Abstract
The utility model discloses a bone knife is cut to ultrasonic wave with adjustable, which comprises a housin, one end in the casing is provided with piezo -actuator and the ultrasonic vibrator continuous with piezo -actuator, the last sleeve of installing of ultrasonic vibrator, this sleeve stretches out from the other end of casing. The utility model discloses an upward, lower scissor head installs through upper and lower cutter arbor to can adjust the position of cutter arbor through fastening bolt, on using the zigzag in the tool bit, can release and will descend the cutter arbor to push to the sleeve in going up the cutter arbor, it is regional that lower scissor head also shifts out the operation thereupon, and so only the surplus tool bit of going up just so prevents can hurt near the soft tissue in the regional work of operation when lower scissor head is idle, increases the factor of safety who performs the operation, reduction patient's misery.
Description
Technical field
This utility model relates to medical orthopaedics cutter, specifically a kind of adjustable 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.
First traditional cutter are that function ratio is more single, and a knife bar can only be equipped with a kind of blade, need to change when use; The length being exactly knife bar in addition can not regulate, or some scalpel regulates knife bar length by fastening bolt, regulates cumbersome.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, provides following technical scheme:
A kind of adjustable 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 vibrator is provided with a sleeve, this sleeve stretches out from the other end of housing 1.
As preferably, be provided with a knife bar that can move forward and backward in described sleeve, the cutter head end of described knife bar is provided with top cutter and bottom knife; Described sleeve is provided with a long groove, the side of described knife bar is also installed with a joint pin, this joint pin stretches out from long groove, and the end of joint pin is also provided with slide block.
As preferably, described long groove is also provided with the stopper slot protruded to both sides; The diameter of described joint pin and the diameter of stopper slot suitable.
As preferably, described sleeve is also provided with the fastening bolt for fixing knife bar; In order to further fix knife bar, sleeve is provided with fastening bolt.
As preferably, the stopper slot on described long groove is provided with five altogether, and adjacent stopper slot spacing is equal, and point both sides are crisscross arranged.
As preferably, described top cutter is serrated blade; Bottom knife is blade-like blade; A knife bar arranges two kinds of different blades, when use, need not scalpel be changed.
As preferably, in described housing, be also provided with fluidic device.
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) sleeve of the present utility model arranges long groove, the joint pin that knife bar is installed stretches out from long groove, therefore knife bar can be driven to move in sleeve by moving slider, the length of knife bar can either be regulated like this, and when slide block is moved near some stopper slots, by swivel knife carrier, joint pin is screwed in in stopper slot, so just can regulate the length of knife bar, after but knife bar regulates length, when using, under the effect of ultrasonic vibrator, knife bar may produce swing by a small margin in front and back in stopper slot, at this moment by lock bolt, knife bar is locked, regulative mode very simple and practical,
(3) stopper slot on long groove of the present utility model is provided with multiple, and therefore the length adjustment of knife bar is provided with multiple gear, and practicality is got up also very convenient.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Fig. 2 is the A direction view in Fig. 1.
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 depicted in figs. 1 and 2, a kind of adjustable 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 vibrator 3 is provided with a sleeve 4, this sleeve 4 stretches out from the other end of housing 1.
Be provided with a knife bar that can move forward and backward 5 in sleeve 4, the cutter head end of described knife bar 5 is provided with top cutter 51 and bottom knife 52; Described sleeve 4 is provided with a long groove 41, the side of described knife bar 5 is also installed with a joint pin 53, this joint pin 53 stretches out from long groove 41, and the end of joint pin 53 is also provided with slide block 54.
Long groove 41 is also provided with the stopper slot 42 protruded to both sides; The diameter of described joint pin 53 and the diameter of stopper slot 42 suitable.
Stopper slot 42 on long groove 41 is provided with five altogether, and adjacent stopper slot 42 spacing is equal, and point both sides are crisscross arranged.
Top cutter 51 is serrated blade; Bottom knife 52 is blade-like blade; A knife bar 5 arranges two kinds of different blades, when use, need not scalpel be changed.
Sleeve 4 is also provided with the fastening bolt 6 for fixing knife bar 5; In order to further fix knife bar 5, sleeve 4 is provided with fastening bolt 6.
Fluidic device 7 is also provided with in housing 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.
Sleeve of the present utility model arranges long groove, the joint pin that knife bar is installed stretches out from long groove, therefore knife bar can be driven to move in sleeve by moving slider, the length of knife bar can either be regulated like this, and when slide block is moved near some stopper slots, by swivel knife carrier, joint pin is screwed in in stopper slot, so just can regulate the length of knife bar, after but knife bar regulates length, when using, under the effect of ultrasonic vibrator, knife bar may produce swing by a small margin in front and back in stopper slot, at this moment by lock bolt, knife bar is locked, regulative mode very simple and practical.
