Description

Bipolar single action electricity coagulates nipper

Technical field

This utility model relates to a kind of nipper, and particularly a kind of bipolar single action electricity coagulates nipper, and it mainly is applicable to laparoscopic surgery, belongs to medical instruments field.

Background technology

In laparoscopic procedures, applied medical apparatus and instruments is a lot, and particularly electricity coagulates series pincers class, and prior art generally has one pole and double-pole electric coagulation forceps, but electric coagulation forceps only is used for electric coagulation hemostasis, does not have other function, has satisfied not ideal surgical effect.

The utility model content

This utility model technical problem to be solved is to overcome existing above-mentioned defective in the prior art, and a kind of existing bipolar coagulation function is provided, the bipolar single action electricity that can carry out people's in-vivo tissue organ separation coagulates nipper.

This utility model addresses the above problem the technical scheme that is adopted: nipper comprises active clamp to this bipolar single action electricity with fixed attention, fixedly clamp, first pull bar, claw beam, rotator, first spring, first steel ball, keeper, second spring, the 3rd spring, first adapter sleeve, second adapter sleeve, runner, positioning seat, electricity coagulate plug, fixed handle, flexible handle, draw-bar seat, second steel ball, second pull bar and clamp seat; It is characterized in that: described active clamp is unidirectional bascule, and at active clamp with fixedly have kidney slot on the clamp.

This utility model compared with prior art has the following advantages and effect: reasonable in design, and active clamp and fixedly have waist type groove on the clamp, easy to use and reliable; Simultaneously, existing bipolar coagulation function can be carried out the separation of people's in-vivo tissue organ again, and function is many, and effect is good.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment this utility model is further described.

Referring to Fig. 1-Fig. 3, this utility model is mainly by active clamp 1, fixedly clamp 3, first pull bar 7, claw beam 8, rotator 10, first spring 11, first steel ball 12, keeper 13, second spring 15, the 3rd spring 16, first adapter sleeve 17, second adapter sleeve 18, runner 19, positioning seat 20, electricity coagulate plug 21, fixed handle 22, flexible handle 23, draw-bar seat 26, second steel ball 28, second pull bar 30, clamp seat 31 and claw beam adapter sleeve 34 and form.

Fixed handle 22 is connected with flexible handle 23 usefulness hinge screws 24, can rotate; Pull rod slot 25 is fixing with flexible handle 23 welding, and it is fixing that electric plug 21 with fixed attention is inserted in fixed handle 22 gummeds; The 3rd spring 16 and second steel ball 28 are installed in second adapter sleeve 18, and it is fixing that second adapter sleeve 18 is inserted in fixed handle 22 gummeds, and the 3rd spring 16 coagulates plug 21 with electricity and is connected; Second spring 15 is installed in first adapter sleeve 17, and it is fixing that first adapter sleeve 17 is inserted in fixed handle 22 gummeds, and second spring 15 coagulates plug 21 with electricity and is connected; First spring 11 and first steel ball 12 are installed in the keeper 13; Rotator 10 has 16 positioning seats 20; Rotator 10 is inserted in keeper 13 usefulness nuts 14 and connects, and can rotate, and first steel ball 12 is identical with positioning seat 20 just; Turning rotator 10 has 16 orientations under positioning seat 20 and 12 effects of first steel ball, keeper 13 is inserted in fixed handle 22 to be tightened fixing.It is fixing that claw beam insulation sleeve 9 is inserted in claw beam 8, and claw beam 8 is fixing with claw beam adapter sleeve 34 gummeds, and it is fixing that runner 19 is inserted in claw beam insulation sleeve 9 gummeds; Runner 19 is inserted in fixed handle 22, and claw beam adapter sleeve 34 is inserted in rotator 10 just to be tightened fixingly, and it is fixing that runner 19 is connected with rotator 10 usefulness pins 33.
