[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0030] See also Figures 1 to 9 As shown, the utility model's intelligent locator and its auxiliary puncture surgical system require the cooperation of the puncture needle 4, the positioning sticker, the external imaging device and the intelligent locator, and the intelligent locator is connected to the external imaging device by signal. When performing the puncture surgery, the puncture needle 4 is first located by the positioning sticker to determine the needle insertion point, and then the intelligent locator is used to feedback the puncture angle of the puncture needle 4, so as to perform accurate puncture.

[0031] See also Figure 6-7 As shown, when positioning by positioning stickers, we can choose one-dimensional positioning stickers 5 or two-dimensional positioning stickers 6 to equip different imaging devices to determine the needle entry point. The one-dimensional positioning sticker 5 develops a grid strip on the image, such as Figure 6 The black vertical lines on the image can be displayed on the image. The two-dimensional positioning sticker 6 develops a grid on the image, such as Figure 7As shown, the two-dimensional positioning sticker 6 can be developed in both the X direction and the Y direction, and metal letters are marked on the side. The letters ABCD can all be developed on the image, which helps the doctor locate the needle insertion point more quickly.

[0032] External imaging equipment includes any one of spiral CT, mobile CBCT, and three-dimensional C-arm, which is used to obtain the patient's imaging data and provide accurate positioning information for puncture surgery.

[0033] Specifically, when the external imaging device is a spiral CT, first, a one-dimensional positioning sticker 5 is pasted on the body surface of the lesion area, then a spiral CT scan is performed on the lesion area, the CT examination bed is adjusted to the corresponding position, the cross laser light is turned on, and the needle insertion point is marked in combination with the grid bars on the image and the positioning laser light.

[0034] When using spiral CT, a two-dimensional positioning sticker 6 can also be pasted on the lesion area, and there is no need to use a cross laser light and a CT examination bed. The needle insertion point can be directly marked according to the grid on the image, which is faster and more convenient.

[0035] When the external imaging device is a mobile CBCT / three-dimensional C-arm, first, a two-dimensional positioning sticker 6 is pasted on the body surface of the lesion area, and the two-dimensional positioning sticker 6 develops a grid under CT. Then, a CBCT scan is performed on the lesion area, and the needle insertion point is marked according to the grid on the image.

[0036] Once the positioning sticker determines the needle insertion point, the doctor uses the smart locator to accurately navigate the puncture angle and position.

[0037] Example 1

[0038] See also Figure 1-2 As shown, a smart locator according to a preferred embodiment of the present invention is applied to puncture surgery. The smart locator is handheld and includes a puncture part 1 and an integrated part 2, and the two are fixedly connected.

[0039] The puncture part 1 comprises a connection end 11 , a puncture end 12 and a puncture channel 13 , wherein the connection end 11 is close to the integrated part 2 , the puncture end 12 is far away from the integrated part 2 , and the puncture channel 13 runs through the puncture end 12 and the connection end 11 .

[0040] The position of the puncture part 1 can be set at different positions of the intelligent locator according to the surgical requirements, which is very flexible. In this embodiment, the puncture part 1 is set at the edge of the integrated part 2. Figure 3-4 As shown, the integrated part 2 can also be arranged around the puncture part 1.

[0041] In addition, the smart locator also includes a hand-held portion 3 extending outward from the periphery of the puncture portion 1, which is convenient for the doctor to hold and operate.

[0042] The handheld portion 3 and the integrated portion 2 are respectively located on opposite sides of the puncture portion 1, so that the doctor can control the puncture angle more stably during operation.

[0043] The puncture channel 13 is configured to allow the puncture needle 4 to pass through, and the puncture end 12 is configured to contact the skin so that the puncture needle 4 enters the skin through the puncture end 12. During puncture, the doctor inserts the puncture needle 4 from the opening of the puncture channel 13 at the connecting end 11, and the puncture needle 4 passes through the puncture channel 13 and exits from the opening at the puncture end 12, and enters the human body at the same time.

