Description
Technical field
The present invention relates to a kind of locking mechanism for the abdominal operation pincers, it is parts in the abdominal operation pincers, belongs to medical apparatus and instruments, mainly is applicable to the locking of claw beam when the abdominal operation pincers operate in the human abdominal cavity operation.
Background technology
Traditional abdominal operation pincers, comprise rotating shaft, but there is not the rotating shaft lockhole on the circumference of rotating shaft, and there is not to arrange the locking mechanism that matches each other, so, regulate rotating mechanism and can only control moving forward and backward of claw beam, bending and 360 ° of rotations, claw beam is locked in the relevant position in 360 ° of rotations, just there is thus following defective: during operation, it is by handle that the operator controls binding clip, realizes and the rotation of binding clip is rotation by handle, after the claw beam bending, the rotation of binding clip in human body is easy to run into the tissue of human body, hinder the rotation of binding clip, thereby not rotate with handle be can flexible 360 ° of rotations between claw beam and the handle, do not have what resistance, have easily relative sliding between the two, handle just can not well be controlled binding clip like this.
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 and can make that claw beam moves forward and backward, crooked and 360 ° of rotations, but owing to there is not to arrange the locking mechanism that matches each other, claw beam is locked, so still there is above defective in it in 360 ° of rotations in the relevant position.
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 not to arrange the locking mechanism that matches each other, it can not make claw beam 360 ° of rotations and in the relevant position locking, so still there is above defective in it equally.
Summary of the invention
The objective of the invention is to overcome existing above-mentioned deficiency in the prior art, can make claw beam in 360 ° of rotations, can also lock the locking mechanism that is used for the abdominal operation pincers of claw beam in a kind of reasonable in design, the operation and provide, so that after reaching the locking claw beam, claw beam and handle synchronous rotary do not have relative sliding when rotatable handle, thereby handle just can be controlled the purpose of binding clip well.
The present invention solves the problems of the technologies described above the technical scheme that adopts: the locking mechanism that should be used for the abdominal operation pincers comprises rotating shaft, it is characterized in that having in the described rotating shaft 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 is on same axis, and their centrage is vertical with the centrage of rotating shaft; Described locking positioning pin is connected with fixture block, and the rotating shaft lockhole is opened on the circumference of rotating shaft, and the coupling by locking positioning pin and rotating shaft lockhole realizes locking.Thus so that claw beam cervical region of the present invention can be 0 °～60 ° bendings when using, claw beam can 360 ° rotation and can be in any angle locking, it is easy to use and reliable to perform the operation.

The runner 43 of abdominal operation pincers is fixedly connected with rotating shaft 45 screw threads, and control rotating shaft 45 makes its 360 ° of rotations, thus 360 ° of rotations of control claw beam I, and namely runner 43 is controlled the claw beam I, regulating rotating mechanism 4 can 360 ° of rotation.
Referring to 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 is on same axis, and their centrage is vertical with the centrage of rotating shaft 45; Locating piece 53 is fixing with handle 6, and pintle hook lock 55 is socketed in also can be in fixture block 52 interior motions on the locating piece 53, 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 the 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, it is downward step site successively that channel position 3 523, channel position 4 524, channel position 5 525 are respectively, wherein channel position 5 525 is updip loxosises, its terminal upper surface is higher than the upper surface of channel position 1, pintle hook lock 55 can only be moved at these circulation canal 50 interior one-way circulations of doing, adverse movement can not occur.
Rotating shaft 45 of the present invention is fixed and is sleeved in the attaching nut 48 with central siphon 47, rotating shaft lockhole 451 is distributed on the head of rotating shaft 45 small ends 450 and is positioned on the circumference of rotating shaft 45, rotating shaft lockhole 451 is blind hole in the present embodiment, and rotating shaft lockhole 451 has six, in order to the quantity in hole is reached at most, increases thus latched position.In actual the use, latched position is The more the better; Six rotating shaft lockholes 451 in the present embodiment can satisfy the requirement of locking claw beam.
The self-locking of the present invention's energy can be controlled 360 ° of rotations of claw beam I, adjusting rotating mechanism 4.
Operation principle of the present invention is: the coupling of the rotating shaft lockhole 451 of six diverse locations realizes locking on the locking positioning pin 526 by fixture block 52 and rotating shaft 45 circumference.Namely when locking positioning pin 526 separates with rotating shaft lockhole 451, the claw beam I, regulating rotating mechanism 4 can 360 ° of rotation; When locking positioning pin 526 inserted rotating shaft lockhole 451, claw beam I, adjusting rotating mechanism 4 can not rotate.So locking mechanism 5 realizes locking work by up and down two different positions 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 circulates; When pintle hook lock 55 during in channel position one 521 position, locking positioning pin 526 separates with rotating shaft lockhole 451; When pintle hook lock 55 during in channel position 4 524 position, locking positioning pin 526 inserts rotating shaft lockholes 451.
During use, pintle hook lock 55 is initial position in the position of channel position 1, claw beam I, 360 ° of rotations of adjusting rotating mechanism 4 energy, click again insulation knob 51, 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, and at this moment locking positioning pin 526 inserts rotating shaft lockhole 451, and claw beam I, adjusting rotating mechanism 4 can not rotate; As want to allow claw beam I, adjusting rotating mechanism 4 rotate, click again insulation knob 51, 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, adjusting rotating mechanism 4 can rotate.
Below only be a specific embodiment described in this description, allly conceive equivalence or the simple change that described structure, feature and material are done according to patent of the present invention, be included in the protection domain of patent of the present invention.
