Description

Technical Field

[0001] This utility model belongs to the field of auxiliary suture device technology, specifically relating to an extraocular muscle clamping auxiliary suture device. Background Technology

[0002] In the field of ophthalmic surgery, extraocular muscle surgery is a common and delicate type of procedure. Extraocular muscles are muscles attached to the outer wall of the eyeball and responsible for eye movement. They play a crucial role in maintaining normal visual function and coordinating eye movements. Extraocular muscle clamping suture devices are specifically designed for extraocular muscle surgery. Their core function is to stably clamp the extraocular muscles to facilitate subsequent suturing operations by medical staff and ensure the smooth progress of the surgery.

[0003] However, current extraocular muscle suture devices on the market have some shortcomings. Due to the significant differences in patients' eye conditions, the position, length, and tension of the extraocular muscles vary. Some existing devices are difficult to adjust the distance precisely, cannot adapt to the patient's eye condition, and cannot provide a suitable clamping position and force for the extraocular muscles, increasing the difficulty and risk of surgery. Furthermore, the clamping stability during fixation suturing is poor, and the extraocular muscles are fragile and prone to slippage, leading to prolonged surgery time, secondary damage, and affecting the effectiveness of the auxiliary suture device. Therefore, the applicant proposes an extraocular muscle clamping auxiliary suture device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an extraocular muscle clamping auxiliary suture device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An extraocular muscle clamping suture device includes:

[0007] Two extraocular muscle connecting arms, each of which has a grip bar fixedly installed at one end, and each of which has a finger ring fixedly installed at the end of the grip bar away from the extraocular muscle connecting arm;

[0008] The two extraocular muscle connecting arms overlap at their center positions and are hinged together by a drive shaft to form a scissor structure. A clamping mechanism is provided on the adjacent sidewalls of the two extraocular muscle connecting arms away from the gripping rod.

[0009] One of the gripping rods has a through groove on one side, and one of the gripping rods has an installation groove at the top that communicates with the through groove. One of the gripping rods is provided with a ruler located in the through groove, and the ruler is arc-shaped. One end of the ruler is fixedly installed to the adjacent side wall of the other gripping rod.

[0010] The top of the ruler is provided with a guide groove, and multiple locking teeth are fixedly installed in a linear array on one side of the inner ring wall of the guide groove. One of the gripping rods is located in the mounting groove and is provided with a positioning mechanism.

[0011] Preferably, the top surface of the ruler is provided with a scale, and the positioning mechanism includes two mounting shells that are symmetrically fixedly installed on the inner wall of the mounting groove. The adjacent side walls of the two mounting shells are open. A telescopic rod is fixedly installed on the inner wall of one end of the two mounting shells. A limit plate is fixedly installed on the other end of the two telescopic rods. A spring is sleeved on the outside of the two telescopic rods. The two ends of the two springs are fixedly connected to one side of the limit plate and the adjacent inner wall of the mounting shell, respectively.

[0012] Preferably, a push plate is fixedly installed on the top of the limiting plate, and multiple anti-slip textures are provided on one side of the push plate. A support block is fixedly installed on the bottom of the limiting plate, and a locking tooth is fixedly installed on the bottom of the support block to engage with the locking tooth.

[0013] Preferably, the clamping mechanism includes a clamping block disposed on one side of the extraocular muscle connecting arm, and the clamping block is U-shaped. A limiting groove is formed on one side inner wall of the clamping block. A bolt is provided on the top of the clamping block. The bottom end of the bolt passes through the top of the clamping block and is rotatably connected to the bottom of the clamping block. A clamping plate is provided inside the clamping block. The outer wall of one side of the clamping block is fixedly installed with the adjacent side wall of the extraocular muscle connecting arm.

[0014] Preferably, the clamping plate has a threaded hole at the top, and the clamping plate is fitted with a bolt through the threaded hole. A limiting block adapted to the limiting groove is fixedly installed on one side of the clamping plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The positioning mechanism allows for convenient adjustment of the extraocular muscle connecting arm distance to suit the patient's eye condition. The extraocular muscle clamping auxiliary suture device is equipped with a positioning mechanism. Medical staff can push the push plate to move the limiting plate and separate the first and second clamping teeth. After the positioning is released, the gripping rod can be moved to move the extraocular muscle connecting arm and the adjacent clamping mechanism for adjustment. This allows the two clamping mechanisms to move closer to each other to suit the patient's extraocular muscle condition. During adjustment, the ruler can accurately measure the clamping distance and the gripping rod slides along the ruler, increasing the balance and stability of the adjustment. After the push plate is released, the spring pushes the limiting plate back to its original position, and the first and second clamping teeth re-clamp and fix the adjacent extraocular muscle connecting arm. This can stably control the adjustment distance, reduce surgical risks, and improve operational accuracy.

[0017] (2) The clamping mechanism effectively clamps the extraocular muscles to prevent slippage and facilitate subsequent suturing. When medical staff rotate the bolt, the clamping plate can be vertically displaced, and together with the lower end of the clamping block, it clamps the extraocular muscles to fix them, which facilitates subsequent suturing operations. The bottom of the clamping plate has anti-slip texture, which can increase friction and make the clamping more stable. At the same time, the limiting block on one side of the clamping plate is matched with the limiting groove on the inner wall of the clamping block, which can prevent the clamping plate from rotating with the bolt, ensuring the clamping effect, effectively preventing the extraocular muscles from slipping during suturing, and improving the practicality of the auxiliary suture device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1:

[0028] Please see Figures 1-5 As shown, an extraocular muscle clamping auxiliary suture device includes: two extraocular muscle connecting arms 5, one end of each of the two extraocular muscle connecting arms 5 is fixedly equipped with a gripping rod 9, and the end of each of the two gripping rods 9 away from the extraocular muscle connecting arms 5 is fixedly equipped with a finger ring 3.

