Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a device for adjusting the position of the affected limb after breast cancer surgery. Background Technology

[0002] Breast cancer is a condition in which breast epithelial cells proliferate uncontrollably under the influence of various carcinogenic factors. Early symptoms often include breast lumps, nipple discharge, and enlarged axillary lymph nodes. In later stages, distant metastasis of cancer cells can lead to multi-organ complications, directly threatening the patient's life.

[0003] For patients who have undergone axillary lymph node dissection, it is common clinical practice to place a pillow or soft cushion under the affected limb post-surgery. The angle is estimated, and the affected limb is generally elevated appropriately at night while sleeping, usually at an angle of about 30-40 degrees, with the hand higher than the elbow, and the elbow higher than the heart, to facilitate blood and lymphatic drainage. This can prevent the patient from experiencing lymphedema due to prolonged limb drooping.

[0004] A Chinese patent discloses a limb positioning device after axillary lymph node dissection for breast cancer. A scapular fixation pad is placed under the patient's back for relative fixation, reducing the possibility of the posterior and forearm elevation pads falling off the affected limb. Furthermore, when the patient's posterior arm is placed on the posterior arm elevation pad and the forearm on the forearm elevation pad after axillary lymph node dissection, the hand is positioned higher than the elbow, and the elbow is higher than the heart, facilitating blood and lymphatic drainage and preventing lymphedema caused by prolonged limb drooping.

[0005] However, when the above-mentioned body position adjustment device is used for patients of different weights, the hands of the obese patients are level with or below the elbows, and the arms of the obese patients may be difficult to fit into the arm placement slot, while the hands of the thinner patients may be too high above the elbows, and the arms of the thinner patients are prone to moving in the arm placement slot, which is not conducive to the patient's recovery.

[0006] Therefore, there is an urgent need to design a limb positioning device after breast cancer surgery to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a limb positioning adjustment device after breast cancer surgery, which has the advantages of adjusting the height of the limb adjustment pad and the width of the limb placement cavity according to the patient's weight, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the specific technical solution of the postoperative limb position adjustment device for breast cancer is as follows:

[0009] A limb positioning device after breast cancer surgery includes a scapular fixation pad and an limb adjustment pad. The scapular fixation pad is placed under the patient's back. The scapular fixation pad is connected to the limb adjustment pad, and the limb adjustment pad can slide relative to the scapular fixation pad to adjust the height of the limb adjustment pad. The limb adjustment pad has a limb placement cavity, and the width of the limb placement cavity is adjusted according to the height of the limb adjustment pad. When the height of the limb adjustment pad increases, the width of the limb placement cavity increases synchronously, and when the height of the limb adjustment pad decreases, the width of the limb placement cavity decreases synchronously.

[0010] Furthermore, the affected limb adjustment pad includes a support sleeve and an affected limb pad. The support sleeve is fitted over the affected limb pad, and the affected limb pad can slide relative to the support sleeve.

[0011] Furthermore, an electric push rod is fixedly connected to the support sleeve, and the output end of the electric push rod is fixedly connected to the affected limb pad. The electric push rod adjusts the height of the affected limb pad.

[0012] Furthermore, the affected limb pad includes a fixed pad and two sliding pads, which are located at both ends of the fixed pad. The two sliding pads and the fixed pad together form the affected limb placement cavity. The two sliding pads can move towards or away from the fixed pad to change the width of the affected limb placement cavity.

[0013] Furthermore, a sliding cavity is provided on the fixing pad, and the fixing pad is slidably connected to the sliding pad through the sliding cavity.

[0014] Furthermore, the sliding pad has an inclined surface that abuts against the support sleeve. When the height of the affected limb pad increases, the two sliding pads slide in opposite directions, increasing the width of the affected limb placement cavity. When the height of the affected limb pad decreases, the two sliding pads slide towards each other, decreasing the width of the affected limb placement cavity.

[0015] Furthermore, a spring is provided between the sliding pad and the fixed pad, with both ends of the spring being fixedly connected to the sliding pad and the fixed pad, respectively.

[0016] Furthermore, the affected limb adjustment pad includes a posterior arm adjustment pad and an forearm adjustment pad, which are hinged together. The end of the posterior arm adjustment pad away from the forearm adjustment pad is hinged to the scapular fixation pad.

[0017] Furthermore, the top surfaces of both the rear arm elevation pad and the forearm elevation pad are inclined upwards along the first direction.

[0018] Furthermore, the top surfaces of the posterior arm elevation pad and the forearm elevation pad have the same inclination angle, and the top surface of the forearm elevation pad is higher than the top surface of the posterior arm elevation pad.

