The medical straight stitching and cutting instrument has the beneficial effects that by additionally arranging the nail bin positioning mechanism, the nail bin and the nail bin frame are better positioned and fixed and even though the nail bin and the nail bin frame are not installed in place by a doctor, the near end of the nail bin cannot enter the nail bin frame so as to be timely found by the doctor; and the condition that the nail bin is not installed in place by the doctor is avoided.
Description
Technical field
The present invention relates to a kind of medical stapling instrument, the straight line seaming and cutting device that especially a kind of surgical operation is used belongs to technical field of medical instruments.
Background technology
The 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 such as US Patent No. 5129570 announcements, have simultaneously and sew up and cut two functions, namely when carrying out wound suture, excess tissue is excised.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 the closed handle that is used for closed upper and lower clamp; Being provided with in this nail bin can be along apparatus axis mobile ejector pin bar and the far-end push broach bar that is provided with cutting knife simultaneously, and an end of described ejector pin bar and push broach bar all is equipped on the slide block; Described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and suturing nail in each nail hole; Described slide block moves and drives described ejector pin bar and promote pushing slice of nail successively and push described suturing nail to nail anvil to form in and treat on the suture tissue, and drives described cutting knife the tissue between described nail bin and nail anvil is cut off or otch.
Nail bin and seaming and cutting device are dismountable, after the doctor finishes using for the first time, nail bin can be unloaded, in the clamp of then new nail bin being packed into.But because nail bin and clamp if do not find, then can influence the success rate of operation often because doctor's installation is not in place; Sometimes even can cause the seaming and cutting device to damage, and the process of influence operation.
Summary of the invention
Purpose of the present invention solves the problems of the technologies described above, and proposes a kind of medical linear sewing and cutting machine with nail bin detent mechanism, and this detent mechanism can well guide nail bin to insert in the nail bin frame, has avoided the installation of nail bin not in place.
Purpose of the present invention will be achieved by the following technical programs:
A kind of medical linear sewing and cutting machine comprises: can be mutually the closed or upper and lower clamp opened, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end and the closed handle that is used for closed upper and lower clamp; Described nail bin is arranged on down in the nail bin frame of clamp far-end, and described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and the suturing nail of mutual butt in each nail hole; Described seaming and cutting device is provided with the nail bin detent mechanism, described detent mechanism is arranged on the contact surface of nail bin and nail bin frame, described detent mechanism comprises a location boss and the locating slot that matches with positioning boss, between the detent mechanism on the nail bin is arranged on apart from nail bin near-end 5-25mm.
Preferably, described positioning boss is convexly equipped with at described nail bin frame inner surface, and described locating slot is opened in the nail bin side.
Preferably, described positioning boss is arranged on the 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 the nail bin detent mechanism, make better to locate to reach between nail bin and the nail bin frame and fix, even when doctor's nail bin and nail bin frame are installed when not in place, because the tail end of nail bin can't enter the nail bin frame and in time be found by the doctor.Avoided the doctor that nail bin situation not in place is installed.

The specific embodiment
The present invention has disclosed the medical linear sewing and cutting machine, comprising: can be mutually the closed or upper and lower clamp opened, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end and the closed handle that is used for closed upper and lower clamp; Described nail bin is arranged on down in the nail bin frame of clamp far-end, and described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and the suturing nail of mutual butt in each nail hole.
Shown in Fig. 1-4, described seaming and cutting device is provided with the nail bin detent mechanism, and detent mechanism is arranged on the contact surface of nail bin and nail bin frame.Described detent mechanism comprises a location boss and the locating slot that matches with positioning boss, as shown in Figure 2, when described positioning boss 11 is convexly equipped with at described nail bin frame 1 inner surface, described locating slot 21 is opened in nail bin 2 sides, between the locating slot 21 on the nail bin is arranged on apart from nail bin near-end 5-25mm, an end in especially close nail bin hole.
Certainly, described positioning boss also can be arranged on the side of nail bin 2, and at this moment, described locating slot is opened in the inner surface of described nail bin frame 1.
In the time of in nail bin 2 places nail bin frame 1, positioning boss 11 mates mutually with locating slot 21, embeds in the locating slot 21.
Shown in Fig. 5-6, not in place if nail bin 2 is installed, the near-end that then is easy to generate nail bin 2 can't enter in the nail bin frame 1, causes the perk of nail bin near-end.At this moment, positioning boss 11 can not enter into locating slot 21 smoothly, and the operator is very easy to find setup error, in order in time correct.
Have only positioning boss 11 to be embedded in the locating slot 21, shown in Fig. 7-8, at this moment, nail bin enters into the nail bin frame smoothly, and the nail bin upper surface flushes with nail bin frame end face.
Below sketch installation method of the present invention down:
During installation, the far-end of nail bin 2 is cooperated with the far-end of nail bin frame 1 to put in place earlier, and then depress the near-end of nail bin 2, at this moment, the locating slot 21 on the nail bin 2 matches with boss 11 on the nail bin frame 1, the nail bin 2 nail bin frame 1 of can packing into smoothly; If nail bin 2 is not installed in this way, the boss 11 on the nail bin frame 1 can make nail bin 2 perks, and the doctor can be very easy to find faulty operation, and then change in time.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
