The specific embodiment
Core of the present invention provides the safety of straight cuts stiching instrument under the mirror of a kind of chamber, and the utilization rate of the suturing assembly of straight cuts stiching instrument is higher under this chamber mirror.Another core of the present invention provides straight cuts stiching instrument under a kind of chamber mirror that comprises above-mentioned safety.
In order to make those skilled in the art understand technical scheme of the present invention better, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1-Fig. 9, in a kind of specific embodiment, the safety of straight cuts stiching instrument under the chamber mirror that the embodiment of the invention provides, comprise fixed handle 1, flexible handle 2, insurance slide block 11, relief spring 12 and handle spring 22, insurance slide block 11 is installed on the fixed handle 1, relief spring 12 is connected with insurance slide block 11, handle spring 22 is installed on the flexible handle 2 and an end can offset with the top of insurance slide block 11, flexible handle 2 is provided with block piece 21, and insurance slide block 11 is provided with safety button 13.
The original state of straight cuts stiching instrument under the mirror of chamber, block piece 21 and handle spring 22 lay respectively at the both sides of insurance slide block 11, insurance slide block 11 offsets with the front end of block piece 21, make the flexible handle 2 can't be closed, stir safety button 13, insurance slide block 11 is moved downward, handle spring 22 rotates under self-acting, one end of handle spring 22 offsets with the top of insurance slide block 11, thereby blocks insurance slide block 11, at this moment, flexible handle 2 is rotatable, hold flexible handle 2, thereby handle spring 22 rotates disengaging insurance slide block 11, handle spring 22 and insurance slide block 11 break away from moment, the lower surface of block piece 21 offsets with insurance slide block 11, insurance slide block 11 can not be moved up, and flexible handle 2 can be rotated further on earth, and the straight cuts stiching instrument is finished percussion under the mirror of chamber.Unclamp flexible handle 2, flexible handle 2 resilience under the effect of handle spring 22, after the block piece 21 of insurance slide block 11 and flexible handle 2 breaks away from, insurance slide block 11 is under the effect of relief spring 12, pop up, make block piece 21 and handle spring 22 lay respectively at the both sides of insurance slide block 11, thereby be returned to original state.Straight cuts stiching instrument under the chamber mirror that the embodiment of the invention provides, owing to be provided with safety, the staff is in operation, safety button 13 need be opened and just apparatus can be used, and automatically reset after being used to complete, avoid the mistake percussion of suturing assembly, improved the utilization rate of the suturing assembly of straight cuts stiching instrument under the mirror of chamber.Above-mentioned block piece can be for cylindrical, and above-mentioned block piece also can be for square in addition.
In addition, the block piece 21 of safety is the arc block piece.Flexible handle 2 straight cuts stiching instrument under the mirror of chamber is done circular motion, and the arc block piece can guarantee with to insure slide block 11 tangent, and has guaranteed the stability under loading of insurance slide block 11, makes under the mirror of chamber the straight cuts stiching instrument more steady in use.
In addition, the bottom surface of arc block piece is provided with groove.The groove that the bottom surface of arc block piece arranges can make the bottom surface of arc block piece less with the contact area of insurance slide block 11, reduces the wearing and tearing of arc block piece, has prolonged the life-span of arc block piece.
Further, insurance slide block 11 is provided with handle spring draw-in groove 112.Handle spring draw-in groove 112 can guarantee that handle spring 22 keeps stable with insurance slide block 11 relative motioies the time, avoided handle spring 22 side direction slippages insurance slide block 11.
Further, the bottom of insurance slide block 11 is provided with projection 111, and projection 111 can be sheathed in the relief spring 12.Relief spring 12 is installed on the projection 111, and relief spring 12 is difficult for phenomenons such as crooked take place, and the motion of relief spring 12 is more stable.
Preferably, the both sides of insurance slide block 11 are provided with safety button 13.When pulling safety button 13, because insurance slide block 11 both sides are provided with safety button 13, the stress equalization of insurance slide block 11, not fragile insurance slide block 11.
Preferred, the end of handle spring 22 is fillet.After opening safety button 13, an end of handle spring 22 offsets with the top of insurance slide block 11, rotates flexible handle 2 then, and handle spring 22 is removed the top of insurance slide block 11.When the end of handle spring 22 was fillet, the end of handle spring 22 was more smooth, the handle spring 22 easier insurance slide blocks 11 of removing.
In addition, the top of insurance slide block 11 is provided with inclined-plane 113.The inclined-plane 113 that the top of insurance slide block 11 arranges makes the apex area of insurance slide block 11 less, and the straight cuts stiching instrument is insured the slide block 11 easier block pieces 21 that block under the mirror of chamber when recoil state.
Straight cuts stiching instrument under the chamber mirror that the embodiment of the invention provides comprises the device body and is installed on device above-mentioned safety on one's body that the structure of other parts can be with reference to prior art, and this paper repeats no more.
More than straight cuts stiching instrument under the mirror of chamber provided by the present invention is described in detail.Used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
