Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to an ice pack device for fixing the angle after knee joint surgery. Background Technology
[0002] The knee joint is the most complex joint in the human body, with the strongest leverage and the most vulnerable to injury. Moreover, knee joint damage is irreversible. For severe knee osteoarthritis, total knee replacement surgery is required. Knee replacement surgery can relieve knee pain, improve knee function, correct knee deformities, and achieve long-term stability.
[0003] After knee replacement surgery, patients need to apply cold compresses to their knees. Cold compresses help relieve pain and promote healing. For knee replacement patients, timely application of ice is crucial. It effectively reduces histamine release, decreases tissue sensitivity to pain, and reduces microcirculation and surrounding tissue exudation and swelling. Ice application should begin as early as possible and continue for a period of time. Currently available cold compress devices mostly use towels. This method has poor continuity, requiring frequent towel changes, which increases the workload of medical staff, reduces the effectiveness of the cold compress, and makes it difficult to adjust the cooling intensity according to the patient's needs. This poor applicability is detrimental to patient recovery.
[0004] In addition, knee fixation braces are often used in the treatment of knee joint injuries to fix the flexion angle of the knee joint, providing auxiliary support for the injured knee during rehabilitation, reducing the body pressure on the knee joint, and adjusting the flexion angle of the knee joint according to the recovery progress to adapt to the pressure that the knee joint can withstand, thereby assisting the effectiveness of surgical treatment and ensuring rapid knee joint recovery. However, existing knee fixation braces cannot achieve ice application to the patellar surface of the knee. When using a knee fixation brace, it is necessary to manually press and apply ice packs or towels to the patellar surface, which is cumbersome and labor-intensive. Utility Model Content
[0005] In view of the above, it is necessary to provide a knee joint postoperative angle fixation ice pack device. This device can be used to fix the knee joint angle alone or to apply ice packs alone, depending on the recovery status and treatment needs. It can also apply ice packs while fixing the knee joint angle.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a postoperative knee joint angle fixation ice pack device, comprising two fixation sleeves respectively fitted on the upper and lower sides of the knee joint, the two fixation sleeves being spaced apart and rotatably connected by a rotating mechanism, the rotating mechanism being provided with a locking member to prevent the two fixation sleeves from rotating, and each of the fixation sleeves being slidably connected to the rotating mechanism in the length direction of the fixation sleeve; an ice pack sleeve for placing an ice pack is detachably connected between the two fixation sleeves, the two sides of the ice pack sleeve in the width direction being detachably connected to the fixation sleeves respectively, and a connector for wearing the ice pack sleeve on the knee area in the length direction of the ice pack sleeve.
[0007] Furthermore, the rotating mechanism consists of two rotatably connected connecting rods, and the locking element includes a screw and a locking nut; one connecting rod is correspondingly connected to one fixed sleeve, and the rotatable connection of the two connecting rods is located between the two fixed sleeves. The rotation axis of the rotatable connection is perpendicular to the length direction of the fixed sleeve and the length direction of the connecting rod; the screw is coaxially mounted on the rotation axis, one end of the screw is fixedly connected to one of the connecting rods, and the other end movably passes through the other connecting rod and extends to the outer side of the other connecting rod away from the ice pack sleeve, and the locking nut is threadedly connected to the outer side of the other connecting rod. The locking nut abuts against the connecting rod or moves away from the connecting rod by rotating the screw through the thread on the screw.
[0008] Furthermore, a guide block is provided on the outer side of the fixed sleeve, and a guide groove is provided on the guide block for the connecting rod to slide. A fixing member is provided on the guide block to prevent the fixed sleeve from sliding relative to the connecting rod. The fixing member is a locking screw. One end of the locking screw is located on the outer side of the guide block away from the fixed sleeve, and the other end is threaded through the guide block and extends into the guide groove. The locking screw rotates relative to the thread of the guide block to abut against the connecting rod.
[0009] Furthermore, the two fixed sleeves are connected by two rotating mechanisms, which are respectively located on both sides of the fixed sleeves in the radial direction.
[0010] Furthermore, the cross-section of the fixation sleeve is arc-shaped, and a first fixation strap for fixing the fixation sleeve to the patient's leg is installed at the opening of the arc.
[0011] Furthermore, each fixed sleeve is detachably connected to an inner sleeve, which is made of a soft material.
[0012] Furthermore, the ice pack sleeve includes an inner layer, an outer layer, and a waterproof layer, with the waterproof layer located between the inner and outer layers.
[0013] Furthermore, the inner layer is made of a water-absorbing material; the outer layer is made of a skin-friendly material.
[0014] Furthermore, the ice pack sleeve is provided with two connectors, which are connecting straps. One end of the connecting strap is a fixed end, and the other end is a movable end. The fixed ends of the two connecting straps are connected to both sides of the ice pack sleeve along the radial direction of the fixed sleeve, and the movable ends of the two connecting straps are detachably connected to each other.
