Description
Technical Field
[0001] This invention relates to the field of skin treatment technology, specifically to an auxiliary device for cutting warts in dermatology. Background Technology
[0002] Warts are benign growths caused by human papillomavirus (HPV) infection of skin or mucous membrane epithelial cells. Their core pathological feature is the abnormal proliferation of epithelial cells induced by the virus, forming growths protruding from the skin surface. Warts have a rough surface and diverse shapes, which not only affect the appearance of the skin, but can also cause pain or itching due to friction or pressure. Some warts are highly contagious and can be spread through direct contact or contaminated objects, and may even induce self-inoculation and spread.
[0003] In dermatological treatment of warts, surgical excision remains an important method for treating large warts that are unresponsive to drug or physical therapy. However, in current excision procedures, warts often grow on irregular skin surfaces, making them prone to wobbling during manual support or simple fixing mechanisms, resulting in low precision in controlling the cutting depth. Furthermore, existing devices are difficult to adapt to warts of different locations and sizes, making it difficult to accurately control the cutting depth and range. Wart bases are often slightly raised, and simple planar cutting can easily leave root tissue, leading to recurrence. The clamping mechanisms of conventional wart cutting auxiliary devices are mostly parallel-joining designs, which do not provide sufficient coverage of the wart, and the cutting is prone to positioning deviation due to tissue slippage, especially for raised or irregularly shaped warts, where stability is poor. Summary of the Invention
[0004] The purpose of this invention is to provide an auxiliary device for cutting warts in dermatology, which solves the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for cutting warts in dermatology, including a fixed base, with self-locking wheels fixedly installed on the lower surfaces of the four ends of the fixed base, a housing fixedly installed on the upper surface of the center of the fixed base, and a hydraulic cylinder fixedly installed on the inner bottom wall of the housing; the auxiliary device for cutting warts in dermatology also includes a cutting clamp.
[0006] The output end of the hydraulic cylinder is fixedly connected to a lifting mechanism, so that the cutting clamp moves up and down in the vertical direction, and during the up and down movement, the cutting clamp is steadily adjusted by multi-stage guides.
[0007] An adjustment mechanism is connected to the lifting mechanism so that after the cutting clamp has completed the lifting adjustment, it can be further adjusted in both radial lateral movement and angular deflection.
[0008] The clamping and lifting mechanism is fixedly connected to one end of the adjusting mechanism. It performs radial engagement movement of the cutting clamp plate through bidirectional thread transmission, and simultaneously clamps and lifts the two sides of the wart at an upward angle towards the center point through a synchronous linkage oblique hinge structure.
[0009] Optionally, the stabilizing mechanism includes:
[0010] A lifting plate is fixedly installed at the output end of the hydraulic cylinder. A lifting frame is fixedly connected to the side surface of the lifting plate away from the hydraulic cylinder. A central sliding groove and a set of auxiliary sliding grooves are respectively opened on one side surface of the housing. The auxiliary sliding grooves are symmetrically opened on both sides of the central sliding groove. The lifting plate slides inside the central sliding groove.
[0011] Each of the auxiliary slide grooves is slidably connected to an auxiliary slider, which is fixedly connected to both sides of the lifting frame.
[0012] Optionally, the adjustment mechanism includes:
[0013] The limiting screw has a convex adjustment groove inside the lifting frame. The limiting screw limits the rotation inside the convex adjustment groove. A rotating handle is fixedly connected to the end of the limiting screw away from the housing. The rotating handle extends through to the outside of the lifting frame. A convex sleeve slide is threaded on the external thread surface of the limiting screw. A telescopic slide is fixedly connected to the upper surface of the convex sleeve slide.
[0014] A rotating seat is fixedly installed on the upper surface of the telescopic slide away from the convex sleeve slide, and a rotating arm is hinged inside the rotating seat.
