Abstract
The invention discloses a disposable small-bore tubular alimentary canal stapler, comprising a fixed handle, a movable handle, an osculating assembly and a nail butting seat assembly. The nail butting seat assembly comprises a nail butting seat with an integrated structure, a locating shaft and a puncture shaft. The locating shaft is positioned between the rear end of the nail butting seat and the puncture shaft, extends into the osculating assembly and is in a match connection with the osculating assembly, a circlip pipe is snapped and installed into the puncture shaft, and an adjusting screw connected with the circlip pipe is arranged in the fixed handle. The nail butting seat, the locating shaft and the puncture shaft are designed into an integrated structure, the present connection mode between the circlip pipe and the puncture shaft in a gun body is changed into the mode that the circlip pipe is snapped and connected to the puncture shaft, and the circlip pipe, the puncture shaft and the locating shaft form a molding and positioning system of an apparatus. According to the present invention, the minimum osculating bore of the stapler can be 14.2mm, which more accords with the scope of the bore of human body organization after natural expansion, and the stapler is easily introduced into the human body organization. The stapler can effectively prevent organization stain and reduce time for wound healing.
Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of disposable small-bore tubular digestive tract stapler.
Background technology
With regard to tubular digestive tract stapler commonly used at present, what adopt on the structure is built-in jump ring in the nail supporting base assembly, with the puncture axle ways of connecting in the rifle body; The osculating lowest calibre that this structure can realize is 15.5mm; The doctor is difficult to import hepatic duct in operating process, cause tissue to pull easily; Make wound healing time extend, increased patient's sick and wounded misery.
Summary of the invention
The technical problem that the present invention will solve is: overcome the deficiency in the prior art; A kind of disposable small-bore tubular digestive tract stapler is provided; Satisfy the caliber size of tissue natural extension, it is inner more to be prone to import tissue during operation, reduces the generation that tissue is pulled phenomenon.
The technical solution adopted for the present invention to solve the technical problems is: a kind of small-bore tubular digestive tract stapler; Comprise fixed handle, flexible handle, anastomosis cut component and nail supporting base assembly; Be provided with in the fixed handle and be connected with anastomosis cut component and by the straight ejector sleeve of flexible handle control percussion; Be provided with retainer and joint sleeve successively between fixed handle and the anastomosis cut component rear end; Nail supporting base assembly and anastomosis cut component front end are connected, and the external diameter of described anastomosis cut component is 14.0～15.0mm, and the nail supporting base assembly comprises nail supporting base, locating shaft, the puncture axle of integrative-structure and is located at the block that the nail supporting base front end is ellipse arc; Locating shaft is between nail supporting base rear end and puncture axle; Locating shaft puts in the anastomosis cut component and is connected with anastomosis cut component, snaps on the puncture axle jump ring pipe is installed, and is provided with the adjusting screw mandrel that is connected with the jump ring pipe in the fixed handle.
Be the convenient adjusting of regulating screw mandrel, described fixed handle rear end is provided with and regulates the regulating handle that wire rod thread is connected.
Simultaneously between described fixed handle and flexible handle, be provided with stop button.
The invention has the beneficial effects as follows: the present invention is designed to integrative-structure with nail supporting base and locating shaft, puncture axle; With the puncture axle ways of connecting in existing jump ring and the rifle body, become the jump ring pipe clamp and be connected on the puncture axle, with the molding navigation system of locating shaft formation apparatus; The minimum osculating bore that can realize anastomat is 14.2mm; The bore scope that meets tissue natural extension more adds the nail supporting base block that is ellipse arc, imports tissue during operation more easily; Prevent that effectively tissue from pulling, shorten wound healing time.
