The beneficial effects of the utility model are that: have long service life, stable performance, the convenient characteristics of disinfection.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to one and can make percutaneous renal puncture rubble and take stone, can be used for again punctio vesicae and make Multifunction puncture sheath repeatly.
Background technology
Puncturing used by sheath on existing market is all disposable plastic thin skin sheath, it is for reaching company's interest maximization, in patient's operation process, existing puncture sheath stability is used to be not added with, easily bring trouble unnecessary in operation process, and be made by plastic material, sterilization inconvenience, it is all disposable for using.
Summary of the invention
The purpose of this utility model is in that the deficiency overcoming prior art to exist, and provides a kind of long service life, stable performance, the convenient Multifunction puncture sheath of sterilization.
The purpose of this utility model completes by following technical solution.This Multifunction puncture sheath, including main sheath pipe, connecting rod, the front end tube wall of described main sheath pipe offers backwater hole, and the end of main sheath pipe is fixed with sheath pipe joint by laser weld mode, and this sheath pipe joint is cased with silicon rubber cup；Being fixed with connecting rod by laser weld mode on the tube wall of main sheath pipe, the inner core of this connecting rod communicates with the inner core of main sheath pipe；Being also associated with bath joint in connecting rod, one end of this bath joint is embedded in the interior in-core of connecting rod, and the outer wall of this connecting rod is connected fixing with the outer wall joint of bath joint by adapter sleeve.
As preferably, the tube wall of described main sheath pipe being cased with lock sleeve, lock sleeve is provided with lock screw.
As preferably, the bar wall of described connecting rod offering pressure port.
The beneficial effects of the utility model are: have long service life, stable performance, the convenient feature of sterilization.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks cross-sectional view.
Label in accompanying drawing is respectively as follows: 1, main sheath pipe；2, connecting rod；3, sheath pipe joint；4, silicon rubber cup；5, bath joint；6, adapter sleeve；7, lock sleeve；8, lock screw；11, backwater hole；21, pressure port.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model done detailed introduction: as shown in Figure 1, this utility model includes main sheath pipe 1, connecting rod 2, offering backwater hole 11 on the front end tube wall of described main sheath pipe 1, this backwater hole 11 has the smoothness reducing drag effect and raising Multifunction puncture sheath turnover human body；Reduce resistance, it is to avoid scratch tissue owing to tissue is produced friction by main sheath pipe 1, and the tissue clavus scratched is taken out of human vitronectin, cause the secondary injury to patient；The end of main sheath pipe 1 is fixed with sheath pipe joint 3 by laser weld mode, and this sheath pipe joint 3 is cased with silicon rubber cup 4, presses puncturing lever, puncturing head reach running that silicon rubber cup 4 can promote main sheath pipe 1 built-in；Being fixed with connecting rod 2 by laser weld mode on the tube wall of main sheath pipe 1, the inner core of this connecting rod 2 communicates with the inner core of main sheath pipe 1；Being also associated with bath joint 5 in connecting rod 2, one end of this bath joint 5 is embedded in the interior in-core of connecting rod 2, and the outer wall of this connecting rod 2 is connected fixing with the outer wall joint of bath joint 5 by adapter sleeve 6, and this bath joint 5 is external rinses pipe.
In addition the graduation mark that main sheath pipe 1 is indicated, can enter the degree of depth and the either shallow of human body by the high-visible movable puncture sheath that adjusts, be fixed on human vitronectin to avoid inserting deep or exiting (passage mistake).
Being cased with lock sleeve 7 on the tube wall of described main sheath pipe 1, lock sleeve 7 is provided with lock screw 8；The main sheath pipe 1 anchor ear principle banding sheath bar by lock sleeve 7 and lock screw 8, thus will not make epitheca club shaft depression, play hollow；Can help the mid-sheath degree of depth of operation technique is fixed, to avoid inserting deep or exiting (passage mistake).
The bar wall of described connecting rod 2 offers pressure port 21, increase pressure port 21 can be held, produce air pressure inside and strengthen puncture dynamics；Air pressure is reduced after relieving.The size of negative pressure suction force can be controlled by pressing this pressure port 21, thus ensure that and taking in stone process making percutaneous renal puncture rubble, in kidney, be in low-pressure state, it is to avoid perfusion salt water excess, water exosmoses, and especially urinates the generation of pyemia.
This utility model is not limited to above-mentioned embodiment, no matter making any change, every employing structural design provided by the utility model on its shape or material are constituted, being all a kind of deformation of the present utility model, being all considered as within this utility model protection domain.
