Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a medical positioning device. Background Technology

[0002] Percutaneous nephrolithotomy (PCNL) is a modern minimally invasive technique for treating kidney stones. Commonly known as "hole-in-the-hole stone removal," it involves making a small incision (approximately 0.5 cm) in the patient's lower back to create a access channel. A nephroscope is then inserted, and the kidney stones, especially staghorn calculi and upper ureteral stones, are broken up using an ultrasonic pneumatic lithotripter or holmium laser lithotripter before being removed. PCNL is an important part of urological surgery, and in the treatment of upper kidney stones and upper ureteral stones, it, along with ureteroscopy and extracorporeal shock wave lithotripsy (ESWL), has become a major modern treatment method, completely changing the traditional open surgery approach. Through a comprehensive approach combining PCNL, ureteroscopy, ESWL, and laser lithotripsy, more than 90% of kidney stones can be treated without open surgery.

[0003] Before the actual percutaneous nephrolithotomy, after local or general anesthesia, the patient needs to be positioned on the operating table in a prone position with their lower back exposed to facilitate incision and insertion of the nephroscope. Traditional operating tables have flat leg panels, which cannot adjust the knee flexion for special positions, such as the prone position with the healthy side bent and legs apart. Therefore, we propose a medical positioning device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a medical positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical positioning device, comprising an arc-shaped support plate one and an arc-shaped support plate two arranged opposite to each other. One end of the arc-shaped support plate one is fixedly connected to one end of a hinge plate one. The other end of the hinge plate one is rotatably sleeved with a hinge shaft. One end of the hinge shaft is fixedly connected to one end of the hinge plate two. The other end of the hinge plate two is fixedly connected to the bottom of one end of the arc-shaped support plate two. A movable cap is slidably engaged at the other end of the hinge shaft. Anti-slip grooves are respectively provided on the inner walls of both sides of the movable cap. Limiting strips are slidably engaged in the anti-slip grooves. One end of the limiting strip is fixedly connected to the hinge plate one. The movable cap has recessed cylindrical grooves on both sides of one end face near the hinge plate. The inner walls of the cylindrical grooves are fixedly connected to one end of a small tension spring, and the other end of the small tension spring is fixedly connected to the hinge plate.

[0006] Preferably, multiple fixing rings are fixedly connected to both sides of the bottom wall of the first and second arc-shaped support plates, and the multiple fixing rings are arranged symmetrically in pairs.

[0007] Preferably, the opposite end faces of the first and second arc-shaped support plates are respectively provided with arc-shaped openings.

[0008] Preferably, the outer wall of the hinge shaft away from the second hinge plate has multiple slots, which are evenly distributed around the circumference of the hinge shaft.

[0009] Preferably, the inner wall of the movable cap is fixedly connected with multiple locking strips, which slide and engage with the locking grooves.

[0010] Preferably, the limiting strip has an L-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using a fixing ring in conjunction with a rope, the first or second arc-shaped support plate can be fixedly tied to the leg board of the operating table. At the same time, the straps in conjunction with the fixing ring can bind and fix the patient's legs. When a special position of knee flexion and leg separation is required, the angle of the first arc-shaped support plate can be adjusted by manually operating the movable cap to disengage it from the hinge shaft, which facilitates different angles of knee flexion adjustment of the legs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a medical positioning device, including an arc-shaped support plate 1 and an arc-shaped support plate 2 arranged opposite to each other. The device is characterized in that: one end of the arc-shaped support plate 1 is fixedly connected to one end of a hinge plate 3, the other end of the hinge plate 3 is rotatably sleeved with a hinge shaft 5, one end of the hinge shaft 5 is fixedly connected to one end of a hinge plate 4, the other end of the hinge plate 4 is fixedly connected to the bottom of one end of the arc-shaped support plate 2, and a movable cap 6 is slidably engaged at the other end of the hinge shaft 5. Anti-slip grooves 9 are respectively opened on the inner walls of both sides of the movable cap 6, and limit strips 8 are slidably engaged in the anti-slip grooves 9. One end of the limit strip 8 is fixedly connected to the hinge plate 3. The movable cap 6 has cylindrical grooves 10 recessed on both sides of one end face near the hinge plate 3. The inner walls of the cylindrical grooves 10 are fixedly connected to one end of the small tension spring 11, and the other end of the small tension spring 11 is fixedly connected to the hinge plate 3. Example

