Abstract

The utility model discloses electric coagulation forceps with a locating chain device. The electric coagulation forceps with the locating chain device comprises forceps tips and forceps rods, and are characterized in that a first curve surface curving inward is arranged on one side of the front ends of the forceps tips, a corresponding second curve surface curving outward is arranged on one forceps rod of the other side, the two curve surfaces accord with each other precisely, and a locating chain used for connecting the two forceps rods is arranged on the middle portion of the forceps rods. The curve surfaces are arc-shaped curving surfaces or elliptic-arc-shaped curving surfaces, and the inner sides and the outer sides of the curving surfaces are all smooth surfaces. A curve surface locating structure and the locating chain device are arranged on the electric coagulation forceps with the locating chain device, wherein the curve surface locating structure is used for precise locating, and the locating chain is used for coarse locating and limiting the opening degree of the forceps rods. The locating chain device effectively guarantees the movement locus of a forceps body, and meanwhile due to the precise coincidence of the two curve surfaces, malposition can not occur when the forceps tips touch with each other, using precision is effectively guaranteed, and the opening degree of the forceps rods is limited at the same time.

Description

A kind of electric coagulation forceps with the locate chain device

Technical field

This utility model relates to a kind of surgical instruments that makes electric current transmit on-mechanical formula energy to human body by the mode of tissue to be heated.

Background technology

Electric coagulation forceps is modern medicine a kind of surgical instruments commonly used.Existing electric coagulation forceps comprises tweezer point, insulation tweezer bar and electrode tip holder successively, and the tweezer point is generally round and smooth outward appearance, and the plug at electrode tip holder rear portion links to each other with external host by wire.The tweezer point of electric coagulation forceps provides high-frequency electrical energy to lesion tissue, makes the protein dehydration between the tweezer point and solidifies, and reaches the purpose of hemostasis.Because its sphere of action is only limited between two tweezer points, therefore very little, quite safe to degree of injury and the coverage of adjacent tissue.During use, need the continuous opening and closing tweezer of personnel bar, so that the contact of two tweezer points.Because the tweezer bar is longer, the contact of tweezer point often can misplace, and causes to occur the inaccurate problem in location when using.

The utility model content

The purpose of this utility model provides a kind of electric coagulation forceps with the locate chain device.

To achieve these goals, by the following technical solutions: a kind of electric coagulation forceps with the locate chain device, comprise tweezer point and tweezer bar, it is characterized in that: front end one side of described tweezer bar is provided with crooked to the inside first surface, be provided with corresponding laterally the second curved surface of bending on the opposite side tweezer bar, two curved surface precisions are agreed with, and tweezer bar middle part also is provided with and is connected to two locate chains on the tweezer bar.

Described curved surface is circular arc type curved surface or oval arc-shaped curved surface, and the inside and outside both sides of curved surface are smooth surface.

Tweezer bar both sides are fixed in by insulator cap in described locate chain two ends.

This utility model is provided with curved surface location structure and locate chain device at the tweezer body, and its mean camber location structure is used for fine positioning, and locate chain is used for the aperture of coarse positioning and restriction tweezer bar.The locate chain device has effectively guaranteed the movement locus of tweezer body, and the while, the contact of tweezer point can not misplace owing to the precision of two curved surfaces is agreed with, the precision when effectively having guaranteed to use, and the while has also been limited the aperture of tweezer bar.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is described further.

As shown in Figure 1 to Figure 3, a kind of electric coagulation forceps with the locate chain device, comprise tweezer point 1 and tweezer bar 2, tweezer bar 2 rear portions have electrode tip holder 3, have plug 4 on the electrode tip holder 3, and tweezer bar 2 anterior close tweezer points 1 place is provided with the curved surface location structure, wherein, the first surface 7 of one side is to tweezer bar 2 inside bend, and opposite side the second curved surface 8 is crooked laterally, and first surface 7 and the second curved surface 8 must precision agree with.Middle part at tweezer bar 2 also is provided with locate chain 6, and locate chain 6 is fixed on the tweezer bar of both sides by insulator cap 5.

During use, 6 pairs of tweezers of locate chain have been realized coarse positioning, and have limited to a certain extent the maximum opening of tweezer bar 2.The work of fine positioning is then transferred to the curved surface location structure and is realized.

Operator when using described electric coagulation forceps, pinching tweezer bar, the tweezer bar can slowly close up along with the crooked pulling function of locate chain, guide two curved surfaces slowly to press close to, until two curved surface precisions are agreed with the position, this moment, the tweezer point can touch together fully, had realized the accurate location to the tweezer point.Simultaneously, owing to the length that draws high of locate chain is fixed, so also limited the aperture of tweezer bar.

If when pinching tweezer bar, little dislocation has appearred in two tweezer bars, two curved surfaces just can not correctly agree with so.At this moment, because that two curved surfaces all are non-ordinary lights is sliding, and what adopt is the arc-shaped surface structure, and therefore, inner curve can be slided naturally along the path of outer N-Side surf, until the complete precision of two curved surfaces is agreed with the position, reaches the purpose to the accurate location of tweezer point.

Claims
