The two-position handpiece coupling seal includes a neck disposed at a first end that is configured to receive an implement. The two-position handpiece coupling seal has a first seal disposed about the neck of the two-position handpiece coupling seal. The first seal is configured to engage with a surface of a housing of a handpiece that uses the two-position coupling seal in a first position. The two-position handpiece coupling seal has a second seal disposed about a bore of the two-position handpiece coupling seal at a second end of the two-position handpiece coupling seal opposite the first end. The bore is configured to receive a driveshaft and the second seal is configured to sealingly engage with the driveshaft when the bore receives the driveshaft. ## Claims ### Claim 1 A device comprising: a handpiece having a housing; a two-position handpiece coupling seal within the housing, the two-position handpiece coupling seal including: a neck disposed at a first end of the two-position handpiece coupling seal, the neck being configured to receive an implement; a first seal disposed about the neck of the two-position handpiece coupling seal; and a second seal disposed about a bore of the two-position handpiece coupling seal at a second end of the two-position handpiece coupling seal opposite the first end, wherein the bore is configured to receive a driveshaft and the second seal is configured to sealingly engage with the driveshaft when the bore receives the driveshaft; and a biasing member that abuts the second end of the two-position handpiece coupling seal, wherein: the biasing member is configured to bias the two-position handpiece coupling seal into a first position where the first seal sealingly engages with a surface of the housing; and the two-position handpiece coupling seal is configured to be in a second position when the neck receives the implement, wherein when the neck and the first seal are in the second position, the first seal is spaced away from the surface of the housing in the second position. ### Claim 2 (depends on 1) The device of claim 1, wherein the two-position handpiece coupling seal further comprises a recess at the bore where the recess is configured to receive a driveshaft pin of the driveshaft when the bore receives the driveshaft. ### Claim 3 (depends on 2) The device of claim 2, wherein the device further comprises a motor and the driveshaft extends from the motor to the two-position handpiece coupling seal such that the two-position handpiece coupling seal couples with the motor when the two-position handpiece coupling seal receives the driveshaft at the bore. ### Claim 4 (depends on 2) The device of claim 2, wherein when the neck receives the implement, the two-position handpiece coupling seal is configured to move to the second position where the first seal is spaced away from the surface of the housing. ### Claim 5 (depends on 4) The device of claim 4, wherein when a motor coupled with the driveshaft rotates the driveshaft during operation of the device, the two-position handpiece coupling seal, the first seal, and the second seal rotate with the driveshaft. ### Claim 6 (depends on 1) The device of claim 1, wherein the neck comprises an implement coupling member recess configured to receive the implement. ### Claim 7 (depends on 6) The device of claim 6, wherein the implement coupling member recess has a triangular configuration. ### Claim 8 (depends on 1) The device of claim 1, wherein the biasing member is a compression spring. ### Claim 9 A two-position handpiece coupling seal comprising: a neck extending from a first end of the two-position handpiece coupling seal, the neck being configured to receive an implement; a first seal extending around an outer surface of the neck; a second seal disposed about a bore extending through the neck from the first end of the two-position handpiece coupling seal to a second end of the two-position handpiece coupling seal opposite the first end, wherein the bore is configured to receive a driveshaft and the second seal is configured to sealingly engage and rotate with the driveshaft when the bore receives the driveshaft; and a biasing member that abuts the second end of the two-position handpiece coupling seal, wherein: the biasing member is configured to bias the two-position handpiece coupling seal into a first position where the first seal sealingly engages with a housing surface in the first position; and the two-position handpiece coupling seal is configured to be in a second position when the neck receives the implement, wherein when the neck receives the implement, the two-position handpiece coupling seal is configured to move to the second position where the first seal is spaced away from the housing surface. ### Claim 10 (depends on 9) The two-position handpiece coupling seal of claim 9, wherein the two-position handpiece coupling seal further comprises a recess at the bore where the recess is configured to receive a driveshaft pin of the driveshaft when the bore receives the driveshaft. ### Claim 11 (depends on 9) The two-position handpiece coupling seal of claim 9, wherein the neck comprises an implement coupling member recess configured to receive the implement. ### Claim 12 (depends on 11) The two-position handpiece coupling seal of claim 11, wherein the implement coupling member recess has a triangular configuration. ### Claim 13 (depends on 9) The two-position handpiece coupling seal of claim 9, wherein the first seal and the second seal are configured to rotate with the driveshaft when the driveshaft rotates. ### Claim 14 (depends on 9) The two-position handpiece coupling seal of claim 9, wherein the two-position handpiece coupling is configured to abut a biasing member, where the biasing member is configured to move the two-position handpiece coupling between a first position and a second position. ### Claim 15 (depends on 14) The two-position handpiece coupling seal of claim 14, wherein the biasing member is a compression spring. ### Claim 16 (depends on 9) The two-position handpiece coupling seal of claim 9, wherein the two-position handpiece coupling further comprises a lip disposed about the first seal, where the lip defines a recess within which the first seal sits. ### Claim 17 A device comprising: a handpiece having a housing; a two-position handpiece coupling seal within the housing, the two-position handpiece coupling seal including: a neck disposed at a first end of the two-position handpiece coupling seal, the neck comprising an implement coupling member recess configured to receive an implement; a first seal disposed about the neck of the two-position handpiece coupling seal; and a second seal disposed about a bore of the two-position handpiece coupling seal at a second end of the two-position handpiece coupling seal opposite the first end, wherein the bore is configured to receive a driveshaft and the second seal is configured to sealingly engage with the driveshaft when the bore receives the driveshaft; and a biasing member that abuts the second end of the two-position handpiece coupling seal, wherein: the biasing member is configured to bias the two-position handpiece coupling seal into a first position where the first seal sealingly engages with a surface of the housing in the first position; and the two-position handpiece coupling seal is configured to be in a second position when the neck receives the implement, wherein when the neck receives the implement, the two-position handpiece coupling seal is configured to move to the second position where the first seal is spaced away from the surface of the housing. ### Claim 18 (depends on 17) The device of claim 17, wherein the device further comprises a motor and the driveshaft extends from the motor such that the two-position handpiece coupling seal couples with the motor when the two-position handpiece coupling seal receives the driveshaft at the bore. ### Claim 19 (depends on 18) The device of claim 18, wherein the motor rotates the driveshaft during operation of the device and the two-position handpiece coupling seal, the first seal, and the second seal rotate with the driveshaft. ### Claim 20 (depends on 17) The device of claim 17, wherein the two-position handpiece coupling seal further comprises a recess at the bore where the recess is configured to receive a driveshaft pin of the driveshaft when the bore receives the driveshaft.
