on the outer side of the guide post 32 for sliding sliding, and an anti-skid plate 35 is inlaid on the outer side of the telescopic post 31; the anti-skid plate 35 and the waist-shaped groove are provided with an anti-skid groove on the side close to each other, and an anti-skid post corresponding to the anti-skid groove is provided on the outer side of the waist-shaped plate 33. When the anti-skid post is fully pushed into the anti-skid groove on the anti-skid groove 35, the relative sliding between the telescopic post 31 and the guide post 32 is not hindered. At this time, the telescopic post 31 can be pulled to slide, and then the support post 3 can be lengthened to adjust the relative height of the adjustment bracket 2, so that the adjustment bracket 2 can support the human limbs adjusted to different heights; when the anti-skid post is pushed into the anti-skid groove on the waist-shaped groove, a part of the anti-skid post will be stuck in the anti-skid groove on the anti-skid plate 35. At this time, due to the restrictions of the anti-skid plate 35 and the anti-skid post, the guide post 32 and the telescopic post 31 cannot slide relative to each other. A locking stud 36 is provided on the outer side of the telescopic column 31; one end of the locking stud 36 passes through the telescopic column 31 and is screwed to the telescopic column 31, and the locking stud 36 passes through the waist plate 33 and is rotatably connected to the waist plate 33; when the locking stud 36 rotates, it will not drive the waist plate 33 to rotate, and at the same time, the locking stud 36 will push the waist plate 33 to move, thereby adjusting the position of the anti-slip column on the waist plate 33.
[0032] Working principle: When it is necessary to adjust the angles between the No. 1 adjustment plate 21, the No. 2 adjustment plate 22 and the No. 3 adjustment plate 23 on the adjustment bracket 2, firstly, the push-pull screw 262 on the rotation-limiting mechanism 26 is turned, and the push-pull screw 262 drives the gear column 265 to move, so that the gear column 265 completely enters a gear groove. At this time, the supporting connecting rod 24 and the transmission connecting rod 25, as well as the transmission connecting rod 25 and the angle bracket 29 can rotate relative to each other, and the No. 2 adjustment plate 22 and the No. 3 adjustment plate 23 are rotated to adjust the angle between the No. 2 adjustment plate 22 and the No. 1 adjustment plate 21. The angle between the second adjustment plate 22 and the third adjustment plate 23 is adjusted, and the support connecting rod 24 and the transmission connecting rod 25 will also rotate accordingly; after the angle adjustment is completed, the push-pull screw 262 on the rotation limiting mechanism 26 is turned again, and the push-pull screw 262 drives the gear column 265 to move, so that the gear column 265 is completely stuck in the two gear grooves. At this time, the gear column 265 is fixed with the gear groove, so that the support connecting rod 24 and the transmission connecting rod 25 are fixed, and the second adjustment plate 22 and the third adjustment plate 23 are also fixed.
