Abstract
This utility model provides a kind of endoscopic surgery puncture sheath, comprise the convergent divergent channel of hollow, the top of described convergent divergent channel is provided with the seal member for sealing described convergent divergent channel, the side on the top of described convergent divergent channel is communicated with gas tube, on described gas tube, valve is installed, described convergent divergent channel is arranged with the tablet that can move along described convergent divergent channel, the center of described tablet offers circular open, the bottom of described convergent divergent channel is through the circular open of described tablet, the bottom of described tablet is provided with mucigel, described mucigel is intended for a side of the gas outlet of described convergent divergent channel.Therefore, endoscopic surgery puncture sheath of the present utility model has simple in structure, produces and is easy to advantage.
Description
Technical field
This utility model belongs to technical field of surgical instruments, specifically, relates to a kind of endoscopic surgery puncture sheath.
Background technology
Endoscopic surgery dilator is to be all provided with spiral lamination on the body surface of convergent divergent channel, utilizes the frictional force between spiral lamination and the wound of the body operation place of opening mouth to fix surgical dilator in the time performing an operation.This endoscopic surgery dilator can play fixation in the time of operation, but its shortcoming is: when surgical dilator turnover human body, need to rotate body, turnover is inconvenient, the bad adjusting of the degree of depth, and the rotation of dilator easily strengthens the injury of wound.
Before inventor of the present utility model, the Chinese utility model CN203303091U of application discloses a kind of endoscopic surgery dilator, comprise convergent divergent channel, seal member, paperboard and the tight loop of hollow, the side on the top of described convergent divergent channel is communicated with gas tube, on described gas tube, valve is installed, described seal member is arranged on the inside on the top of convergent divergent channel, described tight loop is fixed in paperboard, and the bottom of described convergent divergent channel is passed tight loop and paperboard and is fixed in paperboard.This utility model can stick on paperboard on human body, utilize frictional force between tight loop and the body of convergent divergent channel in paperboard to fix the position of dilator, facilitate dilator turnover human body, its degree of depth is easily regulated, and on body, there is no spiral lamination, the injury can reduce dilator turnover human body time, wound being caused.
But the paperboard of this utility model and tight loop are made trouble, there is the defect of the bad assurance of processing technology.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of endoscopic surgery simple in structure puncture sheath, to overcome defect of the prior art.
To achieve these goals, this utility model provides a kind of endoscopic surgery puncture sheath, comprise the convergent divergent channel of hollow, the top of described convergent divergent channel is provided with the seal member for sealing described convergent divergent channel, the side on the top of described convergent divergent channel is communicated with gas tube, on described gas tube, valve is installed, described convergent divergent channel is arranged with movably tablet, the center of described tablet offers circular open, the bottom of described convergent divergent channel is through the circular open of described tablet, described tablet bottom be provided with mucigel, described mucigel is intended for a side of the gas outlet of described convergent divergent channel.
As further illustrating of sheath that endoscopic surgery described in the utility model is punctured, preferably, the thickness of the Thickness Ratio edge of the center of described tablet is large.
As further illustrating of sheath that endoscopic surgery described in the utility model is punctured, preferably, the internal diameter of described circular open is less than the external diameter of described convergent divergent channel.
As can be seen here, because this utility model is arranged with movable tablet by design on convergent divergent channel, on tablet, offer circular open, the bottom of convergent divergent channel is through the circular open of tablet, the bottom of tablet is provided with mucigel, mucigel, towards the structure of a side of the gas outlet of convergent divergent channel, has endoscopic surgery puncture sheath of the present utility model simple in structure, produces the feature of being easy to.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of endoscopic surgery puncture sheath of the present utility model;
Fig. 2 is the top view of tablet of the present utility model.
Description of reference numerals is as follows:
Convergent divergent channel 1, seal member 2, gas tube 3, valve 31, tablet 4, circular open 41, viscose 42, gas outlet 5.
Detailed description of the invention
In order to make auditor can further understand structure of the present utility model, feature and other objects, now being accompanied by accompanying drawing in conjunction with appended preferred embodiment is described in detail as follows, the illustrated embodiment of this accompanying drawing is only for the technical solution of the utility model is described, and non-limiting this utility model.
In figure, only indicate the main position relevant to this utility model, first, please refer to Fig. 1, Fig. 1 is the overall structure schematic diagram of endoscopic surgery puncture sheath of the present utility model.As shown in Figure 1, the endoscopic surgery puncture sheath that this utility model provides comprises the convergent divergent channel 1 of hollow, the top of convergent divergent channel 1 is provided with the seal member 2 for sealing convergent divergent channel 1, the side on the top of convergent divergent channel 1 is communicated with gas tube 3, valve 31 is installed on gas tube 3, and convergent divergent channel 1 is arranged with movably tablet 4.As shown in Figure 2: the center of tablet 4 offers circular open 41, the bottom of convergent divergent channel 1 is through the circular open 41 of tablet 4, the bottom of tablet 4 is provided with mucigel 42, mucigel 42 is intended for a side of the gas outlet 5 of convergent divergent channel 1, in addition, the internal diameter of circular open 41 is slightly less than the external diameter of convergent divergent channel 1, and the thickness of the Thickness Ratio edge of the center of tablet 4 is large, more flexible of tablet 4, fixes tightlyer to convergent divergent channel 1.In addition, tablet 4 of the present utility model is made up of elastomeric material (common elastomeric material), and the rear sterilization of processing mucigel 42 has endoscopic surgery puncture sheath of the present utility model simple in structure, produces the feature of being easy to.
Need statement, above-mentioned utility model content and detailed description of the invention are intended to prove the practical application of technical scheme that this utility model provides, and should not be construed as the restriction to this utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various amendments, be equal to and replace or improve.Protection domain of the present utility model is as the criterion with appended claims.
