Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a ureteroscope with X-ray development scale. Background Art

[0002] Ureteroscopy is widely used in clinical practice. It is not only used to treat ureteral diseases, but also to explore the urethra and ureteral cavity. Ureteroscopy is a slender rigid endoscope, which consists of three parts: the main body of the tube, the eyepiece, and the body. It enters the bladder, ureter, and renal pelvis through the urethra. It has been widely used to diagnose and treat urinary tract diseases, such as urinary stones, urinary tract stenosis, and urinary tract tumors. The surgeon usually inserts the ureteroscope under direct vision. However, the ureteroscope bodies on the market currently have no marked scales, and there is no ureteroscope with scales that can be visualized under X-rays. The surgeon cannot directly judge the distance between the ureteral lesions (such as stones, tumors, etc.) and the ureteral opening.

[0003] Patent document CN213963295U discloses "a ureteroscope, wherein the ureteroscope with a light source comprises: an operating handle and a mirror body, wherein the mirror body comprises a working end and an operating end, the operating end is connected to the operating handle, the mirror body extends integrally between the working end and the operated end, and the mirror body has a discharge channel, wherein the discharge channel is used to deliver an auxiliary guide component and discharge debris.";

[0004] The above-mentioned ureteroscope lacks a structure for assisting in measuring the penetration length, so the user cannot accurately judge the penetration length, which affects the accuracy of the operation. Utility Model Content

[0005] The utility model aims to provide a ureteroscope with X-ray development scale to solve the technical problem that the sprayer in the prior art lacks a filtering structure inside, and there are too many impurities in the water, which easily causes blockage during spraying and affects the normal use of the device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ureteroscope with X-ray display scale, comprising a sheath, an objective lens is installed at one end of the sheath, an instrument channel is installed on the inner side of the sheath, a plurality of groups of X-ray display scales are installed on the outer side of the sheath, an illumination fiber is installed on the inner side of the sheath, and the illumination fiber is located on the inner side of the instrument channel, the illumination fiber is connected to the objective lens, a connecting tube assembly is installed on the other end of the sheath, the connecting tube assembly comprises a connecting tube body connected to one end of the sheath, a light guide port is installed on the top of the connecting tube body, and the inner side of the light guide port is connected to one end of the illumination fiber.

[0007] Preferably, an assembly tube is installed at one end of the connecting tube body, a connecting tube is installed at the top of the assembly tube, and an eyepiece is installed at the top of the connecting tube.

[0008] Preferably, a mounting tube is installed at one end of the assembly tube.

[0009] Preferably, assembly heads are installed on the front and back sides of the installation tube, a valve is installed at one end of the assembly head, and a flushing liquid inlet and outlet is installed at one end of the valve.

[0010] Preferably, a conduit is installed at the bottom of the installation tube, and a joint is installed at the bottom of the conduit.

[0011] Preferably, an assembly head is installed at one end of the installation tube, and an instrument connector is installed at one end of the assembly head.

[0012] Preferably, the inner side of the instrument connector is connected to one end of the instrument channel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is provided with an X-ray display scale, and the sheath 1 fixes the X-ray display scale 2 on the inner wall. The X-ray display scale 2 is composed of a molecule containing 5-iodine, N-(2,6-diiodocarboxylphenyl)-3,4,5-triiodobenzamide (DCPTB), coupled to a polymer and composed of radiopaque polyurethane, so as to ensure a smooth surface. Since the sheath has a relatively high X-ray reflection, the radiopaque polyurethane is used as a scale on the sheath to make an obvious scale shadow appear under the X-ray of the sheath, so that the scale is clearer under the X-ray. The ureteroscope with the X-ray development length scale can not only directly reflect the insertion depth of the ureteroscope, but also can directly measure the position of the ureteral lesion and the distance from the ureteral opening or the external urethra under the C-arm, so as to improve the safety of the operation and have important application value in the operation.
