Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an incision retractor fixator. Background Art

[0002] Abdominal and abdominal surgeries are aimed at diseases inside the chest and abdominal cavities. They are performed after the cortical tissue of the chest and abdominal cavities is cut open. With the development of thoracoscopic equipment and technology, thoracoscopic surgery has been widely used in the diagnosis and treatment of chest diseases. At the same time, during the operation, the incision is opened with an incision retractor, which is more minimally invasive and minimizes the impact of the surgery on the intercostal nerves. It has obvious advantages in reducing postoperative incision pain and chest wall paresthesia, shortening the patient's postoperative recovery period.

[0003] Currently, during thoracic and abdominal incision surgeries, the operator holding the scope needs to adjust the lens distance, focus and clarity in a timely and accurate manner according to the surgeon's requirements for surgical details. At the same time, the operator is also required to avoid collisions with instruments as much as possible. However, if the operator holds the scope for a long time, it is inevitable that the operator's operating accuracy will decrease due to fatigue, which will affect the normal progress of the operation. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides an incision retractor fixator, which solves the problem that the operator's operating accuracy will inevitably decrease due to fatigue after holding the scope for a long time, thus affecting the normal progress of the operation.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an incision retractor fixator, comprising an upper ring body, a lower ring body and an elastic support membrane connecting the upper ring body and the lower ring body, a top ring is provided on the top of the upper ring body, an operating ring is provided on the side of the top ring facing away from the upper ring body, an annular groove is provided on the side of the top ring facing the operating ring, an annular slider is slidably connected in the annular groove, the annular slider extends out of the annular groove, the part of the annular slider extending out of the annular groove is fixedly connected to the operating ring, a lap platform is fixed on the inner side wall of the operating ring, and an A limit ring and a B limit ring for accommodating an endoscope and a suction device are fixed on the lap platform.

[0008] Through the above technical scheme, the top ring, the upper ring body, the elastic support membrane and the lower ring body are an integrated structure. The A limit ring and the B limit ring are respectively used to accommodate the data transmission line of the endoscope and the negative pressure suction tube for smoke exhaust, and play a limiting role on the data transmission line and the negative pressure suction tube of the endoscope, thereby reducing the possibility of instrument collision between the data transmission line and the negative pressure suction tube of the endoscope during surgery and affecting the surgery. Through the cooperation of the overlapping platform, the A limit ring and the B limit ring, the data transmission line and the negative pressure suction tube of the endoscope can be simply placed, reducing the problem of fatigue of the operator holding the mirror for a long time and resulting in a decrease in operating accuracy. Through the cooperation of the annular slider and the annular slide groove, the data transmission line and the negative pressure suction tube of the endoscope can be adjusted according to needs during surgery.

[0009] Preferably, the overlapping platform consists of an inclined first overlapping platform and a straight second overlapping platform, and the first overlapping platform and the second overlapping platform are an integrated structure.

[0010] Through the above technical solution, the data transmission line of the endoscope is usually placed at an angle, and a bonding platform is formed by the first bonding platform and the second bonding platform to support the data transmission line and improve the comfort of the person holding the endoscope.

[0011] Preferably, the top opening diameter of the annular slide groove is smaller than the bottom diameter, and a plurality of balls are movably connected in the annular slide groove, and a plurality of the balls are in conflict with the annular slider.

[0012] Through the above technical solution, since the top diameter of the annular groove is smaller than the bottom diameter, the ball will not fall out of the annular groove, and the smoothness of the rotation of the operating ring is improved through the cooperation of the ball and the annular slider.

[0013] Preferably, the circumferential outer wall of the top ring is provided with a plurality of waist-shaped holes, which are arranged in an array with the center line of the operating ring as the center of the circle, and the circumferential outer wall of the operating ring is provided with a control component which is plugged into and connected to one of the waist-shaped holes to limit the position of the operating ring.

[0014] Through the above technical solution, the operating ring moves with the movement of the data transmission line and the negative pressure suction tube of the endoscope during the operation. When the data transmission line and the negative pressure suction tube of the endoscope need to maintain the same position for a long time, the operating ring is limited by the control part, thereby further reducing the possibility that the data transmission line of the endoscope will be offset and affect the operation due to fatigue of the person holding the endoscope due to long-term support of the data transmission line of the endoscope.

[0015] Preferably, the control member includes a support fixed on the circumferential outer wall of the operating ring, a connecting rod is hingedly connected to the support, a wedge-shaped head is provided at one end of the connecting rod facing the top ring, a column block is integrally formed at one end of the connecting rod away from the wedge-shaped head, a connecting column is provided on the outer sleeve of the wedge-shaped head, a plug matching the waist-shaped socket is fixed at one end of the connecting column facing the waist-shaped socket, a groove matching the wedge-shaped head and the column block is provided on the connecting column, the connecting column is movably connected to the wedge-shaped head and the column block, and the connecting rod is fixed to the support by a spring.

