Description

Technical Field

[0001] This invention relates to the field of medical surgical aids technology. Background Technology

[0002] Breast surgery is a common treatment for breast diseases, especially in the diagnosis and treatment of breast cancer, where its importance is self-evident. With advancements in medical technology and increasing surgical demands, breast surgery techniques and equipment are constantly being updated and improved. Traction devices used in breast surgery are crucial auxiliary equipment during the procedure, significantly impacting both the outcome and safety of the surgery.

[0003] Breast surgery mainly includes breast lump removal, radical mastectomy, and breast reconstruction. The surgical procedure typically involves delicate manipulation of breast tissue and precise tumor removal. Traction devices are needed to assist surgeons in exposing the surgical field and stabilizing breast tissue, preventing tissue retraction or displacement, thereby improving surgical precision and safety. Simultaneously, the size of the surgical field needs to be adjusted in real time according to the surgeon's needs to help prevent bleeding problems caused by prolonged traction on body tissue.

[0004] Traditional traction devices for breast surgery are mostly manual traction devices or simple mechanical traction devices, which have limitations such as unstable fixation, limited field of vision, and inability to adjust the size of the surgical field in a timely manner to cooperate with the doctor's operation.

[0005] Accordingly, existing technologies also provide traction devices capable of stable fixation. For example, Chinese patent CN106725648B discloses a multi-directional suction breast fixation device for minimally invasive breast surgery, along with its installation and usage methods. This multi-directional suction breast fixation device for minimally invasive breast surgery includes two symmetrically arranged bases, each with a worktable. A rotating shaft hole is provided on each worktable, and a gantry frame is positioned between the two worktables. The legs of the gantry frame are axially connected to the rotating shaft holes. A traction part for traction and fixation of the breast is slidably arranged on the crossbeam of the gantry frame. The angle of the breast is adjusted by fixing the relative rotation angle between the gantry frame and the worktable. A method for using a multi-directional suction breast fixation device for minimally invasive breast surgery is also disclosed. The method includes: 1-1) adjusting the height of the gantry beam according to the needs of the surgery, and adjusting the connection length of the working rod and the adjusting link through the adjusting holes and bolts; 1-2) using the base, the worktable and the gantry to set the traction unit above the patient's surgical site, and then using the traction unit to fix the breast to be operated on. When it is necessary to adjust the breast exposure angle, the gantry is driven to rotate along the axis of rotation and / or the position of the traction unit is adjusted left and right along the beam and then fixed.

[0006] Another Chinese patent, CN 221450675U, discloses a retraction device for breast surgery. The device includes surgical field retraction scissors, a toothed handle, a spring-loaded handle, and a depth tissue baffle. The surgical field retraction scissors are connected to the toothed handle and the spring-loaded handle, respectively. The depth tissue baffle is disposed at the openings on both wings of the surgical field retraction scissors.

[0007] However, existing technologies still have shortcomings. The aforementioned retraction devices require manual control by medical staff, which can easily lead to secondary damage to body tissues due to staff fatigue during prolonged surgeries. Prolonged stretching of the surgical incision can also cause blood vessels around the incision to rupture due to prolonged tension, resulting in unexpected bleeding. Therefore, there is an urgent need to develop a traction device that can adjust the size of the surgical field according to the needs of medical staff, thereby reducing damage to body tissues. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a traction device and method for reducing bodily damage during breast surgery. The traction device provided by this invention identifies and predicts the required procedures for the incision by setting an incision operation requirement recognition component. Accordingly, the traction component performs appropriate operations, adjusting the size of the surgical field according to the surgical needs, effectively reducing damage to bodily tissues and minimizing manual adjustments to the traction device by medical personnel.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a breast surgery traction device for reducing bodily damage, comprising a support, a traction arm, a traction assembly, and a control assembly. The support includes a U-shaped support arm, a secondary support arm, and a base. The traction assembly includes one or more traction plate groups, each including an upper traction plate and a lower traction plate. It also includes an incision operation requirement recognition component for identifying the operation requirements of the incision. The control assembly acquires the result identified by the incision operation requirement recognition component and controls the traction assembly to adjust the opening degree of the aforementioned incision accordingly based on the result.

[0010] Furthermore, a suction cup is provided on the lower surface of the upper traction plate, an air passage is provided inside the traction arm, and the interior of the upper traction plate is connected to an air pump through the air passage.

