[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention solves the problem of excessive use of disinfectant due to uneven manual application by arranging the coordination of structures such as a rotating disk and a ball. The motor is started to rotate the first gear, and the rotation of the first gear drives the second gear meshing with it to rotate. The rotation of the second gear drives the first bevel gear fixedly connected with it to rotate. The rotation of the first bevel gear drives the second bevel gear meshing with it to rotate. The rotation of the second bevel gear drives the rotating disk to rotate. The rotation of the rotating disk can drive the ball with the surface soaked with disinfectant to rotate under the contact and compression of the skin. The disinfectant is applied to the skin after hair removal through the ball for disinfection. Because the diameter of the rotating disk is equal to the length of the blade and the slider, the position where the hair is removed can be evenly coated with disinfectant. At the same time, the provision of a spring can prevent the disinfectant from overflowing from the device when the device is not in use and from overflowing excessively when it is in use, resulting in a waste of disinfectant.

[0018] The present invention facilitates effective disinfection of the skin groove by the disinfectant by setting the coordination of structures such as the third gear and the smear pad. The rotation of the first gear drives the third gear meshing therewith to rotate, and the rotation of the third gear drives the rotating shaft to make eccentric movement with the third gear as the center, thereby driving the slider to move through the connecting rod, and sliding inside the slide groove under the limit of the limit block to generate vibration, so that the vibration can be transmitted to the skin coated with the disinfectant through the smear pad, which can promote the disinfectant molecules to penetrate into the skin pores and hair follicles more evenly and deeply, improve the disinfection effect, and produce a slight massage effect on the skin, which can relieve the skin tension or discomfort that may be caused during shaving, improve the patient's skin preparation experience, and at the same time help to accelerate the loss of disinfectant on the skin surface, shorten the waiting time for drying, and improve the efficiency of surgical skin preparation;

[0019] The present invention facilitates hair removal on the skin by providing cooperation between structures such as a cleaning block and a blade, so that the main body shell moves in a direction close to the guard blade, so that the guard blade inside the fixing plate removes hair on the skin and is pushed forward by the blade. However, when passing through the irregular surface of the skin, some broken hair will be left in place from the gap between the blade and the guard blade. The cleaning block can take away the remaining hair through the inclined groove, thereby avoiding the situation where the remaining hair affects subsequent disinfection and application. At the same time, the functions of hair removal, application of disinfectant and more uniform application of disinfectant are integrated into a set of skin preparation devices, thereby reducing the conversion time during the skin preparation process, and there is no need to use a razor separately and then apply disinfectant, which greatly saves the operation preparation time and is convenient for medical staff to operate.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0031] like Figures 1 to 9 As shown, the present invention provides a neurosurgery skin preparation device, comprising a disinfection mechanism 1, which is arranged inside a main body mechanism 3, and inside the main body mechanism 3 are provided with a smearing mechanism 2 and a scraper mechanism 4, and the scraper mechanism 4 is located on a side of the disinfection mechanism 1 away from the smearing mechanism 2;

[0033] A plurality of balls 109 are evenly distributed inside the turntable 106 , and the balls 109 correspond to a plurality of springs 110 respectively. The balls 109 are elastically connected to the top of the turntable 106 through the springs 110 , and the side of the balls 109 away from the springs 110 passes through the inner wall of the turntable 106 and extends to the bottom of the turntable 106 .

[0034] The above solution is adopted: the cooperation of the structures such as the turntable and the ball bearing is provided, so as to solve the problem that the manual application often causes excessive use of disinfectant due to unevenness. The motor is started to rotate the first gear, and the rotation of the first gear drives the second gear meshing with it to rotate. The rotation of the second gear drives the first bevel gear fixedly connected with it to rotate. The rotation of the first bevel gear drives the second bevel gear meshing with it to rotate. The rotation of the second bevel gear drives the turntable to rotate. The rotation of the turntable can drive the ball bearing with the surface soaked with disinfectant to rotate under the contact and compression of the skin. The disinfectant is applied to the skin after the hair is removed through the ball bearing for disinfection. Because the diameter of the turntable 106 is equal to the length of the blade 403 and the slider 204, the position where the hair is removed can be evenly coated with disinfectant. At the same time, the spring 110 is provided to prevent the disinfectant from overflowing from the device when the device is not in use and excessively overflowing when it is in use, resulting in a waste of disinfectant.

