Description

endoscopy

[0001] The present invention relates to an endoscope, and more particularly, to an endoscope in which a disposable part and a reusable part are detachably provided so that the disposable part can be replaced and used.

[0002]

[0003] A medical endoscope is a device that is inserted directly into the internal tissue of the human body to check the condition of the affected area or perform a procedure.

[0004] A typical endoscope features a flexible insertion tube with an articulating assembly at the end, allowing for control of the insertion direction during insertion into the body. A distal end body equipped with an image sensor and a light source is provided at the end of the articulating assembly. A handle body may be provided at the other end of the insertion tube. The handle body is connected to an image processing device (not shown) via a separate cable and connector.

[0005] The handle body has dials and buttons used to adjust the direction of the joint assembly and for operation.

[0006] A pair of dials are arranged to adjust the direction of movement of the distal end body in the longitudinal direction of the insertion tube, up and down and left and right. A sprocket and a chain are provided inside the handle body to convert the rotational motion of the dial into linear motion. The chain is connected to the end of the joint assembly via a separate wire. Consequently, the rotation of the dial is converted into linear motion of the wire through the sprocket and chain, and the joint assembly bends according to the linear motion of the wire. Thus, the operator of the endoscope can control the direction of movement of the distal end body during the process of inserting the insertion tube into the human body.

[0007] Because endoscopes are inserted into the human body, thorough hygiene management is essential, and they must be cleaned and disinfected before and after each examination or surgery. In some cases, reusing the parts that are actually inserted into the body, such as the insertion tube and joint assembly, may be impossible or undesirable. In this case, conventional endoscopes, which are constructed as a single unit, require the entire endoscope device to be replaced, creating the problem of requiring replacement. Furthermore, even if reuse is possible, cleaning and disinfection procedures can be performed more easily if only parts, rather than the entire endoscope, can be removed.

[0008] In this regard, U.S. Patent Publication No. US2014 / 0142389A discloses an endoscope in which an insertion part and an operating part are detachably connected.

[0009] However, since the above endoscope is equipped with channels in the operating section that can be used multiple times, there is a limitation that the operating section may become contaminated if contaminants leak from the replaceable insertion section.

[0010] In addition, the above endoscope has multiple channels arranged adjacently, so when the insertion part and the operating part are separated, contaminants may flow into the adjacent channels, which may cause inconvenience in that the operating part itself must be cleaned.

[0011]

[0012] The present invention was created to improve the problems of conventional endoscopes as described above, and its purpose is to provide an endoscope in which an operator can easily attach and detach a disposable part and a reusable part.

[0013] In addition, the purpose is to provide an endoscope in which the used biopsy channel can be disposed of separately from the reusable part after using the disposable part.

[0014] In addition, the purpose is to provide an endoscope that can prevent contaminants remaining in a disposable part from flowing into a reusable part after using the disposable part.

[0015]

[0016] In order to achieve the above-described purpose, the endoscope according to the present invention comprises: a disposable part having an illumination photographing part and an insertion tube; a reusable part detachably connected to the disposable part and configured to bend the insertion tube according to an operation knob and an operation of the operation knob; and a disposable suction part detachably connected to the reusable part and configured to accommodate a channel therein.

[0017] At this time, the disposable suction unit may be equipped with a suction valve that opens and closes the channel.

[0018] The above channel may include a biopsy channel having one end connected to the suction valve and the other end detachably connected to the disposable part; and a suction channel connecting the suction valve and a suction pump.

[0019] Meanwhile, the reusable portion may accommodate a supply channel through which air or liquid flows.

[0020] In addition, the disposable suction unit may include a first suction unit body having one longitudinal side detachably coupled to the disposable unit; and a second suction unit body extending along a direction intersecting the longitudinal direction of the first suction unit body.

[0021] Meanwhile, the disposable suction unit may further include a suction unit handle that protrudes from the outer surface of the second suction unit body.

[0022] Meanwhile, the disposable part can be combined with the disposable suction part while the reusable part is combined.

[0023] Meanwhile, the disposable suction part and the disposable part can be formed integrally.

[0024] At this time, the disposable suction part and the disposable part can be connected in an elastically deformable manner.

[0025] Meanwhile, the above-mentioned multi-use part may include a grip guide part that guides the grip position on the outer surface.

[0026] Meanwhile, in order to achieve the above-mentioned purpose, the endoscopic component according to the present invention can be detachably coupled to a reusable part equipped with an operating knob.

[0027] At this time, the endoscopic component according to the present invention includes a first suction body that accommodates a biopsy channel therein; and a second suction body that extends along a direction intersecting the longitudinal direction of the first suction body and accommodates a suction channel therein.

[0028] In addition, the endoscope component according to the present invention may further include a suction handle that is formed to be retractable and protrudes from the outer surface of the second suction body.

[0029] In addition, the endoscopic component according to the present invention may further include a suction valve that connects the biopsy channel and the suction channel according to operation.

[0030] In addition, the endoscopic component according to the present invention further includes a disposable part having an illumination photographing part and an insertion tube; and the first suction part body can be provided integrally with the disposable part.

[0031] At this time, the first suction body may be formed of an elastic material.

[0032]

[0033] As described above, the endoscope according to the present invention has the effect of allowing the operator to combine the disposable part and the disposable suction part with a simple operation of inserting them into the reusable part.

[0034] In addition, after using the disposable part, the operator can separate the disposable suction part from the reusable part and dispose of it separately, thereby improving the hygiene of the reusable part.

[0035] In addition, after using the disposable part, the disposable part and the disposable suction part are provided as one unit, so that contaminants remaining in the biopsy channel can be prevented from flowing into the supply channel provided in the reusable part.

[0062]

[0063] FIG. 1 is a perspective view illustrating an endoscope according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating an endoscope according to an embodiment of the present invention viewed from a different angle, FIG. 3 is an exploded perspective view illustrating an endoscope according to an embodiment of the present invention, FIG. 4 is a cross-sectional view illustrating a reusable part in an endoscope according to an embodiment of the present invention, FIG. 5 is a bottom view illustrating a reusable part in an endoscope according to an embodiment of the present invention, FIG. 6 is a perspective view illustrating a disposable suction part in an endoscope according to an embodiment of the present invention, and FIG. 7 is a drawing illustrating a channel in an endoscope according to an embodiment of the present invention.

