Description
Technical Field
The utility model relates to a medical instrument especially relates to a lung puncture locator.
Background
At present, the conventional method can not carry out pathological accurate diagnosis on lung diseases such as lung spherical focus, diffuse lesion and the like; the pathological dynamic observation of the treatment effect is carried out on patients with advanced tumor radiotherapy and chemotherapy; or the pathological changes in the lung or mediastinum, patients are unwilling or not suitable for operation treatment, a reasonable treatment scheme is selected for determining the pathological type, and the percutaneous lung puncture is mostly adopted to assist diagnosis or treatment clinically.
The doctor judges the needle insertion position according to experience when positioning the puncture point, most commonly, a bent clip is placed on the chest, then a photograph is taken to select the puncture point, the reliability of the method is poor, most of the methods still rely on the visual observation or experience of the doctor to insert the needle, and complications such as pneumothorax and the like are easily caused if the deviation is too large.
Therefore, the technicians in the field have researched and developed some related lung puncture positioning devices, and particularly, laser positioners are more common, for example, the chinese invention patent application (application number: 201410251061.5) discloses a laser positioning device for CT-guided puncture, which comprises a fixed frame, an omnidirectional rotating table, a fixed seat, a 360-degree omnidirectional linear laser positioner, an angle sensor and a display, wherein the fixed frame comprises a bracket and a sliding table, and the sliding table is fixedly connected with the bottom of the bracket; the omnibearing rotary table is fixedly connected with the sliding table; the fixed seat is provided with a fixed hole; the 360-degree omnibearing linear laser positioner is arranged in the fixed hole and is connected with the inner wall of the fixed hole through a bearing; the fixed seat is fixedly connected with the omnibearing rotary table; the angle sensor is fixedly connected with a 360-degree all-directional one-line laser positioner; the angle sensor is in transmission connection with the display.
However, since the laser locator needs to emit laser to form locating points on the skin of the human body, and the skin of the human body is irradiated by the laser for a long time during the puncturing process, the skin is composed of multiple tissue layers, each layer has different cells. When the laser irradiates the skin, if the energy (power) of the laser is too large, the laser can cause damage to the skin, and the laser dose and the skin damage degree are as follows: through a lot of practices, the larger the laser power density (or energy density) used when irradiating the skin is, the larger the damage to the skin is, and the two are in a positive correlation ratio. After the skin absorbs the laser energy exceeding the safety threshold, the skin of the irradiated part sequentially appears thermally induced erythema, blister, coagulation, thermally induced carbonization, boiling, combustion and thermally induced vaporization along with the increase of the dosage. The infrared laser mainly acts on the skin as heat burn, and when the ultraviolet laser irradiates the skin, the skin can be subjected to erythema and aging, and serious carcinogenesis can be caused when the skin is excessively irradiated. Although the light source emitted by the laser emitter is within a controlled safety range, the emitter can cause damage to the human body in case of a problem. In addition, the manufacturing cost of the laser positioner is also high, and the manufacturing process is complex, so that no related product is widely adopted in practice.
