[0001] This utility model relates to the field of cystoscopy technology, and in particular to a cystoscopy injection needle. Background Technology

[0002] A cystoscope is a type of endoscope that resembles a urethral probe. It consists of four parts: an electron microscope sheath, an examination endoscope, a procedure and ureteral catheterization endoscope, and a cystoscope core.

[0003] In the prior art, such as the Chinese patent publication number CN206642194U, a cystoscopic intra-injector is disclosed. It includes an endoscope, an endoscope handle, a locking nut, and an intra-injector. The endoscope handle is fixedly installed in the middle of the endoscope, and a locking nut is provided at the rear end of the endoscope. The intra-injector is installed on one side of the endoscope. The intra-injector includes an injection needle outer tube arranged parallel to the endoscope channel, an injection needle disposed in the injection needle outer tube, and a propulsion mechanism. The injection needle outer tube is installed on the outer wall of the endoscope. This utility model provides a cystoscopic intra-injector with a reasonable structural design. The injection needle can be inserted into the lesion site, and the depth of insertion can be accurately operated under direct vision. Moreover, the injection needle is fixedly connected to the main body of the operator, and the two can rotate 360° without blind spots.

[0004] While the aforementioned patent can achieve 360° rotation without blind spots, the needle tip may leak out before the cystoscope reaches the designated position, potentially causing scratches to the patient's bladder tract. Therefore, how to conceal the needle internally is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a cystoscopy injection needle that has the effect of concealing the needle tip before it reaches the designated position.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cystoscope injection needle, including a sheath connector, a connector head fixedly connected to one side of the sheath connector, an external sheath connector threaded to the external side of the connector head, an external sheath fixedly connected to one end of the external sheath connector, an internal sheath inserted into the external sheath, an injection needle head fixedly connected to the end of the sheath, multiple toothed blocks fixedly connected to the bottom of the sheath, a gear rotatably connected inside the sheath connector, the multiple toothed blocks meshing with the gear, and a rotating handle fixedly connected to the center of the gear.

[0007] By adopting the above technical solution, the sheath and injection needle extend into the interior of the outer sheath, allowing the injection needle to be concealed within the outer sheath. The outer sheath enters the patient's urethra and then into the bladder. The injection needle is not exposed when reaching the designated position through the outer sheath, effectively protecting the bladder and urethra from scratches. After the outer sheath enters the patient's bladder, twisting the rotating handle causes the gear to rotate, and multiple gears extend the sheath and injection needle, allowing the injection needle to slide out inside the outer sheath connector. Twisting the outer sheath connector causes it to move outside the connector. The movement of the outer sheath connector and the outer sheath allows the sheath and injection needle to be concealed.

[0008] A further feature of this invention is that the rotating handle extends through the outside of the sheath connector, and a protective sleeve is fixedly connected to the outside of the rotating handle.

[0009] By adopting the above technical solution, the rotating handle extends to the outside of the sheath joint, allowing the operator to rotate the rotating handle from the outside of the sheath joint.

[0010] A further feature of this invention is that the plurality of said tooth blocks are distributed along the same horizontal line.

[0011] By adopting the above technical solution, the spacing between each pair of multiple tooth blocks is equal. When the gear rotates, it contacts multiple tooth blocks, thereby driving the sheath to move.

[0012] A further feature of this invention is that a track is fixedly connected inside the sheath connector, and a slider is slidably connected inside the track.

[0013] By adopting the above technical solution, during the movement of the sheath, the slider slides inside the track, which is straight, thus achieving the effect of supporting and limiting the movement of the sheath.

[0014] A further feature of this invention is that a cavity is provided at the center of the sheath joint, and the sheath extends through the cavity to the outside of the sheath joint.

[0015] By adopting the above technical solution, the sheath extends to the outside of the sheath joint, and when the sheath moves, it enters inside the sheath joint.

[0016] A further feature of this invention is that a handle is fixedly connected to the bottom of the sheath connector, and an irregular recessed notch is provided on the outside of the handle.

[0017] By adopting the above technical solution, the device can be operated by holding the handle. The handle has multiple irregular recessed notches on its outside to improve the grip.

[0018] A further feature of this invention is that an installation groove is provided inside the outer sheath tube, and a miniature camera is fixedly installed inside the installation groove.

[0019] By adopting the above technical solution, a miniature camera is installed inside the outer sheath through a mounting slot, allowing for observation of lesions in the patient's bladder and urethra.

[0020] A further feature of this invention is that a glass layer is fixedly connected to the cross-section of the mounting groove, and a sealing ring is fixedly connected to the edge of the glass layer.

[0021] By adopting the above technical solution, the glass layer covers the cross-section of the mounting groove, and the sealing ring achieves a sealing effect.

[0022] A further feature of this invention is that the connector has a groove inside, and the inner side of the outer sheath connector is fixedly connected with a rib.

[0023] By adopting the above technical solution, when the outer sheath tube joint is connected with the connector, the rib extends into the inside of the groove, improving the tensioning effect.

[0024] A further feature of this invention is that the handle is externally fixedly connected with a lifting lug.

[0025] By adopting the above technical solution, the lifting lug is used to suspend the handle.

[0026] The beneficial effects of this utility model are:
