The invention has the beneficial effects as follows：The present invention is by being provided with slide block on the upper surface of operation handle so that medical carePersonnel can directly utilize the operation that stone extraction basket is carried out stretching out or retracting by thumb, greatly when gripping handleImprove the handling of stone extraction basket.
Brief description
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, required in embodiment being described below makeAccompanying drawing be briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention, rather than all implementsExample, those skilled in the art, on the premise of not paying creative work, can also obtain other designs according to these accompanying drawingsScheme and accompanying drawing.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the explosive view of the operation handle of the present invention.
Detailed description of the invention
Carry out clearly below with reference to embodiment and the accompanying drawing technique effect to the design of the present invention, concrete structure and generationIt Chu, is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is thisBright a part of embodiment, rather than whole embodiment, based on embodiments of the invention, those skilled in the art is not payingOther embodiments being obtained on the premise of creative work, belong to the scope of protection of the invention.In addition, literary composition is previously mentionedAll connection/annexations, not singly refer to that component directly connects, and refer to be added deduct by adding according to being embodied as situationCouple auxiliary less, form more excellent draw bail.Each technical characteristic in the invention, in not conflicting conflictUnder the premise of can be with combination of interactions.
With reference to Fig. 1～Fig. 2, the stone extraction basket of a kind of convenient operation, include basket assembly 1, operate handle 2, described netBasket assembly 1 is connected by push rod 3 with operation handle 2, and described operation handle 2 includes housing the 21st, slide block 22, and described housing 21 isHollow is arranged, and the upper surface of described housing 21 is provided with chute, and described slide block 22 is connected with slide, and described slide block 22 includesTop and bottom, described top is located at outside housing 21, and bottom is ensconced in housing 21, and described push rod 3 is connected with the bottom of slide block 22.When needs stretch out basket assembly, only need to use thumb sliding slider so that slipper push push rod advances, and work as and needWhen basket assembly to be regained, also with thumb sliding slider, it is achieved can the one-handed performance of stone extraction basket, improveOperating efficiency.
Being further used as preferred embodiment, the profile of the lower surface of described housing 21 includes asperities.AsperitiesCan be the groove that multiple circular arc is set on lower surface, by arranging asperities, gripping comfort can be increased.
Being further used as preferred embodiment, described basket assembly 1 is arranged on the front of operation handle 2, described operationThe front end of handle 2 is additionally provided with runner 23, and described runner 23 rotates with housing 21 and is connected, and described runner 23 is connected with push rod 3, describedPush rod 3 connects with the bottom axle of slide block 23.By being arranged on the runner of front end, when rotating wheel, driven by rotating wheel push rod turnsDynamic, thus realize the rotation of basket assembly, by utilizing the rotational angle of runner Controling network basket assembly, the operation of convenient operation.
Being further used as preferred embodiment, the front end of described operation handle 2 is additionally provided with infusion connector 4, described transfusionJoint 4 connects with basket assembly 1.In order to coordinate the requirement of operation, add infusion connector in the front end of operation handle, in operationDuring, by infusion connector, liquid can be transported to basket assembly.Of course, in order to ensure in infusion process, liquidMay not flow into and go on operation handle, the front end of described operation handle can be provided with black box, for example seal cock orSealing ring etc..
Above the better embodiment of the present invention is illustrated, but the invention is not limited to described enforcementExample, those of ordinary skill in the art also can make all equivalent modifications or replace on the premise of without prejudice to present invention spiritChanging, these equivalent modification or replacement are all contained in the application claim limited range.
