The invention provides an endoscope device with a multi-stage switching design, which can improve inspection efficiency. The endoscope device of the present invention can be applied to surgery, such as debridement of the affected part in the skull, but is not limited thereto.

FIG. 1 is a schematic diagram of an embodiment of an endoscope device 10 according to the present invention. As shown in FIG. 1, the endoscope device 10 includes a suction pipe 110, a grip 150, and a first button 170. Partial inhalation The tube 110 extends into the cavity within the grip 150. As shown in FIG. 1, the grip 150 has a proximal end 150 a and a distal end 150 b. The flushing tube 110 extends from the side of the distal end 150 a into the grip 150, and the other parts of the flushing tube 110 are located outside the grip 150 and facing away. The direction of the end 150b extends.

The portion of the suction pipe 110 protruding into the grip 150 may form different pipes to connect external devices. As shown in FIG. 1, an interface 11 is provided on the grip 150 near the proximal end 150 a. The interface 11 may be a suction interface or a flushing interface. For example, the suction pipe is inserted into the cavity in the grip and connected to the suction port behind the grip to connect an external extraction machine to remove blood clots and blood. In another example, the flushing tube extends into the cavity in the grip and is connected to the flushing port behind the grip to receive, for example, a potion or other therapeutic substance.

In an embodiment, the endoscope device 10 may include a photographing unit to provide an observed image. For example, the photographing unit may be disposed near the mouth of the suction pipe 110 away from the distal end 150b and return the image. As shown in FIG. 1, the grip 150 has a display screen 20 connected to the outside by wires. The picture obtained by the photographing unit can be transmitted to the display screen 20 via a line for the user to read.

As shown in FIG. 1, a first button 170 is provided on the grip 150. The first button 170 is connected to the suction pipe 110. For example, the first button 170 is connected to a portion of the suction tube 110 located in the cavity. Please refer to FIG. 2A to FIG. 2C. 2A to 2C are schematic diagrams of an embodiment of an operation of an endoscope device. As shown in FIG. 2A, the one end of the flushing pipe 110 is a single pipe, and the other end is provided with branched different pipes. In this embodiment, the branched pipe includes a first branch pipe 161 and a second branch pipe 162, and the conduction states of the pipes are controlled by valves 91 and 93, respectively. The first branch pipe 161 may be connected to a suction port on the handle, and the second branch pipe 162 may be connected to a flush port on the handle, for example. On the other hand, the endoscope device is provided with a handle 82 in a grip. One end of the rotary handle 82 is connected to the part of the suction pipe 110 forming a single pipe, and the other end is connected to a first button (not shown). In addition, the handle 82 is electrically coupled to the controller 80, and the controllers 80 control the opening and closing states of the valves 91 and 93. The portion of the flushing pipe 110 forming a single pipe may have a curved shape, for example, and the bending degree may be changed with the rotation of the handle 82 to adjust the flushing. The straw 110 is extended.

The first button can be moved to different operation positions to drive the suction pipe 110 to expand and contract. Specifically, the first button is moved between the rest position, the first operation position, and the second operation position. As shown in FIG. 2A, when the first button is in the rest position, the portion of the flushing pipe 110 forming a single pipe is relatively curved, at this time, the rotary handle 82 has not been rotated, and the controller 80 is open, so that the valve 91 and the valve 93 are closed. Therefore, the first branch pipe 161 and the second branch pipe 162 are not conducted.

As shown in FIG. 2B, when the first button is moved from the rest position to the first operation position, for example, when the first button is pressed for a distance, the suction pipe 110 is extended along the axial direction away from the grip. As shown in FIG. 2B, one end of the rotary handle 82 is pressed by the first button to compress the spring 84 and drive the end connected to the suction pipe 110 to move. The degree of bending of the suction pipe 110 becomes smaller. Accordingly, the portion of the flushing tube 110 exposed outside the grip is increased to a first length. At this time, the controller 80 maintains an open circuit, and the first branch pipe 161 and the second branch pipe 162 are not conducted.

As shown in FIG. 2C, when the first button is moved to the second operation position, for example, the pressing distance is increased by one time from the rest position (refer to FIG. 2A), or from the rest position to the first operation position (refer to FIG. 2B). ), The pressing distance is increased stepwise from the first operation position to the second operation position. At this time, the suction pipe 110 is extended along the axial direction away from the grip. As shown in FIG. 2C, one end of the rotary handle 82 is pressed by the first button to further increase the compression amount of the spring 84, and the end connected to the suction pipe 110 is moved, and the degree of bending of the suction pipe 110 tends to be gentle. Accordingly, the portion of the flushing tube 110 exposed outside the grip is increased to a second length. The second length is larger than the first length. At this time, the controller 80 is closed and opens the valve 91, so that the first branch pipe 161 is conducted. In this way, the suction pipe 110 can be connected to an external extraction machine via a first branch pipe 161 and a suction interface (not shown) to start the suction function of the suction pipe.

