Description

Technical Field

[0001] This invention relates to a medical device, and more particularly to an endoscopic device suitable for examining the internal condition of the human body. Background Technology

[0002] Endoscopes refer to various instruments that can be inserted into the human body to examine the internal health conditions. Examples include gastroscopes (entered through the mouth and nose) and colonoscopes (entered through the anus). An endoscope typically consists of a tubular unit that extends into the body, a camera unit at the front of the tubular unit for imaging the internal condition, a control unit running through the tubular unit, and a controller at the other end of the tubular unit connected to the wired control unit.

[0003] The wired control unit includes several control lines connecting the front end of the tubular unit to the controller. The controller includes multiple knobs. Rotating the knobs changes the length of the control lines, which in turn changes the orientation of the front end of the tubular unit, thereby adjusting the orientation of the imaging unit to capture images of various parts of the human body. While this existing controller can be used to control endoscopes, there is a need for a controller with a different structure to provide more options and promote the development of the medical industry. Summary of the Invention

[0004] The purpose of this invention is to provide an endoscope device that can solve at least one problem of the prior art.

[0005] The present invention relates to an endoscope device comprising a housing unit suitable for a user to hold, a rotating unit disposed within the housing unit, a tubular unit connecting the housing unit, a control unit disposed within the housing unit and the tubular unit and connected between the rotating unit and the tubular unit, and an operating unit connected to the rotating unit and protruding from the housing unit for operation by the user. The tubular unit includes a front end suitable for insertion into the human body, and a connecting end opposite to the front end and communicating with the housing unit. The control unit is connected between the rotating unit and the front end. The rotating unit can be driven by the operating unit to rotate freely in three dimensions of three-dimensional space around its own center of rotation, thereby driving the control unit to drive the tubular unit and change the orientation of the front end of the tubular unit.

[0006] The endoscope device of the present invention includes a rotating unit comprising a rotating component disposed in the housing unit and connected to the operating unit. The rotating component includes an annular portion, a plurality of curved ribs extending upward from the annular portion and connected to each other at their top ends in an arc-shaped arrangement at their bottom ends, and a protrusion extending downward from the connecting portion of the curved ribs. The curved ribs cooperate with the annular portion to define a plurality of transversely extending wiring channels. The control unit includes a plurality of control lines, a portion of which is connected to the protrusion and extends through the corresponding wiring channel to the space between the rotating component and the housing unit, and another portion is connected to the front end tube of the tube unit.

[0007] The endoscope device of the present invention includes a housing unit comprising a first housing assembly suitable for the user to hold, and a second housing assembly disposed within the first housing assembly. The second housing assembly includes a plurality of spaced-apart curved ribs that cooperate to support the rotating member and define a rotation space for the rotating member to rotate, and also cooperate to define a plurality of wiring spaces communicating with the rotation space. Each control line extends into the rotation space via a corresponding wiring channel, and then extends into the first housing assembly via the corresponding wiring space, and then into the tubular unit.

[0008] In the endoscope device of the present invention, the outer surface of the annular portion is formed with a plurality of vertically extending wiring grooves, each wiring groove being located between the corresponding wiring channel and the corresponding wiring space.

[0009] The endoscope device of the present invention further includes a plug inserted in the annular portion and sleeved on the protrusion portion, wherein the plug cooperates with the connecting portion of the curved rib portion to limit the control line sleeved on the protrusion portion between the plug and the connecting portion.

[0010] The endoscope device of the present invention further includes a plurality of support portions located below the plug and connected to the bottom end of the curved rib portion in the second housing assembly. The endoscope device also includes an elastic unit assembled between the plug and the support portion. The elastic unit can elastically support the plug upward, so that the plug is positioned and fitted in the annular portion, and can be stretched and deformed when the rotating member of the rotating unit rotates relative to the housing unit, thereby storing the elastic force to reset the rotating member.

[0011] The endoscope device of the present invention further includes a cover on the rotating member and covering the curved rib, and an operating unit including a rod screwed in the connection between the cover and the curved rib, and a rod head protruding from the housing unit and adapted for the user to operate by pressing.

