Description

Technical Field

[0001] The present application relates to the field of medical auxiliary equipment, and in particular to a lower limb fixation device. Background Art

[0002] Hepatic artery embolization is a procedure that uses the Seldinger technique to perform percutaneous femoral artery puncture, super-selectively cannulate the hepatic artery branch, and inject embolic agents to control the growth or rupture of liver cancer, cause ischemia, necrosis or shrinkage of the tumor, or relieve local and systemic symptoms.

[0003] After the hepatic artery embolization surgery, a drug delivery catheter will be placed in the right lower groin of the patient for continuous drug delivery. Within 72 hours, the lower limbs need to be restricted and cannot compress the drug delivery catheter. Therefore, the patient's lower limbs should not be able to lift the legs or bend during this period. Since the lower limbs cannot move for a long time, it is also necessary to regularly observe the arterial pulsation of the right lower limb. Now, some lower limb straps or lower limb protective gear are usually used to restrain the patient's lower limbs, but these methods have some shortcomings. The lower limb straps are relatively soft and have a certain elasticity. After being tied, the patient's lower limbs can still move to a certain extent. The straps may be loosened due to the movement of the lower limbs, resulting in an increase in the range of motion of the patient's lower limbs; the structure of the lower limb protective gear is usually a bracket for placing the patient's lower limbs, and more straps are set on the bracket. This lower limb protective gear can only restrict the range of motion of the knee joint, but cannot restrict the range of motion of the hip joint. The patient may also move the hip joint and compress the drug delivery catheter. Secondly, the lower limb protective gear with a bracket structure is easily worn and in contact with the skin for a long time, and pressure sores are easily formed on the body surface. Utility Model Content

[0004] The technical problem to be solved by the present application is to provide a lower limb fixation device which can restrain the patient's lower limbs from swinging freely and avoid the formation of pressure sores.

[0005] In order to solve the above technical problems, this application adopts the following technical solutions:

[0006] A lower limb fixing device comprises a waist belt, a fixing plate is provided on the side of the waist belt, a fixing piece is provided on the fixing plate, a telescopic rod is detachably connected to the side of the fixing piece, and a limiting assembly is sleeved on the telescopic rod. The waist belt is sleeved on the patient's waist, and the height of the telescopic rod is fixed by the fixing plate, and then the lower limb is placed under the limiting assembly and fixed, the patient's lower limb knee joint is blocked by the limiting assembly and cannot bend, and the telescopic rod is fixed on the fixing plate, which also makes the hip joint unable to move, thereby restricting the patient's lower limb movement.

[0007] According to the further development of the above scheme, the fixing plate includes a bottom plate and side plates, the bottom plate and the side plates are 90°, and the waist belt is arranged at the angle of the fixing plate. When the patient lies on the bed, the bottom plate is pressed to fix the fixing plate, and the telescopic rod can also be fixed at the same time.

[0008] According to a further development of the above solution, the fixing part is a magnetic table stand.

[0009] According to a further development of the above scheme, a threaded sleeve is provided on the right end face of the fixing member, and the telescopic rod and the threaded sleeve are threadedly connected, so that the lower limb fixing device can be assembled and used, or disassembled and stored as needed.

[0010] In order to enable the limiting assembly to move the lower limbs of patients with lower limbs, the above-mentioned scheme is further expanded, and the limiting assembly includes a sleeve, a limiting bolt, a limiting plate and a strap. The sleeve is sleeved on the telescopic rod, and a threaded hole is provided on the side wall of the sleeve, and a limiting bolt is provided in the threaded hole; a limiting plate is also provided on the side of the sleeve, and a strap is connected to the end of the limiting plate away from the sleeve.

[0011] According to a further development of the above scheme, the middle portion of the limiting plate is arched upward to fit the shape of the lower limb.

[0012] According to a further development of the above scheme, the telescopic rod and the foot support plate are connected by a hinge connection. When the patient wears the foot support plate, the ankle can be movable, thereby reducing blood embolism.

