The nominal value may be about 15 mm (0.60 inches). The collar 88 may have a substantially trapezoidal shape when viewed from the side. 5E, when viewed from the distal end of the collar 88, the collar 88 is shaped like a circular arc. It is aligned with the diameter D1 of the part.

[0084] Tabs 92A, 92B each have a centerline 98A of each of tabs 92A and 92B, For example, the first tab 92A may be substantially symmetrical with respect to the first , i.e., upper wedge surface 100A1 and a second, i.e., lower wedge surface 100A2. and may have exemplary tapered sides separated by a tab wedge angle α1. Each of the rusted surfaces 100A1 and 100A2 is separated from the center line 98A by an angle of α1 / 2. Exemplary nominal values ​​for α1 may be about 32° and α1 / 2 is about 16°. Thus, both wedge surfaces 100A1 and 100A2 are at an angle to centerline 98A. The tip distance from the distal edge 94 to the tip 96A, i.e., The axial length of the tab 92A is a length L1. Therefore, the inner diameter D1 can be maintained regardless of the thickness.

The first is a parallel distance below the mounting axis 90, as best shown in Figs. 5D and 5G. An exemplary nominal value for B1 is approximately 2.5 mm (0.10 inches). The wedge surfaces 100A1, 100A2, 100B1, and 100B2 can be respectively It is angled in that it is disposed at an angle relative to the mounting axis 90 .

[0086] The tabs 92A, 92B also define wedge surfaces 100A1, 100A2, 100B1, 100B 2, one on each of the nominal tab contact points 101A1, 101A2, 101B1, 101 The nominal tab contact points 101A1, 101A2, 101B1, 101B2 may be partially defined. The role of 1B2 is explained in more detail below.

[0087] The mounting base 62 includes an exemplary spring loaded ball based detent plunger 104, That is, a plug for receiving a collar detent plunger 104, best seen in FIG. The alignment interface 72 may further include a receiving aperture 102. The receiving opening 102 may include a counterbore 106.

[0088] The detent plunger 104 can be purchased commercially. The following description of the ball plunger 104 is exemplary and is not applicable to the ball plungers referenced later. The exemplary plunger 104 includes a closed end 110 and an open end 112. The vent may include a substantially constant diameter sleeve 108 formed of steel. A durable plunger ball 114 (e.g., steel, ceramic) may be included. A slit 114 is disposed within the sleeve 108 and extends from the open end 112, i.e., protruding from the closed end 112. 1, disposed within sleeve 108 between ball 114 and closed end 110. The open end 112 is fitted with a compression coil plunger spring 116. The open end 112 is fitted with a ball 114 and 1, an inner lip 118 is provided which traps the spring 116 within the The outer lip 120 may be formed to provide a recess 122 for receiving the sleeve 108. The counterbore 106 can be used to accommodate the outer lip 120. 9, so that the plunger 104 is substantially flush with the mounting surface 91 of the collar 88. While allowing the ball 114 to be flush with the mounting surface 91, the ball 114 extends beyond the mounting surface 91 and into the collar 8. The plunger 104 can extend through the inner diameter D1 of the sleeve, the coil spring, and the Although described as including a rod and a ball, the structure described is merely exemplary. Alternatively, alternative plungers can be used. For example, the plunger may be a ball-shaped plunger. A bullet-shaped plunger projectile may be used instead of the plunger projectile, or Instead of a ball, a double-ended cylinder with one or both ends arcuate may be used. Alternatively, the plunger may be actuated using a spring type other than a coil spring, for example a leaf spring. Alternatively, the plunger may be driven primarily by a spring and a The arcuate plate acts as both a projectile that is received by the recess when aligned. The arcuate leaf spring may be bent or cantilevered. The plunger may have a separate spring. Instead of the spring and projectile, a dome spring may be further alternatively included. and elastically and substantially elastically deflecting at the apex in the supported state to invert the apex portion of the dome. Its partial hemispherical shape, i.e., a dome shape when placed over the detent notch The plunger may be in the form of a resilient thin-walled partial hemisphere that is capable of self-restoring. Alternatively, the magnetic or electromagnetic properties of the components may be relied upon to direct the projectile in a desired direction. The detent can be biased to engage the detent notch.

