Description

Method and device for taking pelvic hip joint prosthetic plaster cast

The present invention relates to a method for taking pelvic and hip joint prosthetic plaster and its taking device. It uses an auxiliary taking device to make a patient sit upright and straddle it, and can be quickly operated and accurately taken by adjusting components on the device. Mould method and device.

The amputation of part of the body’s limbs for any reason is a painful decision of last resort. The reason is nothing more than congenital diabetes genes, bone cancer or trauma caused by accidents, and leg amputations are usually divided into legs. Lower of knee BK (Below of knee BK), Above of knee AK (Above of knee AK), and hip amputation with the hip joint above the thigh removed.

For any patient with amputation caused by the above reasons, if he decides to assemble an artificial prosthesis, the patient’s residual limb must be wetted with a plaster bandage during the production of the prosthetic limb to take a mold in order to make a plastic bearing. The tube allows components such as artificial limbs, joints and soles to be extended downward from the bearing tube to be assembled.

As we know, human calf amputation and thigh amputation still have long and short stumps. Therefore, it is not too difficult to make the model of the bearing tube, but even the hip joint connecting the pelvis and thigh has been amputated. Except for the patient’s pelvic and hip joint model, it is a more difficult and precise model taking procedure. The main reason is that the patient lacks a whole thigh or even the pelvis is incomplete. It is implemented in cooperation with the prosthetist. , There are indeed difficulties.

The traditional method of taking the plaster cast of the pelvic hip joint bearing tube is that one of the authors first wraps a plaster bandage on the patient’s residual limb, then uses two triangular wooden wedges to clamp the front and back sides of the residual limb and make the patient sit in a sitting position. In the posture, another provider uses elastic belts to clamp the iliac crests on both sides of the hip bones for positioning and shaping. The hands are used to maintain the balance and compression support of the body, pelvis and existing legs, and wait for the plaster to harden. Then take out the mold.

In other words, it requires several people to push, squeeze, squeeze or drag in an extremely unstable state of panic, and under the psychological burden of the patient, especially when the patient is a female, the physical contact operation is more important. It is sensitive, and the mold-taking procedure is hurriedly completed. Obviously, the accuracy of the plaster mold is really worrying.

In view of the serious lack of traditional pelvic and hip joint prosthetic plaster casting methods, the research team of the Germination Center for Disability Center developed an engine, through research, innovation, experimentation and implementation, finally developed the "pelvic and hip joint prosthetic plaster casting method and its device" "Invention and creation.

The method and device for taking pelvic and hip joint prosthetic plaster cast molds of the present invention utilizes an auxiliary mold taking device, so that the patient can sit upright and straddle on it to quickly operate and take the mold on the device. The mold taking device is mainly connected to a An adjustment seat is fixed on one end of the main substrate, and a corresponding movable adjustment seat is arranged on the other end. The main substrate is provided with an arc adjustment seat that can adjust upper, lower, left and right curvatures in the vertical direction between the two adjustment seats.

The patient sits on a fixed adjustment seat in advance, and quickly moves the adjustment seat to the approximate position, adjusts the height and curved surface of the arc adjustment seat, and then spreads a proper amount of moisture on the inner edge of the two adjustment seats and the arc adjustment seat Plaster bandage, and make the patient sit upright and relax straddling on the fixed adjustment seat, and then rotate the screw to push the inclined pressure plate of the adjustment seat and the baffle of the arc adjustment seat, according to which the follow-up required gypsum can be obtained accurately appearance.

According to the present invention, the pelvic and hip joint prosthetic plaster mold taking device, depending on the individual situation, will be additionally provided with a soft pad on the device base plate to improve the comfort of the case when taking the mold. It can also be equipped with a fixed belt or an elastic fixing belt , So that it can improve the positioning effect, efficiency and accuracy of mold taking.

As shown in Figures 1 to 3, the pelvic and hip joint prosthetic plaster mold taking method and the mold taking device thereof according to the present invention, wherein the pelvic hip joint prosthetic plaster mold taking device is an auxiliary mold taking device, which mainly includes a main substrate ( 1), a quick positioning push rod (2), a fixed adjusting base (3), a movable adjusting base (4) and an arc adjusting base (5).