[0016] Through the above technical solution, the connecting rod is supported by the support, and the rotation of the connecting rod is limited by the spring. The rotation of the connecting rod will drive the connecting column and the plug to move in the horizontal direction, thereby driving the plug to enter the waist-shaped socket or move out of the waist-shaped socket.

[0017] Preferably, baffles are fixed on both sides of the support, and the two baffles are respectively located on the left and right sides of the connecting rod.

[0018] Through the above technical solution, by setting the baffle, the possibility of medical staff accidentally touching the connecting rod and affecting the position of the operating ring is reduced.

[0019] Preferably, a limiting rod is fixed between the two baffles, and the limiting rod is horizontally arranged and located between the connecting rod and the support.

[0020] Through the above technical solution, the rotation angle of the connecting rod is limited by setting a limit rod, thereby reducing the possibility of affecting the operating ring, the top ring, the upper ring body, the elastic support membrane and the lower ring body during pressing the connecting rod.

[0021] (III) Beneficial effects

[0022] The utility model provides an incision retractor fixator, which has the following beneficial effects:

[0023] (1) The incision retractor fixator has an integrated structure of a top ring, an upper ring body, an elastic support membrane and a lower ring body. The A limit ring and the B limit ring are respectively used to accommodate the data transmission line of the endoscope and the negative pressure suction tube for smoke exhaust, and play a limiting role on the data transmission line of the endoscope and the negative pressure suction tube, thereby reducing the possibility of instrument collision between the data transmission line of the endoscope and the negative pressure suction tube during the operation and affecting the operation. Through the cooperation of the lap platform, the A limit ring and the B limit ring, the data transmission line and the negative pressure suction tube of the endoscope can be easily placed, reducing the problem of fatigue of the operator holding the endoscope for a long time and resulting in a decrease in operating accuracy.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-7 As shown, the utility model provides a technical solution: an incision retractor fixator, comprising an upper ring body 1, a lower ring body 2 and an elastic support membrane 3 connecting the upper ring body 1 and the lower ring body 2, the upper ring body 1 and the lower ring body 2 are both silicone rings, a top ring 4 is provided on the top of the upper ring body 1, an operating ring 5 is provided on the side of the top ring 4 facing away from the upper ring body 1, the upper ring body 1, the elastic support membrane 3 and the lower ring body 2 are an integrated structure and the center lines coincide, a plurality of slots are provided on the upper ring body 1, a plurality of plug posts adapted to the plug holes are provided on the side of the top ring 4 facing the upper ring body 1, the top ring 4 and the operating ring 5 are connected to the upper ring body through the plug posts and the slots as matching structures with the upper ring body 1, the elastic support membrane 3 and the lower ring body 2, an annular slide groove 6 is provided on the side of the top ring 4 facing the operating ring 5, an annular slide block 7 is slidably connected in the annular slide groove 6, the annular slide block 7 extends out of the annular slide groove 6, and the annular slide block 7 extends out of the annular slide groove 6 The part is fixedly connected to the operating ring 5, and a lap platform 8 is fixed to the inner wall of the operating ring 5. A limiting ring 9 for accommodating the data transmission line of the endoscope and B limiting ring 10 for accommodating the negative pressure suction tube for smoke exhaust are fixed on the lap platform 8. The A limiting ring 9 and the B limiting ring 10 respectively limit the data transmission line of the endoscope and the negative pressure suction tube, thereby reducing the possibility of instrument collision between the data transmission line of the endoscope and the negative pressure suction tube and affecting the operation during the operation. Through the cooperation of the lap platform 8, the A limiting ring 9 and the B limiting ring 10, the data transmission line of the endoscope and the negative pressure suction tube are simply placed, thereby reducing the problem of fatigue of the operator holding the mirror for a long time and resulting in a decrease in operating accuracy. Through the cooperation of the annular slider 7 and the annular groove 6, the data transmission line of the endoscope and the negative pressure suction tube can be adjusted according to needs during the operation.

[0035] like Figure 5 The overlapping platform 8 is composed of an inclined first overlapping platform 801 and a straight second overlapping platform 802. The first overlapping platform 801 and the second overlapping platform 802 are an integrated structure. Usually, the data transmission line of the endoscope is placed at an angle. The overlapping platform 8 is formed by the first overlapping platform 801 and the second overlapping platform 802 to support the data transmission line and improve the comfort of the person holding the endoscope.

[0036] like Figure 3 and Figure 4 In order to improve the smoothness of the rotation of the operating ring 5, the top opening diameter of the annular groove 6 is smaller than the bottom diameter. A plurality of balls are movably connected in the annular groove 6, and the plurality of balls are in conflict with the annular slider 7. Since the top diameter of the annular groove 6 is smaller than the bottom diameter, the balls will not fall out of the annular groove 6.

