Description

Technical Field

[0001] The present invention relates to a medical mechanical fixing and protection technology, and in particular to a novel surgical posture safety protection device, specifically a safety protection device used in laparoscopic breast cancer surgery. Background Art

[0002] Breast cancer has become the first in the incidence of malignant tumors in women in my country and the fifth in the mortality rate of malignant tumors. Its incidence rate has been increasing year by year with the development of urbanization. The screening and treatment of breast cancer have been increasingly valued by domestic and even global scholars. Clinically, laparoscopic surgery for breast cancer is used to treat breast cancer. In order to effectively cooperate with laparoscopic surgery for breast cancer, it is urgently necessary to find a safe and comfortable surgical position and develop new safety protection equipment to help patients pass the operation smoothly.

[0003] At present, laparoscopic breast cancer surgery uses traditional body positioning devices such as "L"-shaped anesthesia head frame and pelvic fixation frame. The existing laparoscopic breast cancer surgery body positioning has the following shortcomings:

[0004] 1. In order to relax the pectoralis major muscle and clearly expose the surgical field of view, the affected upper limb is often wrapped with a cotton pad and the bandage is fixed on the "L"-shaped anesthesia head frame. During the bandage process, due to the surgeon's tight bandage and the upper limb being in elbow flexion for a long time, skin redness and swelling, upper limb swelling and venous return obstruction are prone to occur after the operation, which may cause nerve damage, leading to numbness of the upper limb and decreased finger flexibility.

[0005] 2. The use of square positioning pads and pelvic fixation frames may cause the waist to be suspended in the air and the chest to be compressed. The trunk is prone to slide down and shift during the operation, causing the trunk to be in a twisted state for a long time, leading to lumbar muscle strain. Patients often complain of low back pain after surgery.

[0006] 3. The placement of the patient in the surgical position often requires the cooperation of 4-5 people at the same time, which wastes manpower, prolongs the patient's anesthesia time, and is not conducive to their rapid recovery. Summary of the invention

[0007] In order to overcome the shortcomings of the prior art, the present invention combines the existing surgical position placement mode, safe surgical position placement principles and anatomy, human mechanics and engineering, and explores the improvement of laparoscopic breast cancer surgery position placement, with the aim of providing a "moon-gazing" position safety protection device for laparoscopic breast cancer surgery.

[0008] The purpose of the present invention is achieved by adopting the following technical scheme: a safety protection device used in laparoscopic breast cancer surgery, comprising a sloped position pad for raising the affected side of the patient, a healthy side fixing pad for preventing the patient from shifting to the healthy side, and an improved armrest for exposing the position of the affected side armpit of the patient;

[0009] The slope body position pad is provided with a first inclined surface; the healthy side fixing pad is provided with a second inclined surface; the healthy side fixing pad is connected to the slope body position pad via a connecting belt;

[0010] The improved hand support frame includes a fixing frame fixed on the operating bed and a hand support gasket installed on the fixing frame; the hand support gasket includes a horizontal pad portion and a flexure pad portion; the flexure pad portion is bent downward from one end of the horizontal pad portion, and a transition bending portion is provided between the horizontal pad portion and the flexure pad portion, and the angle between the horizontal pad portion and the flexure pad portion is 100-160°.

[0011] Furthermore, the slope positioning pad is provided with a first inclined surface with an arc, the first inclined surface with an arc is consistent with the physiological curvature of the back of the human trunk, and the angle between the first inclined surface and the horizontal plane is 15-30°; the healthy side fixing pad is provided with a second inclined surface with an arc, the second inclined surface with an arc is consistent with the physiological curvature of the thorax of the human trunk, and the angle between the second inclined surface and the horizontal plane is 150-165°.

[0012] Furthermore, the height of the healthy side fixing pad is less than 1 / 2 of the width of the human body trunk; the length of the healthy side fixing pad is the length from the human body's armpit to 5-10 cm below the anterior superior iliac spine.

[0013] Furthermore, the length of the slope body positioning cushion is the length from the acromion to the ischial tuberosity of the human body; the width of the first inclined surface of the slope body positioning cushion is greater than 1 / 2 of the width of the human trunk; the height of the slope body positioning cushion is sinα×the width of the first inclined surface, wherein α is the angle between the first inclined surface and the horizontal plane.