[0064] Referring to FIGS. 1 to 7, an endoscope (1) according to one embodiment of the present invention may be a disposable endoscope. Specifically, the endoscope (1) according to one embodiment of the present invention includes a reusable part (100) and a disposable part (200). In this case, the reusable part (100) and the disposable part (200) may be detachably coupled to each other.

[0065]

[0066] The reusable part (100) is provided so that the operator can operate it. The reusable part (100) can be provided so that the operator can grip it and operate it. The reusable part (100) can bend the disposable part (200) through the operator's operation.

[0067] The disposable part (200) is provided so that it can be inserted into the human body by manipulation of the reusable part (100) and photograph the inside of the human body. The disposable part (200) can be inserted into the human body, and is provided so as to be bendable by manipulation of the reusable part (100) so that it can move along the internal structure of the human body, and can irradiate light into the inside of the human body and photograph it.

[0068]

[0069] An endoscope (1) according to one embodiment of the present invention may further include a connector adapter and a universal code.

[0070] Specifically, the endoscope (1) includes a connector adapter for connection to an external device, and the connector adapter can be connected to a reusable part (100) via a universal cord. The external device connected to the connector adapter may be an image processing device. Through this, an image captured by the disposable part (200) can be displayed on the external image processing device. Through this, an operator can operate the reusable part (100) while viewing the image captured by the disposable part (200) on the image processing device.

[0071]

[0072] The reusable part (100) includes a reusable part housing (110), an operating knob (120), a power transmission part, and a reusable part plate.

[0073] The reusable housing (110) is provided so that the operator can grip it. For example, the reusable housing (110) may be formed in a hollow cylinder shape, and a grip guide portion (112) may be formed on the outer surface of the reusable housing (110). At this time, the grip guide portion (112) may be formed with a plurality of curved grooves so that the position of the operator's hand is guided. In addition, the grip guide portion (112) may be formed with a plurality of protrusions or grooves to prevent the operator's hand from slipping.

[0074] The reusable part housing (110) may be provided with an operation knob (120), a plurality of valves (185, 330), and a button portion (113). For example, an operation knob (120) may be rotatably coupled to one longitudinal side of the reusable part housing (110), and a plurality of valves (185, 330) and a button portion (113) may be arranged around the operation knob (120). At this time, the operation knob (120), the plurality of valves (185, 330), the button portion (113), and the disposable part (200) may be arranged in opposite directions with respect to the grip guide portion (112). That is, when the operation knob (120) and the plurality of valves (185, 330) and the button portion (113) are arranged on one side in the longitudinal direction of the reusable portion housing (110), the disposable portion (200) can be coupled to the other side in the longitudinal direction of the reusable portion housing (110).

[0075] With this configuration, the operator can press the valve (185, 330) and button (113) while holding the phage guide portion (112) with the palm of his / her hand, and can easily turn the operating knob (120) with the hand opposite to the hand holding the reusable portion housing (110).

[0076] Meanwhile, the reusable part housing (110) can accommodate a power transmission unit for driving the disposable part (200) inside.

[0077] The power transmission unit can rotate in conjunction with the operating knob (120) to transmit the rotational power of the operating knob (120). Various types of power transmission means can be applied to the power transmission unit. For example, the power transmission unit can include a plurality of sprockets and a chain. As another example, the power transmission unit can include a plurality of timing gears and a timing belt. As yet another example, the power transmission unit can have a plurality of gears meshed with each other.

[0078] Below, we will explain the structure consisting of sprockets and chains.

[0079] A power transmission unit (130, 140, 150) according to one embodiment of the present invention may include a driving sprocket (130), a driven sprocket (140), and an operating chain (150).

[0080] At this time, a driving sprocket (130) that is linked to the rotation of the operating knob (120), a driven sprocket (140) that is linked to the driving sprocket (130) and rotates, and an operating chain (150) that connects the driving sprocket (130) and the driven sprocket (140) can be accommodated inside the multi-use housing (110).

[0081] For example, a driving sprocket (130) may be arranged on one longitudinal side of the interior of the reusable housing (110), and a driven sprocket (140) may be arranged on the other longitudinal side. In addition, an operating chain (150) may be arranged along the longitudinal direction inside the reusable housing (110).

[0082] Meanwhile, the reusable housing (110) can accommodate a supply channel (180) inside.

[0083]

[0084] The operating knob (120) can control the disposable part (200) by rotating according to the user's operation. When the operating knob (120) is rotated according to the user's operation, the sprocket (130, 140) can be rotated in conjunction with the rotation of the operating knob (120).

[0085] The operating knob (120) may be configured to include two or more knobs. For example, the operating knob (120) may be provided in a form in which a first knob (121) and a second knob (122) are stacked in the vertical direction. The first knob (121) and the second knob (122) are respectively connected to a first driving sprocket (131) and a second driving sprocket (132) to be described later, and are configured to rotate independently of each other. The first knob (121) and the second knob (122) have a form in which multiple teeth protrude so that the operator can easily grip and rotate them.

[0086] Meanwhile, the first knob (121) can rotate independently while the second knob (122) remains stationary. Similarly, the second knob (122) can rotate independently while the first knob (121) remains stationary. The first knob (121) controls the up and down movement of the lighting photographing unit (210). That is, when the first knob (121) is turned clockwise or counterclockwise, the end of the lighting photographing unit (210) bends upward or downward accordingly. The second knob (122) controls the left and right movement of the lighting photographing unit (210). That is, when the second knob (122) is turned clockwise or counterclockwise, the end of the lighting photographing unit (210) bends to the left or right accordingly.

[0087] Meanwhile, in another embodiment, the first knob (121) can control the left and right movement of the lighting photographing unit (210), and the second knob (122) can control the up and down movement.

[0088] In this way, the rotation direction of the lighting photographing unit (210) can be arbitrarily adjusted by operating the first knob (121) and the second knob (122). Depending on the embodiment, it may be necessary to fix the lighting photographing unit (210) in a state where it is bent at a specific angle, and for this purpose, a fixing knob (123) is provided on the upper side of the second knob (122). When the fixing knob (123) is rotated, the first driving sprocket (131) and the second driving sprocket (132) are fixed so as not to rotate, and accordingly, the end of the lighting photographing unit (210) can also be maintained in a fixed state.

[0089] A first drive sprocket (131) and a second drive sprocket (132) are mounted on the lower portions of the first knob (121) and the second knob (122) so as to be rotatable in conjunction with the rotation of the first knob (121) and the second knob (122), respectively. In addition, an operating chain (150) that moves in conjunction with each of the driving sprockets (130) is provided. The operating chains (150) are responsible for the up-and-down movement and left-right movement of the lighting and photography unit (210), respectively, and these can move independently of each other.

