Description
Technical field
The present invention relates to a kind of locking mechanism for abdominal operation pincers, it is parts in abdominal operation pincers, belongs to medical apparatus and instruments, is mainly applicable to the locking of claw beam during abdominal operation pincers operation in human abdominal cavity operation.
Background technology
Traditional abdominal operation pincers, comprise rotating shaft, but rotating shaft does not circumferentially have rotating shaft lockhole, and do not have to arrange the locking mechanism matched each other, so, regulate rotating mechanism can only control the movable of claw beam, bend and 360 ° of rotations, claw beam can not be made to lock in relevant position while 360 ° rotate, just there is following defect thus: during operation, it is by hands handle that operator controls binding clip, and the rotation of binding clip is realized by the rotation of handle, after claw beam is bending, the rotation of binding clip in human body is easy to the tissue encountering human body, hinder the rotation of binding clip, thus the i.e. flexible 360 ° of rotations of energy between claw beam and handle are not rotated together with handle, there is no any resistance, easily there is relative sliding between the two, such handle just well can not control binding clip.
China Patent No. 2010102346538 discloses the patent of invention that a kind of name is called " multifunctional bendable forceps for laparoscopic surgeries ", it comprises interconnective claw beam and Handleset, claw beam comprises draw-in bar, pincers sheath pipe and pincers core, Handleset comprises handle and regulates rotating mechanism, regulate rotating mechanism claw beam can be made to move forward and backward, bend and 360 ° of rotations, but owing to there is no to arrange the locking mechanism matched each other, claw beam can not be made to lock in relevant position while 360 ° rotate, therefore still there is above defect in it.
China Patent No. 002187582 discloses the utility model patent that a kind of name is called " surgical forceps for abdominoscope ", it also comprises interconnective claw beam and Handleset, it can make claw beam move forward and backward, but owing to there is no to arrange the locking mechanism matched each other, it can not make claw beam rotate at 360 ° and lock in relevant position equally, therefore it still exists above defect.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency existing in prior art, and the locking mechanism for abdominal operation pincers that claw beam can be made while 360 ° rotate can also to lock claw beam is provided in a kind of reasonable in design, operation, so that after reaching locking claw beam, claw beam and handle synchronous rotary do not have relative sliding when the handle is rotated, thus handle just can control the object of binding clip well.
The present invention solves the problems of the technologies described above adopted technical scheme: this locking mechanism being used for abdominal operation pincers comprises rotating shaft, it is characterized in that described rotating shaft has rotating shaft lockhole; Also be provided with fixture block and locking positioning pin, the centrage of described fixture block, locking positioning pin and rotating shaft lockhole on the same axis, their centrage and the central axis of rotating shaft; Described locking positioning pin is connected with fixture block, and rotating shaft lockhole is opened in rotating shaft circumferentially, realizes locking with mating of rotating shaft lockhole by locking positioning pin.When making thus to use, claw beam cervical region of the present invention can bend at 0 ° ~ 60 °, and claw beam can also in any angle locking, can be performed the operation easy to use and reliable in 360 ° of rotations.

See Fig. 1-Fig. 8, the present invention includes insulation knob 51, fixture block 52, locating piece 53, spring 54, pintle hook lock 55, locking positioning pin 526, circulation canal 50 and rotating shaft 45, locating piece 53 is threaded with front hand grip 62.
The centrage of fixture block 52 of the present invention, locking positioning pin 526 and rotating shaft lockhole 451 on the same axis, their centrage and the central axis of rotating shaft 45; Locating piece 53 is fixed with handle 6, and pintle hook lock 55 is socketed on locating piece 53 and also can moves in fixture block 52, and spring 54 is between locating piece 53 and fixture block 52, and the upper end of fixture block 52 is fixed with insulation knob 51.
The middle part of fixture block 52 of the present invention is provided with a circulation canal 50, and the motion of pintle hook lock 55 in this circulation canal 50 is one-way circulation motion; In the present embodiment, circulation canal 50 has five positions, channel position 1 is initial position, channel position 2 522 is a updip loxosis, then, channel position 2 522 both by a downward step to channel position 3 523, channel position 3 523, channel position 4 524, channel position 5 525 are respectively downward step site successively, wherein channel position 5 525 is updip loxosises, its end upper surface is higher than the upper surface of channel position 1, make pintle hook lock 55 can only do one-way circulation motion in this circulation canal 50, there will not be adverse movement.
Rotating shaft 45 of the present invention is fixed with central siphon 47 and is sleeved in attaching nut 48, rotating shaft lockhole 451 is distributed on the head of rotating shaft 45 small end 450 and is positioned at rotating shaft 45 circumferentially, rotating shaft lockhole 451 is blind hole in the present embodiment, and rotating shaft lockhole 451 has six, to make the quantity in hole reach maximum, increase latched position thus.In actual use, latched position is The more the better; Six rotating shaft lockholes 451 in the present embodiment can meet the requirement of locking claw beam.
Energy self-locking of the present invention, can control claw beam I, regulate 360 ° of rotations of rotating mechanism 4.
Operation principle of the present invention is: realize locking by the mating of rotating shaft lockhole 451 of the locking positioning pin 526 of fixture block 52 and rotating shaft 45 circumferentially six diverse locations.Namely when locking positioning pin 526 separates with rotating shaft lockhole 451, claw beam I, the 360 ° of rotations of adjustment rotating mechanism 4 energy; When locking positioning pin 526 inserts rotating shaft lockhole 451, claw beam I, adjustment rotating mechanism 4 can not rotate.So locking mechanism 5 realizes locking work by two different positions up and down of fixture block 52, and two diverse locations of fixture block 52 are controlled by pintle hook lock 55.
Because the motion of pintle hook lock 55 in fixture block 52 is circulation; When pintle hook lock 55 is in channel position one 521 position, locking positioning pin 526 separates with rotating shaft lockhole 451; When pintle hook lock 55 is in channel position 4 524 position, locking positioning pin 526 inserts rotating shaft lockhole 451.
During use, pintle hook lock 55 is initial position in the position of channel position 1, claw beam I, the 360 ° of rotations of adjustment rotating mechanism 4 energy, click insulation knob 51 again, pintle hook lock 55 arrives channel position 4 524 from channel position 1 through channel position 2 522, channel position 3 523, and be parked in channel position 4 524, at this moment locking positioning pin 526 inserts rotating shaft lockhole 451, and claw beam I, adjustment rotating mechanism 4 can not rotate; Allow claw beam I, adjustment rotating mechanism 4 rotate as wanted, click insulation knob 51 again, pintle hook lock 55 arrives channel position 1 from channel position 4 524 through channel position 5 525, and be parked in channel position 1, at this moment locking positioning pin 526 separates with rotating shaft lockhole 451, and claw beam I, adjustment rotating mechanism 4 can rotate.
Below be only a specific embodiment described in this description, all equivalences of doing according to structure, feature and the material described in inventional idea of the present invention or simple change, be included in the protection domain of patent of the present invention.