[0089] To facilitate the formation of the receiving opening 102 and the counterbore 106, the bottom 12 of the collar 88 is 4, a detent plunger is aligned opposite the receiving opening 102 and counterbore 106. An access hole 122 may be formed to receive and seat the cartridge 104 in the opening 102. The plunger 104 is fitted into the receiving opening 102 by an interference or press-fit relationship therebetween. 02. A portion of the receiving opening 102 is held by the plunger 104 through the receiving opening 102. 104. To facilitate aligned reception of the plunger 104, The access hole 122 may be chamfered ( The plunger 104 is shown in the opening 102 of FIG. .

[0090] The alignment interface 72 includes an annular portion 95 and tabs 92A, 92B, and Collar 88 containing plunger 104 and handpiece housing 106 are shown in FIG. 6A-6D. and a complementary feature on housing 58. Such complementary features may include a first tab 9 2A and a first tab receiving channel 128A for receiving the second tab 92B, respectively. and second tab receiving channel 128B, and a via for engagement by plunger 104. The bias surface 130 is provided by a detent notch 132 that defines the bias surface 130. Tab receiving channels 128A, 128B may be aligned with collar tabs 92A, 92B. The housing 58 is disposed thereon for mating reception.

[0091] The handpiece housing 58 has a gripping surface 134 and a relatively concave engagement surface 136. The recessed engagement surface 136 is located proximal to the gripping surface 134. Grip 38 defines the boundary between and connects the two surfaces 134 and 136. The face 134 may have a first surface diameter D2. An exemplary nominal value for D2 is about 22 mm ( 0.90 inches). The engagement surface 136 may have a smaller second surface diameter D3. An exemplary nominal value for D3 may be approximately 20 mm (0.80 inches). Both D1 and D2 are centered about a housing axis 140 along which the housing 58 extends. Given the exemplary values ​​of D2 and D3, an exemplary height of the peripheral wall 138 may be The height H1 may be about 1 mm (0.04 inches).

[0092] The diameter D3 of the engagement surface 136 is smaller than the inner diameter D1 of the collar 88, so that the surface 13 6, and collar 88 is such that housing axis 140 is substantially aligned with mounting axis 90. A collar 88 may be slidably disposed on the proximal end of the housing 58 of the handpiece 54. The hand switch 52 is coupled to the housing 58. In this case, the housing axis 140 may coincide with the mounting axis 90. As shown in FIG. The mounting axis 90 is perpendicular to the direction of the pivot axis 86. Thus, the housing axis 140 is , when the hand switch 52 is coupled to the housing 58, it also moves vertically in the direction of the pivot axis 86. The peripheral wall 138 extends radially outwardly relative to the mounting axis 90 and has an engagement surface 138. 36 may be connected to grip surface 134. Peripheral wall 138 may define a first tab receiving channel. 128A, i.e., a first channel 128A and a second tab receiving channel 128B, That is, a second channel 128B can be defined.

[0093] The first channel 128A may have an axial length L2. More specifically, the tip 96 A channel end 142A similar to A is spaced a length L2 from the proximal edge 144 of the peripheral wall 138. The second channel 128B may also have a length L2 and may be disposed at a length similar to the tip 96B. The extended channel end 142B is spaced a length L2 from the proximal edge 144 of the peripheral wall 138. An exemplary nominal value for L2 may be approximately 15 mm (0.60 inches). The axial length L2 of the channels 128A, 128B is equal to the axial length L1 of the tabs 92A, 92B. The first channel 128A has upper and lower wedge surfaces 146 The second channel 128B has corresponding upper and lower chains. The upper and lower wedge surfaces of both channels are There is an included angle α2 therebetween. The angle α2 may be substantially equal to the angle α1. An exemplary nominal value for α2 may be approximately 34°.

