Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of reset labor-saving structure of anastomat.
Background technology
Usually, when using linear anastomat to carry out identical to tissue, anastomosis procedure comprises two sections of closed action and shot action.First paragraph closed action needs positioning needle to release, thus is fixed in anastomotic stoma by tissue; Further, second segment closed action needs to make anastomotic component near nail supporting base with the grip tissue also identical gap of locking; Finally, press flexible handle percussion suturing nail, and suturing nail is worn out tissue and is against Closed forming on nail supporting base after being pulled the trigger, thus complete whole anastomosis procedure.Afterwards, need all component to comprise after positioning needle, anastomotic component and flexible handle all reset, just can exit anastomat.Therefore, under normal operation, an in the end step is only had to need to carry out reset operation, but, if need to adjust the number of the tissue entering identical gap in two sections of closed processes, now also need to carry out reset operation, so the reset operation of linear anastomat is divided into three sections.
Generally, existing linear anastomat often uses reset assembly to realize reset operation, reset assembly generally includes SR, reseting plate, lead, reset button is connected with reseting plate rear end, lead is arranged on tooth bar, reseting plate has the gathering sill of inclined downward backward, and lead is positioned at this gathering sill, tooth bar upper shell is provided with always with the insurance of tooth bar overlying contact, this insurance is pressed on tooth bar under spring torsion effect.In use, cocking, on trigger, propeller engages with tooth bar, promotes tooth bar and advances, and insurance is simultaneously subject to spring force, to the power that tooth bar one is downward, ensures to be in engagement between tooth bar and propeller; But because spring acts in insurance always, make insurance be pressed on tooth bar, when pulling back reset button and carrying out reset operation, resistance is comparatively large, and operator need to overcome larger restoring force and reset, inconvenient operation, and structure is stable not always.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is the reset labor-saving structure providing a kind of anastomat, can pull reset button easily when needs reset, and reduces the apparatus resistance resetted.
For achieving the above object and other relevant objects, this utility model provides a kind of reset labor-saving structure of anastomat, the tooth bar comprising housing and be arranged in housing and reset assembly, described reset assembly comprises the reseting plate being arranged on tooth bar side, the reset button being arranged on rack rear and the lead be arranged on tooth bar, described reset button is connected with reseting plate rear end, oriented groove low after high before described reseting plate offers, this gathering sill coordinates with lead, housing above described tooth bar is provided with hold-down mechanism, this hold-down mechanism is pressed on the upside of described tooth bar always, toggle mechanism is provided with between described reseting plate and hold-down mechanism, this toggle mechanism first end is connected with hold-down mechanism, second end is connected with reseting plate, when described reset button pulls reseting plate to move backward, toggle mechanism second end moves down, hold-down mechanism lifts by described toggle mechanism first end, hold-down mechanism is separated with on the upside of tooth bar.
Adopt said structure, existing resetting-mechanism improves, cocking, on trigger, propeller engage with tooth bar, promotes tooth bar and advances, while hold-down mechanism to the downward power of tooth bar one, be in engagement between guarantee tooth bar and propeller; When set, pull reset button, reset button drives reseting plate moved beneath backward, and reseting plate drives toggle mechanism, and hold-down mechanism and tooth bar are departed from, and reduces the resistance of replying; Be convenient to doctor's operation; Toggle mechanism wherein can be lever construction, can be also linkage etc., as long as can hold-down mechanism be driven to be separated with tooth bar when reseting plate moves to the back lower place.
As preferably: described hold-down mechanism comprises the support column be horizontally installed on housing and the clamping sleeve be enclosed within described support column, follower lever is provided with on the upside of described clamping sleeve, compression projection is provided with on the downside of clamping sleeve, on described clamping sleeve, cover has torsion spring, this one end is against on housing or tooth bar, the other end is against on the upside of compression projection or on front side of follower lever, described toggle mechanism is connected with follower lever, and described compression projection is pressed in described tooth bar upper side.
There is provided the thrust to tooth bar by torsion spring, when resetting, stirring follower lever by toggle mechanism, making it drive clamping sleeve to rotate, compress projection and leave tooth bar, discharged, thus reduce to reply resistance.
As preferably: described follower lever is on front side of clamping sleeve, and this follower lever is vertically arranged, and described compression projection is obliquely installed towards the clamping sleeve back lower place, and this compression projection lower surface is arcwall face.Compressing projection can be cam-like.
As preferably: described toggle mechanism is lever construction, comprise fulcrum shaft and stir bar, described fulcrum shaft is arranged on the housing above tooth bar, and it is parallel with described support column, described bar of stirring is enclosed within described fulcrum shaft, and rotate along described fulcrum shaft, this is stirred bar upper end and is connected with described follower lever, and lower end is connected with described reseting plate.
Stirred by the mode of lever, laborsaving, easy to operate.
As preferably: described fulcrum shaft is positioned at described back shaft front, described bar upper end edge of stirring laterally is bent into the first kink, this is stirred bar lower end edge and is laterally bent into the second kink, described first kink and the second bending part are in described the same side of stirring bar, described first kink is hooked on described follower lever, and described second kink is buckled in described reseting plate downside.
This structure, stirs bar and is obliquely installed, and when reset button pulls reseting plate to move down, the first kink hooks follower lever and rotates along back shaft, thus realizes compressing lifting of projection.