[0044] The diameter of the puncture channel 13 matches the diameter of the puncture needle 4 to ensure that the puncture needle 4 can pass through the puncture channel 13 smoothly. The puncture channel 13 only accommodates one puncture needle 4 to ensure that the puncture needle 4 will not move arbitrarily in the puncture channel 13. When the position of the smart locator remains unchanged, puncture can only be performed from one angle, thereby enhancing the stability and accuracy of the puncture process and avoiding other unnecessary interference.

[0045] The integrated part 2 integrates a power supply module 21 , an angle sensor 22 and a wireless transmission module 23 . The power supply module 21 is electrically connected to the wireless transmission module 23 and the angle sensor 22 .

[0046] The angle sensor 22 is configured to read the inclination angle of the puncture channel 13 to determine the puncture angle information of the puncture needle 4. The wireless transmission module 23 is connected to the angle sensor 22 signal and configured to transmit the puncture angle information to an external imaging device.

[0047] Preferably, the power supply module 21 may be a rechargeable battery having a long battery life and a fast charging function to meet the needs of long-term surgery.

[0048] Furthermore, the smart locator can also be equipped with a display screen to display puncture angle information and other relevant data in real time, making it easier for doctors to observe and operate.

[0049] Preferably, the intelligent positioner of the utility model has waterproof and antibacterial functions to ensure safety and hygiene during surgery.

[0050] The puncture needle 4 and the smart locator of this embodiment are separately arranged. In the case of the separate arrangement, the puncture needle 4 can be displaced relative to the puncture channel 13 of the smart locator, so that the doctor can flexibly adjust the position and angle of the puncture needle 4 during the operation. After the puncture is completed, the doctor can easily remove the smart locator without interfering with the use of the puncture needle 4 or other surgical tools.

[0051] Example 2

[0052] See also Figure 5As shown, the smart locator in this embodiment is of a clamping type. The smart locator is not provided with a puncture channel 13, and directly clamps the handheld end of the puncture needle 4 through the clamping part 24 to perform puncture in sequence.

[0053] The integrated part 2 is fixedly connected to the clamping part 24. When the doctor performs puncture, the angle sensor 22 on the integrated part 2 reads the tilt angle of the puncture needle 4, and the wireless transmission module 23 is connected to the angle sensor 22 signal to transmit the puncture information read by the angle sensor 22 to the external device.

[0054] The puncture needle 4 and the smart locator of this embodiment are also separately arranged. In the case of the separate arrangement, after the puncture needle 4 punctures the human body, the doctor releases the clamping part 24 of the smart locator to separate the puncture needle 4 from the smart locator.

[0055] Example 3

[0056] See also Figure 6 As shown, the smart locator in this embodiment is embedded, and the power supply module 21, the angle sensor 22 and the wireless transmission module 23 are directly integrated on the puncture needle 4.

[0057] The puncture needle 4 of this embodiment is integrated with the intelligent locator, and the intelligent locator provides real-time feedback of the current puncture angle, which can reduce the number of surgical steps and improve surgical efficiency. After the puncture is completed, the intelligent locator and the puncture needle 4 are withdrawn together.

[0058] In the present invention, the entire puncture process is divided into two steps. The first is to locate the needle entry point using a positioning sticker, and the second is to simulate the puncture path using an intelligent locator.

[0059] Specifically, the required software is opened on the external imaging device, and the doctor selects the needle entry point on the image after reading the film. The needle entry point is connected to the center of the tumor / lesion. After the needle entry point is determined, the optimal puncture path is displayed on the image. This optimal puncture path is the path prepared for puncture.

[0060] Furthermore, the external imaging device receives the angle information wirelessly transmitted by the intelligent locator through a wireless transmitter. After the intelligent locator is connected to the external imaging device signal, the current angle of the puncture needle 4 can be simulated and displayed in real time on the image of the external imaging device software, and the puncture path simulated according to the current puncture angle can be displayed on both the two-dimensional tomographic image and the three-dimensional rendering image.

[0061] In summary, the intelligent locator of the utility model and the auxiliary puncture surgery system matched therewith can accurately measure and feedback the puncture angle information, and improve the accuracy and safety of the puncture surgery. At the same time, the system also has the advantages of simple structure and convenient operation, and can be widely used in clinical practice to bring better treatment effects and quality of life to patients.

[0062] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