[0090] Specifically, a first knob shaft (126) is coupled to the inside of the first knob (121), so that the first knob (121) and the first knob shaft (126) can rotate together. In addition, a second knob shaft (127) is coupled to the inside of the second knob (122), so that the second knob (122) and the second knob shaft (127) can rotate together. At this time, the first knob shaft (126) can be coupled to the first drive sprocket (131). And, the second knob shaft (127) can be coupled to the second drive sprocket (132).

[0091] Meanwhile, when the reusable housing (110) is placed closer to the ground than the operating knob (120), the first knob (121) may be positioned higher than the second knob (122). In addition, the fixed knob (123) may be positioned higher than the first knob (121).

[0092] Meanwhile, the power transmission unit (130, 140, 150) may include a first power transmission unit (131, 141, 151) and a second power transmission unit (132, 142, 152). At this time, the second power transmission unit (132, 142, 152) may be positioned higher than the first power transmission unit (131, 141, 151). Specifically, the second driving sprocket (132) may be positioned higher than the first driving sprocket (131). That is, the second knob (122) and the second driving sprocket (132) may be positioned between the first knob (121) and the first driving sprocket (131).

[0093] The operating chain (150) can connect the driving sprocket (130) and the driven sprocket (140). The operating chain (150) can transmit the rotational power of the driving sprocket (130) to the driven sprocket (140). When the driving sprocket (130) rotates through the operating chain (150), the driven sprocket (140) can rotate in conjunction therewith.

[0094] The operating chain (150) may include a first operating chain (151) and a second operating chain (152). The first operating chain (151) may connect a first driving sprocket (131) and a second driven sprocket (141). The second operating chain (152) may connect a second driving sprocket (132) and a second driven sprocket (142).

[0095] At this time, the second driven sprocket (142) may be placed above the first driven sprocket (141).

[0096] Therefore, when the first knob (121) is rotated by the user's operation, the first driving sprocket (131) and the first driven sprocket (141) can rotate in conjunction with each other. In addition, when the second knob (122) is rotated by the user's operation, the second driving sprocket (132) and the second driven sprocket (142) can rotate in conjunction with each other.

[0097] Meanwhile, the reusable part (100) may include a reusable part plate (160). The reusable part plate (160) may partition the interior of the reusable part housing (110) into upper and lower sections. For example, the reusable part plate (160) may be formed in a flat plate shape and placed within the reusable part housing (110). In this case, the driving sprocket (130), the driven sprocket (140), and the operating chain (150) may be placed above the reusable part housing (110). In addition, the driving gear (170) and the channel (180) may be placed below the reusable part housing (110).

[0098]

[0099] The driving gear (170) can rotate in conjunction with the rotation of the sprockets (130, 140). Specifically, the driving gear (170) can receive driving force from the driven sprocket (140). At this time, the first driven sprocket (141) can be coupled with the first driving gear (171).

[0100] Specifically, the first driven sprocket (141) may be spline-coupled with the first drive gear (171). Alternatively, the first driven sprocket (141) may be key-coupled with the first drive gear (171). For example, the first driven sprocket (141) may include a sprocket portion coupled with the operating chain (150) and a coupling shaft portion that extends axially downward from the sprocket portion and is coupled with the first drive gear (171). At this time, a key portion that is spline-coupled with the first drive gear (171) may be formed on the outer circumferential surface of the coupling shaft portion. Accordingly, when the first driven sprocket (141) rotates, the first drive gear (171) may also rotate in conjunction.

[0101] Meanwhile, the second driven sprocket (142) may be spline-coupled with the second driving gear (172). Alternatively, the second driven sprocket (142) may be key-coupled with the second driving gear (172). For example, the second driven sprocket (142) may include a sprocket portion coupled with the operating chain (150) and a shaft coupling hole formed at the radial center of the sprocket portion. At this time, the shaft coupling hole may be formed as a hole having a non-circular shape so as to be key-coupled with the connecting shaft (173). In addition, the second driving gear (172) may include a gear portion on which gear teeth are formed and a shaft coupling hole formed at the radial center of the gear portion. Accordingly, the second driven sprocket (142) may be connected to the second driving gear (171) through the connecting shaft (173). Therefore, when the second driven sprocket (142) rotates, the second driving gear (172) can also rotate in conjunction.

[0102] Meanwhile, the first driving gear (171) may be positioned above the second driving gear (172). Accordingly, the first driven sprocket (141) and the first driving gear (171) may be positioned between the second driven sprocket (142) and the second driving gear (172).

[0103]

[0104] Meanwhile, the reusable part (100) may be provided with a channel for supplying air and water to the affected area during the procedure. For example, the channel may be a supply channel (180). In this case, the supply channel (180) may be an air supply channel and / or a water supply channel. The air supply channel and the water supply channel have a roughly cylindrical shape and are hollow inside, so that when combined with the lighting and photographing part (210), they are inserted into the interior of the lighting and photographing part (210) so that water or air, etc. can be stably supplied to the treatment or examination area without leakage.

[0105] Meanwhile, the supply channel (180) may be equipped with a supply valve (185). The supply valve (185) may be exposed to the outside of the reusable housing (110). When the operator operates the supply valve (185), air and water flowing into the disposable unit (200) through the supply channel (180) can be switched.

[0106] The connection terminal may be provided to be electrically connected to the lighting camera unit (210) so that data obtained by a camera, etc., provided at the end of the lighting camera unit (210) can be transmitted to an external device. For example, the connection terminal may be an HDMI terminal for transmitting audio and video.

[0107] The above channel (180) and connection terminal may be positioned lower than the operation chain (150). For example, the channel (180) and connection terminal may be accommodated within the reusable housing (110), but may be positioned further from the operation knob (120) than the operation chain (150).

[0108] At this time, the area where the operation chain (150) moves and the area where the channel (180) and connection terminal are arranged can be distinguished by the multi-use plate (160). The channel (180) of the multi-use part (100) can be connected to the channel (not shown) of the disposable part (200).

[0109] The reusable part (100) includes a connecting part (190). The connecting part (190) can be detachably connected to the connecting part (250) of the disposable part (200). The connecting part (190) can be connected to the hook (251a) of the connecting part (250). Specifically, the connecting part (190) is formed on the outer surface of the reusable part housing (110), and the hook of the connecting part (250) can be received therein.

