Language is described.
In embodiments of the present invention, Medical stapler of the invention is done using hysteroscope surgical incision anastomat as example
It is specific to illustrate, but it should be stated that, the skill spirit involved in embodiment disclosed below can be utilized alternatively
Onto the stapler of other forms.
Medical stapler is used to for multiple suturing nails being applied to the physiological tissue of human body, while accordingly to physiological tissue
Implement cutting.As shown in Figure 1, an embodiment of the present invention provides a kind of Medical stapler, specifically, Medical stapler is straight
Line style stapler.Medical stapler include instrument body (not shown), connect instrument body percussion handle (not shown) and can
Releasably it is connected to the nail bin groupware 10 of instrument body.Specifically, percussion handle is pivotally connected to instrument body by pivot, nail
Storehouse component 10 is connected to the distal end of instrument body.
It is provided in instrument body push rod (not shown), push rod can be outer with respect to instrument body under the action of percussion handle
Shell is mobile.
As shown in Fig. 2 to Fig. 9, nail bin groupware 10 includes nail bin connector 12 and jaw device 14.Nail bin connector 12 wraps
Include connected with outer casing 19, shell 16 and the pull rod 18 being movably disposed in shell 16 along longitudinally, shell 16 with 18, pull rod
In the inside of connected with outer casing 19；Jaw device 14 is located at the distal end of nail bin connector 12, and pull rod 18 is connected to jaw device 14, and
Pull rod 18 can operatively be promoted jaw device 14 to swing relative to shell 16 to opposite both direction.By pulling or pushing
Pull rod 18 can make jaw device 14 turn an angle relative to nail bin connector 12 to different directions, to adapt to multi-angle
Cut anastomosis operation.
Specifically, pull rod 18 is equipped with groove 20, shell 16 is equipped with protrusion 22, and is equipped with the partial shell 16 of protrusion 22
Place is designed to the curved bending in direction far from pull rod 18, when pull rod 18 is in release conditions, groove 20 and protrusion 22
Matched, jaw device 14 is in original state relative to shell 16, and jaw device 14 is not swung relative to shell 16 at this time.When
When pull rod 18 is pulled or is pushed, groove 20 is separated with protrusion 22, and jaw device 14 is relative to shell 16 respectively to opposite
Both direction swing certain angle.As shown in Fig. 6 to 7, when pull rod 18 is by the pulling force that pulling force backward is proximally, pull rod
18 swings moved back to drive the direction thereto of jaw device 14.
In this preferred embodiment, when jaw device 14 is in original state, designed at the partial shell 16 equipped with protrusion 22
At predeformation bending, and shell 16 is rigid structure, will not deformation occurs, the protrusion 22 on shell 16 is fallen on pull rod 18
In groove 20, so that pull rod 18 is positioned at original state.And when pull rod 18 is pulled or is pushed, jaw device 14 is opposite
Certain angle is swung to opposite both direction respectively in shell 16, the groove 20 on pull rod 18 is separated with protrusion 22, due to
The bending of shell 16 by bit space presence, and rigidity 16 bending of shell at do not deform, in protrusion 22 and groove
20 when being mutually disengaged, since protrusion 22 is set to bending by bit space, even if being rigid at the bending of shell 16, still
Very big resist force will not be caused to pull rod 18, therefore pull rod 18 can only generate very small deformation, do not influence clamp dress
The swing angle for setting 14 enables jaw device 14 more accurately to reach predetermined angle.
Preferably, curved portion 24, the arc core of curved portion 24 and protrusion 22 are bent at the partial shell 16 equipped with protrusion 22
Positioned at the same side of curved portion 24, in this way, curved portion 24 can provide certain bit space that allows for protrusion 22.Certainly, it is equipped with convex
Other shapes can also be bent at the partial shell 16 in portion 22, as long as providing centainly when pull rod 18 is by movement to protrusion 22
Allow bit space.
Protrusion 22 has the smooth edge for facilitating access for and deviating from groove 20.In addition, the cross section of groove 20 is set as round
Shape.When pull rod 18 is pulled or pushes, it is only necessary to apply lesser power, so that it may deviate from protrusion 22 from groove 20, more
Convenient for operation.In addition, the end that groove 20 enters or deviates from for protrusion 22 is provided with guiding curved surface, so that protrusion 22 is more
Facilitate access for or deviate from groove 20.
Further, protrusion 22 is set as spherical.The centre of sphere of protrusion 22 and the arc core of curved portion 24 define first straight line,
First straight line is perpendicular to longitudinally.That is, protrusion 22 is set at the middle position of curved portion 24.So set,
In the case that 22 size of protrusion is certain, in the case that the radian and radius of curved portion 24 are certain, curved portion 24 is mentioned to protrusion 22
What is supplied makes bit space maximum.
Pull rod 18 is set as the flake extended along longitudinally, and pull rod 18 has first surface and opposite with first surface
Second surface, groove 20 is set as extending to the through slot of second surface from first surface.Specific in the present embodiment, groove 20
It is provided in round through slot, and the periphery diameter of protrusion 22 and 24 joint of curved portion is greater than the internal diameter of groove 20.
In this preferred embodiment, jaw device 14 include open/closed first clamp 26 and the second clamp 28, first
Clamp 26 is connected nail bin frame 30 and nail bin 32, and the second clamp 28 is nail anvil.
It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say
As a whole, the technical solution in each embodiment may also be suitably combined to form those skilled in the art can for bright book
With the other embodiments of understanding.
Tool of the series of detailed descriptions listed above only for the feasible embodiment of the utility model
Body explanation, they are all without departing from made by the utility model skill spirit not to limit the protection scope of the utility model
Equivalent implementations or change should be included within the scope of protection of this utility model.
