At present, when needs are sewed up a wound or connect tissue, the sewing needle generally used is needle bent, by rotation
Turn sewing needle to sew up.But when the internal medicine operation carrying out space and have tunnel vision, this suture way is not
Easily operation, and easily tissue or wound are caused damage, the sewing needle of bending needs to first pass through scope and enters,
Also need to insert nipper to do a good job of it the both sides of tissue or wound, re-use pliers catch sewing needle carry out rotate stitching.
Therefore, operating difficulties, the sewing needle of bending is also easy to tissue or wound are caused less desirable infringement.
Summary of the invention
The invention provides a kind of rotatable stapler-type endoscopic suture device, which overcome scope in background technology
Deficiency existing for operation stitching.
The present invention solves being the technical scheme is that of its technical problem
A kind of rotatable stapler-type endoscopic suture device, it is arranged in hyaline cap, and it uses sewing needle need to
Together, described sewing needle includes pars intermedia and lays respectively at the needle point at pars intermedia two ends tissue apposition to be sewed up,
Described sewing needle is made up of memorial alloy, and its reset condition is that two needle points are connected together, described sewing needle
Two needle points can softened separate；Utilize the driver walked around being arranged in stitching unstrument by the two of sewing needle
Needle point struts and drives so that sewing needle penetrates tissue and recovers original shape when arrival needle point penetrates the position of tissue
State realizes sewing up.
In a further preferred embodiment, described driver includes the punch block being furnished with at least two sewing needle clip, pin
Frame is rotatable in hyaline cap, and described clip is used for clamping sewing needle to strut sewing needle and when clip is opened
To discharge sewing needle.
In a further preferred embodiment, described sewing needle clip is preferably three and more than three.
In a further preferred embodiment, described clip includes an open annular sleeve, and sewing needle can be put by opening
Enter in sleeve, in annulus, be provided with fixing pedestal and the movable sewing needle gear for opening and closing opening
Plate, baffle plate is to be connected on pedestal by spring, is additionally provided with stay cord to drive baffle plate movable.
In a further preferred embodiment, the reset condition of described sewing needle is circular, a diameter of 8mm.
The technical program is compared with background technology, and it has the advantage that
1, by the way of using stapler-type stitching unstrument by wound or tissue one pin one pin stitching, method is novel,
Simple to operate, overcome the problem easily tissue being caused undesirably wound in tradition suture way；And driver
In hyaline cap rotatable, reach adjust sewing needle direction purpose.
2, sewing needle simple in construction is the most novel, uses it to carry out sewing up easy to operate.
3, using the mode of multiple clip to clamp sewing needle, clamping is stable, and release settles at one go.
4, activation configuration is simple, uses stay cord to pull i.e. releasable sewing needle.
5, spring can make baffle plate automatically recover, and facilitates the preparation of next pin.

Detailed description of the invention
Embodiment, refer to Fig. 1 to Fig. 5, and a kind of rotatable stapler-type endoscopic suture device, it uses seam
Closing pin 1 and will need the tissue apposition of stitching together, described sewing needle 1 includes pars intermedia 12 and lays respectively at
The needle point 13 at pars intermedia two ends, described sewing needle 1 is made up of memorial alloy, and its reset condition is two needle points
It is connected together, as it is shown in figure 5, sewing needle 1 is circular stapler pin, a diameter of 8mm during reset condition；Institute
Two needle points 13 stating sewing needle 1 can softened separate, as shown in Figure 4；Utilize and be arranged in stitching unstrument
Two needle points 13 of sewing needle 1 are strutted and penetrate the position of tissue at arrival needle point 13 by rotatable driver
When putting drive so that sewing needle 1 penetrate tissue and recover reset condition realize sew up, its sewing effect figure ginseng
As shown in Figure 6.In endoscopic surgery, this stitching unstrument is mounted in hyaline cap 3, and hyaline cap 3 can connect
It is connected on inner lens biopsy pipeline.
In the present embodiment, described driver includes the punch block 4 being furnished with at least two sewing needle clip 2, punch block 4
In hyaline cap 3 rotatable, described clip 2 is used for clamping sewing needle 1 to strut sewing needle 1 and at folder
To discharge sewing needle 1 when button 2 is opened.Two needle points 13 of sewing needle 1 are the most softened and pressed from both sides by clip 2
Holding fixing, now sewing needle 1 is Curved, when the stop to two needle points 13 is opened and released to clip 2,
Sewing needle 1 is released penetrate tissue and return to its reset condition to realize sewing up.
Described sewing needle clip 2 is preferably three and more than three.In the present embodiment, the quantity of clip 2 is 4.
Described clip 2 includes an open annular sleeve 21, and sewing needle 1 can put into sleeve 21 by opening 22,
Fixing pedestal 23 and the movable sewing needle baffle plate for opening and closing opening 22 it is provided with in annulus 21
24, baffle plate 24 is to be connected on pedestal 23 by spring 25, is additionally provided with stay cord 26 to drive baffle plate 24 movable.
When using staplers wound or the tissue of the present embodiment, with tissue clamps by wound both sides skin upwards
Upset, and draw laminating over to one's side, by stitching unstrument perpendicular alignmnet, pull stay cord 26, baffle plate 24 quilt in sleeve 21
Pulling to open opening 22, and release and grip sewing needle needle body, sewing needle 1 is released to penetrate
Organizing and revert to circle shape to sew up a wound, simultaneously because the effect of spring 25, baffle plate 24 motion is returned
Return, and pedestal spacing under, stop at its operating position, to carry out the preparation of next pin.
Understanding, in addition to the implementation, the present invention can also use the driver of other structures to realize sewing up
Fixing and the release of pin 1, such as, the direction of motion of baffle plate is not that the direction of principal axis such as embodiment with hyaline cap hangs down
