Description

Rigid endoscope for concave chest correction surgery with end cap {Pectoscope comprising the cap detachably fixed on the tip}

The present invention relates to a hard endoscope for concave chest correction surgery having an end cap, and more particularly, to an outer tube, an imaging device accommodated in the tube and mounted with a lens to observe the outside, and light to be observed. In the rigid endoscope for correcting concave breasts provided with an illumination device, the one side is open, the opposite side is closed, connected to the outer tube through the open one side is fixed to cover the illumination device and the imaging device from the outside, It is a transparent material, the cap having a columnar shape gradually narrowing the cross-sectional diameter in the advancing direction of the endoscope; provides a rigid endoscope for concave breast correction surgery having a cap at the end characterized in that it is further provided.

Concave breast ( Pectus) Excavatum ) is an abnormality in which the heart is innately excessively depressed. It is the most common congenital malformation of the breastbone. These symptoms are caused by abnormalities in the breast cartilage, where the breast cartilage concave into the chest and dents under the breastbone (usually the lower half or two-thirds) into the chest, and looks symmetrically recessed. Although many are asymmetrical in some. The right side is known to be more recessed, usually from birth and tends to progress with age.

The problem of concave breasts is not small. The important role of the ribs is to protect important organs, such as the heart and lungs, bowing toward the intestines, which can lead to pressure on the heart or lungs, dysfunction and developmental deterioration, and can easily catch a cold. In addition, a sudden swelling of the chest is often noticeable, often leading to serious emotional and psychological disorders during puberty.

Because of this, concave breasts should be treated through surgery at the appropriate time. One of the conventional surgical methods is formed too long than normal to cut out part of the rib which is bent inward and connect both parts. Lavitch surgery, a method that has been around for decades. This surgery requires an incision about 20-30cm in front of the chest, either horizontally or vertically, and is performed by cutting the rib cage and shaping the chest. However, this surgery has a lot of bleeding and a long hospitalization problem, and in 1997, Donald Nuss, a pediatric surgeon in the United States, announced a surgical technique.

This kind of knuckles drills a 1cm hole on each side of the chest and inserts a metal rod shaped like a hanger through it, pushing the curved ribs to the normal shape by using the principle of the lever. If you insert a metal bar for about two or three years, the ribs will harden accordingly, and the shape of the chest will remain normal even when the metal bar is removed.

Furthermore, in recent years, an induction machine for concave chest orthodontic surgery has been devised so that the endoscope provided separately to such a metal rod can be inserted and operated more conveniently. Using the inducer, in the case of a naus operation, a passage through which the orthodontic metal rod can pass through the chest cavity can be secured in advance. By observing the inside of the thoracic cavity with an endoscope, by securing a passage, there is an advantage of not only preventing the bleeding or damage to the organs inside the thoracic cavity, but also confirming the damage immediately. This is disclosed in Korean Patent Publication No. 0740193.

However, the induction machine has to insert the endoscope separately, and the process of handling the induction machine and the process of handling the endoscope are separated separately, there is a problem that the handling process is not easy.

In addition, although the patent includes an observation unit, the observation unit is made of a transparent body so that it is easy to observe, and has not been considered at all about the problem of optical interference that may occur during illumination or photographing process.

In particular, the observation unit is installed due to the following problems. In other words, the edges of the inducers have corners, so when they must penetrate narrow passages between delicate tissues, there is a risk that the edges of the induction cause tissue damage, e. Is passed between the ribs, and there is a possibility of damaging these organs in the process of being drawn out to the other side of the body via the lungs and heart. The patent is to apply the observation using the endoscope. By the way, the observation unit has a risk of generating diffuse reflection or the like in the process of shooting and illumination using the endoscope.

On the other hand, as disclosed in the prior art, there is a problem that the tubing (transparent body) is seated at the end of the inductor, in which case the end diameter is increased, and thus the endoscope is more difficult to pass. Therefore, there is a need for improvement of the inducer or endoscope end to reduce the risk of tissue damage during the procedure.

The present invention has been made to solve the above problems, the present invention is provided with a cap on the end of the endoscope, the cap is equipped with a window in the front, by mechanically or optically processing the window, thereby improving the optical stability of the endoscope The objective is to ensure clear vision and to prevent tissue damage during surgery.

In order to achieve the above object, the present invention provides a rigid endoscope for concave chest correction, comprising an outer tube, an imaging device accommodated in the tube and mounted with a lens for observing the outside, and an illumination device for irradiating light to the observed area. One side is opened, the opposite side is closed, and fixed to the outer tube through the open one side to cover the lighting device and the imaging device from the outside, transparent material, the cross-sectional diameter gradually narrowed in the advancing direction of the endoscope Cap having a pillar-shaped to lose; provides a rigid endoscope for concave chest correction surgery having a cap at the end characterized in that it is further provided.

The inside of the closed surface of the cap is preferably provided with an insert of an opaque color or opaque material integrally, or separately attached to the inside of the closed surface.

It is preferable that the closed side of the cap is partially opened, and the open portion is equipped with a window made of glass or polymer hard material.

Edge of the window is preferably tapered to form an inclination angle of 35 to 55 degrees around the axis penetrating the endoscope.

The outer tube is provided with a stepped end so that the outer diameter of the cross section narrow in the end direction, the cap is inserted and fixed so that the end of the open portion is in contact with the stepped jaw, the cap is the outer diameter equal to or greater than the outermost diameter of the outer tube It is preferable to have.

According to the present invention as described above, the cap is provided at the end of the endoscope, the cap is mounted to the front window, by mechanically or optically processing the window, to ensure the optical stability of the endoscope to ensure a clear field of view The effect is expected.

