The specific embodiment
The guider of the solid pedicle nail of breast lumbar vertebra as shown in Figure 1 and 2, comprise the conical pipe 1, cylindrical channel pipe 2 and the fixed handle 3 that connect successively from front to back, on fixed handle 3, have the through hole 31 that the rear end mouth of pipe with cylindrical channel pipe 2 connects, the internal diameter of this through hole 31 equates with the internal diameter of the cylindrical channel pipe 2 rear end mouths of pipe; The cross section of conical pipe 1 increases from front to back gradually; The mouth of pipe of conical pipe 1 rear end docks with the mouth of pipe of cylindrical channel pipe 2 front ends, and forms annular connecting line 4, along this annular connecting line 4, offers many arcuate grooves 5 of mutually separating; On along the middle part of a part of arcuate groove 5 wherein to conical pipe 1 tube wall of conical pipe 1 front end mouth of pipe direction, connect and offer long straight trough 6, the middle part of remaining arcuate groove 5 is to connecting and offer short straight trough 7 on conical pipe 1 tube wall of conical pipe 1 front end mouth of pipe direction, on conical pipe 1 tube wall along from the conical pipe 1 front end mouth of pipe to the direction of short straight trough 7 front ends, offer first rear end of straight trough 8, the first straight troughs 8 and the front end of short straight trough 7 separately and form the first connecting portion 9; Long straight trough 6, short straight trough 7 and the first straight trough 8 are all symmetrical arranged with the centerline axis of conical pipe 1.
The nail of putting that this guider is specially adapted to the solid pedicle nail 10 of breast lumbar vertebra operates, and wherein, conical pipe 1, cylindrical channel pipe 2 and fixed handle 3 can adopt the medical stainless steel that medical alloy or model are 317-L to make.Especially, arcuate groove 5 and long straight trough 6 form and are "T"-shaped cell body, and the diameter of through hole 31 is 2mm, also can in the scope of 1mm ~ 3mm, select, and is beneficial to the elementary guide effect that solid pedicle nail 10 enters through hole 31, cylindrical channel pipe 2.The tapering of excellent conical pipe 1 is 8 °, also can within the scope of 5 ° ~ 10 °, select, and is beneficial to keep the clamping force of conical pipe 1, can obtain again good in guide effect simultaneously.
General is that conical pipe 1 is formed to elastic clamping force, that a plurality of straight troughs that run through the conical pipe 1 front end mouth of pipe and the rear end mouth of pipe are directly set, this mode struts after conical pipe 1 at solid pedicle nail 10, conical pipe 1 undercapacity, be difficult to form the accurate centering guiding that enough clamping forces keep solid pedicle nail 10, and repeatedly strut the also fragile conical pipe being ruptured 1 tube wall, and the conical pipe 1 of this guider is different from existing this structure.As shown in Figure 2, when solid pedicle nail 10, using this guider and put when operation nail as guiding, hand-held or exterior mechanical hands clamps fixed handle 3, the ailhead of solid pedicle nail 10 enters conical pipe 1 by through hole 31 and cylindrical channel pipe 2 successively, under the effect of long straight trough 6, solid pedicle nail 10 cracks the tube wall of whole conical pipe 1 along long straight trough 6, simultaneously, under the effect of arcuate groove 5, can prevent that conical pipe 1 tube wall from tearing along annular connecting line 4, keep the elasticity of conical pipe 1 tube wall simultaneously; Short straight trough 7 and the first straight trough 8 are now by the internal division effect plaing conical pipe 1 tube wall, make conical pipe 1 tube wall more full of elasticity, to clamp solid pedicle nail 10, the first connecting portion 9 plays the interconnect function to conical pipe 1 tube wall simultaneously, can keep structural strength, guarantee that solid pedicle nail 10 obtains enough clamping forces.
On along annular connecting line 4 to conical pipe 1 tube wall of conical pipe 1 front end mouth of pipe direction, also have a plurality of the second straight troughs 11, the front end mouth of pipe of each second straight trough 11 and conical pipe 1 is to interval and form the second connecting portion 12.The second straight trough 11 struts effect and offers the elastic reaction of short straight trough 7,1 generation of 8 pairs of conical pipes of the first straight trough for evenly offering the fracture of 6 pairs of conical pipes of long straight trough, 1 generation, simultaneously, the second connecting portion 12 can maintain the structural strength of conical pipe 1 tube wall again, make the elastic strength of conical pipe 1 whole all angles even, be further beneficial to solid pedicle nail 10 and in conical pipe 1, obtain stressed more uniformly
For the clamping force of further even 1 pair of solid pedicle nail 10 of conical pipe, the second straight trough 11 is between long straight trough 6 and short straight trough 7.
For ease of this guider, by exterior mechanical hands, clamped or hand-held, fixed handle 3 is a cross bar, and this cross bar is vertical with cylindrical channel pipe 2, and through hole 31 is opened in the middle part of cross bar.And in order to adapt to exterior mechanical hands, clamp this guider especially, make clamping action firm, cross bar also runs through and offers the both sides that two screwed holes, 32, two screwed holes 32 are symmetrically set in through hole 31, two screwed holes 32 can be spirally connected with the screw of exterior mechanical hands, realize dismountable firm connection.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit with this scope of this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to this utility model scope required for protection.
