Technical Field

[0001] The invention relates to the technical field of urethral caruncle electric cutters, in particular to a urethral caruncle electric cutter. Background Art

[0002] Compared with the male urethra, the female urethra is very short. During urethral caruncle surgery, the female urethral caruncle is mostly located at the external orifice of the female urethra or slightly inside, and physiological saline is easy to flow out of the urethra. In order to extend the female urethra, the existing technology uses a syringe extension tube to be sleeved on the outer sheath, artificially extend the urethra, and achieve blockage through the elliptical base on the syringe extension tube to prevent physiological saline from leaking from the urethra. However, the elliptical base cannot be deformed, and the urethral caruncle electric cutter needs to constantly adjust its position during operation, which results in the elliptical base being unable to completely seal the urethral orifice. Under the action of pressure, some physiological saline will still flow down, and the physiological saline in the urethra cannot achieve the purpose of dilating the urethra. The caruncle is easy to contact the inner wall of the urethra, and the inner wall of the urethra affects the action of cutting the caruncle during cutting. Summary of the invention

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the prior art, such as the publication (announcement) number: CN204995432U, the urethral caruncle electrotomy adopts an elliptical base to cover the urethra, but the elliptical base cannot be deformed, and the urethral caruncle electrotomy knife needs to constantly adjust its position during operation. The elliptical base will rotate simultaneously with the connecting sleeve, and the elliptical base cannot completely seal the urethral opening. Part of the saline does not flow out from the upper outlet, but directly flows down from the gap, resulting in insufficient saline to support the urethra. The urethra has a contraction function, and a small amount of saline cannot expand the urethra, which causes the urethra to contract and contact with the caruncle, resulting in contact with the inner walls on both sides of the urethra during cutting, causing multiple injuries to the inner wall of the urethra. Example 1: Reference Figure 1-Figure 5 A urethral caruncle electric cutter comprises an outer sheath 1, an inner sheath tube 2, a cutter body 3, a handle 4 and an endoscope 8, wherein the inner sheath tube 2 is inserted from one side of the handle 4, and the endoscope 8 is inserted from the other side of the handle 4 and extends into the inner sheath tube 2, the outer sheath 1 is sleeved on the inner sheath tube 2 and connected to the handle 4, the cutter body 3 is mounted on the handle 4 and extends into a water flow channel formed between the outer sheath 1 and the inner sheath tube 2, a urethral extension component 5 is sleeved on the outer sheath 1, and a leak-proof component 6 is arranged on the urethral extension component 5; The urethral extension component 5 and the anti-leakage component 6 are sleeved on the outer sheath 1, a part of the outer sheath 1 is inserted into the urethra, a lower flushing tube 11 is provided at the bottom of the outer sheath 1, and an upper flushing tube 12 is provided at the top, physiological saline flows into the outer sheath 1 from the lower flushing tube 11, and then flows out from the upper flushing tube 12, and valves are provided on the lower flushing tube 11 and the upper flushing tube 12, and the urethral extension component 5 is outside the urethra, which is used to solve the problem of a short female urethra. The physiological saline can flow into the urethral extension component 5 from the water flow channel, and the physiological saline in the anti-leakage component 6 flows away from between the outer sheath 1 and the urethral extension component 5.

[0020] The urethra extension assembly 5 includes a sleeve 51, a front half ring 52 and a rear half ring 53. The inner circumference of the sleeve 51 is fixed with staggered front half rings 52 and rear half rings 53. The outer sheath 1 passes through the sleeve 51 and contacts with the inner circumferences of the front half ring 52 and the rear half ring 53. The end faces of the front half ring 52 and the rear half ring 53 are flush, and the inner circumference edges of the front half ring 52 and the rear half ring 53 are processed with rounded corners.

