Abstract
The utility model discloses a vitrectomy handle, which is characterized in that the surface of a working head (2) of the vitrectomy handle (1) is coated with a diamond like carbon (DLC) coating (3) which is a cathodic sputtering DLC film. The vitrectomy handle has advantages of high strength and hardness, abrasion and corrosion resistance and dazzling resistance, smooth surface, reduced friction, good sharpness, convenient processing and mass production and manufacturing.
Description
Technical field
This utility model relates to a kind of medical ophthalmological instruments, especially relates to a kind of glass and cuts handle.
Background technology
Modern age ophthalmologic operation development, vitreous excision operation is more and more widely used.Will go deep into a transluminal operation because glass is cut the work head of handle, its work head is all more tiny, meticulous, and very easily wearing and tearing, and the edge of a knife must be sharp, guarantees operation safety.So people are making great efforts intensity, hardness, the increase wearability of raising work head always, improve the sharpness of working head.
When cutting the handle use owing to glass again, chieftain's inner core of operate portions slides in pipe.In order to use flexibly, manage to reduce as much as possible friction.
In addition, present common glass is cut handle and is also had devices work portion surface brightness height, and dazzle is arranged, and the doctor increases the shortcomings such as fatigue strength of eyes in operation easily.
The utility model content
The purpose of this utility model is: provide a kind of glass to cut handle, its intensity height, wear-resistant corrosion-resistant, anti-dazzle, sharpness are excellent.
The technical solution of the utility model is: a kind of glass is cut handle, and the working head working portion surface plating that described glass is cut handle is provided with diamond-like coating.
Below be further explanation to technique scheme:
The working head working portion inner and outer pipes surface plating that described glass is cut handle is provided with diamond-like coating.
Described diamond-like coating is a cathodic sputtering diamond like carbon rete.
Described working head diameter is ￠ 0.4mm～￠ 1.4mm.
The utility model has the advantages that:
1. glass of the present utility model is cut handle, and have high strength, wear-resistant, corrosion-resistant, anti-dazzle, smooth surface, reduce friction, sharpness is excellent, and easy to process, can produce manufacturing in enormous quantities.
2. glass of the present utility model is cut handle, and the diamond like carbon of its working head (DLC) coating is a black, effectively prevents the working head dazzle, makes the ophthalmologist in use feel more comfortable, and is not tired.
3. glass of the present utility model is cut handle, can effectively reduce the inner and outer pipes resistance of motion, operates more comfortable.
4. glass of the present utility model is cut handle, and inner and outer pipes work edge of a knife sharpness improves, and has increased the safety of operation.
5. glass of the present utility model is cut handle, and the Corrosion Protection height is durable in use.
6. glass of the present utility model is cut handle, has operate portions body more attractive in appearance.
7. glass of the present utility model is cut handle, and the diamond like carbon of its working head (DLC) film adopts the cathodic sputtering mode to be provided with, and the adhesion with rete and base material is strong, rete densification, advantage such as even.
8. glass of the present utility model is cut handle, and the rete of its working head has good blood compatibility, that is to say that biological capacitive is good.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 glass is cut the hands handle; 2 working heads; 3 diamond-like coatings.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of glass is cut handle, and the working head 2 working portions surface plating that this glass is cut handle is provided with diamond-like coating 3.This diamond like carbon (DLC) coating adopts cathodic sputtering technology to carry out plated film in certain temperature.Its working head 2 working head diameter D are within ￠ 0.4mm～￠ 1.4mm scope.
Should be pointed out that for this utility model also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned embodiment through proving absolutely.The foregoing description is as just explanation of the present utility model, rather than restriction.In a word, protection domain of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
