[0029] Referring now to the drawings, and specifically to FIG. 1, an embodiment of the features of the disclosure will be discussed generally. FIG. 1 illustrates a side view of an exemplary endoscope system 100 with a handpiece 105 incorporating an endoscope install/release button 120 and an angle of view selector 110. Handpiece 105 may include both an angle of view selector 110 and an endoscope install/release button 120 or may include one or the other of angle of view selector 110 and endoscope install/release button 120.

[0030] As shown in FIG. 1, angle of view selector 110 may be implemented as a dial with tactile indicators, which will be discussed below. Angle of view selector 110 may be positioned on a topmost portion of the handpiece 105, although other implementations are possible such as on either side of handpiece 105 to facilitate left or right handed surgeons. Angle of view selector 110 may further include user interface elements 115, which may also facilitate a change of angle of view for a camera (not shown) or may provide user control over other functions of endoscope system 100 (e.g., turning a light source on and off, turning the device on and off, etc.). User interface elements 115 may be implemented as buttons, levers, or any other device for supplying user input into a handpiece known in the art.

[0031] Handpiece 105 may further include a depressible button 120, which may be connected to a lock, discussed in more detail below, that allows the endoscope 130 to be selectively attached to the handpiece 105 and selectively removed from the handpiece 105 by simple depression of button 120. The function of the lock and button 120 will be discussed in more detail below.

[0032] Handpiece 105 may further include a wire connector 125 that connects the handpiece 105 to the endoscope system 100, which may receive information through endoscope 130 or that may be generated within handpiece 105 and which may also update and change a view of a scene within the field of view of a camera (not shown). Endoscope system 100 may further include an endoscope rotation element 135, which allows the endoscope to be rotated about an axis defined by an endoscope tube 140. The endoscope tube 140 may be selectively inserted into a body of a patient for performing surgical, inspection, or other operations and inspections.

[0033] FIG. 2 illustrates a top view of an exemplary endoscopic unit 200 with a handpiece 205 incorporating an angle of view selector 210. The angle of view selector 210 may be implemented as a dial, as shown in FIG. 2, or may also be implemented as one or more interface elements 215a, as shown in FIG. 2. As shown in FIG. 2, the angle of view selector 210 is implemented as a dial, which may be selectively rotated to adjust an angle of view shown on a display based on the field of view of a scene as viewed through endoscope 245. In one embodiment, angle of view selector 210 may be implemented to provide three discrete and selectable angles of view, such as 0° (see reference numeral 235), 30° (see reference numeral 230), and 70° (see reference numeral 225). A user may interact with the angle of view selector 210 to align a selected angle of view with an indicator 220 positioned on the handpiece 205 in order to instruct an endoscope system to provide a view of the selected angle of view.

[0034] As shown in FIG. 2 and by way of example, a dial is implemented as angle of view selector 210 and has been rotated such that a 30° angle of view is aligned with indicator 220. In this exemplary case, an electrical signal may be generated by a sensor (not shown) associated with angle of view selector 210 (not shown), which indicates to an endoscope system that the user has selected a 30° angle of view for the field of view provided by the camera (not shown). Angle of view selector 210 may also include tactile elements 240, which assist a surgeon in turning the dial, increase grip friction, allow the surgeon to turn the dial with a single finger or a thumb, or otherwise facilitate the turning of the dial. In addition, or alternatively, audio and tactile feedback may be provided by handpiece 205 that indicates an angle of view that has been selected by the user without the user having to specifically look at indicator 220 or angle of view selector 210.

[0035] As noted above, angle of view selector 210 may also be implemented with user interface elements, such as one or more user interface elements 215a. An insert 215b may be used to cover one or more user interface elements 215a in a manner that allows endoscopic unit 200 to remain sealed while the one or more user interface elements 215a are exposed for receiving user input. In this embodiment, user interface elements 215a may allow a user to change a selected angle of view independent of angle of view selector 210. In this manner a user may press a directional element of one or more interface elements 215a or an opposite directional element which allows a user to scroll, in a continuous manner, between different angles of view in a field of view. For example, a user may scroll an angle of view of a field of view from 0° to 70° in an incremental manner (e.g., by 1° increments or half degree increments, by 2-5 degree increments, by 10 degree increments and etc.). It is possible that a user may also automatically flip between a 0° view, a 30° view, and a 70° view with a simple press of a one or more of user interface elements 215a as well (or in reverse with a push of another of the one or more of user interface elements 215a).

[0036] As previously discussed, endoscopic unit 200 may include an endoscope 245 that includes a rotation element 250 and an endoscope tube 255. Endoscope 245 may connect to handpiece 205 using the techniques, devices, and/or systems described herein.

[0037] FIG. 3 illustrates a bottom view of the exemplary endoscopic unit 300 with a handpiece 305 incorporating an endoscope install/release button 310. Endoscope install/release button 310 may be a depressible button, which may be depressed in response to a user pushing on endoscope install/release button 310. When the endoscope install/release button 310 is depressed, the endoscope 315 becomes unlocked from the handpiece 305 and may be removed by a user simply by pulling the endoscope 315 from the handpiece 305. The endoscope 315 may include an endoscope rotation element 320 and an endoscope tube 325. The handpiece 305 may further be connected by a connection 330 to an endoscopic system that processes visual data received from the camera (not shown) through the endoscope 315 and the user interface commands (e.g., a turn of a dial or a press of a button, etc.) provided via the handpiece 305.

