Problems solved by technology

However, for patients with obesity, anatomical variation, or doctors with insufficient clinical experience, repeated puncture failures are prone to occur, and at the same time increase the risk of surgery
In addition, since patients are mostly awake during minimally invasive surgery, repeated punctures are likely to cause tension and anxiety in patients, thus losing trust in doctors

Embodiment Construction

[0010] like figure 1 As shown, a puncture needle with a laser positioning light on the needle body includes a laser positioning light 1, a clip 2 and a puncture needle 3. The laser positioning light 1 is composed of a light source 11, a lamp body 12 and a switch 13. The clip 2 The laser positioning lamp 1 is connected with the puncture needle 3, and the puncture needle 3 is composed of a needle body 31, a needle core 32, a needle core base 321 and a needle wing 33.

[0011] During use, after the puncture needle 3 is pierced into the skin, the switch 13 of the laser positioning light 1 is pressed, and the light source 11 of the laser positioning light 1 emits a circular aperture, which is projected onto the image intensifier plane of the external C-arm X-ray machine. The light emitted by the light source 11 of the laser positioning lamp 1 is coaxial with the light emitted by the C-arm X-ray machine, that is, when the light emitted by the light source 11 of the laser positioning...

Abstract

The invention discloses a puncture needle provided with a laser positioning lamp on a needle body and relates to the field of medical apparatuses and instruments. The puncture needle structurally comprises the laser positioning lamp, a clamp and a puncture needle body, wherein the laser positioning lamp is composed of a light source, a lamp body and a switch, the clamp is connected with the laser positioning lamp and the puncture needle body, and the puncture needle body is composed of a needle body, a needle core, a needle core base and a needle wing. The puncture needle is simple in structure, low in cost and convenient to use, inversely projects an aperture signal to a C-shaped arm X-ray machine image intensifier plane by means of the laser positioning lamp and a 'coaxial technology' performing puncture guided by a C-shaped arm X-ray machine, guides a puncture path according to the change situation of an aperture projected on the image intensifier plane and brings convenience for accurate puncture.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a puncture needle with a laser positioning lamp on the needle body. Background technique [0002] With the improvement of living standards and the advancement of medical technology, minimally invasive surgery has become the preferred surgical method for many patients due to its advantages of less trauma, low cost, and quick recovery. For example: patients with trigeminal neuralgia receive C-arm X-ray machine-guided percutaneous puncture to the foramen ovale for radiofrequency thermocoagulation of the semilunar junction of the trigeminal nerve; patients with cervical spondylosis receive C-arm X-ray machine-guided percutaneous puncture to the foramen ovale Cervical nerve root anti-inflammatory and analgesic injection therapy in the intervertebral foramen; patients with lumbar disc herniation received C-arm X-ray machine-guided percutaneous puncture to the intervertebral disc for ther...