[0110] Meanwhile, a guide pin may be provided to protrude from the longitudinal end surface of the coupling portion (190) to guide the coupling position with the connecting portion (250). Through this, the user can accurately couple the reusable portion (100) and the disposable portion (200).

[0111] Meanwhile, a gear hole may be formed on the longitudinal end surface of the connecting portion (190). The gear hole may be arranged so that at least a portion of the driving gear (170) passes through it. At this time, when the reusable portion (100) is separated from the disposable portion (200), at least a portion of the driving gear (170) may be exposed to the outside.

[0112] Additionally, a channel connection portion may be provided on the longitudinal end face of the connecting portion (190). The channel connection portion may be arranged at the longitudinal end of the channel (180). Through this, when the reusable portion (100) and the disposable portion (200) are connected, the channel (180) can be connected to the channel (243) of the disposable portion (200).

[0113] Additionally, a connector capable of connecting a connection terminal may be provided on the longitudinal end face of the joint (190). The connector may be provided so that the connection terminal is connected.

[0116] Referring to FIGS. 9 to 12, a disposable part (200) of an endoscope according to one embodiment of the present invention will be described as follows.

[0117] The disposable part (200) is detachably connected to the reusable part (100), and at least a portion of it is inserted into the human body to photograph the inside of the human body.

[0118] The disposable part (200) includes a lighting photographing part (210), an insertion tube (220), a wire (230), and a connecting part (250). At this time, the lighting photographing part (210) is arranged on one side in the length direction of the disposable part (200), and the connecting part (250) is arranged on the other side. In addition, the lighting photographing part (210) and the connecting part (250) can be connected by the insertion tube (220), and at least a part of the wire (230) can pass from the connecting part (250) to the insertion tube (220).

[0119]

[0120] The lighting photography unit (210) is inserted into the human body to irradiate light into the human body and photograph the inside of the human body.

[0121] The lighting shooting unit (210) includes a lighting shooting unit body (211), a lighting module, and a shooting module.

[0122] The lighting photographing unit body (211) forms the exterior of the lighting photographing unit (210) and is configured to be inserted into the human body. For example, the lighting photographing unit body (211) has a lighting module and a photographing module arranged on one longitudinal side, and the other longitudinal side is open so that it can be connected to an insertion tube (220).

[0123] At this time, depending on the embodiment, the lighting shooting unit body (211) can function as a heat dissipation chassis.

[0124] For example, the lighting and photography unit body (211) may be a coil pipe made of spring material and may release heat generated from the lighting module and / or the photography module.

[0125] A lighting module can be attached to the end cap. The lighting module can emit light. The lighting module can include a lighting lens that can emit light when powered. For example, the lighting lens can be an LED (Light Emitting Diode).

[0126] Meanwhile, in this embodiment, multiple lighting lenses may be provided. Specifically, an even number of lighting lenses may be provided in this embodiment. For example, a pair of lighting lenses may be arranged symmetrically. This prevents asymmetry in the illumination of objects at close range and prevents gaps in the illumination.

[0127] At this time, a pair of lighting lenses can have different correlated color temperatures (CCTs). This can be used to create the desired light wavelength distribution.

[0128] Additionally, the lighting module may further include a lighting support member supporting a pair of lighting lenses. The lighting support member may be formed in a flat shape, and may have a pair of tip ends symmetrically extended and bent upward. A pair of lighting lenses may be coupled to the pair of bent extension members.

[0129] For example, the light support unit may be a flexible printed circuit board (PCB). An image sensor may be mounted on the flexible PCB. By utilizing multiple light lenses as the light unit, not only can the illumination intensity be easily controlled, but the amount of light emitted can also be significantly increased compared to conventional halogen lamps, thereby further enhancing the clarity of the image obtained through the image sensor.

[0130] Meanwhile, the photographing module can capture images of the inside of the human body. The photographing module can capture images of the inside of the human body upon receiving power and transmit captured image data. For example, the photographing module may include a camera and an image processing unit. In this case, the camera may be positioned at one end (the tip) of the lighting photographing unit (210) in the longitudinal direction, and the image processing unit may be coupled to the camera to process images received from the camera.

[0131] Through this, the endoscope (1) of the present invention can irradiate light through the lighting module and photograph the inside of the human body through the photographing module while inserted into the human body.

[0132] The end cap may be formed of a transparent material. The end cap may be formed with multiple channel-receiving tubes into which channels (not shown) are inserted. Each channel-receiving tube has a hollow cylindrical shape and is formed with an inner diameter corresponding to the outer diameter of each channel to be inserted. Furthermore, an O-ring may be provided inside to prevent leakage of supplied water or air.

[0133] Meanwhile, the lighting photography unit (210) may be equipped with a connection terminal. The connection terminal may be equipped to correspond to the connection terminal of the reusable unit (100). That is, the reusable unit (100) may be equipped with a male terminal, and the disposable unit (200) may be equipped with a female terminal.

[0134]

[0135] The insertion tube (220) connects the lighting photographing unit (210) and the connecting unit (250), and can be bent according to the operation of the reusable unit (100).

[0136] Specifically, the insertion tube (220) can be bent according to the movement of the wire (230).

[0137] Meanwhile, the insertion tube (220) can accommodate multiple channels (240) and terminals inside.

[0138] The insertion tube (220) may include a bending portion, an adapter, a coil spring, and an insertion tube. At this time, the bending portion may be positioned between a pair of adapters, one of the pair of adapters may be coupled to the lighting photographing portion (210), and the other may be coupled to the connecting portion (250).

[0139] The bending portion can be configured to bend according to the movement of the wire (230).

[0140] The bending portion includes a first bending member and a second bending member that are rotated relative to each other. At this time, the bending portion may have a plurality of first bending members and second bending members arranged alternately. In addition, as the number of first bending members and second bending members increases, the overall length of the bending portion may increase. Therefore, the number of first bending members and second bending members can be adjusted according to the usage conditions of the endoscope (1) to select an appropriate length of the insertion tube (220).

[0141] The first bending member and the second bending member may be provided to rotate relative to each other.

[0142] At this time, a wire (230) can pass through the wire penetration hole formed in the first bending member and the second bending member.

[0143] The adapters can be connected to each of the longitudinal ends of the bending portion. At this time, the adapter located on one longitudinal end can be connected to the lighting photographing unit (210), and the adapter located on the other longitudinal end can be connected to the connecting unit (250).

