Abstract
Description
Technical Field
[0001] This utility model relates to the field of interventional surgical auxiliary devices, and in particular to a support device for interventional surgery. Background Technology
[0002] In interventional surgery, especially neurosurgical procedures under general anesthesia, the safety of the surgical procedure and the maintenance of the patient's physiological state are of paramount importance. Currently, to create a sterile environment during surgery, a large area of sterile drape is typically laid over the patient's body. However, this traditional method of draping has significant drawbacks.
[0003] In interventional procedures such as neurological general anesthesia, patients are unconscious, with suppressed spontaneous breathing or complete reliance on mechanical ventilation. When a sterile drape covers the patient's face, it can severely impair their breathing. The drape may directly compress the patient's mouth and nose, causing partial airway obstruction and increasing respiratory resistance. Even slight compression can lead to poor ventilation and hypoxia during prolonged surgery, reducing patient tolerance and hindering monitoring of their condition by medical staff.
[0004] Therefore, there is a need for a support device for interventional procedures that can effectively support sterile drapes. Utility Model Content
[0005] The purpose of this invention is to provide a support device for interventional surgery that can solve the above-mentioned technical problems, effectively support sterile drapes, and not affect the patient's breathing.
[0006] This utility model provides a support device for interventional surgery, including an adjustable connecting frame that is detachably connected to the head of the interventional operating table. The connecting frame is vertically arranged, and a horizontally arranged telescopic support part is connected to the top of the connecting frame.

[0027] Example 1
[0028] like Figure 1-3As shown, a support device for interventional surgery includes an adjustable connecting frame detachably connected to the head of an interventional operating table. The connecting frame is vertically arranged and includes an adjusting component 5, an inner tube 3, and an outer tube 1 that are nested together. The bottom end of the outer tube 1 is closed and connected to the head of the interventional operating table by a bolt 2. The inner tube 3 can move vertically within the outer tube 1 under the action of the adjusting component 5, and the top of the inner tube 3 is connected to a support part 4. The adjusting component 5 includes an adjusting rod 503. One end of the adjusting rod 503 away from the inner tube 3 has a knob 504, and the other end passes inward through the outer tube 1 and connects to a first conical tooth 502. The inner tube 3 has a threaded section 301, which is rotatably connected to a second conical tooth 505. The second conical tooth 505 meshes with the first conical tooth 502. The outer tube 1 has a cavity 501 inside, and both the first conical tooth 502 and the second conical tooth 505 are located within the cavity 501. The staff rotates the knob 504 to drive the first conical tooth 502 and the second conical tooth 505 to rotate, thereby causing the inner tube 3 to move vertically along the axis of the outer tube 1 and adjusting the height of the top support part 4.
[0029] A limiting block 302 is provided on the upper part of the inner tube 3 of the adjusting rod 503, and a limiting groove 101 is provided on the inner side of the outer tube 1 along the axial direction. The limiting block 302 can slide along the limiting groove 101. The limiting block 302 and the limiting groove 101 cooperate with each other to restrict the rotational freedom of the inner tube 3, so that it can only move in the vertical direction. This not only ensures the stability of the connecting frame when adjusting the height and prevents the inner tube 3 from shaking or shifting in the outer tube 1, but also ensures the normal operation of the adjusting component 5 and avoids failure of the conical tooth engagement or damage to the thread due to the rotation of the inner tube 3. Preferably, the length of the limiting groove 101 is less than or equal to the length of the thread section 301, which can effectively limit the travel of the limiting block 302 and prevent the second conical tooth 505 from dislodging from the thread section 301 during the adjustment process.
[0030] The top of the inner tube 3 is connected to a horizontally arranged retractable support 4. The support 4 includes two parallel support arms 401. The top of the inner tube 3 is connected to the center of one of the support arms 401 to prevent the center of gravity of the support 4 from shifting. The support arms 401 are connected by a scissor mechanism. The length of each support arm 401 is 30-50cm to ensure coverage of the patient's face. The scissor mechanism includes a scissor frame 402. Two grooves 404 are provided along the axial direction of each support arm 401 on one side closest to each other. Each groove 404 corresponds to a slider 403, which engages with the groove 404 and can slide along the groove 404. The slider 403 is hinged to the ends of the two scissor bars of the scissor frame 402. By limiting the length of the groove 404, the extension range of the scissor frame 402 can be limited, preventing excessive stretching and ensuring stability. The two opposite ends of the support arms 401 are connected by a telescopic rod, further strengthening the support 4. The surface of the scissor lift 402 is sandblasted to achieve a roughness of Ra3.2-Ra6.3. When the scissor lift 402 is under pressure, the friction can effectively prevent it from shrinking.
[0031] The support arm 401 connected to the connecting frame is equipped with several fixing clips 6, and the clamping parts of the fixing clips 6 are all covered with silicone sleeves. The fixing clips 6 provide reliable fixing points for sterile drapes; the silicone sleeves on the clamping parts of the fixing clips 6 not only increase the friction between the clamping parts and the sterile drapes, allowing the sterile drapes to be firmly fixed to the support arm 401, preventing the sterile drapes from slipping off due to changes in patient position or other factors during surgery, but also avoid possible scratches or damage when the clamping parts directly contact the sterile drapes.
[0032] The connecting frame and support part 4 are made of carbon fiber or polyetheretherketone. These materials have good mechanical properties and chemical corrosion resistance, and will not affect the normal operation of various medical devices (such as DSA equipment, monitors, etc.) during interventional surgery, nor will they interfere with electromagnetic signals.
[0033] Working principle:
[0034] Connect the bottom of the connecting frame to the bottom bolt 2 of the interventional operating table. After installation, the connecting frame is set vertically, and the support part 4 is located in the area above the patient's head. The staff rotates the knob 504 to drive the first conical tooth 502 and the second conical tooth 505 to rotate, thereby causing the inner tube 3 to move slowly along the axis of the outer tube 1, and adjusting the height of the top support part 4 to the target position.
[0035] Pull the outer support arm 401, which in turn stretches the scissor lift 402. The slider 403 slides along the groove 404, stretching the support arm 401 to cover the patient's face. Then, lay out a sterile drape, unfolding it and starting from above the patient's head to cover the corresponding parts of the patient's body. Place the edges of the sterile drape on the two support arms 401 of the support part 4 in sequence, and use the fixing clips 6 on the support arms 401 to clamp the sterile drape.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
