Fig. 1 has shown the perspective view of Curette system 100.Curette system 100 comprises handle 102, axle 104 and head 106.Handle 102 comprises lever 108 and pedestal 103.Lever 108 is configured to by the user towards pedestal 103 extruding.Extrusion lever 108 and pedestal 103 rotate lever 108 along clockwise direction.Rotating lever 108 cause being positioned at push rod in the axle 104 in axle 104 along a direction (that is, shown in y direction in the direction) translation, this will further be described in detail below.
With reference to figure 2, shown the enlarged drawing of head 106, wherein partly excised the far-end of axle 104 for diagram.The far-end of push rod 110 be shown as being attached to push away the silk 112.Push away silk 112 rings and pass curet tip 114.Curet tip 114 can be around the point of rotation 116 rotations.The pin (not shown) is passed axle 104 far-end and is passed curet tip 114 (for example at the point of rotation 116), with respect to the near-end fix in position of axle 104 with curet tip 114.Push rod 110 causes curet most advanced and sophisticated 114 around the point of rotation 116 rotations along the translation of y direction, promptly around the axle rotation along the x direction.Direction of rotation (that is x direction) is basically perpendicular to the translation direction (that is y direction) of axle 104.In another implementation, if be constructed such that the pin and different axis (the x axle shown in not being) aligning that curet tip 114 is connected to axle 104, then curet tip 114 can center on disalignment (that is z axle) rotation.In another implementation, axle 104 can rotate or reverse, and causes the rotation at curet tip 114.
In an implementation, the work intubate is inserted into and makes the far-end of intubate be positioned in the place of waiting to make cavity in the patient's body.Curette system 100 is inserted in the intubate.During inserting by intubate, the required internal diameter (that is initial position) to minimize intubate is axially aimed at curet tip 114 with axle 104.In case the head 106 of Curette system 100 leaves intubate and be positioned to the position of waiting to make cavity in patient's body, curet tip 114 can rotate to extended position, and for example half-twist is to the position shown in Fig. 2.Curet tip 114 can be used as then that shovel digs or the scraping apparatus by the user by turn to, tractive and promotion Curette system 100 operate.
With reference to figure 3, shown the cutaway side sectional view of an implementation of the handle 102 of Curette system 100.As mentioned above, handle 102 comprises pedestal 103 and lever 108.Lever 108 can be centered around fulcrum 118 rotations in the proximal region of lever 108.In this implementation, the near-end 120 of lever comprises chamber 122, and this chamber is configured to receive the ball-and-socket joint 124 of the near-end that is attached to push rod 110.Around fulcrum 118, promptly make near-end 120 rotations of lever around x axle rotating lever 108.When lever 108 was closed up by user's extruding, the near-end 120 of lever turned clockwise, and causes ball-and-socket joint 124 translations, promptly is directed downwards along y.Ball-and-socket joint 124 causes push rod 110 along the translation of y direction along the translation of y direction.Ball-and-socket joint 124 is implementations of the connection between push rod 110 and the lever 108.This joint can have other structure.Usually, this joint should imitate the shape in chamber 122, and is promptly square, star, triangle etc.As above described with reference to figure 2, translation push rod 110 makes most advanced and sophisticated 114 rotations of curet.By attaching to outer shaft and be typed into flange 126 anti-throw-out lever 110 shifted laterallys (for example, along x shown in Fig. 3 and z direction) in the pedestal 103 of handle 102.
Ratchet mechanism can be included in the pedestal 103 of handle 102 so that one or more latched positions of lever 108 to be provided, and therefore one or more extended positions at curet tip 114 are provided.In an implementation, ratchet mechanism comprises slide link 130 and pallet 132.In an implementation, slide link 130 comprises that three grooves 134 and pallet 132 comprise at least one corresponding tooth 136, but other structure is possible.For example, non-exclusively, other structure can comprise ratchet and the gear train that is positioned at fulcrum, and its middle gear is along with lever rotation and ratchet prevent reverse rotation, unless break away from.Also can use the snap close and the pallet locking mechanism that for example are positioned at fulcrum 118.Mechanism shown in referring again to, each groove 134 is configured to receive the tooth 136 from pallet 132.Each groove 134 and tooth 136 can have as shown in the figure the inclined-plane so that tooth 136 with engagement with from wherein breaking away from.
