Description

Puncture needle
Technical Field
The invention relates to the field of medical equipment, in particular to a puncture needle.
Background
Breast cancer is one of the main malignant tumors that endanger the health of women, accounting for more than thirty percent of all malignant tumors of women, and is high in the first place. Currently, there are many methods for diagnosing breast cancer, including mammography, B-mode ultrasound, ductal endoscopy, etc., but the final diagnosis still depends on pathological diagnosis. Biopsy (abbreviated biopsy) is the most common means of obtaining a diagnosis of pre-operative pathology, and includes both needle biopsy and surgical biopsy methods. Compared with surgical biopsy, the puncture needle biopsy has less damage to normal tissues, no scar and relatively low cost. Most importantly, needle biopsies can eliminate unnecessary surgery for a portion of patients with benign lesions of the breast.
Although breast biopsy has many of the advantages described above, there is inevitably some risk due to the limited manner in which the biopsy needle surgery is operated. Specifically, tumors are classified into benign and malignant. If the biopsy-penetrated tissue is a benign lesion, its spreading and metastasis will not occur or be promoted in any way. If the tissue penetrated by biopsy is malignant focus, the needle head is necessarily stained with tumor cells when the biopsy is penetrated, so that the tumor cells stained on the needle head are necessarily brought into the needle passage in the tumor puncture needle withdrawal process, the tumor cell implantation occurs, and the needle passage transfer of breast tumor cells is initiated. Metastasis of tumor cells refers to the fact that malignant tumor cells are separated from the primary parts of malignant tumor cells and are dissociated into other organs through blood circulation and a lymphatic system to continue propagation and growth, so that tumors with the same properties are formed. This may affect the recurrence rate of breast cancer patients.

Detailed Description
In order to further describe the technical means and effects adopted for achieving the preset aim of the invention, the following detailed description refers to the specific implementation, structure, characteristics and effects according to the present invention with reference to the accompanying drawings and preferred embodiments.
As described in the background art, in the existing tumor puncture operation, the needle head of the puncture needle is stained with tumor cells, which can cause tumor needle tract metastasis.
Based on the above, the technical scheme of the invention provides a puncture needle. Referring to fig. 1, fig. 1 is a schematic view showing the structure of a puncture needle according to an embodiment of the present invention. The puncture needle comprises a needle body. The needle body comprises a power supply 30, a first component 10 and a second component 20.
The first component 10 is located at the distal end of the needle body, and the second component 20 is detachably connected to the first component 10. The first component 10 and the second component 20 are both cylinders and have the same diameter, so that the first component 10 and the second component 20 are smoothly butted into a whole. The distal end of the first assembly 10 is similar to the distal end of a conventional puncture needle and has a needle tip for performing a puncturing operation. The second component 20 may be made of a metallic material or a non-metallic material, which is not limited in the present invention.
The first component 10 includes an electrode (as shown in phantom in fig. 1), and the power supply portion 30 is electrically connected to the electrode to supply power to the electrode to change the temperature of the first component 10.
The power supply portion 30 includes a contact and a power supply line, and the power supply line of the power supply portion 30 passes through the second module. If the second component 20 is made of metal material, an insulating layer is disposed outside the power supply line to avoid electric leakage.
In one embodiment, the contacts are located at the ends of the power supply lines, which contact the electrodes of the first assembly 10 when the first assembly 10 and the second assembly 20 are connected, and which in turn are capable of supplying power to the electrodes in the first assembly 10. The first component 10 and the second component 20 may be screwed together, for example, as shown in fig. 1, the first component 10 has an external thread, the second component 20 has an internal thread, and a contact is located at the internal thread of the second component 20, and when the first component 10 and the second component 20 are screwed together, the contact is connected with the external thread (i.e., the electrode) of the first component 10.
In the embodiment shown in fig. 1, the power supply part comprises two contacts, one for providing a positive voltage and the other for providing a negative voltage. In other embodiments, the power supply part may also include three or more contacts, and the voltage output by each contact may be adjusted by a processing unit (described in detail below), so that, on one hand, if some contacts are damaged, the puncture needle of the present invention may provide a spare power supply part contact; on the other hand, different voltages can be provided for different contacts according to different tumors or different puncture positions so as to adapt to the illness state.
In another embodiment, the first component 10 and the second component 20 may be snapped together. For example, in fig. 1, the electrode connection part 11 of the first member 10 may be provided with an elastic protrusion (not shown), and the needle connection part 21 of the second member 20 may be provided with a groove (not shown) at a corresponding position. Before performing the puncture operation, the electrode connection portion 11 of the first module 10 is pushed into the needle connection portion 21 of the second module 20, and the first module 10 can be clamped with the second module 20. The second component 20 may also include an exit key that the physician or operator presses to disengage the first component 10 from the second component 20 after the lancing operation is completed or when a first component 10 of a different length needs to be replaced. Similar to the previous embodiments, the power supply section 30 includes a contact at the end of the power supply line, which contacts are in contact with the electrodes of the first assembly 10 when the first assembly 10 and the second assembly 20 are connected, and a power supply line, which contacts can then supply power to the electrodes in the first assembly 10.
