Abstract
Disclosed is a surgical round tube type stapler with a quick adjustment device. Different from the method for adjusting a screw by using an adjusting button directly in prior art, double springs are disposed in a push adjustment device. Single-speed adjustment is modified to two-speed adjustment to separate combination among parts of a stapler head to two stages of coarse adjustment and trimming adjustment. Closing of nail bin component and nail-anvil component can be realized quickly based on accurate positioning and the operation time is shortened greatly. The disclosed stapler has a simple structure and will have a good application in surgical instrument domain.
Description
Technical field
This utility model relates to the Binding Instrument that surgical operation uses, and is in particular the circular pipe type binding device for surgery, and especially a kind of circular pipe type binding device for surgery that is provided with quick adjustment mechanism belongs to technical field of medical instruments.
Technical background
The circular pipe type Binding Instrument that uses for surgical operation in the prior art, it advances governor motion to be: the end at the Binding Instrument body is provided with adjusting knob, adjusting knob directly links to each other with screw mandrel with thread forms, screw mandrel again be positioned at the Binding Instrument chamber body in anvil pull rod be connected.When rotating adjusting knob forward or backwards, screw mandrel is moved forward and backward, and then move by the nail-anvil assembly of anvil pull rod drive Binding Instrument front end, realize the clutch between the crimp head parts, thereby guarantee carrying out smoothly of whole surgical procedures.In present existing this class Binding Instrument, that uses is equidistant screw rod, lead angle is no more than 10 degree, the advance and retreat of its anvil pull rod are one velocity, low speed is regulated, so, in order to realize the clutch between crimp head nail-anvil assembly and the nail bin groupware, adjusting knob need be rotated 20 multi-turns, the muscle power that this has not only greatly consumed the doctor has also prolonged operating time, and is unfavorable to the whole surgery process.
Summary of the invention
The purpose of this utility model is to overcome the prior art above shortcomings, provides a kind of and is easy to process, the surgery that is provided with quick adjustment mechanism pipe Binding Instrument easy to use.
The purpose of this utility model realizes by following technical solution:
Be provided with the surgery pipe Binding Instrument of quick adjustment mechanism, comprise Binding Instrument body, crimp head, firing lock and propelling governor motion, firing lock comprises handle, ejector pin bar and pushing slice of nail, advance governor motion to comprise adjusting knob and screw mandrel, it is characterized in that: the front end of described adjusting knob is a cavity structure, be provided with buffer spring in the cavity, the front end inboard of cavity is provided with projection, and the rear end of cavity, the body interior of stretching to adjusting knob also further are provided with female thread; The end of described screw mandrel is provided with external screw thread, and this external screw thread [10] matches with the female thread of adjusting knob inside, is provided with projection in the surface of screw mandrel, externally threaded front side, is provided with shift spring between the inside block of this projection and Binding Instrument body.
The purpose of this utility model also can further realize by following technical measures:
The above-mentioned surgery that is provided with quick adjustment mechanism pipe Binding Instrument, wherein, adjusting knob is rotatably connected by external screw thread and female thread with the tail end of Binding Instrument body.
The above-mentioned surgery that is provided with quick adjustment mechanism pipe Binding Instrument, wherein, the projection that described adjusting knob and screw mandrel are provided with above respectively is the arc bump of two symmetry arrangement, every maximum arc length is less than 90 °.
The above-mentioned surgery that is provided with quick adjustment mechanism pipe Binding Instrument, wherein, the female thread on female thread on the adjusting knob and external screw thread, the Binding Instrument body, the external screw thread above the screw mandrel, its pitch all equates.
This utility model pin is changed the way of directly regulating screw mandrel in the prior art with adjusting knob, by advancing governor motion inside that shift spring and buffering spring are set, improved the serviceability of surgery with the tubular Binding Instrument, its maximum characteristics are to change the single speed adjusting of prior art into the two-stage adjusting, make the combination between the crimp head parts be divided into coarse adjustment and two stages of fine setting, guaranteeing to realize drawing close between nail bin groupware and the nail-anvil assembly apace on the pinpoint basis, shortened operating time greatly.This utility model structure is simple and clear, has good application prospects at surgery with medical instruments field.
Description of drawings
Below in conjunction with Figure of description technical solutions of the utility model are elaborated.Wherein:
Fig. 1 is the overall structure figure of surgery with the pipe Binding Instrument;
Fig. 2 is the structural representation that this utility model advances governor motion.
Among the figure, 1-Binding Instrument body, 2-adjusting knob, 3-screw mandrel, 4-shift spring, 5-buffer spring, 6-female thread, 7-external screw thread, 8-projection, 9-projection, 10-external screw thread, 11-female thread.
The specific embodiment
As Fig. 1～Fig. 2, surgery tubular Binding Instrument, its overall structure comprises Binding Instrument body 1, crimp head, firing lock and propelling governor motion, firing lock comprises handle, ejector pin bar and pushing slice of nail, advance governor motion to comprise adjusting knob 2 and screw mandrel 3, adjusting knob 2 is rotatably connected by external screw thread 7 and female thread 6 with the tail end of Binding Instrument body 1, screw mandrel 3 is connected with anvil pull rod in being positioned at the Binding Instrument chamber body, by rotation adjusting knob 2, screw mandrel 3 is moved forward and backward, and then it is flexible to drive anvil pull rod, realizes the nail-anvil assembly of crimp head part and the clutch between the nail bin groupware.
In technical solutions of the utility model, the front end of adjusting knob 2 is a cavity structure, is provided with buffer spring 5 in the cavity, and the front end inboard of cavity is provided with projection 9, and the rear end of cavity, the body interior of stretching to adjusting knob 2 also further are provided with female thread 11.The end of screw mandrel 3 is provided with external screw thread 10, and external screw thread 10 matches with female thread 11, is provided with projection 8 in the surface of screw mandrel 3, the front side of external screw thread 10, is provided with shift spring 4 between the inside block of projection 8 and Binding Instrument body 1.
Under the original state, projection 8 is against the outside of projection 9, and shift spring 4 is in compressive state.During use, rotate adjusting knob 2, projection 9 and the projection on the screw mandrel 38 on the adjusting knob 2 break away from, under the effect of shift spring 4, screw mandrel 3 moves rapidly backward, buffer spring 5 can play cushioning effect in the moving process, touches mutually with the position, female thread 11 place of adjusting knob 2 until the end of screw mandrel 3.Be rotated further adjusting knob 2, the external screw thread 10 on screw mandrel 3 surfaces screws in the middle of the female thread 11 of adjusting knob 2, realizes fine setting.Like this, the displacement of screw mandrel 3 is divided into fast mediation and transfers two stages slowly in the whole operation process, thereby plays the better implement effect.
In the said structure, optimized technical scheme is: adjusting knob 2 respectively is the arc bump of two symmetry arrangement with the projection 8 and 9 that screw mandrel 3 is provided with above, and every maximum arc length is less than 90 °; And internal and external threads 6 and 7,11 and 10 pitch all equate.
Except that above-mentioned preferred embodiment, this utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of this utility model.