[0013] According to the further development of the above scheme, the end of the telescopic rod away from the fixing piece is connected to a foot support plate, the foot support plate is provided with an elastic band, and the elastic band is provided with a detector for detecting the dorsalis pedis artery of the patient. The detector can be a blood sample detector or an artery detector.

[0014] Compared with the prior art, the present application achieves at least the following beneficial effects: the present device constrains the knee joint of the lower limb by arranging a limit assembly on the telescopic rod, and then fixes the telescopic rod on the fixing plate. When the knee joint cannot move, the hip joint movement is constrained by the telescopic rod combined with the limit assembly, thereby realizing the restriction of the mobility of the patient's lower limbs and preventing the patient from moving the lower limbs and compressing the drug delivery catheter placed in the groin; compared with the existing lower limb protective gear, the present device can fix the lower limbs without the need for a bracket structure, reducing the risk of pressure sores caused by long-term contact of some components with the skin.

[0019] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0020] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0021] The inventors have made a careful analysis and found that the main reason for the above problems in the existing method of fixing the patient's lower limbs is that the rope-structured straps are used to bind the patient's lower limbs, and then one end of the straps is tied to the bedside. This method has a greater lateral restraining effect on the lower limbs. If the lower limbs are swung upward, the restraining force will be reduced (refer to the restraints used by mental patients), causing the lower limbs to move slightly. During the movement, because the lower limbs are not complete cylindrical structures, the straps may move during the movement of the lower limbs, causing the straps to loosen, and ultimately increasing the patient's lower limb mobility. The lower limb brace can only be fixed to the knee joint of the lower limb. When the patient is in bed, the knee joint bends, and the thigh and hip also bend to a certain extent. Therefore, the lower limb brace may not be able to fix the hip joint, that is, it cannot limit the movement of the thigh. Secondly, the lower limb brace usually uses a bracket to wrap the back of the thigh and calf, and then sets multiple straps on the side of the bracket for binding and fixing. For hepatic artery embolization surgery, it needs to be worn for a long time. The lower limbs and the bracket are in contact for a long time, and the patient cannot normally perceive the discomfort of the body, which is easy to cause pressure sores or blood circulation. Based on the above analysis, the inventor has made structural improvements to the device for restraining the patient's lower limbs.

[0022] like Figure 1 As shown, in one embodiment of the lower limb fixing device of the present application, the device comprises a waist belt 1, a fixing plate is provided on the side of the waist belt 1, a fixing member 4 is provided on the fixing plate, a telescopic rod 6 is detachably connected to the side of the fixing member 4, a limiting assembly 7 is sleeved on the telescopic rod 6, and a foot support plate 8 is connected to the end of the telescopic rod 6 away from the fixing member 4, and an elastic band 9 is provided on the foot support plate 8. When using the device, the waist belt 1 is sleeved on the patient's waist, the tightness is adjusted, the height of the telescopic rod 6 is fixed by the fixing plate, the telescopic rod 6 is arranged on the side of the lower limb, and then the lower limb is placed under the limiting assembly 7 and fixed, and finally the patient's foot is sleeved on the foot support plate 8, the patient's lower limb knee joint is blocked by the limiting assembly 7 and cannot bend, the telescopic rod 6 is fixed on the fixing plate, and the fixed telescopic rod 6 combined with the fixing assembly 7 makes the hip joint unable to move, thereby restricting the patient's lower limb movement.

[0023] The fixing plate is used to fix the telescopic rod 6. Therefore, the fixing plate needs to be pressed by a certain gravity to prevent it from moving. The fixing plate includes a bottom plate 2 and a side plate 3. The bottom plate 2 and the side plate 3 are arranged at a right angle of 90°. The waist belt 1 is arranged at the angle of the fixing plate. The bottom surface of the waist belt 1 and the top surface of the bottom plate 2 are fitted and connected. The side surface of the waist belt 1 and the back surface of the side plate 3 are fitted and connected. The fitting connection can be connected by glue, Velcro, etc. When the patient lies on the bed, the bottom plate 2 can be pressed by gravity to press the fixing plate, and the telescopic rod 6 can also be fixed to prevent it from swinging.

