Detailed description of the invention
Describe the detailed description of the invention of a kind of rotatable hemostatic clamp of the present utility model in detail below in conjunction with accompanying drawing, but this utility model is not limited to these detailed description of the invention.
Embodiment one
Shown in Fig. 1-2, the rotatable hemostatic clamp of one of the present utility model, is characterized in that, comprises the coupling assembling 3 of clip 1, carrier 2, connection clip 1 and carrier 2;
Wherein, clip 1 comprises a pair intermediate plate 11 and the cinch tube 12 intermediate plate 11 can received wherein;
Carrier 2 comprises bourdon tube 21, the handle portion 22 be connected with bourdon tube 21 rear end, inner and can the mandrel 23 that reverses of good communication through bourdon tube 21, the leading section of mandrel 23 is connected with a pair intermediate plate 11, mandrel 23 rear end is connected with handle portion 22, and handle portion 22 can be reversed with moving mandrel 23 thus clip 1 is rotated relative to the bourdon tube 21 of carrier 2;
The front end of coupling assembling 3 is connected with the rear end of cinch tube 12, and the rear end of coupling assembling 3 is connected with the bourdon tube 21 of carrier 2;
The handle portion 22 of carrier 2 and mandrel 23 drive clip 1 to rotate by coupling assembling 3, and coupling assembling 3 can be out of shape when being subject to predetermined pull or destroy clip 1 is released.
Further, the front end of mandrel 23 can be provided with and pull 24, and mandrel 23 is connected with intermediate plate 11 by pulling 24.
Further, coupling assembling 3 comprises the resilient key 34 of the fixture 31 be connected with bourdon tube, the rotating shaft 33 be sheathed in fixture 31, axle sleeve 32, connecting bushing 32 and cinch tube 12; Axle sleeve 32 and cinch tube 12 can rotate around fixture 31 or rotating shaft 33; Rotating shaft 33 is provided with inner chamber, and the mandrel 23 of carrier 2 runs through the inner chamber by rotating shaft 33, and mandrel 23 is provided with the structure that coupling assembling 3 can be made to be out of shape when being subject to predetermined pull or to destroy.
Further, handle portion 22 comprises handle body 221, sliding handle 222, and the rear end of mandrel 23 is connected with sliding handle 222, and sliding handle 222 moves along handle body 221, and band moving mandrel 23 moves thus drives intermediate plate 11 to move.
In the present embodiment, the outside front ends of rotating shaft 33 is provided with step 331, the rear end of rotating shaft 33 is fixedly connected with fixture 31, its connected mode can be welding, bonding or interference fit etc., the rear end, inner side of axle sleeve 32 is provided with jut, makes axle sleeve 32 33 rotate not from wherein departing from around the shaft between the step 331 being arranged on to this jut matched in clearance fixture 31 and rotating shaft.
Should illustrate, mandrel 23 transmits for having good moment of torsion rope, pipe or the single tinsel or pipe that many one metal wires of performance are wound in, and its diameter is 0.2 ~ 1.0, and it can reach the moment of torsion transmission of 1:1.
Clip 1 also comprises a block piece 14, and it can make intermediate plate 11 open.Resilient key 34 is provided with at least one transverse lugs 341, and it runs through the corresponding hole or groove 321 and 121 that are provided with by axle sleeve 32 and cinch tube 12, and two parts are temporarily linked into an integrated entity.Mandrel 23 front end can arrange or assemble and pull 24, pin 13 runs through intermediate plate 11 rearward end and pulls the hole arranged on 24 to make to pull the front end of 24 to be connected with the rear end of intermediate plate 11, mandrel 23 is connected with sliding handle 222 again, and sliding handle 222 can move along handle body 221 and be with moving mandrel 23 to move together.When promote sliding handle 222 forward end and move and the intermediate plate forward end motion pulling 24 to connect with moving mandrel 23 front end time, mutually open at the effect lower clamping piece 11 of block piece 14, when rotatable handle portion 22, rotation is transmitted on clip 1 by the transmission by mandrel 23, makes clip 1 33 rotations around the shaft.Pull sliding handle 222 to the back-end, can with moving mandrel 23, pull 24 and intermediate plate 11 movement to the back-end make, in the part income cinch tube 12 of intermediate plate 11, to force intermediate plate mutually to be drawn close closed.
When doctor needs to use hemostatic clamp at endoscopic surgery, doctor first pulls sliding handle 222 that intermediate plate is closed to the back-end, to make hemostatic clamp smoothly by the pincers road of endoscope, after hemostatic clamp exposes the pincers road junction of endoscope by endoscope channel, doctor or nurse promote sliding handle 222 to the back-end and drive intermediate plate 11 to move to the back-end by the transmission of mandrel 23, under the effect of block piece 14, force intermediate plate 11 mutually to open, doctor or nurse's rotatable handle portion 22, rotation is delivered on clip 1 by the mandrel 23 good by transmitting torque, clip 1 is 33 rotations around the shaft, thus clip 1 can be made better to aim at focus, doctor pushes the clip 1 that bourdon tube 21 makes to open to the back-end and presses to focus, then sliding handle 222 is pulled to make intermediate plate bounce back to the back-end and close gradually to the back-end, by clamp tissue between two intermediate plates 11, when intermediate plate 11 can not again to cinch tube 12 rear end retraction time continue apply pulling force, pull 24 or pin 13 deform or destroy, make to pull 24 to be separated with intermediate plate 11, 24 are pulled to be designed with yielding or destructible structure, pin is that soft metal is as gold, silver or alloy, or for making that there is character destroyed under active force, that there is some strength nonmetallic materials macromolecular material as materials such as nylon, high density polrvinyl chloride, position that is yielding or that destroy the distortion or destructive power size that pull 24 or pin 13 controlled at about 20N ~ 80N, so that can be destroyed by pulling force that is singlehanded or both hands by doctor or nurse.Continuing to pull sliding handle 222 to transmit drive by mandrel 23 pulls 24 to move to the back-end, when pulling a 24 band moving mandrel 23 to make its abutment end 232 contact with the crooked place 342 of resilient key 34, due to resilient key 34 with pull 24 to be non-parallel assembling, and pull 24 with the gap, Inner footpath of bourdon tube 21 much smaller than the diameter of resilient key 34 or width, pull 24 resilient key 34 movement to the back-end can be driven to make its transverse lugs 341 be out of shape stretching or rupture failure to deviate from the hole that axle sleeve 32 and cinch tube 12 are provided with or groove 321 and 121, cinch tube 12 is separated with axle sleeve 32 thus, finally making clip 1 and carrier 2 be separated with coupling assembling 3 and discharge is stranded in the digestive tract of organism, the release that carrier 2 just completes clip 1 is withdrawn from by endoscope channel.