[0029] The two extraocular muscle connecting arms 5 overlap at their center and are hinged together through the drive shaft 4 to form a scissor structure. A clamping mechanism 2 is provided on the adjacent side wall of the two extraocular muscle connecting arms 5 away from the gripping rod 9.

[0030] One of the gripping rods 9 has a through groove on one side, and one of the gripping rods 9 has an installation groove at the top that communicates with the through groove. One of the gripping rods 9 is provided with a ruler 6 located in the through groove. The ruler 6 is arc-shaped, and one end of the ruler 6 is fixedly installed to the adjacent side wall of the other gripping rod 9.

[0031] The top of the ruler 6 is provided with a guide groove 10, and multiple locking teeth 7 are fixedly installed in a linear array on one side of the inner ring wall of the guide groove 10. One of the gripping rods 9 is located in the mounting groove and is provided with a positioning mechanism 1.

[0032] As can be seen from the above, medical staff can adjust the two extraocular muscle connecting arms 5 by holding the ring 3 and the gripping rod 9 through the transmission shaft 4, so that they can make an arc movement with the transmission shaft 4 as the center. The medical staff can adjust and move one of the gripping rods 9 through the positioning mechanism 1, and then fix it through the first 101 in the ruler 6 and the adjacent second 7 in the guide groove 10. The scale 8 makes the operation more precise. Then, the movement of one of the gripping rods 9 can slide along the curved ruler 6, which can not only increase the balance and stability of the adjustment and movement process, but also allow the ruler 6 to more accurately measure the distance of the extraocular muscle to be clamped. Then, the extraocular muscle is clamped and fixed by the clamping mechanism 2, which can fix the extraocular muscle and facilitate the subsequent suturing operation after the extraocular muscle connecting arm 5, prevent the extraocular muscle from slipping out during the suturing process, and improve the practicality of the auxiliary suture device.

[0033] For details, please refer to Figure 3 and Figure 4 As shown, a scale 8 is provided on one side of the top surface of the ruler 6. The positioning mechanism 1 includes two mounting shells 103 that are symmetrically fixedly installed on the inner wall of the mounting groove. The adjacent side walls of the two mounting shells 103 are open. A telescopic rod 105 is fixedly installed on the inner wall of one end of the two mounting shells 103. A limit plate 104 is fixedly installed on the other end of the two telescopic rods 105. A spring 106 is sleeved on the outside of the two telescopic rods 105. The two ends of the two springs 106 are fixedly connected to one side of the limit plate 104 and the adjacent inner wall of the mounting shell 103, respectively.

[0034] A push plate 102 is fixedly installed on the top of the limiting plate 104, and multiple anti-slip textures are provided on one side of the push plate 102. A support block 107 is fixedly installed on the bottom of the limiting plate 104, and a first locking tooth 101 that engages with the second locking tooth 7 is fixedly installed on the bottom of the support block 107.

[0035] As can be seen from the above, through the setting of spring 106 and push plate 102, medical staff can push push plate 102 to move towards ring 3. Push plate 102 then drives limit plate 104 to move and through support block 107, causes locking tooth 101 to move together and separate from adjacent locking tooth 2 7, releasing the positioning of locking tooth 101. Medical staff can then move one of the gripping rods 9 to move, which can drive extraocular muscle connecting arm 5 to move and adjust clamping mechanism 2 to facilitate the two clamping mechanisms 2 to move closer to each other to perform extraocular muscle manipulation on the patient. When the clamping mechanism is close to the spring 106, the limiting plate 104 will compress the spring 106 and the limiting plate 104 as it moves. After the adjustment is made to the appropriate position, the operator releases the push plate 102, causing the spring 106 to lose its compressive force and elastically return to push the limiting plate 104 back to its original position. The limiting plate 104 then drives the push plate 102 back to its original position and, through the support block 107, drives the locking tooth 101 back to its original position, which abuts against the adjacent locking tooth 7. This achieves the goal of fixing one of the gripping rods 9, enabling more stable control of the adjustment distance, reducing surgical risks, and making the operation more precise.

[0036] Example 2:

[0037] refer to Figure 5 As shown, the clamping mechanism 2 includes a clamping block 201 disposed on one side of the extraocular muscle connecting arm 5, and the clamping block 201 is U-shaped. A limiting groove is provided on one side inner wall of the clamping block 201. A bolt 202 is provided on the top of the clamping block 201. The bottom end of the bolt 202 passes through the top of the clamping block 201 and is rotatably connected to the bottom of the clamping block 201. A clamping plate 203 is provided inside the clamping block 201. The outer wall of one side of the clamping block 201 is fixedly installed with the adjacent side wall of the extraocular muscle connecting arm 5.

[0038] As can be seen from the above, by setting the bolt 202, medical staff can rotate the bolt 202 to make the clamping plate 203 vertically displace, thereby clamping the extraocular muscle with the lower end of the clamping block 201 through the clamping plate 203, thus fixing the extraocular muscle and facilitating subsequent suturing operations. The anti-slip texture on the bottom of the clamping plate 203 can increase the friction of the clamping plate 203, making the clamping plate 203 more stable when clamping the extraocular muscle.

[0039] refer to Figure 5 As shown, the clamping plate 203 has a threaded hole at the top, and the clamping plate 203 is fitted with the bolt 202 through the threaded hole. A limiting block 204 that matches the limiting groove is fixedly installed on one side of the clamping plate 203.

[0040] As can be seen from the above, by setting the limiting groove, the limiting block 204 can limit the clamping plate 203 through the limiting groove, so as to prevent the clamping plate 203 from rotating along with the bolt 202.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
