Description

The adjustable single-hole laparoscopic surgery flexible sleeve of a kind of operating surface diameter
Technical field
The present invention is the adjustable single-hole laparoscopic surgery flexible sleeve of a kind of operating surface diameter, belongs to technical field of medical instruments.
Background technology
Along with the development of micro-wound surgical operation, single-hole laparoscopic surgery has become stomach wall without the new study hotspot of cicatrix field of surgery.Single-hole laparoscopic surgery is because operating difficulty is larger at present, and clinical practice is still in the primary stage, and first its reason shows the restriction of single-incision laparoscope sleeve platform.Desirable single-incision laparoscope sleeve need to and adapt to dissimilar special operational apparatus according to different patient's builds, different operating difficulty and range of operation adjusting sleeve pipe platform size.In the situation that patient's build is modest, operation technique is simple and range of operation is little, only need less abdominal incision and sleeve pipe platform, insertion 2-3 props up apparatus and gets final product complete operation; Larger at patient's build, when operation technique complexity and range of operation are wider, need to set up larger sleeve pipe platform, use 4-5 to prop up apparatus simultaneously, the distance of setting up larger abdominal part passage and increasing between operating apparatus can effectively be avoided the collision between apparatus, could complete smoothly operation.When the operation of some complicated single-hole laparoscopic surgeries, need to use special apparatus to complete, the apparatus of crooked kenel for example, it cannot pass through hard sleeve, and the apparatus that flexible sleeve is applicable to all kinds of crooked kenels very much passes in and out.
Summary of the invention
Technical problem: the object of the invention is to provide a kind of operating surface diameter adjustable single-hole laparoscopic surgery flexible sleeve.The present invention can change according to the operational requirements of difference operation the area of operating table surface, by the distance between the area change stretching adjacent one-way valve of table top, increases work angle and the range of activity of apparatus, prevents that operating theater instruments is in the crowded collision of table top; The present invention when expanding operating table surface radial drawing channel, retract otch, increase the diameter of channel, increase the activity space of apparatus in passage, avoid the too small apparatus that causes of diameter because of channel to intersect the phenomenon of fighting.
Technical scheme: in order to solve these problems of the prior art, the invention provides the adjustable single-hole laparoscopic surgery flexible sleeve of a kind of operating surface diameter, the top of this flexible sleeve is operating table surface, and centre is channel, bottom is lower loop, and operating table surface is connected by connecting ring with channel; Described operating table surface is corrugated, on the corrugated surface of operating table surface, is provided with check valve; Described connecting ring inside is provided with hard ring, and hard ring provides fixedly periphery while being used for radial drawing for the unidirectional snap-in structure of dicyclo; Described channel is used for retracting abdominal incision, and operating walk way is provided, and channel top is ripple fold shape, and bottom is smooth shape; Described lower loop is used for providing intraperitoneal supporting surface, and its inside is provided with wire loop.
Operating table surface, connecting ring, channel, lower loop are that integral molded plastic forms, and material is silica gel, and each several part joint face is and flexibly connects.
In connecting ring, be provided with the hard ring of two 3/4ths circumference, the afterbody at hard ring two ends is provided with sawtooth, and two rings can lock after unidirectional radial drawing.
Described hard ring material is polyethylene.
Lower loop inside is provided with wire loop.
When the present invention uses, lower loop is pinched and flatly from abdominal incision, filled in, the default thickness that is about human body stomach wall of channel length, lower loop enters intraperitoneal rear flank and automatically recovers circle and be close to abdominal cavity inner side, channel bottom is smooth to be close to incision tissue, channel upper end fold and incision tissue's laminating.Radially both sides pull connecting ring, and the hard ring in connecting ring is relatively to two lateral movements, and the afterbody at hard ring two ends is provided with unidirectional sawtooth, when being stretched to two unidirectional sawtooth of hard ring while requiring diameter, are fixed.Now, by pulling connecting ring, the distance between the increase of the area of operating table surface, adjacent one-way valve increases, the work angle of apparatus increases.Simultaneously, when radially both sides pull connecting ring, the channel gauffer part being attached thereto, simultaneously by radial drawing, has increased the diameter of operating walk way in channel, and after stretching, connecting ring presses in abdominal incision skin surface, maintains that otch retracts and air-tightness.
Beneficial effect: with respect to scheme of the prior art, advantage of the present invention is:
Flexible sleeve of the present invention can change according to the operational requirements of difference operation the area of operating table surface, area by table top changes the distance between stretching adjacent one-way valve, increased work angle and the range of activity of apparatus, prevented that operating theater instruments is in the crowded collision of table top; The present invention when expanding operating table surface radial drawing channel, retract otch, increase the diameter of channel, increase the activity space of apparatus in passage, avoid the too small apparatus that causes of diameter because of channel to intersect the phenomenon of fighting.
