Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, specifically to a body surface locator for lung puncture. Background Technology

[0002] In recent years, with the improvement of people's living standards and the enhancement of self-care awareness, the number of people actively undergoing physical examinations has increased year by year, and the incidence of pulmonary space-occupying lesions has shown an upward trend and a younger age of onset. Pulmonary space-occupying lesions refer to lesions that appear as mass shadows in the lungs on CT and X-ray examinations, but whose nature needs to be clarified by other relevant examinations. Early and accurate diagnosis and standardized treatment are of great significance for improving patient prognosis. CT-guided percutaneous lung biopsy has been increasingly applied to the diagnosis of pulmonary space-occupying lesions. It uses a puncture needle to reach the lesion tissue through the skin and obtain tissue for pathological examination. It has the advantages of simple operation, few complications, and high accuracy. However, CT guidance alone can only show the approximate location, size, and presence of large blood vessels of the lesion, but it cannot pinpoint the exact location. Moreover, the boundary between the patient's body surface location and the relative location of the lung lesion is unclear, making it difficult to determine the needle insertion angle relative to the body surface and the location of the lesion. This often requires multiple needle insertions, greatly increasing the probability of post-puncture complications. In addition, the radiation exposure time is long, increasing the risk of radiation damage. Summary of the Invention

[0003] To address the problems existing in the background art, the present invention provides a body surface locator for lung puncture, which can help physicians correctly determine the positional relationship between the lesion and the body surface, find the accurate puncture angle and puncture position, and improve the puncture success rate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention provides a surface locator for lung puncture, comprising a locator body, a locating seat, a fixed angle plate, a rotating shaft, and an angle positioning component. The upper surface of the locator body is provided with multiple positioning meridians and multiple positioning parallels, which are arranged at equal intervals and intersecting horizontally and vertically. The locator body is connected to the locating seat on at least one side. A U-shaped mounting groove is formed on the outer side of the locating seat. The rotating shaft is connected to the end of the fixed angle plate and is located within the U-shaped mounting groove. Both ends of the rotating shaft are movably disposed within a rotating groove located on the inner sidewall of the U-shaped mounting groove. The rotating groove has a circular cross-section. An angle positioning component is provided between the end of the rotating shaft and the interior of the rotating groove, and the angle positioning component can limit and fix the rotation angle of the rotating shaft within the rotating groove.

[0006] A further improvement is that the angle positioning component includes a locking rod and an arc-shaped limiting groove. Multiple arc-shaped limiting grooves are symmetrically formed along the circumferential direction on the inner side of the rotating groove. Oppositely arranged grooves are formed on the outer sides of both ends of the rotating shaft. One end of the locking rod is movably installed in the groove, and an elastic element is provided between the end of the locking rod and the inside of the groove. The end of the locking rod away from the groove can be movably locked into the arc-shaped limiting groove. The end of the locking rod that mates with the arc-shaped limiting groove has a semi-circular structure. In use, an external force is applied to the fixed angle plate to rotate it. Under the action of the external force, the elastic element is in a compressed state, and the end of the locking rod retracts into the groove, disengaging from the arc-shaped limiting groove. When rotating to the next arc-shaped limiting groove, the elastic element is in a restored state, and the end of the locking rod extends out of the groove and locks into the corresponding arc-shaped limiting groove, thereby adjusting the rotation angle of the rotating shaft within the rotating groove, and thus realizing the adjustment and fixed limiting of the tilt angle between the fixed angle plate and the positioning device body.

[0007] A further improvement is that strip-shaped grooves are formed on the side walls of opposite sides within the groove, and an anti-detachment slider is provided on the outer side of the engaging rod, with the end of the anti-detachment slider movably disposed within the strip-shaped groove. In use, the sliding engagement between the anti-detachment slider on the outer side of the engaging rod and the strip-shaped groove inside the groove makes the extension and retraction movement of the engaging rod within the groove more stable, thereby ensuring the accuracy of the engaging rod end when it engages and limits the arc-shaped limiting groove.

[0008] A further improvement is that the locator body is a surgical dressing, and the locator body has a square or rectangular structure. Using a surgical dressing allows for better integration with the patient's body, facilitates positioning, and is convenient to use. Furthermore, the surgical dressing also has anti-inflammatory, hemostatic, and analgesic effects.

[0009] A further improvement is that the lower end face of the locator body is provided with an adhesive layer, and the surface of the adhesive layer is provided with release paper. In use, the release paper is peeled off, and the lower end face of the locator body is firmly fixed to a specific location on the patient's body by adhesive, resulting in a better fit and easier use.

[0010] A further improvement is that the angle-fixing plate has a semi-circular structure, and the upper surface of the angle-fixing plate is provided with angle scale lines. In use, the angle-fixing plate is rotated to be perpendicular to the patient's body surface, and the needle insertion angle is determined by the angle scale lines, achieving precise positioning of the puncture angle and improving the puncture success rate.

[0011] A further improvement is that the spacing between two adjacent positioning meridians is 1 cm, and the spacing between two adjacent positioning latitudes is 1 cm. The density of the positioning meridians and latitudes can be adjusted according to clinical needs to facilitate accurate location of the lesion.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the positioning meridian and positioning parallel lines set on the locator body and its upper end face are used to accurately locate the patient's lesion position with CT assistance and with the locator body as a reference. The most suitable horizontal position for puncture is accurately determined. Then, through the cooperation of the angle plate, the rotating shaft, the angle positioning component and the U-shaped mounting groove on the positioning seat, the tilt angle between the angle plate and the locator body can be adjusted and fixed. Referring to the angle scale line on the angle plate, the needle insertion angle during puncture is determined, realizing accurate three-dimensional positioning during puncture and improving the success rate of puncture.

