THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE SUBJECT MATTER AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

TECHNICAL FIELD
[001] The present disclosure relates generally to a field of medical instruments and more particularly to an endoscopic device having an improved and compact distal tip.
5 BACKGROUND
[002] Endoscopic devices for surgical or diagnostic procedures are already known. Endoscopes have gained widespread acceptance in the medical community because they provide a means for performing surgery with minimal trauma to the patient while allowing the physician to view the
10 internal anatomy of the patient. Over the years, many endoscopes have
been developed and classified according to specific applications, such as
ureteroscope, cysto-scope, colonoscopes, upper gastrointestinal
endoscopes, and the like. The endoscope are inserted through a natural orifice in the body. A conventional endoscope is generally an instrument
15 with a handle and an insertion part. Various working components for
observation are provided such as an optical or electronic imaging system and the like. The working components are placed at a distal end of the insertion part. The handle connected with a lever is used to operate the multiple function related to endoscopic device.
20 [003] The endoscope has two ends one is a proximal end and another is a
distal end. A physician inserts the distal end into a patient’s body through a natural orifice to diagnose or treat a disease state of the patient using the working components at the distal end of the insertion part. The proximal end remains outside the patient’s body and typically connects to an
25 eyepiece of the observer, video monitor, or other equipment. The insertion
part uses a complex lens system for transmitting the image from the distal

tip of the endoscope to a viewer. The maneuverability of an endoscope and
its suitability for accessing narrow and delicate regions of the body are in
part determined by the size of the endoscope tip, which in turn is
determined by the sizes of various components the tip contains.
5 Conventional endoscopes have a blunt distal end face, where the light
source and imaging sensor terminate. Furthermore, while performing the
laser lithotripsy, a laser probe is inserted through the working channel. If a
biopsy is performed, then the laser probe has to be removed and another
biopsy device is introduced in the working channel of the
10 endoscope. Based on the prior art cited there is a requirement of such an
instrument to integrate all such ports on a single distal tip of the endoscope.
SUMMARY
[004] Embodiments of the present disclosure present technological
15 improvements as solutions to one or more of the above-mentioned technical
problems.
[005] In an embodiment of a present invention, an endoscope distal tip is
disclosed. The endoscope distal tip includes a camera, a laser channel, an
irrigation port, a working channel port, and an LED. The camera provides
20 real-time images during surgery. The laser channel is placed at a particular
orientation with respect to the camera. The laser channel provide passage
of a laser probe. The laser channel protrudes the laser probe at a
predetermined angle towards the camera. The irrigation port is placed in
proximity to the camera and aligned with the laser tip. The irrigation port
25 ensures a continuous flow of saline water and is used to pass instruments,
accessories, and laser fibers. The working channel port is placed opposite the camera. The working channel port extracts a fragments, dust, and an

organic substances. During an operation, the endoscope distal tip is
inserted through the natural orifice to a target organ. The camera captures
the real-time images of an infected area to locate the position and depth of
an organic substance. The irrigation port fills the infected area with saline
5 water, and the laser channel protrudes the laser probe to break the organic
substances. The working channel extracts the fragments, dust, and the organic substances from the target organ.

[0013] Some embodiment's of this disclosure, illustrating all its features, will now be discussed in detail. The words "comprising," "having,"
20 "containing," and "including," and other forms thereof, are intended to be
equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items. It must also be noted that as used herein and in the appended claims, the singular forms
25 "a," "an," and "the" include plural references unless the context clearly
dictates otherwise. Although a distal tip, similar or equivalent to those described herein can be used in the practice or testing of embodiments of

the present disclosure, the exemplary, endoscope distal tip is now described.
[0014] Various modifications to the embodiment will be readily apparent
to those skilled in the art and the generic principles herein may be applied
5 to other embodiments. For example, although the present disclosure will be
described in the context of an endoscope distal tip, one of ordinary skill in the art will readily recognize that a system can be utilized in any other endoscopic devices, to provide easy and painless insertion of the endoscopic distal tip. Thus, the present disclosure is not intended to be
10 limited to the embodiments illustrated but is to be accorded the widest
scope consistent with the principles and features described herein. [0015] An endoscope is a device, in which a physician inserts the distal end into a patient’s body through a natural orifice or an artificial incision to diagnose or treat a disease state of the patient using the working
15 components at the distal end of the insertion part. The endoscope has two
parts a proximal end and a distal end. The proximal end remains outside the patient’s body and typically connects to an eyepiece, video monitor, or other equipment. The distal end part is an insertion part that uses a complex lens system for transmitting the image from the distal tip of the endoscope
20 to a viewer. The maneuverability of an endoscope and suitability for
accessing narrow and delicate regions of the body are in part determined by the size of the endoscope tip, which in turn is determined by the sizes of various components the endoscope tip contains. In one embodiment, the endoscope is disclosed. The endoscope has different
25 parts, an insertion part i.e. a distal part, an unlock button, and a handle
coupled to a lever. The insertion part has a distal tip, a bending section, and

