Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of sacculus and wears
Thorn device.
Background technology
At present, known perforator is that one pierces through stomach wall and provides for other operating theater instruments
Enter the operating theater instruments of lumenal passageway, belong to a kind of Minimally Invasive Surgery apparatus.In prior art,
Perforator is single hole straight tube structure, is easily generated swing during use, seriously can be from human body
Upper abjection, is delayed in operation process and affects operation progress because perforator slips, increase the weight of
The wound of surgical patient, has delayed the rehabilitation of patient.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have carried
Go out solution miscellaneous.Such as, Chinese patent literature discloses a kind of dribbling
The perforator [application number: 201520312345.0] that capsule is fixing, including puncture casing with wear
The puncturing lever being located in puncture casing, puncture casing includes tubular hard sleeve body,
Hard sleeve body one end is provided with the casing seat passed for puncturing lever, and hard sleeve body week is outwards
Side offers at least one guiding gutter, is arranged with by soft in hard sleeve body outer circumferential
Material is made and can be closed by the notch of guiding gutter thus forms the soft overlay film of flow-guiding channel
Body, and flow-guiding channel one end is connected with the check valve being arranged on hard sleeve body one end,
The other end be positioned at hard sleeve body other end outer circumferential and by soft overlay film body end
The annular balloon peripherally and outwardly convexed to form is connected.Although such scheme is to a certain degree
On solve the problem that existing perforator easily swings, but the program still also exists: right
Sacculus is inflated or soft overlay film body easily sticks out during topping up, hinders sacculus
Inflation, thus cause the fixing problem such as the most firm, easy to fall off.
Summary of the invention