[0014] Furthermore, the slope body positioning cushion and healthy side fixing cushion are inflatable body positioning cushions.

[0015] Furthermore, a hard base is provided at the bottom of the sloped body positioning pad and the healthy side fixing pad.

[0016] Furthermore, the connecting belt is provided with an adjustable structure to achieve that the width between the sloped position pad and the healthy side fixing pad can be adjusted according to the patient's body shape.

[0017] Furthermore, the adjustable structure is Velcro, which includes a bristle veneer with hooks and a round hair veneer; the bristle veneer with hooks is fixed to the bottom of the healthy side fixing pad, and the round hair veneer is fixed to the connecting belt.

[0018] Furthermore, the height of the fixing frame of the improved hand support frame is adjustable, and / or the length of the hand support gasket of the improved hand support frame is adjustable.

[0019] Furthermore, the improved hand support frame also includes a sleeve; the sleeve includes a forearm sleeve, an elbow sleeve, and an upper arm sleeve that are connected in sequence; the sleeve is provided with a plurality of fixing straps for fixing the patient's upper limbs on the hand support pad.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) Compared with the body positioning equipment in the prior art, the safety protection equipment of the present invention has a larger contact surface with the patient's body, which reduces the abnormal pressure on the various points of force of the body after the body position changes, and reduces the risk of damaging the skin, nerves, and muscles; the width and length of the body positioning pad can be tailored according to the actual situation of the patient, which is more suitable for the patient's physiological structure; the body positioning pad is made of soft and breathable materials to increase the patient's comfort; the healthy side fixing pad fixes the patient's hip to avoid compression of the healthy side chest and reduce the impact on respiratory circulation. It makes the body positioning operation of medical personnel more labor-saving and convenient, greatly reduces the time and number of people required for surgical position placement, and speeds up the surgical process.

[0022] (2) The present invention designs an arc-shaped inclined surface on the sloped positioning pad and the healthy side fixing pad that is consistent with the physiological curvature of the human trunk back and thorax, so that the contact surface between the positioning pad and the patient's body is larger, limiting the range of position change during surgery, reducing the abnormal pressure on various fulcrums of the body after the position changes, and reducing the risk of damaging the skin, nerves, and muscles.

[0023] (3) The height, width and length of the slope position pad are cleverly designed. The width of the slope position pad is more important. If the width of the slope position pad is too narrow, the patient's affected side will be suspended for a long time (the patient adopts the "moon-gazing" supine position for surgery, and the laparoscopic breast cancer surgery time is about 3 hours), causing the trunk to twist. Long-term compression can increase the risk of compression injury, leading to lumbar muscle injury, low back pain in patients after surgery, and serious complications. If the width of the slope position pad is too wide, it will be inconvenient for the surgeon to perform the surgery and cause visual impairment. Therefore, it is preferred that the width of the first inclined surface of the slope position pad is greater than 1 / 2 of the width of the human trunk and less than the width of the human trunk. In addition, the height of the slope position pad can be calculated according to the width of the slope position pad and the angle between the first inclined surface and the horizontal plane to obtain a reasonable height, which is more suitable for the patient's physiological structure, and the length of the slope position pad is also tailored according to the actual situation of the patient, which is more suitable for the patient's physiological structure.

[0024] (4) The height and length of the healthy side fixation pad are cleverly designed. The height of the healthy side fixation pad is designed to avoid compression of the healthy side chest and reduce the impact on respiratory circulation. The starting point of the healthy side fixation pad is set at the armpit of the human body, so that the healthy side upper limb can be freely placed on the operating table without compression, and the respiratory circulation is smoother. In addition, the lateral fixing point of the healthy side fixation pad is mainly the anterior superior iliac spine, which basically fixes the patient's upper body, reduces the patient's activity space, and makes the operation more smoothly.

[0025] (5) The design of the hard base at the bottom of the positioning cushion can increase the friction between the sloped positioning cushion, the healthy side fixation pad and the operating table, thereby reducing the displacement of the body position during surgery.

[0026] (6) The design of adjustable width of the connecting belt is suitable for patients of different body shapes, which ultimately increases the contact area between the slope position pad, the healthy side fixation pad and the patient's body, reduces the abnormal pressure of each force point of the body, and reduces the risk of damaging the skin, nerves and muscles. Velcro is preferably used to adjust the width of the connecting belt. This adjustment method is convenient, fast and low-cost; and the round wool veneer is a flexible surface, so the human body will not feel a foreign body when lying on the connecting belt, which improves the patient's comfort during the operation.

