Description
Technical field
The present invention relates to a kind of medical apparatus, be specifically related to a kind of bone-cutting device for dissecting.
Background technology
At present, wanting to open thoracic cavity during pathological anatomy, cutting off rib is a thing the most troublesome, generally uses and stings bone
Pincers, metal shears etc., these instruments are not only wasted time and energy when using, or a kind of heavy muscular labor；Now can be with electricity consumption
Dynamic cutting machine cuts, but owing to rotating speed of flail is the highest, causes organic organization to fly upward, and brings a lot of tired to user
Angry.
Disclosed a kind of bone cutting machine in Chinese patent literature, notification number is CN202958624U, including base, on base
Being provided with two leads, each lead is provided with guide pad, is provided with blade between guide pad, and lead upper end is fixedly connected with horizontal stroke
Bar, cross bar is hinged with depression bar, and guide pad is hinged with a connecting rod, and the free end of connecting rod is hinged with depression bar, by by cutter
Sheet is arranged on guide pad, drives depression bar to will pass through connecting rod and makes guide pad move downward, thus band cutting blade moves downward, and cuts
The bone of disconnected Os Sus domestica etc.First this machinery is mainly used in food aspect, and pathological anatomy must be cutting of one side opening
Cutter, such linkage rod slide block mechanism, owing between slide block with base, the shearing force of blade and the direction of motion of connecting rod are consistent
, approximate with shears, be not easy to the shearing of this rib.
Summary of the invention
The invention aims to solve existing bone cutting machine and be not used to the operational issue of pathological anatomy cut-out skeleton,
There is provided a kind of can be with the pathological anatomy bone-cutting device of one-handed performance.
To achieve these goals, the present invention is by the following technical solutions:
A kind of dissection bone-cutting device, including a body, the middle part of body is provided with horizontal concrete chute, and the lower section of horizontal concrete chute is provided with
Vertical chute, the hinged swing arm of body one side-lower, the paraxial place in the middle part of swing arm directly contacts with the cross sliding clock on body
Or hinged with the cross sliding clock on horizontal concrete chute by a hinged connecting rod, vertical chute is provided with vertical slipper, two
Using push rod hinged between slide block respectively, the bottom of vertical slipper is provided with cutting knife, and the lower section of cutting knife is the base plate being connected with body, water
One end of smooth block is provided with back-moving spring.
During work, the opening between cutting knife and base plate being put at skeleton to be cut off, swing arm inwardly swings, push directly on or
Person promotes cross sliding clock compression reseting spring to move by connecting rod, and cross sliding clock drives hinged pushrod movement, and push rod drives and hangs down
Straight slide block moves downward, and the cutting knife of vertical slipper bottom is reducing with the spacing of base plate, until spacing is zero；So skeleton just by
Cutting knife cuts off.Generally, connecting rod in swing arm or the contact point of cross sliding clock at 1st/to four/3rds of swing arm,
The locomotivity assuming at this point that swing arm end is 2 kilograms, and cross sliding clock just has a locomotivity zooming into 3-4 times, cross sliding clock and
The angle of push rod, usually between 60-90 degree, angle is the biggest, and the compression stress suffered by push rod is the biggest, then pass through push rod
It is delivered to the shearing force on vertical slipper blade and will reach ten a few to tens of kilograms, enough cut off general skeleton.By this
Individual push rod and the combination of slide block, it is also possible to the locomotivity of horizontal direction, change into the downward shearing force of several times, facilitate disease
Understand the shearing manipulation cuing open skeleton.
As preferably, described body is at conplane wedge shape thin-wall construction with cutting knife cutting edge with the connecting place of base plate.
This wedge shape thin-wall construction is like blade, it is simple to the otch along knochenbruch moves inwards, proceeds deep operation.
As preferably, described body nearly swing arm side is provided with elongated hole or the groove that can stretch into palm.This on body
Hole or groove, can stretch into the palm in addition to thumb, hold up equipment, and make the opening part below cutting knife cutting edge to contain to want
The skeleton cut off, with finger tip catch on swing arm inwardly swing just can the deep operation of singlehanded enforcement, along with opening part moves forward, can
To be repeatedly carried out continuously deep operation.
As preferably, described cross sliding clock and the angle of push rod, 45 degree will be consistently greater than.According to Mechanics Calculation, if not
The mobile frictional force of meter slide block, cross sliding clock and the angle of push rod, during equal to 45 degree, cross sliding clock and the locomotivity of vertical slipper
Time the same, but when cross sliding clock and the angle of push rod, during more than 45 degree, the shearing force level to be far longer than of vertical slipper
The locomotivity of slide block, angle is the biggest, and shearing force is the biggest, optimum data be angle between 60-90 degree (without 90 degree), cutting knife
Shearing force reaches to maximize.
As preferably, described cross sliding clock is cambered surface or rolling structure with the contact position of swing arm.So can alleviate
Frictional force between swing arm and cross sliding clock.
As preferably, the section of described cross sliding clock is rectangle, the cross sliding clock upper contact surface in body for slide or
Person's rolling structure.Pressure ratio suffered by the upper contact surface of cross sliding clock is relatively big, and such rolling friction can be dropped effectively
Frictional force between low body and cross sliding clock, the service life of extension fixture.
As preferably, described cutting knife cutting edge and cross sliding clock move in a parallel plane.So, cutting knife opening part with
The swaying direction of swing arm is identical, it is simple to deep operation.
As preferably, described cutting knife cutting edge and cross sliding clock move in a vertical plane.So, cutting knife opening part with
The swaying direction of swing arm is vertical, it is simple to the operation of some occasion.
As preferably, the length of described push rod can regulate.Change the length of push rod, just change push rod and cross sliding clock
Angle, the most just change.
As preferably, the bottom of described vertical slipper connects vibrator, and vibrator connects cutting knife, and described vibrator connects to be had
Power supply.This structure be and to top vibrator is installed, vibrator is powered by power supply, generally uses DC source, this
The purpose of sample is, greatly reduces cut-out power.
There is advantages that can be with one-handed performance, and the less active force of finger tension swing arm amplifies
Several times and change over downward cut-out power, easily cut off the required skeleton sheared, and convenient repeatedly shear.
