Abstract
The utility model discloses an intervertebral bone grafting apparatus, which comprises a funnel and a stamp stem. The funnel comprises a funnel body (1) and a guide sleeve (2), the diameter of an upper opening of the funnel body (1) is 3.5-5cm, the diameter of a lower opening of the funnel body (1) is 8-10mm, an included angle between an inclined face of the funnel body (1) and the horizontal plane is 30-45 degrees, the guide sleeve (2) is a hollow cylinder with a 12-15cm length, the stamp stem includes a stem body (4) and a handle (3), and the stem body (4) is a solid cylinder tightly matched with the inner wall of the guide sleeve (2) in a vertical sliding manner. The intervertebral bone grafting apparatus greatly facilitates surgical operation, is fast in bone graft, saves surgical time, avoids repeated stimulation and damage to spinal nerves due to the fact that the bone grafting is finished inside the guide sleeve, reduces postoperative complications, can accurately convey grafting materials to a required position, guarantees sufficient grafting, increases intervertebral fusion rate, and increases postoperative spinal stability.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of intervertebral bone grafting device.
Background technology
In spinal operation,, be expert at the fixed while of pedicle nail bar system usually capable intervertebral bone graft fusion in order to increase the stability of spinal column.The desirable Invasive lumbar fusion device of intervertebral bone-graft fusion material, from body bone and homogeneous allogenic bone because Invasive lumbar fusion device costs an arm and a leg, the homogeneous allogenic bone rejection is many, so a lot of patient requires selection to take from the body bone as this material of bone grafting.Mainly contain spinous process and the vertebral plate bone that excises in autologous ilium and the art from the body bone, how these bone-grafting materials are put into the bone grafting position? usually all be after knowing intervertebral vertebral pulp and cartilaginous lamina tissue, with vascular forceps clamp ground of the broken bone of fritter from about fill in the intervertebral space, operate very inconvenient, speed is slow, length consuming time; And also need in the art dura mater and nerve root are retracted to make things convenient for bone grafting, might cause spinoneural damage again in its process.Owing in intervertebral bone grafting process at ordinary times, usually be difficult for controlling, so this utility model provides a kind of bone grafting device of simply and easily bone-grafting material being delivered to intervertebral.
Summary of the invention
The purpose of this utility model is to provide a kind of intervertebral bone grafting device in order to overcome above-mentioned weak point.
This purpose is implemented in the following manner:
A kind of intervertebral bone grafting device, it is characterized in that this intervertebral bone grafting device comprises funnel and stamp stem, described funnel comprises bucket body 1 and guide pin bushing 2 two parts, and bucket body 1 back cut diameter is 3.5-5cm, bucket body 1 lower port diameter is 8-10mm, and the angle of bucket body 1 inclined-plane and horizontal plane is 30-45 °; Guide pin bushing 2 is hollow cylinder, and long is 12-15cm; Stamp stem comprises shaft 4 and handle 3, and shaft 4 is a solid cylinder, is fitted close to guide pin bushing 2 inwalls of funnel to slide up and down.The shaft 4 of stamp stem is than the long 5-8cm of funnel, and instrumentarium adopts stainless steel material to make.
The beneficial effects of the utility model compared with the prior art:
This intervertebral bone grafting device is very easy to operation technique, and practical, bone grafting speed is fast, has saved operating time, and the bone grafting process is finished in the guide pin bushing tube simultaneously, has avoided spinoneural repetitious stimulation and damage, reduces post-operative complication.And can accurately bone-grafting material be delivered to desired location with this intervertebral bone grafting device, make bone grafting amount abundance, increase the intervertebral fusion rate, improve the postoperative spinal stability.
Description of drawings
Fig. 1 is the sketch map of intervertebral bone grafting device.
Among the figure, a is a funnel, and b is 1 for stamp stem, and wherein, 1 is bucket body, and 2 is guide pin bushing, and 3 is handle, and 4 is shaft.
The specific embodiment
A kind of intervertebral bone grafting device, this intervertebral bone grafting device comprises funnel and stamp stem, and described funnel comprises bucket body 1 and guide pin bushing 2 two parts, and bucket body 1 back cut diameter is 3.5-5cm, and bucket body 1 lower port diameter is 8-10mm, the angle angle of bucket body 1 inclined-plane and horizontal plane is 30-45 °; Guide pin bushing 2 is hollow cylinder, long is 12-15cm, and stamp stem bag shaft 4 and handle 3, shaft 4 are solid cylinder, is fitted close to guide pin bushing 2 inwalls of funnel to slide up and down.The shaft 4 of stamp stem is than the long 5-8cm of funnel, and instrumentarium adopts stainless steel material to make.As shown in Figure 1.
The concrete operations mode:
At first in the guide pin bushing 2 terminal insertion one side intervertebral spaces with intervertebral bone grafting device, one assistant is holding up and is holding bucket body 1, the patient pours little broken bone piece in the bucket body 1 of funnel into, the reuse handle of holding stamp stem 3 of internal diameter coupling with it pushes to the intervertebral desired location by shaft 4 with broken bone, and available stamp stem pressurizes to broken bone, make bone grafting solid reliable, again to finish the bone grafting of opposite side with method.And in the bone grafting process,, need not tractive dura mater and nerve root because of in guide pin bushing 2, finishing.
