Problems solved by technology

[0003] The operation needs to be punctured under local anesthesia with a guide needle while the patient is awake. The insertion end of the existing intervertebral foramina guide needle is usually a needle-like structure, which is likely to cause minor damage to the patient's tissue during the operation

Embodiment

[0020] like figure 1 As shown, a transforaminal mirror guide pin of the present invention includes a guide pin body 1, and one end of the guide pin body 1 is an insertion end 11, which is used to insert the intervertebral foramen from the side or rear of the patient's body to perform surgery . The end face of the insertion end 11 is arc-shaped, and a diameter-reducing portion 12 is provided on the guide needle body 1 close to the insertion end 11 . The end surface of the insertion end 11 of the transforaminal mirror guide wire is set in an arc shape, and a diameter-reducing portion 12 is provided near the insertion end 11, so that the insertion end 11 forms a drop-shaped structure, compared with the existing needle-shaped guide wire Therefore, the guide needle with the drop-shaped needle structure of the present invention can perform puncture more safely, and can avoid damage to patient tissues during the operation.

[0021] In this embodiment, the material of the guide need...

Abstract

The invention discloses an intervertebral foramen endoscope guide needle. The intervertebral foramen endoscope guide needle comprises a guide needle body (1), wherein one end of the guide needle body (1) is an insertion end (11), and the end face of the insertion end (11) is in an arc shape; and a diameter reducing part (12) is arranged at the position, close to the insertion end (11), of the guide needle body (1), so that the insertion end (11) is of a water-drop-shaped structure. Compared with an existing needle-shaped guide needle, the intervertebral foramen endoscope needle can implement puncture more safely, and damage to tissue of a patient in the operation implementation process can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to an intervertebral foramen mirror guide pin. Background technique [0002] The purpose of the transforaminal minimally invasive spinal technique is to establish a working channel from the side or rear of the patient's body to enter the intervertebral foramen, and to completely remove the protruding or prolapsed spinal cord outside the safe triangle of the intervertebral foramen and the fibrous annulus of the intervertebral disc. Nuclei and hyperplastic bone to relieve the pressure on the nerve root, relieve the obstruction of lateral recess circulation caused by disc herniation, nerve root edema and aseptic inflammation again, resulting in recurrence of clinical symptoms. The operation method is a spinal minimally invasive surgery system composed of a specially designed intervertebral foramenoscope, corresponding supporting spinal minimally invasive surgica...
