Abstract
Disclosed is a surgical round tube type stapler. A safety bolt is added between a trigger handle and the main body of the stapler. A diameter-variational segment is disposed on a screw. Block hooks are disposed at the inner sides of the two pins of the safety bolt and distance between the two pins and the block hooks is arranged reasonably so that the stapler has both self-insurance function and second trigger prevention function. Before the stapler is used, the safety bolt pushes against the screw so that the stapler with self-insurance function can't be triggered; when the stapler is used, the safety bolt can open automatically after reaching a trigger position and doctors can do operations conveniently; after trigger is completed, the handle is released, and the safety bolt blocks the screw so that the handle can't reset and the stapler is prevented from being triggered for the second time. The disclosed stapler is provided with a simple and practical structure, a small number of parts, easy assembly, convenience for using, and high security.
Description
Technical field
This utility model relates to Binding Instrument, especially the tubular type binding instrument that surgical operation uses, and is in particular a kind of tubular type binding instrument that is provided with anti-secondary firing lock, belongs to technical field of medical instruments.
Background technology
Binding device for surgery is a kind of medical apparatus and instruments that often uses when physiological tissues such as intestinal are carried out surgical operation, and the difference of this instrument performance plays crucial effects for the whole surgery effect.For preventing the mistake percussion, generally be provided with safety on the Binding Instrument.In the prior art, the mode of operation of safety mostly is greatly manually above the tubular type binding instrument, and the doctor just opens insurance, implements the percussion bookbinding when performing an operation to the patient after every preparation is finished.The actual use finds that there is following defective in this safety: if the doctors experience deficiency, the surgical binding operation also can be opened and implement to safety when not in place in the bookbinding gap, causes surgical effect not good; Perhaps, if forget the insurance of closing when changing the outfit the Binding Instrument head assembly, careless slightlyly will press the percussion spanner, binding needle will hit from the instrument head assembly, causes operative failure.And the doctor who has causes tissue broken by folder for preventing that percussion may not pulled the trigger fully once more.
Chinese patent 98121969 adopts a spring to make the stop button self-return prevent to pull the trigger again, and its shortcoming is: spring is positioned at originally external, and the danger that clips to tissue is arranged.Just because of this, according to the knowledge of the applicant, the actual at present Binding Instrument that uses all is not provided with anti-secondary percussion lock.
Summary of the invention
The purpose of this utility model is exactly in order to solve the above-mentioned problems in the prior art, and a kind of tubular type binding instrument that is provided with anti-secondary firing lock is provided, and makes operation more safe and reliable.
The purpose of this utility model is achieved through the following technical solutions:
The tubular type binding instrument, comprise Binding Instrument body, crimp head, firing lock and driving regulating mechanism, the outermost layer of Binding Instrument body is a shell, firing lock comprises handle, ejector pin bar and pushing slice of nail, driving regulating mechanism comprises adjusting knob and screw mandrel, it is characterized in that: this Binding Instrument also is provided with lock, lock one end is connected on the handle, the other end is fluted, the both sides of groove are two feet of lock, and two feet are against the screw mandrel outer surface, and the inboard of two feet is provided with grab, and there is one section reducer in screw mandrel.
The purpose of this utility model can also come further to realize by the following technical programs:
Above-mentioned tubular type binding instrument, wherein, the reducer of described screw mandrel is thin footpath, a place groove, the diameter of thin diameter section is less than the spacing of two feet of described lock and greater than the beeline between the described grab in the groove.
Perhaps, above-mentioned tubular type binding instrument, wherein, there is place's boss in described screw mandrel, and the diameter that its small diameter part divides is less than the spacing of two feet of described lock and greater than the beeline between the described grab; And the middle part of described lock is provided with convex shoulder, is provided with ear above the handle of Binding Instrument and climbs, and is provided with back-moving spring between handle and the lock.
This utility model is set up lock between the percussion handle of tubular Binding Instrument and Binding Instrument body, one section reducer is set on screw mandrel, by inboard grab is set at two feet of lock, and rationally mate the distance between two feet and the grab, make this instrument have voluntary insurance and the function that prevents the secondary percussion concurrently: before the use, lock is against on the screw mandrel, and Binding Instrument can not be pulled the trigger, and has the voluntary insurance effect; In the use, but lock can be opened automatically after arriving firing position, and the doctor can undergo surgery more easily; Unclamp handle after percussion is finished, lock blocks screw mandrel, and handle can not be resetted, and can prevent that instrument from being pulled the trigger once more.Compared with prior art, this utility model features simple structure, few, the easy assembling of part, reliability, the safety of use further improve.
