Description

An operating table for breast puncture in lateral position

technical field

The invention relates to the field of medical beds, in particular to an operating bed for breast puncture in a lateral position.

Background technique

Gynecological chest examination usually requires multi-directional and multi-angle breast puncture, so the patient needs to change the supine position to cooperate with the examination, usually supine and lateral positions. In the supine position, the patient’s chest is fully stretched and can be fully examined, but in the lateral position, one of the patient’s arms must be below the body, and at this time the upper arm and shoulder on the lower side of the body will be Squeeze the patient's chest, so that the patient's chest cannot be fully stretched, which is not conducive to exposing the lesion, affecting the breast puncture, resulting in incomplete examination, and even endangering the patient's life and health. In the actual examination, the doctor usually asks the patient in the lateral position to put the arm under the body under the head to avoid the arm pressing the chest. Solve the problem of the chest being squeezed, and in addition, the arm pressed under the head for a long time will also cause discomfort to the patient.

In the existing medical beds used for patients in lateral position, most of them are provided with an arm support mechanism on the outside of the bed body, and the height of the arm support mechanism is approximately flush with the bed body, so that the patient can hold the The arm below the body stretches forward out of the bed and is placed on the arm support mechanism, which avoids the extrusion of the arm to the chest, but the connection between the upper arm and the shoulder is still between the bed and the body, so it will still Some squeeze on the chest, not great. In order to solve the above problems, there has been a medical bed that allows the arm to be placed under the bed body, such as a neurosurgery operating bed with a side-lying arm placement device disclosed in a Chinese patent with application number 201520844851.4, including a bed body and an arm placement device, the arm placement device includes a fixed bracket connected in sequence, an upper arm bracket and a lower arm bracket, one end of the fixed bracket is connected with the bed body, and the other end of the fixed bracket is connected with the upper arm One end of the bracket is vertically connected and the upper arm bracket is vertically arranged at the lower end of the bracket, and the other end of the upper arm bracket is vertically connected to the lower arm bracket through the shaft end. The arm placement device in this patent is located under the bed, and the upper arm bracket and the lower arm bracket are perpendicular to each other. When the patient takes a lateral position, the lower arm can be placed on the arm placement device, and the upper arm is adapted to the upper arm bracket. The lower arm is bent to adapt to the lower arm bracket, which effectively prevents the chest from being squeezed by the lower arm and realizes the stretching of the chest. However, the arm placement device in this patent is located below the edge of the bed, and the patient must place the lower arm on the arm placement device smoothly, and must be placed from the outside of the bed edge, and the patient must also lie on his side on the edge of the bed. It is very easy to roll down from the bed body, causing a safety hazard. In addition, the perpendicular shape of the upper arm bracket and the lower arm bracket in the arm placement device cannot be changed during use, which cannot meet the comfort requirements of different patients.

Detailed ways

The following specific examples are only explanations of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications without creative contribution to the present embodiment as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

In Fig. 1, a bed board 1 of an operating bed for breast puncture in the lateral position is a long board adapted to the human body. In this embodiment, the bed board 1 is set horizontally by default, and the end of the bed board 1 corresponding to the head of the human body is specified as the rear , one end corresponding to the human body's feet is the front, and the two sides of the bed board 1 are defined as the left and right sides. In addition, since the present invention is mainly used for patients who need to take a lateral position posture, the arm placement device 2 in the present invention is mainly used to place the arms below the body in the arms of a patient in a lateral position, so the arms mentioned herein are particularly Refers to the lower arm of the patient's arms in the lateral decubitus position. It is defaulted herein that in actual use there is a supporting part that lifts the bed board 1 in mid-air and there is a space for the backing board 22 to rotate downward under the arm support device 2 .

