Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a dermatoscope lens adjustment device. Background Art

[0002] A dermatoscope is a medical device used to observe the patient's skin surface and underlying tissues. During the patient's skin treatment process, the staff usually uses a dermatoscope to observe the patient's skin so that the staff can determine the next treatment steps. However, when observing the patient's skin, the current dermatoscope is not convenient for adjusting the magnification of the lens, which is not conducive to the staff's more detailed observation. In addition, the current dermatoscope is not convenient for adjusting the observed skin range, which is not conducive to the staff's more accurate observation of the skin, thereby reducing the observation efficiency. Summary of the invention

[0005] Optionally, the magnification adjustment assembly includes a threaded barrel, a threaded groove is formed on the outer wall of the threaded barrel, the threaded barrel is slidably connected to the fixed barrel, the threaded barrel is located in the through hole of the outer frame, a convex lens 2 is fixedly connected inside the threaded barrel, a rubber ring is fixedly connected to the threaded barrel, an adjustment disk is rotatably connected to the outer frame, a sliding shaft is fixedly connected to the inner wall of the adjustment disk, and the sliding shaft is slidably connected to the threaded groove of the threaded barrel.

[0006] Optionally, a scale bar is provided on the adjustment disk.

[0007] Optionally, the field of view adjustment component includes a sliding plate, and the two sliding plates are respectively slidably connected to the two sliding grooves of the outer frame, and the two sliding plates are each provided with a trapezoidal sliding groove. Two extrusion plates are slidably connected to the outer frame, and protrusions are provided on both sides of the bottom of the two extrusion plates. The two protrusions of the extrusion plates are respectively slidably connected to the trapezoidal sliding grooves of the two sliding plates, and an extrusion rod is fixedly connected to one side of one of the extrusion plates, and the extrusion rod is slidably connected to the limiting groove of the outer frame.

[0008] Optionally, rubber blocks are further included, and a plurality of the rubber blocks are fixedly connected to the bottom of the outer frame.

[0009] Beneficial effects: 1. The utility model rotates the adjusting disk, and the rotation of the adjusting disk drives the sliding shaft to rotate. The rotation of the sliding shaft squeezes the threaded groove of the threaded barrel, thereby driving the threaded barrel to move upward. The upward movement of the threaded barrel increases the distance between the convex lens 2 and the convex lens 1, thereby increasing the magnification of the skin part, so that the staff can observe the patient's skin part more carefully.

[0010] 2. The utility model drives one of the squeezing plates to move by moving the squeezing rod.

[0022] The adjusting disk 9 is provided with a scale bar, and the scale bar of the adjusting disk 9 is used for the staff to record the magnification of the skin conveniently.

[0023] The field of view adjustment component includes a sliding plate 10, and the two sliding plates 10 are respectively slidably connected to the two slide grooves of the outer frame 2, and the two sliding plates 10 are each provided with a trapezoidal slide groove. Two extrusion plates 11 are slidably connected inside the outer frame 2, and both sides of the bottom of the two extrusion plates 11 are provided with protrusions, and the two protrusions of the extrusion plates 11 are respectively slidably connected to the trapezoidal slide grooves of the two sliding plates 10, and the protrusions of the extrusion plates 11 are used to squeeze the trapezoidal slide grooves of the sliding plates 10, and an extrusion rod 12 is welded on one side of one of the extrusion plates 11, and the extrusion rod 12 is slidably connected to the limiting groove of the outer frame 2, and the extrusion rod 12 is used to drive the extrusion plate 11 to move.

[0024] It also includes rubber blocks 13. Several of the rubber blocks 13 are fixedly connected to the bottom of the outer frame 2. The rubber blocks 13 are used to stabilize the outer frame 2 so that it is not easy to move during observation.

[0025] First, the staff holds the hand lever 1 and places the outer frame 2 on the patient's skin to be observed, and then observes through the through hole of the outer frame 2. In this way, the skin part to be observed will be magnified by the convex lens 1 4 and the convex lens 2 6. When the staff needs to observe the skin part more carefully, the staff turns the adjusting disk 9. The rotation of the adjusting disk 9 will drive the sliding shaft 8 to rotate. The rotation of the sliding shaft 8 will squeeze the thread groove of the threaded barrel 5, thereby driving the threaded barrel 5 to move upward. The upward movement of the threaded barrel 5 will increase the distance between the convex lens 2 6 and the convex lens 1 4, thereby increasing the magnification of the skin part, thereby enabling the staff to observe the patient's skin part more carefully, thereby improving the observation efficiency. When the part to be observed is small, the staff pushes the squeezing rod 12 to move. The movement of the squeezing rod 12 will drive one of the squeezing plates 11 to move. The protrusion of the squeezing plate 11 will squeeze the trapezoidal grooves of the two sliding plates 10, thereby driving the two sliding plates 10 When the two extrusion plates 11 and the two sliding plates 10 move in the direction of approaching each other, the movement of the trapezoidal grooves of the two sliding plates 10 will squeeze the two protrusions of the other extrusion plate 11 respectively, thereby driving the other extrusion plate 11 to move in the direction of the extrusion rod 12. In this way, the two extrusion plates 11 and the two sliding plates 10 move in the direction of approaching each other, thereby blocking the edge of the convex lens 4, thereby reducing the observed skin range, thereby enabling the staff to observe the skin more accurately, thereby improving the observation efficiency. When the observation is completed, the staff will rotate the adjusting disk 9 in the opposite direction to its original position. The reverse rotation of the adjusting disk 9 will drive the threaded cylinder 5 and the convex lens 2 6 to reset downward together through the sliding shaft 8. Then the staff will pull the pull rod to reset one of the extrusion plates 11. The reset of the extrusion plate 11 will reversely squeeze the trapezoidal grooves of the two sliding plates 10, thereby driving the two sliding plates 10 to reset. The reset of the two sliding plates 10 will cause the other extrusion plate 11 to reset. At the same time, the staff will remove the outer frame 2 from the patient's skin.
