A kind of disposable celiac mirror hand-actuated accelerator, clutch and brake
Technical field
The present invention relates to medical apparatus and instruments, be directly involved in the hand-actuated accelerator, clutch and brake for disposable celiac videoendoscopic surgery.
Background technology
Hands helps disposable celiac mirror surgery (hand-assisted laparoscopic surgery, HALS) technology is a kind of novel Minimally Invasive Surgery mode grown up the mid-90 in 20th century, be under maintenance pneumoperitoneum, allow surgeon hands to be entered abdominal cavity and assist disposable celiac mirror apparatus to complete more complicated operation technique.It makes disposable celiac mirror less invasive techniques and traditional abdominal combine to greatest extent, makes patient with wound healing disease little as far as possible.
Hands helps disposable celiac mirror surgical operation to be that disposable celiac mirror hand-actuated accelerator, clutch and brake is inserted abdominal cavity by the cut out portion of well in advance, patient's non-dominant hand wears sterile gloves, coating liquid paraffin, stretch into abdominal cavity through hand-actuated accelerator, clutch and brake collar extension, close collar extension, the airtight passage in arm turnover abdominal cavity can be set up.Current hand-actuated accelerator, clutch and brake uses Shi doctor's arm limited more at intraperitoneal, arbitrarily can not rotate, otherwise can affect the sealing in abdominal cavity, and prolonged operations Shi doctor arm there will be the uncomfortable situations such as numb, causes operation risk to increase.
Summary of the invention
In order to solve the problem, the invention provides a kind of disposable celiac mirror hand-actuated accelerator, clutch and brake, surgeon can be made suitably to adjust arm, the sealing of peritoneoscope hand-actuated accelerator, clutch and brake when can ensure to perform the operation, avoid the phenomenon that disease of hand discomfort occurs during surgeon's prolonged operations, reduce operation risk.
Technical scheme of the present invention is: disposable celiac mirror hand-actuated accelerator, clutch and brake, comprise dilator (1) and connecting device (3), described dilator (1) upper end fixed connection apparatus (3), dilator (1) comprises and struts ring and junctional membrane (5), its lower end of dilator is provided with down and struts ring (4), connecting device (3) and under strut between ring (4) and form tubular structure by junctional membrane (5); Connecting device (3) is plastics or falope ring, and the plane of connecting device (3) is provided with one deck sealing film (9), and the bottom of sealing film is provided with second layer thin film (6), and second layer thin film central authorities are wrist elasticity beam hole.
Further, dilator (1) top is provided with arm sealer, described arm sealer is connected with connecting device (3), arm sealer is made up of tubular pellosil (7) and arm band (8), arm band (8) is placed in the cohesive bandage of tubular pellosil (7) upper end, and connecting device (3) is arranged at tubular pellosil (7) lower end.
Further, described junctional membrane (5) is made up of elastic silica gel.
Beneficial effect of the present invention: a kind of disposable celiac mirror hand-actuated accelerator, clutch and brake of the present invention, it is of the present invention that the cost of material is low, its arm sealer can be made up of double-layer seal film, when doctor's prolonged operations, arm can suitably adjust, and facilitates doctor to operate, and avoid doctor's arm to there will be the situation of numbness and uncomfortableness, ensure the sealing in abdominal cavity, the carrying out of convenient operation, also can reduce operation risk.

Detailed description of the invention
Be further described below in conjunction with Fig. 1 to 3 couple of the present invention, disposable celiac mirror hand-actuated accelerator, clutch and brake, comprise the arm sealer (2) on dilator (1) and top, described dilator (1) upper end body surface part is provided with a connecting device (3), its lower end is provided with down and struts ring (4), connecting device (3) and under strut between ring (4) and form tubular structure by junctional membrane (5); Arm sealer described in top is connected with connecting device (3), arm sealer is made up of tubular pellosil (7) and arm band (8), arm band (8) is placed in the cohesive bandage of tubular pellosil (7) upper end, and connecting device (3) is arranged at tubular pellosil (7) lower end.Described junctional membrane (5) is made up of flexible silicon glued membrane.The length that junctional membrane (5) forms tubular is 2-5cm.
Connecting device (3) is plastics or falope ring, the diameter of connecting device and plastics or falope ring is 7-12cm, thickness is at 0.7-1.5mm, there is suitable elasticity, the plane of connecting device (3) is provided with one deck sealing film (9), the bottom of sealing film is provided with second layer thin film (6), and second layer thin film central authorities are wrist elasticity beam hole.Sealing film and junctional membrane (5) can adopt plastics PE, PP, PET or silica gel, rubber membrane etc.Thickness is about 0.1.
Preoperative according to kinds of Diseases design hands help otch, observation port and primary operating hole position, add auxiliary operation hole if desired.Help incision site open abdomen holostrome at the hands of design, incision length determines according to the size of patient's hands.During art, namely dilator 1 is strutted down ring (4) and junctional membrane (5) helps cut out portion to be placed in intraperitoneal by hands, connecting device (3) is plastics or falope ring laminating incision of abdominal wall, under strut the length that ring (4) can adjust junctional membrane (5) cylinder according to demand.The connecting device of dilator is connected with arm sealer, arm is put into arm sealer, arm band tightens rear breakseal film (9) according to doctor's arm, arm is stretched in the wrist elasticity beam hole of second layer thin film central authorities by connecting device (3), wrist elasticity beam hole is a hole be made up of rubber band, utilize rubber band elastic cuffs wrist of stopping to seal, carry out operation technique.Rubber band elastic cuffs wrist of stopping carries out sealing and can arbitrarily adjust, and arm band can arbitrarily adjust, and all can facilitate during doctor's art and use.
During operation, doctor's nondominant hand needs to be placed in intraperitoneal for a long time, because wrist elasticity beam hole and pellosil do not limit the motion of arm, doctor suitably can adjust arm position and can not destroy pneumoperitoneum, facilitate the adjustment of arm during surgical and avoid doctor's arm to occur the phenomenon of numbness and uncomfortableness, affect surgical effect, increase operation risk.The cost of material is low for this, is easily prepared into disposable operating theater instruments.
It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
