Technical field
The present invention relates to a kind of interchangeable cartridge device for surgical stapling device is applying line on a kind of intraluminal tissue
Property row, and cut the surgical stapling device corollary apparatus of tissue between this linear rows stiching instrument, for replaceable nail bin simultaneously
Device.
Background technology
Abdominal cavity formula and/or interior peep in operation process, operation process is narrow by the little otch of patient or insertion wound
Narrow sleeve pipe is carried out.During traditional or open, doctor directly contacts operative site.The patient's wound being reduced due to it
Wound, shortens patient's convalescent period and significantly reduces overall cost, and formula operating-table opposing open operation in abdominal cavity has advantage.In order to coordinate
Inner peeping type and the real needs of abdominal cavity formula, inner peeping type robotic suturing device has been developed that and enables the clinician to contact with comparalive ease Surgery
Position.Typically, these suture instrumentses include being supported on approach robotic suturing device end can be hinged tool component.This tool component
Can be enabled the surgeon to manipulate operation device in limited space by selectively manipulation.These instruments are given and interior peeped operation and provide
Significantly medical benefit.Nevertheless, it is desirable to reduce and manufacture in cost improve to some extent in complexity.
At present Endo-GIA is that open Endo-GIA apparatus volume ratio is larger, and surgical patient otch ratio is larger,
Patient is recovered with pessimistic time long, increase patient suffering, current Endo-GIA osculating head is non-exchange, same apparatus
It is not practicable for different osculating heads and changes use, it is non-rotatable, using not convenient that osculating head is fixed on anastomat head.
Nail bin and nail supporting base currently used for surgical stapling device connect together, and must connect when changing nail bin in operation process
Change together with nail supporting base, increase operating theater instruments cost, increase corrective surgery financial burden.
Content of the invention
The present invention seeks to for above-mentioned weak point provide a kind of for surgical stapling device can more cartridge device, permissible
Reduce operating theater instruments cost, mitigate corrective surgery financial burden.
A kind of interchangeable cartridge device for surgical stapling device takes technical scheme below to realize:
