Abstract
The utility model relates to the technical field of a medical instrument, in particular to an instrument used for removing a bone in the bone surgery. A slidingly-hammering bone removing knife consists of a long square column shaped knife handle part, a wedge-shaped knife edge part and a knife tail part that is vertical to the knife handle part. The knife handle part is of the long square column shape, the cross section is 1cm*2cm, and the length is more than 12cm; the knife edge part is of the wedge shape, and the direction of the knife edge part is in parallel to the wider surface of the knife handle part; and scales and figures are marked on the knife edge part from a knife edge to a knife handle, and the scales take the centimeter as the unit. The knife tail part is vertical to the knife handle part, and the size of the knife tail part is 1.5cm*2cm*4cm. With the application of the slidingly-hammering bone removing knife, an operator can knock in the bone removing knife in to knock out bone mass conveniently and fast and can accurately control the size of the removed bone block and can avoid the conditions of the accident fracture, the affection to use as the removed bone block is extruded to be deformed and become small and the like as the bone removing knife can swing along multiple directions when being pulled out, thereby saving the surgery duration and relieving the pain of a patient.
Description
Technical field
This utility model relates to technical field of medical instruments, and specifically a kind of bone surgery that is used for is got the apparatus that bone is used.
Background technology
At present in bone surgery, getting the osteotome that bone uses can only be knocked to the blade direction by afterbody along the osteotome long axis direction, when being knocked to enter, osteotome extracts difficulty when sclerotin is pressed tightly than dark or card, often need multi-direction swing to take out, may cause beyond thought fracture during swing, get the bone piece and be extruded the situation such as influence use etc. that diminishes, even need other places to get bone again, caused unnecessary misery to patient.
Summary of the invention
The purpose of this utility model is at above phenomenon, and a kind of osteotome of getting of knocking in, hitting sclerotin that makes things convenient for easily is provided.
The technical solution of the utility model is achieved in that the slip hammering gets osteotome and form by the blade part of the handle of a knife portion of rectangular cylindricality, wedge shape with handle of a knife portion vertical cutter afterbody.Handle of a knife portion is rectangular cylindricality, and the cross section is 1cm * 2cm size, and length is greater than 12cm.Blade part is a wedge shape, the blade part width can be designed to not equidimension such as 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm as required, the blade part direction is parallel with handle of a knife portion broad face, and blade part indicates centimetre being the scale and the expression numeral of unit to the handle of a knife direction from blade.The cutter afterbody is vertical with handle of a knife portion, and cutter afterbody size is 1.5cm * 2cm * 4cm.
Application of the present utility model can make operator, and conveniently will get osteotome easily knocks in, hits sclerotin, can accurately control the size of getting the bone piece, can avoid multi-direction swing causes when extracting osteotome accident fracture, get the bone piece and be extruded the situations such as influencing use that diminishes, save operating time, reduced patient's misery.
