Detailed description of the invention
Please refer to Fig. 1 to Fig. 3, this utility model provides a kind of safety block device, especially, is a kind of customary risks block assembly being applicable to medical apparatus and instruments.
As shown in Figure 1, this utility model provides a kind of safety block device, comprises shell 1, above-mentioned safety block device comprises driving lever 2, above-mentioned driving lever 2 is rotatably installed in 1 li, above-mentioned shell, and above-mentioned driving lever 2 comprises the head 21 of driving lever 2, and a part for the head 21 of above-mentioned driving lever 2 is positioned at the outside of above-mentioned shell 1; Driving lever elastomeric element 3, one end of above-mentioned driving lever elastomeric element 3 is connected with above-mentioned driving lever 2, and the other end of above-mentioned driving lever elastomeric element 3 is connected with above-mentioned shell 1, the thrust rotated clockwise that above-mentioned driving lever elastomeric element 3 makes above-mentioned driving lever 2 be subject to as shown in Figure 1 all the time; Block 4, above-mentioned block 4 is slidably mounted on 1 li, above-mentioned shell; Block elastomeric element 5, one end of above-mentioned block elastomeric element 5 is connected with above-mentioned block 4, and the other end of above-mentioned block elastomeric element 5 is connected with above-mentioned shell 1, the thrust left that above-mentioned block elastomeric element 5 makes above-mentioned block 4 be subject to as shown in Figure 1 all the time; The primary importance as shown in Figure 1 of above-mentioned driving lever 2 makes above-mentioned safety block device be in closed condition, i.e. the original state of above-mentioned safety block device, and the head 21 of above-mentioned driving lever 2 can stop the motion of apparatus to move left and right, and plays the effect of insurance.As shown in Figure 2, the head 21 of above-mentioned driving lever 2 is chosen as the cylinder with certain length to the top view of above-mentioned driving lever 2.The second position as shown in Figure 3 of above-mentioned driving lever 2 makes above-mentioned safety block device be in open mode, namely the head 21 of above-mentioned driving lever 2 no longer stops the motion of apparatus to move left and right, and now above-mentioned block 4 makes above-mentioned driving lever 2 be in said second position as shown in Figure 3.Obviously, above-mentioned driving lever 2 and above-mentioned shell 1 also can adopt other modes of this area routine to be connected pivotly.Selectively, above-mentioned driving lever elastomeric element 3 is driving lever spring 3, and above-mentioned block elastomeric element 5 is stopper spring 5, and obviously, above-mentioned driving lever elastomeric element 3 and above-mentioned block elastomeric element 5 can also adopt other elastic types of this area routine.
This safety block device can be installed in medical apparatus and instruments, such as in hernia anastomat, when above-mentioned safety block device is in closed condition (now above-mentioned driving lever 2 is in primary importance as shown in Figure 1), the head 21 of above-mentioned driving lever 2 contacts with trigger, to stop the motion of trigger, thus apparatus cannot be operated.When insurance opened by needs, above-mentioned driving lever 2 is stirred the second position as shown in Figure 3 by primary importance as shown in Figure 1, so, the head 21 of above-mentioned driving lever 2 removes trigger position, reserves the mobile space of trigger, like this, trigger can movement automatically, thus apparatus can be pulled the trigger.Otherwise, mobile above-mentioned block 4, above-mentioned block 4 is made no longer to limit the position of above-mentioned driving lever 2, above-mentioned driving lever 2 resets to primary importance as shown in Figure 1 by said second position as shown in Figure 3 under the promotion of above-mentioned driving lever spring 3, above-mentioned safety block device is in closed condition, i.e. the original state of above-mentioned safety block device.
Owing to have employed said structure, point to clearly in operation, structure is simple, overall structure is small and exquisite, modularity by action for this utility model, may be used in various medical apparatus and instruments.
Selectively, a part for the head 21 of above-mentioned driving lever 2 is driven by external force and makes above-mentioned safety block device be in open mode as shown in Figure 3.
Selectively, above-mentioned driving lever spring 3 makes above-mentioned driving lever 2 be in primary importance as shown in Figure 1, is separated with above-mentioned block 4.
Selectively, above-mentioned block 4 makes above-mentioned driving lever 2 be in said second position as shown in Figure 3, and above-mentioned driving lever 2 compresses above-mentioned driving lever spring 3.
Selectively, above-mentioned block 4 is provided with the outside that protruding 41, above-mentioned protruding 41 reach above-mentioned shell 1, as shown in Figure 1.
Selectively, above-mentioned protruding 41 to be driven by external force above-mentioned driving lever 2 are separated with above-mentioned block 4, make above-mentioned safety block device be in closed condition as shown in Figure 1.
Selectively, the head 42 of above-mentioned block 4 is inclined-plane.
As shown in Figure 1, original state: the head 21 of above-mentioned driving lever 2 can stop the motion of apparatus to move left and right.
As shown in Figures 1 and 3, open safety block: the head 21 upwards boosting above-mentioned driving lever 2, above-mentioned driving lever 2 rotates counterclockwise, now above-mentioned driving lever spring 3 is by compression savings energy, the head 21 of above-mentioned driving lever 2 promotes the head 42 of above-mentioned block 4, above-mentioned block 4 is slided to the right, now above-mentioned stopper spring 5 is by compression savings energy, when above-mentioned driving lever 2 is positioned at the top of the head 42 of above-mentioned block 4, above-mentioned block 4 is promoted left by above-mentioned stopper spring 5, and the head 21 of above-mentioned driving lever 2 is ridden on above-mentioned block 4.Close safety block: the projection 41 promoting above-mentioned block 4 to the right, when above-mentioned block 4 is separated with the head 21 of above-mentioned driving lever 2, above-mentioned driving lever 2 is promoted by the energy that above-mentioned driving lever spring 3 self is put aside, and rotates clockwise the original state of getting back to as shown in Figure 1 downwards.
This utility model additionally provides a kind of medical apparatus and instruments, comprises above-mentioned safety block device.Such as, this medical apparatus and instruments can be hernia anastomat etc.In one embodiment, can the above-mentioned shell 1 of safety block device be fixed on the shell of this medical apparatus and instruments, in another embodiment, also can directly using the shell of the shell of this medical apparatus and instruments as above-mentioned safety block device.Then, the driving lever of safety block device is made to be connected with the trigger of medical apparatus and instruments.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
