The invention discloses a medical linear suturing and cutting instrument, which comprises: the nail-cutting device comprises an upper clamp, a lower clamp, a nail anvil, a nail bin and a closing handle, wherein the upper clamp and the lower clamp can be mutually closed or opened; the nail bin is arranged in a nail bin frame at the far end of the lower forceps clip, a plurality of nail holes are arranged on the surface of the nail bin along the axis of the instrument, and a nail pushing sheet and a suturing nail which are mutually abutted are arranged in each nail hole; the stitching and cutting device is provided with a nail bin positioning mechanism, the positioning mechanism is arranged on the contact surface of the nail bin and the nail bin frame, and the positioning mechanism comprises a positioning boss and a positioning groove matched with the positioning boss. The invention has the beneficial effects that: through increasing nail storehouse positioning mechanism for better location and fixed between nail storehouse and the nail storehouse frame, even when doctor's nail storehouse and the installation of nail storehouse frame are not in place, because the near-end of nail storehouse can't get into the nail storehouse frame and in time be discovered by the doctor. The condition that a doctor does not install the nail bin in place is avoided.
Description
Technical field
The present invention relates to a kind of medical stapling instrument, especially a kind of Linear stapling cutter of surgical operation, belongs to technical field of medical instruments.
Background technology
Medical linear sewing and cutting machine is widely used in wound suture, interior tissue is sewed up and cutting.Typical medical linear sewing and cutting machine as US Patent No. 5129570 disclose, have simultaneously sew up with cutting two functions, namely while carrying out wound suture by unnecessary cutting tissue.Such medical linear sewing and cutting machine generally comprises upper and lower two clamps, is oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, and for closing the closed handle of upper and lower clamp; Be provided with the push broach bar that can be provided with cutting knife along the ejector pin bar of apparatus axis movement simultaneously and far-end in this nail bin, one end of described ejector pin bar and push broach bar is all disposed on a slide block; Described nail bin surface is provided with several nail along the arrangement of apparatus axis, is provided with pushing slice of nail and suturing nail in each nail; Described slide block moves and drives described ejector pin bar to promote pushing slice of nail successively and push described suturing nail to nail anvil to form in tissue to be stapled, and drives described cutting knife to be cut off or otch by the tissue between described nail bin and nail anvil.
Nail bin and seam cutter are dismountable, after doctor finishes using first time, nail bin can be unloaded, then be loaded in clamp by new nail bin.But because nail bin and clamp are often because the installation of doctor is not in place, if do not find, then the success rate of operation can be affected; Sometimes seam cutter even can be caused to damage, and the process of impact operation.
Summary of the invention
Object of the present invention solves the problems of the technologies described above, and propose a kind of medical linear sewing and cutting machine with nail bin detent mechanism, this detent mechanism can well guide nail bin to insert in nail bin frame, and the installation avoiding nail bin is not in place.
Object of the present invention, will be achieved by the following technical programs:
A kind of medical linear sewing and cutting machine, comprising: the upper and lower clamp that can mutually close or open, is oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, and for closing the closed handle of upper and lower clamp; Described nail bin is arranged in the nail bin frame of lower clamp far-end, and described nail bin surface is provided with several nail along the arrangement of apparatus axis, is provided with the pushing slice of nail and suturing nail that mutually abut in each nail; Described seam cutter is provided with nail bin detent mechanism, described detent mechanism is arranged on the contact surface of nail bin and nail bin frame, the locating slot that described detent mechanism comprises a positioning boss and matches with positioning boss, the detent mechanism on nail bin is arranged between distance nail bin near-end 5-25mm.
Preferably, described positioning boss projection is at described nail bin frame inner surface, and described locating slot is opened in nail bin side.
Preferably, described positioning boss is arranged on nail bin side, and described locating slot is opened in the inner surface of described nail bin frame.
Beneficial effect of the present invention is mainly reflected in: by increasing nail bin detent mechanism, make better to locate between nail bin and nail bin frame and fix, even if when doctor's nail bin and nail bin frame are installed not in place, the tail end due to nail bin cannot enter nail bin frame and by doctor's Timeliness coverage.Avoid doctor and nail bin situation not in place is installed.

Detailed description of the invention
Present invention is disclosed medical linear sewing and cutting machine, comprising: the upper and lower clamp that can mutually close or open, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, and for closing the closed handle of upper and lower clamp; Described nail bin is arranged in the nail bin frame of lower clamp far-end, and described nail bin surface is provided with several nail along the arrangement of apparatus axis, is provided with the pushing slice of nail and suturing nail that mutually abut in each nail.
As Figure 1-4, described seam cutter is provided with nail bin detent mechanism, detent mechanism is arranged on the contact surface of nail bin and nail bin frame.The locating slot that described detent mechanism comprises a positioning boss and matches with positioning boss, as shown in Figure 2, when the projection of described positioning boss 11 is at described nail bin frame 1 inner surface, described locating slot 21 is opened in nail bin 2 side, locating slot 21 on nail bin is arranged between distance nail bin near-end 5-25mm, especially near the one end in nail bin hole.
Certainly, described positioning boss also can be arranged on the side of nail bin 2, and now, described locating slot is opened in the inner surface of described nail bin frame 1.
When nail bin 2 is placed in nail bin frame 1, positioning boss 11 mates mutually with locating slot 21, embeds in locating slot 21.
Shown in composition graphs 5-6, if nail bin 2 is installed not in place, then the near-end easily producing nail bin 2 cannot enter in nail bin frame 1, causes nail bin near-end to tilt.Now, positioning boss 11 can not enter into locating slot 21 smoothly, and operator is very easy to find setup error, to correct in time.
Only have positioning boss 11 to be embedded in locating slot 21, shown in composition graphs 7-8, now, nail bin enters into nail bin frame smoothly, nail bin upper surface and nail bin frame end face.
The below lower installation method of the present invention of summary:
During installation, first coordinated with the far-end of nail bin frame 1 by the far-end of nail bin 2 and put in place, and then depress the near-end of nail bin 2, now, the locating slot 21 on nail bin 2 matches with the boss 11 on nail bin frame 1, and nail bin 2 can load nail bin frame 1 smoothly; If do not install nail bin 2 in this way, the boss 11 on nail bin frame 1 can make nail bin 2 tilt, and doctor can be very easy to find faulty operation, and then changes in time.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
