Push rod, the push rod that coincide perpendicularly is fixed on fixed part with the identical push rod of lifting with anastomat body axial direction, is lifted
The end of push-rod piston bar is fixed with closure, and the push-rod piston bar that coincide is slidably matched with closure, and its end is provided with one and leads to
Hole, is provided with the locking push rod that its piston rod can be slidably matched with through hole in the closure, the handle portion includes fixed handss
Handle, and control coincide push rod, lifting coincide push rod and locking push rod extended and shrinkage operation control knob.
Further, the closure is provided with sliding rib, the fixed part in the near-end central region coordinated with fixed part
On be correspondingly arranged on sliding rib groove.
Further, the closure is provided with backgauge rib, the fixation in the distal end central region coordinated with fixed part
Backgauge rib groove is correspondingly arranged in portion.
Further, the backgauge rib is in inverted cone shape.
Further, identical push rod, the identical push rod of lifting and locking push rod are multi-section combined.
The beneficial effects of the present invention is：
The present invention makes closure in closed procedure by the combination application of the push rod that coincide, the identical push rod of lifting and locking push rod
When, all the time with fixed part keeping parallelism, it is ensured that optional position and gmatjpdumamicss uniformity on fixed part, it is to avoid intestinal body is subject to not
Uniform extruding force skids off fixed part and cannot complete to coincide and the occurrence of cutting operation.
Other advantages of the present invention, target and feature will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The present invention target and other advantages can be realized by description below and
Obtain.

Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in figures 1-8, the hysteroscope cutting closer of the present embodiment, including anastomat body 1, anastomat two ends set respectively
Put handle portion and cutting part, cutting part includes the fixed part 2 that self-fitting device body extends and can be opened and be closed
Closure 3, particularly, the present embodiment also includes coincideing push rod 4 and lifts the push rod 5 that coincide, and coincide push rod and the identical push rod of lifting
Closure is arranged in parallel to each other with fixed part between the two, as illustrated, the push rod that coincide is located at distal end, the identical push rod of lifting
It is proximally-located, meanwhile, the push rod that coincide is perpendicular with anastomat body axial direction with the identical push rod of lifting, and its Spin Control
Part is fixed on fixed part, and the end for lifting push-rod piston bar is fixed with closure, and the push-rod piston bar that coincide is slided with closure
Dynamic to coordinate, its end is provided with a through hole, the locking push rod 6 that its piston rod can be slidably matched with through hole is provided with closure,
In the piston rod insertion through hole of locking push rod 6, the piston rod of the push rod that coincide is locked, and then together with the identical push rod of lifting
Anastomosis procedure is completed, because identical push rod and the identical push rod of lifting be arranged in parallel, and both are arranged respectively in distal end and near-end, because
This, can produce the identical power of uniformity in the length range of closure, improve match result；Meanwhile, the present embodiment
Handle portion includes fixed handle 11, and the identical push rod of control, the identical push rod of lifting and locking push rod are extended and shunk behaviour
The control knob 12 of work, by button control, is easy to operate, succinct, laborsaving, it is possible to reduce prior art takes manual operations
Inconvenience with it is loaded down with trivial details.
In the present embodiment, the push rod that coincide, the identical push rod of lifting and locking push rod are multi-section combined structure, can be used less
Realize longer elongation range in space.
In the present embodiment, closure is provided with sliding rib 7 in the near-end central region coordinated with fixed part, right on fixed part
Sliding rib groove 8 should be provided with, by the cooperation of sliding rib and sliding rib groove, on the one hand the movement of closer can be oriented to, be improved
The accuracy and reliability of anastomosis procedure, on the other hand can also reduce contact area, reduce coefficient of friction and kinetic damping.
In the present embodiment, closure is provided with backgauge rib 9 in the distal end central region coordinated with fixed part, on fixed part
Backgauge rib groove 10 is correspondingly arranged on, backgauge rib is arranged in inverted cone shape, as shown in fig. 7, in identical early stage, the head elder generation of backgauge rib
Contact with intestinal body, with identical continuation, the back taper of backgauge rib is formed to intestinal body and extruded, and forces it to move toward inner chamber, and then is kept away
Exempt from intestinal body and skid off fixed part, further improve the reliability of operation.
Specific operation process：
1) lift the push rod that coincide to rise, closure is moved into open state, as shown in Figure 2；
2) closer is pushed ahead, is intended to identical intestinal body and penetrates between closure and fixed part；
3) push rod that coincide rises, and its piston rod is penetrated in closure,
4) push rod work is locked, its piston rod is penetrated and is locked in the piston rod of identical push rod, as shown in Figure 3；
5) identical push rod, the identical push rod of lifting are return simultaneously, complete anastomosis procedure, as shown in Figure 1；
6) lock push rod to return, overall process is completed.
The present invention makes closure in closed procedure by the combination application of the push rod that coincide, the identical push rod of lifting and locking push rod
When, all the time with fixed part keeping parallelism, it is ensured that optional position and gmatjpdumamicss uniformity on fixed part, it is to avoid intestinal body is subject to not
Uniform extruding force skids off fixed part and cannot complete to coincide and the occurrence of cutting operation.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate technical scheme, although logical
Cross above preferred embodiment to be described in detail the present invention, it is to be understood by those skilled in the art that can be
In form and in details various changes are made to it, without departing from claims of the present invention limited range.
