Description
Technical field
This utility model relates to a kind of surgical stapling utensil, especially relates to a kind of collapsible and telescopic oral delivery nail anvil device.
Background technology
Current, often use oral delivery nail anvil device for the microinvasive surgical teatment of the digestive tract tumor such as esophagocardial carcinoma, this oral delivery nail anvil device comprises per os nail anvil embedded device and anastomosis ring applicator.Become possibility although current oral delivery nail anvil device coincide the reconstruction of digestive tract minimally invasive surgery, still have following inconvenience in process of clinical application:
1) the present diameter consistent with the anastomat diameter (more than or equal to 2.5cm) of nail anvil, in art, the oral cavity generally has tracheal intubation to stop, thereby in art, per os is inserted diameter and entered esophagus more than or equal to the nail anvil of 2.5cm and operate relatively difficult;
2) in art, per os is inserted diameter and is entered esophagus more than or equal to the nail anvil of 2.5cm, when introitus oesophagi arrives anastomotic position, easily causes Esophageal mucosa injury.
3) need to mate with anastomosis ring applicator because of nail anvil length, the about 5cm of the length of nail anvil, because nail anvil is the metallic hard material, the process of inserting in art is difficulty relatively, particularly enters particularly difficulty of esophagus process through the throat bending section;
4) in art, per os is inserted length and is entered esophagus more than or equal to the nail anvil of 5cm, when introitus oesophagi arrives anastomotic position, easily causes the bottleneck throat damage.
Chinese patent CN1252255 discloses a kind of surgical tubular anastomosing device, realize that the nail anvil position adjusting mechanism has the speed regulatory function, the clamping degree of anastomosis staple after all critical positions that indicating mechanism can indicate nail anvil to move relative to nail barrel can indicate again anastomosis staple to be shaped, insurance institution is only just allowing firing handle to be pulled the trigger when the tissue that coincide reaches the scope of the grip thickness that is fit to identical operation, being suitable for especially coincide is positioned at the digestive organ in human body deep or the digestive organ of Microendoscopic coincided with human body, the suitable especially disposable surgical tubular anastomosing device cheaply of producing on a large scale on streamline also.
Chinese patent CN2461494 discloses a kind of surgical tubular anastomosing device, before the operation that coincide is carried out and during execution, and rigid attachment between the locating rod of nail anvil and anvil pull rod; After the operation that coincide was completed, nail anvil just can roll rotation, and the nail anvil of being convenient to roll after rotation withdraws from from more small-bore anastomotic stoma, to avoid tearing anastomotic stoma.Wherein most of parts are made by stamping parts, moulding and the pipe of structure and simple shape.Being suitable for especially coincide is positioned at the digestive organ in human body deep or at Microendoscopic coincide digestive organ, also suitable especially disposable orthochoanitic or the curved neck formula surgical tubular anastomosing device cheaply produced on a large scale on streamline.
Summary of the invention
The purpose of this utility model is to provide improved a kind of collapsible and telescopic oral delivery nail anvil device for the above-mentioned shortcoming of current oral delivery nail anvil device existence.
This utility model 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 pushes up and is connected with the nail anvil handle, and the collapsible back side is respectively equipped with control spring groove and anastomosis ring applicator draw-in groove; The nail anvil handle is hollow tubular, and the nail anvil handle is provided with at least 2 scalable nail anvil handles of joint; Nail anvil handle front end is provided with the control spring hole, and nail anvil handle end is connected with guiding tube, and nail anvil handle rear end one side is provided with the 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 the nail anvil handle, control the contraction of collapsible nail anvil, gauge tap is located at the tail end of control stick and is passed the gauge tap hole of being located at nail anvil handle rear end one side.
The utlity model has following outstanding advantages:
1) in art per os to insert nail anvil operation relatively simple;
2) because nail anvil can shrink, the nail anvil diameter can contract and cause 0.5cm, and in operating process, the esophageal injury probability reduces greatly;
3) because the nail anvil handle is scalable, the nail anvil handle can be reduced to corresponding length as required, is easy in operating process enter esophagus by bottleneck throat physiological bending position, and bottleneck throat damage simultaneously reduces greatly.
Operational approach of the present utility model is as follows:
1) the per os nail anvil that inserts guiding tube and be connected, deliver to esophageal stump with nail anvil, the guiding tube end caused external from thoracic wall or stomach wall handle hole, utilizes guiding tube internal control seal wire processed that the nail anvil of contraction state is expanded and be the umbrella nail anvil;
2) by guiding tube, the 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 fixed on the nail anvil handle with the capable purse string suture of purse wire and knotting;
4) insert anastomosis ring applicator at the handle hole of thoracic wall or stomach wall, the nail anvil handle is inserted in the hole clipping at anastomosis ring applicator center, rotary annular anastomat end control loop makes nail anvil be contracted to the anastomosis ring applicator top and closely be connected with it, excite anastomosis ring applicator, complete identical.And move anastomosis ring applicator and nail anvil.
