Abstract

The utility model discloses electric coagulation forceps with a locating function. The electric coagulation forceps with the locating function comprises forceps tips and forceps rods, and are characterized in that drawing tubes and drawing rods with tip portions positioned in the cavities of the drawing tubes are fixed on the forceps rods on two sides through insulating caps, the cavities of the drawing tubes are in inverted convex shapes, the drawing rods are T-shaped, and springs are arranged between the tips, inside the drawing tubes, of the drawing rods and the inner walls of the drawing tubes. A drawing type locating structure is arranged on a forceps body, the drawing type locating structure effectively guarantees the movement locus of the forceps body, malposition can not occur when the forceps tips touch with each other, the precision of using can be effectively guaranteed, and meanwhile the opening degree of the forceps rods is limited.

Description

A kind of electric coagulation forceps with positioning function

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 positioning function.

To achieve these goals, by the following technical solutions: a kind of electric coagulation forceps with positioning function, comprise tweezer point and tweezer bar, it is characterized in that: the tweezer bar of described both sides is fixed with the pumping rod that pull cylinder and end are positioned at pull cylinder cavity by insulator cap, cavity in the described pull cylinder is reversed convex type, described pumping rod is T-shaped, pumping rod in the pull cylinder the termination and pull cylinder inwall between be provided with spring.

Described pull cylinder inwall and pumping rod have smooth surface.

This utility model is provided with the drawing and pulling type location structure at the tweezer body, and the drawing and pulling type location structure has effectively guaranteed the movement locus of tweezer body, and the contact of tweezer point can not misplace, the precision when effectively having guaranteed to use, and the while has also been limited the aperture of tweezer bar.

Fig. 2 is the top view of Fig. 1;

Fig. 3 is the partial enlarged drawing of A among Fig. 2.

The specific embodiment

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

Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of electric coagulation forceps with positioning function, comprise tweezer point 1 and tweezer bar 2, tweezer bar 2 rear portions have electrode tip holder 3, has plug 4 on the electrode tip holder 3, the middle part of tweezer bar is provided with the drawing and pulling type location structure, the drawing and pulling type location structure comprises pull cylinder 9 and the pumping rod 6 that is separately positioned on the tweezer bar of both sides, pull cylinder 9 and pumping rod 6 are fixed in tweezer bar both sides by insulator cap 5 respectively, the termination of pumping rod 6 is inverted T-shaped, the cavity of pull cylinder 9 is reversed convex type, prevents that like this pumping rod breaks away from the pull cylinder, also is provided with felt pad 8 in the pull cylinder, has spring 7 between the termination of felt pad 8 and pumping rod 9, can guarantee so the rear compression that is squeezed of tweezer bar, when being positioned at naturalness, self-return.Simultaneously, it is stressed that the existence of spring 7 has also reduced the tweezer bar, prevented the tweezer bar and deformed because repeatedly use.

During use, the drawing and pulling type location structure has been realized coarse positioning to tweezers, and has limited to a certain extent the maximum opening of tweezer bar 2.

Operator are when using described electric coagulation forceps, and pinching tweezer bar 2 drives the slip of pumping rod in the pull cylinder, and tweezer bar 2 can close up by nature, guarantee 1 contact of tweezer point.Such structure is so that after tweezer bar 2 is subject to External Force Acting, guaranteed the roughly movement locus of tweezer body by the drawing and pulling type location structure.Simultaneously, because pull cylinder and pumping rod structure, when tweezer bar 2 opened up into to a certain degree, pumping rod can be blocked by the bottom of pull cylinder, had realized the restriction of electric coagulation forceps aperture.

Claims

1. electric coagulation forceps with positioning function, comprise tweezer point and tweezer bar, it is characterized in that: the tweezer bar of described both sides is fixed with the pumping rod that pull cylinder and end are positioned at pull cylinder cavity by insulator cap, cavity in the described pull cylinder is reversed convex type, described pumping rod is T-shaped, pumping rod in the pull cylinder the termination and pull cylinder inwall between be provided with spring.

2. the electric coagulation forceps with positioning function as claimed in claim 1, it is characterized in that: described pull cylinder inwall and pumping rod have smooth surface.
