Detailed Description
As shown in fig. 1, in order to provide a schematic structural diagram of the medical endoscope visual field expanding device of the present invention, as can be seen from fig. 1, the medical endoscope visual field expanding device of the present invention includes: an outer poling 1 with a tip at one end; a guide tube 3 passing through the outer through tube; an airbag 2 disposed at one end of the guide tube; an inflation tube 4 partially penetrating the guide tube and having one end connected with the air bag and the other end connected with an air supply device 6 (the existing medical air supply device can be adopted); and a gas detecting element 5 disposed on the gas filling pipe for detecting the flow rate of the gas.
In order to dial the ovary in the time of can not damaged when laparoscopic surgery to fully expose the field of vision when laparoscopic surgery, thereby improve the operation success rate, reduce the potential risk to the patient, the utility model discloses medical endoscope field of vision extension device adopts the structure of settling guide tube and gasbag in the outer poling.
Specifically, the utility model discloses medical endoscope field of vision extension device includes hollow outer poling 1, as shown in fig. 1, and the one end (being the front end) of outer poling has the pointed end, promptly, and outer poling front end processing has the inclined plane to outer poling front end can pass the handle hole that laparoscopic surgery seted up smoothly and enter into the patient abdominal cavity.
A hollow guide pipe 3 is arranged in the outer penetrating pipe 1 in a penetrating way, the length of the guide pipe 3 is equal to or slightly greater than that of the outer penetrating pipe, and the outer diameter of the guide pipe is equal to or slightly smaller than the inner diameter of the outer penetrating pipe. The front end of the outer penetrating pipe can be in threaded connection (not shown) or tight fit with the front end of the guide pipe.
At one end of the guiding tube 3 (i.e. the front end for insertion into the abdominal cavity) is arranged a balloon 2 (as shown in fig. 4) which is inflated to push open or poke open the ovarian tissue in the abdominal cavity, the outer wall of the balloon being in direct or indirect contact with the inner wall of the guiding tube. The ovary and the nearby tissues in the abdominal cavity are jacked open by the inflated air bag, and the condition that the ovary is damaged by using rigid forceps to grab the ovary in the prior art is avoided.
When the air bag is arranged, the outer wall of the air bag can be directly fixed on the inner wall of the guide pipe in a bonding mode; alternatively, a sleeve 8 (as shown in fig. 9) may be provided outside the balloon, the outer wall of the balloon may be fixed to the inner wall of the sleeve by means of adhesion or the like, and the outer wall of the sleeve may be fixed to one end of the inner wall of the guide tube by means of screw-thread connection or interference fit with the guide tube.
The air inlet of gasbag sets up in gasbag one side center department to, can set up rather than fixed connection's joint 21 in gasbag air inlet department, and connect and be connected with the gas outlet of gas tube 4, during the connection, connect and gas tube can be for dismantling the connection, like accessible threaded connection or grafting, also can be for undetachable connection, like bonding.
