Abstract
The utility model discloses electric coagulation forceps with an elastic locating function. The electric coagulation forceps with the elastic locating function comprises forceps tips and forceps rods, and are characterized in that the a precise locating rod is fixed on one side of the front portions of the forceps rods, and the other side of the front portions of the forceps rods is provided with a corresponding groove. A limit spring is arranged on the middle portion of the forceps rods. Two ends of the limit spring are fixed on the forceps rods of two sides through insulation screw caps. The precise locating rod and the limit spring are arranged on the electric coagulation forceps with the elastic locating function, the limit spring can be used for coarse locating, and meanwhile the limit spring meets the requirements of different operating staff of the opening and the open-and-close force of the electric coagulation forceps. The precise locating rod carries out precise location, and the precision of the location can be guaranteed precisely. The structure can not only guarantee the precision in usage, but also achieve the personalized choice to the opening and the open-and-close force of the electric coagulation forceps.
Description
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 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 elasticity positioning function.
To achieve these goals, by the following technical solutions: a kind of electric coagulation forceps with the elasticity positioning function is characterized in that: front portion one side of described tweezer bar is fixed with the precise positioning bar, and opposite side is provided with corresponding groove; The middle part of described tweezer bar is provided with limit spring.
The two ends of described limit spring are fixed on the tweezer bar of both sides by the insulation nut.
In order to solve the different operating personnel degree of tightness of limit spring is required different problems, as further optimization, limit spring can dismounting and change; Can change as required different model, to adapt to electric coagulation forceps needs to aperture and opening and closing dynamics when different occasions are used.
This utility model is provided with precise positioning bar and limit spring at the tweezer body, and limit spring can be used for coarse positioning, by changing the spring of different model, can satisfy the different operating personnel to the aperture of electric coagulation forceps and the demand of opening and closing dynamics simultaneously; The precise positioning bar is fine positioning, the accurate precision that guarantees the location; Such structure is so that the tweezer bar can be subject to elastic force pulling nature after opening closes up, guaranteed the movement locus of tweezer body, simultaneously because the effect of precise positioning bar, the contact of tweezer point can not misplace, precision when effectively having guaranteed to use has also realized the personalization of electric coagulation forceps aperture and opening and closing dynamics is selected simultaneously.

Fig. 4 is the partial enlarged drawing of B among Fig. 2.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described further.
As depicted in figs. 1 and 2, a kind of electric coagulation forceps with the elasticity positioning function comprises tweezer point 1 and tweezer bar 2, tweezer bar 2 rear portions have electrode tip holder 3, the front portion that has plug 4, one side tweezer bars on the electrode tip holder 3 is fixed with precise positioning bar 8, and opposite side tweezer bar is provided with corresponding groove 7.The middle part of tweezer bar is provided with limit spring 6, and limit spring 6 is fixed on the tweezer bar of both sides by insulation nut 5.Limit spring 6 is detachably changed.
During use, 6 pairs of tweezers of limit spring have been realized coarse positioning, and have limited to a certain extent the maximum opening of tweezer bar 2.Simultaneously, according to the different demands of operator to tweezer bar 2 apertures and opening and closing dynamics, can change the limit spring 6 of different model.
Operator are when using described electric coagulation forceps, pinch and press tweezer bar 2, because the elastic force effect of limit spring 6, tweezer bar 2 can be subject to an extruding force, so that staff is when using, the power that the tweezer point is subject to can be not excessive, and the function of a coarse positioning is also arranged simultaneously, after precise positioning bar 8 passed groove 7 in addition, tweezer point 1 could contact.Such structure is so that tweezer bar 2 can be subject to the elastic force pulling after opening, guaranteed the movement locus of tweezer body, simultaneously because the effect of precise positioning bar 8,1 contact of tweezer point can not misplace, precision when effectively having guaranteed to use has also realized the personalization of electric coagulation forceps aperture and opening and closing dynamics is selected simultaneously.
