DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of an orthopedic clinical bone scraping tool provided by the utility model; Figure 2 It is a right side view of the utility model; Figure 3 It is a schematic diagram of the internal structure of the utility model; Figure 4 for Figure 3 An enlarged schematic diagram of part A is shown in FIG.

[0022] An orthopedic clinical bone scraping tool comprises: a shell 1, the shell 1 is divided into two parts, the two parts of the shell 1 are connected by a threaded extension rod 3, a through hole is opened on the surface of the shell 1, a short connecting rod passes through the middle of the through hole, a bevel gear 1 8 is fixed to the end of the short connecting rod close to the inside of the shell 1, a rotating wheel 7 is fixed to the end of the short connecting rod close to the outside of the shell 1, the bevel gear 1 8 is meshed with a bevel gear 2 9, and the bevel gear 2 9 is fixedly connected to a threaded rod 10.

[0023] The two parts of the shell 1 are connected by a threaded extension rod 3. The doctor can use the threaded extension rod 3 to adjust the overall length of the bone scraper to a length that is more suitable for the hand and convenient to operate; rotate the rotating wheel 7, and since the bevel gear 1 8 is engaged with the bevel gear 2 9, the rotation of the bevel gear 1 8 drives the bevel gear 2 9 and the threaded rod 10 to rotate at the same time.

[0024] The outer surface of the housing 1 is provided with anti-skid patterns 2, and the material of the anti-skid patterns 2 is rubber.

[0025] The rubber material can increase the friction, and the setting of the anti-skid pattern 2 can prevent the doctor from being unable to hold the bone scraper steadily due to sweating of the hands caused by intense work when operating the blade, thereby affecting the treatment effect.

[0026] A mounting plate 11 is fixedly disposed inside the housing 1 , a threaded through hole is provided at the center of the mounting plate 11 , and the threaded rod 10 is rotatably connected to the mounting plate 11 via the threaded through hole.

[0027] The threaded rod 10 is installed and positioned by a fixed mounting plate 11 . The through hole in the center of the mounting plate 11 is a threaded through hole, which makes the transmission of the threaded rod 10 more accurate.

[0028] An end output plate 14 is fixedly provided at the end of the housing 1, and an elongated through hole is opened on the end output plate 14. A blade 6 is rotatably connected to the elongated through hole via a torsion spring. A support block 15 is fixedly provided on one side of the end output plate 14 close to the inside of the housing 1, and the support block 15 is located on the back of the blade 6.

[0029] The blade 6 is rotatably connected to the long strip through hole on the end output plate 14 by a torsion spring, so that when it is in a natural state, the blade 6 opens toward the inner surface of the housing 1 on the side facing the inside of the housing 1. At this time, the back of the blade 6 is supported by the support block 15 and cannot continue to open. The blade edge of the blade 6, that is, the side facing the outside of the housing 1, is tightened, and the blade edge can be used to scrape the bone at the lesion site.

[0030] One end of the threaded rod 10 away from the bevel gear 2 9 is threadedly connected with a push block 12 , and a clamping plate 13 is fixedly provided on the lower surface of the push block 12 , and a blade 6 is clamped between the clamping plates 13 .

[0031] The rotating wheel 7 is rotated to drive the threaded rod 10 to rotate. Since the pushing block 12 is threadedly connected to the threaded rod 10, the pushing block 12 moves up and down inside the shell 1 as the threaded rod 10 rotates; when the pushing block 12 moves upward, the splint 13 moves upward accordingly, and the side of the blade 6 facing the inside of the shell 1 is tightened under the action of the splint 13, and the two blades gradually become parallel. At this time, the residual tissue scraped off the lesion site can be positioned, and when the pushing block 12 moves downward, the splint 13 moves downward accordingly, and the side of the blade 6 facing the inside of the shell 1 is opened under the action of the splint 13. At this time, the residual tissue scraped off the lesion site can be clamped and taken out to avoid affecting the healing of the patient's wound.

[0032] A switch 4 is disposed at one end of the housing 1 away from the blade 6 , and lighting bulbs 5 are disposed on both sides of the blade 6 . The switch 4 controls the start-up of the lighting bulbs 5 .

[0033] Lighting bulbs 5 are arranged on both sides of the blade 6, so that the doctor can see the specific conditions inside the wound more clearly after the blade 6 penetrates into the wound, avoiding damage to the surrounding healthy tissues.

[0034] The blade 6 is made of stainless steel, and the housing 1 is made of aluminum alloy.

[0035] The blade 6 is made of stainless steel, which is hard enough and does not rust, so as to avoid affecting the hygiene of the wound. The shell 1 is made of aluminum alloy, which is light and has high enough strength.

[0036] The working principle of an orthopedic clinical bone scraping tool provided by the utility model is as follows:

[0037] Before starting the operation, adjust the bone scraper to a length that is more suitable for the hand and convenient for operation through the threaded extension rod 3; turn on the lighting bulb 5 to facilitate the internal condition of the wound; rotate the rotating wheel to control the blade to clamp in the middle or open and close to both sides, first scrape off the tissue that needs to be removed at the lesion, then open the blade 6 to locate the residual tissue, and finally tighten the blade 6 to remove the residual tissue.

[0038] Compared with the related art, the orthopedic clinical bone scraping tool provided by the utility model has the following beneficial effects:

[0039] By rotating the wheel, the blade can be controlled to clamp in the middle or open and close to both sides, so that the residual tissue can be removed from the wound after scraping off the necrotic tissue, which is beneficial to the patient's wound healing. At the same time, this operation can be completed with one hand, without having to put down the medical device that needs to be operated in the other hand, which simplifies the doctor's operation; pressing the switch can turn on the light, making it easier for the doctor to see the specific condition inside the wound and improving work efficiency.