[0012] The endoscope device of the present invention includes a control unit comprising a plurality of linkage mechanisms extending downward from the rotating unit, and a plurality of control lines connecting the linkage mechanisms and the front end tube of the tube unit. Each linkage mechanism includes a first rod extending vertically and connected to the rotating unit, and a second rod extending laterally and pivotally connected to the first rod. Each first rod can be driven by the rotating unit to move vertically, and each second rod can be driven by the first rod to pivot vertically relative to the housing unit. The second rod includes a pivot rod portion pivotally connected to the housing unit, and a first rod portion and a second rod portion located on opposite sides of the pivot rod portion. Each first rod portion is pivotally connected to the corresponding first rod, and each second rod portion is connected to the corresponding control line.

[0013] In the endoscope device of the present invention, the linkage mechanisms are arranged at angular intervals, and the length of the first link of two of the linkage mechanisms is greater than the length of the first link of the other two linkage mechanisms, and the second link of two of the linkage mechanisms is shorter than the second link of the other two linkage mechanisms.

[0014] In the endoscope device of the present invention, the length of each first rod portion is less than the length of the corresponding second rod portion.

[0015] The endoscope device of the present invention includes each first rod member comprising a spherical rod head inserted into the rotating unit. Each rod head is rotatable relative to the rotating unit, thereby enabling each first rod member to swing back and forth and left and right relative to the rotating unit, thereby driving the corresponding second rod member. Each linkage mechanism further includes a connecting shaft inserted between the corresponding rod head and the rotating unit.

[0016] The beneficial effects of this invention are: it provides an endoscope device that differs from existing designs as an option, is quite convenient to operate, promotes the development of the medical industry and healthy competition, and enhances patient well-being.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and various embodiments. It should be noted that similar elements are represented by the same numbers in the following description.

[0030] See Figures 1 to 3A first embodiment of the endoscope device of the present invention includes a housing unit 1 suitable for a user to hold, a rotating unit 2 disposed in the housing unit 1, an elastic unit 3 disposed between the housing unit 1 and the rotating unit 2, an operating unit 4 connected to the rotating unit 2 and suitable for operation by the user, a tube unit 5 connected to the housing unit 1, and a control unit 6 passing through the housing unit 1 and the tube unit 5 and connected between the rotating unit 2 and the tube unit 5.

[0031] See Figures 2 to 4 The housing unit 1 includes a first housing assembly 11 shaped like a handle for the user to hold, and a second housing assembly 12 assembled on the first housing assembly 11.

[0032] The first shell assembly 11 includes two lower, mating first half-shells 111 (see...) Figure 2 The first half-shell 111 and the outer handle shell 112 are located above and fit over the second shell assembly 12. The first half-shell 111 and the outer handle shell 112 are joined together to form the grip shape described above, so that a user can hold and use it.

[0033] The second shell assembly 12 is located within the outer shell 112 and is formed by two second half-shells 121 joined together. Each second half-shell 121 has a support portion 122 located centrally in the radial direction and generally in the shape of a semi-circular block, a half-shell portion 123 in the radial direction that is semi-annular and located outside the support portion 122, and a plurality of spaced-apart curved ribs 124 that extend upward from the support portion 122 and connect to the upper inner part of the half-shell portion 123.

[0034] The support portion 122 of the second half-shell 121 cooperates to support the bottom of the elastic unit 3, and cooperates to form a bottom protrusion 125 in the shape of a round block inserted into the bottom end of the elastic unit 3 (see...). Figure 4 ).

[0035] The curved rib 124 of the second half-shell 121 extends in a manner that generally conforms to the shape of a sphere, thus defining a roughly spherical rotational space S11 (see...). Figure 4 The curved ribs 124 also define a wiring space S12 that is located between the two curved ribs 124 and runs vertically through them.

[0036] See Figure 2 , 45. The rotating unit 2 includes a rotating component 21 disposed in the rotating space S11 defined by the second shell assembly 12, a plug 22 inserted into the rotating component 21 from bottom to top, and a cover 23 covering the top of the rotating component 21.

