Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of scope foreign matter snare with locking function
Device.
Background technique
In the prior art, for convenience by intracorporal foreign body, it is often necessary to use foreign body in Microendoscopic
Device is operated.This withdrawing device can only take out the moderate foreign matter of regular shape, volume in the prior art.But in reality
In operation, since the shape of foreign matter in human body can be to be varied, including sharp foreign matter, such as blade, syringe needle etc.
Part small foreign body, the string bag are difficult to be drawn off, and small foreign body may scratch oesophagus；It is also easily broken foreign matter, such as respectively
Kind drug；And foreign matter in irregular shape, such as glass fragment etc..In operation for the above foreign matter, it is easy to make
At the damage of esophagus or mucous membrane of mouth, moreover, these foreign matters tend not to completely take out, or not easily take out.This
Outside, since existing withdrawing device is not provided with locking device, both hands compounding practice is needed until by foreign body, to both hands
Coordination degree it is more demanding, especially foreign matter pass through esophagus inlet when due to sphincter effect, it is easy to cause different
Object is easy to fall off, and secondary medical hidden danger is caused, so that increasing medical difficulty.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of scope foreign matter snare with locking function,
The scope foreign matter snare with locking function is by the fixed setting locking rubber ring in hand-held casing, and by upper connecting rod
Outer diameter is arranged bigger than the aperture of the through-hole on locking rubber ring, using locking rubber ring by pull rod integral locking, solves existing
There is foreign matter snare not have the locking function problem more demanding to the coordination degree of both hands.
The utility model is achieved by the following technical programs.
A kind of scope foreign matter snare with locking function provided by the utility model, including hand-held casing, locking rubber
Cushion rubber, teleflex, wire drawing, takes object gum cover and upper connecting rod at lower pull rod；It is solid by the transition conical surface between the upper connecting rod and lower pull rod
Fixed connection, and upper connecting rod and lower pull rod are through the locking rubber ring being fixed in hand-held casing；The hand-held casing
Lower end is fixedly connected with teleflex, and the both ends of the wire drawing are fixedly connected with the lower end of lower pull rod, and soft set is run through at the middle part of wire drawing
The inside of pipe, and be additionally provided in the middle part of wire drawing and take object gum cover, and object gum cover is taken to be set to except the end of teleflex；The lock
The aperture of through-hole on tight rubber ring is less than the outer diameter of upper connecting rod.
The outer symmetrical of the hand-held casing is fixedly installed finger ring circle.
The finger ring circle and hand-held casing are integrally formed.
The bottom end of the lower pull rod is additionally provided with stop collar.
The top of the upper connecting rod is further fixed on pull ring.
The aperture of through-hole on the locking rubber ring is less than or equal to the outer diameter of lower pull rod.
The utility model has the beneficial effects that: by the fixed setting locking rubber ring in hand-held casing, and will pull-up
The outer diameter of bar is arranged bigger than the aperture of the through-hole on locking rubber ring, using locking rubber ring by pull rod integral locking, solves
Existing foreign matter snare does not have the locking function problem more demanding to the coordination degree of both hands；And using take object gum cover come
Taking foreign body is covered, prevents sharp small foreign body from penetrating, improves the taking-up probability of foreign matter, and ensure that foreign matter will not scratch food
Pipe, so as to avoid damage of the foreign matter to patient during foreign body, can completely take out various shape foreign matter, together
When reduce foreign matter taking-up difficulty.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- pull ring, 2- hold casing, 3- finger ring circle, and 4- locks rubber ring, pull rod under 5-, 6- stop collar, the soft set of 7-
Pipe, 8- wire drawing, 9- take object gum cover, 10- upper connecting rod.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
A kind of scope foreign matter snare with locking function as shown in Figure 1, including hand-held casing 2, locking rubber ring
4, lower pull rod 5, teleflex 7, wire drawing 8, take object gum cover 9 and upper connecting rod 10；Pass through transition between the upper connecting rod 10 and lower pull rod 5
The conical surface is fixedly connected, and upper connecting rod 10 and lower pull rod 5 are through the locking rubber ring 4 being fixed in hand-held casing 2；It is described
The lower end of hand-held casing 2 is fixedly connected with teleflex 7, and the both ends of the wire drawing 8 are fixedly connected with the lower end of lower pull rod 5, wire drawing 8
Middle part run through the inside of teleflex 7, and the middle part of wire drawing 8 is additionally provided with and takes object gum cover 9, and object gum cover 9 is taken to be set to soft set
Except the end of pipe 7；The aperture of through-hole on the locking rubber ring 4 is less than the outer diameter of upper connecting rod 10.
The outer symmetrical of the hand-held casing 2 is fixedly installed finger ring circle 3, and finger ring circle 3 and hand-held casing 2 are integrally formed.
The bottom end of the lower pull rod 5 is additionally provided with stop collar 6, and preventing from excessively pulling up causes to take object gum cover 9 to be damaged by the end of teleflex 7