[0011] Furthermore, a support frame is provided inside the lower traction plate; a pressure sensor is provided on the upper surface of the lower traction plate, which can acquire the pressure data of the tissue.

[0012] Furthermore, the support frame inside the lower traction plate is fan-shaped or arc-shaped.

[0013] Furthermore, an airbag is provided on the lower surface of the lower traction plate to compress the bleeding site.

[0014] Furthermore, the incision operation requirement identification component includes an information acquisition device, an information processing device, and a dynamic damage early warning component. The information acquisition device includes an image acquisition module and a personal information acquisition module. The image acquisition module is used to acquire image information of the incision and its vicinity. The personal information acquisition module is used to acquire the patient's personal information. The information processing device is used to process the aforementioned information and transmit the processing results to the dynamic damage early warning component. The dynamic damage early warning component is used to calculate the probability of tissue damage risk based on the obtained processing results.

[0015] Furthermore, the incision operation requirement recognition component is configured to perform the following steps:

[0016] S01. Collect patient information through an information collection device;

[0017] S02. Set the threshold of the cut operation requirement recognition module according to the aforementioned information;

[0018] S03. Use the traction assembly to fix the position of the body tissues;

[0019] S04. Collect information on incision operation requirements and determine the incision operation requirements;

[0020] S05. The control component controls the traction component to change the opening degree of the cut according to the requirements of the cutting operation.

[0021] Furthermore, the threshold includes one or more of the following: time threshold, displacement threshold, bleeding threshold, and tension threshold.

[0022] Furthermore, the time threshold is the maximum time that the offset state can be maintained; the displacement threshold is a certain distance that the surgical instruments held by the doctor move away from / approach the aforementioned incision; the bleeding threshold is a certain percentage of the area occupied by blood in the surgical field; and the tension threshold is the amount of tension that the tissue can withstand with minimal damage.

[0023] Furthermore, the threshold in step S02 is modified based on the information obtained by the surgical demand identification component.

[0024] Compared with existing technologies, this invention, by employing the above technical solutions, has the following advantages and positive effects: The breast surgery traction device provided by this invention, which reduces bodily damage, utilizes a recognition component to provide real-time feedback on the condition of the surgical field, enabling adjustments to the incision opening degree according to the operational needs of the incision, thus reducing the patient's bleeding risk and improving the safety of the surgery. Furthermore, the inclusion of an information acquisition and processing device allows for personalized customization for each patient, enhancing their experience. Attached Figure Description

[0040] Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] Explanation of technical terms:

[0042] surgery field "Surgical field" is a medical term referring to the area of ​​vision within the surgical field. Before surgery, the surgeon typically disinfects the surgical area and covers areas not directly accessible with sterile drapes, exposing only the areas that need to be exposed. This exposed area is called the surgical field before surgery begins. As the surgery progresses, the surgical field changes. In endoscopic surgery, the endoscopic field of view is the surgical field. In this application, the surgical field is similar to the concepts of visual field and illumination field, all referring to the area that the surgeon can see during surgery.

[0043] Incision: refers to the cut made during surgery. In medicine, it is also called a "surgical incision".

[0044] Expansion degree: refers to the extent to which the incision is stretched open. Example

[0045] See Figure 1 The figure shows a schematic diagram of a breast surgery traction device for reducing bodily damage provided by the present invention. Referring to the figure, the breast surgery traction device 100 for reducing bodily damage includes a support 110, a traction arm 130, a traction assembly 200, and a control assembly 300. The support 110 includes a base 111 and a U-shaped support arm 120. A secondary support arm 121 for inserting the U-shaped support arm is disposed above the base. A fixing member 122 for fixing the height of the U-shaped support arm 120 is disposed on the secondary support arm 121.

[0046] The crossbeam portion of the U-shaped support arm 120 is provided with one or more traction arms 130. In this embodiment, two independent traction arms are provided. A traction assembly 200 is connected to the end of the traction arm 130. The traction arm 130 is connected to the crossbeam portion of the U-shaped support arm 120 via a movable slide 132. A traction arm position adjustment knob 131 is provided on the outer side of the end of the crossbeam of the U-shaped support arm 120. This knob is used to control the position movement of the traction arm 130 in the crossbeam portion. The traction arm 130 drives the traction assembly 200 to move laterally along the U-shaped support arm 120, thereby controlling the traction assembly 200 to open and close the cut.

