Abstract
The utility model discloses a urethra probe contributing to anastomotic guidance of posterior urethra and belongs to the technical field of medical surgical instruments. The urethra probe comprises a probe body, wherein a bending part is formed by extension from one end of the probe body to the outside; a plurality of grooves for guiding anastomotic needles are formed in the outer surface of the bending part at intervals; a flat gripping part is arranged at the other end of the probe body. When the urethra probe is used for posterior urethra anastomosis, the urethra probe extends into the stump of the urethra, and the bending part of the urethra probe opens the urethra; the anastomotic needles touch the grooves which are formed in the surface of the bending part at intervals, and suture is completed by smooth entering and exiting under the guidance action of the grooves; moreover, the injury to the urethra caused by repeated entering and existing of the urethra probe is avoided, the anastomosis accuracy is improved, the side injury is avoided, the operation time is shortened, and complications are reduced.
Description
Technical field
this utility model relates to medical surgical instrument technical field, particularly a kind of urethral probe.
Background technology
In carcinoma of prostate or bladder cancer radical operation, need to carry out rear urethra anastomosis, but because rear urethra is positioned at pelvic cavity, in urethra end to end anastomosis process, the visual field is little, and operating surface is narrow, is difficult to accurately distinguish mucous membrane of urethra while coincideing stump urethra, be difficult to carry out multiple spot accurately and coincide, sew up the less very much not easily healing of gravitation that causes coincideing of urethra outer wall tissues.
In practical operation at present, how to insert the supporter such as urethral probe or urinary catheter so that urethra is strutted at stump urethra, by the guiding of urethral probe or urinary catheter head, reach the multiple spot stitching that runs through mucous membrane of urethra and adventitia.But in practice process, have the following disadvantages: the pin that 1, coincide must tightly coordinate with urethral probe or the urinary catheter of urethra inner support, be that inserting needle exits urethral probe or urinary catheter simultaneously, but because the head of urethral probe is smooth, be difficult to accomplish accurate cooperation; Or urinary catheter adopts latex tubing and easily piercing through, thereby the pin guiding that causes coincideing is not smooth, coincide imprecise; 2, in addition, not good enough for the guiding that multiple spot is identical, easily cause matching surface dislocation and reverse; 3, repeatedly pass in and out urethral probe and easily cause injury of urethra; 4, the flat grip of traditional urethral probe end is narrower, is unfavorable for holding and rotation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of effectively guide slit zygonema turnover, improves the urethral probe of the efficiency of coincideing.
For solving the problems of the technologies described above adopted technical scheme: a kind of urethral probe of being convenient to rear urethra anastomosis guiding use, comprise probe's body, from the outwardly-bent bending section that extends to form in described probe's body one end, be interval with multiple grooves for guided anastomosis pin at described bending section outer surface, the other end of described probe's body is provided with flat grip part.
Be further used as the improvement of technical solutions of the utility model, described groove is that 4 equalizations are distributed in bending section outer surface.
Be further used as the improvement of technical solutions of the utility model, one end of each described groove extends to the top of bending section, and the other end of each described groove extends to the intersection of bending section and probe's body.
Be further used as the improvement of technical solutions of the utility model, the diameter of described probe's body is 8mm, and the degree of depth of described groove is 2 mm, and the width of described groove is 3mm, and the length of described groove is 15mm.
Beneficial effect: while utilizing this urethral probe to carry out rear urethra anastomosis operation, first urethral probe is stretched into urethra stump, the bending section of urethral probe struts urethra, and owing to being provided with multiple grooves at the spaced surface of bending section, identical pin touches groove, under the guiding function of groove smoothly into and out of completing stitching, avoid repeatedly passing in and out urethral probe damage urethra simultaneously, improve the definite rate of coincideing, avoid secondary damage, shorten operating time, reduce complication.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is described further;
Fig. 1 is the side view of this utility model embodiment;
Fig. 2 is the front view of this utility model embodiment;
Fig. 3 is the partial schematic diagram of bending section in this utility model embodiment;
Fig. 4 is the use schematic diagram of this utility model embodiment.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, a kind of urethral probe of being convenient to rear urethra anastomosis guiding use of this utility model, comprise probe's body 1, the outwardly-bent bending section 2 that extends to form from probe's body 1 one end, be interval with multiple grooves 5 for guided anastomosis pin 4 at bending section 2 outer surfaces, the other end of probe's body 1 is provided with flat grip part 3.
While utilizing this urethral probe to carry out rear urethra anastomosis operation, first urethral probe is stretched into urethra stump 6, the bending section 2 of urethral probe struts urethra, and owing to being provided with multiple grooves 5 at the spaced surface of bending section 2, the pin 4 that coincide touches groove 5, under the guiding function of groove 5 smoothly into and out of completing stitching, avoid repeatedly passing in and out urethral probe damage urethra simultaneously, improve the definite rate of coincideing, avoid secondary damage, shorten operating time, reduce complication.
In the present embodiment, groove 5 is that 4 equalizations are distributed in bending section 2 outer surfaces, wherein the diameter of whole probe's body 1 is 8mm, the degree of depth that is distributed in the groove 5 on bending section 2 is 2mm, and width is 3mm, and length is 15mm, one end of groove 5 extends to the top of bending section 2, the other end of groove 5 extends to the intersection of bending section 2 and probe's body 1, and it is smooth that urethral probe surface needs grinding process to ensure, in order to avoid damage urethra.
As preferred implementation of the present utility model, large 2 times of the flat grip of the more traditional urethral probe of flat grip part 3 volume of probe's body 1 other end, is convenient to the gripping of practical user, also the convenient anglec of rotation of holding.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but this utility model is not limited to above-mentioned embodiment, in the ken possessing at described technical field those of ordinary skill, can also under the prerequisite that does not depart from this utility model aim, make various variations.
