Detailed Description

The present invention will be described in detail with reference to the drawings and embodiments, and it should be noted that in the following description, like elements are denoted by the same reference numerals.

Referring to fig. 1 to 3, a first embodiment of the endoscope apparatus of the present invention comprises a housing unit 1 adapted to be held by a user, a rotation unit 2 provided in the housing unit 1, an elastic unit 3 provided between the housing unit 1 and the rotation unit 2, an operation unit 4 connected to the rotation unit 2 and adapted to be operated by the user, a pipe member unit 5 connected to the housing unit 1, and a control unit 6 penetrating between the housing unit 1 and the pipe member unit 5 and connected between the rotation unit 2 and the pipe member unit 5.

Referring to fig. 2 to 4, the housing unit 1 includes a first housing group 11 having a grip shape adapted to be held by the user, and a second housing group 12 assembled to the first housing group 11.

The first shell group 11 includes two first half shells 111 (see fig. 2) located below and butted against each other, and an outer handle shell 112 located above and sleeved outside the second shell group 12. The first half shell 111 and the outer handle shell 112 are joined together up and down to cooperate to form the grip shape as described above, so as to be held by a user.

The second shell group 12 is located in the outer handle shell 112 and is formed by two second half shells 121 butt-jointed together. Each second half-shell 121 has a supporting portion 122 in the shape of a semi-circle at the center in the radial direction, a half-shell portion 123 in the shape of a semi-ring at the outside of the supporting portion 122 in the radial direction, and a plurality of curved rib portions 124 spaced from each other and connected to the upper portion inside the half-shell portion 123 by bending upward from the supporting portion 122.

The supporting portion 122 of the second half-shell 121 cooperatively supports the bottom of the elastic unit 3 and cooperatively forms a bottom protrusion 125 (see fig. 4) having a round block shape and inserted into the bottom end of the elastic unit 3.

The curved rib portion 124 of the second half-shell 121 extends in a curved manner to substantially conform to the shape of a sphere, thereby cooperatively defining a substantially spherical rotation space S11 (see fig. 4). The curved rib portions 124 further define a routing space S12, which is located between the two curved rib portions 124 and penetrates up and down, in a group.

Referring to fig. 2, 4 and 5, the rotating unit 2 includes a rotating member 21 disposed in the rotating space S11 defined by the second housing set 12, a plug member 22 inserted into the rotating member 21 from bottom to top, and a cover member 23 disposed on the top end of the rotating member 21.

The rotating member 21 includes a ring portion 24 as a lower half portion of the rotating member 21, a plurality of rib portions 25 having bottom ends extending upward from the ring portion 24 in an arc-shaped and spaced-apart arrangement and top ends connected to each other, and a bump portion 26 extending downward from a portion where the rib portions 25 are connected to each other and having a substantially round block shape.

The annular portion 24 is disposed on the curved rib portion 124 of the second case group 12 such that the rotating member 21 is cooperatively supported by the curved rib portion 124 and includes an inner wall section 241 (see fig. 4) extending upward and downward, and an outer wall section 242 extending upward and downward and located outside the inner wall section 241 in the radial direction.

The top end of the inner wall section 241 is connected to the outer wall section 242, and the bottom end is spaced from the outer wall section 242. The length of the inner wall section 241 extending up and down is smaller than the length of the outer wall section 242 extending up and down, and the inner wall section 241 is configured to be approximately inverted hook-shaped in cross section as shown in fig. 4.

An outer annular surface 244 of the outer wall section 242 is generally a portion of a sphere so that the annular portion 24 can slide relative to the curved rib portion 124. The outer annular surface 244 is formed with a plurality of routing grooves 245 extending up and down. The routing grooves 245 are spaced apart from each other in an arc direction and are respectively located above the routing spaces S12 of the second case set 12.

The rib portions 25 cooperate with the annular portion 24 in a group to define a plurality of routing channels S21 (see fig. 2 for illustration) extending transversely therethrough. Each routing channel S21 is connected between the inner space of the rotating member 21 and the outer space of the rotating member 21, and each routing channel S21 is also connected with the rotating space S112 because the rotating member 21 is disposed in the rotating space S11.

