Detailed Description
The present invention will be described in further detail with reference to the following detailed description of the preferred embodiments with reference to the accompanying drawings.
As shown in fig. 1-6, the puncture outfit pricking card holding and fixing device comprises a connecting seat 1, a first clamping piece 5, a second clamping piece 2, a wrench 3, a wrench screw 4, a pressure spring 8, a thimble 9, a spring-type microswitch 10, a torsion spring 11, a torsion spring shaft 12, a guide block 13 and a cover plate 14.
The connecting seat 1 is fixedly connected with a slave mobile mechanical arm of the minimally invasive surgery robot through a screw, so that the whole puncture outfit pricking card clamping and fixing device is fixed on the slave mobile mechanical arm. Second clamping piece 2 passes through screw and 1 fixed connection of connecting seat, and spanner 3 passes through holding screw to be fixed on spanner screw 4, and spanner screw 4 is connected with the screw hole on the second clamping piece 2, and spanner screw 4's tip can push up on first clamping piece 5. The puncture outfit poking card 6 is fixed in the poking card sleeve 7 through a set screw. The first jaw 5 and the second jaw 2 constitute a clip structure.
The torsion spring shaft 12 passes through the hole on the second clamping piece 2 and is fixedly installed on the second clamping piece 2, the torsion spring shaft 12 passes through two holes of the first clamping piece 5 to be rotationally connected with the first clamping piece 5 and the torsion spring shaft 12, the torsion spring 11 is sleeved on the torsion spring shaft 12, and two torsion spring arms of the torsion spring 11 are respectively contacted with the first clamping piece 5 and the second clamping piece 2, so that the torsion spring is in a compression state under the normal condition. When the first clamping piece 5 and the second clamping piece 2 are opened, the position of the second clamping piece 2 is not changed, and the position of the first clamping piece 5 is changed.
One end of the pressure spring 8 is propped against the thimble 9, and the other end of the pressure spring 8 is propped against the elastic sheet of the elastic sheet type microswitch 10. The guide block 13 is fixed on the second clamping piece 2 through screws, the thimble 9 is positioned in a guide hole of the guide block 13, the other end of the pressure spring 8 penetrates through a hole on the guide block 13 and is propped against a spring plate of the spring plate type microswitch 10, the spring plate type microswitch 10 is fixed on the second clamping piece 2 through screws, and the cover plate 14 is fixed on the guide block 13 through screws.
The working principle of the clamping and fixing device is as follows: firstly stab card 6 with the puncture ware and put into stabbing a cutting ferrule section of thick bamboo 7, find suitable position and fix with holding screw (holding screw passes the screw hole top of stabbing the side of the sleeve 7 of card on the puncture ware stabs the outer wall of card 6), then hold between the fingers the end of holding first clamping piece 5 and second clamping piece 2 and make first clamping piece 5 and second clamping piece 2 open, to stab cutting ferrule section of thick bamboo 7 and put into first clamping piece 5 and second clamping piece 2 in, stab the upper end of following the protruding part card at first clamping piece 5 and second clamping piece 2 on the sleeve 7 of card, guarantee to stab cutting ferrule section of thick bamboo 7 and can not two relative clamping piece lapse, rotatory spanner 3 again is with wrench screw 4 fastening on first clamping piece 5, two clamping pieces remain fixed, can not relative rotation. When stabbing cutting ferrule 7 and putting into the clip, stabbing cutting ferrule 7's side can extrude thimble 9, and thimble 9 can inwards shrink, and thimble 9 drives pressure spring 8 and presses on shell fragment formula micro-gap switch 10's shell fragment, causes shell fragment formula micro-gap switch 10 closure to switch on, and the control system of robot is given to shell fragment formula micro-gap switch 10 feedback signal, and control system discerns according to received signal, and this time puncture ware stabs 6 fixed completions of card. When the puncture outfit pokes the card 6 to be loosened or fall off (pokes the card sleeve 7 to be loosened or fall off), the thimble 9 pops out, and the elastic sheet type microswitch 10 is switched off.
The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those skilled in the art should understand it, without departing from the spirit of the present invention, they should also understand that other configurations of the components, driving devices and connecting means can be adopted without inventive design and structural modes and embodiments similar to the technical solution.