[0015] Optionally, the clamping mechanism includes:
[0016] A first fixed seat is fixedly connected to the side surface of the rotating arm away from the convex sleeve slide. A first connecting frame is fixedly connected to the upper surface of the first fixed seat. A second fixed seat is fixedly connected to the lower surface of one end of the first connecting frame. The first fixed seat and the second fixed seat are symmetrically distributed on the same radial horizontal line. A bidirectional screw is rotatably connected between the first fixed seat and the second fixed seat through a rolling bearing. The two ends of the bidirectional screw pass through and extend to the outer sides of the first fixed seat and the second fixed seat, respectively. The two ends of the bidirectional screw are axially positioned by a shoulder and a nut. The bidirectional screw has threaded surfaces in opposite directions on the outer surfaces of the two sides near the first fixed seat and the second fixed seat, respectively. A rotating sleeve is fixedly sleeved on the middle surface of the bidirectional screw. The outer circumferential surface of the rotating sleeve has anti-slip texture, and its axial sides are fixed to the bidirectional screw by retaining rings. Threaded sleeve blocks are threadedly sleeved on the threaded surfaces of the two sides of the bidirectional screw.
[0017] The lower surfaces of the first fixed seat and the second fixed seat are both connected to L-shaped support rods. A limiting light rod is fixedly connected to one side surface of the L-shaped support rod. A sliding block is sleeved on the outer rod part of the limiting light rod. A hinge seat is fixedly installed on the upper surface of the sliding block and the lower surface of the threaded sleeve block. A first hinge rod and a second hinge rod are hinged between the hinge seats.
[0018] The lower surface of each sliding block is connected to a second connecting frame, and the cutting clamp is symmetrically fixedly connected to one end of the second connecting frame.
[0019] Optionally, a rubber pad is attached to the recessed clamping surface of the cutting clamp.
[0020] Optionally, a pusher frame is fixedly installed on the side of the housing away from the cutting clamp.
[0021] Optionally, a cabinet is fixedly installed on the other side of the housing by the fixed base, and drawers of different sizes are slidably connected inside the cabinet.
[0022] Optionally, the surface of the lifting frame that fits into the central slide groove is larger than the groove surface of the central slide groove.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0024] First, the stabilizing lifting mechanism of this invention, through a multi-stage guiding structure of a central slide groove and two auxiliary slide grooves on both sides, combined with the drive of a hydraulic cylinder, achieves smooth lifting and lowering of the cutting clamp plate in the vertical direction, avoiding the swaying problem of traditional single-rail guides, thereby reducing the adjustment error of the cutting height. Second, the adjustment mechanism, through the combination of a limit screw, a rotating seat and a rotating arm, superimposes radial lateral movement and angular deflection on the basis of lifting and lowering adjustment, which can accurately adapt to the cutting needs of warts in different parts of the face, limbs and other areas.
[0025] Second, the clamping mechanism of this invention adopts a design of bidirectional threaded transmission and oblique hinge linkage, which enables the bidirectional screw to drive the threaded sleeve block to engage, and simultaneously drives the L-shaped support rod to obliquely retract through the first and second hinge rods. This achieves oblique upward clamping of both sides of the wart and lifting of the center point, thereby causing the upper end of the wart to gradually move away from the base of the wart, expanding the cutting field of the wart. In addition, the clamping force of the clamping mechanism is uniform and has strong wrapping properties, thus effectively preventing tissue slippage.
[0026] In addition, the built-in rubber pads in the cutting clamp further enhance friction and reduce the risk of crushing injuries. Attached Figure Description

Detailed Implementation
[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Example 1, please refer to Figures 1 to 8 The present invention provides a technical solution: an auxiliary device for cutting warts in dermatology, including a fixed base 1, with self-locking wheels 2 fixedly installed on the lower surfaces of the four ends of the fixed base 1, a housing 3 fixedly installed on the upper surface of the center of the fixed base 1, and a hydraulic cylinder 7 fixedly installed on the inner bottom wall of the housing 3. The auxiliary device for cutting warts in dermatology also includes a cutting clamp 33.
[0038] The output end of the hydraulic cylinder 7 is fixedly connected to a lifting mechanism so that the cutting clamp 33 moves up and down in the vertical direction, and during the up and down movement, the cutting clamp 33 is steadily adjusted by multi-stage guides.
[0039] The adjustment mechanism is connected to the lifting mechanism so that after the cutting clamp 33 completes the lifting adjustment, it can be further adjusted in both radial lateral movement and angular deflection.
[0040] The clamping and lifting mechanism is fixedly connected to one end of the adjusting mechanism. It performs radial engagement of the cutting clamp 33 through bidirectional thread transmission, and simultaneously clamps and lifts the two sides of the wart at an angle upward towards the center point through a synchronous linkage oblique hinge structure.
