Description
Technical field
The invention belongs to orthopedic medical devices, especially a kind of to need to be implanted into the orthopaedics used when broken bone or biomaterial
A kind of instrument, and in particular to the instrument used when being implanted into material for orthopaedics injecting type.
Background technology
Bone tissue or biomaterial are mainly moved on to skeleton defect, needs in patient body by operation and reinforce or melt by bone grafting operation
The position of conjunction.And in the course of surgery, often need by bone grafting instrument.
In field of orthopaedics, broken bone or biomaterial are implanted into caput femoris necrosis, bulk bone defect, vertebral body plastic operation etc.
It is played an increasingly important role in treatment.Broken bone, the packing materials such as bone cement, gel and calcium phosphate can be in part
Fixed, defect filling etc. plays key effect.In the orthopaedic disease such as treatment of caput femoris necrosis, bone tumour, often cut
Except pathological tissues, then need fill artificial material, play support, induction Bone Ingrowth the effects that, and the implantation amount of material whether
Functional rehabilitation that is accurate then affecting patient and prognosis.In centrum property disease, centrum often needs to inject the artificial materials such as bone cement
Material, with greater need for fine, the accurate implantation amount for controlling material.
And existing bone grafting apparatus mostly uses bone grafting pipe, implantation material, which is introduced defect, to play a supportive role, implantation amount
Bad appraisal, completely with the personal experience of doctor.Excessive or too small situation is measured in implantation frequent occurrence when operation, and then can be deposited
In some rehabilitations and more problem after.Therefore need one kind that can estimate required implantation quantity of material in advance, and can be more clear
The specific implantation quantity of material of understanding a kind of implantation instrument.And existing bone grafting pipe is non-telescoping, when bone grafting pipe is long or
All it is artificially to be pushed into or withdrawn from when too short, in due course would become hard to move when off size.
The purpose of the present invention is the orthopaedics implantation instruments for the prior art cannot be quantitative and how non-telescoping etc. well
Problem provides the instrument used when a kind of orthopaedics injecting type implantation material.
Invention content
For the problems such as overcoming the orthopaedics implantation instrument of the prior art cannot be quantitative and how non-telescoping well, the present invention
A kind of purpose instrument for using when being to provide orthopaedics injecting type implantation material that can be solved the above problems.
The purpose of the present invention is achieved through the following technical solutions：
The instrument used when a kind of orthopaedics injecting type implantation material comprising push rod sets bone cylinder, bone grafting end, and feature exists
In the bone cylinder of setting is connect with bone grafting end, and the push rod is set to described set in bone cylinder；Volume is surveyed in the setting of bone grafting end front end
Sacculus；The bone grafting end and set on bone cylinder inflatable structure of the setting to inflated；The detectable inflation of inflatable structure rear end connection
The air charging system of amount and inflation pressure.The setting of the inflatable structure of sacculus and rear end can be completed before bone grafting to the thick of bone grafting amount
Slightly estimate, Poor structure caused by preventing appraisal implantation excessive or very few.
Further, the sacculus can be set to bone grafting end front end by arbitrary mode, wherein it is preferred that passing through gluing
Mode is arranged in bone grafting end front end；Adhesive means can make sacculus be firmly fixed to bone grafting end front end.
Further, the inflatable structure is to be arranged at bone grafting end and set the gas tube on the inside of bone cylinder or be arranged at bone grafting end
And set filling channel in bone pipe wall.Wherein preferred embodiment is to be arranged at bone grafting end and set gas tube on the inside of bone cylinder.
Setting can make the telescopic segment that the elongation of bone grafting end is shortened on the bone grafting end, because telescopic segment, the inflatable structure is arranged
To be arranged at bone grafting end and setting gas tube on the inside of bone cylinder, and there are the parts stretched for telescopic segment in gas tube.Telescopic segment
The adjusting that may be implemented to bone grafting end length is set, it is easy to use, and extended by range and to shorten telescopic segment and may be implemented pair
Implantation material strikes real purpose.
Further, the bone grafting end is divide into upper part and lower part, and two parts have overlapped part, overlapped part
For telescopic segment.
Further, telescopic segment screw nut structure either mutual corresponding retaining structure or two is arranged in the telescopic segment
Spring structure is set between person.
Further, the retaining structure is to be arranged in the rule protrusion structure of bone grafting end top half and bone grafting end lower half
Divide corresponding rule sunk structure.
Further, telescopic segment and point between set bone canister portion setting tied for being controlled in the flexible connection of top control telescopic segment
Structure.The setting of connection control structure can ensure to be partially completed control to telescopic segment setting bone cylinder, easy to operate, be easy reality
It is existing.
Further, the connection control structure includes connecting the connection strap of telescopic segment and being arranged setting the holding by bone cylinder
Ring is held in ring, connection strap connection.
Further, the connection strap, which is fitted in, sets on the outside of bone cylinder and bone grafting end.
When the telescopic segment is set as retaining structure or spring structure, dashes forward setting setting termination below bone cylinder, prevent hand
Grip ring excessively moves down, and bone grafting end is made to detach up and down.Also set up side plate on the holding ring, for depressing and above put forward telescopic segment.
When the telescopic segment is set as screw nut structure, skid resistant course is set on the holding ring, preventing cannot effective band
Dynamic telescopic segment rotation.
Further, piston is set on the push rod；Or corresponding push rod screw nut knot is arranged with setting in push rod on bone cylinder
Structure.
Further, handle is set on the push rod, and the handle is set as crosswise.The setting of crosswise handle can be square
Convenient to operate and rotation
Further, scale is arranged on bone cylinder in described set.The setting of scale can facilitate understand bone grafting amount number.
Further, the bone cylinder of setting is connect with bone grafting end by streamline mode.Gradual mistake can be achieved in streamlined setting
Degree, prevents Caton phenomenon.
Further, the instrument material used when the injecting type implantation material is medical plastic material.It is wherein preferably saturating
Bright medical plastic material.
In use, first going deep at bone grafting end at bone grafting, tied if bone grafting end length can not enough be controlled by the connection of upper end
Structure stretches telescopic segment, after air bag is inflated by inflatable structure, after air bag full of behind entire bone grafting position, pass through upside
Inflatable structure understands aeration quantity, and further bone grafting amount needed for rough estimate；After deflate；Then by pushing or selecting
Push rod is pushed to by material is implanted into and need to fill position, and the required appraisal measured by scale and before understands filling situation, waits reaching
It is finely adjusted when to required bone amount.Device is removed out after the completion of bone grafting.
Compared with prior art, the instrument used when orthopaedics injecting type implantation material of the present invention is setting balloon structure, can
To carry out the rough estimate of implantation material, prevent implantation from estimating excessive or very few；The setting of telescopic segment can be effectively to not
Material implantation is carried out with depth bone grafting part.
