Abstract
The utility model provides a technical scheme of a surgical instrument of a novel expansion orthosis. The novel expansion orthosis comprises a work head and an operation device, wherein the work head is provided with an outer sleeve pipe; a push-pull rod coaxial with the outer sleeve pipe is arranged in the inner cavity of the outer sleeve pipe; a strip-shaped elastic cutter is fixed at the top end of the push-pull rod; an outer sleeve pipe end socket is arranged at the top end of the outer sleeve pipe; a strip-shaped cutter protruding port corresponding to the elastic cutter is arranged on the outer sleeve pipe side wall at the end of the outer sleeve pipe end socket; and a central baffle which is coaxial with the outer sleeve pipe and is connected with the outer sleeve pipe end socket is arranged in the outer sleeve pipe. According to the technical scheme, a fixing handle provided with a fixing sleeve is arranged on the operation device, the fixing sleeve is fixedly connected with the outer sleeve pipe, the push-pull rod penetrates through the fixing handle and is fixedly connected with a push-pull handle, and a positioning bolt for determining the position of the push-pull rod is further arranged on the fixing sleeve.
Description
Technical field
The utility model relates to a kind of operating theater instruments of orthopaedic medical treatment operation usefulness, especially a kind of novel expanded orthosis.
Background technology
At present, to the patient of compression fracture of vertabral body, need carry out the operative treatment of vertebroplasty for alleviating its pain, 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.But often because there being bony spur that sacculus is punctured in the vertebral body, sacculus breaks and causes operating time to prolong and the increase surgery cost sacculus in operation.Be 201120086384.5 patents that prevent that sacculus from being punctured event the applicant application and being authorized by Patent Office of State Intellectual Property Office by bony spur; this patent protection a kind of technical scheme of expanding the orthosis head; but; the expansion orthosis includes working head and operating means; have only working head in the prior art and do not have complete expansion orthosis, this is the existing in prior technology weak point.
Summary of the invention
Technical problem to be solved in the utility model is exactly at the existing in prior technology deficiency, and a kind of novel expanded orthotic technical scheme is provided, and this scheme is to have adopted known working head, and adopts the operating means of push-pull configuration.
This programme is realized by following technical measures: a kind of novel expanded orthosis, include working head and operating means, described working head has trocar sheath, cannula cavity has the push-pull bar coaxial with trocar sheath outside, the elasticity cutter that bar shaped is fixedly arranged on the top of described push-pull bar, on the top of trocar sheath the trocar sheath end socket is arranged, corresponding elasticity cutter has the cutter of strip to protrude mouth on the trocar sheath sidewall of trocar sheath seal head end, coaxial and be connected with central partition plate with the trocar sheath end socket with trocar sheath in trocar sheath, the characteristics of this programme are the fixed handles that described operating means has a band fixed cover, this fixed cover is fixedlyed connected with described trocar sheath, described push-pull bar passes described fixed handle fixedlys connected with a push and pull bar, also has the bolt of a definite push-pull bar position at described fixed cover.The concrete characteristics of this programme also have, and the elasticity cutter of described bar shaped is to adopt elastic sheet metal to make.The elasticity cutter of described bar shaped has only one, on described trocar sheath sidewall the cutter that should the elasticity cutter have only a strip is protruded mouthful, in the inboard of the elasticity cutter of bar shaped central partition plate is arranged.The elasticity cutter of described bar shaped has two, to having the cutter of two strips to protrude mouth by the elasticity cutter, between the elasticity cutter of two bar shapeds central partition plate is arranged on described trocar sheath sidewall.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because the fixed handle of a band fixed cover is arranged in operating means, this fixed cover is fixedlyed connected with trocar sheath, push-pull bar passes described fixed handle fixedlys connected with a push and pull bar, also has the bolt of a definite push-pull bar position at described fixed cover.This structure, push-pull bar is taken in the elasticity cutter in the trocar sheath when push and pull bar is pulled out, and push-pull bar will make the elasticity cutter protrude when push and pull bar pushes, and this moment, rotational fixation handle and push and pull bar just can be implemented operation.This shows that the technical solution of the utility model compared with prior art all has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the part sectional structure sketch map of this utility model specific embodiment.
Among the figure, 1 is the trocar sheath end socket, and 2 is the elasticity cutter, dividing plate centered by 3, and 4 is that cutter protrudes mouthful, and 5 is trocar sheath, and 6 is push-pull bar, and 18 is fixed cover, and 19 is bolt, and 20 is fixed handle, and 21 is push and pull bar.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing as can be seen, the novel expanded orthosis of this programme has working head and operating means, described working head has trocar sheath 5, at trocar sheath 5 inner chambers the push-pull bar 6 coaxial with trocar sheath 5 arranged, the elasticity cutter 2 that bar shaped is fixedly arranged on the top of described push-pull bar 6, on the top of trocar sheath 5 trocar sheath end socket 1 is arranged, corresponding elasticity cutter 2 has the cutter of strip to protrude mouthfuls 4 on trocar sheath 5 sidewalls of trocar sheath end socket 1 end, and is coaxial and be connected with central partition plate 3 with trocar sheath end socket 1 with trocar sheath 5 in trocar sheath 5.The elasticity cutter 2 of the described bar shaped of this specific embodiment is to adopt elastic sheet metal to make.The elasticity cutter 2 of described bar shaped has two, to having the cutter of two strips to protrude mouth 4 by elasticity cutter 2, between the elasticity cutter 2 of two bar shapeds central partition plate 3 is arranged on described trocar sheath 5 sidewalls.The described operating means of this programme has the fixed handle 20 of a band fixed cover 18, this fixed cover 18 is fixedlyed connected with described trocar sheath 5, described push-pull bar 6 passes described fixed handle 20 fixedlys connected with a push and pull bar 21, also has the bolt 19 of definite push-pull bar 6 positions at described fixed cover 18.
