Abstract

An adjustable-precision surgical forceps better solves the problem that precision of an existing forceps cannot be adjusted, and comprises clamping rods and clamping parts, wherein the end of each hollow clamping rod is open, one end of each clamping part is disposed in an opening of a hollow cavity of the corresponding clamping rod, a push-pull rod is disposed in the hollow cavity of each clamping rod, one end of each push-pull rod is fixedly connected with one end of the corresponding clamping part, the other end of each push-pull rod is fixedly connected with a push-pull block, the rear end of each push-pull block is fixedly connected with the front end of a connecting rod, and the rear end of each connecting rod is disposed outside the hollow cavity of the hollow cavity of the corresponding clamping rod. The length of the whole forceps can be adjusted conveniently so as to adjust precision of the forceps, a doctor can conveniently adjust the length of the whole forceps according to the size of an article to be clamped during a surgery, and thereby the forceps is convenient to use. Further, the adjustable-precision surgical forceps is simple in structure and easy in manufacture.

Description

Son is taken the photograph in a kind of operation of adjustable accuracy

Technical field:

This utility model relates to a kind of son of taking the photograph.

Background technology:

The present son of taking the photograph does not have the function of adjusting precision, can not be according to waiting that specifically pressing from both sides the article size adjusts the precision of taking the photograph son, the phenomenon that son can not press from both sides article therefore often occurs taking the photograph when people use.Often use the medical son of taking the photograph in doctor's operation process, but same, the medical son of taking the photograph can not be adjusted its precision, and operation often needs to press from both sides large piece article sometimes, and need to press from both sides minimum article sometimes, and therefore have now and take the photograph the clamping needs that son can not be fit to different article, limited its use.

The utility model content:

Take the photograph the problem that son can not be adjusted precision at existing, this utility model provides a kind of son of taking the photograph, and can address the above problem preferably.

Described purpose is achieved by the following scheme:

Son is taken the photograph in a kind of operation of adjustable accuracy, comprises clamping bar, and described clamping bar is hollow structure and termination openings, also comprises cramping body, and described cramping body one end places in the opening of clamping bar cavity; In the cavity of described clamping bar push-pull bar is set, push-pull bar one end is fixedlyed connected with cramping body one end; The other end of described push-pull bar is fixedlyed connected with the push-and-pull piece, fixedlys connected with the connecting rod front end in push-and-pull piece rear end, and described rod rear end places among the clamping bar outside the cavity.

With the clamping bar inwall of push-and-pull piece opposite position on vertical chute is set, the push-and-pull block edge places in the described chute.

The fixedly connected handle of described rod rear end.

The mode of fixedlying connected between described push-pull bar and cramping body is, described cramping body is fixedlyed connected with contiguous block one end, and described push-pull bar is fixedlyed connected with the contiguous block other end.

The external diameter of described contiguous block and the internal diameter of cavity adapt, with the clamping bar inwall of contiguous block opposite position on vertical chute is set, the contiguous block edge places in the chute.

This utility model will be taken the photograph the clamping bar of son and be arranged to the cavity structure, deploy within it in push-pull bar, promotion or pulling by operating grip may command push-pull bar, the cramping body that places the clamping bar outer end is stretched out or indentation, thereby the convenient entire length of taking the photograph son of adjusting, and then having adjusted the precision of taking the photograph son, the doctor can take the photograph sub length according to treating that the holding articles size is adjusted in operation process, thereby has made things convenient for use.Advantage simple in structure, that be easy to make that this utility model also has.

The specific embodiment:

Elaborate this utility model preferred embodiment below in conjunction with accompanying drawing.

Son is taken the photograph in a kind of operation of adjustable accuracy, comprises clamping bar 3, and described clamping bar 3 is hollow structure and termination openings, also comprises cramping body 1, and described cramping body 1 one ends place in the opening of clamping bar 3 cavities; Push-pull bar 4 is set in the cavity of described clamping bar 3, and push-pull bar 4 one ends are fixedlyed connected with cramping body 1 one ends; The other end of described push-pull bar 4 is fixedlyed connected with push-and-pull piece 5, fixedlys connected with connecting rod 6 front ends in push-and-pull piece 5 rear ends, and described connecting rod 6 rear ends place outside the cavity of clamping bar 3.

With clamping bar 3 inwalls of push-and-pull piece 5 opposite positions on vertical No. two chutes 9 are set, the edge of push-and-pull piece 5 places in described No. two chutes 9 and can be along its longitudinal sliding motion.

The fixedly connected handle 7 in described connecting rod 6 rear ends.

1 mode of fixedlying connected of described push-pull bar 4 and cramping body is, described cramping body 1 is fixedlyed connected with contiguous block 2 one ends, and described push-pull bar 4 is fixedlyed connected with the other end of contiguous block 2.

The internal diameter of the cavity of the external diameter of described contiguous block 2 and clamping bar 3 adapts, with the inwall of the clamping bar 3 of contiguous block 2 opposite positions on a vertical chute 8 is set, the edge of contiguous block 2 places in chute 8 and can be along its longitudinal sliding motion.

Present embodiment is the protection domain that the exemplary illustration of this patent is not limited it; those skilled in the art can also carry out the part to it and change; the short of spirit that exceeds this patent all is considered as the replacement that is equal to this patent, all within the protection domain of this patent.
