Description
Technical field
The present invention relates to medical instruments fields, more particularly to a kind of disposable drainage type vertebral pedicle puncture external member.
Background technology
Bone cement is a kind of for filling bone with implantation material gap or bone cavity and with the biomaterial of self-solidifying characteristic.Since
Since Charney first Application cement reaction femoral prosthesis successfully implements total hip replacement within 1958, bone cement oneself extensively
Applied to Orthopedic Clinical, cement reaction can guarantee the instant stabilization of postoperative prosthese, and early postoperation is allowed to bear a heavy burden, curative effect affirmative.
Pedicle of vertebral arch is a part for vertebral arch, arises from centrum upper back, short and thick, rearward protrusion vertical with centrum direction,
Its shape is in arc.When fixing centrum using the reparation of bone cement pedicle, need advanced pedicle of vertebral arch of passing through will be in centrum
The suction of portion oozing of blood, but oozing of blood is difficult to drain net, especially during bone cement push, the time is up to several minutes, this
It is the effective suction that can not carry out oozing of blood in several minutes, a large amount of hematocele is obviously easy to influence the effect of operation, leads to bone cement
It is poor with the conjugation of centrum sclerotin, it needs to improve.
Invention content
It is convenient in bone the invention mainly solves the technical problem of providing a kind of disposable drainage type vertebral pedicle puncture external member
The suction that oozing of blood in centrum is carried out during cement push reduces the influence that hematocele combines bone cement with centrum sclerotin.
In order to solve the above technical problems, one aspect of the present invention is：A kind of disposable drainage type vertebra is provided
Nut puncturing kit, including：Working column, bone cement storage tube and push rod, be axially provided with partition board in the working column and
Working column endoporus is divided into drainage lumens and bone cement storage tube directed cavity, the bone cement storage tube passes through bone cement storage tube
Directed cavity and extend to its rear end from working column front end, the push rod is arranged in bone cement storage tube, the working column
It is provided with drainage tube joint outside front end, facilitates external vacuum suction, the drainage tube joint to be connected with drainage lumens, the work
Make casing front end to be provided with arc panel and block drainage lumens.
In a preferred embodiment of the present invention, it is respectively arranged in the outer circle of the working column and bone cement storage tube
Scale.
In a preferred embodiment of the present invention, the working column front end is provided with first handle, the first handle
On be provided with the first hole passed through for bone cement storage tube.
In a preferred embodiment of the present invention, bone cement storage tube front end is provided with second handle, and described second
The second hole passed through for push rod is provided on handle.
In a preferred embodiment of the present invention, the bone cement storage tube directed cavity, bone cement storage tube and push rod
Section is respectively D-shaped.
In a preferred embodiment of the present invention, the working column is stainless steel tube or plastic tube..
In a preferred embodiment of the present invention, the push rod front end is provided with third handle.
The beneficial effects of the invention are as follows：A kind of disposable drainage type vertebral pedicle puncture external member that the present invention points out, work set
Pipe pedicle reaches inside centrum, first with the external leather hose of drainage tube joint and syringe, the extraction of oozing of blood is carried out, then dress
There is the bone cement storage tube of bone cement to be inserted into working column, and extend to from working column end and to need to fill position, then
Push rod is inserted into bone cement storage tube and carries out the push of bone cement, while continuing the extraction of oozing of blood, until bone cement has pushed
At greatly reducing the influence that watery blood combines bone cement with centrum sclerotin, improve the knot that bone cement is combined with centrum sclerotin
Close effect.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, wherein：
Fig. 1 is a kind of structural schematic diagram of disposable one preferred embodiment of drainage type vertebral pedicle puncture external member of the present invention；
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
~ Fig. 2 is please referred to Fig.1, the embodiment of the present invention includes：
A kind of disposable drainage type vertebral pedicle puncture external member, including：Working column 1, bone cement storage tube 2 and push rod 3, the work
Make axially to be provided with partition board 8 in casing 1 and 1 endoporus of working column is divided into drainage lumens 9 and bone cement storage tube directed cavity 10, institute
It states bone cement storage tube 2 and extends to its rear end, the push rod from 1 front end of working column by bone cement storage tube directed cavity 10
