Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a laparoscopic surgical field exposure device. Background Art

[0002] Surgery refers to the method by which surgeons use medical instruments such as scalpels to treat certain diseases. The visual field, also known as the field of view, refers to the range of vision of a normal person in a certain position. Therefore, the surgical field of view refers to the spatial range that surgeons can observe with normal vision during surgery. Whether the requirements for surgical field of view exposure can be met will directly affect the operation and effect of the surgery. The exposure problem during laparoscopic surgery is a problem that has always troubled clinicians. Since laparoscopic surgery is performed by punching holes in the abdominal wall and then inserting long-handled instruments to perform internal operations, effective traction exposure around the target organ is the first and most important step in removing the target organ.

[0003] At present, the commonly used method in clinical laparoscopic surgery is to use sutures as handles for traction, or to temporarily block with surgical instruments. The temporary blocking method with surgical instruments requires blocking while doing it, which has poor effect and slow speed. The method of using temporary sutures as handles to drag around organs that need to be pulled open, such as the intestine, and then removing the sutures after the operation increases additional suture trauma, and the suture and suture removal increase the operation time and increase additional surgical risks. At the same time, the exposure effect of using sutures to drag the surgical field is not ideal, and it cannot be adjusted at any time with the change of the surgical area. The operation needs to be suspended to adjust the position and direction of the sutures before the operation, which increases the workload of the operation and is very inconvenient to operate.

[0036] Example 1 The embodiment of the present invention provides a laparoscopic surgical field exposure device such as Figure 1As shown, it includes: a retraction structure and a clamping structure 2. The retraction structure is used to retract the epidermis of the organ to expose the surgical field of view. The retraction structure includes a first fixer 1 and a second fixer. The first fixer 1 is used to fix the organ to be retracted. The first fixer 1 is fixed to the target organ and is located inside the patient's abdominal wall. The second fixer is used to fix on the patient's abdominal wall and is located outside the patient's abdominal wall. The first fixer 1 is provided with a first magnet 11, and the second fixer is provided with a second magnet. The first magnet 11 and the second magnet are magnetically attracted to each other, and the first magnet 11 and the second magnet are attracted through the patient's abdominal wall. In actual use, the first magnet 11 and the second magnet in the device are magnets with sufficiently strong suction force. The first magnet 11 can also be an iron block. The position of the first fixer 1 inside the abdominal wall can be changed by moving the position of the second fixer outside the abdominal wall, thereby changing the retraction position. The clamping structure 2 is used to clamp the first fixator 1 in the retraction structure. When performing laparoscopic surgery, it is necessary to make a hole in the patient's abdominal wall for surgical operation. Therefore, it is also necessary to place the first fixator 1 on the target organ through the hole. The first fixator 1 is clamped by the clamping structure 2 to facilitate the delivery of the first fixator 1 to the required position. The clamping structure 2 includes a connecting rod 21, an angle adjustment assembly and a clamping head 22. When in use, a connecting tube is usually placed at the position of the hole made in the abdominal wall. The connecting rod 21 passes through the connecting tube and can be placed in the connecting tube. The clamping head 22 is arranged at one end of the connecting rod 21. The clamping head 22 is hinged to the connecting rod 21 and can rotate relative to the connecting rod 21. The clamping head 22 is used to clamp the first fixator 1. The angle adjustment assembly is arranged between the connecting rod 21 and the clamping head 22. The angle adjustment assembly is used to adjust the angle of the clamping head 22, so as to facilitate the adjustment of the position required to be retracted. When the device is in use, the clamping structure 2 clamps the first fixator 1 through the hole punched in the abdominal wall. First, the angle of the clamping head 22 is adjusted through the angle adjustment component to adjust the position of the first fixator 1, so that the first fixator 1 is fixed to the epidermis of the organ that needs to be retracted. Then the second fixator is placed outside the patient's abdominal wall. Secondly, the position of the first fixator is adjusted by moving the second fixator, so that it is convenient for medical staff to operate on the surface of the patient's abdominal wall to change the retraction angle, position, etc.The device can adjust the angle of the clamping head 22 through the angle adjustment component, thereby adjusting the position where the first fixator 1 is fixed to the organ. A second fixator adsorbed on the first fixator 1 is also provided. The first fixator 1 used to retract the epidermis of the organ can be moved by moving the second fixator on the surface of the patient's abdominal wall. The retraction position can be adjusted by the above two methods before the operation to adjust it to the position of the surgical field to be exposed. During the operation, when the position of the exposed surgical field needs to be adjusted as the surgical area changes, the second fixator can be moved to adjust the position of the epidermis of the retracted organ, and the position where the first fixator 1 is fixed to the organ can also be adjusted by adjusting the angle of the clamping head 22 at the same time. The device is convenient for medical staff to operate on the surface of the patient's abdominal wall to change the retraction angle, position, etc., and can be adjusted as the surgical area changes, while making the surgical field exposure effect better.