In yet another embodiment, the first component 10 further comprises an insulating and thermally conductive layer 12, the insulating and thermally conductive layer 12 being applied to the electrode surface. The needle body 1 is provided with a catheter guide wire 40. When performing a penetration operation, the penetration needle of the present embodiment is inserted into the lesion tissue, and the catheter guidewire 40 grips or otherwise manipulates the lesion tissue via the needle body composed of the first assembly 10 and the second assembly. When the puncture operation is completed, the electrode of the first module 10 is supplied with power by the power supply part 30 to heat the first module, and tumor cells are destroyed. The insulating heat conducting layer 12 on the surface of the electrode can prevent the current in the electrode from burning the human body, and the use safety of the puncture needle is improved.
The first assembly 10 may have different axial lengths to accommodate different site puncture procedures. In one embodiment, the axial length of the first assembly 10 is 0.1cm to 15cm. For example, it may be 1cm, 2cm, 5cm, 8cm, 10cm, 15cm or the like. The first module 10 may have the same or different inner electrode lengths as the first module 10 having the same axial length. The electrode lengths in the first assembly 10 of different axial lengths may be the same or different.
Referring to fig. 2, fig. 2 is a first component of a lancet according to an embodiment of the present invention and a partial enlarged view thereof. The shape of the electrodes in the first assembly 10 may also be different depending on the heat generation requirements. For example, the electrode outer surface may be provided with a plurality of heat dissipation protrusions 13, and each heat dissipation protrusion 13 may be uniformly provided or may be provided in a locally concentrated manner.
Referring to fig. 3, fig. 3 is a schematic view showing the structure of a puncture needle according to another embodiment of the present invention. In this embodiment, the puncture needle further comprises at least one temperature sensor 50 for acquiring the temperature of the surface of the first component 10 and sending the temperature of the surface of the first component to a processing unit (not shown). As shown in fig. 2, a plurality of temperature sensors 50 may be distributed at the junction of the first component 10 and the second component 20, and the temperature sensors 50 may acquire the temperature of the first component 10 when the first component 10 and the second component 20 are screwed.
In other embodiments, a plurality of temperature sensors 50 may also be distributed in the first assembly 10 and provide communication line contacts where the second assembly 20 is connected to the first assembly 10. When the first and second components 10, 20 are tightened, each temperature sensor 50 may communicate with the processing unit via a communication line. In this embodiment, the processing unit may average the temperatures obtained by the respective temperature sensors, or weight-average the temperatures obtained by the respective temperature sensors, so as to obtain more accurate temperature data.
The processing unit may also be connected to the power supply 30 to control the power provided by the power supply 30 to the electrodes. As previously described, needles having first components of different lengths may be selected for different tumors. If the first component of the selected lancet is longer, the power supply may be required to provide greater power, and if the first component of the selected lancet is shorter, the power supply may be required to provide less power. In addition, since the materials of the electrodes in the first component of the lancet may be different, even if the lengths are the same for electrodes of different materials, it may be necessary for the power supply 30 to provide different power to heat to the same temperature. The processing unit may output different powers according to the difference of the accessed first components.
The processing unit may also be connected to a display unit for indicating the temperature of the surface of the first component. When the processing unit and the temperature sensor acquire the temperature of the surface of the first component, the temperature can be output to the display unit, for example, the temperature can be displayed to a doctor or an operator through an interface of an application program. The doctor or operator may also perform interactions with the various components of the lancet through the display unit. For example, when a sample of focal tissue is to be removed, a doctor or operator may click a control in the display unit to extend the catheter guidewire of the needle into the focal tissue and remove the sample; when the puncture needle is replaced by a different first component, a doctor or an operator can click a control in the display unit so that the output power of the power supply part corresponds to the currently installed first component; when the temperature of the surface of the first component of the puncture needle rises to a preset value, a doctor or an operator can manually cut off the power supply of the power supply part.
In summary, the puncture needle according to the present invention has a detachable first component at the end of the puncture needle, the first component includes an electrode, and the power supply portion of the puncture needle can supply power to the electrode to change the temperature of the first component. When the tumor puncture operation is performed, the power supply part can supply power to the first component, so that the temperature of the outer surface of the first component is increased, tumor cells are killed, and tumor cell needle transfer guided by the fact that the needle head is stained with the tumor cells in the needle withdrawing process of the puncture operation is avoided. Reduces the recurrence rate of cancer patients.
The present invention is not limited to the above embodiments, but is capable of modification and variation in all aspects, including those of ordinary skill in the art, without departing from the spirit and scope of the present invention.
