Description

Technical Field

[0001] This utility model relates to the field of surgical auxiliary device technology, specifically a visual field obstruction device for patients undergoing perineal and lower limb local anesthesia surgery. Background Technology

[0002] During perineal and lower limb local anesthesia surgery, the patient is fully conscious and in a state of tension throughout the procedure. In particular, the visual impact of being able to see the surgical area can cause psychological trauma, especially in pediatric circumcision. Children are often significantly tense, lying flat, and may lift their heads during the procedure due to tension, which can increase their fear and make them unable to cooperate.

[0003] At present, no relevant visual field blocking devices for outpatient local anesthesia surgery below the umbilicus have been found. Therefore, a visual field blocking device for patients undergoing perineal and lower extremity local anesthesia surgery is proposed to solve the above problems. Utility Model Content

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a visual field blocking device for patients undergoing perineal and lower limb local anesthesia surgery. It has the advantages of blocking the patient's direct line of sight to the surgical area from below the navel, reducing visual impact, and being flexible and versatile in adjustment as well as stable and reliable in fixation. It solves the problem that patients (especially children) experience tension and fear due to seeing the surgical procedure while awake during perineal and lower limb local anesthesia surgery, leading to decreased cooperation.

[0005] (II) Technical Solution The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A visual field obstruction device for patients undergoing perineal and lower limb local anesthesia surgery includes a mounting frame. A mounting base is provided on the right side of the mounting frame. A limiting circular hole distributed in a ring array is opened on the right side of the mounting base. A first joint sleeve is rotatably connected to the mounting base. A limiting bolt adapted to the first joint sleeve is threadedly connected to the right side of the mounting base. A locking component extending to the left side of the first joint sleeve and adapted to the limiting circular hole is provided on the right side of the first joint sleeve. A vertical rod is fixedly connected to the top of the first joint sleeve. A limiting groove distributed in a ring array is opened on the outer side of the upper end of the vertical rod. A second joint sleeve rotatably connected to the upper end of the vertical rod and located outside the limiting groove is mounted on the outer side of the vertical rod. A limiting bolt adapted to the second joint sleeve is threadedly connected to the top of the vertical rod. A positioning component distributed in a ring array and extending to the inner side of the second joint sleeve and adapted to the limiting groove is provided inside the second joint sleeve. A horizontal bar is fixedly connected to the left side of the second joint sleeve. A surgical covering cloth is hung on the outer side of the horizontal bar.

[0006] The beneficial effects of this utility model are: This device for blocking the patient's field of vision during perineal and lower limb local anesthesia surgery is secured to one side of the bottom of a simple operating table via a mounting frame. Pulling the locking assembly rotates the upright rod until it is horizontal or vertical. Releasing the locking assembly locks the upright rod in place. When the upright rod is perpendicular to the operating table, rotating the horizontal bar horizontally causes the positioning component to engage with the limiting hole, providing a slight jolt. This aligns the horizontal bar with the mounting frame and above the patient's chest and abdomen. At this point, external force is required to rotate the horizontal bar, causing the surgical shading cloth to fall and form a visual barrier, blocking the patient's field of vision. This addresses the tension and fear caused by visual exposure during surgery. It offers advantages such as blocking the patient's direct line of sight from below the navel to the surgical area, reducing visual impact, flexible adjustment, and reliable fixation.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the locking assembly includes a dial ring, a connecting rod, a retaining ring, a conical rod, and a first spring. The right side of the first joint sleeve is provided with a dial ring adapted to the limiting bolt. The left side of the dial ring is fixedly connected with a connecting rod that is symmetrically distributed vertically and extends into the interior of the first joint sleeve. The left end of the connecting rod is fixedly connected with the same retaining ring located inside the first joint sleeve. The left side of the retaining ring is fixedly connected with a conical rod that is distributed in a circular array, extends to the left side of the first joint sleeve, and is adapted to the limiting circular hole. The interior of the first joint sleeve is provided with a first spring that abuts against the right wall of its inner cavity and the left side of the retaining ring.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by pulling the retaining ring through the dial ring and connecting rod, the conical rod is pulled to separate it from the limiting round hole, and at the same time the first spring is compressed, thereby releasing the limitation on the first joint sleeve. The upright can then be rotated. When the upright is rotated to a horizontal or vertical position, the dial ring is released, and the first spring pushes the retaining ring to insert the conical rod into the limiting round hole, which can lock and limit the first joint sleeve.

[0010] Furthermore, the positioning component includes a ball joint rod and a second spring. The interior of the second joint sleeve is provided with ball joint rods arranged in a circular array and extending to its inner side and adapted to the limiting groove. The opposite side of each ball joint rod is provided with a second spring located inside the second joint sleeve.

[0011] The beneficial effect of adopting the above-mentioned further solution is that when the upright is perpendicular to the operating table, the horizontal bar is rotated horizontally. When the horizontal bar is perpendicular or parallel to the mounting frame, the ball joint automatically enters the limiting hole under the action of the second spring, which will provide a sense of jerk. This makes the horizontal bar parallel to the mounting frame and above the patient's chest and abdomen. At this time, the horizontal bar needs to be pushed by external force to rotate. The horizontal bar will not rotate freely, and the surgical drape will fall down to form a visual barrier.

[0012] Furthermore, a handwheel screw extending into the left side of the mounting frame is threadedly connected, and a top plate is rotatably connected to the right end of the handwheel screw; Furthermore, rubber pads are affixed to the right side of the top plate and the right wall of the inner frame of the mounting frame.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by fitting the mounting frame under the bottom of the simple operating table and tightening the handwheel screw, the operating table is clamped between the top plate and the right wall of the inner frame of the mounting frame, and the rubber pad provides sufficient friction.

The left end of the connecting rod 502 is fixedly connected to the same retaining ring 503 located inside the first joint sleeve 4. The left side of the retaining ring 503 is fixedly connected to a conical rod 504 that is distributed in a ring array and extends into the left side of the first joint sleeve 4 and is adapted to the limiting circular hole 3. The interior of the first joint sleeve 4 is provided with a first spring 505 that abuts against the right wall of its inner cavity and the left side of the retaining ring 503. The positioning component 9 includes a ball joint rod 901 and a second spring 902. The interior of the second joint sleeve 8 is provided with ball joint rods 901 arranged in a ring array and extending to its inner side and adapted to the limiting groove 7. The opposite side of the ball joint rod 901 is provided with a second spring 902 located inside the second joint sleeve 8. The left side of the mounting frame 1 is threaded with a handwheel screw 12 extending into it, and the right end of the handwheel screw 12 is rotatably connected to a top plate 13; Rubber pads 14 are affixed to the right side of the top plate 13 and the right wall of the inner frame of the mounting frame 1.

[0018] Working principle: Step 1: Place the mounting frame 1 on the bottom of the simple operating table, tighten the handwheel screw 12, clamp the operating table between the top plate 13 and the right wall of the inner frame of the mounting frame 1, and the rubber pad 14 provides sufficient friction to secure the device to one side of the bottom of the simple operating table.