[0047] Preferably, the position of the traction arm 130 is adjusted electrically. By way of example and not limitation, a servo motor, an electric slide, or the like can be used to adjust the position of the traction arm.

[0048] By way of example and not limitation, the base is a clamping structure that is fixed to the operating table by bolts. The base can also be placed on the ground.

[0049] In practical use, the base of the traction device is fixed to the operating table, the two arms of the U-shaped support arm are inserted into the secondary support arms on both sides, the height of the U-shaped support arm is adjusted according to the patient's actual needs, and it is fixed by the fastener 122.

[0050] See Figure 2 The diagram shows another structural schematic of a breast surgery traction device for reducing bodily damage provided by the present invention. The first traction arm 134 and the second traction arm 135 intersect at the support shaft 133 at their midpoints. The upper ends of the two traction arms are slidably fixed to the aforementioned crossbeam portion, and the lower ends of the two traction arms 130 are respectively connected to their respective traction components 200. Using a scissor-like working principle, the distance between the traction components is changed accordingly to alter the incision opening.

[0051] See Figure 3The diagram shows the internal structure of the U-shaped support arm provided in an embodiment of the present invention. Various mechanical structures can be used to control the movement of the traction arm. As an example, and not a limitation, this embodiment uses a screw and gear mechanism. When the traction arm position adjustment knob 131 controls the screw 123 to rotate clockwise, the first gear 124 and the second gear 125 move towards each other; when the screw 123 rotates counterclockwise, the first gear 124 and the second gear 125 move in opposite directions. Correspondingly, combined with... Figure 2 As shown, the first gear 124 drives the first traction arm 134 to move, and the second gear 125 drives the second traction arm 135 to move.

[0052] As an example rather than a limitation, the traction arm can be operated using a small robotic arm.

[0053] See Figure 4 The diagram shows a structural schematic of a traction assembly provided in an embodiment of the present invention. A traction plate assembly is provided at the lower end of the traction arm 130. The lower traction plate 210 is connected to the bottom end of the traction arm 130; a sliding traction arm 223 is sleeved on the traction arm 130, and an upper traction plate 220 is fixed to the sliding traction arm 223. The upper traction plate 220 and the lower traction plate 210 face each other, and together they fix the tissue around the incision.

[0054] By way of example and not limitation, a support frame 213 is provided inside the traction arm, and the support frame extends into the interior of the lower traction plate 210. Preferably, the lower traction plate 210 has a certain thickness, which is 2-4 mm.

[0055] Preferably, the support frame disposed inside the lower traction plate 210 is a sleeve structure that can extend outward, so that the lower traction plate can unfold a certain area below the aforementioned tissue.

[0056] Preferably, the support frame inside the lower traction plate is fan-shaped or arc-shaped.

[0057] Optionally, the support frame 213 is made of either rigid silicone or titanium. Preferably, the outer surface of the lower traction plate 210 is made of soft silicone or other biocompatible and environmentally friendly materials.

[0058] By way of example and not limitation, the upper traction plate 220 adopts negative pressure adsorption traction. The lower surface of the upper traction plate 220 is provided with a negative pressure suction cup 221, the upper layer of the upper traction plate 220 is provided with a negative pressure pipe 222, and the traction arm is provided with an air passage. The negative pressure pipe 222 is connected to an external negative pressure pump through the air passage.

[0059] Specifically, after the tissue near the incision is dissected, the lower traction plate 210 is inserted into the lower layer of the tissue. The sliding traction arm 223 is moved to place the upper traction plate 220 on top of the aforementioned tissue. Air is drawn out, creating a suitable negative pressure at the negative pressure suction cup 221, allowing the upper traction plate 220 to lift the tissue. The position of the sliding traction arm 223 is then fixed. In actual operation, the upper traction plate 220 and the lower traction plate 210 work together to control the tissue.

[0060] See Figure 5 The diagram shows a structural schematic of another traction assembly provided in an embodiment of the present invention. The upper traction plate is not shown in the figure. In this embodiment, the traction arm 130 is provided with an inflation / deflation air passage 212. One end of the inflation / deflation air passage 212 is connected to an air chamber 211 disposed inside the lower traction plate 210, and the other end of the inflation / deflation air passage 212 is connected to an external cylinder.

