Description

Fixed bed for hip replacement

technical field

The invention belongs to a surgical operating bed, in particular to a fixed bed used for hip joint replacement surgery.

Background technique

With the continuous improvement of my country's comprehensive national strength, patients with femoral head necrosis and femoral neck fractures are more inclined to choose total hip replacement. Currently, the posterolateral approach is mostly used for surgery, because of its advantages of relatively small trauma and sufficient field of view, it is highly recommended by the majority of surgeons. The operation requires the patient to lie on the healthy side, with a baffle in front to support the patient's pubic symphysis, and another baffle to support the patient's sacral coccygeal area in the rear, and the positional tape can be used to fix the patient in the lateral recumbent position on the healthy side. For patients with obvious shortening of the affected limb measured before operation, the affected limb needs to be lengthened, and a strong and stable traction resistance is required during the operation. Then, when placing the patient's position before the operation, it is necessary to add traction and fixation to the patient's perineum.

1. Disadvantages of existing methods:

For patients who need to extend the affected limb during the operation, when traction is added to the genitals, the problems often encountered are: 1. The traction is loose; 2. The traction force is not enough; 3. The perineum is crushed or easily crushed Penis and scrotum of a male patient. There are also unnecessary troubles during the operation and additional pain to the patient because the preoperative body position is not fixed firmly.

Contents of the invention

In order to solve the above technical problems, the purpose of the present invention is to provide a device that can not only fix the patient's front position firmly, but also provide strong and stable traction resistance.

The object of the present invention is achieved in the following way: a fixed bed for hip joint replacement, comprising a bed, the bed is covered with a mattress, the key lies in: a telescopic rotating rocker mechanism is arranged in the middle of both sides of the bed, and the telescopic rotating rocker The mechanism is composed of a fixed seat, a vertical rod, a horizontal telescopic rod, a circular tube and an "L"-shaped connecting rod. The two ends of the horizontal telescopic rod are vertically connected with the upper circular tube and the lower vertical rod respectively, and the upper end of the circular tube is set with "L" The outer wall of the round tube is radially fixed with a screw sleeve, and the nut cooperates with the screw sleeve and extends into the round tube to resist the "L" shaped connecting rod. The upper end of the vertical rod is connected with the horizontal telescopic rod and fixed by the nut , the lower end of the vertical rod passes through the fixed seat fixed on the side of the bed, and a screw sleeve is fixed on the outside of the fixed seat, and the nut cooperates with the screw sleeve and extends into the fixed seat to resist the vertical rod; the two telescopic rotating rocker mechanisms The outer ends of the "L"-shaped connecting rods are respectively fixedly connected with short baffles or long baffles; cloth belts are connected between the fixed vertical bars on both sides of the bed, and the ends of the cloth belts are connected between the horizontal telescopic rod and the fixed seat on the vertical bars between them. The length and rotation angle of the telescopic rotating rocker mechanism are adjusted, the short baffle is against the patient's pubic symphysis, and the long baffle is against the patient's sacrum. When the affected limb is extended, because the person is lying on his side, the cloth belt wraps around the root of the patient's thigh on the bed to provide stable traction resistance. It will not crush the perineum, or easily crush the penis and scrotum of male patients. To facilitate the normal operation, the end of the cloth belt is connected to the vertical rod between the horizontal telescopic rod and the fixing seat. The end of the cloth belt is bolted on or sleeved on the vertical rod. During the traction resistance, the horizontal telescopic rod and the fixing seat can limit the up and down of the cloth belt to ensure stable traction resistance.

Above-mentioned tape is made of elastic material. The traction resistance is more gentle, and the force is gradually increased when the root of the patient's thigh is encased, so that the patient's thigh will not be damaged.

The above-mentioned horizontal expansion rod is composed of a horizontal rod and a horizontal rod sleeve. A part of the horizontal rod extends into the horizontal rod sleeve. described transverse bar positioning. The horizontal telescopic rod can adjust the length of the horizontal telescopic rod by how much the horizontal rod stretches into the horizontal rod sleeve, and it will not move relative to each other by the nut against the horizontal rod. The adjustment range of the entire telescopic rotary rocker mechanism is further expanded.

The above-mentioned nut is divided into a head, a neck and a tail, wherein the head is a nearly quadrangular plastic pan head, and the tail is provided with external threads, and the diameter of the neck is greater than the diameter of the tail. It is less labor-saving to rotate the approximate quadrilateral directly by hand when tightening the nut, and the neck has no thread, so that there is a certain distance between the head pan head and the tightened object after tightening the nut. It is convenient to screw the nut and reach the plastic pan head to protect the head.

Beneficial effects: the present invention fixes the patient's front position firmly during the operation, which is beneficial to the operation. At the same time, for the patient who needs to extend the affected limb during the operation, when performing traction, the traction resistance can provide sufficient traction force and will not squeeze Crushing the perineum will not crush the penis and scrotum of male patients. No additional pain will be brought to the patient.
