Detailed Description
The present application is described in further detail below with reference to the attached drawings.
The first embodiment is as follows:
referring to fig. 1 and 2, the present application provides a bone file, including an integrally formed file head 1 and a file rod 2, the file head 1 is bent and extended toward one side of the file rod 2, the file head 1 is arc-shaped, and the file head 1 is convex toward a direction away from the file head 1, the concave surface of the file head 1 forms a working surface 11, the working surface 11 is arc-shaped, and a plurality of file striations 3 are formed on the working surface 11, the file striations 3 extend in a direction perpendicular to the extending direction of the working surface 11, and the plurality of file striations 3 are uniformly distributed along the extending direction of the working surface 11, i.e., the extending direction of the file head 1; in order to hold and move the file rod 2, a handle 5 is coaxially fixed at one end of the file rod 2, which is far away from the file head 1.
The surface of the file head 1 is not well fitted to the edge of the bone hole after the file head 1 in the related art is moved to the edge of the bone hole, and the file head 1 and the edge of the bone hole cannot be continuously rubbed back and forth even though the file rod 2 is reciprocally moved, so that it is necessary to perform a secondary opening to the opposite side of the opening of the skin surface so that the file head 1 can be fitted to the edge of the bone hole to the opposite side.
Referring to fig. 3, when it is desired to file an edge of an end of a bone hole at a position away from the opening of the skin surface, the rasp head 1 and the rasp rod 2 are inserted from the opening of the skin surface, and the rasp head 1 is extended toward the end of the bone hole at the position away from the opening of the skin surface by the handle 5 and the rasp rod 2 until the rasp head 1 is moved to the edge to be filed; meanwhile, the rasp head 1 faces to the side away from the axis of the bone hole, namely, the rasp head 1 faces to the edge of the bone hole, and the rasp head 1 extends to one side of the rasp rod 2, so that the working surface 11 can be lapped at the edge of the bone hole; the file rod 2 is utilized to ensure that the file head 1 reciprocates at one end of the bone hole along the direction parallel to the axis of the bone hole, and the working surface 11 further rubs with the edge of the bone hole in a reciprocating way to file the edge of the bone hole; this process need not carry out the secondary opening in the relative one side of human skin opening part, is convenient for carry out the file to bone hole both ends edge, has prevented that the file in-process from need causing the secondary injury to the patient.
Further, referring to fig. 2 and 3, in order to file the edge of the bone hole more sufficiently and effectively by the rasp 1, the rasp 3 is a trapezoidal rasp 3, and thus the contact area between the rasp 3 and the edge of the bone hole, i.e., the rasp area of the bone hole, is increased compared to the dotted rasp 3 in the related art, so that the rasp 1 can effectively file the edge of the bone hole and improve the rasp efficiency; in addition, the chip grooves 4 capable of containing bone chips or bone residues are formed between the adjacent rasps 3, in the filing process, the bone chips or the bone residues and the like fall off or are brought into the space between the adjacent rasps 3, namely the inside of the chip grooves 4, after filing is completed, the file head 1 is taken out from the inside of the bone hole, the file head 1 further brings out the bone chips or the bone residues in the chip grooves 4, the situation that the bone chips or the bone residues enter a bone channel or a human tissue is effectively reduced, and the bone chips or the bone residues are convenient to clean.
Furthermore, referring to fig. 2 and 3, an included angle between the surface of the file 3 away from the file rod 2 and the working surface 11, that is, an included angle between the waist of the file 3 away from the file rod 2 and the working surface 11, is smaller than an included angle between the surface of the file 3 close to the file rod 2 and the working surface 11, that is, an included angle between the waist of the file 3 close to the file rod 2 and the working surface 11, and further a length of the surface of the file 3 close to the file rod 2 along the extending direction of the file head 1 is smaller than a length of the surface of the file 3 away from the file rod 2 along the extending direction of the file head 1; thus, when the surface of the rasp 3 close to the rasp rod 2 passes through the edge of the bone hole, the surface of the rasp 3 is lapped on the edge of the bone hole to rasp the edge of the bone hole, and further the rasp can be abutted and rubbed with the edge of the bone hole in a larger area, so that a better rasp effect is achieved; in addition, the contained angle between the surface that file pole 2 deviates from file pole 2 and working face 11 is less, and then satisfies the intensity requirement of file line 3, improves the life of file line 3.
Referring to fig. 1, the diameter of the file rod 2 is gradually reduced along the direction from the handle 5 to the file head 1, so that the diameter of the rod section of the file rod 2 which is about to enter the bone hole is reduced under the condition of ensuring the connection strength of the connection part of the file rod 2 and the handle 5, so that the file rod 2 can be more accurately and conveniently inserted into the bone hole, and the weight of the whole bone file is reduced; in addition, two holding surfaces 51 are respectively processed on two sides of the handle 5, the holding surfaces 51 are plane surfaces and extend along the direction parallel to the axis of the handle 5, and the two holding surfaces 51 are respectively formed on one side of the handle 5 close to and far away from the bending direction of the filing head 1; in the process of pushing and pulling the file rod 2, the fingers of the doctor can be respectively attached to the two holding surfaces 51, the two holding surfaces 51 are respectively formed on one side of the handle 5 close to and departing from the bending direction of the file head 1, and the operation of the doctor is more convenient due to the design.
Referring to fig. 2 and 3, in order to reduce the sharp part of the file head 1 and prevent the sharp part of the file head 1 from damaging bones or soft tissues, a rounded corner is processed at the edge of the surface of the file head 1 departing from the working surface 11, and one end of the file head 1 departing from the file rod 2 is arc-shaped.
Example two:
referring to fig. 4 and 5, the present embodiment is different from the first embodiment in that the shape of the file head 1 is different, in the present embodiment, the file head 1 is a rectangular parallelepiped strip-shaped file head 1, and one end of the file head 1 away from the file rod 2 is circular arc-shaped, and the working surface 11 is a plane extending along the extending direction of the file head 1.
To sum up, the application process of this application is: when the edge of one end of the bone hole, which is away from the skin surface opening position, needs to be filed, the rasp head 1 extends towards one end of the bone hole, which is away from the skin surface opening position, through the handle 5 and the rasp rod 2, and the rasp head 1 faces the edge of the bone hole until the working surface 11 is lapped at the edge of the bone hole; the file rod 2 is utilized to ensure that the file head 1 reciprocates at one end of the bone hole along the direction parallel to the axis of the bone hole, and the working surface 11 further rubs with the edge of the bone hole in a reciprocating way to file the edge of the bone hole; this process need not carry out the secondary opening in the relative one side of human skin opening part, is convenient for carry out the file to bone hole both ends edge, has prevented that the file in-process from need causing the secondary injury to the patient.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
