Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a special chair for lithotomy surgery. Background Art

[0002] During surgical anorectal, urinary, and reproductive tract operations, the patient is placed in the lithotomy position after anesthesia, which is a special position of prone position, such as Figure 1 As shown in the posture diagram, the chest and head of the patient 1 on the operating table 2 are relatively low, while the hips and knees are relatively high, so that the pelvic area is raised upward. This posture allows the doctor, i.e., the operator 2, to better approach the target organ and facilitate the doctor to perform the operation. However, there are many devices related to lithotomy surgery for patients in the prior art, but there is a lack of auxiliary equipment for lithotomy operators. This posture also has certain limitations: the lithotomy surgery area is usually seriously polluted, and the operator can easily bring the pollution source to other clean areas during the operation due to the narrow operating space and the transfer of instruments. At the same time, lithotomy surgery may require the operator to maintain a specific posture for a long time, such as bending over, leaning over, etc., which puts forward requirements on the operator's physical strength and endurance. The operator's fatigue will affect the efficiency and even quality of the operation. Therefore, it is necessary to provide a special equipment for lithotomy operators to facilitate the doctor's operation, reduce intraoperative contamination and reduce surgical fatigue. The operator's sitting posture is conducive to reducing surgical fatigue and observing the surgical area, but the reasons why ordinary chairs in the prior art cannot meet the application requirements include:

[0003] First, the surgeon's operating space is limited: Since the operation needs to be performed in the patient's perineum area, the surgeon's operating space is relatively small and needs to be completed in a limited space. The surgeon's operating space is limited, which affects the accuracy and efficiency of the operation.

[0004] Second, surgical instruments are difficult to deliver quickly and accurately in a sterile manner: Since the surgeon is located between the patient's knees and the instrument nurse is located at the patient's side, the coordination between the instrument nurse and the surgeon is limited by the patient's knees. There is still a problem of poor instrument delivery and there is a risk of contact with contaminants, which affects the convenience and safety of the operation.

[0005] Third, the operator's operating comfort is insufficient: because the operator maintains a specific posture for a long time, his arms, especially the elbows, lack reliable support, the operator's physical energy consumption is still relatively large, and the seat cannot be adjusted or is inconvenient to adjust, which affects the operator's operating comfort and efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0049] In view of the technical problems in the prior art of lithotomy position surgery, the surgeon 2 has limited operating space, consumes a lot of physical strength, and the surgical instruments are difficult to be quickly and accurately delivered in a sterile manner. Figure 2~Figure 3 As shown, a preferred embodiment of the lithotomy surgery chair of the utility model is described, wherein the lithotomy surgery chair comprises a seat body 4, a slide rail system 5 and a slide rail tray 6, wherein the seat body 4 comprises a seat surface 401 and a panel 402 located in front of the seat surface 401, wherein the panel 402 is used to support the arms of the operator 2 and can make way for the legs of the operator 2, wherein the slide rail system 5 comprises at least one slide rail 51, wherein the slide rail 51 comprises an inclined section 511 and a horizontal section 512, wherein the inclined section 511 extends downward from a position close to the knee of the patient 1 to the left front of the panel 402, wherein one end of the horizontal section 512 is connected to the end of the inclined section 511, and the other end of the horizontal section 512 extends to the right front of the panel 402, and the slide rail tray 6 slides in cooperation with the slide rail 51.

[0050] like Figure 4~Figure 6 As shown, when the above-mentioned lithotomy surgery chair is used, the seat body 4 and the horizontal section 512 of the slide rail 51 are located behind the lithotomy surgery patient 1, and the inclined section 511 of the slide rail 51 is located on the side of the patient 1, and the operator 2 straddles the seat body 4: that is, the operator 2 sits on the seat surface 401 with his thighs, the operator 2 faces the panel 402, the operator 2 legs extend from the yield position of the panel 402 to the ground, the operator 2 is located between the knees of the patient 1, and the operator 2 arms are supported on the panel 402 and facing the target organ of the patient 1. Under the premise of ensuring the body position of the patient 1, the operator 2 can be placed in a fixed sitting position close to the target organ of the patient 1, which is more convenient to observe the surgical area than the standing position and has a larger operating space. In addition, since the lithotomy surgery chair can provide a fixed and comfortable position, the seat body 4 provides body support for the operator 2, and the panel 402 provides arm support for the operator 2, making it easier for the doctor to perform the surgery, reducing the inconvenience during the surgery, and reducing the doctor's physical exertion and fatigue during the surgery, which helps to improve the quality of the surgery.

