Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ophthalmic auxiliary instrument, concretely relates to a surgical instrument for assisting deep exposure of eye socket operation. BACKGROUND

[0002] Many orbital tumors, orbital fractures and orbital decompression surgery in clinic need to perform deep orbital surgery, and how to expose the surgical field well is the key to the success of the surgery. The eye surgery drag hook is a common instrument for orbital surgery, which is widely used in the resection of intraorbital tumors, orbital bone fracture repair and various intraorbital surgeries.

[0003] Through retrieval, the patent with patent publication number CN202121512509.6 discloses an eye socket surgical instrument, although the device has the advantage of convenient length adjustment when in use by pulling the drag hook rod to the left or right to adjust the total length of the drag hook rod and the handle cover, and then fixing the position of the drag hook rod by the torsional spring and the concave plate driving the arc plate to be clamped into the inside of the clamping groove, but the exposure area of the device is narrow when in use, and the soft and movable fat tissue in the deep part of the eye socket is often wrapped and obstructed by the herniated orbital fat, which hinders the vision, and there is an urgent need to seek an auxiliary instrument that can better expose the deep part of the eye socket. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides a surgical instrument for assisting deep exposure of eye socket operation, which solves the problems raised in the background art.

[0005] The utility model solves the above technical problems by the following scheme:

[0006] A surgical instrument for assisting deep exposure of eye socket operation, comprising an elongated handle, wherein one end of the elongated handle is provided with a drag hook;

[0007] A connecting plate is arranged on the drag hook, a damping sleeve is connected to the end of the connecting plate, a rotating assembly is installed in the damping sleeve, a first sector plate is connected to the rotating assembly, a through hole is formed through the drag hook, the drag hook is provided with a second sector plate which rotates around the through hole through a bearing, and the inner ring and outer ring of the bearing are respectively connected and fixed with the drag hook and the second sector plate, and the first sector plate and the second sector plate are driven to move in opposite directions to expand or move towards each other to be stored through the rotating assembly;

[0008] The rotating assembly is provided with a knob, a first connecting rod is arranged on the knob, a first tooth rod is connected to the end of the first connecting rod away from the knob, a baffle is connected to the end of the first tooth rod away from the first connecting rod through a second connecting rod, and a second tooth rod is installed on the side of the baffle facing the knob.

[0009] On the basis of the above technical scheme, the utility model further can make improvement as follows.

[0010] Further, the first and second fan-shaped plates are symmetrically distributed on the inner side and the outer side of the drag hook.

[0011] The beneficial effects of the above further scheme are:

[0012] This symmetrical distribution design not only makes the surgical instrument more visually balanced and beautiful, but more importantly, it ensures that the exposure of the surgical field is more uniform and comprehensive. When the first and second fan-shaped plates are simultaneously unfolded, they can form two symmetrical exposure areas on both sides of the drag hook, effectively increasing the width and depth of the surgical field of view. This design helps to improve the accuracy and safety of the operation, especially when dealing with complex or deep orbital surgery.

[0013] Further, the second tooth rod is provided with three, and the three second tooth rods are arranged in a ring array around the second connecting rod.

[0014] The beneficial effects of the above further scheme are:

[0015] The three second tooth rods are arranged in a ring array around the second connecting rod, which enhances the stability and controllability during the unfolding of the fan-shaped plate. Because the number of second tooth rods is increased and uniformly distributed, they can more evenly transmit force to the second fan-shaped plate, thereby avoiding unnecessary shaking or deviation during unfolding.

[0016] Further, the first and second fan-shaped plates are provided with tooth holes, and when the first tooth rod engages with the tooth hole of the first fan-shaped plate to drive the first fan-shaped plate to rotate, the second tooth rod engages with the tooth hole of the second fan-shaped plate to drive the second fan-shaped plate to unfold reversely.

[0017] The beneficial effects of the above further scheme are:

[0018] This design achieves the synchronous and reverse unfolding of the first and second fan-shaped plates. When the first tooth rod engages with the tooth hole of the first fan-shaped plate and drives it to rotate, the second tooth rod will also engage with the tooth hole of the second fan-shaped plate at the same time, and drive it to unfold reversely. This synchronous unfolding mechanism not only improves the efficiency and flexibility of the surgical instrument, but also ensures that the exposure of the surgical field is more uniform and comprehensive. In addition, since the two fan-shaped plates are unfolded reversely, they can form a larger exposure space in the surgical area, thereby facilitating more complex surgical operations by the doctor.

[0019] Further, the first connecting rod of the rotating assembly is rotatably installed in the damping sleeve.

[0020] The beneficial effects of the above further scheme are:

[0021] The first connecting rod is rotatably mounted in the damping sleeve, which provides additional stability and damping effect. The damping sleeve can slow down the speed of the first connecting rod during rotation and reduce the vibration or impact caused by rapid rotation. This stability is crucial to ensure the smoothness and controllability of the fan-shaped plate during deployment. In addition, the damping sleeve can also protect the first connecting rod from external interference and damage, thereby prolonging the service life of the surgical instrument.

[0022] The utility model provides a kind of surgical instrument for assisting deep exposure of eye socket surgery. It has the following beneficial effects:

[0023] By designing the first fan-shaped plate and the second fan-shaped plate, and symmetrically distributing them on the inner side and the outer side of the retractor, the exposure area of the surgical field can be significantly increased when they are deployed in reverse through the rotating assembly. This helps doctors see the surgical area more clearly during surgery, improving the accuracy and safety of the operation.

