Description

Technical Field

[0001] The present invention relates to the technical field of dermatoscope auxiliary tools, and in particular to an auxiliary bracket for a handheld confocal microscope. Background Art

[0002] Dermatoscope is also called skin surface light microscope. The English name and synonyms of dermatoscopy include. Its function is the same as that of ophthalmoscope and otoscope used in otolaryngology. It is a tool for observing skin pigment diseases.

[0003] When examining a patient's arm with an existing dermatoscope, the doctor often holds the dermatoscope in hand to observe the patient's skin. The doctor needs to keep the dermatoscope at a certain distance from the patient's skin and maintain a fixed posture for a long time during observation. However, holding the dermatoscope for a long time may cause the doctor's arm to become sore and numb. At the same time, the handheld dermatoscope has poor stability, so the doctor needs to adjust the position of the dermatoscope frequently, which is time-consuming and laborious. In addition, some existing dermatoscope brackets are usually fixed and cannot be adjusted at an angle, resulting in the device not having a certain degree of adjustability. At the same time, the handheld dermatoscope is cumbersome to install, has poor practical performance, and is inconvenient to use. Summary of the invention

The rotation of the rotating rod can move the threaded barrel up and down, and the threaded barrel drives the connecting piece and the fine-tuning mechanism to move up and down synchronously, and the fine-tuning mechanism drives the handheld dermatoscope to move up and down, thereby realizing the adjustment of the height of the handheld dermatoscope.

[0007] Furthermore, a limiting slide rod is fixedly provided on the outer side wall of the threaded barrel, and a limiting slide groove is provided on the side wall of the cavity which is parallel to the rotating rod. An end of the limiting slide rod is located inside the limiting slide groove. The setting of the limiting slide rod and the limiting slide groove serves to limit and guide the up and down movement of the threaded barrel, thereby making the up and down movement of the threaded barrel more stable.

[0008] A stabilizing plate is arranged between the inner walls of the cavity, and the rotating rod rotates through the stabilizing plate. The stabilizing plate plays a role of a fulcrum support for the rotating rod, so that the rotation of the rotating rod can be more stable.

[0009] Furthermore, a driving motor is installed on the base, a gear 1 is arranged on the output shaft of the driving motor, and a gear 2 meshing with the gear 1 is sleeved on the column.

[0010] Furthermore, an arm rest seat is provided on the upper side of the base, and a placement groove is provided on the upper side of the arm rest seat; a layer of soft material is provided on the inner wall of the placement groove. When the patient's arm needs to be examined, the arm can be placed directly in the placement groove, so that the arm is placed stably and the arm is not prone to shaking, which is beneficial to improving the detection accuracy. The soft material can be a sponge pad, etc., to increase the comfort of the patient's arm when placed.

[0011] Furthermore, the connecting member is a connecting rod, one end of which is hinged to the upper end of the threaded barrel, and the other end is welded to the fine-tuning mechanism. The connecting rod and the threaded barrel are rotatably connected by a pin, so that the connecting rod can synchronously drive the handheld dermatoscope to swing and adjust at a large angle to adapt to the detection of different positions of the patient's body.

[0012] Furthermore, the connecting member is a universal rod, and both ends of the universal rod are fixedly connected to the threaded tube and the fine-adjustment mechanism respectively. The universal rod can be made of standard parts on the market. In this way, the handheld dermatoscope can be bent and adjusted at any angle through the universal rod, thereby increasing applicability.

After the approximate detection angle is adjusted, when the detection angle needs to be fine-tuned, the knob two is turned, and the driving rod drives the bevel gear two to rotate. The bevel gear two can rotate the driving screw with the cooperation of the bevel gear one, and the driving screw can make the threaded sleeve drive the lower end of the limit slide bar two to move. The limit slide bar two can change the inclination angle of the adjustment block with the cooperation of the connecting rod and the fixed rod, and the adjustment block drives the handheld dermatoscope to adjust synchronously, thereby realizing the inclination angle adjustment of the handheld dermatoscope. Since it is driven and moved in a threaded manner, the handheld dermatoscope can be adjusted at a small distance and a small angle, which is beneficial to improve the adjustment accuracy of the handheld dermatoscope during detection.

