Background technology
Linear cutting anastomat is a kind of medicine equipment being widely used in reconstruction of digestive tract and organs resection operation, its
It is easy to use, good operation effect, but there are problems that during existing linear cutting anastomat use.It is straight in the prior art
The push broach of wire cutting stapler is controlled and moved by push button, and cam is rotatably connected on the handle body of stapler, is set on cam
Hook portion is equipped with, when operating push button to promote push broach, push button reach overcomes the resistance between handle body and cam face with moving cam
Power is rotated so that hook portion release push button, but due to pushing directly on push button in the process by push push broach, therefore easily lead
Cause operator's fault ground to promote push broach too early, and when the relation between apparatus and tissue is not adjusted, promote push broach easily to draw
Play malpractice.To solve the above problems, cam is generally abutted against using linkage, cam rotation is prevented, only in connecting rod
In the case that mechanism departs from cam, cam could be rotated, and could then promote push button, and operational error is avoided to a certain extent,
Ensure that security.The settings button typically outside stapler, connecting rod and cam depart from (such as patent when pressing button
Reported in CN2749460Y), but in surgical procedure, may be not intended to press button, can equally cause a certain degree of mistake
Operation.
Utility model content
To overcome stapler present in prior art to easily cause the defect of maloperation, there is provided a kind of single use is straight
Wire cutting stapler.
In order to solve the above technical problems, the application without the technical scheme for being used for：A kind of single use straight cuts
Stapler, including handle body, push broach, staple cartridge tray and resist-nailed seat, slide on the handle body and are provided with for controlling push broach
Mobile push button, the staple cartridge tray and resist-nailed seat are oppositely arranged on one end of the handle body；Pass through in the handle body
Rotating shaft is provided with cam, and the hook portion being connected with the push button is provided with the cam, and guarantor is additionally provided with the handle body
Dangerous mechanism, the insurance institution includes being rotatably arranged on position-limited wheel on the handle body, the position-limited wheel axially with it is described
Cam is axially vertical, and described position-limited wheel is circumferentially provided with stopper slot along it, is provided with the cam and the stopper slot phase
The gag lever post of matching, sets jagged on described stopper slot, and when gag lever post is located at the indentation, there, the cam being capable of edge
Axis of rotation.
Further, for ease of the rotation of the control position-limited wheel, it is provided with outside described handle body and the limit
The rotating part of position wheel drive connection.
Preferably, for convenience of the relative position for observing, controlling gag lever post and breach on the position-limited wheel, the rotating part
On be provided with the pointer corresponding with the gap position, be provided with outside the handle body relative with the gag lever post position
The mark answered, rotates the rotating part, when the pointer is corresponding with the mark, shows that the gag lever post is located at described lacking
At mouthful.It is now in released state, you can promote push button, cam is rotatable, and otherwise gag lever post is located in stopper slot, and cam is not
Can be along its axial-rotation.
Preferably, for ease of the rotation of rotating part, moving tooth is provided with the rotating part.
Preferably, the lid for the rotating part to be covered is provided with outside described handle body, the lid
It is hinged with the handle body.Can be by cover cap when push button need not be operated, it is to avoid be not intended to stir rotating part, and cause
Termination of insurance status.
Beneficial effect：Simple structure in the application, easy to operate, it is rotary safety to change conventional button formula insurance institution
Mechanism, even if being not intended to touching insurance institution in use will not also open insurance, only in rotary stopper wheel, makes spacing
Insurance can just be opened during bar gap position disposed thereon, substantially increase security, reduce the possibility of maloperation.
