Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a mechanically linked rectal cancer surgery position maintaining device and an adjustment method. Background Art

[0002] During rectal cancer surgery, patients are often required to maintain the lithotomy position or supine position according to different conditions. Correct maintenance of the lithotomy position or supine position is conducive to the smooth progress of the operation and reduces the patient's pain.

[0003] Specifically, the lithotomy position mainly involves lifting the patient's legs, while the patient's upper limbs lie flat on the operating table, so that the patient's perineum and anus can be fully exposed, thereby facilitating anorectal surgery.

[0004] Although the existing lithotomy position maintaining device can enable the patient to maintain the lithotomy position, being in the lithotomy position does not mean that the patient's perineum is fully exposed. Fine-tuning is required according to the patients of different body shapes. At this time, the patient's legs must be separated from the leg rests before the height of the leg rests and the support rods can be adjusted. This results in the patient having to lift his legs several times during use to cooperate with the medical staff in determining whether the lithotomy position in this state is convenient for surgery, which causes excessive consumption of the patient's physical energy and is not conducive to the smooth progress of the surgery.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0052] See also Figures 1 to 9 In an embodiment of the present invention, a mechanically linked rectal cancer surgery position maintaining device is arranged on an operating table 1, and includes: a flip member 3 and a support member 4, a pushing structure, a power component and an adjustment component.

[0053] The flip member 3 and the support member 4 are arranged on the operating table 1, and the support member 4 is used to support the patient's legs;

[0054] The pushing structure is connected to the flip member 3, and the pushing structure can drive the flip member 3 to deflect upward. The pushing structure includes a turntable 14 rotatably mounted on the adjustment assembly, and two groups of connecting shafts 16 are symmetrically arranged on the turntable 14, one group of the connecting shafts 16 is connected to the flip member 3 through a second connecting rod 15, and the other group of the connecting shafts 16 is provided with a first connecting rod 13, and a groove wheel 11 is rotatably mounted on one end of the first connecting rod 13 away from the connecting shaft 16. Specifically, the two groups of the connecting shafts 16 are rotatably connected to the first connecting rod 13 and the second connecting rod 15 respectively;

[0055] The pushing structure also includes a connecting plate 12 arranged on the adjusting assembly. The connecting plate 12 is provided with a guide groove. The groove wheel 11 can roll in the guide groove. The guide groove includes a first horizontal groove 1201 and a vertical groove 1202 arranged on the connecting plate 12.

[0056] In the initial state, the flip member 3 is in the same plane as the upper surface of the operating bed 1 , so that in this state, the operating bed 1 can be used for other types of surgeries, thereby improving its applicability.

[0057] During use, when the power component is activated, it can drive the groove wheel 11 to move, so that one end of the first connecting rod 13 is pulled, and the turntable 14 can rotate at this time to drive the two sets of connecting shafts 16 to make circular motion. At the same time, the connecting shaft 16 can support the flip member 3 through the second connecting rod 15, so that the flip member 3 can deflect upward along its rotation center until it is initially in a vertical state, thereby forming a stop state for the patient's shoulder. On the one hand, when the subsequent adjustment component is activated, the flip member 3 can be used to drive the patient's body to move relative to the operating table 1, so that the patient has a more standard lithotomy position, so that the operation can be carried out more smoothly, while improving the success rate of the operation. On the other hand, it prevents the patient's body from sliding relative to the operating table 1 when the patient's legs are lifted, thereby improving the stability of the patient's body when entering the lithotomy position.

[0058] In order to achieve the above effect, the connecting line of the two sets of connecting shafts 16 should pass through the rotating shaft of the rotating disk 14 , and the connecting shafts 16 are located at an eccentric position of the rotating disk 14 .

[0059] It should be noted that when the patient suffers from anorectal diseases, he has a strong perception of the bending of his hips, which makes the patient resist the bending of his hips when the patient's legs are lifted. At this time, when the patient's legs are lifted, the patient's body tends to tense up, causing his body to have a tendency to slide away from the lifted side relative to the operating bed 1.

[0060] See also Figures 4 to 6 The pushing structure is connected with an abutment shaft 10, and the abutment shaft 10 is coaxially arranged with the groove wheel 11. The power assembly is arranged on the operating bed 1, and the power assembly is connected with a driving plate 9. The driving plate 9 cooperates with the abutment shaft 10 to drive the turntable 14 to move. The driving plate 9 is provided with an inclined surface 901 and a straight surface 902 on the side facing the abutment shaft 10. When the driving plate 9 moves, the abutment shaft 10 and the groove wheel 11 can be driven to move along the first horizontal groove 1201, and when the groove wheel 11 moves into the vertical groove 1202, the abutment shaft 10 abuts against the straight surface 902.