[0022] Example 1

[0023] Embodiment 1 of the present invention provides a surface locator for lung puncture, such as... Figures 1 to 5As shown, the device includes a locator body 1, a locating seat 4, a fixed angle plate 8, a rotating shaft 10, and an angle positioning assembly. The upper surface of the locator body 1 is provided with multiple positioning warp lines 2 and multiple positioning weft lines 3. The positioning warp lines 2 and positioning weft lines 3 are arranged in a staggered pattern at equal intervals. The locator body 1 has a locating seat 4 connected to each of its two opposite sides. A U-shaped mounting groove 5 is provided on the outer side of the locating seat 4. The fixed angle plate 8 is connected to the end of the rotating shaft 10. The rotating shaft 10 is located in the U-shaped mounting groove 5, and both ends of the rotating shaft 10 are movably disposed in the rotating groove 6 located on the inner side wall of the U-shaped mounting groove 5. The rotating groove 6 has a circular cross-section. An angle positioning assembly is provided between the end of the rotating shaft 10 and the interior of the rotating groove 6. The angle positioning assembly can limit and fix the rotation angle of the rotating shaft 10 in the rotating groove 6. With the locator body 1 and the positioning meridian 2 and positioning parallel 3 set on its upper end face, the patient's lesion position is accurately located under CT assistance, using the locator body 1 as a reference. The most suitable horizontal position for puncture is accurately determined. Then, through the cooperation of the angle plate 8, the rotating shaft 10, the angle positioning component and the U-shaped mounting groove 5 on the positioning seat 4, the tilt angle between the angle plate 8 and the locator body 1 can be adjusted and fixed. Referring to the angle scale line 9 on the angle plate 8, the needle insertion angle during puncture is determined, realizing accurate three-dimensional positioning during puncture and improving the success rate of puncture.

[0024] The angle positioning component includes a locking rod 12 and an arc-shaped limiting groove 7. Multiple arc-shaped limiting grooves 7 are symmetrically opened along the circumferential direction on the inner side of the rotating groove 6. The outer sides of both ends of the rotating shaft 10 are provided with oppositely arranged grooves 11. One end of the locking rod 12 is movably installed in the groove 11, and an elastic element 13 is provided between the end of the locking rod 12 and the inside of the groove 11. The end of the locking rod 12 away from the groove 11 can be movably locked into the arc-shaped limiting groove 7. The end of the locking rod 12 that cooperates with the arc-shaped limiting groove 7 has a semi-circular structure. In use, an external force is applied to the fixed angle plate 8 to rotate it. At this time, under the action of the external force, the elastic element 13 is in a compressed state, the end of the locking rod 12 retracts into the groove 11, and the locking rod 12 disengages from the arc-shaped limiting groove 7. When rotating to the next arc-shaped limiting groove 7, the elastic element 13 is in a restored state, the end of the locking rod 12 extends out of the groove 11 and engages into the corresponding arc-shaped limiting groove 7, thereby completing the adjustment of the rotation angle of the rotating shaft 10 in the rotating groove 6, and thus realizing the adjustment and fixed limiting of the tilt angle between the fixed angle plate 8 and the positioning body 1.

[0025] The groove 11 has strip-shaped grooves 14 on its opposite sidewalls, and the locking rod 12 has an anti-detachment slider 15 on its outer side, with the end of the anti-detachment slider 15 movably disposed within the strip-shaped groove 14. In use, the sliding engagement between the anti-detachment slider 15 on the outer side of the locking rod 12 and the strip-shaped groove 14 inside the groove 11 makes the extension and retraction of the locking rod 12 within the groove 11 more stable, thus ensuring the accuracy of the locking rod 12's end engaging and limiting with the arc-shaped limiting groove 7.

[0026] The locator body 1 is a surgical dressing, and it has a square or rectangular structure. In this embodiment, the locator body 1 is a rectangular structure. Using a surgical dressing allows for better integration with the patient's body, facilitates positioning, and is convenient to use. Furthermore, the surgical dressing also has anti-inflammatory, hemostatic, and analgesic effects.

[0027] The locator body 1 has an adhesive layer on its lower end face, and a release liner is placed on the surface of the adhesive layer. In use, the release liner is peeled off, and the lower end face of the locator body 1 is securely fixed to a specific location on the patient's body using the adhesive. This provides a better fit and makes the device easier to use.

[0028] The angle-fixing plate 8 has a semi-circular structure, and the upper surface of the angle-fixing plate 8 is provided with angle scale lines 9. In use, the angle-fixing plate 8 is rotated to be perpendicular to the patient's body surface, and the angle of needle insertion during puncture is determined by the angle scale lines 9, which realizes the precise positioning of the puncture angle and improves the success rate of puncture.

[0029] The spacing between two adjacent positioning meridians 2 is 1 cm, and the spacing between two adjacent positioning parallels 3 is 1 cm. The density of the positioning meridians 2 and parallels 3 can be adjusted according to clinical needs to facilitate accurate location of the lesion.
