Description

Novel fastening disc easy to puncture

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a novel fastening disk of easily puncturing.

Background

The percutaneous lung puncture biopsy and the lung tumor radio frequency ablation under the guidance of CT are the diagnosis and treatment technologies which are commonly used in clinic at present. Before operation, an operating range of the lung lesion to be operated is determined by scanning with image equipment such as CT (computed tomography) equipment, the optimal skin puncture point, the optimal needle insertion angle and the optimal needle insertion depth of the lesion are determined according to the position and the size of the lung lesion, and then the puncture operation is performed. The needle insertion condition can not be observed in real time under the conventional CT, the needle insertion depth and the needle insertion angle must be estimated after the skin needle insertion point is determined, the puncture needle is clamped by the lung tissue of the chest wall of a patient after the needle insertion, and the CT scanning is performed again to confirm whether the needle point reaches the ideal position of lesion or not, so that the puncture biopsy can be carried out.

The occurrence of operation complications is related to factors such as the proficiency of an operator, the adjustment times of repeatedly inserting and withdrawing the needle, the acute angle of the puncture needle and the pleural tangential line of a puncture point, the existence of pulmonary emphysema and pulmonary bullous of a patient and the like. In order to avoid complications such as pneumothorax and hemothorax caused by multiple times of puncture, a puncture needle is generally fixed on a chest wall tissue layer by puncture, and then the puncture direction angle and the puncture depth are continuously adjusted according to the relative position of the puncture needle and a focus in a lung in an image through repeated CT scanning for multiple times, so that the puncture needle can finally accurately reach the inside of the focus tissue. Partial thin and weak patients have difficulty in fixing the puncture needle on a thinner chest wall layer, the puncture needle is inserted to a sufficient depth to puncture a chest membrane layer to reach lung tissues, and in the subsequent process of adjusting the needle insertion angle, the occurrence rate of pneumothorax complications is greatly increased by repeatedly passing in and out the puncture needle, so that the success rate of puncture biopsy is reduced.

With the rapid advance of modern medical engineering technology, large medical equipment for lung scanning, such as CT, MR and the like, has great technical progress earlier, but the percutaneous lung puncture operation under CT guidance still adopts the traditional mode of free-hand operation at present. Because of lacking the assistance of fixed facility of puncture, many operation links can't accomplish ration accurate. Successful implementation of lung aspiration biopsy still depends on subjective judgment of an operator and skill level of the technique to a great extent, and is insufficient and cannot meet the requirement of rapid social development.

In view of the above, there is a need for a new fastening disc that is easy to puncture to overcome the deficiencies of the prior art.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, influence the puncture precision among the actual treatment, the utility model provides a novel fastening disc of easily puncturing, the modern design effectively improves the success rate of puncture operation, reduces the emergence probability of complication, and practicality is excellent, has solved prior art's defect.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

The utility model provides a novel fastening dish of easily puncturing, includes the sucking disc, the axle center department at sucking disc top is provided with the fastening dish of location pjncture needle, and the shape of fastening dish is cylindricly, and the sucking disc lies in same horizontal plane with the bottom plane of fastening dish, and hollow absorption chamber is seted up to the middle part of fastening dish, and the diameter in absorption chamber is greater than the wall thickness of fastening dish, and the puncture groove has been seted up to the top surface of fastening dish, and the diameter of fastening dish is half of sucking disc diameter, and the height of fastening dish is 3-5 mm.

The material that sucking disc and fastening dish adopted be silica gel, sucking disc and fastening dish adopt silica gel mould integrated into one piece.

furthermore, the sucker is in a spherical convex shape.

The fastening disc of the utility model is circular, and the wall thickness of the fastening disc is 3-8 mm.

Furthermore, the puncture groove is in a cross shape or a circular shape.

The diameter of the sucker of the utility model is 35-50 mm.

the utility model has the advantages that: this product novel in design, simple structure adopts soft material to make, can effectual fixed pjncture needle, does not rely on operator's subjective judgement and gimmick proficiency, improves the success rate of operation, reduces the incidence of sick disease, does benefit to patient's recovery, and the practicality is excellent, is a fine innovation scheme, has very much the marketing prospect.
