Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a skin flap retractor for breast cancer surgery. Background Art

[0002] In breast cancer surgery, a flap retractor is an important surgical tool used to pull and fix the flap so that the doctor can better observe and operate the surgical area. In breast cancer surgery, especially when it comes to flap incision, it often takes more than half an hour, so a retractor specifically for flaps is needed.

[0003] The flap retractor currently used mainly consists of a handle and a claw. When in use, the operator needs to hook the claw on the flap and then pull the handle outward to achieve the purpose of opening the flap. However, the entire operation process takes a long time. The operator will suffer arm soreness due to holding the flap retractor for a long time, and will not be able to accurately control the force of pulling the flap retractor, resulting in an uncertain size of the surgical opening, which affects the attending physician's observation and operation of the surgical area. Therefore, the present invention provides a flap retractor for breast cancer surgery to meet the demand. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a flap retractor for breast cancer surgery by setting an arc frame and a rebound frame. The flap retractor provided by the present application uses two arc frames to support and pull the position of the flap incision, and uses the airbag and the rebound frame to pull and stretch the flap incision. Such a pulling method is not only convenient and labor-saving to operate, but also the operator does not need to continuously hold and apply force with his hands during the actual operation, saving manpower and material resources, and the size of the flap incision opening is controlled according to the gas filled in the airbag. Such a setting makes the control of the opening size more stable and more accurate. The above setting can solve the problem that the existing flap retractor cannot accurately control the force of pulling the flap retractor during operation, resulting in uncertain size of the opening of the surgical area, affecting the attending physician's observation and operation of the surgical area.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A skin flap retractor for breast cancer surgery comprises an arc-shaped frame, both ends of the arc-shaped frame are provided with a third bending portion, the inner walls of both ends of the arc-shaped frame are fixedly connected with a rebound frame, an air bag is installed in the rebound frame, and a second joint is fixedly connected to the outer wall of the air bag; a drainage component, the drainage component is used to attract tissue fluid at the skin flap incision position, and the drainage component is respectively connected to the arc-shaped frame and the rebound frame.

[0006] Optionally, the drainage assembly includes a first bent portion fixedly connected to the bottom of the arc frame, a second bent portion fixedly connected to the bottom of the first bent portion, and also includes a first wrapping portion and a second wrapping portion fixedly connected to the top and bottom of the rebound frame, respectively. The same drainage tube is installed in the arc frame and the rebound frame, and a first joint is fixedly connected to the drainage tube.

[0007] Optionally, both the first bending portion and the second bending portion are arc-shaped bending structures, and the arc-shaped bending directions of the first bending portion and the second bending portion are opposite.

[0008] Optionally, the arc frame is a frame structure with an arc-shaped profile, the number of the arc frames is two, and pressure plates are symmetrically installed on the top of the arc frames.

[0009] Optionally, a drainage groove is provided on the inner wall of the first bending portion, and a drainage hole is provided through the drainage groove.

[0010] Optionally, a drainage head corresponding to the position of the drainage hole is fixedly connected to the outer wall of the drainage tube, the drainage head is inserted into the drainage hole, and the end of the drainage head is flush with the drainage groove.

[0011] Optionally, a segmented groove is provided on the rebound frame, and the rebound frame is an elastic structure with an “M”-shaped profile.

[0012] Optionally, the arc frame, the first bending portion and the second bending portion are integrally manufactured structures, and the rebound frame, the first wrapping portion and the second wrapping portion are integrally manufactured structures.

[0013] Optionally, two ends of the airbag are fixed to outer walls of the two arc-shaped frames in sequence, and the first wrapping portion and the second wrapping portion both have circular contours.

