Abstract
The utility model discloses a kind of intervertebral bone graft former, including pressing plate and shaping box, described pressing plate front end and the front end of shaping box pass through hinge chain connection, forming tank is provided with shaping box, two pieces of demarcation strips are provided with forming tank, chute is provided with the both sides of forming tank, lock-screw is connected after passing through chute with the end thread of demarcation strip.The utility model can need to adjust the plant bone mass size after bone grafting amount and shaping according to operation, realize the accurate measurement bone grafting volume in surgical procedure, change the present situation for empirically determining bone grafting amount, be conducive to formulating rational operation technique specification, improve surgical effect.Therefore, the utility model is not only simple in structure, easy to operate, practical, and the plant bone mass crushing resistance of shaping is strong, and healing rate is high, greatly reduces surgery cost, in the Intervertebral disc fusion operation that can be widely applied to hospital.
Description
Technical field
The utility model is related to a kind of intervertebral bone graft former, belongs to technical field of medical instruments.
Background technology
Many spinal surgeries often need pedicle screw to fix and posterior decompression bone grafting, need suffering from surgical procedure
Person's lesion inserts pedicle screw above and below gap, cuts upper section pyramidal portion inferior articular process according to spinal canal stenosis situation, then
Chisel takes patient's ilium, and ilium chisel takes bulk and the broken bone of fritter appropriate, bone grafting fusion is carried out therewith.In above-mentioned surgical procedure, by
The bone piece shape, not of uniform size taken in chisel, it is difficult to quantitative determine, therefore all the time, implantation bone amount number be according to doctor
Raw is empirically determined.Due to lacking accurate quantitative criteria, feasibility and validity effect for operation judge exist necessarily
Blindness.
Utility model content
The purpose of this utility model is that there is provided a kind of simple in construction, easy to use, bone grafting amount is controllable, bone grafting block size
Adjustable intervertebral bone graft former, to overcome deficiency of the prior art.
The technical solution of the utility model：Before a kind of intervertebral bone graft former, including pressing plate and shaping box, described pressing plate
End and the front end of shaping box are provided with forming tank on shaping box, two pieces are provided with forming tank by hinge chain connection
Demarcation strip, chute is provided with the both sides of forming tank, and lock-screw is connected after passing through chute with the end thread of demarcation strip.
The direction of chute is provided with graduation mark on the outer wall of the forming tank.
Described pressing back-end and the rear end of shaping box are provided with handle.
The length of the chute is equal to the length of forming tank.
Due to using above-mentioned technical proposal, the utility model has the advantage of：The utility model can need to adjust according to operation
Plant bone mass size after whole bone grafting amount and shaping, realizes the accurate measurement bone grafting volume in surgical procedure, changes foundation
The present situation of empirically determined bone grafting amount, is conducive to formulating rational operation technique specification, improves surgical effect.Therefore, this practicality is new
Type is not only simple in structure, easy to operate, practical, and the plant bone mass crushing resistance of shaping is strong, and healing rate is high, greatly reduces
Surgery cost, in the Intervertebral disc fusion operation that can be widely applied to hospital.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals：1- pressing plates, 2- hinges, 3- shaping box, 4- graduation marks, 5- chutes, 6- lock-screws, 7- separates
Plate, 8- forming tanks, 9- handles.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are clearer, it is right with reference to the accompanying drawings and examples
The utility model is described in further detail.
Embodiment of the present utility model：The structural representation of intervertebral bone graft former as shown in figure 1, including pressing plate 1 and into
Flask 3, handle 9 is provided with the rear end of the rear end of pressing plate 1 and shaping box 3, and the front end of pressing plate 1 and the front end of shaping box 3 pass through
The chain connection of hinge 2, is provided with forming tank 8 on shaping box 3, two pieces of demarcation strips 7 is provided with forming tank 8, in forming tank 8
Both sides be provided with chute 5, and the length of chute 5 is equal to the length of forming tank 8；Lock-screw 6 pass through chute 5 after with demarcation strip
7 end thread connection.Meanwhile, the direction of chute 5 is provided with graduation mark 4 on the outer wall of forming tank 8, therefore, can root
Position of two pieces of demarcation strips 7 on graduation mark 4 is adjusted according to the plant bone mass size after the bone grafting amount needed for operation and shaping
Put, so as to obtain various sizes of plant bone mass.
