Fig. 7 is a schematic view showing a state of use of the spinal puncture positioning assistance device according to the first embodiment of the present invention.
As shown in fig. 7, the first puncture needle 200 is inserted into the first channel 21, and the second puncture needle is inserted into the second channel 22. The lower end surface of the positioning table 10 is in close contact with the skin of the patient, and the distance x between the first channel 21 and the second channel 22 is set on the lower end surface of the positioning table 10. As shown in table 1, 14 distances x between 14 second channels 22 and 14 first channels 21 are shown in table 1, and are all in mm. For example: the value 1.3 in the third row and the second column in table 1 represents: the predetermined angle α formed by the second channel 22 and the first channel 21 is 2 °, and the predetermined distance between the second channel 22 and the first channel 21 on the upper end surface of the positioning table 10 is 2mm, and the predetermined distance x between the second channel 22 and the first channel 21 on the lower end surface of the positioning table 10 is 1.3mm.
TABLE 1 values of distance x
The general spinal puncture needle needs to be inserted into the subcutaneous depth of a patient to be 10 cm-15 cm. In this embodiment, the distance y between the subcutaneous two ends of the first puncture needle 200 and the second puncture needle 300 is calculated by taking 13cm as an example. As shown in table 2, table 2 shows the possible 14 distances y between the distal end of the second puncture needle 300 and the distal end of the first puncture needle 200, which are all in mm. For example: the value 2.89 in the third row and second column in table 2 represents: the predetermined angle α formed by the second channel 22 into which the second puncture needle 300 is inserted and the first channel 21 is 2 ° and the predetermined distance between the second channel 22 and the first channel 21 on the upper end surface of the positioning table 10 is 2mm, and the distance y between the second puncture needle 300 and the two subcutaneous ends of the first puncture needle 200 is 2.89mm.
Table 2 values of distance Y
As can be seen from the data in Table 1, the distance between the first puncture needle 200 and the second puncture needle 300 on the skin surface is at most 4.24mm, i.e., the distance between the two wounds is not more than 5mm, the distance is very close, and the range is within the anesthesia range of the local anesthetic.
From the data in Table 2, it can be seen that the maximum value of the distance y between the distal end of the first puncture needle 200 and the distal end of the second puncture needle 300 is 20.69mm subcutaneously, i.e., the fine adjustment positioning range of the spinal puncture positioning aid 100 covers a circle with a radius of 20.69 mm. Furthermore, as can be seen from Table 2, there are 14 distances available, so that the fine-tuning positioning of the operator can be made very accurate.

Effects and effects of the examples
The spinal puncture positioning assisting device according to the present embodiment includes the positioning table and the channel portion including the first channel and the second channel, so that when the first needle of the operator is shifted from the target position of the patient, the spinal puncture positioning assisting device can be sleeved on the first needle, so that the first puncture needle passes through the first channel, and then the second puncture needle is inserted into the patient by selecting an appropriate second channel, and since the extending direction of each second channel and the predetermined distance from the first channel are determined, the relative position of the second needle inserted into the patient from the first needle can be known to achieve fine adjustment of the positioning. In this way, the operator can position the needle at the target point through at most two contact pins, thereby shortening the operation time and reducing the pain of the patient.
Further, the positioning table is divided into two detachable parts, which can be connected by a snap-fit connection or by a hinge connection. Before inserting the second puncture needle, the first puncture needle is inserted into the patient, so that the first puncture needle is directly sleeved on the first puncture needle, and the first channel can be detached in such a detachable manner, so that the spinal puncture positioning auxiliary device can be easily and quickly sleeved on the first puncture needle, the operation of a doctor is facilitated, the operation time is further saved, and the operation efficiency is improved.
Further, the positioning table is made of transparent materials, so that the trend of the first puncture needle and the trend of the second puncture needle can be visually seen.
Further, the side face of the positioning table is provided with a preset included angle corresponding to the indication, so that a doctor can conveniently and quickly find a second channel for operation.
