Description

Technical Field

[0001] The invention belongs to the technical field of medical tools, and in particular relates to a burn wound surface scab abrader. Background Art

[0002] Currently, the main cause of death from large-area burns is still systemic infection. The main source of bacteria is the wound surface. The eschar is necrotic tissue, which is a good place for bacteria to reproduce, and therefore poses the greatest threat to the wounded.

[0003] Deep burns include second-degree burns and third-degree burns. The burn area has a layer of leather-like coagulated necrosis, which is called eschar. The eschar is inelastic and covers the wound surface, which can limit the outward expansion of local edema. The annular eschar tightly surrounds the patient's limbs and trunk, and the gradual edema of the tissue under the eschar. These two forces act like a tourniquet to continuously and forcefully compress the deep tissues, causing compression syndrome. For example, in the limbs, compression of deep blood vessels, nerves, muscles and other tissues can cause blood circulation disorders and cause fascial syndrome, which manifests as ischemic necrosis of the compressed local muscle groups, and even necrosis of the finger (toe) tips. In severe cases, it can lead to necrosis of the entire limb; in the neck and chest, compression of the trachea or thorax can seriously affect breathing, leading to dyspnea and even respiratory failure. Eschar is a kind of coagulative necrosis, which is an excellent environment for bacterial growth and reproduction. In addition, eschar will dissolve and separate after a certain period of time, and various corruption products can be released in the process, which can cause infection due to bacterial action, or poisoning after toxin absorption. In mild cases, a series of poisoning symptoms will appear, and in severe cases, death can occur. Therefore, appropriate treatment measures must be taken for eschar to prevent the occurrence of the above complications.

[0004] At present, excisional debridement of surgical infected wounds is the main method for removing necrotic tissue from burn wounds. Surgical debridement mainly includes escharectomy, eschar scraping, eschar grinding, etc. Among them, eschar grinding is to use an eschar grinding device to remove the surface necrotic tissue structure layer by layer through mechanical friction until the wound surface shows extensive pinpoint bleeding or bright red congestion. The existing eschar grinding device mainly drives the grinding wheel to rotate through a motor, which is easy to cause secondary damage to the wound surface and abrasion to the skin during eschar removal.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 8 As shown;

A positioning groove 18 is opened inside the pressure rod 17, and a positioning seat 19 is arranged inside the positioning groove 18. The positioning seat 19 is slidably connected with the pressure rod 17 through the positioning groove 18. The positioning cylinder 110 is rotatably connected inside the positioning seat 19.

[0046] In this embodiment: when the positioning shell 11 is attached to the leg surface, the sponge wheel 32 will be tightly attached to the leg surface due to the elastic potential energy of the spring B34. When the positioning shell 11 moves, the sponge wheel 32 will rotate inside the positioning ring 33 due to the friction force. The sponge wheel 32 will absorb the pus inside the wound after cleaning the scar scab, thereby cleaning the pus inside the wound.

[0047] Going further:

[0048] In an optional embodiment, a water pump 35 is installed on the surface of the positioning shell 11 through a mounting seat C, a water storage shell 36 is provided inside the positioning shell 11, an output end of the water pump 35 passes through the interior of the positioning shell 11 and is interconnected with the water storage shell 36, and a plurality of atomization holes 37 are provided on the surface of the water storage shell 36.

The saline will be atomized according to the size of the inner diameter of the atomization hole 37, making the spraying more uniform, moistening the scar scab, and facilitating subsequent cleaning.

[0050] The working principle and use process of the present invention are as follows: when using the scab grater, the positioning shell 11 is placed in the cleaning position, the electric push rod 112 is connected to the external power supply and then started, the electric push rod 112 will apply force to the limit rod 111, and will indirectly make the pressure rod 17 slide inside the slide groove 115 until the scab grating shovel 13 contacts the scar scab, and then the motor 12 is connected to the external power supply and then started, the output shaft of the motor 12 will drive the bidirectional screw 15 to rotate, the rotation of the bidirectional screw 15 will drive the scab grating shovel 13 to move back and forth through the connecting plate A14, the scab grating shovel 13 will use its own repeated movement to scoop up the scar scab, when the scab grating shovel 13 moves back and forth, the friction force drives the pressure rod 17 to move, the movement of the pressure rod 17 will make the positioning seat 19 slide inside the positioning groove 18, reducing the pressure on the scab grating shovel 13. The lateral resistance of the output shaft of the electric push rod 112 increases the service life of the electric push rod 112. Because the leg is not a regular circle, when the scab shovel 13 is close to the leg surface, the scab shovel 13 will stick to the leg surface and form a certain angle of inclination. The positioning seat 19 will be driven to rotate inside the positioning cylinder 110, so that the scab shovel 13 can be close to the leg surface, making the scab rubbing more thorough. When the scab rubbing shovel 13 moves back and forth, the rubber pad 114 will rub the remaining scars and scabs to prevent the residual scars and scabs from causing incomplete treatment and repeated cleaning. When the scars and scabs need to be cleaned, the two splints 24 are placed on both sides of the leg, and then the two splints 24 are squeezed toward the center. The two connecting plates B21 will slide toward the center on the surface of the positioning shell 11. When the two splints When the plate 24 moves toward the center, the positioning block B23 and the positioning block A22 will move alternately, and the ratchet plate B210 and the ratchet plate A26 will fit and rub against each other. Due to the characteristics of the shapes of the ratchet plates A26 and B210, the spring A212 will be repeatedly squeezed until the two splints 24 clamp the legs, and the ratchet plate B210 will mesh with the ratchet plate A26, thereby realizing the positioning of the positioning shell 11. When it is necessary to clean the scar scab, force is applied to the positioning shell 11 to make the connecting plate B21 slide on the surfaces of the positioning block A22 and the positioning block B23, thereby realizing the axial positioning of the positioning shell 11 when cleaning the scar scab, so that the positioning shell 11 will not shake when cleaning the scar scab. When it is necessary to release the splint 24, force is applied to the knob 28 to rotate it, and the elliptical plate 27 will release the limit on the two ratchet plates A26, and the tension spring 211 will pull the two ratchet plates A26 away from the ratchet plate B29 due to the elastic potential energy, indirectly loosening the limit on the two splints 24, so that the positioning shell 11 can be removed. When the positioning shell 11 is attached to the leg surface, the sponge wheel 32 will be tightly attached to the leg surface due to the elastic potential energy of the spring B34. When the positioning shell 11 moves, the sponge wheel 32 will rotate inside the positioning ring 33 due to the friction force. The sponge wheel 32 will absorb the pus inside the wound after cleaning the scar scab, thereby cleaning the pus inside the wound. Before cleaning the scar scab, connect the water pump 35 to an external power supply and then start it. The water pump 35 will inject external saline into the interior of the water storage shell 36, and the saline will be sprayed out through the atomization hole 37.The size of the inner diameter of the atomizing hole 37 is used to atomize the physiological saline solution, so that the spraying is more uniform, which moistens the scar and facilitates subsequent cleaning.
