Description

Puncture auxiliary positioning device
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a puncture auxiliary positioning device.
Background
At present: under the condition of the prior art, technologies such as puncture aspiration of abdominal organ cyst and tumor radiofrequency ablation are often required to be performed under the guidance of CT. Considering the hazards of CT radiation, it does not provide real-time images during the puncture procedure, thus requiring medical personnel to repeatedly probe and exit the operating room for positioning. Therefore, the positioning accuracy of the puncture needle is very important, and the accurate positioning not only can improve the operation success rate, but also can prevent the excessive ray exposure of patients and medical staff. The positioning of the puncture needle at present is usually carried out on the body surface by using an iron grid parallel to the long axis of the body and intercostal gaps, only the body surface puncture point can be determined, although a CT image provides a needle inserting angle, the needle inserting angle of the puncture needle in the actual puncture operation process mainly depends on the subjective feeling of medical staff, so that the target position can be reached only by repeated puncture probing and repeated CT positioning, the puncture success rate is greatly reduced, the unnecessary injury of a patient is increased, and the unnecessary ray exposure of the patient and the medical staff is increased.
Through the above analysis, the problems and defects of the prior art are as follows:
under the condition of the prior art, the positioning of the puncture needle guided by the CT is usually carried out on the body surface by using an iron grid parallel to the long axis of the body and intercostal gaps, only the body surface puncture point can be determined, the puncture needle angle in the puncture process cannot be fixed, the needle inserting angle mainly depends on the subjective feeling of medical staff, so that the target position can be reached only by repeatedly puncturing and probing and repeated CT positioning, the puncture success rate is greatly reduced, the unnecessary injury of a patient is increased, and the unnecessary ray exposure of the patient and the medical staff is increased.
The difficulty in solving the above problems and defects is:
at present, the puncture needle is usually positioned on the body surface by iron grids parallel to the long axis of the body and intercostal gaps, and only the puncture point on the body surface can be determined. Although the CT image provides the puncture angle, it is difficult to fix the puncture angle during the specific operation. Because the target position is often located in the body, and the needle insertion part of the human body is often a curved surface, the angle is difficult to measure by using a conventional protractor, and the measurement can only be based on the subjective feeling of an operator, which often causes multiple puncture tests and repeated positioning influenced by CT, thereby not only increasing the operation time, but also causing unnecessary ray exposure of a patient and medical staff.
The significance of solving the problems and the defects is as follows:
the operator can accurately puncture according to the angle provided by the CT in the puncture process, the puncture and CT positioning times are reduced, unnecessary damage to the patient and unnecessary ray exposure of the patient and medical staff are avoided, the operation time is reduced, and the use efficiency of medical resources is increased.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
In view of the problems of the prior art, the present invention provides a puncture auxiliary positioning device, which is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the puncturing auxiliary positioning device provided by the embodiment of the present invention has a transparent casing 1 filled with a colored liquid layer 4, and the colored liquid layer 4 occupies 1/2 of the volume of the transparent casing 1. Two injector fixing bayonets 2 are fixed at the bottom of the transparent shell 1, and two puncture needle fixing rings 3 are fixed at the two ends of the upper side of the transparent shell 1; the left side surface of the transparent shell 1 is carved with a needle head end scale mark 6, the right side surface of the transparent shell 1 is carved with a needle tail end scale mark 5, and the upper end of the transparent shell 1 is carved with an upper end scale mark 7.
The two ends of the colored liquid layer 4 are respectively flush with the 0-degree scale lines of the needle head end scale line 6 and the needle tail end scale line 5, and the positive and negative scale directions of the needle head end scale line 6 and the needle tail end scale line 5 are opposite. The middle of the upper end scale mark 7 is a +/-90-degree scale mark, and the scale numerical values of the upper end scale mark 7 gradually increase from left to right.
The embodiment of the utility model quantifies the needle insertion angle which is subjectively felt by medical staff, so that the needle insertion angle is more accurate and visual, and the deviation of the needle insertion angle is avoided. The whole transparent shell 1 in the embodiment of the utility model is a transparent cuboid plastic hollow shell, the front surface is a rectangle with a diagonal line forming an angle of 30 degrees with the bottom edge, and the transparent shell 1 contains a color liquid layer 4 with the volume occupying the cuboid volume 1/2. The two side surfaces and the top surface of the transparent shell 1 are respectively carved with a needle tail end scale mark 5, a needle head end scale mark 6 and an upper end scale mark 7. Regardless of the angle between the puncture needle and the horizontal plane, the liquid surface of the colored liquid layer 4 is always parallel to the horizontal plane due to gravity, and therefore the angle between the puncture needle and the horizontal plane is equal to the angle between the liquid surface of the colored liquid layer 4 and the bottom surface 8 or the liquid surface and the top surface 9.
In the embodiment of the utility model, the scale lines 5 at the tail end of the needle head, the scale lines 6 at the head end of the needle head and the scale lines 7 at the upper end on the transparent shell 1 mark the liquid level positions which respectively form an angle of-90 degrees to 90 degrees with the bottom surface 8 or the top surface 9 (the included angle between the puncture needle and the horizontal plane is set to be positive scale when the needle point faces downwards, and is negative when the needle point faces upwards) according to the geometrical knowledge.
The transparent casing 1 can be any transparent material including plastic and glass; the syringe fixing bayonet 2 and the puncture needle fixing ring 3 can be replaced by other fixing modes including fixing belts; the liquid contained in the auxiliary positioning module can be Newton, non-Newton liquid or other solid diffusible components; the shape of the positioning device is not limited to a cuboid with a diagonal surface forming 30 degrees with the bottom surface, and the positioning device can be a long hair body or other shape modules with any size, and the angle scales of the positioning device can be calculated by geometric knowledge.
In the puncture process, firstly, the body surface is determined and the puncture point is determined under the guidance of the CT, and simultaneously, the angle between the puncture path and the horizontal plane is measured on the CT image. Before the puncture operation, the transparent shell 1 is fixed on the injector through the injector fixing bayonet 2 (for example, the radio frequency ablation needle is fixed with the radio frequency ablation needle through the puncture needle fixing ring 3). When the puncture operation is carried out, the liquid level of the color liquid layer 4 is always kept parallel to the scale marks, so that errors caused by the inclination of the liquid level can be avoided. Then, according to the puncture point and the needle inserting angle measured by the CT image, the intersection line of the liquid level and the side surface or the bottom surface (top surface) of the transparent shell 1 is always kept on the corresponding scale for needle inserting, and the puncture angle can be fixed. Regardless of the angle of the puncture needle, the liquid surface of the colored liquid layer 4 is always parallel to the horizontal plane due to gravity, so the angle between the puncture needle and the horizontal plane is equal to the angle formed by the liquid surface of the colored liquid layer 4 and the transparent shell 1. The needle inserting angle of the puncture needle can be visualized, the puncture probing times and excessive CT ray exposure are reduced, and the puncture efficiency is improved.
