Description
Technical field
The present invention relates to a kind of operating theater instruments, be specifically related to a kind of bone object of getting.
Background technology
In operation process; Sometimes need on patient's ilium, get spongy bone, be used for the transplanting of bone, the existing bone object of getting generally comprises and gets the bone urceolus; Front end end getting the bone urceolus is provided with cutting; When the bone urceolus was got in rotation, the cutting of its front end was cut bone and is made it be cylinder, and the spongy bone after the incision is contained in the appearance bone cavity of getting the bone urceolus.
The existing practice is; Directly will get bone object takes out from ilium; Under normal conditions, the cylindrical spongy bone of getting in the bone urceolus can break off with the ilium main part, after getting the taking-up of bone urceolus; The cylindrical spongy bone that is taken out can be kept to be got in the bone urceolus, in the treating the preponderant disease instead of the secondary disease bone urceolus spongy bone taking-up is used for transplanting again.
The spongy bone of getting in the bone urceolus does not break off with the ilium main part, when the bone urceolus is got in taking-up but in some cases; Get in the spongy bone treating the preponderant disease instead of the secondary disease bone urceolus in the bone urceolus, and stay the ilium main part, the effect that bone is got in influence; Even get bone once more, and not only prolong the injured time, also increase wound to the patient; If it is unsuccessful repeatedly to get bone, can cause adverse effect to the patient.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of bone object of getting is provided, the present invention can be better takes out spongy bone, and it is higher to get bone efficient, and reduces the wound to the patient.
Its technical scheme is following.
A kind of bone object of getting comprises and gets bone urceolus and shearing device that the front end end of getting the bone urceolus is provided with cutting, and the rear end is provided with first handle; Getting bone outer cylinder front end end leans on the inwall of position, back to be provided with the arc negative camber; This arc negative camber its internal diameter backward increases gradually; Shearing device comprises section, connecting portion and second handle, and section is connected with second handle through connecting portion, and first handle and second handle expose; The inboard of arc negative camber is pressed close in section, at the columniform appearance bone cavity of the inner formation of connecting portion.
Describe in the face of the further technical scheme of the present invention down.
The internal diameter of said section is greater than the said internal diameter of getting bone outer cylinder front end end.
Said section is at least two, circumferentially is uniformly distributed with along the said bone urceolus of getting.
Said second handle is positioned at the rear end of said first handle, and exposes with respect to said first handle.
Said connecting portion is an inner barrel, and this inner barrel is sheathed on said getting in the bone urceolus.
Perhaps, said connecting portion comprises that connecting ring reaches at least two and connects spoke longitudinally, and each connects spoke and evenly is provided with along the said bone outer tube inner wall of getting; The front end of connecting ring is connected with each said section, and the rear end is connected spoke and connects with each.
Said first handle and second handle are the semicircle sphere, and the plane of first handle and second handle is relative.
Facing advantage of the present invention or principle down describes:
1, in use, get the bone urceolus, get the cutting of bone outer cylinder front end spongy bone is cut through the first handle rotation; Spongy bone after the incision is contained in the bone cavity, when the amount of the spongy bone in holding bone cavity meets the requirements, presses section through second handle again; Spongy bone and ilium main part through section will be held in the bone cavity are broken off; More thorough when getting bone like this, efficient is higher, also reduces the wound to the patient;
2, the internal diameter of said section, contracts after the section when the bone urceolus is got in rotation greater than the said internal diameter of getting bone outer cylinder front end end, can not interfere with each other with the spongy bone that holds in the bone cavity;
3, the connecting portion of shearing device is used for the extremely section of transmission of power with second handle, can be inner barrel, also can and connect spoke by connecting ring and constitute, but the inside of connecting portion need have columniform inner chamber, holds bone cavity so that form.
Description of drawings
Fig. 1 is the said structure chart of getting bone object of the embodiment of the invention;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Description of reference numerals:
1, gets the bone urceolus, 2, cutting, 3, first handle, 4, the arc negative camber, 5, section, 6, connecting ring, 7, second handle, 8, hold bone cavity, 9, connect spoke.
The specific embodiment
Be elaborated in the face of embodiments of the invention down.
Like Fig. 1, shown in Figure 2, a kind of bone object of getting comprises and gets bone urceolus 1 and shearing device that the front end end of getting bone urceolus 1 is provided with cutting 2, and the rear end is provided with first handle 3; Getting bone urceolus 1 front end end leans on the inwall of position, back to be provided with arc negative camber 4; This arc negative camber 4 its internal diameter backward increases gradually; Shearing device comprises section 5, connecting portion and second handle 7, and section 5 is connected with second handle 7 through connecting portion, and first handle 3 and second handle 7 expose; The inboard of arc negative camber 4 is pressed close in section 5, at the columniform appearance bone cavity 8 of the inner formation of connecting portion.
Wherein, the internal diameter of section 5 is greater than the internal diameter of getting bone urceolus 1 front end end.Said section 5 is a plurality of, circumferentially is uniformly distributed with along getting bone urceolus 1.Said connecting portion comprises that connecting ring 6 reaches at least two and connects spoke 9 longitudinally, and each connects spoke 9 and evenly is provided with along getting bone urceolus 1 inwall; The front end of connecting ring 6 is connected with each section 5, and the rear end is connected spoke 9 and connects with each.
Second handle 7 is positioned at the rear end of first handle 3, and exposes with respect to first handle 3.First handle 3 and second handle 7 are the semicircle sphere, and first handle 3 is relative with the plane of second handle 7.
Present embodiment has following advantage:
1, in use, get bone urceolus 1, get the cutting 2 of bone urceolus 1 front end spongy bone is cut through first handle 3 rotations; Spongy bone after the incision is contained in the bone cavity 8, when the amount of the spongy bone in holding bone cavity 8 meets the requirements, presses section 5 through second handle 7 again; Through 5 spongy bone and the disconnection of ilium main parts that will hold in the bone cavity 8 of cutting into slices; More thorough when getting bone like this, efficient is higher, also reduces the wound to the patient;
2, the internal diameter of section 5, contracts after the section 5 when bone urceolus 1 is got in rotation greater than the internal diameter of getting bone urceolus 1 front end end, can not interfere with each other with the spongy bone that holds in the bone cavity 8;
3, the connecting portion of shearing device is used for transmission of power with second handle 7 to cutting into slices 5, can be inner barrel, also can and connect spoke 9 by connecting ring 6 and constitute, but the inside of connecting portion need have columniform inner chamber, holds bone cavity 8 so that form.
More than be merely specific embodiment of the present invention, do not limit protection scope of the present invention with this; Any replacement and the improvement on the basis of not violating the present invention's design, done all belong to protection scope of the present invention.
