Description
Technical field
The invention belongs to technical field of medical instruments, and in particular to a kind of soft tissue set based on marmem cuts kiss
Clutch.
Background technology
In hemorrhoid in the treatment operation of mucous membrane or internal piles, elastic rubber snare the bundles technology that clinically uses at present or identical
Device technology is used for hemorrhoid treating, is such as pricked mucous membrane in hemorrhoid or internal piles set using rubber ring when mucous membrane on doing hemorrhoid or internal piles are cut off,
Or the modus operandi cut off after being pegged mucous membrane in hemorrhoid or internal piles using stainless steel lag screws or titanium nail.Elastic rubber circle is due to material
Reason set bundle dynamics is inadequate, easily comes off, and because quality of rubber materials level of stretch is limited, can not cover sufficiently large set and prick model
Enclose, multiple elastic rubber circles are needed to use in an operation, stability is relatively low.And stainless steel or titanium nail are cut after mucous membrane is pegged
The operation removed, because the device is invasive surgery apparatus, patient will suffer exquisite pain, and stainless steel lag screws or titanium nail will be long
Phase is trapped in human body, may cause operative failure and sequelae.
The content of the invention
It is an object of the present invention to provide a kind of soft tissue set based on marmem to cut stapler, solves existing people
The existing set bundle dynamics of body soft tissue ligation instrument is inadequate, set pricks the technical problem that scope is small, stability is poor.
The present invention technical solution be：A kind of soft tissue set based on marmem cuts stapler, and its is special
Part is：Connection sheet including at least three close out sheet and with close out sheet quantity identical C fonts, the close out sheet include two
Individual to connect first section for forming V-shape structure, adjacent first section of two close out sheet is bonded to each other, and all close out sheet are total to
A planar structure or cone structure are formed with split；Both ends of two first sections being bonded to each other respectively with connection sheet are consolidated
Fixed connection.
Further, the inner side of first section to V-shape structure of above-mentioned close out sheet extends and is bent to form second section,
Second section is bonded to each other with adjacent connection sheet.
Further, be provided with detent projection in first section of above-mentioned close out sheet, close out sheet another first
The groove corresponding with detent projection is provided with branch section；Two adjacent first sections pass through respective detent projection or groove
It is mutually twisted.
Further, two first Duan Shangjun of above-mentioned close out sheet are staggeredly equipped with detent projection and groove, adjacent
Two first sections are mutually twisted on binding face by respective detent projection and groove.
Further, the common split of all close out sheet forms the cone structure that a cone angle is more than or equal to 120 degree.
Further, the common split of all close out sheet forms the cone structure that a cone angle is 160 degree.
Further, detent projection or groove are provided with second section of above-mentioned close out sheet, are set in the connection sheet
It is equipped with the groove corresponding with second section or detent projection；Adjacent connection sheet and second section are on adhesive piece by each
From detent projection or groove be mutually twisted.
Further, detent projection is provided with second section of above-mentioned close out sheet or in connection sheet, the dentation is convex
Rise on second binding face between section and connection sheet.
Further, detent projection and groove are staggeredly equipped with second section of above-mentioned close out sheet, in the connection sheet
It is provided with the groove corresponding with second section and detent projection；Adjacent connection sheet and second section are on binding face by each
From detent projection and groove be mutually twisted.
Further, the quantity of above-mentioned close out sheet is 3 or 4.
The beneficial effects of the present invention are：
1st, soft tissue set of the present invention cuts stapler as closing banding, is connected with each other and formed by multiple close out sheet and connection sheet,
Structure very simple.
2nd, soft tissue set of the present invention, which cuts stapler, can use the Ni-based marmem sheet material of titanium or tubing cutting processing system
Into i.e. usable through memory processing, process for machining and manufacturing is simple.
3rd, effect is cut in order to strengthen set, soft tissue set of the present invention cuts stapler and employs three-level anti-drop device：
The first order is connection sheet, and there is hyperelastic shape memory alloy material to be made when using higher than memory temperature for it,
The memory temperature of setting material is less than body temperature, and when soft tissue set, which cuts stapler, to be entered in human body, material shows super-elasticity, to
Contract, persistently tissue is pressurizeed；
The second level is the close out sheet at the sensing center connected as one by connection sheet, and the head of close out sheet can be pierced into tissue
Portion, prevent set from cutting stapler and coming off；
The third level is to extend be bent to form second in first section of V-shape structure in close out sheet and by first section
Branch section, adjacent first section are bonded to each other, and adjacent second section is also bonded to each other with connection sheet, so as to which comprehensive clamping is soft
Tissue.In addition, can arrange the detent projection being engaged each other and/or groove on all binding faces, further improve soft
Tissue set cuts occlusion ability of the stapler to soft tissue.
4th, the dual-use function of excision and engaging tissue in a organized way of the invention.
5th, surgical procedure of the present invention is simple.The present invention is used to use to cardioid closed mode during hemorrhoid removal, by soft tissue
Set is cut stapler and is clipped on mucous membrane, thoroughly blocks the blood circulation in haemorrhoids, makes nipped necrosis, postnecrotic wound
Healing.Soft tissue set cuts stapler Automatic-falling, does not stay foreign matter in vivo after being organized in necrosis.
6th, soft tissue set, which cuts stapler, can be shaped to 120-180 degree, be cut soft tissue set using special Technology for Heating Processing
Stapler processing be with superelastic properties, according to use demand clinically, by external force by soft tissue set cut stapler from
Center struts, and it is enclosed on the column type release head of release device.Because hyperelastic effect, soft tissue set cut kiss after release
Clutch is restored to the state before strutting and gripping tissue.
7th, because the different of clinic require, soft tissue set, which cuts stapler, includes positive installation and reversely installation when strutting,
Its characteristic is：Soft tissue set is cut into stapler using special clamping device to strut from center, engagement teeth directional is included on the inside of band
Release direction, lateral base direction outside band.As the concave surface of 120-180 degree will be shaped to when preparing to strut towards release direction,
It is then reversely installation, now discharges, then soft tissue set cuts stapler spring back angle more than 90 degree；As that will be shaped to when preparing and strutting
Then install, now discharge, then soft tissue set cuts stapler spring back angle for forward direction backwards to release direction in the concave surface of 120-180 degree
Less than 90 degree.
8th, soft tissue set cutter otch within the time of design of the present invention is organized in anastomosis clamp Automatic-falling after hyperplasia healing.
9th, the present invention is non-invasive operating theater instruments.