[0015] Furthermore, the ice pack sleeve is detachably connected to the fixing sleeve via a second fixing strap.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This utility model includes two fixing sleeves respectively fitted onto the upper and lower sides of the knee joint. The two fixing sleeves are spaced apart and rotatably connected by a rotating mechanism. The rotating mechanism is equipped with a locking element to prevent the two fixing sleeves from rotating. Under the action of the rotating mechanism, the relative angle between the two fixing sleeves can be adjusted, thereby adjusting the knee joint to a certain angle. Under the action of the locking element, the two fixing sleeves are kept at the corresponding angle, thereby fixing the bending angle of the knee joint. In addition, this utility model has an ice pack sleeve for placing an ice pack detachably connected between the two fixing sleeves. This allows for selective fixation of the knee joint angle and application of ice packs, depending on the recovery status and treatment needs. Alternatively, ice packs can be applied simultaneously with knee joint angle fixation, eliminating the need for manual pressing and application of ice packs or towels, simplifying operation and saving manpower.
[0018] 2. The two fixing sleeves fitted on the upper and lower sides of the knee joint are slidably connected to the rotating mechanism. The sliding direction is the length direction of the fixing sleeve. The sliding direction of the fixing sleeve can be adjusted according to the leg length of different patients, thereby adjusting the interval between the two fixing sleeves to accommodate patients with different leg lengths.

[0027] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation
[0028] Please see Figures 1-4 In a preferred embodiment of this utility model, a postoperative knee joint angle fixation ice pack device includes two fixation sleeves 1 respectively fitted on the upper and lower sides of the knee joint. The two fixation sleeves 1 are spaced apart and rotatably connected by a rotating mechanism. The rotating mechanism is provided with a locking member to prevent the two fixation sleeves 1 from rotating. Under the action of the rotating mechanism, the relative angle between the two fixation sleeves 1 can be adjusted, thereby adjusting the knee joint to a certain angle. Under the action of the locking member, the two fixation sleeves 1 maintain the corresponding angle, thereby fixing the bending angle of the knee joint. Preferably, the rotating mechanism consists of two rotatably connected connecting rods 21, with one connecting rod 21 corresponding to one fixed sleeve 1. The rotatable connection of the two connecting rods 21 is located between the two fixed sleeves 1. The rotation axis of the rotatable connection is perpendicular to the length direction of the fixed sleeve 1 and the length direction of the connecting rod 21. The rotation of the connecting rod 21 can drive the fixed sleeve 1 on it to rotate synchronously. In addition, the locking component includes a screw 31 and a locking nut 32. The screw 31 is coaxially mounted on the rotating axis. One end of the screw 31 is fixedly connected to one of the connecting rods 21, and the other end movably passes through the other connecting rod 21 and extends to the outer side of the other connecting rod 21 away from the ice pack sleeve 4. The locking nut 32 is threadedly connected to the outer side of the other connecting rod 21. The locking nut 32 abuts against the connecting rod 21 or moves away from the connecting rod 21 by rotating the thread on the screw 31. After the two connecting rods 21 have rotated to a certain angle, rotate the locking nut 32 so that the locking nut 32 abuts against the connecting rod 21 under the action of the thread rotation. At this time, the rotation between the two connecting rods 21 is locked, and the relative angle between the fixing sleeves 1 on the two connecting rods 21 is also fixed. When it is necessary to adjust the angle again, simply rotate the locking nut 32 in the opposite direction to move it away from the connecting rod 21 to release the lock.
[0029] Furthermore, each fixed sleeve 1 is slidably connected to the rotating mechanism, with the sliding direction being the length direction of the fixed sleeve 1. The sliding direction of the fixed sleeve 1 can be adjusted according to the leg length of different patients, thereby adjusting the interval between the two fixed sleeves 1 to accommodate patients with different leg lengths. Preferably, in this embodiment, the fixed sleeve 1 is slidably connected to the rotating mechanism through the following structure: a guide block 11 is provided on the outer side of the fixed sleeve 1, and a guide groove 111 is provided on the guide block 11 for the connecting rod 21 to slide. The fixed sleeve 1 is slidably mounted on the rotating mechanism through the sliding connection between the guide groove 111 and the connecting rod 21. In addition, a fixing member is provided on the guide block 11 to prevent the fixed sleeve 1 from sliding relative to the connecting rod 21. The fixing member is a locking screw 112. One end of the locking screw 112 is located on the outer side of the guide block 11 away from the fixed sleeve 1, and the other end is threaded through the guide block 11 and extends into the guide groove 111. The locking screw 112 abuts against the connecting rod 21 through the threaded rotation of the locking screw 112 relative to the guide block 11. When the fixed sleeve 1 slides to the corresponding position of the connecting rod 21, rotating the locking screw 112 to abut against the connecting rod 21 can prevent the fixed sleeve 1 from sliding relative to the connecting rod 21. The distance between the two connecting sleeves can be adjusted by using the same method to adjust the sliding positions of the two fixed sleeves 1 relative to the connecting rod 21. When it is necessary to readjust the distance between the two connecting sleeves, rotating the locking screw 112 in the opposite direction away from the connecting rod 21 can release the fixation, at which point the fixed sleeve 1 can slide relative to the connecting rod 21. Preferably, in this embodiment, the two fixed sleeves 1 are connected by two rotating mechanisms, which are respectively located on both sides of the fixed sleeve 1 in the radial direction. By setting two rotating mechanisms, the relative angle between the two fixed sleeves 1 can be adjusted more stably. In addition, the fixed sleeve 1 is simultaneously slidably connected to the rotating mechanisms on both sides, making the sliding adjustment more stable.