[0094] The channel 128A is aligned with respect to a channel centerline 147A of the tab receiving channel 128A. For example, the first channel 128A is α2 / α3 from the centerline 147A. The upper wedge surface 146A1 and the lower wedge surface 146A2 are separated by an angle of 2. Similarly, the second channel 128B may have an α2 1 / 2, and its upper wedge surface 146B1 and its lower wedge surface 146B 2. As noted above, an exemplary nominal value for α2 may be 34°, with α2 / 2 being approximately 1 7°. Therefore, the wedge surfaces 146A1 and 146A2 are Therefore, the wedge surfaces 146B1 and 146B2 are angled relative to the centerline 14 7B. The channel centerline 147A is angled relative to the centerline 147 in FIGS. 6B and 6C. As best shown, it may be located a distance B2 below the mounting axis 90. The value of B2 is , B1, and an exemplary nominal value for B2 is about 2.5 mm (0.1 0 inches).

[0095] The channel wedge surfaces 146A1 and 146A2 are aligned with the tab wedge surfaces 100A1, 100A 2, along with nominal channel contact points 148A on channel wedge faces 146A1, 146A2. 1, 148A2, and tab contact points 101A on tab wedge surfaces 100A1, 100A2. 1 and 101A2. In the engaged position of the hand switch 52 on the housing 58, The wedge surfaces 100A1 and 100A2 are respectively connected to the tab contact points 101A1 and 101A2. a channel wedge surface 146A1 at channel contact points 148A1, 148A2 in contact with the 146A2. The wedge surfaces 146B1, 146B2 of the second channel 128B The channel contact points 148B1, 148B2 are similarly aligned with the tab contact points 10 of the second tab 92B. The distance is determined by the engagement of the wedge surfaces 146B1 and 146B2 with the grooves 101B1 and 101B2. Such engagement occurs when the tips 96A, 96B are engaged with the ends 142A of the first channel 128A or 14. Prior to engaging the distal end 142B of the second channel 128B, and prior to engaging the proximal edge 144 of the collar 88 This occurs sometime before engaging distal edge 94.

[0096] The housing 58 may have a diamond-like carbon ("DLC") coating. DLC coatings provide wear resistance and a lower coefficient of friction for the coated surface. may be beneficially provided.

[0097] The collar detent plunger 104 and the detent notch 132 are attached to the mounting base. The detents 149 are cooperatively defined to hold the hand switch 52 in place. The tabs are held on the housing 58 by the wedge faces 100A1, 100A2, 100B1, and 100B2. The first channel wedge surfaces 146A1, 146A2 and the second channel wedge surface 146 The detent notch 132 may function to bias the B1, B2 relative to the B1, B2. It may be formed as a recess in the engagement surface 136 and may be symmetrical about a notch centerline 151 . The notch 132 need not be symmetrical, but may be symmetrical if formed with a rotary tool, e.g., a mill. The bias surface 130 of the notch 132 is engaged with the mounting axis 90. An exemplary nominal value of α3 relative to the housing axis 140 is approximately 1 With the mounting base 62 installed in the housing 58, the plunger The ball 114 is partially received by the notch 132, as shown in FIG. The bias of the plunger spring 116 within the sleeve 108 and against the ball 114 causes the ball 14 against bias surface 130, and then tab wedge surfaces 100A1, 100A2 , 100B1, 100B2 to contact first channel wedge surface 146 at their respective contact points. A1, 146A2 and second channel wedge surfaces 146B1, 146B2.

[0098] The biasing surface 130 is configured to bias the plunger 104 toward the detent notch 132 that is engaged by the plunger 104. The notch can also be at 90 degrees to the housing axis 140, or A retaining edge 150 which may be arcuate or at an angle greater than angle α3 but less than 90 degrees. The retention lip 150 is necessary to remove the hand switch 52 from the housing 58. The edge 150 can advantageously increase the axial force exerted by the ball 114 against the plunger. A sudden displacement is applied to the spring 116. The increase in displacement also increases the force on the ball 114. This translates into an increase in force in the axial direction, i.e., parallel to the housing axis 140. 58, which may result in unintentional removal of the handswitch 52 from the housing 58. Resist something.

[0099] Tabs 92A, 92B and channels 128A, 128B connect handswitch 52 to the housing. 5. This facilitates proper alignment of the housing 58 of the handswitch 52 with the housing 58. 8. The detents 149, tabs 92A, 92B, and channel 12 The combination of 8A and 128B allows the hand switch 52 to be properly positioned in the housing 58. Then, place the hand switch 52 on it and connect the connector 56 to the housing 58. The hand switch 52 can be held on the housing 58 before connecting the detent. Exemplary force required to remove hand switch 52 from housing 58 against 149 The force can range from 27 to 36 newtons (6 to 8 pounds).

