Description

A kind of high frequency electric knife experimental provision
Technical field
The present invention relates to the experimental provision of a kind of high frequency medical treatment electric knife.
Background technology
Flourish along with medical apparatus and instruments, high frequency electric knife (high frequency electro surgical unit) has replaced mechanical operation cutter as the electrosurgical unit of tissue cutting and has been applied in many surgical operations in many surgical operations.It is made up of the high frequency generator in high frequency electric knife, patient's pole plate, wire and electrode; Electric current through patient, then is returned the generator of high frequency electric knife by wire and cutter head (electrode) by patient's pole plate and wire thereof; Produce high-frequency high-voltage current when electric current flows through eletrode tip contact with human body and heat tissue, realize the separation of when injected organism tissue and solidify, playing the object of cutting and stopping blooding simultaneously.
High frequency electric knife is used widely because having the advantages such as cutting speed is fast, haemostatic effect good, blood loss is few, range of operation is wide, and current domestic big-and-middle-sized hospital is all equipped with high frequency electric knife.The outstanding problem existed in the use of reality is: electrotome head (electrode) and when injected organism tissue make electric knife local temperature too high because discharging in cutting process, tissue adherence forms the eschar being difficult to remove on bit interface, increase Cutting Drag, reduce cutting efficiency, increase clipping time, thus increase the injury to tissue; Meanwhile, need frequently to change cutter head in operation, add operation easier and the cost of major operation.Therefore, need the test by special purpose test equipment badly, find the relation that the parameter such as shape, material of movement velocity, depth of cut, cutter head in electric knife motor process and eschar are formed; So that when performing the operation, reduce on electrotome head and form eschar, improve procedure efficiency, reduce the injury to tissue, reduce operation easier and the cost of operation.
Summary of the invention
The object of this invention is to provide a kind of high frequency electric knife experimental provision, when this experimental provision can simulate electrotomy, the cutter head of difformity and material cuts and organizes process; And cutting speed and depth of cut can be controlled in the process cut and organized.Thus find out the relation that the parameter such as shape, material of movement velocity, depth of cut, cutter head in electric knife motor process and eschar formed, thus provide the experimental basis of science for the design of high frequency electric knife, making and use; During to reduce operation, the formation of eschar on electrotome head, improves procedure efficiency, reduces the injury to tissue, reduces operation easier and the cost of operation.
The present invention realizes its goal of the invention, and the technical scheme adopted is: a kind of high frequency electric knife experimental provision, is characterized in that: be made up of electric knife feeding part and force plate/platform part;
The formation of described electric knife feeding part is: the main shaft of the servomotor on base plate one is connected with gear key, and gear engages with the tooth bar below it, and tooth bar is fixed on slide block one, and slide block one coordinates with the guide rail one on base plate one; The lateral projections at slide block one two ends forms touching block, and the side at guide rail one two ends is provided with the travel switch relative with touching block end face; The end face of the touching block of guide rail one front end is provided with to be erect and L-type support forward; The front end of L-type support is provided with the clamper of clamping high frequency electric knife.
The formation of force plate/platform part is: liftable support is fixed on base plate two, and the gripper shoe above base plate two is fixed on the lifting arm of liftable support, the fixing guide rail two parallel with guide rail one in gripper shoe, and the slide block two bottom loading panel coordinates with guide rail two; Loading panel is provided with the screwed hole connecting high frequency electric knife negative plate, gripper shoe is fixed with cantilever-beam force meter, and cantilever-beam force meter is positioned at the dead ahead of slide block biend.
Using method of the present invention and principle are:
High frequency electric knife is clamped on clamper, connect electric knife power supply, mobile loading panel makes the front end of slide block two contact with cantilever-beam force meter, is fixed on loading panel by the negative plate screw thread of high frequency electric knife, and negative plate is placed laboratory sample (animal tissue).Regulate the height of the lifting arm of liftable support, make negative plate and laboratory sample thereof be elevated to the position of setting depth of cut.
Start servomotor, by gear, tooth bar, slide block one is travelled forward by setting speed along guide rail one, thus the L-type support on slide block one and high frequency electric knife thereof are travelled forward; High frequency electric knife contacts the laboratory sample on negative plate in forward movement, carries out to sample the cutting setting depth of cut; In cutting process, loading panel has along the proal trend of guide rail under the effect of the Cutting Drags such as frictional force, and the slide block two of loading lower panels contacts with cantilever-beam force meter, stop loading panel to move, thus measure by the distortion of cantilever beam the Cutting Drag that electric knife produces in cutting process.When slide block two moves forward to extreme position, touching block touching travel switch; Immediately, servomotor stops the rotation, and namely completes a cutting experiment.
Laboratory sample on negative plate is moved, converts cutting position, cutting experiment next time can be carried out.
Compared with prior art, beneficial effect of the present invention:
One, electric knife can cut tissue automatically by the speed of setting and depth of cut, and automatically measures Cutting Drag when cutting.Combined the observation and analysis that electric knife is adhered to by serial experiment, the relation that in electric knife motor process, movement velocity, depth of cut, Cutting Drag and eschar are formed can be found out.
Two, change difformity, the cutter head of material carries out serial experiment, the relation that difformity, the cutter head of material and eschar are formed can be found out.
In a word, when experimental provision of the present invention can simulate electrotomy, the cutter head of difformity and material cuts and organizes process, and can control cutting speed, depth of cut in the process cut and organized, and measures Cutting Drag.Thus find out the relation that the parameter such as shape, material of movement velocity, depth of cut, cutter head in electric knife motor process and eschar formed, thus provide the experimental basis of science for the design of high frequency electric knife, making and use; During to reduce operation, the formation of eschar on electrotome head, improves procedure efficiency, reduces the injury to tissue, reduces operation easier and the cost of operation.
