Sheath device and endoscopic system having the same {SHEATH APPARATUS AND ENDOSCOPE SYSTEM HAVING THE SAME}

The present invention relates to a sheath device in which an endoscope device and a treatment device are coupled, and an endoscope system including the same.

Endoscopic systems can generally be divided into endoscopy for examining organs through the oral cavity or anus and minimally invasive surgery for inserting an endoscope and surgical instruments by making a minimal skin incision.

Minimally invasive surgery is a surgical method that minimizes scars caused by surgery by reducing incisions during surgery. One example of minimally invasive surgery is laparoscopic surgery. Laparoscopic surgery is a method of performing surgery by making several small holes in the abdomen and inserting an optical instrument such as an endoscope and surgical instruments into the holes.

In laparoscopic surgery or arthroscopic surgery, an endoscope that is firmly formed in a straight line is inserted into the body, and surgery is performed by manipulating surgical instruments outside the patient's body. At this time, after making a small hole in the skin, a sheath device is inserted into the body so that optical instruments such as an endoscope and surgical instruments can enter and exit.

On the other hand, in the case of conventional minimally invasive surgery, there was a problem in that several parts of the skin had to be incised in order to insert an optical instrument such as an endoscope and a surgical instrument for surgery into the body.

Here, as shown in FIG. 7 , the handle portion 11a of the endoscope device 11 may extend along the first reference line L1 when the sheath device 100 is viewed from the front. . In addition, the first and second communication holes 121 and 122 of the guide part 120 may be arranged side by side to lie on the second reference line L2 perpendicular to the first reference line L1. That is, the heights of the first and second communication holes 121 and 122 may be arranged on the same line when the sheath device 100 is viewed from the front.

In the case of a conventional optical instrument such as an endoscope and a surgical instrument, the shape of the surgical instrument cannot be clearly observed through the endoscope due to a refraction phenomenon caused by bodily fluids such as blood present in the body. According to the configuration of the sheath device 100 of the present invention, the endoscope device 11 and the treatment device 12 are arranged to be at the same height, so that the endoscope device 11 in which refraction occurs due to bodily fluid Even in an actual use environment, the appearance of the treatment device 12 can be observed more clearly. As a result, the sheath device 100 of the present invention has the advantage that more rapid and precise surgery can be performed because the appearance of the treatment device 12 and the affected area can be clearly observed using the endoscope device 11.

Meanwhile, the sheath device 100 may include a first dial unit 114 and a second dial unit 115 .

The first dial unit 114 is rotatably formed along the circumference of the body unit 110 in the circumferential direction. A stopper (not shown) formed to block the opening of the second communication hole 122 may be provided in the first dial unit 114 . As the first dial part 114 rotates on the outer circumferential surface of the body part 110, the second communication hole 122 may be opened or closed.

Similar to the first dial unit 114, the second dial unit 115 is rotatably formed along the circumference of the body unit 110 in the circumferential direction. The second dial unit 115 may be formed to engage with the endoscope device 11 as it rotates on the outer circumferential surface of the body unit 110 . Accordingly, when the endoscope device 11 is coupled to the sheath device 100, the state in which the endoscope device 11 is coupled to the sheath device 100 can be stably maintained by rotating the second dial unit 115. there is.

Meanwhile, the first insertion hole 111 and the first communication hole 121 may be disposed at the center of the body portion 110 when the sheath device 100 is viewed from the front. Accordingly, since the endoscope device 11 providing an image of the affected area during surgery is disposed in the center of the body portion 110 constituting the body of the sheath device 100, the operation of the endoscope device 11 can be performed more intuitively. has the advantage of being

Meanwhile, an end of the guide part 120 through which the first communication hole 121 is opened may be inclined downward at a predetermined angle α toward the body part 110 as shown in FIG. 5 . That is, one end of the guide part 110, when viewed from the side, goes from the upper side to the lower side so that the angle of view of the optical part 11b is formed toward the lower side of the guide part 110. ) may be formed inclined to approach. Accordingly, the angle of view of the optical part 11b of the endoscope device 11 that is exposed through the end of the guide part 120 inclined downward and observes a target can be secured. As shown in FIG. 9 , the optical portion 11b of the endoscope device 11 may be formed to face downward at a predetermined angle β with respect to the front.

That is, when the sheath device 100 is viewed from the bottom in a state in which the endoscope device 11 is coupled to the sheath device 100, a part of the optical portion 11b of the endoscope device 11 extends toward the guide portion 120. The end of may be formed to be seen through the downwardly inclined structure and the cutout 123.

According to the structure of the guide unit 120 as described above, the field of view of the affected area obtained through the optical unit 11b of the endoscope device 11 is inclined downward at a predetermined angle with respect to the front, so that the affected area is farther away during surgery. Since it can be observed from a distance, it is possible to secure a more effective view of the affected area.

Meanwhile, the protrusion 11c1 of the endoscope device 11 is inserted into the body portion 110 when the optical portion 11b of the endoscope device 11 is inserted into the first insertion hole 111 of the body portion 110. A groove 113 may be formed. The groove 113 may guide the mounting position of the endoscope device 11 . The protrusion 11c1 may protrude toward one end of the optical portion 11b.

In addition, the groove 113 of the body part 110 is a first groove 113a or a second groove 113b disposed on both sides of the first insertion hole 111 based on the first insertion hole 111. can be any one of In addition, the protrusion 11c1 of the endoscope body 110 is also one of the first protrusion 11c1a and the second protrusion 11c1b disposed on both sides of the optical unit 11b based on the optical unit 11b. can be

The first protrusion 11c1a and the second protrusion 11c1b may be spaced apart from each other by 180 degrees. According to the structure of the first and second protrusions 11c1a and 11c1b disposed at symmetrical positions around the optical portion 11b, the endoscope device 11 is coupled to the body portion 110 of the sheath device 100 In this state, the movement of the endoscope device 11 to rotate about the first insertion hole 111 can be more stably prevented.

Also, the groove 113 of the body 110 and the protrusion 11c1 of the endoscope device 11 may be disposed on the first reference line L1.

Meanwhile, referring to FIG. 5 , the end of the guide part 120 may have a single inclined surface 124 formed to be inclined downward toward the body part 110 . Here, the first and second communication holes 121 and 122 of the guide part 120 may be formed to open on the single inclined surface 124 . That is, the first and second communication holes 121 and 122 formed on the single inclined surface 124 may be disposed on the same plane. Accordingly, the structure of one end of the guide part 120 where the ends of the endoscope device 11 and the treatment device 12 are exposed can be designed more simply.

Meanwhile, the sheath device 100 may further include a first valve unit 131 and a second valve unit 132 .
