Abstract
The utility model discloses a bone fetcher, which comprises a bone fetching sleeve, a T-shaped handle and a crossbar, wherein a blade is arranged at the tail end of the T-shaped handle, and one end of the bone fetching sleeve is in a jagged shape; one end of the bone fetching sleeve is provided with an opening. A crossbar channel is arranged at one end, provided with the opening, of the bone fetching sleeve in the direction perpendicular to the axis of the sleeve, and the crossbar is inserted into the crossbar channel before the bone fetching sleeve is inserted into a human body; after the bone fetching sleeve enters the sclerotin by rotating the crossbar, the crossbar is drawn out, the T-shaped handle with the blade extends into the bone fetching sleeve through the opening of the bone fetching sleeve, and the blade is rotated to cut off the connection between the sclerotins fetched from the bone fetching sleeve. The bottom end and the two sides of the blade are edges. The bone can be fetched once by a trephine, so that the trauma to patients is reduced, the surgery purpose can be achieved, the suffering of patients can be reduced, and thus the practicality is strong.
Description
Technical field
This utility model relates to operating theater instruments research field, particularly a kind of bone object of getting.
Background technology
In bone surgery process, sometimes need to take from body bone at patient's ilium and transplant for bone.Mainly contain at present two kinds and get bone method, a kind of is directly to get ilium with osteotome, osteotome, and the easy injured blood vessel of this method is neural, and wound is very large, to patient, causes very large misery.Another is to adopt trepan to get bone, and the bone of taking-up is retained in to be got in bone object, then takes out sclerotin.But what get bone cutting due to trepan is sclerotin contact with ilium, and its lower end is separation, is difficult for disposable taking-up, thereby has affected the effect of getting bone, even sometimes needs again to operate and gets bone, has increased the wound to patient.
Utility model content
Main purpose of the present utility model is that the shortcoming that overcomes prior art is with not enough, a kind of bone object of getting is provided, and this is got bone object and can disposablely take out when adopting trepan to get bone, thereby reduces the wound to patient, when reaching operation object, can reduce patient's misery, practical.
The purpose of this utility model realizes by following technical scheme: a kind of bone object of getting, and comprise and get bone sleeve, a T-handle and cross bar, this T-handle end is provided with blade; Getting bone sleeve one end is zigzag, and one end is provided with opening; In the one end of getting bone sleeve and be provided with opening, perpendicular to the direction of sleeve axis, be provided with a cross bar passage, in getting bone sleeve insertosome before, cross bar is inserted in this cross bar passage; After rotating this cross bar and making to get bone sleeve and enter in sclerotin, extract cross bar out, the T-handle treating the preponderant disease instead of the secondary disease bone sleeve openings with blade is reached to the inside of getting bone sleeve, rotating blade is got the connection between the sclerotin taking out in bone sleeve for cutting off.By this being set with the T-handle of blade, can reach the object of disposable taking-up sclerotin.Meanwhile, by a cross bar is set, can handled easily person control and get bone sleeve, and in insertosome time rotation to get bone sleeve more laborsaving.
Concrete, described T-handle comprises mobile jib and T shape handle, and mobile jib end is connected with blade by a transition connecting rod, and the diameter of transition connecting rod is less than mobile jib.Transition connecting rod diameter is less, needs to insert to get in bone cavity in getting the process of bone, can under the mechanical strength that guarantees apparatus, reduce getting the occupy-place volume of bone passage.
Further, described blade is blade in its bottom and both sides.
Concrete, described in get bone sleeve outer surface and be marked with the scale that enters the degree of depth in bone for estimating blade.Thereby can real-time estimation to the position of blade.
Preferably, under described T-handle, certain position place is provided with stopping means.By arranging that this stopping means can be avoided because maloperation to cause blade to enter sclerotin inside too dark, increase unnecessary wound, improve the safety when getting bone object and using.
Preferably, described in get bone sleeve inner and be divided into two sections, wherein one section is the bone cavity of getting of a circle, be arranged near zigzag one end, for taking sclerotin, the service aisle that another section is T-handle.
Work process of the present utility model: during use, cross bar is through cross bar passage, by cross bar, rotate and get bone sleeve, the cortical bone of the saw cut ilium on zigzag one end, getting bone sleeve enters in body, cut sclerotin bag is contained in to be got in bone cavity, when reaching the amount of patient's requirement, take out cross bar, insertion is with the T-handle of blade, blade is by the sclerotin cutting of getting in bone sleeve, make its interior section separated, reduce the resistance of inner stress and taking-up sclerotin, rotating blade firmly, the sclerotin bottom that makes to get in bone sleeve is separated, thereby can effectively take out sclerotin, the wound of minimizing to patient.
Compared with prior art, tool has the following advantages and beneficial effect this utility model:
1, this utility model proposes to increase a T-handle with blade on original basis of getting bone object, thereby can make the disposable taking-up of sclerotin, reduces patient's misery, practical.
2, the utility model proposes at the existing near-end of getting bone sleeve one cross bar is set, thereby can be more convenient, laborsaving in the time getting bone sleeve and insert in human body,
3, this utility model is provided with stopping means on T-handle, thereby can avoid maloperation and cause patient's bed above, has increased the safety of getting bone object.
