Abstract
The invention discloses a kind of rotatable stapler-type endoscopic suture devices, it is mounted in hyaline cap, it will need the tissue sutured to be stitched together using sewing needle, the sewing needle includes middle part and the needle point for being located 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 rotatable driver being mounted 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 method is novel with stapler-type stitching unstrument by wound or the mode of tissue one needle, one needle stitching, and it is easy to operate, overcome the problems, such as to be easy to cause tissue undesirable wound in traditional suture way；And driver is rotatable in hyaline cap, achievees the purpose that adjust sewing needle direction.
Description
Technical field
The present invention relates to a kind of surgical instrument more particularly to a kind of rotatable stapler-type endoscopic suture devices.
Background technique
Currently, the sewing needle generally used is needle bent when needing to sew up a wound or connect tissue, sutured by rotation
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 curved sewing needle 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, operating difficulties, curved sewing needle also hold
Undesirable damage easily is caused to tissue or wound.
Summary of the invention
The present invention provides a kind of rotatable stapler-type endoscopic suture devices, and which overcome endoscopic surgeries in background technique
The existing deficiency of suture.
The used technical solution that the present invention solves its technical problem is:
A kind of rotatable stapler-type endoscopic suture device, is mounted in hyaline cap, will need to stitch using sewing needle
The tissue of conjunction is stitched together, and the sewing needle includes middle part and the needle point for being located at middle part both ends, the sewing needle
It is made of memorial alloy, reset condition is that two needle points are connected together, and two needle points of the sewing needle can be softened point
From；Two needle points of sewing needle are strutted using the rotatable driver being mounted in stitching unstrument and penetrate group reaching needle point
It is driven when the position knitted so that sewing needle penetrates tissue and restores reset condition to realize suture.
In a further preferred embodiment, the driver includes the punch block equipped at least two sewing needle clips, and punch block exists
Rotatable in hyaline cap, the clip struts sewing needle and when clip is opened for clamping sewing needle to discharge suture
Needle.
In a further preferred embodiment, the sewing needle clip is three or more.
In a further preferred embodiment, the clip includes an open annular sleeve, and sewing needle can be put into set by opening
In cylinder, fixed pedestal and the movable sewing needle baffle for opening and closing opening are equipped in annulus, baffle is logical
It crosses spring connection on the base, is additionally provided with drawstring to drive baffle movable.
In a further preferred embodiment, the reset condition of the sewing needle is circle, diameter 8mm.
The technical program compared with the background art, it has the following advantages:
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 tissue undesirable wound in traditional suture way；And driver can in hyaline cap
Rotation achievees the purpose that adjust sewing needle direction.
2, suture needle construction is simple and novel, suture using it easy to operate.
3, sewing needle is clamped using the mode of multiple clips, clamping is stablized, and release settles at one go.
4, activation configuration is simple, and being pulled using drawstring is releasable sewing needle.
5, spring can be such that baffle restores automatically, facilitate the preparation of next needle.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.

Specific embodiment
Embodiment, please refers to Fig. 1 to Fig. 5, and a kind of rotatable stapler-type endoscopic suture device uses sewing needle 1 will
The tissue for needing to suture is stitched together, and the sewing needle 1 includes middle part 12 and the needle point 13 for being located at middle part both ends,
The sewing 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, diameter is 8mm when reset condition；Two needle points 13 of the sewing needle 1 can be softened separation, as shown in Figure 4；
Two needle points 13 of sewing needle 1 are strutted using the rotatable driver being mounted in stitching unstrument and are penetrated reaching needle point 13
When the position of tissue drive so that sewing needle 1 penetrate tissue and restore reset condition come realize suture, sewing effect figure referring to
Shown in Fig. 6.In endoscopic surgery, which is mounted in hyaline cap 3, and hyaline cap 3 can connect in inner lens biopsy pipe
On road.
In the present embodiment, the driver includes the punch block 4 equipped at least two sewing needle clips 2, and punch block 4 is in hyaline cap
Rotatable in 3, the clip 2 struts sewing needle 1 and when clip 2 is opened for clamping sewing needle 1 to discharge sewing needle
1.Two needle points 13 of sewing needle 1 are softened first and are gripped by clip 2, and sewing needle 1 is Curved at this time, when clip 2
The blocking to two needle points 13 is opened and releases, sewing needle 1 is released to penetrate tissue and be restored to its reset condition to realize
Suture.
The sewing needle clip 2 is preferably three and three or more.In the present embodiment, the quantity of clip 2 is 4.
The clip 2 includes an open annular sleeve 21, and sewing needle 1 can be put into sleeve 21 by opening 22, annular sleeve
Fixed pedestal 23 and the movable sewing needle baffle 24 for opening and closing opening 22 are equipped in cylinder 21, baffle 24 is to pass through
Spring 25 is connected on pedestal 23, is additionally provided with drawstring 26 to drive baffle 24 movable.
Using the present embodiment staplers wound or tissue when, wound two sides skin is flipped up with tissue clamps,
And draw fitting over to one's side, and by stitching unstrument perpendicular alignmnet, drawstring 26 is pulled, the baffle 24 in sleeve 21 is pulled to open opening 22, and
Releasing grips sewing needle needle body, and sewing needle 1 is released to penetrate tissue and revert to circle shape to sew up a wound,
Simultaneously because the effect of spring 25, the movement of baffle 24 is returned, and under the limit of pedestal, stops at its operating position, to carry out
The preparation of next 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 is only the preferred embodiment of the present invention, the range implemented of the present invention that therefore, it cannot be limited according to, i.e., according to
Equivalent changes and modifications made by the invention patent range and description, should still be within the scope of the present invention.
