By mistake, the security of surgical procedure is improved.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, Fig. 1 is the main view cross-section structure of orthopaedics trepan instrument that the utility model embodiment provides
Schematic diagram, Fig. 2 are the left view structural representation for the orthopaedics trepan instrument that the utility model embodiment provides.
The embodiment of the utility model provides a kind of orthopaedics trepan instrument, including being equipped with 2 and second through hole 3 of first through hole
Sleeve 1, the axis of the axis of first through hole 2 and the second through hole 3 is parallel, and fixator is rotatably inserted in first through hole 2,
Trepan is fitted in second through hole 3.
During using orthopaedics trepan instrument provided by the utility model, fixator is fixed on the body of patient, specifically may be used
It is needed with being fixed on by the vertebra performed the operation, such as thoracic vertebrae and lumbar vertebrae, then inserts trepan in the second through hole 3, the second through hole 3 is around the
The axis of one through hole 2 rotates, until trepan alignment needs the position performed the operation, is performed the operation by trepan.It sets using the above structure
Meter so that orthopaedics trepan instrument can be stablized is fixed on the near sites for needing to perform the operation, logical by turnbarrel 1 second
Hole 3 is moved compared with first through hole 2, i.e., trepan is moved compared with fixator, and ensureing that trepan can be accurately aligned needs to perform the operation
Position, and can be changed around radius by the distance of the axis for changing 2 and second through hole 3 of first through hole, that is, realized pair
The control of cutting area.The tool construction is simple, easy to process and batch production, and fixed and adjustment is all extremely convenient, ensures
The security of operation.
In order to optimize the using effect of fixator in above-described embodiment, fixator includes being inserted in consolidating in first through hole 2
Fixed pole and the fixing piece being fixedly connected with patient body, fixed link are fixedly connected with fixing piece.It is preferred that fixator includes fixing
The fixed link and fixing piece of connection, fixed link facilitate installation into first through hole 2 and sleeve 1 are stablized easily around solid
Fixed pole rotates, and fixing piece can be in order to connecting with patient, such as fixing piece can preferably elastic band or latch closure belt etc..
In order to optimize the using effect of above-described embodiment middle sleeve 1, which further includes for by fixed link
The bolt being fixedly connected with sleeve 1, the periphery of first through hole 2 is equipped with and the pin hole of bolt cooperation.In specific implementation process, the
Two through holes 3 can be rotated around first through hole 2, when trepan moves to the position for needing to perform the operation, preferably by tightening bolt by sleeve 1
It is fixed compared with the orientation of fixed link, in case surgical procedure middle sleeve 1 occurs bounce and causes surgical error.
In order to optimize the using effect of fixed link in above-described embodiment, the both ends that fixed link is located at sleeve 1 are respectively equipped with
Limit protrusion, the spacing of limit protrusion are more than the length of sleeve 1.It is preferred that the both ends of fixed link are equipped with limit protrusion, sleeve 1 is avoided
It excessively freely moves along the axis direction of fixed link, is controlled by limiting sleeve 1 along the movement travel of fixed link axis direction
The position of sleeve 1, the straight skidding that sleeve 1 can be prevented excessive more avoid the possibility that sleeve 1 comes off from fixed link.
It is understood that the length that sleeve 1 is located at the one side of the second through hole 3 is less than positioned at the one side of first through hole 2
Length, the bottom that sleeve 1 is located at the second through hole 3 are equipped with inclined end face.Due to the second through hole 3 for inserting trepan, in order to avoid
Sleeve 1 is located at rotation and the length feed of the bottom obstruction trepan of the second through hole 3, and bottom is equipped with inclined end face preferably at this,
The rotation of more convenient trepan.
In another specific embodiment, which further includes fixed link being pressed in first through hole 2
The bolt on surface, the periphery of first through hole 2 are equipped with bolt hole.In addition to the mode of above-mentioned bolt positioning, can also preferably it pass through
Bolt fixes sleeve 1 after trepan is turned to wait the position performed the operation, tightens bolt and set can be realized compared with the orientation of fixed link
The fixation of cylinder 1.Using the fixed form of bolt, pin hole processing is both needed on sleeve 1 and fixed link, also needs to process in fixed link
The pin hole being distributed along different radii, and special processing, the end of bolt then need not be done in fixed link using the mode that bolt positions
The inner surface of first through hole 2 can be pressed in by pushing against fixed link.Certainly, as long as can play 1 orientation of sleeve is fixed