[0024] The deployment of the first fan-shaped plate and the second fan-shaped plate can effectively block the interference of deep orbital fat and muscle tissue to the surgical field. This helps doctors focus more on surgical operations and reduces the difficulty and risk of surgery caused by tissue obstruction.

[0025] The design of the rotating assembly allows the first fan-shaped plate and the second fan-shaped plate to be flexibly adjusted by the knob. Doctors can adjust the degree of deployment of the fan-shaped plate at any time according to the needs of the operation to adapt to different surgical scenarios and patient conditions.

[0026] The scale designed at the connection between the long handle and the retractor provides a certain positioning reference value for the doctor to locate the lesion. This helps doctors more accurately locate the lesion during surgery, improving the accuracy and efficiency of the operation.

[0027] The second tooth bar in the rotating assembly is arranged in a ring around the second connecting rod, which ensures that the fan-shaped plate is more stable during rotation and reduces the shaking or deviation caused by uneven distribution of tooth bars. BRIEF DESCRIPTION OF DRAWINGS

[0040] Example two

[0041] In order to facilitate the driving of first sector plate 5 and second sector plate 7 to unfold reversely or move towards each other by rotating assembly 4, for example, Figures 1 to 4As shown, the utility model also includes: rotary assembly 4 is equipped with knob 401, be equipped with first connecting rod 402 on knob 401, the first connecting rod 402 of rotary assembly 4 is rotationally installed in damping sleeve 3, first connecting rod 402 is rotationally installed in damping sleeve 3, this design provides additional stability and damping effect.Damping sleeve 3 can slow down the speed of first connecting rod 402 in the process of rotation, and reduce the vibration or impact generated by rapid rotation.This stability is crucial to ensure the stability and controllability of the fan-shaped plate during the unfolding process.In addition, damping sleeve 3 can also protect first connecting rod 402 from external interference and damage, thereby prolonging the service life of surgical instruments, the first connecting rod 402 away from knob 401 is connected with first rack 403, and the end away from first connecting rod 402 of first rack 403 is connected with baffle 406 through second connecting rod 404, baffle 406 is installed with second rack 405 on the side towards knob 401, second rack 405 is equipped with three, and three second rack 405 is distributed in the annular array around second connecting rod 404, three second rack 405 is distributed in the annular array around second connecting rod 404, this design enhances the stability and controllability of the fan-shaped plate during the unfolding process.Due to the increase in the number of second rack 405 and uniform distribution, they can more evenly transmit force to second fan-shaped plate 7, thereby avoiding unnecessary shaking or deviation during the unfolding process.

[0042] Working principle:

[0043] Before the operation starts, first fan-shaped plate 5 and second fan-shaped plate 7 are in the storage state, close to the inner and outer sides of drag hook 6.At this time, the knob 401 of the rotary assembly 4 is in the initial position, and the connecting rod and the rack are also in the corresponding initial state.

[0044] When the surgical area needs to be exposed, the doctor can drive the rotary assembly 4 by rotating the knob 401.When the knob 401 is rotated, the first connecting rod 402 is rotated, and then the movement of the first rack 403 is driven.The teeth on the first rack 403 are engaged with the tooth holes 501 on the first fan-shaped plate 5.As the first rack 403 rotates, it pushes the first fan-shaped plate 5 to gradually unfold along the inner side of the drag hook 6.This engagement mechanism ensures that the first fan-shaped plate 5 can be unfolded smoothly and controllably, providing a larger exposure area for the surgical field.

[0045] Similar to the first sector plate 5, the second toothed rod 405 is connected with the knob 401 through the second connecting rod 404. When the knob 401 rotates, the second connecting rod 404 also rotates, thereby driving the movement of the second toothed rod 405. The teeth on the second toothed rod 405 are engaged with the tooth holes 501 on the second sector plate 7. With the rotation of the second toothed rod 405, it pushes the second sector plate 7 to gradually unfold along the outer side of the hook 6. It should be noted that since the second sector plate 7 is connected with the hook 6 through the through hole 601 and the bearing, its unfolding will not be hindered by the hook 6.

[0046] The unfolding of the first sector plate 5 and the second sector plate 7 is coordinated. When the knob 401 is rotated, the first toothed rod 403 and the second toothed rod 405 are simultaneously driven, and push the first sector plate 5 and the second sector plate 7 to unfold, respectively. Since the two sector plates are symmetrically distributed on the inner and outer sides of the hook 6, their unfolding process can form a larger surgical field exposure area, while reducing the interference of deep orbital fat and muscle tissues with the surgical field.

[0047] The doctor can adjust the unfolding degree of the sector plate by continuing to rotate the knob 401 to adapt to different surgical needs. The greater the unfolding degree of the sector plate, the larger the exposure area of the surgical field; on the contrary, the smaller.

[0048] The scale designed at the connection between the long handle 1 and the hook 6 can provide the doctor with positioning reference value for the lesion position. The doctor can adjust the unfolding degree and position of the sector plate according to the surgical needs, in combination with the scale, to ensure the accuracy and safety of the surgery.

[0049] After the surgery, the doctor can drive the rotating assembly 4 by reversing the rotation of the knob 401 to make the first sector plate 5 and the second sector plate 7 re-stored to the initial state, facilitating the storage of the instrument.
