Abstract
The utility model relates to an operating device for the hand surgery department, and in particular relates to a bone fetcher for hand surgery. The bone fetcher comprises a protective sleeve, a bone fetch cylinder and an ejector rod, wherein the bone fetch cylinder is sleeved in the protective sleeve; and the ejector rod is sleeved in the bone fetch cylinder. Compared with the prior art, the bone is fetched by utilizing the bone fetch cylinder, the bone lock bolt can be taken out from the bone cylinder through the ejector rod, the surgical cut is small, and the periosteum does not need to be peeled off widely.
Description
Technical field
This utility model relates to a kind of hands surgical operating apparatus, and particularly a kind of hands surgery is got bone object.
Background technology
The hands surgical operation relates to the surgical procedures technology of hands and wrist scope.Because hand refers to, metacarpal bone and carpal bone sclerotin are tiny, fracture or bone tumor need a small amount of bone grafting after striking off swollen thing, use conventional bone surgery set and get bone and need to cut for the bone zone, use osteotome and dig out the bulk sclerotin, get usually unnecessary demand bone amount of bone amount.
Summary of the invention
Goal of the invention of the present utility model is to overcome the prior art deficiency, and a kind of bone of getting on a small quantity is provided, and can what select to get bone object diameter and chiseling depth according to need bone amount, and operative incision is little, and the hands surgery that does not need extensively to peel off periosteum is got bone object.
This utility model adopts following technical scheme:
A kind of hands surgery is got bone object, comprises protection sleeve, gets the bone cylinder, and push rod is characterized in that: be set with in the described protection sleeve and get the bone cylinder, get in the bone cylinder and be set with push rod.
This utility model compared with prior art utilizes and to get the bone cylinder and get bone, will get by push rod that institute's bone bolt of getting takes out in the bone cylinder again, and operative incision is little, need not extensively to peel off periosteum.
Preferred version of the present utility model is:
Get bone cylinder lower end and be made as and get the bone sword, get bone cylinder upper end and be provided with shoulder; The diameter of shoulder is greater than the interior diameter of protection sleeve; Get the bone drum outer wall and be provided with scale.
One end of push rod is provided with boss, and the diameter of boss is greater than the interior diameter of getting the bone cylinder.
Described push rod length is equal to or greater than gets bone tube length degree.
Get connecting handle on the shoulder of bone cylinder.
Described push rod is cylindrical structural.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that this utility model is got the bone working state figure.
Fig. 3 gets bone done state figure.
The specific embodiment
Below in conjunction with drawings and Examples in detail this utility model is described in detail:
A kind of hands surgery is got bone object, referring to accompanying drawing 1 to accompanying drawing 3, among the figure: protection sleeve 1, get bone cylinder 2, get bone sword 3, push rod 4, handle 5, shoulder 6, boss 7, scale 8.Muscle 9; Bone 10; Bone bolt 11.
In the present embodiment, be set with in the protection sleeve 1 and get bone cylinder 2, get and be set with push rod 4 in the bone cylinder 2; Getting bone object 2 can be in protection sleeve 1 interior slip, and push rod 4 can got bone object 2 interior slips.
The lower end of getting bone cylinder 2 is to get bone sword 3, gets bone cylinder 2 upper ends and is provided with shoulder 6; The diameter of shoulder 6 is greater than the interior diameter of protection sleeve 1; Get bone cylinder 2 outer walls and be provided with scale 8.
The upper end of push rod 4 is provided with boss 7, and the diameter of boss 7 is greater than the interior diameter of getting bone cylinder 2.Push rod 4 length are equal to or greater than gets bone cylinder 2 length; The length of push rod 4 is greater than the length of getting bone cylinder 2 in this enforcement, is beneficial to smoothly getting sclerotin is ejected.Get connecting handle 5 on the shoulder of bone cylinder 2.Push rod 4 adopts cylindrical structural; Also can adopt the cylindrical tube structure of hollow.
In the use procedure, first push rod 4 treating the preponderant disease instead of the secondary disease bone cylinders 2 are taken out for subsequent usely, get bone cylinder 2 and be inserted in the protection sleeve 1 and rely on free gravity to glide, get shoulder 6 above the bone cylinder 2 by hammering, get bone sword 3 under the effect of external force, getting bone is cut off, turning handle 5 screws out bone bolt 11, gets bone and finishes; By after getting bone object 2 bone bolt 11 being taken out, push rod 4 is placed get in the bone object 2 again, bone bolt 11 is ejected.
Get bone object 2 according to what hands stated that actual needs selects suitable diameter, to reach the requirement of micro-wound bone taking.
