Referring to fig. 4, the reusable segment 10 further includes: the transmission part at least comprises a first transmission rod 101 and a second transmission rod 102, and the near ends of the first transmission rod 101 and the second transmission rod 102 are connected with the driving unit in a matching manner;
under the driving force of the driving unit, one of the first driving rod 101 and the second driving rod 102 moves in a preset direction, and the other of the first driving rod 101 and the second driving rod 102 moves in the opposite direction of the preset direction.
Further, the air conditioner is provided with a fan,
referring to fig. 4, in an embodiment of the present invention, the driving unit includes:
a first gear pair, which includes a first driving gear 120 and a first driven gear 13, wherein the first driving gear 120 is in driving connection with the operating unit 11, specifically, the operating unit 11 includes a shift lever or a shift wheel, and fig. 3 shows that the operating unit 11 is a shift wheel structure, a rotating shaft is arranged at the center of the shift wheel structure, and the rotating shaft is connected to the first driving gear 120, so that the first driving gear 120 is rotated in the process of operating the shift wheel, and the first driven gear 13 is driven; further, in the structure shown in fig. 4, the first driven gear 13 is connected to the proximal ends of the first transmission rod 101 and the second transmission rod 102.
With continued reference to fig. 4, one of the first driven gear 13 and the first transmission rod 101 is provided with a first sliding slot 132, and the other one of the first driven gear 13 and the first transmission rod 101 is provided with a first sliding block 1012 in fit connection with the first sliding slot 132;
and, any one of the first driven gear 13 and the second transmission rod 102 is provided with a second sliding slot 131, and the other one of the first driven gear 13 and the second transmission rod 102 is provided with a second sliding block 1022 in matching connection with the second sliding slot 131.
In order to ensure that the first transmission rod 101 and the second transmission rod 102 move in a predetermined direction, a first guide hole 163 and a second guide hole 160 surrounding the first transmission rod 101 and the second transmission rod 102 are fixedly provided on the mounting plate 16 in the housing.
In the embodiment shown in fig. 4, the first and second slide slots 132, 131 are both mounted on the first driven gear 13; and the first sliding slot 132 and the second sliding slot 131 are symmetrically arranged on both sides of the rotation center of the first driven gear 13. In this embodiment, the first transmission rod 101 and the second transmission rod 102 are respectively provided with a first slider 1012 and a second slider 1022 which are matched with the first sliding chute 132 and the second sliding chute 131; when the first driven gear 13 is forced to rotate, please refer to fig. 5, the mounting bolt 15 of the first driven gear 13 around its rotation center rotates counterclockwise to make the first transmission rod 101 and the second transmission rod 102 reach the position shown in fig. 5, it should be noted that, during the rotation process, the first sliding chute 132 and the second sliding chute 131 push the first sliding block 1012 and the second sliding block 1022 to move in opposite directions simultaneously, so that the first driving lever 101 and the second driving lever 102 make a linear motion on a predetermined action track, the first push rod 201 and the second push rod 202 located in the disposable section 20 of the endoscope handle are moved synchronously in the moving direction of the first transmission rod 101 and the second transmission rod 102 by the first transmission rod 101 and the second transmission rod 102, so as to move the first lead wire 2011 and the second lead wire 2021 connected to the first push rod 201 and the second push rod 202, respectively, thereby adjusting the active bending portion provided on the disposable segment 20; wherein the active bend bending angle on the disposable segment 20 is achieved by adjusting the turning angle of the thumb wheel.
It should be noted that, in the prior art, the bending angle of the active bending portion is realized by adjusting the shift lever or the shift wheel, and when the shift lever or the shift wheel rotates by a preset angle, the bending angle of the active bending portion is bent by a corresponding angle; therefore, when the bending angle of the bending portion needs to be adjusted to reach the limit bending angle, the rotation angle corresponding to the shift lever or the shift wheel is also large, and it should be noted that the endoscope handle usually needs to be operated by one hand during use. However, the adjustment of the wide angular range of the bending portion is difficult during one-handed operation. The reason is that when the hand holds the endoscope handle to keep stability, the finger needs to move to a larger range to toggle the shift lever or the shift wheel, which is difficult for different operation individuals, and in addition, the operator is difficult to judge the bending condition of the active bending part by hand feeling in the process of operating the shift wheel or the shift lever.
