Surgical operation is widely used in wound suture, interior tissue stitching and cutting with straight line seaming and cutting device.The surgical operation development has more and more been tended to Minimally Invasive Surgery so far.Broad sense, the operation that can reduce wound all is called Minimally Invasive Surgery, and the Minimally Invasive Surgery of the narrow sense that it is generally acknowledged is meant the operation of under endoscope, carrying out.Operation under the endoscope is general only need open several apertures on patient's health, excision, suture tissue and auxiliary apparatus are stretched in the patient body undergo surgery from aperture.Minimally Invasive Surgery is little to the wound that patient brings, and patient can recover in a short period of time, so Minimally Invasive Surgery more and more receives people's attention.
United States Patent (USP) 7753246 has disclosed a kind of microtrauma type straight line seaming and cutting device, comprises a housing, is provided with a percussion assembly in the housing, and said percussion assembly can promote to be positioned at the nail bin groupware of its front end and sew up and excise.After operation finishes, drive the rollback button that is arranged on the shell near-end said percussion assembly is retracted.In the prior art, on the housing of microtrauma type straight line seaming and cutting device an elongated slot is arranged, said rollback button extend in the housing through elongated slot and is fixedly connected with said percussion assembly.Because the rollback button protrudes in the left and right sides of the housing of microtrauma type straight line seaming and cutting device greatly, so the apparatus packing cost is higher, and relatively waste the storage space; And the rollback button in transportation, collides and the risk of accidental damage is also higher.
The utility model content
The purpose of this utility model: propose a kind of microtrauma type straight line seaming and cutting device with rollback button of the top that is arranged on apparatus.
The purpose of this utility model will be achieved through following technical scheme:
A kind of microtrauma type straight line seaming and cutting device; Comprise: housing; Be arranged at the intravital percussion assembly of shell movably; Be connected in the nail bin groupware that said percussion assembly front end is sewed up and excised, the near-end of said percussion assembly is fixed with a rollback button, and the drive division of said rollback button is arranged on the top of said housing.
Preferably; Be fixed with a U-shaped connecting rod on the said rollback button; Two linking arms of said U-shaped connecting rod insert and are fixed on the said rollback button; The cross bar of said U-shaped connecting rod passes two walls of said housing and is positioned at the intravital percussion assembly of said shell, and said housing is provided with and is used to reserve the elongated slot that said U-shaped connecting rod is advanced.
Preferably, said U-shaped connecting rod is fixedly formed by a L shaped bar and a straight-bar.
Preferably, said hull outside is fixed with a shell, and said shell is covered in said elongated slot at least, and two linking arms of said U-shaped connecting rod pass the gap between said shell and the housing.
Preferably, the Breadth Maximum of the Breadth Maximum of said rollback button and said shell is suitable.
Preferably, be clamping between said housing and the shell.
Preferably; Said rollback button comprise interfix one slide a pedestal and a drive division; The said axial width that slides the axial width of pedestal greater than said drive division, said drive division slides on the pedestal perpendicular to said, and said drive division is respectively 2 arcwall faces along its axial direction.
Preferably, the distally arcwall face of said drive division be smooth and convex surface towards the arcwall face in a distant place, said nearside arcwall face is provided with reinforcement.
The beneficial effect of this utility model is mainly reflected in:
(1) because the rollback button is arranged on the top of apparatus, the institute that has therefore reduced apparatus takes up space, and has saved packing.
(2) reduced owing to the risk that makes the fracture of rollback button is collided in transportation.
(3) avoided the side elongated slot to fall into the defective of foreign body.
(4) simple in structure, easy to assembly, be very suitable for practicality.

The specific embodiment
This utility model has disclosed a kind of microtrauma type straight line seaming and cutting device; As shown in Figure 1; Consistent with prior art, comprising: housing 1 is arranged at the intravital percussion assembly 2 of shell movably; Pivot being used on said housing 1 drives the handle 3 of percussion assembly 2, is connected in the nail bin groupware (not shown) that said percussion assembly 2 front ends are sewed up and excised.
To shown in Figure 4, the near-end of said percussion assembly is fixed with a rollback button 4 in conjunction with Fig. 2, said rollback button 4 comprise interfix one slide a pedestal 42 and a drive division 41, the said axial width that slides the axial width of pedestal 42 greater than said drive division 41.Said drive division 41 slides on the pedestal 42 perpendicular to said, and the drive division 41 of said rollback button 4 is arranged on the top of said housing 1.Said drive division 41 is respectively 2 arcwall faces along its axial direction, is respectively distally arcwall face 43, nearside arcwall face 44.The distally arcwall face 43 of said drive division be smooth and convex surface towards the arcwall face in a distant place, said nearside arcwall face 44 is provided with reinforcement 45.
In this preferred embodiment, said housing 1 outside is fixed with a shell 5, is clamping between said housing 1 and the shell 5.Therefore in this utility model, housing 1 is an inner shell in fact.
Be fixed with a U-shaped connecting rod on the said rollback button 4; Two linking arms 6 of said U-shaped connecting rod insert and are fixed on the said rollback button 4; The cross bar 7 of said U-shaped connecting rod passes two walls 11 of said housing 1 and is positioned at the intravital percussion assembly 2 of said shell, and said housing axially is provided with along it and is used to reserve the elongated slot 8 that said U-shaped connecting rod is advanced.For the convenience of making, said U-shaped connecting rod is fixedly formed by a L shaped bar and a straight-bar, that is: said straight-bar is a linking arm 6, and said L shaped bar is a linking arm 6 and cross bar 7 be combined intos.The connected mode of said L shaped bar and straight-bar has a lot, and for example screw thread is fixing etc.
