Description
Technical field
This utility model relates to field of medical device, is in particular a kind of wall-like tissue penetration fixture.
Background technology
Puncture and be fixedly one of most basic operation in surgical operation, by puncture and fixing operation just can set up a stable passage in human body, can realize the operation of follow-up drain, puncture or shutoff simultaneously by this passage.
But, puncture and fixing normally to operate respectively in existing technology, the Centesis instrument such as puncture awl, the puncture needle etc. that needed use one special before this in the thoracic cavity of human body, fixture is then fixed on passage by abdominal cavity or other wall-like tissues open channel that punctures out again.Such mode troublesome poeration, the operation tool that will use are many, particularly at some special Curing circumstance, such as, in battlefield medical treatment, field medical, emergency treatment, armarium is had higher requirement, carrying out medical rescue to reach more flexible, just requiring that entrained medical apparatus and instruments is the least possible and purposes is many as far as possible.As the puncture of one of operation most basic in current surgical operation and fixing, in existing armarium, still there is not a kind of training equipment that can be good at meeting the demand.
Utility model content
The present utility model object is: provide a kind of wall-like tissue penetration fixture, its structure is simple, easy to use, can when not by realizing puncture and fixing, of many uses when other instruments simultaneously.This utility model is achieved by the following scheme:
A kind of wall-like tissue penetration fixture, is characterized in that: comprise stationary pipes and be set in the inner sleeve that in stationary pipes, also the relative stationary pipes of energy is movable;
Described stationary pipes is provided with at least two and is rotationally connected and around the puncture awl outer wall assembly being laid in stationary pipes front end face surrounding, correspondingly on the front end face of inner sleeve is provided with and each puncture awl outer wall assembly puncture awl inwall assembly one to one;
Puncture awl outer wall assembly is slightly longer than by puncture awl inwall assembly, each puncture awl inwall assembly with and its corresponding puncture awl outer wall assembly front end be rotationally connected and form puncture awl component units; Each puncture awl component units laid around stationary pipes gathers rear formation can puncturing structure;
The locking mechanism for locking both displaced posi or unlock is provided with between the rear end tube wall of described stationary pipes and inner sleeve; Be provided with the position-limit mechanism of outwardly convex outside stationary pipes tube wall, the axial distance between position-limit mechanism and stationary pipes front end face equals or slightly larger than the thickness of wall-like tissue.
At least there are following two kinds of optimal ways about thorn cone composition is single:
Mode one: the described puncture awl component units laid around stationary pipes has six, what each puncture awl component units gathered rear formation flat can puncturing structure.
Mode two: around stationary pipes lay described puncture awl component units have eight, each puncture awl component units gather rear formation cone-shaped can puncturing structure.
This programme is different from structure previously completely, the effect of pyramidal structure and alternative traditional puncture awl or puncture needle that each puncture awl component units gathers rear formation is directly punctured to wall-like tissue, and spacing effect is played after puncture awl component units opens outwards upset, now jointly clamp wall-like tissue inside and outside puncture awl component units and position-limit mechanism thus to realize stationary pipes and inner sleeve fixing, achieve a multi-purpose effect of structure by distortion.
Here, puncture awl outer wall assembly is slightly longer than by puncture awl inwall assembly is can be fitted in the middle of the inwall of wall-like tissue completely in order to ensure puncture awl component units, after fixation simultaneously, self-assembling formation triangle rock-steady structure between puncture awl inwall assembly, puncture awl outer wall assembly and stationary pipes, makes fixing more firm.
Its using method and work process as follows:
Early-stage preparations step: as shown in Figures 1 and 2, make puncture awl component units in gather formation pyramidal structure, and lock locking mechanism the form trait of now pyramidal structure is fixed, when the wall-like for puncture is organized blocked up as coat of the stomach, in order to allow pyramidal structure better puncture, pre-otch process can be done on the surface of wall-like tissue.
Step 1: put pipe, first grips the body of stationary pipes and utilizes the pyramidal structure of front end to thrust wall-like tissue until the wall contacts of wall-like tissue is to position-limit mechanism, illustrates that now stationary pipes has punctured and puts in place;
Step 2: fixing, as shown in Figures 3 to 6, first locking mechanism is unlocked, then grip the body of stationary pipes on the other hand, another hands, by inner sleeve slowly pushed forward thus outwards opened by the inwall assembly pushing tow outer wall assembly being arranged on front end, makes each puncture awl component units outwards overturn and tip upside down on the inwall of wall-like tissue;
Now, maintain this state of puncture awl component units and again locking mechanism locked, thus wall-like tissue holder to be held between puncture awl component units and position-limit mechanism thus to complete stationary pipes fixing in wall-like tissue.
Step 3: remove pipe, after to be used, by the spacing releasing of position-limit mechanism, then inner sleeve is pulled back make puncture awl component units again in gather thus remove the fixing of stationary pipes, finally extract out whole for stationary pipes.
In order to better implement this utility model, this utility model additionally provides following preferred scheme:
Preferably, the tip portion of puncturing structure thin film can be covered with.
When puncture, thin film can better make each puncture awl component units better gather together, and prevents too early the opening of puncture awl component units in the process of puncture.
Preferably, the tip portion that described puncture awl inwall assembly is connected with corresponding puncture awl outer wall assembly is provided with blade.
In the middle of the process of puncture, utilize blade can cut open wall-like tissue better, make puncture more smooth and easy.
Further, described locking mechanism is by being arranged on inside stationary pipes tube wall or projection limit assembly on one of inner sleeve outer wall is formed.
Further, described position-limit mechanism is the spacing ring around being laid in outside stationary pipes tube wall.
Further, the shape of cross section of described stationary pipes and inner sleeve all with can the rear shape of puncturing structure consistent.
Compared to pipe, the pipe fitting of such shape can allow puncture awl component units better outwards overturn.
Technology comparatively, the beneficial effects of the utility model are:
Because this utility model front end has cone structure, therefore when himself the puncture working of wall-like tissue namely can not be completed by when puncture awl or puncture needle, then the cone structure inner surface that launches to surrounding to tip upside down on wall-like tissue coordinates with position-limit mechanism thus realizes fixing, simple to operation;
