Abstract
The invention discloses a medical instrument sheath which is used for being in cooperation with an endoscope for use. The medical instrument sheath comprises a sheath tube and an inner core, wherein the inner core is sleeved with the sheath tube. One end of the sheath tube is connected with an air bag, the air bag wraps the periphery of the end portion of the sheath tube, the sheath tube is provided with an air inflation catheter and a clamping opening, the air inflation catheter is connected with the air bag of the end portion of the sheath tube, and the clamping opening is matched with the endoscope in a locking mode. The air bag is designed on the end portion of the sheath tube, the air bag wraps the end portion of the sheath tube, and the surgical space is expanded through expansion of the air bag. When the medical instrument sheath is in cooperation with the endoscope for use, the endoscope can be protected, the better view and the better space are provided for the observation and a surgery, and therefore the aim of improving the safety rate of the surgery is achieved.
Description
Technical field
The present invention relates to a kind of medical equipment, specifically, relate to a kind of apparatus sheath.
Background technology
The improvement of the raising of the rise of Wicresoft's medical science, especially interventional technique and intervention apparatus in recent years, make the application of interventional medicine more and more extensive.Get involved the guiding that relies on medical imaging device, utilize puncture and microcatheter technology disease is diagnosed and treated, and take treatment as a main subject.It has that accurate positioning, wound are little, few intercurrent disease, curative effect are high, instant effect, the repeatable characteristics such as strong.Interventional therapy has become and medical treatment, surgical intervention the third-largest clinical treatment means arranged side by side.
Present medical equipment sheath on the market, as the apparatus of getting involved human body, provides a passage for endoscope enters field of operation.Present exploration technology, normally insert the medical equipment sheath from chamber and the wound of human body, camera lens enters people's in-vivo tissue thereupon and observes.Yet,, due to art district spatial constraints in human body, make the endoscope visual field limited, can not clearly observe and operation effectively, increased operation risk, cause the operation safety rate to reduce.
Summary of the invention
The object of the present invention is to provide a kind of medical equipment sheath, in the end of sheath pipe, be designed with air bag, the expansion by air bag enlarges operative space, can more clearly observe and more effectively operation.
To achieve these goals, the technical solution adopted in the present invention is as follows:
A kind of medical equipment sheath, be used for coordinating endoscope to use, comprise the sheath pipe and be set in inner core among described sheath pipe, described sheath Guan Yiduan is provided with air bag, it is peripheral that described air bag is wrapped in described sheath tube end, described sheath pipe has inflating catheter and bayonet socket, and described inflating catheter connects the described air bag of described sheath tube end, and described bayonet socket is locked and coordinated with described endoscope.
Further, described sheath pipe adopts disposable plastic to make.
Further, described sheath pipe adopts reusable metal material to make.
Further, described inflating catheter enters described air bag by the inwall passage of injector to inject gas or the described sheath pipe of liquid process.
Further, described inflating catheter enters described air bag by the centre gangway of injector to inject gas or the described sheath pipe of liquid process.
Compared with prior art, sheath tube end of the present invention is designed with air bag, air bag parcel sheath tube end, and the expansion by air bag enlarges operative space, for observing and operation provides the better visual field and space, thereby reaches the purpose that improves the operation safety rate.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, medical equipment sheath of the present invention is described further.
See also Fig. 1, Fig. 2 and Fig. 3, be the first embodiment of medical equipment sheath of the present invention, described medical equipment sheath be used for to coordinate endoscope to use, and comprises sheath pipe 1 and is set in inner core 2 among described sheath pipe 1.Described sheath pipe 1 one ends are provided with air bag 3, and described air bag 3 is wrapped in 11 peripheries, described sheath pipe 1 end.Described sheath pipe 1 has inflating catheter 12 and bayonet socket 13, and described inflating catheter 12 connects the described air bag 3 of described sheath pipe 1 end 11, and described bayonet socket 13 is locked and coordinated with described endoscope.
See also Fig. 1, Fig. 2 and Fig. 3, described sheath pipe 1 can adopt disposable plastic to make, and also can adopt reusable metal material to make.In the present embodiment, described inflating catheter 12 is by injector to inject gas or liquid, and gas or liquid enter described air bag 3 through the inwall passage 14 of described sheath pipe 1, form a larger air bag space.The present invention is not limited to this, and in other embodiments, described sheath pipe 1 also can adopt other materials to make, and described inflating catheter 12 can also other modes enter described air bag 3 by injector to inject gas or liquid.
See also Fig. 3 and Fig. 7, when described medical equipment sheath and endoscope 4 are used in conjunction with, after described air bag 3 is restarted, described air bag 3 expands and is wrapped in 11 peripheries, described sheath pipe 1 end, described endoscope 4 front ends enter described air bag 3 centers of expansion, across transparent balloon membranes, the tissue outside described air bag 3 are observed.Described medical equipment sheath coordinates described endoscope 4 to use, and can enter operative region, enlarges the range of observation of described endoscope 4 and protects described endoscope 4, for accurately performing the operation smoothly, provides better condition.
See also Fig. 4, Fig. 5 and Fig. 6, the second embodiment for medical equipment sheath of the present invention, the difference of itself and described the first embodiment is: described inflating catheter 12 is by injector to inject gas or liquid, gas or liquid enter described air bag through the centre gangway 15 of described sheath pipe 1, form a larger air bag space.
The present invention is because described sheath pipe 1 end 11 is designed with described air bag 3, described air bag 3 parcel described sheath pipe 1 ends 11, expansion by described air bag 3 enlarges operative space, for observing and operation provides the better visual field and space, thereby reaches the purpose that improves the operation safety rate; , due to described air bag 3 parcel described sheath pipe 1 ends 11, when described medical equipment sheath and described endoscope 4 are used in conjunction with, can reach the effect of the described endoscope 4 of protection simultaneously.
More than describe preferred embodiment of the present invention in detail, should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variations.Therefore, all technical staff in the art according to the present invention design on the prior art basis by logical analysis, reasoning or technical scheme available according to limited experiment, all should be among the determined protection domain by these claims.