[0037] This embodiment provides a specific structure of a first fixture 1, such as Figure 2 As shown, further, the first fixer 1 includes: a fixed block 12, a clamping hook 13, and a first driving member. A first magnet 11 is provided on one side of the fixed block 12. Two clamping hooks 13 are symmetrically arranged, and the two clamping hooks 13 are located on the side of the fixed block 12 away from the first magnet 11. A slide groove 121 is provided on the other side of the fixed block 12, and one of the clamping hooks 13 is slidably connected to the slide groove 121. The two clamping hooks 13 are used to clamp the epidermis of the organ that needs to be pulled open, and the epidermis of the organ is clamped by the two clamping hooks 13 to avoid damage to the epidermis of the patient's organ. The first driving member has an output end, and the output end of the first driving member is connected to one of the clamping hooks 13, and the first driving member is used to drive the clamping hook 13 to slide in the slide groove 121. In this embodiment, when the first fixator 1 enters the patient's abdominal wall, two clamping hooks 13 are used to clamp the epidermis of the patient's internal organs. Specifically, the first driving member drives the clamping hook 13 to slide in the slide groove 121, thereby changing the distance between the two clamping hooks 13 to clamp the epidermis of the organ. Currently, most of the fixation with the epidermis of the organ adopts puncture hooks or sutures, which will cause trauma to the epidermis of the patient's internal organs. This device uses two clamping hooks 13 to clamp the epidermis of the patient's internal organs to avoid causing wounds to the epidermis of the organ. Among them, the second fixator can also be set as a block, and a second magnet is set at one end of the block, so that the second magnet and the first magnet 11 are magnetically attracted to each other through the abdominal wall.

[0038] This embodiment provides a specific structure of a first driving member. Furthermore, the first driving member is an electric telescopic rod, which is arranged in a slide groove 121. The free end of the electric telescopic rod is connected to the clamping hook 13. The telescopic direction of the free end of the electric telescopic rod is consistent with the length direction of the slide groove 121. The electric telescopic rod is used to drive the clamping hook 13 to slide in the slide groove 121. Specifically, the free end of the electric telescopic rod is stretched, driving one of the clamping hooks 13 to slide in the slide groove 121 and approach the other clamping hook 13 to clamp the epidermis of the organ. The free end of the electric telescopic rod is contracted, driving the clamping hook 13 to move away from the other clamping hook 13, loosening the clamping of the epidermis of the organ, and facilitating the change of the clamping position. Among them, the electric telescopic rod can also be replaced by a structure with a telescopic function such as an electric push rod and a hydraulic rod.

[0039] like Figure 2 As shown, further, the clamping hook 13 is a first bending rod 131, one end of the first bending rod 131 is arranged on the side wall of the fixing block 12, and the bending parts of the first bending rods 131 of the two clamping hooks 13 are arranged opposite to each other, so that the two ends of the two first bending rods 131 are arranged away from each other, and the free end of the electric telescopic rod is connected to the side wall of one of the first bending rods 131. Figure 2 It can be seen that the bending parts of the two first bending rods 131 of the device are arranged opposite to each other, and when clamping the epidermis of the organ, it is clamped by the bending parts of the two first bending rods 131. Among them, the bending parts of the two first bending rods 131, that is, the contact surface with the epidermis of the organ, are designed to be smooth to avoid iatrogenic damage.