[0061] When the flip member 3 is in a horizontal state, the sheave 11 is at one end of the first horizontal groove 1201 away from the vertical groove 1202, and with the action of the power assembly, the drive plate 9 can move toward the support member 4, and at this time, the inclined surface 901 is in a state of abutting against the abutment shaft 10, thereby driving the abutment shaft 10 and the sheave 11 to move synchronously. In this process, the first horizontal groove 1201 has a guiding effect on the sheave 11, so that the sheave 11 and the abutment shaft 10 can move along the length direction of the first horizontal groove 1201, and drive the turntable 14 to rotate to lift the flip member 3, and when After the groove wheel 11 moves to the end of the first horizontal groove 1201, the driving plate 9 can continue to move. At this time, under the action of the inclined surface 901, the groove wheel 11 and the abutment shaft 10 can move along the vertical groove 1202. At the same time, the abutment shaft 10 slides relative to the inclined surface 901 until the groove wheel 11 moves to the end of the vertical groove 1202, and the abutment shaft 10 just abuts against the straight surface 902. At this time, although the driving plate 9 can continue to move, the positions of the abutment shaft 10 and the groove wheel 11 will not change, so that the flip member 3 can maintain a vertical state, that is, it has the effect of locking the flip member 3.

[0062] See also Figure 3-4 , Figure 7 The power assembly includes a motor 6 fixedly mounted on the operating bed 1, a screw rod 7 is connected to the output shaft of the motor 6, a threaded sleeve 8 is provided on the screw rod 7, and the threaded sleeve 8 is connected to the driving plate 9;

[0063] The driving plate 9 and the support member 4 are connected via an inclined rod 28. When the power assembly is actuated, the flip member 3 and the support member 4 can be driven to act in turn. Specifically, a hysteresis groove 2801 is provided at one end of the inclined rod 28 away from the support member 4, and the hysteresis shaft 27 connected to the driving plate 9 can slide in the hysteresis groove 2801.

[0064] When in use, the motor 6 is controlled to work. At this time, the output shaft of the motor 6 can drive the screw 7 to rotate, and the threaded sleeve 8 that is threadedly matched with the screw 7 can move along the length direction of the screw 7, thereby driving the drive plate 9 and the hysteresis shaft 27 to move. Among them, the threaded connection between the screw 7 and the threaded sleeve 8 has a labor-saving effect on the one hand, so that the load borne by the motor 6 is lower. On the other hand, the threaded connection has a self-locking effect, so that after the motor 6 is powered off, the relative position of the threaded sleeve 8 relative to the screw 7 will not change, thereby improving the stability of the drive plate 9 and the hysteresis shaft 27 when the motor 6 is powered off.

[0065] Furthermore, when the threaded sleeve 8 drives the driving plate 9 to move, when the inclined surface 901 cooperates with the abutting shaft 10, the hysteresis shaft 27 is in the hysteresis groove 2801. At this time, the inclined rod 28 only changes its inclination angle, and does not act on the support member 4. That is, when the flip member 3 moves, the support member 4 can remain stationary, and when the flip member 3 flips to a vertical state, the hysteresis shaft 27 moves to the end of the hysteresis groove 2801. At this time, the hysteresis shaft 27 acts on the inclined rod 28 and drives the support member 4 to move upward to lift the patient's legs and enable the patient to enter the preparatory state of the lithotomy position. At this time, the patient's position is roughly in the lithotomy position, and because the flip member 3 can stop the patient's shoulders at this time, it prevents the patient's body from sliding relative to the operating bed 1 when the legs are lifted.

[0066] Through the above arrangement, when the motor 6 is working, the drive plate 9 can be driven to move through the cooperation of the screw rod 7 and the threaded sleeve 8, and the first connecting rod 13 can be pulled. Under the action of the turntable 14 and the second connecting rod 15, the flip member 3 first performs a flipping action, and then the flip member 3 can be locked, so that it has higher stability in the vertical state, ensuring that when the patient's legs are lifted, the patient's body will not slide relative to the operating bed 1. Thereafter, the drive plate 9 can continue to move and drive the support member 4 to move upward through the inclined rod 28 to lift the patient's legs, so that the patient enters the preparatory state of the lithotomy position.

[0067] See also Figure 3 , Figure 7-8 The adjusting component is connected to the flip member 3 and the inclined rod 28, and the adjusting component can make the support member 4 move downward along the vertical direction of the space when driving the flip member 3 to move toward the support member 4;

[0068] The adjustment assembly includes a moving member 2 slidably mounted on the operating bed 1, the moving member 2 is rotatably connected to the flip member 3, and an adjustment plate 17 is connected to the moving member 2, the adjustment plate 17 is connected to an electric telescopic rod 18 provided on the operating bed 1, wherein the adjustment plate 17 is rotatably connected to the turntable 14 and fixedly connected to the connecting plate 12;

[0069] The driving plate 9 is also provided with a slide groove 903, in which a sliding connection member 26 rotatably connected to the hysteresis shaft 27 is slidably installed;

[0070] The adjustment assembly also includes a follow-up structure connected to the adjustment plate 17 and the hysteresis shaft 27, and the follow-up structure includes a lifting plate 24 connected to the adjustment plate 17 through a telescopic rod. The lifting plate 24 is provided with a second horizontal groove 2401 along its length direction. The second convex shaft 25 rotatably mounted on the sliding connection 26 can roll in the second horizontal groove 2401, so that when the driving plate 9 moves, the height of the sliding connection 26 can be kept constant, thereby improving the stability of the support member 4 during the rising process.

