Abstract
The utility model discloses a screw-type J-shaped medical guiding tube comprising a hollow medical guiding tube whose one end or two ends are bent into the J-shape, and the medical guiding tube is a screw tubular tube body. The external wall of the medical guiding tube is in a three-edge shape or a multiple-edged shape, and the cross section of an inner hole is a round. Since the medical guiding tube is the three-edge shape or the multiple-edged shaped screw tubular body and forms a certain angle with a ureter, along with the crawl of the ureter, the edges of the screw type tube body can push calculus or foreign materials to move down, thereby realizing the good effect of removing calculus and draining, improving the speed of draining, reducing the operation time and reducing the dangerous of operation.
Description
(1) technical field
This utility model relates to the medical catheter technical field, relates in particular to a kind of spiral J type medical catheter that is used for effects such as drain in the ureter, external drainage and expansion, support ureter.
(2) background technology
In medical procedure, usually run into and the patient carried out situations such as ureter drain, calculus, support, J type medical catheter (having another name called ureter bracket) commonly used is for cylindrical, it abuts against with duct wall after inserting ureter, effectively drain, calculus, and use single not easy to operately, can't effectively observe speed and position that conduit enters, be not easy to take out.In order to overcome above-mentioned drawback, I have developed J type medical catheter external member, have authorized utility model patent, and the patent No. is ZL200720027933.5, one of its feature is rhizoma sparganic shape or many ribs shape for described medical catheter outer wall, and sidewall is provided with scale and conduction hole.It act as and can form drainage channel outside body, has effectively solved the awkward problem of J type medical catheter, and drain, lithagogue effect are good, but still exists drain speed can not satisfy the problem of requirements of operation during actual the use.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of spiral J type medical catheter, can improve drain speed, shortens operating time, and it is dangerous to reduce operation, has better drain, lithagogue effect.
This utility model is realized by following measure: a kind of spiral J type medical catheter, comprise that one or both ends are bent into the medical catheter of the hollow of J type, and described medical catheter is the helix body.
The further improvement of the utility model part is: the outer wall of described medical catheter is rhizoma sparganic shape or many ribs shape, and the endoporus cross section is circular.
The beneficial effects of the utility model:
Because being rhizoma sparganic or many prismatics helical form body and ureter, described medical catheter formed certain angle, along with ureteral wriggling, the corner angle of helical form body can promote calculus or foreign body moves down, thereby reached better calculus drainage effect, improved drain speed, shorten operating time, it is dangerous to reduce operation.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
1 endoporus among the figure, 2 outer walls, 3 medical catheters, 4 calculus, 5 ureters.
(5) specific embodiment
A kind of spiral J type medical catheter as shown in Figure 1 comprises that one or both ends are bent into the medical catheter 3 of the hollow of J type, and described medical catheter 3 is the helix body.
The outer wall 2 of medical catheter 3 described in the utility model is rhizoma sparganic shape or many ribs shape, and endoporus 1 cross section is circular.
Because described medical catheter 3 has formed certain angle with ureter 5, strengthened the drain space during drain,, thereby reached better calculus drainage effect along with the wriggling of ureter 5 can promote calculus 4 or foreign body moves down.
Claims (2)
1. spiral J type medical catheter, comprise that one or both ends are bent into the medical catheter of the hollow of J type (3), is characterized in that: described medical catheter (3) is the helix body.
2. according to the described spiral J type medical catheter of claim 1, it is characterized in that: the outer wall (2) of described medical catheter (3) is rhizoma sparganic shape or many ribs shape, and endoporus (1) cross section is circular.
