The invention discloses a reset mechanism of a linear suturing and cutting instrument. The reset mechanism comprises a reset traction piece, a retreat pull rod connected with the reset traction piece, a rack movably connected with the retreat pull rod, and a reset sheet and a reset drag hook which are integrally molded, wherein the reset drag hook is perpendicularly and convexly arranged on the reset sheet, one end of a reset spring is hooked with the reset drag hook, the other end of the reset spring is hooked with a tension spring buckle of the linear suturing and cutting instrument, and the lower surface of the reset sheet is a surface contacting a longitudinal locking piece of the linear suturing and cutting instrument. The reset mechanism of the linear suturing and cutting instrument has the advantages that the reset sheet and the reset drag hook are integrally molded, thus being simple and reliable in structure, convenient to assemble and low in cost.
Description
Technical field
The present invention relates to a kind of Linear stapling cutter, especially a kind of resetting-mechanism of Linear stapling cutter, belongs to technical field of medical instruments.
Background technology
Current surgical operation is all toward the future development of endoscope operation formula, and for example U.S. Pat 7303107 has disclosed the Linear stapling cutter under a kind of endoscope operation formula.This Linear stapling cutter drives tooth bar to carry out seaming and cutting by ratchet, and resetting-mechanism when reset adopts independently part of two of reseting plate and reset drag hooks, and reset drag hook is connected on reseting plate by a connector, complex structure, and assembly difficulty is large.
The content that the present invention records this patent is quoted as prior art.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem, and a kind of resetting-mechanism of Linear stapling cutter simple in structure is provided.
Technical scheme of the present invention is:
A kind of resetting-mechanism of Linear stapling cutter, the rollback pull bar that comprises reset traction piece, be connected with described reset traction piece, the tooth bar that can be dynamically connected with described rollback pull bar, also comprise reseting plate and the reset drag hook of integrated molding, described reset drag hook is vertically convexly set on described reseting plate, there is one end of a reset tension spring to catch on described reset drag hook, the other end of described reset tension spring catches on the extension spring of described Linear stapling cutter and buckles, and the lower surface of described reseting plate is and the contact surface of the longitudinally only lock dog of described Linear stapling cutter.
Preferably, described extension spring button is arranged on the tooth bar of described Linear stapling cutter.
Preferably, described reset drag hook is located at the top of described tooth bar.
Preferably, on described reseting plate, connect and be provided with at least one reset guide groove, the side of described tooth bar convexes with at least one pilot pin, and described pilot pin extend in described reset guide groove.
Preferably, on described reseting plate, connect and be provided with opening, described rollback pull bar extend in the opening of described reseting plate.
Beneficial effect of the present invention is: by one-body molded, simple and reliable for structure, easy to assembly to reseting plate and reset drag hook, and cost.

Wherein: 1, reseting plate 2, reset drag hook 3, reset guide groove 4, reset tension spring; 5, opening; 6, extension spring button 7, pilot pin 8, longitudinally only lock dog 9, spring 10, rollback pull bar; 11, percussion handle; 12, ratchet; 13, reset traction piece 14, tooth bar.
The specific embodiment
Embodiment mono-: shown in Fig. 1 and Fig. 2, the invention provides a kind of resetting-mechanism of Linear stapling cutter, the rollback pull bar 10 that comprises reset traction piece 13, be connected with described reset traction piece, the tooth bar 14 that can be dynamically connected with described rollback pull bar, and the reseting plate 1 of integrated molding and reset drag hook 2.Described reset drag hook 2 is vertically convexly set on described reseting plate 1.The lower surface of described reseting plate 1 is and the contact surface of the longitudinally only lock dog 8 (shown in Fig. 3) of described Linear stapling cutter.Because reseting plate 1 and reset drag hook 2 are metal material, therefore can adopt the mode of stepping punching press to realize one-body molded.Certainly,, if reseting plate 1 and reset drag hook 2 are plastic material, can adopt integrated injection molding.
Have one end of a reset tension spring 4 to catch on described reset drag hook 2, the other end of described reset tension spring 4 catches on the extension spring button 6 of described Linear stapling cutter, and described extension spring button 6 is arranged on the tooth bar 14 of described Linear stapling cutter.Described reset drag hook 2 is located at the top of described tooth bar 14.
Shown in Fig. 3, Fig. 4, on described reseting plate 1, connect and be provided with at least one reset guide groove 3, the side of described tooth bar 14 convexes with at least one pilot pin 7, and described pilot pin 7 extend in described reset guide groove 3.Described reset guide groove 3 is oblique lower setting.On described reseting plate 1, connect and be provided with opening 5, the part of the rollback pull bar 10 of described Linear stapling cutter extend in described opening 5.
Operating process of the present invention once is simply described below.
As shown in Figure 3, the ratchet 12 of percussion on handle 11 drives tooth bar 14 to advance, now described reseting plate 1 high position in Fig. 3 all the time under the effect of reset tension spring 4, and described reseting plate 1 is not interfered tooth bar 14 and longitudinal lock dog 8 intermeshing only.Because a longitudinal only side of lock dog 8 is subject to the effect of spring 9, therefore it can stop tooth bar 14 rollbacks with engaging of tooth bar 14, and this hour rack 14 is in stopping lock status.
As shown in Figure 4, after Linear stapling cutter percussion, rollback pull bar 10 drives reseting plate 1 to move backward, and meanwhile under the effect of reset guide groove 3 and pilot pin 7, reseting plate 1 moves down again, reaches like this low level in Fig. 4.The active force that the lower surface of described reseting plate 1 forces described longitudinal only lock dog 8 to overcome spring 9 moves down, thereby the described lock dog 8 that longitudinally stops is thrown off with tooth bar 14, tooth bar 14 now is not subject to longitudinally only stopping of lock dog 8, pulls reset traction piece 13 can make the smooth rollback of tooth bar 14.
The present invention still has numerous embodiments, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the scope of protection of present invention.
