Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments and equipment, in particular to a double-locking hole prostate holmium laser enucleation mirror sheath. Background Art

[0002] Holmium laser is a new type of laser produced by a pulsed solid laser device made of laser crystal (Cr:TM:HO:YAG) with yttrium aluminum garnet (YAG) as the activation medium, doped with sensitizing ions chromium (Cr), energy transfer ions thulium (TM), and activation ions holmium (HO). It can be used in surgeries in urology, ENT, dermatology, gynecology and other departments, and is widely used in prostatectomy.

[0003] The surgical sheath currently used is a hollow cylinder with the same front and back diameter. When performing transurethral holmium laser enucleation of the prostate, the surgeon needs to use the sheath to slightly lift the prostate gland to maintain a certain tension between the gland and the prostate capsule. At this time, the blasting effect of the holmium laser is used to separate the gland from the capsule, thereby enucleating the gland. However, in actual clinical operations, due to poor angles or insufficient space, traditional sheaths often cannot fully lift the gland, resulting in insufficient tension between the gland and the capsule, and easy loss of layers. Secondly, in order to achieve the effect of fully lifting the gland, the prying is too large, resulting in damage to the external urethral sphincter and an increased risk of postoperative urinary incontinence. In addition, the head of the sheath is straight, and it is not easy to continue to separate the gland and capsule at the existing level by rotating the outer sheath, which prolongs the operation time.

[0004] To this end, those skilled in the art have proposed a double-locked hole prostate holmium laser enucleation scope sheath to solve the problems raised by the background technology. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a double-locking hole holmium laser enucleation sheath for prostate, so as to solve the problems of single sheath structure and imperfect performance of holmium laser enucleation of prostate in the prior art.

[0006] A double-locking hole holmium laser enucleation sheath for prostate comprises a sheath body, a provoking mechanism for provoking the prostate body is arranged on the outside of the body, and a locking hole mechanism is arranged on the outside of the provoking mechanism.

[0007] Preferably, the main body includes a main channel for insertion, and an extension component for improving the insertion effect of the sheath is provided inside the main channel.

[0008] Preferably, the extension assembly includes an extender and a limiting ring, the limiting ring is connected to one end of the extender, and a sliding groove for the extender to extend is provided on the inner side of the main channel.

[0009] Preferably, the provoking mechanism mainly includes a telescopic chamber for inserting the guide wire, and the insertion end of the telescopic chamber is connected to the locking hole mechanism.

[0022] As can be seen from the above, the main body 1 includes a main channel 4 for insertion of the prostate holmium laser enucleation surgery. The specific structure is a hollow cylinder with consistent front and rear diameters, wherein the provoking mechanism 2 mainly includes a telescopic chamber 8 for inserting a guide wire, and the telescopic chamber 8 is located above the main channel 4 as an integrated structure, and there is also an enucleation channel for laser entry below the main channel 4, which is also an integrated structure.

[0023] The insertion end of the telescopic bin 8 is connected to the locking hole mechanism 3, and the locking hole mechanism 3 includes a locking ring 9 and a locker 10. The main function of the locking hole mechanism 3 is to enhance the working safety of the scope sheath during the holmium laser enucleation of the prostate. The locker 10 is closed and connected to the inner side of the locking ring 9. When the button next to the locking ring 9 is pressed, the locker 10 connected to the inner side of the locking ring 9 is in an open state. At this time, the guide wire can be inserted and guided out along the insertion end of the telescopic bin 8 to lift the gland, thereby providing the staff with a better working environment for the enucleation operation. After the guide wire lifts the gland, release the button next to the locking ring 9. At this time, the locker 10 connected to the inner side of the locking ring 9 is in a closed state, which limits the guide wire to prevent the guide wire from moving and separating from the gland, thereby affecting the operating environment of the holmium laser enucleation of the prostate.

[0024] An endoscope 11 for observing the image through the sheath is also provided on the inner side of the main body 1. The endoscope 11 is located on the inner side of the insertion end of the main channel 4 and is used to better observe the internal image when the sheath is inserted, so as to facilitate the staff to perform surgical operations.

[0025] The main body 1 comprises a main channel 4 for insertion, and an extension component for improving the insertion effect of the mirror sheath is arranged inside the main channel 4.

[0026] The specific structure of the main channel 4 is a hollow cylinder with the same diameter at the front and back. The telescopic chamber 8 is located above the main channel 4, and there is also an enucleation channel for laser entry below the main channel 4. The three are an integrated structure.

[0027] The extension assembly includes an extender 5 and a limiting ring 6 . The limiting ring 6 is connected to one end of the extender 5 . A sliding groove 7 for the extender 5 to extend is provided inside the main channel 4 .

The extender 5 slides and extends in the sliding groove 7 opened in the main channel 4, thereby improving the working effect of the mirror sheath.

[0029] The provoking mechanism 2 mainly includes a telescopic chamber 8 for inserting the guide wire. The insertion end of the telescopic chamber 8 is connected to the locking hole mechanism 3. The locking hole mechanism 3 includes a locking ring 9 and a locker 10. The locker 10 is closed and connected to the inner side of the locking ring 9.

[0030] The telescopic bin 8 is located above the main channel 4, and the locking hole mechanism 3 includes a locking ring 9 and a locker 10. The main function of the locking hole mechanism 3 is to enhance the working safety of the scope sheath during the holmium laser enucleation of the prostate. The locker 10 is closed and connected to the inner side of the locking ring 9. When the button next to the locking ring 9 is pressed, the locker 10 connected to the inner side of the locking ring 9 is in an open state. At this time, the guide wire can be inserted and guided out along the insertion end of the telescopic bin 8 to lift the gland, thereby providing a better working environment for the enucleation operation for the staff. After the guide wire lifts the gland, release the button next to the locking ring 9. At this time, the locker 10 connected to the inner side of the locking ring 9 is in a closed state, which limits the guide wire and prevents the guide wire from moving and separating from the gland.

[0031] An inner mirror 11 is also provided on the inner side of the main body 1 for observing the image through the mirror sheath.

[0032] The endoscope 11 is used to better observe the internal scene when the endoscope sheath is inserted, so as to facilitate the staff to perform the surgical operation.
