BEST MODE

(6) An openable/closable vertebral endoscopic device according to an embodiment of the present disclosure will now be described in detail with reference to the accompanying drawings.

(7) FIG. 1 is an exploded perspective view of an openable/closable vertebral endoscopic device according to an embodiment of the present disclosure, FIG. 2 is a bottom perspective view of a combined openable/closable vertebral endoscopic device according to an embodiment of the present disclosure, FIG. 3 is a cross-sectional view taken along line III-III of FIG. 1, FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3, and FIGS. 5 and 6 are views for explaining an operation of an embodiment of the present disclosure, by magnifying a portion V of FIG. 4.

(8) As shown in FIGS. 1 through 6, the openable/closable vertebral endoscopic device according to an embodiment of the present disclosure includes an endoscope body 1 and a cover member 2.

(9) The endoscope body 1 has a similar structure to an endoscope for use in spine surgery, and obtains a unique effect unexpectable from general endoscopes due to an organic combination of a structure related to a working channel 100 according to the present embodiment with a general endoscope structure.

(10) In other words, as shown in FIG. 1, the endoscope body 1 employed in the present embodiment includes the working channel 100 for providing an access route of a surgical instrument to a diseased area of a human body, wherein the working channel 100 includes an open channel 110 obtained by opening a portion of the working channel 100 such that a portion of the surgical instrument inserted into the human body is exposed to the outside.

(11) A working channel employed in general endoscopes is formed as an enclosed type and thus it is difficult to expect insertion of a surgical instrument having a larger inner diameter than that of the working channel. However, according to the present embodiment, because the working channel 100 employed in the endoscope body 1 is provided with the open channel 110, surgical instruments of various sizes according to different treatments for different patents may access diseased areas through the working channel 100 having an expanded space due to formation of the open channel 110.

(12) The cover member 2 is provided on the endoscope body 1 as shown in FIGS. 1 and 2, and selectively opens or closes the open channel 110 of the endoscope body 1 as shown in FIGS. 5 and 6.

(13) In other words, in order for a surgical instrument according to a treatment required by a patient to be inserted into the working channel 100 of the endoscope body 1, the cover member 2 may close the open channel 110 as shown in FIG. 5 when use of a surgical instrument suitable for the original space of the working channel 100 is required, and may open the open channel 110 to secure an expanded space as shown in FIG. 6 when use of a surgical instrument having a larger size than the original space of the working channel 100 is required.

(14) The openable/closable vertebral endoscopic device having this structure according to an embodiment of the present disclosure includes the open channel 110 formed in the endoscope body 1 to expand the space of the working channel 100 for providing an access route of the surgical instrument to the diseased area of the human body, and opens or closes the open channel 110 by using the cover member 2 according to different treatments required for different patients, thereby enabling rapid and precise surgical operation tailored for a patient. In addition, the openable/closable vertebral endoscopic device having this structure according to an embodiment of the present disclosure may provide a quality medical service from a surgical operator, because angular flexibility of the surgical instrument inserted into the working channel 100 is secured to some degree by the open channel 110.

(15) The cover member 2 may have any of various structures capable of selectively open or close the open channel 110 of the endoscope body 1. However, according to the present embodiment, the cover member 2 is formed to wrap the working channel 100 of the endoscope body 1, as shown in FIG. 3, a closed portion 21 and an open portion 22 are integrally formed as shown in FIG. 4, and the cover member 2 is provided on the endoscope body 1 to be rotatable relative to the endoscope body 1 as shown in FIGS. 5 and 6.

(16) In the present embodiment having this structure, because the cover member 2 rotates at a certain angle with respect to the endoscope body 1, the closed portion 21 and the open portion 22 alternately open or close the open channel 110, and thus the space of the working channel 100 of the endoscope body 1 may be freely expanded even with a simple manipulation by a surgical operator.

(17) The open portion 22 and the closed portion 21 of the cover member 2 are formed by cutting out a circular arc portion corresponding to a certain angle in a circumferential direction, from a cylindrical structure having an empty inside to wrap the endoscope body 1 and extending in one direction.

(18) Because the present embodiment having this structure includes the cover member 2 that has a simple structure and is easily formed, manufacturing costs of products may be reduced, and mass production thereof may be improved.

(19) Because the cover member 2 includes a lever part 23 protruding from the closed portion 21 toward the outside of the closed portion 21 and rotating with the closed portion 21, a surgical operator may more smoothly open or close the open channel 110.

(20) The endoscope body 1 may have any of various structures in which the open channel 110 is formed in the working channel 100. However, according to the present embodiment, the endoscope body 1 may include a working sleeve part 10, a lens part, and a manipulation part 14.

(21) The working sleeve part 10 extends in one axis direction and includes the working channel 100 having the open channel 110, and the lens part is provided on the working sleeve part 10 to enable photographing of a diseased area, and includes not only a lens (not shown) mounted on a leading end of the working sleeve part 10 but also a channel 12 on the lens part's side that provides a moving path of light radiated onto the lens.

(22) The manipulation part 14 is connected to the working sleeve part 10 and is provided with a structure such as a handle held by a surgical operator or a guide that guides insertion of a surgical instrument into the working sleeve part 10, and thus enables the surgical operator to handle the working sleeve part 10 at a location apart from the working sleeve part 10.

(23) In the present embodiment having this structure, because a structure related to the working sleeve part 10 according to the present embodiment is organically combined with the structure of a general endoscope, a product enabling a rapid and precise surgical operation tailored to a patient may be manufactured due to a change in the structure of the working sleeve part 10 without a big change in a conventional endoscope structure, and thus may have an improved quality without causing an increase in the product's prices, thereby contributing to improving medical welfare.

(24) Reference numeral 16 indicates a channel on a cleaning part's side that provides a spraying path for spraying a cleaning solution to a diseased area.

(25) Although various embodiments of the present disclosure have been described above, the present embodiments and the drawings attached to the present specification merely show a part of the technical spirit included in the present disclosure. It will be apparent that modifications and specific embodiments that can be easily inferred by those skilled in the art within the scope of the technical idea are included in the scope of the present disclosure.
