Abstract
The utility model discloses a nanometer ta-C coating scalpel which comprises a handle. The handle is a regular eight-edge prism body. Corner angles of the regular eight-edge prism body are rounded. A blade is fixedly connected with the front end of the handle and is of a falcate shape. The blade comprises a stainless steel base body and a nanometer ta-C thin film layer covering the stainless steel base body. Compared with the prior art, the nanometer ta-C coating scalpel can reduce the amount of bleeding in the process of an operation, increase the sharpness of operation cutters, improve abrasive resistance of the cutters, and therefore reduce the pain of patients.
Description
Technical field
This utility model relates to medical surgical knife, is specifically related to a kind of nanometer ta-C coating scalpel for Minimally Invasive Surgery.
Background technology
The operation that Minimally Invasive Surgery refers to utilize the modern medical equipment such as peritoneoscope, thoracoscope and relevant device to carry out, in recent ten years, Minimally Invasive Surgery is little because of its wound, pain light, it is fast to recover, hospital stays five large advantages short, that go out insufficiency of blood are widely used.Particularly, Minimally Invasive Surgery is to open the approximately little otch of 1cm at patient's affected part, implant the micro catheter with little operation Camcording system along this otch, by Camcording system the diseased region tissue is amplified tens times and also clearly project on the TV monitor, the recycling Micro operating knife is with excision of the lesion.Minimally Invasive Surgery is reducing Principle of Pain, is reducing and positive meaning is arranged aspect hemorrhage, but because the scalpel that present Minimally Invasive Surgery is used is to adopt the size that reduces operation tool and the intensity that improves operation tool to reduce to bleed, ease the pain, still can not reach the amount of bleeding in the obvious minimizing operation process, and alleviate the purpose of patient's misery.
The utility model content
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of nanometer ta-C coating scalpel is provided, and uses that amount of bleeding is few in the process that this scalpel performs the operation, the cutter wearability is good, cuts and organizes efficient high.。
For achieving the above object, this utility model adopts following technical scheme:
A kind of nanometer ta-C coating scalpel, it comprises handle, described handle is positive eight prisms, the corner angle of positive eight prisms are established rounding, the front end of handle is fixedly connected with blade, described blade is sickleshaped, and described blade comprises stainless steel base and the nanoscale ta-C thin layer that covers on the stainless steel base.
Two arc-shaped side edges of described blade are blade.
The angle that described blade and handle consist of is 15 °.
Compared with prior art, the beneficial effects of the utility model are:
1, handle of the present utility model is six prisms, and corner angle establish rounding, makes things convenient for user rotary operation cutter and scalpel can not come off easily.
2, blade of the present utility model is sickleshaped, and covered nanoscale ta-C thin layer at the high stainless steel base of intensity, good with the intermiscibility of tissue, and hardness is high, anti-wear performance is good, compactness is high, can reduce the amount of bleeding in the operation process, alleviate the damage of cell, thereby alleviate patient's misery; Moreover sickle-shaped blade sharpness is good and can make things convenient for the doctor to cut the position that varies in size, and has increased the function of blade, and two arc-shaped side edges of blade are blade, can be to inscribe or to circumscribed when operation, and convenient and swift, increase work efficiency, alleviate patient's misery.
3, the angle of blade and handle formation is 15 °, can be adapted at processing muscle cell in less, the significantly not good situation in the visual field.
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment
Please refer to Fig. 1, nanometer ta-C coating scalpel of the present utility model comprises handle 1 and blade 2.Described handle 1 is positive eight prisms, and the corner angle of positive eight prisms are established rounding 1a.The front end of handle 1 is fixedly connected with blade 2, and described blade 2 is sickleshaped, and described blade 2 comprises stainless steel base 2a and the nanoscale ta-C thin layer 2b that covers on the stainless steel base 2a, as shown in Figure 2.
As this utility model preferred embodiment, in order to have increased the function of blade 2, increase work efficiency, two arc-shaped side edges of described blade 2 are blade.
As the another kind of preferred implementation of this utility model, in the situation that the visual field is less, the significantly not good muscle cell of accurately processing, described blade 2 is 15 ° with the angle that handle 1 consists of.
Above-mentioned embodiment only is preferred implementation of the present utility model; can not limit with this scope of this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to this utility model scope required for protection.
