Description

Technical Field

[0001] The present invention relates to the technical field of clinical medical devices, and particularly to a clinical debridement device for dermatology. Background Art

[0002] Wound debridement is a basic treatment for skin clinical surgeries. Only by thoroughly removing necrotic tissues and putrefactive flesh can granulation tissue grow smoothly.

[0003] In the prior art, when cleaning and treating skin wound surfaces, scissors and forceps are frequently used. The putrefactive flesh at the wound is cut off with scissors, and then the forceps are switched to pick out the putrefactive flesh or other impurities from the wound surface, and then the wound surface is disinfected and bandaged after completion. However, during the initial cleaning, the frequent switching between scissors and forceps is particularly time-consuming and laborious because both are used in a clamping manner, which greatly affects the efficiency of a doctor in debriding the skin wound surface. For this reason, we propose a clinical debridement device for dermatology. Summary of the Invention

[0004] One technical problem to be solved by this application is that the frequent switching between scissors and forceps during debridement operations takes a relatively long time and affects the processing efficiency of debridement operations.

[0005] To solve the above technical problem, the embodiment of this application provides a clinical debridement device for dermatology, including a forceps arm, a forceps head and a rotating shaft. The forceps arm and the forceps head are rotationally connected through the rotating shaft, and further include:

[0006] A blade, which is arranged at one end of the forceps head;

[0007] A rotation and telescoping mechanism, which is arranged between the forceps arm and the forceps head. The position of the blade can be adjusted through the rotation and telescoping mechanism to facilitate the shearing of the blade.

[0008] In some embodiments, the interior of the forceps head is hollow, and the blade is slidably arranged inside the forceps head.

[0009] In some embodiments, the rotation and telescoping mechanism includes a rotating post, a rotating gear, a moving rack and a connecting bar. The rotating post is slidably arranged on opposite side surfaces of the rotating shaft.

[0010] In some embodiments, the rotating post is fixedly arranged on one side surface of the rotating gear, and the rotating gear is rotationally connected to the inner side wall of the forceps head.

[0011] In some embodiments, the moving rack is slidably arranged on the inner side wall of the forceps head, and one side surface of the moving rack meshes with the rotating gear.

[0012] In some embodiments, one end of the connecting bar is fixedly arranged on one side surface of the blade, and the other side surface of the connecting bar is fixedly arranged on one side surface of the moving rack.

[0013] In some embodiments, a circular hole adapted to the rotating shaft is provided at the center of the rotating gear, and the inner side wall of the rotating gear is in sliding contact with the rotating shaft.

[0014] The present invention has at least the following beneficial effects:

[0015] By providing the pliers head, the blade and the rotating telescopic mechanism, after the ordinary pliers are transformed by the rotating telescopic mechanism, they have the function of shearing, and there is no need to switch scissors during the debridement process, greatly improving the working efficiency of the debridement operation.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figures 1-4 , the present invention provides a technical solution for a dermatological clinical debridement device: a dermatological clinical debridement device, including a pliers arm 1, a pliers head 2 and a rotating shaft 3. The pliers arm 1 and the pliers head 2 are rotatably connected through the rotating shaft 3. The rotational connection between the pliers arm 1, the pliers head 2 and the rotating shaft 3 is prior art and will not be elaborated here. It also includes:

[0030] Blade 4, the blade 4 is arranged at one end of the pliers head 2;

[0031] Rotating telescopic mechanism 5, the rotating telescopic mechanism 5 is arranged between the pliers arm 1 and the pliers head 2. Through the rotating telescopic mechanism 5, the position of the blade 4 can be adjusted to facilitate the shearing of the blade 4.

[0032] The inside of the pliers head 2 is hollow. This is set to enable the blade 4 to be stored inside the pliers head 2 when not in use, avoiding accidental injury. The blade 4 is slidably arranged inside the pliers head 2. The blade 4 is provided to facilitate the shearing of impurities such as necrotic tissue in the wound surface.

[0033] The rotating telescopic mechanism 5 includes a rotating pile 501, a rotating gear 502, a moving rack 503 and a connecting bar 504. The rotating pile 501 is slidably arranged on the opposite side surfaces of the rotating shaft 3. The rotating telescopic mechanism 5 is symmetrically arranged. This is set to facilitate the control of the blade positions of the two pliers heads 2.

[0034] The rotating pile 501 is fixedly arranged on one side surface of the rotating gear 502. The rotating gear 502 is rotatably connected to the inner side wall of the pliers head 2. The rotating pile 501 is provided to control the rotation of the rotating gear 502. The rotating pile 501, the rotating gear 502, the moving rack 503 and the connecting bar 504 are all arranged inside the pliers head 2.

[0035] The movable rack 503 is slidably arranged on the inner side wall of the pliers head 2. One side surface of the movable rack 503 meshes with the rotating gear 502. The movable rack 503 is arranged to convert the rotation of the rotating gear 502 into the movement of the blade 2.

