Description

Linear anastomat

Technical field

This utility model relates to a kind of linear anastomat, belongs to technical field of medical instruments.

Background technology

Anastomat, the equipment of the alternative traditional-handwork stitching of promptly medically using.Surgical linear type anastomat requires nail bin groupware disposablely to use, and the nail bin groupware of therefore finishing the percussion operation just can not be repeated percussion, just can carry out sew application after having only again the new nail bin groupware of correct installation.

The critical piece of existing linear anastomat is nail supporting base, nail bin groupware, assembly clamping plate, push pedal, safety block and nail supporting base clamping plate, wherein safety block is fixed on the assembly clamping plate by pin, safety block travels forward with the assembly clamping plate, finish and clamp action, at this moment, if nail bin groupware does not insert or be equipped with the nail bin groupware that had hit, safety block pops up, its elbow part hooks push pedal, stops push pedal to do the ejector pin action forward.When reinstalling new nail bin groupware, safety block is depressed, and its elbow part breaks away from push pedal, and the nail pushing plate of this moment can be finished the ejector pin action after anastomat clamps, and push pedal is moved backward after finishing, and safety block resets and hooks nail pushing plate again.After nail bin groupware uses,, can not again safety block be depressed, so anastomat can not repeat percussion because pushing slice of nail is forward.Though this scheme has error-disable function, can not pinpoint the problems at the very start, after nail bin groupware uses, because safety block is connected on the assembly clamping plate, push pedal can also be done and clamp action, just can not do the ejector pin action, on operating-table, the time is valuable; If the doctor is put in the anastomat opening and after clamping, finds that just nail bin is empty by the time, and then changes nail bin, then waste a lot of times to tissue.

The utility model content

The technical problems to be solved in the utility model is: in order to overcome the defective that exists in the background technology, provide a kind of and can not repeat percussion, push pedal just can clamp the linear anastomat that moves with ejector pin after only reinstalling new nail bin groupware, the doctor can be pinpointed the problems at the very start, save operating time.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of linear anastomat, comprise body, and be arranged on nail supporting base on the described body, nail bin groupware and the push pedal that is used to promote described nail bin groupware, described nail supporting base is installed in described body foremost by the nail supporting base clamping plate, described push pedal is slidingly arranged on the described body, also be provided with the assembly clamping plate that are used for fixing described nail bin groupware in this push pedal, described nail bin groupware and nail supporting base are oppositely arranged and are installed in the push pedal front end by the assembly clamping plate, between nail supporting base and push pedal, rotate on the described nail supporting base clamping plate and be provided with a safety block, described safety block has two operating positions at least, under first operating position, described safety block pops up and blocks described push pedal, under second operating position, described safety block breaks away from described push pedal.Further, described safety block front end has a hook portion, and under first operating position, the hook portion of described safety block is hooked described push pedal front end, adopts hook portion can hook push pedal more reliably.

Further, described safety block and described nail supporting base clamping plate pin joint adopt this connected mode, and safety block can rotate.

Beneficial effect: this utility model has solved the defective that exists in the background technology, if do not reinstall new nail bin groupware after the anastomat percussion, push pedal not only can not be done the ejector pin action so, connect to clamp and move and to carry out, like this can be when guaranteeing to prevent the mistake percussion and not being repeated to pull the trigger, the doctor can and be dealt with problems in very first time discovery, save operating time.

Description of drawings

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 2, Fig. 3 are two kinds of working state schematic representations of linear anastomat;

Fig. 4 is the structural representation of existing linear anastomat.

Wherein: 1, nail supporting base; 2, nail bin groupware; 21, nail bin; 22, pushing slice of nail; 3, push pedal; 4, nail supporting base clamping plate; 5, assembly clamping plate; 6, safety block; 61, torsion spring.

The specific embodiment

Linear anastomat as shown in Figure 1-Figure 3, comprise body and be arranged on nail supporting base 1, the nail bin groupware 2 on the body and be used to promote the push pedal 3 of nail bin groupware 2, nail supporting base 1 is installed in body foremost by nail supporting base clamping plate 4, push pedal 3 is slidingly arranged on the body, also be provided with the assembly clamping plate 5 that are used for fixing nail bin groupware 2 in the push pedal 3, nail bin groupware 2 and nail supporting base 1 be oppositely arranged and by assembly clamping plate 5 be installed in push pedal 3 front ends, between nail supporting base 1 and push pedal 3.Rotate on the nail supporting base clamping plate 4 and be provided with a safety block 6, this safety block 6 can link together by pin with nail supporting base clamping plate 4, also can link together by modes such as riveted joints, on connectors such as pin, be socketed with torsion spring 61, because be subjected to the active force of torsion spring 61, safety block 6 pops up under naturalness.Assembly clamping plate 5 are avoided safety block 6.Safety block 6 has two operating positions at least, and under first operating position, safety block 6 pops up and blocks push pedal 3, and under second operating position, nail bin groupware 2 is pushed down safety block 6, and this safety block 6 breaks away from push pedal 3.Safety block 6 front ends have a hook portion in this case, and under first operating position, the hook portion of safety block 6 is hooked push pedal 3 front ends.

Operation principle: as shown in Figure 1, when nail bin groupware 2 was unkitted, safety block 6 popped up, its hook portion is hooked the front end of push pedal 3, and when clamping in advance, promoting push pedal 3 can not travel forward, assembly clamping plate 5 and nail bin groupware 2 can not move, so thrust unit also can't move; As shown in Figure 2, when loading onto new nail bin groupware 2, safety block 6 is pressed down and no longer limits push pedal 3, promotes push pedal 3 and travels forward, and assembly clamping plate 5 and nail bin groupware 2 move together to finish and clamp action; As shown in Figure 3, promote percussion lock, the pushing slice of nail 21 that push pedal 3 continuation promote storehouse assembly 2 forward makes the nail molding.Finishing ejector pin action back push pedal 3 moves backward, safety block 6 resets and hooks push pedal 3 again, because after nail bin groupware 2 used, its pushing slice of nail 21 forward can not again safety block 6 being depressed were only reinstalled new nail bin groupware 2 back anastomats and just can be done clamping and ejector pin action.

Existing linear anastomat as shown in Figure 4, its safety block 6 is connected on the assembly clamping plate 5, because assembly clamping plate 5 can be followed push pedal 3 motions, such structure causes not reinstalling after the percussion under the situation of nail bin groupware 2, push pedal 3 still can be done the clamping action, and safety block 6 just anti-thrust plates 3 continue to do the ejector pin action.Though this scheme has error-disable function, can not pinpoint the problems at the very start, on operating-table, time is valuable, if the doctor is put into tissue in the anastomat opening and after clamping, finds that just nail bin is empty by the time, and then the replacing nail bin, then waste a lot of times.This utility model is compared with existing linear anastomat, not only can pinpoint the problems in the very first time, saves operating time, and its nail supporting base clamping plate 4 also do not need bending, and processing is got up more convenient.
