Abstract
The invention discloses a kind of stapler-type endoscopic suture devices, it will need the tissue sutured to be stitched together using sewing needle, the sewing needle includes middle part and is located at the needle point at middle part both ends, the sewing needle is made of memorial alloy, its reset condition is that two needle points are connected together, and two needle points of the sewing needle can be softened separation；Using the driver in stitching unstrument by two needle points of sewing needle strut and reach needle point penetrate the position of tissue when drive so that sewing needle penetrate tissue and restore reset condition come realize suture.By the present invention in that with stapler-type stitching unstrument by wound or the mode of tissue one needle, one needle stitching, method is novel, easy to operate, overcomes the problems, such as to be easy to cause undesirable wound to tissue in traditional suture way.
Description
Technical field
The present invention relates to a kind of surgical instrument more particularly to a kind of stapler-type endoscopic suture devices.
Background technology
Currently, when needing to sew up a wound or connect tissue, the sewing needle generally used is needle bent, is sutured by rotating
Needle is sutured.But when carrying out space and the internal medicine operation having tunnel vision, this suture way is not easy to operate, and easy pair
Tissue or wound damage, and the sewing needle of bending needs to enter by scope first, it is also necessary to be inserted into nipper to do a good job of it tissue
Or the both sides of wound, it reuses pliers and sewing needle is caught to carry out rotation suture.Therefore, the sewing needle of operating difficulties, bending also holds
Undesirable damage easily is caused to tissue or wound.
Invention content
The present invention provides a kind of stapler-type endoscopic suture devices, and which overcome endoscopic surgery sutures in background technology to be deposited
Deficiency.
The used technical solution that the present invention solves its technical problem is：
A kind of stapler-type endoscopic suture device is mounted in hyaline cap, the tissue for being sutured needs using sewing needle
It is stitched together, the sewing needle includes middle part and is located at the needle point at middle part both ends, and the sewing needle is closed by memory
Gold is made, and reset condition is that two needle points are connected together, and two needle points of the sewing needle can be softened separation；Utilize peace
Driver in stitching unstrument two needle points of sewing needle are strutted and are driven when reaching needle point and penetrating the position of tissue with
So that sewing needle is penetrated tissue and restores reset condition to realize suture.
In a further preferred embodiment, the driver includes with there are two the conduit of needle point baffle, and baffle is relative to slot
Road is moved back and forth between operating position and releasing position with predetermined direction.
In a further preferred embodiment, the conduit is annulus, and sleeve is equipped with the trepanning of the corresponding needle point.
In a further preferred embodiment, it is connected using spring between two needle point baffles, two baffles move toward one another.Driving
What two baffles moved is drawstring.
In a further preferred embodiment, it is additionally provided in conduit and limits the fixation wall that baffle moves to operating position.
In a further preferred embodiment, the reset condition of the sewing needle is circle, a diameter of 8mm.
Compared with the background art, it has the following advantages that the technical program：
1, by using stapler-type stitching unstrument by wound or the mode of tissue one needle, one needle stitching, method is novel, operation
Simply, overcome the problems, such as to be easy to cause undesirable wound to tissue in traditional suture way.
2, sewing needle is simple in structure and novel, using it suture easy to operate.
3, activation configuration is simple, and it is releasable sewing needle to be pulled using drawstring.
4, spring can be such that baffle restores automatically, facilitate the preparation of next needle.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the stitching unstrument of the present invention.
Fig. 2 is the sectional view one of the stitching unstrument in Fig. 1, and sewing needle is in and is softened state at this time.

Fig. 5 is the structural schematic diagram two of the sewing needle of the present invention, and sewing needle is in original state at this time.
Fig. 6 is the design sketch using the staplers wound of the present invention.
Specific implementation mode
Embodiment, please refers to Fig. 1 to Fig. 5, and a kind of stapler-type endoscopic suture device will need to suture using sewing needle 1
Tissue be stitched together, the sewing needle 1 includes middle part 12 and is located at the needle point 13 at middle part both ends, the suture
Needle 1 is made of memorial alloy, and reset condition is that two needle points are connected together, as shown in figure 5, sewing needle 1 is circular stapler
Needle, when reset condition a diameter of 8mm；Two needle points 13 of the sewing needle 1 can be softened separation, as shown in Figure 4；Utilize installation
Two needle points 13 of sewing needle 1 are strutted and are driven when reaching needle point 13 and penetrating the position of tissue by the driver in stitching unstrument
So that sewing needle 1 penetrates tissue and restores reset condition to realize that suture, sewing effect figure are shown in Figure 6.In scope hand
In art, which is mounted in hyaline cap 3, and hyaline cap 3 can be connected on inner lens biopsy pipeline.
In the present embodiment, the driver includes with there are two the conduit of needle point baffle 21, and baffle 21 exists relative to conduit
It is moved back and forth with predetermined direction between operating position and releasing position.Two needle points 13 of sewing needle 1 are softened and are located first
Two baffles 21 in operating position strut fixation, and sewing needle 1 is Curved at this time, when two baffles 21 move simultaneously in conduit
The blocking to two needle points 13 is released, sewing needle 1 is released to penetrate tissue and be restored to its reset condition to realize suture.
In the present embodiment, the conduit be annulus 22, be fixed in hyaline cap 3, annulus 22 be equipped with pair
Answer the trepanning 23 of the needle point 13.It is connected using spring 24 between two needle point baffles 21, so that two baffles 21 borrow elastic force extensive
Again in its operating position, two baffles 21 move toward one another in sleeve 22.What two baffles 21 of driving moved is drawstring 25, sleeve
22 are equipped with the hole 26 of the corresponding drawstring 25.It is additionally provided in sleeve 22 and limits the fixation wall that baffle 21 moves to operating position
27。
Using the present embodiment staplers wound or tissue when, wound both sides skin is flipped up with tissue clamps,
And draw fitting over to one's side, by stitching unstrument perpendicular alignmnet, drawstring 25 is pulled, two needle point baffles 21 are moved toward one another in sleeve 22, and are released
Blocking to two needle points 13, sewing needle 1 are released to penetrate tissue and revert to circle shape to sew up a wound, simultaneously because
The effect of spring 24, two movements of baffle 21 return, and under the limit of fixed wall, its operating position are stopped at, to carry out down
The preparation of one needle.
It is found that in addition to the implementation, the present invention can also realize consolidating for sewing needle 1 using the driver of other structures
Fixed and release, for example, the direction of motion of baffle is instead of as embodiment is vertical with the axis direction of hyaline cap, the axis with hyaline cap
Direction is parallel or intersects, and the direction of motion of two baffles is not opposite but identical.
The above, only present pre-ferred embodiments, therefore cannot limit the scope of implementation of the present invention according to this, i.e., according to
Equivalent changes and modifications made by the scope of the claims of the present invention and description all should still belong in the range of the present invention covers.
