Embodiment 1

[0025] Embodiment 1: In this embodiment, the technical solution of the present invention is specifically described by using a navigation template for inserting pedicle screws through personalized auxiliary small incisions for L3 and L4 double vertebral segments.

[0026] The navigation template for placing pedicle screws in the personalized auxiliary small incision includes two sets of screw-setting components, each set of screw-setting components includes two bottom plates 1 arranged on both sides of the vertebral segment to be screwed, respectively fixed on the The two nail-introduction guide tubes 2 on the base plate 1, and the transverse arc-shaped connecting rods 3 respectively fixed on the two ends of the nail-introduction guide tubes 2, the base plate 1 is reversed according to the anatomical structure of the spine around the position of the patient's nail-entry point. Generated, the nail entry catheter 2 is connected to the base plate 1 according to the calculated accur...

Abstract

The invention discloses a personalized navigation template for assisting small incisions to insert pedicle screws, which includes at least one set of screw components, and each set of screw components includes two symmetrically arranged on both sides of the spinal segment to be screwed. A base plate, and two nail-introducing conduits respectively fixed on the base plate, the structure of the base plate matches the anatomical structure of the spine around the nail point to be placed, and the nail-introducing guide tubes are determined by the calculated and reasonable nail placement channel , and connected to the backplane. The present invention is connected to the base plate with a nail-introducing catheter determined by a calculated and reasonable nail-inserting channel, which can ensure the accuracy of nail-inserting and the safety of surgery without fluoroscopy, and reduces the radiation exposure of medical staff and patients.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the field of pedicle screw placement. Background technique [0002] Pedicle screw technology is widely used in spinal trauma, degeneration, tumor and other diseases, and can achieve good fixation effect. At present, the commonly used pedicle screw technology mainly includes manual screw placement, C-arm machine fluoroscopy screw placement, CT navigation-assisted screw placement, etc. These screw placement methods have disadvantages such as poor safety, more fluoroscopy, and high price. In recent years, the small-incision pedicle screw technique has become more and more popular among doctors and patients because of its advantages of less trauma, less bleeding, and faster recovery. However, it puts forward higher technical requirements for the operator. To ensure the safe and accurate completion of small incision surgery, the surgical process must be completed under C-arm machin...