Each rib 25 is a part of a sphere or extends in a manner conforming to the outer shape of the sphere, so that the rib 25 cooperates with the annular portion 24 to make the whole outer shape of the rotary member 21 spherical, thereby allowing the rotary member 21 to freely rotate in three dimensions in the rotation space S11 with its own center as the rotation center. The ribs 25 cooperate to form a connection 251 (see fig. 4).

The boss portion 26 protrudes downward from the connection portion 251 of the bent rib portion 25 (see fig. 4).

The stopper 22 is located above the supporting portion 122 of the second case group 12 at intervals, and includes a bottom stopper portion 221 abutting against the bottom end of the inner wall section 241 of the annular portion 24 of the rotary member 21, and a top stopper portion 222 extending upward from the bottom stopper portion 221.

The top surface of the bottom plug 221 abuts against the bottom end of the inner wall section 241, and the bottom surface is concave from bottom to top and is formed with a top protrusion 223 having a round block shape and inserted into the top end portion of the elastic unit 3. The top plug 222 is plugged into the inner wall section 241 and is inserted over the lug 26 of the rotor 21.

The elastic unit 3 is a compression spring, and the top end and the bottom end are respectively positioned on the plug 22 and the supporting portion 122 of the second shell set 12, and are sleeved outside the top protrusion 223 of the plug 22 and the bottom protrusion 125 of the second shell set 12. The elastic unit 3 can elastically support the plug 22 upwards, so that the plug 22 abuts against the bottom end of the inner wall section 241 of the annular portion 24 and is limited in the annular portion 24 of the rotating member 21, thereby stably penetrating the protruding block portion 26 of the rotating member 21. Since the elastic unit 3 is positioned on the plug 22 and the second case group 12, the elastic unit 3 can be deformed by stretching to store the elastic force for resetting the plug 22 and the rotating member 21 when the plug 22 and the rotating member 21 are displaced relative to the second case group 12.

The cover member 23 is ring-shaped and covers the bent rib 25 of the rotating member 21, so as to protect the internal components and cooperate with the outer handle shell 112 of the housing unit 1 to make the overall appearance more compact and beautiful.

The operation unit 4 includes a rod body 41 screwed in a connection portion 251 of the cover 23 and the bent rib 25 of the rotation member 21, and a rod head 42 protruding from the housing unit 1 and adapted for the user to press.

Referring to fig. 3, 4 and 5, the pipe unit 5 includes a connector 51 assembled to the bottom of the housing unit 1, and a hose 52 inserted into the connector 51.

The connector 51 includes a connection end 511 assembled to communicate with the bottom of the first case group 11 of the case unit 1. The hose 52 includes a front tube portion 521 adapted to extend into the human body. The forefront of the front pipe 521 is adapted to be provided with a miniature camera device 7 for taking pictures or photographs to record the internal condition of the human body.

The control unit 6 comprises several control lines 61. One part of each control line 61 is connected to the boss 26 of the rotary member 21 of the rotary unit 2 as shown in fig. 5, and the other part is connected to the front end pipe 521 of the pipe unit 5.

Specifically, the portion of each control wire 61 is bent into a U-shape as shown in FIG. 5 so as to fit over the boss 26 as shown in FIG. 4. Next, each control wire 61 extends from a corresponding one of the routing channels S21 to the outside of the rotating member 21 (see fig. 2 for illustration) and into the rotating space S11 as shown in fig. 4, and then extends into a corresponding one of the routing spaces S12 of the second shell group 12 along one of the routing grooves 245 of the rotating member 21 so as to pass through the second shell group 12 of the housing unit 1 and extend into the first half shell 111 of the first shell group 11 as shown in fig. 3. Finally, the first shell 11 extends into the connecting end 511 of the connector 51, extends into the hose 52, and is positioned and arranged at the front end pipe 521.

