Description

Technical Field

[0001] This invention relates to the field of dermatological lesion removal technology, and more specifically, to a dermatological device for removing benign skin lesions. Background Technology

[0002] Benign growths are non-cancerous abnormal tissue growths that typically grow slowly, have well-defined borders, and do not spread or metastasize. Common types of benign growths include lipomas, fibromas, and hemangiomas. Their formation is related to factors such as genetics, hormones, and local irritation. Most do not require treatment, but regular observation or surgical removal is necessary to prevent complications. In situations where laser treatment is inconvenient, curettage or excision can be used.

[0003] However, most existing dermatological devices for removing benign skin growths do not have a scraping function. When scraping growths, they usually require manual control by medical staff, which reduces the efficiency of the removal device, limits its application, and increases the workload of medical staff. Summary of the Invention

[0004] This invention provides a device for removing benign skin growths in dermatology, which solves the problem that most existing devices for removing benign skin growths in dermatology do not have a scraping function, and that the scraping of growths usually requires manual operation by medical staff.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dermatological device for removing benign skin growths includes a support and a removal assembly. The removal assembly includes a movable seat slidably connected to the bottom of the support via a telescopic rod. A rotating seat is rotatably connected to one side of the movable seat. A directional rod and a pair of locking rods are provided on the rotating seat. An end plate is slidably locked between the two locking rods. A fixed seat and a directional block are respectively connected to both ends of the end plate. The directional rod passes through the inner side of the directional block.

[0009] Preferably, the fixed rod is rotatably fitted with multiple driven wheels, and each driven wheel is coaxially connected to a rotating rod at its bottom end. The bottom end of the rotating rod is connected to a cutting blade, and all the cutting blades are staggered, with the staggered distance between the cutting blades being greater than the thickness of the cutting blade.

[0010] Preferably, a motor is connected to the bottom end of the fixed rod, and a drive wheel is coaxially connected to the output shaft end of the motor. The drive wheel simultaneously makes frictional contact with the outer sides of all the driven wheels.

[0011] Preferably, one end of the support is screwed to another connecting rod, one end of the connecting rod is connected to a fixing frame, the fixing frame has a slot, a clip is slidably engaged in the slot, a scraper is engaged between the two clips, and a magnetic block is connected to the same end of the two clips.

[0012] Preferably, the top of the support has a groove, the surface of the groove is covered with a replaceable sterile pad, and the bottom of the support is connected to a base plate through a spacing component.

[0013] Preferably, the bottom end of the support and the top end of the base are each connected to two pairs of connecting blocks. A baffle is provided on the outside of each connecting block. A rotating arm is hinged to each pair of connecting blocks. The inside of the baffle contacts the outside of the rotating arm. The free ends of a pair of rotating arms located between two connecting blocks in the same vertical direction are coaxially connected by a connecting shaft.

[0014] Preferably, the two connecting shafts at the same end are coaxially connected by a rotating cylinder. The rotating cylinder has a through hole, and a crossbar is slidably engaged between the two through holes. The two ends of the crossbar are respectively aligned with the two ends of the base plate in the vertical direction.

[0015] Preferably, one end of the crossbar is connected to an end block, a screw is threaded through the end block, and a knob is coaxially connected to the bottom end of the screw. The knob is rotated and locked onto one end of the base plate.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The removal component set in this invention can remove benign skin growths on the patient's skin surface. Compared with mainstream laser treatment, physical scraping treatment will not cause thermal damage to surrounding tissues. Therefore, compared with laser treatment, the probability of leaving scars after complete healing is lower, thereby improving the removal effect of the device. When using this device, it is necessary to first confirm the area where the patient needs to remove benign skin growths. If the area where the patient needs to remove benign skin growths is on the patient's limb, the patient can extend the limb and place it above the support. After the support is raised until the patient's limb is level with the support, the corresponding tool is selected according to the type of treatment the patient needs. When the patient needs to remove the growths, the telescopic airbag is expanded, and the fixed rod connected to the bottom of the telescopic airbag will move down synchronously, so that the pressure ring moves down further to compress the patient's limb skin until the cutting blade connected to the bottom of the rotating rod is in contact with the patient's skin surface. Then the motor is started, and the drive wheel coaxially connected to the output shaft of the motor can drive the driven wheel that is in frictional contact with its outer side to rotate, so that the driven wheel can cut the benign growths on the patient's skin surface through the cutting blade connected to the rotating rod.

