Description

Collapsible and telescopic oral delivery nail anvil device

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, 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, in process of clinical application, still have following inconvenience:

1) the present diameter consistent with the anastomat diameter (more than or equal to 2.5cm) of nail anvil, the oral cavity generally has tracheal intubation to stop in the art, thereby per os is inserted diameter and entered esophagus more than or equal to the nail anvil of 2.5cm and operate relatively difficult in the art;

2) per os is inserted diameter and is entered esophagus more than or equal to the nail anvil of 2.5cm in the art, 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 the art is difficulty relatively, particularly enters particularly difficulty of esophagus process through the throat bending section;

4) per os is inserted length and is entered esophagus more than or equal to the nail anvil of 5cm in the art, 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 only just allows firing handle to be pulled the trigger when waiting to coincide the scope of organizing the grip thickness that reaching is fit to coincide operates, 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, also suits especially to produce on a large scale cheaply disposable surgical tubular anastomosing device on streamline.

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 finished, nail anvil just can roll rotation, and the nail anvil of being convenient to roll after the 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 the Microendoscopic digestive organ that coincide, also suits especially to produce on a large scale cheaply disposable orthochoanitic or curved neck formula surgical tubular anastomosing device on streamline.

Summary of the invention

The object of the invention is to the above-mentioned shortcoming for current oral delivery nail anvil device existence, a kind of improved collapsible and telescopic oral delivery nail anvil device is 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, the nail anvil top links to each other 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 the scalable nail anvil handle of at least 2 joints; Nail anvil handle front end is provided with the control spring hole, and nail anvil handle end links to each other 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 present invention has following outstanding advantages:

1) in the art per os to insert nail anvil operation relatively simple;

2) because nail anvil can shrink, and the nail anvil diameter can contract and cause 0.5cm, the esophageal injury probability reduces greatly in the operating process;

3) because the nail anvil handle is scalable, and the nail anvil handle can be reduced to respective length as required, be easy in the operating process enter esophagus by bottleneck throat physiological bending position, simultaneously bottleneck throat damage reduces greatly.

Operational approach of the present invention is as follows:

1) the per os nail anvil that inserts guiding tube and link to each other is delivered to esophageal stump with nail anvil, the guiding tube end is 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 is 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, the terminal control loop of rotary annular anastomat makes nail anvil be contracted to anastomosis ring applicator top and closely continuous with it, excite anastomosis ring applicator, finish identical.And move anastomosis ring applicator and nail anvil.
