Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an in vitro auxiliary positioning membrane. Background Art

[0002] CT-guided interventional technology is a relatively safe, reliable, simple and quick minimally invasive treatment technology.

[0003] Since CT scans can obtain high-resolution images, they can clearly display the cross-sectional anatomy of the puncture plane in the patient's body, accurately show the location, size, shape, internal condition of the lesion and its spatial relationship with surrounding structures, especially the distribution and course of adjacent blood vessels and nerves. During puncture, it can also scan and observe the specific position of the needle, and try to avoid important tissues and organs in the body along the puncture path to improve the accuracy of the puncture and avoid damaging important structures in the body.

[0004] In the existing technology, when the CT machine is examining the patient's area, there is no precise positioning mark on the patient's area. When the CT machine is removed, medical staff cannot accurately restore the position and size information of the patient's area. Before puncture, the position of the puncture point, the direction of needle insertion and the depth cannot be accurately determined, which can easily cause deviations in subsequent puncture treatment.

[0034] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other in the absence of conflict.

[0035] Example 1:

[0036] According to the concept of this application, Figures 1 to 2The following describes an embodiment of an in vitro auxiliary positioning membrane for assisting patient positioning during CT scans. Specifically, the in vitro auxiliary positioning membrane is constructed as an integrated structure and comprises four components: a carrier layer 1, a positioning ball 5, an adhesive layer 6, and a protective film 7. The positioning ball 5, the carrier layer 1, the adhesive layer 6, and other structures interact to produce multiple evenly spaced point artifacts on the CT scan image. Using the unit length between adjacent point artifacts, a specific part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.

[0037] Combine Figure 1-3 As shown, the utility model provides an in vitro auxiliary positioning membrane, comprising:

[0038] The carrier layer 1 has a plurality of longitudinal positioning lines 2 and transverse positioning lines 3 on its top surface, and positioning holes 4 are formed at the intersections of the longitudinal positioning lines 2 and the transverse positioning lines 3;

[0039] Positioning ball 5, which is installed in positioning hole 4 through medical glue 8;

[0040] The adhesive layer 6 is provided below the supporting layer 1, and the positioning balls 5 are arranged through the adhesive layer 6;

[0041] The protective film 7 is arranged on the outer surface of the adhesive layer 6 .

[0042] According to the technical solution of this embodiment, the bearing layer 1 is made of non-woven fabric, and the bearing layer 1 can provide support for the positioning ball 5.

[0043] The positioning ball 5 is a solid ball. In some embodiments, the material of the positioning ball 5 can be set to ceramic or glass. For the technical solution of this embodiment, the material of the positioning ball 5 is set to glass. When X-ray irradiation is performed, since the density of glass is greater than that of human bones, multiple evenly distributed point artifacts can be generated in the CT scan. By using the unit length between adjacent point artifacts, a certain part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.

[0044] According to the technical solution of this embodiment, the shape of the positioning ball 5 is set to be spherical, and the diameter of the positioning ball 5 is 2-3 mm.

[0045] According to the technical solution of this embodiment, the adhesive layer 6 is made of medical adhesive, the protective film 7 is made of thin film material, the positioning ball 5 is arranged through the protective film 7, and the protective film 7 is used to protect the adhesive layer 6.

[0046] There is at least one unit length between adjacent longitudinal positioning lines 2 or adjacent transverse positioning lines 3. According to the technical solution of this embodiment, there is one unit length between the longitudinal positioning line 2 and the transverse positioning line 3. The unit length is not limited here and can be selected according to actual needs. For example, one unit length is 1CM.

[0047] It should be noted that the size of the in vitro auxiliary positioning membrane is not limited here and can be cut according to the specific location.

[0048] Specifically, when auxiliary positioning is needed, first tear off the protective film 7, and use the adhesive layer 6 to stick the supporting layer 1 and the positioning ball 5 to the scanning part of the patient. Since the density of glass is greater than that of human bones, multiple evenly distributed point artifacts can be generated in the CT scan. By using the unit length between adjacent point artifacts, a certain part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.

[0049] The following further describes an in vitro auxiliary positioning membrane provided by the present invention in conjunction with the accompanying drawings and implementation examples.

[0050] An in vitro auxiliary positioning membrane, comprising:

[0051] The carrier layer 1 has a plurality of longitudinal positioning lines 2 and transverse positioning lines 3 on its top surface, and positioning holes 4 are formed at the intersections of the longitudinal positioning lines 2 and the transverse positioning lines 3;

[0052] Positioning ball 5, which is installed in positioning hole 4 through medical glue 8;

[0053] The adhesive layer 6 is provided below the supporting layer 1, and the positioning balls 5 are arranged through the adhesive layer 6;

[0054] The protective film 7 is arranged on the outer surface of the adhesive layer 6 .

[0055] Example 2:

[0056] Combine Figure 3 As shown, the fundamental difference between Example 2 and Example 1 is that the shape of the positioning ball 5 is set to be an ellipsoidal sphere, and the long diameter of the positioning ball 5 is 2-3 mm, and the short diameter is 1-2 mm. The ellipsoidal positioning ball 5 is easier to fix in the positioning hole 4 than the spherical one.

[0057] Example 3:

[0058] Combine Figure 4As shown, the fundamental difference between the second embodiment and the first embodiment is that: the distance between two adjacent longitudinal positioning lines 2 is two unit lengths, and the distance between two adjacent horizontal positioning lines 3 is one unit length. The unit length is not limited here and can be selected according to actual needs. For example, one unit length is 1CM.

[0059] The working principle and usage process of the present invention are as follows: when auxiliary positioning is required, the protective film 7 is first torn off, and the supporting layer 1 and the positioning ball 5 are pasted to the scanning part of the patient using the adhesive layer 6. Since the density of glass is greater than that of human bones, multiple evenly distributed point artifacts can be generated in the CT scan. By using the unit length between adjacent point artifacts, a certain part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.
