Description
Technical field
The utility model is related to medical instruments field, especially a kind of bone grafting assistor.
Background technology
Today's society, the fracture caused by traffic accident, tumble injury is more and more, and people can not be satisfied with manipulative reduction in the past
Again with the outer fixed operation of clamping plate or plaster fixing, but the open reduction operation for being capable of anatomical reduction is more have selected, with
And come be implantation internal fixation material (such as steel plate, screw, hollow nail etc.) afterwards, it is necessary to secondary operate on, take out internal fixation material.
The bone for eliminating internal fixation material has been left with the cavity of original oncomelania nail, for the healing of later stage marrow, the stabilization of bone
All there is certain drawback.Surgical doctor can be implanted into granular artifical bone in screw hole, for filling hole, but need operation
Doctor grips one with vessel forceps, and one is filled toward screw hole, because screw hole is deeper, perienchyma's extruding, past in bone grafting way
It is past to waste time and energy, and artificial bone loss is more.
A kind of intervertebral bone grafting apparatus and Patent No. CN disclosed in the U of Patent No. CN 201701281 patent
On filler tube below interbody bone graft device two-piece-dress disclosed in 202078378 U patent, the funnel of above two bone grafting instrument
Scale is not provided with, the consumption for being implanted into broken bone can not be held by using, it is easy to which making the consumption of the broken bone of implantation excessively causes
Waste or the implantation very few influence therapeutic effect of consumption, be also unfavorable for recording usage amount, it is impossible to provide for follow-up implantation consumption
It can be seen that foundation.Also handle is not provided with funnel, uses and has many inconvenience, is existed in the stability for keeping bone grafting instrument
Defect.
Utility model content
For existing problem more than solving, the utility model discloses a kind of bone grafting assistor.
A kind of bone grafting assistor, including funnel include infundibular body, the infundibular body top half side with bar, the funnel is disclosed
Face and horizontal plane angle lower half point side and horizontal plane angle are big, and the infundibular body top half is fixed close to top one end
Handle is connected, the handle has with horizontal plane is fixedly connected with filler tube, the filler tube below certain angle, the infundibular body
Some graduation marks are marked with, the bar of disclosing is a handled cylindric strip in top, and its diameter is slightly less than funnel bore.
Further, maximum scale is at least 80mm on a diameter of 5mm of the filler tube, the filler tube, wherein minimum
Scale unit is 1mm.It so can be very good to record and control the usage amount for being implanted into broken bone, reduce the loss of artificial bone.
Further, the infundibular body top half length is 20mm, a length of 30mm in the latter half, and back cut diameter is
90mm, lower port diameter is 5mm, and infundibular body top half side and horizontal plane angle are 30-40 °, the latter half side with
Horizontal plane angle is 65-75 °, and the funnel length of tube is 85-100mm.Because the relative aperture of funnel top half is larger, so
What can be trusted when in use is put into broken bone, reduces the possibility that drops during bone grafting.
Further, the handle and horizontal line angle are 9-12 °.So effectively bone grafting can be kept auxiliary when in use
Help the stability of device, it is not easy to produce inclination.
Further, the bar length of disclosing is 180mm-200mm, and a diameter of 4.5mm, the handle is 40mm-60mm.This
Sample can keep disclosing fitting for bar and funnel inside pipe wall, facilitate the compression of broken bone, it is ensured that bone grafting quality.
Beneficial effect：
The utility model is provided with scale on funnel tube wall, can be very good to hold the consumption of the broken bone of implantation, is also convenient for note
Usage amount is recorded, visible foundation can be provided for follow-up implantation consumption, funnel is provided with handle, in use can be good
Keep the stability of bone grafting instrument, also effectively reduce the loss of artificial bone, shorten the time of the manpower bone establishes a bone, improve perform the operation into
Journey, reduces the probability of postoperative infection.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the utility model overlooking the structure diagram；
Fig. 3 is that the utility model discloses bar structural representation.
Wherein, 1 is handle, and 2 be infundibular body, and 3 be filler tube, and 4 is disclose bar, and 401 be handle.
Embodiment
With reference to accompanying drawing, the utility model is described in further details：
As shown in drawings, a kind of bone grafting assistor, including funnel include infundibular body 2, the leakage with bar 4, the funnel is disclosed
The top half of bucket body 2 side and horizontal plane angle lower half point side and horizontal plane angle are big, the top half of infundibular body 2
Handle 1 is fixedly connected with close to top one end, the handle 1 has certain angle with horizontal plane, and the lower section of infundibular body 2 is fixed to be connected
Filler tube 3 is connect, the filler tube 3 is marked with some graduation marks, and the bar 4 of disclosing has the cylindric length of handle 401 for a top
Bar, its diameter is slightly less than the internal diameter of filler tube 3.Maximum scale is at least on a diameter of 5mm of the filler tube 3, the filler tube 3
80mm, wherein minimum scale unit are 1mm, so can be very good to record and control the usage amount for being implanted into broken bone, are reduced artificial
