Abstract

A CT-guided puncture body surface positioning grid is an appliance which displays the spatial positions of a plurality of mark points on the body surface of a human body fault through CT scanning; the CT developing film is formed by a special CT developing sheet through die pressing, the shape of the CT developing film is square or rectangular, a frame (B) is arranged outside the CT developing film, more than one developing strip (A) is arranged inside the CT developing film, n (n is 1, 2, 3 …) developing strips (A) are arranged longitudinally at equal intervals in parallel in a regular mode, and two ends of the developing strips are connected to the frame (B); the double-sided adhesive is adhered to the lower surface of the frame (B), so that the frame is convenient to fix in use; the development bar (A) is provided with scale marks so as to be matched with the fault indicating line to be quickly adjusted and positioned in the longitudinal direction; when the positioning grid is used, the longitudinal developing strip (A) is adhered to the long axis of the human body in the forward direction.

Description

CT guide puncture body surface positioning grid

The technical field is as follows:

the utility model relates to a positioning mark formed by CT scanning and imaging on the body surface of a human body, in particular to a device for CT guided puncture of the positioning mark on the body surface.

Background art:

with the development of image and computer software technologies, the clinical application of precision medicine is increasing, and the core of the technology is the "precision guidance technology" under the guidance of images. The 'guidance' needs to make some image marks on the body surface of the human body, the marks have double visuality of images and objects, and are important reference marks for measuring the space position of a lesion and a certain point on the body surface, so that the lesion can not be seen by naked eyes when the deep part in the human body is accurately punctured through a percutaneous fixed point. At present, although some people utilize a plurality of high-density metal wire parallel arrangement adhesive tapes to be fixed together to serve as a positioning puncture mark of a CT (computed tomography), certain convenience and accuracy are brought, the mark manufacturing assembly is irregular, the fit degree with skin is poor, the operation is complex during use, the mark is easy to deform, the repeated use is easy to cross-infect, and the like. Clinically, a special paperboard with moderate softness is needed, CT scanning imaging development is good, the special paperboard is molded into an integral body surface positioning grid, a double-faced adhesive tape is adhered to the lower frame of the positioning grid, and scale marks are marked on the upper positioning grid. Through retrieval, the CT guided puncture body surface positioning grid is not found.

The invention content is as follows:

an object of the utility model is to provide an wholeness can be good, and CT scanning formation of image develops obviously, and convenient to use is good with the body surface laminating degree, seeks the setpoint swift, and comparatively accurate location mark sex utensil.

The utility model discloses a realize like this, it is mainly accomplished by two steps, and firstly, preparation CT develops the card paper, secondly becomes the location bars with the card paper mould pressing.

The CT developing card paper is made by rolling thick paper pulp into a thin sheet with the thickness of 1-2 mm and drying the thin sheet. The paper pulp is made up by using high-density mineral powder, excipient, adhesive, wood pulp and water through a certain mixing process. The CT development density is adjustable and is determined by the proportion of mineral powder, excipient and wood pulp. The specially-made developing paperboard is moderate in softness, not easy to crack when bent, obvious in development, free of imaging artifacts and good in skin fitting degree.

A CT developing card paper with a proper size is selected and is pressed and cut into a CT guiding puncture positioning grid under a molding press. The double-sided adhesive tape is adhered to the lower frame of the positioning grid, and the scale lines are printed on the upper frame of the positioning grid, so that the perfect CT guided puncture body surface positioning grid is formed. The utility model discloses the wholeness can be good, facilitates the use.

Drawings

FIG. 1 is a schematic diagram of the structure of the present invention;

fig. 2 is a sectional application pattern diagram of the present invention.

In the figure: a-developing strip, B-frame, C-double faced adhesive tape, D-scale line, E-tomographic image, F-pathological change and G-puncture point.

The specific implementation mode is as follows:

the following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings: the CT-guided puncture body surface positioning grid is a sheet-shaped structure body formed by die cutting a piece of CT development paperboard, is square or rectangular as a whole, is internally provided with more than one development strip (A), is provided with n (n is 1, 2, 3 …) development strips, is arranged in a longitudinal equidistant and parallel rule, is connected with two ends of the development strip on a frame (B), and has the width of 1-2 mm. The double-sided adhesive tape (C) is arranged below the frame (B) for adhering, so that the positioning grid can be conveniently fixed on the body surface. The scale marks (D) with the interval of 5 mm or 10 mm are transversely printed on the positioning grid, so that the skin can be quickly measured and determined when the puncture point is adjusted in the longitudinal direction.

The specific application method of the utility model comprises the following steps: taking the upper abdominal liver area lesion as an example, performing CT-guided needle biopsy on the lesion, firstly removing a release paper of a double-sided adhesive tape below a CT-guided puncture body surface positioning grid, tiling and covering the positioning grid on the body surface to be punctured of the right upper abdomen of a patient, adhering a double-sided adhesive tape (C) below a frame (B) on the skin, enabling a developing strip (A) to be parallel to the long axis of the human body, performing CT transverse scanning, and examining the lesion (F) in a sectional image (E); determining a puncture point (G) on the skin as good based on the doctor's assessment of the puncture path of the lesion (F) on the tomogram (E); the puncture point (G) is positioned between 3 and 4 of the developing strip (A), and parameters between the puncture point and the position of the developing strip (A) can be accurately measured; the laser indicating line of the CT machine is adjusted to the fault (E), and the puncture point (G) can be found on the solid skin quickly according to the laser indicating line, the developing strip (A) and the space position parameters of the puncture point (G).
