Description

一种穿刺套件及可调型椎间盘切除刀套件 A puncture kit and adjustable knife set discectomy

技术领域 FIELD

[0001] 本发明涉及椎间盘切除刀技术领域,具体涉及一种穿刺套件及可调型椎间盘切除刀套件。 [0001] The present invention relates to a technical field discectomy tool, and particularly, to a puncturing kit adjustable discectomy tool kit.

背景技术 Background technique

[0002] 椎间盘是位于人体脊柱两椎体之间,分为中央部的髓核,富于弹性的胶状物质;周围部的纤维环,由多层纤维软骨环按同心圆排列;椎间盘上下端连接椎体的一层透明组织称之为软骨板,软骨板的一面与纤维环紧密连接,另一面则连接椎体,具有从上下方固护髓核的作用。 [0002] The intervertebral disc is located between two vertebrae of the human spine, into the central portion of the nucleus pulposus, resilient gel-like substance; annulus around the portion of the multilayered fibrous cartilage rings arranged concentrically; disc upper and lower ends a transparent connection vertebral tissue called cartilage, cartilage tightly connected to the annulus side, the other side is connected to the vertebral body, having a nucleus from below solid protection effect. 颈、腰部纤维环前厚后薄,髓核易向后外侧脱出,突入椎管或椎间孔,压迫脊髓或脊神经,造成椎间盘突出症。 Neck, the front waist thick thin annulus, nucleus prolapse easily rearwardly outward, broke into the spinal canal or intervertebral foramen, spinal cord or spinal nerve, resulting in disc herniation. 颈椎病和腰椎间盘突出症是最常见的外科疾病,多数病人虽可在早期经过非手术疗法如牵引、推拿等物理方法及药物治疗而使症状缓解,但仍有不少患者最终还需采用手术治疗。 Cervical spondylosis and lumbar disc herniation is the most common surgical disease, although most patients can go through non-surgical therapy in early traction, massage and other physical methods and medications to alleviate the symptoms, but there are still many patients eventually need surgical treatment. 在手术时,最明显的不足之处就是凿骨及刮除间盘时其深度难以掌握,稍有不慎或用力过大时极易造成脊髓损伤而引起严重后果。 At the time of surgery, the most obvious deficiency is the time between the chisel and scrape the bone plate difficult to grasp its depth, the slightest mistake or excessive force can easily result in serious consequences caused by spinal cord injury. 而经皮穿刺椎间盘切吸术中,穿刺时导针必须在X线的导引下才能定位,通过正、侧双向透视来调整进针方向和深度,手术要求很高,操作者要有相当的经验,并具有很大的盲目性和随意性。 And percutaneous discectomy, the puncture guide pin to be positioned under the guidance of X-ray, by adjusting the high positive-side perspective view of a two-way direction of the needle and the depth, surgical requirements, the operator must have considerable experience, and has great blindness and randomness. 另外,这类手术还需要辅助设备如X线机、显示器等,设备复杂,成本较高,一般医院难以具备这些条件。 Further, such operations need to auxiliary equipment such as X-ray machine, a display and other complex equipment, high cost, most hospitals have these difficult conditions.

[0003] 为了克服上述技术问题,申请人于1997年提出了申请号为97239805.8的中国实用新型专利申请,其记载了一种椎间盘切割刀外套管,在管柄上设有一带有刻度线的标尺,这个刻度线的零位与管柄的端面平齐。 [0003] To overcome the above technical problems, the applicant filed an application No. 97239805.8 of China utility model patent application in 1997, which discloses a disc cutter blade outer casing, a scale with tick marks provided on the tube handle , zero shank end surface of the tube flush with the tick. 这种外套管配合相应的手术器械,它能够准确地掌握切割刀等进入椎间盘的深度,定位准确。 This outer sleeve with the corresponding surgical instrument, it is possible to accurately grasp the depth of the cutting blade into the disc and the like, accurate positioning.

[0004] 上述椎间盘切割刀外套管需要配合刀具如内外旋切刀、螺旋刀等相应的手术器械进行切割,这些刀具的形状固定,无法根据手术的实际情况而调整最适合大小的刀口。 [0004] The disc cutting blade with the tool outer casing need surgical instruments such as the corresponding inner and outer rotary cutter helical cutting knives, the knives of the fixed shape, not the most suitable size is adjusted according to the actual surgical incision. 特别是在手术时,需要切除软骨板,再进行椎间融合技术,现有技术的椎间盘切割手术刀具不能调节刀具的大小,难以切除椎间盘的软骨板,无法进行椎间融合技术。 Particularly during surgery requires removal of cartilage, then interbody fusion, intervertebral disc surgery prior art tools can not adjust the size of the cutting tool, cutting hard disc cartilage, intervertebral fusion technology can not.

[0005] 因此,亟需对现有的椎间盘切割器组件加以改进。 [0005] Accordingly, an urgent need to improve the existing disc cutter assembly.
