Abstract
The utility model is a kind of per anum single hole puncturing structure of depth-adjustable.It includes puncture tube, adjustment structure and the position limiting structure for being set to puncture tube outer surface；Position limiting structure its outer diameter in puncture tube use process, which is greater than, punctures pipe outside diameter, and outer diameter is greater than the part for puncturing pipe outside diameter at a distance from puncture tube head end by adjustment structure adjusting in position limiting structure.For the prior art, utility model has the advantages that limiting the depth that puncture tube enters patient's body by adjusting position limiting structure at a distance from puncture tube head end.
Description
Technical field
The utility model relates to medical instruments field, the per anum single hole puncturing structure of especially a kind of depth-adjustable.
Background technique
On existing market, for increasing increasingly for Transanal procedure, and currently on the market in the form of silica gel existing for notch
Dilator protective case is few, mainly exists with plastic form, but most feedbacks currently on the market, the position that need to be performed the operation by patient
The position set apart from anus is different, has different requirements for the depth that incision distraction device protective case enters patient's body.And
Incision distraction device on the market exists almost without the product that there is adjustable working depth.
Summary of the invention
The purpose of this utility model is to provide a kind of per anum single hole puncturing structures of depth-adjustable.
The purpose of this utility model is achieved through the following technical solutions: a kind of per anum single hole puncture knot of depth-adjustable
Structure, it is characterised in that: it includes puncture tube, adjustment structure and the position limiting structure for being set to puncture tube outer surface；Position limiting structure
In puncture tube use process its outer diameter be greater than puncture pipe outside diameter, and in position limiting structure outer diameter be greater than puncture pipe outside diameter part with
The distance of puncture tube head end is adjusted by adjustment structure.
For the prior art, utility model has the advantages that
By adjusting position limiting structure at a distance from puncture tube head end, the depth that puncture tube enters patient's body is limited.

Specific embodiment
The content of the present invention is described in detail with embodiment with reference to the accompanying drawings of the specification:
A kind of implementation of the per anum single hole puncturing structure of depth-adjustable provided by the utility model illustrates as shown in figures 1-8
It is intended to.It includes puncture tube 1, adjustment structure and the position limiting structure for being set to 1 outer surface of puncture tube；Position limiting structure is in puncture tube
Its outer diameter is greater than 1 outer diameter of puncture tube in 1 use process, and outer diameter is greater than part and the puncture of 1 outer diameter of puncture tube in position limiting structure
The distance of 1 head end of pipe is adjusted by adjustment structure.Since the outer diameter of position limiting structure is greater than puncture tube 1, anus is penetrated in puncture tube
Afterwards, position limiting structure is stuck in anal orifice, and it is exactly puncture tube 1 that position limiting structure, which is stuck in the position of anal orifice at a distance from 1 head end of puncture tube,
Into the depth of patient's body.
According to the difference of position limiting structure and adjustment structure, the utility model can be extended out following two embodiment:
Embodiment 1
As shown in Figs 1-4: the position limiting structure is snap ring 21, and the adjustment structure is to be set on the inside of snap ring 21 to be equipped with
Internal screw thread 22 and it is arranged on the outside of puncture tube 1 and is equipped with the external screw thread 23 that extends along 1 length direction of puncture tube.
Puncture tube 1 and snap ring 21 before use, be first assembled together by product.By threaded engagement, snap ring 21 is turned to
The tail portion of puncture tube 1.
When product uses in two steps: step 1, anus, and percentage regulation being filled in into the front end of puncture tube 1.Step 2,
Rotary clip 21 is bonded snap ring 21 outside anus.Puncture tube 1 can connect platform and perform the operation later.
Embodiment 2
As viewed in figures 5-8: the position limiting structure is the inflatable material 31 that ring is set to 1 outer surface of puncture tube, the adjusting
Structure is the gas ducting 32 for inflating to inflatable material 31 connecting with inflatable material 31.
When product uses in two steps: step 1, anus, and percentage regulation being filled in into the front end of puncture tube 1.Step 2,
Gas ducting 32 connects charger, is inflated to inflatable material 31, the part for being exposed at inflatable material 31 other than anus is filled
Divide expansion.Puncture tube 1 can connect platform and perform the operation later.
From Fig. 7,8 as can be seen that the degree difference that inflatable material 31 is inflated, puncture tube 1 enter the depth of patient's body
It is different.
On the basis of embodiment 1,2, the head end outer wall of puncture tube 1 is additionally provided with the anticreep snap ring for preventing puncture tube 1 from falling off
11.Frictional force between anticreep snap ring and tissue, can slip to avoid puncture tube 1.
The tail end of puncture tube 1 is equipped with bore gradually big guide structure 12 from front to back.Guide structure 12 can facilitate instrument
Guidance.
