The invention discloses a puncturing guidance input system for cement injection reinforcing for sick vertebra of spinal metastatic tumor open surgery. The puncturing guidance input system comprises aguidance threaded bolt, an axial paracentesis trocar, an oblique puncturing guiding device, an oblique paracentesis trocar and a guiding pin, wherein a middle axle passage is arranged in the axial direction of the guidance threaded bolt; a longitudinal near end open slot and a longitudinal far end open slot are formed in the guidance threaded bolt; the longitudinal far end open slot is formed in the circumferential opposite sides of the longitudinal near end open slot; a control rod is arranged behind the guidance threaded bolt; the oblique puncturing guiding device comprises a connecting sleeve and a guiding curved arm which are in corner connection; the connecting sleeve is used for being connected with the control rod; a sliding block is arranged on the guiding curved arm; the guiding sleeve penetrates through and is fixed to the sliding block, and slides along the guiding curved arm along with the sliding block; the oblique paracentesis trocar cooperates with the guiding sleeve; and one or more openings are formed in the front end of the oblique paracentesis trocar / the axial paracentesis trocar. The puncturing guidance system can realize high-efficiency, low-risk and low-cost perfusion and stuffing of bone cement under the open surgery.
Description
technical field [0001] The invention belongs to the technical field of orthopedic medical devices, and in particular relates to a puncture-guided input system for vertebral cement perfusion strengthening of spinal metastatic tumor open operation disease. Background technique [0002] At present, two methods are mainly used for bone cement perfusion and / or filling during open surgery for spinal metastatic tumors. However, there are various degrees of defects in the following two ways. [0003] The first type is bone cement perfusion enhancement system. These systems currently use minimally invasive percutaneous vertebroplasty. This type of bone cement perfusion enhancement system is usually operated with a single puncture needle and a cannula, and the bone cement overflows at the tip of the input tube during perfusion. Specifically, after resection and decompression of the posterior structure of the diseased vertebra, the puncture needle is inserted into the diseased verte...
