Abstract
The utility model provides a living body sampling forceps, including the binding clip subassembly, handle assembly, spring outer tube and cable, the binding clip subassembly is by the binding clip, the pincers headstock, coupling mechanism constitutes, handle assembly is by the sliding ring, the core bar, the bracelet is constituteed, it is intraductal to be located the spring outer tube to butt joint pipe and cable, coupling mechanism and butt joint pipe one end in the binding clip subassembly are connected, the butt joint pipe other end is connected with cable one end, the cable other end is connected with the sliding ring, spring outer tube one end is connected with the binding clip frame, the spring outer tube other end is connected with the core bar, the cable adopts stainless steel material to make, and the surface of cable has glossy. The utility model discloses because there is the glossy plastic coating of one deck on the cable surface, can effectively reduce the frictional resistance between the binding clip in-process cable of opening and shutting and the outer pipe inner wall of spring for the binding clip opens and shuts in a flexible way, facilitates for doctor's operation, shortens the sample time, thereby alleviates patient's misery, compares simultaneously and adopts teflon sleeve's structure greatly reduced manufacturing cost.
Description
Technical field
This utility model relates to a kind of biopsy forceps, belongs to medical instruments field, is used for the living body sampling under the endoscope.
Background technology
At present, splanchnoscopy has been widely used in clinical as a kind of aided diagnosis method.Sample pickup tongs gets into gripping diseased region tissue in the patient body through the speculum forceps road, again the tissue that presss from both sides out is carried out pathological analysis to make a definite diagnosis disease.Endoscope's living tissue sampling is little because of its wound, the convenient splanchnoscopy means that become routine of inspection.
The most sample pickup tongs that use now mainly are made up of binding clip assembly, drag-line, spring outer tube and handle.The binding clip assembly exists coupling type (like Fig. 1) and four link type bindiny mechanisms such as (like Fig. 2).Drag-line is made by the rustless steel steel wire rope; For reducing frictional resistance between steel wire rope and spring outer tube wall, adopt the method for lining Teflon sleeve pipe between drag-line and spring outer tube, but existing Teflon pipe production technology is difficult to guarantee its inside/outside diameter size precision; Make sample pickup tongs in clinical use, be prone to the inflexible phenomenon of binding clip folding; Strengthen doctor's operation easier, increased sample time, thereby increased patient's misery.And use that the Teflon sleeve pipe exists that price is higher, complex manufacturing, shortcoming that work efficiency is lower.
Summary of the invention
The purpose of this utility model provides that a kind of cost is low, binding clip folding biopsy forceps flexibly.
The technical scheme that realizes above-mentioned purpose is: a kind of biopsy forceps, comprise binding clip assembly, Handleset, spring outer tube and drag-line, and the binding clip assembly is made up of binding clip, binding clip frame, bindiny mechanism; Handleset is made up of slip ring, core bar, bracelet, and butt tube and drag-line are positioned at the spring outer tube, and the bindiny mechanism in the binding clip assembly is connected with butt tube one end; The butt tube other end is connected with drag-line one end; The drag-line other end is connected with slip ring, and spring outer tube one end is connected with the binding clip frame, and the spring outer tube other end is connected with core bar; Drag-line adopts stainless steel material to process, and the surface of drag-line has slick plastic coating.
After adopting technique scheme; Because there is the slick plastic coating of one deck in the drag-line surface, can effectively reduce the frictional resistance between drag-line and spring outer tube wall in the folding binding clip process, make that the binding clip folding is flexible; Facilitate to doctor's operation; Shorten sample time, thereby alleviate patient's misery, compare simultaneously and adopt the structure of Teflon sleeve pipe to greatly reduce production cost.
Description of drawings
Fig. 1 is the binding clip modular construction sketch map of coupling type bindiny mechanism;
Fig. 2 is the binding clip modular construction sketch map of four link type bindiny mechanism;
Fig. 3 is the assembly structure sketch map of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is done further detailed explanation.
Shown in Fig. 1 ~ 3, a kind of biopsy forceps comprises binding clip assembly, Handleset, spring outer tube 9 and drag-line 8; The binding clip assembly is made up of binding clip 1, binding clip frame 2, bindiny mechanism 3, and Handleset is made up of slip ring 4, core bar 5, bracelet 6, and butt tube 7 is positioned at spring outer tube 9 with drag-line 8; Bindiny mechanism 3 in the binding clip assembly is connected with butt tube 7 one ends, and butt tube 7 other ends are connected with drag-line 8 one ends, and drag-line 8 other ends are connected with slip ring 4; Spring outer tube 9 one ends are connected with binding clip frame 2; Spring outer tube 9 other ends are connected with core bar 5, and drag-line 8 adopts stainless steel material to process, and the surface of drag-line 8 has slick plastic coating.
The operation principle of this utility model is following:
Link to each other through bindiny mechanism 3 in plastic drag-line 8 one ends and the binding clip assembly, the other end links to each other with slip ring 4, and drag-line 8 is in spring outer tube 9, and an end of spring outer tube 9 links to each other with binding clip frame 2, and the other end links to each other with core bar 5.Push away, draw slip ring 4 to drive drag-line 8, drag-line 8 drives bindiny mechanism's 3 actions, and two symmetrical binding clips 1 that bindiny mechanism 3 drives on the binding clip assembly are realized folding, thereby play the effect of gripping tissue.There is the slick plastic coating of one deck in drag-line 8 surfaces, can effectively reduce the frictional resistance between plastic drag-line 8 and spring outer tube 9 inwalls in the folding binding clip process.
