Description
Technical field
This utility model relates to spinal operation medical apparatus and instruments, particularly relates to a kind of scraper for clearing up terminal plate of vertebral body in spinal column.
Background technology
At present, doctor after removal of disc, needs, with the remnant tissue's (cartilage etc.) on scraper process terminal plate of vertebral body, to reach better syncretizing effect with this in operation.As shown in Figures 1 and 2, after intervertebral inserted by existing similar monolithic scraper 9, because it is lamellar, supporting role effectively can not be played to adjacent vertebral bodies 5 when rotating and clearing up terminal plate of vertebral body 51, thus cause strutting highly unstable, easily cause situations such as striking off dark, injury terminal plate of vertebral body 51.Based on the problems referred to above, need a kind of scraper effectively can clearing up remnant tissue on terminal plate of vertebral body while avoiding injuring terminal plate of vertebral body.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of scraper for spinal operation, and it is easy to operate, working stability, effectively can clear up the tissue on terminal plate of vertebral body.
In order to solve the problems of the technologies described above, this utility model adopts following technical scheme: a kind of scraper for spinal operation, comprise cutter head, knife bar and handle of a knife, cutter head is installed in the front end of described knife bar, handle of a knife is installed in rear end, the outer surface of described cutter head offers the elongated slot that at least one extends along scraper length direction, the part that the left and right sides of described elongated slot inwall and cutter head outer wall intersect forms two blades.
Preferably, described cutter head is the string configuration arranged along scraper length direction.
Preferably, described elongated slot has two, and the part that the left and right sides of elongated slot inwall and cutter head outer wall intersect forms two blades, two relative scraper axisymmetrical of elongated slot respectively.
Preferably, the bottom land of described elongated slot offers through hole.
As mentioned above, this utility model is used for the scraper of spinal operation, has following beneficial effect:
This utility model is rectangular structure, effectively can strut adjacent vertebral bodies in use, and stablizes its height.
This utility model is provided with multiple blade, can accomplish to strike off thorough noresidue when clearing up terminal plate of vertebral body, and can not scratch terminal plate of vertebral body.In addition, handle of the present utility model singlehanded or both hands can grip simultaneously or holds operation from different perspectives, uses comfort and convenient.

Detailed description of the invention
The structure that Figure of description illustrates, ratio, size etc., content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of this utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that this utility model can produce and the object that can reach, all should still drop in scope that technology contents that this utility model discloses can contain.Simultaneously, quote in this description as " on ", D score, "front", "rear", the term such as " centre ", also only for ease of understanding of describing, and be not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of this utility model.
As Figure 3-Figure 4, a kind of scraper for spinal operation of this utility model, comprise cutter head 1, knife bar 2 and handle of a knife 3, cutter head 1 is installed in the front end of described knife bar 2, handle of a knife 3 is installed in rear end, the outer surface of described cutter head 1 offers the elongated slot 11 that at least one extends along scraper length direction, the part that the left and right sides of described elongated slot 11 inwall and cutter head 1 outer wall intersect forms two blades 4.Described blade 4 can strike off cleaning to the tissue on terminal plate of vertebral body.
In order to the convenience used, described cutter head 1 is the string configuration arranged along scraper length direction, specifically in rectangular structure.
In the present embodiment, described elongated slot 11 has two, and the part that the left and right sides of elongated slot 11 inwall and cutter head 1 outer wall intersect forms two blades, 4, two elongated slots 11 scraper axisymmetrical relatively respectively.The blade 4 formed on four blades, 4, two elongated slots 11 by two elongated slots 11 can be cleared up adjacent vertebral bodies soleplate simultaneously, thus effectively increases work efficiency.
When reality uses this scraper, if need organizing of cleaning more, limit is then needed to clear up, while take out the cleaned tissue got off from intervertebral, scraper will be caused so repeatedly to insert at intervertebral-extract, this not only adds operation time, and also have certain influence to vertebral body, therefore in the present embodiment, the bottom land of described elongated slot 11 offers through hole 12, namely two elongated slots 11 share a through hole 12, described through hole 12 can store the tissue cleared up by scraper temporarily, scraper is taken out again after described through hole 12 fills tissue, therefore scraper is not needed repeatedly to insert at intervertebral-extract.
Composition graphs 3-Fig. 8, work process of the present utility model mainly comprises:
(1) as shown in Figure 5, insert between vertebral body 5 by the cutter head 1 of scraper, during insertion, two elongated slots 11 are not towards terminal plate of vertebral body 41, and when avoiding inserting, its hetero-organization of blade 4 pairs of vertebral bodys 5 damages.
(2) after scraper insertion puts in place, as shown in Figure 6, rotation scraper struts adjacent vertebral body 5 makes the ligament of this sections pull open, elongated slot 11 on scraper after rotation is respectively towards a terminal plate of vertebral body 51, two blades 4 of each elongated slot 11 the right and left with contact with terminal plate of vertebral body 51 respectively, namely as shown in Figure 7.
(3) scraper is rotated, four blades 4 are cleared up the terminal plate of vertebral body 51 on two vertebral bodys 5 simultaneously, because be that two blades 4 are cleared up a terminal plate of vertebral body 51, therefore the rotation amplitude of scraper is without the need to too large, intervertebral height (distance between vertebral body) reduces limited, can not allow too much the scraping on terminal plate of vertebral body 51 of blade 4, and scraper rotates and also effectively ensure that intervertebral height by a small margin.Can be stored in the through hole 12 of cutter head 1 by the tissue that blade 4 is cleared up, taking-up scraper after through hole 12 is filled and will clear up tissue collecting process.
(4) action of step (3) is repeated, until cleaned out by terminal plate of vertebral body 51 or meet operation needs.
(5) taken out by scraper, terminal plate of vertebral body 51 has been cleared up, and carries out other operation techniques.
In sum, this utility model is used for the scraper of spinal operation, can provide stable support to adjacent vertebral bodies, and effectively removes the tissue on terminal plate of vertebral body.So this utility model effectively overcomes practical problems more of the prior art thus has very high value and use meaning.
Above-mentioned embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting this utility model.This utility model also has many aspects can improve under the prerequisite of overall thought, all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or change for person skilled in the art scholar.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that this utility model discloses, must be contained by claim of the present utility model.
