Abstract
The utility model discloses a bone knife is cut to double-purpose formula ultrasonic wave, which comprises a housin, one end in the casing is provided with piezoelectric driver and the ultrasonic vibrator who links to each other with piezoelectric driver, install a sleeve on the ultrasonic driver, this sleeve stretches out from the other end of casing. The utility model has the advantages that the cutter head is arranged into a sawtooth-shaped upper cutter head and a blade-shaped lower cutter head, and the sawtooth-shaped upper cutter head can be used for cutting hard bone tissues by matching with the vibration of the ultrasonic vibrator; and the lower blade of blade form can cut cartilage tissue, perhaps can cooperate ultrasonic vibrator's vibration to some neutral bone tissue cutting, can cut different bone tissue, and the function is various, convenient operation.
Description
Technical field
This utility model relates to medical orthopaedics cutter, specifically a kind of double-purpose type ultrasound wave bone cutter.
Background technology
Electric energy conversion mainly becomes ultrasound wave to vibrate by piezo technology by ultrasound wave bone cutter, ultrasonic mechanical effect is utilized to make cutter head produce the telescopic vibration of fore-and-aft direction, coordinate cutter head to carry out deep, time deep, Oscillation Amplitude should not be excessive, therefore adopts ultrasound wave vibration the most suitable.
When carrying out deep, cartilaginous tissue is needed to cut with the sharp blade with certain degree of hardness, and os osseum is needed to use jagged sharp cutter coordinate hyperacoustic vibration to complete deep by osseous tissue impact grinding, therefore different operations is needed to prepare different bone cutters, trouble very; Existing bone cutter knife bar length is fixed in addition, can not regulate, and uses very inconvenient.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, provides following technical scheme:
A kind of double-purpose type ultrasound wave bone cutter, comprise housing, the ultrasonic vibrator that the one end in described housing is provided with piezoelectric actuator and is connected with piezoelectric actuator, described ultrasonic drive is provided with a sleeve, this sleeve stretches out from the other end of housing.
As preferably, be also provided with a knife bar in described sleeve, the other end of described knife bar is provided with cutter head, and described cutter head is divided into shape to be the upper cutter head of arc and lower cutter head; Described upper cutter head is zigzag cutter head, and described lower cutter head is lamellar cutter head.
As preferably, described knife bar is arranged in sleeve, and can move forward and backward in sleeve, described sleeve is also provided with the fastening bolt for fixing knife bar.
As preferably, in described housing, be also provided with fluidic device; Fluidic device is used for carrying out rinsing the blood oozed out when carrying out osseous tissue excision, ensures the carrying out of operation.
As preferably, described knife bar is long is 10cm.The length of knife bar should be moderate, is beneficial to adjustment.
Beneficial effect: compared with prior art, this utility model has the following advantages:
(1) cutter head of the present utility model is arranged to zigzag upper cutter head and cultrate lower cutter head, and zigzag upper cutter head coordinates the vibration of ultrasonic vibrator to may be used for the cutting of hard bone tissue; And cultrate lower cutter head can cut cartilaginous tissue, or the vibration of ultrasonic vibrator can be coordinated to cut some neutral osseous tissues, different osseous tissues can be cut, diverse in function, easy to operate;
(2) knife bar of the present utility model designs different from traditional knife bar, but be provided with a sleeve set knife bar, not that knife bar is directly installed on ultrasonic vibrator, knife bar can move in sleeve, and be fixed by fastening bolt, therefore the adjustable in length of knife bar, uses very convenient.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate this utility model further, the present embodiment is implemented under premised on technical solutions of the utility model, should understand these embodiments and only be not used in restriction scope of the present utility model for illustration of this utility model.
As shown in Figure 1, a kind of double-purpose type ultrasound wave bone cutter, comprises housing 1, the ultrasonic vibrator 3 that the one end in described housing 1 is provided with piezoelectric actuator 2 and is connected with piezoelectric actuator 2, described ultrasonic drive 3 is provided with a sleeve 4, this sleeve 4 stretches out from the other end of housing 1.
Also be provided with a knife bar 5 in described sleeve 4, the other end of described knife bar 5 is provided with cutter head 6, and described cutter head 6 is divided into shape to be the upper cutter head 61 of arc and lower cutter head 62; Described upper cutter head 61 is zigzag cutter head, and described lower cutter head 62 is lamellar cutter head.
The shape of upper and lower cutter head can freely design, and also can be arranged to semicircle cutter head or arc cutter head, and the shape of upper and lower cutter head answers size identical, convenient operation.
Described knife bar 5 is arranged in sleeve 4, and can move forward and backward in sleeve 4, described sleeve 4 is also provided with the fastening bolt 7 for fixing knife bar 5; The length of knife bar 5 can arrange 5-15cm, and containing more operation as much as possible may.
Fluidic device 8 is also provided with in described housing 1; Fluidic device 8, for carrying out rinsing the blood oozed out when carrying out osseous tissue excision, ensures the carrying out of operation.
Fluidic device 7 is mainly arranged on the port of enclosure interior, and while carrying out surgical cut, fluidic device 7 pairs of wounds rinse, and ensure that operation is carried out normally, this device has setting in a lot of scalpels.
Cutter head of the present utility model is arranged to zigzag upper cutter head and cultrate lower cutter head, according to the cooperation of upper and lower cutter head and ultrasonic vibrator, can be divided into multiple situation:
(1) zigzag upper cutter head can coordinate the vibration of ultrasonic vibrator to may be used for the cutting of hard bone tissue;
(2) cultrate lower cutter head can cut cartilaginous tissue by its sharp blade;
(3) under, cutter head also can coordinate the vibration of ultrasonic vibrator to cut some neutral osseous tissues, can cut different osseous tissues, diverse in function, easy to operate;
Knife bar of the present utility model designs different from traditional knife bar, but be provided with a sleeve set knife bar, not that knife bar is directly installed on ultrasonic vibrator, knife bar can move in sleeve, and be fixed by fastening bolt, therefore the adjustable in length of knife bar, uses very convenient.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
