Abstract
The invention relates to a disposable uterine cavity tissue suction tube and belongs to the technical field of medical instruments. The tube comprises a tube body (3) made of medical polymer material, the front end of the tube body (3) is provided with a suction tube head (1), the side of the suction tube head (1) is provided with three suction ports (2), and the rear end of the tube body (3) is provided with a connecting structure (4) made of the medical polymer material. The tube is characterized in that the tube body (3) and the connecting structure (4) are manufactured integrally; an included angle a is formed between the central lines of the suction tube head (1) and tube body (3) at 10 degree; the suction ports (2) are distributed circumferentially and evenly, and the distance L from the front ends of the suction ports (2) to the front end of the suction tube head (1) ranges from 5mm to 10mm. The tube is simple in structure and reliable to use and is capable of sucking tissue in a uterine cavity clearly and completely, and the operation effect can be improved greatly.
Description
Technical field
The present invention relates to a kind of disposable uterine cavity tissue suction tube of obstetrics and gynecology department, belong to technical field of medical instruments.
Background technology
Traditional uterine cavity tissue sucker is rustless steel Integral hollow pipe, and its front portion is slightly bending, and a suction port is established in side, front end, and rear end connects suction pump by rubber tube.This suction catheter repeatedly uses, if sterilization is not strict, is easy to cause patient's cross infection.
There is disposable uterine cavity tissue sucker afterwards, it adopts medical macromolecular materials to make, this kind of disposable uterine cavity tissue suction tube mainly comprises the attraction body of hollow, the front end of body is attracted to close also slightly bending, the side, front end of body is attracted to offer a suction port, the rear end of body is attracted to connect one for connector, for being connected with suction pump by rubber tube.There is following defect in this kind of disposable uterine cavity tissue suction tube: 1, owing to attracting to be Split type structure between body and connector, there is packing less phenomenon sometimes in connecting portion, use the Establishment of Stable of negative pressure in middle impact pipe, affect surgical effect, and split-type structural adds assembly process, be unfavorable for reducing costs; 2, suction port only has one and distance attracts the front end of body comparatively far away usually, and during operation, suction port can not touch the place that cornua uteri, fallopian tube both sides etc. are difficult to touch, and the tissue substance in corner cannot be blotted only; 3, attract the design of the angle of bend of the sweep of body front end unreasonable, the place attracting body to be difficult to touch cornua uteri, fallopian tube both sides etc. to be difficult to touch, affects surgical effect.In addition, the position that the connector of existing disposable uterine cavity tissue suction tube is connected with rubber tube is round tube, uses middle rubber tube easily to come off, impact operation.
Summary of the invention
For the above-mentioned defect existed in prior art, the invention provides a kind of use reliable, intrauterine tissue substance fully can be blotted clean disposable uterine cavity tissue suction tube.
The present invention implements by following technical solution: a kind of disposable uterine cavity tissue suction tube, comprise the attraction body be made up of medical macromolecular materials, the front end of described attraction body is for attracting tube head, the side of tube head is attracted to be provided with suction port, the syndeton attracting the rear end of body to be provided with medical macromolecular materials to make, its special character is, described attraction body and syndeton are integrally made; Described attraction tube head is an angle a with the centrage of attraction body, and described angle a is 10 degree; Described suction port is circumferentially equally distributed three, and the front end of described suction port distance attracts the distance L of the front end of tube head to be 5mm-10mm.
During in order to prevent from being connected with rubber tube, rubber tube comes off, and the rear end of described syndeton is conical pipe, and the outside of conical pipe is with saw shape tooth.
Structure of the present invention is simple, integrally makes structure, attract the problem that there is not leakage between body and syndeton, be conducive to the Establishment of Stable of managing interior negative pressure, improve surgical effect owing to attracting body and syndeton to adopt; The present invention is by the attraction angle of bend of tube head and the position of suction port and quantitative design, and the place that attraction tube head can be made to touch cornua uteri, fallopian tube both sides etc. be difficult to touch, blots the tissue substance in corner only, greatly improve surgical effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, attract tube head, 2, suction port, 3, attract body, 4, syndeton.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated:
As shown in drawings, a kind of disposable uterine cavity tissue suction tube, comprises attraction body 3, the syndeton 4 be made up of medical macromolecular materials.Attraction body 3 is hollow pipe, and its front end, for attracting tube head 1, attracts the front end of tube head 1 to close, and attracts the side of tube head 1 to be provided with three suction ports 2 along its even circumferential, and the front end distance of described suction port 2 attracts the distance L of the front end of tube head 1 to be 5mm-10mm.Attract tube head 1 to be an angle a with the centrage of attraction body 3, described angle a is 10 degree.Syndeton 4 is located at the rear end attracting body 3, and its inner hollow also communicates with attracting the cavity of body 3, and its rear end is connected with suction pump by rubber tube.Body 3 and syndeton 4 is attracted integrally to make.
During in order to prevent from being connected with rubber tube, rubber tube comes off, and the back end design of the syndeton 4 in the present embodiment is conical pipe, and the outside of conical pipe is with saw shape tooth.
Other parts in the present invention adopt prior art, do not repeat them here.
Claims (2)
1. a disposable uterine cavity tissue suction tube, comprise the attraction body (3) be made up of medical macromolecular materials, the front end of described attraction body (3) is for attracting tube head (1), the side of tube head (1) is attracted to be provided with suction port (2), attract the rear end of body (3) to be provided with the syndeton (4) that medical macromolecular materials make, it is characterized in that: described attraction body (3) and syndeton (4) are integrally made; Described attraction tube head (1) is an angle a with the centrage of attraction body (3), and described angle a is 10 degree; Described suction port (2) is circumferentially equally distributed three, and the front end of described suction port (2) distance attracts the distance L of the front end of tube head (1) to be 5mm-10mm.
