Patent Application
20210205163
This application describes examples of apparatuses, methods, and systems for the positioning of a patient for proper visualization and access of tissues for injection or treatment.
Traditional therapeutic and diagnostic surgical procedures for pathologies located within the body can cause significant trauma to the intervening tissues and potentially the target tissue site. Such procedures often require a long incision, extensive muscle stripping, prolonged retraction of tissues, denervation and devascularization of tissue. Such procedures may require operating room time of several hours followed by several weeks of post-operative recovery time due to the destruction of tissue during the surgical procedure. In some cases, these invasive procedures lead to permanent scarring and pain that can be more severe than the pain leading to the surgical intervention.
The development of percutaneous procedures has yielded a major improvement in reducing recovery time and post-operative pain because minimal dissection of tissue, such as muscle tissue, is required. For example, minimally invasive surgical techniques are desirable for orthopedic applications due to the need for access to locations within the body and the danger of damage to vital intervening tissues. While developments in minimally invasive surgery are steps in the right direction, there remains a need for further development in minimally invasive surgical instruments and methods.
Treatment of internal tissue sites, such as the treatment of an orthopedic joint, often requires proper positioning for visualization of and access to the target internal tissues for imaging and injections. Currently in the field, it is often difficult for a surgeon to access specific areas of the anatomy and thus they often fail to visualize and diagnose completely. However, when a patient is properly positioned, a surgeon or doctor may be able to access specific areas of the anatomy for proper diagnosis. With proper positioning, typically tight or inaccessible tissue sites within the patient can be opened up for visualization and access. Additionally, orthopedic joints must be properly positioned and stabilized for access to the desired internal tissue site, for proper visualization of the desired internal tissue site and to prevent injury to the patient. Consequently, there is need for improved devices and methods for positioning of a patient to open up areas for visualization and access to an internal tissue site.

In some examples, the joint positioning device 5 includes a patient support 100 and a vertical pillar 200. In some examples, the joint positioning device 5 may be positioned on a medical examination table 10 widthwise, as shown in
In certain examples, the patient support 100 may be a substantially flat board or platform. The patient support 100 may be substantially rigid. In other examples, the patient support 100 may be flexible. In some examples, the patient support 100 may be made of plastic, metal, foam, for example closed-cell foams, or other suitable material. In certain examples, the metal may be stainless steel, chrome, or any suitable metal that is corrosion-resistant and readily cleanable.
The patient support 100 may be positioned to lay flat on the surface of a medical examination table 10. In some examples, the patient support 100 may be substantially rectangular, as shown in
In examples, the patient support 100 may be dimensioned to fit an examination medical table 10. In some examples, the patient support 100 may be adjustable such that the length or width may be adjusted.
While the dimensions of the patient support 100 may vary, in certain examples the length of the patient support 100 ranges from about 10 inches to about 100 inches, such as about 59.5 inches to about 75.5 inches, including about 20 inches to about 60 inches. For example, 26 inches or 33 inches. While the dimensions of the patient support 100 may vary, in certain examples the width of the patient support 100 ranges from 1 inch to 30 inches, including 2 inches to 20 inches, and including 3 inches to 5 inches. While the dimensions of the patient support 100 may vary, in certain examples the thickness or height of the patient support 100 ranges from 0.1 inches to 5 inches, such as 0.3 inches to 3 inches, including 0.5 inches to 1.5 inches.
The patient support 100 may have a longitudinal axis and lateral axis, where the longitudinal axis and lateral axis are substantially perpendicular from each other. The longitudinal axis may be substantially parallel to the length of the patient support 100. The lateral axis may be substantially parallel to the width of the patient support 100.
The medical examination table 10 may have a longitudinal axis and lateral axis, where the longitudinal axis and lateral axis are substantially perpendicular from each other. The longitudinal axis may be substantially parallel to the length of the medical examination table 10. The lateral axis may be substantially parallel to the width of the medical examination table 10.
Turning to
In some examples, the patient support 100 may have a series of leg holes 112, as shown in
Furthermore, the patient support 100 may include a series of leg holes 112 along the length of the patient support 100. The series of leg holes 112 allows for the legs 104 to be adjusted and positioned along the length of the patient support 100, such that the distance between the legs 104 may be adjusted. In some examples, the distance between the legs 104 to correspond to the width or length of the medical examination table 10. In some examples, the distance between the legs 104 may be adjusted to correspond to the length of width of a standard medical examination table 10 or a variety of different sized medical examination tables 10.
The legs 104 may immobilize the patient support 100 relative to the medical examination table 10 in a lateral or longitudinal direction. The legs 104 may laterally immobilize the joint positioning device 5 to the medical examination table 10.
For example, in some examples, two legs 104 are positioned at the distal end of the patient support 100. The patient support 100 may then be placed widthwise or lengthwise on a medical examination table 10. Two other legs 104 may be adjusted and positioned at the proximal end of the patient support 100, corresponding to the width or length of the medical examination table 10. This will immobilize the patient support 100 such that it cannot be shifted in a lateral direction, relative to the lateral or longitudinal axis of the medical examination table 10. The legs 104 may immobilize the patient support 100 relative to the medical examination table 10 in a lateral or longitudinal direction. The legs 104 may laterally immobilize the joint positioning device 5 to the medical examination table 10.