Conversely, when the first button is moved from the second operation position to the first operation position, the suction pipe 110 returns from the state shown in FIG. 2C to the state shown in FIG. 2B. Specifically, the first A part of the button is released, so that the end of the rotary handle 82 connected to the first button is stretched by the spring 84 to drive the end of the rotary handle 82 connected to the suction pipe 110 to move, and the degree of bending of the suction pipe 110 becomes larger. Accordingly, the suction pipe 110 is retracted along the axial direction toward the grip, so the length of the suction pipe 110 exposed outside the handle is reduced. At this time, the controller 80 returns to the open circuit, and the first branch pipe 161 and the second branch pipe 162 are not conducted. With this design, the suction pipe can be linked with the first button to control the extended length of the suction pipe and the conduction state of the internal pipe.

3 and 4 are schematic diagrams of another embodiment of an endoscope apparatus 10 according to the present invention. As shown in FIG. 3, the endoscope device 10 includes a tube member 130 connected to one side of the distal end 150 b of the grip 150. The tube member 130 has a contact end 132 protruding beyond the distal end 150b. For example, the contact end 132 may be inspected deep into a human body. The aforementioned suction pipe is sleeved in the pipe fitting. In one embodiment, the flushing tube can be made of plastic material, and the tube can be made of metal material. The externally sleeved metal can guide the suction tube through a hard surface, such as the skull, and use the suction tube for examination and treatment. In other embodiments, the material of the tube can be adjusted according to the treatment site. For example, a plastic material that is more rigid than the suction tube is used to provide certain protection for the suction tube.

In addition, as shown in FIG. 3, the grip 150 of the endoscope device 10 includes the first button 170 as described above and a rocker 180. The first button 170 is connected to the portion of the suction pipe that extends into the grip 150 to control the movement of the suction pipe relative to the pipe member 130 (refer to FIG. 4). The rocker 180 is connected to the pipe member 130 to control the pipe member 130 to bend and swing (refer to FIG. 6).

As shown in FIG. 4, when the first button 170 is pressed, the suction pipe 110 protrudes out of the pipe member 130. In other words, the length of the suction pipe 110 protruding from the contact end 132 beyond the nozzle of the pipe member 130 is adjustable. In this way, the relative distance between the nozzle of the suction tube and other elements (such as a photography unit) in the tube can be adjusted after the tube is extended into the body, so as to provide convenience.

FIG. 5 is a partially enlarged view of an embodiment of the endoscope device. As mentioned earlier, the endoscope device may include a photographing unit to provide an observed picture. In terms of setting, photography The unit is disposed in one side of the tube away from the distal end, that is, near the contact end. Please refer to Figure 5. FIG. 5 is an enlarged end of the tube 130 protruding beyond the distal end. As shown in FIG. 5, a flushing tube 110 is sleeved inside the tube 130 to provide flushing material or to suck blood clots. For example, the flushing tube is inserted into the cavity in the grip and connected to the interface behind the grip to connect an external extraction machine to remove blood clots and blood water; or the flushing tube is received through the interface to receive medicine or other therapeutic substances.

As shown in FIG. 5, a photographing unit 30 is further disposed in the pipe member 130 near the suction pipe 110. Thereby, the scene in the body can be observed by the photographing unit 30 and then treated with the suction pipe 110. In addition, a light source 40 is provided in the pipe member 130 near the suction pipe 110 to provide illumination. The light source is, for example, an optical fiber, and light is emitted by the end of the optical fiber. In other embodiments, the light source may be an LED lamp.

FIG. 6 is a schematic diagram of an embodiment of the bending of the pipe member 130. Referring to FIGS. 3 and 6, the tube member 130 has a bendable portion 134 at a position close to the contact end 132. Specifically, a plurality of slits are formed on the outer surface of the pipe member 130 at the position of the bendable portion 134 to make the place more flexible. A rocker 180 is provided on the grip 150. As shown in FIG. 6, the bending situation of the pipe fitting 130 can be controlled with the aforementioned rocker. As shown in FIG. 6, the pipe fitting 130 is displaced from the original position (shown by the dotted line) toward one of the axis A of the pipe fitting 130 Side bending. Thereby, the rocker can control the pipe from bending from the bendable portion, for example, swinging up, down, left, and right to increase the field of view of the photographing unit.