[0144] At this time, a wire (230) can pass through the wire penetration hole of the adapter.

[0145] Meanwhile, the coil spring may be arranged to surround the outer circumference of the bending portion. That is, the coil spring may be arranged to surround the outer circumference of the first bending member and the second bending member when the first bending member and the second bending member are joined.

[0146] On the other hand, the longitudinal ends of the coil spring can be connected to an adapter. The coil spring can be elastically supported by the spring connecting portions of a pair of adapters. Accordingly, when the bending portion is bent by the operation of the operating knob (120), the coil spring can apply elastic force to restore it to its original position.

[0147] Meanwhile, an insertion tube may be placed on the other longitudinal side of the insertion tube (220). The insertion tube is formed in a bendable tube shape, and a wire (230), a channel (240), and a terminal may pass through the inside. Although not shown, a coil pipe may be provided within the insertion tube to provide elasticity to the insertion tube.

[0148]

[0149] Meanwhile, the wire (230) receives the operating force of the operating knob (120) through the connecting portion (250) and can bend the insertion tube (220) through a linear reciprocating motion.

[0150] The wire (230) may have one longitudinal end coupled to an adapter or a lighting photographing unit (210), and the other longitudinal end coupled to a wire reel (253). At this time, the wire (230) may pass through the wire through-hole of the adapter, the wire through-hole of the first bending member, and the wire through-hole of the second bending member.

[0151] Accordingly, on the side where the wire (230) is pulled, the first bending member and the second bending member can be rotated relative to each other so that the gap between the first bending member and the second bending member becomes narrower. On the other hand, on the side where the wire (230) is released (lengthened), the first bending member and the second bending member can be rotated relative to each other so that the gap between the first bending member and the second bending member becomes wider. Accordingly, the first bending member and the second bending member can form a bent shape.

[0152] A disposable part (200) may be provided with a channel (240). The channel (240) may be accommodated within the insertion tube (220) and the connecting part housing (251). Specifically, the channel (240) may include a biopsy channel (241) and a supply channel (243).

[0153] The biopsy channel (241) can be connected to the lighting photographing unit (210) on one side and detachably connected to the disposable suction unit (300) on the other side. The biopsy channel (241) can provide a path for a tool for collecting tissues of a living body part or organ to move or for a collected sample to flow. Meanwhile, a portion of the biopsy channel (241) can be branched and communicate with a biopsy insertion port through which a tool is inserted. The biopsy insertion port can be blocked by a biopsy cap (255), and the biopsy cap (255) can be removed when the tool is inserted.

[0154] The supply channel (243) can supply air and water to the affected area during the procedure. At this time, the supply channel (243) can supply air and / or water. The supply channel (243) has a roughly cylindrical shape and is hollow inside, so that it can be inserted into the interior of the lighting and photographing unit (210) to ensure that water or air, etc., are stably supplied to the treatment or examination area without leakage.

[0155] The connecting part (250) is detachably connected to the connecting part (190) of the reusable part (100). The connecting part (250) may include a connecting part housing (251), a driven gear (252), and a wire reel (253).

[0156] The connecting part housing (251) can be coupled with the insertion tube (220) on one longitudinal side and detachably coupled with the coupling part (190) on the other longitudinal side. At this time, one longitudinal side of the connecting part housing (251) can be coupled with the other longitudinal side of the insertion tube (220), and the other longitudinal side of the connecting part housing (251) can be provided so as to be detachably coupled with the coupling part (190).

[0157] The connecting part housing (251) may be formed in an overall rectangular cylinder shape, but may be formed in a shape in which the diameter becomes narrower as it goes toward one end (tip) in the longitudinal direction. Consequently, the connecting part housing (251) may be formed in a shape in which one end in the longitudinal direction can be combined with the insertion tube of the insertion tube (220), and thus connected.

[0158] The longitudinal side of the connecting part housing (251) may be provided to be engaged with the coupling part (190).

[0159] Specifically, at least one hook (251a) may be formed to extend from the longitudinal opposite end of the connecting part housing (251). For example, the hooks (251a) may be respectively arranged on two opposing surfaces of the connecting part housing (251). At this time, the hooks (251a) may be coupled to the coupling portion (190) formed on the outer surface of the reusable part housing (110). Specifically, the hooks (251a) may be slidably moved along the outer surface of the reusable part housing (110) and may be received and coupled to a groove formed on the outer surface of the reusable part housing (110).

[0160] At this time, depending on the embodiment, a guide portion may be further formed on the connecting portion housing (251) to guide the position of the connection with the coupling portion (190). At this time, the guide portion may be formed on a surface different from the two surfaces on which the pair of hooks (251a) are respectively formed. For example, the guide portion may be formed to extend from the upper surface of the connecting portion housing (251). Accordingly, when the user couples the connecting portion (250) and the coupling portion (190), the user can distinguish which side is the upper surface and which side is the lower surface, thereby preventing incorrect assembly.

[0161] Meanwhile, a pin receiving groove for receiving a guide pin may be formed on the longitudinal end surface of the connecting part housing (251). Accordingly, a user can connect the coupling part (190) and the connecting part (250) in the correct position.

[0162] Meanwhile, a gear hole may be formed on the longitudinal end surface of the connecting portion housing (251). The gear hole may be arranged so that at least a portion of the driven gear (252) passes through it. At this time, when the reusable portion (100) is separated from the disposable portion (200), at least a portion of the driven gear (252) may be exposed to the outside.

[0163] In addition, a channel connecting portion (251b) may be provided on the longitudinal end surface of the connecting portion housing (251). The channel connecting portion (251b) may be arranged at the longitudinal end of the channel (240). Through this, when the reusable portion (100) and the disposable portion (200) are combined, the supply channel (180) of the reusable portion (100) and the supply channel (243) of the disposable portion (200) may be connected.

[0164] In addition, a connector (251e) capable of connecting a connection terminal may be provided on the longitudinal end surface of the connecting part housing (251). Through this, when the reusable part (100) and the disposable part (200) are combined, the connector (196) of the reusable part (100) and the connector (251e) of the disposable part (200) can be connected to each other.

[0165] As a result, the connecting part housing (251) can be fitted with the coupling part (190). At this time, the driving gear (170) and the driven gear (252) are meshed with each other, the supply channel (180) of the reusable part (100) and the supply channel (243) of the disposable part (200) are connected to each other, and the terminals of the reusable part (100) and the disposable part (200) can be connected to each other.