[0041] More specifically, the overall operation flow of this embodiment is as follows:
[0042] Equipment movement and fixation: The cutting auxiliary device is pushed to the operation position close to the patient by the self-locking wheels 2 at the four ends of the fixed base 1. After reaching the operation position, the brake pedal of the self-locking wheel 2 is stepped down to fix it, ensuring that the equipment does not move during the operation.
[0043] Height adjustment of cutting clamp 33: The hydraulic cylinder 7 inside the housing 3 is activated through the start panel of the housing 3. The output end of the hydraulic cylinder 7 pushes the lifting mechanism to drive the cutting clamp 33 to rise and fall in the vertical direction. During the vertical rise and fall, the cutting height is steadily adjusted through multi-stage guidance, thereby reducing errors and avoiding the shaking problem of traditional single-rail guidance.
[0044] Radial and Angle Adjustment: Operate the adjustment mechanism, first adjust the radial lateral movement, and then adjust the angular rotation to adapt to the cutting angle requirements of warts in complex areas such as the face and between the fingers.
[0045] Wart clamping and lifting: Through the bidirectional threaded transmission of the clamping mechanism and the synchronously driven oblique hinge structure, the cutting clamping plates 33 are driven to obliquely close together, so that the cutting clamping plates 33 clamp the two sides of the wart at an oblique upward angle towards the center point. The lifting action exposes the base of the wart and expands the cutting field of view.
[0046] Furthermore, institutions that steadily increase profits include:
[0047] The lifting plate 8 is fixedly installed at the output end of the hydraulic cylinder 7. The lifting plate 8 is fixedly connected to the lifting frame 9 on the side surface away from the hydraulic cylinder 7. The side surface of the housing 3 is respectively provided with a central slide groove 10 and a set of auxiliary slide grooves 11. The auxiliary slide grooves 11 are symmetrically opened on both sides of the central slide groove 10. The lifting plate 8 slides inside the central slide groove 10.
[0048] Auxiliary sliders 12 are slidably connected in the auxiliary slide grooves 11, and the auxiliary sliders 12 are fixedly connected to the two side surfaces of the lifting frame 9.
[0049] It is worth noting that when the lifting mechanism is in operation, the output end of its hydraulic cylinder 7 pushes the lifting plate 8 to move up and down synchronously. At this time, the lifting plate 8 slides vertically along the central slide groove 10 of the housing 3, driving the lifting frame 9 to move up and down synchronously, thereby achieving a rough adjustment of the height of the cutting clamp 33.
[0050] During this period, the lifting frame 9 will also drive the auxiliary sliders 12 on both sides to move up and down synchronously. The auxiliary sliders 12 on both sides slide in the auxiliary slide groove 11, forming a three-point guide structure of "one main and two auxiliary" with the central slide groove 10, so as to ensure that there is no tilting or swaying during the lifting process, improve the stability of the cutting height adjustment, and reduce the deviation of verticality.
[0051] Furthermore, the regulating mechanism includes:
[0052] The limiting screw 14 has a convex adjustment groove 13 inside the lifting frame 9. The limiting screw 14 is limited to rotate inside the convex adjustment groove 13. The end of the limiting screw 14 away from the housing 3 is fixedly connected to a rotating handle 15. The rotating handle 15 extends to the outside of the lifting frame 9. The outer thread surface of the limiting screw 14 is threaded with a convex sleeve slide 16. The upper surface of the convex sleeve slide 16 is fixedly connected to a telescopic slide 17.
[0053] A rotating seat 18 is fixedly installed on the upper surface of the telescopic slide 17 on the side away from the convex sleeve slide 16, and a rotating arm 19 is hinged inside the rotating seat 18.
[0054] It is worth noting that when adjusting the bidirectional adjustment mechanism, firstly, the rotating handle 15, which extends to the outside of the stabilizing frame 9, is rotated. The rotating handle 15 drives the limiting screw 14 to rotate within the convex adjustment groove 13, causing the convex sleeve slide 16, which is threadedly connected to the limiting screw 14, to move radially along the groove. The convex sleeve slide 16 will also synchronously drive the telescopic slide 17 to move radially, achieving precise positioning of the cutting clamp 33 in the horizontal direction. The extension length of the cutting clamp 33 is adjusted by the telescopic slide 17, and then the rotating arm 19 is deflected around the hinge point by the rotating seat 18, achieving multi-angle coverage of the cutting clamp 33 in three-dimensional space, thereby adapting to the location of the warts in patients with different body positions.
