[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] like Figures 1 to 3 As shown, an embodiment of the present application provides a scraper, including: a clamp body 1, including a first clamp arm 11 and a second clamp arm 12, the first clamp arm 11 and the second clamp arm 12 are hinged; a scraper assembly 2, including a first scraper head 21 and a second scraper head 22, the first scraper head 21 is located at the end of the first clamp arm 11, and the second scraper head 22 is located at the end of the second clamp arm 12, the first scraper head 21 and the second scraper head 22 both include a connected scraper shell 23 and a clamp plate 24, the clamp plate 24 of the first scraper head 21 and the clamp plate 24 of the second scraper head 22 are arranged opposite to each other, and the first clamp arm 11 and the second clamp arm 12 drive the first clamp plate 24 and the second clamp plate 24 to move closer to or away from each other.

[0027] When the curette is used for orthopedic surgery, the curette housing 23 of the first curette head 21 and the curette housing 23 of the second curette head 22 can scrape the hematoma, and after the hematoma is scraped, the scraped hematoma and other tissues can be clamped and removed through the two clamping plates 24. The curette of this embodiment can scrape the hematoma and remove the hematoma tissue, etc., and integrates the functions of scraping and clamping. There is no need to replace surgical instruments during the operation, which saves operation time and reduces operation risks.

[0028] In the prior art, a curette with a suction device is used to remove hematoma during orthopedic surgery, which can easily cause bone fragments to be sucked into the lumen of the suction device, causing blockage and affecting the progress of the surgery. In this embodiment, there is no need to worry about lumen blockage during the surgery, and the progress of the surgery will not be affected.

[0029] The first forceps arm 11 has a first forceps beak 110, the second forceps arm 12 has a second forceps beak 120, the clamp plate 24 of the first scraper head 21 is connected to the first forceps beak 110, and the clamp plate 24 of the second scraper head 22 is connected to the second forceps beak 120. Preferably, the first clamp plate 24 of the first scraper head 21 is formed by extending the first forceps beak 110, and the second clamp plate 24 of the second scraper head 22 is formed by extending the second forceps beak 120.

[0030] In this embodiment, the thickness of the clamp plate 24 is the same as the thickness of the scraper housing 23. In one embodiment, the upper surface of the clamp plate 24 is flush with the upper surface of the scraper housing 23. In another embodiment, the upper surface of the clamp plate 24 can also be lower than the upper surface of the scraper housing 23.

[0031] The scraper shell 23 is a quarter sphere structure, the interior of the sphere structure is a hollow structure, and the sphere structure has an open portion 25. When the first scraper head 21 and the clamp plate 24 of the second scraper head 22 are attached, the two scraper shells 23 form a hemispherical structure, which is convenient for scraping hematoma.

[0032] In order to realize the articulation of the first clamp arm 11 and the second clamp arm 12, the first clamp arm 11 is provided with a first hinged portion 111 in this embodiment, and the first hinged portion 111 is connected to the first clamp beak 110. The second clamp arm 12 is provided with a second hinged portion 121, and the second hinged portion 121 is connected to the second clamp beak 120. The first clamp arm 11 and the second clamp arm 12 are articulated through the first hinged portion 111 and the second hinged portion 121. In one embodiment, the first hinged portion 111 and the second hinged portion 121 can be articulated through the articulation shaft 13. The first hinged portion 111 is placed in the middle of the first clamp arm 11, and the second hinged portion 121 is placed in the middle of the second clamp arm 12; or the first hinged portion 111 is arranged close to the first clamp beak 110, and the second hinged portion 121 is arranged close to the second clamp beak 120.

[0033] The first clamp arm 11 also has a first clamp rod 112 and a first clamp ring 113, and the first hinged portion 111 is connected to the first clamp ring 113 via the first clamp rod 112. The second clamp arm 12 also has a second clamp rod 122 and a second clamp ring 123, and the second hinged portion 121 is connected to the second clamp ring 123 via the second clamp rod 122. When the curette is in use, fingers can be placed in the first clamp ring 113 and the second clamp ring 123 respectively, and then the first clamp ring 113 and the second clamp ring 123 drive the two curette housings 23 to separate or approach.

[0034] The first clamp arm 11 and the second clamp arm 12 of this embodiment can be locked. In order to achieve the locking of the first clamp arm 11 and the second clamp arm 12, a first locking component 14 is provided on one end of the first clamp rod 112 close to the first clamp ring 113, and a second locking component 15 is provided on one end of the second clamp rod 122 close to the second clamp ring 123. The first clamp arm 11 and the second clamp arm 12 are locked by the first locking component 14 and the second locking component 15.

[0035] Specifically, the first locking assembly 14 includes a first locking rod 141 and a first recessed portion 142, and the second locking assembly 15 includes a second locking rod 151 and a second recessed portion 152. The first locking rod 141 cooperates with the second recessed portion 152, and the second locking rod 141 cooperates with the second recessed portion 152. When the first locking rod 141 is placed in the second recessed portion 152, and the second locking rod 151 is placed in the first recessed portion 142, the first clamp arm 11 and the second clamp arm 12 can be locked.

[0036] When the first clamp arm 11 and the second clamp arm 12 are locked by the first locking assembly 14 and the second locking assembly 15, the two clamp plates 24 are fitted together, and the two first scraper heads 21 and the second scraper head 22 form a hemispherical structure, and a scraping operation of a hematoma or the like can be performed. When the locking state of the first clamp arm 11 and the second clamp arm 12 is released, the scraper can be used as a hemostatic forceps to clamp a hematoma or the like.

[0037] In one embodiment, the first clamp arm 11 can be integrally formed, and the second clamp arm 12 can also be integrally formed. In another embodiment, the first clamp arm 11 and the first curette head 21 can be integrally formed, and the second clamp arm 12 and the second curette head 22 can also be integrally formed.