Referring to fig. 3, 4 and 6, when the first embodiment is used, a user only needs to hold the first housing set 11 with one hand and pull the club head 42 of the operation unit 4 with a thumb, so as to drive the rotation member 21 to rotate through the club head 41 of the operation unit 4, and when the rotation member 21 rotates, one or more of the control wires 61 can be pulled and the other one or more of the control wires 61 can be released.

For example, with respect to fig. 3, when the user pulls the club head 42 to the right in the drawing of fig. 6 as shown in fig. 6, the control line 61 to the left in the drawing of fig. 6 can be pulled up, and the control line 61 to the right in the drawing of fig. 6 can be pulled down, so that the front end pipe 521 of the hose 52 is tilted up as shown in fig. 6, the front end pipe 521 is oriented differently from fig. 3, and the miniature imaging device 7 can be imaged at a position different from fig. 3.

Based on the foregoing operation manner, the first feature of the first embodiment is that the user holds the first embodiment with one hand, and operates the operation unit 4 with the thumb to drive the rotation member 21 to freely rotate in three dimensions, so as to control the direction of the front end pipe 521, so that the user, such as a doctor, can conveniently observe each part in the patient, and can actually grasp the focus position or confirm the health condition in the patient.

The second feature of the first embodiment is that the elastic unit 3 is assembled between the second housing set 12 and the rotating unit 2, so that, as shown in fig. 6, when the user releases the operating unit 4, the first embodiment can automatically return to the state shown in fig. 3. In addition, the elastic unit 3 can provide proper resistance when the user operates, so that the user is prevented from operating the head with force.

Referring to fig. 7 to 9, a second embodiment of the endoscope device of the present invention is similar to the first embodiment, except that:

the housing unit 1 omits the outer handle case 112 (see fig. 2), and the first half case 111 is different in structure from the second half case 121. A window 113 (see fig. 7) extending up and down is hollowed out in the middle portion of each first half shell 111. The supporting portion 122 of the second half-shell 121 and the curved rib portion 124 have different shapes, and cooperate to define two rod-receiving spaces S13 spaced apart from each other.

Referring to fig. 7, 8, and 10, the rotating unit 2 omits the stopper 22 (see fig. 2), and the rotating member 21 is different from the cover 23 in external shape. The rotor 21 cooperates with the cover 23 in a substantially hemispherical shape.

The control unit 6 includes, in addition to the aforementioned control line 61, a plurality of link mechanisms 62 extending downward from the rotating member 21 of the rotating unit 2. Two of the linkages 62 are in a group. One of the link mechanisms 62 and the other link mechanism 62 are spaced apart from each other approximately in a cross (see fig. 9), and one of the link mechanisms 62 and the other link mechanism 62 are different in length in the downward direction (described further below).

Each link mechanism 62 includes a first rod 63 inserted into the rotating member 21 of the rotating unit 2 and extending from top to bottom, a second rod 64 pivotally connected to the first rod 63 and extending transversely, and a connecting shaft 65 inserted between the first rod 63 and the rotating member 21.

Each first rod 63 includes a rod head 631 having a ball shape and inserted into the rotating member 21 and inserted into one end of a corresponding rod accommodating space S13 (see fig. 9), 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 coupled to the rotating member 21 through the spherical rod head 631, and can swing back and forth and left and right with respect to the rotating member 21.

Each second rod 64 includes a pivot rod 640 pivoted to one of the first half shells 111 of the housing unit 1, and a first rod 641 and a second rod 642 respectively located on opposite sides of the pivot rod 640.

Each pivot rod 640 is formed with a pivot shaft 643 inserted in a corresponding one of the first half shells 111. Each pivot 643 is located near a corresponding one of the first lever portions 641. In this way, the length of each first rod 641 is smaller than the length of a corresponding second rod 642.

Each of the first lever portions 641 is pivotally connected to the lever tail 633 of a corresponding one of the first levers 63, so that each of the second levers 64 can pivot up and down with respect to the corresponding one of the first levers 63. Each second rod portion 642 is hooked with a hook opening facing upwards opposite to a corresponding one of the first rod portions 641.