[0055] Furthermore, the clamping mechanism includes:
[0056] A first fixed seat 20 is fixedly connected to the surface of the rotating arm 19 away from the convex sleeve slide 16. A first connecting frame 21 is fixedly connected to the upper surface of the first fixed seat 20, and a second fixed seat 22 is fixedly connected to the lower surface of one end of the first connecting frame 21. The first fixed seat 20 and the second fixed seat 22 are symmetrically distributed on the same radial horizontal line. A bidirectional screw 23 is rotatably connected between the first fixed seat 20 and the second fixed seat 22 through a rolling bearing. The two ends of the bidirectional screw 23 pass through... It extends to the outside of the first fixed seat 20 and the second fixed seat 22, and the two ends of the bidirectional screw 23 are axially positioned by the shaft shoulder and nut. The two sides of the bidirectional screw 23 are respectively provided with threaded surfaces in opposite directions on the outer surfaces of the first fixed seat 20 and the second fixed seat 22. The middle end surface of the bidirectional screw 23 is fixedly sleeved with a rotating sleeve 24. The outer circumferential surface of the rotating sleeve 24 is provided with anti-slip texture, and its two axial sides are fixed to the bidirectional screw 23 by retaining rings. The two sides of the bidirectional screw 23 are respectively threaded with threaded sleeve blocks 25.
[0057] The lower surfaces of the first fixed seat 20 and the second fixed seat 22 are both connected to L-shaped support rods 26. A limiting light rod 27 is fixedly connected to one side surface of the L-shaped support rod 26. A sliding block 28 is sleeved on the outer rod part of the limiting light rod 27. A hinge seat 29 is fixedly installed on the upper surface of the sliding block 28 and the lower surface of the threaded sleeve block 25. A first hinge rod 30 and a second hinge rod 31 are hinged between the hinge seats 29.
[0058] The lower surface of the sliding block 28 is connected to the second connecting frame 32. The cutting clamp 33 is symmetrically fixed to one end of the second connecting frame 32. The recessed clamping surface of the cutting clamp 33 is fitted with a rubber pad 34.
[0059] It is worth noting that when using the clamping and lifting mechanism to clamp and lift the wart at an angle upwards towards the center point from both sides, firstly, align the concave clamping surface of the cutting clamp 33 with the center sides of the wart. Then, the operator rotates the bidirectional screw 23 and the rotating sleeve 24, causing the bidirectional screw 23 to rotate around its own axis. Since the threads of the bidirectional screw 23 on both sides of the rotating sleeve 24 have opposite directions of rotation, and the threaded sleeve 25 is constrained by the limiting light rod 27 and cannot rotate circumferentially, the threaded sleeve 25 moves relatively closer or further away from the axis of the bidirectional screw 23 under the action of the threaded pair. The threaded sleeve 25 and the sliding sleeve 28 are connected by the hinge seat 29. While the threaded sleeve 25 moves relative to the other side along the axis, it pulls the first hinge rod 30 and the second hinge rod 31 to perform a hinged movement with the included angle gradually decreasing, thereby driving the sliding sleeve 28 to slide relative to the limiting light rod 27. See Appendix Figure 6 One side of the threaded sleeve 25 is slidably sleeved with the limiting light rod 27, thereby restricting its circumferential rotation through external constraints and ensuring that the threaded transmission is converted into axial movement.
[0060] Next, the sliding block 28 drives the second connecting frame 32 and the cutting clamp 33 to retract towards the center. At the same time, the oblique angle of the L-shaped support rod 26 decomposes the clamping force into a horizontal resultant force and a vertical lifting force, thereby clamping the wart from both sides towards the center point at an oblique upward direction and slightly lifting the base of the wart to reduce damage to the surrounding tissue during cutting.
[0061] In addition, the rubber pad 34 on the concave surface of the cutting clamp 33 makes flexible contact with the surface of the wart, which increases friction to prevent slippage and avoids tissue damage caused by rigid clamping. Furthermore, the power transmission method is clearly defined by "flat key connection" and "retaining ring fixation", ensuring that the rotating sleeve 24 and the bidirectional screw 23 rotate synchronously without relative displacement.
[0062] Example 2, based on the above examples:
[0063] Furthermore, a pusher bracket 4 is fixedly installed on the side surface of the housing 3 away from the cutting clamp 33, and a cabinet 5 is fixedly installed on the other side upper surface of the housing 3, with drawers 6 of different sizes slidably connected inside the cabinet 5.
