Abstract
The utility model relates to orthopaedic medical treatment operation operating theater instruments, especially a kind of technical scheme of expansion orthotic device cutting head is provided, this programme includes trocar sheath, cannula cavity has push-pull bar outside, two sheet metal cutteves are fixed with on the top of push-pull bar, trocar sheath end socket is had on the top of trocar sheath, on the sidewall of trocar sheath, corresponding two sheet metal cutteves have two strip cutteves to bloat mouth, mouth can be bloated at corresponding two cutteves with this two metal sheets cutter to bloat, between described two sheet metal cutteves, also have a central partition plate to be fixed on trocar sheath end socket, the feature of this programme is that the distance that two described cutteves bloat between the top of mouth and trocar sheath end socket exists deviation.The concrete feature of this programme also has, and it is within 2-20 millimeter that two described cutteves bloat the deviation that the distance between the top of mouth and trocar sheath end socket exists.
Description
Technical field
The utility model relates to a kind of orthopaedic medical treatment operation operating theater instruments, especially a kind of expansion orthotic device cutting head.
background technology:
At present, to the patient of compression fracture of vertabral body, needing to carry out the operative treatment of vertebroplasty for alleviating its pain, and in pyramid plastic operation, needing application balloon dilatation catheter to reinject after vertebral body intramedullary expansion forms a cavity bone cement.But sacculus is long because there being bony spur to be punctured by sacculus in vertebral body in operation, sacculus breaks and causes operating time to extend and increase surgery cost.For preventing sacculus from being punctured by bony spur, the general expansion orthotic device that adopts rotates the Intrapyramidal bony spur of removal at vertebral body intramedullary expansion.To be applied for by the applicant and the application number of being authorized by State Intellectual Property Office is 201120086384.5, title: a kind of utility model patent of working head of expansion orthotic device is exactly the technical scheme addressed this problem, but the cutter of the program two cutteves drum outlet tip is identical apart from the distance of trocar sheath end socket, so the space can cut in the axial direction is identical, inapplicable larger axis is to the cutting in space, and this is the weak point existing for prior art.
summary of the invention:
The purpose of this utility model, be exactly for the deficiency existing for prior art, and a kind of expansion orthotic device cutting head technical scheme is provided, the program adopts two cutter distances bloated between the top of mouth and trocar sheath end socket to there is certain deviation, and cutter can be made to strengthen in the cutting space of axis.
This programme is achieved by the following technical measures: expansion orthotic device cutting head, include trocar sheath, cannula cavity has push-pull bar outside, two sheet metal cutteves are fixed with on the top of push-pull bar, trocar sheath end socket is had on the top of trocar sheath, on the sidewall of trocar sheath, corresponding two sheet metal cutteves have two strip cutteves to bloat mouth, mouth can be bloated at corresponding two cutteves with this two metal sheets cutter to bloat, between described two sheet metal cutteves, also have a central partition plate to be fixed on trocar sheath end socket, the feature of this programme is that the distance that two described cutteves bloat between the top of mouth and trocar sheath end socket exists deviation.The concrete feature of this programme also has, and it is within 2-20 millimeter that two described cutteves bloat the deviation that the distance between the top of mouth and trocar sheath end socket exists.
The beneficial effect of this programme can be learnt according to describing of such scheme, and due in this scenario, the distance adopting two cutteves to bloat between the top of mouth and trocar sheath end socket exists deviation.This structure, can make two cutteves bloat maximum radius that when mouth bloats, two cutteves bloat not at grade at cutter, therefore increase the cutting space in axis.As can be seen here, this utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
accompanying drawing illustrates:
Fig. 1 is the partial cross structural representation of this utility model detailed description of the invention.
Fig. 2 is the partial cross structural representation of Fig. 1 duty.
In figure, 1 is trocar sheath end socket, and 2 is sheet metal cutter, and 3 bloat mouth for cutter, and 4 is trocar sheath, and 5 is push-pull bar, dividing plate centered by 6.
detailed description of the invention:
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, this programme has trocar sheath 4, push-pull bar 5 is had at trocar sheath 4 inner chamber, two corresponding sheet metal cutteves 2 are fixed with on the top of push-pull bar 5, trocar sheath end socket 1 is had on the top of trocar sheath 4, on the sidewall of trocar sheath 4, corresponding two sheet metal cutteves 2 have strip cutter to bloat mouth 3, mouth 3 can be bloated at corresponding two cutteves with this two metal sheets cutter 2 to bloat, between described two sheet metal cutteves 2, also have a central partition plate 6 to be fixed on trocar sheath end socket 1, there is deviation in the distance that two cutteves described in this programme bloat between the top of mouth 3 and trocar sheath end socket 1, this deviation is within 2-20 millimeter, the deviation that this detailed description of the invention adopts is 10 millimeters.
Claims (2)
1. an expansion orthotic device cutting head, include trocar sheath, cannula cavity has push-pull bar outside, two sheet metal cutteves are fixed with on the top of push-pull bar, trocar sheath end socket is had on the top of trocar sheath, on the sidewall of trocar sheath, corresponding two sheet metal cutteves have two strip cutteves to bloat mouth, mouth can be bloated at corresponding two cutteves with this two metal sheets cutter to bloat, between described two sheet metal cutteves, also have a central partition plate to be fixed on trocar sheath end socket, it is characterized in that: the distance that two described cutteves bloat between the top of mouth and trocar sheath end socket exists deviation.
2. expansion orthotic device cutting head according to claim 1, is characterized in that: it is within 2-20 millimeter that two described cutteves bloat the deviation that the distance between the top of mouth and trocar sheath end socket exists.