The length of two of the first bars 63 is greater than the other two of the first bars 63, so that the lengths of the downward extension of the link mechanisms 62 are different as described above, and so that the second bars 64 of two of them are lower than the second bars 64 of the other two.

Each control wire 61 is hooked on the second rod portion 642 of a corresponding one of the second rod members 64 and connected to the front end pipe portion 521 of the pipe unit 5. In other embodiments of the present invention, each control wire 61 can also be tied to a corresponding one of the second rods 642.

See fig. 7, 11, 12. In fig. 11, the operation unit 4 is pulled to tilt toward one of the link mechanisms 62 having a longer length, and drives the rotation unit 2 to rotate toward one of the link mechanisms 62 having a longer length. In fig. 12, the operation unit 4 and the rotation unit 2 are inclined and rotated toward one of the link mechanisms 62 having a shorter length

When the second embodiment is used, the user can pull the rod head 42 of the operation unit 4 with the thumb to drive the link mechanism 62 to act as shown in fig. 11 and 12, thereby tightening one or more of the control wires 61 and loosening the other one or more of the control wires 61.

Specifically, for example, in fig. 8 and 11, when the operation unit 4 and the rotation unit 2 are tilted and rotated by the link mechanism 62 having a longer length toward the right of the drawing, the first rod 63 of the link mechanism 62 on the right of the drawing is moved slightly downward, the first rod 63 of the link mechanism 62 on the left of the drawing is moved slightly upward, and the corresponding second rod 64 is laterally extended from the left and right of fig. 8 to be tilted upward to be raised upward to the left and right of fig. 11, so as to drive the front end pipe 521 of the hose 52 of the pipe unit 5 of the second embodiment, as shown in fig. 8 to be tilted upward to the left of fig. 11. The change from fig. 10 to fig. 12 is similar, except that in fig. 10 and 12, the link mechanism 62 with a shorter length drives the front end pipe 521 to operate.

One of the features of the present second embodiment is that the magnitude of tightening or loosening the control wire 61 is dependent on the magnitude of pivoting of the second lever 64 as compared with the magnitude of rotation of the rotating member 21 of the first embodiment.

That is, on the basis that the rotation angles of the rotation member 21 of the first embodiment and the rotation member 21 of the second embodiment are the same, the magnitude of the rotation member of the second embodiment capable of driving the front end pipe 521 to change direction is larger, so that the second embodiment has the characteristic of easier control of changing direction than the first embodiment, and the first embodiment has the characteristic of more accurate control because of smaller magnitude of changing direction.

Specifically, since the length of each first lever 641 is smaller than that of a corresponding one of the second levers 642, only a small rotation/movement range is required for the rotation unit 2 and the first lever 63, so that the second lever 642 can have a large swing range by the lever principle.

The second feature of the second embodiment is that by changing the position of each pivot rod 640 and/or the lengths of the corresponding first rod 641 and the corresponding second rod 642, the second embodiment can change the control sensitivity and even tailor the product according with the operation hand feeling of different operators (doctors).

The third feature of the second embodiment is that the length of the first rod 63 is different, so that the length of the downward extending of the link mechanism 62 is different, and the second rod 64 is vertically displaced, so that the second embodiment has the characteristics of compact structure and small overall volume.

In summary, the endoscope apparatus of the present invention provides an endoscope apparatus which is different from the conventional endoscope apparatus in terms of design and operation convenience, and can be used as an alternative to promote the development and benign competition of the medical industry and enhance the well-being of patients by allowing the user to conveniently control the direction of the front end pipe portion 521 by the rotating member 21 which can freely rotate in three dimensions of three dimensions with its own center as the rotation center, so as to achieve the purpose of the present invention.

The above description is only for the specific embodiments of the present invention, and the scope of the claims of the present invention should not be limited thereto, and the equivalents of the claims and descriptions of the present invention should be covered by the scope of the claims of the present invention.
