Description
Technical field
The present invention relates to a kind of swing locating mechanism for selectivity cutting tissue direction and location tractor, belong to and medical treatment
Technique with the apparatus field.
Background technology
Arc-shaped cutting anastomat is more and more extensive for the application of distal rectal selectivity cutting tissue.But traditional arc cutting
Anastomat uses purse wire glass tube down-drawing in the middle of operation, i.e. will intend the tissue of excision to the direction being parallel to anal canal with purse wire
Tractive outside anus.But doctor is when carrying out tractive to purse wire to the tissue intending excision, special due to distal rectal
Anatomy relationship, the rectal mucosa of the nearlyest anus is more relatively fixed, and away from the mucosa relative relaxation of anus, therefore create lotus
Envelope curve is in the uneven problem of the cutting tissue up and down of fixing line, and the fixing cut tissue of line epimere is more, and distal resection
Organize less, cannot realize during purse wire pulling operation outside anus, lead the tissue intending excision to the direction being parallel to anal canal
Draw, cause doctor to be difficult in operation accurately and select to excise position, even can not excise for tumor patient swollen completely
Tumor, it is impossible to reach to effect a radical cure purpose.Moreover owing to purse wire traction process being by operating forceps tractive, not only need personnel
Auxiliary operation, when tiing a knot, is not easy to tighten purse wire, and the operating time is longer.
Summary of the invention
It is an object of the invention to provide a kind of rational in infrastructure, can facilitate purse wire is introduced and knotting operation be used for selectivity
The swing locating mechanism of cutting tissue direction and location tractor.
The present invention is that the technical scheme reaching above-mentioned purpose is: a kind of for selectivity cutting tissue direction and location tractor
Swing locating mechanism, it is characterised in that: include swinging location bar, swing the lotus that location bar includes that base plate and biside plate are formed
The vertical passage that envelope curve passes through, the front end swinging location bar is provided with for purse wire carries out spacing at least two front
Groove, rear end are provided with at least two for supporting the rear wire casing of purse wire.
Wherein: described swing flat board or the arc of flaring that bar front portion, location is flaring, and flat board or the end of arc
Portion is provided with 2～10 front wire casings.
The described each front wire casing swinging location bar also has guide purse wire and the pincers of cross spacing in notch front portion
Mouthful, jaw both sides are staggered along short transverse and are provided with the block extending into notch, and jaw both sides are additionally provided with and each block phase
To breach, and notch top by chamfered transition in vertical passage.
Described swing location bar rear portion be provided with end plate, end plate be provided with 2～4 after wire casing, each rear wire casing is upper
Portion is provided with backstop.
The described base plate swinging location bar is provided with at least one junction pole in vertical passage, and swings the biside plate of location bar
Top is provided with middle thread block at junction pole.
The described location bar that swings is provided with distributor plate at base plate at vertical passage rear portion, and the biside plate swinging bar rear portion, location is provided with
Rear thread block.
The described biside plate swinging location bar is hinged in the U-lag of bearing, and bearing is provided with for propping up at the bottom land of U-lag
Hold the swing seat swinging location bar, and the biside plate swinging location bar is carried out spacing by the groove sidewall of the U-lag of bearing.
Being provided with at least two along short transverse outside described at least one side plate swinging location bar and swing locating slot, bearing exists
The groove inside sidewalls of U-lag is correspondingly provided with swing positioning convex.
Swing seat on described bearing is made up of the contrary front bevel of incline direction and back bevel, and front bevel and the company of back bevel
The supporting projection supporting meeting place swings location bar.
The location bar that swings of the present invention is provided with the vertical passage that purse wire passes through, and front end is provided with for carrying out purse wire
Wire casing before spacing at least two, at least two is for supporting the rear wire casing of purse wire in its back-end, therefore can be according to patient
The position of pathological tissues, the position of regulation purse wire, and by the purse wire determined from anterior front wire casing carry out spacing after
Moved to the rear wire casing at rear portion by vertical passage, make purse wire that the tissue intending excision is led position by swinging location bar
Operation, and after swinging location bar under the supporting of wire casing, conveniently purse wire is carried out knotting fixing, therefore can be accurate by purse wire
Really organizing plan excision to the direction tractive outside anus being parallel to anal canal, changes traditional direction of draw, makes purse wire
Lead and anal canal, rectal wall form vertical angle, it is ensured that towing point is exactly the center intending resection organization, permissible
Making doctor accurately excise selected tissue easily, doctor is easy to operate, and operation rapidly, makes operation technique more
Add safety, save manpower, material resources, improve procedure efficiency.Swing location bar is hinged on bearing by the present invention, therefore leads to
Crossing the swing seat on bearing makes swing location bar along longitudinally realizing swing, positions the vertical of bar when purse wire is introduced to swing
In passage, swing location bar can be made to swing at swing seat, make bar front portion, swing location tilt, more convenient to intending excision group
Knit to the direction tractive outside anus being parallel to anal canal.