[0019] This invention has the following advantages: the height of the limb adjustment pad can be adjusted according to the patient's weight, and the width of the limb placement cavity can be adjusted simultaneously, so that the patient's hand is always higher than the elbow, and the elbow is higher than the heart, which is conducive to the return of blood or lymph fluid, and the limb placement cavity can always accommodate the patient's limb.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0027] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This invention describes a device for adjusting the position of the affected limb after breast cancer surgery.

[0028] The body positioning adjustment device includes a scapular fixation pad 1 and an affected limb adjustment pad 2. The scapular fixation pad 1 is placed under the patient's back. The scapular fixation pad 1 is connected to the affected limb adjustment pad 2, which is used to support the patient's limb. Preferably, the scapular fixation pad 1 and the affected limb adjustment pad 2 are hinged by a pin, so that the angle between the scapular fixation pad 1 and the affected limb adjustment pad 2 can be easily adjusted to accommodate different patients. In other embodiments of this utility model, the scapular fixation pad 1 and the affected limb adjustment pad 2 can also be rotatably connected by a rotating shaft, so that the angle between the scapular fixation pad 1 and the affected limb adjustment pad 2 can be adjusted. When the angle between the scapular fixation pad 1 and the affected limb adjustment pad 2 does not need to be adjusted, the scapular fixation pad 1 and the affected limb adjustment pad 2 can also be fixedly connected.

[0029] Preferably, the affected limb adjustment pad 2 includes a hindarm adjustment pad 3 and a forearm adjustment pad 4. The hindarm adjustment pad 3 is used to support the patient's hindarm, and the forearm adjustment pad 4 is used to support the patient's forearm. In other embodiments of this utility model, the patient adjustment pad can also be divided according to other needs, and the patient adjustment pad can also be a whole, as long as it can meet the support effect for the patient's limb.

[0030] Preferably, the posterior arm adjustment pad 3 and the forearm adjustment pad 4 are hinged together, and the end of the posterior arm adjustment pad 3 away from the forearm adjustment pad 4 is hinged to the scapular fixation pad 1, so as to adjust the angle between the posterior arm adjustment pad 3 and the forearm adjustment pad 4 and the angle between the posterior arm adjustment pad 3 and the scapular fixation pad 1. In other embodiments of this utility model, the posterior arm adjustment pad 3 and the forearm adjustment pad 4, as well as the scapular fixation pad 1 and the affected limb adjustment pad 2, can also be rotatably connected by a pivot. When the angle between the posterior arm adjustment pad 3 and the forearm adjustment pad 4, and the angle between the scapular fixation pad 1 and the affected limb adjustment pad 2, do not need to be adjusted, the posterior arm adjustment pad 3 and the forearm adjustment pad 4 can also be fixedly connected, and the scapular fixation pad 1 and the affected limb adjustment pad 2 can also be fixedly connected.

[0031] A first hinge plate is connected to the rear arm adjusting pad 3, and a second hinge plate is connected to the forearm adjusting pad 4. The first and second hinge plates are hinged together to adjust the angle between the rear arm adjusting pad 3 and the forearm adjusting pad 4, as well as the angle between the rear arm adjusting pad 3 and the scapular fixing pad 1. Preferably, the rear arm adjusting pad 3 and the forearm adjusting pad 4 are provided with sliding grooves. The rear arm adjusting pad 3 is slidably connected to the first hinge plate through the sliding groove, and the forearm adjusting pad 4 is slidably connected to the second hinge plate through the sliding groove. This allows adjustment by changing the extension of the first hinge plate. The length of the posterior arm adjusting pad 3 and the length of the forearm adjusting pad 4 extending beyond the second hinge plate are adjusted to regulate the distance between the posterior arm adjusting pad 3 and the forearm adjusting pad 4, thereby accommodating limbs of different lengths. In other embodiments of this utility model, a groove may be provided only on the posterior arm adjusting pad 3, while the forearm adjusting pad 4 is fixedly connected to the second hinge plate. Alternatively, a groove may be provided only on the forearm adjusting pad 4, while the posterior arm adjusting pad 3 is fixedly connected to the first hinge plate. The goal is simply to achieve an adjustable distance between the posterior arm adjusting pad 3 and the forearm adjusting pad 4.

[0032] Specifically, the top surfaces of both the posterior arm elevation pad and the forearm elevation pad are tilted upwards along the first direction, so that the patient's hand is higher than the elbow, and the elbow is higher than the heart, which facilitates the return of blood or lymph fluid and prevents lymphedema caused by prolonged limb drooping.

