The specific embodiment
Referring to Fig. 1, coordinate referring to Fig. 2, Fig. 3, Fig. 4, the closed apparatus of endoscope-use band running fire metal clip of the present utility model, comprise handle 3, sheath pipe 2 and operate portions 1 that order is connected, operate portions 1 wherein comprises:
One sheath 11, be provided with the cavity of axial perforation in it;
One is arranged on and pushes away seat 12 in the sheath cavity, and this pushes away seat 12 rear ends and pushes away silk 4 by one and be connected with handle 3, and operating grip pushes away silk and can promote to move forward.
A plurality of metal clips 13 that are arranged in the sheath cavity, a plurality of metal clips are socketed connected from beginning to end, its last metal clip with push away seat 12 sockets and be connected.
One nipper 14, this nipper rotatably is connected with the front end of sheath, and is connected with handle by two wire drawings 5, and operating grip pulls wire drawing can make the nipper closure;
Cooperation is referring to Fig. 6, and metal clip 13 integral body in this utility model are the U-shaped structure of both sides symmetry, comprises U-shaped bottom 131, and the flap 132 sequentially extended along both sides, U-shaped bottom, thick arm 133 and microbrachia 134; The U-shaped bottom of previous metal clip may be stuck between two microbrachias of a rear metal clip, and is pressed on two microbrachias of a rear metal clip by two flaps of previous metal clip.Cooperation is referring to Fig. 7, and the seat 12 that pushes away in this utility model is provided with a U-shaped socket 121, and the U-shaped bottom of described metal clip can be inserted in this U-shaped socket, and by two flap stop bits.Two microbrachias 134 of metal clip 13 are respectively crooked to the inside arc, and can be crooked in opposite directions under external force, after two microbrachias bending simultaneously, 90 degree, realize closed.
Cooperation is referring to Fig. 5, and the nipper 14 in this utility model consists of symmetrically arranged two calipers 141 and two clamp handles 142, and clamp handle is fixedly connected on the rear end of caliper.The front portion of sheath 11 is provided with minor axis 111, and clamp handle 142 rotatably is connected with minor axis 111 by axis hole 1421; Clamp handle 142 rear ends are connected with an end of wire drawing 5, and the other end of wire drawing 5 is connected with handle, and operating grip pulls wire drawing to make the minor axis rotation of clamp handle along sheath, thereby realize the closure of nipper.Caliper 141 is provided with left and right two row's pincers teeth 1411,1412, and centre is provided with groove 1413, and front end is provided with chopping block 1414, and this chopping block is provided with aduncate arcwall face, and groove 1413 forms the passage of metal clip, and chopping block 1414 forms the guide function body that makes the metal clip closure.
But operating process principle accompanying drawings of the present utility model is as follows:
During use, at first utilize nipper 14 to capture destination organization, now two wire drawings 5 synchronously pull back, and drive nipper 14 closures.
Then, from the interior release metal clip 13 of nipper 14, and complete closure.Concrete transmittance process is, pushes away silk 4 and drives and push away seat 12, pushes away seat 12 and drives last metal clip, then drive to the current metal clip discharged successively.Metal clip is by from the interior release of sheath 11, nipper 14 gripping destination organization now, metal clip 13 enters in the groove 1413 of nipper and thrusts destination organization, finally prop up chopping block 1414, continue to push hard and push away silk 4, make after the crooked closures of microbrachia 1411,1412 arcwall faces along chopping block 1414 of front end metal clip 13 to complete to discharge.If when nipper captures destination organization, effect is undesirable, again capture after can making it open, again by joystick 3 locking nippers, guaranteed to capture the accuracy of destination organization after confirmation.
This utility model adopts the principle of similar stapler, therefore can reach the purpose of discharging continuously many all-metal folders, and closure effect is reliable.In addition, nipper possesses repeatedly the function opened and closed, and has made up current endoscope and only can discharge one piece of metal clip, weak point that grasping force is little with metal clip.
