Abstract
The invention discloses a piezosurgery and a using method thereof, wherein the piezosurgery comprises an ultrasonic transducer, a cutter head and a protection casing; the cutter head is connected with the ultrasonic transducer; the protection casing is hollow and mounted on the periphery the cutter head; and the protection casing is used for controlling the activity scope of the cutter head. After using the technical scheme provided in the invention, the activity scope of the piezosurgery is controlled; and the precision and surgery safety of orthopaedic surgery are improved.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular to a kind of piezosurgery osteotomy and method for using thereof.
Background technology
In bone surgery, often use piezosurgery osteotomy to bone cut, grinding, planing, scraping or any reshaping.The doctor goes to control the range of activity of piezosurgery osteotomy often according to the ability of self when carrying out this operation, such as the degree of depth etc. of cutting; Has very strong subjectivity; Especially bone surgery needs certain dynamics, in case dynamics control is wrong, tends to cut to the tissue beyond the predetermined depth; Enlarge wound surface, be unfavorable for patient's treatment.
Summary of the invention
The objective of the invention is to propose a kind of piezosurgery osteotomy and method for using thereof, can control the range of activity of piezosurgery osteotomy, improve the degree of accuracy and the operation safety of bone surgery.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of piezosurgery osteotomy comprises ultrasonic transducer, cutter head and protective sleeve, and cutter head is connected with ultrasonic transducer, protective sleeve hollow, and protective sleeve is installed in the cutter head periphery, and protective sleeve is used to control the cutter head range of activity.
Protective sleeve is connected with ultrasonic transducer through helicitic texture.
Protective sleeve interior shape and cutter head external shape are coincide.
Ultrasonic transducer set inside pipeline; Cutter head is provided with pipeline near the middle part of ultrasonic transducer one end; Inside one end of cutter head pipeline is provided with side opening; Side opening leads to the space between cutter head and the protective sleeve, the pipeline intercommunication of the pipeline of ultrasonic transducer and cutter head, be used for infusion liquid from an end of ultrasonic transducer through the pipeline of ultrasonic transducer, pipeline, side opening and the cutter head of cutter head and the point of a knife that the space between the protective sleeve flows to cutter head.
A kind of method for using of piezosurgery osteotomy may further comprise the steps:
Cutter head is connected with ultrasonic transducer;
Protective sleeve is enclosed within on the cutter head, and protective sleeve is connected with ultrasonic transducer through screw thread;
When piezosurgery osteotomy used, the degree of depth of cutting arrived the degree of depth that needs cutting through rotary threaded with the length adjustment that cutter head stretches out protective sleeve as required.
After piezosurgery osteotomy is finished using, cutter head is regained in the protective sleeve through rotary threaded.
Infusion liquid from an end of ultrasonic transducer through the pipeline of ultrasonic transducer, pipeline, side opening and the cutter head of cutter head and the point of a knife that the space between the protective sleeve flows to cutter head.
Adopted technical scheme of the present invention; Not only can improve the degree of accuracy and the operation safety of bone surgery, and protective sleeve can support cutter head through the range of activity of protective sleeve control piezosurgery osteotomy; Improved the service life of cutter head; Protective sleeve can be taken in cutter head simultaneously, has protected cutter head, has guaranteed the cleaning of cutter head.Guarantee that in addition infusion liquid flow to the point of a knife part of cutter head, wound surface is cleaned that guarantee the wound surface cleaning, surgical field of view is clear, improves the operation quality, and infusion liquid is cooled off cutter head itself, guarantee that tool temperature can be not too high and scald tissue.
Description of drawings
Fig. 1 is the structural representation of piezosurgery osteotomy in the specific embodiment of the invention.
Fig. 2 is the cross-sectional view of piezosurgery osteotomy in the specific embodiment of the invention.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment.
Fig. 1 is the structural representation of piezosurgery osteotomy in the specific embodiment of the invention.As shown in Figure 1, this piezosurgery osteotomy comprises ultrasonic transducer 1, cutter head 3 and protective sleeve 2.
Cutter head is connected through screwed with ultrasonic transducer, protective sleeve hollow, and interior shape and cutter head external shape are coincide, and protective sleeve is installed in the cutter head periphery, and protective sleeve can be controlled the cutter head range of activity, and protective sleeve is connected with ultrasonic transducer through helicitic texture.
When using piezosurgery osteotomy; Cutter head tightened with ultrasonic transducer be connected, protective sleeve is enclosed within on the cutter head, and protective sleeve is connected with ultrasonic transducer through screw thread; The degree of depth of cutting arrives the degree of depth that needs cutting through rotary threaded with the length adjustment that cutter head stretches out protective sleeve as required.
Like this since the size of protective sleeve greater than the size of cutter head; No matter when the cutter head that uses Any shape cuts; The size of the groove that is cut out all can be littler than the size of protective sleeve, and when cutting to the degree of depth that sets in advance, protective sleeve will be withstood by the tissue around the grooving; The tissue that surpasses beyond the predetermined depth will can not be cut, thereby reach protective effect and clean cut effect.And because the support of protective sleeve, the service life of also having improved cutter head have been arranged.
After piezosurgery osteotomy is finished using, through rotary threaded cutter head is regained in the protective sleeve, then both can protect cutter head, also can guarantee the cutter head cleaning.
Fig. 2 is the cross-sectional view of piezosurgery osteotomy in the specific embodiment of the invention.As shown in Figure 2, ultrasonic transducer set inside pipeline 4, cutter head is provided with pipeline 5 near the middle part of ultrasonic transducer one end; Inside one end of cutter head pipeline is provided with side opening 6, and side opening leads to the space 7 between cutter head and the protective sleeve, the pipeline intercommunication of the pipeline of ultrasonic transducer and cutter head; Infusion liquid, is cleaned wound surface through the pipeline of ultrasonic transducer, pipeline, side opening and the cutter head of cutter head and the point of a knife that the space between the protective sleeve flows to cutter head from an end of ultrasonic transducer, guarantees the wound surface cleaning; Surgical field of view is clear; Improve the operation quality, simultaneously infusion liquid is cooled off to cutter head itself, guarantee that tool temperature can be not too high and scald tissue.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
