More specifically, the hip joint consists of a mandibular acetabulum and a ball-shaped femoral head that allows the free movement of the hamate and femur. When degenerative arthritis, rheumatoid arthritis, and arthritis due to trauma occur in these hips, the cartilage is broken and the hard bones come into direct contact with each other, resulting in severe pain and difficulty in walking. In this case, it is common to remove the part of the hip joint and treat it by inserting an artificial joint or a living implant.

The

communication modules

The processor 212 of the sensor 210 transmits detection information sensed by the sensing unit 214 to the user terminal 100 through the communication module 213 according to the program code stored in the recording device such as the memory 211. [ .

Meanwhile, the sensor 210 may include a sensing unit 214 for sensing attitude information of an object (e.g., the handle 200) to which the sensor 210 is attached in a three-dimensional space. The sensing unit 214 includes a gravity sensing unit for measuring gravity, a velocity sensing unit for sensing velocity, an acceleration sensing unit for sensing acceleration, an angular velocity sensing unit for sensing angular velocity, a geomagnetism sensing unit for sensing geomagnetism And an altitude sensing unit for sensing an altitude.

Meanwhile, the sensor 210 may provide the attitude information of the object to the user terminal 100 at predetermined time intervals (for example, 0.1 second). In other words, the sensor 210 can provide attitude information of the object to the user terminal 100 in real time. The user terminal 100 can confirm and guide the current insertion angle of the structure 500 based on the attitude information of the object provided from the sensor 210 in real time. Details thereof will be described later.

For example, the user terminal 100 may be implemented to include at least some of the input / output devices 115 described above, or may include other components such as a transceiver, a Global Positioning System (GPS) module, a camera, As shown in FIG.

Also, in another embodiment of the present invention, the sensor 210 and the user terminal 100 may be integrally configured. In other words, the user terminal 100 according to another embodiment of the present invention may include the sensor 210. [ At this time, the user terminal 100 may be attached to the handle 200 in the same manner as the above-described sensor 210 to check and guide the current insertion angle of the structure 500.

Hereinafter, the operation of the processor 112 of the user terminal 100 for guiding the insertion angle of the structure will be mainly described.

The processor 112 in accordance with an embodiment of the present invention may obtain movement range data of the first bone for the second bone.

In the present invention, 'movable range of bones' means a range in which the corresponding bones can be operated in a three-dimensional space. For example, in a three-dimensional space, the bones may be movable in a plurality of directions . The range of motion of such bones can be defined as the maximum positive range of motion and the maximum negative range of motion for each direction. Detailed explanations related to this will be described later.

On the other hand, the movement range data of the first bone can be obtained by various methods. For example, the operating range data may be obtained by a user's input to the user terminal 100. In other words, the operating range data can be obtained by the doctor measuring the range of motion of the first bone with respect to the second bone of the patient, and inputting the measurement result to the user terminal 100. [

The movement range data may also be obtained by a sensor (not shown) attached to the patient's body. In this case, the sensor (not shown) may be a sensor having the same structure and role as the sensor 210 attached to the handle 200. In other words, the sensor (not shown) can sense the posture on the three-dimensional space of the body part to which the sensor (not shown) is attached and provide the sensed posture information to the user terminal 100. The user terminal 100 can acquire the movable range data by accumulating attitude information received from a sensor (not shown). More specifically, the physician can acquire the moving range data by operating the first bone with the first bone combined with the second bone (the second bone fixed by fixing the body to the bed) fixed at a predetermined position . That is, the movement range data can be obtained by activating the remaining bones (i.e., body parts) to which the sensor is attached in a state in which the bones of one of the two bones constituting the joint to which the movable range is to be determined is fixed.

Such acquisition of the moving range data may be preferably obtained before the structure 500 of FIG. 1 is inserted into the second bone 300 of FIG. In other words, the movement range data may be obtained in a state where the second bone 300 of FIG. 1 and the first bone 400 of FIG. 1 are combined (for example, a state before starting surgery on the patient).

On the other hand, the movement range data acquired by the processor 112 may include an angular motion range of the first bone around at least one direction on the three-dimensional space.

Figs. 3A to 3C are views for explaining respective movable ranges of the first bone in the three-dimensional space. Fig. For convenience of explanation, the insertion angle guiding system of the structure according to the embodiment of the present invention is configured such that the insertion angle of the artificial acetabular cup for coupling with the femur (first bone) to the medullary bone (second bone) As shown in FIG.

The movable range data under the above-mentioned premise may include the respective movable ranges of the first bones about the first direction, the second direction and the third direction orthogonal to each other as shown in Figs. 3A to 3C.

