Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a dermatological wart excision device. Background Technology

[0002] Warts are benign growths of the squamous epithelium of the skin caused by human papillomavirus (HPV) infection, manifesting as wart-like growths on the skin. Approximately 80 types of HPV are associated with human diseases, with different types of warts corresponding to different HPV types. The virus mainly enters the body through breaks in the skin or mucous membranes; direct or indirect contact with the wart can lead to infection. HPV infection can cause abnormal proliferation and differentiation of skin cells.

[0003] Clinical treatment of warts (such as common warts and plantar warts) requires both precise excision and wound control. However, existing mechanical excision devices (such as patent CN218279746U) lack a rapid cutting mechanism, and the cutting is easily deviated due to patient movement during the operation. Therefore, in order to solve the aforementioned problems, we propose a dermatological wart excision device. Utility Model Content

[0004] The purpose of this invention is to address the deficiencies in the existing technology by proposing a dermatological wart excision device.

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

[0006] A dermatological wart excision device includes a housing, a lead screw is installed through the right side of the housing, a blade holder is fixedly installed at one end of the lead screw inside the housing, and blade grooves are provided on the front, back and right sides of the housing. A blade is slidably installed in the housing through the blade grooves, and the blade abuts against one side of the blade holder.

[0007] The bottom of the box is provided with a plurality of circular holes of gradually decreasing diameter at equal intervals, and the plurality of slots and the plurality of circular holes are arranged alternately.

[0008] A mounting plate is fixedly installed on the right end of the lead screw, and two springs are fixedly installed on the left side of the mounting plate. One end of each of the two springs is fixedly connected to the right side of the box body.

[0009] Furthermore, multiple slots are equally spaced on both the front and rear sides of the box body, and a baffle is installed on the box body through the slots. The baffle is located on the left side of the blade.

[0010] Furthermore, the left side of the top of the box is an open structure, and the right side of the top of the box is provided with anti-slip texture.

[0011] Furthermore, a nut is threaded onto the outer surface of the lead screw, and the nut is located on the outside of the housing.

[0012] Furthermore, a pull ring is fixedly installed on the right side of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When it is necessary to remove a raised wart on the patient's skin, first disinfect the device and the patient's skin, and anesthetize the wart area. Then, select a round hole of appropriate size to align with the wart, and simultaneously press the box down on the skin surface, allowing the protruding wart to enter the box through the round hole. By controlling the downward pressure, the exposure of healthy skin can be reduced. Next, pull the screw through the pull ring, which in turn moves the blade away from the round hole. Finally, release the screw, at which point the spring will quickly pull the mounting plate to reset the screw, and the screw will quickly push the blade to cut the wart, achieving rapid removal of the wart in a short time, limiting the removal time to within 0.5 seconds, and reducing patient pain and movement interference.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Reference Figure 1-3A dermatological wart excision device includes a housing 1. A lead screw 2 is installed through the right side of the housing 1. A blade holder 8 is fixedly installed at one end of the lead screw 2 inside the housing 1. Blade grooves 6 are provided on the front, back, and right sides of the housing 1. Blade 7 is slidably installed on the housing 1 through the blade grooves 6, and the blade 7 abuts against one side of the blade holder 8. Multiple round holes 11 with gradually decreasing diameters are equally spaced at the bottom of the housing 1. Multiple slots 9 are spaced apart from the multiple round holes 11. An installation plate 3 is fixedly installed at the right end of the lead screw 2. Two springs 5 ​​are fixedly installed on the left side of the installation plate 3. One end of each spring 5 is fixedly connected to the right side of the housing 1. A pull ring 4 is fixedly installed on the right side of the installation plate 3.

[0022] When it is necessary to remove a protruding wart on the patient's skin surface, first disinfect the device and the patient's skin, and anesthetize the wart area. Then, select a round hole 11 of appropriate size corresponding to the wart, and simultaneously press the box 1 down on the skin surface, so that the protruding wart enters the interior of the box 1 through the round hole 11. By controlling the downward pressure, the exposure of healthy skin can be reduced. Then, pull the screw 2 through the pull ring 4, which drives the blade 7 to move away from the round hole 11. Finally, release the screw 2. At this time, the spring 5 will quickly pull the mounting plate 3 to reset the screw 2. The screw 2 will quickly push the blade 7 to cut the wart, achieving rapid removal of the wart in a short time, limiting the removal time to within 0.5 seconds, and reducing patient pain and movement interference.

[0023] Multiple slots 9 are equally spaced on both the front and back sides of the box body 1. A baffle 10 is installed on the box body 1 through the slots 9. The baffle 10 is located on the left side of the blade 7. The baffle 10 can work with the blade 7 to completely cut the wart off from the patient's skin.

[0024] The top left side of the box 1 has an opening structure, and the top right side of the box 1 has anti-slip texture. The opening allows for easy observation of the wart's location through the round hole 11, making it easy to align the round hole 11 with the wart. The anti-slip texture also makes it easy to pick up the box 1.

[0025] A nut 12 is threaded on the outer surface of the lead screw 2. The nut 12 is located on the outside of the housing 1. By rotating the nut 12, the nut 12 can be moved, thereby controlling the length of the lead screw 2 extending into the housing 1, thus accurately controlling the cutting position of the blade 7.
