Abstract
The utility model discloses a straight stitching and cutting device comprising a staple anvil and a staple chamber which are arranged oppositely, wherein the staple chamber is arranged in a staple chamber support which is in pivot connection with a closed handle, a limit boss is arranged close to the closed handle on the staple chamber support, and a cushion collar is arranged at the outer part of the limit boss. By arranging an arc-shaped groove, which is in surface contact with the limit boss, at the position of the side edge of the closed handle corresponding to the limit boss and adding the cushion collar at the outer part of the limit boss, the straight stitching and cutting device disclosed by the utility model has the advantages of enhancing the comfort level when the straight stitching and cutting device is used.
Description
Technical field
This utility model relates to a kind of surgical operating instrument, is in particular a kind of Linear seam cutting device, belongs to technical field of medical instruments.
Background technology
Linear seam cutting device is widely used in being used in surgical operation wound suture, interior tissue is sewed up and cutting, typical Linear seam cutting device such as US Patent No. 5129570 announcement, have and sew up and two functions of cutting, when carrying out wound suture, with unnecessary cutting tissue.Such Linear seam cutting device generally comprises upper and lower two clamps, and the closed handle that is used for closed upper and lower clamp, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, be located in nail bin and percussion sheet and the cutting knife that can move relative to described nail bin simultaneously, and be used for driving the push button that described percussion sheet and cutting knife move.Be disposed with suturing nail in described nail bin, described percussion sheet promotes in order successively pushing slice of nail and pushes suturing nail to nail anvil, and described cutting knife cuts off the tissue between nail bin and nail anvil.
Nail bin frame on existing Linear seam cutting device is provided with the spacing preiection of a metal material, and this spacing preiection contacts with closed handle, thereby closed handle is realized spacing.But on the Linear seam cutting device that generally uses at present, spacing preiection is the line contact with contacting of closed handle, and is that metal contacts with the direct of metal.When Linear seam cutting device was opened, contact gear ratio was more stiff, caused the user feel bad.
The utility model content
The purpose of this utility model is to propose a kind of Linear seam cutting device simple in structure, by the improvement to structure, has improved the comfort when apparatus is opened.
The purpose of this utility model will be achieved by the following technical programs:
A kind of Linear seam cutting device, comprise the nail anvil and the nail bin that are oppositely arranged, described nail bin is located in a nail bin frame, and described nail bin frame and closed handle are pivotally connected, be provided with spacing preiection near described closed handle place on described nail bin frame, described spacing preiection outside is provided with a cushion collar.
Preferably, described closed handle side corresponding position offers arcuate groove, and the gabarit of described arcuate groove and described spacing preiection matches, and the cushion collar of described spacing preiection outside contacts with described arc groove face.
Preferably, described cushion collar is rubber sleeve.
Preferably, between described rubber sleeve and spacing preiection be tight fit or bonding.
Preferably, described cushion collar is the medical glue-line that is coated on described spacing preiection.
The beneficial effects of the utility model are mainly reflected in: by offering arcuate groove in the position of the corresponding spacing preiection of closed handle side, this arcuate groove contacts with the spacing preiection face, and cushion collar is set up in the outside at spacing preiection, has improved the comfort of Linear seam cutting device.
Description of drawings
Fig. 1 is the structural representation of this utility model Linear seam cutting device.
Fig. 2 is the enlarged diagram of A part in Fig. 1.
Wherein: 1, nail anvil; 2, nail bin; 3, nail anvil shell; 4, nail bin frame; 5, closed handle; 51, arcuate groove; 6, spacing preiection; 7, rubber sleeve.
The specific embodiment
As depicted in figs. 1 and 2, a kind of Linear seam cutting device that this utility model discloses comprises the nail anvil 1 and the nail bin 2 that are oppositely arranged, and described nail anvil 1 outer surface is provided with nail anvil shell 3, described nail bin 2 is located in a nail bin frame 4, and described nail bin frame 4 is pivotally connected with closed handle 5.On described nail bin frame 4, nearly described closed handle 5 places are provided with spacing preiection 6, be engaged in described closed handle 5 side corresponding positions with the gabarit of described spacing preiection 6 and offer arcuate groove 51, described spacing preiection 6 contacts with 51 of described arcuate grooves, has improved the comfort level of instrumentation.
In preferred embodiment of the present utility model, also set up a cushion collar in the outside of spacing preiection, this cushion collar can be rubber sleeve 7, and being connected between rubber sleeve 7 and spacing preiection 6 can be the modes such as bonding, injection moulding or spiral connection, can certainly be the simplest tight fit.Described cushion collar can also be for being coated on the medical glue-line on described spacing preiection, the impact that can play when alleviating spacing preiection and contacting with closed handle gets final product, therefore, existence due to cushion collar, make coordinating for flexible between spacing preiection and closed handle coordinate, make the use feel of Linear seam cutting device better.
This utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection domain of the present utility model.