First, referring to FIG. 3A, the movement range data may include respective

movable ranges

610 and 620 of the femur (first bone) relative to the amniotic bone (second bone) having the + X direction as the rotation axis. At this time, each of the

movable ranges

610 and 620 has a positive angular range 610 based on a predetermined reference angle (for example, an angle at which the first bone becomes parallel to the vertebral bone) And a negative angular range 620 with respect to the reference angle.

Also, referring to FIG. 3B, the movable range data may include the respective

movable ranges

630 and 640 of the femur (first bone) relative to the unshown bone (second bone) with the + Y direction as the rotational axis. At this time, each of the

movable ranges

630 and 640 may include a positive angular range 630 based on a predetermined reference angle and a negative angular range 640 based on a predetermined reference angle.

Lastly, referring to FIG. 3C, the movement range data may include respective

movable ranges

650 and 660 of the femur (first bone) for the non-musculoskeletal bone (second bone) with the + Z direction as the rotation axis. At this time, each of the

movable ranges

650 and 660 may include a positive angular range 650 based on a predetermined reference angle and a negative angular range 660 based on a predetermined reference angle.

In the present invention, 'angle' refers to a specific angle such as 30 degrees and 45 degrees, and 'each operating range' refers to a range of angles defined as a starting angle and an ending angle, such as 0 degrees to 40 degrees, . &Lt; / RTI >

The processor 112 according to an embodiment of the present invention can calculate the effective insertion angle range of the structure based on the movable range data obtained by the above-described process. For example, the processor 112 may calculate an angle within a predetermined angle range from a central angle of each movable range of the first bone obtained by the above-described process to an angle belonging to the effective insertion angle range. In this case, the 'effective insertion angle range' may refer to an interval of an angle defined by a start angle and an end angle, similar to the 'each movement range' described above. The 'center angle' may also mean the angle of the point at which the angle between the start angle and the end angle of each operating range is divided by half. For example, if the operating range is from -30 to +60 degrees, the central angle may be +15 degrees. At this time, the processor 112 may calculate an angle belonging to an angle within a range of +15 degrees to +5 degrees from a center angle of +15 degrees, that is, an angle between +10 degrees and +20 degrees. However, this is an example.

On the other hand, the predetermined angle range can be determined according to the precision required by the operation. If high precision is required, for example, the predetermined angle may be determined to be 0.5 degrees, 0.1 degrees, or zero degrees. On the other hand, when relatively low precision is required, the predetermined angle may be determined to be 5 degrees, 7 degrees, or the like.

When the predetermined angle is 0 degree, the central angle itself may be an effective insertion angle range. In other words, if the predetermined angle is 0 degrees, the structure may be inserted at an angle coinciding with the center angle.

If, on the other hand, the motion range data includes the first bone angular motion range that is each of a plurality of directions on the three-dimensional space, processor 112 according to one embodiment of the present invention may include a plurality The effective insertion angle range for each of the movable ranges of the plurality of first bones about the axis of the first bone can be calculated.

Assume that the movable range data includes the respective movable ranges of the first bones having the + X direction, the + Y direction and the + Z direction, which are orthogonal to each other as shown in Figs. 3A to 3C.

In this case, the processor calculates the central angle of each

movable range

610, 620 of the first bone with the + X direction as the rotation axis, and calculates an angle within a predetermined angle range from the calculated central angle with an angle belonging to the effective insertion angle range Can be calculated. The effective insertion angle range calculated at this time may be meaningful as the effective insertion angle when the + X direction is the rotation axis. Meanwhile, the processor can calculate the effective insertion angle range when the + Y direction is the rotation axis and the effective insertion angle range when the + Z direction is the rotation axis by a similar method.

Thus, the insertion guide device of the structure according to the embodiment of the present invention can calculate the effective insertion angle range of the structure in the three-dimensional space.

4 is a view showing a valid insertion angle range 680 calculated by the processor 112 on a three-dimensional space according to an embodiment of the present invention.

Referring to FIG. 4, it is assumed that each movable range 670 of the first bone on the three-dimensional space is as shown. Each of the movable ranges 670 may be obtained by moving the first bone (femur, not shown) attached with the sensor while the second bone (innocent bone) 300 is fixed as described above.

Meanwhile, the processor 112 may calculate an angle that falls within a predetermined angular range from the central angle 690 of each movable range 670 of the first bone to an angle belonging to the effective insertion angle range 680, as described above. At this time, the center angle 690 may be determined by considering all of the central angles when the plurality of directions are the movable axes.

