Description

Device to prevent radiation exposure during surgery using C-arm}

The present invention relates to an apparatus for preventing radiation exposure during surgery using C cancer, and more particularly, to an apparatus for preventing radiation exposure of medical personnel in an operating room during surgery using C cancer.

For example, in a surgery using CT scan, the operation is performed simultaneously while looking at the C-arm findings during the operation, and the risk of exposure of medical personnel in the operating room due to the radiation emitted from the C-arm used during the surgery. This is always pointed out. In order to reduce such risks, medical personnel are making efforts to block exposure to radiation by carrying out surgery with a shielding suit or shielding glasses. However, such equipment is very inconvenient after wearing, and its weight causes considerable strain on the spine. In addition, even when wearing the exposure shielding equipment there is a limit that can not effectively prevent all the x-rays reflected from the C-arm radiated from all directions or hit other places.

Is a view illustrating an apparatus for preventing radiation exposure during surgery using C cancer according to an embodiment of the present invention.

1 to 4, the radiation exposure prevention device 100 during the operation using the C-arm according to an embodiment of the present invention includes a surgical table 110, a cradle 120, a radiation shielding film 130, The U-shaped portion 121 may further include a bolt 150 having a handle.

The operating table 110 is a bed in which the patient lies down during surgery.

Referring to Figure 1, the guide bar 140 is installed on the side of the operating table (110). The guide bar 140 is installed to be disposed in the longitudinal direction or the width direction at the side of the operating table (110). The guide bar 140 guides the movement of the holder 120 to be described later.

The cradle 120 may be a P-shaped frame. Both ends of the П-shaped holder 120 may be coupled to both ends of the operating table 110, more specifically, guide bars 140 installed on both ends of the operating table 110.

At this time, both ends of the holder 120 has a U-shaped portion 121, the center region of the U-shaped groove as shown in Figure 2 so as to be connected to the corresponding guide bar 140. Accordingly, the U-shaped portions 121 at both ends of the cradle 120 may be moved in the longitudinal direction or the width direction of the operating table 110 in a state of being fitted to the guide bar 140.

In this case, the bolt 150 having a handle serves to fix the U-shaped portion 121 of the holder 120 to the guide bar 140 as shown in FIGS. 1 and 2. Accordingly, the holder 120 may slide along the guide bar 140, but may be fixed to the guide bar 140 as necessary.

In addition, the holder 120 serves to stably position the radiation shielding film 130 on the operating table (110) so as not to interfere with the C arm (10) approaching the operating table (110).

To this end, the cradle 120 is composed of a plurality as shown in Figure 1, spaced apart from each other at the operating table (110). Accordingly, the plurality of holders 120 can slide along the guide bar 140 on the operating table 110 (in the longitudinal direction or the width direction according to the installation of the guide bar 140). Therefore, there is an advantage that the distance between the cradle 120 and the cradle 120 adjacent to each other can be adjusted as necessary.

The radiation shielding film 130 is made of a material such as cloth or urethane containing a shielding material capable of shielding radiation. The radiation shielding film 130 may be in the form of a rectangular or forward curtain, and may be fixed on the operating table 110 through the above-described cradle 120 as shown in FIGS. 3 to 4. At this time, the radiation shielding film 130 can be completely wrapped in the upper portion and the side of the patient by being mounted in the letter-shaped (120). For reference, in spinal surgery, the patient is lying on his back and lying on the operating table 110, the radiation shield 130 is in the form to cover the back and sides of the patient.

Referring to FIG. 3, in a situation in which an anteroposterior view or an AP view, that is, a generator of the C arm 10 is positioned below the operating table 110, is directed to the right side and the front and rear surfaces of the operating table 110. The sagging radiation shielding film 130 may shield both the direct wave coming out from the operating table 110 and the indirect wave reflected from the operating table 110 and the floor. Accordingly, the medical personnel located on the right side of the operating table 110 based on FIG. 3 may be protected from radiation exposure through the radiation shielding film 130.

Referring to FIG. 4, a right lateral view or a RL view or a left lateral view or an LL view, that is, a generator of the C-arm 10, is raised toward the medical person and the patient and the medical person. In the situation in which the medical personnel are directly adjacent to the generator, the patient is exposed to a large amount of x-rays, wherein the radiation shielding film 130 attached to the holder 120 is in all directions except the straight direction and the downward direction of the generator. By enclosing, the medical personnel can be protected from direct and indirect exposures. At this time, since the radiation shielding film 130 does not interfere with x-rays in the straight direction of the generator, the lateral imaging is not disturbed.

In addition, the radiation shielding film 130 of the present embodiment is a structure that can be separated from the holder 120 after surgery. Thus, the radiation shielding film 130 can be cleaned cleanly and thus can be processed and reused in a completely sterile state. That is, since the structure can be separated from time to time by using a sterile radiation shielding membrane 130 after washing it can be prevented accidental contamination during surgery.

5 is a view showing a means for fixing the radiation shielding film to the cradle according to an embodiment of the present invention.

Referring to FIG. 5, the radiation exposure preventing apparatus 100 of the present embodiment may further include a fixing part 160 fixing the radiation shielding film 130 to the holder 120.

The fixing part 160 may be formed of, for example, a string provided on the top of the radiation shielding film 130. Therefore, the position of the radiation shielding membrane 130 may be adjusted or detached to the holder 120 by loosening or tying a string as needed before or after surgery.

Although the drawings describe a case in which the fixing part 160 is formed of a string, the present invention is not necessarily limited thereto. For example, the fixing part 160 includes a magnet fixed to the top of the radiation shielding film 130 and the holder 120. ) May be in the form of being bonded by being made of iron.

In addition, the fixing unit 160 may include a plurality of tongs fixed in a row on the holder 120, and the radiation shielding film 130 may be coupled by being gripped by these tongs.
