Description
Technical field
The present invention relates to a kind of surgical stapling utensil, especially relate to a kind of collapsible and telescopic oral delivery nail anvil device.
Background technology
Current, the microinvasive surgical teatment for digestive tract tumor such as esophagocardial carcinomas often applies oral delivery nail anvil device, and this oral delivery nail anvil device comprises per os nail anvil embedded device and anastomosis ring applicator.Although current oral delivery nail anvil device makes reconstruction of digestive tract minimally invasive surgery coincide become possibility, in process of clinical application, still have following inconvenience:
1) diameter consistent with anastomat diameter (being more than or equal to 2.5cm) of current nail anvil, in art, oral cavity generally has tracheal intubation to stop, thus in art, per os is inserted nail anvil that diameter is more than or equal to 2.5cm and entered esophagus and operate relative difficulty;
2) in art, per os is inserted the nail anvil that diameter is more than or equal to 2.5cm and is entered esophagus, when introitus oesophagi arrives anastomotic position, easily causes Esophageal mucosa injury.
3) because nail anvil length needs to mate with anastomosis ring applicator, the about 5cm of length of nail anvil, because nail anvil is metallic hard material, the process relative difficulty of inserting in art, particularly enters esophagus process through throat bending section particularly difficult;
4) in art, per os is inserted the nail anvil that length is more than or equal to 5cm and is entered esophagus, when introitus oesophagi arrives anastomotic position, easily causes bottleneck throat to damage.
Chinese patent CN1252255 discloses a kind of surgical tubular anastomosing device, realize nail anvil position adjusting mechanism and there is speed regulatory function, indicating mechanism can indicate the clamping degree of nail anvil anastomosis staple after all critical positions of nail barrel movement can indicate again anastomosis staple to be shaped, insurance institution only just allows firing handle to be pulled the trigger when tissue to be anastomosed reaches the scope of the grip thickness of applicable anastomosis procedure, being suitable for especially coincide is positioned at the digestive organ in human body deep or the digestive organ at Microendoscopic coincided with human body, also be suitable for the disposable surgical tubular anastomosing device of production low cost on a large scale on streamline especially.
Chinese patent CN2461494 discloses a kind of surgical tubular anastomosing device, before anastomosis procedure performs and when performing, and rigid attachment between nail anvil and the locating rod of anvil pull rod; After anastomosis procedure completes, nail anvil just can roll rotation, is convenient to roll the nail anvil after rotating and exits from more small-bore anastomotic stoma, to avoid tearing anastomotic stoma.Wherein most of parts are made up of the stamping parts of structure and simple shape, moulding and pipe.Be suitable for the digestive organ that coincide and be positioned at human body deep especially or coincide digestive organ at Microendoscopic, being also suitable for the disposable orthochoanitic of production low cost on a large scale on streamline or curved neck formula surgical tubular anastomosing device especially.
Summary of the invention
The object of the invention is to the above-mentioned shortcoming existed for current oral delivery nail anvil device, the collapsible of a kind of improvement and telescopic oral delivery nail anvil device are provided.
The present invention is provided with collapsible nail anvil, guiding tube and controller, described collapsible nail anvil is provided with nail anvil top, collapsible and nail anvil handle, establish at least 3 for collapsible, nail anvil top is connected with nail anvil handle, and the collapsible back side is respectively equipped with control spring groove and anastomosis ring applicator draw-in groove; Nail anvil handle is hollow tubular, and nail anvil handle is provided with the scalable nail anvil handle of at least 2 joint; Nail anvil handle front end is provided with control spring hole, and nail anvil handle end is connected with guiding tube, and side, nail anvil handle rear end is provided with gauge tap hole; Described controller is provided with control spring, control stick and gauge tap, described control stick is provided with at least 2 joint telescopic rods, control spring is located at the front end of control stick, control stick is positioned at nail anvil handle, control the contraction of collapsible nail anvil, gauge tap be located at control stick tail end and through the gauge tap hole being located at side, nail anvil handle rear end.
The present invention has following outstanding advantages:
1) in art per os insert nail anvil operation relatively simple;
2) because nail anvil can shrink, nail anvil diameter can contract and cause 0.5cm, and in operating process, esophageal injury probability reduces greatly;
3) because nail anvil handle is scalable, nail anvil handle can be reduced to corresponding length as required, enters esophagus in operating process easily via bottleneck throat physiological bending position, and bottleneck throat damage simultaneously reduces greatly.
Operational approach of the present invention is as follows:
1) per os inserts guiding tube and connected nail anvil, nail anvil is delivered to esophageal stump, causes external by guiding tube end from thoracic wall or stomach wall handle hole, and utilizing guiding tube internal control seal wire that the nail anvil of contraction state is expanded is umbrella nail anvil;
2) by guiding tube, nail anvil handle is pulled up to greatest length;
3) cut off guiding tube and nail anvil handle junction, remove guiding tube, esophageal stump is with the capable purse string suture of purse wire and knotting is fixed on nail anvil handle;
4) anastomosis ring applicator is inserted at the handle hole of thoracic wall or stomach wall, nail anvil handle is inserted in the hole clipping at anastomosis ring applicator center, rotary annular anastomat end-of-pipe control ring, make nail anvil be contracted to anastomosis ring applicator top and closely be connected with it, excite anastomosis ring applicator, complete identical.And move anastomosis ring applicator and nail anvil.
