Abstract
This utility model relates to the technical field of medical apparatus and instruments, especially a kind of orthopaedics dynamic growth rod, comprise pitman one, block, resilient sleeve and pitman two, resilient sleeve is that monolateral tapering is the taper resilient sleeve of 2 °-10 °, resilient sleeve is in axial direction provided with a groove and is provided with at least one groove, the notch of groove is arranged on the osculum of taper resilient sleeve, resilient sleeve is set on pitman one, the endoporus of pitman two is taper hole, in the taper hole that is arranged on pitman two of pitman one by resilient sleeve interference fit, block a shot through pitman one and push down resilient sleeve and be threaded with pitman two.This utility model provides a kind of dynamic growth supplemental support rod of the child's for the treatment of orthopaedic disease, by simple tapered configuration, dynamic growth rod can be increased along with patient's growth, continue performance interconnect function, until skeleton growth is sound, avoid patient due to second operation and Repeated Operation that growth causes, reduced patient's misery.
Description
technical field
This utility model relates to the technical field of medical apparatus and instruments, especially a kind of orthopaedics dynamic growth rod.
Background technology
In modern medicine, be used for the treatment of in the operation of child's scoliosis, be placed on the supplemental support rod in patient body, can not extend along with child's growth, must again perform the operation and again place again suitable supplemental support rod using certain degree, in the process of growing up, needs of patients carries out Repeated Operation, has brought very large misery to patient.
Utility model content
In order to overcome the deficiency of existing technology, this utility model provides a kind of orthopaedics dynamic growth rod.
This utility model solves the technical scheme that its technical problem adopts: a kind of orthopaedics dynamic growth rod, comprise pitman one, block, resilient sleeve and pitman two, described resilient sleeve is shaped as taper, the monolateral tapering of described resilient sleeve is 2 °-10 °, described resilient sleeve is in axial direction provided with a groove, described resilient sleeve is in axial direction also provided with at least one groove, the notch of described groove is arranged on the osculum of taper resilient sleeve, described resilient sleeve be set on pitman one and large mouthful upper, osculum under, the endoporus of described pitman two is taper hole, in the taper hole that is arranged on pitman two of described pitman one by resilient sleeve interference fit, described block is through pitman one and push down resilient sleeve and be threaded with pitman two.
The beneficial effects of the utility model are, a kind of dynamic growth supplemental support rod of the child's for the treatment of orthopaedic disease is provided, by simple tapered configuration, dynamic growth rod can be increased along with patient's growth, continue performance interconnect function, until skeleton growth is sound, avoid patient due to second operation and Repeated Operation that growth causes, reduce patient's misery.

Fig. 2 is the top view of this utility model resilient sleeve;
Fig. 3 is the front view of this utility model resilient sleeve.
1. pitmans one in figure, 2. block, 3. resilient sleeve, 4. pitman two, 5. groove, 6. groove, 7. taper hole.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of orthopaedics dynamic growth rod, comprise pitman 1, block 2, resilient sleeve 3 and pitman 24, resilient sleeve 3 is shaped as taper, the monolateral tapering of resilient sleeve 3 is 2 °-10 °, resilient sleeve 3 is in axial direction provided with a groove 5, resilient sleeve 3 is in axial direction also provided with at least one groove 6, the notch of groove 6 is arranged on the osculum of taper resilient sleeve 3, resilient sleeve 3 be set on pitman 1 and large mouthful upper, osculum under, the endoporus of pitman 24 is taper hole 7, in the taper hole that is arranged on pitman 247 of pitman 1 by resilient sleeve 3 interference fit, block 2 passes pitman 1 and pushes down resilient sleeve 3 and is threaded with pitman 24.
This utility model is used for the treatment of the dynamic growth supplemental support rod of child's orthopaedic disease, in the taper hole that is arranged on pitman 247 of pitman 1 by resilient sleeve 3 interference fit, by simple tapered configuration, dynamic growth rod can be increased along with patient's growth, continue performance interconnect function, until skeleton growth is sound, avoid patient due to second operation and Repeated Operation that growth causes, reduce patient's misery.
