Abstract

The invention relates to surgical anastomotic instrument, in particular to an automatic control contracting anvil conveying device passed through a mouth. The device is provided with a contracting anvil and a controller. The contracting anvil is composed of an anvil top, contracting pieces and an anvil handle. At least contracting pieces are provided, and the anvil top is connected with the anvil handle which is in an open catheter type. A tail end of the anvil handle is connected with a catheter pipe outside, one side of the anvil handle is provided with a control switch hole, and a tail portion of the anvil handle is provided with a ring-shaped stapler locking groove which is used for fixing ring-shaped stapler. The controller is provided with a control spring, a control rod and a control switch, wherein the control spring is arranged at the front end of the control rod which is arranged in the anvil handle to control the contracting of the contracting of the anvil, and the control switch is arranged at a tail end of the control rod. The devices has the advantages that operations of inserting contracting anvils through mouths in operations are relatively simple, the probability of damaging esophagus in operations is greatly reduced, interferences of control guiding wires in an anastomosis process are effectively avoided due to the fact that the anvil handle automatically triggers the control switch on one side of the anvil handle when inserted in the ring-shaped stapler during the anastomosis process.

Description

The oral delivery nail anvil device that automatic control is shunk

Technical field

The present invention relates to a kind of surgical stapling utensil, especially relate to the oral delivery nail anvil device automatically controlling to shrink.

Background technology

Current, the minimally invasive surgery for reconstruction of digestive tract such as esophaguses coincide and often applies oral delivery nail anvil device, and existing oral delivery nail anvil device comprises nail anvil top, nail anvil handle, guiding tube and control seal wire.Although existing 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 of nail anvil consistent with anastomat diameter (being more than or equal to 2.5cm), because oral cavity in art generally has tracheal intubation to stop, therefore in art, per os is inserted the nail anvil that diameter is more than or equal to 2.5cm and is entered esophagus operation 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) what control nail anvil contraction in art is complete by controlling seal wire, operation trouble relatively in art, and brings certain interference in actual anastomosis procedures in art.

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 oral delivery nail anvil device that a kind of automatic control is shunk is provided.

The present invention is provided with collapsible nail anvil and controller, described collapsible nail anvil is made up of nail anvil top, collapsible and nail anvil handle, establish at least 3 for collapsible, nail anvil top is connected with nail anvil handle, nail anvil handle is hollow tubular, the external guiding tube of nail anvil handle end, and nail anvil handle side is provided with gauge tap hole, the afterbody of nail anvil handle is provided with anastomosis ring applicator draw-in groove, and anastomosis ring applicator draw-in groove is used for stationary annular anastomat; Described controller is provided with control spring, control stick and gauge tap, control spring is located at the front end of control stick, control stick is positioned at nail anvil handle, controls the contraction of collapsible nail anvil, gauge tap be located at control stick tail end and through the gauge tap hole being located at nail anvil handle side.

The present invention has following outstanding advantages:

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

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

3) the present invention controls the contraction of collapsible nail anvil by controller, and in the process of coincideing, nail anvil handle triggers the gauge tap of nail anvil handle side automatically in anastomosis ring applicator process inserting, efficiently avoid in anastomosis procedures the interference controlling seal wire.

Detailed description of the invention

See Fig. 1 ~ 6, the embodiment of the present invention is provided with collapsible nail anvil and controller, described collapsible nail anvil is made up of nail anvil top 11, collapsible 12 and nail anvil handle 13, establish 3 for collapsible 12, nail anvil top 11 is connected with nail anvil handle 13, and nail anvil handle 13 is hollow tubular, the external guiding tube of nail anvil handle 13 end, side, nail anvil handle 13 rear end is provided with gauge tap hole 131, and the afterbody of nail anvil handle 13 is provided with anastomosis ring applicator draw-in groove 132, and anastomosis ring applicator draw-in groove 132 is for stationary annular anastomat; Described controller is provided with control spring 31, control stick 32 and gauge tap 33, control spring 31 is located at the front end of control stick 32, control stick 32 is positioned at nail anvil handle 13, control the contraction of collapsible nail anvil, gauge tap 33 be located at control stick 32 tail end and through the gauge tap hole 131 being located at side, nail anvil handle 13 rear end.

Operational approach of the present invention is as follows:

1) per os inserts guiding tube and connected collapsible nail anvil, collapsible nail anvil is delivered to esophageal stump, causes external by guiding tube end from thoracic wall or stomach wall handle hole;

2) 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 nail anvil handle is fixed in knotting;

3) insert anastomosis ring applicator at the handle hole of thoracic wall or stomach wall, inserted by nail anvil handle in the hole clipping at anastomosis ring applicator center, automatically trigger the gauge tap of nail anvil handle side, the collapsible nail anvil expansion making contraction state is umbrella nail anvil.Rotary annular anastomat end-of-pipe control ring, makes nail anvil be contracted to anastomosis ring applicator top and closely be connected with it, excites anastomosis ring applicator, complete identical.And move anastomosis ring applicator and nail anvil.
