Abstract

The utility model discloses a spinal puncture tunnel guide external member, comprising a puncture needle tube, a puncture needle core and a puncture tunnel tube, wherein, the puncture needle tube has a triangular pointed head and can be inserted into the puncture tunnel tube to accurately position the puncture point; the puncture needle core has a round blunt head and can be inserted into the puncture tunnel tube to make the needle head get closer to the target. When the utility model is used, the puncture tunnel tube is used for positioning, and then the puncture needle tube with the triangular pointed head is punctured through the skin and the triangular pointed head can be punctured accurately according to the preset angle and direction; when the ligamentum flava is punctured through, the puncture needle core with the round blunt head is continuously punctured in to ensure the round blunt head to reach the target as nearest as possible; in addition, the dural sac, the nerves in the spinal canal and the blood vessels are protected from being hurt, and the security of collagenase, ozone and anti-inflammatory analgesic in use is improved; meanwhile, impulse radio frequency or thermocoagulation can be conveniently operated through the puncture tunnel tube, thereby the difficulty of puncture is reduced and the effectiveness and the security of clinical therapy are improved.

Description

Spinal column puncture tunnel guide external member

Technical field

This utility model relates to the ache related puncture instrument of a kind of spinal column, especially relates to spinal column puncture tunnel guide external member.

Background technology

Ache related intervertebral disc source property pain, spinal canal stenosis, lumbar vertebra postoperative pain syndrome and the neural root pain etc. of generally including of spinal column.Present clinical spinal pain treatment technology comprises: the retardance of side crypts, Chemonucleolysis with collagenase, ozone ablation and the intervertebral disk hernia thing radio frequency target spot ablation that rises in recent years, laser vaporization ablation etc., the interventional therapy operation of above pain Wicresoft, all need puncture in the canalis spinalis and finish, because the outer lacuna of canalis spinalis endosclerite is narrow and small, add pathology own and degenerative change in the canalis spinalis, make the puncture procedure difficulty strengthen, the related complication that usually causes at present is mainly dural sac and wears out, arteriovenous damage in nerve root puncture associated injury and the canalis spinalis, have a big risk, to operator's specification requirement height, in recent years document have more collagenase be strayed into subarachnoid space cause the paralysis, ozone enters cerebrospinal fluid and forms aeroembolism, the nerve root mistake is worn, the case report of severe complication such as epidural hematoma and infection has greatly restricted these Clinical application.Now, through the inner edge puncture technique clinical practice of little joint more and more widely, this has technology can effectively be avoided needle point damage dural sac in the piercing process, neural root sheath and blood vessel, but still the tardy property subarachnoid space drug leakage that may exist, advocate that now the local anesthesia test needs to observe 20 minutes, bring certain misgivings for the clinical treatment secure context, the operation practical aspect, normally used common No. seven pins and radio frequency pin all exist as needle body soft partially, take place askew partially in the piercing process easily, inserting needle direction and angle are difficult for grasping, the problems such as positioning action that often need repeatedly puncture promptly increase the incidence rate of complication, have a strong impact on patient's operation ease again, increase the patient suffering, the more difficult grasp of abecedarian.

The utility model content

The purpose of this utility model is to provide a kind of accurate positioning, spinal column puncture tunnel guide external member safe and simple in structure of operating.

This spinal column puncture tunnel guide external member that this utility model provides, comprise puncture needle tubing, puncture nook closing member and puncture tunneltron, described puncture needle tubing is the triangle tip and can inserts in the puncture tunneltron, make puncture point orientation accurate, described puncture nook closing member is circular blunt nosed and can inserts in the puncture tunneltron, makes syringe needle more near impact point.

In order to control the position of point of puncture more well, the tube wall of described puncture tunneltron is marked with scale.

This utility model in use can be earlier with puncture tunneltron location, re-use the puncture needle tubing percutaneous puncture of triangle tip, the needle point of triangle tip can be accurately according to design point of view and direction are thrust in advance, after puncturing ligamenta flava, changing circular blunt nosed puncture nook closing member continues to thrust, circular blunt nosed needle point can be avoided nerve and blood vessel injury in dural sac and the canalis spinalis at utmost near target " target spot ", improves the safety that collagenase, ozone and anti-inflammatory analgesic liquid use.Can conveniently carry out pulse radiation frequency or heat operation with fixed attention by the puncture tunneltron simultaneously, reduce venipuncture difficulty, improve the effectiveness and the safety of clinical treatment simultaneously.

The specific embodiment

From Fig. 1 to Fig. 3 as can be seen, this spinal column of the present utility model pierces through the tunnel guide external member, comprise the puncture needle tubing 1 of a triangle tip, a puncture nook closing member 2 that circle is blunt nosed and a puncture tunneltron 3, puncture needle tubing 1 and puncture nook closing member 2 all can insert in the puncture tunneltron 3, puncture nook closing member 2 is long solid nook closing member, puncture tunneltron 3 is made by high strength steel, and its needle body and needle surface have lubricious, also indicates scale 31 on puncture tunneltron 3 tube walls.

This utility model in use, when especially little joint inner edge punctures into the road, earlier with puncture tunneltron 3 location, puncture needle tubing 1 with the triangle tip inserts wherein again, the puncture needle tubing 1 of this triangle tip can be accurately according to design point of view and direction are thrust in advance, after puncturing ligamenta flava, changing circular blunt nosed puncture nook closing member 2 continues to thrust, this needle point can be at utmost near target " target spot ", avoid nerve and blood vessel injury in dural sac and the canalis spinalis, improve the safety that collagenase, ozone and anti-inflammatory analgesic liquid use.Sometimes, can extract puncture nook closing member 2, radio frequency pin or condensation pin are inserted in the puncture tunneltron 3, can conveniently carry out the operation with fixed attention of pulse radiation frequency or heat.

Claims

1. spinal column puncture tunnel guide external member, it is characterized in that comprising puncture needle tubing (1), puncture nook closing member (2) and puncture tunneltron (3), described puncture needle tubing (1) also can insert in the puncture tunneltron (3) for the triangle tip, make puncture point orientation accurate, described puncture nook closing member (2) is circular blunt nosed and can inserts in the puncture tunneltron (3), makes syringe needle more near impact point.
