Technical Field

The invention belongs to medical auxiliary equipment, relates to a positioning and puncture auxiliary instrument used for round hole puncture under CT guidance in clinical treatment of trigeminal neuralgia (second maxillary neuralgia) radio frequency ablation, and particularly relates to a trigeminal dysmenorrheal round hole puncture radio frequency pen-holding type three-dimensional positioning puncture device which can fix a puncture point, ensure that the puncture point does not move in the puncture process, and accurately display the puncture angle and depth of the round hole.

Background

Trigeminal neuralgia refers to spontaneous or touch-induced, repetitive paroxysmal shock-like or lightning-like intense pain in the area of trigeminal innervation, referred to as "first-day pain". The pain parts are mainly located on the forehead, cheeks, and mandible, and can be induced by factors such as speaking, eating, washing face, brushing teeth, etc., which seriously affect the life quality of patients. Trigeminal neuralgia can be classified into primary and secondary, wherein the primary is more, the secondary incidence is lower, and the trigeminal neuralgia can be identified by related examination such as skull imaging. The trigeminal nerve is mainly divided into three branches, namely, the ocular branch (first branch), the maxillary branch (second branch), and the mandibular branch (third branch). Primary trigeminal neuralgia may affect one or more branches, with about 4% incidence in the first branch alone, about 17% incidence in the second branch alone, about 15% incidence in the third branch alone, and about 32% incidence in the second and third branches combined. The treatment of primary trigeminal neuralgia is preferably selected from antiepileptic drugs, such as carbamazepine. If the treatment is ineffective or the patient cannot tolerate the side effect of the medicament, the operation treatment is adopted, and comprises open-circuit microvascular decompression, balloon compression, percutaneous foramen ovale approach trigeminal nerve semilunar node radio frequency operation, chemical medicament injection destruction and the like. Wherein the percutaneous foramen ovale approach trigeminal semilunar node radio frequency operation is one of the most common minimally invasive surgery modes for treating trigeminal neuralgia, and an operator selects 2.5-3.0cm outside an affected side corner of a mouth as a puncture point, and a plane where a connecting line of the puncture point and an affected side pupil is located and a cross line of the puncture point and a plane where a connecting line in front of an affected side external ear hole is located are taken as puncture directions. The method is used for more than 100 years, but the needle point position of the puncture needle needs to be repeatedly adjusted in the puncture process, so that the operation time is uncontrollable. In addition, repeated intracranial burley punctures may be required during the procedure, with significant risks of intracranial bleeding, infection, and nerve injury.

In recent years, scholars suggest to treat the second branch pain of the trigeminal nerve by adopting zygomatic arcade entry puncture round hole radio frequency operation, the radio frequency target point of the second branch pain of the trigeminal nerve is changed into a round hole from the semilunar junction and is transferred from the intracranial space to the extracranial space, thereby reducing the risks of intracranial hemorrhage, intracranial infection, nerve injury and the like and improving the safety.

Nevertheless, there is a continuing improvement in the treatment of trigeminal second pain via subzygomatic access puncture round hole radio frequency. A puncture three-dimensional positioning device consisting of a semicircular protractor, a level gauge and a base is adopted in previous clinic to assist the positioning and puncture of a circular hole under the guidance of a CT, a radio frequency puncture needle adopted in previous clinic is thin, an operator is inconvenient to directly hold the puncture needle, the puncture depth cannot be displayed, and a fixed puncture point device is lacked. In addition, because the positioning device and the puncture needle are separated, an operator needs to operate the left-hand-held semicircular three-dimensional positioning device and the right-hand-held puncture needle in a matching manner, and CT scanning may need to be repeatedly performed to determine the puncture depth in the scanning process. All the above factors prolong the puncture operation and operation time.

The needle core 10 has a length of 18cm and an inner diameter of 0.3cm, and the bevel tip of the original needle core is reserved. A propeller 4 is arranged at a position 18cm away from the tip of the penholder body 2, the propeller 4 is positioned in a circle with the diameter of 0.5cm in the cavity of the penholder body 2, a conical protrusion with the diameter of 0.2cm and the height of 0.2cm is arranged below the circle, and the conical protrusion is matched with a conical depression with the diameter of 0.2cm and the height of 0.2cm at the top of the tail end of the handheld handle 11; the side end of the propeller 4 is exposed outside the pen holder body 2 to serve as a finger contact part 7, the pen holder body 2 on one side of the finger contact part 7 is provided with a vertical concave gap serving as a downward moving track (with the width of 0.2cm) of the finger contact part 7, the upper end of the track is connected with the pen holder connecting block 13, the lower end of the track is connected with the threaded connection part 6, and the propeller 4 cannot move downward after being pushed to the threaded connection part 6. The thruster 4 is provided with a thruster bayonet 8 which can clamp a conical hand-held 11 and is used for fixing the radio frequency puncture needle 3 during puncture; after the pusher bayonet 8 is fixed on the hand-held handle 11, the radio frequency puncture needle 3 is pushed to move towards the tip direction by moving the finger contact part 7 downwards.