[0040] In the above solution, if the two first bending rods 131 loosen the organ epidermis, it will affect the operation. In order to clamp more firmly, Figure 2 As shown, further, it also includes: two second bending rods 132 are respectively arranged at the ends of the two first bending rods 131 away from the fixed block 12, and the ends of the two second bending rods 132 away from the first bending rod 131 are consistent with the length direction of the slide slot 121, and the end of one of the second bending rods 132 away from the first bending rod 131 is provided with a third magnet 133, and the end of the other second bending rod 132 away from the first bending rod 131 is provided with a fourth magnet 134, and the third magnet 133 and the fourth magnet 134 are magnetically adsorbed. In order to make the two first bending rods 131 more stable when clamping, after the bending parts of the two second bending rods 131 clamp the epidermis of the organ, the third magnet 133 and the fourth magnet 134 on the two second bending rods 132 are also magnetically adsorbed together, and the magnetic force is used to increase the clamping force of the two first bending rods 131, so that the clamping can be more stable, and the situation that the two first bending rods 131 loosen the epidermis of the organ during surgery is avoided.

[0041] Example 2 As a further improvement scheme based on Example 1, this embodiment provides a specific structure of a clamping head 22. Furthermore, the clamping head 22 includes: a connecting block 221, a first support rod 223, and a spring clip 224. The connecting block 221 is connected to the end of the connecting rod 21 through an angle adjustment assembly, and the angle adjustment assembly adjusts the angle of the connecting block 221 relative to the connecting rod 21. One end of the first support rod 223 is arranged on the side of the connecting block 221 away from the connecting rod 21. The provision of the first support rod 223 can extend the position of the first fixator 1 to retract the organ epidermis, thereby expanding the retraction range, which is conducive to adjusting the position of the exposed surgical field of view. The spring clip 224 is arranged at the other end of the first support rod 223. The spring clip 224 is used to clamp the fixing block 12, such as Figure 3 As shown, the structure of the spring clip 224 is similar to existing clips or dovetail clips, and can clamp the side wall of the fixing block 12 to clamp the first fixture 1. The clamping head 22 in this embodiment can clamp the first fixture 1, and the spring clip 224 clamps the side wall of the fixing block 12, which is convenient for medical staff to operate. At the same time, the first support rod 223 can extend the position of the first fixture 1 to retract the organ epidermis, thereby expanding the retractable range, which is conducive to adjusting the position of the exposed surgical field.

[0042] Among them, other structures of this embodiment are consistent with those of embodiment 1, and are just optimizations made to embodiment 1.

[0043] Example 3 As a further improvement on Example 2, this embodiment provides a specific structure of an angle adjustment component, such as Figure 4As shown, further, the angle adjustment assembly includes: a flexible connector 23, a support plate 24, a second drive member 25, a rotating shaft 26, a rotating disk 27, and a second support rod 28. The flexible connector 23 has two ends, and the two ends of the flexible connector 23 are respectively connected to the side walls of the connecting block 221 and the connecting rod 21. The flexible connector 23 can be a hose or a connecting belt or a metal telescopic tube, etc., or other flexible connectors 23 can be used. The above-mentioned flexible connectors 23 are all flexible, and will not affect the connecting rod 21 when the angle of the connecting block 221 changes, so as to facilitate the adjustment of the position of the connecting block 221. If the metal telescopic tube can adjust the position of the connecting block 221 and has a certain supporting force, a suitable flexible connector 23 can be selected according to actual conditions. The support plate 24 is fixed on the side wall of the connecting rod 21, and the support plate 24 is horizontally arranged in the same direction as the length of the connecting rod 21. The support plate 24 is located below the flexible connector 23. The second drive member 25 is arranged on the support plate 24, and the second drive member 25 has an output end. The rotating shaft 26 is vertically arranged at the output end of the second driving member 25. The second driving member 25 is used to drive the rotating shaft 26 to rotate. The second driving member 25 is a driving motor or a steering gear or other rotating driving structure. The turntable 27 is eccentrically arranged at the top of the rotating shaft 26. Specifically, the circumferential side wall of the rotating disk 27 is fixed to the top of the rotating shaft 26. The rotating shaft 26 can drive the rotating disk 27 to rotate. The second support rod 28 is vertically arranged. One end of the second support rod 28 is fixed to the circumference of the rotating disk 27. The second support rod 28 is located on the side of the rotating disk 27 away from the rotating shaft 26. The other end of the second support rod 28 is hinged to the side wall of the connecting block 221, and the hinge can be realized by a hinge. When adjusting the angle, the angle adjustment component in this embodiment controls the second driving member 25 to work, drives the rotating shaft 26 to rotate, thereby rotating the rotating disk 27, driving the second support rod 28 on the rotating disk 27 to rotate, thereby driving the connecting block 221 to rotate and change the angle, so as to adjust the angle of the first fixture 1.