[0030] Preferably, the cross-section of the fixing sleeve 1 is arc-shaped, and a first fixing strap 12 for fixing the fixing sleeve 1 to the patient's leg is installed at the opening of the arc. The arc shape fits the patient's leg better and makes it easier to insert the patient's thigh or calf into the fixing sleeve 1 through the arc opening. The first fixing strap 12 can fix the fixing sleeve 1 to the patient's leg and prevent the fixing sleeve 1 from falling off. In addition, in this embodiment, the first fixing strap 12 can be fixed to the fixing sleeve 1 by knotting or Velcro connection, etc., and those skilled in the art can choose according to the actual situation. More preferably, each fixing sleeve 1 has a detachable inner sleeve 13. The inner sleeve 13 is made of a soft material, such as cotton or sponge. The inner sleeve 13 separates the patient's skin from the fixing sleeve 1, which can enhance the patient's comfort.
[0031] Furthermore, in order to apply ice while fixing the knee joint angle to relieve pain and promote healing, this invention includes an ice pack sleeve 4 detachably connected between the two fixing sleeves 1 for placing an ice pack. The ice pack sleeve 4 is detachably connected to the fixing sleeves 1 on both sides in the width direction. Preferably, the ice pack sleeve 4 is detachably connected to the fixing sleeves 1 via a second fixing strap 41. In this embodiment, it is preferable to detach the fixing sleeves 1 by moving the second fixing strap 41 through the fixing sleeve 1 and then detachably connecting it to the strap body via Velcro. Alternatively, the ice pack sleeve 4 can be detachably connected to the fixing sleeves 1 by tying a knot or directly attaching the second fixing strap 41 to the fixing sleeve 1 via Velcro. Additionally, the ice pack sleeve 4 has a connector in the length direction for wearing the ice pack sleeve 4 on the knee. When fixing the knee joint angle, if it is necessary to apply ice to the knee joint at the same time, an ice pack sleeve 4 can be connected between two fixing sleeves 1. The ice pack sleeve 4 has an opening on the side that does not fit the skin, through which the ice pack can be placed into the ice pack sleeve 4. Then, the opening is sealed with a zipper. After that, the knee joint angle is adjusted and fixed using the method mentioned above. Then, the connection of the second fixing strap 41 is adjusted to adjust the connection distance between the ice pack and the fixing sleeve 1. Then, the ice pack sleeve 4 is fixed to the patellar surface of the knee using a connector, thereby achieving the purpose of applying ice while fixing the knee joint angle. Depending on the recovery of the injury, if only knee joint angle fixing is needed, the ice pack sleeve 4 can be removed and knee joint angle fixing can still be performed alone. If only ice is needed, the ice pack sleeve 4 can be removed from the fixing sleeve 1, the fixing sleeve 1 can be removed from the patient's leg, and only the ice pack sleeve 4 can be fixed to the patellar surface of the knee for ice application.
[0032] Preferably, the ice pack sleeve 4 includes an inner layer, an outer layer, and a waterproof layer, with the waterproof layer located between the inner and outer layers. The waterproof layer can prevent condensation from the melting ice pack from seeping through the ice pack sleeve 4 and wetting the patient. In this embodiment, the inner layer is made of absorbent material, such as cotton or a super absorbent polymer sponge, which can quickly absorb the condensation produced by the melting of the ice pack, further preventing the condensation from seeping through the ice pack sleeve 4 and wetting the patient. The outer layer is made of skin-friendly material, preferably cotton cloth, which can increase the comfort of the patient's skin in contact with the ice pack and prevent frostbite. More preferably, the ice pack sleeve 4 is provided with two connectors, which are connecting straps 42. One end of the connecting strap 42 is a fixed end, and the other end is a movable end. The fixed ends of the two connecting straps 42 are connected to both sides of the ice pack sleeve 4 along the radial direction of the fixed sleeve 1. The movable ends of the two connecting straps 42 are detachably connected to each other. The free ends of the two connecting straps 42 can be detachably connected by knotting or by Velcro. Those skilled in the art can also use other methods to detach them. The detachable connection method is not the focus of this application and will not be described here.
[0033] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