[0166] The driven gear (252) can receive driving force from the driving gear (170). When the reusable part (100) and the disposable part (200) are coupled, the driven gear (252) can mesh with the driving gear (170). Specifically, the driven gear (252) includes a first driven gear (252a) and a second driven gear (252b). At this time, when the reusable part (100) and the disposable part (200) are coupled, the first driven gear (252a) can mesh with the first driving gear (171), and the second driven gear (252b) can mesh with the second driving gear (172).

[0167] Accordingly, when the first driving gear (171) rotates, the first driven gear (252a) can rotate in conjunction, and when the second driving gear (172) rotates, the second driven gear (252b) can rotate in conjunction.

[0168] Meanwhile, the first driven gear (252a) can receive rotational force from the first driving gear (171) to rotate the first wire reel (253a). In addition, the second driven gear (252b) can receive rotational force from the second driving gear (172) to rotate the second wire reel (253b).

[0169] For example, the first driven gear (252a) may be formed integrally with the first wire reel (253a). In this case, the first driven gear (252a) and the first wire reel (253a) may be formed with a hollow radial center. This can reduce the overall number of parts.

[0170] Meanwhile, the second driven gear (252b) may include a gear portion having gear teeth formed thereon and a shaft portion extending upwardly in the axial direction from the radial center of the gear portion. At this time, the shaft portion may penetrate the hollow of the first driven gear (252a) and the first wire reel (253a). In addition, the axially upper end of the shaft portion may be key-coupled with the second wire reel (253b). Therefore, the second driven gear (252b) and the second wire reel (253b) may be coupled to each other and rotate together.

[0171] Meanwhile, the first driven gear (252a) may be positioned above the second driven gear (252b). In addition, the first wire reel (253a) may be positioned below the second wire reel (253b). That is, the first driven gear (252a) and the first wire reel (253a) may be positioned between the second driven gear (252b) and the second wire reel (253b).

[0172] Meanwhile, the wire reel (253) can move the wire (230) by rotating in conjunction with the rotation of the driven gear (252). The wire reel (253) can include a first wire reel (253a) and a second wire reel (253b).

[0173] At this time, the first wire reel (253a) may include a reel body formed in a cylindrical or cylindrical shape and a wire fixing member positioned radially outward of the reel body to which the wire (230) is fixedly connected. At this time, the reel body may have an axial lower end extending radially outward, and a wire fixing member may be formed extending upward from the radially outer end of the extended portion. Accordingly, the reel body and the wire fixing member may be rotated integrally.

[0174] Therefore, when the first driven gear (252a) rotates, the reel body and wire fixing member rotate together to push or pull the wire (230).

[0175] In addition, the second wire reel (253b) may include a reel body formed in a cylindrical or cylindrical shape, a wire fixing portion (253bb) disposed on the radially outer side of the reel body to which the wire (230) is fixedly connected, and a key portion protruding from the axial lower end of the reel body and coupled with the shaft portion of the second driven gear (252b). At this time, the reel body may have an axial lower end extending radially outward, a wire fixing portion extending upward from the radially outer end of the extended portion, and a key portion protruding downward from the axial lower surface of the reel body. Accordingly, when the second driven gear (252b) rotates, the key portion rotates together, and the reel body and the wire fixing portion may rotate. As a result, the second wire reel (253b) may move the wire (230) by pushing or pulling it.

[0176] Meanwhile, the connecting portion (250) may further include a support shaft (254). The support shaft (254) is formed in a cylindrical shape and is fixedly connected to the connecting portion housing (251), and may penetrate the radial centers of the first driven gear (252a), the second driven gear (252b), the first wire reel (253a), and the second wire reel (253b). Accordingly, the support shaft (254) may provide a rotation axis of the first driven gear (252a), the second driven gear (252b), the first wire reel (253a), and the second wire reel (253b).

[0177] Therefore, according to the present invention, when the user operates (turns) the first knob (121), the first driving sprocket (131) rotates together, the first driven sprocket (141) rotates in conjunction with the first driving sprocket (131) by the first operating chain (151), and the first driving gear (171) rotates together with the first driven sprocket (141). Then, in a state where the reusable part (100) and the disposable part (200) are coupled, the first driven gear (252a) meshed with the first driving gear (171) rotates in conjunction with the rotation of the first driving gear (171), and the first wire reel (253a) rotates integrally with the first driven gear (252a) to move the wire (230) and bend the insertion tube (220).

[0178] In addition, when the user operates (turns) the second knob (122), the second driving sprocket (132) rotates together, the second driven sprocket (142) rotates in conjunction with the second driving sprocket (132) by the second operating chain (152), and the second driving gear (172) rotates together with the second driven sprocket (142). In addition, when the reusable part (100) and the disposable part (200) are coupled, the second driven gear (252b) meshed with the second driving gear (172) rotates in conjunction with the rotation of the second driving gear (172), and the second wire reel (253b) rotates integrally with the second driven gear (252b) to move the wire (230) and bend the insertion tube (220).

[0179]

[0180] Meanwhile, conventional disposable endoscopes have a biopsy channel and a supply channel inside the disposable portion, and a biopsy channel and a supply channel connected to the disposable portion are also provided inside the reusable portion. Consequently, contaminants may leak during the separation process between the disposable portion and the reusable portion.

[0181] In particular, when the biopsy channel and the supply channel are arranged adjacently and the insertion part and the operating part are separated, contaminants from the biopsy channel may flow into the supply channel, causing inconvenience in that the operating part itself must be completely cleaned.

[0182] To address this, the present invention may further include a disposable suction unit (300). The disposable suction unit (300) may be detachably connected to the reusable unit (100) and may accommodate a channel (320) within it. In this regard, the disposable suction unit (300) may be referred to as an endoscopic component. That is, the endoscopic component may be detachably connected to the reusable unit (100).

[0183] The disposable suction unit (300) is described below with reference to FIGS. 1 to 7.

[0184] The disposable suction unit (300) includes a suction unit body (310), a channel (320), a suction valve (330), and a suction unit handle (340).

[0185] The suction body (310) can be detachably coupled with the reusable housing (110). At this time, the suction body (310) can be coupled to the opposite side of the side of the reusable housing (110) on which the adjustment knob (120) is arranged. This prevents interference with the suction body (310) when the operation knob (120) is operated. In addition, when the suction body (310) is coupled to the reusable housing (110), the user holds the suction body (310) and the reusable housing (110) with one hand and operates the operation knob (120) with the other hand, thereby providing an advantage in that the operator can stably hold the suction body (310).

