Description

External serial number visible system of general percutaneous puncture needle

Technical Field

The invention relates to the technical field of medical instruments, in particular to a universal percutaneous puncture needle specific in-vitro numbering visual system.

Background

Malignant tumors are a serious threat to human health and life, and with the increasing development of interventional therapy and related materials, the development of minimally invasive techniques for local treatment of solid tumors is rapid, such as Percutaneous Radiofrequency ablation (RFA), Percutaneous Cryotherapy (PCT), or Argon-helium knife (Argon-helium target cryotherapy), Percutaneous Microwave Coagulation Therapy (PMCT), Laser-induced thermal ablation (LITT), Irreversible electroporation (IRE), or Nanoknife (Nanoknife), which has been developed vigorously. The treatment effect of the multiple percutaneous minimally invasive ablation technologies on small focuses of various solid tumors is generally positive, usually the destructive target of surgical excision can be achieved, but large masses above 5cm are often difficult to ablate completely, so that the current clinical strategy is to puncture local focuses through multiple needle combinations and perform treatment in a combined manner.

The necessary premise of multi-needle puncture treatment is that the scientific planning before the operation and the accurate positioning during the operation are performed, and for a large tumor mass of more than 5cm, even more than 10cm, the planning before the operation requires that the puncture during the operation is provided with a plurality of ablation needles according to the shape of the tumor, and the number of the needles is more than 10 in practice. The biggest difficulty for inexperienced doctors in such operation is not the positioning of the puncture point, but the needle needed to be adjusted is difficult to distinguish because the specifications of various puncture needles are consistent when the angle and the depth of the needle need to be adjusted in a narrow body surface area in the operation. Meanwhile, the needle shadows are easy to interfere with each other on the Computed Tomography (Computed Tomography) image (CT) image used for conventional monitoring, because the preoperative needle arrangement design is based on the growth status of solid tumors, the puncture needle is usually not inserted horizontally or vertically, and there may be needle shadows punctured from a plurality of other positions on the same layer on the CT. If the patient can not take one injection, the patient can be adjusted in the operation and can only count and analyze one by one according to the layer and the distance, thereby spending a great deal of energy, prolonging the operation time, causing the pain of the patient to increase and also causing the waste of medical resources.

Aiming at the clinical practical problem of adjustment in multi-needle operation, a 3D printing template is adopted by a student for accurate positioning, but the method is mainly used for Percutaneous penetrating radioactive particle implantation (Percutaneous implantation of brachythermy seeds), and other ablation methods are relatively rarely used; moreover, due to the problem of individual template charging, clinical popularization is difficult. In recent years, a new technology IRE is commonly called as a nano-knife, the tail of a matched puncture needle is numbered, the nano-knife is clear at a glance in vitro, but the nano-knife is not a metal mark, so that the nano-knife can not be distinguished under CT images, and the problem can not be avoided in the process of puncture adjustment by using multiple needles.

Chinese patent documents: CN201080067284.6, application date: 2010.09.29, the patent names: ultrasound visualization of percutaneous needles, intravascular catheters, and other interventional devices. An interventional medical device includes fluid channels for microbubbles that are imaged using ultrasound during use of the device. The fluid channel extends through the device, preferably to the distal tip of the device, so that diffuse reflections of ultrasound from the microbubbles can be received to image the location of the device. The fluid channel may be open, terminating at the tip of the device, or may be a closed path for a circulating microbubble fluid for imaging and/or cooling. This invention is only for visualization of ultrasound microwaves and is more complex to use with imaging labeling methods.

Looking up other related reports, a universal in-vitro numbering system which is simple and convenient and is suitable for various percutaneous puncture ablation puncture needles is still lacking at present. The system is convenient for accurately positioning the puncture needle and performing subsequent adjustment operation under the imaging, so as to furthest shorten the time required by accurate and in-place puncture, reduce the pain of a patient and shorten the radiation time when the system is used in a clinical interventional minimally invasive surgery, and improve the working efficiency and the safety and effectiveness of interventional therapy.