[0038] FIG. 4 illustrates a horizontal cross section of an exemplary endoscopic unit 400 with a handpiece 405 connected to an endoscope element 460. The endoscopic unit 400 is shown in FIG. 4 with the handpiece 405 as a discrete unit, although the handpiece 405 may be connected to an endoscope system. As shown in FIG. 4, the endoscopic unit 400 also includes a dial 410, which receives interaction from a user and, in response, causes the endoscope system to alter an angle of view of a field of view of a camera (not shown).

[0039] The endoscopic unit 400 further includes a depressible endoscope install/release button 415, which selectively allows the endoscope 460 to be installed in and removed from the handpiece 405, as discussed below. The handpiece 405 includes a spring element 420, which may be connected to the endoscope install/release button 415 and allows the button 415 to be selectively depressed in response to a user pressing on the endoscope install/release button 415. The spring element 420 may be biased to cause the endoscope install/release button 415 to be disposed in and remain in an undepressed condition when pressure is not applied to the endoscope install/release button 415 by a user's hand or finger. When the endoscope install/release button 415 is depressed, the spring 420 compresses and pushes a chamfered dog 425a towards a top of the handpiece 405 and allows a corresponding spacer 425b to fully open a port 430 to receive an endoscope connector 435. The endoscope connector 435 may be disposed within port 430 when the endoscope install/release button 415 is depressed (or in some embodiments may be installed simply by pushing the endoscope connector 435 into port 430 and relying on chamfered dog 425a to be pushed out of port 430 by endoscope connector 435). When the endoscope install/release button 415 returns to an undepressed condition, the chamfered dog 425a slides into a mating chamfered channel 440 disposed between an endoscope spacer 445 and the endoscope connector 435. The chamfered dog 425a may include a portion that is angled to match a corresponding angle of the chamfer in chamfered channel 440 of endoscope 460. The chamfered dog 425a may also include a squared or right angle portion, which mates with a frontmost side of the endoscope connector 435 (e.g., a side of the chamfered channel 440 that is opposite the side of chamfered channel 440 that is angled to mate with chamfered dog 425a). In this manner, the chamfered dog 425a secures the endoscope 460 to the handpiece 405 by maintaining contact between the endoscope connector 435 and the handpiece 405 within the port 430 by applying pressure to the endoscope connector 435, which rigidly retains the endoscope 460 within the port 430.

[0040] The endoscope 460 may include a rotation element 455 and an endoscope tube 465, which allows the endoscope 460 to rotate around a horizontal axis defined by the endoscope tube 465.

[0041] FIG. 5 illustrates an exploded view of at least some constituent components of an exemplary endoscope 500 with a handpiece 505 incorporating an endoscope install/release button 520 and an angle of view selector 510. Endoscope 500 may include an angle of view selector 510, one or more user interface elements 515a and an insert 515b. The handpiece 505, angle of view selector 510, and one or more user interface elements 515a, and insert 515b may be similar in implementation and description to similar elements described above with respect to FIG. 2. As described herein, the angle of view selector 510 may be a dial or implemented as one or more user interface elements 515a to cause an endoscopic system to change an angle of view in a field of view based on user input. In this manner, a user may interact with an angle of view selector 510 or one or more user interface elements 515a to adjust the angle of view or field of view according to the user's preferences. The angle of view selector 510 may trigger a mechanical or electrical sensor, which causes a signal to be transmitted to an endoscope system that indicates to the endoscope system that a particular angle of view in the field of view has been selected by the user.

[0042] The handpiece 505 may further include a button 520 having a lock 525 and a chamfered dog 530, which allow an endoscope 540 to be inserted into a port 535 of the handpiece 505 and retained therein, according to the foregoing disclosure. Endoscope 540 may include an endoscope rotation element 545 and an endoscope tube 550. Endoscope 540 may further include an endoscope connector 555, which includes a chamfered channel 560. The chamfered channel 560 may interface with the chamfered dog 530 to secure the endoscope 540 within the port 535 of the handpiece 505 according to the foregoing description.

[0043] In this manner, a simple connection is provided between the endoscope 540 and the handpiece 505. A user may simply push the endoscope 540 into the port 535 and as the endoscope connector 555 contacts the chamfered dog 530, the endoscope connector 555 will overcome spring pressure exerted by a spring element (not shown in FIG. 5) to push the chamfered dog 530 out of the path of the endoscope connector 555 in the port 535 and allow the endoscope connector 555 to fully seat within the port 535 of the handpiece 505. Alternatively, the user may apply pressure to the endoscope install/release button 520 while inserting the endoscope connector 555 into the port 535 to a point where the endoscope connector 555 passes the chamfered dog 530 and thereafter releases pressure to the endoscope install/release button 520. In either case, the chamfered dog 530 may, by pressure exerted by the spring element (not shown in FIG. 5), rest within the chamfered channel 530 and secure the endoscope 540 to the handpiece 505 according to the foregoing description. To remove the endoscope 540, the endoscope install release button 520 may be depressed by a user to disengage the chamfered dog 530 from the chamfered channel 560 and allow the endoscope 540 to be removed from the handpiece 505 through the port 535.
