Description
Technical field
The utility model belongs to orthopedic medical device, particularly a kind of to need to be implanted into the orthopaedics device used during biomaterial
Tool, and in particular to be a kind of novel bone grafting apparatus.
Background technology
In field of orthopaedics, implantation people's bone or biomaterial are in caput femoris necrosis, bulk Cranial defect, vertebral body plastic operation etc.
More and more important role is play in treatment.Broken bone, the packing material such as bone cement, gel and calcium phosphate, can be in part
Key effect is played in terms of fixed, defect filling.In the orthopaedic disease such as treatment of caput femoris necrosis, bone tumour, often cut
Except pathological tissues, then need to fill broken bone or artificial material, play support, induction Bone Ingrowth etc. and act on, and the plant of material
Enter whether accurate functional rehabilitation and the prognosis for then affecting patient of amount.In centrum property disease, centrum often needs to inject bone cement
Deng artificial material, with greater need for fine, the accurate implantation amount for controlling material.
And bone grafting pipe is used existing bone grafting apparatus more, implantation material is introduced into defect plays a supportive role, implantation amount
Bad appraisal, the completely personal experience with doctor.Implantation amount excessive or too small situation often occurs during operation, Post operation is past
It is past to there are some side effects or there is the problem of rehabilitation efficacy is not good.Therefore one kind is needed to estimate required implantation material in advance
Amount, and can more be apparent from a kind of implantation instrument of specific implantation quantity of material.Other existing bone grafting pipe can not be stretched
Contracting, is all artificially to be pushed into or withdrawn from when bone grafting pipe is long or too short, would become hard to move in good time when off size
It is dynamic.
The purpose of this utility model is that the orthopaedics implantation instrument for being directed to prior art can not well be quantified and can not stretched more
The problems such as contracting, there is provided a kind of novel bone grafting apparatus.
Utility model content
Can not be quantitative and how non-telescoping well for the orthopaedics implantation instrument for overcoming prior art the problems such as, this practicality
New purpose is to provide a kind of novel bone grafting apparatus that can be solved the above problems.
The purpose of this utility model is achieved through the following technical solutions：
A kind of novel bone grafting apparatus, it includes push rod, puts bone cylinder, bone grafting end, it is characterised in that described to put bone cylinder and bone grafting
End connection, the push rod is arranged at described put in bone cylinder；Bone grafting end front end, which is set, surveys volume sacculus；The bone grafting end and put
Inflatable structure to inflated is set on bone cylinder；The detectable aeration quantity of inflatable structure rear end connection and the inflation dress for inflating pressure
Put.The setting of the inflatable structure of sacculus and rear end can complete the rough estimate to bone grafting amount before bone grafting, prevent bone amount to be implanted into
The excessive or very few Poor structure caused.
Further, the sacculus can be arranged at bone grafting end front end by arbitrary mode, wherein it is preferred that by gluing
Mode is arranged on 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 on bone grafting end and put the gas tube on the inside of bone cylinder or be arranged on bone grafting end
And put filling channel in bone pipe wall.Wherein preferred embodiment is the gas tube for being arranged on bone grafting end and putting on the inside of bone cylinder.
The telescopic section that can shorten the elongation of bone grafting end is set on the bone grafting end, because setting telescopic section, the inflatable structure
To be arranged on bone grafting end and putting the gas tube on the inside of bone cylinder, and the part stretched for telescopic section is left in gas tube.
Further, the bone grafting end be divided into above and below two parts, two parts have overlapped part, overlapped part
For telescopic section.
Further, the telescopic section sets telescopic section screw nut structure either mutual corresponding retaining structure or two
Spring structure is set between person.
Further, the retaining structure is that the rule for being arranged on bone grafting end top half protrudes structure and bone grafting end lower half
Divide corresponding rule sunk structure.
Further, telescopic section and put and be provided for controlling the flexible connection of telescopic section to control to tie on top between bone cylinder part
Structure.Settings of connection control structure can ensure to be partially completed control to telescopic section putting bone cylinder, simple to operate, easily reality
It is existing.
Further, the connection control structure includes the connection strap of connection telescopic section and is arranged on to put the other holding of bone cylinder
Ring is held in ring, connection strap connection.
Further, the connection strap, which is fitted in, puts on the outside of bone cylinder and bone grafting end.
When the telescopic section is set to retaining structure or spring structure, is dashed forward putting to set to terminate below bone cylinder, prevent hand
Hold ring excessively to move down, make to separate above and below bone grafting end.Also set up side plate on the holding ring, for depressing and above put forward telescopic section.
When the telescopic section is set to screw nut structure, skid resistant course is set on the holding ring, preventing can not effective band
Dynamic telescopic section is rotated.
Further, piston is set on the push rod；Or push rod sets corresponding push rod screw nut knot with bone grafting cylinder
Structure.
Further, handle is set on the push rod, and the handle is set to crosswise.The setting of crosswise handle can be square
Convenient to operate and rotation
Further, described put sets scale on bone cylinder.Scale set can conveniently understand bone grafting amount number.
Further, the bone cylinder of putting is connected with bone grafting end by streamline mode.Gradual mistake can be achieved in streamlined set
Degree, prevents Caton phenomenon.
Further, the novel bone grafting apparatus material is medical plastic material.Wherein it is preferably transparent medical grade plastic material.
In use, first bone grafting end is goed deep at bone grafting, if bone grafting end length not enough can control to tie by the connection of upper end
Structure stretch telescopic section, after air bag is inflated by inflatable structure, after air bag be full of whole bone grafting position after, pass through upside
Inflatable structure understands aeration quantity, and further bone grafting amount needed for rough estimate；Deflated afterwards；Then by pushing or selecting
Push rod will be implanted into material and be pushed to and need to fill position, and the required bone amount measured by scale and before understands filling situation, waits to reach
It is finely adjusted during to required bone amount.Device is removed out after the completion of bone grafting.
Compared with prior art, the utility model novel bone grafting apparatus can carry out implantation material to set balloon structure
Rough estimate, prevent be implanted into bone amount it is excessive or very few；The setting of telescopic section can be effectively to different depth bone grafting part
Carry out material implantation.
