Abstract

The invention relates to a multifunctional puncture sheath which comprises a main sheath tube and a connecting rod. The tube wall of the front end of the main sheath tube is provided with a water return hole, a sheath tube joint is fixed to the tail end of the main sheath tube in a laser welding manner, and the sheath tube joint is sleeved with a silica gel cap. The connecting rod is fixed to the tube wall of the main sheath tube in a laser welding mode, and an inner core of the connecting rod is communicated with an inner core of the main sheath tube. The connecting rod is internally further connected with a flushing joint, one end of the flushing joint is embedded in the inner core of the connecting rod, and the joint of the outer wall of the connecting rod and the outer wall of the flushing joint are fixedly connected through a connecting sleeve. The tube wall of the main sheath tube is sleeved with a locking sleeve, the locking sleeve is provided with a lock screw, and the rod wall of the connecting rod is provided with a pressure hole. The multifunctional puncture sheath has the advantages of being long in service life, stable in performance and convenient to disinfect.

Description

A kind of Multifunction puncture sheath
Technical field
The invention belongs to technical field of medical instruments, particularly relate to one and can make percutaneous renal puncture rubble and get stone, can be used for again punctio vesicae and make Multifunction puncture sheath repeatly.
Background technology
What the puncture sheath on existing market was used is all disposable plastic thin skin sheath, maximize for reaching company's interest, in patient's operation process, existing puncture sheath stability is used not add, easily bring trouble unnecessary in operation process, and be made by plastic material, sterilization is inconvenient, and it is all disposable for using.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of long service life, stable performance are provided, Multifunction puncture sheath easily of sterilizing.
The object of the invention is to have come by following technical solution.This Multifunction puncture sheath, comprises main sheath pipe, connecting rod, and 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 on this sheath pipe joint, cover has silicon rubber cup; The tube wall of main sheath pipe is fixed with connecting rod by laser weld mode, and the inner core of this connecting rod communicates with the inner core of main sheath pipe; Also be connected 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 and fixed by adapter sleeve with the outer wall joint of bath joint.
As preferably, on the tube wall of described main sheath pipe, cover has lock sleeve, and lock sleeve is provided with lock screw.
As preferably, the bar wall of described connecting rod offers pressure port.
Beneficial effect of the present invention is: have long service life, stable performance, a feature easily of sterilizing.
Accompanying drawing explanation
Fig. 1 is that master of the present invention looks cross-sectional view.
Label in accompanying drawing is respectively: 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, detailed introduction is done to the present invention: as shown in Figure 1, the present invention includes main sheath pipe 1, connecting rod 2, the front end tube wall of described main sheath pipe 1 offers backwater hole 11, and this backwater hole 11 has the smoothness reducing drag effect and improve Multifunction puncture sheath turnover human body; Reduce resistance, avoid because main sheath pipe 1 pair of tissue produces friction and scratch tissue, and the clavus of organizing scratched is taken out of human vitronectin, causing the secondary injury to patient; The end of main sheath pipe 1 is fixed with sheath pipe joint 3 by laser weld mode, and on this sheath pipe joint 3, cover has silicon rubber cup 4, and pressing silicon rubber cup 4 can promote the built-in puncturing lever of main sheath pipe 1, puncturing head reach running; The tube wall of main sheath pipe 1 is fixed with connecting rod 2 by laser weld mode, and the inner core of this connecting rod 2 communicates with the inner core of main sheath pipe 1; Also be connected 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 and fixed by adapter sleeve 6 with the outer wall joint of bath joint 5, the external syringe pipe of this bath joint 5.
In addition the graduation mark indicated of main sheath pipe 1, can enter the degree of depth and the either shallow of human body by high-visible movable adjustment puncture sheath, is fixed on human vitronectin to avoid inserting dark or to exit (Tong Dao Lost and lose).
On the tube wall of described main sheath pipe 1, cover has lock sleeve 7, and lock sleeve 7 is provided with lock screw 8; Main sheath pipe 1 passes through the anchor ear principle banding sheath bar of lock sleeve 7 and lock screw 8, epitheca club shaft would not be made like this to cave in, play hollow; Can help to be fixed the mid-sheath degree of depth of operation technique, to avoid inserting dark or exiting (logical road Lost loses).
The bar wall of described connecting rod 2 offers pressure port 21, can hold and increase pressure port 21, produce air pressure inside and strengthen puncture dynamics; Air pressure is reduced after relieving.Can control the size of negative pressure suction force by pressing this pressure port 21, thus ensure that and to get in stone process making percutaneous renal puncture rubble, be in low-pressure state in kidney, avoid perfusion salt water excess, water exosmoses, and especially urinates the generation of pyemia.
The present invention is not limited to above-mentioned embodiment, no matter do any change, every employing structural design provided by the present invention on its shape or material are formed, is all one distortion of the present invention, all should thinks within scope.
