Description

Technical Field

[0001] The present invention belongs to the technical field of prostate puncture surgery, and in particular relates to a locatable prostate biopsy puncture needle based on NFC technology. Background Art

[0002] At present, the mainstream prostate biopsy puncture surgery is that the patient first undergoes an MRI scan, and the preoperative MRI is used to plan the target of the biopsy puncture. During the operation, the doctor holds an ultrasound probe in his hand and performs an ultrasound scan of the prostate through the rectum (the rectum is closest to the prostate). The doctor compares and checks the data images of the preoperative MRI scan with the real-time ultrasound scan data images to determine the location of the lesion target and complete the prostate biopsy puncture surgery.

[0003] Doctors determine the location of target lesions by comparing and checking the data images of magnetic resonance scanning and real-time ultrasound scanning. Doctors need to judge the relative position of the prostate and target lesions in three dimensions based on their own experience, which is not intuitive enough. This may lead to a large error between the actual target lesion location and the target lesion location judged by the doctor, thus failing to achieve the purpose of biopsy surgery and having certain limitations. Summary of the invention

[0004] The purpose of the present invention is to provide a locatable prostate biopsy puncture needle based on NFC technology to solve the problem mentioned in the above background technology that most of the existing prostate biopsy puncture operations are performed by doctors to judge the relative positions of the prostate and the lesion target in three-dimensional space, which is not intuitive enough. This may lead to a large error between the actual lesion target position and the lesion target position judged by the doctor, thus failing to achieve the purpose of the biopsy operation and having certain limitations.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a locatable prostate biopsy puncture needle based on NFC technology, comprising a biopsy puncture needle body, a biopsy puncture needle sensor mounting seat is sleeved on the outer surface of one end of the biopsy puncture needle body, the biopsy puncture needle sensor mounting seat comprises a biopsy puncture needle sensor fixing frame and a biopsy puncture needle sensor fixing seat, the biopsy puncture needle sensor fixing frame and the biopsy puncture needle sensor fixing seat are fixedly sleeved on the outer surface of the biopsy puncture needle body by screws, and the upper end of the biopsy puncture needle sensor fixing seat is threadedly fixedly connected with a biopsy puncture needle positioning sensor.

[0006] Preferably, the biopsy puncture needle positioning sensor includes a biopsy puncture needle sensor lower cover plate, a biopsy puncture needle sensor upper cover plate and a magnetic locator sensor, a cylindrical gap is provided between the biopsy puncture needle sensor lower cover plate and the biopsy puncture needle sensor upper cover plate, and a magnetic locator sensor is fixedly installed in the gap between the biopsy puncture needle sensor lower cover plate and the biopsy puncture needle sensor upper cover plate.

[0007] Preferably, a fixed sleeve is fixedly connected to the end of the outer surface of the needle of the biopsy puncture needle body, and a protective sleeve is fixedly sleeved on one end of the fixed sleeve.

[0008] Preferably, an NFC module is disposed inside the biopsy puncture needle holder to store the transformation relationship between the magnetic locator sensor and the biopsy puncture needle tip. The transformation relationship can be used to track the magnetic locator sensor by the magnetic locator to directly locate the position of the biopsy puncture needle tip.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The biopsy puncture needle positioning sensor provided in the present invention can track and locate the puncture position of the biopsy puncture needle body. In combination with the three-dimensional model of the data image of the patient's preoperative magnetic resonance scan, the real organ model can be simulated by computer, thereby intuitively displaying the puncture position of the biopsy puncture needle body in three dimensions, making the doctor's observation more intuitive, reducing surgical errors, and making the surgery safer.

[0011] 2. The protective sleeve provided in the present invention can, on the one hand, provide a sealing and dustproof protection for the needle, and on the other hand, when the needle is discarded, the needle can be protected by a sleeve to prevent scavengers and other garbage station workers from accidentally hitting and stabbing the needle, thus playing a certain role in preventing stabbing injuries.

