Abstract

The utility model discloses a urethral probe comprises a tube body with a bending portion. The urethral probe also comprises a handle for connecting the tube body, and a through hole communicated with an inner cavity of the tube body is opened at the top of the bending portion. With the handle installed and a guide hole added at the top. The urethral probe can not only ensure the accuracy of the anastomosis of the bladder and the urethra but also improve the accuracy of urinary tract reconstruction. Furthermore, the urethral probe is simple to improve, convenient for surgical operation, capable of minimizing the probability of the occurrence of surgical complications and beneficial to the spreading and popularity of radical prostatectomy.

Description

A kind of urethral probe

Technical field

This utility model relates to technical field of medical instruments, is specifically related to a kind of urethral probe.

Background technology

The bending of existing urethral probe top ends, be convenient to enter external orifice of urethra, and terminal part is flat, is convenient to the patient and grips with hands.Flat design due to terminal part, make existing urethral probe be difficult for controlling in clinical practice, patient's fatiguability etc. while keeping some tension for a long time, while particularly in art, needing urethral probe to do guiding, seem more outstanding, for example, in Laparosopic Radical Prostatectomy after urethral probe enters internal urethral orifice, need the assistant by probe's conversion direction, to the certain orientation tractive, because of the urethral probe terminal part, without handle, should not grasp for a long time, assistant's fatiguability, so greatly affected the degree of accuracy that urinary tract is rebuild.

We know, the bladder urethra anastomosis is difficult point and the emphasis in Prostate Cancer after Radical, require when guaranteeing that tumor is not residual, protect urine control structure at the bottom of the basin around anastomotic stoma as far as possible and control the neurovascular bundle of postoperative sexual function, and guarantee good coincideing.Because existing urethral probe lacks guiding, bladder and urethra anastomosis length consuming time, the incidence rate of the complication such as anastomotic stricture, leakage of urine, urinary incontinence is high, thereby has a strong impact on the recovery of urinary continence after operation in patients.

The utility model content

For overcoming above-mentioned the deficiencies in the prior art, this utility model provides a kind of urethral probe, and it,, by installing handle additional and increasing bullport on top, not only can guarantee the degree of accuracy of bladder urethra anastomosis, also can improve the degree of accuracy that urinary tract is rebuild simultaneously; In addition, urethral probe improvement of the present utility model is simple and easy, and operation technique is convenient, and the probability that can reduce to greatest extent postoperative complication occurs, and is conducive to the Popularization of Prostate Cancer after Radical.

For realizing above-mentioned purpose of the present utility model, this utility model comprises: body, and it has bending section, and the hands handle that connects body; The top of wherein said bending section offers the through hole communicated with described tube cavity.

Further, described body also has the line part be connected as a single entity with described bending section.

Preferably, described handle is cylinder, offers the hole slot be complementary with described line part termination in the middle of it, and described line part is connected with described handle by described hole slot.

Preferably, described handle is hollow.

Preferably, the length of described handle is 8～10cm.

Preferably, the Zhou Jing of described through hole is 8～10cm.

Preferably, described body and described handle are made by metal material.

Compared with prior art, the utlity model has following advantage:

1) this utility model urethral probe is offered through hole by the top at the body bending section, can in art, play good guiding function, greatly shorten the bladder urethra anastomosis time, reduced the occurrence probability of urinary extravasation and anastomotic stricture, guaranteed the degree of accuracy of bladder urethra anastomosis;

2) this utility model urethral probe, by increasing handle, makes urethral probe be convenient to grasp in operation, and the assistant can not produce fatigue yet, has greatly improved the degree of accuracy that urinary tract is rebuild;

3) urethral probe improvement of the present utility model is simple and easy, simple to operate, easy to use, but high-temperature sterilization, and Reusability, be convenient to promote.

Below in conjunction with accompanying drawing, this utility model is described in further detail.

The accompanying drawing explanation

Fig. 1 is the structural representation of this utility model urethral probe;

Fig. 2 is the structural representation of handle shown in Fig. 1.

Description of reference numerals: 1-body; The 11-bending section; The 12-line part; 2-hands handle; The 21-hole slot; The 3-through hole.

The specific embodiment

Below describe embodiment of the present utility model in detail, the example of described embodiment is shown in the drawings, can do further clear, complete explanation to this utility model.It should be noted that the embodiment that accompanying drawing is described is exemplary, only for explaining this utility model, and can not be interpreted as restriction of the present utility model.

As shown in Figure 1, urethral probe of the present utility model comprises: body 1, it has bending section 11 and line part 12, offers the through hole 3 communicated with body 1 inner chamber on the top of bending section 11, with body 1, is connected with handle 2.

Particularly, handle 2 is cylinder, offers the hole slot 21 be complementary with line part 12 terminations in the middle of it, and the termination of line part 12 can be inserted in hole slot 21, line part 12 is connected with handle 2, thereby realizes being connected of body 1 and handle 2.Handle 2 can be hollow, and such as hollow metal stick, length can be preferably 8～10cm.The all footpaths size that is arranged on the through hole 3 on body 1 bending section 11 tops can be offered according to the actual requirements, and preferred all footpaths size is 8～10cm.In addition, consider actual user demand, body 1 also can be metal tube etc.

This utility model urethral probe is for the radical operation of peritoneoscope carcinoma of prostate or bladder cancer radical operation process, when urethra reconstruction, may need to do coincideing of neck of bladder-urethra stump or new bladder-urethra stump, now can by urethral probe per urethram collar extension insert, the bending section 11 that the makes urethral probe per urethram broken ends of fractured bone enters the arthroscopic diagnosis visual field, chamber, now, and the position of definite urethra broken ends of fractured bone that the patient can be clearer and more definite, and can find more accurately urethral wall, be convenient to coincide; Simultaneously, urethral probe can be played a supporting role to the urethra broken ends of fractured bone of " softness ", and patient's operation is provided convenience.

Urethral probe of the present utility model is offered through hole 3 by the top of the bending section 11 at body 1, make urethral probe play good guiding function in art, greatly shortened the bladder urethra anastomosis time, reduced operating difficulty, reduced the occurrence probability of urinary extravasation and anastomotic stricture, guarantee the degree of accuracy of bladder urethra anastomosis, be conducive to the Popularization of Prostate Cancer after Radical; By increasing handle 2, make urethral probe be convenient to grasp in operation, the assistant can not produce fatigue yet, has greatly improved the degree of accuracy that urinary tract is rebuild; In addition, urethral probe improvement of the present utility model is simple and easy, simple to operate, easy to use, but high-temperature sterilization, Reusability, and urethral probe of the present utility model is when bringing surgical facilitation, also alleviated patient's financial burden, can extend to relevant each field of surgery and use simultaneously.
