Description

Device for positioning lung tumor and long-term tissue retention and guidance

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a device for positioning lung tumor and guiding long-term tissue retention.

Background

The lung cancer is one of the highest malignant tumors of morbidity and mortality in China, and with the popularization of low-dose helical CT (LDCT) lung cancer screening, the sensitivity of early lung cancer diagnosis is improved, more and more isolated small lung tumors are discovered, and because the tumors have certain malignant probability, the diagnosis and treatment of the tumors are the key points of attention of clinicians.

Television thoracoscopic surgery (VATS) provides a minimally invasive way for diagnosing and treating lung tumors, but the visual field and the operation space of an endoscopic operator are limited, so that the tumor position is often difficult to rapidly determine in the operation, and researches show that the probability of thoracotomy is required to be turned off to 46 percent because the tumor cannot be clearly positioned in the operation, thereby bringing adverse effects to the actual use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a device for positioning lung tumor and guiding long-term retention of tissue, which can quickly position the position of lung tumor and is convenient for biopsy and drug delivery treatment.

In order to achieve the purpose, the utility model adopts the technical scheme that:

due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

the lung tumor positioning and tissue long-term indwelling guiding device has the advantages of simple overall structure and convenience in operation, an expandable puncture piece is used for puncturing the tumor, then the tumor of the lung is positioned by using the inflatable balloon, the subsequent operation is facilitated, biopsy can be performed through the hollow part of the puncture piece, meanwhile, a drainage tube can be connected to the puncture piece, and then therapeutic drugs can be conveniently guided into the human body, so that a safer, more accurate and more convenient positioning device can be provided for patients and clinicians, and the device has better practicability.

Drawings

The technical scheme of the utility model is further explained by combining the accompanying drawings as follows:

FIG. 1 is a schematic structural diagram of a first embodiment of the present invention;

FIG. 2 is a schematic structural diagram of a second embodiment of the present invention;

wherein: puncture piece 1, sacculus 2, connecting piece 3, guide 4, external hose 5, negative pressure ball 6, drainage tube 7.

Detailed Description

The utility model is described in further detail below with reference to the figures and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not to be construed as limiting the utility model.

Example one

Referring to fig. 1, a device for positioning a lung tumor and guiding long-term tissue retention according to an embodiment of the present invention includes a puncture member 1, a balloon 2, a communication member 3, and a guide member 4; specifically, the puncture element 1 is in the shape of a long rod, and the interior of the puncture element 1 is hollow; in this embodiment, the puncturing member 1 is an expandable silicone tube, so that it not only has an expansion function, but also can satisfy the requirements of different needle core sizes, and simultaneously can ensure no damage to human body when in use.

Further, since the puncture device 1 needs to puncture the lung, the bottom of the puncture device 1 is generally harder than the middle-upper part, and the puncture is facilitated.

Wherein, a communicating piece 3 is communicated with the top of the puncture piece 1, the communicating piece 3 is a two-way hose in the embodiment, a negative pressure ball 6 and a drainage tube 7 are respectively arranged on the two-way hose, and a saccule 2 is arranged at the bottom of the puncture piece 1; the negative pressure ball 6 enlarges the saccule 2 after passing through the communicating piece 3 and the puncture piece 1, thereby realizing the positioning effect on the tumor through the enlarged saccule; in addition, the drainage tube 5 can be put under the skin, so that after the puncture piece 1 forms a sinus in a human body, some therapeutic medicines can be sent into the human body through the drainage tube 5 and the hollow of the puncture piece, and the operation is convenient and simple.

The guide part 4 is a metal part, so that the hardness is high, the guide part 4 penetrates through the external hose 7 to be arranged in the hollow of the puncture part 1, and when the puncture part 1 punctures the lung, the puncture part can conveniently puncture the lung through the guide of the guide part 4.

During actual work, firstly a negative pressure tunnel located in the lung is established, the guide piece 4 is placed in the hollow of the puncture piece 1, then the puncture piece 1 and the guide piece 4 are punctured towards the lung, and then the balloon 2 is enlarged by the negative pressure ball 6, so that the tumor is positioned by the balloon 2, and the operation is convenient.

Wherein, because puncture piece 1 is the expandable silicone tube, can satisfy the guide of different diameters size like this to match different nook closing member demands, application scope is wide.

And if the above state is maintained for 6-7 weeks, a sinus can be formed in the human body, thereby facilitating the operation of the subsequent operation; after the guide piece is subsequently taken out, the corresponding lesion part of the lung can be biopsied through the hollow part of the puncture piece, so that the subsequent operation is facilitated.

Example two

Referring to fig. 2, the difference between the present embodiment and the first embodiment is: the communicating piece 3 in this embodiment is a three-way hose, and the three-way hose is further communicated with an external hose 5, and the external hose 5 can facilitate the external transmission of various therapeutic drugs to the body of a patient.

The device for positioning the lung tumor and guiding the tissue to be kept in place for a long time has a simple integral structure and is convenient to operate, an expandable puncture piece is utilized to puncture the tumor, then the tumor of the lung is positioned by utilizing the inflatable saccule, the subsequent operation is convenient, the biopsy can be carried out through the hollow of the puncture piece, meanwhile, the treatment medicine can be conveniently guided into the human body after the puncture piece is connected with a drainage tube, a safer, more accurate and more convenient positioning device can be provided for patients and clinicians, and the device has better practicability.

The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
