A kind of novel stiching instrumentTechnical field
This utility model belongs to medical instruments field, particularly coincide the stiching instrument that stitching or cutting and stitching are used in the surgical operation.
Background technology
Improving constantly along with China's scientific and technological level in recent years, at the continuous improvement of the design and fabrication technology of disposable use stiching instrument product and perfect, it progressively substitutes the manual suture, is extensively applied in the operations such as stomach, intestinal, the lobe of the lung, pancreas, hemorrhoid mucosa; Its advantage of this product is easy and simple to handle, shortens operating time, reduces amount of bleeding, and it is few that operation wound gently reaches complication, therefore is subjected to liking of numerous doctors and patient deeply.
In the use of stiching instrument, guarantee that whether successful suturing nail can correctly be configured as " B " font is suture operation key factor when coincideing.If suturing nail is configured as " C " font, then can sternly not cause operative failure because of the contact of both sides tissue wall.Yet, present widely used stiching instrument, because the imperfection of project organization, the doctor is when doing suture operation, can not accurately understand and obtain the progress degree when sewing up, judge by doctor's intuition and experience whether stitching is finished at last, so easy combined influence because of objective factors such as subjective factors and environment, stitching resistances makes suturing nail form bad structure, thereby cause bad complication, bring unnecessary painful and trouble to patient.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of novel stiching instrument that has the position indicating device is provided, and is used for eliminating because of the subjectivity operation causes sewing up bad influence.
For solving the problems of the technologies described above, a kind of stiching instrument of the present utility model comprises casing, spanner, by the push rod of spanner control, and what link to each other with push rod infers sheet, nail bin, and the nail supporting base of nail bin para-position, and described pushing slice of nail is positioned at the nail bin rear end and pegs graft with nail bin; During stitching, described spanner drives pushing slice of nail, push rod is done ahead running to the nail supporting base direction in casing, this stiching instrument also is provided with the position indicating device, two switch contacts of the circuits for triggering of described position indicating device are located at respectively on above-mentioned two devices with relative motion relation, and when triggered two contacts, the suturing nail in the nail bin formed " B " font structure.
This utility model is perfect by above-mentioned improvement and structure, the person can learn accurately, objectively whether suture operation is finished to make the operation technique, whether avoided the doctor to weigh operation because of subjective judgment finishes in the past, not only improved the efficient of operation greatly, alleviated doctor's pressure, and impel the success rate of operation to improve greatly, and promote the healing of wound, alleviated the misery of patient's postoperative.
As preferred embodiment of the present utility model: described two contacts are located at respectively infers on sheet and the nail supporting base, by the relative motion of inferring sheet and nail supporting base, and rely on suturing nail and the special relationship of inferring sheet, can further improve the synchronicity of sewing up and triggering, guarantee the precision of performing the operation.
As another preferred embodiment of the present utility model: described two contacts are located at respectively on casing and the push rod.
And the prompting apparatus that relates in the device of position indicating described in this utility model is chosen as general-purpose devices such as voice prompting device or diode.
This utility model can improve on the basis of original structure, and is simple in structure, easily manufactured, has higher utility.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Embodiment 1: as shown in Figure 1 and Figure 2: a kind of novel stiching instrument, comprisecasing 5,adjustable wrench 6, by thecurved push rod 4 ofadjustable wrench 6 controls, what link to each other withcurved push rod 4infers sheet 3,nail bin 2, with thenail supporting base 1 and the position indicating device 7 of nail bin para-position, wherein pushing slice ofnail 3 is positioned atnail bin 2 rear ends and pegs graft with nail bin; Two switch contact 7-31 of the circuits for triggering of position indicating device and 7-31 ' are located at respectively oncasing 5 and thecurved push rod 4, and the length that the distance between two contacts equals suturing nail nail lower limb in the nail bin deducts the degree of depth of nail groove on the nail supporting base; During stitching, do ahead running tonail supporting base 1 direction byadjustable wrench 6 drive pushing slice ofnail 3,push rod 4 incasing 5, when the suturing nail in thenail bin 2 formed " B " font structure, two contact 7-31 just in time contacted with 7-31 ', circuits for triggering constitute the loop, excite suggestion device work.
As shown in Figure 3: described position indicating device is composed in series by power supply, resistance 7-1, trigger switch 7-3 and diode 7-2, when two contact 7-31 of trigger switch contact with 7-31 ', lights diode 7-2.
Embodiment 2: as shown in Figure 4: a kind of novel stiching instrument, comprisecasing 5, back-up wrench,adjustable wrench 6,nail bin 2, pushing slice ofnail 3,push rod 4,nail supporting base 1, and position indicating device 7, pushing slice ofnail 3 is positioned at the nail bin rear end and pegs graft with nail bin,nail supporting base 1 is positioned at the front side of nail bin, and it is corresponding with nail bin that its work surface is provided with the nail groove; Two the switch contact 7-31 and the 7-31 ' of the circuits for triggering of position indicating device are located on the inboard and pushing slice ofnail 3 ofnail supporting base 1 no suturing nail in the pairing nail bin of the switch contact 7-31 ' unit respectively; When stitching excites, do ahead running tonail supporting base 1 direction byadjustable wrench 6 drive pushing slice ofnail 3,push rod 4 incasing 5, when the suturing nail in thenail bin 2 formed " B " font structure, two contact 7-31 just in time contacted with 7-31 ', circuits for triggering constitute the loop, excite suggestion device work.
As shown in Figure 5: described position indicating device is composed in series by power supply, resistance 7-1, trigger switch 7-3 and loudspeaker 7-4, when two contact 7-31 of trigger switch contact with 7-31 ', and loudspeaker 7-4 voice suggestion.
This utility model improves on the basis that does not change original structure and adds assembly, makes the stiching instrument more perfect function, and is more convenient to operate, has very high practicality.