Fig. 1 shows that a kind of operating bed for breast puncture in lateral position according to the present invention includes a bed board 1 and an arm placement device 2, and the arm placement device 2 is within the overall framework of the bed board 1 instead of being directly installed on The edges of the left and right sides of the bed board 1 protrude from the bed board 1 as a whole, which saves the space resources that the medical bed needs to occupy as a whole, and also effectively reduces the damage caused by the arm placement device 2 to doctors and patients. the inconvenience. In order to enable the arm resting device 2 to be within the overall framework of the bed board 1 , in this embodiment, an accommodating groove 11 for accommodating the arm resting device 2 is provided on the left and/or right side of the bed board 1 , if it is necessary to meet the arm placement in the left or right decubitus position, then set the accommodating groove 11 on the left or right side of the bed board 1; When the arm is placed in position, the receiving groove 11 is provided on the left and right sides of the bed board 1 . The accommodating groove 11 is within the overall frame range of the bed board 1 , and the accommodating groove 11 can be reserved at a corresponding position when the bed board 1 is manufactured. Since the backing plate 22 in the arm placement device 2 occupies most of the space in the accommodating groove 11, the position of the accommodating groove 11 mainly corresponds to the position of the backing plate 22, and the pad The plate 22 is a component that directly supports the patient's arm, and it should roughly cover the range from the shoulder to the waist of the human body in the front-rear direction, so the accommodating groove 11 should also extend from the shoulder to the waist of the human body in the front-rear direction; The width of the backing plate 1 in the left-right direction is not too limited. In this embodiment, the width is preferably 1-3 times the width of the arm of a human body. Board corresponding. Of course, since the backing plate 22 needs to rotate in the up and down direction, although the shape and size of the receiving groove 11 correspond to the backing plate 22, the size of the accommodating groove 11 still needs to be slightly larger than the backing plate 22. The size is such that there is a certain gap between the backing plate 22 and the bed board 1, so as to prevent the backing plate 22 from rotating downward due to too close contact between the two. The range covered by the receiving groove 11 in the front-rear direction roughly extends from the shoulders to the waist of the human body, so when the backing plate 22 is rotated to the bottom of the bed plate 1, the arm of the patient in the side lying position has been placed on the bed sagging. On the backing plate 22, the position from the shoulder to the waist of the patient's body is located above the receiving groove 11, which is in an unsupported suspended state, and the patient's head and waist are still supported by the bed plate 1 below. Compared with the prior art where the patient needs to lie on his side on the edge of the bed board 1 in order to hang his arms from the outside of the bed board 1 to the arm support device 2, in this embodiment, the patient's arms can naturally hang down to the backing board 22 after lying on his side. without hanging down from the outside of the bed board 1, which ensures the comfort of the patient's arm placement, and also makes the patient not need to lie on the edge of the bed board 1, eliminating the hidden danger of the patient rolling down from the bed board 1, and ensuring that the patient's side Safety while lying down.

The rotating part 21 of the backing plate 22 can be installed at the front end of the receiving tank 11 along the front-back direction, or at the rear end of the receiving tank 11, that is, there are two ways for the backing plate 22 to support the patient’s arm One is that the front end of the backing plate 22 rotates downward around the rear end, and the other is that the rear end of the backing plate 22 turns down around the front end. If the first method is selected, the patient’s arm placed on the backing plate 22 fits in an oblique shape with the backing plate 22 as a whole, and the upper arm and the shoulder are close to the rotating part 21, and the upper arm fails to sag naturally. It can stretch the chest well. If the second method is selected, an angle will be opened between the backing board 22 and the bed board 1, and the distance between each position on the backing board 22 and the bed board 1 is from the rear end of the backing board 22 Decrease toward the front end, and the patient's shoulder roughly corresponds to the rear end of the backing plate 22, the patient's upper arm can hang down naturally from this position, and then the elbow joint is bent so that the lower arm is placed on the backing plate 22, in a naturally drooping state The upper arm is roughly vertical, and the patient's body is roughly horizontal under the support of the bed board 1, so that the upper arm is roughly perpendicular to the body, avoiding the extrusion of the upper arm to the chest, and the upper arm stretched out from the body further pushes the shoulder Pull the hips to the outside of the body, thereby effectively reducing the compression of the shoulders on the chest, so that the chest can be fully stretched. Therefore, in this embodiment, the above-mentioned second method is preferred, that is, the rotating part 21 is installed at the front end of the receiving groove 11 .

As a further improvement, in this embodiment, the position adjacent to the rear of the receiving groove 11 on the bed board 1 is also provided with an extending groove 12, and the extending groove 12 communicates with the receiving groove 11, and the two communicate with each other. The formed whole is L-shaped, and the protruding groove 12 roughly corresponds to the position of the patient's shoulder. In the original solution, the size of the accommodating groove 11 along the front-back direction is relatively large, and the position from the patient's shoulders to the waist cannot be supported. Applying pressure to obtain a reaction force to increase the support for the body, this puts forward higher requirements on the strength of the support structure 23 , which will inevitably increase the cost of the support structure 23 . In this embodiment, after the extension groove 12 is preferably set, the position of the patient lying on his side can be moved from above the receiving groove 11 in the original solution to above the extension groove 12 along the left and right direction, so that the patient is further away from the bed board 1 edge, further reducing the hidden danger of the patient rolling down from the bed board 1. Simultaneously, because the size of the extending groove 12 in the front-back direction is much smaller than the size of the receiving groove 11 in the front-back direction, when the patient's side lying position moves, the suspended area under the patient's body changes from the size of the receiving groove 11. By forming the protruding groove 12, the suspended area is greatly reduced. In other words, the supporting area of the patient's body by the bed board 1 is greatly improved, so that the patient can be more comfortable when lying on his side, and there is no need to apply pressure to the backing board 22 by the arms. The support to the body is increased, and the physical exertion of the patient and the strength requirements of the support structure 23 are reduced. When the patient is lying on his side on the bed board provided with the protruding groove 12, his shoulder is generally located above the protruding groove 12, and his upper arm can be stretched from the protruding groove 12 to the bottom of the bed board 1. Below, the arm is placed on the backing plate 22 with a slight inclination to the outside.

