Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of thoracentesis, specifically to a positioning fence for thoracoscope puncture. BACKGROUND

[0002] Thoracentesis is a key technology in modern medical diagnosis and treatment, and plays an important role in the diagnosis and treatment of lung diseases. The traditional positioning method of thoracoscope puncture depends heavily on the experience of doctors, who position the human chest. However, there are differences in body size and height among different patients, such as the diversity of chest shape, lung position, and lesion position. The error of positioning only relying on surface markers may be large. For example, in the case of lung nodule puncture, it is difficult to find the nodule due to its small size and hidden location through traditional positioning methods. Meanwhile, the position of the lung and lesion may change due to patient's respiratory movement during CT irradiation guidance, making direct puncture without reference material prone to failure or multiple punctures, which increases the patient's pain and the risk of complications, and may delay diagnosis and treatment of the disease. In addition, when the patient has conditions such as pleural effusion and pleural adhesion, it will increase the difficulty of puncture on the surface of the anatomical structure, and cannot provide accurate and reliable positioning support for doctors. In view of the above problems, a precise, simple-to-operate, and complex positioning fence is developed, which has important clinical significance for the puncture positioning of thoracoscope.

DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.

[0029] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a positioning fence for thoracoscope puncture, including magic paste wool hook layer 1, the outer surface of one side of magic paste wool hook layer 1 is fixedly pasted with cloth adhesive layer 2, and the outer surface of cloth adhesive layer 2 is attached with the chest cavity skin outer surface of patient, the outer surface of one side of magic paste wool hook layer 1 is attached with magic paste felt layer 3, the outer surface of magic paste felt layer 3 is attached with the outer surface of magic paste wool hook layer 1, rubber sheet 6 is fixed with the outer surface of magic paste felt layer 3, and metal fence pole 8 is arranged between rubber sheet 6.

[0030] Before the thoracoscope puncture, the patient needs to be placed in the correct position, then use low-dose CT to guide and paste the electrode sheet, and fully expose the position of the 7-9 ribs of the patient's midaxillary line and posterior axillary line. Then the hook layer 1 of the magic tape is fixed and pasted on the outer surface of the skin of the patient's midaxillary line through the fabric adhesive layer 2, and the felt layer 3 of the magic tape is pasted and fixed with the hook layer 1 of the magic tape, so that the hook layer 1 and the felt layer 3 of the magic tape can be fixed along the curved surface of the patient's midaxillary line and posterior axillary line. Then the metal fence rod 8 can be inserted into the inside of the rubber sheet 6, so that the metal fence rod 8 can be located around the electrode sheet. Then air filtered by gauze is injected into the thoracic cavity through the drainage tube, and CT scanning is performed. By observing the position of the electrode sheet, the metal fence rod 8 and the artificial pneumothorax, the position of the surrounding skin adhesion, and the separation of the dirty layer and the wall layer of the pleura, it is observed whether subcutaneous pneumothorax and mediastinal pneumothorax occur. If the electrode sheet positioning is not good, the hook layer 1 and the felt layer 3 of the magic tape can be separated to facilitate the removal of the electrode sheet. Then the hook layer 1 and the felt layer 3 of the magic tape are reset, and then the position of the metal fence rod 8 and the pneumothorax is compared, and the CT infrared positioning is used to reposition and mark, which is convenient for removing the electrode sheet and facilitating separation and resetting. At the same time, according to the metal fence rod 8, the positioning can be assisted to improve the accuracy of the thoracoscope puncture.

[0031] The outer surface of the rubber sheet 6 is uniformly provided with the insertion hole 7, and the insertion hole 7 is penetrated by the metal fence rod 8.

[0032] The position of the metal fence rod 8 on the rubber sheet 6 can be adjusted at will through the insertion hole 7, so that the positioning and adjustment can be more convenient.

[0033] The outer surface of the two ends of the metal fence rod 8 is provided with the rough rod 9, and the outer surface of the rough rod 9 is matched with the outer surface of the insertion hole 7.

[0034] The design of the rough rod 9 can effectively increase the friction between the insertion hole 7, so that the metal fence rod 8 will not accidentally slip out of the insertion hole 7 during use, and the metal fence rod 8 will not move randomly, so that the metal fence rod 8 will not slip out or move during CT irradiation, improving the accuracy of positioning.

[0035] The outer surface of the end of the magic tape felt layer 3 away from the fabric adhesive layer 2 is sewn and fixed with the glass fiber cloth 4, and the outer surface of the glass fiber cloth 4 is sprayed with scale lines 5, and the side surface of the glass fiber cloth 4 is matched with the outer surface of the rubber sheet 6.

[0036] The scale line 5 printed on the glass fiber cloth 4 will not be affected by deformation caused by pulling due to the tensile deformation resistance of the glass fiber cloth 4 itself, and the distance between the metal fence rods 8 can be more intuitively observed through the scale line 5, and the lesions of the patient's intercostal space can be conveniently recorded.

[0037] The rubber sheet 6 is fixedly sewn with a pull joint 10 on one side of the outer surface, and the pull joint 10 is a belt-shaped body made of flexible material.

[0038] The pull joint 10 can be more easily separated from the magic tape felt layer 3 and the magic tape hook layer 1, and can be torn and pulled with the help of a place.

[0039] The high-friction surface 11 is fixedly sewn on the outer surface of the pull joint 10, and the high-friction surface 11 and the pull joint 10 are located on the outer side of the magic tape felt layer 3.

[0040] The high-friction surface 11 can increase the friction, so that when the magic tape felt layer 3 and the magic tape hook layer 1 are pulled apart, the hand will not slip due to the liquid and other substances.

[0041] The pull joint 10 is provided with a pull ring rope 12, and the outer surface of the pull ring rope 12 is attached to the inner surface of the pull joint 10.

[0042] The pull ring rope 12 can hang and store the magic tape felt layer 3 and the rubber sheet 6, and the fingers can pass through the pull ring rope 12 to separate the magic tape hook layer 1 and the magic tape felt layer 3.

[0043] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
