Abstract
The utility model discloses a double speed adjusting device for the alimentary canal anastomat, comprising a anastomat body, the knob body which is revolving connected to the anastomat body, the screw which is connected to the knob body through thread. The screw is inserted into the inner cavity of the anastomat body. The front part of the screw is connected to the center rod in the inner cavity of the anastomat body. The screw is provided with a first thread section and a second thread which are connected each other. The pitch of the first thread section is bigger than that of the second thread section. The distance between the nail bin and the nail jacking seat is quickly reduced, the second thread section relatively slides to the knob body, so the moving speed of the screw during the turning of the knob is slowed down which benefits the operation process of the alimentary canal.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of digestive tract stapler.
Background technology
In the prior art, it all is one velocity that the center-pole of digestive tract stapler is regulated, the knob body that it comprises the anastomat body, be connected rotationally with described anastomat body, the screw rod that threadably is connected with described knob body, this screw rod is inserted in the inner chamber of described anastomat body, and the front portion of this screw rod is connected with center-pole in the anastomat chamber body.When both forward and reverse directions turning knob body, can pull to nail bin thereby drive nail supporting base so that the screw rod fore-and-aft direction moves.Present screw rod all is a constant lead screw, and lead angle is not more than 10 degree.Therefore in order to make nail supporting base pull to nail bin, knob need rotate 20 multi-turns could make the screw rod of fine pitch further nail bin and nail supporting base, very trouble.And the screw rod of coarse pitch belongs to the structure that furthers fast, doctors do not welcome yet, because when nail supporting base and nail bin are soon approaching, doctors need constantly to confirm to have its hetero-organization incarceration of denying between nail supporting base and nail bin, at this moment need the extremely slow speed operation nail supporting base and the closing speed of nail bin, therefore the existing mechanism that furthers soon, slowly all can not satisfy the requirement of operation.
Summary of the invention
The purpose of this utility model is to provide a kind of double speed adjusting device of digestive tract stapler, when distance is far away between nail supporting base and nail bin, can further fast both distance, between nail supporting base and nail bin during close together, both distance more slowly can further.
The technical solution of the utility model is: a kind of double speed adjusting device of digestive tract stapler, the knob body that comprises the anastomat body, is connected rotationally with described anastomat body, the screw rod that threadably is connected with described knob body, this screw rod is inserted in the inner chamber of described anastomat body, the front portion of this screw rod is connected with center-pole in the anastomat chamber body, described screw rod has the first continuous thread segment and second thread segment, and the pitch of described first thread segment is greater than the pitch of second thread segment.
This utility model compared with prior art has following advantage:
Since the pitch difference of two thread segments, the distance of therefore can further fast nail bin and nail supporting base, slide by second thread segment is relative with the knob body in the back of furthering, and the translational speed of screw rod is slack-off when making turning knob, helps gastral operation and carries out.

The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 3, a kind of double speed adjusting device of digestive tract stapler, the knob body 6 that comprises anastomat body 7, is connected rotationally with described anastomat body 7, the screw rod 5 that threadably is connected with described knob body 6, this screw rod 5 is inserted in the inner chamber of described anastomat body 7, the front portion of this screw rod 5 is connected with center-pole 12 in anastomat body 7 inner chambers, described screw rod 5 has the first continuous thread segment 9 and second thread segment 10, and the pitch of described first thread segment 9 is greater than the pitch of second thread segment 10.Described knob body 6 is provided with projection 8, and this projection 8 is inserted in the thread groove of screw rod 5, and projection 8 plays the effect of nut, makes that screw rod 5 can move axially when knob body 6 rotated.Described second thread segment 10 is positioned at the front portion of screw rod 5, and described first thread segment 9 is positioned at the rear portion of first thread segment 10.Also has the 3rd thread segment 15 on the screw rod 5 at the rear portion of described first thread segment 9, the rear portion of described knob body 6 also has inner nut 11, when this inner nut 11 was threaded mutually with the 3rd thread segment 15, described projection 8 was inserted in the thread groove of first thread segment 10.When this utility model enters low speed segment, promptly the distance of nail bin and nail supporting base draw nearer after, forward first thread segment 10 of screw rod 5 and the 3rd thread segment 15 at screw rod rear portion can both match with knob body 6, make screw rod 5 can not rock.
