Description

A kind of bone grafting device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates to a kind of bone grafting device particularly.

Background technology

In bone surgery, when the patient needed bone grafting because of bone loss or necrosis, method in the past was that operative doctor punches at skeleton, will from the hole, put into from body skeleton or grain of bone cement with operating forceps then.This method operating time is long, increases patient's misery, and the bone density of implanting also is difficult to guarantee.

To this problem, existing at present multiple intervertebral bone grafting device, it mainly comprises an infundibular body and a guide rod, and described infundibular body comprises a funnel and a hollow cylinder, and funnel is installed on cylindrical end.During use, the ossiculum piece is poured in the funnel, and then with guide rod broken bone is pushed to desired location through cylinder and get final product.

This device has improved bone grafting efficient, yet, the weak point below still existing: because behind ossiculum piece of every propelling movement; Just need guide rod be withdrawed from funnel, reappose another ossiculum piece again, guide rod is aimed at funnel more again and is pushed; Efficient is still not high like this, is unfavorable for saving operating time.

The utility model content

The purpose of this utility model is to provide a kind of novel bone grafting device, to solve the problems referred to above that exist in the prior art.

The technical scheme that this utility model provides is following:

A kind of bone grafting device is characterized in that, comprising:

One sleeve pipe, a connector is established in said sleeve pipe side;

One funnel is located at said telescopic side, and is communicated with lateral connector; And

One guide rod, it comprises that one can insert a telescopic end along telescopic axial direction, and from the bar portion that the other end passes, the length of this bar portion is greater than telescopic length.

In the preferred embodiment of this utility model, be fixed connection or detachable connection between described funnel and the said sleeve pipe.

In the preferred embodiment of this utility model, the angle between the axis of described funnel and the said telescopic axis is the 0-90 degree.

More preferably, the angle between the axis of described funnel and the said telescopic axis is 30 degree, 45 degree, 60 degree or 90 degree.

In the preferred embodiment of this utility model, connect through a connection tube between described funnel and the said telescopic connector.

In the preferred embodiment of this utility model, the bar portion diameter of said guide rod is the 1/3-4/5 of casing inner diameter, and the end of this bar portion is provided with the end that upwards expand in a footpath.

In the preferred embodiment of this utility model, this end of expanding also is provided with the coronal front end of a ball.

In the preferred embodiment of this utility model, described telescopic connector is located at the wherein 1/3-1/5 cylinder length place of an end of distance.

The advantage of this utility model is following: when 1, operating, can little skeletal grain be put into funnel and get into cylinder intracavity, push desired location with guide rod afterwards; When withdrawing from, because funnel is located at telescopic side, so guide rod need not from sleeve pipe from withdrawing from fully; Can in funnel, put down a little skeletal grain; Thus, made things convenient for operation, and dress grain speed is greatly improved.2, this funnel can be made as different angles, is fit to different places and uses; This connection tube can be flexible pipe, and is more convenient to the angular adjustment of funnel.3, the bar portion of guide rod can be made as common cylinder, or bar portion dwindles, and expand the end, can improve the range of activity of bar portion like this, is beneficial to compression and gets into the skeletal grain in the skeleton, to improve bone density.

The specific embodiment

Embodiment one

See figures.1.and.2, a kind of bone grafting device is made up of sleeve pipe 1, funnel 2 and guide rod 3.

Sleeve pipe 1 comprises main body 11 and connector 12, and this main body 11 is an open column shape, and connector 12 is located at the about 1/4 total length place of main body 11 left ends, and the axis direction of this connector 12 is vertical with the axis direction of cylinder 11.

The lower end of funnel 2 is provided with the end 21 that cooperates with the connector of sleeve pipe 1 12, and during use, the connector 12 that sleeve pipes 1 are inserted in the end 21 of funnel 2 get final product, and this moment, axis and the angle between the said telescopic axis of funnel were 90 to spend.When not using, can funnel 2 and sleeve pipe be left in 1 minute, can reduce the space like this, convenient collection.

Guide rod 3 comprises an one handle 33 and a bar portion 31, also is provided with a limiting section 32 between this handle 33 and the bar portion 31.This bar portion 31 is the cylinder bodily form, and diameter is slightly less than the internal diameter of sleeve pipe 1, and the diameter of limiting section 32 is then greater than the external diameter of sleeve pipe 1; And have certain-length,, can avoid bar portion 31 too to stretch in the bone like this like 3-5cm; And can avoid finger to be sandwiched between handle 33 and the sleeve pipe 1 handled easily.

Embodiment two

Referring to Fig. 3 and Fig. 4; The basic structure of present embodiment is identical with embodiment one, and different is that the angle a between the axis of the connector 12 of sleeve pipe 1 and the axis of main body 11 is 60 degree; When funnel 2 inserted like this, the angle between the axis of the axis of funnel 2 and sleeve pipe 1 also was 60 degree.

Embodiment three

Referring to Fig. 5; The basic structure of present embodiment is identical with embodiment two, and different is to be provided with a connection tube 4 between the connector 12 of sleeve pipe 1 and the end 21 of funnel 2; This connection tube 4 can be the flexible pipe with certain deformability, for example the moderate rubber tube of hardness.Funnel 2 adjustable-angles can not diminish because of the excessive deformation diameter again in the pipe simultaneously like this.

Embodiment four

Referring to Fig. 6; Basic structure of this utility model and embodiment one, two or three are basic identical, and different is that the diameter of the bar portion 31 of guide rod 3 is less than the bar portion diameter of front embodiment; In the present embodiment; Its diameter is about 2/3 of sleeve pipe 1 internal diameter, and expand with respect to bar portion 31 end 311, but still is slightly less than the internal diameter of sleeve pipe 1.Because the diameter of bar portion 31 is little, so the range of activity of end 311 is big, can strengthen getting into the skeletal grain extruding in the skeleton.

Embodiment five

Referring to Fig. 7, basic structure of this utility model and embodiment four are basic identical, and different is, the bar portion of guide rod 3, and its end 311 also is provided with the coronal front end 312 of a ball.312 pairs of skeletal grain squeezing effects that got in the skeleton of the coronal front end of this ball are better.

The above-mentioned specific embodiment that is merely this utility model, but the design concept of this utility model is not limited thereto allly utilizes this design that this utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading this utility model protection domain.