[0051] The panel separates the operator from the operating area, ensuring the sterility of the operating area. At the same time, the chair body 4 can be combined with the slide rail system 5 to establish a simple operating table: since the inclined section 511 extends downward from the position close to the patient 1 knee to the left front of the panel 402, it can start from the patient 1 knee and form an inclined slope from a high place, stopping at the slope on the left side of the operator 2. Since one end of the horizontal section 512 is connected to the end of the inclined section 511, the other end of the horizontal section 512 extends to the right front of the panel 402, that is, it extends parallel to the front of the chair body 4 to the right side of the operator 2 and stops. The purpose is: Figure 6As shown, the instrument nurse can be located at the side of the patient 1, and after placing the surgical instruments in the slide tray 6, the slide tray 6 is placed on the slide rail 51. The slide tray 6 can carry the surgical instruments and slide along the inclined section 511 from the sterile area near the patient 1's knee. The slide tray 6 slides along the slide rail 51 under the action of gravity, and can slide directly to the left hand side of the operator 2, that is, below the patient 1's knee without contacting the sterile area of ​​the abdomen. The horizontal section 512 directly in front of the panel 402 provides a bracket 301 for the operator 2 to build a simple operating table. When the tray slides to the operator 2, the surgeon 2 can use the slide tray 6 as a platform to place surgical instruments, and as the number of slide trays 6 increases, the slide system 5 is divided into a sterile area, an operating area and a sterile area from left to right, the operating area is located between the surgeon 2 and the patient 1, and the sterile area is located outside the patient 1, thereby expanding the operating space, and the discarded trays can carry dirt and transfer it to the right side of the surgeon 2 and out of the operating area, ensuring the safe transfer of pollutants, realizing the rapid and accurate transfer of instruments during surgery, and avoiding the contamination of instruments during the transfer process, which is in line with the principle of sterility.

[0052] like Figure 7 As shown, further, the panel 402 is provided with two grooves 403 with top openings. For example, the upper cross-section of the panel 402 is an arc-shaped structure extending outward, so that more placement space can be reserved for the slide rail system 5 in the front of the lower part of the panel 402, which is convenient for expanding the operating range and making the groove 403 on the upper part of the panel 402 correspond to the position of the elbow of the operator 2, so as to facilitate the placement of the elbow of the operator 2 during the operation and reduce fatigue.

[0053] Furthermore, the surface of the groove 403 is covered with a soft pad, for example, the soft pad is a sponge pad, a rubber pad, etc., which is used to improve the comfort of the operator 2 when the elbow is placed in the groove 403.

[0054] Furthermore, the seat body 4 includes a lifting adjustment mechanism 7, which is used to adjust the height of the seat surface 401 and / or the panel 402. The panel 402 is provided with a control button 404 for controlling the lifting adjustment mechanism 7, for example: Figure 7~Figure 8As shown, the lifting and adjusting mechanism 7 includes a first gas rod 701 and a second gas rod 702. The first gas rod 701 is installed above the bottom foot frame 405. An adjusting rod 703 is provided between the first gas rod 701 and the seat surface 401, which belongs to the existing seat adjustment method. The adjusting rod 703 can be lifted to adjust the air pressure of the first gas rod 701 to achieve the extension and retraction of the first gas rod 701 and adjust the height of the seat surface 401, thereby facilitating the improvement of the lithotomy position surgery special chair on the basis of the existing seat; the bottom of the seat surface 401 can be connected to the support frame 407, and the second gas rod 702 is installed between the support frame 407 and the panel 402. The pneumatic switch 702 can be connected to the adjustment button through a lead wire. The adjustment button may include an up button and a down button, which are used to control the extension and retraction of the second gas rod 702 through the adjustment button to adjust the height of the panel 402. The first gas rod 701 and the second gas rod 702 can be used separately or in combination to adjust the height of the seat surface 401 and the panel 402, so that the seat body 4 can be adjusted in height, allowing the doctor to better observe the operating area and further improve the accuracy and efficiency of the operation; similarly, the first gas rod 701 and the second gas rod 702 can also be replaced by hydraulic rods, mechanical lifting structures, etc.

