Embodiment 1

[0017] The method for using the vector positioning and puncture assist device involved in this embodiment includes a fixed base 1, a sagittal mark line 2, a coronal mark line 3, a long strip hole 4, a slideway 5, and a spherical through hole with the help of a main structure. 6. Spherical angle holder 7, puncture needle fixing tube 8, angle holder base 9, hollow outer tube needle 10, hollow outer tube needle base 11, inner core needle safety valve 12, inner core needle 13 and inner core needle boost The positioning and puncture fixing device of the end 14 is realized. The steps include (1) determining the surface puncture point, puncture angle and needle depth, (2) positioning the puncture fixing device, adjusting the position and angle of the puncture needle, (3) pushing the needle, (4) ) Four steps to remove the outer tube needle and fixing device:

[0018] (1) Determine the surface puncture point, puncture angle and needle depth: take the number of intercostals as the horizont...

Embodiment 2

[0025] The method of using the vector positioning and puncture assisting device involved in this embodiment has the same operation steps as in Example 1. The material of the core needle 13 of the positioning and puncture device for implementing this method is PGA which can absorb medical materials to avoid leaving residues in the tissue Things affect the success of the operation.

Embodiment 3

[0027] The method of using the vector positioning puncture assist device involved in this embodiment is the same as that of the first embodiment. The method of using the assist device is used for medical teaching or medical learning drills, operating on dead human or animal bodies, or teaching props Internship operations are carried out to improve the operational level of medical staff.

Abstract

The invention belongs to the technical field of medical instruments, and relates to a using method of a vector positioning puncture auxiliary device. The intercostal number is taken as a horizontal axis, seven body surface marking lines of a body surface sternum line, a clavicle midline, an anterior axillary line, a midaxillary line, a posterior axillary line, a scapular line and a posterior median line are taken as vertical axis, scan data are analyzed based on a chest CT scan image, the maximum cross-sectional image of a target point is taken to determine the intercostal number and the bodysurface marking lines which are similar to the maximum cross-sectional image, the intercostal number is the puncture intercostal number, the parallel distance between a puncture position of the maximum cross-sectional image of the closest body surface marking line is measured to determine a body surface puncture point, the center of the target point and the puncture point are connected on the maximum cross-sectional image of the target point to determine the puncture angle, and the distance between the body surface puncture point and the target point is measured as the inserting depth of the puncture needle. The puncture accuracy is improved, the work intensity of doctors is reduced, the radiation damage of the doctors and patients is reduced, the method is simple and easy to operate, safeand reliable, good in versatility, easy to operate and popularize and friendly in application environment.

Description

Technical field: [0001] The invention belongs to the technical field of medical equipment, and relates to a method for using a vector positioning and puncture auxiliary device, in particular to a vector positioning auxiliary positioning fixation with intercostal number as the horizontal axis and seven body surface marking lines as the vertical axis. The method of using the puncture device is especially suitable for small-area target puncture positioning. Background technique: [0002] Before surgical treatment of small pulmonary nodules, it is necessary to locate the target first, and then perform subsequent operations. The accuracy of the determined target directly affects the difficulty and success rate of the subsequent surgical process; currently, the determination of the target Common methods are CT-guided puncture needle positioning or placement of spring coils, etc. The body surface calibration puncture point and puncture process must be performed in the CT room to observe...
