Specific embodiment is used to further illustrating but being not limited to the present invention below, and example below is only that the present invention is a kind of
It is preferably carried out mode.
Specific embodiment
Fig. 1 to Figure 11 is refer to, the invention provides a kind of safety, especially, are that one kind is applied to medical apparatus and instruments
Customary risks device.
The safety include：Support 1, is provided with the first guide part 2 on support 1, the first guide part 2 includes first
Put and the second position；Pin 3, is pivotably connected with support 1, and the second guide part 4 is provided with pin 3, and pin 3 has to be opened
Position and closed position；Dragging element 5, dragging element 5 passes through the first guide part 2 and the second guide part 4 will be support 1 movable with pin 3
Couple together；The switching between the first location and the second location of dragging element 5 drive 3 opposite brackets 1 of pin open position with
Switch between closed position.For example, in one embodiment, dragging element 5 be dead man, for example, driving lever can be a plastics or
The axle class of the Arbitrary Shape Cross Section of metal.Preferably, safety also include that rotating shaft 7, support 1 and pin 3 can pivots by rotating shaft 7
Turn ground connection, it is clear that the other modes that support 1 and pin 3 can also adopt this area conventional are pivotably connected.It is excellent at one
In the embodiment of choosing, support 1 can be a plastics or metal parts.
Refer to Fig. 5 to 6, and Figure 10 to 11, the safety are mountable in medical apparatus and instruments, such as in hernia anastomat
In, when pin 3 is located at closed position (now dragging element 5 is in first position), which is contacted with trigger, to prevent the fortune of trigger
It is dynamic, so that apparatus cannot be operated.When needing to open insurance, dragging element 5 is stirred into the second position by first position, in
It is that, under the driving of dragging element 5, pin 3 turns to open position by closed position around with its rotation axis with support 1, from
And make pin 3 remove trigger position, and the mobile space of trigger is reserved, so, trigger can be automatically moved, so that apparatus can be with
Percussion.Conversely, when dragging element 5 is stirred to first position by the second position, under the driving of dragging element 5, pin 3 again can be around
Closed position is turned to by open position with its rotation axis with support 1.
As a result of said structure, it is little that clear and definite, simple structure, overall structure are pointed in action in operation of the invention
Ingeniously, modularity, can be used in various medical apparatus and instruments.
In a preferred embodiment, the first guide part 2 includes the first gathering sill, and the second guide part 4 includes that second leads
To groove, dragging element 5 is located in the first gathering sill and the second gathering sill.So, pin 3 can be limited by the first gathering sill
Rotation path and scope, and passing through the second gathering sill can make dragging element 5 in the extension of pin 3 in the rotation process of pin 3
Position on direction is adapted with the rotation path and scope.
Preferably, the close pin 3 of the first gathering sill forms oriented on the inwall of the side of the rotation axiss of support 1
The protuberance 6 that the inside of one gathering sill projects, first position are located at the first side of protuberance 6, and the second position is located at protuberance 6
Second side.Using the protuberance 6, can prevent dragging element 5 from unexpected motion occurring between the first position and the second position, from
And can the unexpected switching between open and closed positions of anti-gear-stopping bar 3, so as to improve the reliability of safety.
Certainly, the safety in the present invention can also using this area others technological means, carry out anti-gear-stopping bar 3 in open position and
Unexpected switching between closed position, it is not limited to the mode of the present embodiment.
In one embodiment, support 1 takes the shape of the letter U, and pin 3 is arranged in the opening of the U-shaped of support 1.For example, pin 3
One end can be stretched out outside the opening of U-shaped, to realize the control to trigger.
In one embodiment, safety also include flexible member 8, and one end of flexible member 8 is connected with rotating shaft 7, bullet
The other end of property element 8 is connected with dragging element 5.For example, flexible member 8 can be spring etc..In one embodiment, rotating shaft 7
With the groove 9 for elastic elements is provided with dragging element 5.In the presence of flexible member 8, dragging element 5 can be made on edge
During first gathering sill is moved, the side of the first gathering sill is fitted in all the time.Especially, when flexible member 8 crosses protrusion
During portion 6, dragging element 5 is made reliably to be placed in first position or second position, in case gear-stopping bar 3 is in open position and closed position
Between unexpected switching, so as to improve the reliability of safety.So, when acting on without external force, flexible member is in drawing
Tight state, driving lever and pin can be maintained at current location.Obviously, in the present invention can also other conventional means of this area, come
Realize that the position to dragging element 5 locks, for example, using extra locking device etc..
In the embodiment shown in Fig. 1 to 11, safety include two pins 3, shape after one end connection of two pins 3
Into U-shaped structure, flexible member 8 is arranged between two pins 3.In an embodiment (not shown), the both sides difference of pin 3
It is provided with a flexible member 8.Now, the number of pin 3 can also be one.
Preferably, dragging element 5 is arranged on the opening around the U-shaped closer or far from support 1 of the rotation axiss of support 1 of pin 3
The side of mouth.For example, in the embodiment of Fig. 1 to 6, dragging element 5 is arranged on pin 3 and props up around the close of the rotation axiss of support 1
The side of the opening of the U-shaped of frame 1；And in the embodiment of Fig. 7 to Figure 11, dragging element 5 is arranged on rotation of the pin 3 around support 1
The side of the opening of the U-shaped away from support 1 of axis.
Safety in the present invention have two states, are respectively used to open and close insurance.For example, can by Fig. 5 and
In Figure 10, the position that dragging element 5 is located is when as closed position；And in Fig. 6 and 11, the position that dragging element 5 is located is beaten when conduct
Open position.
Present invention also offers a kind of medical apparatus and instruments, including above-mentioned safety.For example, the medical apparatus and instruments can be hernia
Anastomat etc..In one embodiment, the support of safety can be fixed on the shell of the medical apparatus and instruments, at another
In embodiment, also can directly using the shell of the medical apparatus and instruments as safety support.Then, make the pin of safety with
The trigger of medical apparatus and instruments is connected.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
