Description
Technical field
Technical field of medical instruments is the utility model is related to, is a kind of special purse-string suture device of laparoscope specifically.
Background technology
In surgical operation, since invention the 1960s first staple class product, Medical stapler into
For a kind of medicine equipment indispensable in auxiliary edge of a knife sewing process.With the development of medical science and grinding for medical device product
Hair, increasing staple class product is applied to clinic, and the use range of such product has been directed to gastrointestinal surgery, outside liver and gall
The fields such as section, thoracic surgery, Urology Surgery, gynemetrics, turn into one of essential instrument of doctor.Doctor is doing alimentary canal end end
When coincideing, operated commonly using tube type anastomat, just purse string suture must be carried out to tissue to be implanted at one end before coincideing
The ailhead of tube type anastomat, can firmly to be ligatured after center-pole is inserted, it then could implement engaging tissue operation.At present
Many doctors are manual suture pockets, can not so ensure whether the amount of tissue at pocket is suitable, if residual tissue excessively can
Cause stapler percussion failure；If very few, the risk of fistula is had after coincideing.Therefore, in use, it is more and more
Doctor sutures pocket using purse-string forceps, and the quality of the apparatus performance directly affects operation and carried out, and surgical effect is played very
Important effect.The purse-string forceps actually used at present mainly have two types, the manual purse-string forceps of linear pattern all-metal, linear pattern seam
The automatic purse-string forceps of nail type.For the manual purse-string forceps of linear pattern, it is typically made up of jaw, connecting rod, clamp handle, first with pincers during use
Mouth clamps tissue, and then tight locked groove mouth, tissue can be naturally clamped, and part tissue is squeezed into the space of notch,
Now out of, one end of purse-string forceps penetrates purse-string forceps with the suture needle of a foot section brought line top circular hole, extracted from opposite side, so
Pin turns around afterwards, then is passed out of purse-string forceps bottom circular hole, and finally two terminations of purse wire knot in side.Traditional lotus
Bag clamp head part is typically in 90 ° or hexagonal angle, angle can not be adjusted arbitrarily with vice body.In deeps such as abdominal cavity, pelvic cavity in use, due to
Narrow space, penetrates and extracts that pocket pin is extremely difficult, easily the histoorgan around damage.
Patent CN2014204440576, discloses a kind of variable purse-string forceps of head angle, including left handle, right handles,
Left binding clip and right binding clip, wherein, it is rotatablely connected between the left handle and right handles, the left handle, right handles pass through respectively
Rotation positioning device is rotatablely connected with the left binding clip and right binding clip respectively, and the rotation positioning device can make binding clip relative to hand
Handle rotates, and can be positioned in its slewing area, and realizing purse-string forceps, basis is actually needed adjusting angle in use
Degree.But purse-string forceps design can be used only in abdominal, can not be used under laparoscopic surgery.Secondly, the purse-string forceps make
With jaw by, it is necessary to carry out suture needle operation, suture needle easily changes the relative angle of binding clip and handle during threading a needle after clamp tissue
Degree, causes difficulty of threading a needle.

Through hole 21, the quantity of through hole 21 is 2-6, and the axis of through hole 21 is vertical with the axis of rotating shaft 14 and is arranged on same vertical face,
The locking steel ball 22 contacted with the inclined-plane 15 is provided with through hole 21；When axis direction of the inner sleeve 13 along rotating shaft 14 is inwardly slided
When dynamic, the lower surface of locking steel ball 22 rolls on inclined-plane 15 until the upper surface of locking steel ball 22 and the inwall of sleeve 12 connect
To touch, the thrust of inner sleeve 13, the elastic force on inclined-plane 15, three force balances of elastic force of the inwall of sleeve 12 lock locking steel ball 22,
It can not now be relatively rotated between inner sleeve 13 and sleeve 12.
Back-moving spring 23 is provided between the end face of the inner sleeve 13 and the bottom surface of sleeve 12, back-moving spring 23 is enclosed on rotating shaft 14
On, one end of back-moving spring 23 and the end face movable contact of inner sleeve 13, the bottom surface movable contact of the other end and sleeve 12.Reset bullet
The elastic force that spring 23 provides causes locking steel ball 22 to keep the state to unlock.
Further, the quantity of the ball chamber 17 is 2-6, and the quantity of the detent 16 is 12, when clamp 1 with
When plane where clamp handle 2 is in 30 °, 60 °, 90 °, 120 °, detent 16 it is corresponding with ball chamber 17 by clamp 1 with clamp handle 2
Between angle fix.
Further, the end face of the inner sleeve is provided with projection 24.When left and right binding clip clamps, be inside enclosed in the presence of clamp to
Slided in sleeve and lock locking steel ball, projection 24 contacts with the bottom surface of sleeve, directly acts on the chucking power of clamp handle
Clamp, avoid the clamping power of handle unstable.
The clamp angle of the present embodiment can be adjusted according to service condition, when clamp clamps, between clamp and clamp handle
Angle locking, the operation that now carries out threading a needle will not change the angle of clamp；After unclamping clamp, clamp angle recovers adjustable nodular
State.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
Art personnel, on the premise of the utility model method is not departed from, some improvement and supplement can also be made, these are improved and supplement
Also it should be regarded as the scope of protection of the utility model.
