Abstract
The utility model provides a technical scheme of a surgical instrument, and particularly discloses a dilation orthosis. The scheme includes that the dilation orthosis comprises a working head and an operating device, the working head is provided with an outer cannula, an inner cavity of the outer cannula is provided with a push-pull rod which is coaxial with the outer cannula, a strip-shaped elastic cutter is fixed to the top of the push-pull rod, an outer cannula seal head is arranged on the top of the outer cannula, an elongated cutter protruded opening corresponding to the elastic cutter is arranged on the side wall of the outer cannula and is positioned at an end of the outer cannula seal head, and a center partition plate which is coaxial with the outer cannula and is connected with the outer cannula seal head is arranged in the outer cannula. The operating device is provided with a first handle and a second handle which are hinged with each other in a crossed manner, the outer cannula is fixedly connected to the top of the second handle, the push-pull rod is hinged on one side of the first handle, and a locking mechanism is further arranged between the first handle and the second handle.
Description
Technical field
The utility model relates to a kind of operating theater instruments of orthopaedic medical treatment operation usefulness, especially a kind of expansion 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 provides a kind of expansion orthotic technical scheme, and this scheme is to have adopted known working head, and adopts the operating means of scissors structure.
This programme is realized by following technical measures: the expansion 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 handle one and the handles two that described operating means has two cross-articulation, the fixedly connected described trocar sheath in the top of described handle two, described handle is hinged described push-pull bar first, also has retaining mechanism between described handle one and handle two.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 operating means has handle one and the handle two of two cross-articulation, the fixedly connected trocar sheath in the top of described handle two, described handle is hinged push-pull bar first, also has retaining mechanism between described handle one and handle two.This structure, when handle one and handle two opened, push-pull bar was taken in the elasticity cutter in the trocar sheath, when compression handle one and handle two, push-pull bar will make the elasticity cutter protrude, this moment swing handle once and handle two can implement to perform the operation.This shows that four kinds of technical schemes of the present utility model compared with prior art all have 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 12 is that handle one, 13 is retaining mechanism, 14 is handle two.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by four specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing as can be seen, the expansion 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 only one, on described trocar sheath 5 sidewalls the cutter that should elasticity cutter 2 have only a strip is protruded mouthfuls 4, in the inboard of the elasticity cutter 2 of bar shaped central partition plate 3 is arranged.The described operating means of this programme has handle 1 and the handle 2 14 of two cross-articulation, the fixedly connected described trocar sheath 5 in the top of described handle 2 14, one 12 hinged described push-pull bars 6 of described handle, between described handle 1 and handle 2 14, also has retaining mechanism 13, this retaining mechanism 13 can adopt any known retaining mechanism, and what this specific embodiment adopted is the retaining mechanism of groove and projection.