[0035] like Figures 2 to 6 As shown, the smearing mechanism 2 includes a third gear 201, a rotating shaft 202 is fixedly connected to the third gear 201, a connecting rod 203 is rotatably connected to the rotating shaft 202, a slider 204 is hinged at one end of the connecting rod 203 away from the rotating shaft 202, a first limiting groove 205 is provided on the side of the slider 204, and a smearing pad 206 is fixedly connected to the bottom of the slider 204.

[0036] The rotating shaft 202 is located at an eccentric position of the third gear 201, the side of the first gear 102 away from the first gear 102 is meshed with the third gear 201, the connecting rod 203 is located away from the rotating shaft 202 and is located on the side of the third gear 201 away from the first gear 102, the connecting rod 203 is located above the turntable 106, the slider 204 is located on the side of the turntable 106, and the size of the first gear 102 is larger than that of the third gear 201.

[0037] The main body mechanism 3 includes a main shell 301, a handle 302 is fixedly connected to the top of the main shell 301, a second limiting groove 303 is provided at the bottom of the main shell 301, an infusion groove 306 is provided on the inner wall of the second limiting groove 303, a slide groove 304 is provided at the bottom of the main shell 301, two limiting blocks 305 are fixedly connected to the inner wall of the slide groove 304, a cleaning block 307 is fixedly connected to the bottom of the main shell 301, an inclined groove 308 is provided on the cleaning block 307, and a liquid storage bottle 309 is threadedly connected to the top of the main shell 301.

[0038] The above scheme is adopted: the smear pad 206 and the cleaning block 307 are both made of elastic materials, and the first gear 102 with a larger size drives the third gear 201 with a smaller size to rotate, which will make the vibration frequency of the slider 204 greater than the rotation speed of the turntable 106. By setting the third gear 201 and the smear pad 206 and other structures to cooperate, it is convenient for the disinfectant to effectively disinfect the skin groove. The rotation of the first gear 102 will drive the third gear 201 meshing with it to rotate, and the rotation of the third gear 201 will drive the rotating shaft 202 to make an eccentric movement with the third gear 201 as the center, so that through the connecting rod 203 drives the slider 204 to move, and slides inside the slide groove 304 under the limit of the limit block 305, generating vibration, so that the vibration can be transmitted to the skin coated with the disinfectant through the application pad 206, which can promote the disinfectant molecules to penetrate into the skin pores and hair follicles more evenly and deeply, improve the disinfection effect, and produce a micro-massage effect on the skin, which can relieve the skin tension or discomfort that may be caused during shaving, enhance the patient's skin preparation experience, and at the same time help to accelerate the loss of disinfectant on the skin surface, shorten the waiting time for drying, and improve the efficiency of surgical skin preparation.

[0039] like Figure 3 , Figure 5 and Fig. 9 As shown, the bottom of the liquid storage bottle 309 passes through the top of the main shell 301 and extends to the interior of the smear pad 206. The slide groove 304 is located on the side of the second limiting groove 303 away from the cleaning block 307. The inclined groove 308 is located on the side of the cleaning block 307 and away from the second limiting groove 303. The appearance of the cleaning block 307 is a "V" shape. The motor 101 is fixedly connected to the inner wall of the main shell 301, the first gear 102 is rotatably connected to the inner wall of the main shell 301, the turntable 106 is rotatably connected to the inner wall of the second limiting groove 303 through the leakage hole 107, and the infusion groove 306 is located above the turntable 106.

[0040] The slider 204 is slidably connected to the slide groove 304 bracket, the size of the first limit groove 205 is adapted to the size of the limit block 305, the first limit groove 205 and the limit block 305 are clamped together, the smear pad 206 passes through the inner wall of the slide groove 304 and extends to the bottom of the main shell 301, and the ball 109 is located between the cleaning block 307 and the smear pad 206.