[0021] The sleeve 51 is made of a transparent material, and the positions of the front half ring 52 and the rear half ring 53 inside the sleeve 51 can be seen. During use and assembly, when the outer sheath 1 is inserted into the sleeve 51, the transparent sleeve 51 can be seen to the extent that the outer sheath 1 is inserted into the sleeve 51. The staggered front half ring 52 and the rear half ring 53 are used to support both sides of the outer sheath 1, and the rounded corner process is used to facilitate the insertion of the outer sheath 1. At the same time, the staggered front half ring 52 and the rear half ring 53 do not affect the flow of saline into the sleeve 51, that is, they serve the purpose of support without shortening the volume of the sleeve 51 to accommodate saline.

[0022] The leakage prevention component 6 includes a sealing ring 61 and a urethral covering member 62. The urethral covering member 62 engages with a threaded port on one side of the sleeve 51, and the sealing ring 61 is arranged on a non-threaded port on the other side of the sleeve 51. A sealing gasket is fixed on the inner circumferential surface of the sealing ring 61, and the outer sheath 1 passes through the sealing ring 61 and is wrapped by the sealing gasket.

[0023] The sealing ring 61 seals the sleeve 51 and the outer sheath 1. The sealing ring 61 is made of hard material, and the sealing gasket is made of rubber. The inner diameter of the sealing gasket is smaller than the outer diameter of the outer sheath 1. After the outer sheath 1 passes through the sealing ring 61, the sealing gasket is squeezed, which can not only maintain the sealing of the connection but also limit the movement of the sleeve 51 through friction, avoiding the problem that the sleeve 51 slides along the outer sheath 1 under a smaller thrust.

[0024] The urethral covering member 62 includes a hard ring 621, a retaining ring 622 and a urethral horn covering opening 623. An inwardly concave annular groove 6231 is provided at the port of the urethral horn covering opening 623. The retaining rings 622 and external threads are fixed in parallel on the outer peripheral surface of the hard ring 621. The side peripheral surface of the hard ring 621 is connected to the urethral horn covering opening 623 on one side of the annular groove 6231. The edge of the port on the other side of the urethral horn covering opening 623 is turned outward. When the urethral horn covering opening 623 fits the skin near the urethra, the turned-out structure increases the contact area with the skin under the action of pressure, so as to cover the urethral opening.

[0025] The hard ring 621 is screwed into the sleeve 51 , the internal thread and the external thread are meshed, and the port of the sleeve 51 contacts the sealing ring on the side circumference of the retaining ring 622 .

[0026] The sleeve 51 is connected to the hard ring 621 by means of threads, so as to facilitate the assembly and disassembly of the above structure for replacement. After the sleeve 51 and the hard ring 621 are assembled, the end of the sleeve 51 will abut against the sealing ring to maintain the sealing of the connection.

[0027] The urethral horn covering opening 623 is in the shape of a horn, with the end with a small diameter connected to the sleeve 51, and the end with a large diameter used to cover the urethral opening, and the urethral horn covering opening 623 is made of medical silicone, which is a kind of synthetic rubber. Since rubber itself has the ability to deform, it can conform to the skin through its own deformation according to different body structures. At the same time, when the urethral caruncle electrosurgical cutter changes its position during operation, the urethral horn covering opening 623 can still be deformed to maintain the purpose of covering the urethral opening.

[0028] When in use, after the sleeve 51 is screwed onto the hard ring 621, the outer sheath 1 is inserted from the sealing ring 61 and through the sleeve 51, and the positions of the outer sheath 1 and the urethral horn covering opening 623 are adjusted as needed, and the end with a larger diameter of the urethral horn covering opening 623 is attached to the skin near the urethra, such as Figure 3As shown, the lower flushing tube 11 draws saline solution and flows into the outer sheath 1 through the lower flushing tube 11. The lower flushing tube 11 and the upper flushing tube 12 are staggered. The inner wall of the outer sheath 1 first blocks the saline solution flowing into the lower flushing tube 11, and the saline solution flows along the two ends of the outer sheath 1. Then, since the port of the outer sheath 1 is in the position for inserting into the urethra, and the upper flushing tube 12 is used to discharge the saline solution of the outer sheath 1, the saline solution flowing toward the urethral horn covering port 623 will push the saline solution originally located in the urethral horn covering port 623 to flow toward the upper flushing tube 12. The valve of the upper flushing tube 12 is in an open state, and the saline solution slowly overflows into the upper flushing tube 12. The saline solution is discharged along with the upper flushing tube 12, and the delivered saline solution flows into the urethra along the outer sheath 1, and then flows from the urethra to the upper flushing tube 12, completing the saline flushing cycle, maintaining the purpose of urethral dilation and enlargement, and the saline solution will not leak out, keeping the saline temperature in the urethra at an appropriate temperature at all times.

