Description

Technical Field

[0001] The invention relates to the technical field of surgical instruments, and in particular to a minimally invasive treatment device for patients with tophi on the surface of limbs. Background Art

[0002] Gout is a metabolic arthritis caused by the deposition of urate crystals, which mainly affects the joints of the limbs. In severe cases, tophi may form, leading to joint deformation and dysfunction.

[0003] At present, the treatment methods of tophi include drug therapy, arthroscopic technology and water injection therapy technology. Drug therapy is the basic treatment for gout patients. Drug therapy has limited effect on existing tophi and requires long-term medication, and patient compliance is poor. Arthroscopic technology is a minimally invasive surgical method widely used in the field of orthopedics. However, arthroscopic surgery requires special equipment and a high technical threshold. The trauma of arthroscopic surgery is relatively large, and the patient's recovery time is long after surgery. It is mainly suitable for lesions in deep joints. The treatment efficiency of tophi on the surface of the limbs is low, and it is not suitable for promotion in grassroots hospitals. The incidence of postoperative complications is high, especially wound infection and joint stiffness. Water injection therapy is a non-invasive physical therapy method that uses high-pressure water flow to impact tophi to achieve the effect of decomposition and excretion. However, this method has the problems of low efficiency and long treatment cycle. In addition, water injection therapy requires special equipment support. Therefore, it is of great clinical significance to develop an efficient and minimally invasive tophi treatment device suitable for grassroots hospitals. Summary of the invention

[0004] The purpose of the present invention is to provide a minimally invasive treatment device for patients with tophi on the surface of limbs to solve the problems raised in the above-mentioned background technology.

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.

[0032] Please refer to the attached Figures 1-10 , this application provides the following technical solutions.

[0033] Embodiment 1: A minimally invasive treatment device for patients with gouty tophi on the surface of the limbs, comprising an operating rod 1, an operating handle 2 is movably sealed and sleeved on one side of the operating rod 1, an operating head 3 is provided on one side of the operating rod 1, an open spoon groove 4 is provided on one side of the operating head 3, a hollow channel 5 is provided on one side of the operating rod 1 through the center, the operating head 3 is connected to one side of the operating rod 1, a switching component is provided on the side of the operating rod 1 away from the operating head 3, the switching component includes a medical tee 24, the length of the operating rod 1 is 22 cm, the opening width of the open spoon groove 4 is 3 mm, and the hollow channel 5 is provided. The diameter is 1.5mm, one end of the medical tee 24 is connected and plugged with a transfer hose 23, and the end of the operating rod 1 away from the operating head 3 is provided with a group screw head 22, and the transfer hose 23 is connected to the group screw head 22 through a docking nut, and the transfer hose 23 is connected to the hollow channel 5. When in use, the operating rod 1 is connected to the medical tee 24 through the transfer hose 23. The two interfaces of the medical tee 24 away from the transfer hose 23 can be connected to the drug injection line, flushing line, or suction line according to needs, wherein the injection line can be injected with anti-inflammatory drugs and local anesthetic drugs, etc.;

[0034] The length of the operating head 3 from the operating handle 2 is less than the length of the operating handle 2 itself. The surface of the operating handle 2 is provided with anti-slip grooves. The operating rod 1 is located on the assembly screw head 22 and is provided with an end reference block 6 on the side close to the operating handle 2. An indicator block 7 is provided on one side of the end reference block 6, and the indicator block 7 is arranged corresponding to the opening direction of the open spoon groove 4. The anti-slip grooves of the operating handle 2 are convenient for the operator to perform hand-held operation, and the indicator block 7 can facilitate the operator to timely understand the opening position of the open spoon groove 4.

[0035] When the operating rod 1 is in normal use, the transfer hose 23 applies a pressure of 0.5 - 1.5 MPa to the sterile normal saline fed into the opening spoon groove 4, and the water flow rate is 50 ml / s. When the operating rod 1 is connected to the flushing pipeline, by injecting sterile normal saline, it can ensure sufficient scouring force on the surface of the tophus without damaging the surrounding tissues.

[0036] Before the operation, a comprehensive physical examination of the patient is carried out first, including blood uric acid level, renal function, liver function, electrocardiogram, etc., to ensure that the patient is suitable for minimally invasive treatment. Use ultrasound examination to determine the specific location of the tophus, and mark the incision position under ultrasound guidance.

[0037] Then, under local anesthesia (such as using 2% lidocaine for local anesthesia), with an incision length of 5 mm, the skin is incised and the device is inserted. The ultrasound guidance technology can be combined to accurately locate the tophus. The surface of the tophus is flushed through the water spraying function of the opening spoon groove 4 to weaken the adhesion between the tophus and the surrounding tissues. Anti-inflammatory drugs (such as dexamethasone) are injected through the opening spoon groove 4 to achieve precise drug delivery. The tophus is aspirated into fragments through the negative pressure suction device and the opening spoon groove 4 to further improve the treatment effect.