[0186] The suction unit body (310) may include a first suction unit body (311) and a second suction unit body (312). The first suction unit body (311) may be detachably coupled to the disposable unit (200) at one longitudinal side thereof. In addition, the second suction unit body (312) may be integrally connected to the other longitudinal side of the first suction unit body (311), and may be formed to extend along a direction intersecting the longitudinal direction of the first suction unit body (311).

[0187] For example, the first suction unit body (311) may be formed in a tubular shape with a portion open along the longitudinal direction. Specifically, the first suction unit body (311) may be formed in a shape in which a portion facing the reusable unit housing (110) is open. With this configuration, when the suction unit body (310) and the reusable unit housing (110) are combined, a space capable of accommodating a channel (320) may be formed inside the first suction unit body (311).

[0188] At this time, one longitudinal end of the first suction body (311) is formed in an open shape so that the biopsy channel (321) can pass through it. In addition, at least a part of the biopsy channel (321) can be accommodated inside the first suction body (311). In addition, the other longitudinal end of the first suction body (311) can be connected to the second suction body (312).

[0189] A channel support rib (311a) may be formed on the first suction unit body (311). The channel support rib (311a) is formed to protrude from the inner surface (inner circumference) of the first suction unit body (311) and may come into contact with the biopsy channel (321) to support the biopsy channel (321). Therefore, the biopsy channel (321) may be stably supported during use of the reusable unit (100).

[0190] Meanwhile, the second suction body (312) may be formed in a tubular shape with a portion open along the longitudinal direction. Specifically, the second suction body (312) may be formed in a shape in which a portion facing the reusable housing (110) is open. With this configuration, when the suction body (310) and the reusable housing (110) are combined, a space capable of accommodating a channel (320) may be formed inside the second suction body (312).

[0191] At this time, one longitudinal end of the second suction body (312) may be connected to the first suction body. In addition, at least a portion of the suction channel (322) may be accommodated inside the second suction body (312). In addition, the other longitudinal end of the second suction body (312) may be formed in an open shape so that the suction channel (322) may pass through.

[0192] A channel fixing portion (312a) may be formed in the second suction portion body (312). The channel fixing portion (312a) may be formed to protrude from the inner surface (inner circumference) of the second suction portion body (312), and a circular hole may be formed to allow the suction channel (322) to pass therethrough. Accordingly, the suction channel (322) may be stably fixed during use of the reusable portion (100).

[0193] Meanwhile, the first suction body (311) and the second suction body (312) may be formed to have different internal diameters. In addition, the first suction body (311) and the second suction body (312) may be formed to have different protruding heights from the reusable part housing (110) based on the state in which they are coupled to the reusable part housing (110). For example, the first suction body (311) may be formed to have a smaller diameter than the second suction body (312), and the first suction body (311) may have a smaller protruding height from the reusable part housing (110) than the second suction body (312). With this configuration, the first suction body (311) can minimize the volume when coupled to the reusable part housing (110), so that the operator does not feel uncomfortable when holding the reusable part (100). In addition, the second suction body (311) has the effect of securing a space through which a supply channel (180) provided inside the reusable housing (110) can pass.

[0194] Meanwhile, the suction unit body (310) may further be provided with a coupling guide portion (313). The coupling guide portion (313) may be formed to extend from the first suction unit body (311). At this time, based on the state in which the suction unit body (310) is coupled to the reusable unit housing (110), the coupling guide portion (313) may be formed to surround at least a portion of the outer surface of the supply valve (185). Through this, when the operator couples the disposable suction unit (300) to the reusable unit (100), the operator may be guided to intuitively recognize the coupling position.

[0195] The channel (320) is accommodated in a disposable suction unit (300) and detachably connected to a reusable unit (100).

[0196] The channel (320) may provide a passage through which a fluid passes. For example, the channel (320) may be formed in a cylindrical shape so that a gas, liquid, or biological material may pass therethrough.

[0197] The channel (320) includes a biopsy channel (321) and a suction channel (322). The biopsy channel (321) can be connected to a suction valve (330) on one side and detachably connected to a disposable part (200) on the other side. The biopsy channel (321) can be connected to a biopsy channel (243) of the disposable part (200). Therefore, when suction force is applied from a suction pump (not shown), a biological material introduced through the light photographing part (210) can flow.

[0198] A suction channel (322) can connect a suction valve (330) and a suction pump (not shown). The suction channel (322) transmits suction force applied from the suction pump (not shown) to the suction valve (330), and allows air or a substance passing through the biopsy channel (321) to pass through.

[0199] Meanwhile, a suction valve (330) may be placed at a portion where the first suction body (311) and the second suction body (312) are connected to each other. The suction valve (330) may open and close the channel (320).

[0200] Specifically, a biopsy channel (321) and a suction channel (322) can be connected to the suction valve (330). That is, the biopsy channel (321) and the suction channel (322) can be connected to each other through the suction valve (330). Therefore, the operator can connect the biopsy channel (321) and the suction channel (322) to each other by operating the suction valve (330).

[0201] Specifically, when the suction valve (330) is not in operation, the biopsy channel (321) and the suction channel (322) are not connected, and external air can be sucked toward the suction pump (not shown) through the suction channel (322).

[0202] Meanwhile, when the suction valve (330) is operated, the biopsy channel (321) and the suction channel (322) are connected, and the suction power of the suction pump (not shown) is applied to the suction channel (322) and the biopsy channel (321), so that biological materials around the light photographing unit (210) can be sucked.

[0203] Meanwhile, the disposable suction unit (300) of the present embodiment may be provided with a suction unit handle (340). The suction unit handle (340) may be formed to protrude from the outer surface of the second suction unit body (312). The suction unit handle (340) may be provided so that the operator can grip it. For example, the suction unit handle (340) may be formed in the shape of a block or plate that protrudes to a predetermined height. At this time, the suction unit handle (340) may be formed with a protrusion, a groove, or a groove that increases friction to prevent the operator's fingers from slipping.

[0204] Therefore, the operator can easily separate the disposable suction part (300) and the reusable part (100) with just a simple action of pulling the suction part handle (340).

[0205]

[0206] Referring to FIG. 3, the process of assembling an endoscope according to one embodiment of the present invention is described as follows.