[0061] Preferably, the lower surface of the lower traction plate 210 is provided with a micro-inflator 214 for applying appropriate pressure to the bleeding site. The micro-inflator 214 is connected to the air chamber 211, but because the micro-inflator is small, it is inflated only after the air chamber is fully inflated. Specifically, when bleeding is detected in the surgical field, the external cylinder inflates the inflation / deflation airway 212 again, causing the micro-inflator 214 to inflate and thus apply pressure to stop the bleeding.

[0062] Preferably, a pressure sensor 215 is provided on the lower surface of the lower traction plate 210 to sense the pressure on the tissue and feed the pressure back to the control component.

[0063] In practical use, after the tissue near the incision is dissected, the lower traction plate 210 is inserted into the lower layer of the tissue, and the air chamber 211 is inflated. Preferably, the thickness of the inflated air chamber 211 is 2-3 mm. During inflation, the pressure sensor 215 feeds back the pressure exerted on the tissue to the control components. By way of example and not limitation, the pressure the tissue can withstand is between 0.5-2 N. When the tissue pressure exceeds 2 N, inflation will stop or the tissue will be deflated appropriately until the pressure exerted on the tissue is within a tolerable range.

[0064] Preferably, the incision operation requirement recognition component 400 includes an information acquisition device 410 and an information processing device 420. The information acquisition device 410 includes an image acquisition module 411, a patient information acquisition module 412, and a dynamic damage early warning component. The image acquisition module typically uses a camera for acquisition; the dynamic damage early warning component is used to obtain the probability of tissue damage risk by processing the aforementioned information.

[0065] Specifically, the probability of tissue damage risk is calculated using the following formula:

[0066]

[0067] Where D is the incision opening diameter, that is, the actual opening distance measured during the operation, and the value range is 20-100 mm;

[0068] D max， The maximum safe expansion diameter is determined by individual factors. This value is typically calculated using CT / MRI, and the average value for Asian women is 65 mm.

[0069] T is the duration of the expansion, specifically the duration of a single continuous expansion, with a value ranging from 10 to 180 minutes.

[0070] T crit The critical time for tissue tolerance is usually 90 min, which is the tissue ischemia threshold.

[0071] ΔP is the real-time pressure exceedance coefficient, where the measured pressure / safe pressure is ≥1.0, and the safe pressure is 15 kPa.

[0072] S represents the tissue elasticity score, with ultrasound elastography results ranging from 0 to 1 (1 = optimal). For younger patients, S is 0.8-1.0.

[0073] α is the tissue sensitivity coefficient, with a value ranging from 1.8 to 2.2;

[0074] β is the time decay coefficient, with a value ranging from 1.2 to 1.5;

[0075] γ is the pressure damage coefficient, with a value ranging from 1.3 to 1.7.

[0076] δ is the elastic protection coefficient, with a value range of 0.6-0.9 to 0.75.

[0077] Calculate the R-value to obtain different risk levels, as shown in the table below:

[0078]

[0079] Preferably, an early warning mechanism is set up so that an alarm is automatically triggered when the probability of tissue damage R is ≥ 0.7. The alarm can be a multi-level alarm, including but not limited to audible and visual alarms, automatic retraction of the traction arm, and display of the decompression scheme on a display device connected to the traction device.

[0080] Another embodiment of the present invention also provides a method for implementing a breast surgery traction device that reduces bodily damage.

[0081] See Figure 6 The diagram shown is a flowchart of the incision operation requirement identification process provided in an embodiment of the present invention. The process is configured to perform the following steps:

[0082] S01. Collect patient information through an information collection device;

[0083] S02. Set the threshold of the cut operation requirement recognition module according to the aforementioned information;

[0084] S03. Use the traction assembly to fix the position of the body tissues;

[0085] S04. Collect information on incision operation requirements and determine the incision operation requirements;

[0086] S05. The control component controls the traction component to appropriately change the size of the incision according to the requirements of the incision operation.

[0087] Combination Figure 7 The diagram shows a system diagram of a breast surgery traction device for reducing bodily damage provided in an embodiment of the present invention. Image data acquired by the image acquisition module 411 and patient information acquired by the patient information acquisition module 412 serve as data references for initially setting thresholds.

[0088] By way of example and not limitation, the patient information collected by the patient information collection module 412 includes, but is not limited to, the patient's name, age, gender, type of breast disease, skin elasticity, allergy history and other chronic diseases.

