[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0035] The present embodiment provides a superfine caliber laser resectoscope, which only includes a rod body 1, an electronic flexible scope 2, a laser fiber pipeline 3, an operator 4 and a joint 5. Obviously, compared with a conventional resectoscope, the laser resectoscope first removes the design of an outer sheath, which can at least reduce the caliber of the resectoscope by 2 Fr units. For example, Figure 1 and Figure 2As shown, the rod body 1 is provided with two through holes along the length direction thereof. In order to ensure that the rod body 1 has sufficient supporting force and strength, the diameter of one through hole is the same as the diameter of the electronic flexible scope 2, and the electronic flexible scope 2 is arranged to pass through the through hole; the diameter of the other through hole is the same as the diameter of the laser fiber pipeline 3, and the laser fiber pipeline 3 is arranged to pass through the through hole. The rod body 1 is equivalent to the inner sheath in the conventional laser resection mirror. The arrangement of the through holes makes the other parts of the rod body 1 in a solid state except the through holes, which can significantly enhance the supporting force and strength of the rod body 1 compared with the pipe body used in the conventional inner sheath. In addition, the rod body 1 can be made of stainless steel, titanium alloy or the like, which can further improve the strength of the rod body 1 and has good biocompatibility.

[0036] The electronic flexible scope 2 can be directly used as an existing electronic flexible scope 2, which generally includes an insertion part, a front end part, a bending part, an operating part and the like. In order to observe the complex environment in the human body, the bending part of the existing electronic flexible scope 2 can be bent. The electronic flexible scope 2 applied in the present design can be further optimized. Since the bending related structure design is not required, the electronic flexible scope 2 applied in the present design can further remove some irrelevant structures, such as the bending function. Only the necessary shooting and lighting functions are retained, so that the diameter of the electronic flexible scope 2 can be further reduced, and thus the overall caliber of the laser resection mirror can be reduced. In one embodiment, since the electronic flexible scope 2 does not need the bending function and the like, the operating part of the electronic flexible scope 2 is directly integrated on a small display screen 12. Please refer to Figure 3 The operating device 4 is provided with a magnetic base which is detachably connected with the display screen 12. The display screen 12 can be directly adsorbed on the magnetic base during the operation process, and is used to display the picture shot by the electronic flexible scope 2, so that the operator can easily and intuitively observe the situation at the front end of the laser resection mirror, which reduces the complexity of the operation, facilitates the operator to perform the operation, and improves the operation efficiency, so as to be beneficial to carry out the day surgery and even carry out the outpatient small operation. In another embodiment, the rear end of the electronic flexible scope 2 arranged in the rod body 1 is connected with a data line, which is used to transmit the picture signal shot by the electronic flexible scope 2 to the display device at the rear end through the data line. The display device specially used for connecting the electronic flexible scope 2 is large in size, and is not suitable to be installed on the operating device 4, but the picture displayed by the display device is large in size and clear, which is beneficial to clearly observe the picture shot by the electronic flexible scope 2.

[0037] The operating device 4 is arranged at one end of the rod body 1, that is, the operating device 4 is at the end of the rod body 1 outside the human body during the operation process, and is used to control the laser fiber pipeline 3 to stretch and retract in the through hole. As shown in Figure 3As shown, the operator 4 includes a connecting tube, a handle, a slider, a reset assembly and the like. The length of the conventional connecting tube is generally equivalent to the length of the laser fiber tube 3, which needs to be inserted into the inner sheath together with the laser fiber tube 3. Its function is to limit the position of the laser fiber tube 3 through the limiting structure to prevent the laser fiber tube 3 from deviating during the extension and retraction process. Due to the special design of the rod body 1 in this design, the connecting tube can be designed to be very short, and a small part of it is inserted into one of the through holes, so that the operator 4 can be connected with the rod body 1. The part of the connecting tube inserted into the rod body 1 will inevitably be thickened, but this thickened part will not be inserted into the human body. The laser fiber tube 3 is inserted into the other through hole, and the through hole is used to limit the laser fiber tube 3, so that a long connecting tube is not needed. Therefore, compared with the conventional laser resection mirror, the aperture increase caused by the thickness of the connecting tube can be reduced. The electronic flexible scope 2 enters the through hole by passing through the connecting tube. The slider is slidingly arranged on the outside of the connecting tube. The handle is connected with the slider and is used to drive the slider to slide on the connecting tube. At the same time, the slider is fixed with the laser fiber tube 3. The reset assembly generally includes a spring. Through the elasticity of the spring and the pressing of the handle by the operator, the slider can move back and forth, thereby driving the laser fiber tube 3 to extend and retract in the through hole, and realizing the laser resection of the lesion site. In the prior art, the function of the laser fiber tube 3 is only to pass the optical fiber. One end of the optical fiber is connected with the light source, and the other end extends to the end of the laser fiber tube 3 located in the human body, and the laser energy is transmitted through the optical fiber. The circulating water system is necessary for the laser resection mirror, and is also an important factor limiting the aperture of the resection mirror. In the existing design of the laser resection mirror, the water injection is through the space inside the inner sheath, and the water drainage is through the space between the inner sheath and the outer sheath, which is a very mature scheme and has been used for a long time. The present scheme creatively combines the optical fiber channel with the water injection function to replace the water injection channel of the traditional resection mirror. The optical fiber channel water injection and the stoma tube backwater form a complete water circulation, breaking the thinking inertia of the traditional resection mirror design (i.e. simply reducing the aperture by reducing the precision and the thickness of the sheath), which can reduce the aperture of the laser resection mirror (through a series of designs described above, the aperture of the laser resection mirror can even reach Fr6~Fr18) while not reducing the original functions, and the resection mirror still has strong support and strength as a whole.

[0038] Specifically, the structure design of the optical fiber channel combined with the water injection function in the present embodiment is as follows Figure 4The special designed joint 5 is arranged at the end of the laser fiber conduit 3 close to the operator 4. The joint 5 includes a tee pipe 6, a hose 7 and a lock. One end of the tee pipe 6 is communicated with the laser fiber conduit 3. In this embodiment, the tee pipe 6 is detachably connected with the end of the laser fiber conduit 3, and the connection is usually in the form of screw thread, so that the connection can be quickly detached and installed. The other end of the tee pipe 6 is used to communicate with an external water source. A valve can be installed on the end connected with the external water source, for controlling the opening and closing of the water inlet. It is worth mentioning that, in order to ensure sufficient water inflow, the external water source can be arranged as a pressurized water source. The water after being pressurized is filled into the human body through the joint 5 and the laser fiber conduit 3, so as to ensure sufficient water inflow. The remaining end of the tee pipe 6 is communicated with the hose 7. The optical fiber is usually inserted into the laser fiber conduit 3 before the operation, and in order to ensure the smooth installation of the optical fiber, the hose 7 is preferably arranged coaxially with the laser fiber conduit 3. In order to avoid the water filled into the laser fiber conduit 3 from flowing out from the rear end of the laser fiber conduit 3 (i.e. the end close to the operator 4), the lock needs to be used in cooperation with the hose 7. In this embodiment, the lock includes an insert 8 and two threadedly connected collars 9. The insert 8 is annular and sleeved on the hose 7, and a bevel is arranged on one end of the outer wall of the insert 8. The insert 8 itself has a certain elasticity, and a notch is formed in the annular insert 8, so that the insert 8 can be deformed more easily. One of the collars 9 is fixedly sleeved on the tee pipe 6, and the other collar 9 is sleeved on the insert 8, and the inner wall thereof abuts against the bevel on the insert 8. When the collar 9 sleeved on the insert 8 is rotated, the two collars 9 are away from or close to each other due to the thread effect, so that the inner wall of the collar 9 extrudes the bevel on the insert 8 and deforms the insert 8 towards the hose 7. The deformation of the insert 8 extrudes the hose 7, so that the hose 7 is tightly sealed with the periphery of the optical fiber, thereby preventing the water from flowing out from the rear side of the laser fiber conduit 3. This design not only solves the problem of water flowing out from the rear side of the laser fiber conduit 3, but also can fix the optical fiber in the laser fiber conduit 3. Specifically, the operator 4 is used to reciprocatingly drive the laser fiber conduit 3 to stretch and retract in the inner sheath, and the laser fiber conduit 3 in this scheme needs to be filled with water at the same time. Thus, in the process of repeated movement of the laser fiber conduit 3, the optical fiber in the laser fiber conduit 3 can easily slide relative to the laser fiber conduit 3, which affects the laser cutting of the front end of the laser fiber conduit 3. The lock designed in this embodiment can lock or clamp the optical fiber at the end of the laser fiber conduit 3 through the hose 7, so as to prevent the optical fiber from sliding relative to the laser fiber conduit 3.

