Description

A guide fixer for CT navigating puncture biopsy

technical field

The utility model relates to a guide fixer for CT navigation puncture biopsy, which is used for percutaneous puncture biopsy of patients under CT scanning navigation, and belongs to the technical field of medical supplies.

Background technique

At present, needle biopsy has been widely carried out abroad, and the puncture site covers all other tissues in the whole body except blood vessels. In recent years, with the popularization of the concept of precision medicine, domestic hospitals have gradually carried out needle biopsy. CT-guided percutaneous biopsy is a relatively safe, simple, and highly accurate diagnostic method. It can obtain pathological tissue with minimal trauma, and the nature of the lesion, the specific cytological type and differentiation of the tumor can be understood through pathological detection. It can also clarify the type of pathogenic bacteria, provide sufficient and accurate evidence-based medical basis for precision medicine and individualized medicine, and better serve patients.

Compared with other puncture techniques, CT-guided percutaneous biopsy has the following advantages: 1. CT scanning has high spatial resolution and clear images; 2. It is not interfered by hollow organs, gas and bones; 3. CT-enhanced images and The three-dimensional reconstruction image can clearly show the spatial relationship between the lesion and the surrounding tissue structure; 4. There are relatively few surgical complications; 5. The success rate of biopsy tissue is high.

CT scanning can fully display the spatial position of the patient's lesion, which is beneficial to guide the direction of puncture and the depth of needle insertion. Puncture needles and biopsy guns are currently available on the market, but in actual puncture operations, when soft tissues such as thoracic and abdominal muscles are thin, it is difficult to fix the puncture needle, resulting in the direction of the puncture needle shown on the CT scan and the actual ideal puncture Inconsistent directions reduce the success rate of biopsy and increase the risk of puncture damage to surrounding important tissue structures, so a guiding fixator is required during puncture.

Contents of the invention

The purpose of this utility model is to provide a puncture guide fixer to improve the convenience of operation and the success rate of puncture biopsy, and solve the above-mentioned problem in puncture operation, that is, the direction of the puncture needle displayed by CT scanning is inconsistent with the actual puncture direction.

In order to achieve the above purpose, the utility model provides a guide fixer for CT navigation puncture biopsy, which is characterized in that it includes a base that can be fixed on the patient and a guide fixation rod for guiding the puncture needle. The base and the guide fixed rod are connected by a ball hinge.

Preferably, the base can be adhered to the patient's skin.

Preferably, two sides of the base are provided with two slots allowing cloth straps to pass through, and the cloth straps can pass through the slots to fix the base on the patient.

Preferably, the guiding and fixing rod has two sections, one of which can expand and contract in the axial direction.

Preferably, the end of the guiding and fixing rod is provided with a groove for supporting the puncture needle, and the puncture needle is arranged in the groove.

More preferably, the cross-section of the groove is semicircular.

More preferably, the groove is arranged along the axial direction of guiding the fixing rod.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model is easy to operate, can guide and fix the puncture needle, and improves the success rate of puncture biopsy.

detailed description

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

Example

As shown in FIG. 1 , the guide fixer for CT navigation puncture biopsy of the present invention includes a base 1 that can be fixed on a patient and a guide fixation rod 4 for guiding a puncture needle.

The base 1 can be pasted on the patient's skin, and the two sides of the base 1 are respectively provided with two grooves 2 that allow cloth belts to pass through, and the cloth belts can pass through the grooves 2 to fix the base 1 on the patient.

The base 1 and the guiding and fixing rod 4 are connected by a ball hinge 3, so that the guiding and fixing rod 4 can be three-dimensionally adjusted according to the puncture angle under the CT scan, so that the direction of the puncture needle is consistent with the puncture angle under the CT scan . The guiding and fixing rod 4 has two sections, one section 5 of which can expand and contract in the axial direction, so as to be suitable for different puncture needle lengths.

As shown in Fig. 2 and Fig. 3, the end of described guide fixed rod 4 is provided with the groove 6 that is used to support puncture needle, and the cross section of groove 6 is semicircle, and groove 6 is along the axis of guide fixed rod 4 to the settings. The puncture needle is located on the upper side of the guide fixing rod 4 and is arranged in the groove 6 .

During use, according to the condition of the patient and the puncture site, select the above two fixing methods to fix the base 1 on the patient. After adjusting the angle of the guiding and fixing rod 4, the puncture needle is erected in the groove 6, and the puncture biopsy can be performed.
