Description
Technical field
The two-piece type that injury of human is touched is performed the operation the present invention relates to a kind of medical apparatus and instruments, more particularly to a kind of reduce
Pincers.
Background technology
Carried out in body in minimally invasive laparoscopic surgery, it is necessary to carry out traction and strong to large-scale organ-tissue in vivo,
It is easy to operative site there are enough spaces to be operated.Existing this operating forceps in currently available technology.These operating forcepses
Structure mainly include：Handle, pull bar, connecting plate, clamp, two clamps are hinged with two connecting plates respectively, and two connecting plates are hinged with pull bar,
Its drive jaw motion principle be：During mobile pull bar, two connecting plates are promoted to rotate, connecting plate drives clamp to rotate, and realizes that clamp is opened
Close.But this structure has a defect, when clamp opens, connecting plate is moved to outside in rotation so that connection front edge of board
It can protrude outer in clamp seat, so be easy for touching or scraping to other organ-tissues in surgical procedure, cause to organ group
The damage knitted.Rubber ring is easily damaged, it is necessary to often changed and safeguarded in general operating forceps claw beam position-limit mechanism in addition, is carried
High maintenance cost.
The content of the invention
Present invention mainly solves general operating forceps unreasonable structure in the prior art, be easy in surgical procedure touching or
Other organ-tissues are scraped, there is provided a kind of two panels for reducing and being touched to injury of human for the problem of damage is caused to organ-tissue
Formula operating forceps.
The technical solution adopted for the present invention to solve the technical problems is：A kind of two-piece type operating forceps, including two panels clamp,
Clamp is arranged on claw beam and covered on the clamp seat of front end, is provided with claw beam in claw beam set, claw beam front end is connected with clamp, the pincers
Folder includes pincers teeth portion and rotating part, and pull bar front end is provided with arm-tie, and the rotating part of two clamps is separately positioned on arm-tie both sides, in rotation
Jack-post is provided with the side of transfer part rotating part is rotatably connected on clamp seat, the another of portion center is rotated against in spin axis post
Side is provided with the middle of the first swivelling chute for being hinged and being rotated with arm-tie with arm-tie formation, rotating part and is provided with guiding rotating part
The arcuate socket of rotation, sets lead on hinged seat, and lead passes through arcuate socket and arm-tie.The clamp of operating forceps of the present invention leads to
Cross jack-post, arcuate socket, the first swivelling chute and moving forward and backward for pull bar is converted into rotation, it is achieved thereby that the opening and closing of clamp, this hair
It is bright to use connecting plate, it is to avoid connecting plate protrusion is outer in clamp seat during clamp opening and closing, easily contact and to human body
The problem of causing damage of tissue.Jack-post of the rotating part around side is rotated, and the of the arm-tie of pull bar and rotating part opposite side
One rotary shaft formation linkage, pull bar promotes rotating part to be rotated around jack-post, arcuate socket is under the limitation of lead when moving forward and backward
Guiding rotating part is rotated, and linear motion so is converted into arcuate movement, so as to realize the opening and closing of clamp.
As a kind of preferred scheme of such scheme, the rotating part is circle, and pincers teeth portion is connected with rotating part bias,
The jack-post is arranged on the side of nearly pincers teeth portion on rotating part, and the first swivelling chute is arranged on jack-post and rotates against the another of portion center
On side, into 90 ~ 120 degree of angles between the straight line where the line and pincers teeth portion of the first rotation groove center to jack-post center.This programme
The first swivelling chute that middle claw beam is forced away from clamping teeth portion is rotated rotating part around jack-post so that claw beam can be more laborsaving more smooth
Promotion under rotating part rotated.
As a kind of preferred scheme of such scheme, raised side the first swivelling chute of direction of the arcuate socket cambered surface.
As a kind of preferred scheme of such scheme, promotion post is provided with the side of the arm-tie one side, in arm-tie
The relative opposite side for promoting post of another side on be also equipped with promoting post, the rotating part of two clamps is separately positioned on arm-tie both sides
When, two promotion posts correspond to be engaged with the first swivelling chute on two rotating parts respectively, in the shifting centrally along pull bar of arm-tie
Dynamic direction is provided with elongated hole, and the lead passes through elongated hole.Set respectively on the two sides of arm-tie and promote post, and two push away
Dynamic post is correspondingly arranged on both sides respectively, and two such promotes first swivelling chute of the post respectively with being arranged on arm-tie both sides to be formed
It is hinged cooperation.Lead is relatively moved in elongated hole, and elongated hole, which is also functioned to, moves spacing effect to pull bar.
As a kind of preferred scheme of such scheme, the clamp seat is U-shaped structure, includes the supporting plate of both sides, two rotations
Transfer part, arm-tie overlapping are arranged between two supporting plates, and the lead is solid after the arcuate socket, the elongated hole of arm-tie of rotating part
Be scheduled between two supporting plates, be provided with the side of one side supporting plate with where it on sidespin flap jack-post it is relative one coordinate
Second swivelling chute, is also equipped with and jack-post relative one is matched somebody with somebody on sidespin flap where it on the opposite side of another side supporting plate
The second swivelling chute closed.Two rotating parts are arranged on behind arm-tie both sides between integral installation such as clamp two supporting plates of seat in this programme,
Jack-post on two rotating parts is hinged with the formation of two supporting plates respectively.Two the second swivelling chutes are located in two supporting plates and divided respectively
Wei Yu not both sides.
It is relative on claw beam set rear portion outer wall to be provided with two necks as a kind of preferred scheme of such scheme, block
Trench bottom is formed with window and covers intracavity inter-connection with claw beam, and two tangent planes are relatively set with the outer wall at the claw beam rear portion,
When claw beam is penetrated in claw beam set, the tangent plane of claw beam and planes align where the window of claw beam set have been embedded in claw beam in neck
Window and tangent plane are close in limited block, claw beam limited block bottom, and rubber ring is cased with outside claw beam limited block.To claw beam in this programme
It is movable to be limited, rotated while also prevent claw beam.And claw beam limited block is under the parcel of rubber ring, claw beam limit
Tightly paste firm window and tangent plane in position block bottom.
As a kind of preferred scheme of such scheme, fixed if being provided with arterial highway on the surface of the claw beam limited block
Groove, the rubber ring correspondence fixing groove quantity is also equipped with several, and rubber ring sleeve is on claw beam limited block, and rubber ring is embedded in
In fixing groove, claw beam fixed block is tightly pressed against in neck.Rubber ring sets son and has multiple and not set one in this programme, this
If if sample rubber ring is damaged in use, due to also there are other rubber rings, not interfering with to claw beam limited block
It is fixed.The groove being inserted in for rubber ring is provided with claw beam jacket wall between two necks.
It is an advantage of the invention that moving forward and backward for pull bar is converted into rotation by jack-post, arcuate socket, the first swivelling chute, tie
Structure advantages of simple, without using connecting plate, it is to avoid connecting plate protrusion is outer in clamp seat during clamp opening and closing, easily contact
With to tissue cause damage the problem of.