[0036] One end of the connecting bar 504 is fixedly arranged on one side surface of the blade 4, and the other side surface of the connecting bar 504 is fixedly arranged on one side surface of the movable rack 503. The connecting bar 504 is arranged to connect the movable rack 503 and the blade 2 to directly control the blade 2.

[0037] A circular hole adapted to the rotating shaft 3 is opened at the center of the rotating gear 502, and the inner side wall of the rotating gear 502 is in sliding contact with the rotating shaft 3. This setting is to prevent the rotation of the rotating gear 502 from driving the rotation of the rotating shaft 3. When the rotating shaft 3 rotates, that is, the relative rotation of the pliers arm 1 and the pliers head 2 will not affect the rotation of the rotating gear 502.

[0038] First, pass a finger through the pliers arm 1 to control the pliers head 2 to clamp and clean the impurities in the wound surface. When it is necessary to cut in the wound surface, rotate the rotating pile 501 to drive the rotation of the rotating gear 502. When the rotating gear 502 rotates, it will drive the meshing movable rack 503 to move towards one end. The movable rack 503 will then synchronously drive the blade 4 to move through the connecting bar 504, so that the blade 4 moves out from one end of the pliers head 2. At this time, the blade 4 at the front end of the pliers head 2 can be controlled by the pliers arm 1 to cut.

[0039] Embodiment 2:

[0040] Please refer to Figures 5-7 , the present invention provides a technical solution for a dermatological clinical debridement device: a dermatological clinical debridement device, including a pliers arm 1, a pliers head 2 and a rotating shaft 3. The pliers arm 1 and the pliers head 2 are rotatably connected through the rotating shaft 3, and further include:

[0041] A blade 4, the blade 4 is arranged at one end of the pliers head 2;

[0042] A rotation reversing mechanism 6, the rotation reversing mechanism 6 is arranged on the pliers head 2. Through the rotation reversing mechanism 6, the rotation direction of the blade 4 can be reversed, so as to facilitate the blade 4 to cut.

[0044] The rotation and commutation mechanism 6 includes a fixed post 601, a rotating cover 602, a rotating column 603, a limiting block 604 and a limiting groove 605. The fixed post 601 is slidably arranged at one end of the clamping head 2. The rotating cover 602 is fixedly arranged at the upper end of the rotating column 603. The fixed post 601 is provided to facilitate the rotation of the rotating column 603, and the rotating cover 602 is provided to control the rotation of the rotating column 603.

[0045] The blade 4 is fixedly arranged on the outer side wall of the rotating column 603. The rotating column 603 is rotatably connected to the clamping head 2. The rotating column 603 is rotatably arranged in the fixed post 601. The rotating column 603 is used to drive the rotation of the blade 4.

[0046] The limiting block 604 is fixedly arranged on one side surface of the rotating cover 602. The limiting groove 605 is opened on one side surface of the fixed post 601. The limiting block 604 is adapted to the limiting groove 605. The limiting block 604 and the limiting groove 605 are provided to limit the rotation of the blade 4.

[0047] First, pass a finger through the clamping arm 1 to control the clamping head 2 to clamp and clean the impurities in the wound surface. When it is necessary to perform shearing in the wound surface, move the fixed post 601 downward to make the limiting block 604 disengage from the limiting groove 605. At this time, by rotating the rotating cover 602, the rotating cover 602 will drive the rotating column 603 to rotate, and the rotating column 603 drives the blade 4 to rotate, so that the blade 4 rotates from one side of the clamping head 2 to the front end of the clamping head 2. At this time, the blade 4 at the front end of the clamping head 2 can be controlled by the clamping arm 1 to perform shearing.

[0048] Embodiment 3:

[0049] Please refer to Figures 8-10 , the present invention provides a technical solution for a dermatology clinical debridement device: a dermatology clinical debridement device, including a clamping arm 1, a clamping head 2 and a rotating shaft 3.

[0055] A sliding groove 703 is formed in the side wall of the pliers head 2. At both ends of the sliding groove 703, there are adaptation holes 704 adapted to the steel balls 702. The adaptation holes 704 are provided to limit the movement of the steel balls 702, so as to facilitate the limitation of the movement of the blade 4.

[0056] First, pass a finger through the pliers arm 1 to control the pliers head 2 to pick up and clean the impurities in the wound surface. When it is necessary to cut in the wound surface, move the sliding pile 701 to one end. The spring under the steel ball 702 at the lower end of the blade 4 will be compressed, and the steel ball 702 will be driven to leave the adaptation hole 704 at one end inside the pliers head 2. When the sliding pile 701 moves to the other end of the sliding groove 703, the steel ball 702 is inserted into the adaptation hole 704 at the other end again. At this time, release the hand, and the blade 4 at the front end of the pliers head 2 can be controlled to cut through the pliers arm 1.