[0037] The rotating member 21 includes an annular portion 24 that is the lower half of the rotating member 21, a plurality of curved ribs 25 that are arranged at intervals at their bottom ends and extend upward from the annular portion 24 and are connected to each other at their top ends, and a protruding portion 26 that extends downward from the portion where the curved ribs 25 are connected to each other and is generally in the shape of a circular block.

[0038] The annular portion 24 is disposed on the curved rib portion 124 of the second shell assembly 12, so that the rotating member 21 is supported by the curved rib portion 124, and includes an inner wall section 241 extending vertically (see Figure 4 ), and an outer wall segment 242 that extends vertically and is located radially outside the inner wall segment 241.

[0039] The top end of the inner wall segment 241 connects to the outer wall segment 242, while the bottom end is spaced apart from the outer wall segment 242. The vertical length of the inner wall segment 241 is less than the vertical length of the outer wall segment 242, and it forms a cross-section that matches the outer wall segment 242. Figure 4 The shape shown is roughly hook-shaped.

[0040] The outer annular surface 244 of the outer wall segment 242 is generally part of a sphere, so the annular portion 24 can slide relative to the curved rib portion 124. The outer annular surface 244 is formed with a plurality of vertically extending wiring grooves 245. The wiring grooves 245 are spaced apart from each other in an arc direction and are respectively located above the wiring space S12 of the second shell assembly 12.

[0041] The two bent ribs 25, in combination with the annular portion 24, define multiple laterally extending and continuous wiring channels S21 (see...). Figure 2 (Illustrative). Each wiring channel S21 connects the internal space of the rotating member 21 with the external space of the rotating member 21. Since the rotating member 21 is located in the rotating space S11, each wiring channel S21 also connects to the rotating space S112.

[0042] Each curved rib 25 is generally a part of a sphere, or its extension conforms to the shape of a sphere. Therefore, the curved rib 25 cooperates with the annular portion 24 to make the overall shape of the rotating member 21 generally spherical, thereby allowing the rotating member 21 to rotate freely in three dimensions in the rotation space S11 with its own center of rotation as the rotation center. The curved ribs 25 cooperate to form a connecting part 251 (see...). Figure 4 ).

[0043] The protrusion 26 extends downward from the connecting portion 251 of the bent rib 25 (see...). Figure 4 ).

[0044] The plug 22 is located at intervals above the support portion 122 of the second shell assembly 12, and includes a bottom plug portion 221 that abuts against the bottom end of the inner wall section 241 of the annular portion 24 of the rotating member 21, and a top plug portion 222 that extends upward from the bottom plug portion 221.

[0045] The top surface of the bottom plug 221 abuts against the bottom end of the inner wall section 241. The bottom surface is concave from bottom to top and forms a round block 223 that is inserted into the top part of the elastic unit 3. The top plug 222 is inserted into the inner wall section 241 and passes through the outside of the protrusion 26 of the rotating member 21.

[0046] The elastic unit 3 is a compression spring, with its top and bottom ends positioned on the support portion 122 of the plug 22 and the second shell assembly 12, respectively, and passing through the top protrusion 223 of the plug 22 and the bottom protrusion 125 of the second shell assembly 12. The elastic unit 3 can elastically support the plug 22 upwards, causing the plug 22 to abut against the bottom end of the inner wall section 241 of the annular portion 24 and be confined within the annular portion 24 of the rotating member 21, thereby stably passing through the protrusion portion 26 of the rotating member 21. Since the elastic unit 3 is positioned on the plug 22 and the second shell assembly 12, when the plug 22 and the rotating member 21 are displaced relative to the second shell assembly 12, the elastic unit 3 can be stretched and deformed to store the elastic force for the plug 22 and the rotating member 21 to return to their original position.

[0047] The cover 23 is generally ring-shaped and covers the curved rib 25 of the rotating member 21. It can protect the internal components and cooperate with the outer handle shell 112 of the housing unit 1 to make the overall shape simpler and more beautiful.