FIG. 7A to FIG. 7C illustrate another example of the first button 170 driving the flushing pipe 110. FIG. 7A shows a situation where the first button 170 is at a rest position, and FIG. 7B and FIG. 7C are schematic diagrams of the first button 170 at different operation positions. As shown in FIG. 7A, the endoscope device 10 includes a connecting rod 50 which is disposed in a cavity of the grip 150. In this embodiment, the connecting rod 50 includes a first connecting rod 51 and a second connecting rod 52. The first connecting rod 51 and the second connecting rod 52 are connected to each other (for example, in a pivoting manner). One end of the first connecting rod 51 is connected to the suction pipe 110 and one end of the second connecting rod 52 is connected to the fixing seat 55. As shown in FIG. 7A, the end portion 51a of the first coupling rod 51 is connected to the punch The suction tube 110 has an end portion 51b of the first coupling rod 51 and an end portion 52b of the second coupling rod 52 connected to each other and having an included angle with the first coupling rod 51. An end portion 52 a of the second coupling rod 52 is connected to the fixing seat. The bottom 172 of the first button 170 is the connection point between the first connecting rod 51 and the second connecting rod 52. A spring 53 is provided at an end portion 51 a of the first coupling rod 51 and an end portion 52 a of the second coupling rod 52. The spring 53 can expand and contract according to the operation of the link 50.

In addition, as shown in FIG. 7A, the suction pipe 110 is connected to the pipe 160 in a direction extending away from the pipe member 130. The pipe 160 is connected to the interface 11 behind the grip 150. In addition, the endoscope device 10 includes a first rod body 60 provided in the cavity. The first rod body 60 has a first end 61 and a second end 62 opposite to the first end 61. The first end 61 is closer to the first button 170 than the second end 62, and the second end 62 is a clamping pipe 160.

The first button 170 can be moved between the rest position, the first operation position, and the second operation position as described above. As shown in FIG. 7A, when the first button 170 is in the rest position, the bottom 172 of the first button 170 is spaced apart from the first end 61 of the first lever 60. In other words, the bottom 172 of the first button 170 is spaced apart from the upper surface 63 of the first rod 60. At this time, the second end 62 of the first rod body 60 clamps the pipe 160, so the pipe 160 is not conductive. It should be added that the so-called rest position refers to the natural position when the first button is not pressed. At this time, the distance between the bottom of the first button and the upper surface of the first rod body is the largest. The first operation position refers to a position substantially the same as the horizontal height of the upper surface of the first rod body. The second operation position refers to a position lower than the horizontal height of the upper surface of the first rod body.

As shown in FIG. 7B, when the first button 170 is moved from the rest position to the first operation position, the separation distance between the bottom 172 of the first button 170 and the upper surface 63 of the first lever body 60 gradually decreases. The first button 170 drives the link 50 to increase the included angle and the spring 53 is extended accordingly. The first coupling rod 51 is driven by the first button 170 to extend the flushing tube 110 toward the outside of the grip 150 (toward the distal end 150b). It should be understood that when the first button 170 continues to move to the first operation position, the first button 170 170 The distance between the bottom 172 of the 170 and the upper surface 63 of the first rod 60 is smaller (for example, the two may be slightly separated or contact the upper surface without exerting force on the first rod), and the included angle is larger At this time, the suction pipe 110 is extended longer toward the outside of the grip 150.

As shown in FIG. 7C, when the first button 170 is moved to the second operation position, the bottom 172 of the first button 170 contacts the first end 61 and pushes the first lever 60 below the original horizontal height of the upper surface 63. The first button 170 drives the link 50 to increase the included angle and the spring 53 is further extended accordingly. The first coupling rod 51 is driven by the first button 170 to extend the suction tube 110 outside the grip 150 (toward the distal end 150b). At this time, the length of the suction tube 110 beyond the grip 150 is longer than that of FIG. 7B (and the first When the button is moved to the first operation position). On the other hand, the second end 62 of the first rod body 60 is driven away from the pipe 160 by the first button 170, so that the pipe 160 is conducted. In this way, the suction pipe 110 can be connected to the interface through the pipe 160 to start the suction function (or the flushing function) of the suction pipe 110.

Conversely, when the first button 170 is moved from the second operation position to the first operation position, the suction pipe 110 is reduced in its extended length from the state shown in FIG. 7C. Specifically, the first button 170 is partially released, so that the included angle of the connecting rod 50 is reduced, and the spring 53 between the first connecting rod 51 and the second connecting rod 52 is shortened to drive the first connecting rod 51 to flush the suction tube. 110 retracts toward the grip 150. Therefore, the length of the flushing pipe 110 protruding beyond the grip 150 is reduced. On the other hand, as the first button 170 is released back to the first operation position, the upper surface 63 of the first rod body 60 returns to the original horizontal height, so the second end 62 of the first rod body 60 returns to the state of clamping the pipe 160 , So that the pipeline 160 is not conductive.

