Problems solved by technology

The problem brought about by this is that the large-diameter needle tube will cause greater trauma to the skin, and the patient's pain will be greater. Many patients cannot receive treatment because they are afraid of the thick needle tube.
In addition, clinically, for the implantation of large-volume materials, a certain amount of local anesthetic must be injected in advance to operate.
Another problem is that during the process of gradual absorption, the diameter of the material gradually shrinks, the amount of stimulation gradually decreases, and the therapeutic effect gradually disappears. It is necessary to re-inject the thread body to obtain stimulation.

Effect test

Embodiment 1

[0027] 2 grams of polycaprolactone, 2 grams of xanthan gum powder, and 8 grams of tetrahydrofuran were stirred at room temperature at 40°C to obtain a mixture of polycaprolactone-tetrahydrofuran solution and xanthan gum, and then heated at 80°C for 30 minutes to make The tetrahydrofuran was evaporated to give a polycaprolactone-xanthan gum mixture. After 50 mg of polycaprolactone-xanthan gum mixture was placed in saline at 37°C for 45 minutes, the weight increased to 167 mg due to water absorption.

Embodiment 2

[0029] Extrude the mixture of polycaprolactone and xanthan gum obtained in Example 1 through capillary holes at 80-120° C. to obtain polycaprolactone-xanthan gum linear acupuncture implant material. Ethanol is evaporated in a vacuum state, cut into 0.5cm-2cm line segments after cutting, sterilized and packaged for later use.

Embodiment 3

[0031] The polycaprolactone-tetrahydrofuran solution obtained in Example 1 and the xanthan gum mixture were injected into absolute ethanol through the capillary pores, and the tetrahydrofuran was removed to obtain the polycaprolactone-xanthan gum linear acupuncture implant material. Evaporate the ethanol in a vacuum at 50°C, cut it into 0.5cm-2cm line segments, sterilize and pack them for later use.

Abstract

The invention relates to an acupuncture implantation material, and particularly relates to the acupuncture implantation material with the combination of hydrophilicity polyose and degradable synthesizing high polymer. Specifically, the degradable high polymer and the hydrophilicity polyose are mixed to be molded, the degradable high polymer plays a role of binding the hydrophilicity polyose, and the hydrophilicity polyose plays the role of the imbibition. The acupuncture implantation material provided by the invention has the imbibition characteristic, implantation needles with same diameters are applied into acupoint implantation, the acupoint quantity of stimulation action is obtained, the anguish and fear of patients are greatly reduced in acupoint implantation, and the acupuncture implantation material is beneficial to clinical treatment.

Description

technical field [0001] The invention relates to an acupuncture implant material, in particular to an acupuncture implant material combined with a hydrophilic polysaccharide and a degradable synthetic high polymer, specifically, a degradable high polymer and a hydrophilic polysaccharide are mixed and formed , by regulating its water-absorbing swelling property, an embedded acupuncture and moxibustion implant material that can be implanted in acupoints with small wounds but obtains a large amount of acupoint stimulation can be prepared. Background technique [0002] The indications of acupuncture and moxibustion are very extensive, including internal, external, gynecological, and pediatric diseases. According to statistics, there are more than 300 kinds, of which 200 have remarkable curative effects, especially neurology and other diseases. For some refractory diseases, such as stroke, cerebral palsy in children, nerve damage caused by various reasons, spinal lesions, rheumati...
