Description

Technical Field

[0001] This utility model relates to a urethral forceps, belonging to the field of medical devices. Background Technology

[0002] Currently, the incidence of prostate cancer is increasing, and laparoscopic prostate cancer surgery is becoming more common. During surgery, it is necessary to clamp the urethra to expose it for subsequent surgical procedures. In view of this, patent application number 201921907473.4 discloses a urethral forceps for laparoscopy. However, the urethral forceps in the aforementioned prior art close by engaging a locking rack 3 with locking teeth 9 during use. This locking rack 3 and locking teeth 9 are prone to disengagement when the forceps arm is moved, affecting practicality. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the prior art and to provide a urethral forceps with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The urethral forceps includes a first forceps bar, a second forceps bar, and a hinge shaft. The first forceps bar has a first forceps head and a first finger ring at both ends, and a hinge seat in the middle. The second forceps bar has a second forceps head and a second finger ring at both ends, and a hinge block in the middle. The hinge seat and the hinge block are hinged together by the hinge shaft. Its structural feature is that the first and second forceps bars are positioned by a locking mechanism. The locking mechanism includes a locking rod, a locking hole, a insertion rod, and an insertion hole. One end of the locking rod is fixed to the first forceps bar. The locking hole is located on the second forceps bar, and the other end of the locking rod passes through the locking hole. The insertion rod is located on the second forceps bar, and the insertion hole is located on the locking rod. The insertion rod and the insertion hole cooperate with each other.

[0005] Furthermore, both the first and second pliers heads are equipped with plier teeth.

[0006] Furthermore, the jaws on the first jaw are symmetrically or staggered with the jaws on the second jaw.

[0007] Furthermore, the locking mechanism also includes a slider and a slide groove, the slide groove being disposed on the second clamp rod, the slider being located within the slide groove, and the insertion rod being fixed to the slider.

[0008] Furthermore, the locking mechanism also includes a spring, which is disposed in the slide groove, and the two ends of the spring abut against the slide groove and the slider, respectively.

[0009] Furthermore, the locking mechanism also includes a button, which is connected to the slider.

[0010] Furthermore, the locking mechanism also includes a guide rod and a guide hole. The guide rod is fixed to the slider, the guide hole is disposed on the side wall of the slide groove, the guide rod is located inside the guide hole, and a spring is fitted around the guide rod.

[0011] Furthermore, the locking rod is configured with an arc shape, and the axis of the locking rod coincides with the axis of the hinge shaft.

[0012] Compared with the prior art, the present invention has the following advantages: When the urethral forceps is locked, the spring pushes the slider, causing the slider to slide in the groove, thereby inserting the insertion rod into the insertion hole to fix the locking rod, thus achieving fixation when the first and second forceps heads are closed.

They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0024] The urethral forceps in this embodiment include a first forceps bar 1, a second forceps bar 2, and a hinge shaft 3. The first forceps bar 1 has a first forceps head 11 and a first finger ring 12 at its two ends, and a hinge seat 13 in the middle. The second forceps bar 2 has a second forceps head 21 and a second finger ring 22 at its two ends, and a hinge block 23 in the middle. The hinge seat 13 and the hinge block 23 are hinged together by the hinge shaft 3. Both the first forceps head 11 and the second forceps head 21 are provided with teeth 5. The teeth 5 on the first forceps head 11 and the teeth 5 on the second forceps head 21 are symmetrically or staggered.

[0025] In this embodiment, clamp rod 1 and clamp rod 2 are positioned by locking mechanism 4. Locking mechanism 4 includes locking rod 41, locking hole 42, insert rod 43, insertion hole 44, slider 45, slide groove 46, spring 47, button 48, guide rod 49 and guide hole 410.