[0055] Furthermore, the regulating button 404 is located between the two grooves 403, so that when the surgeon 2 places his elbow in the groove 403, if the surgeon 2 needs to adjust the height during the operation, he can quickly touch the regulating button with his elbow to achieve the purpose.

[0056] Furthermore, the panel 402 is a structure that is wide at the top and narrow at the bottom, and is used to make way for the legs of the operator 2 through the narrow part at the bottom, leaving enough space for the operator 2 to move his legs, thereby improving the comfort of the operator 2.

[0057] Furthermore, a detachably connected first bracket 52 is provided between the seat body 4 and the slide rail system 5, for example: Figure 7~Figure 8As shown, the first bracket 52 includes a flange tube 521, a first connecting rod 522 and a first nut 523. One end of the flange tube 521 is connected to the panel 402. The first end of the first connecting rod 522 is embedded in the other end of the flange tube 521. The end of the first connecting rod 522 passes through the first nut 523 and is connected to the slide rail system 5 through a thread. The first nut 523 can be limited by the step at the first end of the first connecting rod 522. The first nut 523 can be threadedly connected with the flange tube 521. When installing, First, put the first nut 523 from the end of the first connecting rod 522 onto the outside of the first connecting rod 522, and connect the end of the first connecting rod 522 to the slide rail system 5 through a thread. After the flange tube 521 is connected to the panel 402, insert the head end of the first connecting rod 522 into the flange tube 521, and then tighten the flange tube 521 and the first nut 523 to achieve the connection between the flange tube 521 and the first connecting rod 522. The slide rail system 5 is connected and supported on the panel 402 through the first bracket 52 to keep the relative position of the two stable.

[0058] The relative position of the slide rail system 5 and the panel 402 can be debugged by adjusting the depth of the first connecting rod 522 connected to the slide rail system 5; when disassembling, the flange tube 521 and the first connecting rod 522 can be quickly separated by loosening the first nut 523, or the seat body 4 and the slide rail system 5 can be used separately by disassembling the first connecting rod 522 and the slide rail system 5, thereby avoiding the slide rail system 5 being supported on the seat body 4 and affecting the center of gravity of the seat body 4, and also improving the flexibility during use.

[0059] Furthermore, the chair body 4 includes a plurality of legs 405. Considering that the center of gravity may move forward when the operator 2 is operating, especially when the panel 402 provides support for the slide rail system 5, the center of gravity of the chair body 4 will move forward. The legs 405 close to the slide rail system 5 extend outward from the chair body 4. For example, the legs 405 on the same side as the slide rail 51 need to be extended to balance the overall center of gravity.

[0060] Furthermore, a detachably connected second bracket 53 is provided at the bottom of the slide rail system 5, and the second bracket 53 is used to be supported on a supporting foundation such as the ground; for example: Figure 7~Figure 8As shown, the second bracket 53 includes a support rod 531, a second connecting rod 532 and a second nut 533. A blind hole 534 is provided on the top of the support rod 531. The head end of the second connecting rod 532 is embedded in the blind hole 534, and the tail end of the second connecting rod 532 passes through the second nut 533 and is threadedly connected to the slide rail system 5. During installation, the second nut 533 is first sleeved on the outside of the second connecting rod 532 and limited by the step at the head end of the second connecting rod 532. After the tail end of the second connecting rod 532 is connected to the slide rail system 5, the head end of the second connecting rod 532 can be inserted into the blind hole 534, and the support rod 531 is connected with the second nut 533 to realize the installation of the second bracket 53, so that the bottom of the second bracket 53 can be placed on the ground, and the support height can be fine-tuned by the depth of the second connecting rod 532 screwed into the slide rail system 5.

