Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an anti-foot-drop device for a Brown traction frame. Background Art
[0002] The Brown traction frame realizes bone traction or skin traction through a pulley system, and is used for reducing fractures and dislocations, maintaining the position after reduction, correcting joint deformities, and relieving muscle spasm and pain. It is applicable to lower limb traction, ankle bone traction, femoral traction, etc., and is an important tool for orthopedic lower limb fracture traction conditioning.
[0003] In the actual operation process, through the cooperation of the traction rope and the pulley, the patient's leg can be in a suspended state. During the traction process, the patient's toes will tilt away from the patient's leg. And due to the long traction process, it is easy to cause the patient to form foot drop, simply called foot drop. Therefore, during the patient's rehabilitation process, clothes or soft items are used to pad under the patient's heel to reduce the tilt of the patient's foot. However, although this method can avoid the phenomenon of foot drop to a certain extent, it will cause the traction weight of the traction frame to disappear, resulting in the failure of the traction work.
[0004] Therefore, how to avoid the symptom of foot drop in patients when using the Brown traction frame is a problem to be solved at present. Summary of the Utility Model
[0005] Utility Model Purpose: To provide an anti-foot-drop device for a Brown traction frame to solve the above problems existing in the prior art.

[0008] In a further embodiment, the adjusting member includes a second fixing pin screwed to the adjusting frame, and the other end of the second fixing pin is connected to the foot placement seat.
[0009] In a further embodiment, the first limiting sleeve and the second limiting sleeve have a predetermined elasticity;
[0010] When the patient wears it, the inner walls of the first limiting sleeve and the second limiting sleeve are respectively in contact with the patient's leg and foot.
[0011] In a further embodiment, one end of the leg placement seat close to the patient's foot is provided with a C-shaped protective sleeve, and a buffer pad provided on the protective sleeve.

[0019] After research and analysis by the applicant, the reason for this problem (avoiding foot drop symptoms in patients when using a Brown traction frame) is that in the actual operation process, through the cooperation of the traction rope and the pulley, the patient's leg can be in a suspended state. During traction, the patient's toes will tilt away from the patient's leg. Since the entire traction process is too long, it is easy for the patient to develop foot drop, simply referred to as foot drop. Therefore, during the patient's rehabilitation process, clothes or soft items are used to pad under the patient's heels to reduce the tilt of the patient's foot. Although this method can avoid the phenomenon of foot drop to a certain extent, it will cause the traction weight of the traction frame to disappear, resulting in the failure of the traction work. In order to avoid foot drop symptoms in patients when using a Brown traction frame, this device is provided with a leg placement seat, a connection seat provided on the leg placement seat, a first fixing pin movably connected to the connection seat, a rotating disk movably connected to the free end of the first fixing pin, an adjusting frame connected to the rotating disk, an adjusting member provided on the adjusting frame, a foot placement seat connected to the adjusting member, a first limiting sleeve provided on the leg placement seat, and a second limiting sleeve provided on the foot placement seat. By sleeving the first limiting sleeve and the second limiting sleeve on the patient's leg and foot respectively, then the medical staff rotates the first fixing pin, and then rotates the adjusting frame, so that the patient's foot can present a predetermined posture, and then rotates the first fixing pin in the reverse direction, so that the adjusting frame is in a fixed state. Since in this process, this device does not contact the bed surface of the Brown traction frame, the traction weight is ensured to always exist, so that while avoiding foot drop symptoms in patients, the patient can also be subjected to traction work.
[0020] An anti-foot-drop device for a Brown traction frame, comprising: a leg placement seat 1, a protective sleeve 2, a buffer pad 3, a connection seat 4, a first fixing pin 5, a second limiting sleeve 6, a rotating disk 7, an adjusting frame 8, a second fixing pin 9, a foot placement seat 10, and a first limiting sleeve 11.
[0021] The device includes a leg placement seat 1, a connecting seat 4 provided on the leg placement seat 1, a first fixing pin 5 movably connected to the connecting seat 4, a rotating disk 7 movably connected to the free end of the first fixing pin 5, an adjusting frame 8 connected to the rotating disk 7, an adjusting member provided on the adjusting frame 8, a foot placement seat 10 connected to the adjusting member, a first limiting sleeve 11 provided on the leg placement seat 1, and a second limiting sleeve 6 provided on the foot placement seat 10; by sleeving the first limiting sleeve 11 and the second limiting sleeve 6 on the patient's leg and foot respectively, then the medical staff rotates the first fixing pin 5, and then rotates the adjusting frame 8, so that the patient's foot can present a predetermined posture, and then rotates the first fixing pin 5 in the reverse direction, so that the adjusting frame 8 is in a fixed state. Since during this process, the device does not contact the surface of the Brown traction frame, the traction weight always exists, so that while avoiding the occurrence of foot drop symptoms in the patient, the traction work can also be carried out on the patient.
[0022] In the first embodiment, the adjusting member includes a second fixing pin 9 screwed to the adjusting frame 8, and the other end of the second fixing pin 9 is connected to the foot placement seat 10; by providing the second fixing pin 9, the angle between the foot placement seat 10 and the adjusting frame 8 can be adjusted, which is convenient for placing the feet of the patient with slight deformation.
[0023] In the second embodiment, the first limiting sleeve 11 and the second limiting sleeve 6 have a predetermined elasticity; when the patient wears it, the inner walls of the first limiting sleeve 11 and the second limiting sleeve 6 are respectively in contact with the patient's leg and foot; by making the first limiting sleeve 11 and the second limiting sleeve 6 have a predetermined elasticity, the fixing work of the legs and feet of patients with different sizes can be achieved, and the device can be prevented from falling off the patient's leg.
[0024] In the third embodiment, one end of the leg placement seat 1 close to the patient's foot is provided with a C-shaped protective sleeve 2, and a buffer pad 3 provided on the protective sleeve 2; the protective sleeve 2 is a variable-diameter tubular structure; when correcting the placement position of the patient's foot, the calf part of the patient will bend towards the direction close to the placement surface of the traction frame, and through the provided buffer pad 3 and variable-diameter tubular structure, the smooth progress of the patient's leg placement work is ensured.
[0025] In the fourth embodiment, a limiting plate is further provided on the foot placement seat 10, which is in contact with the patient's heel.
[0026] Working principle description: By rotating the second fixing pin 9, the angle between the foot placement seat 10 and the adjusting frame 8 can be adjusted, facilitating the placement of the patient's foot after slight deformation; then the first limiting sleeve 11 and the second limiting sleeve 6 are respectively sleeved on the patient's leg and foot, and then the medical staff rotates the first fixing pin 5 and then rotates the adjusting frame 8, so that the patient's foot can assume a predetermined posture, and then rotates the first fixing pin 5 in the reverse direction, so that the adjusting frame 8 is in a fixed state. Since during this process, this device does not contact the surface of the Brown traction frame, the traction weight always exists, thus while avoiding the occurrence of foot drop symptoms in the patient, the traction work can also be carried out on the patient.
[0027] As described above, although the present utility model has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present utility model itself. Various changes in form and details can be made without departing from the spirit and scope of the present utility model defined by the appended claims.