[0048] The operating unit 4 includes a rod 41 screwed into the connection 251 of the curved rib 25 of the cover 23 and the rotating member 21, and a rod head 42 protruding from the housing unit 1 and adapted for the user to operate by pressing.

[0049] See Figure 3 , 4 5. The fitting unit 5 includes a connector 51 for assembling the bottom of the housing unit 1, and a flexible hose 52 inserted into the connector 51.

[0050] The connector 51 includes a connecting end 511 that is assembled and connected to the bottom of the first shell assembly 11 of the housing unit 1. The hose 52 includes a front end tube 521 suitable for insertion into a human body. The foremost end of the front end tube 521 is adapted to be fitted with a miniature camera device 7 to take pictures or videos to record the internal condition of the human body.

[0051] The control unit 6 includes a plurality of control lines 61. A portion of each control line 61 is as follows: Figure 5 The protrusion 26 of the rotating member 21 of the rotating unit 2 is shown to be connected to the rotating unit 2, and another part is connected to the front end tube 521 of the tube unit 5.

[0052] Specifically, one part of each control line 61 is as follows: Figure 5 As shown, it is bent into a U-shape, thus... Figure 4 The control line 61 is shown to be fitted onto the protrusion 26. Then, each control line 61 extends from a corresponding wiring channel S21 to the outside of the rotating member 21 (see...). Figure 2 (Illustration) and as Figure 4 As shown, it enters the rotation space S11, and then extends along one of the wiring grooves 245 of the rotating member 21 into a wiring space S12 corresponding to the second housing assembly 12, thereby passing through the second housing assembly 12 of the housing unit 1 and as shown. Figure 3 It extends into the first half-shell 111 of the first shell assembly 11 as shown. Finally, it extends through the first shell assembly 11 into the connecting end 511 of the connector 51, and into the hose 52, and is finally positioned at the front end tube 521.

[0053] See Figure 3 , 4 6. In the first embodiment, when the user uses the first housing assembly 11, he / she only needs to hold the first housing assembly 11 with one hand and turn the lever head 42 of the operation unit 4 with his / her thumb. The lever body 41 of the operation unit 4 will drive the rotating member 21 to rotate. When the rotating member 21 rotates, one or more of the control lines 61 will be tightened and the other one or more of the control lines 61 will be loosened.

[0054] Compared to Figure 3 For example, when the user places the rod head 42 as... Figure 6 As shown Figure 6 Flipping the slider to the right of the image will... Figure 6 Pull the control line 61 on the left side of the middle image upwards, and... Figure 6 The control line 61 on the right side of the middle image is lowered, so that the front end section 521 of the hose 52 is as shown. Figure 6As shown, it curves upwards, and the orientation of the front end tube 521 is different. Figure 3 This enables the miniature camera device 7 to capture images different from those obtained through other means. Figure 3 The part.

[0055] Based on the aforementioned operating method, the first feature of this first embodiment is that the user can hold this first embodiment with one hand and use the thumb to operate the operating unit 4 to drive the rotating part 21 to rotate freely in three dimensions, thereby controlling the orientation of the front tube 521. Therefore, the user, such as a doctor, can easily observe various parts of the patient's body, accurately grasp the location of the lesion, or confirm the patient's health status.

[0056] The second feature of this first embodiment is that the elastic unit 3 is assembled between the second shell assembly 12 and the rotating unit 2, so that... Figure 6 For example, when the user releases the operation unit 4, this first embodiment can automatically return to the state shown above. Figure 3 The state shown is as described. In addition, the elastic unit 3 can also provide appropriate resistance when the user operates it, so as to prevent the user from over-operating when applying force.

[0057] See Figures 7 to 9 A second embodiment of the endoscope device of the present invention is similar to the first embodiment, except that:

[0058] The housing unit 1 omits the outer handle shell 112 (see...). Figure 2 Furthermore, the structures of the first half-shell 111 and the second half-shell 121 are different. Each first half-shell 111 has a vertically extending window 113 cut out in the middle portion (see...). Figure 7 The support portion 122 of the second half-shell 121 has a different shape from the curved rib portion 124, and they cooperate to define two spaced rod spaces S13.

