Description
Technical field
The present invention relates to a kind of sheath pipe, especially relate to a kind of peritoneoscope sheath pipe, belong to Design for Medical Device manufacturing technology field.
Background technology
At present the most clinically laparoscopic technique because of its Wicresoft, effectively and the swiftest and the most violent the promoting at situation of all-level hospitals of advantage such as postoperative wound is attractive in appearance
Application, but this technology needs to inject gas formation pneumoperitoneum toward intraperitoneal.The trocar that the i.e. this area of stomach wall channel sheath pipe is commonly called as at present
Can realize pipe by built-in unidirectional catch and silica gel ring interior air tight, but between sheath pipe body lateral surface and sufferer mural tunnel
Leakage problem, and sheath pipe exits the problem of sufferer abdominal wound the most in operation and the most effectively solved.
Prior art occurring, the solution being similar to has following several: a kind of Application No. being Han Wenjun and designing
The air-leakage preventing device of 200920281737.X, this air-leakage preventing device is mainly made up of silica gel sheath and silicon rubber cup pad, described silica gel sheath
Be arranged on the caudal part outside trocar body with silicon rubber cup pad, it is achieved need during anti-gas-leak effect to force by the part of silica gel sheath with
Body inserts subcutaneous 1-2, is then fastened on skin of abdomen by silicon rubber cup pad.Its shortcoming is on the one hand to be clamp-oned by silica gel sheath
Subcutaneous meeting is relatively elaborate, and the spilling gas it may be caused cannot to realize and the fitting tightly of skin of accumulation under silicon rubber cup pad；
On the other hand postoperative skin wounds can by silica gel sheath expand bigger, affect attractive in appearance.The application number of another kind of Shi Qinwei army design
For the air-leakage preventing device of 200620078426.X, this device is that nearly middle section position arranges an air bag outside trocar body, to the greatest extent
Pipe can realize anti-gas-leak and the effect of fixing trocar body really, but it is known that trocar body inserts sufferer
Need during body wall outer surface try one's best smooth just be easier to insert, the airbag design exceeding body certainly will hinder trocar body
Inserting smoothly, the postoperative trocar of extracting also can have difficulties.Also having a kind of is the front Application No. designed of victory
The air-leakage preventing device of 201320344949.4, this device yet suffer from when spill accumulated gases under sealing plate time, there is also sealing
Plate is difficult to the problem realizing closely being attached on skin, causes sealing unsuccessfully.
Summary of the invention
The technical problem to be solved is: provides a kind of easy to operate, simple in construction, can preferably rise during use
Peritoneoscope sheath pipe to sealing function.
A kind of peritoneoscope sheath pipe is the technical scheme is that, including sheath tube body, described abdominal cavity by solving above-mentioned technical problem
Mirror sheath pipe also includes the anti-leak collar containing tractor, and the lateral wall in the middle part of described sheath tube body is provided with circumferentially
Mounting groove, described anti-leaking cover ring is arranged in described mounting groove；The institute sufferer abdominal cavity is inserted from sufferer abdominal wound
State peritoneoscope sheath pipe, axially remove described peace by the anti-leak collar described in described tractor traction along described sheath tube body
After tankage, close the gap between described peritoneoscope sheath pipe and sufferer abdominal wound.
Further, the longitudinal center line of described mounting groove cross section radially and described sheath tube body is the folder of 40～50 °
Angle, described sheath tube body have one for the front end inserting sufferer abdominal wound, the described anti-leak collar is by described installation
On the lateral wall being arranged on described sheath tube body that groove tilts, described tractor and anti-the letting out near side, described sheath tube body front end
The leakage collar connects.
Such scheme it is preferable that, described mounting groove is vertically in the groove structure being projected as rounding off of vertical, institute
State the anti-leak collar groove structure with described rounding off that projects in its cross section to adapt.
Further, described tractor is made up of a medical pulling rope, and described pharmaceutical pulling rope passes through one end and institute
The anti-leak collar stated connects.
Further, the described anti-leak collar is made up of medical silica-gel.
Further, described sheath tube body for the front end inserting sufferer abdominal wound have with described sheath tube body axially in
Heart line is the inclined plane of 40～50 ° of angles.
The invention has the beneficial effects as follows: by being provided with mounting groove circumferentially on the lateral wall in the middle part of described sheath tube body,
Then the anti-leak collar sealed is installed in described mounting groove, and in use, makes to create from sufferer abdominal part
Mouth inserts the described peritoneoscope sheath pipe in sufferer abdominal cavity, by the anti-leak collar described in described tractor traction along described sheath pipe
After body axially removes described mounting groove, close the gap between described peritoneoscope sheath pipe and sufferer abdominal wound.So, by
Being arranged in described mounting groove in the described anti-leak collar, its part protruding sheath tube body lateral wall is relatively fewer, it is ensured that
The convenience of update, after described peritoneoscope sheath pipe inserts in sufferer abdominal cavity, then described in being drawn by described tractor
After the anti-leak collar axially removes described mounting groove along described sheath tube body, close described peritoneoscope sheath pipe and sufferer abdominal wound
Between gap, it is ensured that can preferably play anti-gas-leak effect during use.Simultaneously as described peritoneoscope sheath pipe is only
Including sheath tube body and the anti-leak collar being arranged in the mounting groove of described sheath tube body lateral wall, thereby may be ensured that described abdomen
The structure of chamber mirror sheath pipe becomes very simple, reaches effectively to reduce the purpose of production cost.
