Technical Field

[0001] The utility model belongs to the technical field of limb fixation equipment, in particular to a patient limb fixation frame. Background Art

[0002] During knee replacement surgery, the patient's legs need to be fixed. During traditional operations, an assistant is often required to hold the patient's lower limbs for a long time to adjust the fixed position. This method not only increases the assistant's labor intensity, but also easily leads to problems such as inaccurate positioning and poor stability, which in turn affects the surgeon's operation. Therefore, the current existing technology provides a limb fixation frame, which can fix the patient's legs to ensure the stability of the operation.

[0003] Most of the currently available limb fixation frames include a foot / ankle support and a base; the foot / ankle support is used to support the patient's foot and ankle; the base is used to be a base connected to the operating table; when in use, the base is first connected to the operating table, and then the lower limb is placed on the foot / ankle support. To ensure that the lower limb is stably located on the foot / ankle support, the current method is to use a bandage to tie the leg and foot to the foot / ankle support. Although the above method can ensure the stability of the leg and foot during the operation, the bandage needs to be wrapped and tied in circles during the fixation process, which makes it inconvenient to fix the patient's lower limb during the operation. Utility Model Content

[0004] The purpose of the utility model is to provide a patient limb fixing frame, which solves the problem of inconvenience in fixing the patient's lower limbs.

[0006] Furthermore, a rotating rod is vertically provided on the top of the splint, the upper end of the rotating rod is fixed to the bottom of the fixed sleeve, and the lower end of the rotating rod is connected to the top of the splint in a rotational fit; a limiting ring is independently sleeved on the rotating rod, and the lower end of the limiting ring is fixed to the top of the splint, and a first threaded hole communicating with the inside and outside is opened on the limiting ring, and a fastening screw threadedly matched with it is installed in the first threaded hole.

[0007] Further, the clamping assembly includes a limiting plate. The clamping plate is in a "C" - shaped structure with its opening facing backward. The limiting plate is located inside the clamping plate. A second threaded hole that communicates up and down is opened at the bottom of the clamping plate. A screw rod that is in threaded fit with it is inserted into the second threaded hole, and the upper end of the screw rod is rotatably connected to the limiting plate.

[0008] Further, a handle is fixed to the lower end of the screw rod.

[0009] Further, an airbag is installed on the inner side wall of the upper half of the fixing sleeve, and an inflation assembly for inflating it is provided on the airbag.

[0010] Further, a buffer layer is laid on the inner side wall of the lower half of the fixing sleeve.

[0020] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0021] Example

[0022] The patient limb fixation frame described in this embodiment is as follows: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the fixing sleeve 1 includes a "√"-shaped structure; the interior of the fixing sleeve 1 is a hollow structure, and the structure of the fixing sleeve 1 is designed according to the front, outer and rear areas of the lower leg, the ankle, dorsum, sole and toes of the foot, so that the patient's leg, foot and ankle can fit the fixing sleeve 1;

[0023] like Figure 1 、 Figure 4 and Figure 5 As shown, the fixing sleeve 1 is divided into two halves along its length direction, the upper and lower halves; therefore, the fixing sleeve 1 can be opened, and after the fixing sleeve 1 is opened, it is convenient to place the legs, feet and ankles in the fixing sleeve 1, so that the patient's lower limbs can be placed in the fixing sleeve 1 more easily; when in use, the upper half of the fixing sleeve 1 is first removed from the fixing sleeve 1, and because the fixing sleeve 1 is in a "√" shape, the fixing sleeve 1 has two inclined surfaces and a corner; then the patient's leg is placed on one inclined part of the fixing sleeve 1, the ankle is placed on the corner of the fixing sleeve 1, and the sole of the foot is stepped on the other inclined surface of the fixing sleeve 1, so that the patient's lower limb can be placed on the fixing sleeve 1, and then by replacing the upper half of the fixing sleeve 1 on the fixing sleeve 1, a part of the patient's lower limb can be wrapped in the fixing sleeve 1, thereby achieving the purpose of positioning the patient's legs and feet, so that the patient's legs can be placed at an angle, which is convenient for the doctor to perform the operation during knee replacement surgery and avoids the assistant from supporting the patient's legs;