[0116] The lever extension 70 as shown in FIGS. 9A-9F may include an extension slide body 246. The sliding body 246 may be substantially rectangular and may extend from the distal end 249 of the extension 70 to the proximal end 250 of the extension 70. 0. The extension 70 is disposed on the lever 64. In this case, the extension slide axis 248 coincides with the lever axis 152 or is substantially the same as the lever axis 152. It may be parallel to 52.

[0117] The sliding body 246 receives or fits into the second track 162. The second track 162 has a lever extension sliding surface 252 that is received by the lever extension sliding surface 252. , the sliding surface 232 may be, for example, on or instead of the first track 162. The exemplary sliding surface 252 may be disposed inside the sliding body 246 having a length L11. A T-slot 254 that can be extended and aligned with the axis 248. An exemplary nominal value for L11 may be approximately 77 mm (3.0 inches).

[0118] The outwardly facing contact surface 188 may be substantially continuous from the distal end 249 to the proximal end 250. An engagement head 258 may be provided at the distal end 249 of the extension 70. 8 extends upwardly from contact surface 188 for engagement by the thumb or finger of a user of tool 50. The plurality of distal engagement surfaces 262 provide an angled engagement surface 260 for engagement with a user's finger or may be provided on a contact surface 188 proximate the head 258 for engagement by a thumb. The engagement surface 262 may be defined by a recess or by a protrusion. The elongate portion 70 may have a plurality of proximal engagement surfaces 264 within the contact surface 188 adjacent the proximal end 250. do.

[0119] In the upper surface 266 of the T-slot 254, there are a plurality of detent recesses, e.g., four detent recesses, i.e. That is, the notch, the first detent recess 268A, the second detent recess 268B, the third A fourth detent recess 268C, and a fourth detent recess 268D are formed therein. The extension plunger 172 may be positioned for engagement by a ball (not shown). The recesses 268A, 268B, 268C, and 268D may be substantially hemispherical. 68A, 268B, 268C, and 268D are recesses 268A and 268D that are connected to the plunger 172. B, 268C, 268D, elongated laterally to make them insensitive to lateral alignment The recesses 268A, 268B, 268C, and 268D can be aligned in the axial direction, i.e., 248. The extension 70 is in a fully retracted position. , for example, when the proximal end of extension 70 is engaged with the distal end of end wall 182. The first detent recess 268A, which is the most proximal recess, is aligned with the plunger 172. The fourth recess 268D, which is the most distal recess, may be located at the point where the extension 70 is fully extended. When in the extended position, for example, the travel limiting pin 178 is in the proximal end 2 of the pin slot 216. 18, it may be aligned with plunger 172.

[0120] The pin slot 216 may be formed in the upper surface 266 and at least a portion of the extension 70. For a contemplated exemplary travel distance L12, an exemplary width W3 may be extended axially. An exemplary nominal value for W3 may be approximately 2 mm (0.08 inches). A nominal value may be about 40 mm (1.6 inches). Pin 178 is attached to lever extension 70. is slidably received by lever 64 and then received in slot 216. The recess 216 may have a depth H5 that is less than the thickness H6 of the extension. can be about 1 mm (0.04 inches). An exemplary nominal value for H6 is about 1.2 mm ( 0.05 inches). The slot 216 extends through the entire thickness of the extension 70. It is not necessary for the extension 70 to slide in the desired manner, but it may be necessary to insert the extension 70 into the T-slot. This can help reduce the ingress of debris and the associated increase in resistance to sliding. do.

[0121] The extension 70 is then slid over the lever 64 and the pin 178 is then attached to the lever 64. Extending from inside 160 through pin opening 176 of lever 64 into slot 216 As described above, the pin opening 176 is blind. If provided as a hole, the clearance hole (not shown) aligns with the slot 216. After the extension 70 is slid onto the lever 64, the clearance The pin 178 is aligned with the pin opening 176 through the clearance hole. The height of the installed pin 178 is equal to the height of the slot 216. It must fit within the available height. If slot 216 extends through the extension In this case, the pin 178 is positioned below the contact surface 188 for the comfort of the user of the handswitch 52. It should be.

