Technical Field

The invention relates to an ablation puncture auxiliary patch, in particular to an ablation puncture auxiliary patch guided by tomography equipment such as magnetic resonance equipment.

Background

When a substantial disease, particularly a tumor, occurs in an internal organ of a human body, a puncture is performed to clarify a pathology or directly perform an ablation treatment on a lesion. The current common method is to define the position and depth of the focus and the skin needle insertion point after scanning the human body by tomography devices such as magnetic resonance or CT, and carry out accurate puncture in the layer of the tomography where the focus is located. However, the conventional puncture positioning procedure can only determine the skin needle insertion point and depth, the specific needle insertion angle is mostly determined by visual inspection or experience of an operating physician, and the angle is often required to be adjusted for many times during the puncture process. In addition, the tail of the existing ablation puncture tool such as a radio frequency needle, a microwave needle or an argon-helium knife is provided with a small device, the small device has certain weight, when the puncture tool penetrates into skin or even muscle but does not penetrate into viscera, the direction needs to be confirmed by magnetic resonance or CT scanning, an operator can leave the side of a patient at the moment and release the puncture tool, the puncture tool is prone to being askew or changing the angle due to the weight of the tail part, particularly when the needle is inserted in a direction which is not perpendicular to the ground, the CT bed can aggravate the situation when the patient moves into a scanning area, the change of the angle direction of the puncture needle and the change of the needle insertion time are large during scanning, and the judgment and adjustment of the doctor are difficult. Some conventional auxiliary puncture devices are often too complex and bulky, have complex mechanical structures and high cost, and at the moment, a disposable fixing device which is simple and stable and can move along with a patient is needed, so that the ablation needle can be helped to select the optimal needle inserting angle, and the stable direction of the ablation needle which does not enter the parenchymal viscera in the deep position can be helped.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide an ablation puncture auxiliary device which is simple in structure, low in cost, stable in fixation, convenient to use and accurate in positioning.

In order to solve the technical problem, the invention discloses an ablation puncture auxiliary patch which is characterized in that: including the paster body, the paster body is by the slice component that soft material made, the inside one deck development line layer that is equipped with at least of paster body, the development line layer comprises many equidistance and mutual parallel arrangement's thin pore, constitutes the identity layer many thin pore of development line layer are in on the coplanar, the development line layer is parallel with paster body upper and lower surface, paster body lower surface is equipped with one deck non-setting adhesive tie coat.

As a further arrangement of the invention, hemostatic drugs are added into the self-adhesive bonding layer 3 of the patch body.

As a further arrangement of the invention, an upper developing line layer and a lower developing line layer are arranged in the patch body, and the projections of the thin pore passages in the two developing line layers are arranged in parallel.

As a further arrangement of the invention, the patch body is made of a transparent rubber or silicone material.

As a still further arrangement of the invention, the patch body incorporates an enhanced contrast agent, the enhanced contrast agent being an iodine contrast agent and/or a gadolinium contrast agent.

Compared with the prior art, the ablation puncture auxiliary patch is adhered to the body surface of a patient through the adhesive sticker adhesive layer, the development line is displayed under the action of CT or magnetic resonance tomography equipment by utilizing the different density (different signals under magnetic resonance) of the thin pore passage in the development line layer and the patch body under CT, and the ablation needle passes through the positioning of the development line, determines the needle inserting angle and directly reaches the focus after passing through the patch body. The ablation puncture auxiliary patch is simple in structure and low in cost, the patch body replaces skin, subcutaneous fat and muscle tissues of a patient, the defects in thickness are overcome, the puncture needle is more stable in fixation, and the patch is convenient to use and accurate in positioning.

The technical scheme of the invention is further specifically described below by combining the drawings and the embodiment.

FIG. 1 is a schematic perspective view of an embodiment of the present invention.

Detailed Description

As shown in fig. 1, the ablation puncture auxiliary patch of the present invention includes a patch body 1, wherein the patch body 1 is made of a sheet-shaped member made of a soft material, and is made of a rubber or silicone material, and the shape is preferably rectangular. The rubber or silica gel material is preferably a transparent hard medical silica gel material with a certain thickness, the transparent material is selected so that an operator can directly see a lower layer developing line clinging to the skin of a human body by naked eyes to help determine a puncture needle inlet point, the hardness of the silica gel material is higher than or equal to that of human muscles and lower than that of human cartilage, the puncture needle can be smoothly punctured, a stable supporting effect can be achieved on the puncture needle after puncturing, the puncture needle cannot be askew when the operator puts the hand on the support of the silica gel material, and the thickness is preferably 1.5-2.5 cm. The inside one deck development line layer that is equipped with at least of paster body 1, the development line layer comprises many equidistance and mutual parallel arrangement's thin pore 2, and the interval is less, is favorable to accurate positioning more, but also should not be too close, increases the preparation degree of difficulty. A plurality of thin pore channels 2 forming the same layer are positioned on the same plane, the developing layer is parallel to the upper surface and the lower surface of the paster body 1, and the lower surface of the paster body 1 is provided with a layer of adhesive bonding layer 3.

In order to accelerate wound healing, common wound hemostatic medicines such as Yunnan white powder are preferably added into the adhesive sticker bonding layer 3 of the patch body 1, and the patch is still attached to the skin of a patient after puncture, directly replaces the effect of gauze or wound attachment on postoperative wound dressing, reduces operation steps, is safer and is convenient for the patient and doctors.

In order to further increase the positioning accuracy, an upper developing line layer and a lower developing line layer are preferably arranged inside the patch body 1, and the projections of the thin pore channels 2 in the two developing line layers are arranged in parallel. Through the help of the upper and lower two-layer development line, can confirm puncture needle insertion point and angle more accurately and accomplish the puncture, the work load of the adjustment puncture angle that significantly reduces.

In order to be able to more clearly distinguish the air-containing pores 2 arranged in the silica gel under CT or MR scanning examination, it is preferred that the patch body 1 is doped with an enhancement contrast agent, such as an iodine contrast agent and/or a gadolinium contrast agent.

The ablation puncture auxiliary patch is stuck on the body surface of a puncture part of a patient through the adhesive sticker bonding layer 3 on the lower surface, and puncture is completed by determining a puncture needle inserting point and an angle through the help of upper and lower 2 layers of developing lines before a puncture tool enters the internal organs of a human body, so that the workload of adjusting the puncture angle is greatly reduced, even if the first positioning or direction has deviation due to various reasons, proper fine adjustment can be carried out (since silica gel still has certain flexibility, the slight adjustment direction is not a problem), and unnecessary damage and excessive CT radiation to the patient caused by repeatedly adjusting the puncture direction are reduced. Further experiments are needed to determine the most appropriate data, the thickness of the data cannot meet the requirements of the fixed support puncture needle, and the thickness of the data can increase the puncture difficulty; after the needle is removed, the puncture channel in the silica gel can be quickly closed due to the characteristics of the silica gel, so that the blood is prevented from overflowing through the puncture channel and is temporarily pressed by applying external force slightly.