The processor 112 according to an embodiment of the present invention can then compare the current insertion angle of the structure with the effective insertion angle range calculated by the above process. At this time, the current insertion angle of the structure may be received from the sensor 210 attached to the handle 200 as described above. The handle 200, on the other hand, may be used by a user such as a physician. For example, the physician may use the handle 200 with the sensor 210 attached thereto for insertion of the structure.

The handle 200 may also be attached to a robot for structure insertion surgery. For example, the robot can receive information about the current insertion angle from the sensor 210 attached to the handle 200 and control the robot arm or the like to which the handle 200 is attached so that the structure can be inserted at a more correct angle.

5 is a view for explaining a method of guiding insertion of a structure 500 according to an insertion angle guiding system of a structure according to an embodiment of the present invention. For convenience of explanation, it is assumed that the central angle 690 and the effective insertion angle range 680 are calculated by the processor 112 by the processes described with reference to FIGS.

Under the above assumptions, the processor 112 according to one embodiment of the present invention may compare the current insertion angle of the structure 500 with the effective insertion angle range 680. [ The processor 112 may also provide a comparison of the current insertion angle and the effective insertion angle range 680. At this time, the processor 112 may visually provide the extent to which the current insertion angle deviates from the effective insertion angle range, as shown in FIG. The processor 112 may also provide the degree to which the current insertion angle deviates from the effective insertion angle range in the form of sound.

The user can appropriately adjust the insertion angle of the handle 200 based on the provided information so that the structure 500 can be inserted into the second bone 300 in the correct direction.

6 is a flowchart illustrating a method of guiding an insertion angle of a structure performed by a user terminal 100 used as an insertion angle guiding device of a structure according to an embodiment of the present invention. Hereinafter, the description of the contents overlapping with those described with reference to FIGS. 1 to 5 will be omitted.

The user terminal 100 according to an embodiment of the present invention may acquire the moving range data of the first bone with respect to the second bone. (S61) At this time, the movement range data of the first bone can be obtained by various methods. For example, the operating range data may be obtained by a user's input to the user terminal 100. In other words, the operating range data can be obtained by the doctor measuring the range of motion of the first bone with respect to the second bone of the patient, and inputting the measurement result to the user terminal 100. [

The movement range data may also be obtained by a sensor (not shown) attached to the patient's body. In this case, the sensor (not shown) may be a sensor having the same structure and role as the sensor 210 attached to the handle 200. In other words, the sensor (not shown) senses the posture of the body part to which the sensor is attached in the three-dimensional space, and provides the sensed posture information to the user terminal 100. The user terminal 100 can acquire the movable range data by accumulating attitude information received from a sensor (not shown).

More specifically, the physician can acquire the moving range data by operating the first bone with the first bone combined with the second bone (the second bone fixed by fixing the body to the bed) fixed at a predetermined position . That is, the movement range data can be obtained by activating the remaining bones (i.e., body parts) to which the sensor is attached in a state in which the bones of one of the two bones constituting the joint to which the movable range is to be determined is fixed.

On the other hand, the movement range data acquired by the user terminal 100 may include an angle movement range of the first bone around at least one direction on the three-dimensional space.

Referring again to FIG. 3A, the movement range data may include the respective

movable ranges

610 and 620 of the femur (first bone) relative to the amygdala (second bone) with the + X direction as the rotation axis. At this time, each of the

movable ranges

Also, referring to FIG. 3B, the movable range data may include the respective

movable ranges

Lastly, referring to FIG. 3C, the movement range data may include respective

movable ranges

The user terminal 100 according to an embodiment of the present invention can calculate the effective insertion angle range of the structure based on the movable range data obtained by the above-described procedure. (S62). For example, the user terminal 100 may calculate an angle that falls within a predetermined angle range from the central angle of each movable range of the first bone obtained by the above-described process, as an angle belonging to the effective insertion angle range. In this case, the 'effective insertion angle range' may refer to an interval of an angle defined by a start angle and an end angle, similar to the 'each movement range' described above. The 'center angle' may also mean the angle of the point at which the angle between the start angle and the end angle of each operating range is divided by half. For example, if the operating range is from -30 to +60 degrees, the central angle may be +15 degrees. At this time, the user terminal 100 can calculate an angle belonging to an angle between +10 degrees and +20 degrees within an angle of 5 degrees or less from a center angle of +15 degrees, to an angle belonging to an effective insertion angle range.

On the other hand, if the movement range data includes the first bone angular motion range, each of which is an axis of each of the plurality of directions on the three-dimensional space, the user terminal 100 according to one embodiment of the present invention, It is possible to calculate the effective insertion angle range for each movable range of the plurality of first bones having the respective axes as the axis.

In this case, the processor calculates the central angle of each

movable range
