In general, the minimally invasive fracture reduction surgery is a fracture reduction surgery that minimizes the incision of a patient, and in such a fracture reduction surgery, real-time X-ray imaging equipment such as C-ARM is used to correct the displaced bones in place. And fix the bone fragments corrected by inserting a metal tablet in the bone marrow in the corrected state.

In the process of bone fracture surgery, it is difficult to visually check the fracture condition of the bone, the conquest process, and the occlusal state according to the conquest, as the fracture part of the bone is located deep inside the skin. The fracture part of the patient is positioned between and the 2D sensor to acquire an X-ray image in real time, and the operator proceeds with the fracture reduction operation while checking the real-time X-ray image.

However, since X-ray imaging equipment such as C-ARM requires continuous irradiation of X-rays to obtain real-time images, the radiation exposure to the operator and the operator and the medical staff is significantly higher than other X-ray equipments that obtain still images. There is this.

In addition, since various muscles are connected to the bone, great power is required for the conquest of the fractured bone, and as a number of medical staff cooperate with each other to perform the surgery, a large number of medical staff are needed to proceed with the fracture repair surgery. This was a factor in raising the cost of surgery.

In addition, after correction of the displaced bone is performed by a medical staff, it is difficult to effectively maintain a corrected state in which the corrected state is fixed by a method such as inserting a metal tablet into the bone marrow cavity, and for this reason, fracture repair is incorrectly performed. There was a problem that the possibility of becoming always exists.

The first driving means 510,

It is a means for varying the length of the above-described strut module 400, and may be configured to include a drive motor 511 and a reducer 512.

The first driving means 510 is connected to the strut module 400 connected to the first frame 100 through the first clamp 412 as shown in FIGS. 5 and 6, and specifically, the first driving means ( The reduction gear 512 connected to the driving motor 511 of 510 is connected to the first joint 411 connected to the lead screw top of the strut module 400, so that the rotational force of the driving motor 511 is the reduction gear 512 When the lead screw 410 is rotated by the operation of the driving motor 511 as it is transmitted to the lead screw 410 through the 1st joint 411 and the lead screw 410, the lead screw 410 enters and exits from the sleeve 420. The total length of 400 can be adjusted.

Here, the first driving means 510 and the strut module 400 may be configured in a combination form such as a keyway and a key to transmit the rotational force, but the magnet coupling 530 is a preferred embodiment as shown in FIGS. 5 and 6. It can also be connected to each other.

That is, the first magnet 531 is installed on the top of the first joint 411 connected to the lead screw 410 of the strut module 400, where the first magnet 531 is attached to the first frame 100. It is seated and fixed to the installed first clamp 412.

It is a means for rotating the above-described first frame 100 under the guidance of the third frame 300, and may include a driving motor 521 and a reduction gear 522.

As illustrated in FIGS. 2 and 3, the second driving means is wrapped by the case 524 together with the servo drive 523 and is configured by the second driving module 500b, and the first through the fixing bracket 540. It may be fixed to the frame 100.

In addition, a gear plate 310 having a fixed gear 311 is installed on a portion of the bottom surface of the third frame 300, and the fixed gear 311 of the gear plate 310 is installed on the second driving module 500b. The movable gear 525 is installed to be meshed with the first driving while being engaged with the fixed gear 311 of the gear plate 310 when the movable gear 525 is rotated according to the operation of the second driving module 500b. The first frame 100 connected to the module 500a rotates, and accordingly, the driving range of the strut module 400 connected to the first frame 100 through the first clamp 412 is further extended. It is possible.

The case 524 of the second driving module 500b is also formed with a space portion having a predetermined size therein, and the upper cap 526 coupled to maintain the airtightness on the upper and lower parts of the body 528 and the body 528. It may be composed of a lower cap 527 coupled to maintain airtightness at the bottom of the body 528, and the upper cap 526 is provided with terminals (not shown) for transmitting and receiving power and data, and the lower cap. On the surface of the 527, a hole (not shown in the drawing) penetrating the inside and outside is formed, and after the movable gear 525 is installed in the reduction gear 522 connected to the driving motor 521 which is the second driving means 520, such The movable gear 525 may be directly engaged to the fixed gear 311 of the gear plate 310 through a hole (not indicated in the drawing), but for convenience of design, the auxiliary gear 526 is fitted to the movable gear 525 , A part of the auxiliary gear 526 through the hole fixed gear (3) of the gear plate 310 It is preferably configured to mesh with 11).

Accordingly, when the driving motor 521 of the second driving means 520 is driven, its rotational force rotates the movable gear 525 through the reduction gear 522, and the auxiliary gear 526 engaged with the movable gear 525 The first frame 100 is rotated together with the second driving module 500b while being sequentially engaged with the fixed gear 311 formed on the gear plate 310 of the third frame 300, and the first frame 100 ) Through the sliding means 320 installed on the bottom surface of the third frame 300 can be rotated smoothly and without friction resistance.

In the present invention, the offset member 600 is installed between the sleeve 420 of the strut module 400 and the second joint 421 to expand the driving range using the basic variable length of the strut module 400. If the expansion of the driving range is required while performing the conquest through, the adjustment member 620 and 620a are pulled out from the housing 610 and 610a of the offset member 600 to offset the variable length of the strut module 400 By adding a variable length of (600), it is possible to increase the precision and efficiency of conquest through additional expansion of the driving range, and at the same time, through the rotation of the first frame (100) by the operation of the second driving module (500b) By further extending the driving range according to the relative position and posture of the first frame 100 and the second frame 200, it is possible to further increase the precision and efficiency of conquest.