[0024] like Figure 1 、 Figure 4 and Figure 5 As shown, the right ends of the upper and lower halves of the fixing sleeve 1 are hinged together and can be turned left and right; the right ends of the upper and lower halves of the fixing sleeve 1 can be hinged together by hinges or pivots; the hinges and pivots are existing known products and are therefore not described in detail; the hinged design not only makes it easy to open the upper and lower halves of the fixing sleeve 1, but also makes it easy to connect the upper and lower halves of the fixing sleeve 1 to avoid loss; when in use, the upper half of the fixing sleeve 1 can be moved away from it by swinging it from left to right, and then the upper half of the fixing sleeve 1 can be removed from it. Figure 5As can be seen from the orientation in the figure, it is convenient for the patient's lower limbs to step into the fixing sleeve 1 later. Then, by swinging the upper half of the fixing sleeve 1 back onto the lower half of the fixing sleeve 1, the purpose of wrapping the lower limbs can be achieved;

[0025] As Figure 4 shown, the left ends of the upper and lower halves of the fixing sleeve 1 are locked together by a locking component; the locking component can be a buckle 10 with different structures, such as a stainless steel flat - mouth buckle or a plug - pin buckle, etc.; the buckle generally consists of a movable part and a fixed part. The movable part can be fixed on the outer side of the left end of the upper half of the fixing sleeve 1, and the fixed part is fixed on the outer side of the left end of the lower half of the fixing sleeve 1. Then, by the combination and separation of the movable part and the fixed part, the closing and opening between the two fixing sleeves 1 can be achieved; the stainless steel flat - mouth buckle or the plug - pin buckle is a known product in the prior art and is not the improvement point of this design, so its specific structure will not be described in detail; through the design of the buckle 10, it is convenient to lock the left half of the fixing sleeve 1, making the lower limbs more stable in the fixing sleeve 1;

[0026] As Figure 1 shown, a clamping plate 4 is provided at the bottom of the fixing sleeve 1. The clamping plate 4 is used to contact the operating table and support the fixing sleeve 1;

[0027] As Figure 1 and Figure 2 shown, a limiting plate 7 is provided on the clamping plate 4. The clamping plate 4 is in a "C" - shaped structure with its opening facing backward. The limiting plate 7 is located inside the clamping plate 4. A second threaded hole that communicates up and down is opened at the bottom of the clamping plate 4, and a screw rod 6 that is in threaded fit with it is inserted into the second threaded hole. The upper end of the screw rod 6 is rotatably connected to the limiting plate 7; this section of the solution as a whole constitutes a clamping component for clamping on the operating table; when specifically implementing the rotational connection, a first blind hole can be opened at the bottom of the limiting plate 7, and a first bearing is installed in the first blind hole. The outer ring of the first bearing is fixed in the first blind hole, and the upper end of the screw rod 6 is fixed to the inner ring of the first bearing, so that the screw rod 6 can freely rotate at the bottom of the limiting plate 7 without driving the limiting plate 7 to rotate, thus achieving the rotational connection; during use, the clamping plate 4 is clamped on the bed board of the operating table, making the bed board located between the clamping plate 4 and the limiting plate 7. Then, by turning the screw rod 6 to move up and down in the threaded hole, the limiting plate 7 can be driven to move upward. During the process of the limiting plate 7 moving upward, the bed board can be clamped between the clamping plate 4 and the limiting plate 7, thus achieving the purpose of fixing the clamping plate 4 on the operating table. Since the fixing sleeve 1 is provided on the clamping plate 4, the purpose of limiting the fixing sleeve 1 on the operating table is achieved;

[0028] In the specific implementation process, the clamping component can also be a clip. One side of the clip is fixed on the clamping plate 4, and then by clamping the clip on the bed board of the operating table, the clamping plate 4 can also be driven to be limited on the bed board;

[0029] like Figure 1 and Figure 2 As shown, a handle 5 is fixed to the lower end of the screw 6. The design of the handle 5 makes it easier to rotate the screw 6.

[0030] like Figure 1 and Figure 4 As shown, a rotating rod 8 is vertically provided on the top of the splint 4, the upper end of the rotating rod 8 is fixed to the bottom of the fixed sleeve 1, and the lower end of the rotating rod 8 is rotationally matched with the top of the splint 4; a limiting ring 3 is independently sleeved on the rotating rod 8, and the lower end of the limiting ring 3 is fixed to the top of the splint 4, and a first threaded hole communicating with the inside and outside is opened on the limiting ring 3, and a fastening screw threadedly matched therewith is passed through the first threaded hole; the upper end of the rotating rod 8 is fixed to the bottom of the lower half of the fixed sleeve 1; when the lower end of the rotating rod 8 is rotationally matched, a second blind hole can be opened at the top of the splint 4, and a second bearing is installed in the second blind hole. The outer ring of the second bearing is fixed in the second blind hole, and the lower end of the rotating rod 8 is fixed to the inner ring of the second bearing. Therefore, the rotating rod 8 can be freely rotated at the top of the splint 4 because the upper end of the rotating rod 8 is fixed On the fixing sleeve 1, the fixing sleeve 1 can be driven to rotate freely, so that the angle of the fixing sleeve 1 can be adjusted during the operation, thereby increasing the practicality during use. After the rotating rod 8 drives the fixing sleeve 1 to rotate to the specified position, the fastening screw on the limiting ring 3 is tightened to make it press against the rotating rod 8, so that the rotating rod 8 rotated to the specified position can be fixed to prevent it from continuing to rotate. In knee replacement surgery, the part that needs surgery may be the patient's left lower limb or right lower limb. Therefore, when the splint 4 is clamped on the bed, it needs to be clamped at different positions on the bed board, such as the left side or the right side of the operating bed. At this time, the design that the rotating rod 8 can drive the fixing sleeve 1 to rotate makes it possible to adjust the orientation of the fixing sleeve 1 to adapt to the splint 4 clamped at different positions.

