Description
Technical field
The utility model belongs to the field of medical instrument technology, more particularly to a kind of biopsy forceps head with nano coating.
Background technology
With the continuous development of medical technology, the method for minimally invasive detection and treatment disease is becoming increasingly popular.But minimally invasive device
Tool such as biopsy forceps, hemostatic clamp etc. will enter human body by oral cavity, directly and human contact, therefore to itself and human body contact portion's instrument
Various aspects of performance requirement.
Biopsy forceps is the indispensable tool of endoscopy case sample, binding clip have can cut into tissue damage mucous membrane with
Sample sharp sword is obtained, binding clip can retain the inner cavity of histotomy when being closed.Biopsy forceps head is generally made of stainless steel, stainless
Steel material contacts hydrochloric acid in gastric juice, liquid etc. in use, is easy to be corroded；Biopsy forceps head generally uses powder metallurgy at this stage
It is made, powdered metal parts are sintered by powder particle, even if after subsequently carrying out mechanical polishing processing, binding clip surface can still deposit
The tiny aperture or out-of-flatness the problem of, and inside of human body tissue is weak, should avoid burr out-of-flatness as possible.
Utility model content
The purpose of this utility model is to provide a kind of surface roughness, precision, cutting edge sharpness, corrosion resistance, tables
The good biopsy forceps head with nano coating of the performances such as face antibiotic property solves technical problem present in background technology.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of biopsy forceps head with nano coating, including pincers cup, connection sheet, pin, cup holder and push-pull rod, the pincers
Cup includes No.1 pincers cup and No. two pincers cups, and the cutting edge inclined-plane of No.1 pincers cup clamps the inner wall of cup, the cutting edge of No. two pincers cups towards No.1
The inner wall of the outer wall that inclined-plane clamps cup towards No. two, the outer walls and No.1 pincers cup of No. two pincers cups coordinates for transition, No.1 pincers cup and two
Number surfaces Qian Bei are equipped with nano coating.Have benefited from enhancing of the nano coating to pincers cup cutting edge sharpness and wearability, No.1 clamps cup
With No. two pincers cups by the way of cutting cutting tissue, traditional binding clip is compared to butt formula, cuttability is more preferable.
Preferably, the connection sheet, pin, cup holder and push-pull rod surface are equipped with nano coating.Nano coating changes
Be apt to biopsy forceps head surface through tradition polish after there are still tiny aperture or out-of-flatnesses the problem of, to make binding clip rough surface
Degree reduces, precision improves, cutting edge is sharper, corrosion resistance and antibacterial surface enhance.
Preferably, the nano coating is nano thermal spraying coating, nano-plating coating, Nano sol-gel painting
One kind in layer, nano paint coating.
Preferably, the nano coating is to contain Al2O3Nano particle, ZnO nano particle or TiO2Nano particle
Coating.Al2O3Nano coating can make binding clip abrasion-resistance improve 3 times, ZnO, TiO2Nano coating can improve the antibiotic property of binding clip
Energy.
The utility model has the beneficial effects that：
The utility model by nano coating improve biopsy forceps head surface through tradition polish after there are still tiny apertures
Or the problem of out-of-flatness, so that binding clip surface roughness is reduced, precision improves, cutting edge is sharper, corrosion resistance and antibacterial surface
Property enhancing；It is short, efficient the time required to nano processing technology compared with tradition machinery polishes.

Specific implementation mode
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made further specifically
It is bright.It should be appreciated that the implementation of the utility model is not limited to the following examples, any form that the utility model is done
On accommodation and/or change fall within scope of protection of the utility model.
Embodiment：
A kind of biopsy forceps head with nano coating as depicted in figs. 1 and 2, including pincers cup 1, connection sheet 2, pin 3, cup
Seat 4 and push-pull rod 5, pincers cup include No.1 pincers cup 11 and No. two pincers cups 12, and the cutting edge inclined-plane that No.1 clamps cup clamps cup towards No.1
Inner wall, the outer wall of No. two pincers cups of cutting edge inclined-plane direction of No. two pincers cups, the inner wall of No. two outer walls for clamping cup and No.1 pincers cup were
Cooperation is crossed, No.1 clamps cup and No. two surfaces Qian Bei are equipped with nano coating 101, and connection sheet, pin, cup holder and push-pull rod surface are all provided with
There is nano coating.The nano coating is nano-plating coating, and coating adds Al2O3Nano particle, increase substantially it
Hardness and abrasion-resistance.
It significantly shorter than mechanically polishes, is normally only needed in more than ten seconds to two minutes the time required to Nano surface treatment technology
Workpiece surface processing is completed, the production efficiency of biopsy forceps head is improved.Nano coating treated binding clip has better property
Can, and small, coating uniform is influenced on binding clip size；Binding clip surface will produce one layer of passivating film during nanometered disposal, that is, receive
Rice coating, the addition of coat side enhance the corrosion resistance and inoxidizability of binding clip.After nanometered disposal, the characteristic of binding clip is main
It shows：The low precision of binding clip surface roughness is high, cutting edge is sharper, corrosion resistance and antibacterial surface enhancing etc..
Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any
Formal limitation, on the premise of not exceeding the technical scheme recorded in the claims also other variations and modifications.
