Description
Technical field
This utility model relates to a kind of nipper handle, belongs to technical field of medical instruments.
Background technology
In Wicresoft's laparoscopic surgery, needing application specific apparatus forceps class, nipper is to capture the focus foreign body excised in operation, is drawn off external.In prior art, seldom there is nipper clamp not only can reset and strut, but also the nipper handle of locking can be clamped, if there being the nipper handle only clamping locking, or substituting by other pincers classes；Its defect is if clamp will not reset struts, clamps the nipper of locking, and in operation application, clamp struts and must strut with finger, and caliper can shift, being smoothed out of impact operation；Common medical calm class, without card locking device, can not meet preferable operation application effect.
Utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency in the presence of prior art, and provides a kind of reasonable in design, it is possible to effectively location and the nipper handle that resets.
This utility model solves above-mentioned technical problem and be the technical scheme is that a kind of nipper handle, including fixed handle and flexible handle, it is flexibly connected by bolt between fixed handle and flexible handle, it is characterized in that: be cased with back-moving spring on described bolt, the two ends of back-moving spring are fixed with fixed handle and flexible handle respectively；It is provided with tooth plate on described flexible handle, tooth plate is provided with card tooth bar；Being provided with button on described fixed handle, button is connected with fixed handle by pin, and the end of button is provided with latch, and latch snaps in card tooth bar mutual joint match.Holding with a firm grip handle, back-moving spring compresses, and clamp folder closes, and latch snaps in card tooth bar and positions；Now release handle, under the effect of latch and card tooth bar, handle will not unclamp, and clamp retaining clip is closed, and can persistently perform the operation.After having performed the operation, button press, latch disengages with card tooth bar, and under the effect of back-moving spring, handle struts, and clamp is opened.
Having spring eye on fixed handle described in the utility model, button is provided with spring eye, is connected by spring between two spring eyes, the two ends of spring are separately fixed in two spring eyes.Spring makes button have elasticity, and button can be that axle rotates along pin, and button press, latch and card tooth bar disengage；Release button, under the action of the spring, push-button reset.
This utility model compared with prior art, has following positive effect: reasonable in design, can be that clamp effectively positions in operation process by handle, energy Rapid reset after having performed the operation, it is not necessary to moment gripping handles, improves procedure efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment.
Embodiment:
Seeing Fig. 1, the present embodiment includes fixed handle 1 and flexible handle 2, is flexibly connected by bolt 3 between fixed handle 1 and flexible handle 2；Being cased with back-moving spring 4 on described bolt 3, the two ends of back-moving spring 4 are fixed with fixed handle 1 and flexible handle 2 respectively；It is provided with tooth plate 6 on described flexible handle 2, tooth plate 6 is provided with card tooth bar 7；Being provided with button 8 on described fixed handle 1, button 8 is connected with fixed handle 1 by pin 12, and the end of button 8 is provided with latch 10, and latch 10 snaps in card tooth bar 7 mutual joint match.Holding with a firm grip handle, back-moving spring 4 compresses, and clamp folder closes, and latch 10 snaps in card tooth bar 7 and positions；Now release handle, under the effect of latch 10 and card tooth bar 7, handle will not unclamp, and clamp retaining clip is closed, and can persistently perform the operation.After having performed the operation, button press 8, latch 10 disengages with card tooth bar 7, and under the effect of back-moving spring 4, handle struts, and clamp is opened.
In the present embodiment, fixed handle 1 having spring eye 9, button 8 is provided with spring eye 9, connected by spring 13 between two spring eyes 9, the two ends of spring 13 are separately fixed in two spring eyes 9.Spring 13 makes button 8 have elasticity, and button 8 can rotate along pin 12 for axle, and button press 8, latch 10 and card tooth bar 7 disengage；Release button 8, under the effect of spring 13, button 8 resets.
In the present embodiment, make fixed handle 1 and the flexible handle 2 of back-moving spring 4 have elasticity, as long as latch 10 and card tooth bar 7 disengage in the application, fixed handle 1 and flexible handle 2 reset, and nipper clamp struts.
In the present embodiment, under the effect of spring 13, button 8 has elasticity, and latch 10 snaps in card tooth bar 7 all the time, handle of holding with a firm grip, and clamp clamps, it is possible to controls clamp clamping amplitude by the latch 10 position on tooth plate 6, decontrols handle clamp and will not unclamp.Button press 8, latch 10 begins to disengage with tooth plate 6, and clamp resets and struts.
During use, being penetrated by clamp in human body, handle of holding with a firm grip, clamp clamping lesions position, decontrol handle, under the effect of latch 10 and card tooth bar 7, clamp still clamps lesions position, performs the operation, and the focus foreign body of clamping can take out external, reaches optimal surgical effect.After having performed the operation, button press 8, handle resets, and clamp struts.
Furthermore, it is necessary to explanation, the specific embodiment described in this specification, as long as the undeclared concrete shape of its part and size, then this part can be any shape and size adapted with its structure；Meanwhile, the title that part is taken can also be different.All equivalences done according to structure, feature and the principle described in this utility model inventional idea or simple change, be all included in the protection domain of this utility model patent.
