Abstract

The present invention relates to a one-off linear stiching instrument triggering protecting device which is applied to the one-off linear stiching instrument and is taken as an inosculation triggering protecting mechanism. A structure comprises a nail resisting base, a protecting block, a protecting spring sheet or a protecting spring and a protecting cover plate. The nail resisting base is provided with a protecting block installing slot. The protecting block is arranged inside the protecting block installing slot the inside of which is equipped with the protecting spring sheet or the protecting spring. The outer side of the protecting block installing slot is equipped with the protecting cover plate. The protecting block is T-shaped or columnar or L-shaped. The one-off linear stiching instrument triggering protecting device has the advantages of reasonable design and compact structure, can not cause triggering without a nail or triggering by mistake due to the function of the protecting block of resisting a nail pushing board, which is safe and protective and can ensure that the operation is processed normally.

Description

Disposable percussion protecting device of linear suture device

Technical field

What the present invention relates to is a kind of Disposable percussion protecting device of linear suture device, is applicable to the identical percussion of disposable linear suture device do insurance institution.

Background technology

At present, disposable linear suture device firing lock lacks in the safety use and nail percussion or mistake percussion can occur not having and have influence on operation and normally carry out, even can cause operative failure.

Summary of the invention

The present invention seeks to provides a kind of Disposable percussion protecting device of linear suture device at above-mentioned weak point, have relief spring sheet or relief spring, safety block, cover plate, relief spring sheet or relief spring, safety block are contained in respectively in the nail supporting base safety groove and are encapsulated by cover plate, in the use because nail pushing plate is withstood in the safety block effect nail percussion or mistake percussion can not appear not having, security insurance can guarantee to perform the operation and normally carry out.

Disposable percussion protecting device of linear suture device is to take following scheme to realize:

The Disposable percussion protecting device of linear suture device structure comprises nail supporting base, safety block, relief spring sheet or relief spring, insurance cover plate, nail supporting base is provided with the safety block mounting groove, safety block is contained in the safety block mounting groove, relief spring sheet or relief spring are housed in the safety block mounting groove, the insurance cover plate are housed in the safety block mounting groove outside.Safety block can adopt " T " font or cylindrical or " L " shape etc.

Disposable percussion protecting device of linear suture device, during use nail supporting base is contained on one's body the disposable linear suture device device together with the percussion safety, because insurance reed or relief spring effect promotion safety block move upward and block the nail pushing plate end face, nail pushing plate can't be travelled forward, be in no spike attitude this moment.Install the anastomosis cut component of nail when insertion after, pushing slice of nail withstands safety block and insurance reed or relief spring and presses downwards and insurance is in nail percussion state is arranged, can pull the trigger state, when percussion back safety block under spring action automatically ejection withstand nail pushing plate and be in safety position.

Reasonable in design, the compact conformation of Disposable percussion protecting device of linear suture device, have relief spring sheet or relief spring, safety block, cover plate, relief spring sheet or relief spring, safety block are contained in respectively in the nail supporting base safety groove and are encapsulated by cover plate, in the use because nail pushing plate is withstood in the safety block effect nail percussion or mistake percussion can not appear not having, security insurance can guarantee to perform the operation and normally carry out.

The specific embodiment

With reference to accompanyingdrawing 1～6, the Disposable percussion protecting device of linear suture device structure comprisesnail supporting base 1,safety block 2,relief spring sheet 3 or relief spring, insurance cover plate 5,nail supporting base 1 is provided with safetyblock mounting groove 4,safety block 2 is contained in the safetyblock mounting groove 4,relief spring sheet 3 or relief spring are housed in the safetyblock mounting groove 4, insurance cover plate 5 is housed in safetyblock mounting groove 4outsides.Safety block 2 can adopt " T " font or cylindrical or " L " shape etc.

With reference to accompanyingdrawing 5,6, Disposable percussion protecting device of linear suture device, during usenail supporting base 1 is contained on one's body the disposable linear suture device device together with the percussion safety, becauseinsurance reed 3 or relief spring effectpromotion safety block 2 move upward and blocknail pushing plate 6 end faces,nail pushing plate 6 can't be travelled forward, be in no spike attitude (referring to accompanying drawing 5) this moment.Install the anastomosis cutcomponent 7 of nail when insertion after, pushing slice ofnail 8 withstandssafety block 2 andinsurance reed 3 or relief spring and presses downwards and insurance is in nail percussion state is arranged, can pull the trigger state (referring to accompanying drawing 6), withstandnail pushing plate 6 when the automatic ejection underinsurance reed 3 or relief spring effect ofsafety block 2 after the percussion and be in safety position (referring to accompanying drawing 5).
