Description

Deep knotting forceps

Technical field

The invention belongs to medical instruments field, relate to a kind of deep knotting forceps.

Background technology

Along with the development of chamber mirror technology, the chamber mirror is more and more extensive in the application of breast abdominal surgery, usually applies disposable material when operation, the tissues such as the closed blood vessel of closer, bronchus, esophagus and bile duct, and its shortcoming is: 1, expensive; 2, be subject to sometimes the restriction of angle, can't apply.

Increasing doctor selects to apply the deep part knotting technology, can overcome the shortcoming of disposable material, the integral body of current Knotter applicable deep part mostly is direct rod shape, front end at wire twister offers one or two wire hole, when carrying out deep part knotting, need at first the knotting line be stretched into to wire hole, promoting wire twister is organizing deep to complete the knotting process, its complex operation, the knotting weak effect, and because profile and the rear portion, joint of direct rod shape are wider to the distance between handle, be not suitable for the operation of the little otch of chamber mirror, very limited to the control ability of deep knot.

Summary of the invention

In order to solve the above-mentioned technical problem existed in background technology, the invention provides the deep knotting forceps of effective, simple, convenient, the quick and applied range of a kind of deep part knotting.

Technical solution of the present invention is: the invention provides a kind of deep knotting forceps, comprise binding clip, its special character is: be provided with the groove for line ball on described binding clip.

Above-mentioned groove is arranged at the leading section of binding clip.

The setting party of above-mentioned groove is nonparallel to the caliper direction with binding clip.

Above-mentioned groove is one or more.

Above-mentioned deep knotting forceps also comprises the finger circle connecting rod be connected by movable joint section with binding clip; Described finger circle connecting rod is curved.

Above-mentioned binding clip and movable joint section are 0-90 °.

The leading section of above-mentioned binding clip also is provided with the wire hole that is parallel to groove, and described wire hole is one or two.

When above-mentioned wire hole is two, described wire hole is arranged at respectively in two binding clip branches of binding clip.

Above-mentioned deep knotting forceps also comprises the locking tooth be arranged on finger circle connecting rod.

Advantage of the present invention is:

The invention provides a kind of deep knotting forceps, be provided with special groove and offer wire hole at two binding clip front ends respectively on binding clip, during knotting, can select application to use special groove or fairlead to be gone between, carry out deep part knotting under chamber mirror and direct-view in surgical operation, and the various actions that coordinates deep vessels to clamp, the operation technique that can make easy to use is meticulousr, rapid, reliable.Simultaneously, the present invention is narrower to handle at the rear portion, joint, is applicable to the operation of the little otch of chamber mirror, and the front portion, joint is provided with the binding clip of 0-90 degree, and the scope of application is boundless, can meet the demand of different depth knotting.

The accompanying drawing explanation

Fig. 1 is the structural representation of deep knotting forceps provided by the present invention;

Fig. 2 is the binding clip part structure for amplifying schematic diagram of deep knotting forceps of the present invention;

Wherein:

The 1-binding clip; 2-movable joint section; 3-refers to enclose connecting rod; 4-refers to circle; The 5-groove; The 6-wire hole; 7-locking tooth.

The specific embodiment

Referring to Fig. 1 and Fig. 2, the invention provides a kind of deep knotting forceps, comprise binding clip 1, be provided with the groove 5 for line ball on the leading section of binding clip 1, the setting party of groove 5 is nonparallel to the caliper direction with binding clip 1, preferably is vertical configuration, groove 5 is not limited to one, if a plurality of, between groove 5, be parallel to each other, more convenient block or suppress lead-in wire.

Deep knotting forceps provided by the present invention also comprises the finger circle connecting rod 3 be connected by movable joint section 2 with binding clip 1; Referring to that circle connecting rod 3 is different from traditional straight-bar mode, is curved.In surgical operation, carry out under chamber mirror and direct-view during deep part knotting, by compacting and refer to the finger circle 4 that circle connecting rod 3 is connected, the more deep that makes binding clip 1 the stretch into tissue operation of tiing a knot, contribute to the operation technique when the little otch of chamber mirror, very easy to use.

Binding clip 1 can be set to different angles according to different actual needs from movable joint section 2, such as 0-90 °, 0-180 ° etc.

The leading section of binding clip 1 also is provided with the wire hole 6 that is parallel to groove 5, and wire hole 6 is one or two, and when wire hole 6 is two, wire hole 6 is arranged at respectively in two binding clip branches of binding clip 1.

Deep knotting forceps provided by the present invention also comprises the locking tooth 7 be arranged on finger circle connecting rod 3, and it has fixed the position of binding clip.

Although the present invention selects the selected wire hole 6 of groove 5 and traditional ligaturing forceps to be pushed for the knot to accomplishing fluently, the two has essential distinction, just is that groove 5 is without threading, directly lead-in wire is suppressed and sent, when binding clip stretches into while organizing deep, direct pressing lead-in wire knot, simple and reliable; And wire hole 6 is for connecting line, its process is more loaded down with trivial details.The present invention is arranged at groove 5 and wire hole 6 on binding clip 1 simultaneously, has enriched the function of existing ligaturing forceps, make its have threading send the knot or line ball send the knot two kinds of functions.