[0038] Combined with the specific condition of the patient, antibiotics can be used after the operation to prevent infection and avoid postoperative complications. After the operation, traditional Chinese medicine external application (such as Coptis chinensis ointment), hormone treatment (such as prednisone dragon), and physical therapy (such as infrared irradiation) are adopted to promote wound healing and anti-inflammatory, and reduce the recurrence rate of gout.

[0039] Embodiment 2: On the basis of Embodiment 1, a maintenance and treatment component is provided to quickly handle the blockage of tophus fragments in the hollow channel 5. The maintenance and treatment component is arranged in the operating handle 2. The maintenance and treatment component includes a top push rod 15. The two ends of the operating handle 2 sleeving the operating rod 1 are respectively plugged with a first sealing ring 8 and a second sealing ring 9. The inner circumferential sides of the first sealing ring 8 and the second sealing ring 9 elastically sleeve the outer surface of the operating rod 1. The operating handle 2 can rotate and slide along the operating rod 1 above the operating rod 1. At the same time, the operating handle 2 is hermetically sleeved on the operating rod 1 through the first sealing ring 8 and the second sealing ring 9, so as to achieve a good sealing state between the operating handle 2 and the operating rod 1.

[0040] On one side of the operating rod 1, a strip window 10 is provided through the hollow channel 5. On the side of the operating handle 2 close to the strip window 10, a shielding and sealing piece 11 is inserted. The cross-sectional width of the shielding and sealing piece 11 is greater than that of the strip window 10, and one side of the shielding and sealing piece 11 is closely attached to the operating rod 1. On the side of the operating handle 2 far from the shielding and sealing piece 11, a storage groove 12 is provided. On the outer side of the operating handle 2 and close to the position of the storage groove 12, a spring groove 13 is provided. A guide groove is provided through the spring groove 13 and communicates with the storage groove 12. A synchronous guide block 14 is movably inserted through the guide groove. Inside the storage groove 12 and the spring groove 13, a top push rod 15 and a pressing block 16 are respectively provided on the synchronous guide block 14. The length of the pressing block 16 is equal to the length of the operating head 3 from the operating handle 2, and the width of the pressing block 16 is equal to the width of the strip window 10. On one side of the pressing block 16 located in the spring groove 13, a number of reset springs 17 are symmetrically provided. The position where the hollow channel 5 passes through the operating rod 1 is inside the operating handle 2 during normal use. Under the multiple sealing states of the shielding and sealing piece 11, the first sealing ring 8 and the second sealing ring 9, it is ensured that when the solution or gas passes through the hollow channel 5, it does not affect normal use;

[0041] When the operating handle 2 rotates along the operating rod 1 to misalign the shielding and sealing piece 11 with the strip window 10 and the top push rod 15 is docked with the strip window 10, pressing the pressing block 16 can control the synchronous guide block 14 and the top push rod 15 to penetrate and insert into the strip window 10. At this time, the top push rod 15 is inside the hollow channel 5. By sliding the operating handle 2 along the operating rod 1, the synchronous guide block 14 can slide in the strip window 10, and the top push rod 15 can move in the hollow channel 5. Furthermore, the end of the top push rod 15 can be close to the opening spoon groove 4 to push the ventilation stone fragments that may occur at the connection position of the opening spoon groove 4 and the hollow channel 5 out of the hollow channel 5 to prevent it from blocking the hollow channel 5. After use, the top push rod 15 retracts into the storage groove 12, and the shielding and sealing piece 11 reseals the strip window 10. The reset springs 17 enable the synchronous guide block 14 and the pressing block 16 to maintain the posture of pulling the top push rod 15 into the storage groove 12. The operating rod 1 is made of medical stainless steel or titanium alloy with good biocompatibility, and the top push rod 15 is made of a high-strength medical alloy material that is resistant to bending.

[0042] On one side of the operating handle 2 close to the end reference block 6, an annular combination groove 18 is provided. On both sides of the annular combination groove 18, two positioning card slots 19 are symmetrically provided. On the side of the end reference block 6 close to the operating handle 2, two elastic buckle plates 20 are provided inside the inserted annular combination groove 18. On one side of each of the two elastic buckle plates 20, a positioning block 21 is provided. The two positioning blocks 21 are respectively inserted into the two positioning card slots 19. And the four sides of the positioning card slot 19 where the positioning block 21 is inserted into the four sides of the positioning card slot 19 are all inclined surfaces. Since the end reference block 6 and the operating rod 1 are fixedly arranged, when the operating handle 2 rotates along the operating rod 1, the end reference block 6 remains stationary. At this time, the top push rod 15 is docked or misaligned with the strip window 10. The two positioning blocks 21 are respectively alternately inserted into the two positioning card slots 19 to position and hold the operating handle 2.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
