In the orthopedic treatment such as fracture, dislocation or sprain, a fixing bandage used for fixing and protecting the affected part of the patient is referred to as a cast or a Gips.

Plaster has been traditionally used as a casting material, and synthetic resins such as plastics have recently been used.

The procedure is generally performed by wrapping a bandage around the affected part of the patient, applying gypsum, or wrapping a plastic plate. In this conventional method, a stronger pressure than necessary may be applied to the affected part of the patient, There is a problem that proper fixation can not be performed due to a procedure that is less than pressure.

Strong pressure more than necessary causes blood circulation disorder or damage of the nervous system to the patient, and weak pressure which is less than necessary causes problems such as loose casting and continuous friction of the skin, causing skin damage or bone misjoining.

In addition, the period required to treat fractures is usually three to five weeks or more, and as a result, the affected part of the patient who has been pressurized by casting is not washed for a long time and is exposed to the risk of various skin diseases caused by bacterial propagation This causes the patient to suffer from severe itching, and is accompanied by a cast that is contaminated by sweat and various foreign substances, to a bad odor, which is uncomfortable not only for the patient but also for the surrounding people.

In the following description, well-known functions or constructions are not described in detail to avoid unnecessarily obscuring the subject matter of the present invention. Unless defined otherwise, all terms used herein are the same as the general meaning of the term understood by those of ordinary skill in the art to which this invention belongs and, if conflict with the meaning of the terms used herein, And the definition used in the specification.

In the description of the present invention, the name of the used component is defined by dividing the 'hole' and the 'groove', and the 'hole' is a hole penetrated from one side to the opposite side, But not to the other side.

In order to unify the description, the contents shown in the figure are based on the left hand, and the side where the hand is located is referred to as the upper side, the side where the palm is located is referred to as the lower side, The side where the base is located is defined as the left side, and the side where the thumb is positioned is defined as the right side.

FIG. 2 is a perspective view of a patient-customized wrist cast 1 according to an embodiment of the present invention. Referring to FIG. 2, the patient-customized wrist cast 1 of the present invention comprises a body 10, ).

The body portion 10 has an inner surface of an outline contour complementary to the surface contour of the patient's treatment area and is divided into two or more sections. Preferably, the body part 10 photographs the affected part of the patient's wrist by three-dimensional scanning and analyzes the profile of the wrist part of the patient so as to obtain an optimal cutting line L And the body part 10 of the cast 1 is manufactured through 3D printing. The inner surface of the body 10 should have a shape complementary to the surface contour of the patient's treatment area so that the body 10 can be brought into close contact with the affected part of the patient.

The outer surface of the body 10 may be configured to have various shapes. However, it is also possible to minimize the inconvenience during use by reducing the weight of the cast 1 and to provide a constant thickness The outer surface of the body 10 may be configured to have a shape complementary to the surface contour of the patient's treatment area.

The body portion 10 is manufactured through a series of processes described above. A hole for receiving a finger is formed on a front side of the casting 1, and a hole for receiving a wrist is formed on a rear side of the casting body 1 do. 2, the finger, the finger, and the finger are exposed to the outside of the body portion 10 through the same finger receiving hole, and the thumb is moved to the outside of the body portion 10 through the separate finger- But it is not necessary that the body portion 10 is formed in such a shape and it is possible to expose the thumb or the underside to the outside of the body portion 10 through the same finger receiving hole, I will include it.

However, according to the anatomical structure of the human body, the finger is composed of the distal, medial, and proximal phalanxes in the finger, It is made up of the proximal phalanx and is designed to point in a direction different from the direction indicated by the index finger, the finger, and the finger in the natural hand state. The patient's situation in which the hand can not move freely for a few weeks, The present invention is not limited to the above-described embodiment, but may be modified in various ways depending on the purpose of the cast 1, which must be in intimate contact with the affected part of the patient's wrist. It may be preferable to form a receiving hole for receiving the light.

