Device and method for preparing fibula near-end bone tumor focus removing guider

Abstract

The invention relates to a fibula near-end bone tumor focus removing guider and a preparation method thereof. The fibula near-end bone tumor focus removing guider comprises a patient CT (Computed Tomography) scanning film, a bone reconstruction device, a guider construction device and a 3D (Three-dimensional) printer, wherein a CT scanning film reading port is formed in the input end of the bone reconstruction device; the patient CT scanning film is arranged in the CT scanning film reading port; a CT scanning film data analysis module is arranged in the bone reconstruction device; the output end of the CT scanning film data analysis module is connected with the input end of the guider construction device; the output end of the guider construction device is connected with the input end of the 3D printer. By directly utilizing a digital visualization bone tumor focus guider 3D printing working platform designed in the invention, a clinician inputs the CT data information of a surgical patient, a guider can be designed and prepared, the surgical accuracy is greatly improved, and the surgical risk is reduced.

Description

technical field [0001] The invention belongs to biology and new medical technology, and in particular relates to a preparation device and method of a fibula proximal bone tumor lesion removal guide. Background technique [0002] For bone tumor surgery, due to the different locations, types, and sizes of tumors in patients, the surgical methods vary greatly, and in addition to the differences in age, body shape, and physical fitness among patients, it is very necessary to perform one-on-one individualized surgery for patients. design. Modern computer technology provides a good working platform for preoperative design, enabling orthopedic surgeons to easily carry out digital and precise surgical design, but it is a difficult problem to accurately restore the preoperative design and apply it to actual surgery. With the popularization and use of 3D printing technology, the design and manufacturing process of surgical guides based on 3D printing technology came into being. Su...

Problems solved by technology

But there are the following disadvantages: ① At the patient level, shrinkage occurs during the curing process of the resin, which inevitably generates stress or causes deformation, so the precision of the manufactured guide is low

The screw placement error caused by the accuracy of the guide may cause arterial injury to the patient; ② At the hospital level, the SLA system is expensive, and its use and maintenance costs are too high. Most domestic hospitals cannot obtain such high-priced industrial-grade manufacturing equipment , even if the equipment is purchased, the human and economic costs of maintaining the equipment are quite high, so it cannot be promoted in domestic hospitals; ③ At the doctor level, the SLA system is a precision equipment that operates on liquids, and has strict requirements on the working environment and many molded parts It is a resin, with limited strength, stiffness, and heat resistance, which is not conducive to long-term storage, so it is a huge challenge for doctors during the preparation of the guide

④ On the level of engineering technology, preprocessing software and driver software have a large amount of calculations, are too highly correlated with processing effects, and the operation of the software system is complicated. The preparation of the guider entity requires special personnel to operate and maintain it. Requires repeated design discussions with orthopedic surgeons, consuming a lot of time

The deficiencies of the above-mentioned levels determine that this technology cannot be widely applied clinically at present.