[0207] First, the operator can couple the disposable suction part (300) to the reusable part (100). At this time, the operator can hold the suction part handle (340) and couple the suction part body (310) to the channel mounting part (111). At this time, the operator can place the supply valve (185) between the coupling guide part (313) and the suction valve (330) and place the suction channel (322) in the channel guide groove (111a). Then, when the operator presses the suction part body (310) toward the channel mounting part (111), the hook (314) can be coupled to the reusable part housing (110).

[0208] As described above, when the disposable suction part (300) and the reusable part (100) are connected, the connection part (190) can be inserted into the connecting part (250) of the disposable part (200) to connect them. At this time, the operator can align the guide pin with the groove of the connecting part (250) and connect the biopsy channel (321) to the biopsy channel (241) of the disposable part (200). In addition, the supply channel (180) can be connected to the supply channel (243) of the disposable part (200).

[0209] Therefore, according to the present invention, there is an effect that allows the operator to combine the disposable suction part (300) and the disposable part (200) with a simple operation of inserting them into the reusable part (100).

[0210]

[0211] Meanwhile, after the endoscope (1) is used, the operator can pull and separate the disposable part (200) while the reusable part (100) and the disposable suction part (300) are connected. At this time, the operator can release the hook (251a) provided in the connecting part housing (251) and pull and separate the connecting part housing (251) away from the reusable part (100). At this time, the channel (240) of the disposable part (200) can be separated from the channel (320) of the disposable suction part (300) and the supply channel (180) of the reusable part (100).

[0212] Thereafter, the operator can hold the suction handle (340) and pull the stent body (310) away from the reusable housing (110) to separate it. Through this, the channel (320) through which the biopsy material flows can be separated from the reusable housing (100) and disposed of separately.

[0213] Accordingly, according to the present invention, even if the endoscope (1) is used multiple times, only the biopsy channel (241, 321) that may be contaminated can be separated and disposed of, thereby improving the hygiene of the reusable part (100).

[0214]

[0215] Fig. 8 illustrates an endoscope (1) according to a second embodiment of the present invention.

[0216] Meanwhile, in order to avoid repeated explanation, the structure and effect of the endoscope (1) according to the first embodiment of the present invention are the same as those of the first embodiment of the present invention except for the parts specifically described in this embodiment, and thus can be used.

[0217] The disposable suction part (300) of this embodiment is characterized by being formed integrally with the disposable part (200).

[0218] At this time, the disposable suction unit (300) and the disposable unit (200) can be connected in an elastically deformable manner. Specifically, the disposable suction unit (300) may be formed of a material having elasticity, such as a first suction unit body (311). For example, the first suction unit body (311) may be formed of a material including rubber.

[0219] Through this, the first suction body (311) can be elastically deformed.

[0220] Through this, the operator can connect or separate only the reusable part (100) while the disposable suction part (300) and the disposable part (200) are provided as one unit. In this process, the first suction part body (311) can be elastically deformed to protect and support the internal biopsy channel (321).

[0221] Therefore, in this embodiment, it is possible to prevent the biopsy channel, which may be contaminated, from being separated into the disposable suction part (300) and the disposable part (200).

[0222] Therefore, according to the present invention, there is an effect of being able to block contaminants remaining in the biopsy channel from flowing into the supply channel (180) provided in the reusable part (100).

[0223]

[0224] FIG. 13 is a perspective view illustrating an endoscope according to a third embodiment of the present invention, FIG. 14 is a perspective view illustrating a reusable part in an endoscope according to a third embodiment of the present invention, and FIG. 15 is a perspective view illustrating a disposable suction part in an endoscope according to a third embodiment of the present invention.

[0225] Referring to FIGS. 13 to 15, the inner diameter (1`) according to the third embodiment of the present invention is described as follows.

[0226] Meanwhile, in order to avoid repeated explanation, the structure and effect of the endoscope (1) according to the first embodiment of the present invention are the same as those of the first embodiment of the present invention except for the parts specifically described in this embodiment, and thus can be used.

[0227] The disposable suction unit (1300) of the present embodiment may have a first suction unit body (1311) and a second suction unit body (1312) formed of an elastic material. For example, the first suction unit body (1311) and the second suction unit body (1312) may be formed of a material including rubber.

[0228] At this time, a biopsy channel (1321) may be accommodated inside the first suction body (1311). For example, a groove in which the biopsy channel (1321) is accommodated along the longitudinal direction may be formed in the first suction body (1311), and the widthwise diameter of the groove may be formed to be the same as or slightly smaller than the diameter of the biopsy channel (1321). In addition, the diameter of the outer end of the groove may be formed to be smaller than the maximum diameter. Through this, when the biopsy channel (1321) is fitted into the groove, the first suction body (1311) can tighten and support the biopsy channel (1321) by elastic force.

[0229] In addition, a suction channel (1322) may be accommodated inside the second suction body (1312). For example, a groove in which the suction channel (1322) is accommodated along the longitudinal direction may be formed in the second suction body (1312), and the widthwise diameter of the groove may be formed to be the same as or slightly smaller than the diameter of the suction channel (1322). In addition, the diameter of the outer end of the groove may be formed to be smaller than the maximum diameter. Through this, when the suction channel (1322) is fitted into the groove, the second suction body (1312) can tighten and support the suction channel (1322) by elastic force.

[0230] Meanwhile, in the present embodiment, a biopsy channel (1321) and a suction channel (1322) may be connected. In addition, a suction valve (1330) may be connected to one end of the suction channel (1322).

[0231] Through this, when the operator operates the suction valve (1330), the biopsy channel (1321) and the suction channel (1322) are connected, and suction force can be applied to the biopsy channel (1321).

[0232] Meanwhile, a channel mounting portion (1111) may be formed in the reusable housing (1110) so that a suction body (1310) may be fitted thereto, and a channel guide groove (111a) into which the channel is coupled may be formed. At this time, since the suction body (1310) is formed of an elastic material, it may be elastically deformed during the process of being fitted into the suction body (1310), and then restored to be supported by the reusable housing (1110).

[0233] With this configuration, the operator can easily combine the reusable part (1100) and the disposable suction part (1300).

[0234]

[0235] Meanwhile, in the present embodiment, it is also possible for the disposable suction part (1300) and the disposable part (1200) to be formed integrally. Accordingly, the operator can combine the disposable part (1200) and the reusable part (1100) while also combining the disposable suction part (1300).

[0236]

[0237] Although the present invention has been described in detail through specific examples, this is for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and it is clear that the present invention can be modified or improved by a person having ordinary knowledge in the relevant field within the technical spirit of the present invention.

[0238] All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
