Description

Surgical Retractor with Illumination Function {RETRACTOR FOR OPERATION HAVING LIGHTING FUNCTION}

The present invention relates to a surgical retractor having an illumination function. More specifically, a detachable lighting device is installed on the side or bottom surface of the retractor used to spread the rib cage to the left and right during thoracic surgery. Accordingly, the present invention relates to a surgical retractor having an illumination function that can sufficiently and securely operate the field of view and brightness of the opened surgical site, and can be easily removed after the operation.

Korean Patent Laid-Open Publication No. 10-2006-0011091 discloses a sternum retractor for heart surgery. As shown in Fig. 4, the sternum retractor disclosed in the above document is a length member and a support member 1 and a support member having a plurality of teeth 2 formed on one side thereof in a streamlined upward direction toward both ends and formed on one side thereof. The fixing member 3 fixedly installed at one end of the (1), the movable member 4 facing the fixing member 3 and movable to the other end of the supporting member 1, and the lower portion of the movable member 4 Rotating member (5) installed on the supporting member (1) and transmitting the movement force to the left / right along the plurality of teeth (2) formed in the supporting member (1) during rotation, and installed on the rotating member (5) Technical configuration is provided with a handle (6) to smoothly perform the rotation.

Conventional sternum retractor having the configuration as described above, to insert the fixing member and the moving member between the sternum to open the sternum and then rotate the handle. Then, the movable member engaged with the rotating member moves along the supporting member and is opened to secure a necessary field of vision during surgery. The retractor as described above may be opened by the fixing member and the moving member, but since the retractor is not provided with a separate light emitting device or a lighting device, the opened surgical part is narrow and dark, which makes operation difficult.

In order to solve the above problems, an assistant is added to illuminate the surgical site with the operator. However, the operator and the assistants are entangled in the cramped operating room, and the assistant needs to illuminate while changing the position from time to time in order to secure the vision required for the procedure. In addition, there is a problem that the operation is delayed due to frequent position changes.

In addition, in order to ensure sufficient visibility and brightness during surgery, the surgeon may operate by directly wearing a light emitting device or a lighting device on the head. However, this is not enough for narrow and deep surgical sites. In addition, since the operator needs to continuously access and illuminate the light emitting device mounted on his head in order to secure sufficient vision and brightness, the posture is difficult and difficult during long time operation, and smooth operation is difficult. There is another problem that can not be a safe operation due to a decline in physical strength and concentration during long hours in a difficult posture.

Thoracic surgery requires a great deal of care by cutting a person's body, cutting the rib cage vertically and opening it, and then cutting and suturing the inside of the human body. Among the existing diagnostic equipment or surgical equipment, a lot of equipments with lighting devices for securing the operator's field of view have been provided. However, most of these devices supply electricity directly to the lighting device by using electricity or a battery. If such lighting equipment is used as it is, the electric wire is exposed to the contact with the surgical knife during the operation, there is a risk of causing an electric shock accident to the patient. In addition, when using a battery, it may suddenly turn off in a long time operation, and there is a risk of causing a fatal mistake of dropping a small battery inside the body while replacing the battery. Thus, in fields such as thoracic surgery, there is an essential task of supplying illumination in a manner that does not have electrical conductivity.

In addition, the reusable one of the surgical instruments once used performs a thorough disinfection process. However, tools with many bends, many assembled gaps, and are not easy to disassemble and reassemble are desirable to be discarded after one use. Thus, once the lighting device used in a patient's body for a long time in the operation is removed from the retractor and the retractor is disinfected and reused, there is a further problem that the lighting device must be disposed of. In other words, it should be possible to detach and attach. In addition, since it is disposed of for one-time disposal, it is desirable to configure at a low price as possible, to minimize the cost required for surgery.

It includes a power jack 129 for. In this case, the optical connector 126 is used to connect the first and second optical fibers 123 and 124 and the first and second light sources 127 and 128 corresponding thereto.

The optical connector 126 is physically connected to the optical fiber and the light source using a thermoplastic coating, and is also optically connected to transmit light from the light source to the optical fiber. Therefore, a photo coupler or a photo connector is basically used, but the present invention is not limited thereto, and may further include a fastening bolt, a clip, a band, a pinch member, and the like. In addition, it is preferable to use the optical connector 126 that is harmful to the human body and is not deformed by an electromagnetic wave or a light source. Moreover, it is preferable to use a one-touch type optical connector 126 so that the lighting device 120 can be easily coupled and separated from the light supply device 220 at the portion of the optical connector 126. Since the optical connector 126 is already commercially available in many products, and many technical parts are well known, detailed description thereof will be omitted here.