[0016] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, multiple fixing rings 7 are fixedly connected to both sides of the bottom wall of the arc-shaped support plate 1 and the arc-shaped support plate 2. The multiple fixing rings 7 are arranged symmetrically in pairs. The setting of the fixing rings 7 facilitates the limiting and fixing of the arc-shaped support plate 1 and the arc-shaped support plate 2 and the patient's leg. The inner wall of the arc-shaped concave surface of the arc-shaped support plate 1 and the arc-shaped support plate 2 is fixedly connected to a cushioning sponge pad, which improves the comfort of the contact position.

[0017] Specifically, arc-shaped openings 12 are respectively provided on the opposite end faces of arc-shaped support plate 1 and arc-shaped support plate 2. The setting of arc-shaped openings 12 allows for a larger range of adjustment when the angles of arc-shaped support plate 1 and arc-shaped support plate 2 are adjusted.

[0018] Specifically, multiple slots 51 are provided on the arc-shaped outer wall of the hinge shaft 5 away from the hinge plate 4, and the slots 51 are evenly distributed around the circumference.

[0019] Furthermore, the inner wall of the movable cap 6 is fixedly connected with multiple locking strips 61. The locking strips 61 slide and engage with the locking groove 51. When a special position of knee flexion and leg separation is required, the movable cap 6 can be manually pulled away from the hinge plate 3 by manually operating the movable cap 6. The locking strips 61 fixed to the movable cap 6 will disengage from the locking groove 51. At this time, the hinge shaft 5 can rotate, so that the angle between the arc support plate 1 and the arc support plate 2 can be adjusted, that is, the knee flexion angle of the patient's leg can be adjusted at different angles. After the adjustment is completed, the movable cap 6 is released. Under the tension of the small tension spring 11, the movable cap 6 drives the locking strips 61 to re-engage into the locking groove 51, thereby limiting and fixing the adjusted knee flexion angle.

[0020] Specifically, the limiting strip 8 has an L-shaped structure, and the anti-slip groove 9 has an annular structure. The limiting strip 8 and the anti-slip groove 9 are slidably engaged, and the limiting strip 8 prevents the movable cap 6 from falling off when it is pulled out.

[0021] The working principle and process are as follows: When a prone, leg-spread position is required, instruct the patient to lie face down on the bed. Medical staff use a rope to pass through the fixing ring 7 of either arc-shaped support plate 1 or arc-shaped support plate 2, and tie the rope to the leg board of the operating table, thus fixing arc-shaped support plate 1 or arc-shaped support plate 2 onto the leg board. Place both legs on arc-shaped support plate 1 or arc-shaped support plate 2, with the knees positioned at the hinge axis 5. The rope is then passed through the fixing ring 7 to secure the patient's legs. When a special prone, leg-spread position with the unaffected knee bent is required... By manually operating the movable cap 6, pull the movable cap 6 away from the hinge plate 3. The locking strip 61 fixed to the movable cap 6 will disengage from the locking groove 51. At this time, the hinge shaft 5 can rotate, so that the angle between the arc support plate 1 and the arc support plate 2 can be adjusted, that is, the knee flexion angle of the patient's leg can be adjusted at different angles. After the adjustment is completed, release the movable cap 6. Under the pulling force of the small tension spring 11, the movable cap 6 will drive the locking strip 61 to re-lock into the locking groove 51, thereby limiting and fixing the adjusted knee flexion angle.

[0022] 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.
