Chitosan is a product of n-deacetylated chitosan. Chitin, chitosan and cellulose have similar chemical structure. Cellulose is hydroxyl group at C2 position, chitin and chitosan are replaced by an acetyl group and an amino group respectively at C2 position. Chitin and chitosan have many unique properties such as biodegradability, cell affinity and biological effect, especially chitosan containing free amino group, which is the only basic polysaccharide in natural polysaccharides.

Notes:
1.Sterilize temperature ≤ 135 °C (Improved type ≤ 155 °C ),if the     temperature is over 135 ° C ,the motor will be damaged. 2.Normal bone drill can only hold drill bits less than 6mm,acetabulum     reaming drill with big torque,rpm is around 300,canulate drill is used     with nail or K wire ,rpm is around 600. 3.The battery need to be get out of the pwer tool after surgery. Otherwise     the small automatic discharge of the electric will make the life of the     battery short. 4.The battery cannot be sterilized ,it is not autoclavable. 5.The cranial bur must be washed right after the surgery by purger in     order to aviod the blood stick in the bur,then we should make it dry. 6.The battery space in the handpiece of the tool should not have any     water,after sterilization. 7.The cranial bur blade is made of medical stainless steel,in order to     avoid broken,so it is flexible and not very hard,it is easy to be attrite,     we suggest each blade only use for 1 surgery. 
                                         About us:
     Established in 1993 and headquartered in Shanghai, Bojin, as an advanced orthopedic equipmentÂ
manufacturer and solutions provider, Bojin focuses on the development and marketing of orthopedic-
purpose motor products, X-ray imagescopes, treatment apparatus, and supporting surgical tools/parts.
It has more than one hundred types of orthopedic products under 8 series, which have received QCÂ
certification of 3C, ISO9001, ISO13485, CE of the EU, and FDA Registry 3008787426. Its mission
is to satisfy the needs of patients and medical care with innovative high-tech products and thereforeÂ
become a promoter of people's orthopedic health.It has built a healthy sales and services networkÂ
thanks to its 200 dedicated employees in the marketing companies or teams in more than 4countriesÂ
and regions across North America, Europe and Asia. Its products are used in more than 60 countriesÂ
and, in particular, in more than 20000 Chinese.medical institutions 70% of which are 3A-rated hospitals.
The amino groups in the chitosan molecular structure are more reactive than the acetylamino groups in the chitin molecule, which makes the polysaccharide have excellent biological functions and can carry out chemical modification reaction. Therefore, chitosan is considered as a functional biomaterial with greater application potential than cellulose.
Chitosan is the product of natural polysaccharide chitin removing part of the acetyl group, with biodegradability, biocompatibility, non-toxicity, antibacterial, anti-cancer, lipid-lowering, immune enhancement and other physiological functions. Widely used in food additives, textile, agriculture, environmental protection, beauty care, cosmetics, antibacterial agent, medical fiber, medical dressings, artificial tissue materials, drug slow release materials, gene transduction carrier, biomedical fields, medical absorbable materials, tissue engineering carrier materials, medical and drug development, and many other fields and other daily-use chemical industry.