[0018] (2) The distance-fixing component set in this invention can adjust the height of the support. When the height of the support needs to be adjusted, turn the knob coaxially connected to the bottom of the screw to make the knob drive the screw to rotate. The screw will drive the end block connected to one end of the crossbar to move along the screw axis. The two rotating cylinders passing through the crossbar will drive the connecting shafts connected to both ends. The connecting shafts will drive the two rotating arms hinged to them to move. During the movement of the two rotating arms, the support will move synchronously, so that the sterile pad laid at the top of the support can stably support the patient's limb.

[0026] Example:

[0027] like Figures 1 to 5 As shown, the present invention provides a dermatological device for removing benign skin growths, including a support 2 and a removal assembly. The removal assembly includes a movable seat 38 slidably connected to the bottom end of the support 2 via a telescopic rod. A rotating seat 6 is rotatably connected to one side of the movable seat 38. A directional rod 14 and a pair of locking rods 15 are provided on the rotating seat 6. An end plate 10 is slidably locked between the two locking rods 15. A fixed seat 17 and a directional block 12 are respectively connected to both ends of the end plate 10. The directional rod 14 passes through the inner side of the directional block 12. A connecting cylinder 16 is provided at the top of the fixed seat 17.

[0028] like Figure 2 and Figure 3 As shown, a pair of guide blocks 11 are provided on the inner side of the directional block 12. The two guide blocks 11 are slidably locked on the outer side of the directional rod 14. A motor 5 is provided on the rotating seat 6. A lead screw 13 is coaxially connected to the output shaft end of the motor 5. The end plate 10 passes through the outer side of the lead screw 13.

[0029] As shown in Figure x, a telescopic airbag is provided at the bottom of the inner top wall of the connecting cylinder 16. A connecting rod 21 is screwed to the bottom of the telescopic airbag. A fixing rod 22 is coaxially connected to the bottom of the connecting rod 21. Multiple support arms 18 are evenly arranged at the bottom of the fixing rod 22. Each support arm 18 is provided with an elastic button 19 at the bottom. All elastic buttons 19 are connected to a pressure ring 20 at the bottom.

[0030] like Figure 4 As shown, a plurality of driven wheels 25 are rotatably mounted on the fixed rod 22. Each driven wheel 25 is coaxially connected to a rotating rod 26 at its bottom end. A cutting blade 27 is connected to the bottom end of the rotating rod 26. All cutting blades 27 are staggered, and the staggered distance between the cutting blades 27 is greater than the thickness of the cutting blade 27.

[0031] like Figure 4 As shown, a motor 24 is connected to the bottom end of the fixed rod 22, and a drive wheel 23 is coaxially connected to the output shaft end of the motor 24. The drive wheel 23 simultaneously makes frictional contact with the outer side of all driven wheels 25.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, another connecting rod 21 is screwed to one end of the support 2. One end of the connecting rod 21 is connected to a fixing frame 33. A slot 35 is provided on the fixing frame 33. A clip 34 is slidably engaged in the slot 35. A scraper 36 is engaged between the two clips 34. A magnetic block 28 is connected to the same end of both clips 34.

[0033] like Figure 1 As shown, the top of the support 2 has a groove, and the surface of the groove is covered with a replaceable sterile pad. The bottom of the support 2 is connected to the base plate 1 through a spacing component.

[0034] like Figure 1 and Figure 5 As shown, the bottom of the support 2 and the top of the base 1 are each connected to two pairs of connecting blocks 4. A baffle 29 is provided on the outside of the connecting blocks 4. A rotating arm 37 is hinged on each pair of connecting blocks 4. The inside of the baffle 29 contacts the outside of the rotating arm 37. The free ends of a pair of rotating arms 37 located between the two connecting blocks 4 in the same vertical direction are coaxially connected by a connecting shaft 32.

[0035] like Figure 1 and Figure 5 As shown, the two connecting shafts 32 at the same end are coaxially connected by a rotating cylinder 30. A through hole 31 is provided on the rotating cylinder 30, and a crossbar 3 is slidably locked between the two through holes 31. The two ends of the crossbar 3 are respectively aligned with the two ends of the base plate 1 in the vertical direction.