[0014] Optionally, the sizes of the second bending portion and the second wrapping portion are consistent with the sizes of the drainage tube.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, the flap retractor provided in the present application utilizes two arc-shaped frames to support and pull the position of the flap incision, and uses the airbag and the rebound frame to pull and stretch the flap incision. This pulling method is not only convenient and labor-saving to operate, but also the operator does not need to continuously hold and apply force with his hands during the actual operation, saving manpower and material resources. Moreover, the size of the flap incision opening is controlled according to the gas filled in the airbag. This setting makes the control of the opening size more stable and more accurate.

[0016] By setting up a drainage component, tissue fluid at the flap incision can be attracted, thereby preventing tissue fluid from accumulating near the flap hook during the entire operation, causing the flap hook to slip, and further affecting the pulling effect of the flap hook on the flap incision. The structure of the drainage component is hidden and stored in the arc frame and the rebound frame. This setting is not only convenient for operators to use the flap hook, but the hidden structure also makes the overall size of the flap hook smaller. The surgical field of view can be exposed as much as possible during the operation, thereby improving the efficiency and convenience of the operation.

[0017] By setting a first bending portion in the drainage component, the first bending portion has an arc that is concave in the opposite direction of the flap incision. When the arc frame is pressed against the outside of the flap incision, the incision tissue at the flap incision position is stored in the concave arc structure of the first bending portion. The concave arc structure of the first bending portion can wrap up the tissue at the incision, thereby limiting the tissue at the incision. This can effectively improve the stability of the cooperation between the flap hook and the tissue during the traction and expansion of the incision, prevent the flap hook from being dislocated and slipping during the traction and expansion process, and improve the convenience and success rate of the flap hook operation.

[0018] By setting a second bending portion in the drainage assembly, the arc-shaped contour of the second bending portion matches the size of the drainage tube, so the drainage tube can be placed in the second bending portion. Because the second bending portion has an arc-shaped contour in the opposite direction to the first bending portion, the drainage tube can avoid the tissue at the incision during placement and will not affect the limiting effect of the first bending portion on the tissue.

[0019] A rebound frame is arranged in the drainage component, the rebound frame is an elastic structure with an "M"-shaped profile, and the two ends of the rebound frame are respectively fixed on the outer walls of the two arc frames. Therefore, the rebound frame can exert an outward elastic force on the two arc frames. When the user places the arc frame in the flap incision for the first time, the arc frame will pull the closed flap incision to open a certain gap under the elastic action of the rebound frame. Segmented grooves are evenly opened on the rebound frame. The segmented grooves allow the rebound frame to deform at the position where the segmented grooves are opened, thereby improving the rebound deformation effect of the rebound frame and reducing the force required for the airbag to squeeze the rebound frame to deform.

[0029] like Figures 1 to 6As shown, an embodiment of the present invention provides a skin flap retractor for breast cancer surgery, comprising an arc frame 1, the number of the arc frames 1 is two, and the two ends of the arc frame 1 are respectively provided with a third bending portion 106, and the inner walls of the two ends of the arc frame 1 are fixedly connected with a rebound frame 2, and an airbag 4 is installed in the rebound frame 2, and the two ends of the airbag 4 are fixed on the outer walls of the two arc frames 1 in sequence, and the outer wall of the airbag 4 is fixedly connected with a second joint 401; a drainage component, the drainage component is used to attract tissue fluid at the position of the skin flap incision, and the drainage component is respectively connected to the arc frame 1 and the rebound frame 2. The skin flap retractor provided in the present application utilizes two arc frames 1 to support and pull the position of the skin flap incision, and uses the airbag 4 and the rebound frame 2 to open the skin flap incision. In the above scheme, the two arc frames 1 are fixedly connected with the inner walls of the two ends of the arc frame 1, and the airbag 4 and the rebound frame 2 are installed in the rebound frame 2. The frames 1 are placed on both sides of the flap incision, and the rebound frame 2 itself has a certain elastic force that can open a certain gap in the flap incision. Then the operator fills air into the airbag 4, and uses the expansion effect of the airbag 4 to unfold the rebound frame 2, and uses the supporting force of the rebound frame 2 and the airbag 4 to continuously expand the distance between the two arc frames 1, so that the two arc frames 1 pull the flap incision apart to achieve the effect of opening the flap incision. This pulling method is not only convenient and labor-saving to operate, but also the operator does not need to continuously use his hands to hold and apply force during the actual operation, saving manpower and material resources, and the size of the flap incision opening is controlled according to the gas filled in the airbag 4. This setting makes the control of the opening size more stable and more accurate.