[0061] When the first bracket 52 is removed, only the second bracket 53 can be used to support the slide rail system 5, so as to avoid affecting the center of gravity of the seat body 4 and avoiding the need to adjust the height of the second bracket 53 when fine-tuning the height of the seat body 4. When the height of the seat body 4 is relatively fixed, the first bracket 52 and the second bracket 53 can also be used in combination to achieve a better supporting effect. When disassembling, the support rod 531 and the second connecting rod 532 can be quickly disassembled by loosening the second nut 533 to achieve the disassembly of the second bracket 53. The second connecting rod 532 and the slide rail system 5 can also be disassembled by threading, and only the first bracket 52 can be used to support the slide rail system 5, so that the slide rail system 5 can be adjusted in height as a whole along with the panel 402.

[0062] Furthermore, the first bracket 52 and / or the second bracket 53 and / or the slide rail 51 are retractable structures; for example: Figure 6 As shown, a built-in telescopic joint 513 can be used at the end of the slide rail 51, which is used to pull out the telescopic joint 513 from the slide rail 51 when needed to extend the length of the slide rail 51, so as to facilitate the placement of the slide rail tray 6 and move the used surgical instruments out of the operating area along with the slide rail tray 6, thereby increasing the operation and storage space; similarly, the first bracket 52 or the second bracket 53 can also adopt a telescopic rod to facilitate the rapid adjustment of the relative position of the slide rail system 5. For example, the end of the telescopic rod is threadedly connected to the slide rail system 5 to achieve a detachable connection.

[0063] Furthermore, a pulley 406 may be provided at the bottom of the tripod 405 and the second bracket 53 , and the pulley 406 may be a universal wheel for improving the flexibility of overall carrying and movement.

[0064] Furthermore, the slide rail system 5 includes two slide rails 51, and the two sides of the slide rail tray 6 are respectively provided with ears 601 that slide with the slide rails 51 on the same side; for example: a plurality of U-shaped third brackets 54 are used to connect the two slide rails 51 to provide support points for the slide rails 51, and the first bracket 52, the second bracket 53, the third bracket 54 and the slide rail 51 are all made of steel structure, and the slide rail tray 6 is rectangular, and the slide rails 51 are hooked by ears 601 on both sides, so that the slide rail tray 6 is hung on the slide rail 51 and can slide along the slide rail 51.

[0065] Furthermore, the connection between the inclined section 511 and the horizontal section 512 of the slide rail 51 may be in an arc shape to improve the stability of the turning of the slide rail tray 6 .

[0066] Further, such as Fig. 9 As shown, in order to prevent it from falling off during sliding, the ear 601 is provided with a notch 602 that slides with the slide rail 51. The notch 602 opens downward and is narrow at the top and wide at the bottom, which can increase the contact area and friction resistance between the ear 601 and the slide rail 51, thereby preventing the slide rail tray 6 from sliding too fast on the slide rail 51 and causing it to fall off.

[0067] Furthermore, it includes a plurality of slide trays 6, wherein the front bottom of the slide tray 6 is provided with an inclined surface 603, the rear and top of the slide tray 6 are open, and along the sliding direction of the slide tray 6, the rear slide tray 6 can be nested and stacked on top of the previous slide tray 6, and the bottom of the rear slide tray 6 cooperates with the inclined surface 603 of the previous slide tray 6; for example: when there is already a previous slide tray 6 in the sterile area and the rear slide tray 6 in the operation area needs to be moved out, the rear slide tray 6 can be slightly lifted upwards to embed the rear slide tray 6 from the opening at the rear of the previous slide tray 6 into the interior of the previous slide tray 6 and stacked on top of the previous slide tray 6, and due to the setting of the inclined surface 603, as Fig. 9 As shown, the bottom of the rear slide tray 6 cooperates with the inclined surface 603 of the front slide tray 6, so that a certain space is left between the two slide trays 6 for storing surgical instruments to avoid crushing the surgical instruments when stacking; similarly, when the front slide tray 6 is not used, the rear slide tray 6 can be manually lifted and slid above it, thereby saving space and avoiding violating the sterility principle when lifting the slide tray 6 for stacking.