[0036] like Figure 1 and Figure 2 As shown, one end of the crossbar 3 is connected to an end block 8, and a screw 7 is threaded through the end block 8. A knob 9 is coaxially connected to the bottom end of the screw 7, and the knob 9 is rotated and locked onto one end of the base plate 1.

[0037] The distance-fixing component can adjust the height of the support 2. When the height of the support 2 needs to be adjusted, turn the knob 9 coaxially connected to the bottom of the screw 7, so that the knob 9 drives the screw 7 to rotate. The screw 7 will then drive the end block 8 connected to one end of the crossbar 3 to move along the axis of the screw 7. This will cause the two rotating cylinders 30 passing through the crossbar 3 to drive the connecting shafts 32 connected to their two ends. The connecting shafts 32 will then drive the two rotating arms 37 hinged to them to move. During the movement of the two rotating arms 37, the support 2 will move synchronously, so that the sterile pad laid up to the top of the support 2 can stably support the patient's limb.

[0038] The specific usage and function of this embodiment are as follows:

[0039] The removal component in this invention can remove benign skin growths on the patient's skin surface. Compared to mainstream laser treatment, physical scraping treatment does not cause thermal damage to surrounding tissues. Therefore, compared to laser treatment, the probability of scarring after complete healing is lower, thus improving the removal effect of the device. When using this device, it is necessary to first identify the area where the benign skin growth needs to be removed. If the area is on the patient's limb, the patient can extend the limb and place it on the support 2. To allow the patient to lay the limb flat on the support 2 for growth removal, the height of the support 2 needs to be adjusted using the distance fixing component. After raising the support 2 until the patient's limb is level with the support 2, the corresponding tool is selected according to the type of treatment required by the patient. When the patient needs to remove the growth, the connecting rod 21, which is coaxially connected to the fixing rod 22, is rotated and screwed to the bottom end of the telescopic airbag connected to the bottom end of the inner top wall of the connecting cylinder 16. Then, the rotating seat 6 is rotated along one side of the moving seat. The directional rod 14 and locking rod 15 on the rotating seat 6 are moved to the vertical direction. Then, the motor 5 on the rotating seat 6 is started, causing the lead screw 13 coaxially connected to the output shaft of the motor 5 to rotate. The end plate 10 passing through the outside of the lead screw 13 will drive the fixed seat 17 and the directional block 12 connected to its two ends to move vertically, causing the end plate 10 to slide between the two locking rods 15 until the bottom end of the pressure ring 20 at the bottom end of the fixed rod 22 contacts the skin surface of the patient's limb. At this time, the motor 5 is stopped and the telescopic airbag is moved. Inflate the airbag to expand it. The fixed rod 22 connected to the bottom of the airbag will move down synchronously, causing the pressure ring 20 to move down further and compress the patient's limb skin until the cutting blade 27 connected to the bottom of the rotating rod 26 is in contact with the patient's skin surface. Then, start the motor 24. The drive wheel 23 coaxially connected to the output shaft of the motor 24 can drive the driven wheel 25, which is in frictional contact with its outer side, to rotate. The driven wheel 25 can then cut the benign growths on the patient's skin surface through the cutting blade 27 connected to the rotating rod 26.

[0040] When it is necessary to scrape off growths on the patient's skin surface, the connecting rod 21 connected to the fixed frame 33 is rotated and screwed to the bottom end of the telescopic airbag connected to the bottom end of the inner top wall of the connecting cylinder 16. Then, according to the area where the growths need to be scraped off, the position of the scraper 36 is determined. After determining the position of the scraper 36, the clips 34 that are slidably locked in the fixed frame 33 through the slots 35 are manually separated, so that the two clips 34 are separated and the clamping of the scraper 36 is stopped. After the scraper 36 is adjusted to the appropriate position, the clips 34 are released. The clips 34 will then reset under the magnetic block 28 connected to one end and clamp the scraper 36. After the position of the scraper 36 is fixed, the scraper 36 is first aligned with the outer base of the patient's skin where the growths are to be scraped off. Then, the telescopic rod is activated, so that the telescopic rod drives the moving seat to move, and the scraper 36 scrapes off the growths on the patient's skin.
