Inside be equipped with traction fiber, one end of traction fiber is fixedly connected with to be slidably matched with the excitation matched manipulation ring of window, manipulation ring
In on handle, protective case and mobile hand handle are movably installed on the traction fiber protection sheath, mobile hand handle is fixed on protective case
One end, the activity that is provided between mobile hand handle and handle are placed in the brake on traction fiber protection sheath, the traction fiber protection
The other end of sheath has connecting bridge, and traction fiber is protected sheath to be removably connected with excitation portion by connecting bridge, set in the excitation portion
It is equipped with the upper gripper jaw being detachably connected with traction fiber, small clamping jaw and lower clamping jaw, small clamping jaw is between upper gripper jaw, lower clamping jaw.
Preferably, the clamping end of the upper gripper jaw, small clamping jaw and lower clamping jaw is respectively positioned on the outside in excitation portion, and small clamping jaw
Length is less than the length of upper gripper jaw or lower clamping jaw.
Preferably, the upper gripper jaw, small clamping jaw and lower clamping jaw are that metal material is made.
Preferably, one end that the handle is connect with traction fiber protection sheath is cone, and handle is equipped with and is located at excitation
The screwed ring of window one end.
Preferably, the brake includes multiple clip tooths, and multiple clip tooths are alternately folded on traction fiber protection sheath.
This programme, which not only has uniformly, symmetrically to grasp after implementation, needs the two sides mucous membrane tissue that is closed, the surface of a wound
Completely, smooth, and can be avoided mucous membrane tissue oedema varus, the surface of a wound fitting for causing folder to close is bad, additionally it is possible to avoid roomy wound
Face presss from both sides the situation for closing diameter deficiency.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, the segmented applied under a kind of novel digestive endoscopy grasps closure instrument, including handle 1, hand in advance
Handle 1 is equipped with excitation window 2, and one end of handle 1 is connected with traction fiber protection sheath 7, and the other end of handle 1 has handle ring 6, traction
The inside of silk protection sheath 7 is equipped with traction fiber 4, and one end of traction fiber 4 is fixedly connected with and the excitation matched manipulation ring 3 of window 2, behaviour
Control ring 3 is snug fit on handle 1, and protective case 10 and mobile hand handle 14, mobile hand handle are movably installed on traction fiber protection sheath 7
14 are fixed on one end of protective case 10, and the activity that is provided between mobile hand handle 14 and handle 1 is placed on traction fiber protection sheath 7
Brake 5, traction fiber protect the other end of sheath 7 to have connecting bridge 8, and traction fiber protection sheath 7 is removably connected with by connecting bridge 8
Excitation portion 9 is provided with the upper gripper jaw 11 being detachably connected with traction fiber 4, small clamping jaw 12 and lower clamping jaw 13, small folder in excitation portion 9
Pawl 12 is between upper gripper jaw 11, lower clamping jaw 13.
In present embodiment, the clamping end of upper gripper jaw 11, small clamping jaw 12 and lower clamping jaw 13 is respectively positioned on the outside in excitation portion 9,
And the length of small clamping jaw 12 is less than the length of upper gripper jaw 11 or lower clamping jaw 13.
In present embodiment, upper gripper jaw 11, small clamping jaw 12 and lower clamping jaw 13 are that metal material is made.
In present embodiment, one end that handle 1 is connect with traction fiber protection sheath 7 is cone, and handle 1 is equipped with and is located at
Excite the screwed ring of 2 one end of window.
In present embodiment, brake 5 includes multiple clip tooths, and multiple clip tooths are alternately folded on traction fiber protection sheath 7.
In the use of the present invention, first removing brake 5, mobile hand handle 14 is pulled to make protective case 10 towards handle 1 later
Direction it is mobile, at this point, excitation portion 9, upper gripper jaw 11, small clamping jaw 12 and lower clamping jaw 13 are stretched out out of protective case 10, later, return
It draws manipulation ring 3 to make upper gripper jaw 11, the closure of small clamping jaw 12 first grasping surface of a wound side tissue, does not discharge, can operate repeatedly, determine this
It is pulled to surface of a wound opposite side after side grasping tissue is satisfied, grasps other side tissue, continuing to pull back after confirmation is satisfied manipulates ring 3 and arrive
Bottom is closed successfully with lower clamping jaw 13, and later, being pushed forward manipulation ring 3 separates traction fiber protection sheath 7 with excitation portion 9, and excitation portion 9 is
It stays at closure, traction fiber protects sheath 7 to handle by sharp instrument.
Different from traditional two point form closure, segmented closure instrument first clamps side tissue, is grasped, can be lifted in advance
And activity, the hand-held part of assistant, which is only clamped, at this time is not closed, traction to the surface of a wound other side, then clamps other side group with closure instrument
It knits, finds position balanced as far as possible and be closed, assistant carries out closed procedure at this time, completes the use of closure instrument.