[0068] Furthermore, the inner surface of the slide tray 6 is provided with a plurality of protrusions 604 , for example, the protrusions 604 may be circular, so as to reduce the sliding of the instrument, especially when the rear of the slide tray 6 is open, to prevent the instrument from sliding out of the slide tray 6 .

[0069] Furthermore, a large surgical drape is provided on the seat body. The large surgical drape is a commonly used surgical material. Those skilled in the art may understand its specific structure, so it is not shown in the figure. The large surgical drape is laid to improve hygiene.

[0070] Furthermore, a small surgical sheet is provided between the slide rail 51 and the slide rail tray 6. The large surgical sheet is a commonly used surgical material, and those skilled in the art may understand its specific structure, so it is not shown in the figure. The small surgical sheet may be laid on the two slide rails 51 first, and then the slide rail tray 6 may be placed on the small surgical sheet to avoid violating the sterility principle when lifting the slide rail tray 6 for stacking. At the same time, the friction between the slide rail tray 6 and the slide rail 51 may be strengthened to prevent the slide rail tray 6 from sliding too fast on the slide rail 51 and falling off.

[0071] In summary, the specific operations of the lithotomy position surgery chair may include:

[0072] When the operation begins, a large surgical sheet is placed on the lithotomy surgery chair. The surgeon 2 adjusts his position after sitting down. When surgical instruments are needed, the instrument nurse places the surgical instruments in the slide tray 6, and a small surgical sheet is placed under the slide tray 6. The slide tray 6 is placed on the slide rail 51 from above the patient's 1 knees. The slide tray 6 loaded with surgical instruments is transported along the track to the left side of the surgeon 2. The surgeon 2 pulls the slide tray 6 to the slide rail 51 in the center in front of the panel 402, completing the transfer of the instruments and building an operating platform. The discarded slide tray 6 can carry dirt and transfer it to the right side of the surgeon 2 and move it out of the operating area. This improves the comfort and convenience of the surgeon's 2 operation while ensuring the patient's 1 position, expands the operating space, and realizes the rapid and accurate transfer of instruments during the operation, while avoiding the contamination of the instruments during the transfer process, thereby saving the surgeon's 2 physical strength and making the operation more efficient. Example

[0073] like Fig.10 As shown, another preferred embodiment of the lithotomy position surgery chair of the utility model is different from Example 1 in that: the first bracket 52 is not provided, the footrest 405 is not extended, and only the second bracket 53 is provided, so it can be improved on the basis of the circular swivel chair commonly used in the operating room: a panel 402 is added to obtain the seat body 4, so as to prevent the slide rail system 5 from affecting the center of gravity of the seat body 4 and facilitate the height of the seat body 4. Because the seat body 4 has the rotation function of a circular swivel chair, the angle adjustment of the seat body 4 is convenient, so that the doctor can better observe the operating area, and the seat body 4 and the slide rail system 5 can also be used and stored separately to increase flexibility. Example

[0074] like Fig.11As shown, another preferred embodiment of the lithotomy surgery chair of the utility model is shown. The difference between the lithotomy surgery chair and Example 1 is that a slot 408 is provided on the seat body 4. For example, the slot 408 is set on the footrest 405 on the same side as the slide rail 51. The slot 408 is used to connect with the lithotomy surgery bed 3. If necessary, it can be connected with the bracket 301 of the surgery bed 3 to achieve a more secure connection.