[0024] The fixing member 4 serves as an intermediate component for connecting the fixing plate and the telescopic rod 6, and is also used to adjust the height of the telescopic rod 6 so that the telescopic rod 6 can be adjusted to a height that matches the side of the patient's lower limb. Therefore, the fixing member 4 uses a magnetic table seat, and the fixing plate is made of metal. When the magnetic table seat is adjusted to generate magnetism, it fits and fixes the front end surface of the side plate 3 of the fixing plate; when magnetism is not generated, it can be removed from the side plate 3. In addition, the front end surface of the side plate 3 is also provided with a vertical groove for placing the fixing member 4. The guidance of the vertical groove can ensure the parallelism of the fixing member 4 and quickly adjust the height of the fixing member 4.

[0025] The right end face of the fixing member 4 is fixedly connected with a threaded sleeve 5, and the left end outer wall of the telescopic rod 6 is provided with a thread, which is threadedly connected to the threaded sleeve 5, so that the lower limb fixing device can be assembled and used, or disassembled and stored as needed.

[0026] In order to enable the limiting assembly 7 to move the lower limbs of the patient, the Figure 1 and Figure 2As shown, the structure of the limit assembly 7 includes a sleeve 7-1, a limit bolt 7-2, a limit plate 7-3 and a bandage 7-4. The sleeve 7-1 is sleeved on the telescopic rod 6. The side wall of the sleeve 7-1 is provided with a threaded hole, and the limit bolt 7-2 is provided in the threaded hole. The side of the sleeve 7-1 is also welded with a limit plate 7-3, and the end of the limit plate 7-3 away from the sleeve 7-1 is connected with a bandage 7-4. Among them, a through hole (not shown) is provided at the connection between the limit plate 7-3 and the sleeve 7-1, and the bandage 7-4 can extend from the through hole from bottom to top. In addition, Velcro is provided on the top surface of the limit plate 7-3 and the end surface of the bandage 7-4, respectively. When the bandage 7-4 passes through the through hole, it is fixed by the Velcro at the two locations to prevent it from loosening. The number of limit assemblies 7 on the telescopic rod 6 is not limited to one. When in use, the sleeve 7-1 is sleeved on the telescopic rod 6, so that the limiting plate 7-3 is placed on the corresponding position of the patient's lower limbs, and then the strap 7-4 is wrapped around the lower limbs downward, and passed through the through hole at the connection between the limiting plate 7-3 and the sleeve 7-1 and slightly tightened, and fixed with Velcro, and finally the limiting bolt 7-2 is tightened to prevent the limiting plate 7-3 from rotating, so as to fix the patient's lower limbs. Since the patient lies down with his lower limbs, the lower limbs can only swing upwards but not downwards. Therefore, the strap 7-4 does not need to be tied too tightly, and it only needs to limit the lower limbs from swinging along the bed surface.

[0027] The middle part of the limiting plate 7-3 is arched upward, roughly in the shape of a tile, so as to fit the shape of the lower limb.

[0028] The connection between the telescopic rod 6 and the foot support plate 8 is a hinge connection. When the patient wears the foot support plate 8, the ankle can be moved, reducing the occurrence of blood embolism. The foot support plate 8 is a plate made of metal or plastic with a certain thickness, and a through hole is opened on its end surface. One end of the telescopic rod 6 passes through the through hole, and a cylindrical pin passes through the through hole and the telescopic rod 6 to connect the telescopic rod 6 and the foot support plate 8. The through hole on the foot support plate 8 is larger than the outer diameter of the telescopic rod 6, so that the foot support plate 8 can swing on the telescopic rod 6 at a certain angle.

[0029] The function of the elastic band 9 is to fix the patient's foot on the foot support plate 8. The existing dorsalis pedis artery detection method is that the doctor touches the pulsation of the patient's dorsalis pedis artery with his hand. In order to reduce the doctor's frequent detection work intensity and ensure that the patient's dorsalis pedis artery can be detected regularly, the elastic band 9 is provided with a detector (not shown) for detecting the patient's dorsalis pedis artery. The detector can be a blood sample detector or an artery detector. The elastic band 9 is tied around the patient's dorsum of the foot so that the detector fits the dorsalis pedis artery.