[0122] In operation, the handswitch 52 couples the tabs 92A, 92B to the first channel 128A and 4. Align the collar 88 with the second channel and axially slide the collar 88 onto the proximal end 60 of the housing 58. The mounting shaft 90 is then slid into the housing 58. The offset B1 of the cores 98A, 98B and the channel center relative to the housing axis 140 The offset B2 of lines 147A, 147B allows for faster initial alignment and Visual cues help prevent incorrect orientation and installation of the 58 hand switch The tabs 92A, 92B may provide a user with a first channel 128A and a second channel 128B. The tab wedge faces 100A1, 100A2, 100B1, 100 B2 is the first channel wedge surface 146A1, 146A2 and the second channel wedge surface The wedge surfaces rotate the housing 58 and the hand switch 52 in a coordinated manner. The handwheel can be moved to the engaged position by continuing the axial movement therebetween. The handpiece housing 58 is rotationally aligned with the handpiece housing 58, i.e., aligned As collar 88 approaches the fully seated position, plunger The ball 114 of 104 passes over the edge 150 of the notch 132 and falls into the notch 132 . Upon entering the notch 132, the ball 114 is forced against the biasing surface 130 by the spring 116. The bias force is applied to the collar 88 and thus the hand switch 52 is biased toward a seated position on the housing 58. The first tab contact points 101A1, 101A2 are in contact with the first channel contact points 148A1, 14 8A2, and the contact points 101B1 and 101B2 of the second tab are in contact with the second channel. is in contact with the contact point.

[0123] With the hand switch 52 installed in the housing 58, the connector 56 The connector 56 holds the hand switch 52 on the housing 58. can help you do so.

[0124] In use, the hand switch operates a tool 50, e.g., a saw, a burr, a drill, etc. To do so, the lever 64 is selectively pivoted about a pivot axis 86 toward the housing. The handpiece 54 includes a housing 58, as previously described. The safety switch 54 may include a magnetic field sensor 59 disposed within a housing 58. When the latch 68 is in the unlocked position and the lever 64 is potentially facing the housing 58, When displaced downward relative to the housing 58, the magnetic field sensor 59 contacts the switch magnet 206. The sensor 59 is connected to the sensor 52 by signal conductor 55 or wirelessly, as described above. Similarly, the motor 61 disposed within the housing 58 may be connected to the controller 63 via a may be connected by power conductors 57 to the console 53 and a power source therein (not shown). The communication of power and control signals between the handpiece 54 and the console 53 is via a connector. 56.

[0125] The operation of the tool 50 relies on a magnetic field sensor 59 detecting the magnet 206. Controller 63 provides a change in power to the drive motor 61 in response to the detected magnetic field strength. Therefore, as the magnet 206 approaches the sensor 59 within the distance sensing range, The power and / or speed of the tool 50 is increased when the switch 68 is in the locked position. When the magnet 206 is moved, the magnet 206 is kept out of the distance sensing range of the sensor 59 and the motor 61 is operated. I can't do that.

[0126] To operate tool 50 after hand switch 52 is installed in housing 58, A switch 68 is located on the lever in the unlocked position. 8 is placed in the unlocked position by sliding it proximally from the locked position. To achieve this, the user may move one or both of the arms 236A, 236B in one or more Engage the switch 68 with your fingers to apply a load in a direction parallel to the switch sliding axis 230, and Switch 68 can be displaced axially in the proximal direction, ie, in the direction of axis 230. Thus, the switch 68 can be rotated without exerting any lever load on the switch spring 66. 2, the switch plunger 198 can be moved to the unlocked position. Sufficient axial force must be applied to overcome the detent load resulting from engagement of arm 2. 36A, 236B. Switch 68 is By overcoming the load, it can be displaced axially to the unlocked position. Movement of the switch 68 toward the release position causes the proximal end of the sliding body 228 and the track end 208 and the engagement of the magnet housing 204 with the proximal end 210 of the slot 202. Holding the switch 68 in the unlocked position can be limited by one of the following: 98 can be assisted by engaging the recess 242B. to displace the switch 68 from the locked position to the unlocked position, or A sliding member tends to pivot the lever about pivot axis 86 to move it from the locked position to the unlocked position. No force perpendicular to the moving shaft 230 is required. The lever 64 moves against the bias of the switch spring 66. As described above, the magnet 206 in the switch 68 is When within range, the sensor 59 may provide a signal to the controller 63 . The controller 63 then directly or indirectly couples the drive motor 61, also within the housing 58. The tool 50 can be energized to initiate movement of the tool bit 280. Accidental actuation is prevented by sliding switch 68 to the locked position. Release of lever 64 by the lever causes spring 66 to move lever 64 away from housing 58. It can be pivoted to the off position.