As a further improvement, the backing plate 22 also has a protruding portion 221 that can be correspondingly placed in the protruding groove 12, the shape of the protruding portion 221 is consistent with the protruding groove 12, and its size is slightly smaller than that of the protruding Out of the groove 12, there is a certain gap between itself and the bed board to prevent the close contact between the two from preventing the protruding part 221 from leaving the extending groove 12. The backing plate 22 with the protruding portion 221 is also L-shaped, and in actual use, the backing plate 22 without the protruding portion 221 can already meet the patient’s arm placement requirements, but in this embodiment The rotation of the backing plate 22 needs to be pushed manually, and the arm support device 2 also includes a support structure 23 for maintaining the position of the backing plate 22, and the support structure 23 needs to be overcome when the backing plate 22 is artificially pushed to rotate. To do work on the support of the backing plate, usually a large driving force needs to be applied, and the backing plate 22 has a simple structure, and there is no suitable stress point on it. If there is the protrusion on it, the overall shape is L-shaped , then the protruding portion 221 can act as a handle for artificially applying force to the backing plate 22, which is convenient for artificially applying force and saves the physical strength of the force-applier. In addition, when the backing plate 22 is in the receiving groove 11, the medical bed as a whole can be used as a normal medical bed for the patient. At this time, the extending groove 12 is hollow up and down, corresponding to the The parts of the body protruding from the groove 12 cannot be supported, which may cause inconvenience to the normal use of the patient and affect the appearance. The protruding part 221 can be filled in the protruding groove 12 to make up for the above deficiency.

The backing plate 22 can be rotated relative to the bed board 1 through the rotating part 21. The rotating part 21 can adopt a common hinge structure, and when the backing plate 22 is rotated to a proper position, it needs to be supported mechanism 23 to maintain the position of the backing plate 22, and the supporting force of the supporting mechanism 23 to the backing plate 22 should be able to resist the sum of the weight of the backing plate 22 itself and the pressure of the patient's arm on the backing plate 22. If the supporting force of the supporting structure 23 to the backing plate 22 is extremely large, the above requirements must be met, but considering that it may be necessary to overcome the above-mentioned supporting force to do work when the backing plate 22 is artificially pushed to rotate, the above-mentioned supporting force still needs to be completed. Satisfied that it can be overcome by a single person manually exerting force, therefore, the above-mentioned support force needs to meet two conditions at the same time, specifically analyzed according to the characteristics of the support structure. In this embodiment, the support structure 23 is preferably the first damping shaft 24 installed in the rotating part 21. When the bed board 1 adopts the scheme with the protruding groove 12, the bed board 1 has a positive impact on the patient's body. To get good support, the patient just puts his arm on the backing board 22, and does not need to apply force to the backing board 22 in normal use, so the supporting force required by the backing board 22 is small, and the second The resistance generated by a damping rotating shaft 24 to the rotating part 21 is enough to keep the backing plate 22 in a certain position without rotation, and the resistance is enough to be easily disengaged when a single person applies force to the backing plate 22. overcome. Adopting the scheme of the first damping rotating shaft 24 also makes the use of the arm placement device 2 extremely convenient, as long as the user applies force to the backing plate 22, the rear end can be pushed down to any desired position. In use, it is mainly satisfied that the rear end can rotate within the range of 0-90° downward. The second embodiment of the support structure 23 includes a support element 231 with one end rotatably mounted on the inward side of the backing plate 22 and several front and rear support elements arranged on the side of the bed board 1 facing the backing plate 22 . Arranged fixed columns 232, the other end of the support element 231 is provided with a positioning sleeve 233 that can pass through the fixed column 232, the front end of the support element 231 is rotatably mounted with the backing plate 22 and the rear end has the Positioning sleeve 233. When the backing plate 22 is in the initial position, the front end and the rear end of the support element 231 are kept horizontal, and the positioning sleeve 233 is matched with the positioning column 232 at the rearmost end, and one end of the support element 231 is pulled to the The other end of the fixed column 232 at the rear end pulls the hinge between itself and the backing plate 22, thereby maintaining the level of the backing plate 22; The positioning sleeve 233 is separated from the fixing column 232, and after the backing plate 22 is rotated to a certain position, the positioning sleeve 233 on the supporting element 231 is matched with the positioning column 232 at the corresponding position. This supporting structure is relatively Stable, as long as the strength of the material is sufficient, it can effectively prevent the backing plate 22 from continuing to rotate downwards, but it is cumbersome to manually adjust the position of the support element 231 during use. Combining the above two implementations, a third implementation of the support structure 23 can be designed, that is, the cooperation between the positioning sleeve 233 and the fixing column 232 in the second implementation is changed to the cooperation between the slider and the slide rail. The slide rail is arranged at the position where the fixed columns 232 are arranged in the original solution, and the slider is arranged at the position of the positioning sleeve 233 in the original solution, and there is a rotation between the slider and the support element 231 connected, the whole of the slider is arranged on the slide rail, and there is a sliding connection with damping between the slider and the slide rail. When the backing plate 22 rotates downward, it will drive the end of the supporting element 231 connected to it to move downward, and then generate a force of pulling forward on the other end of the supporting element 231, the supporting element 231 The other end realizes the position change through the movement of the slider in the slide rail, and the damping between the slider and the slide rail can maintain the position relationship.