[0033] Preferably, the top surface of the rear arm elevation pad and the top surface of the forearm elevation pad have the same inclination angle, and the top surface of the forearm elevation pad is higher than the top surface of the rear arm elevation pad. In other embodiments of the utility model, the inclination angles of the top surface of the rear arm elevation pad and the top surface of the forearm elevation pad may also be different, as long as it can be ensured that the top surface of the forearm elevation pad is higher than the top surface of the rear arm elevation pad.

[0034] Specifically, both the scapular fixation pad 1 and the affected limb adjustment pad 2 can be covered with a soft material layer.

[0035] Current posture adjustment devices have limitations when dealing with patients of different body sizes. For overweight patients, the hand may be level with or below the elbow, and the arm may be difficult to fit into the arm placement slot. For underweight patients, the hand may be too high above the elbow, and the arm may move easily within the arm placement slot, which is not conducive to the patient's recovery.

[0036] Therefore, the body position adjustment device includes a scapular fixation pad 1 and an affected limb adjustment pad 2. The scapular fixation pad 1 is used to place under the patient's back. The scapular fixation pad 1 is connected to the affected limb adjustment pad 2. The affected limb adjustment pad 2 can slide relative to the scapular fixation pad 1 to adjust the height of the affected limb adjustment pad 2. The affected limb adjustment pad 2 is provided with an affected limb placement cavity 23. The width of the affected limb placement cavity 23 is adjusted according to the height of the affected limb adjustment pad 2. When the height of the affected limb adjustment pad 2 increases, the width of the affected limb placement cavity 23 increases synchronously. When the height of the affected limb adjustment pad 2 decreases, the width of the affected limb placement cavity 23 decreases synchronously.

[0037] When using the body position adjustment device for obese patients, the height of the affected limb adjustment pad 2 can be increased so that the obese patient's hand is higher than the elbow, which is conducive to the return of blood or lymph. At the same time as increasing the height, the width of the affected limb placement cavity 23 is increased simultaneously, so that the obese patient's arm can be placed in the patient placement cavity.

[0038] When using the body position adjustment device for thinner patients, the height of the affected limb adjustment pad 2 can be reduced so that the thinner patient's hand is higher than the elbow and the tilt angle is kept within the range of motion. At the same time as reducing the height, the width of the affected limb placement cavity 23 is reduced simultaneously so that the patient placement cavity fits the patient's arm.

[0039] The affected limb adjustment pad 2 includes a support sleeve 21 and an affected limb pad 29. The support sleeve 21 is fitted over the affected limb pad 29, and the affected limb pad 29 can slide relative to the support sleeve 21 to adjust the height of the affected limb pad 29 according to the patient's body size. Specifically, an electric push rod 28 is fixedly connected to the support sleeve 21. The output end of the electric push rod 28 is fixedly connected to the affected limb pad 29. The electric push rod 28 adjusts the height of the affected limb pad 29 by extending or retracting the output end of the electric push rod 28, thereby increasing or decreasing the height of the affected limb pad 29.

[0040] Furthermore, the affected limb pad 29 includes a fixed pad 24 and two sliding pads 22. The two sliding pads 22 are located at both ends of the fixed pad 24, and the two sliding pads 22 and the fixed pad 24 form the affected limb placement cavity 23. The two sliding pads 22 can move towards or away from the fixed pad 24 to change the width of the affected limb placement cavity 23. Specifically, the sliding pads 22 are provided with inclined surfaces 27. The inclined surfaces 27 of the sliding pads 22 are always in contact with the support sleeve 21. When the height of the affected limb pad 29 increases, the two sliding pads 22 slide away from each other, increasing the width of the affected limb placement cavity 23. When the height of the affected limb pad 29 decreases, the two sliding pads 22 slide towards each other, decreasing the width of the affected limb placement cavity 23. In other embodiments of this utility model, other structural combinations can also be used to make the width of the affected limb placement cavity 23 change synchronously when the height of the affected limb pad 29 changes.

[0041] Preferably, the fixing pad 24 has a sliding cavity, and the fixing pad 24 is slidably connected to the sliding pad 22 through the sliding cavity. In other embodiments of this utility model, the fixing pad 24 and the sliding pad 22 can also be slidably connected through other structural cooperation.

[0042] Specifically, a spring 25 is provided between the sliding pad 22 and the fixed pad 24. The two ends of the spring 25 are fixedly connected to the sliding pad 22 and the fixed pad 24 respectively, so that the sliding pad 22 and the support sleeve 21 are always in contact through the spring 25.

[0043] Preferably, the sliding pad 22 has an opening 26, one end of the spring 25 is connected to the inner wall of the opening 26, and the other end is fixedly connected to the support sleeve 21.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
