Abstract
Disclosed is a disposable bone taking and grafting device, which is composed of a sleeve with a handle, an injection syringe type marrow absorbing and storage tube, a piston bone harvesting dual-purpose handle, a rubber seal ring and a metal drill. The utility model is characterized in that it belongs to the disposable article, which is easy to carry and operate with low cost. The utility model is a promising medical update product, and is also the ideal product for enterprises that produce disposable aseptic medical instrument.
Description
This utility model relates to technical field of medical instruments.
It is one of present clinical difficult disease that delayed union of fracture and bone does not connect connect, and adopting the treatment of operation bone grafting is the method comparatively reliably of generally acknowledging at present, has many patients to need repeatedly bone grafting just can make fracture healing.Present operation method is to get the long otch of bone and bone graft area work from body, carrying out periosteum stripping then and get bone with osteotome, cutting bone grafting to the bone grafting face again.This surgical injury is big, and amount of bleeding is many, misery is big, periosteum stripping and destroy local blood fortune and influence union of fracture, damage and repeatedly operation back anatomical tissue structure disorder and operation bone grafting have the possibility that causes neural blood vessel to damage.
It is few that the purpose of this utility model is to design a kind of damage, painful little, uses easy to carry getting---bone grafting device.
This utility model is to be made of accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5.Accompanying drawing 1 is the overall structure sketch map of this utility model, and accompanying drawing 2 is inhaled storage spinal canal 2 for syringe-type, by the structure of pipe shaft dummy pipe 7, steam vent 6; Accompanying drawing 3 is the structure of band sleeve pipe 1; The structure that accompanying drawing 4 is got the dual-purpose handle 3 of bone for piston is made up of handle bar, hollow marrow 8, gim peg 9, rubber seal 4, groove; Accompanying drawing 5 is the structure of metal bit 5.
Disposable getting---bone grafting device is inhaled storage spinal canal 2, piston by band sleeve pipe 1, syringe-type and is got the dual-purpose handle 3 of bone, rubber seal 4, metal bit 5 and form jointly.Band sleeve pipe 1 is for penetrating the hollow metal member, and the best is made for rustless steel.Front end has the external thread wire structure to be convenient to be fixed on the sclerotin; It is disposable injection moulding member that syringe-type is inhaled storage spinal canal 2, and there is a steam vent 6 the front end side, and the length of dummy pipe 7, size and band sleeve pipe 1 coincide; Piston is got the dual-purpose handle of bone 3 and is disposable injection moulding member, and the handle bar has the hollow pipeline 8 of a front opening, and there is a drill bit gim peg 9 at handle bar front end 1/4 place, and handle bar front end has the fixing groove of rubber seal.The length of metal bit 5 is no more than the length that piston is got the hollow pipeline 8 of the dual-purpose handle 3 of bone.This utility model is finished like this with above-mentioned structure member: at first select the ideal sterile-processed back of bone bone water position ilium of getting of human body to cut skin exposure surface of bone, will be with 1 rotation of sleeve pipe to be fixed on the sclerotin; Metal bit 5 is inserted in piston to be got and leaves 1/3 metal bit 5 in the hollow pipeline 8 of the dual-purpose handle 3 of bone outside hollow pipeline 8 and fixing with drill bit gim peg 9, dress rubber seal 4 is got dual-purpose handle 3 front ends of bone in piston, is inserted in the syringe-type suction storage spinal canal 2 with being about to its integral body; By the band sleeve pipe 1 that is fixed on the ilium piston is got the spiral forward propelling of bone two handles 3 then, local sclerotin is smashed to pieces, piston being got dual-purpose handle 3 pumpbacks of bone sucks in the syringe-type suction storage spinal canal 2 broken bone (bone mud) again, again metal bit 5 is retracted into hollow pipeline 8 internal fixation, at this moment the piston piston function of having got 3 one-tenth of the dual-purpose handles of bone, getting bone marrow by the sclerotin position that infirmary need implant other fracture back disunion of consubstantiality, is finished and is got---the work of bone grafting marrow.
This utility model advantage is that product is disposable products, and use, easy to carry, simple to operate can be made into three specification products large, medium and small number.
The optimum implementation of this utility model is: the band sleeve pipe made from rustless steel 1 is inserted in the dummy pipe 7 of inhaling storage spinal canal 2 with the syringe-type of medical plastic injection mo(u)lding; Metal bit 5 is filled in the piston of injection mo(u)lding and got in the hollow pipeline 8 of the dual-purpose handle 3 of bone, and, then piston is got dual-purpose handle 3 integral body of bone and filled in the assembly unit of finishing whole utility model in the syringe-type suction storage spinal canal 2 with stainless gim peg 9 fixing metal drill bits 5.
