It such as Fig. 2, is specifically that one group long-armed 1 is tong arm, and one group of galianconism 2 is control arm, and one group of galianconism, 2 one end is living
Dynamic to be connected in clamp block, the other end is connected to long-armed 1 middle part, and one group long-armed 1 is movably connected in 5 one end of push-pull rod, the push-and-pull
5 other end of bar is connected to drag-line 8.
Galianconism 2 includes the first galianconism 2a and the second galianconism 2b, and the first galianconism 2a is equipped with one group of first through hole 11a, and second
Galianconism 2b is equipped with one group of second through-hole 11b, and 6 both ends of clamp block are respectively equipped with the first clamp block through-hole 6a and the second clamp block through-hole 6b,
Clamp block includes the first pin 3, and the first pin 3 passes through the first clamp block through-hole 6a, first through hole 11a, the second through-hole 11b and the second clamp block
First galianconism 2a and the second galianconism 2b are movably connected in clamp block 6 by through-hole 6b；
Long-armed 1 includes the first long-armed 1a and the second long-armed 1b, and the first long-armed 1a is equipped with one group of third through-hole 12a, and second
Long-armed 1b is equipped with one group of fourth hole 12b, and push-pull rod 5 is equipped with push-and-pull rod through-hole 5a, and push-pull rod, which is matched, is arranged with the second pin 4,
Second pin 4 passes through third through-hole 12a, push-and-pull rod through-hole 5a and fourth hole 12b and is movably connected in push-pull rod 5 for one group long-armed 1
On.
Drag-line hole 3a is equipped in the middle part of first pin 3, the drag-line 8 of 5 end of push-pull rod connection passes through the drag-line hole at 3 middle part of the first pin
3a is connected to handle 10.
Such as Fig. 3, push-pull rod 5 includes caliper interconnecting piece 13 and drag-line interconnecting piece 14, and the caliper interconnecting piece 13 is annulus knot
Structure, push-and-pull rod through-hole 5a are located at the middle part of circular ring structure, and drag-line interconnecting piece 14 is connected to drag-line 8.Drag-line 8 penetrates push-pull rod 5
At drag-line interconnecting piece 14 in hole, weld or rivet.
8 outer ring of drag-line is equipped with flexible outer tube 7, and 7 outer ring of flexible outer tube is equipped with position outer tube 9, and the setting of handle 10 is fixed
Position outer tube back-end.Protection outer tube of the flexible outer tube 7 as entire instrument, and can be used as the branch of entire product in product folding
Support.
Long-armed inside is equipped with hangnail.
The principle of work and power: using distinctive lever machinery structure, and long-armed balance pivot exists relative to the central axes of instrument
Be on position variation, when tissue forceps in the open state, central axes of the long-armed balance pivot apart from instrument are farthest, at this time
Close tissue forceps used in tractive force can effectively be transmitted to clamping tissue long-armed distal end, with folder close process into
Row, long-armed balance pivot is smaller and smaller apart from instrument central axes, and the torque of tractive force becomes smaller at this time, and organizes to long-armed distal end
Expansionary force it is constant or become larger so that required closing forces could be obtained by needing to give bigger tractive force, for this purpose, instrument increases
One position outer tube, for applying the power tightened to instrument center to galianconism, auxiliary completes the process that folder closes；The opening of instrument away from
From the summation that theoretically can achieve two long arm lengths, i.e., two long-armed angle maximums can open up into 180 degree, cooperation length
The surface of a wound of two long-armed total lengths can be closed by the hangnail on the inside of arm end.
Longer its of long-armed 1 length can press from both sides that the surface of a wound closed is bigger, and the distal end of galianconism 2 is connected to long-armed 1 middle part
Position pushes 10 push-pull rod 5 of proximal handle component and opens two long-armed 1, at this time long-armed 1 lever as long-armed 1 balance pivot
Pivot distance instrument central axes are farthest, and applying lesser power on push-pull rod just can make jaw start to be closed.
Fig. 4 a is that caliper opens schematic diagram；
Fig. 4 b is long-armed and galianconism connection cross-sectional view；Long-armed 1 and galianconism 2 on hole 17 and 16 internal diameter of axis and outer diameter activity connect
It connects.
Fig. 6 a, Fig. 6 b and Fig. 6 c are schematic diagram of the caliper as graduated scale state, be respectively from left to right pliers open to
The pattern that top view at 180 °, front view and Microendoscopic are observed.
Illustrating caliper and opening to 180 ° is caliper linear state longest state, takes the maximum value on top view to be at this time
27mm, cut-off rule 15 divide caliper 9 etc. to 3mm spacing, Microendoscopic we can use this equal part distance to measure endoscopy
Or the information such as size, position of lesion in operation, to provide good reference data for next step operation.
The maximum value max of binding clip is not limited only to 27mm as above herein, can be it is attainable in technical scope so numerical value,
Cut-off rule 15 can be not limited to 9 equal parts for the equal part distance of any numerical value.
Installation steps: being packed into clamp block 6 for two 2 hole device to hole of galianconism, is connected this three using the first pin 3；By push-pull rod 5
Hole device to hole is packed into two long-armed 1 and recycles the connection of the second pin 4, and two 2 distal bent positions of galianconism are respectively charged into two long-armed 1
Interstitial hole is connected herein by hinge in the present embodiment；Push-pull rod 5 is connect with zipper 8 then, loads onto flexible outer tube 7 outside zipper,
Position outer tube 9 is loaded onto outside flexible outer tube 7, Handleset is finally connect 7 with zipper 8 and flexible outer tube, at this time an alimentary canal
Tissue forceps assembles finish immediately.
Operating process: the surface of a wound is larger after normal ESD gastric operation needs to carry out surface of a wound closure, first row it is conventional into
Mirror prepares, and left hand thumb, index finger and middle finger are respectively protruding within three hole of handle by assistant, this instrument distal end is passed through interior peep by doctor
A wherein biggish channel for the road Jing Shuanqian mirror is sent into suitably partially to press from both sides the surface of a wound at the surface of a wound and be closed, becomes the big surface of a wound
Two small surface of a wound, in order to make the surface of a wound effectively closed, at this time assistant with the right hand by position outer tube 9 in proximal end to being pushed forward latching binding clip,
With reference to Fig. 5 state,；Successively the lesser surface of a wound is sutured one by one by hemostatic clamp conventional under another pincers road of endoscope simultaneously, until
This tissue forceps of the backed off after random of the whole sutures of the surface of a wound.
It is more convenient in order to perform the operation, a hemostatic clamp first can be made the both sides of tissue clamp closed position are first each, exit group
Knit the conventional surface of a wound closure operation of row again after clamping.
Tissue is closed in order to preferably press from both sides, increases corresponding hangnail on long-armed 1.
In order to effectively be closed the surface of a wound, this tissue forceps increases the closing course and the surface of a wound that position outer tube 9 is used to assist the surface of a wound
The surface of a wound is fixed after closure not slip from instrument easily.
The present invention provides a kind of alimentary canal tissue forceps, and there are many method and the approach for implementing the technical solution, with
It is only the preferred embodiment of the present invention described in upper, it is noted that for those skilled in the art, not
Under the premise of being detached from the principle of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the present invention
Protection scope.All undefined components in this embodiment can be implemented in the prior art.
