Abstract
A kind of adjustable-pressure laparoscopic cannula, the sleeve pipe includes airway and the cavity of airway upper end, the side of cavity is provided with a gas interface, a two-way gas interface valve is provided with gas interface, airway periphery to gas interface position is provided with an adjustable inflatable capsule, and the adjustable inflatable capsule connects with two-way gas interface valve simultaneously.It can be inflated respectively to abdominal cavity or adjustable inflatable capsule by gas interface valve.The utility model can solve art middle sleeve and deviate from accidentally, reduce operating difficulty and risk, and can adjusting sleeve pipe position at any time, facilitate operation technique, effectively solve simultaneously in art and postoperative wound bleeding problems, can exempt doctor's trouble and worry, shorten operating time, corrective surgery risk is reduced, mitigates corrective surgery pain.The device is simple to operate, easy to spread, and cheap, and potential applicability in clinical practice is extensive.
Description
Technical field
The utility model belongs to medical auxiliary apparatus technical field.
Background technology
Laparoscopic surgery is the Minimally Invasive Surgery that a new development is got up, and is the inexorable trend of following operation development.By it
The characteristics of surgical wound is small, damaging surrounding tissue is low, postoperative tissue adhesion is light, postoperative pain is light, the hospital stays is short, by vast trouble
Person is received.Laparoscopic cannula is placed in human body as the passage of operating theater instruments at present, and fixation can not be bonded with stomach wall, it is easy to
Swing or abjection is external；Fixed sleeving insertion depth can not be adjusted in art, increases patient's operation difficulty and operation risk；Cover simultaneously
The easy bleeding of pipe puncture, patient need to find blutpunkte hemostasis, extend operating time, increase postoperative hemorrhage risk.
Utility model content
The utility model purpose, which is to provide one kind, can avoid laparoscopic cannula from swinging and deviate from vitro, can arbitrarily adjust simultaneously
Fixed sleeving insertion depth, and stomach wall supporting ＆ stablizing, and can effectively prevent the laparoscopic surgery sleeve pipe of wound bleeding.
Technical solutions of the utility model
A kind of adjustable-pressure laparoscopic cannula, cavity of the sleeve pipe including airway and airway upper end, the one of cavity
Side is provided with a gas interface, and rotating bidirectional gas interface valve, airway periphery to gas are provided with gas interface
Interface position is provided with an adjustable inflatable capsule, and the adjustable inflatable capsule communicates with gas interface valve simultaneously.
The airway upper end is provided with a circumferential support arm simultaneously with cavity connecting portion periphery.Gas interface valve
On be provided with a pressure adjustment button.Airway lower end is provided with one and can be vented to the side of the intraperitoneal inflation in sleeve pipe side simultaneously
Hole, the side exhaust outlet are not communicated with air bag.
The advantages of the utility model and good effect：
The utility model can reduce patient's operation difficulty, according to concrete condition adjusting sleeve pipe insertion depth in art, prevent from covering
Pipe is swung, and is shortened operating time, is reduced postoperative wound bleeding risk.
The utility model can solve the problems, such as that art middle sleeve is deviate from accidentally, can reduce patient's operation difficulty, and can be according to art
Middle concrete condition adjusting sleeve pipe insertion depth and position at any time, prevent sleeve pipe from swinging, facilitate operation technique, while can effectively subtract
Few postoperative wound bleeding risk, can exempt doctor's trouble and worry, shorten operating time, reduce corrective surgery risk, mitigate patient
Operation pain.
The device is simple to operate, easy to spread, and cheap, and potential applicability in clinical practice is extensive.
Brief description of the drawings
Fig. 1 is adjustable-pressure laparoscopic cannula schematic diagram.
In figure, 1 gas interface, 2 rotating bidirectional gas interface valves, 3 pressure adjustment buttons, 4 airways, 5 support arms,
6 adjustable inflatable capsules, 7 side steam vents, 8 cavitys.
Embodiment
Embodiment 1：
As illustrated, adjustable-pressure laparoscopic cannula provided by the utility model, including airway 4 and airway upper end
Cavity 8, the side of cavity is provided with a gas interface 1, a rotating bidirectional gas interface is provided with gas interface
Valve 2, a pressure adjustment button 3 is provided with the two-way gas interface valve.Airway periphery to gas interface position is set
An adjustable inflatable capsule 6 is equipped with, the adjustable inflatable capsule connects with two-way gas interface valve 2 simultaneously.
The airway upper end is provided with a circumferential support arm 5 simultaneously with cavity position periphery.Airway lower end is simultaneously
A side steam vent 7 is provided with, can be not communicated with to the intraperitoneal inflation in sleeve pipe side, the side exhaust outlet with air bag.
When the long-armed and gas interface of the two-way gas interface valve 2 is parallel, gas interface 1, the and of cavity 8 can be passed through
Airway 4 is to intraperitoneal inflation；When long-armed downward, it can be inflated to adjustable inflatable capsule 6.I.e. two-way gas interface valve can
To be inflated respectively to abdominal cavity or adjustable inflatable capsule, sleeve pipe insertion is inflated behind abdominal cavity to air bag, it is ensured that sleeve pipe and stomach wall
Fixation, avoid accidentally deviating from art；Wound can be oppressed, prevent bleeding simultaneously；Sleeve position need to be such as adjusted in art, can be led to
Cross press pressure regulation button 3 and adjust gasbag pressure at any time, to change the depth of sleeve pipe and angle.
Support arm 5 can make collar supports stomach wall, and retaining sleeve is stable, prevent art middle sleeve wobble effects from operating.
