Description

Visceral nodule puncture locator

technical field

The invention relates to a locator, in particular to a puncture locator for small visceral nodules, which belongs to the technical field of medical instruments.

Background technique

With the widespread use of advanced testing methods, many diseases can be detected and treated early, and some diseased nodules can be found by corresponding inspection methods at a relatively early stage, such as: lung, thyroid, kidney, liver, ovary, Small nodules in the prostate and muscles can be detected early by chest X-ray or CT, and small nodules in the thyroid, kidney, liver, ovary, prostate and muscles can be detected early by B-ultrasound. After the small nodules are detected, corresponding treatment should be done based on clinical experience. If the suspicion of malignancy is highly suspected, it should be removed as soon as possible; if the malignancy is not highly suspected, regular inspections can be performed before further treatment.

But the clinical dilemma is: although the small nodules were clearly found and positioned during the inspection, they were separated from the inspection tools and machines during the operation, and the positioning was extremely difficult, and it was difficult to achieve accurate positioning and resection. The small nodule is resected, but the surrounding normal tissue is also resected, which is far beyond the scope of normal treatment; in some cases, even the normal tissue adjacent to the small nodule is resected, but the small nodule is accidentally preserved. lead to surgical failure.

At present, puncture needles for small nodule localization have been invented clinically, but there are various defects. Some are made of metal, and covered with burrs not only bring discomfort and pain to patients, but also when the hard puncture needle encounters external force or even clothing friction, the end of the puncture needle will deviate, which will bring errors to the positioning results. The depth of the small nodules cannot be judged during resection; and although some puncture needles are smooth and soft, the patient suffers little pain, but they are easy to shift, and the surgical positioning effect is poor.

Some locators can only be found according to the hardness of the locators placed in the small nodules during the operation. Difficulty in finding them often occurs during the operation, which takes a long time, and even occurs due to the hard small nodules in the lung itself Positioning error.

At the same time, all puncture needles are bare needle shafts, and the needle body is not treated, which is very easy to cause risks due to puncture holes after puncture. Such as: bleeding at the puncture point after lung puncture, pneumothorax; blood flow after liver and kidney puncture, leading to emergency surgery.

There is a clinical need for an excellent small nodule puncture locator: accurate positioning, easy to quickly find during surgery, and quickly judge the resection range during resection; puncture is safe, and the puncture hole can be immediately closed after puncture to avoid various complications caused by it.

Generally, the positioning wire body 23 is made of materials that meet medical standards, and the length of the positioning wire body 23 is determined according to needs, as long as the positioning spring 20 is pushed into the small nodule, the tail end of the positioning wire body 23 is positioned at the small nodule. Outside the nodules, it is convenient to quickly locate the position of the small nodules. In addition, since the outer diameter of the puncturing operating rod 24 is greater than the outer diameter of the positioning wire body 23, when the puncturing operating rod 24 is used to puncture and the puncturing operating rod 24 is removed from the punctured area, in order to avoid pneumothorax and the like, the positioning A water-swellable layer is arranged on the thread body 23 . That is, when the positioning wire body 23 is in contact with the punctured area, liquid such as blood seeped from the puncture area can make the water-swellable layer on the surface of the positioning wire body 23 expand, and when the positioning wire body 23 expands, it can effectively block the puncture. The puncture hole produced when the operating rod 24 punctures. The positioning line body is made of medical materials, which can absorb water, and the volume will increase significantly after absorbing water. Specific materials such as: medical cotton, chitosan hemostatic sponge, silk fibroin, amniotic membrane, collagen, expanded polytetrafluoroethylene Ethylene, bacterial cellulose, water-absorbent resin, medical grade gelatin, etc.; the water-swellable layer will absorb water and swell after puncture, and can block the puncture hole after swelling, avoiding complications caused by puncture trauma, such as: when lung puncture To avoid pneumothorax and bleeding, etc., the specific type of the water-swellable layer can be selected and determined according to the needs, which are well known to those skilled in the art, and will not be repeated here.

When the positioning wire body 23 is set on the positioning spring 20, the positioning wire body 23 penetrates in the spring push tube 26 and passes out from the end of the spring push tube 26, that is, the positioning wire body 23 is in the spring push tube 26 and is positioned at the spring. Between the push tube 26 and the puncture operating rod 24. When the spring push tube 26 moves on the puncture operating rod 24 so that the positioning spring 20 enters the punctured nodule, part of the positioning wire body 23 in the elongated state will follow into the nodule, and the positioning wire body 23 will The tail end stays out of the small tubercle, so that unnecessary entanglement and the like will not occur.

In addition, the positioning wire body 23 is provided with several barbs for preventing the positioning wire body 23 from moving, and the barbs are distributed obliquely on the positioning wire body 23 . In the embodiment of the present invention, the inclination direction of the barb should ensure that it does not affect the head end part of the positioning wire body 23 to follow the positioning spring 20 into the small tubercle, and the tail end part outside the small tubercle will not be completely damaged due to movement. into the nodules; at the same time, the positioning wire 23 entering into the nodules will not exit from the nodules due to movement. During specific implementation, the barb is made of a soft material to avoid unnecessary damage.

The puncture operating rod 24 is provided with a push tube positioning mechanism for positioning the spring push tube 26, and the spring push tube 26 is located between the positioning spring 20 and the push tube positioning mechanism;