The first and second cases 121 and 122 use fixing bolts 125 to attach to opposite sides of the fixing lever 111 and the moving lever 112 to which the first and second cases 121 and 122 are respectively attached. At least one through hole h 'is formed at the side surfaces of the first and second cases 121 and 122, and a fastening hole h is formed at the side surfaces of the fixing lever 111 and the moving lever 112 corresponding thereto. . In the first embodiment, the fixing bolt 125 is used as a means for firmly attaching the first and second cases 121 and 122 to the fixing lever 11 and the moving lever 112, respectively. However, in order to facilitate detachment and attachment rather than firmness, an adhesive double sided tape may be used. If one of the first and second cases 121 and 122 and the fixing lever 11 and the moving lever 112 are magnetic metals, magnetic tape may be used.

Here, the key element constituting the lighting device 120 is the optical fiber 123. One side of the optical fiber enters the first case 121 and is exposed to the light emitting surface 223 of the first case 121. That is, one side of the first case 121 and the optical fiber forms the light emitting part 421 of the lighting device 120. In addition, the other side of the optical fiber is connected to the optical connector 126 to form a light receiving portion 423 to receive light from the light source 127. The middle portion of the optical fiber 123 forms a light transmitting part 422 for transmitting light. That is, the optical fiber 123, which is a body, may be divided into a light emitting part 421, a light receiving part 423, and a light transmitting part 422 according to its function.

Figure 4 is a perspective view of a second embodiment of a surgical retractor with an illumination function according to the present invention. Compared with the first embodiment of the present invention, the illumination device is made of an optical fiber, one end of the optical fiber constitutes the light emitting portion 421, the other end of the light receiving portion 423, the middle portion of the light emitting portion 421 By configuring the light transmission unit 422 connecting the light receiving unit 423 and the basic components are the same. However, there is a difference in the attachment position of the lighting device 130 and the configuration of the light emitting unit 421.

In the second embodiment of the present invention, the lighting device is a surface emitting lighting device 130 that emits light in a relatively large area, and is mounted on the lower surface of the fixed lever 111 and the moving lever 112. That is, the upper surfaces of the third case 131 and the fourth case 132 of the surface light emitting lighting device 130 are attached to the lower surface of the fixing lever 111 and the moving lever 112, respectively. The connection means of the surface light emitting lighting device 130 may use a fixing bolt, an adhesive tape, an adhesive, and a magnetic adhesive tape as in the first embodiment described above.

5A and 5B are a perspective view and a cross-sectional view showing the configuration of the surface light emitting lighting device 130 used in the second embodiment of the present invention. As shown in the figure, a plurality of bundles of optical fibers 123 enter the case 131. In this case, the case 131 has a rectangular shape having a wide bottom surface and a thin thickness so as to emit surface light. In addition, the bottom surface of the case 131 includes a transparent light emitting surface 133 so that light emitted from the optical fiber 123 inside the case 131 can be emitted outside the case 131, that is, to the surgical site. The bundle of optical fibers 123 in the case 131 is spread in the width direction. Each optical fiber 123 is entangled in the form of a fabric while orthogonal to each other with a plurality of fibers 323 having a thickness substantially the same as that of the optical fiber 123. Therefore, the optical fiber 123 is bent and twisted as shown in Fig. 5B, and the bent portion 123b, which is each bent portion, is formed. That is, a plurality of U-shaped bends 123b are formed in one optical fiber 123, and the total reflection condition is broken in the plurality of bends 123b to emit light. As a result, the plurality of optical fibers 123 are laid out on the horizontal plane, and light is emitted from the plurality of bends 123b to the outside through the light emitting surface 133 disposed below, thereby achieving surface emission.

In the surface emitting illumination device 130 as described above, in order to increase the surface brightness uniformity of the surface emission, it is preferable that the light emitting surface 133 uses an optical film having a diffusion property. In addition, due to the structure in which the optical fiber 123 is woven with the fiber material 323, the upper curved portion 123c is formed on the opposite side of the light emitting surface 123. At this time, it is preferable to form a reflective surface 135 on the surface facing the light emitting surface 133 to send the light emitted through the upper curved portion 123c to the light emitting surface 133. In the present embodiment, the reflective surface 135 is attached to the lower surface of the fixed lever 111 and the moving lever 112 of the traction device 110. When the fixing lever 111 and the moving lever 112 include a metal having good reflection performance, since the light emitted from the upper curved portion 123c is well reflected by the metal and is concentrated toward the light emitting surface 123, the reflective surface It is not necessary to provide 135.

In the surgical retractor provided with the illumination device of the present invention, it can be selectively used as a light source such as a light emitting diode (LED), a halogen phosphor. However, the present invention is not limited thereto and may be used as long as it can emit light by applying power.

In addition, the case and the cover and the like exposed to the outside of the present invention is not only harmless to the human body, it is preferably made of synthetic resin or metal that is not deformed by high temperature and high pressure.

Embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical spirit of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms.
