Description
Technical field
The present invention relates to the field of medical instrument technology, in particular to a kind of Clip Applier instrument.
Background technique
Laparoscopic clip applier is a kind of pliers that can clamp ligation clip in laparoscopic surgery and be closed ligation clip, abdominal cavity
Mirror Clip Applier can protrude into inside of human body from lesser notch, cooperate the operative site of laparoscopic visualization inside of human body, then
Clip Applier binding clip position is adjusted, ligation clip is allowed to be directed at blood vessel, then drives Clip Applier binding clip to be closed ligation clip by close handles.
The claw beam warp architecture for the laparoscopic clip applier that the country uses at present is the snake bone structure part of 9 superpositions by two one on the other
Pulling-on piece passes through hole to pull steering, and there are one the circular hole being used for across steel wire, steel wire, which passes through, to be turned to for snake bone structure part centre
After structure with control binding clip folding pull rod weld, in order to make control snake bone structure two pulling-on pieces up and down direction of motion phase
Instead, it is connected at the top of two pulling-on pieces on positive nut and reverse nut, in this way when realizing flexion torsion function, one
Forward, another pulling-on piece backward, can drive snake bone structure to be bent to pulling-on piece；However, positive and negative two nuts in above structure
And the corresponding stroke distances of each nut, will lead to bending turn round it is very big along claw beam axis direction size, when only use one holding

Clip Applier instrument provided by the embodiment of the present invention, for clamping ligation clip and being closed ligation clip, Clip Applier instrument
Ligation clip can be clamped and protrude into inside of human body from lesser notch, cooperate the operative site of laparoscopic visualization inside of human body, so
The binding clip position for adjusting Clip Applier afterwards, allows ligation clip to be directed at blood vessel, then by close handles, drives Clip Applier binding clip closure knot
Prick folder.The Clip Applier instrument includes: binding clip, Handleset, rotation torsion 6 and curves torsion 9, wherein binding clip is for clamping and being closed
Ligation clip；Handleset is connected with binding clip, when the binding clip position of Clip Applier instrument can allow ligation clip to be directed at blood vessel, handle group
Part is for driving binding clip to be closed ligation clip；Rotation is turned round 6 and is set between binding clip and Handleset, and rotation turns round 6 for controlling binding clip rotation
Turn, so as to so that binding clip has the function of 360 degree rotation；It curves torsion 9 to be set between rotation torsion 6 and Handleset, curves torsion 9
It is curved for controlling binding clip.That is, rotation torsion 6 is arranged in close to the one of Handleset in the torsion 9 that curves of the Clip Applier instrument
Side, i.e., closer to proximal end.
By above-mentioned set-up mode, when holding Handleset, it is real for the hand operation for holding Handleset that rotation turns round 6
The rotation of existing binding clip curves and turns round 9 and realize curving for binding clip for the hand operation for holding Handleset, in other words, when with one
When hand holds Handleset, torsion 9 can be curved by the index finger of this hand or the touching of other fingers, and due to curving torsion 9
Distance is close between rotation torsion 6, can also touch rotation using the same hand and turn round 6.
To sum up, only all operating functions on Clip Applier instrument can be realized with a hand, so as to solve
Conventional laparoscopic Clip Applier is difficult to meet the problem of realizing all operating functions on Clip Applier by one hand, above-mentioned Clip Applier in addition to
Outside the function of having driving binding clip 360 degree rotation, also have the function of that binding clip is made to be bent certain angle, which can basis
The adjustment of structure is set.Relative to traditional Clip Applier, which as much as possible can use metalwork, with this
Increase the service life of Clip Applier instrument, and the Clip Applier instrument does not have latch functions, it is possible to reduce more parts and structure,
Improve the stability of product.
Certainly, according to actual needs, above-mentioned Handleset specifically can be set to include fixed handle 1 and moving handle 2
Component, wherein fixed handle 1 remains stationary and for for palm contacts, moving handle 2 and the rotation of fixed handle 1 to connect
It connects and is used to that binding clip to be driven to be closed ligation clip, the grip position for holding Handleset can be similar to the posture for holding pistol.Such one
Come, in surgical procedure, operator is just as holding pistol, palm contacts fixed handle 1, and index finger or multiple fingers are passed through and moved
The ring portion 20 of fixed handle 2, then finger force pulls moving handle 2 to close to 1 direction of fixed handle, to pass through mobile hand
Handle 2 drives associated components movement, and so as to be closed ligation clip in laparoscopic procedures, blood vessel is clamped not bleeding.
In addition, above-mentioned rotation, which turns round 6 and curves torsion 9, can be set to cyclic structure, rotation, which is turned round 6 and curved, turns round both 9
Can be set on lateral wall convenient for finger touching contact portion, rotation turn round 6 on contact portion can be convenient finger effect for
The rotation of 6 stress is turned round in rotation, and curving the contact portion in torsion 9 can be convenient finger effect to stir to curve and turn round what 9 realization binding clips curved
Function.
Further, Handleset, which is connected with, curves the fixed sleeving 5 for turning round 9 for being set with, between fixed sleeving 5 and binding clip
Equipped with operation casing 3, operation casing 3 and fixed sleeving 5 are rotatablely connected and are used to rotate around the axis of fixed sleeving 5；Such as Fig. 1 institute
Show, fixed sleeving 5 and operation casing 3 are c-axially disposed on an axis A, and 6 proximal ends for being fixed on operation casing 3, operation are turned round in rotation