[0030] By setting up a drainage component, the drainage component is set in the arc frame 1 and the rebound frame 2. The drainage component can attract tissue fluid at the flap incision position, thereby preventing tissue fluid from accumulating near the flap hook during the entire operation, causing the flap hook to slide, and further affecting the pulling effect of the flap hook on the flap incision. The structure of the drainage component is hidden and stored in the arc frame 1 and the rebound frame 2. Such a setting is not only convenient for the operator to use the flap hook, but the setting of the hidden structure makes the overall volume of the flap hook smaller. During the operation, the surgical field of view can be exposed as much as possible, thereby improving the operation efficiency and convenience of the operation.

[0031] As an implementation method in this embodiment, Figures 1 to 4As shown, the drainage component includes a first bending portion 101 fixedly connected to the bottom of the arc frame 1, and the bottom of the first bending portion 101 is fixedly connected to the second bending portion 102. The arc frame 1, the first bending portion 101 and the second bending portion 102 are an integrally manufactured structure. The arc frame 1 is a frame structure with an arc-shaped contour. The first bending portion 101 and the second bending portion 102 are both arc-shaped structures. The arc bending directions of the first bending portion 101 and the second bending portion 102 are opposite. A pressing plate 105 is symmetrically installed on the top of the arc frame 1. At this stage, the common flap incision is an arc-shaped incision. The incision is an arc-shaped incision centered on the nipple, which is also conducive to exposing and removing the mass. At the same time, taking into account the postoperative aesthetics and recovery, the flap retractor provided in the present application is suitable for the above-mentioned arc-shaped incision. The overall contours of the two arc-shaped frames 1 are arc-shaped, which are adapted to the contours of the arc-shaped incision, thereby ensuring that the incision is more evenly stressed during the process of the arc-shaped frame 1 pulling and stretching the incision, and the incision is opened more fully. Moreover, the two arc-shaped frames 1 can cooperate to completely pull the arc-shaped incision open. Compared with the prior art, there is no need to use multiple flap retractors to pull and open the incision, thereby reducing the investment in manpower and material resources.

[0032] Furthermore, the overall outline of the arc frame 1 consists of a first bend portion 101 and a second bend portion 102. The first bend portion 101 is located at the top of the arc frame 1. The first bend portion 101 has an arc that is concave in the opposite direction of the flap incision. When the arc frame 1 is pressed against the outside of the flap incision, the incision tissue at the flap incision position is stored in the concave arc structure of the first bend portion 101. The concave arc structure of the first bend portion 101 can wrap up the tissue at the incision, thereby limiting the tissue at the incision. This can effectively improve the stability of the cooperation between the flap hook and the tissue during the traction and stretching of the incision, prevent the flap hook from being dislocated and slipping during the traction and stretching process, and improve the convenience and success rate of the flap hook operation.

[0033] Furthermore, the second bending portion 102 is located at the bottom of the arc frame 1, and the arc-shaped contour of the second bending portion 102 is consistent with the size of the drainage tube 3, so the drainage tube 3 can be placed in the second bending portion 102. Because the second bending portion 102 has an arc-shaped contour in the opposite direction to the first bending portion 101, the drainage tube 3 can avoid the tissue at the incision during the placement process, and will not affect the limiting effect of the first bending portion 101 on the tissue. Since the arc frame 1, the first bending portion 101 and the second bending portion 102 are an integrated structure, and the three The materials of both are plastic, so the overall structure of the arc frame 1 can be integrally injection molded during the manufacturing process. This arrangement reduces the production process of the arc frame 1, making it easier to manufacture. Two pressing plates 105 are symmetrically installed on the top of the arc frame 1. When the user places the arc frame 1 at the patient's skin flap incision for the first time, the opening of the incision is relatively small, and the user needs to press the two arc frames 1. The user can apply pressure to the arc frame 1 with the help of the two pressing plates 105, which makes it more convenient to press the arc frame 1 and improves the efficiency of installing and removing the arc frame 1.

