Description

Technical Field

[0001] This utility model relates to the field of surgical protective devices, specifically to a minimally invasive surgical protective device for urology. Background Technology

[0002] With the continuous development of science and technology, the principles and technologies of lasers and X-rays are constantly being improved and developed, and are gradually being applied to the fields of medical treatment and biological research. Both lasers and X-rays have many advantages, such as efficient vaporization of lesions or fragmentation of stones in cavities through minimally invasive procedures using endoscopy, good directionality, excellent hemostasis, short operation time, minimal damage to surrounding tissues, and few surgical side effects. Moreover, surgery using lasers and X-rays does not induce the obturator nerve reflex, resulting in a high surgical safety factor, making them particularly suitable for endoscopic surgeries in urology.

[0003] Existing urological minimally invasive surgical protective devices use a lead-lined shield to cover the surgical site, protecting it from laser and X-ray radiation. An operating cavity is created within the shield to allow surgical instruments to pass through during minimally invasive surgery. However, during the procedure, if bleeding occurs unexpectedly, the shield obscures the wound, making observation difficult. Furthermore, the limited operating space inconveniences medical staff, hindering timely intervention and resulting in poor effectiveness. Therefore, a new urological minimally invasive surgical protective device is urgently needed to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a high-performance protective device for minimally invasive urological surgery that not only has good protective effect, but also increases the operating space for medical staff in response to emergencies, making it easier for medical staff to handle the situation.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a protective device for minimally invasive urological surgery, including an inverted U-shaped protective cover. An adjustment cavity is provided at the upper end of the protective cover, and an adjustment plate is installed inside the adjustment cavity. Two sets of telescopic folding covers are symmetrically installed on both sides of the adjustment plate. An L-shaped lever is provided at one end of each telescopic folding cover. Two sets of return springs are symmetrically installed on one side wall of the lever, and two sets of L-shaped limiting rods are symmetrically installed on the other side wall of the lever. A U-shaped limiting seat is fixed at the upper end of the adjustment plate at a position corresponding to the limiting rods. Multiple sets of positioning holes are arrayed on one side of the upper end of the protective cover. A bracket is fixed at the upper end of the adjustment plate. Two sets of telescopic columns are symmetrically installed at one end of the bracket. A positioning spring is sleeved on the outer side of each telescopic column. A T-shaped positioning frame is fixed to the movable part of each telescopic column. A universal ball is installed in the middle of the adjustment plate, and a through cavity is provided on the universal ball.

[0008] Furthermore, the adjusting plate is slidably connected to the adjusting cavity, one end of the telescopic folding cover is fixedly connected to the adjusting cavity and the other end is fixedly connected to the lever plate, and the lever plate is slidably connected to the adjusting cavity.

[0009] By adopting the above technical solution, the adjustment plate can slide within the adjustment cavity according to the location of the patient's surgery, thereby adjusting its position, and the telescopic folding cover always seals the adjustment cavity.

[0010] Furthermore, one end of the reset spring is welded to the dial plate, and the other end of the reset spring is welded to the protective cover.

[0011] By adopting the above technical solution, when an unexpected situation occurs, after the fixing of the dial plate is released, the return spring can drive the dial plate and the telescopic folding cover to retract and reset under the action of the rebound force, thereby increasing the operating space of medical staff and enabling them to deal with the situation in a timely manner.

[0012] Furthermore, the limiting rod is rotatably connected to the lever plate, the limiting rod is connected to the limiting seat through a slot, and the limiting seat is mounted on the adjusting plate by screws.

[0013] By adopting the above technical solution, the combination of the limiting rod and the limiting seat facilitates both the connection of the lever and the adjustment plate and the disconnection.

[0014] Furthermore, the positioning hole is formed on the protective cover, the bracket is welded to the adjustment plate, the telescopic column is fixed between the bracket and the positioning frame, and the positioning spring is welded to the outer wall of the telescopic column.

[0015] By adopting the above technical solution, the telescopic column combined with the positioning spring can drive the positioning frame to move, thereby fixing the adjustment plate and releasing the fixing.

[0016] Furthermore, the positioning frame is inserted into the positioning hole, and the positioning hole matches the specifications of the positioning frame.

[0017] By adopting the above technical solution, when the positioning frame is in the positioning hole, the adjusting plate with the adjusted position can be fixed, and when the two are separated, the fixation can be released.

[0018] Furthermore, the omnidirectional ball is rotatably mounted on the adjustment plate, and the cavity is formed on the omnidirectional ball.

[0019] By adopting the above technical solution, the cavity provides a through space for surgical instruments, and the omnidirectional ball facilitates the operation of surgical instruments by medical staff.

[0020] Furthermore, two sets of U-shaped clamping plates are symmetrically fixed on both sides of the bottom of the protective cover, and two sets of locking screws are symmetrically installed on the clamping plates. A locking plate is rotatably installed on one end of each locking screw.

[0021] By adopting the above technical solution, rotating the locking screw can fix the device on the operating table through the locking plate.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model has the following advantages:

[0024] To address the shortcomings of existing urological minimally invasive surgery protective devices, which rely on lead-lined shields to protect the surgical site from laser and X-ray radiation and have an operating cavity through which surgical instruments pass, this invention addresses the issue of ineffectiveness in cases of bleeding. The shields obstruct observation of the wound, and the limited operating space hinders timely intervention by medical staff. This invention incorporates a return spring, a lever, a limiting seat, and a limiting rod. During surgery, the telescopic folding cover maintains a sealed adjustment cavity, protecting medical staff. In case of an emergency, rotating the limiting rod releases the lever from the limiting seat, and the return spring's rebound force causes the lever and telescopic folding cover to retract and return to their original position, increasing the operating space for medical staff and enabling timely intervention, thus improving the device's performance.
