Description

Automatically vertical needle cavity mirror needle forceps

Technical field

The utility model relates to minimally invasive hysteroscopes, more particularly, to a kind of automatically vertical needle cavity mirror needle forceps.

Background technique

Minimally invasive endoscope-assistant surgery has many advantages, such as that wound is small, it is fast to restore, the hospital stays is short, it has also become the common hand of contemporary surgery Section, reason of equally being stopped blooding, be closed tissue in art etc., but since space is small, distance is remote, limit needle forceps (Needle Holder) clamps the flexibility of suture needle, therefore more at present simply using titanium folder or stapler hemostasis, closure tissue, thing In reality, the effect of needlework suture is better than titanium folder and stapler, and the adverse reaction of suture is also smaller than titanium folder and stapler.Patient's suture When be 1/3 intersection after being clamped in suture needle with needle holder, needle is vertically raised, tip alignment entry point, slightly wrist power are vertical Inserting needle simultaneously vertically goes out needle along the rotation of the radian of needle, so that suture (Fig. 1,2) is completed, it is such to operate in non-endoscope-assistant surgery not It is problem, but the suture needle ordinary water in endoscope-assistant surgery lies low in narrow lacuna, after patient holds needle pliering, is difficult accurately to press from both sides Firmly rear 1/3 in suture needle, and suture needle can be made to be vertically raised rapidly, even there is assistant's help also can not easily adjust seam The angle of needle is vertically raised its holding, result in suture it is not exquisite, inaccurate, time-consuming, or even because suture it is unsuccessful due to turn The drawbacks such as abdominal seriously affect the quality of sewing effect and operation.

The innovation and creation of many relevant surgical instruments, being provided to can be in the intracavitary condition for imitating open surgery, with more Mend the defect of non-open surgery, such as narrow space (foundation of pneumoperitoneum), untouchable (titanium folder, knot pusher, specimen bag).At present Intracavitary relevant device has: 1, knot pusher: its method is to knot in vitro, intracavitary push, increase external object enter it is intracavitary Number, complicated for operation, operating time is longer, and remote knot increases suture and slide number within the organization, and misoperation is then There is the risk of tearing tissue；2, stitching unstrument: expensive such as the Endo-Stitch in the U.S., complicated for operation, clinical application is not It is universal, and due to the limitation of collet opening, stitching unstrument can not carry out the suture of deep place, and plane suture is also difficult；3, titanium Folder: being widely used in the operation of closed duct, due to the limitation of its size and foreign body, can not mutually be equal to effect is directly tied Beauty, and in body cavity indwelling titanium folder easily cause postoperative untoward reaction, in imageological examinations such as patient postoperative CT, MRI there are artifact, The interference such as refraction influences tissue around observation, expensive to be not easy to promote although having absorbable biology folder at present； 4, the adverse reaction of needle forceps needle-holding stitching, suture is small, and needlework suture is more advantageous to special portion relative to titanium folder, stapler etc. The level of position is coincide, but needle difficulty is often found under hysteroscope, even success rate is not still high through special training person.

Summary of the invention

The purpose of this utility model is that for existing traditional needle forceps stand needle it is difficult and seriously affect surgical procedure and The defect of surgical quality provides a kind of automatically vertical needle cavity mirror needle forceps.

The utility model is equipped with upper pincers leaf and lower pincers leaf, and the bottom first half of the upper pincers leaf is set as and suture needle inner arc phase Corresponding dimpling portion has and upper pincers leaf axis oriented normal, the bar shaped sawtooth parallel with suture needle to be clamped, In in the dimpling portion of upper pincers leaf The latter half of upper pincers leaf is equipped with ellipsoid joint bolt, is equipped with connecting rod hole in the tail portion of upper pincers leaf；The lower pincers leaf Dimple corresponding with suture needle outer arc portion is set as at the top of first half, the dimple portion of lower pincers leaf have with lower pincers leaf axis oriented normal, The bar shaped sawtooth parallel with suture needle to be clamped is equipped with round+oval at the middle part of lower pincers leaf and upper pincers leaf joint bolt corresponding section Leaf glenoid is clamped under shape, is equipped with pull rod slot at the rear portion of lower pincers leaf；The upper pincers leaf joint bolt and the lower pincers leaf of round+ellipse close It saves the spherical front end of nest to fasten, upper pincers leaf joint bolt is rotated to horizontal position under the pulling in connecting rod hole, can be drawn into round+ellipse In the lower pincers leaf glenoid rear portion ellipse nest of circle；The pull rod slot is connect with connecting rod hole, the upper pincers leaf and lower pincers leaf Closed up by pull rod and opposite sliding, the front end of the pull rod are connect with connecting rod hole, the rear end of pull rod passes through pull rod slot, group At the automatically vertical needle cavity mirror needle forceps.

The utility model clamp to original needle forceps the improvement of sharp occlusal surface and plier joint, solves endoscope-assistant surgery Needle difficulty is found when middle suture and holds less than two problems of chucking power of needle sometimes, it can be flexible when remote endoscope-assistant surgery sutures Vertical needle simultaneously is reinforced holding needle force.The utility model has the suture operation that can simplify under hysteroscope, enhancing suturing skill horizontal, saves hand The art time reduces surgery cost, reduces the advantages that medical treatment cost, easy to produce and use, is conducive to popularization and industry from now on Change, greatly promote the development of endoscope-assistant surgery, improves quality of medical care.
