Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0029] The dorsal root ganglion (DRG) is a distended tubercle of the dorsal root of the spinal cord near the medial aspect of each intervertebral foramen. Composed of centripetal sensory fiber cells, it is responsible for receiving all nerve impulses from body receptors, including general somatosensory and visceral sensation, and transmit...

Abstract

The embodiment of the invention discloses a double-drill minimally invasive puncture instrument kit for DRG injection. The double-drill minimally invasive puncture instrument kit for DRG injection comprises a puncture needle, a bone drill, an injector and a guide wire; the puncture needle comprises a puncture sheath tube and a needle core; the puncture needle is used for puncture; the bone drill is used for drilling a spine vertebral plate pierced by the puncture needle; the guide wire is used for replacing the needle core after the puncture needle punctures, and is remained in a puncture channel, wherein the bone drill comprises a hollow trephine and an abrasive drill; the hollow trephine is used for replacing the puncture sheath tube to be arranged outside the guide wire in a sleeving mode to drill the spine vertebral plate, so that the hollow trephine is fixed on the spine vertebral plate; and, the abrasive drill is used for replacing the guide wire to be embedded into the hollow trephine to drill the spine vertebral plate, so that the needle head of the injector can reach the DRG. In the embodiment of the invention, through the cooperation of the bone drill and the puncture needle, minimally invasive puncture of DRG injection is realized; and the safety of the drilling process is improved through the double drills.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a double-drill minimally invasive puncture device set for DRG injection. Background technique [0002] Pain is a persistent disease that plagues human beings. It was listed as the fifth vital sign by the World Health Organization in 2000, and 73% of people will experience severe pain in their lifetime. The most common types of neuropathic pain are discogenic pain and pain after nerve injury. Clinically, there are as many as 159 etiologies for low back pain alone. With the advent of aging and the increasing number of vehicles, neuropathic pain caused by spinal degeneration and injury is increasing. Due to the complexity of the etiology, the difficulty in defining the diagnostic criteria, the inaccurate treatment methods, and the serious phenomenon of misdiagnosis and mistreatment, it is difficult to obtain Early, effective, and standardized diagnosis and treatme...