[0029] Example 2: Reference Figure 6-Figure 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment. In order to solve the problem that the elliptical base cannot completely seal the urethral opening, a round silicone cover is placed on the port of the test tube. Since the medical rubber can be deformed; If medical rubber with a lower hardness is used, it will not have enough hardness to fit the skin. When physiological saline flows into the urethral horn covering opening 623, the water pressure will squeeze the gap between the urethral horn covering opening 623 and the skin, causing the physiological saline to flow down from the gap between the urethral horn covering opening 623 and the skin.

[0030] If a medical rubber with a relatively high hardness is used to ensure that the urethral horn cover opening 623 has sufficient support and fit with the skin, and the medical rubber has a relatively large thickness, the deformation ability is relatively poor, and like the elliptical base of the first embodiment, it will move synchronously when the electric cutter is working, resulting in failure to completely seal the urethra.

[0031] The leakage prevention component 6 also includes a support portion 63, which is sleeved on the outside of the urethra covering component 62. The support portion 63 provides support for the urethra covering component 62. The support portion 63 includes a circular ring 631 that is stuck in the annular groove 6231 of the urethra horn covering opening 623. A number of telescopic parts are distributed on the circular ring 631, and the circular ring 631 is connected to the adapter ring 632 through the telescopic parts.

[0032] The support portion 63 can be removed from the urethra covering part 62, and the support portion 63 can be reused to reduce costs. During assembly, the circular ring 631 of the support portion 63 is assembled from a portion of the urethra horn covering opening 623 where the diameter is large. The urethra horn covering opening 623 is pinched to be smaller and then inserted into the circular ring 631. The circular ring 631 is inserted into the ring groove 6231. The urethra horn covering opening 623 is released and restored under the action of elastic force. The adapter ring 632 is adjusted to the eversion of the urethra horn covering opening 623.

[0033] The support portion 63 is used to support the urethral horn covering opening 623 to prevent the urethral horn covering opening 623 from being deformed excessively when squeezed by external force, thereby causing leakage, so as to ensure that the urethral horn covering opening 623 can be closely attached to the skin near the urethral opening. The adapter ring 632 is used to press down the eversion of the urethral horn covering opening 623.

[0034] The telescopic component includes an outer tube 633, an inner rod 634, a sleeve 635, a buckle 636 and a connecting shaft 637. One end of the outer tube 633 is fixed to a lock sleeve 638 through a ball hinge, wherein the lock sleeve 638 is fixed on the ring 631, one end of the inner rod 634 is inserted into the opening of the other end of the outer tube 633 and connected to the outer tube 633 through a spring, the other end of the inner rod 634 is fixed with a sleeve 635, one end of the connecting shaft 637 is inserted into the sleeve 635 for rotation, the other end of the connecting shaft 637 is fixed to the outer wall of the buckle 636, and the buckle 636 is buckled on the adapter ring 632; The adapter ring 632 rests against the everted urethral horn covering opening 623 , and the outer tube 633 and the inner rod 634 are used to support the outer circumference of the urethral horn covering opening 623 .