In addition, the present invention is expected to work to prevent the damage to the tissue during surgery by processing the end of the cap to be the columnar shape of the front optical narrowing to exclude the sharp edge as much as possible.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments and the accompanying drawings.

1 illustrates a cross-sectional view of an endoscope end and a detachable cap according to an embodiment of the present invention. As shown, the endoscope is coaxially arranged with an imaging path in the center and an illumination path around. That is, the imaging path is a video camera 106 having a sensor 101, a driving circuit 102, a near infrared (NIR) band block filter 103, an objective lens 104, and a protective window 105 in sequence. Is implemented by an imaging device, wherein each component of the video camera is arranged coaxially. All of the components of the video camera 106 are embedded in the inner metal tube 108 of the metal, the end of the inner tube 108 is partially protruded from the outer tube 109, the outer tube 109 and the inner tube ( 108, there will be a step. Since the outer tube 109 is required to apply pressure to the sternum, a metal is generally used in the sense that the outer tube 109 is made of a hard material, but other hard materials may be employed according to the progress of technology. Since the inner tube 108 should also protect the imaging device, a rigid material is preferably used.

The illumination path is implemented by an illumination device comprising a fiberglass bundle 107 divided into three parts surrounding the imaging path, wherein the fiberglass bundle 107 is branched into three, for example, each branched glass Since the fibers irradiate light in different directions, it is possible to prevent shadows from being generated by surrounding tissues, especially during imaging at short working distances, thereby ensuring enemy visibility.

That is, when light is irradiated from one glass fiber to generate a shadow, the light irradiated from another glass fiber removes the shadow.

Cap 112 is introduced to smooth out all exposed surfaces of the endoscope end and is a feature of the present invention.

The cap 112 is a tubular shape, one direction is opened to be extrapolated detachably to the endoscope, and formed of a transparent material.

On the other hand, it is also possible to open the closed portion opposed to the open portion of the cap 112 manufactured in this way, and to finish by attaching a transparent hard material such as glass or acrylic to the open portion (window). It will be described later.

When the cap 112 is mounted on the outer tube 109, the diameter of the endoscope diameter measured at the outermost side of the outer tube 109 and the cross section of the cap 112 may be configured to have the same diameter. . That is, the outer diameter of the outer tube 109 and the outer diameter of the cap is preferably configured to be the same. In this case, the edge portion such as the stepped jaw 111 provided in the endoscope before applying the cap 112 is concealed, and thus it is possible to prevent the damage of the tissue caused by the edge such as the stepped 111 during surgery.

As shown in Figure 1, the end of the cap 112 is preferably manufactured in the form of a column whose cross-sectional diameter is gradually narrowed at a portion based on the direction of the endoscope to facilitate insertion and passage into the body. . However, it is also possible to have a taper shape in which the cross-sectional diameter gradually narrows overall. The cap 112 is more firmly supported by the protrusion 110 of the outer tube 109, and a groove portion (not shown) corresponding to the protrusion 110 may be formed on the inner circumferential surface of the cap 112. Cap 112 is preferably molded from a medical grade thermoplastic elastomer (TPE) having a suitable hardness.

On the other hand, as shown in FIG. 2, back reflections of the illumination light 113 occur at the closed surface of the cap 112 adjacent to the protective window 105, whereby a portion of the illumination light 113 is generated. The silver transmitted light 114, a part of the retro-reflected light 115 is formed, of which the retro-reflected light 115 is introduced into the protective window 105, the problem of whitening the image may occur. Although this bleaching does not impair all the uses of the cap 112, in some cases, the use of the cap 112 may be restricted.

In order to overcome this problem, as shown in Figure 3, the cap 112 is preferably made to have a black ring insertion hole 116 of the same material as the cap 112. The insertion hole 116 is an opaque color, preferably black, and essentially blocks the possibility of generating the retroreflected light 115 shown in FIG. 2.

The insertion hole 116 may be formed integrally with the cap 112, or may be separately formed and attached. In the case of integrally formed with the cap 112, only the insertion hole 116 should be colored. However, if the surface material of the front portion of the cap 112 is not sharp enough, the image observed via the cap 112 will still be in a state of scattering and distortion. This problem can be solved by the cap 112 body being made of TPE, providing a window 117 as described above, and adopting the window 117 as glass or other high definition material. On the other hand, the edge of the window 117 may be provided with a coloring portion 118 to be colored in an opaque color, preferably black by a coating method or the like to function as the insertion hole 116.

FIG. 5 shows a cap 112 on which a window 117 of another embodiment according to the present invention is mounted, wherein the corner 119 of the window 117 shows that afterglow is back reflected into the window 117. It is manufactured obliquely to minimize, allowing the window to be fixed in the cap housing. It was experimentally confirmed that the edge inclination was markedly reduced when the corner inclination was set in the range of 35 to 55 degrees about the through axis of the window. Thus, the angle has its critical significance.

The window 117 should be sized appropriately, the outer diameter of which should be defined in such a way that no light shielding occurs for the specimen appearing on the object plane 120 and that the imaging path is not shielded. . That is, the illumination point on the target surface 120 should be larger than the field-of-view (FOV) of the imaging device, and the angle-of-view (AOV) 121 may be used to prevent image non-uniformity. It should be decided in consideration.

Although specific embodiments of the invention have been described above, it will be obvious that the same may be varied in many ways by those skilled in the art. Such modified embodiments should not be understood individually from the technical idea or viewpoint of the present invention, and these modified embodiments should be included in the claims of the present invention.
