Abstract
The utility model discloses a medical CT guided focus puncture biopsy positioning gauge, which comprises a vertical gauge, a horizontal gauge and a rail for fixing the two gauges; the original end of the vertical gauge can be adhered with 90 degrees goniometer, the end point of the vertical gauge is provided with a mark point, under the CT guidance, the focus (in particular to small focus)in body can be determined accurately by adopting three-step acupuncture, so as to reach accurate positioning for puncture biopsy and lower puncture risk, thereby being advantageous for clinic diagnosis and therapy.
Description
This utility model relates to a kind of CT guiding servant internal lesions localised puncture positioning rule, is particularly suitable for the localised puncture art of small lesion in the body.
CT guiding internal lesions aspiration biopsy down has been widely used, and common method is that this method has following shortcoming: 1, internal lesions is less with lattice location, self-control body surface location, and hour location is accurate inadequately with breast, adhesion of abdominal wall; 2, in case the inaccurate sterile interface once more that needs of puncture.
The purpose of this utility model provides a kind of people's internal lesions puncture positioning rule, improves internal lesions puncture positioning accuracy, is particularly suitable for the puncture location of small lesion in the body; Simplify positioning action, reduce the puncture risk.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof:
Fig. 1 is that the CT that the utility model proposes guides the front view that servant's internal lesions punctures positioning rule.
Describe CONSTRUCTED SPECIFICATION and working condition in detail below in conjunction with Fig. 1 according to the concrete positioning rule that the utility model proposes.
This positioning rule comprises a horizontal chi (1), a longitudinal ruler (2), and they are fixing by a track card (3) each other, and track card (3) makes that horizontal chi (1) and longitudinal ruler (2) are vertical mutually also can be moved mutually.Laterally chi (1) and longitudinal ruler (2) length, width, thickness are respectively 40 centimetres, 3.5 centimetres, 0.3 centimetre.Longitudinal ruler (2) top attaches the goniometer (4) of one 90 degree, and longitudinal ruler (2) end points is with one 2 * 2 millimeters
2Gauge point (5) in order to last color marker, generally uses gentian voiet.Laterally chi (1) and longitudinal ruler (2) scale are accurate to the millimeter level.The positioning rule material is lucite.Available general medicining liquid dipping.
The method step of implementing localised puncture with this utility model people internal lesions puncture positioning rule is:
The first step: select best puncture aspect.CT scans focus after drawing spacer, selects a best aspect (nearest apart from body surface, puncture path is accessible and the maximum aspect of important blood vessels and nerve, focus and breast adhesion of abdominal wall).
Second step: utilize the CT vernier to simulate best inserting needle route.Referring to Fig. 2, inserting needle route and skin intersection point are point of puncture C.Point of puncture to focus center O distance is depth of needle OC.Utilize the CT software for calculation to calculate needle angle (with losing shape face or coronalplane) angle C simultaneously.
The 3rd step: determine point of puncture.Utilize the CT vernier to make a vertical line BC along the simulation point of puncture, make the horizontal tangent AB of a sagittal plane along front wall (or rear wall) to vertical line, measure AB, BC length respectively, with the horizontal chi of positioning rule and the longitudinal ruler length of fastening AB, BC respectively, keep flat along center line along the best puncture of focus plane scan position line crossfoot (AB section) initiating terminal, then ruler (BC section) initiating terminal summit drop point is point of puncture C.The former colouring gauge point point that presets is on skin.According to the angle C number of degrees that calculate, reference location chi goniometer is grasped needle angle.Local anaesthesia and syringe needle put this aspect of multiple scanning on the simulation puncture route of staying after the partly sterilised confirms that entry point and angle tailing edge needle position, direction thrust the aspiration biopsy tissue with puncture needle by fathoming.
Claims (3)
1, CT guiding internal lesions puncture positioning rule down, this chi is by a horizontal chi (1) and a longitudinal ruler (2) and track card (3) the formation main body of fixing two rulers; Track card (3) makes horizontal chi (1) and longitudinal ruler (2) vertical mutually and can move mutually, and horizontal chi (1) and longitudinal ruler (2) length are 40 centimetres; The longitudinal ruler initiating terminal has the 90 degree goniometers that can attach.