[0064] More specifically, in this embodiment, the pusher frame 4 on the side of the housing 3 is pushed, and the self-locking wheel 2 enables convenient transportation of the device, adapting to the needs of multiple scenarios such as outpatient clinics and operating rooms;
[0065] The cabinet 5 on the fixed base 1 has drawers 6 of different sizes built in, which can be used to store consumables such as cutting knives, disinfectants, and gauze in a classified manner, reducing the time for retrieving instruments during surgery and improving operational efficiency.
[0066] In addition, the surface size of the lifting frame 9 that fits into the central slide groove 10 is larger than the groove surface of the central slide groove 10.
[0067] Therefore, the surface dimension of the lifting frame 9 that fits into the central slide groove 10 is larger than the groove dimension of the central slide groove 10, forming a mechanical limiting structure. When the lifting plate 8 drives the lifting frame 9 to rise and fall to the limit position, the edge of the lifting frame 9 fits into the surface of the shell 3, avoiding equipment failure caused by the frame detaching from the slide groove and improving the safety of surgical operations.
[0068] The specific auxiliary workflow for cutting is as follows:
[0069] First, the device is easily transported by the pusher frame 4 and the self-locking wheel 2. After pushing the cutting auxiliary device to the operation position close to the patient and reaching the operation position, the brake pedal of the self-locking wheel 2 is stepped down to complete the fixation. According to the cutting needs, the cutting knife, disinfectant, gauze and other consumables are taken out from the drawer 6 of the cabinet 5.
[0070] Subsequently, the hydraulic cylinder 7 inside the housing 3 is activated through the start panel of the housing 3. The output end of the hydraulic cylinder 7 pushes the lifting plate 8 to move up and down synchronously. At this time, the lifting plate 8 slides vertically along the central slide groove 10 of the housing 3, driving the stabilizing frame 9 to move up and down synchronously. During this period, the stabilizing frame 9 will also drive the auxiliary sliders 12 on both sides to move up and down synchronously. The auxiliary sliders 12 on both sides slide in the auxiliary slide groove 11, forming a three-point guide structure of "one main and two auxiliary" with the central slide groove 10, so as to ensure that there is no tilting or swaying during the lifting process, improve the stability of the cutting height adjustment, and reduce the deviation of verticality.
[0071] Next, the rotating handle 15, which extends through the outside of the stabilizing frame 9, is rotated. The rotating handle 15 drives the limiting screw 14 to rotate within the convex adjustment groove 13, causing the convex sleeve slide 16, which is threadedly connected to the limiting screw 14, to move radially along the groove. The convex sleeve slide 16 will also drive the telescopic slide 17 to move radially in sync, achieving precise positioning of the cutting clamp 33 in the horizontal direction. The extension length of the cutting clamp 33 is adjusted by the telescopic slide 17, and the rotating arm 19 is deflected around the hinge point by the rotating seat 18, achieving multi-angle coverage of the cutting clamp 33 in three-dimensional space, thereby adapting to the location of the warts in patients in different positions.
[0072] Finally, align the concave clamping surface of the cutting clamp 33 with the center of the wart on both sides, and rotate the rotating sleeve 24 at the middle end of the bidirectional screw 23. Since the thread directions on both sides of the bidirectional screw 23 are opposite, the bidirectional screw 23 drives the threaded sleeve block 25 to move relative to each other along the axial direction. The threaded sleeve block 25 and the sliding sleeve block 28 are connected by the hinge seat 29. While the threaded sleeve block 25 moves relative to each other along the axial direction, it pulls the first hinge rod 30 and the second hinge rod 31 to perform a hinge movement with the included angle gradually decreasing. This drives the sliding sleeve block 28 to slide relative to each other along the limiting light rod 27. The sliding sleeve block 28 drives the second connecting frame 32 and the cutting clamp 33 to retract towards the center. At the same time, the oblique angle of the L-shaped support rod 26 decomposes the clamping force into a horizontal resultant force and a vertical lifting force. The rubber pad 34 on the concave surface of the cutting clamp 33 makes flexible contact with the surface of the wart, realizing the clamping of the wart on both sides towards the center point in an oblique upward direction, and slightly lifting the base of the wart to reduce damage to the surrounding tissues during cutting.
[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