[0027] (7) The sleeve and the improved hand support are more suitable for the patient's physiological structure. The design of the sleeve and the curved shape of the hand support pad matches the patient's physical condition, physiological function and comfort. On the one hand, the contact surface with the patient's body is larger, which reduces the abnormal pressure on the body's various points of force after the body position changes, and reduces the risk of damaging the skin, nerves and muscles; on the other hand, the sleeve and the hand support pad are made of soft and breathable materials, which increases the patient's comfort. In addition, the height-adjustable design of the fixed frame of the improved hand support can adjust the height of the hand support pad according to the length of the affected upper limb and the exposure of the axillary, thereby improving the patient's comfort during and after surgery.

DETAILED DESCRIPTION

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] This application obtains specific data for the design of safety protection equipment by measuring population data, and obtains its final design drawing in combination with the preliminary design drawing of the safety protection equipment, so that it conforms to anatomy, human mechanics and engineering, and is manufactured. The manufactured safety protection equipment is applied to the clinical practice of laparoscopic breast cancer surgery, proving its safety and practicality, and can achieve the purpose of reducing the related complications caused by poor surgical positioning of patients.

[0041] like Figure 1-10 As shown, a safety protection device used in laparoscopic breast cancer surgery includes a sloped position pad 1 for raising the affected side of the patient, a healthy side fixing pad 2 for preventing the patient from shifting to the healthy side, and an improved armrest 3 for exposing the affected side armpit position of the patient;

[0042] The slope body position pad is provided with a first inclined surface 11; the healthy side fixing pad is provided with a second inclined surface 21; the healthy side fixing pad is connected to the slope body position pad via a connecting belt 4;

[0043] The improved hand support frame includes a fixing frame 31 fixed on the operating bed and a hand support gasket 32 ​​installed on the fixing frame; the hand support gasket includes a horizontal pad portion 321 and a flexion pad portion 322; the flexion pad portion is bent downward from one end of the horizontal pad portion to conform to the natural bending shape of the human upper limb, and a transition bending portion 323 is provided between the horizontal pad portion and the flexion pad portion, and the angle θ between the horizontal pad portion and the flexion pad portion is 100-160°.

[0044] As a further preferred solution, Figure 4-7 As shown, the schematic diagram of the structure of the slope position pad and the healthy side fixing pad is as follows: the slope position pad is provided with a first inclined surface 11-1 with an arc, the first inclined surface with an arc is consistent with the physiological curvature of the back of the human trunk, and the angle α between the first inclined surface and the horizontal plane is 15-30°; the healthy side fixing pad is provided with a second inclined surface 21-1 with an arc, the second inclined surface with an arc is consistent with the physiological curvature of the thorax of the human trunk, and the angle β between the second inclined surface and the horizontal plane is 150-165°. The slope position pad and the healthy side fixing pad are designed with an inclined surface with an arc that is consistent with the physiological curvature of the back of the human trunk and the thorax, so that the contact surface between the position pad and the patient's body is larger, the range of position changes during surgery is limited, the abnormal pressure on each force point of the body after the position changes is reduced, and the risk of damaging the skin, nerves, and muscles is reduced.

[0045] As a further preferred solution, the height of the healthy side fixing pad is less than 1 / 2 of the human body trunk width, preferably about 10-15cm; the length of the healthy side fixing pad is 5-10cm below the anterior superior iliac spine from the human body armpit, preferably about 35-50cm. The height design of the healthy side fixing pad avoids compression of the healthy side chest and reduces the impact of respiratory circulation; the starting point of the length of the healthy side fixing pad is set at the human body armpit, so that the healthy side upper limb can be freely placed on the operating table without compression, and the respiratory circulation is smoother. In addition, the lateral fixing point of the healthy side fixing pad is mainly the anterior superior iliac spine, which basically fixes the patient's upper body, reduces the patient's activity space, and makes the operation more smoothly.

