Description
Technical field
This utility model is related to a kind of spinal column two-way adjustable type growth valve, belongs to the technical field of medical apparatus and instruments.
Background technology
Initially the theory of proposition growing rod technology is:Design a kind of support system, insert spinal column side, both can correct ridge
Post side is convex, keeps orthopedic effect, can constantly strut prolongation according to the needs of infant growth promoter again.Adjustable system on market
Device is all growth regulation valve to change the Orthopedic rod of one side so that operating time is long, upper and lower Orthopedic rod discontinuity so that
Orthopedic rod bends, and causes this thrashing, and adjusting means is larger, have higher incisura, have cavity to be formed, and increases latent infection
Risk.The complex structure of adjusting means, the strength and stability of device is not high, there is certain risk with postoperative in art.
Utility model content
The purpose of this utility model is to provide a kind of spinal column two-way adjustable type growth valve, and this growth valve regulation operation technique can
Under local anaesthesia, little otch is carried out, and extend that adjustability is good, extend during safety is good, stress uniformly, fast, the transmission that extends efficiency
Stable.
For reaching above-mentioned purpose, the technical scheme that this utility model is adopted is:
A kind of two-way adjustable type of spinal column grows valve, including drive socket, locking nail and two Orthopedic rods;Drive socket
It is provided with female thread on two inner wall of ends;Two Orthopedic rods are all joined respectively by the external screw thread in setting at one end outer wall
Close the two ends being arranged on drive socket(That is, two Orthopedic rods are threaded connection respectively and coordinate and be arranged on the two of drive socket
On individual end), wherein, the external screw thread on an Orthopedic rod outer wall is left hand thread, the external screw thread on another Orthopedic rod outer wall
For right-handed thread;The tapped through hole running through female thread is offered on one end wall body of drive socket, locking nail cooperation is arranged on this
In tapped through hole, and summit is convexly equipped with the medial surface of locking nail, the lateral surface of locking nail is concavely provided with non-circular counterbore, top
Point, non-circular counterbore, the concentric setting of locking nail three, simultaneously summit hold out against the externally threaded thread groove in respective end Orthopedic rod
Interior.
As the setting further of such scheme, one end outer wall of described drive socket is provided with spanner interface, and pulls
Handss interface is located at same one end of drive socket with tapped through hole.Spanner interface is used for the rotation coordinating spanner to realize to drive socket
Turn.In this utility model, spanner interface is preferably die nut interface, Octagonal wrench interface.
External screw thread on described Orthopedic rod is double thread, correspondingly, interior on two inner wall of ends of drive socket
Screw thread is also double thread.The setting of double thread, can effectively shorten operating time.
Two end wall bodies of described drive socket thicken setting.In being provided with two inner wall of ends of drive socket
Screw thread, is used for the Orthopedic rod that is connected, and the thickening setting of this two end wall bodies to drive socket, transmission can be effectively improved
The structural strength of sleeve.
External screw thread on described Orthopedic rod adopts minus thread structure design.
The two-way adjustable type of this utility model spinal column grows valve, using double stick Bidirectional extension mode, upper and lower two Orthopedic rod bands
Negative angle is had to be threaded through the threaded of intermediate transmission sleeve, rotary drive sleeve makes two Orthopedic rods extend simultaneously or contract
Short, control the development length of growth valve by the anglec of rotation of drive socket.
The two-way adjustable type of this utility model spinal column grows valve, by unclamping locking nail, rotary drive sleeve, is passed by screw thread
Dynamic two Orthopedic rods move up and down, and after reaching required development length, lock locking nail.Locking nail is threadedly attached in
On drive socket, because locking nail bottom is to carry top design, by screwing sinking, hold out against the thread groove of Orthopedic rod, thus
Reach locking purpose.
Main innovation point of the present utility model:
One. safe
1. Orthopedic rod adopts bi-directional synchronization to extend it is ensured that good transmission speed and stable transmission reliability;
2. adopt screw-like to design in Orthopedic rod extendable portion, minus thread structure design, plays anti-down effect, double end spiral shell
The design of stricture of vagina fine pitch so that during extending stress uniformly and conduction velocity is fast.
Growth valve regulation operative process is little otch carries out operation and can complete under local anesthesia, with routine
Surgery of scoliosis is compared, and wound is little, and operating time is short, recovers fast, few intercurrent disease, and amount of bleeding is also little.Due to child
Growth promoter is very fast, therefore after skoliosis orthomorphia, need to strut orthopedic again every 6~10 months, to keep solid in spinal column
That determines system persistently struts effect.And this utility model, operation process can shorten extension time interval, be truly realized few
Amount repeatedly, reduces the risk in whole operation process.Be easier to strut than external " rod-pulling type " growth valve, stability strong, operation
Later stage is difficult to loosen.
Two. adjustability is good
The two-way adjustable type of this utility model spinal column grows the kind of drive of valve using the structure being screwed, and is adjusted by spanner
Section drive socket, is threaded connection between drive socket and Orthopedic rod, so that two Orthopedic rods is extended under the conduction of screw thread, due to
Helicitic texture, so that two Orthopedic rods move axially along the two-way even of predetermined direction, reaches the support of needs
After opening effect, locked by locking nail.
Three. operating time is short
The two-way adjustable type of this utility model spinal column grows the kind of drive of valve using the structure being screwed, due to drive sleeve
It is that two ends respectively have female thread in cylinder, and helicitic texture adopts double thread to design, that is, by rotating a drive socket, prolong
Stretch distance for 4 times of routine growth valve development length, by the shorter time, reach surgical effect.
Four. less invasive techniques
Conventional skoliosis straightening technique needs to put into implant system so that creating in the very big situation of otch
Wound is big, can extend operating time, postoperative patient is long for recovery time, complication easily.
And after applying this utility model, operation process can carry out under local anesthesia it is only necessary to length 1cm little otch
Under can complete operate, so even for young infant cooperation basal anesthesia also very convenient.
In a word, this utility model spinal column two-way adjustable type growth valve regulation operation technique little otch can be carried out under local anaesthesia,
Operating time is short and extend that adjustability is good, extend during stress uniformly, stable transmission, conduction velocity fast.
The high-end product of this utility model energy import substitutes, and price is only import 1/2-1/3, benefits vast trouble
Person.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
