Curet for surgical operation
Technical Field
The utility model particularly relates to a curet for surgical operation, which belongs to the technical field of medical instruments for operation.
Background
In surgery, particularly bone surgery, it is common practice to scrape necrotic or granulation tissue from diseased bone, and to scrape excess tissue from surgical passages. However, the variety of surgical operations is various, the operation positions are different, the operation purposes are different, and the structures of the curettes and the curettes required by the curettes are different. For example, for common bone diseases such as hyperosteogeny and lumbar intervertebral disc protrusion, it is usually necessary to remove the protrusion intervertebral disc tissue and calcified hyperplastic tissue which press nerves by surgery, then fix and further treat the bone diseases so as to achieve the purpose of eradication. To ensure the effectiveness of the procedure, it is often necessary to clean it completely and at the same time ensure safety from injuring nerves. Cursors used in surgery are generally of a single structure with a smooth cutting edge or a toothed cutting edge, which cannot meet complex surgery requirements, so that improvements to cursors used in surgery are needed.
Disclosure of Invention
The utility model provides a curet for surgical operation, which aims to solve the problem that the existing curet structure is too simple to meet the requirement of complex operation.
The technical scheme of the utility model is that: a curet for surgical operation comprises a curet rod, wherein the front end of the curet rod is fixedly connected with a curet head, a cutting edge is arranged on the curet head, the tail end of the curet rod is fixedly connected with a handle core through a pin, and a medical silica gel outer sleeve is sleeved on the handle core; the shape of the curette head is any one of spoon shape, searchlight shape and ring shape, and the included angle between the curette head and the curette rod is 180 degrees or obtuse angle.
The curette head and the curette rod are connected in a matched manner through a plug and jack structure and then welded together.
The tail end of the handle core is fixedly connected with a striking head through threads.
Optionally, the curette head is spoon-shaped, and a cutting edge is arranged at the edge of the spoon-shaped curette head.
Optionally, the curette head is in a searchlight shape, an arc groove is formed inwards on the end face of the head of the curette head, and a serrated cutting edge is arranged at the edge of the arc groove.
Optionally, the curette head is annular, and a cutting edge is arranged at the edge of the annular curette head.
Has the advantages that: the utility model can match the curette heads with various shapes such as spoon shape, searchlight shape, annular shape and the like through one curette rod, the included angle between the curette head and the curette rod is 180 degrees or obtuse angle, and the curette head is provided with a cutting edge, thereby meeting the complex operation requirements of different positions and angles; the curette head and the curette rod are connected in a matched mode through the plug and the jack structure and then welded together, the connection stability of the curette head and the curette rod is guaranteed, the processing and manufacturing cost of the curette rod can be effectively reduced by adopting the universal curette rod, the operation cost is reduced, and certain economic burden is relieved for patients.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Example one
As shown in fig. 1-5, a curette for surgical operation comprises a curette rod 2, a curette head 1 is fixedly connected to the front end of the curette rod 2, the curette head is integrally spoon-shaped, a pin hole 22 is arranged at the tail end of the curette rod 2, a handle core 3 passes through the pin hole through a pin 21 and is fixedly connected with the curette rod, a medical silica gel outer sleeve 4 is sleeved on the handle core 3, a striking head 31 is fixedly connected to the tail end of the handle core through a thread, and when necessary, a tool can be used for impacting the striking head to enhance the scraping force of the cutting edge of the curette on tissues; the included angle between the curette head and the curette rod is 180 degrees, namely the included angle is in linear arrangement, a circle of cutting edge 11 is arranged on the edge of the curette head 1, when the curette is used in an operation, the silica gel outer sleeve 4 is held by a hand and is curetted or rotated, the related tissues of the bone are curetted and cut by utilizing the sharp cutting edge 11, and the curetted tissues temporarily exist at the curette bottom and are conveniently taken out.
Example two
As shown in fig. 6-10, in this embodiment, the curette head 13 and the curette rod are connected in a bent manner, the included angle is an obtuse angle, a socket 12 is provided at one end of the curette head, the socket 12 is welded with a plug (not shown) on the curette rod after being connected in a matching manner, the head end face at the other end of the curette head is in a searchlight shape, a cambered groove 132 is provided inwards at the head end face of the curette head, and a serrated cutting edge 131 is provided at the edge of the cambered groove. The other structures are the same as those of the first embodiment. In the embodiment, the curette head and the curette rod are bent at a certain obtuse angle, so that the operation sight is not influenced, the operation is convenient, harder bone spurs and the like can be cut and scraped by the serrated cutting edge, and the cut scraps can be temporarily stored by the cambered groove conveniently.
EXAMPLE III
As shown in fig. 11-12, in this embodiment, an annular spatula head 14 is adopted, the included angle between the annular spatula head and the spatula rod is 180 degrees, the upper and lower parts of the annular spatula head 14 are symmetrically provided with cutting edge rings 141, and the rest parts are the same as those of the first embodiment and the second embodiment. The double-cutting-edge annular curette head can improve the tissue curettage efficiency in the operation.

As shown in fig. 13-14, in this embodiment, a ring-shaped spatula head 15 is adopted, the ring-shaped spatula head 15 and the spatula rod are connected in a bending way, the included angle is an obtuse angle, a plug 16 is arranged at one end of the ring-shaped spatula head, and the plug 16 is connected with a plug hole (not shown) on the spatula rod in a matching way and then welded together. The other parts are the same as the first embodiment. The annular curette head 15 is in an annular triangle shape as a whole, and the head part of the annular curette head is provided with a parallel cutting edge 151, so that various redundant or pathological tissues can be conveniently curetted in the operation.
The utility model provides a multiple embodiment both can the exclusive use in the operation of difference, also can mutually support the use, accomplishes some more complicated operation operations jointly, for example in the operation treatment of intervertebral disc protrusion, both can effectively strike off unnecessary pathological change tissue totally through this curette, can not injure nerve again to improve operation efficiency.
