Abstract
A kind of endoscopic biopsy anti-sheet pincers, be by: mobile jib, handle, chute, slide block, location-plate, spring, pulling rope, pliers are formed; Take out of in extracorporeal procedures in pliers grip tissue or foreign body, elasticity stable, clamping dynamics can be kept invariable, avoid tissue or foreign body to be caught broken, bring unnecessary trouble to operating process, simplify operation easier, increase work efficiency, ensure that the safety of operating process.
Description
Technical field
This utility model relates to medical instruments field, especially a kind of endoscopic biopsy anti-sheet pincers.
Background technology
At present, when using taking foreign body or specimen under bronchoscope clinically, dynamics size depends on that operator oneself grasps.When operator grasps gripping by finger strength, form external force pressurization, dynamics is excessive to be easily caught broken, and dynamics is too small not easily presss from both sides out.In gripping process, operator easily causes dynamics to change, and cannot dynamics be kept constant always.
In view of the foregoing, existing endoscope biopsyforceps needs to improve.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of endoscopic biopsy anti-sheet is provided to clamp, take out of in extracorporeal procedures in pliers grip tissue or foreign body, elasticity stable, can keep clamping dynamics invariable, avoids tissue or foreign body to be caught broken, unnecessary trouble is brought to operating process, simplify operation easier, increase work efficiency, ensure that the safety of operating process.
This utility model to achieve these goals, adopts following technical scheme: a kind of endoscopic biopsy anti-sheet pincers, be by: mobile jib, handle, chute, slide block, location-plate, spring, pulling rope, pliers are formed; Arrange handle above mobile jib, below is set to taper, arranges chute in the middle part of mobile jib, and on mobile jib, corresponding chute arranges slide block; Middle part in slide block arranges location-plate, and the lateral symmetry of location-plate arranges semicircular cavities, and described location-plate is corresponding with chute to be arranged, and two semicircular cavities are corresponding with the mobile jib of chute both sides to be arranged; Arrange pulling rope in preformed hole below mobile jib, one end of pulling rope is corresponding with below location-plate to be arranged, and the other end of pulling rope arranges pliers, correspondingly with between chute inner top above location-plate arranges spring.
The beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, easy to operate, processing and manufacturing cost is low, mounting spring in the chute of mobile jib, one end of spring is connected with the location-plate of slide block, the other end is connected with mobile jib, under naturalness, pliers is closure state, during operation, forefinger and middle finger grip slide, thumb is through the hands handle above mobile jib, slide block is moved up along chute, make spring compacted thus produce elastic force, slide block drives one end of pulling rope upwards, with tissue or abnormal contact after making the pliers of the pulling rope other end open, forefinger and middle finger slowly loosen slide block, the elastic force of spring makes slide block move down along chute, after making pliers close grip tissue or foreign body gradually, lift mobile jib, pliers grip tissue or foreign body are taken out of external, take out of in extracorporeal procedures in pliers grip tissue or foreign body, due to elasticity stable, clamping dynamics can be kept invariable, tissue or foreign body is avoided to be caught broken, unnecessary trouble is brought to operating process, simplify operation easier, increase work efficiency, ensure that the safety of operating process, result of use is desirable, be applicable to promoting the use of.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is, general assembly structural representation;
Fig. 2 is, structural representation is overlooked/looked up to slide block;
In Fig. 1,2: mobile jib 1, handle 2, chute 3, slide block 4, location-plate 4-2, spring 5, pulling rope 6, pliers 7.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail:
As shown in the figure, arrange handle 2 above mobile jib 1, below is set to taper, arranges chute 3 in the middle part of mobile jib 1, and on mobile jib 1, corresponding chute 3 arranges slide block 4; Middle part in slide block 4 arranges location-plate 4-2, and the lateral symmetry of location-plate 4-2 arranges semicircular cavities, and described location-plate 4-2 is corresponding with chute 3 to be arranged, and two semicircular cavities are corresponding with the mobile jib 1 of chute 3 both sides to be arranged; Arrange pulling rope 6 in preformed hole below mobile jib 1, one end of pulling rope 6 is corresponding with below location-plate 4-2 to be arranged, and the other end of pulling rope 6 arranges pliers 7, correspondingly with between chute 3 inner top above location-plate 4-2 arranges spring 5.