In order to solve the above problem, the present invention provides that the first sliding slot 132 and the second sliding slot 131 are both mounted on the first driven gear 13; and the first sliding chute 132 and the second sliding chute 131 are symmetrically arranged on both sides of the rotation center of the first driven gear 13. Referring to fig. 6, when the first driven gear 13 is driven counterclockwise to rotate from the position a to the position b, in the process, since the first transmission rod 101 and the second transmission rod 102 can only move in the predetermined direction indicated by the arrow, the height of the first slider 1012 and the second slider 1022 reaching the rotation center of the first driven gear 13 is H, and the height H does not change with the movement of the first transmission rod 101, the second transmission rod 102 and the first driven gear 13, so the lateral displacement of the first slider 1012 from the position a to the position b is L, which is in conjunction with the lateral displacement L of the first driven gear 13 and the first transmission rod 101, the second transmission rod 102 and the first driven gear 13The rotation angle θ of the driven gear 13 is correlated, and it can be concluded that H, L is in relation to θ as follows: l ═ H · tan θ; it can be obtained that the process of moving the first slider from the a position to the b position is related only to the rotation angle θ of the first driven gear 13; further, the rate of change of L with θ can be derived as follows: l ═ H/cos 2 θ, which increases from 0 due to the process of the first slider 1012 moving from the a position to the b position, L' is H/cos 2 Theta is gradually increased; therefore, when an operator dials the shift lever or the dial wheel, the moving amplitude of the first transmission rod 101 and the second transmission rod 102 in the preset direction is greater than the unit rotation angle of the first driven gear 13, so that the range of the operator needing to dial the shift lever or the dial wheel in the process of bending the active bending part to the limit position is reduced, and a larger bending angle can be obtained by dialing a smaller range; in the prior art, the engagement of a multi-stage gear set is needed to achieve the effect, however, only one gear is needed to solve the problem, the structure is simple, the scheme of abandoning the multi-stage gear can reduce the manufacturing cost of the endoscope handle, and the endoscope handle is more beneficial to patients; in addition, the layout space in the handle is extremely limited, more parts increase the structural layout difficulty of the inner space of the handle, and in addition, the appearance structure of the handle needs to accord with human engineering, so that the handle is convenient for an operator to use.
Meanwhile, as shown in fig. 7, in the process of rotating the first driven gear 13, when the first slider 1012 is located at the position a, the force applied to the first slider 1012 by the groove wall of the first sliding groove 132 is f, and after the position b is reached, if the force applied by the operator is still f, the force that the first sliding groove 132 pushes the first slider 1012 in the preset direction is f1, and in conjunction with the decomposition principle of the force shown in fig. 7, f1 is f · cos θ < f; therefore, it means that a larger driving force is required in the process of the operator moving the first slider 1012 from the a position to the b position while securing the same rotational speed; in other words, in the process of moving the first slider 1012 from the a position to the b position, the operator can obtain better driving feel when dialing the dial wheel or the dial; therefore, the bending condition of the active bending part can be judged by the force feedback of an operator, the operator can obtain better hand feeling in the operation process, and the operator can be quickly helped to adapt to the use of the endoscope handle.
In other embodiments of the present invention, the first sliding groove 132 and the second sliding groove 131 are symmetrical with respect to the rotation center of the first driven gear 13. Thereby causing the first driving lever 101 and the second driving lever 102 to obtain a synchronous displacement.
Referring to fig. 4 to 7, the first sliding groove 132 and the second sliding groove 131 have open notches at ends along the radial direction of the first driven gear 13. The open type gap may be beneficial for the installation of the first and second sliders 1012, 1022, thereby improving the assembly efficiency of the handle.
In another embodiment of the present invention, the ends of the first sliding groove 132 and the second sliding groove 131 in the radial direction of the first driven gear 13 may be a closed structure, which may prevent the first sliding block 1012 and the second sliding block 1022 from sliding away from the first sliding groove 132 and the second sliding groove 131 in the radial direction of the first driven gear 13.
In other embodiments of the present invention, the reusable section 10 may further include two sets of driving portions and two sets of transmission portions, and the two sets of driving portions respectively drive the two sets of transmission portions, so that the active bending portion can be deflected at four angles.
The present invention also provides an endoscope handle comprising a reusable section 10 of an endoscope handle as described above.
The invention also provides an endoscope comprising a reusable section 10 of an endoscope handle as described above, and an endoscope handle as described above.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