[0034] In this embodiment, if Figures 1 to 4 As shown, the same drainage tube 3 is installed in the arc frame 1 and the rebound frame 2, and the drainage tube 3 is fixedly connected with a first joint 301, and a drainage groove 103 is provided on the inner wall of the first bent portion 101, and a drainage hole 104 is penetrated in the drainage groove 103, and a drainage head 302 corresponding to the position of the drainage hole 104 is fixedly connected to the outer wall of the drainage tube 3, and the drainage head 302 is inserted into the drainage hole 104, and the end of the drainage head 302 is flush with the drainage groove 103. After the tissue at the flap incision is cut, tissue fluid will be secreted. Although the tissue fluid will not affect the operation, the accumulation of tissue fluid between the flap hook and the tissue will cause the flap hook to slip, thereby reducing the flap. The stability of the retractor. Since the tissue is contained in the arc-shaped contour of the first bend 101 and a drainage groove 103 is provided in the first bend 101, the tissue fluid secreted by the tissue will flow along the arc-shaped contour of the first bend 101 through the drainage groove 103 under the action of gravity and finally flow into the drainage hole 104 at the bottom of the drainage groove 103. The drainage head 302 on the drainage tube 3 is just plugged into the drainage hole 104. Therefore, when the user connects the first connector 301 to the external negative pressure equipment, the drainage head 302 will absorb the tissue fluid in the drainage hole 104 to prevent the tissue fluid from accumulating in the first bend 101 and avoid the flap retractor from slipping and becoming unstable.

[0035] In this embodiment, if Figures 1 to 6As shown, the drainage assembly also includes a first wrapping portion 201 and a second wrapping portion 202 respectively fixedly connected to the top and bottom of the rebound frame 2, a segmented groove 203 is provided on the rebound frame 2, the rebound frame 2 is an elastic structure with an "M"-shaped profile, the rebound frame 2, the first wrapping portion 201 and the second wrapping portion 202 are an integrally manufactured structure, the first wrapping portion 201 and the second wrapping portion 202 are both circular profiles, the sizes of the second bending portion 102 and the second wrapping portion 202 are consistent with the sizes of the drainage tube 3, because the rebound frame 2 is an elastic structure with an "M"-shaped profile and the two ends of the rebound frame 2 are respectively fixed on the outer walls of the two arc frames 1, the rebound frame 2 can apply an outward elastic force to the two arc frames 1, so that The arrangement is such that when the user places the arc frame 1 in the skin flap incision for the first time, the elastic action of the rebound frame 2 will cause the arc frame 1 to pull the closed skin flap incision open a certain gap. At this time, the second joint 401 on the airbag 4 is connected to the external air pump to inflate the airbag 4. Since the two ends of the airbag 4 are respectively fixed on the outer walls of the two arc frames 1, and the remaining part of the airbag 4 is not fixed to the rebound frame 2, the airbag 4 will exert a horizontal squeezing force on the rebound frame 2 after inflation. Under the action of the squeezing force, the rebound frame 2 is driven to deform and deform from an "M" shape to a straight shape. At this time, the distance between the two arc frames 1 will gradually increase, and the skin flap incision will also be pulled open by the two arc frames 1.