With reference to figure 4, shown the side view of handle 102.In an implementation, labelling 138 can be included on the pedestal 103 of handle 102.Each labelling 138 can be corresponding to the latched position of lever 108, and the angle at indication curet tip 114 when lever 108 is in latched position.For example, lever 108 is shown as reset on the throne and represents that the angle at curet tip 114 is 0 °, so curet tip 114 is in initial position, axially aims at axle 104.The angle that next labelling 138 indications are 30 °, expression be when by moving to tooth 136 when making lever 108 be locked in this position in the predetermined groove (that is, next groove) 134, becomes about 30 ° angle at the curet most advanced and sophisticated 114 of extended position with the y axle.Next labelling 138 does not indicate, but can be corresponding to 60 ° angle, and labelling 138 can be corresponding to 90 ° angle at last.The user can extrusion lever 108 with shift lever between latched position 108 with advance slide link 130, make that the tooth 136 on the pallet 132 meshes with different grooves 134 in being included in slide link 130.In other implementation, can comprise more or less latched position of lever 108, it is corresponding to more or less extended position at curet tip 114.
Alternatively, most advanced and sophisticated 114 can be rotated and be not locked to one or more positions.For example, the fast hairdo extruding action of lever 108 can be used for rotating tip 114, and wherein release member 142 is in non-locking, rear positions (referring to Fig. 1 and 3) and prevents to mesh pallet 132.
Refer again to Fig. 3, handle 102 further comprises the extension spring 140 between the near-end of the end that is connected slide link 130 and pedestal 103.Extension spring 140 is pressed against groove 134 on the tooth (a plurality of tooth) 136 of pallet 132.Pedestal 103 further comprises release member 142, release member 142 operationally engages pallet 132 and discharges from slide link 130 to carry out pallet 132, makes that extension spring 140 can be with slide link 130 reorientations more near another selectable location of the corresponding initial position at the initial position of lever 108 and curet tip 114.When release member was in as shown in the figure non-moving position, flex member 141 can be pushed to pallet 132 with slide link 130 and engage.Connection element 135 is connected to pedestal 103 at the point of rotation 137 and 139 far-ends with lever 108.
Curette system 100 comprises and is designed to the safety component that prevents that curet head 106 from fractureing when for example being subjected to moment of torsion in the patient.Refer again to Fig. 3, axle 104 comprises safety groove 144.Safety groove 144 is designed to provide the atenuator region of axle 104, makes axle 104 will occur losing efficacy when being subjected to over-torque before curet head 106 loses efficacy.That is to say, littler in the safety groove 144 axle 104 required force rates power that can cause curet head 106 for example to lose efficacy that fractures by fractureing.Typically, the situation that can cause axle 104 to lose efficacy is that curet tip 114 is pressed against on the hard especially structure example such as bone, and this structure is not easy to be dug by most advanced and sophisticated 114 scrapings of curet or shovel.Axle 104 inefficacy provides the user to stop to move and from the withdraw indication of Curette system 100 of patient.If the user does not find immediately that axle 104 lost efficacy, the user can continue extrusion lever 108 and attempt to rotate curet tip 114.Because push rod 110 is connected to handle 102 by ball-and-socket joint 124, push rod 110 will be only along the translation of y direction, and will be not around the rotation of y axle.That is to say that rotary handle will can not make push rod 110 rotations, reason is only 122 internal rotation in the chamber of ball-and-socket joint 124.This structure has guaranteed to push away silk 112 and will not reel around push rod 110 and/or curet head 106, causes curet most advanced and sophisticated 114 to finish to be fixed on extended position, and therefore can not pass through cannula retracted.