[0039] In another embodiment, compared with the above-mentioned embodiments, the joint 5 can be directly provided as a tee pipe 6. One end of the tee pipe 6 is communicated with the laser fiber pipe 3, the other end is used to communicate with an external water source, and the remaining end is used to pass the optical fiber into the laser fiber pipe 3. Such a design can reduce the structural design of the rear end of the laser fiber pipe 3 and facilitate operation. As for the water leakage problem of the rear end of the laser fiber pipe 3, sealing methods such as wrapping the optical fiber and the laser fiber pipe 3 with sealing tape, filling sealing material between the optical fiber and the laser fiber pipe 3, etc. can be used, which are not listed here.

[0040] In another embodiment, an ultra-fine caliber laser resection mirror combined kit is also provided, which comprises the ultra-fine caliber laser resection mirror and a stoma tube as described above. The stoma tube is used to drain the water injected through the laser fiber pipe 3 from the human body. The water drainage function of the traditional prostate resection mirror using the water outlet channel between the inner and outer sheaths is realized by the stoma tube in this embodiment, which is the premise that the above-mentioned laser resection mirror can be implemented. The caliber of the stoma tube can be freely designed to meet the water outlet requirements in any transurethral surgery. The stoma tube can use the existing stoma tube or the stoma tube in this embodiment. The stoma tube in this embodiment is used in cooperation with a corresponding top core rod. One end of the stoma tube can be elastically changed. The top core rod is used to extend into the stoma tube and change the shape of the elastic end of the stoma tube. Specifically, as shown in Figure 5 the stoma tube comprises a hard pipe 10 and an elastic sleeve 11. One end of the elastic sleeve 11 is fixedly communicated with the hard pipe 10, and the other end is a closed part. A plurality of filter holes are also provided on the elastic sleeve 11. The shape of the elastic sleeve 11 can be elastically changed. That is, the elastic sleeve 11 is deformed under the action of an external force. The top core rod can be inserted into the stoma tube, contacted with the elastic sleeve 11, and stretched to change the elastic sleeve 11 into a conical shape, so as to facilitate the insertion of the stoma tube into the puncture hole in the patient's abdomen. When the elastic sleeve 11 extends into the patient's body, the top core rod can be withdrawn. When the external force is removed, the elastic sleeve 11 can restore to its original shape and size. The initial shape of the elastic sleeve 11 before elastic change can be set as a flat balloon, as shown in Figure 6 the elastic sleeve 11 is located in the patient's bladder during use, and the diameter of the elastic sleeve 11 restored to the initial shape is greater than the diameter of the puncture hole, thereby preventing the stoma tube from falling off from the puncture hole in the patient's abdomen, and the end of the stoma tube can be externally connected with a pipe to drain water. The main part of the top core rod is a straight rod, which needs a certain strength to stretch the elastic sleeve 11. At the same time, the end of the top core rod is rounded to prevent it from piercing the elastic sleeve 11.

[0041] In summary, the traditional prostate laser resectoscope only reduces the total caliber by reducing the thickness and diameter of the constituent parts. The total caliber is reduced limitedly, and the overall support of the resectoscope is prone to be reduced, and the resectoscope is prone to be deformed or even broken, and there are limitations. The ultra-fine caliber urethral resectoscope and the combined kit thereof proposed by the utility model change the overall design idea, propose a brand-new laser resectoscope structure which can maintain the original function of the resectoscope and reduce the caliber. The outer sheath is innovatively removed, and a fistulization assembly is designed to build a stable water inlet and outlet system. At the same time, the inner sheath is used as the outermost layer of the entire new laser resectoscope structure, the electronic flexible scope 2 is used to replace the traditional hard eyepiece, and the caliber of the resectoscope extending into the urethra can reach Fr6-Fr18, so that the required ultra-fine caliber is realized. The laser resectoscope proposed by the utility model is improved by a brand-new structure, and components with sufficient support and strength on the market can be selected, instead of reducing the caliber by reducing the thickness and diameter of the constituent parts on the basis of the unchanged existing laser resectoscope structure, so that the caliber of the laser resectoscope can be reduced while the support and strength of the mirror body are still sufficient, and the mirror body is not prone to deformation and breakage.

[0042] In another embodiment, a use method of the ultra-fine caliber laser resectoscope combined kit is also proposed, which uses the ultra-fine caliber laser resectoscope combined kit as described above. The use method comprises the following steps:

[0043] The external irrigation water enters the human body through the joint 5 and the laser fiber pipeline 3; and the irrigation water in the human body is discharged from the human body through the fistulization tube, so as to form a dynamic circulation of the irrigation water.

[0044] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the description.

[0045] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
