Abstract
This utility model relates to technical field of medical instruments, especially a kind of tubular anastomat of tool safety.A kind of tubular anastomat of tool safety, comprise trocar sheath, fixed handle, be positioned at the nail supporting base assembly of trocar sheath front end and be positioned at the adjusting nut of fixed handle rear end, the actuating device making nail supporting base assembly release, regain by rotating adjusting nut is provided with in described fixed handle, described actuating device comprises the axis of guide be connected with nail supporting base assembly, the screw mandrel be connected with adjusting nut and the plate between the axis of guide and screw mandrel, described adjusting nut has nut cap, is provided with the metal spacing sheet withstanding screw mandrel in described nut cap.This utility model improves on the basis of existing technology, positive stop lug boss on nut cap in prior art is removed, load in nut cap and there is certain thickness metal spacing sheet, the strength being applied to adjusting nut during to prevent from appearing at operation is excessive and cause positive stop lug boss to be pushed up the situation of distortion, ensures result of use.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of tubular anastomat of tool safety.
Background technology
Coincide and refer to that the operation of the hollow tissue sections of separation links.Typically, anastomosis procedure carries out after the operation removing the ill of hollow tissue structure or defective part, thus need the link of the remaining terminal part of organizational structure.Depend on performed specific operation and/or other factors, the end section of described tissue can be linked by tubular anastomat.
Tubular anastomat in use, nail supporting base assembly is made constantly near the end of device body by the adjusting nut that turns clockwise, tissue to be anastomosed in the process is constantly compressed, but it is unfavorable that excessive urging tissue can produce the effect of coincideing again, and therefore needing to increase a spacing gap that makes when tissue is compressed to extreme position can not reduce further.Therefore at adjusting nut back end design nut cap, nut cap is provided with positive stop lug boss, and positive stop lug boss and nut cap are integrated injection moldings, positive stop lug boss is used for withstanding screw mandrel, play spacing effect, if but the strength being applied to adjusting nut during operation is excessive, the positive stop lug boss of plastics by top distortion, can will certainly affect result of use.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of tubular anastomat of tool safety.
This utility model solves the technical scheme that its technical problem adopts: a kind of tubular anastomat of tool safety, comprise trocar sheath, fixed handle, be positioned at the nail supporting base assembly of trocar sheath front end and be positioned at the adjusting nut of trocar sheath rear end, be provided with in described fixed handle and by rotating adjusting nut, nail supporting base assembly released, the actuating device regained, described actuating device comprises the axis of guide be connected with nail supporting base assembly, the screw mandrel be connected with adjusting nut and the plate between the axis of guide and screw mandrel, described adjusting nut has nut cap, the metal spacing sheet withstanding screw mandrel is provided with in described nut cap.
Further, described nail supporting base assembly is provided with the sleeve pipe be enclosed within the axis of guide.
Further, described adjusting nut is provided with the alignment pin be connected with screw mandrel.
Further, one end of described plate is fixedly connected with the axis of guide, and the other end of plate is fixedly connected with screw mandrel.
The axis of guide is fixedly connected with plate and screw mandrel, and nail supporting base assembly is by casing pipe sleeve on the axis of guide, and adjusting nut screws in screw mandrel from rear end, nail supporting base assembly can be driven to move forward and backward by the rotation of adjusting nut.
The beneficial effects of the utility model are: this utility model improves on the basis of existing technology, positive stop lug boss on nut cap in prior art is removed, load in nut cap and there is certain thickness metal spacing sheet, the strength being applied to adjusting nut during to prevent from appearing at operation is excessive and cause positive stop lug boss to be pushed up the situation of distortion, ensures result of use.

Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As shown in figures 1-4, a kind of tubular anastomat of tool safety, comprise trocar sheath 1, fixed handle, be positioned at the nail supporting base assembly 2 of trocar sheath 1 front end and be positioned at the adjusting nut 3 of fixed handle rear end, be provided with in trocar sheath 1 and by rotating adjusting nut 3, nail supporting base assembly 2 released, the actuating device regained, actuating device comprises the axis of guide 4 be connected with nail supporting base assembly, the screw mandrel 5 be connected with adjusting nut 3 and the plate 6 between the axis of guide 4 and screw mandrel 5, nail supporting base assembly 2 is provided with the sleeve pipe 7 be enclosed within the axis of guide 4, one end of plate 6 is fixedly connected with the axis of guide 4, the other end of plate 6 is fixedly connected with screw mandrel 5, adjusting nut 3 has nut cap 9, the metal spacing sheet 10 withstanding screw mandrel 5 is provided with in nut cap 9, adjusting nut 3 is provided with the alignment pin 8 be connected with screw mandrel 5.
As shown in Figure 5; the structural representation of the nut cap of tubular anastomat in prior art; nut cap 8 is provided with positive stop lug boss 11, and positive stop lug boss 11 and nut cap 9 are integrated injection moldings, and positive stop lug boss 11 is used for withstanding screw mandrel 5; because strength during operation is excessive; positive stop lug boss 11 often by top distortion, therefore can carry out change in design to it, as shown in Figure 4; remove positive stop lug boss 11, load in nut cap 9 and there is certain thickness metal spacing sheet 10.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
