Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a fiber optic implant for laser surgery and a laser surgery apparatus. Background Technology

[0002] Laser surgery is a surgical method that utilizes the highly concentrated energy of laser light. A fiber optic guide serves as the carrier for introducing the laser fiber into the patient's body. The fiber passes through an internal channel of the guide and protrudes from its tip. The surgeon manipulates the guide to insert the fiber optic cable into the patient's body, using the laser to perform surgical procedures on the lesion. However, during actual laser surgery, a large amount of smoke and eschar are generated. This smoke can affect the surgical field of vision, pollute the environment, and harm the health of the surgical personnel.

[0003] In existing technology, the surgical wound is cleaned by spraying saline solution, which also dissolves the generated fumes and prevents them from spreading. However, there is no water injection valve on the saline solution irrigation channel to control the flow rate. The existing water injection valve is far from the applicator and is usually operated by nurses following the doctor's instructions. This not only increases the number of staff required, but also makes it difficult to open or close the water injection valve in a timely manner. Summary of the Invention

[0004] The purpose of this invention is to provide a fiber optic inlet for laser surgery, which allows doctors to open or close the water inlet valve in a timely manner according to actual needs, reducing the number of personnel required for surgical procedures.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A fiber optic implant for laser surgery includes an inner tube and an outer tube assembly sleeved outside the inner tube. A water spray hole is provided at a first end of the outer tube assembly. A water injection cavity is formed between the inner tube and the outer tube assembly. The outer tube assembly has a water inlet communicating with the water injection cavity. The device also includes:

[0007] The water injection valve has an outlet pipe connected to the outer pipe assembly to connect the outlet pipe to the water injection port. The water injection valve is equipped with an exposed manual switch for connecting or disconnecting the inlet pipe and the outlet pipe.

[0008] Preferably, the outer pipe assembly includes an outer pipe with the water inlet and a sealing pipe fitting sleeved on the outer pipe and sealed to the outer pipe to form a connecting cavity. The water outlet pipe is inserted into the sealing pipe fitting and communicates with the water inlet through the connecting cavity.

[0009] Preferably, the sealing fitting includes:

[0010] A front sealing fitting is provided with a positioning element on the outer wall of the outer pipe. The front sealing fitting is sleeved on the outer wall of the outer pipe, and one end of the front sealing fitting is fixed to the outer wall of the outer pipe through the positioning element. A rear sealing fitting is sealed to the other end of the front sealing fitting. The rear sealing fitting includes an upper sealing fitting and a lower sealing fitting. The upper sealing fitting is sleeved on the water outlet pipe and seals with the water outlet pipe. The lower sealing fitting is sleeved on the outer pipe.

[0011] Preferably, the positioning member has a protrusion and the front sealing tube has a groove, and the protrusion is inserted into the groove.

[0012] Preferably, the laser surgery fiber optic introducer further includes a first sealing plug, which is sandwiched between the sealing tube and the outer tube, and the front end of the sealing plug abuts against the positioning member.

[0013] Preferably, the fiber optic implant for laser surgery further includes a second sealing plug, which is a stepped tubular shape. A portion of the second sealing plug is sandwiched between the outer tube and the inner tube, and the other portion is covered by the lower sealing tube. The rear end of the middle step of the second sealing plug abuts against the rear end of the lower sealing tube.

[0014] Preferably, the laser surgical fiber optic introducer further includes a third sealing plug, which is sandwiched between the upper sealing tube and the water outlet tube.

[0015] Preferably, the angle between the water flow direction in the outlet pipe and the water flow direction in the injection chamber is an acute angle.

[0016] Preferably, the water injection valve is a flow regulating valve.

[0017] Preferably, the fiber optic implant for laser surgery further includes a housing, with the end of the outer tube assembly without the water spray hole placed inside the housing, and the end of the outer tube assembly with the water spray hole extending out of the housing.

[0018] Preferably, the housing includes a front handle housing and a rear handle housing, and the front handle housing and the rear handle housing are detachably connected.

[0019] Preferably, the outer wall of the front shell of the handle is provided with an anti-slip layer.

[0020] Preferably, the inner tube is used to insert the optical fiber, and one end of the housing is connected to a locking part. The locking part includes at least two circumferentially arranged claws that form a through hole. The claws are capable of elastic deformation. One end of the optical fiber passes through the inner tube, the housing, and the through hole in sequence.

[0039] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides a fiber optic introducer for laser surgery and a laser surgery device, wherein the laser surgery device includes the aforementioned fiber optic introducer for laser surgery.

