Abstract
The utility model discloses a kind of Minimally Invasive Surgeries to push away line hooking device, comprising: knot head, push rod and handle；The front end of push rod is arranged in the knot head, and the tail end of push rod is arranged in handle；The knot head is flat strip, and front is U-shaped in half opening, and is upturned, and rear portion is provided with reverse L type card hole.The utility model structure novel, it is easy to use, the knotting during minimally invasive endoscope-assistant surgery had both been facilitated, suture is also facilitated to adjust and unlock knot, to simplify complicated surgical procedure, while being readily cleaned disinfection, has been suitable for promoting the use of.
Description
Technical field
The utility model belongs to medical instruments field, in particular to a kind of to have the efficient of hooking function for Minimally Invasive Surgery
Knot pusher.
Background technique
Minimally invasive surgery technology is more and more applied in medical procedure, and the instrument performed the operation accordingly is also largely ground
Hair.Minimally invasive surgery technology passes through one or more tiny handle holes mostly and completes corresponding surgical procedure, to reduce operation
To the wound that patient generates, the recovery that patient is faster and better is allowed.
Exactly because Minimally Invasive Surgery is to complete surgical procedure by tiny handle hole, so suture in vivo will be non-
Normal difficulty, so that many surgical instruments are improved the difficulty sutured under doctor's hysteroscope by invention.For example, a kind of head end is
The knot pusher of " V " type is invented, for operative doctor to be knotted to push-in in vitro in vivo, to complete the suture to tissue.But this
During kind instrument knot, it is easy to there is the case where suture landing, it, cannot if colleague's suture is wound in vivo
It assists to arrange suture well, the instrument of profession is needed replacing, to waste valuable time in surgical procedure.
Chinese patent CN201120009972.9 discloses a kind of surgery hooking device and its mating puncture outfit, including hooking device
Ontology, hooking device inner core and diamond shape elastic metallic hook, it is characterised in that the hooking device ontology is hollow, inside setting hooking device
Elastic metallic hook is installed in inner core, the hooking device inner core bottom.But the surgery hooking device and its mating puncture outfit structure are excessively
Complexity is not easy cleaning and sterilizing.
It is therefore desirable to invent a efficient instrument with knot and hooking function, operative doctor is helped preferably to complete
It sutures and knots under mirror.
Summary of the invention
The utility model main purpose is to provide knotting hooking instrument under a kind of endoscope-assistant surgery, to reduce minimally invasive hysteroscope hand
The difficulty of surgeon's knot is ligatured and unlocked in art.
To achieve the goals above, the utility model uses following technical scheme: a kind of Minimally Invasive Surgery pushes away line hooking device, wraps
It includes: knot head, push rod and handle；The front end of push rod is arranged in the knot head, and the tail end of push rod is arranged in handle；The knot
Head is flat strip, and front is U-shaped in half opening, and is upturned, and rear portion is provided with reverse L type card hole.
Further, the front and rear of knot head is in 100 ° of ± 3 ° of angles.
Further, the vertical portion of L-type card hole is close to the front of knot head.
Further, line thread catcher is entirely pushed away to be made of stainless steel.
Further, knot head and handle are respectively welded on push rod.
This instrument includes the main component formed by the rigid structure material that can be sterilized, and main body has is grabbed by surgeon
The proximal handle held and for knotting and the distal end of hooking (unlocking knot) pushes away knot portion.
It pushes away line hooking device under hysteroscope using the utility model to ligature: since the distal end of main body pushes away knot portion with half
It is open and with rear portion in about 100 ± 3 ° of angle U-shaped structure, opening portion securely fixes suture, in knot mistake
It is not easy suture slippage occur in journey.Meanwhile about 100 ± 3 ° of angle is presented in knot head distal end U-shaped opening and the main body of instrument,
The angle of knot head front and rear portion makes the force distribution phase one of the force distribution of knot and the manual deep part knotting of operative doctor
It causes, rather than parallel state is presented with operation face in the strength angle of the near vertical of the past knot pusher formation, i.e. strength angle,
The drawing to the surface of a wound can be reduced, to reduce the damage to tissue.
Line hooking device is pushed away under hysteroscope with the utility model and Suture lines adjustment and unlocks knot: under knot head U-shaped structure
Side is a reverse L type card hole, performance when this structure thread entanglement can occurs in minimal invasive surgical procedures and need to unlock knot
Effect.In use, suture can be placed in the hook-shaped card hole of reverse L type, suture is slided in card hole, so as to adjust suture or is unlocked
Knot.
The utility model structure novel, it is easy to use, the knotting during minimally invasive endoscope-assistant surgery had both been facilitated, seam is also facilitated
Line adjusts and unlocks knot, to simplify complicated surgical procedure, while being readily cleaned disinfection, is suitable for promoting the use of.

Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art more fully understand technical solution of the present invention
Applying example, the present invention is described in further detail, it should be noted that in the absence of conflict, embodiments herein and
Feature in embodiment can be combined with each other.
As illustrated in fig. 1 and 2, Minimally Invasive Surgery pushes away line hooking device, including metal pushrod 8, knot head 9 and handle 10, knot head 9
8 front end rearward end of metal pushrod is respectively welded at handle 10.Entirely line thread catcher is pushed away all to be made of stainless steel material.
As shown in figure 3, knot head 9 includes two structures: the U-shaped half opening shape 11 in front and reverse L type card hole 12, difference
With the smooth gap 13 and 14 for facilitating suture 15 to enter.The U-shaped half opening shape 11 in front and push rod rear portion form about 100 ± 3 °
Angle (being in 80 ± 3 ° with front), to allow the force distribution phase of the force distribution of knot and the manual deep part knotting of operative doctor
Unanimously.
If 15 knot of suture being stuck in U-type groove by Fig. 4 when using pushing away line hooking device knot, sending to band and ligaturing at tissue i.e.
It can.Such as Fig. 5, when using originally pushing away line hooking device Suture lines adjustment or unlock knot, reverse L type card hole is caught on into suture 15, rearward or
Side drawing.
The above is preferred embodiments of the present invention, certainly cannot with this come limit the utility model it
Interest field, it is noted that for those skilled in the art, the technical solution of the utility model is carried out
Modification or equivalent replacement, without departure from the protection scope of technical solutions of the utility model.
