Abstract
The utility model relates to a pair of minimally invasive knot tying forceps. The minimally invasive knot tying forceps comprise forceps handles, forceps heads and finger rings. The front ends of the forceps heads are two bent vertical sections, a groove is formed in the chelate face of the vertical section of the left side, the groove is perpendicular to the vertical sections of the forceps heads and serves as a through groove, the width of the groove is about one millimeter and the depth of the groove is about zero point eight millimeter. The minimally invasive knot typing forceps solve the problem that suture and knot tying are difficulty in endoscopic operations, enables the knot tying operation to be simpler and more convenient, and can shorten the operation time and lower the operation cost. By using the product, many operations which need to be opened originally are changed into endoscopic operations for treatment, and the endoscopic operations are the development trend of the surgical department, and therefore the application scope of the endoscope surgical department can be further expanded.
Description
Technical field
This utility model relates to a kind of surgical operating instrument, specifically a kind of micro-wound knotting tongs.
Background technology
19 beginnings of the century in the end of the century to 20, the attention of surgeons is transferred to gradually and how to be guaranteed under the prerequisite of therapeutic effect, the damage of Reduction surgery to body as far as possible, and endoscope-assistant surgery arises at the historic moment.Carrying out of Minimally Invasive Surgery promoted respectively ... the invention of (checking more) class mis instruments, is in fact all in the defect that makes up non-direct-view operation, as narrow space (foundation of pneumoperitoneum), untouchable (titanium folder, knot pusher, specimen bag) etc.But at present knotting apparatus used all cannot do easily ligation, tie etc. with the processing of tiing a knot as in direct-view operation.All there is defect separately in current knotting apparatus.As: Endo-Stitch stiching instrument, Ta Shi U.S. surgery company is that laparoscopic surgery is developed specially, this instrument is expensive, complicated operation, clinical practice is universal.Due to the restriction of chuck opening, Endo-Stitch stiching instrument can not be carried out the stitching that deep-seated is put, and plane is sewed up also difficulty.Separately have, titanium folder, is widely used in the operation of closed duct now, and due to restriction and the foreign body of its size, the effect that directly ties in cannot performing the operation with direct-view compares favourably.And indwelling titanium folder can cause postoperative untoward reaction in body cavity.The advantage of endoscope-assistant surgery is indubitable, but leave in vivo metal clip make us worry.When postoperative patient is expert at the imaging examinations such as CT, MRI, titanium is clipped in and exists to a certain extent interference, and as produced artifact, high light refraction etc., the observation of impact near tissue, interrogates not quite clear person when medical history and more easily produce false judgment.Although existing absorbable biological folder at present, expensive difficult popularization.Have been reported both at home and abroad, titanium be clipped in postcholecystectomy likely come off, mobile and form calculus to migration in bile duct, and reason does not fold up the improvement of seated position and operational approach with titanium and avoids completely.On the contrary, silk thread does not absorb, and the time that relatively can absorb fixture action time is long, and has avoided titanium to press from both sides the issuable adverse effect of health.So tiing a knot with silk thread is still a kind of tradition and reliable suture way.
But in Minimally Invasive Surgery, use silk suture, first because visual area is narrow and small, the operation of cannot directly tiing a knot; Second use other operating theater instruments auxiliary knottings such as mosquito forceps, easily clamp or pull line stripped thread, also inconvenience completes knotting operation.
Utility model content
The purpose of this utility model is just to provide a kind of micro-wound knotting tongs, to solve Minimally Invasive Surgery because not having special knotting apparatus to make the very inconvenient problem of knotting.
This utility model is achieved in that a kind of micro-wound knotting tongs, comprises clamp handle, binding clip and finger ring, and the front end of described binding clip is two bending vertical sections, clamping together of the described vertical section in left side, has a groove on face.
Described groove is vertical with described binding clip vertical section is also through slot; The width of described groove is 0.9-1.1mm, and the degree of depth of described groove is 0.7-0.8mm.
In described clamp handle, be provided with simple joint or doublejointed.
This utility model has solved in endoscope-assistant surgery and has sewed up, the difficult problem of tiing a knot, and makes knotting operation easier, can shorten operating time, reduces surgery cost.The use of this product, makes the operation that many scripts need to be opened can transfer endoscope-assistant surgery treatment to, and endoscope-assistant surgery is the development trend of surgery, can further expand thus the suitable application area of chamber mirror surgery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this ligaturing forceps comprises clamp handle 2, binding clip 3 and finger ring 1, and the front end of binding clip 3 is two bending vertical sections 4 that interlock clamps relatively, and the about 2cm of length of vertical section 4 has a groove 5 clamping together of the vertical section in left side on face.This groove 5 is vertical with binding clip vertical section 4 and on vertical section, connect one-tenth through slot.The width of groove 5 is about 1mm, the about 0.8mm of the degree of depth of groove.
Ligaturing forceps can be simple joint, can be also doublejointed, in clamp handle 2, is provided with simple joint or doublejointed.
Using method of the present utility model is: during knotting, left hand is held line, with ligaturing forceps, clamps stitching thread, allows stitching thread be positioned at groove 5, and the right hand is held ligaturing forceps, slides sutural toe-in is pushed to root and urgently can be completed a knotting operation.This utility model is sent toe-in into the mode of operation in body with hand operated before having avoided, and has improved the operative incision little knotting causing the not easy to operate situations such as inhomogeneous or Slipped Clove Hitch of exerting oneself, thereby has been particularly suitable for the operation knotting under little otch and chamber mirror.This utility model can be simplified knotting operation, is widely used in needing the operation occasion of titanium folder, can reduce surgery cost, makes many open operations transfer endoscope-assistant surgery to.The structural design of the growth of binding clip vertical section, makes the push operation of toe-in more convenient flexibly.