[0059] See Figure 7 , 8 10. The rotating unit 2 omits the plug 22 (see...) Figure 2 Furthermore, the rotating component 21 and the cover component 23 have different shapes. The rotating component 21 and the cover component 23 are generally hemispherical when they are fitted together.

[0060] In addition to the aforementioned control line 61, the control unit 6 further includes a plurality of linkage mechanisms 62 extending downward from the rotating member 21 of the rotating unit 2. The linkage mechanisms 62 are grouped in pairs. The connecting rod mechanism 62 of one group and the linkage mechanism 62 of the other group are generally cross-shaped intervals (see...). Figure 9Furthermore, the lengths of the downward extension of one set of linkage mechanism 62 and the other set of linkage mechanism 62 are different (to be explained further later).

[0061] Each of the linkage mechanisms 62 includes a first rod 63 that is inserted into the rotating member 21 of the rotating unit 2 and extends downward, a second rod 64 that is pivotally connected to the first rod 63 and extends laterally, and a connecting shaft 65 that is inserted between the first rod 63 and the rotating member 21.

[0062] Each first rod 63 includes a spherical member that is inserted into the rotating member 21 and inserted into a corresponding rod space S13 (see Figure 9 The first rod 63 has a rod head 631 at one end, a rod body 632 extending downward from the rod head 631, and a rod tail 633 pivotally connected to the second rod 64. Each first rod 63 is connected to the rotating member 21 via the spherical rod head 631, and can swing back and forth and left and right relative to the rotating member 21.

[0063] Each second member 64 includes a pivoting rod portion 640 pivotally connected to one of the first half-shells 111 of the housing unit 1, and a first rod portion 641 and a second rod portion 642 located on opposite sides of the pivoting rod portion 640.

[0064] Each pivot member 640 has a pivot shaft 643 inserted into a corresponding first half-shell 111. Each pivot shaft 643 is positioned close to a corresponding first member 641. In this way, the length of each first member 641 is less than the length of a corresponding second member 642.

[0065] Each of the first rod portions 641 is pivotally connected to the tail portion 633 of a corresponding first rod 63, such that each second rod 64 can pivot up and down relative to a corresponding first rod 63. The portion of each second rod portion 642 opposite to that of its corresponding first rod portion 641 is hook-shaped with the hook facing upwards.

[0066] The lengths of two of the first links 63 are greater than those of the other two, such that the lengths of the linkage 62 extending downward are different as previously described, and that the second links 64 of two of them are lower than the second links 64 of the other two.

[0067] Each control line 61 is hooked onto the second rod portion 642 of a corresponding second rod 64 and connected to the front end tube portion 521 of the tube unit 5. In other embodiments of the invention, each control line 61 may also be tied to a corresponding second rod portion 642.

[0068] See Figure 7 , 11 12. In Figure 11 In this process, the operating unit 4 is moved to tilt towards one of the longer segments of the linkage mechanism 62, thereby causing the rotating unit 2 to rotate towards the longer segment of the linkage mechanism 62. Figure 12 In this process, the operating unit 4 and the rotating unit 2 respectively tilt and rotate towards the shorter of the linkage mechanism 62.

[0069] In this second embodiment, the user can also simply use their thumb to move the lever head 42 of the operation unit 4 to achieve the same result. Figure 11 , 12 The linkage mechanism 62 is activated as shown, thereby tightening one or more of the control lines 61 and loosening the other one or more of the control lines 61.

[0070] Specifically Figure 8 , 11 For example, when the operating unit 4 and the rotating unit 2 tilt and rotate towards the longer linkage mechanism 62 on the right side of the figure, the first link 63 of the linkage mechanism 62 on the right side of the figure can be moved slightly downward, and the first link 63 of the linkage mechanism 62 on the left side of the figure can be moved slightly upward, while the corresponding second link 64 is moved from... Figure 8 The area shown is generally extended horizontally to the left and right, and transformed into... Figure 11 As shown, it extends at an angle, higher on the upper left and lower on the lower right, thereby driving the front end portion 521 of the flexible hose 52 of the pipe unit 5 in this second embodiment, as... Figure 8 Change to Figure 11 The ground curves upwards and to the left of the image as shown. Figure 10 Transformation to Figure 12 The changes are similar, the difference being that... Figure 10 and Figure 12 In this process, the shorter linkage mechanism 62 drives the front end tube 521 to actuate.