Since the body 10 has an inner surface of the contour complementary to the surface contour of the treatment area of the patient, it does not generate a sufficient surplus space, so that a hand having a width larger than that of the wrist does not pass through the hole The body portion 10 is required to be divided into two or more sections through the cutting line L. In this case,

Fig. 3 shows an exploded perspective view of the wrist cast of Fig. 2 being divided along the cutting line; Fig. 3, the position of the cutting line L, which cuts the body 10, is determined when the affected part of the wrist of the patient is photographed through 3D scanning and the 3D shape data is obtained. It can be understood that the body part 10 is divided into two sections by the first body 11 on the upper side and the second body 13 on the lower side. However, the present invention is not limited to this cutting method, and the position of the cutting line L may be changed or increased by various factors such as the wrist shape of the patient and the position of the affected part.

When the body 10 is manufactured through the 3D printing technique or the like, the first body 11 and the second body 13 separated from each other by the cutting line L may be separately manufactured, A method may be used in which the entire body portion 10 is manufactured and then cut along the cutting line L determined later.

3, the body 10 is divided into the first body 11 and the second body 13. However, the number of the cutting lines L may be different in the production planning stage of the cast 1, The number of the body portions 10 divided into the body 11, the second body 13, the third body 15, and the like can be increased.

The body portion 10 includes a guide portion 111, a positioning portion 113, and a through hole 115. As described above, the body 10 can be divided into various shapes and numbers. Each of the divided bodies (the first body 11, the second body 13, etc.) The positioning portion 113 and the through hole 115 may be included in the body portion 10 in order to prevent the overlapping description. (115) will be described.

The guide part 111 is formed along the outer circumference of the body part 10 where a binding means 30 to be described later is to be positioned and the body part 10 is fastened So as to prevent a problem such as sliding off the surface of the body portion 10 and deviating its position in the process of applying strong pressure. The guide portion 111 may be divided into a first guide portion, a second guide portion, a third guide portion, and the like. And includes a protrusion guide portion 1111 and a recessed guide portion 1113.

The protrusion guide portion 1111 has a cavity 1111a protruding from the outer surface of the body portion 10 and having a shape corresponding to the binding means 30 on the inner side. And Fig. 5.

Fig. 4 is a view of the guide portion of Fig. 2, and Fig. 5 is a view of the projecting guide portion of Fig. According to the drawings, a plurality of protruding guide portions 1111 are formed along the outer circumference of the front end of the body portion 10. The protruding guide portion 1111 forms a cavity 1111a inside the cavity 1111a so as to guide the coupling means 30 tightly to the space into which the coupling means 30 It is preferable to have a shape corresponding to the shape of the base 30. For example, if the cross-section of the binding means 30 is rectangular, the shape of the cavity 1111a may also be a rectangle, and the size of the cavity 1111a may be the same as the cross-sectional peripheral size of the binding means 30. As a result, the binding means 30 is tightly guided by the projecting guide portion 1111 so that its position can be fixed on the outer surface of the body portion 10. [

According to the contents shown in FIG. 5, the bending direction at the position where the protrusion guide portion 1111 is located has a generally convex shape, but a point A on the curve indicating the position where the bending direction changes is referred to as an inflection point. It can be confirmed that the direction of bending of the outer surface of the body 10 where the binding means 50 is to be positioned is not constant. When the outer surface of the body portion 10 on which the coupling means 30 is to be positioned is not constant in the bending direction, it is preferable that the protrusion guide portion 1111 is formed.

The reason for this will be described with reference to FIG. 6, and FIG. 6 is a view showing a comparison of whether or not the binding means of the binding means changes depending on the position of the projection guide portion.

6 (a) is a plan view of the front side of the body 10, and FIG. 6 (b) is a plan view of the front side of the body 10, showing the engagement of the binding means 30 when the projecting guide portion 1111 is not formed at point A in the concave shape 6 (b) is a plan view of the front side of the body 10 as viewed from the front, showing the engagement of the binding means 30 when the projecting guide portion 1111 is formed at the point A of concave shape will be.

6 (a), when the body 10 is strongly tightened by the binding means 30, the body 10 can not be pressed down to the point A in the concave shape of the body 10, There arises a problem that the body 10 can not receive a balanced binding force from the binding means 30 because the binding means 30 is made to be spaced apart.

6 (b), the projecting guide portion 1111 is formed at the point A of the concave shape, so that the portion where the coupling means 30 is spaced apart from the outer surface of the body portion 10 is not made, It can be seen that the uniform binding force is transmitted to the body portion 10 through the binding means 30 and the body portion 10 is pressed and fixed.
