BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a handle structure of a surgical endoscope, and more particularly, to a handle structure of a surgical endoscope inserted into a body through a part of a body incised for the treatment of a lumbar disease such as a herniated disc or spinal stenosis .

Generally, typical diseases of the lumbar spine include intervertebral disc herniation, which causes discs (intervertebral discs) between the lower bones to protrude outward to touch the surrounding nerves, and joints or ligaments thicken to compress the spinal canal, There is a stenosis of the spinal canal that causes pain by touching the nerves passing through it.

In the past, a method of laparotomy was performed in which a lumbar disc herniation and spinal stenosis were treated for the treatment of pain, and the pain-induced area exposed to the outside through the laparoscope was removed using a surgical tool.

However, the open surgical procedure is complicated and requires a long time to recover from the surgery, and there is a high incidence of sequelae at the surgical site and a wide surgical margin remains in the operator's body. there was.

Recently, a procedure using a spine endoscope has been performed to solve the problem of the open surgery.

In this study, we used a spinal instrument to measure the size of the spinal canal, which was inserted into the vertebral body and inserted the surgical device into the incision, There is an advantage that the operation is performed quickly, the recovery speed of the operator is quick after the operation, and the operator does not have a large operation mark left in the body of the operator.

Conventionally, however, there is no separate gripping means capable of gripping a practitioner in the spinal column, so that the practitioner controls the spinal column in a state in which the CCD camera coupled to the spinal column is gripped to maintain a very unstable posture, So that the procedure is performed in an unstable state.

Further, the CCD camera fastened to the vertebrae is bulky and bulky, which makes it difficult for the practitioner to grasp and handle with stability, and furthermore, it is separated from the vertebra due to its own weight.

In addition, since the position of the arm of the practitioner holding the vertebra is changed according to the insertion depth of the vertebra in the past, it is difficult for the practitioner to hold the posture for a long time while holding the vertebra, There is a problem that the continuity of the procedure is deteriorated.

FIG. 1 is a perspective view showing a surgical endoscope according to an embodiment of the present invention, and FIG. 2 is a sectional view showing a surgical endoscope according to an embodiment of the present invention.

1 and 2, a surgical endoscope 100 (hereinafter, referred to as 'surgical endoscope 100') according to an embodiment of the present invention includes a body And a body 10 which is inserted into the body through a portion thereof.

The main body 10 is formed in a linear pipe shape and a surgical device (for example, a forcep, a laser fiber, or the like) is provided inside the main body 10 along the longitudinal direction A working channel 11 of a tunnel type which can be inserted and moved is formed.

On the other hand, the main body 10 may have different diameters depending on the purpose of use.

More specifically, when the surgical endoscope 100 is intended for treatment of herniated disc, the main body 10 must be inserted into the body and then approach the disc, so that irritation is not transmitted to the nerve bundle and the fibrous tissue So that it can be formed in the minimum size. For example, for the treatment of herniated disc herniation, the main body 10 is formed to a diameter of 6 mm, and the working channel 11 disposed inside the main body 10 may be formed to have a diameter of 3 to 3.2 mm have. Alternatively, when the surgical endoscope 100 is intended for the treatment of spinal stenosis, the main body 10 is inserted into the inside of the body, and then, without approaching the disk, is positioned outside the nerve bundle, Only a part of the tissue is removed, so that it can be formed in the maximum size. That is, the body 10 manufactured for the treatment of spinal stenosis has a shorter insertion depth than the body 10 manufactured for the treatment of the herniated disc herniation. Accordingly, since the probability of interference with the nerve bundle and the fibrous tissue is low, it can be formed to have a larger diameter than that of the main body 10 designed for the treatment of herniated disc herniation. For example, for the purpose of treating spinal stenosis, the body 10 may be formed with a diameter between 6 and 15 mm. Accordingly, the diameters of the working channels 11 disposed inside the main body 10 may be varied according to the size of the main body 10, so that the device for large-diameter surgery can be used.

In addition to the working channel 11, a cleaning channel (not shown) may be formed in the main body 10 for spraying cleaning water such as saline to clean the blood of the affected area and thereby ensure the field of view. In addition, an optical fiber (not shown) for irradiating illumination light may be disposed on a portion other than the space occupied by the working channel 11, the cleaning channel, and a camera module 20 to be described later.

In addition, the main body 10 may be provided with a connector 13.

More specifically, a guide rail 17 is formed on the outer surface of the main body 10 and protrudes outside the main body 10 to guide the movement of the grip 30 along the longitudinal direction. A guide groove 31 may be formed on the inner surface of the handle 30 corresponding to the guide rail 17.

