Technical Field

[0001] This utility model belongs to the field of dermoscopy technology, specifically relating to a dermoscopy with a protective structure. Background Technology

[0002] Dermoscopy is a non-invasive diagnostic device used on the human body. It can magnify the skin and observe the color and structure of the epidermis, dermis, dermal junction, and dermal papillae, which are often difficult to see with the naked eye. Dermoscopy can significantly improve the clinical diagnostic accuracy of melanocytic, non-melanocytic, and various benign and malignant skin lesions.

[0003] Because existing handheld dermatoscopes need to come into contact with human skin, they need to be disinfected after each use to avoid viral infection between different patients. The disinfection process usually involves doctors spraying alcohol on the dermatoscope and then wiping it, which cannot guarantee thorough disinfection and increases the workload of doctors. When there are many patients, it will increase the waiting time for subsequent patients and delay the observation efficiency.

[0004] Therefore, a dermoscopy with a protective structure is needed to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a dermatoscope with a protective structure to solve the problem that in the prior art, dermatoscopes need to be disinfected and wiped after each use, which increases the waiting time for subsequent patients and delays the observation efficiency.

[0022] The following components are labeled in the attached diagram: tube 1, objective lens 101, eyepiece 102, protective sleeve 2, annular groove 201, empty groove 202, locking groove 203, sliding groove 204, notch 205, through hole 206, transparent sleeve 207, locking ring 3, locking buckle 301, second toothed ring 302, handle 4, drive ring 5, and first toothed ring 501. Detailed Implementation

[0023] like Figures 1-4 As shown, this utility model provides a dermatoscope with a protective structure, comprising: a tube 1, an objective lens 101 fixedly installed inside the tube 1 near a first end of the tube 1, an eyepiece 102 fixedly installed inside the tube 1 near a second end of the tube 1, a protective sleeve 2 detachably installed on the tube 1, the protective sleeve 2 having an annular groove 201 that mates with the first end of the tube 1, so that the cross-section of the protective sleeve 2 is J-shaped, and the tube 1 can be inserted into the annular groove 201.

[0024] In this solution, a protective sleeve 2 is installed so that the first end of the endoscope tube 1 is inserted into the annular groove 201, allowing the J-shaped protective sleeve 2 to protect both the inner and outer walls of the first end of the endoscope tube 1. When using the dermatoscope, the protective sleeve 2 is changed after each patient. Used protective sleeves 2 are placed in a recycling basket and subsequently disinfected before being reused.

[0025] This solution reduces the need for disinfection and wiping after using the dermatoscope by setting up a protective cover 2, thus reducing patient waiting time and increasing treatment efficiency.

[0026] In one embodiment of this utility model, a locking ring 3 is rotatably installed on the outer wall of the lens barrel 1. A plurality of latches 301 are arranged circumferentially around the locking ring 3. The protective sleeve 2 is provided with a slot 202 that cooperates with the locking ring 3 and a locking groove 203 that communicates with the slot 202 and cooperates with the latches 301. The protective sleeve 2 is provided with a sliding groove 204 that communicates with the locking groove 203.

[0027] In this design, when installing the protective sleeve 2, it is slid along the direction in which the latch 301 engages with the slide groove 204 until the locking ring 3 falls into the empty groove 202. Then, the locking ring 3 is rotated to allow the latch 301 to slide into the locking groove 203, thereby limiting the axial displacement of the protective sleeve 2. The latch 301 and the inner wall of the locking groove 203 are in frictional connection to improve the installation stability of the protective sleeve 2. The top walls of the locking ring 3 and the protective sleeve 2 are both located on the same plane as the second end side wall of the lens barrel 1, so that the protective sleeve 2 can cover the entire outer wall of the lens barrel 1, ensuring the protective effect on the outer wall of the lens barrel 1. The annular groove 201 is clearance-fitted with the lens barrel 1, so that when the latch 301 disengages from the locking groove 203, the protective sleeve 2 can easily detach from the lens barrel 1, reducing friction between the protective sleeve 2 and the lens barrel 1.

[0028] In one embodiment of the present invention, a handle 4 is fixedly connected to the lens barrel 1, and the protective sleeve 2 is provided with a notch 205 to avoid the handle 4. The bottom wall of the notch 205 abuts against the handle 4 so that the latch 301 abuts against the bottom wall of the slide groove 204.

[0029] In this scheme, the protective sleeve 2 is slid into the lens barrel 1 along the direction of the notch 205 and the handle 4. When the bottom wall of the notch 205 abuts against the handle 4, the latch 301 abuts against the bottom wall of the slide groove 204. At this time, the locking ring 3 is rotated, which drives the latch 301 to rotate into the locking groove 203 to lock the protective sleeve 2.

[0030] In one embodiment of this utility model, a drive ring 5 is rotatably mounted on the handle 4, a first toothed ring 501 is fixedly disposed on the drive ring 5, and a second toothed ring 302 that meshes with the first toothed ring 501 is fixedly disposed near the end of the handle 4. Rotating the drive ring 5 can cause the lock ring 3 to rotate.

[0031] In this design, the rotating drive ring 5 drives the first toothed ring 501 to rotate, which in turn drives the second toothed ring 302 to rotate, which in turn drives the locking ring 3 to rotate, so that medical staff can directly operate the fixing or unfixing of the protective sleeve 2 on the handle 4, thus improving the ease of operation.

[0032] In one embodiment of this utility model, such as Figure 3 The protective sleeve 2 is provided with a through hole 206 so that it can be observed through the objective lens 101 through the through hole 206.

[0033] In this design, the protective sleeve 2 with through holes 206 is suitable for observing the patient's skin without hair.

[0034] In one embodiment of this utility model, such as Figure 4 The protective sleeve 2 is provided with a transparent sleeve 207 with a closed through hole 206.

[0035] In this solution, the protective cover 2 with a transparent sleeve 207 is suitable for observing the patient's skin with hair, such as the scalp, to avoid the hair from coming into contact with the objective lens 101 and to reduce the disinfection and wiping work of the objective lens 101.