[0127] The switch 68 is operable by a user by depressing the switch 68 axially in a distal direction. The action is to move the switch 68 to the unlocked position. The engagement between plunger 198 and recess 242B is essentially the same as that in FIG. The detent load is overcome by the user. The switch 68 is distally displaced by the user. The switch 68 is slid in the direction of the lever 64, and the movement of the switch 68 relative to the lever 64 causes the magnet housing 204 and the switch The locking position of the switch 68 is limited by engagement with the distal end 212 of the rod 202. Retention may be assisted by plunger 198 engaging recess 242A.

[0128] The hand switch 52 can be in a fully extended position, as shown in FIGS. 1, 2 and 3B. The extension in a fully extended position as shown in FIG. 3A, or any position in between. 70. Of the two shown for the exemplary handswitch 52, There is an intermediate position, but there may be more or fewer intermediate positions. A corresponding one of the detent recesses 268A, 268B, 268C, 268D of the long portion 70 The plunger 172 may be placed in any of four exemplary positions associated with receiving the ball in one of the four positions. By mounting the plunger 172 on the extension 70 and providing a detent recess, Thus, the same detent effect can be achieved. A, 268B, 268C, and 268D may be spaced apart by a distance L13, and the recesses The total distance between 268A and 268D is three times the distance L13. The nominal value may be approximately 13 mm (0.50 inches). Recesses 268A, 268B, 268C , 268D may include a portion of a lever extension multi-position detent. 0 users with a variable length lever that can be adjusted to fit the user's hand size. Provide.

[0129] When extension 70 is in the fully extended or stored position, lever extension 70 and the flush outer surface 186 of the proximal end 180 of the lever 64. In the extended position, the finger rests against the surface of the movable member 10 and the movable member 11. The movable member 10 and the movable member 12 cooperate to present a substantially continuous smooth surface for engagement by a finger. Retention of extension 70 is supported by engagement of extension plunger 172 with recess 268D. The user can rotate the extension 70 in the desired extension direction relative to the mounting base 62. The pushing engagement displaces the extension 70 axially, i.e., against the shaft 248. The head 258 can slide along the extension 70 for finger engagement. The extension 70 is provided with what may be the most prominent engagement feature of the finger. Complementary engagement features are provided by distal and proximal engagement surfaces 262, 264. Such features 258 , 262 , 264 may resist slippage of the fingers across the extension 70 . To slide the extension 70 from the extended position toward the fully extended position, the extension Sufficient to overcome the detent force associated with the engagement of plunger 172 with recess 268D. A sufficient axial force must be applied to extension 70 in the desired direction of movement.

[0130] An exemplary extension length of the combined lever 64 and extension 70 is the sum of L4, and may be substantially equal to the distance between the proximal end 250 and the distal end 249 of the lever extension. The total length of such drawers is approximately equal to 102 mm (4 inches). An exemplary fully extended length of the lever 64 and extension 70 is approximately 142 mm (5.6 The extension 70 may be anywhere between the extended position and the fully extended position. The user may find it useful to set the extension to a specific intermediate position. It can be seen that the intermediate detents that may be provided by the recesses 268B and 268C. The position is determined by the lever extension moving along axis 248 with little or no axial force. The illustrated extension 70 is recessed. The two intermediate detent positions associated with the portions 268B and 268C are The number of positions may be less or more.