Although the guide rail 17 is formed on the outer surface of the main body 10 and the guide groove 31 is formed on the inner surface of the handle 30 in the present embodiment, The guide grooves 31 are not limited to these, and may be applied to structures opposite to each other. That is, the guide rails 17 may be formed on the inner surface of the handle 30, and the guide grooves 31 may be formed on the outer surface of the body 10 corresponding to the portion where the guide rails 17 are formed.

Therefore, the handle 30 can be moved to any position of the guide rail 17, and the rotation can be restricted by the guide rail 17.

In addition, a rolling member 37 may be further provided on the inner surface of the handle 30.

5, a rolling member 37 is provided on the inner surface of the handle 30 where the guide groove 31 is formed. The rolling member 37 contacts the outer surface of the guide rail 17 to perform rolling motion when the handle 30 is moved . For example, the rolling member 37 is formed in a spherical shape and can be disposed on the inner surface of the handle 30 so as to face each other. Here, a receiving groove corresponding to the outer surface of the rolling member 37 may be formed on the inner surface of the handle 30 so that the rolling member 37 can be rotatably received.

Therefore, the handle 30 can move smoothly and smoothly through the rolling motion of the rolling member 37 described above. In addition, the operator can easily move the handle 30 even when the operator does not apply a large force.

The grip portion 30 may be provided with a fixing portion 33 for fixing the grip portion 30 to any position of the guide rail 17.

6, the fixing portion 33 selectively contacts the outer surface of the guide rail 17 through the elastic force of the first elastic member 333 provided on the handle 30 through the handle 30 Or the like.

More specifically, the fixing portion 33 includes a pressing member 331 which is arranged so as to be linearly movable in a direction perpendicular to the longitudinal direction of the guide rail 17 through the knob portion 30, A first elastic member 333 for returning the pressing member 331 which has been supported on the guide rail 17 to the original position and which is supported on the guide rail 17 in a sexual manner, And a support member 332 for supporting the end portion of the member 331. [

Further, the fixing portion 33 may be formed in a structure in which the fixing portion 33 is caught by the outer surface of the guide rail 17 and can be restricted from moving.

7, the fixing portion 33 is provided with the above-described pressing member 331, the first elastic member 333, and the supporting member 332, And a second elastic member 335 elastically supporting the member 334 and the rotation engaging member 334.

The rotation latching member 334 can be rotatably disposed on the inside of the handle 30 with a serrated engagement means on one side. Here, the other side of the rotation latching member 334 may be disposed in contact with the pressing member 331. [ The rotation engaging member 334 is selectively urged to the urging member 331 so that it can be caught by the teeth 171 formed on the outer surface of the guide rail 17 or can be separated from the teeth 171. [

For example, one surface of the tooth 171 may be formed to be inclined with respect to the outer surface of the main body 10, and the other surface of the tooth 171 may be formed perpendicular to the outer surface of the main body 10. One surface of the engaging means formed on one side of the rotation engaging member 334 is formed in a shape corresponding to the other surface of the tooth 171 and the other surface of the engaging means is formed in a shape corresponding to one surface of the tooth 171 . Therefore, the handle 30 can be moved rearward (rightward in Fig. 7) even when the rotation latching member 334 is in contact with the teeth 171. [ On the contrary, the handle 30 can be moved forward (in the leftward direction in Fig. 7) only when the rotation engaging member 334 is spaced apart from the teeth 171. [

The second elastic member 335 can elastically support the rotation engaging member 334 and return the rotation engaging member 334 separated from the tooth 171 to the original position. For example, the second elastic member 335 may be a return spring to which an elastic force acts in the rotation direction of the rotation latching member 334. [

Further, a gripping groove 35 may be formed in the grip 30.

Referring to FIG. 1, a plurality of gripping grooves 35 may be formed on the outer surface of the handle 30 along the longitudinal direction so that the rest of the finger, other than the thumb, may be seated.

When the movement is completed The grip portion 30 can be fixed at an arbitrary position by pressing the fixed portion 33 using the end portion of a finger (e.g., a stop or a ring finger) that is seated in the grip groove 35. [

At this time, the gripping grooves 35 may be formed to face in a predetermined direction.

Referring to FIGS. 1 and 4, a plurality of gripping grooves 35 formed on the handle 30 may be formed to face the center axis CA of the working channel 11. Here, the center axis CA refers to an arbitrary center line passing vertically through the center of the working channel 11 and the camera module 20 with reference to Fig.

That is, even if the main body 10 is rotated in an arbitrary direction during the procedure, the plurality of gripping grooves 35 are formed in the center of the work channel 11 and the camera module 20 so that the operator can confirm whether or not the main body 10 rotates. And may be formed so as to face the direction coinciding with the axis CA.

Therefore, the practitioner can recognize the rotation direction of the main body 10 by confirming the rotation direction of the gripping grooves 35 only by gripping the grip portion 30, State. For example, the main body 10 may be in a normal position when the plurality of gripping grooves 35 are oriented at 12 o'clock with reference to Fig.