[0071] One of the features of this second embodiment is that, compared to the first embodiment where the tightening or loosening of the control line 61 depends on the rotation amplitude of the rotating member 21 in the first embodiment, the tightening or loosening of the control line 61 in this second embodiment depends on the pivot amplitude of the second rod 64.

[0072] In other words, while the rotating member 21 in the first embodiment and the rotating member 21 in the second embodiment rotate at the same angle, the second embodiment can drive the front end tube 521 to change direction by a greater extent. Therefore, the second embodiment is easier to control and change direction compared to the first embodiment, while the first embodiment has more precise control because the range of direction change is smaller.

[0073] Specifically, since the length of each first rod 641 is less than the length of the corresponding second rod 642, the rotating unit 2 and the first rod 63 only need a small rotation / movement amplitude to enable the second rod 642 to have a large swing amplitude through the lever principle.

[0074] The second feature of this second embodiment is that by changing the position of each pivot rod 640, or changing the length of the corresponding first rod 641 and the corresponding second rod 642, this second embodiment can change the control sensitivity, and can even tailor a product to suit the operating feel of different operators (doctors).

[0075] The third feature of this second embodiment is that, by using the different lengths of the first rod 63, the lengths of the connecting rod mechanism 62 extending downwards are different, and the second rod 64 is misaligned vertically. This second embodiment has the characteristics of a relatively compact structure and a small overall volume.

[0076] In summary, the endoscope device of the present invention, by means of the rotating member 21 which can rotate freely in three dimensions of three-dimensional space with its own center of rotation as the rotation center, allows the user to conveniently control the direction of the front end tube 521. It provides an endoscope device that is different from the existing design and is easy to operate, which can be used as an option, promotes the development of the medical industry and healthy competition, and improves the well-being of patients. Therefore, it can indeed achieve the purpose of the present invention.

The endoscope device as described in claim 1, characterized in that: The housing unit includes a first housing assembly suitable for the user to hold, and a second housing assembly disposed within the first housing assembly. The second housing assembly includes a plurality of spaced-apart curved ribs that cooperate to support the rotating member and define a rotation space for the rotating member to rotate, and also cooperate to define a plurality of wiring spaces communicating with the rotation space. Each control line extends into the rotation space via a corresponding wiring channel, and then extends into the first housing assembly via the corresponding wiring space, and then into the tubular unit.

3. The endoscope device as described in claim 2, characterized in that: The outer surface of the annular portion is formed with a plurality of vertically extending wiring grooves, each wiring groove being located between the corresponding wiring channel and the corresponding wiring space.

4. The endoscope device as described in claim 2, characterized in that: The rotating unit further includes a plug inserted into the annular portion and sleeved on the protrusion portion. The plug cooperates with the connecting portion of the curved rib to limit the control line sleeved on the protrusion portion between the plug and the connecting portion.

5. The endoscope device as described in claim 4, characterized in that: The second housing assembly also includes a plurality of support portions located below the plug and connected to the bottom end of the curved rib. The endoscope device also includes an elastic unit assembled between the plug and the support portion. The elastic unit can elastically support the plug upward, so that the plug is positioned and inserted in the annular portion, and can be stretched and deformed when the rotating member of the rotating unit rotates relative to the housing unit, thereby storing the elastic force that resets the rotating member.

6. The endoscope device as claimed in claim 1, characterized in that: The rotating unit further includes a cover that covers the rotating part and conceals the curved rib. The operating unit includes a rod screwed into the connection between the cover and the curved rib, and a rod head that protrudes from the housing unit and is suitable for the user to operate by pressing.
