Detailed description of the invention
Seeing Fig. 1-3, the present embodiment includes reciprocator, drawhead fixing device, trocar sheath fixing device, pressure
It is solid that device and force measuring device, the trocar sheath of the claw beam of surgical forceps for abdominoscope and the drawhead of claw beam are respectively arranged at trocar sheath
Determining in device and drawhead fixing device, reciprocator cylinder lever connecting rod head fixing device also drives drawhead fixing device to make
Moving back and forth, so that claw beam head makees the relative motion stretching and shrinking relative to claw beam body, pressure apparatus includes spring, spring
It is arranged between trocar sheath fixing device and force measuring device and externally sleeve fixing device imposes and claw beam head draw direction phase
Anti-pressure, force measuring device detection spring is exerted pressure namely the trocar sheath fixing device testing fatigue to carrying added by trocar sheath
Power.
In order to realize fixing claw beam head and drive, drawhead fixing device includes guide pillar, the guide pillar of groove-like is fixed
Block and slide block, one end of guide pillar is fixed on guide pillar fixed block, slide block has the slider throughbores passed for guide pillar and by sliding
Block through hole hangs on guide pillar, and slide block is provided with for the drawhead groove of steady brace head and in being fixed on by drawhead, back and forth transports
Dynamic device connection sliding block also drives slide block to move along guide pillar.
For the fixation clamps body of rod, trocar sheath fixing device includes that card cell body, card cell body are provided with the overcoat of fixed jacket pipe
Trocar sheath is also fixed on interior by tube seat, card cell body has the card cell body through hole passed for guide pillar and is hung over by card cell body through hole
On guide pillar and a side contacts guide pillar fixed block, card cell body be respectively arranged on slide block in guide pillar fixed block relative to both sides.
In order to adjust accordingly pressure, pressure apparatus also includes spring constraint bolt and regulation bolt, spring constraint bolt
Including key and the bolt head being arranged at key one end, the diameter of key is less than the internal diameter of spring, and the diameter of bolt head is more than spring
Internal diameter, spring housing is contained on key and extend out to outside key is not provided with the first end of bolt and contact force measurement apparatus, regulates bolt
Screw in the screw arranged to trocar sheath fixing device contact bolt head to adjust the decrement of spring.In the present embodiment, lead
Post fixed block is U-shaped, and the side of card cell body is pressed close on the side inwall of guide pillar fixed block.The bottom of card cell body is provided with for holding
Receive the dead slot of spring constraint bolt and spring.The opening of dead slot is towards force measuring device, after spring is inserted in dead slot, directly contacts
Force measuring device.The other end of dead slot is i.e. provided with screw, and guide pillar fixed block is provided with the bolt hole corresponding with screwhole position, adjusts
Joint bolt is screwed in screw by bolt hole again, in order to regulate pressure at any time.According to different needs, it is also possible to do not set
Through hole, the most first adjusts regulation bolt and starts test again.Also can not set dead slot, make spring directly pass through pressure compaction at draw-in groove
On body and force measuring device.
The reciprocator of the present embodiment includes motor, motor supporting base, sheave and connecting rod, and motor is fixed on motor and props up
On support seat, sheave is installed in the drive shaft of motor and is driven rotation by motor, and one end of connecting rod is fixed in the groove of sheave,
The other end is fixed in drawhead fixing device.And according to the needs of practical situation, it would however also be possible to employ as motor-driven screw mandrel,
Cylinders etc. are as reciprocator.
For the ease of controlling in real time and observation test case, the present embodiment also includes controlling display unit, controls display single
Unit is communicatively connected to reciprocator and force measuring device respectively, and controls start and stop and the survey of display power of reciprocator
The measurement numerical value of amount device.
In order to unify fixing device, it is simple to mobile, the present embodiment also includes that base plate, reciprocator, drawhead are fixed
Device, trocar sheath fixing device, pressure apparatus, force measuring device and control display unit are both secured on base plate.
In order to make spring play due force effect, regulate the bolt maximum compression length to spring constraint bolt, be less than
Spring extend out to the greatest length outside key.Be so in order to avoid spring constraint bolt two ends respectively directly contact card cell body and
Trocar sheath fixing device, making spring lose should have effect.
The control display unit of the present embodiment is used for controlling reducing motor rotating speed and number of revolutions and pressure measxurement list
The display of unit's force feedback, motor is arranged on motor supporting base and is fixed on base plate.Symmetry all it is machined with in card cell body and slide block
Guide pillar hole, guide pillar through both corresponding guide pillar holes and is fixed on two on guide pillar fixed block, so that card cell body and slide block
Can slide laterally along guide rail.It is provided with fixing claw beam on card cell body and fixes the draw-in groove of seat, and card slot length and claw beam fix seat
Length is consistent, and is provided with the draw-in groove laying pull bar bulb on slide block, then passes through slide block movement and makes pull bar with outer
Sleeve pipe generation relative movement, thus control the opening and closing degree of binding clip.Sheave, connecting rod, guide pillar fixed block, guide pillar, slide block composition song
Handle slide block mechanism by driven by motor realize its motion, slide block stretch and regain two extreme positions when, driving link groove
The two positions that on wheel, crank is corresponding is on same straight line, so this mechanism is without the anxious characteristic returned, slide block is when stroke and return
Being all to move along a straight line slowly, then the opening and closing speed of binding clip is consistent, thus simulates operational circumstances actual in operation.Spring
Being inserted in from the head end of spring constraint bolt, be then charged on card cell body in the hole of correspondence, now the end of spring should be pressed when assembling
On the surface of pressure measuring module, but spring constraint bolt must not stretch out spring end and contact with pressure measuring module.Regulation bolt
By the screw that screws on card cell body thus withstand the end of spring constraint bolt, the pine that then spring contacts with pressure sensitive unit
Tight degree is adjusted by regulating bolt, and the counteracting force of spring makes card cell body can only carry out limited slip along guide rail,
When test, card cell body will not contact with pressure sensitive unit all the time.
When carrying out the fatigue property test of operating forceps, first the end of claw beam seat and pull bar is snapped on card cell body and slide block
In corresponding groove, the most manually rotate sheave and be parked at range, crank when i.e. binding clip opens maximum angle
Position, rotates regulation bolt and sets pulling force to be applied, and the numerical value of pulling force is controlling display on display unit, is controlling simultaneously
Arrange on display unit and need the number of times of circulation just the weaknesses such as operating forceps pull bar and binding clip linkage can be in circulation
Pulling force effect under intensity, the mechanical property such as rigidity measures and assesses.This device can effectively reduce testing cost and
Avoiding the impact that subjective factors brings, test speed is fast and result is accurate, it is ensured that the safety of product and effectiveness.
This utility model is not limited to above-mentioned embodiment, no matter making any change on its shape or material are constituted, all
It is to use structure provided by the utility model design, is all a kind of deformation of the present utility model, is all considered as in this practicality new
Within type protection domain.
