Abstract
The invention provides a single-port laparoscope choledochoscope sheath tube, which is characterized in that: the single-channel hard tube comprises a body part, wherein the upper end of the body part is connected with a head part, and the lower end of the body part is connected with a tail part; the head part is a hose, and the front end of the head part is conical; the tail inner tube cavity is a flexible tube, and two ends of the tail inner tube cavity are provided with annular valves. Has the advantages of good supporting effect on the choledochoscope, damage prevention on the choledochoscope and the like.
Description
Technical Field
The invention relates to a laparoscope sheath tube, in particular to a single-hole laparoscope cholangioscope sheath tube.
Background
The gallbladder is an important digestive organ of a human body, and is generated along with attention and protection of the function of the gallbladder and the inoculation of gallbladder-protecting stone-taking operation. The operation mode gradually changes from the traditional small incision gallbladder-protecting operation of the right upper abdomen to the existing full laparoscopic gallbladder-protecting operation of the right upper abdomen after the gallbladder-protecting operation of the laparoscopic assisted small incision. The gallbladder of the complete laparoscope is protected by adopting three-hole or double-hole channels, the laparoscope enters the abdominal cavity through the navel poking and clamping channel, and the choledochoscope enters the abdominal cavity through the right upper abdomen poking and clamping channel. Under the direct vision of the laparoscope, an operator holds the choledochoscope with the left hand, the choledochoscope enters the gallbladder at the shortest distance by adjusting the poking direction of the right upper abdomen, and the right hand operates accessories such as a stone-taking basket and the like to perform operations such as stone-taking, polyp excision, Luo-Ashi sinus incision and the like.
With the increasing requirements of people on minimally invasive technologies, the single-port laparoscopic technology is gradually applied to clinic, wherein the cholecystectomy of the single-port laparoscopic is most widely performed, but the development of the cholecystectomy of the single-port laparoscopic is slower. Mainly because the navel incision is far away from the gall-bladder, and the choledochoscope is a soft lens, the choledochoscope enters the gall-bladder for a long time due to the fact that the support of the choledochoscope body is lacked in the process of being placed in the navel channel, and the visual field of the choledochoscope is difficult to fix in the gall-bladder, so that observation and treatment of the choledochoscope are difficult.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a sheath tube of a choledochoscope of a single-port laparoscope.
The technical scheme of the invention is that the single-port laparoscope choledochoscope sheath tube is characterized in that: the single-channel hard tube comprises a body part, wherein the upper end of the body part is connected with a head part, and the lower end of the body part is connected with a tail part;
the head part is a hose, and the front end of the head part is conical;
the tail inner tube cavity is a flexible tube, and two ends of the tail inner tube cavity are provided with annular valves.
The body part has an outer diameter of 1cm or 0.5cm and a length of 40 cm.
Compared with the prior art, the invention has the following advantages:
1. the single-port laparoscope gallbladder-protecting operation of the laparoscope and the choledochoscope is realized;
2. the body part is a hard tube, so that the choledochoscope has good supporting effect and can more easily enter the gallbladder;
3. the head end is a hose which has a protection effect on the choledochoscope body and avoids the damage of the drainage tube wall to the choledochoscope body;
4. the head end is a hose which can be bent properly and can be bent along with the bending of the choledochoscope body, so that the choledochoscope is prevented from being damaged by the angulation and folding of the abdominal cavity section and the protective sleeve of the choledochoscope;
4. a double-layer annular valve is arranged to prevent the air leakage of the abdominal cavity;
5. the head end is conical, and can easily enter the gallbladder cavity through the gallbladder incision.
Drawings
FIG. 1 is a schematic of the present invention.
In the figure: 1. head, 2, body, 3, tail, 4, annular valve.
Detailed Description
The embodiments are described below with reference to the accompanying drawings:
the body part 2 is a single-channel hard plastic pipe, the outer diameter of the pipe cavity is 1cm or 0.5cm, the inner diameter is 0.8 or 0.4cm, and the length is 40 cm; the tail part 3 is 1cm long and made of soft silica gel or resin material, and two ends are provided with annular valves 4; the head part 1 is a cone-shaped hose made of resin or silica gel.
When in use, the invention is placed in the abdominal cavity through the single-port laparoscope device, placed near the incision of the gall bladder or enters the gall bladder cavity under the monitoring of the laparoscope, and then is placed in the choledochoscope through the device, the choledochoscope penetrates out of the device and can easily enter the gall bladder to carry out operations such as observation, incision, stone removal and the like in the gall bladder cavity.
