Description

Double-pole electric coagulation forceps

Technical field

This utility model relates to a kind of hemostasis instrument, especially a kind of double-pole electric coagulation forceps that is applicable to surgical operation therapy.

Background technology

Electricity coagulates as a kind of mode of stopping blooding efficiently, reliably, is widely used in the surgical operation.Electricity divides face to coagulate with fixed attention and point coagulates two kinds, and monopolar electrocoagulation instrument of the prior art belongs to face with fixed attention, when coagulate blood vessels, large-area condensing may occur, and is too big to the position of burning of tissue; And bipolar coagulation instrument of the prior art, a kind of manual mode bipolar coagulation forceps is disclosed as Chinese patent 94242411.5, this electric coagulation forceps is made up of tweezer body, microswitch and socket, interconnection by lead, and microswitch is arranged in the tweezer body, it condenses to tissue by upper and lower tweezer sheet, but since the tweezer sheet more greatly, shorter, underaction during operation, therefore be not suitable for Wicresoft's wound or the wound that gos deep into organization internal are stopped blooding, can't in microsurgery and cerebral surgery operation, use; And it can't be dismantled, and is not easy to clean.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of reasonable in design, flexible and convenient operation, be applicable to microsurgery and cerebral surgery operation, dismountable double-pole electric coagulation forceps.

The technical scheme in the invention for solving the above technical problem is: this double-pole electric coagulation forceps comprises upper and lower binding clip and the lead that links to each other with binding clip, its construction features is also to be provided with inner core, outer tube and spring handle mechanism, described binding clip and lead are positioned at in-core, spring handle mechanism includes spring handle, guide rod and forward and backward handle set, outer tube is fixedlyed connected with the front hand grip seat, inner core is positioned at outer tube and spring handle mechanism, and fixes with spring handle mechanism; Fixedly connected with forward and backward handle set respectively in the two ends of spring handle, an end of guide rod and front hand grip seat flexibly connect, and its other end is fixedlyed connected with the back handle seat.

Inner core described in the utility model is fixed in the back handle seat of spring handle mechanism by spring catch.

This utility model compared with prior art has following beneficial effect: the point that 1, belongs in electric the coagulating coagulates, and is applicable to the hemostasis of little hemostasis point, can avoid unnecessary condensing, to reduce patient's misery; 2, adopt binding clip and outer tube structure, binding clip is less, and outer tube is longer, can be used for the hemostasis of Wicresoft's wound and organization internal wound, therefore is applicable to microsurgery and cerebral surgery operation; 3, spring handle mechanism has adopted guide-tube structure, and the front hand grip seat can move along conduit, therefore has polarization preferably; 4, inner core can take apart from outer tube and spring handle structure, and it is convenient to clean.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in further detail.

Referring to Fig. 1, present embodiment is made up of outer tube 4, inner core I, the II of spring handle mechanism.The II of spring handle mechanism includes front hand grip seat 9, spring handle 21 and back handle seat 12, outer tube 4 is fixed in the outer base 8, outer base 8 is fixedlyed connected with front hand grip seat 9, one end of spring handle 21 is fixed on the outer base 8 by front hand grip hold-down screw 10, and front hand grip screw 10 is threaded with outer base 8, and the other end of spring handle 21 is fixed on the back handle seat 12 by back handle hold-down screw 11; Inner core I places in outer tube 4 and the II of spring handle mechanism, and it is fixing by spring catch III and back handle seat 12, spring catch III comprises bayonet socket 19, spring 20, dismounting handle 14 and dismounting handle holder 15, inner core I is positioned at bayonet socket 19, bayonet socket 19 links to each other with dismounting handle 14, dismounting handle 14 is connected with dismounting handle holder 15 on being fixed on back handle seat 12, and spring 20 is pressed in the back handle seat 12 by dismounting handle holder 15, dismounting handle 14 and bayonet socket 19; The head of outer tube 4 is provided with insulation 2.

Referring to Fig. 2, also be provided with guide rod 22 and guide rod pipe 23 between pro-handle set 9 and the back handle seat 12, guide rod pipe 23 is positioned at front hand grip seat 9, and an end of guide rod 22 is positioned at guide rod pipe 23, its other end and back handle seat 12 fix, and guide rod 22 can move in guide rod pipe 23.

Referring to Fig. 3, inner core I includes upper grip head 1-1 and lower pliers head 1-2, interior pipe 6, lead 7-1 and lead 7-2, dielectric isolation layer 5 before one end of interior pipe 6 is provided with, its other end links to each other with back dielectric isolation layer 16 by connecting rod 13, back dielectric isolation layer 16 is provided with plug 17 and electric mortiser sheet 18, upper grip head 1-1 and lower pliers head 1-2, lead 7-1 and lead 7-2 are positioned at pipe, the close head place of upper grip head 1-1 and lower pliers head 1-2 is enclosed with insulated sleeve 3, be used for upper grip head 1-1 and lower pliers head 1-2 insulation are isolated, the end of lead 7-1 and lead 7-2 links to each other with lower pliers head 1-2 with upper grip head 1-1 respectively, and its other end links to each other with plug 17 with electric mortiser sheet 18 respectively; By preceding dielectric isolation layer 5 upper grip head 1-1 and lower pliers head 1-2 are separated, thereby make upper grip head 1-1 and lower pliers head 1-2 form two electrodes, electric mortiser sheet 18 and plug 17 are separated by back dielectric isolation layer 16, relatively independent to guarantee two circuits.

By clutching or pull-off spring handle 21, front hand grip seat 9 can drive outer tube 4 and move forward and backward along guide rod 22, therefore has polarization preferably, and along with moving forward and backward of outer tube 4, upper grip head 1-1 and lower pliers head 1-2 also open thereupon or be closed.

When needing dismounting or inner core I being installed, press dismounting handle 14, bayonet socket 19 compresses spring 20 thereupon, and inner core I can extract or insert in outer tube 4 and the II of spring handle mechanism, so that clean.Certainly, except that the spring catch fixed form, inner core I also can be fixed in the back handle seat 12 of the II of spring handle mechanism by alternate manner.

During use, electric mortiser sheet 18 is linked to each other with the positive and negative electrode of power supply respectively with plug 17, just can condense the required position of condensing by spring handle 21 switching upper grip head 1-1 and lower pliers head 1-2.Because binding clip of the present utility model is less, belong to again a little and coagulate, therefore can stop blooding to Wicresoft's wound, can not cause large tracts of land to condense; And its outer tube is longer, therefore can go deep into organization internal and stop blooding.
