Abstract
The utility model provides a sleeve pjncture needle for computer navigation operation, by the sleeve, pjncture needle and fixed fixture are formed, the sleeve is hollow cylinder, the hollow female cylinder hand wheel A of circumference is fixed to one end, hollow cylinder's the fixed circumference hollow cylinder hand wheel B of pjncture needle one end, the cylinder of hand wheel end has the external screw thread, the other end is the hollow needle point of toper, the pjncture needle external diameter is less than sleeve diameter, insert pjncture needle needle point end from sleeve cylinder hand wheel B end and wear out the sleeve other end, external screw thread and sleeve centre bore internal thread thread tightening, form double casing pipe, the fixed fixture of drum are emboliaed to the tight fit on the sleeve external diameter, go -between on the fixed fixture passes through the jackscrew to be fixed on the navigation tracer. The utility model discloses a compound double casing pipe structure, completion puncture or osteoma radio frequency melt the operation under the computer navigation, can reduce the operation error, simple structure, convenient operation improves the accuracy of operation.
Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of sleeve puncture needle for computer navigation operation.
Background technology
Along with Computer navigation surgery is in the extensive application of orthopaedics, bone tumor section has the most successfully carried out computer navigation menisectomy, including osteoid osteoma radio-frequency ablation procedure etc. under percutaneous biopsy under computer navigation and computer navigation.But existing puncture biopsy needle cannot be fixed with navigator tracer, present way is first to position under navigation, then punches with electric drill, after arriving tumor, takes tumor tissues with puncture biopsy needle.Due to punching and puncture cannot real-time navigation, cause in operating process produce error.Same radio-frequency (RF) ablation tumor needs sleeve as service aisle, and existing sleeve also cannot be fixed with navigator tracer, error easily occurs, affect surgical effect in art.Research and develop and a kind of directly can fix with the tracer of computer navigation, both the Needle Biopsy of Bone under computer navigation can be carried out, it is also possible to as sleeve as puncture biopsy needle, for the canula puncture needle of the active channel of radio-frequency (RF) ablation, it it is the vital task that currently faces of this area.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in construction, convenient and practical, directly can fix with the tracer of computer navigation, for the active channel of radio-frequency (RF) ablation and carry out the sleeve puncture needle of aspiration biopsy.
For above-mentioned purpose, the technical scheme of this utility model following structure of employing: a kind of sleeve puncture needle for computer navigation operation, it is made up of sleeve, puncture needle and holding clamp, it is characterized in: sleeve is hollow cylinder, one end fixing circumference hollow cylinder handwheel A, handwheel A centre bore is female thread structure, and the other end is cantilever end；Puncture needle one end of hollow cylinder fixing circumference hollow cylinder handwheel B, the cylinder of handwheel B pressed close to by puncture needle external screw thread, the other end is conical hollow needle point, puncture needle external diameter is less than sleeve diameter, puncture needle needle tip is inserted from sleeve cylinder handwheel A end, pass sleeve cantilever end, the female thread threaded engagement of the external screw thread on puncture needle and sleeve handwheel centre bore is fixed, form bilayer sleeve, holding clamp top is hollow cylinder, barrel bore is corresponding with sleeve outer diameter, tight fit is inserted on sleeve cylinder, the hollow cylinder external diameter of holding clamp is provided with fixing square connection ring, fixing square connection ring bottom upwards longitudinal matching thread jackscrew, thus constitute a kind of sleeve puncture needle for computer navigation operation.
When this utility model uses, by holding clamp, sleeve puncture needle is fixed on the tracer of navigator, when carrying out percutaneous biopsy, fix in puncture needle is screwed in sleeve, percutaneous biopsy, accurate positioning can be completed, it is to avoid the error produced during puncture procedure under computer navigation.When carrying out osteoma radio-frequency ablation procedure, puncture needle screwing out sleeve, cannulated sleeve just becomes the service aisle of radio-frequency ablation procedure, completes osteoma radio-frequency ablation procedure under computer navigation.
This utility model uses composite double layer sleeve structure, completes different types of operation under computer navigation, it is possible to minimizing surgical errors, and simple in construction is easy to operate, improves accuracy and the convenience of operation, has reached goal of the invention.