[0041] The scraper mechanism 4 includes a fixed plate 401, a guard blade 402 is fixedly connected to the fixed plate 401, a blade 403 is fixedly connected between the fixed plate 401 and the guard blade 402, mounting plates 404 are fixedly connected to both sides of the fixed plate 401, bolts 405 are threadedly connected to the mounting plate 404, the mounting plate 404 is fixedly connected to the top of the main shell 301 through the bolts 405, the fixed plate 401 passes through the top of the main shell 301 and extends to the bottom of the main shell 301, and the fixed plate 401 is located on the side of the blade 403 away from the cleaning block 307.

[0042] The above scheme is adopted: by setting the cooperation of the cleaning block and the blade and other structures, it is convenient to remove hair from the skin, so that the main body shell moves in the direction close to the guard blade, so that the guard blade inside the fixed plate removes the hair on the skin and is pushed forward by the blade 403. However, when passing through the irregular surface of the skin, some broken hair will be left in the gap between the blade 403 and the guard blade 402. The cleaning block 307 can take away the remaining hair through the inclined groove 308, avoiding the situation where the remaining hair affects the subsequent disinfection and application. At the same time, the functions of hair removal, application of disinfectant and more uniform application of disinfectant are integrated into a set of skin preparation devices, reducing the conversion time during the skin preparation process, and there is no need to use the razor separately and then apply the disinfectant, which greatly saves the operation preparation time and is convenient for medical staff to operate.

[0043] The working principle and use process of the present invention are as follows: during the preoperative skin preparation for neurosurgery, the liquid storage bottle 309 is first removed and disinfectant is injected into the liquid storage bottle 309, and the liquid storage bottle 309 is installed inside the main body shell 301, so that the disinfectant enters the inside of the turntable 106 through the infusion tank 306. Then, the medical staff needs to disinfect the device and then hold the handle 302 to move the side of the main body shell 301 close to the guard blade 402 to the skin preparation position, so that the guard blade 402 is against the skin, and the main body shell 301 is moved in the direction close to the guard blade 402, so that the guard blade 402 inside the fixing plate 401 removes the hair on the skin and is pushed forward by the blade 403. However, because some of the broken hair will be left in the gap between the blade 403 and the guard blade 402 when passing through the irregular surface of the skin, and the cleaning block 307 is provided to take away the remaining hair through the inclined groove 308;

[0044] Then, the motor 101 is started to rotate the first gear 102. The rotation of the first gear 102 drives the second gear 103 meshing therewith to rotate. The rotation of the second gear 103 drives the first bevel gear 104 fixedly connected thereto to rotate. The rotation of the first bevel gear 104 drives the second bevel gear 105 meshing therewith to rotate. The rotation of the second bevel gear 105 drives the rotating disk 106 to rotate. The rotation of the rotating disk 106 can drive the ball 109 with the surface soaked with disinfectant to rotate under the contact and compression of the skin, so that the disinfectant is evenly applied to the skin after hair removal for disinfection through the ball 109.

[0045] At the same time, the rotation of the first gear 102 will drive the third gear 201 meshing therewith to rotate, and the rotation of the third gear 201 will drive the rotating shaft 202 to make an eccentric movement with the third gear 201 as the center, thereby driving the slider 204 to move through the connecting rod 203, and sliding inside the slide groove 304 under the limit of the limit block 305, generating vibration, so that the vibration can be transmitted to the skin coated with the disinfectant through the application pad 206, which can promote the disinfectant molecules to penetrate into the skin pores and hair follicles more evenly and deeply, improve the disinfection effect, and produce a slight massage effect on the skin, which can relieve the skin tension or discomfort that may be caused during shaving, and improve the patient's skin preparation experience;

[0046] After the skin preparation is completed, it is only necessary to rotate the bolt 405 to release the fixing of the mounting plate 404 and the main housing 301, remove and replace the scraper mechanism 4, remove the liquid storage bottle 309, and finally disinfect the inside of the device.
