Description
Technical field
This utility model belongs to a kind of surgical apparatus, is specifically related to the pulled the trigger state automatic prompting device of a kind of disposable end-end anastomat.
Background technology
Digestive tract end-end anastomat is to be used for esophagus, stomach, and the pipeline broken ends of fractured bone and the broken ends of fractured bone in the surgical operations such as intestinal, lumen organizations such as the pipeline broken ends of fractured bone and cavity side fracture coincide.Referring to Fig. 1, when being used for clinical operation, anastomat device body is inserted from a side pipe chamber, the pocket of this side-to-side anastomosis port is tightened up in anvil pull rod (7), (A) imbeds the opposite side tube chamber with the hat nail anvil, and the pocket of this side-to-side anastomosis end tightened up in hat nail anvil (A) center connecting rod, again with the center connecting rod inserter body opposite side anvil pull rod (7) of hat nail anvil, regulate empennage turn-knob (5), making anvil pull rod (7) drive hat nail anvil (A) retreats, until hat nail anvil (A) near the nail casket (B) of device body head and clamp the pocket shape tissue of both sides, when the tissue thickness that clamps arrives safety percussion interval, depress firing handle (9), the titanium seam nail in the nail casket is released, kiss is sewed up by the lumen organization of both sides connect, release endless knife simultaneously and excise the unnecessary tissue at center, annular suture site, the both sides tube chamber is communicated with, extracts anastomat from body lumen again, operation is finished.
In the aforesaid operations process, have only and draw close tissue thickness that the nail casket (B) of device body head clamps when hat nail anvil (A) and arrive the safety percussion when interval, just can depress firing handle (9); At present the anastomat that uses clinically has is provided with suggestion device, promptly moves to can pull the trigger the zone time when anvil pull rod, demonstrates special sign by the housing form; Also there are operator after asking insurance without exception the empennage knob to be screwed to the end in use, to pull the trigger.In the previous case, whether the medical worker will expend too many energy and come the percussion sign in the focus window to occur, and this is disadvantageous beyond doubt concerning the medical worker under the surgical environments; The tissue that under second kind of situation, no matter is cut, coincide is that the thick Bao Douhui of being is compressed as far as possible, wherein thicker tissue may owing to press too densification cause that blood vessels are obstructed to be influenced healing effect even cause local tissue necrosis.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of surgical anastomat can pull the trigger the state automatic prompting device, this device can enter can pull the trigger the zone time at apparatus, send accurately cue clearly from the trend operator, thereby reduce the energy that operator expend.
The technical scheme that addresses the above problem is (referring to implementing illustration): this utility model is provided with the adjusting screw(rod) (2) that is in transmission connection with anvil pull rod (7) in portion's housing (1) after one's death at device, be enclosed within outside the adjusting screw(rod) to localized empennage turn-knob (5) with housing shaft, shank on it (4) embeds the helicla flute (8) on the adjusting screw(rod) (2) movingly, it is characterized in that: described empennage turn-knob (5) rear end face has the port (5a) that is communicated with the housing inner chamber, adjusting screw(rod) (2) rear portion is provided with the mark body (11) that can reach empennage turn-knob rear end face port (5a) when retreating, be provided with one section concave surface backward (8b) to terminal at helicla flute (8) on the described adjusting screw(rod) near on the back cell wall of terminal point, and forming terrace with edge (8a) to back concave surface starting point place.
Further scheme is; Have on described empennage turn-knob (5) sidewall and can aim at the window (10) that retreats post on adjusting screw(rod) (2) or its mark body.
Operation principle of the present utility model is: when rotating empennage turn-knob (5), shank on it (4) slides along the helicla flute on the adjusting screw(rod) (8), adjusting screw(rod) (2) is advanced or retreat, and drive forward anvil pull rod (7) and nail anvil (A) seesaws, when adjusting screw(rod) retreats to terminal (nail anvil A and nail casket B clamp the both sides tissue), mark body (11) follower head at its rear portion moves to the port (5a) of empennage turn-knob rear end face and locates to maintain an equal level with rear end face, the operator that holding the empennage turn-knob this moment can have been moved to the position by feel perception nail anvil, rotating empennage turn-knob (5) simultaneously, when the shank on it (4) acts on adjusting screw(rod) helicla flute (8) back trough wall surface and drives screw rod and retreat, when shank slides near the helicla flute afterbody, during concave surface (8b) after slipping over terrace with edge (8a) near terminal point to enter helicla flute on the cell wall, shank is stressed to be reduced suddenly, the operator of hand-held empennage turn-knob also can obviously feel " clickly " feel of vibrations, to pulling the trigger state, operator can press safety fastener and pull the trigger identical the alert apparatus.
The window that the further scheme of this utility model is provided with on empennage turn-knob sidewall can make operator see the sign that can pull the trigger the zone by window.
This utility model can enter can pull the trigger the zone time at apparatus, sends multiple accurately cue clearly from the trend operator, thereby reduces the energy that operator expend, and improves the accuracy of operation technique.