[0071] The follower structure is rotatably mounted with a first convex shaft 21. Specifically, the telescopic rod comprises two sets of guide shafts 19 fixedly connected to the adjustment plate 17 and two sets of guide sleeves 20 fixedly connected to the lifting plate 24. The guide sleeves 20 are slidably fitted with the guide shafts 19.

[0072] The first convex shaft 21 is rotatably mounted between the two sets of guide sleeves 20;

[0073] An inclined groove 23 is formed on the side plate 22 fixedly mounted on the operating bed 1 , and the first convex shaft 21 can roll in the inclined groove 23 .

[0074] When the patient enters the preparatory state of the lithotomy position, the medical staff can make secondary adjustments to the patient's position according to the lithotomy position in this state, specifically:

[0075] By controlling the electric telescopic rod 18, the moving part 2 can be driven to move, and at this time the moving part 2 can drive the flipping part 3 to move toward the supporting part 4, so that the patient's body can be driven to move toward the supporting part 4. In this process, the abutting shaft 10 can move along the flat surface 902, and the position of the groove wheel 11 relative to the vertical groove 1202 remains unchanged, that is, the flipping part 3 is still in a locked state to ensure the pushing of the patient's shoulder, and under the action of the telescopic rod, the adjusting plate 17 can drive the lifting plate 24 to move, and as the movement proceeds, the first convex shaft 21 and the tilting plate 24 are moved. With the cooperation of the groove 23, the lifting plate 24 can move downward. At this time, under the action of the second horizontal groove 2401, the second convex shaft 25, and the sliding connection 26, the hysteresis shaft 27 can follow the sliding connection 26 to move downward along the length direction of the slide groove 903, thereby causing the support member 4 to move downward. That is, in the process of the patient's body being pushed toward the support member 4, the height of the support member 4 will also decrease. In this process, the curvature of the patient's hips can be changed, so that the patient's perineum and anus can be fully exposed, thereby improving the surgical field of view and further improving the success rate of the operation to a certain extent.

[0076] Through the above-mentioned arrangement, after the patient enters the preparatory state of the lithotomy position, the medical staff can further make secondary fine adjustments to the patient's position according to the patient's position, thereby appropriately adjusting the curvature of the patient's hips, so that the patient's perineum and anus are fully exposed, the surgical field of view is improved, and the success rate of the operation is further improved to a certain extent.

[0077] See also Fig. 9 The support member 4 is connected to a support rod 5 slidably mounted on the operating bed 1, and one end of the support rod 5 away from the support member 4 is connected to a transverse plate 29, and the transverse plate 29 is rotatably connected to the oblique rod 28;

[0078] The support rod 5 is also provided with a collar 30, and the collar 30 is provided with two sets of limiting grooves 3001;

[0079] The elastic limiting structure arranged on the transverse plate 29 is adapted to the limiting groove 3001, and the elastic limiting structure includes a bracket 31 slidably arranged through the transverse plate 29, and the bracket 31 is connected to the transverse plate 29 through a columnar spring 32;

[0080] A limiting shaft 33 is also rotatably mounted on the bracket 31 , and the limiting shaft 33 is adapted to the limiting groove 3001 .

[0081] In this embodiment, the support member 4 has two position states. One is that the support member 4 is on the upper part of the operating bed 1. At this time, the patient places his legs on the support member 4, and the support member 4 can lift the patient's legs. The second is that the support member 4 is on the side of the operating bed 1. At this time, the distance between the two support members 4 is larger, so that it is convenient for the patient to lie on the operating bed 1 from the end of the operating bed 1, and in the event of an accident during the operation, by switching the support member 4 to this state, it is convenient for medical staff to find the source of the accident.

[0082] In detail, by stepping on the bracket 31, the limit shaft 33 can be separated from the limit groove 3001. At this time, the cylindrical spring 32 can be further stretched. At the same time, the support rod 5 is rotated to switch the position of the support member 4 and release the bracket 31. The limit shaft 33 can cooperate with another limit groove 3001 to achieve re-locking of the support member 4.

[0083] As an embodiment of the present invention, a method for adjusting the patient's body position using the mechanical linkage type rectal cancer surgery body position maintaining device is also proposed, comprising the following steps:

[0084] Step 1: The patient lies flat on the operating table 1, with the patient's lower legs placed on the support 4;

[0085] Step 2: Control the power assembly to move, so that the driving plate 9 moves. At this time, the driving plate 9 cooperates with the abutment shaft 10, and the push structure is first moved to turn the flip member 3 to stop the patient's shoulder;

[0086] Step 3: The power assembly continues to move, driving the support member 4 to move upward through the inclined rod 28;

[0087] Step 4: Control the movement of the adjustment component so that the flip member 3 drives the patient's body to move toward the support member 4, and at the same time the height of the support member 4 decreases, and at this time the curvature of the patient's hips increases;

[0088] Step 5: Perform the operation. After the operation is completed, control the adjustment component and the power component to move in sequence, and move the patient out of the operating table 1.
