Description

An adjustable traction brace for lower extremity fractures on an electric bed

technical field

The utility model belongs to the technical field of medical devices and relates to a fracture traction brace, in particular to an adjustable electric bed lower limb fracture traction brace.

Background technique

Bone traction is one of the orthopedic treatment methods for fracture reduction, fixation and many other orthopedic diseases, especially for patients who are not suitable for surgery, the purpose of treatment can be achieved through traction; while lower limb bone traction is to use traction and counter traction to act on fractures. The treatment method to achieve reduction or maintain reduction and fixation. Clinically, many patients with lower extremity fractures need to use traction frames for bone traction to achieve preoperative limb fixation, prevent secondary damage to blood vessels and nerves caused by fractures, and create the best timing for surgery. Existing traction frames for lower extremities mainly include Thomas traction frame and Brown's traction frame. These traction frames for lower extremity fractures have the following problems: (1) the traction frame needs a special traction bed, and the volume is large and the cost is high; (2) in the Changes in the patient's position during operation and nursing, such as changing sheets, urinating and defecating, etc., may easily cause changes in traction, and the continuous effectiveness of traction cannot be guaranteed; Adjust to affect the traction effect.

Patients with multiple clinical injuries need to be admitted to the intensive care unit due to multiple organ injuries that may be life-threatening and unstable breathing cycle. At present, the electric bed in the intensive care unit does not have the special traction function for orthopedics. In order to meet the needs of patients, often The traction support consists of self-made locks, support rods and pulleys. The locks are used to fix the traction device at the end of the bed, and the traction rope is passed through the pulleys, and the weight of the weight is used for traction. But because the weight of lower limb traction is generally 1/7～1/8 of the body weight, the weight is heavy, and the buckle often cannot carry the required weight of traction, and the traction adjustment is inconvenient.

Utility model content

The utility model is aimed at the fact that the existing electric hospital bed in the intensive care unit does not have the special traction function for orthopedics, and the existing lower limb fracture traction bracket function bed is expensive, and the existing self-made traction bracket has poor traction effectiveness and cannot adjust the traction angle according to the human body structure, etc. Insufficient, an adjustable electric bed lower limb fracture traction brace is proposed, which can be connected with the electric hospital bed in the intensive care unit, and the traction angle can be adjusted according to the human body structure, which can further improve the traction effect.

The technical scheme of the utility model is: an adjustable traction brace for lower limb fractures in an electric bed, including a bed body, a headboard set at the front end of the bed body, and a bed caster set at the bottom of the bed body; it is characterized in that: The traction support is composed of a traction insertion rod, a traction slider, a traction support slide bar, a traction support rod and a pulley; The traction sliders are spaced vertically and set at an angle of 145° to each other. The traction strut is provided with a through-groove through up and down, and the pulley is rotated in the through-groove through fasteners. The upper end is connected and fixed with the traction support slide bar, and the lower end of the traction insertion rod is plugged and connected with the connecting hole on the headboard.

Both the traction support slide bar and the traction support slide block are of hollow square steel pipe structure, and the traction support slide bar is sleeved on the traction support slide bar and forms a clearance fit with the traction support slide bar.

The length of the traction strut is 1.2 to 1.5 times the length of the traction slider.

The traction insertion rod is a cylindrical steel pipe structure, and the traction insertion rod forms a clearance fit with the connecting hole of the bedside frame.

The traction slider is welded and fixed to the traction strut.

The through groove is a rectangular groove, and the groove length of the through groove is 1.5 times of the diameter of the pulley.

The fastener is a combination of a bolt and a nut, and the middle part of the bolt is an optical axis structure.

The beneficial effects of the utility model are: the utility model proposes an adjustable electric bed lower limb fracture traction brace, which has a simple structure and a clear working principle. Compared with the traditional traction brace structure, the utility model traction brace can effectively To ensure the continuous effectiveness of traction, the traction angle can be adjusted according to the distance between the legs of the human body. The key is that it can be matched with the electric hospital bed in the intensive care unit. The manufacturing cost is low, the interchangeability is high, it is easy to promote and use, and the traction effect is further improved.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1-4, an adjustable electric bed lower limb fracture traction brace includes a bed body 1, a headboard 2 arranged at the front end of the bed body 1, and a bed caster 3 arranged at the bottom of the bed body 1; The traction support is composed of a traction insertion rod 4, a traction slider 8, a traction support slide bar 6, a traction support rod 5 and a pulley 7; The space of slider 8 is vertical and arranged at an angle of 145° to each other. The traction strut 5 is provided with a through groove through which the upper and lower sides penetrate. The pulley is arranged in the through groove through the rotation of fastener 9. The rod 6 is connected and fixed, and the lower end of the traction insertion rod 4 is plugged and connected with the connecting hole on the bedside frame 2 .

As shown in Figure 1-4, an adjustable traction brace for lower extremity fractures on an electric bed, the traction support slide bar 6 and the traction slide block 8 are both hollow square steel pipe structures, and the traction slide block 8 is sleeved on the traction support slide bar 6 and form a clearance fit with the traction support slide rod 6; the length of the traction support rod 5 is 1.2 to 1.5 times the length of the traction slider 8; The hole forms a clearance fit; the traction slider 8 and the traction strut 5 are welded and fixed; the through groove is a rectangular groove, and the groove length of the through groove is 1.5 times the diameter of the pulley; the fastener 9 is a combination of a bolt and a nut, and the middle part of the bolt is smooth. shaft structure.

As shown in Figure 1-4, the operation steps of an adjustable traction brace for lower limb fractures on an electric bed are as follows: remove the footboard of the electric bed, insert the designed traction rod 4 into the jack of the footboard, and adjust the height of the electric bed Make the traction rope parallel to the pulley, adjust the traction slide block 8 according to the fat and thin of the patient, and realize the regulation of the distance between the legs. The surgeon directly penetrates the traction needle into the body under local infiltration anesthesia of the affected limb, installs the traction bow, and fastens the rope to the traction bow. The gravity of the hammer resets the broken end of the fracture, avoids the displacement of the broken end and damages the surrounding blood vessels and nerves, and prevents and corrects deformities. Reduce damage.
