Embodiment
Below in conjunction with the accompanying drawings and embodiment is made furtherly to operation provided by the utility model of tissue gripping devices
It is bright.
Embodiment 1
As shown in Figure 1, a kind of operation tissue gripping devices, it includes sucker 1, and the opening diameter of sucker 1 is 2-
5cm, is made of hard or elastomeric material.
The evacuation pipeline 2 being connected with the insertion of sucker inner chamber, the bottom for evacuating pipeline is provided with end cap 3.
As shown in Figure 1, be fixedly installed feed screw nut 4 in the inner chamber for evacuating pipeline, feed screw nut 4 and end cap 3 it
Between be fixed with two closed slides 5, guide rail 5 is axially arranged along pipeline is evacuated.
As shown in Figure 1, in addition to the sliding block 6 evacuated in inner cavity of pipe is arranged on, two closed slides 5 pass through sliding block 6,
Sliding block 6 can slidably, on sliding block fix spindle motor 7 along guide rail 5.
As shown in Figure 1, in addition to the first piston 8 evacuated in inner cavity of pipe of the top of feed screw nut 4 is arranged on, the
The bottom surface of one piston is inlaid with bearing 9, the top of leading screw 10 with being connected by bearing 9 with first piston 8, leading screw bottom with
Spindle motor 7 is connected, and leading screw 10 is free to rotate, again first piston 8 can be driven to move up and down when leading screw moves up and down.
As shown in Figure 1, in addition in the air inlet pipe 11 evacuated on pipeline lateral wall, one end and sucker of air inlet pipe
Chamber insertion, air inlet pipe is provided with stop valve 12.
The power supply of the device can use and battery case or external power supply power interface are set on the outer wall for evacuating pipeline, by electricity
Pond or power interface are electrically connected with spindle motor is provided with spindle motor rotating control button on the outer wall for evacuating pipeline simultaneously.
（Not shown in battery case, power interface and button accompanying drawing）.
When using the device, first the stop valve 12 in air inlet pipe is closed, outside air is completely cut off with sucker 1, sucker 1
Opening at flicking in removed tissue, push button, start spindle motor 7 drive screw mandrel 10 rotate, make screw mandrel 10 relative
Feed screw nut 4 axially moves, and leading screw 10 pulls first piston 8 to be slid axially along pipeline is evacuated, to sucker and evacuation pipeline
Front end is depressured, and sucker suction is in removed tissue under atmospheric pressure, by control the slip of first piston 8 away from
From the absorption affinity between adjustment sucker 1 and removed tissue, it is ensured that be removed tissue by stable and firm crawl.
After the completion of operation, stop valve 12 is opened, sucker 1 is connect in very short time by air inlet pipe 11 and outside air
Logical, the air pressure in sucker 1 returns to atmospheric pressure, and sucker 1 can just be separated with removed tissue easily.
Embodiment 2
The operation that the present embodiment is provided is further improved with tissue gripping devices on the basis of embodiment 1.
The tissue gripping devices that embodiment 1 is provided, because the shape irregularity for being removed tissue can cause sucker to exist
When starting crawl, the edge of sucker is difficult to and is removed tissue encapsulation and coincide, and causes crawl to fail.In view of the above-mentioned problems, this reality
Example is applied to be further improved.
As shown in accompanying drawing 2 and accompanying drawing 3, the grabbing device that the present embodiment is provided increases guiding on the basis of embodiment 1 and grabbed
Device is taken, the guiding grabbing device, which includes being fixed in the support plate 13 evacuated in pipeline 2, support plate, is provided with air-vent 14, props up
Support plate 13 is located at the top of first piston 8, fixes guide wire 15 in support plate 13, the top end opening of guide wire 15 and stretching is taken out
Vacant duct top is located in sucker 1, the bottom end opening of guide wire 15 and the bottom surface for stretching out support plate 13, and second is provided with guide wire
Piston 16, the top of piston rod 17 is connected with second piston, and the bottom of piston rod and the upper surface of first piston are connected.
After above-mentioned corrective measure, when carrying out crawl work, sucker 1 is offseted with removed tissue, group is removed
The part surface knitted enter suction cup interior and with the tip contact of guide wire 15, the stop valve 12 in air inlet pipe is closed, made
Outside air completely cuts off with sucker 1, pushes button, and starts spindle motor 7 and drives screw mandrel 10 to rotate, and makes screw mandrel 10 with respect to feed screw nut
4 axially move, and leading screw 10 pulls first piston 8, piston rod 17 and second piston 16 to slide axially downwards, second piston 16
Pressure reduction in the guide wire 15 of front end, because the diameter of guide wire 15 is smaller, its contact area with removed tissue is small,
Removed tissue can be directed to the absorption crawl of the front end of pipe 15 easily, and removed tissue is directed to after pipe crawl drawing, guide wire week
The tissue surface enclosed becomes the smooth edge easily with sucker and completely attached to, and glides, is produced in sucker 1 with the continuation of first piston
Raw negative pressure, is removed tissue and captures fixation completely by sucker.
After the completion of operation, stop valve 12 is opened, while inverting spindle motor, makes sucker 1 in very short time by air inlet
Pipe 11 is connected with outside air, and the air pressure in sucker 1 returns to atmospheric pressure, while second piston is moved upwards, sucker 1 and guiding
Tube top end can just be separated with removed tissue easily.
Embodiment 3
The present embodiment is that guiding grabbing device is further improved on the basis of embodiment 2.
The guiding grabbing device that embodiment 2 is provided, while sucker carries out absorption crawl, with the downslide of first piston,
Second piston in guide wire also glides therewith, causes the negative pressure of guide wire front end constantly to increase, and thus can not only cause to be cut
Except the local damage of tissue, larger pain can be also brought to patient.
The guiding grabbing device that the present embodiment is provided embodiment 2 is further improved.
As shown in accompanying drawing 4 and accompanying drawing 5, sliding groove 18, second piston are being provided with the inside pipe wall on the top of guide wire 15
16 are located in sliding groove 18, are provided with second piston bottom surface in piston rod apical pore, piston rod apical pore and inlay magnet ring 19, piston rod
Top carry magnetic plug 20, when the groove top contact on second piston 16 and the top of sliding groove 18, first piston 8 and second is lived
Plug 16 is located at upper dead center position, and the magnetic plug 20 of piston rod is located inside magnet ring 19, and piston rod 20 passes through with second piston 16
Magnetic suck realizes connection.
During work, when second piston 16 is produced in sliding groove groove top slide downward formula, the guide wire of second piston front end
Negative pressure, removed tissue is directed to pipe absorption crawl, when the bottom land of second piston glide downwards to sliding groove 18, second piston
16 are limited by the bottom land of sliding groove 18 and can not continue to glide, and piston rod 20 can be continued traveling downwardly with first piston 8, now piston
Bar 20 is separated with second piston 16, and the negative pressure value in the inner chamber of guide wire 15 of second piston front end no longer changes, and with first
The continuation of piston 8 is glided, and the negative pressure in sucker can strengthen, and removed tissue can be adsorbed crawl securely by sucker.Thus solve
The technical problem that persistently increases with the enhancing guide wire front end negative pressure of negative pressure in sucker.
Described above is only the utility model better embodiment, thus it is all according to constructing described in the utility model scope, it is special
Levy and equivalent change or modification that principle is done, be included in the utility model patent claim, the protection model of the application
Enclose and be defined by claims.
