Description

Technical Field

[0001] The utility model relates to the field of puncture auxiliary instruments, in particular to a lung puncture positioning regulator. Background Art

[0002] Lung puncture not only requires precise positioning of the puncture point, but the direction and depth of the puncture also seriously affect the success rate of the puncture. For example, if the puncture is too shallow, the lesion cannot be reached; if the puncture is too deep, the lesion may be punctured deep into the normal lung tissue, which can easily cause complications such as pneumothorax and bleeding. Currently, a relatively accurate needle insertion depth can be obtained through a calibrated puncture needle and measurement under CT, but the direction of the needle insertion is difficult to grasp, and if the puncture direction is incorrect, the expected position cannot be reached. At present, punctures under CT guidance are mostly visually inspected, and CT is evaluated after puncture. Repeated punctures are required to accurately position the puncture needle, which will undoubtedly increase the puncture time and the CT scan radiation dose received by the patient, and increase the possibility of complications. In addition, during the puncture and aspiration process, small adjustments are required to the puncture needle to ensure that more lung tissue specimens can be aspirated during the small movement of the puncture needle. If the amplitude is too large or not well controlled, the puncture needle may easily withdraw from the lesion or penetrate the lesion during the aspiration process, causing damage to the lung tissue and leading to complications such as bleeding and pneumothorax, and reducing the positive rate of the puncture results.

DETAILED DESCRIPTION

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] The utility model is described in detail with reference to the accompanying drawings.

[0019] The utility model provides a lung puncture positioning regulator in a specific implementation, including a detachably connected base 1 and a pressing plate 4, wherein the base 1 is provided with a bonding portion 11 around it, the center of the base 1 is provided with a lower semicircular groove 2, the center of the pressing plate 4 is provided with an upper semicircular groove 5, the pressing plate 4 is installed above the base 1, the upper and lower semicircular grooves 2 of the base 1 and the upper semicircular groove 5 on the pressing plate 4 constitute a spherical placement cavity, a circular hole is provided at the bottom end of the spherical placement cavity, and an adjusting round head 7 is placed inside the spherical placement cavity;

[0020] The adjusting round head 7 is connected to an adjusting handle 8 , and a needle channel 9 is provided through the center of the adjusting round head 7 and the adjusting handle 8 for inserting a puncture needle.

[0021] Example:

[0022] During the specific implementation of the utility model, the doctor uses CT to perform cross-sectional positioning on the patient's chest, and determines the skin positioning point through the rib orientation and CT imaging of lung nodules. The skin positioning point is placed at the bottom rubber circular hole, and the base 1 is glued to the skin; the adjustment handle 8 is taken out from the circular hole of the pressing plate 4, and the buckle grooves 6 and the buckle columns 3 around are pressed to tightly connect the base 1 with the pressing plate 4, and the adjustment round head 7 is in the spherical gap formed by the base 1 and the pressing plate 4, and the extension rod 13 is connected to the tail end of the adjustment handle 8. At this time, the puncture needle is placed in the needle channel between the regulator and the extension rod 13, and it does not need to contact the skin.

[0023] The doctor can adjust the direction according to his own judgment for the first time. After the first positioning, the doctor can predict the direction of the puncture needle through CT according to the development of the puncture needle in the patient's CT, thereby avoiding unnecessary punctures; and when adjustment is needed, because there is no need to pull out the puncture needle as before, and because the friction between the round head 7 and the spherical gap is adjusted, a relatively fixed position can be maintained, which provides an objective basis for the doctor to adjust. When the puncture direction is determined, the extension rod can be screwed out and the puncture can be performed through the puncture needle with a scale. When fine-tuning is required, the use of the present invention can also provide a relatively objective basis, thereby improving the success rate of puncture.

[0024] Among them, through the installation and direction of the extension rod 13, a puncture point can be predicted.

[0025] As a further elaboration of the present invention, a plurality of anti-slip components 14 are distributed on the outer circumference of the adjusting round head 7 so as to keep the adjusting round head 7 in a fixed position in the spherical placement cavity.

[0026] As a further elaboration of the present invention, a threaded connection portion 10 is provided at the top of the adjusting handle 8, and the adjusting handle 8 is connected to an extension rod 13 through the threaded connection portion 10. A through hole corresponding to the needle channel is provided in the extension rod.

[0027] As a further elaboration of the present invention, the base 1 is provided with a plurality of buckle columns 3, and the pressure plate 4 is provided with a plurality of buckle grooves 6 that cooperate with the buckle columns 3. The base and the pressure plate are connected by the structure of the buckle columns and the buckle grooves, and the connection structure is simple and stable.

[0028] As a further explanation of the present invention, a floating area 12 is provided at one end of the bonding portion 11 on the base 1 to facilitate tearing and bonding the bonding portion 11 .

[0029] As a further elaboration of the present invention, the anti-skid component 14 on the adjusting round head 7 is one of anti-skid convex points or anti-skid strips. By distributing the anti-skid convex points or anti-skid strips on the adjusting round head, the friction between the adjusting round head and the spherical placement cavity can be increased, so that the adjusting round head can maintain a relatively fixed direction.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
