Description
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.Current single-hole laparoscopic surgery due to operating difficulty comparatively large, 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 needs according to different patient size, different operating difficulties and range of operation adjusting sleeve pipe platform size and adapts to dissimilar special operational apparatus.When patient size's slight of stature, operation technique is simple and range of operation is little, only need less abdominal incision and sleeve pipe platform, insert 2-3 and prop up apparatus and get final product complete operation; Larger patient size, when operation technique is complicated and range of operation is wider, need to set up larger sleeve pipe platform, use 4-5 to prop up apparatus simultaneously, the distance set up between larger abdominal part passage and increase operating apparatus effectively can avoid the collision between apparatus, could complete operation smoothly.When the single-hole laparoscopic surgery operation of some complexity, need to use special apparatus to complete, such as the apparatus of bending kenel, it cannot pass through hard sleeve, and flexible sleeve is then applicable to the apparatus turnover of all kinds of bending kenel very much.
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 the area of operating table surface according to the operational requirements of difference operation, change the distance between stretching adjacent one-way valve, increase work angle and the range of activity of apparatus, prevent operating theater instruments in the crowded collision of table top by the area of table top; The present invention, at the diameter expanding radial drawing channel while operating table surface, retract otch, increase channel, increases the activity space of apparatus in passage, avoids the too small apparatus that causes of the diameter because of channel to intersect 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, and the corrugated surface of operating table surface is provided with check valve; Described connecting ring inside is provided with hard ring, and hard ring is for providing fixing periphery when the unidirectional snap-in structure of dicyclo is used for radial drawing; Described channel is used for retracting abdominal incision, provides operating walk way, 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.
Be provided with the hard ring of two 3/4ths circumference in connecting ring, 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 to fill in from abdominal incision, channel length presets the thickness being about human body stomach wall, lower loop enters intraperitoneal rear flank and automatically recovers circle and be close to inside abdominal cavity, channel bottom is smooth to be close to incision tissue, and channel upper end fold and incision tissue fit.Radial both sides pull connecting ring, relative two lateral movements of the hard ring in connecting ring, and the afterbody at hard ring two ends is provided with unidirectional sawtooth, when be stretched to require diameter time two unidirectional sawtooth of hard ring be fixed.Now by pulling connecting ring, the area of operating table surface increases, distance between adjacent one-way valve increases, the work angle of apparatus increases.When pulling connecting ring in radial both sides, the channel wrinkled portion be attached thereto is simultaneously by radial drawing, and increase the diameter of operating walk way in channel, after stretching, connecting ring presses in abdominal incision skin surface simultaneously, maintains otch and retracts and air-tightness.
Beneficial effect: relative to scheme of the prior art, advantage of the present invention is:
Flexible sleeve of the present invention can change the area of operating table surface according to the operational requirements of difference operation, the distance between stretching adjacent one-way valve is changed by the area of table top, increase work angle and the range of activity of apparatus, prevent operating theater instruments in the crowded collision of table top; The present invention, at the diameter expanding radial drawing channel while operating table surface, retract otch, increase channel, increases the activity space of apparatus in passage, avoids the too small apparatus that causes of the diameter because of channel to intersect phenomenon of fighting.