[0041] The aforementioned fiber optic implant for laser surgery includes an inner tube 1, an outer tube assembly 2 sleeved outside the inner tube 1, and a water injection valve 3. The first end of the outer tube assembly 2 has a water spray hole 211. A water injection cavity is formed between the inner tube 1 and the outer tube assembly 2. The outer tube assembly 2 has a water injection port 212 communicating with the water injection cavity. The water outlet pipe 32 of the water injection valve 3 is connected to the outer tube assembly 2 so that the water outlet pipe 32 communicates with the water injection port 212. The water injection valve 3 has an exposed manual switch 31 for connecting or disconnecting the water inlet pipe 33 and the water outlet pipe 32. In this embodiment, the end of the water inlet pipe 33 has pagoda-shaped barbs for easy installation and fixing of the water inlet hose.

[0042] The fiber optic implant for laser surgery provided in this embodiment directly connects the outlet pipe 32 of the water injection valve 3 to the outer tube assembly 2, so that the outlet pipe 32 is connected to the water injection port 212. The manual switch 31 of the water injection valve 3 is exposed, so that the water injection valve 3 is directly set on the fiber optic implant. This allows doctors to close the water injection valve 3 in a timely manner to stop the implant from spraying saline, or to open the water injection valve 3 in a timely manner to allow the implant to spray saline, without the need for a dedicated nurse to operate the water injection valve 3. The operation is convenient and quick, effectively improving work efficiency.

[0043] Furthermore, such as Figure 2 As shown, the angle between the water flow direction in the outlet pipe 32 and the water flow direction in the injection chamber is an acute angle, which facilitates spraying. Simultaneously, setting it to an acute angle helps reduce the impact of the inlet pipe 33 on the handle grip and operation after connection. In this embodiment, direction B indicates the direction of the water injection channel, and direction C indicates the direction of water flow in the injection chamber. The first end of the outer pipe assembly 2 has a conical structure with multiple spray holes 211 distributed in a circumferential square pattern. Due to the conical structure at the first end, the water flow direction from the spray holes 211 forms different angles. When water flows from the outlet pipe 32 into the injection chamber, the water flows through the injection chamber and is sprayed out from the spray holes 211, which can clean the wound surface after laser cutting. Simultaneously, the water sprayed from the side can dissolve the smoke generated by the laser surgery. Further, as... Figure 3 As shown, in this embodiment, the water injection valve 3 is a flow regulating valve, which can adjust the flow rate of physiological saline sprayed from the spray hole 211 according to actual needs, so as to achieve the functions of cleaning wounds and dissolving smoke during surgery. Preferably, the water injection valve 3 is a double-pass Luer valve.

[0044] Furthermore, such as Figure 4 and Figure 5 As shown, the outer tube assembly 2 includes an outer tube 21 with a water inlet 212 and a sealing fitting 22 that is sleeved on the outer tube 21 and sealed to the outer tube 21 to form a connecting cavity. The water outlet pipe 32 of the water inlet valve 3 is directly connected to the sealing fitting 22 so that the water outlet pipe 32 communicates with the water inlet 212 through the connecting cavity. In this embodiment, the sealing fitting 22 is generally cylindrical with a hollow structure in the middle, including a front sealing fitting 221 and a rear sealing fitting. The rear sealing fitting includes an upper sealing fitting 222 and a lower sealing fitting 223, where "front" refers to the end pointing towards the patient and "rear" refers to the end away from the patient.

[0045] Specifically, the front sealing pipe 221 wraps around and fixes the surface of the outer pipe 21. A first sealing plug 9 is sandwiched between the sealing pipe 22 and the outer pipe 21. Under the action of the positioning member 8, the three parts of the sealing pipe 22, the outer pipe 21 and the first sealing plug 9 are pressed and fixed to prevent water leakage at the joint. The rear sealing pipe is divided into two parts, including an upper sealing pipe 222 and a lower sealing pipe 223. The upper sealing pipe 222 is sleeved with the water outlet pipe 32 and sealed and fixed. A third sealing plug 11 is provided between the upper sealing pipe 222 and the water outlet pipe 32. The third sealing plug 11 has a progressive stepped tubular structure. The water outlet pipe 32 passes through the third sealing plug 11 and is inserted into the upper sealing pipe 222. The third sealing plug 11 forms a sealing structure between the upper sealing pipe 222 and the water outlet pipe 32. The lower sealing tube 223 is sleeved on the outer tube 21 for introducing the laser fiber. A second sealing plug 10 is provided between the inner tube 1 and the outer tube 21. The second sealing plug 10 is in the shape of a stepped tube. Part of the second sealing plug 10 is embedded in the gap formed between the inner tube 1 and the outer tube 21 to seal the water flow there. The other part is covered by the lower sealing tube 223.