[0035] Since the locking sleeve 638 is fixed on the ring 631, the outer tube 633 and the locking sleeve 638 are connected by a ball hinge, the outer tube 633 can be adjusted in a wide angle range, and the inner rod 634 can be extended and retracted in the outer tube 633, and the inner rod 634 is fixed by an internal spring. The movement of the inner rod 634 in the outer tube 633 is affected by elastic force, and the support part 63 is sleeved on the urethral horn covering opening 623. Then, in the initial state, the inner rod 634 and the outer tube 633 drive the adapter ring 632 to press against the everted urethral horn covering opening 623; The connecting shaft 637 can rotate around the sleeve opening 635, and the buckle 636 is buckled on the adapter ring 632 and can also rotate around the adapter ring 632. After the adapter ring 632 presses against the urethral horn covering opening 623 to cover the urethral opening, the rotation angle and direction of the ring 631 can be translated or rotated in a small range through the support of the above structure, and the urethral horn covering opening 623 always fits the skin at the urethral opening to prevent saline from flowing out from the gap between the urethral horn covering opening 623 and the skin.

[0036] The technical solution realizes multi-angle adjustment by setting a telescopic component, and the telescopic component can also serve the purpose of support. When the electric cutter is adjusted to a certain angle, the telescopic component at the corresponding angle has the largest telescopic range, while the telescopic components at other angles have smaller telescopic ranges. During the operation, the urethral horn covering port 623 can always cover the urethral opening. During the operation, the physiological saline injected from the lower inlet flows into the urethra, and the urethra is completely covered by the urethral horn covering port 623. The physiological saline expands the urethra and then slowly overflows and flows out from the upper outlet. With the continuous inflow and outflow of the physiological saline, the urethra is always kept in an expanded state, producing a magnifying glass effect and separating the inner wall of the urethra from the caruncle. When cutting, only the connection between the caruncle and the inner wall of the urethra is removed to avoid the contact between the cutter and the inner walls of the urethra on both sides, causing multiple injuries.

[0037] Example 3: Reference Figure 9-11 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment. In the prior art, the caruncle removal surgery cannot be completely removed at one time. Therefore, when removing the caruncle, it is necessary to continuously remove the removed caruncle from the urethra to prevent the removed caruncle from blocking the field of vision in the urethra and affecting the subsequent removal action. A caruncle storage assembly 7 is also fixed on the inner wall of the hard ring 621. The caruncle storage assembly 7 includes a storage arc plate 71 and a connecting plate 72. The pipe openings of the outer sheath 1 and the storage arc plate 71 are both set with oblique openings. The storage arc plate 71 and the oblique openings of the storage arc plate 71 are cross-set. The storage arc plate 71 and the outward port of the outer sheath 1 are flush. The other port of the storage arc plate 71 facing the inside of the outer sheath 1 is fixed to the inner circumferential surface of the hard ring 621 through the connecting plate 72. The storage arc plate 71 is located directly below the outer sheath 1.

[0038] The cutter body 3 slides along the guide block at the bottom of the inner sheath tube 2 , and an arc plate 711 is fixed on the other edge of the arc plate 71 symmetrical to the bevel, and a raised retaining edge is fixed on the bevel edge of the arc plate 71 .

[0039] The outer sheath 1 is provided with diverter holes, the inner circumference of the arc plate 711 is against the outer circumference of the outer sheath 1 , and the arc plate 711 is located between the oblique opening of the outer sheath 1 and the diverter holes.

[0040] The caruncle storage assembly 7 is used to temporarily store the caruncle cut by the cutter body 3, so there is no need to constantly pull the outer sheath 1 out of the urethra to take out the cut caruncle, which affects the surgical process; The lens of the endoscope 8 is located in the inner sheath tube 2, and the outer sheath 1 and the inner sheath tube 2 are both arranged with an oblique mouth, so that the endoscope 8 can see the working process of the cutter body 3. The storage arc plate 71 is arranged with an oblique mouth, and the edge forms a barrier structure through the raised retaining edge and the arc plate 711. The cut caruncle is pushed back by the cutter body 3 and falls into the storage arc plate 71, and the height of the retaining edge does not affect the reciprocating movement of the cutter body 3. Since the water flow channel continuously flows into the water flow channel from the lower flushing pipe, the saline solution passes through the diversion hole and then flows toward the urethra, and is blocked by the arc plate 71, so that the saline solution bypasses the arc plate 711 and does not directly act on the caruncle on the storage arc plate 71, so as to avoid washing the caruncle away from the storage arc plate 71.

[0041] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
