[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1-4 The utility model provides an embodiment: a joint fixation frame for orthopedic surgery, comprising a fixing plate 1, a triangular plate 2 is fixedly arranged at the bottom of the fixing plate 1, an adjusting mechanism is arranged inside the triangular plate 2, a fixing mechanism is arranged below the triangular plate 2, and the fixing mechanism is fixedly connected to the adjusting mechanism; the adjusting mechanism comprises a main gear 3 and a sub-gear 4, a sub-gear 4 is arranged on one side of the main gear 3, and meshing teeth are arranged on the outer sides of the sub-gear 4 and the main gear 3, and a moving rod 5 is fixedly arranged on the top of the main gear 3 and the sub-gear 4, and a moving groove 6 is penetrated on both sides of the triangular plate 2, and the moving rod 5 is movably connected with the moving groove 6, and a groove 7 is penetrated on the rear side of the triangular plate 2, and a control button 8 is arranged in the groove 7, and a battery box is sleeved below the groove 7, and a battery is arranged in the battery box, and the control button 8 directly controls the main gear 3, and the sub-gear 4 is rotatably connected to the inner wall of the triangular plate 2 through a rotating shaft, and the main gear 3, the sub-gear 4 and the control button 8 are electrically connected through the battery.

[0029] The main gear 3 is turned on by the control button 8. The main gear 3 drives the sub-gear 4 to rotate to one side at the same time under the transmission of the tooth pattern, and drives the two moving rods 5 to move in the moving grooves 6 respectively, so as to adjust the angle between the patient's legs and move the patient's hip joint a certain distance to prevent the patient's legs from moving during the operation and affecting the normal progress of the operation. The control button 8 is in the groove 7, so that the fixing plate 1 will not be accidentally touched when it is placed flat on the operating table.

[0030] There are two fixing mechanisms, which include an arc plate 9 and a winding drum 10. The winding drum 10 is fixedly arranged on one side of the arc plate 9, a winding rod 11 is arranged inside the winding drum 10, a fixing belt 12 is sleeved on the outer side of the winding rod 11, a positive one-way bearing 13 is sleeved on one end of the winding rod 11, a connecting block 14 is fixedly arranged on one end of the positive one-way bearing 13, a secondary one-way bearing 15 is fixedly arranged on one end of the connecting block 14, a reversing block 16 is arranged on one end of the winding drum 10, and the reversing block 16 is a T-shaped structure. A rotating block 17 is arranged on the other end of the winding drum 10.

[0031] By rotating the rotating block 17, the rotating block 17 drives the winding rod 11 to rotate in the positive one-way bearing 13. During the rotation of the winding rod 11, the fixing belt 12 is driven to reel. When the fixing belt 12 is too tightly fixed to the leg, the reversing block 16 can be rotated to make the reversing block 16 drive the connecting block 14, the positive one-way bearing 13 and the winding rod 11 to rotate simultaneously in the secondary one-way bearing 15, thereby driving the fixing belt 12 to reel in the reverse direction, thereby achieving effective fixation of the patient's leg.

[0032] The winding rod 11 is rotatably connected to the positive one-way bearing 13 , the other end of the winding rod 11 passes through the winding drum 10 and is fixedly connected to the rotating block 17 , and the other end of the reversing block 16 passes through the winding drum 10 and the secondary one-way bearing 15 and is connected to the connecting block 14 .

[0033] Since the positive one-way bearing 13 and the auxiliary one-way bearing 15 are in two different reverse directions, the winding rod 11 can be wound up with the belt fixed, thereby avoiding the problem of the fixing belt 12 being loose.

[0034] The other end of the fixing belt 12 passes through the winding drum 10 and is fixedly connected to the arc plate 9 , and a matching opening is provided at the connection between the fixing belt 12 and the winding drum 10 .

[0035] A placement groove 18 is provided on the rear side of the fixed plate 1, and a telescopic support plate 19 is provided inside the placement groove 18. The telescopic support plate 19 is hingedly connected to the placement groove 18. A lifting rope 20 is fixedly provided on the top of the fixed plate 1. Support plates 21 are fixedly provided at both ends of the fixed plate 1. The support plate 21 is an L-shaped structure, and an anti-slip pad 22 is fixedly provided on one side of the support plate 21.

[0036] By moving the telescopic support plate 19 out of the placement slot 18 and pulling the other end of the telescopic support plate 19 to contact the operating bed, a triangular support structure is formed between the support plate 21, the operating bed and the telescopic support plate 19, providing support for the patient when lying on his side and increasing stability when lying on his side.

[0037] A Velcro male patch 23 is disposed above the fixing plate 1 , and a Velcro female patch 24 is disposed above the Velcro male patch 23 . The Velcro male patch 23 and the Velcro female patch 24 are fixedly connected to the supporting plate 21 , respectively.

[0038] The waist of the patient is fixed on the fixing plate 1 by sticking the male Velcro patch 23 and the female Velcro patch 24, so that the upper body of the patient is fixed.

[0039] Working principle: When in use, the patient's legs are respectively passed through the fixing belts 12 and placed on the corresponding arc-shaped plates 9, and then the rotating block 17 is rotated so that the rotating block 17 drives the winding rod 11 to rotate in the positive one-way bearing 13. During the rotation of the winding rod 11, the fixing belt 12 is driven to reel. If the fixing belt 12 is too tightly fixed to the legs, the reversing block 16 can be rotated so that the reversing block 16 drives the connecting block 14, the positive one-way bearing 13 and the winding rod 11 to rotate simultaneously in the secondary one-way bearing 15, thereby driving the fixing belt 12 to reel in the opposite direction, thereby achieving effective fixation of the patient's legs; when the patient lies on his side, the Velcro male patch 23 and the Velcro female patch 24 are pasted to fix the patient's waist on the fixing plate 1, and the support plate 21 can be placed on the operating bed. On the upper part, cooperate with the anti-skid pad 22 to increase the friction between the operating table, then move the telescopic support plate 19 out of the placement groove 18, pull the other end of the telescopic support plate 19 to contact the operating table, so that a triangular support structure is formed between the support plate 21, the operating table and the telescopic support plate 19, which provides support for the patient when lying on his side and increases the stability when lying on his side; by turning on the control button 8 in the groove 7, the main gear 3 drives the sub-gear 4 to rotate to one side at the same time under the transmission of the tooth pattern, and drives the two moving rods 5 to move in the moving groove 6 respectively, so as to adjust the angle between the patient's legs and move the patient's hip joint a certain distance, so as to prevent the patient's legs from moving during the operation and affecting the normal progress of the operation, facilitate the subsequent operation, and is suitable for all kinds of patients.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