[0046] Specifically, the first sealing plug 9 and the second sealing plug 10 are used to seal the front and rear sides of the front sealing tube 221 and the lower sealing tube 223 connected to the outer tube 21, respectively. The outer diameter of the first sealing plug 9 is generally larger than the outer diameter of the second sealing plug 10. The front end of the first sealing plug 9 abuts against the positioning member 8. The inner surface of the tubular body of the first sealing plug 9 is in close contact with the outer surface of the outer tube 21, wrapping the outer tube 21. The outer surface of the tubular body of the first sealing plug 9 is wrapped by the front sealing tube 221. The rear end of the intermediate step of the second sealing plug 10 abuts against the rear end of the lower sealing tube 223. The inner surface of the tubular body of the second sealing plug 10 is tightly attached to the outer surface of the inner tube 1, and the outer surface of the tubular body of the second sealing plug 10 is tightly attached to the inner surface of the outer tube 21. The second sealing plug 10 blocks the water flow at the gap between the outer tube 21 and the inner tube 1, and the rear end of the intermediate step of the second sealing plug 10 blocks the rear ends of both the outer tube 21 and the inner tube 1, separating the inlet channel of the optical fiber 6 from the water injection channel to prevent water from entering. Through the cooperation of the sealing tube 22, the first sealing plug 9, the second sealing plug 10, and the third sealing plug 11 with the inner tube 1 and the outer tube 21, the rear end of the water injection chamber and the water injection port 212 are sealed to prevent leakage. This further enables the spraying of saline solution to clean wounds and dissolve fumes. In this embodiment, the outer tube 21 is made of metal tubing or polymer material.

[0047] To prevent the sealing tube 22 from rotating relative to the outer tube 21, this embodiment uses positioning elements 8 to position the sealing tube 22 and the outer tube 21. The positioning elements 8 are fixedly connected to the outer tube 21 in pairs and symmetrically. The positioning elements 8 are provided with protrusions, and the sealing tube 22 is provided with an open L-shaped groove 2211. The protrusions of the positioning elements 8 are inserted into the L-shaped groove 2211 and rotated in a certain direction to achieve positioning between the sealing tube 22 and the outer tube 21.

[0048] Furthermore, such as Figures 1 to 6 As shown, the fiber optic implant for laser surgery also includes a housing 4. The end of the outer tube 21 without the water spray hole 211 is placed inside the housing 4, while the end of the outer tube 21 with the water spray hole 211 extends out of the housing 4. The housing 4 protects the outer tube assembly 2, improves the overall appearance of the fiber optic implant for laser surgery, and facilitates gripping. The housing 4 includes a front handle housing 41 and a rear handle housing 42, which are detachably connected for easy assembly and disassembly. The front handle housing 41 has an anti-slip coating to improve grip friction and comfort, reducing hand and finger fatigue during prolonged use. The rear handle housing 42 includes two opposing and connected half-housings for installing a water injection valve 3. The aforementioned manual switch 31 is exposed outside the housing 4.

[0049] Furthermore, such as Figures 1 to 6 As shown, the inner tube 1 is used to pass through the optical fiber 6. One end of the housing 4 is connected to a locking part, which includes at least two circumferentially arranged claws 43 that form a through hole. The claws 43 are capable of elastic deformation. One end of the optical fiber 6 passes through the inner tube 1, the housing 4, and the through hole in sequence. The locking part is covered with a protective cover 5 that is threadedly connected to it, which is used to fix the optical fiber 6 relative to the locking part. Specifically, a locking part is provided at the end of the handle rear housing 42 away from the handle front housing 41. The locking part is provided with claws 43 that are capable of elastic deformation and have threads on their outer surface. A fixing plug 7 is installed inside the claws 43. The fixing plug 7 is roughly a hollow conical structure with a top the size of a nail head and a hollow middle. The diameter of the fixing plug 7 is smaller at the end closer to the handle rear housing 42 and larger at the end farther away from the handle rear housing 42. The small-diameter end of the fixing plug 7 is inserted into the insertion hole, and the optical fiber 6 passes through the fixing plug 7. It is threadedly connected to the locking part via the protective cover 5, causing the inner wall of the protective cover 5 to apply force to the claw 43. The claw 43 elastically deforms and squeezes the fixing plug 7, thereby fixing and encasing the optical fiber 6 within the fixing plug 7. The fixing plug 7 not only secures the optical fiber 6, preventing it from moving back and forth, but also provides a seal and prevents the claw 43 from directly damaging the optical fiber 6. The protective cover 5 secures the optical fiber 6, and after unscrewing the cover 5, the optical fiber 6 can be moved and adjusted. To facilitate unscrewing the cover 5, an anti-slip structure is provided on its outer surface to increase friction.