When the patient is using the medical bed normally, his arm is placed on the backing plate 22, and the arm should not exert force as far as possible, mainly relying on the bed plate 1 to support the patient's body. When the bed board 1 did not have the stretching groove 12, the patient's body was suspended from the shoulders to the waist while the head, neck and waist were supported by the bed board 1; when the bed board 1 had the stretching groove 12, the patient The shoulders of the body are suspended in the air while the head and neck and the shoulders are supported by the bed board 1 below. In the above two cases, the patient's head and neck will be subject to a greater support force, especially in the first case above, the pressure on the patient's head and neck is relatively high, which will cause discomfort to the patient, so it is necessary to provide good support for it. It's in good shape. In this embodiment, a headrest device 3 specially used to support the patient's head and neck is preferably provided on the rear side of the bed board 1, including a pillow 31 and a height adjustment mechanism 32 for adjusting the height of the pillow 31. In actual use The pillow 31 can be adjusted to the required height to meet the requirements of patients of different sizes. Usually, in order to keep the head and neck in a good posture to bear the pressure and keep the neck level, the pillow 31 can be adjusted to a height where the head can be supported so that the neck is level. In this embodiment shown in FIG. 4 , it is preferred that the height adjustment mechanism 32 includes two substantially parallel support plates 321 , one end of the support plate 321 is rotatably connected to the rear side of the backing plate 22 and the other end is rotatably connected to the pillow 31 The adjustment of the height of the pillow 31 can be realized by rotating the support plate 321; the two support plates 321 are provided with mounting holes 322 at corresponding positions in the up and down direction, and one of the mounting holes 322 is put into a belt There is a nut 324 with a pressing piece 323, the pressing piece 323 is in close contact with the support plate 321, and a bolt 325 matched with the nut 324 is inserted in the other mounting hole 322, and the bolt 325 is connected to the nut 324. When the nut 324 is tightened, the head of the bolt 325 is close to one of the support plates 321, and the pressing piece 323 of the nut 324 is close to the other support plate 321. The support plate 321 is locked to fix its position.

When the left and right sides of the medical bed are provided with the arm supporting device 2, the patient can take the left or right lying position as required, but in this case the width of the bed board 1 is often larger, and the It is required that the width of the pillow 31 can also adapt to the width of the bed board 1. In order to save costs, the headrest device 3 in this embodiment preferably further includes a moving mechanism 33 for driving the pillow 31 to move in the left and right directions. A smaller pillow is sufficient. When the patient is lying on the left side, the pillow 31 is moved to the left area; when the patient is lying on the right side, the pillow 31 is moved to the right area, which effectively saves the cost of the pillow 31 . In this embodiment, the moving mechanism 33 preferably includes a support 331 and at least two slide bars 334 fixed below the pillow 31. The two slide bars 334 are parallel to each other and extend along the left and right directions. The support 331 There are support plates 332 on the left and right sides, and the support plate 332 is provided with a limit hole 333 for the slide bar 334 to pass through. The pillow 31 is erected on the support plate 332 through the slide bar 334 and can Move in the limit hole 333 in the left and right directions. After the moving mechanism 33 is added, the height adjustment mechanism 32 is directly connected in rotation with the pillow 31 in the original solution, and becomes indirectly connected in rotation with the pillow 31 through the rotation connection with the support 331 .
