Abstract
The utility model relates to surgical equipment for medical operations of an orthopedics department, particularly provides two technical schemes of a working head of an expansion orthotic device. The first technical scheme is characterized in that a sheet metal cutting knife comprises one strip-shaped sheet metal cutting knife with the top end open, and a cutting knife bulging port is formed on an outer bushing corresponding to the sheet metal cutting knife, and a central baffle plate is fixed on the axial line of the end head of the outer bushing and divides the sheet metal cutting knife and the cutting knife bulging port on the outer bushing on one side of the outer bushing; and the second technical scheme is characterized in that the sheet metal cutting knife comprises two strip-shaped sheet metal cutting knives which correspond to each other, the two top ends of the two strip-shaped sheet metal cutting knives are open, and two cutting knife bulging ports are formed on the outer bushing corresponding to the two strip-shaped sheet metal cutting knives; moreover, a central baffle plate between the two strip-shaped sheet metal cutting knives is fixed on the end head of the outer bushing.
Description
Technical field
The utility model relates to a kind of orthopaedic medical treatment operation operating theater instruments, especially a kind of expansion orthosis working head.
Background technology
At present,, need carry out the operative treatment of vertebroplasty, and in vertebral plasty operation, need to use the balloon dilatation catheter bone cement that after the vertebral body intramedullary expansion forms a cavity, reinjects for alleviating its pain to the patient of compression fracture of vertabral body.But sacculus is long because of there being bony spur that sacculus is punctured in the vertebral body in operation, and sacculus breaks and causes operating time to prolong and the increase surgery cost.For preventing that sacculus from being punctured by bony spur, the general expansion orthosis that adopts is removed Intrapyramidal bony spur in the rotation of vertebral body intramedullary expansion.But have expansion orthosis now in usefulness, because the structure of itself, the bony spur that usually occurs under the cutting in operation is clipped in the sheet metal cutter, make the sheet metal cutter can't return in the trocar sheath, so whole expansion orthosis can't be withdrawed from from the work cover, influenced the carrying out of operation, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of expansion orthosis working head technical scheme, this scheme adopts one or two sheet metal cutteves that the top is open, because the top of sheet metal cutter is open, the bony spur of being clamped by the sheet metal cutter is arranged, when the sheet metal cutter is return, also can be stripped from, so can not influence orthotic the withdrawing from of expansion.
This programme is realized by following two technical measures:
First embodiment: include trocar sheath, cannula cavity has push-pull bar outside, be fixed with the sheet metal cutter on the top of push-pull bar, there is the trocar sheath end socket on telescopic outside top, corresponding sheet metal cutter has the strip cutter to bloat mouth on the telescopic outside sidewall, the characteristics of this programme are that described sheet metal cutter is the bullion sheet cutter that has only a slice top open, have a described cutter to bloat mouth on the trocar sheath corresponding with this sheet metal cutter.The concrete characteristics of this programme also have, and are fixed with a central partition plate on the axis of described trocar sheath end socket, and the cutter on sheet metal cutter and the trocar sheath is bloated mouthful telescopic outside side of separation.
Second embodiment: include trocar sheath, cannula cavity has push-pull bar outside, be fixed with the sheet metal cutter on the top of push-pull bar, there is the trocar sheath end socket on telescopic outside top, corresponding sheet metal cutter has the strip cutter to bloat mouth on the telescopic outside sidewall, the characteristics of this programme are the open bullion sheet cutteves in two tops that described sheet metal cutter has mutual correspondence, have two described cutteves to bloat mouth on the trocar sheath corresponding with this two metal sheets cutter.The concrete characteristics of this programme also have, and also have a central partition plate to be fixed on the trocar sheath end socket between described two sheet metal cutteves.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, adopt one or two sheet metal cutteves that the top is open, because the top of sheet metal cutter is open, and have cutter to bloat mouth on the trocar sheath of corresponding sheet metal cutter, in trocar sheath, also has central partition plate, such structure, even if the bony spur of being clamped by the sheet metal cutter is arranged, when the sheet metal cutter is return, also can be stripped from,, guarantee carrying out smoothly of operation so can not influence orthotic the withdrawing from of expansion from the open top of sheet metal cutter.This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure sketch map of first specific embodiment of this utility model.
Fig. 2 is the part sectional structure sketch map of second specific embodiment of this utility model.
Fig. 3 is the part sectional structure sketch map of Fig. 2 duty.
Among the figure, 1 is the trocar sheath end socket, and 2 is the sheet metal cutter, and 3 for cutter bloats mouth, and 4 is trocar sheath, and 5 is push-pull bar, and 6 is central partition plate.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by two specific embodiment.
First specific embodiment:
By accompanying drawing 1 as can be seen, this programme has trocar sheath 4, at trocar sheath 4 inner chambers push-pull bar 5 is arranged, be fixed with sheet metal cutter 2 on the top of push-pull bar 5, on the top of trocar sheath 4 trocar sheath end socket 1 is arranged, corresponding sheet metal cutter 2 has the strip cutter to bloat mouthfuls 3 on the sidewall of trocar sheath 4, and the described sheet metal cutter 2 of this programme is the bullion sheet cutteves 2 that have only a slice top open, has a described cutter to bloat mouthfuls 3 on the trocar sheath 4 corresponding with this sheet metal cutter 2.On the axis of described trocar sheath end socket 1, be fixed with a central partition plate 6, the cutter on sheet metal cutter 2 and the trocar sheath 4 is bloated mouthful 3 sides of separating at trocar sheath 4.
Second specific embodiment:
By accompanying drawing 2 and 3 as can be seen, this programme has trocar sheath 4, at trocar sheath 4 inner chambers push-pull bar 5 is arranged, be fixed with sheet metal cutter 2 on the top of push-pull bar 5, on the top of trocar sheath 4 trocar sheath end socket 1 is arranged, corresponding sheet metal cutter 2 has the strip cutter to bloat mouthfuls 3 on the sidewall of trocar sheath 4, and the described sheet metal cutter 2 of this programme has the open bullion sheet cutter 2 in two tops of mutual correspondence, has two described cutteves to bloat mouthfuls 3 on the trocar sheath 4 corresponding with this two metal sheets cutter 2.In addition, between described two sheet metal cutteves 2, also have a central partition plate 6 to be fixed on the trocar sheath end socket 1, two metal sheets cutter 2 is separated, help each sheet metal cutter 2 and clamp the separation of bony spur ground.
