Abstract
Containing the perforator of silencing means, the end seal of the sheath pipe of the perforator of this utility model is containing upper cover, radial seal assembly, silencing means and lower cover; Silencing means is the elastomer that elastic deformation can occur, and one end of silencing means is arranged on radial seal assembly, other one end of silencing means be arranged on described under cover; Radial seal assembly is arranged between upper cover and lower cover.Because described radial seal assembly holds up by silencing means, reduce the gap between upper cover and the top board of radial seal assembly, avoid the strike note sent when operating theater instruments outwards withdraws.Meanwhile, when operating theater instruments is inwardly gone forward one by one, due to silencing means cushioning effect, avoid the strike note sent when operating theater instruments is inwardly gone forward one by one.Like this, operating theater instruments when moving back and forth, can not knock in perforator, achieves the object of noise reduction.
Description
Technical field
This utility model relates to a kind of laparoscopically surgical operation apparatus, particularly relates to the perforator used in laparoscopic surgery.
Background technology
Laparoscopic surgery obtains to be applied more and more widely, in order to avoid nosocomial infection, the consumption of the disposable puncture device (Trocar) used in laparoscopic surgery is also increasing, on the basis ensureing serviceability, simplify structure, reduce costs, improve performance, this trend has become the direction that perforator improves.
The carrying out of conveniently performing the operation, requires that perforator can use the operating theater instruments of 5mm, also can use 10mm, or the operating theater instruments of 12mm.Like this, the diameter of the apparatus through hole of the radial direction seal ring of perforator is less than 4mm usually.When the operating theater instruments that diameter is larger, as 10mm, or the operating theater instruments of 12mm, during operating theater instruments through hole by the radial direction seal ring of 4mm, radial direction seal ring creates larger encircles power, when operating theater instruments moves back and forth, the top board of radial seal coil assembly can clash into upper cover, or the lower platen of radial ring assemblies can clash into lower cover, knocks, form noise, interference doctor.Because the perforator of prior art exists the shortcoming that can knock when operating theater instruments moves back and forth, thus need to improve.
Summary of the invention
Containing the perforator of silencing means, described perforator 100 is made up of puncturing lever 101 and sheath pipe 102.The end seal 1 of the sheath pipe 102 of described perforator is containing upper cover 11, radial seal assembly 12, silencing means 13 and lower cover 14; Described silencing means 13 is elastomers that elastic deformation can occur, and one end of described silencing means 13 is arranged on radial seal assembly 12, and other one end of described silencing means 13 is arranged on described lower cover 14; Described radial seal assembly 12 is arranged between described upper cover 11 and described lower cover 14.
Further, described silencing means 13 is the elastomers of the thin-walled tubular structure that medical elastic material manufactures.
The elastomer of the thin-walled tubular structure of described silencing means 13 is containing at least 2 resiliency supported lower limb 13-1.
In addition, described silencing means 13 is the elastomers of the spring structure that medical elastic material manufactures.
Elastomeric silencing means 13 one end of described spring structure is arranged in the installing hole 12-0 of described radial seal assembly 12, and the other end is arranged in the installing hole 14-0 of described lower cover 14.
The core of the technical scheme of this utility model is:
Described silencing means 13 is elastomers that elastic deformation can occur, described radial seal assembly 12 is upwards held up, the top board 12-1 of described radial seal assembly 12 is contacted with the upper cover 11 of described end seal 1, or gap between described upper cover 11 and the top board 12-1 of described radial seal assembly 12 is very little, usually 0.5mm is less than, like this, when outwards withdrawing operating theater instruments 103, can not hard hit be there is between described top board 12-1 and described upper cover 11, avoid the appearance of clashing into sound.When operating theater instruments 103 is inwardly gone forward one by one, due to the cushioning effect of the described silencing means 13 that elastomer builds, avoid the lower platen 12-5 of described radial seal assembly 12 and lower cover 14 hard hit of described end seal 1, avoid the appearance of clashing into sound, thus make operating theater instruments 103 when moving back and forth, can not knock, achieve the object of noise reduction.
Containing the perforator of silencing means, the end seal 1 of the sheath pipe 102 of the perforator of this utility model is containing upper cover 11, radial seal assembly 12, silencing means 13 and lower cover 14; Described silencing means 13 is elastomers that elastic deformation can occur, and one end of described silencing means 13 is arranged on radial seal assembly 12, and other one end of described silencing means 13 is arranged on described lower cover 14; Described radial seal assembly 12 is arranged between described upper cover 11 and described lower cover 14.Because described radial seal assembly 12 holds up by described silencing means 13, reduce the gap between described upper cover 11 and the top board 12-1 of described radial seal assembly, avoid the strike note sent when operating theater instruments 103 outwards withdraws.Meanwhile, when operating theater instruments 103 is inwardly gone forward one by one, due to the cushioning effect of described silencing means 13, avoid when operating theater instruments is inwardly gone forward one by one and knock.Like this, when operating theater instruments 103 moves back and forth in perforator, can not knock, thus achieve the object of noise reduction.
