Detailed description of the invention
Please refer to Fig. 1 to Fig. 6, embodiments provide a kind of insurance bindiny mechanism of surgical clamp, comprising: insurance 10, connecting rod 20 and operating portion 30.Wherein, connecting rod 20 comprises sticking department 21, and insurance 10 realizes locking to connecting rod 20 or unblock by sticking department 21; Operating portion 30 is connected with connecting rod 20 pivotly by the first pivotal axis 40, and operating portion 30 arranges pivotly around the second pivotal axis 50 and moves along predefined paths with drive link 20.
In a preferred embodiment, the first pivotal axis 40 can be rivet.In a preferred embodiment, the second pivotal axis 50 can be pin.Obviously, the first pivotal axis 40 in the present invention and the second pivotal axis 50 are not limited to the concrete structure in above preferred embodiment, and other modes of this area routine all can be considered its equivalent way.
Please refer to Fig. 1 and Fig. 2, when insurance 10 is in closure state, connecting rod 20 is locked by the sticking department 21 of connecting rod 20 by insurance 10.Now, if hold operating portion 30 (as trigger etc.) to move along its predefined paths to carry out drivening rod 20 by operating portion 30 around the motion of the second pivotal axis 50, so because connecting rod 20 is insured 10 lockings, therefore, can not hold operating portion 30, operating portion 30 can not rotate around the second pivotal axis 50, and connecting rod 20 also can not by this predefined paths proper motion, thus, surgical clamp (as titanium clamp pincers) can not be excited to carry out clamp operation.
Please refer to Fig. 3 to Fig. 6, when insurance 10 is in open mode, connecting rod 20 is locked by the sticking department 21 of connecting rod 20 by insurance 10.Now, if hold operating portion 30, relieve locking to connecting rod 20 owing to insuring 10, therefore can hold operating portion 30 smoothly, and make it rotate around the second pivotal axis 50.So connecting rod 20, under the drive of operating portion 30, moves along this predefined paths, surgical clamp (as titanium clamp pincers) now can be normally excited to carry out clamp operation.
Owing to have employed said structure, when can need in operation process, open insurance, can normally excite to make surgical clamp (as titanium clamp pincers); After clamp, also conveniently can close insurance, can not be excited to make surgical clamp locked by mistake.Visible, the present invention can effectively prevent from exciting by mistake, prevents clip (as titanium folder etc.) the landing body cavity of surgical clamp, avoids potential danger.In addition, the present invention only needs, by can prevent from exciting to the operation of insurance by mistake, thus, to operate fast very convenient, can open and close insurance at any time.It is special that the present invention also has that structure is simple, cost is low.
Please refer to Fig. 1 to Fig. 6, preferably, insurance bindiny mechanism also comprises guide finger 60, and guide finger 60 coordinates connecting rod 20 is moved along predefined paths with the gathering sill 22 on connecting rod 20.During installation, one end of guide finger 60 is arranged in gathering sill 22, thus limits motion path when connecting rod 20 moves, so that the predefined paths that connecting rod 20 only can limit along gathering sill 22 and guide finger 60 moves.Certainly, also can adopt the guide frame of other this area routines in the present invention, as long as can realize making the connecting rod 20 in the present invention to move this purpose along predefined paths, all belong to the equivalent structure in the present invention.
Please refer to Fig. 1 to Fig. 4, preferably, connecting rod 20 also comprises: guide part 23 and linking arm 24.Wherein, guide part 23 comprises first end and the second end, and gathering sill 22 is arranged on guide part 23.Linking arm 24 is stretched out by the first end of guide part 23, and the free end of linking arm 24 is connected by the first pivotal axis 40 pivotly with operating portion 30, and sticking department 21 is connected with guide part 23.In the preferred embodiment, connecting rod 20 comprises guide part 23 and linking arm 24, and the width of guide part 23 is greater than the width of linking arm 24, like this, on the basis of proof strength, save the use doses of whole connecting rod 20, alleviate weight on the one hand, also reduce cost on the other hand.
Please refer to Fig. 1 to Fig. 4, preferably, guide part 23 comprises the side direction link position between the first end and the second end of guide part 23, and sticking department 21 is connected with side direction link position.More preferably, sticking department 21 comprises the protuberance 25 that the side to the second end extends, and forms the lock slots 26 locking for insurance 10 pairs of connecting rods 20 or unlock between protuberance 25 and guide part 23.Especially, the opening upwards of lock slots 26, protuberance 25 forms hook arrangement, to catch on insurance 10.Preferably, insurance 10 comprises securing rod 11, and securing rod 11, when insurance 10 closes, is stuck in lock slots 26, and securing rod 11 is when insurance 10 is opened, and go out of lock groove 26.
During operation insurance 10, the pivot axis of securing rod 11 in insurance 10 of insurance 10 can be made, to fall in this lock slots 26, or depart from this lock slots 26.In addition, the opening due to lock slots 26 is upwards, therefore, when closing insurance 10, the deadweight of securing rod 11 can be utilized to enter easily in lock slots 26, improve convenience and the agility of safe operation.
Preferably, as shown in Figures 1 to 4, gathering sill 22 is in the arc-shaped outstanding to the direction away from the second pivotal axis 50.Adopt the gathering sill 22 of arc-shaped, the motion of connecting rod 20 can be made more steady and smooth, comfortableness when improve operation and stability.
Preferably, as shown in Figures 1 to 4, in connecting rod 20 motor process, the first pivotal axis 40, second pivotal axis 50 and guide finger 60 are triangularly arranged all the time.Such as, first pivotal axis 40 and guide finger 60 can be fixed on the housing of surgical clamp, when connecting rod 20 moves, relative first pivotal axis 40 of second pivotal axis 50 and guide finger 60 move, but remain the position relationship of triangular arrangement between three, to guarantee the proper motion of connecting rod 20, prevent stuck and problem that is that can not move.
Please refer to Fig. 1 to Fig. 6, present invention also offers a kind of surgical clamp, comprise above-mentioned insurance bindiny mechanism.Preferably, surgical clamp is burst titanium clip.Such as, the operating portion 30 of insurance bindiny mechanism can be the trigger of surgical clamp, and the first pivotal axis 40 and guide finger 60 can be fixed on the housing of surgical clamp.
When needs carry out clamp operation, make insurance 10 be in open mode, thus explain the locking to the connecting rod 20 in insurance bindiny mechanism, like this, namely by the operation to operating portion 30, realize normal clamp.After clamp, in order to prevent exciting by mistake, insurance 10 is placed in closure state, thus connecting rod 20 is locked, like this, even if touched operating portion 30 because of carelessness due to maloperation, also clamp can not have been excited, thus, but effectively prevent maloperation from making the landing body cavitys such as titanium folder, avoid potential danger.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
