Fig. 2 is local enlarged diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and embodiments, this utility model is elaborated.
Please refer to shown in Fig. 1, under a kind of peritoneoscope of this utility model, use the preferred embodiments of biopsy forceps to comprise: two the finger ring handles 1 that cooperatively interact, tong arm 2, draught line 3, rotary connector 4, binding clip 5, connecting rod 6, chute 7, axle core 8, stick 9 and stick control device 10.The upper end of described finger ring handle 1 is fixedly connected with the first end of tong arm 2, and the second end of described binding clip 5 is connected with the second end of tong arm 2 by rotary connector 4.
Please refer to shown in Fig. 2, described rotary connector 4 be a pair of the first engaging lug 41 protruding on the second end by binding clip 5 and a pair of the second engaging lug 42 protruding on tong arm 2 second ends by two set bolts 43 rotatable be fixedly connected with form.
Described binding clip 5 comprises tool rest 51 and cutter head 52, and described tool rest 51 is fixedly connected on the first end of binding clip 5, and described chute 7 is arranged at binding clip 5 inside, and described connecting rod 6 is fixed in binding clip 5 by axle core 8, and described connecting rod 6 can rotate taking axle core 8 as the center of circle.The first end of described connecting rod 6 is connected with the afterbody pivotable of cutter head 52, the second end of described connecting rod 6 is positioned at chute 7, and the second end of described draught line 3 and the second end of described connecting rod 6 are connected and control by the rotation of control connection bar 6 movement of cutter head 52.
Specifically, on described binding clip 5, have the chute 7 of a strip, described connecting rod 6 is fixed on the inwall of chute 7 and can rotates around axle core 8 by axle core 8, the length of chute 7 can limit the range of activity of connecting rod 6, the described length that can according to the actual needs chute 7 be set to needs, facilitates doctor to operate fast.Because connecting rod 6 can change with the angle of cutter head 52 in rotary course, thus connecting rod 6 with cutter head 52 for pivotable is connected, can make cutter head 52 to coordinate cutting with tool rest 51.
The inside of described tong arm 2 is provided with the first cavity, described draught line 3 is positioned at the first cavity of tong arm 2 inside, described finger ring handle 1 is connected with the first end of described draught line 3, in the time that finger ring handle 1 closes up, draught line 3 is pulled to the direction of finger ring handle 1, and the second end that affects connecting rod 6 make it along chute 7 to binding clip 5 second end rotate, now the first end of connecting rod 6 promote cutter head 52 move to tool rest 51, complete cutting.Described tong arm 2 inside are also provided with the second cavity, and described stick 9 is positioned at the second cavity, and the first end of described stick 9 is connected with the second end pivotable of binding clip 5, and the second end of described stick 9 is connected with the stick control device 10 that is arranged on tong arm 2 first ends.
Wherein, described stick control device 10 is provided with 3-5 gear, described stick control device 10 is slide block, be that slide block one side is provided with 3-5 gear confinement block, in the time that slide block slides on tong arm 2, can be subject to the restriction of gear confinement block, be to be mainly convenient to doctor fast and accurately binding clip 5 to be adjusted to suitable angle.This structure is comparatively general in life, just repeats no more at this.Described slide block is fixedly connected with the second end of stick 9, and when slide block is slided to binding clip 5 directions, stick 9 promotes binding clip 5, and binding clip 5 is bent downwards, reaches the object of turning; Otherwise when slide block is slided to the direction of finger ring handle 1, stick 9 pulls binding clip 5, and binding clip 5 is upwards bent, and can make binding clip 5 and tong arm 2 point-blank, again pulls and can make binding clip 5 upwards continue bending, reaches the object being bent upwards.The design is convenient to, by the tract of human body bending, be convenient to doctor and steal biopsy for biopsy forceps.
Wherein, described cutter head 52 is that cross section is polygon or circular open tubular column, on described tool rest 51, the face relative with cutter head 52 is the curved surface caving inward, rib on described cutter head 52 end face relative with tool rest 51 is the sharp edge of a knife, it is in order to steal after biopsy that cutter head 52 is designed to the curved surface that open tubular column and tool rest 51 be designed to depression, organize and directly fall into hollow cutter head 52, be convenient to biopsy to take out in human body.The face that described tool rest 51 is relative with cutter head 52 also can be plane, and this utility model does not do this restriction to tool rest 51.
Wherein, biopsy forceps of the present utility model to damage and can make biopsy forceps enter smoothly body cavities patient body in order to reduce, so hereby the end face of the first end of binding clip 5 is designed to the cambered surface of rounding off or the Cross-section Design of sphere and tong arm 2 and tool rest 51 for circular or oval.
Wherein, laparoscopically apparatus is the straight tube turnover by being about 7cm left and right, and the diameter maximum of this straight tube is no more than 1.2cm, so the long diameter of tong arm 2 described in the utility model is preferably 0.5cm, the long diameter of described tool rest 51 is preferably 0.5cm.