[0012] 3. The present invention stores the transformation relationship between the magnetic locator sensor and the biopsy needle tip through the NFC module. On the one hand, the transformation relationship can be directly used to locate the position of the biopsy needle tip. On the other hand, there is no need to recalibrate the biopsy needle tip and the magnetic locator sensor before the operation, which greatly saves the operation time.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-4 The present invention provides a technical solution: a locatable prostate biopsy puncture needle, comprising a biopsy puncture needle body 1, a biopsy puncture needle sensor mounting seat 8 is sleeved on the outer surface of one end of the biopsy puncture needle body 1, the biopsy puncture needle sensor mounting seat 8 comprises a biopsy puncture needle sensor fixing frame 2 and a biopsy puncture needle sensor fixing seat 3, the biopsy puncture needle sensor fixing frame 2 and the biopsy puncture needle sensor fixing seat 3 are fixedly sleeved on the outer surface of the biopsy puncture needle body 1 by screws, the upper end of the biopsy puncture needle sensor fixing seat 3 is threadedly fixedly connected with a biopsy puncture needle positioning sensor 7, an NFC module 11 is placed inside the biopsy puncture needle sensor fixing seat 3, and the transformation relationship between the magnetic locator sensor 6 and the biopsy puncture needle needle head is stored in the NFC module 11.

[0020] In this embodiment, the biopsy puncture needle sensor fixing frame 2 and the biopsy puncture needle sensor fixing seat 3 are screwed and sleeved on the outer surface of the biopsy puncture needle body 1, and then the biopsy puncture needle positioning sensor 7 is screwed to the upper end of the boss of the biopsy puncture needle sensor fixing seat 3, which can play a certain role in thread fixing the biopsy puncture needle positioning sensor 7. At the same time, the thread installation can be repeatedly installed and disassembled on the biopsy puncture needle sensor mounting seat without changing the relative position. Before puncture, the doctor obtains the transformation relationship between the magnetic locator sensor stored in the NFC module and the biopsy puncture needle needle through the NFC reading device. By means of the biopsy puncture needle positioning sensor 7, the doctor can see the biopsy puncture needle body 1 and the patient's preoperative MRI scan data images on the computer when performing puncture. The patient's preoperative MRI scan data has been converted into a three-dimensional model, which is a real organ model of the patient. The position of the biopsy puncture needle body 1 can be located by means of the biopsy puncture needle positioning sensor 7, so the biopsy puncture needle has also been converted into a three-dimensional model through computational simulation. What is displayed on the interface is a three-dimensional model, and the three-dimensional model displayed on the interface will be tracked in real time according to the doctor's real-time operation, so the doctor's observation is more intuitive.

[0021] Specifically, the biopsy puncture needle positioning sensor 7 includes a biopsy puncture needle sensor lower cover plate 4, a biopsy puncture needle sensor upper cover plate 5 and a magnetic locator sensor 6. A cylindrical gap is provided between the biopsy puncture needle sensor lower cover plate 4 and the biopsy puncture needle sensor upper cover plate 5. The magnetic locator sensor 6 is fixedly installed in the gap between the biopsy puncture needle sensor lower cover plate 4 and the biopsy puncture needle sensor upper cover plate 5.

[0022] In this embodiment, the magnetic locator sensor 6 is set to be tracked by the magnetic field generator, and then by reading the transformation relationship between the magnetic locator sensor 6 and the biopsy needle tip stored in the NFC module 11, the spatial position of the biopsy needle can be tracked.

[0023] Specifically, the end of the outer surface of the needle of the biopsy puncture needle body 1 is fixedly connected with a fixed sleeve 9, and one end of the fixed sleeve 9 is fixedly sleeved with a protective sleeve 10.

[0024] In this embodiment, the protective sleeve 10 can, on the one hand, provide a sealing and dust-proof protection for the needle, and on the other hand, when the needle is discarded, the needle can be protected by the sleeve to prevent scavengers and other garbage station workers from accidentally touching and stabbing the needle, thereby playing a certain role in preventing stabbing injuries.