[0036] Specifically, segmented grooves 203 are evenly opened on the rebound frame 2. The opening of the segmented grooves 203 allows the rebound frame 2 to deform at the position where the segmented grooves 203 are opened, thereby improving the rebound deformation effect of the rebound frame 2 and reducing the force required for the airbag 4 to squeeze the rebound frame 2 to deform. The top and bottom of the rebound frame 2 are respectively fixed with the first wrapping part 201 and the second wrapping part 202. Both the first wrapping part 201 and the second wrapping part 202 have circular contours, and neither of them is a closed structure. A through groove is opened at the intersection of the first wrapping part 201 and the second wrapping part 202, so that the two are open circular contours at the same time. The user can use the open structure of the first wrapping part 201 and the second wrapping part 202 to place the airbag 4 and the drainage tube 3 in the first wrapping part 201 and the second wrapping part 202 respectively.

[0037] In summary, the drainage tube 3 is limited in the arc frame 1 and the rebound frame 2 by the second bending portion 102 and the second wrapping portion 202 respectively. This arrangement allows the accumulated fluid in the two arc frames 1 to be sucked out through one drainage tube 3, thereby reducing medical costs. The arc frame 1 and the rebound frame 2 have a reasonable structural layout and an ingenious structure, and both are one-piece manufactured structural settings, which are not only easy to produce but also simple and efficient during operation.

[0038] The working principle of the technical solution provided by the present invention is as follows: When in use, the operator presses the pressure plates 105 on the two arc frames 1 to cause the rebound frame 2 in the middle of the arc frames 1 to deform and shrink under pressure, thereby achieving the purpose of reducing the distance between the two arc frames 1 in turn, and then places the arc frame 1 at the position of the flap incision. Since the overall contours of the two arc frames 1 are arc-shaped, they are compatible with the contour of the arc-shaped incision. The first bending portion 101 has an arc that is concave in the opposite direction of the flap incision. When the arc frame 1 is pressed against the outside of the flap incision, the incision tissue at the flap incision position is stored in the concave arc structure of the first bending portion 101. The concave arc structure of the first bending portion 101 can wrap up the tissue at the incision, thereby limiting the tissue at the incision, which can effectively improve the incision. The stability of the cooperation between the flap hook and the tissue during the traction and stretching process prevents the flap hook from being dislocated and slipping during the traction and stretching process, and improves the convenience and success rate of the flap hook operation. After the arc frame 1 is placed, the second connector 401 on the airbag 4 is connected to the external air pump to inflate the airbag 4. Since the two ends of the airbag 4 are respectively fixed on the outer walls of the two arc frames 1, and the rest of the airbag 4 is not fixed to the rebound frame 2, the airbag 4 will exert a horizontal extrusion pressure on the rebound frame 2 after inflation. Under the action of the extrusion force, the rebound frame 2 is driven to deform and deform from an "M" shape to a straight shape. At this time, the distance between the two arc frames 1 will gradually increase, and the flap incision will also be pulled open by the two arc frames 1.

[0039] After the tissue at the flap incision is cut, tissue fluid will be secreted. Although the tissue fluid will not affect the operation, the accumulation of tissue fluid between the flap hook and the tissue will cause the flap hook to slip, thereby reducing the stability of the flap hook. Since the tissue is received in the arc-shaped contour of the first bending portion 101, and the drainage groove 103 is opened in the first bending portion 101, the tissue fluid secreted by the tissue will flow along the arc-shaped contour of the first bending portion 101 through the drainage groove 103 under the action of gravity and finally flow into the drainage hole 104 at the bottom of the drainage groove 103. 3 is just inserted into the drainage hole 104. Therefore, when the user connects the first connector 301 to the external negative pressure equipment, the drainage head 302 will absorb the tissue fluid in the drainage hole 104 to prevent the tissue fluid from accumulating in the first bending portion 101 and avoiding the flap hook from slipping and becoming unstable. The drainage tube 3 is respectively limited in the arc frame 1 and the rebound frame 2 by the second bending portion 102 and the second wrapping portion 202. Such an arrangement allows the accumulated fluid in the two arc frames 1 to be sucked out through one drainage tube 3, thereby reducing medical costs.

[0040] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