[0131] Movement of extension 70 toward its fully extended position and away from end wall 182 The final limit is provided by the engagement of the pin 178 with the proximal end 218 of the slot 216. Retention of extension 70 in the fully extended position engages extension plunger 172 with recess 268A. The return of the extension 70 to the extended position can be assisted by The engagement between the proximal end 250 and the end wall 182 and the pinion of the slot 216 against the distal end 214 2. Rotate extension 70 axially in the proximal direction until movement is limited by one of engagements of bolts 178. Retention of the extension 70 in the extended position can be achieved by pulling the extension plan. This can again be assisted by engaging jar 172 with recess 268D.

[0132] In any extended position, i.e., any position other than the extended position, the extension The outer surface 188 and head 22 are separated from the proximal end 180 for engagement by the fingers of the 58. The contact pads are of importance, including the width of the extension, e.g., about 10 mm. The lever 6 may have a length of approximately 85 mm (3.3 inches) and a length of approximately 85 mm (0.40 inches). This is facilitated by placing extension 70 on track 162 on the outside 164 of Such a large contact area provides a comfortable grip for the user when pushing the extension 70 to operate the tool 50. Improves finger comfort.

[0165] When the connector 56 is fully assembled, the outer sleeve 305 is substantially mated. The nut 314 extends over the inner sleeve 308 and the nut 314 .

[0166] In operation, the uninserted connector 56 extends beyond the first outer diameter of the insertion portion 320. 3 and has a wedge 330 extending radially outward through window 322. In the unlatched state, the outer sleeve 305 is in a latched position relative to the inner sleeve 308. In the latched position, the wedge 330 engages with the window 322 of the outer sleeve 305. Qualitatively axially aligned, beam 340 is not substantially deflected, and wedge 330 The connector 56 is configured to extend beyond the first outer diameter of the insert portion 320. The mating surface 328 is used to align the handpiece 54 and connect the connector 56 to the handpiece. The connector 56 is then oriented relative to the handpiece 54. During insertion, the handpiece 54 is wedged against the inner diameter of the receptacle 321. The engagement of the inclined surface 325 of the wedge 330 against the resistive force of the beam 340 causes the wedge 330 to winch. The inner sleeve 308 and the outer sleeve 305 are biased downward into the dough 322. It remains in the latched position, with the wedge 330 aligned with the window 322. Once 322 is axially aligned with the engagement recess 335 of the handpiece 54, The wedge 330 is restored to the extended position by the elastic beam 340. As a result, the wedge 3 30 is partially disposed in recess 335 .

[0167] The wedge 330 tends to resist withdrawal of the connector 56 from the handpiece 54. However, by applying a sufficient pulling force to the outer sleeve 305, the The resistance to penetration is the action of the distal engagement surface 324 of the window 322 acting on the inclined surface 325. The force against the inclined surface 325 can be overcome initially by the stop of the wedge 330. Pressing the stop surface 326 against the proximal end of the recess 335 secures the inner sleeve to the handpiece 54. As the pulling force applied to the outer sleeve 305 increases, The distal engagement surface 324 of the window 322 acts against the inclined surface 325. The force on 05 overcomes the resistance of beam 340 and displaces wedge 330 radially inward. Such displacement of the wedge causes the outer sleeve 305 to move relative to the inner sleeve 308. axially shifting so that wedge 330 is axially offset from alignment with window 322. The movable member 100 can be moved to a release position between the movable member 100 and the movable member 102 as shown in FIG. 3, with the outer sleeve 305 in a release position relative to the inner sleeve 308, The wedge 330 is pulled out, i.e., removed, from the recess 335. Such removal from recess 335 removes connector 56 from receptacle 321. When removed from the handpiece 54, the connector 56 is The restoring force of the beam presses 325 against the distal surface 324 of the window 322, causing the latch 305 , and can be restored to its original position, within the slidable range between the inner sleeve 308 and the outer sleeve 305 . The actuator generates relative axial motion across the axis.

[0168] Since the stop surface 326 engages the proximal end of the recess 335, only the cable 51 can be pulled. does not result in the connector being released. Thus, accidental removal of the connector 56 is prevented. Limited.
