Abstract
The utility model discloses electric coagulation tweezers with a pull-draw type location structure. The electric coagulation tweezers comprise tweezers points and tweezers rods and is characterized in that accurate location rods are fixed on one sides of the front portions of the tweezers rods, and corresponding location holes are arranged on the other sides of the front portions of the tweezers rods. The pull-draw type location structure is positioned in middles of the tweezers rods and comprises a pull-draw barrel arranged on one tweezers rod and a pull-draw rod arranged on the other tweezers rod. A cavity of a reversed convex structure is positioned in the pull-draw barrel, the pull-draw rod is in a T shape, and the head portion of the pull-draw rod is positioned in the cavity and can slide in the cavity. The accurate location rods and the pull-draw type location structure are arranged on a tweezers body, the accurate location rods are used for locating accurately, the pull-draw type locations structure is used for locating coarsely, and the pull-draw type location structure can effectively guarantee motion track of the tweezers body. Simultaneously, due to the action of the accurate location rods, tweezers point contact cannot misplace, using accuracy is effectively guaranteed, and the opening degree of the tweezers rods is limited.
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 drawing and pulling type location structure.
To achieve these goals, by the following technical solutions: a kind of electric coagulation forceps with the drawing and pulling type location structure, comprise tweezer point and tweezer bar, it 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 locating hole;
The middle part of described tweezer bar is provided with the drawing and pulling type location structure; Described drawing and pulling type location structure comprises the pull cylinder that is arranged on the side tweezer bar and the pumping rod that is arranged on the opposite side tweezer bar, has the cavity that is the reversed convex type structure in the described pull cylinder, it is T-shaped that pumping rod is, and the head of pumping rod is positioned at cavity, and can slide in cavity.
Described pumping rod and pull cylinder all are fixed on the tweezer bar by insulator cap.
Power-assisted when locating in order effectively to reduce pull, as further optimization, described pull cylinder inwall and pumping rod surface are shiny surface.
This utility model is provided with precise positioning bar and drawing and pulling type location structure at the tweezer body, and wherein the precise positioning bar is used for fine positioning, and the drawing and pulling type location structure is used for coarse positioning; The drawing and pulling type location structure has effectively guaranteed the movement locus of tweezer body, and the while, the contact of tweezer point can not misplace owing to the effect of precise positioning bar, the precision when effectively having guaranteed to use, and the while has also been limited the aperture of tweezer bar.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
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 the drawing and pulling type location structure 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 locating hole 7.The middle part of tweezer bar is provided with the drawing and pulling type location structure, and the drawing and pulling type location structure includes pull cylinder 9 and pumping rod 6, and pull cylinder 9 and pumping rod 6 all are fixed in tweezer bar both sides by insulator cap 5.
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.Precise positioning bar 8 is then transferred in the work of fine positioning and its corresponding locating hole 7 is finished.
Operator are when using described electric coagulation forceps, and pinching tweezer bar 2 drives the slip of pumping rod 6 in pull cylinder 9, and tweezer bar 2 can close up by natures, so that after precise positioning bar 8 passed locating hole 7, tweezer point 1 could contact.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, and simultaneously because the effect of precise positioning bar 8,1 contact of tweezer point can not misplace, the precision when effectively having guaranteed to use.Simultaneously, because the concave structure of pull cylinder 9 and the T-shaped structure of pumping rod 6, when tweezer bar 2 opened up into to a certain degree, pumping rod 6 can be blocked by the bottom of pull cylinder 9, has realized the restriction of electric coagulation forceps aperture.
Claims (3)