[0046] As a further preferred solution, the length of the slope position pad is the length from the acromion to the ischial tuberosity of the human body, preferably the length of the slope position pad is about 35-60cm, and preferably one slope position pad is provided for every 5cm increase in length to improve the applicable scope of each pad; the width of the first inclined surface of the slope position pad is greater than 1 / 2 of the width of the human trunk, preferably the width of the first inclined surface is about 25-55cm; the height of the slope position pad is sinα×the width of the first inclined surface, wherein α is the angle between the first inclined surface and the horizontal plane. For example, the width of the first inclined surface is 30cm, the angle α between the first inclined surface and the horizontal plane is 30°, and the height of the slope position pad = sin30×30cm = 0.5×30cm = 15cm. Preferably, the height of the slope position pad is about 4-15cm. The width of the slope position pad is relatively important. If the width of the slope position pad is too narrow, the patient's affected side will be suspended for a long time (the patient adopts the "moon-gazing" supine position for surgery, and the laparoscopic breast cancer surgery time is about 3 hours), causing the trunk to twist. Long-term compression can increase the risk of compressive injury, leading to lumbar muscle injury, low back pain in patients after surgery, and serious complications. The width of the slope position pad is too wide, which is not conducive to the surgeon performing the operation and causes visual impairment. Therefore, it is preferred that the width of the first inclined surface of the slope position pad is greater than 1 / 2 of the width of the human trunk and less than the width of the human trunk. In addition, the height of the slope position pad can be calculated according to the angle between the width of the slope position pad and the first inclined surface and the horizontal plane to obtain a reasonable height, which is more suitable for the patient's physiological structure, and the length of the slope position pad is also tailored according to the actual situation of the patient, which is more suitable for the patient's physiological structure.

[0047] As a further preferred solution, the slope body position cushion and the healthy side fixing cushion are inflatable body position cushions. That is, the slope body position cushion and the healthy side fixing cushion are connected to an external inflatable device to achieve inflation and deflation, and the specific external inflatable device includes an air pump for inflation, a solenoid valve assembly for adjusting the air volume at the air output end of the air pump, and a controller for controlling the operation of the air pump and the solenoid valve assembly.

[0048] The inflation principle of the positioning cushion is as follows: when the controller sends an inflation signal, the controller controls the air pump and the solenoid valve to inflate the slope positioning cushion and the healthy side fixing cushion through the air intake pipe, and the solenoid valve is used to adjust the inflation volume; when the controller sends a deflation signal, the controller controls the air pump and the solenoid valve to deflate the slope positioning cushion and the healthy side fixing cushion through the air intake pipe, and the solenoid valve is used to adjust the deflation volume.

[0049] As a further preferred solution, a hard base is provided at the bottom of the slope position pad and the healthy side fixing pad. The design of the hard base can increase the friction between the slope position pad, the healthy side fixing pad and the operating table, and reduce the displacement of the body position during the operation.

[0050] As a further preferred solution, the connecting belt is provided with an adjustable structure to achieve the width between the slope position pad and the healthy side fixing pad being adjustable according to the patient's body shape. The design of the adjustable width of the connecting belt is suitable for patients of different body shapes, and ultimately makes the contact surface between the slope position pad, the healthy side fixing pad and the patient's body larger, reducing the abnormal pressure on each force point of the body after the body position changes, and reducing the risk of damaging the skin, nerves and muscles.

[0051] As a further preferred solution, the adjustable structure can be a structure for adjusting the length of the connecting belt in the prior art, such as a buckle structure, Velcro, etc. The present invention preferably uses Velcro to adjust the length of the connecting belt, and the Velcro includes a hooked bristle veneer and a round bristle veneer; the hooked bristle veneer is fixed to the bottom of the healthy side fixing pad, and the round bristle veneer is fixed to the connecting belt. The Velcro is convenient, fast, and low-cost to adjust; and the round bristle veneer is a flexible surface, so the human body will not feel a foreign body when lying on the connecting belt, thereby improving the comfort of the patient during surgery.

[0052] As a further preferred solution, the height of the fixing frame of the improved hand support is adjustable, and the preferred fixing frame height is about 25-40 cm. The fixing frame includes an upper fixing rod 311 and a lower fixing rod 312, and the upper fixing rod is inserted or sleeved on the lower fixing rod through existing fasteners 313 such as screws. The improved hand support is installed on the surgical side of the operating table according to the position of the affected armpit, and the height of the hand support pad is adjusted according to the length of the affected upper limb and the exposure of the armpit. In addition, the outer surface of the fixing frame is coated with insulating material to prevent the patient's head or other parts from directly contacting the metal and avoiding electric burns.