[0037] like Figure 1 and Figure 2 and Figure 3 and Figure 4A plurality of waist-shaped holes 11 are provided on the circumferential outer wall of the top ring 4, and the plurality of waist-shaped holes 11 are arranged in an array with the center line of the operating ring 5 as the center of the circle. A control member 12 is provided on the circumferential outer wall of the operating ring 5, which is plugged into one of the waist-shaped holes 11 to limit the position of the operating ring 5. The operating ring 5 moves with the movement of the data transmission line of the endoscope and the negative pressure suction tube during the operation. When the data transmission line and the negative pressure suction tube of the endoscope need to maintain the same position for a long time, the operating ring 5 is limited by the control member 12, thereby further reducing the possibility that the data transmission line of the endoscope may be offset and affect the operation due to fatigue of the person holding the endoscope due to long-term support of the data transmission line of the endoscope.

[0038] like Figure 6 and Figure 7 The control member 12 includes a support 1201 fixed to the outer wall of the circumference of the operating ring 5, and a connecting rod 1202 is hingedly connected to the support 1201. A wedge-shaped head 1203 is provided at one end of the connecting rod 1202 facing the top ring 4, and a columnar block 1204 is integrally formed at one end of the connecting rod 1202 away from the wedge head 1203. A connecting column 1205 is provided on the outer sleeve of the wedge head 1203. A plug 1206 adapted to the waist-shaped socket 11 is fixed at one end of the connecting column 1205 facing the waist-shaped socket 11, and a plug 1206 adapted to the waist-shaped socket 11 is provided on the connecting column 1205. The groove 1207 is adapted to the column block 1204, the connecting column 1205 is movably connected to the wedge head 1203 and the column block 1204, the connecting rod 1202 is fixed to the support 1201 by a spring 1208, the connecting rod 1202 is supported by the support 1201, and the spring 1208 limits the rotation of the connecting rod 1202. The rotation of the connecting rod 1202 will drive the connecting column 1205 and the plug 1206 to move in the horizontal direction, thereby driving the plug 1206 to enter the waist-shaped socket 11 or move out of the waist-shaped socket 11.

[0039] like Figure 6 and Figure 7 Since the size of the waist-shaped socket 11 is larger than that of the plug 1206, when the connecting column 1205 and the plug 1206 are offset in the vertical direction, it does not affect the plug 1206 from entering or moving out of the waist-shaped socket 11, thereby reducing the possibility of affecting the surgical progress due to adjusting the position of the operating ring 5 during the operation.

[0040] like Figure 6 and Figure 7 In order to reduce the possibility that medical staff may accidentally touch the connecting rod 1202 and affect the position of the operating ring 5 , baffles 1209 are fixed on both sides of the support 1201 , and the two baffles 1209 are respectively located on the left and right sides of the connecting rod 1202 .

[0041] like Figure 6 and Figure 7In order to reduce the possibility of affecting the operating ring 5, the top ring 4, the upper ring body 1, the elastic support membrane 3 and the lower ring body 2 during the process of pressing the connecting rod 1202 hard, a limiting rod 1210 is fixed between the two baffles 1209. The limiting rod 1210 is horizontally arranged and located between the connecting rod 1202 and the support 1201.

[0042] When in use, the staff pinches the bottom of the integrated structure formed by the upper ring body 1, the elastic support membrane 3 and the lower ring body 2 into an oblate shape, and then sends the lower ring body 2 and the elastic support membrane 3 into the surgical incision. Subsequently, the lower ring body 2 and the elastic support membrane 3 inside the incision are restored to a ring shape by their own elasticity. At this time, the position of the upper ring body 1 is simply adjusted, and the endoscope is sent into the patient's body through the A limit ring 9. The endoscope data transmission line is overlapped in the A limit ring 9. According to the needs of the surgical field of view, the operating ring 5 is rotated. The rotation of the operating ring 5 will drive the overlap platform 8 fixedly connected to the operating ring 5 to rotate, and at the same time, it will drive the position of the A limit ring 9 fixed to the overlap platform 8 until the surgical field of view meets the doctor's operating needs. The rotation of the operating ring 5 is guided by the cooperation of the annular slider 7 and the annular slide groove 6.

[0043] At the same time, when the operating ring 5 rotates, the staff presses the connecting rod 1202, and the spring 1208 is compressed. The rotation of the connecting rod 1202 will drive the connecting column 1205 and the plug 1206 movably connected to the connecting rod 1202 to move in the horizontal direction. The plug 1206 is not connected to the waist-shaped socket 11 until the operating ring 5 moves to the required position. The staff releases the connecting rod 1202, and the spring 1208 rebounds, driving the connecting column 1205 and the plug 1206 to move in the horizontal direction to the adjacent waist-shaped socket 11. At this time, the operating ring 5 is limited to reduce the possibility of the endoscope data transmission line being offset and affecting the surgical field of view due to fatigue of the person holding the mirror for a long time. This is the use process of the incision retractor. At the same time, the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