[0089] Based on the above information, a threshold for the incision operation requirement identification module is preset. This threshold includes one or more of the following: a time threshold, a displacement threshold, a bleeding threshold, and a tension threshold. The duration of the offset state must reach or exceed the preset time threshold. The offset state can be one of the following: the surgical instruments moving away from or near the incision; increased bleeding leading to blurred vision in the surgical field; etc.

[0090] Preferably, the time threshold is set to 1-2 minutes, and the displacement threshold is set to 5-8 centimeters. The surgical instruments may be scalpels, staplers, inserters, electrosurgical units, electromagnetic scalpels, etc.

[0091] The traction assembly 200 is used to fix the position of the tissue. Specifically, the upper traction plate 220 and the lower traction plate 210 are placed above and below the tissue being detached, so that the traction plate assembly can move the clamped tissue.

[0092] The camera records the incision site and its vicinity in real time. The information processing device 420 in the incision operation requirement recognition component 400 calculates and analyzes the position information of the surgical instrument relative to the aforementioned incision and the movement trend of the surgical instrument.

[0093] When the offset reaches the threshold, the trigger control component controls the traction component to appropriately change the opening size of the cut.

[0094] Preferably, a time threshold is set, i.e., the maximum time the offset state lasts. As an example, and not a limitation, the time threshold is set between 1 and 3 minutes. The offset state can be a change in the surgical field from a state with surgical instruments being used to a state without surgical instruments being used; in this case, the state without surgical instruments being used is the offset state. Alternatively, it can be a change in the surgical field from a state without surgical instruments being used to a state with surgical instruments being used; in this case, the state with surgical instruments being used is the offset state. Therefore, the offset state is the second state after the transition from the first state.

[0095] Specifically, initial thresholds are set based on the patient's age, gender, type of breast disease, skin elasticity, allergy history, and other chronic conditions. For example, consider a 50-year-old female patient who underwent breast cyst removal, had moderate skin elasticity, no allergy history, mild fatty liver, and glycosuria. Based on this information, analysis suggests that this patient may have weaker wound healing ability; therefore, stretching of the skin at the incision site should be minimized during surgery. Additionally, the patient may have coagulation abnormalities during surgery, and close monitoring of blood pressure is necessary.

[0096] Based on the above analysis, for the aforementioned patients, a relatively small time threshold and a relatively small bleeding threshold should be set. As an example, and not a limitation, the time threshold can be set to 1.5-2 minutes, and the bleeding threshold to 30%-35%. If the camera captures a transition within the surgical field from a state with surgical instruments to a state without surgical instruments, and the state without surgical instruments lasts for 2 minutes, the information processing device 420 considers the shift to have reached the preset time threshold. Then, the incision operation requirement recognition component 400 sends an operation execution command to the control component 300, indicating that the incision operation requirement is "closure." Correspondingly, the control component 300 controls the traction component 200, i.e., the traction arm and traction plate assembly, to perform the incision closure operation.

[0097] Specifically, the preset displacement threshold is 3 cm. If the camera captures the scalpel in the image moving away from the incision, in this case, when the distance between the scalpel and the incision reaches or exceeds 3 cm, it is determined that the incision operation requirement is "closed". At the same time, the incision operation requirement recognition component 400 sends the judgment result to the control component 300. The control component 300 performs a control operation according to the aforementioned judgment result, bringing together two or more traction arms 130 to close the aforementioned incision.

[0098] Similarly, when the camera captures a scalpel approaching the incision, and the distance between the scalpel and the incision reaches a displacement threshold of 3 centimeters, it is determined that the incision operation requirement is "opening". At the same time, the incision operation requirement recognition component 400 sends the judgment result to the control component 300. The control component performs a control operation based on the judgment result, moving two or more traction arms to open the incision.

[0099] Specifically, for the aforementioned patient, a bleeding threshold was set at 35% of the surgical field area occupied by free blood. When the camera detects that the area covered by free blood in the surgical field reaches or exceeds the bleeding threshold, the incision operation requirement recognition component 400 determines that the incision operation requirement is "closure." Simultaneously, the recognition module sends the judgment result to the control component, which executes a control operation based on the judgment result, converging and moving two or more traction arms to close the aforementioned incision. In addition, a miniature airbag located on the lower surface of the lower traction plate is rapidly inflated to apply pressure to the bleeding site for hemostasis.