[0044] The above scheme realizes the adjustment of the angle of the connecting block 221 in the horizontal direction. In order to expand the adjustable range, further, the rotating shaft 26 is a hydraulic rod, and the hydraulic rod can also be replaced by an electric telescopic rod, an electric cylinder, an electric push rod and other structures with electric telescopic functions. The second support rod 28 is a telescopic rod, and the telescopic rod is a common structure with a telescopic function. When the rotating shaft 26, that is, the free end of the hydraulic rod, is telescopic, it drives the turntable 27 to move upward or downward synchronously, and the second support rod 28, that is, the telescopic rod, moves upward or downward accordingly, driving the position change of the connecting block 221 in the vertical direction, thereby expanding the adjustable range and more flexibly adapting to changes in the surgical area. Among them, the hydraulic rod is the active part, the telescopic rod is the driven part, and the rotating shaft 26 is a hydraulic rod and the second support rod 28 is a hydraulic rod.

[0045] In order to better expose the surgical field, Figure 1As shown, further, the first support rod 223 is provided with a plurality of Figure 4 As shown, a groove 225 is provided at one end of the connecting block 221 away from the connecting rod 21, so that the connecting block 221 is C-shaped, and a fixed shaft 226 is vertically arranged in the groove 225, and both ends of the fixed shaft 226 are fixed to the two side walls of the groove 225, and multiple first support rods 223 are respectively mounted on the fixed shaft 226, and multiple first support rods 223 are respectively rotatably connected to the fixed shaft 226, and the first support rod 223 and the fixed shaft 226 are clearance-matched. In actual applications, there is a slight clearance between the first support rod 223 and the fixed shaft 226, so that the first support rod 223 can be rotated on the fixed shaft 226. In this embodiment, a plurality of first support rods 223, that is, a plurality of spring clips 224 and a first fixer 1 are provided. Before use, the plurality of first support rods 223 can be overlapped and inserted into the punched holes, and the angle of the connecting block 221 can be adjusted. At the same time, the plurality of first support rods 223 can be rotated by using surgical instruments, and the plurality of first support rods 223 can be distributed at positions where organs need to be retracted, so that a large range of retraction can be achieved, thereby making the exposure effect of the surgical field of view better.

[0046] like Figure 1 As shown, further, the first support rod 223 includes a plurality of rod bodies connected end to end in sequence, and two adjacent rod bodies are hinged, and the hinge can be realized by a pin shaft, and the rod body at one end is fixed to the spring clip 224, that is, the first support rod 223 is a foldable rod as a whole, and the rod body at the other end is sleeved on the fixed shaft 226. In this embodiment, the first support rod 223 is set as a multi-section foldable rod, which can be more flexibly adapted to the target organ, and is convenient for adjusting the first fixator 1 to the position where the organ needs to be retracted.

[0047] Among them, the other structures of this embodiment are consistent with those of Embodiment 2, and are just optimizations made to Embodiment 2.

[0048] According to the above-mentioned embodiment 1, embodiment 2, and embodiment 3, the method for using the device includes the following steps: Step 1: Use the spring clip 224 to clamp the fixing block 12 .

[0049] Step 2: Pass the entire clamping structure 2 through the hole punched on the patient's abdominal wall so that the connecting block 221 is located in the patient's abdominal cavity.

[0050] Step 3: adjust the angle of the connection block 221 through the angle adjustment assembly, and rotate the plurality of first support rods 223 at the same time, so that the fixing block 12 connected to the plurality of first support rods 223 is located near the epidermis where the organ needs to be pulled open.

[0051] Step 4: Use the two clamping hooks 13 on the fixing block 12 to clamp the epidermis of the organ that needs to be pulled open.

[0052] Step 5: Place the second fixator on the patient's abdominal wall so that the second magnet on the second fixator is magnetically attracted to the first magnet 11 , and adjust the angle of pulling the epidermis of the organ by adjusting the position of the second fixator.
