The invention discloses a puncture guide input system for spinal metastatic tumor open operation disease vertebral cement perfusion reinforcement, which comprises: a guide thread bolt, an axial puncture trocar, an oblique puncture guide device, and an oblique puncture sleeve A needle and a guide pin; a central axis channel is provided along the axial direction of the guide thread bolt; a longitudinal proximal slot and a longitudinal distal slot are arranged on the guide thread bolt; the longitudinal distal slot is arranged on the longitudinal proximal slot On the opposite side of the circumference; behind the guide threaded bolt is a handle bar; the oblique puncture guide includes a connecting sleeve and a guide arc arm connected by a corner; the link sleeve is used to connect with the handle bar; the guide arc arm is provided with a slide The guide sleeve passes through and is fixed on the slider, and slides along the guide arc arm together with the slider; the oblique puncture trocar matches the guide sleeve; the oblique puncture trocar / axial puncture trocar The front end of the needle is provided with at least one opening. The puncture guide system can realize high-efficiency, low-risk, and low-cost perfusion filling of bone cement under 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...