[0053] As a further preferred solution, the length of the hand support pad of the improved hand support frame is adjustable, and the preferred length of the hand support pad is about 20-30 cm. The hand support pad preferably adopts a sleeve-type telescopic structure to achieve length adjustment. The sleeve-type telescopic structure can be specifically formed by sleeves of different diameters being sleeved in sequence to adapt to the length of different patients' upper limbs, especially the length of the upper forearm.

[0054] As a further preferred embodiment, the improved hand support frame further includes a sleeve 5. The sleeve includes a forearm sleeve 51, an elbow sleeve 52, and an upper arm sleeve 53 which are connected in sequence; the sleeve is provided with a plurality of fixing straps 54 for fixing the patient's upper limbs on the hand support pad. In addition, the elbow sleeve is provided with pleats extending along the circumference of the elbow sleeve at a position corresponding to the elbow, which can facilitate the bending movement of the elbow. The elbow sleeve serves as the natural bending portion of the forearm sleeve and the upper arm sleeve. The upper arm sleeve is bent downward from one end of the forearm sleeve to conform to the natural bending shape of the human upper limb. The angle θ between the forearm sleeve and the upper arm sleeve is 100-160°, which matches the bending shape of the hand support pad to fully consider the patient's physical condition, physiological function and comfort. The use of the sleeve and the improved hand support, on the one hand, increases the contact surface with the patient's body, reduces the abnormal pressure on various points of force of the body after the body position changes, and reduces the risk of damaging the skin, nerves and muscles; on the other hand, the sleeve and the hand support pad are made of soft and breathable materials, which increases the comfort of the patient.

[0055] In the present invention, before making the sizes of the slope position pad and the healthy side fixing pad, the arm length and diameter, trunk length and curvature data of the crowd are collected, the size specifications of the safety protection equipment for laparoscopic breast cancer surgery are designed and made, 100 adult females are selected, grouped by height and weight, the length and diameter of the upper limbs, the length and curvature of the trunk are measured, different specifications are formulated according to the patient's body shape, and safety protection equipment of different sizes and specifications are prepared to maximize the range of intraoperative position changes.

[0056] The method of using the safety protection device of the present invention in laparoscopic breast cancer surgery is as follows:

[0057] (1) Choose a sloped positioning cushion according to the patient's body shape and raise the patient's affected side approximately 15°-30°.

[0058] (2) Install the modified armrest on the surgical side of the operating table according to the position of the patient's affected axilla, and adjust the height of the armrest according to the length of the affected upper limb and the exposure of the axilla.

[0059] (3) The patient's affected upper limb is protected with a sleeve and fixed to the improved arm support with a strap.

[0060] (4) Select a healthy side fixation pad according to the patient's body shape to fix the patient's healthy side hip.

[0061] The control group used conventional body position fixtures with existing technology. The square body position pad was placed under the trunk. The patient's body position was adjusted so that the lateral chest wall and the edge of the bed were at the same level. The pelvic fixation frame was fixed to the waist on the healthy side. The cotton pad was wrapped around the affected upper limb, and the upper limb was fixed to the anesthesia head frame with a bandage.

[0062] After the operation, check the effectiveness of the two protective devices, observe whether the body position has changed, whether the safety protective devices have slipped, and the skin integrity.

[0063] Specific observation indicators include: preoperative assessment of shoulder joint range of motion, upper limb movement and sensation; immediate postoperative observation of the skin integrity, swelling degree, upper limb venous return, and degree of body position change of the affected upper limb; and 72 hours after surgery, the swelling degree, nerve damage, and muscle damage of the affected upper limb.

[0064] Compared with the body positioning tools in the prior art, the improved body positioning pad of the present invention has a larger contact surface with the patient's body, which reduces the abnormal pressure on the various points of force of the body after the body position changes, and reduces the risk of damaging the skin, nerves, and muscles; the width and length of the body positioning pad can be tailored according to the actual situation of the patient, which is more suitable for the patient's physiological structure; the body positioning pad is made of soft and breathable materials to increase the patient's comfort; the healthy side fixing pad fixes the patient's hip to avoid compression of the healthy side chest and reduce the impact on respiratory circulation. It makes the body positioning operation of medical staff more labor-saving and convenient, greatly reduces the time and number of people required for surgical position placement, and speeds up the surgical process.

[0065] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
