Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a strap-on CT puncture marker. Background Technology

[0002] Patients with pulmonary nodules typically undergo biopsy localization under CT imaging. After determining the location before the puncture, a locator is used to mark the needle insertion point on the skin, and then the puncture is performed under aseptic conditions. Currently, the commonly used puncture markers are mainly metal positioning frames made by medical staff, consisting primarily of metal chains on both sides and multiple positioning metal strips in the middle. When using them, they are placed on the patient's skin and need to be secured with medical adhesive tape, which is inconvenient. If not secured, they are prone to slipping, causing inaccurate punctures. Furthermore, medical staff need to manually count the positioning points according to the positioning metal strips, which is cumbersome and prone to confusion.

[0003] Therefore, based on our long-term clinical experience with CT puncture, we have improved the existing metal positioning frame by combining it with Velcro straps and designing metal digital markers on one side of the positioning frame. The puncture positioning point can be quickly determined by the digital markers, and the positioning frame is easy to fix and adjust without the need for adhesive tape. This makes the operation convenient, improves the efficiency of clinical CT puncture, and is highly practical. Utility Model Content

[0004] The purpose of this invention is to provide a bandage-type CT puncture marker to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A strap-on CT puncture marker includes metal connecting chains on both sides, with multiple positioning metal strips evenly arranged between the metal connecting chains, and a connecting strap for binding the puncture marker to the patient's body surface. It also includes multiple metal digital markers corresponding to the positioning metal strips for marking different puncture positioning points.

[0007] As a further preferred embodiment of this utility model: connecting straps are connected to the positioning metal strips on both sides, and corresponding Velcro straps are provided on the connecting straps.

[0008] As a further preferred embodiment of this utility model: a non-metallic side strip is connected to one side of the metal connecting chain, and a metal numerical marker is provided on the non-metallic side strip.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This CT puncture marker combines a traditional positioning metal frame with Velcro straps, enabling rapid placement and fixation of the positioning metal frame on the patient's body surface. It also facilitates position adjustments, eliminating the cumbersome steps of using adhesive tape for fixation. Simultaneously, by setting a metal numerical marker on one side, medical staff can quickly determine the positioning point without counting the positioning metal strips, solving the problem of easily confused positioning points and improving the operational efficiency of clinical CT punctures. The design is scientifically sound and highly practical. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0018] Please see Figure 1-5This embodiment provides a strap-on CT puncture marker, including metal connecting chains 1 on both sides, with multiple positioning metal strips 2 evenly arranged between the metal connecting chains 1. The above structure is a conventional puncture marker structure familiar to those skilled in the art. In use, it is usually placed in the patient's chest cavity and fixed to the patient's skin with medical adhesive. Under CT imaging, medical staff determine the puncture positioning point by using a single positioning metal strip 2.

[0019] To improve the efficiency of CT puncture procedures in clinical practice, in this embodiment, the aforementioned CT puncture marker further includes a connecting strap 4. The connecting strap 4 is used to bind the puncture marker to the patient's body surface. Specifically, connecting straps 4 are connected to the positioning metal strips 2 on both sides, and corresponding Velcro 5 is provided on the connecting straps 4. As is common sense, the connecting strap 4 should not be a metal strap to avoid affecting CT imaging. It is preferably a conventional strap made of cloth, and its material will not be specified further in this application, but is a conventional choice familiar to those skilled in the art. The design of the connecting strap 4 eliminates the conventional adhesive fixing method, making it more convenient to fix and change the position of the puncture marker on the patient's body surface.

[0020] At the same time, in order to facilitate the confirmation of the puncture location point, such as Figure 2 As shown, it also includes multiple metal number markers 6 corresponding to the positioning metal strip 2. Specifically, a non-metallic side strip 3 is connected to one side of the metal connecting chain 1, and the metal number markers 6 are provided on the non-metallic side strip 3. As a conventional design, the non-metallic side strip 3 is preferably made of conventional materials such as plastic or cloth, so as not to affect development. This is a conventional choice and will not be described in detail. The metal number markers 6 are simply metal layers with corresponding numbers applied to the non-metallic side strip 3. The processing method is a conventional operation method and will not be described in detail in this application.

[0021] In addition, such as Figure 3 As shown, as a conventional option, the non-metallic side strip 3 can be in the form of a long strip or a single short strip structure. Its connection method with the metal connecting chain 1 is also a conventional design, which can employ binding, heat fusion bonding, or conventional snap-fit ​​connections, etc. The design and processing can be tailored to specific requirements, and this application will not elaborate further on the limitations.

[0022] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0023] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
