Abstract

The utility model discloses fascia separating knives on a kind of pectoralis major, including handle of a knife and the cutter head for being set to handle of a knife one end, the blade for detaching fascia between pectoralis major and mammary gland is opened up on the side of cutter head, the Rockwell hardness of blade is 60 80, and the angle between two blade surfaces of blade is 45 60 °.The Rockwell hardness, which is enough to ensure that, detaches the fascia between pectoralis major and mammary gland；And 45 60 ° of the angle between blade surface, angle is excessively sharp less than 45 ° of blades, is easy to damage surrounding tissue, angle is greatly increased more than the too blunt fascia separating difficulty of 60 ° of blades, it is performed the operation using the utility model and not only can easily be detached the fascia between pectoralis major and mammary gland, and in surgical procedure, it is not easy to damage surrounding tissue.

Description

Fascia separating knife on pectoralis major

Technical field

The utility model is related to a kind of breast-enlarging operation instrument, more particularly to fascia separating knife on a kind of pectoralis major.

Background technology

Breast prosthesis can select to be placed between pectoralis major and musculus pectoralis minor between pectoralis major and mammary gland in breast-enlarging operation.Two Kind placement location respectively has quality, is placed on and needs to be divided the fascia between pectoralis major and mammary gland between pectoralis major and mammary gland From, but the fascia separating difficulty between pectoralis major and mammary gland is very big, it is especially desirable to and for the male of chest enlarge, pectoralis major and breast Fascia between gland is more difficult to detach.Scalpel in the prior art, some is excessively sharp, and group around is easy to damage in surgical procedure It knits, some is not sharp enough, and fascia separation is extremely difficult.

Therefore, it is necessary to be improved scalpel in the prior art to solve the above problems.

Utility model content

In view of this, the purpose of this utility model is to provide fascia separating knife on a kind of pectoralis major, can not only facilitate The fascia between pectoralis major and mammary gland is detached, and in surgical procedure, it is not easy to damage surrounding tissue.Specifically It is achieved through the following technical solutions：

Fascia separating knife on the pectoralis major of the utility model, including handle of a knife and the cutter head for being set to handle of a knife one end, cutter head Open up the blade for detaching fascia between pectoralis major and mammary gland on side, the Rockwell hardness of blade is 60-80, two of blade Angle between blade surface is 45-60 °.

Further, the Rockwell hardness of the blade is 70, and the angle between two blade surfaces of the blade is 53 °.

Further, it is provided with the coat of metal outside the blade.

Further, the coat of metal is divided into two layers, is followed successively by zirconium coating and zirconium nitride coating from inside to outside.

Further, 0.3-0.5 ° of micron after the zirconium coating, the zirconium nitride coating are 0.3-0.5 microns.

Further, the other side on the cutter head with respect to blade is provided with sawtooth.

Further, the cutter head and handle of a knife are flat, and cutter head length is 40-50mm, shank length 240- 260mm。

The beneficial effects of the utility model：Fascia separating knife on the pectoralis major of the utility model, the Rockwell hardness of blade are 60-80, the included angle A between two blade surfaces of blade are 45-60 °.The Rockwell hardness is enough to ensure that will be between pectoralis major and mammary gland Fascia detached；And 45-60 ° of the angle between blade surface, angle are excessively sharp less than 45 ° of blades, are easy to damage group around It knits, angle is greatly increased more than the too blunt fascia separating difficulty of 60 ° of blades, and being performed the operation using the utility model can not only facilitate The fascia between pectoralis major and mammary gland is detached, and in surgical procedure, it is not easy to damage surrounding tissue；This practicality is new Other advantageous effects of type will be further described in specific embodiment below.

Description of the drawings

The utility model is further described with reference to the accompanying drawings and examples：

Fig. 2 is the right view of Fig. 1；

Fig. 3 is another pectoralis major fascia separating knife structural schematic diagram corresponding with Fig. 1；

Fig. 4 is the sectional view of the utility model blade and part cutter head；

In figure：1, sawtooth 2, cutter head 3, blade 4, handle of a knife 5, zirconium coating 6, zirconium nitride coating 7, shake hands

Specific implementation mode

As shown, fascia separating knife on pectoralis major in the present embodiment, including handle of a knife 4 and it is set to 4 one end of handle of a knife Cutter head 2, the blade 3 for detaching fascia between pectoralis major and mammary gland is opened up on the side of cutter head 2, and the Rockwell hardness of blade 3 is 60-80, the included angle A between two blade surfaces of blade 3 are 45-60 °, and the other end of handle of a knife forms bending part to be conveniently operated, left The fascia separating knife overbending direction of chest and right chest is opposite.The Rockwell hardness be enough to ensure that by the fascia between pectoralis major and mammary gland into Row separation；And 45-60 ° of the angle between blade surface, angle are excessively sharp less than 45 ° of blades, are easy to damage surrounding tissue, angle The too blunt fascia separating difficulty of more than 60 ° blades greatly increases.

In the present embodiment, the Rockwell hardness of the blade 3 is 70, and the included angle A between two blade surfaces of the blade 3 is 53°.The sharpness of blade is optimal under the parameter area.

In the present embodiment, the coat of metal is provided with outside the blade.The Rockwell that the coat of metal had both been easy to implement blade is set Hardness, and can play a protective role to blade.

In the present embodiment, the coat of metal is divided into two layers, is followed successively by zirconium coating 5 and zirconium nitride coating 6 from inside to outside；Institute 0.3-0.5 ° of micron after zirconium coating is stated, the zirconium nitride coating is 0.3-0.5 microns.Zirconium coating can be viscous with assisted nitridation zirconium coating Knot is on cutter head, and zirconium nitride is hard, smooth, can preferably provide the hardness needed for blade, and wear resistance is good, can also grow Time keeps the retentivity of cutting edge port.

In the present embodiment, the other side on the cutter head 2 with respect to blade 3 is provided with sawtooth 1.Convenient for dividing fascia From, certain sawtooth cannot be excessively sharp, in order to avoid damage surrounding tissue.

In the present embodiment, the cutter head 2 and handle of a knife 4 are flat, and the cutter head and handle of a knife are flat, and cutter head is long Degree is 40-50mm, shank length 240-260mm, and the other end of handle of a knife, which is provided with, shakes hands 7, shakes hands and is provided with tread plate on 7 Line.

Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the right of the utility model.
