Description

Endoscope for joint {ENDOSCOPE FOR ARTHROSCOPY}

The present invention relates to an endoscope for a joint, and more particularly, to an endoscope for a joint that examines the inside of the joint, but suppresses the expansion of the incision, and smoothly secures the field of view.

In general, an endoscope is a type of optical device, and is largely divided into an industrial endoscope for checking the interior of a narrow space such as pipes or shipbuilding, and a medical endoscope for internal inspection of a human body.

A medical endoscope is a device that visually checks and diagnoses the inside of the human body by being directly inserted into the human body to obtain image information about the surroundings.

On the other hand, unlike in the past, when a procedure was performed through direct skin incision and joint incision for a disease or injury of a joint, nowadays, it is possible to perform diagnosis and surgery simultaneously using an arthroscopy, which is a high-tech medical equipment.

In arthroscopic surgery using a medical endoscope, special imaging (CT, MRI) is performed by inserting an arthroscopy with a special small camera into the joint using a small hole without incision, and then observing the inside of the joint through a monitor, etc. Even lesions that are not identified by the method can not only be accurately diagnosed, but also surgery can be performed at the same time.

However, the conventional arthroscopy has a problem in that it takes a long time and is inferior in accuracy because it is difficult to organize and remove substances located in the peripheral part when performing a procedure on a joint region. Therefore, there is a need to improve this.

The background technology of the present invention is published in Korean Patent Application Publication No. 2014-0133248 (published on November 19, 2014, title of invention: multifunctional arthroscope).

The handle portion is a handle body that can be gripped by a user; A handle adjustment unit mounted on the handle body and connected to the camera unit to move the camera unit; And a handle guiding portion formed on the handle body portion, mounted on the injection portion, and guiding the fluid injected from the injection portion to the needle portion.

The cable part is detachably attached to the handle part and is connected to the display part.

The injection unit may include an injection coupling unit detachably attached to the handle unit; An injection passage part connected to the injection coupling part and forming a three-way passage; An injection opening and closing part formed in the injection passage part and selectively opening and closing the injection passage part; And an injection cover part covering the injection passage part.

The needle portion is a needle pipe portion mounted on the handle portion; A needle inclined portion extending from the needle pipe portion and bent to have an inclination in the needle pipe portion; And a needle tip portion formed at an end portion of the needle pipe portion and having an inclined surface to cut the body.

The camera unit may include a tube unit inserted into the needle unit and movable; A lens unit that acquires and processes an image signal at an end of the tube unit; A plurality of optical fibers that are inserted into the tube to transmit light; And a light source unit connected to the optical fiber unit and generating light.

The guide part includes a guide mounting part surrounding an outer circumferential surface of the camera part; And a plurality of guide protrusions protruding from the guide mounting portion, contacting the needle portion to maintain a gap with the needle portion, and guiding the fluid to be moved.

In the endoscope for joints according to the present invention, after the needle is inserted into the body, the camera unit is moved forward to photograph the inside of the body, thus preventing damage to the camera unit when the needle unit is inserted into the body, and without interference with the needle unit after the needle unit is inserted into the body. Filming can be done.

That is, the angle of view applied to the camera unit 50 is usually 120 degrees, and the angle of view of 240 degrees can be secured through the rotation of the camera unit 50. In addition, it is possible to secure a wide viewing angle even if the entire needle portion 40 is not rotated 360 degrees by setting the viewing angle diagonally by the inclination angle of the needle inclined portion 42 without photographing only the front inside the joint.

The needle tip portion 43 is formed at the end of the needle pipe portion 41, and an inclined surface is formed to cut the body. As an example, the inclination angle of the inclined surface of the needle tip part 43 may be variously set according to the slide movement distance and diameter of the camera part 50.

6 is an exploded view schematically showing a camera unit in the joint endoscope according to an embodiment of the present invention, and Fig. 7 is a cross-sectional view schematically showing the camera unit in the joint endoscope according to an embodiment of the present invention. 6 and 7, the camera unit 50 according to an embodiment of the present invention includes a tube unit 51, a lens unit 52, an optical fiber unit 53, and a light source unit 54. do.

The tube part 51 is inserted into the needle part 40 and moved. As an example, the tube part 51 is embedded in the needle tube part 41 and is coupled with the adjustment connection part 122. Accordingly, when the control button unit 121 is moved forward, the tube unit 51 connected to the control connection unit 122 is moved forward so that the front end of the tube unit 51 may be exposed to the outside of the needle tube unit 41. .

The lens unit 52 is mounted on the front end of the tube unit 51 to obtain an image signal. As an example, the lens unit 52 includes one or more glass lenses or plastic lenses, and each lens may be arranged by combining a spherical surface and an aspherical surface. That is, the number and shape of the lenses may be variously set according to the viewing angle formation goal. The lens unit 52 may be connected to the substrate to process an image signal.

In the tube part 51, the tube moving part 511 and the tube photographing part 513 may be made of a rigid material, and only the tube connection part 512 may be made of a soft material. In addition, the tube connection part 512 may have a corrugated shape to enable shape deformation.

The tube moving part 511 is connected to and moved with the handle part 10. For example, the tube moving part 511 may pass through the needle tube part 41, and one end may be coupled to the adjustment connection part 122. Accordingly, when the control button unit 121 is operated, the tube moving unit 511 coupled with the control connection unit 122 may be moved forward.

The tube connection part 512 connects the end of the tube moving part 511 and the end of the tube photographing part 513. For example, the tube connection part 512 is made of a silicone or rubber material, and has a tubular shape so that the tube moving part 511 and the tube photographing part 513 may be inserted.

The tube photographing unit 513 is connected to the end of the tube connection unit 512 and the lens unit 52 is mounted. For example, when the tube moving part 511 is moved forward, the tube connecting part 512 may be embedded in the needle inclined part 42 and deformed. In addition, the tube photographing unit 513 may be exposed to the outside through the needle tip unit 43 to obtain an image signal of the lens unit 52.

Meanwhile, the tube part 51 may further include a tube holding part 514. The tube holding part 514 protrudes outward from the outer circumferential surface of the tube connection part 512 and is in contact with the needle part 40, thereby maintaining a gap between the tube part 51 and the needle part 40. For example, the tube holding part 514 may be integrally formed with the tube connection part 512, and may be in close contact with the inner wall of the needle pipe part 41 to maintain a gap between the needle pipe part 41 and the tube connection part 512. As a result, the passage of the fluid moving between the needle pipe part 41 and the tube part 51 is maintained, so that a stable fluid supply may be achieved. In addition, when the tube holding part 514 is evenly disposed along the outer circumferential surface of the tube connecting part 512, the fluid can be evenly discharged along the outer circumferential surface of the tube part 51.
