Abstract
The utility model relates to an accessory for a biopsy instrument, in particular to a horizontal pipe combined structure for the biopsy instrument. The horizontal pipe combined structure comprises a first rod, a second rod, a third rod, a fourth rod and a fifth rod, wherein a connection hole is formed on the head portion of the first rod, the first rod penetrates into the second rod, the second rod penetrates into the third rod, and the third rod penetrates into the fourth rod. The fifth rod is composed of a connection portion, a transition portion and a penetrating portion sequentially from front to back, and the connection portion penetrates onto the tail portion of the fourth rod and is fixedly connected with the fourth rod. Limit bosses are formed on the front portions of the second rod, the third rod and the fourth rod respectively, threaded holes are arranged on the bosses, and set screws are connected into the threaded holes in a threaded mode. The horizontal pipe combined structure has a large extensible range, is ensured not to extend out of the extensible maximum stroke during unfolding and folding due to the limit devices, is modularized, can be replaced easily and can be matched with other parts of the biopsy instrument simply.
Description
Technical field
This utility model relates to a kind of biopsy instrument accessory, especially a kind of biopsy instrument transverse tube combinative structure.
Background technology
At present biopsy instrument is little with the scalable scope of transverse tube, in addition transverse tube when drawing in if too firmly can cause the end of slide bar can be overlapping with the end of loop bar, inconvenience when needs launch it; If the pulling slide bar too firmly can make slide bar surpass its range to come off from loop bar, existing biopsy instrument is not that modular replacing is inconvenient with transverse tube in addition upon deployment.
The utility model content
This utility model is intended to address the above problem, and a kind of biopsy instrument transverse tube combinative structure is provided, and its scalable scope is big, have stopping means to guarantee that it does not exceed telescopic range when launching and draw in, and its technical scheme that adopts is as follows:
A kind of biopsy instrument transverse tube combinative structure, comprise first rod member, second rod member, the 3rd rod member, the 4th rod member and the 5th rod member, the described first rod member head has the axis connecting hole vertical with the first rod member length direction, described first rod member slidably is threaded onto in second rod member, described second rod member slidably is threaded onto in the 3rd rod member, described the 3rd rod member slidably is threaded onto in the 4th rod member, described first rod member, second rod member, the 3rd rod member and the 4th rod member are cuboid, and cross section is square; Described the 5th rod member is that foursquare connecting portion, cross section are that foursquare transition part and cross section are that the circular portion of installing forms by the cross section from A-P successively, described connecting portion is threaded onto the afterbody of the 4th rod member and affixed with it, the front portion of described second rod member, the 3rd rod member and the 4th rod member all is formed with positive stop lug boss, offer screwed hole on the described boss, holding screw has been threaded in the described screwed hole.
On the technique scheme basis, described second rod member is provided with size scale.
On the technique scheme basis, the afterbody of described first rod member, second rod member and the 3rd rod member is equipped with the anticreep nail, all offers the guide groove that slides for the anticreep nail on described second rod member, the 3rd rod member and the 4th rod member.
The utlity model has following advantage: scalable scope is big, have stopping means to guarantee that it does not exceed telescopic range when launching and draw in, and modularity is easily changed and the other parts of biopsy instrument cooperate simple.