[0014] Furthermore, a locking mechanism is provided on the L-shaped plate, and the locking mechanism is used to lock the tilt angle of the adjustment block to prevent the adjustment block from tilting for a long time or causing the thread sleeve to be stripped due to vibration or the like, thereby preventing the detection angle of the handheld dermatoscope from changing and improving stability.

[0015] The locking mechanism includes a pull rod sliding through the L-shaped plate and a circular gear arranged on the driving rod, one end of the pull rod is provided with a tooth plate meshing with the circular gear, and the other end is provided with a pull head, and a spring 1 is sleeved on the pull rod located between the tooth plate and the L-shaped plate. When in use, the pull head is pulled, and the pull head drives the tooth plate to move to one side through the pull rod, and the tooth plate is separated from the circular gear. At this time, the spring 1 is in a compressed state, and then the driving rod is rotated to adjust the detection angle of the handheld dermatoscope. When the detection angle is adjusted, the pull head is released. At this time, due to the resetting force of the spring 1, the tooth plate and the circular gear can be re-engaged, and the driving rod is locked so that it cannot rotate. Further, the detection angle of the handheld dermatoscope is locked, making it more stable during detection and there will be no irradiation deviation.

When the handheld dermatoscope needs to be installed on the bracket, the pull ring is first pulled upward, and the pull ring drives the pressing plate to move upward. At this time, the pressing plate stretches the second spring, and then the handle of the handheld dermatoscope is inserted between the pressing plate and the bottom of the notch. Then the pull ring is released. Due to the reset force of the second spring, the pressing plate can clamp the handle of the handheld dermatoscope, thereby completing the installation; Rubber pads are respectively arranged on the lower side of the pressure plate and the bottom of the notch. The rubber pads can increase the friction between the pressure plate and the handheld dermatoscope, thereby improving the installation firmness. At the same time, the rubber pads can also provide buffering and protection for the handle of the handheld dermatoscope.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The auxiliary bracket can rotate the column through the cooperation of the driving motor, gear one and gear two, and the handheld dermatoscope can rotate 360 ​​degrees through the cooperation of the connecting piece and the fine-tuning mechanism; the rotating rod can rotate by setting the adjustment rod, worm gear and worm, and the rotating rod can drive the threaded barrel to move up and down, and then drive the handheld dermatoscope to move up and down synchronously. Therefore, the above structure can realize 360-degree horizontal rotation and up and down movement of the handheld dermatoscope, and it is easy to adjust, so that multiple detection angles of the handheld dermatoscope can be adjusted over a wide range.

[0018] By setting up a fine-tuning mechanism, the handheld dermatoscope can be adjusted to a small angle. By rotating the driving rod, the driving screw can be rotated with the cooperation of bevel gear one and bevel gear two, and the driving screw drives the threaded sleeve and the limit slide rod two to move. With the cooperation of the fixed rod and the connecting rod, the inclination angle of the adjustment block can be changed, thereby adjusting the inclination angle of the handheld dermatoscope. Since micro-driving and movement are performed in a threaded manner, the handheld dermatoscope can be adjusted at a small distance and a small angle, thereby ensuring the adjustment accuracy of the handheld dermatoscope during detection.

[0019] By setting a locking mechanism, the stability of the handheld dermatoscope during operation can be enhanced. By setting a clamping mechanism, the handheld dermatoscope can be quickly and easily installed on the fixed bracket, and assembly and disassembly are very convenient. By setting a connecting piece, the handheld dermatoscope can be further provided with more angles of adjustment, so as to provide patients with more angles of detection, and the operation is convenient.