For example, if a pediatric medical examination table 10 is used, which has a smaller width and length than a standard medical examination table 10, the one or more legs 104 may be adjusted such that they are positioned in a different set of leg holes 112. The legs 104 may be positioned and distanced relative to each other correspond to the width or length of the pediatric medical examination table 10 to immobilize the patient support 100.
In some examples, the joint positioning device 5 may be used on a medical examination table 10 in different configurations. For example, the legs 104 of the joint positioning device in one configuration may be positioned to fit a medical examination table 10 lengthwise. The same joint positioning device 5 in another configuration may then be used to fit the medical examination table 10 widthwise, by adjusting the legs 104, without adjusting the length or dimensions of the patient support 100. For example, the legs 104 of the same joint positioning device 5 may be spaced from each other the correspond to the width of the medical examination table 10.
In some examples, a joint positioning device 5 may be used on a variety of medical examination tables 10. For example, the legs 104 of the joint positioning device 5 in one configuration may be positioned to fit a standard medical examination table 10, lengthwise or widthwise. The same joint positioning device 5 in another configuration may then be used to fit a pediatric table, widthwise or lengthwise, by adjusting the legs 104, without adjusting the length or dimensions of the patient support 100. For example, the legs 104 of the same joint positioning device 5 may be spaced from each other the correspond to the length or width of the pediatric medical examination table 10.
In some examples, the joint positioning device 5 may not include legs 104. The joint positioning device 5 may be placed on the medical examination table 10. In some examples, the joint positioning device 5 may be attached or secured to the medical examination table 10 by other means.
In some examples, one leg 104 may be attached to the patient support 100. In some examples, two legs 104 may be attached to the patient support 100, one leg 104 on the proximal end and distal end of the patient support 100.
In some examples, three legs 104 may be attached to the patient support 100, with one leg 104 on the proximal end and distal end of the patient support 100. The third leg 104 may be on either lateral end of the patient support 100. The third leg 104 may also be positioned anywhere on the patient support 100 to further stabilize or immobilize the joint positioning device 5. In some examples, the first leg 104 may be positioned on a first end of the patient support 100, the second leg 104 may be positioned on a second end of the patient support 100, and the third leg 104 may be positioned on a third end of the patient support 100. The joint positioning device 5 may be immobilized along a first axis on both sides and partially immobilized along a second axis, where the second axis is substantially perpendicular to the first axis.
In some examples, the joint positioning device 5 may include four legs 104, as shown in
The one or more legs 104 do not have to be attached to the patient support 100 before placing the patient support 100 on the medical examination table 10. For example, two legs 104 may first be positioned at a first end of the patient support 100, such as the distal end of the patient support 100. The patient support 100 may then be placed in a desired orientation, such as widthwise or lengthwise, on the medical examination table 10. Then, two other legs 104 may be adjusted and positioned at a second end of the patient support 100, such as the proximal end of the patient support 100. The second set of legs 104 may be attached to the patient support 100 at a distance from the first set of legs 104, where the distance or space between the legs 104 corresponds to the length or width of the medical examination table 10.
The legs 104 may be secured to the two ends of the patient support 100, such that they are positioned at the lateral ends or proximal and distal ends of the medical examination table 10. The legs 104 will immobilize the patient support 100, such that the joint positioning device 5 cannot be shifted in a longitudinal direction relative to the medical examination table 10.
The legs 104 may be secured to the two ends of the patient support 100, such that they are positioned at the longitudinal ends of the medical examination table 10. The legs 104 will immobilize the patient support 100, such that the joint positioning device 5 cannot be shifted in a lateral direction relative to the medical examination table 10.
In other examples, all four legs 104 may first be attached to the patient support 100, two legs 104 on the proximal and distal ends of the patient support 100. The patient positioning device 5 may then be placed on the medical examination table 10, with the two legs 104 on the lateral ends or the proximal and distal ends of the medical examination table 10.

In particular examples, the shoulder pole 500 may be positioned behind the patient. The patient may reach behind them with the arm and shoulder of interest. The patient may reach behind them towards the strap 504. In some examples, the patient may grab the strap 504 with their hand. In other examples, the patient may position and rest their hand through the strap 504 such that the patient's wrist is supported by the strap 504. The height of the shoulder pole 500 may be adjusted such that the patient can reach back to extend their arm and rotate their shoulder to reach the strap 504.
The physician may appropriately adjust the patient, strap 504, hook 502, shoulder pole 500, and/or the patient support 100 such that the patient's arm is appropriately extended and the patient's shoulder is appropriately rotated in the correct position. The physician may position or place the patient's shoulder in an outward direction to open up the glenoid cavity of the patient's shoulder. The physician may apply pressure to the shoulder such that the glenoid cavity of the shoulder becomes open. Once the patient is in the correct position, the glenoid cavity of the shoulder of interest is accessible. While the patient's shoulder and arm is being rotated or extended, the patient's upper body remains stabilized to put a slight torque or force on the patient's shoulder.
Once the glenoid cavity of the patient's shoulder is opened, the physician may then have the necessary access and visualization of the glenoid cavity of the patient's shoulder to examine the internal tissue of the shoulder, such as via a needle endoscope. The physician may insert a needle endoscope into a tissue site and collect an image. Additionally, once the glenoid cavity of the patient's shoulder is accessible, the physician may perform any necessary procedures or treatments such as an injection. The physician may then inject the patient's joint, such as via a needle endoscope, with access to the glenoid cavity of the patient's joint.