an insertion tube. The disposable part includes an insertion parts, a housing, and an unlock button.
[0016] The distal tip is coupled to the insertion tube, which is further
attached to a housing. The Housing has a unlock button for engaging and
5 dis- engaging the disposable portion with the handle. The handle is coupled
to the lever. The lever is configured to provide multiple operations. [0017] In prior art, an endoscope is either a rigid endoscope or a flexible endoscope. Typically, the rigid endoscope uses a relay lens system. In case of flexible endoscope, a bundle of fiber optics, or an objective lens system is
10 used. In case of both rigid and flexible conventional endoscopes, the lens
and fiber optic system is relatively expensive. In some embodiments, the endoscope’s discrete illuminators such as light-emitting diodes (herein referred to as LEDs) are used to provide illumination. During the procedure navigating an endoscope through a passageway of a targeted organ is
15 difficult. An obscuring of the examination field with an endoscope is a
common problem, typically caused by bleeding or the release of other fluids from the excision site. The blood or other fluids released prevents the user from clearly observing the examination field. [0018] A conventional endoscopes have a blunt distal end face, where the
20 light source and imaging sensor terminates. During surgery of a laser
lithotripsy, a distal tip of an endoscope comprising a laser probe is inserted through the working channel. As a biopsy is performed, then a distal tip of an endoscope comprising a laser probe has to be removed and another device is introduced in the working channel of the endoscope.
25 [0019] In an embodiment, the endoscope distal tip comprises a camera, a
laser channel, an irrigation port, a working channel port, and an LED or arrangement of LED’s. The camera is square-shaped and is used to capture

the real-time images. The laser channel is circular shaped having a
predefined diameter. The laser channel is used to protrude the laser probe
with a laser tip. The laser channel is placed at a particular orientation with
respect to the camera to provide a clear view. A laser tip of the laser probe
5 protrudes at an angle inclined toward the camera for better depth
perception. The laser channel is aligned with the irrigation port. The irrigation port and the working channel are having circular shapes of different predefined diameters. The irrigation port is placed in proximity to the camera. The irrigation port ensures a continuous flow of saline water.
10 The working channel port is placed opposite to the camera. The working
channel port is used to extract the fragments, dust, and the organic substances. The LED is one of a rectangular shape and a circular shape. The LED is placed separately on either side of the camera. The LED is used for illumination.
15 [0020] In an embodiment, the different forms of the endoscope distal tip are
used as per the requirement during surgery. A group of endoscope distal form consists of a spherical form, a hemispherical form, and a half-mooned form. In the hemispherical form of a distal tip, the laser probe is placed opposite to the camera. The irrigation port is placed in proximity with the
20 camera and the tip of the laser probe is aligned with the irrigation port. The
light-emitting diode (herein referred to as LED) is placed on either side of the camera and aligned with the camera. In another embodiment, a light-emitting diode (herein referred to as LED) is placed on either side of the camera.
25 [0021] In the spherical form of the distal tip, the LED is compactly arranged
with the camera. The irrigation port is placed in proximity with the camera and the tip of the laser probe is aligned with the irrigation port. The

spherical form of the distal tip provides easier insertion and better
advancement in the infected area of a target organ. In the half-moon form
of the distal tip, the LED is compactly arranged with the camera. The
irrigation port is aligned with the camera. And the irrigation port is in
5 proximity to the camera, and the laser channel is aligned with the irrigation
port. The half-moon form of the distal tip provides better extraction of the fragments, dust, and the organic substances along with the saline water. [0022] During operation, the endoscope distal tip is inserted through the natural orifice to a target organ. The camera captures the real-time images
10 of the infected area to locate the position and depth of an infected portion.
The irrigation port fills the infected area with saline water. Then laser channel protrudes the laser probe with the tip at an inclined angle towards the camera for better depth perception. As the tip of the laser probe locates the position of the alien element, the laser breaks the organic substances
15 into fine particles. The working channel is used to extract the fragments,
dust, and the organic substances along with the saline water.
[0023] The endoscope distal tip has the camera, the laser channel, the irrigation port, the working channel port, and the LED. The irrigation port and the working channel port are separate to provide saline water and
20 extraction of a fragment, dust and an organic substances simultaneously.
[0024] Referring now to the drawings, particularly by their reference numbers, figure 1 illustrates an ureteroscope device 100. The ureteroscope device 100 comprises a reusable portion particularly a handle 102 and a disposable portion 104. The disposable portion 104 has a distal end 106 and