[0031] like Figure 1 and Figure 4 As shown, an air bag 9 is installed on the inner side wall of the upper half of the fixed sleeve 1, and an inflation component for inflating the air bag 9 is provided; the inner side wall of the upper half of the fixed sleeve 1 is Figure 1The bottom of the upper half of the middle fixing sleeve 1; the inflation component can be an air pump, and the upper half of the fixing sleeve 1 is provided with a first through-hole communicating with the inside and outside, and the trachea on the air pump is connected to the airbag 9 through the first through-hole; therefore, the air pump can inflate the airbag 9, and after the air pump inflates the airbag 9, when the patient's legs and feet are placed in the fixing sleeve 1 and restricted, the expansion of the airbag 9 can make the patient's legs and feet more stably restricted in the fixing sleeve 1, and the doctor improves the surgical accuracy during the operation; in the specific implementation process, the inflation component can also be the trachea 11 and the squeezing balloon 12; the upper half of the fixing sleeve 1 is provided with a second through-hole communicating with the inside and outside, one end of the trachea 11 is connected to the airbag 9 through the second through-hole, and the other end is connected to the squeezing balloon 12 The squeezing balloon 12 is usually made of rubber material and is light and soft. A one-way valve is provided on the squeezing balloon 12 to ensure that air can only flow from the inflatable ball to the airbag, but not in the opposite direction. When in use, the airbag 9 can be inflated by pressing the squeezing balloon 12. During the inflation process, the operator controls the amount of air entering the airbag 9 by controlling the squeezing force and frequency of the squeezing balloon 12, thereby controlling the pressure in the airbag 9. The cooperation between the trachea 11 and the squeezing balloon 12 is an existing known method. For example, the blood pressure monitor around us adopts this technology. There is an airbag in the cuff of the blood pressure monitor, and the airbag is inflated through the trachea 11 and the squeezing balloon 12 to expand it, thereby applying pressure to the blood vessels in the cuff.

[0032] like Figure 1 As shown, a buffer layer is laid on the inner side wall of the lower half of the fixing sleeve 1, and the buffer layer is a sponge pad 2; the inner side wall of the lower half of the fixing sleeve 1 is Figure 1 The sponge pad 2 can be placed on the top of the lower half of the fixing sleeve 1, and then the sponge pad 2 can be directly pressed into the lower half of the fixing sleeve 1 with the legs and feet, which not only maintains the stability of the sponge pad 2 but also facilitates the removal of the sponge pad 2; the sponge pad 2 can also be adhered to the lower half of the fixing sleeve 1 with glue, and the glue can be AB glue, which can be easily torn off without leaving glue liquid, such as the chest stickers around us. The design of the sponge pad 2 allows the patient's legs and feet to be placed more comfortably in the fixing sleeve 1; in the specific implementation process, the buffer layer can also be cotton;

[0033] In the specific use process: first clamp the splint 4 on the operating table, then drive the limit plate 7 to move by screwing the screw 6 to fix the splint 4 on the operating table, and then Figure 5 Position the patient in the middle position, turn the upper part of the fixing sleeve 1 upwards, then place the patient's lower limbs on the lower part of the fixing sleeve 1, and then turn the fixing sleeve 1 to Figure 4The upper and lower halves of the fixing sleeve 1 are locked together by the lock buckle 10, so that the patient's legs and feet can be restricted in the fixing sleeve 1, thereby achieving the purpose of fixing the patient's legs and feet, avoiding the problem of cumbersome operation caused by wrapping the straps around in circles in the prior art. Therefore, this design is convenient for fixing the lower limbs, and is convenient for doctors to operate during knee replacement surgery.
