The specific embodiment
Core of the present utility model provides a kind of Kirschner wire guider, and this Kirschner wire guider makes the success rate of Kirschner wire fixing operation higher.
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1-Fig. 6, in a kind of specific embodiment, a kind of Kirschner wire guider that this utility model provides, the Kirschner wire guider that this utility model provides, comprise connector 1, fixture block 2, slip fixture block 3, at least one inner sleeve 4 and two outer sleeves 5, fixture block 2 and slip fixture block 3 are installed in the same side of connector 1, two outer sleeves 5 are installed in respectively on fixture block 2 and the slip fixture block 3, inner sleeve 4 is installed in the wherein inside of at least one of two outer sleeves 5, the internal diameter of inner sleeve 4 is more than or equal to the external diameter of Kirschner wire 7, inner sleeve 4 is provided with locating part 6, and locating part 6 is between fixture block 2 and slip fixture block 3.Can in two outer sleeves 5 of Kirschner wire guider, inner sleeve 4 be set all, also can in an outer sleeve inner sleeve 4 be set therein separately.Connector 1 can be round bar or straight plate.When the locating part 6 on the inner sleeve 4 made fixture block 2 and slip fixture block 3 clamp skeleton 8, inner sleeve 4 is outer sleeve 5 slips relatively not, play the location.Locating part 6 can be for being sheathed on the spacing ring on the inner sleeve 4, also can be for being welded on the spacing preiection on the inner sleeve 4.
When carrying out the Kirschner wire fixing operation, the fixture block 2 of Kirschner wire guider is blocked skeleton 8 with slip fixture block 3 makes inner sleeve 4 relative skeletons 8 according to predetermined angular and fixed-site, the Kirschner wire 7 that an end is arranged on the electric drill passes inner sleeve 4 then, then Kirschner wire 7 is squeezed in the skeleton 8, after operation finishes, slip fixture block 3 or fixture block 2 drive inner sleeve 4 and remove, and carry out subsequent treatment again.
In the Kirschner wire guider that this utility model embodiment provides, inner sleeve 4 can be Kirschner wire 7 guiding, the angle of Kirschner wire 7 can not changed, mobile fixture block 2 and slip fixture block 3 can be stuck in inner sleeve skeleton 8 places, the position of inner sleeve 4 can be offset, thereby Kirschner wire 7 is squeezed in the skeleton 8 according to predetermined angular and position, improved the success rate of Kirschner wire fixing operation.
This Kirschner wire guider can be more convenient undergo surgery for patella 801, tibial plateau 802 and palm or phalanx bone 803, same this device also can be applicable to the operation of skeletons such as wrist navicular bone, distal radius, squeezes into angle and position and can determine according to corresponding Therapeutic Method.
In the Kirschner wire guider that this utility model one embodiment provides, in the outer sleeve 5 on fixture block 2 and the slip fixture block 3 inner sleeve 4 is set all, make two inner sleeves 4 all replaceable, can be according to the position of Kirschner wire guider, can squeeze into Kirschner wire 7 by the inner sleeve 4 on the fixture block 2, also can squeeze into Kirschner wire 7 by the inner sleeve 4 on the slip fixture block 3, make the mode of operation more flexible and changeable; Owing to be provided with inner sleeve 4 in the outer sleeve 5 on fixture block 2 and the slip fixture block 3, in the process of Kirschner wire fixing operation, that can observe Kirschner wire 7 easily makes pin position and direction in advance, makes operation more accurate.
In order to protect the soft tissue in affected part, one of them that is provided with 4, two inner sleeves 4 of inner sleeve in two outer sleeves 5 is equipped with soft tissue baffle plate 10.In some Kirschner wire fixing operations, Kirschner wire goes out pin mark place sclerotin and need not to expose (namely this place's soft tissue need not to peel off), can go out pin mark place application soft tissue baffle plate 10.
Soft tissue baffle plate 10 not only can make the Kirschner wire guider better locate, and makes the patient more comfortable, has avoided the secondary injury to the affected part.In order to make soft tissue baffle plate 10 more reliable being fixed on the inner sleeve 4, soft tissue baffle plate 10 and inner sleeve 4 ball-joints.Ball-joint makes soft tissue baffle plate 10 bigger with respect to the angle that inner sleeve 4 rotates, and makes soft tissue baffle plate 10 more flexible, makes surgical effect better.
Further, outer sleeve 5 and locating part 6 clampings.In operation, because Kirschner wire 7 is squeezed in the skeleton 8 by inner sleeve 4 by electric drill, electric drill drives Kirschner wire 7 and rotates, Kirschner wire 7 might drive inner sleeve 4 and rotate, thereby cause the secondary injury in affected part, and outer sleeve 5 and locating part 6 clampings, because locating part 6 is fixed on the inner sleeve 4, thereby make inner sleeve 4 not relatively outer sleeve rotate, ensured the safety of operation.
Further, locating part 6 is positioned at the middle part of inner sleeve 4, when locating part 6 is positioned at inner sleeve 4 middle parts, make inner sleeve 4 moderate apart from the distance of outer sleeve 5, make an end of inner sleeve 4 can pass soft tissue and prop up skeleton 8, the external diameter of inner sleeve 4 is littler than the external diameter of locating part 6, inner sleeve 4 external diameters are less, injury to soft tissue is less, make the wound in affected part less, thereby the wound healing time is shorter.
Preferably, the connector 1 of Kirschner wire guider is rule.Rule makes the Kirschner wire guider have measurement function, before blocking skeleton 8, chucking fixture block 2 and slip fixture block 3, read original reading A, block skeleton 8 then, read reading B, reading B deducts the maximum depth of needle C that reading A is skeleton 8, judge the length that Kirschner wire 7 needs are squeezed into according to C, make operation more accurate, further improved the success rate of operation.
Preferred, slip fixture block 3 is set with hold-down nut 9 with the junction of rule.When operation, after slip fixture block 3 and fixture block 2 block skeleton 8 and position and angle and determine, tighten hold-down nut 9 and make slip fixture block 3 relative with the position of rule more stable, make the Kirschner wire guider be difficult for relative slip takes place with skeleton 8, further ensured the safety of operation.
This installs the material that all parts adopt all can carry out sterilization treatment, the conventional high pressure steam sterilization that adopts, and sterilising conditions requires: steam pressure 205.8kPa, temperature reaches more than 132 ℃ and kept 10 minutes.
More than Kirschner wire guider provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from this utility model principle, can also carry out some improvement and modification to this utility model, these improvement and modification also fall in the protection domain of this utility model claim.
