Absorptive bone hemostatic agent

Abstract

The invention discloses an absorbable bone hemostatic agent used in surgery or orthopedic operations, which mainly includes 20-95 parts of chitosan or modified chitosan, konjac glucomannan or carboxymethylated modified 5-80 parts of konjac glucomannan, water is 50%-500% of the total weight of the solid. It is prepared by mixing solid powder or aqueous solution with another solid powder or aqueous solution. The hemostatic agent of the invention is easy to operate, has good compatibility, has no stimulating inflammation reaction, and can induce bone growth.

Description

technical field

[0001] The invention relates to a bone hemostatic agent used in surgical or orthopedic operations, which is mainly made of absorbable biological materials. Background technique

[0002] Most of the bone hemostatic agents used in neurosurgery or orthopedic surgery use bone wax to achieve the purpose of hemostasis on bone wounds through the mechanical force filling effect of the bone wax's unique hardness, toughness and viscosity at a certain temperature. Bone wax is mainly composed of beeswax, vegetable oil, etc. It is dark yellow and is generally produced for self-use. When in use, take an appropriate amount of bone wax with your fingers, knead it into a certain shape, and press it on the bleeding surface of the bone to achieve hemostasis. However, this type of product can sometimes fail to achieve the hemostatic effect of the bone during use, and cannot stop the momentum of the bone oozing blood. After mixing with the blood, it becomes loose and falls off l...