FIG. 8A is a schematic diagram of another embodiment of an endoscope device 10 according to the present invention. As shown in FIG. 8A, the endoscope device 10 includes a second button 175, which is disposed on the grip 150, and may be disposed near the first button 170, for example. In addition, the suction pipe 110 is connected to the first branch pipe 161 (refer to FIG. 8B) and the second branch pipe 162 in a direction extending away from the pipe member 130. In other words, the end of the flushing tube 110 extends inside the cavity and has a collecting port 112 (that is, the flushing tube faces away from the pipe 130 In the direction of extension, there is a manifold 112). Please refer to FIG. 8B for a top view. As shown in FIG. 8B, the manifold 112 is connected to the first branch pipe 161 and the second branch pipe 162. In this embodiment, the first branch pipe 161 and the second branch pipe 162 are arranged in parallel. One end of the first branch pipe 161 is connected to the suction interface 12, and one end of the second branch pipe 162 is connected to the flushing interface 14. As shown in FIG. 8B, an end portion 161a of the first branch pipe 161 is connected to the bus port, and an end portion 161b of the first branch pipe 161 opposite to the bus port is connected to the suction port 12 of the base of the grip 150. An end portion 162 a of the second branch pipe 162 is connected to the bus port, and an end portion 162 b of the second branch pipe 162 opposite to the bus port is connected to the flushing port 14 of the base of the grip 150.

Similar to the manner in which the first rod controls the conduction of the pipe, in this embodiment, the first button controls the conduction state of the first branch pipe, and the second button controls the conduction state of the second branch pipe. Specifically, the endoscope device 10 includes a first rod body 60 and a second rod body 65 provided in the cavity. The first end of the first rod body 60 is closer to the first button 170 than the second end, and the second end clamps the first branch pipe 161. The first end of the second rod body 65 is closer to the second button 175 than the second end, and the second end clamps the second branch pipe 162.

9A and 9B are schematic diagrams illustrating operations of the endoscope device 10 corresponding to FIG. 8A. The second button 175 is movable between a rest position and a third operation position. As shown in FIG. 9A, when the second button 175 is in the rest position, the bottom 177 of the second button 175 is substantially separated from the first end 66 of the second lever body 65. In other words, the bottom 177 of the second button 175 is close to the upper surface 68 of the second lever body 65 but the two remain slightly separated. In other embodiments, when the second button 175 is in the rest position, the bottom portion 177 of the second button 175 may contact the upper surface 68 without exerting force on the second rod body 65. At this time, the second end 67 of the second rod body 65 clamps the second branch pipe 162, so the second branch pipe 162 is not conductive. It should be added that the so-called rest position here refers to the natural position when the second button is not pressed, and the second button is substantially separated from the second lever body at this time. The third operation position refers to a position lower than the horizontal height of the upper surface of the second rod body.

As shown in FIG. 9B, when the second button 175 is moved to the third operation position, the bottom 177 of the second button 175 contacts the first end 66 and pushes the second lever body 65 below the original horizontal height of the upper surface 68. On the other hand, the second end 67 of the second rod body 65 is driven away from the second branch pipe 162 by the second button 175, so that the second branch pipe 162 is conducted. In this way, the flushing tube can be connected to the flushing interface 14 through the second branching tube 162 to start the flushing function of the flushing tube. In addition, the first button can operate the first lever body in a similar manner to connect the first branch pipe to the suction interface, and start the suction function of the flushing pipe. The specific operation mode has been described in FIG. 7A to FIG. 7C, and will not be repeated here.

FIG. 10A and FIG. 10B are schematic diagrams of an embodiment of the endoscope device 10 having a third branch pipe 163. The difference from the foregoing embodiment is that the endoscope device 10 includes a third branch pipe 163. The third branch pipe 163 is provided in parallel with the first branch pipe 161 and the second branch pipe 162. In this embodiment, one end of the third branch pipe 163 is connected to the instrument interface 16. As shown in FIG. 10A, an end portion 163 a of the third branch pipe 163 is connected to the bus port 112, and an end portion 163 b of the third branch pipe 163 opposite to the bus port 112 is connected to the instrument interface 16 of the base of the grip 150. When neither the first button 170 nor the second button 175 is activated, other examinations and treatments can be performed by using the instrument interface 16. For example, a user may extend into the surgical instrument through the instrument interface 16 and extend from one side of the tube member 130 remote from the distal end. As shown in FIG. 10B, the instrument 70 extends from the tube 130, wherein the instrument is, for example, a grasping, cutting, or electric burning tool, so that the affected part can be treated.

The present invention has been described by the above related embodiments, but the above embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the invention. On the contrary, modifications and equal settings included in the spirit and scope of the scope of patent application are all included in the scope of the present invention.
