Abstract
The utility model discloses a kind of binding clip assembly of biopsy forceps, comprise binding clip frame, binding clip frame is hinged with upper grip head and lower pliers head binding clip top of the trellis is provided with thimble, upper grip head shear surface and lower pliers head shear surface are all arranged in sequence with and gnaw tooth, gnaw tooth tapered, gnawing tooth addendum angle α is 15 ° ~ 75 °, gnaws tooth angle between teeth β equal with addendum angle α angle.This utility model, by arranging thimble, facilitates doctor to determine pathological tissues position fast; Upper and lower binding clip shear surface designs and in a row gnaws tooth, when harder pathological tissues, sample faster.
Description
Technical field
This utility model relates to a kind of binding clip assembly of biopsy forceps, belongs to medical instruments field.
Background technology
At present, to be taken a sample to check certain diseased region tissue in human body by endoscope, having Micro trauma, the painful advantage such as little, is a kind of conventional also more welcome diagnostic method.And biopsy forceps is one of requisite medical apparatus in splanchnoscopy, often along with endoscope channel stretches in body, gripping pathological tissues, to be used as pathological analysis.Therefore, the service property (quality) of biopsy forceps will directly affect the quality of Checking on effect.
Although the biopsy forceps of all styles of is thoroughly now, still face 2 large predicaments in use: one is the accurate location be difficult to when sampling pathological tissues; Two is for the harder tumor tissues etc. in some top layers, and sampling difficulty, compares and waste time and energy, add the misery of patient.
Utility model content
The purpose of this utility model is to provide a kind of binding clip assembly of biopsy forceps, to overcome currently available technology above shortcomings.
For achieving the above object, the technical solution of the utility model is: a kind of binding clip assembly of biopsy forceps, comprise binding clip frame, binding clip frame is hinged with upper grip head and lower pliers head binding clip top of the trellis is provided with thimble, upper grip head shear surface and lower pliers head shear surface are all arranged in sequence with and gnaw tooth, gnaw tooth tapered, gnawing tooth addendum angle α is 15 ° ~ 75 °, gnaws tooth angle between teeth β equal with addendum angle α angle.
The beneficial effects of the utility model are: by arranging thimble, facilitate doctor to determine pathological tissues position fast; Upper and lower binding clip shear surface designs and in a row gnaws tooth, when harder pathological tissues, sample faster.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: binding clip frame 1, upper grip head 21, lower pliers head 22, shear surface 211,221, thimble 3, gnaw tooth 4, addendum angle α, angle between teeth β.
Detailed description of the invention
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, this utility model is described further.
Embodiment:
As shown in Figure 1, a kind of binding clip assembly of biopsy forceps, comprises binding clip frame 1, binding clip frame 1 is hinged with upper grip head 21 and lower pliers head 22, binding clip frame 1 top is provided with thimble 3, and this thimble 3 is an overall structure with binding clip frame 1, is formed by lathe car system, upper grip head 21 shear surface 211 and lower pliers head 22 shear surface 221 are all arranged in sequence with and gnaw tooth 4, gnaw tooth 4 tapered, gnawing tooth 4 addendum angle α is 15 ° ~ 75 °, gnaws tooth 4 angle between teeth β equal with addendum angle α angle, make to gnaw tooth 4 sharper, sample faster.
This utility model in use, is first touched by thimble 3 and is determined diseased region tissue, and then engaged by the tooth 4 of gnawing on upper grip head 21 and lower pliers head 22, fast sampling from diseased region tissue.
