Abstract
The utility model belongs to the field of medical minimally invasive surgery of the department of surgery, and relates to a nickel-titanium memory alloy needle cannula for surgery. The nickel-titanium memory alloy needle cannula for surgery comprises a cannula, and the cannula is made of nickel-titanium memory alloy materials. The cannula comprises a rear straight pipe and a memory pipe, wherein the rear straight pipe can be connected with a connecting port and the memory pipe can be connected with the rear straight pipe and is of an integrated structure. The memory pipe is a spiral pipe which is formed through the method of cutting the tube wall of the nickel-titanium pipe in the shape of spiral lines by lasers. The memory pipe restores memory at set temperature and becomes a hyper-elastic arc pipe. According to the nickel-titanium memory alloy needle cannula, the shape memory function of the nickel-titanium memory alloy materials is used, so that a designed shape is achieved at the temperature of human body,and the needle cannula can be bent during an intervertebral disc surgery. The nickel-titanium memory alloy needle cannula for surgery can further be used in a surgery, is simple to manufacture, and can be applied to needle cannulas for surgeries with different kinds of needle cannula connecting ports.
Description
Technical field
This utility model belongs to medical science surgery Minimally Invasive Surgery field, relates to a kind of surgical needles sleeve pipe.
Background technology
At present, the intervertebral disc operation needle cannula of using clinically is the straight tube shape, adopts laser to dissolve technology such as intervertebral disc kernel and treats annuler bulge, alleviates patient's pain symptom.But Fibrotic patient acts on not quite for intervertebral disc.Because needle cannula is the straight tube shape, such apparatus cutting can't be finished for this special case in intervertebral disc operation less than relevant tissue, does not reach the purpose for the treatment of.
In addition, in surgical operation, need to get around some organ sometimes, still, existing needle cannula is the straight tube shape, can't reach the operation purpose equally.
The utility model content
In order to solve the above-mentioned technical problem that exists in the background technology, this utility model provides a kind of Ultimum Ti surgical needles sleeve pipe.
Technical solution of the present utility model is:
First kind of Ultimum Ti surgical needles sleeve pipe comprises sleeve pipe, and its special character is: described sleeve pipe is made by Ultimum Ti tubing; Described sleeve pipe comprises the back straight tube 3 that can link to each other with connecting interface 4, links to each other with back straight tube 3 and into a single integrated structure electrostatic storage tube 2; Described electrostatic storage tube 2 is to adopt the laser helical coil that cutting auger line 6 forms on the Ultimum Ti tube wall; The refresh memory under design temperature of described electrostatic storage tube 2 becomes super-elasticity arcuation pipe.
Second kind of Ultimum Ti surgical needles sleeve pipe comprises sleeve pipe, and its special character is: described sleeve pipe is made by Ultimum Ti tubing; Described sleeve pipe comprises the back straight tube 3 that can link to each other with connecting interface 4, links to each other with back straight tube 3 and into a single integrated structure electrostatic storage tube 2; Described electrostatic storage tube 2 is for having the straight tube of a plurality of horizontal strip breach 5; Described a plurality of breach 5 simultaneously along electrostatic storage tube centerline direction and circumference originating party to distribution, the refresh memory under design temperature of described electrostatic storage tube 2 becomes super-elasticity arcuation pipe.
Above-mentioned two kinds of needle cannula also can comprise the connecting interface 4 that links to each other with back straight tube 3.
Above-mentioned two kinds of needle cannula also can comprise with electrostatic storage tube 2 and linking to each other and into a single integrated structure preceding straight tube 1.
The utility model has the advantages that:
1, this utility model provides a kind of Ultimum Ti surgical needles sleeve pipe, utilized the shape memory function of Ultimum Ti material, with excellent biological compatibility, nonmagnetic performance, be issued to the shape of design in human body temperature, make the purpose of needle cannula bending when reaching intervertebral disc operation.
2, this utility model also can be used for surgical operation, and for example puncture operation etc. utilizes the shape memory function of Ultimum Ti material, gets around some organ.
3, this utility model is made simply, applicable various needle cannula connecting interface.
