Detailed description of the invention
Core of the present invention is to provide the safeties of line cutting stitching instrument under the mirror of a kind of chamber, and under this chamber mirror, the utilization rate of the suturing assembly of line cutting stitching instrument is higher.Another core of the present invention is to provide and a kind ofly comprises line cutting stitching instrument under the chamber mirror of above-mentioned safeties.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1-Fig. 9, in a kind of detailed description of the invention, the safeties of line cutting stitching instrument under the chamber mirror that the embodiment of the present invention provides, comprise fixed handle 1, flexible handle 2, safe sliding block 11, relief spring 12 and handle spring 22, safe sliding block 11 is installed on fixed handle 1, relief spring 12 is connected with safe sliding block 11, handle spring 22 is installed on flexible handle 2 and one end and can offsets with the top of safe sliding block 11, flexible handle 2 is provided with block piece 21, safe sliding block 11 is provided with safety button 13.
The original state of line cutting stitching instrument under the mirror of chamber, block piece 21 and handle spring 22 lay respectively at the both sides of safe sliding block 11, safe sliding block 11 offsets with the front end of block piece 21, flexible handle 2 cannot be closed, stir safety button 13, safe sliding block 11 is moved downward, handle spring 22 rotates under self-acting, one end of handle spring 22 and the top of safe sliding block 11 offset, thus block safe sliding block 11, now, flexible handle 2 is rotatable, hold flexible handle 2, handle spring 22 rotates thus departs from safe sliding block 11, handle spring 22 and safe sliding block 11 depart from moment, lower surface and the safe sliding block 11 of block piece 21 offset, safe sliding block 11 can not be moved up, flexible handle 2 can be rotated further on earth, under the mirror of chamber, line cutting stitching instrument completes percussion.Unclamp flexible handle 2, flexible handle 2 resilience under the effect of handle spring 22, after safe sliding block 11 and the block piece 21 of flexible handle 2 depart from, safe sliding 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 safe sliding block 11, thus be returned to original state.Line cutting stitching instrument under the chamber mirror that the embodiment of the present invention provides, owing to being provided with safeties, staff is in operation, need to open safety button 13 and just can use apparatus, and automatically reset after being used to complete, the mistakenly hit avoiding suturing assembly is sent out, and improves the utilization rate of the suturing assembly of line cutting stitching instrument under the mirror of chamber.Above-mentioned block piece can be cylindrical, and above-mentioned block piece also can be square in addition.
In addition, the block piece 21 of safeties is arc block piece.Flexible handle 2 line cutting stitching instrument under the mirror of chamber does circular motion, and arc block piece can ensure with safe sliding block 11 tangent, and ensure that the stability under loading of safe sliding block 11, and under making chamber mirror, line cutting stitching instrument is 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 is arranged can make the contact area of the bottom surface of arc block piece and safe sliding block 11 less, reduces the wearing and tearing of arc block piece, extends the life-span of arc block piece.
Further, safe sliding block 11 is provided with handle spring draw-in groove 112.Handle spring draw-in groove 112 can ensure handle spring 22 with keep stable during safe sliding block 11 relative motion, avoid handle spring 22 side direction slippage safe sliding block 11.
Further, the bottom of safe sliding block 11 is provided with protruding 111, and protruding 111 can be sheathed in relief spring 12.Relief spring 12 is arranged on protruding 111, and relief spring 12 not easily the phenomenons such as crooked occurs, and the motion of relief spring 12 is more stable.
Preferably, the both sides of safe sliding block 11 are provided with safety button 13.When pulling safety button 13, because safe sliding block 11 both sides are provided with safety button 13, the stress equalization of safe sliding block 11, not fragile safe sliding block 11.
Preferred, the end of handle spring 22 is fillet.After opening safety button 13, one end of handle spring 22 and the top of safe sliding block 11 offset, and then rotate flexible handle 2, handle spring 22 removes the top of safe sliding block 11.When the end of handle spring 22 is fillet, the end of handle spring 22 is more smooth, and handle spring 22 more easily removes safe sliding block 11.
In addition, the top of safe sliding block 11 is provided with inclined-plane 113.The inclined-plane 113 of the top setting of safe sliding block 11, make the apex area of safe sliding block 11 less, under the mirror of chamber, line cutting stitching instrument is when recoil state, and safe sliding block 11 more easily blocks block piece 21.
Line cutting stitching instrument under the chamber mirror that the embodiment of the present invention provides, comprise device body and be installed on device above-mentioned safeties with it, the structure of other parts with reference to prior art, can repeat no more herein.
Above line cutting stitching instrument under the mirror of chamber provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
