[0021] The present utility model will be further described below with reference to the embodiments.
[0022] Embodiment: Refer to Figures 1 to 3 , a laparoscopic trocar stabilizing device, which includes a channel base 1. A channel tube 11 is connected to the bottom of the channel base 1. A trocar base 2 is detachably installed on the top of the channel base 1. A trocar rod 21 is fixedly installed at the bottom of the trocar base 2, and the bottom end of the trocar rod 21 movably penetrates through the channel base 1 and the channel tube 11. An air injection valve 3 is arranged on the outer side of the channel base 1. The bottom of the channel base 1 is detachably installed with a fixing plate 4 through a fixing component. A threaded block 41 is fixedly installed at the bottom of the fixing plate 4. A threaded sleeve 42 is threadedly sleeved on the outer side of the threaded block 41. A tape 43 is movably sleeved on the outer side of the threaded sleeve 42. During use, first, the fixing plate 4 is installed at the bottom of the channel base 1 through the fixing component, then the channel tube 11 and the trocar rod 21 are inserted into the abdomen, and then the threaded sleeve 42 is rotated. By using the threaded connection between the threaded sleeve 42 and the threaded block 41, the position of the threaded sleeve 42 is adjusted so that the bottom of the threaded sleeve 42 contacts the human skin, and then the tape 43 is pasted on the patient's skin, thereby being able to fix the channel base 1 and achieving better stability of the channel tube 11 after being inserted into the human body and improving the surgical safety.
[0023] The fixing assembly includes a plurality of arc plates 5 fixedly installed and distributed in a circular array on the top of the fixing plate 4, an arc groove 51 engaged with the arc groove 5 is provided at the bottom of the channel seat 1 and at the corresponding position of the arc plate 5, a clamping groove 52 is provided on the inner wall of one side of the arc groove 51, a clamping block 53 is slidably connected inside the clamping groove 52, a clamping hole 54 engaged with the clamping block 53 is provided on one side of the arc plate 5 and at the corresponding position of the clamping block 53, a driving plate 55 is fixedly installed on the top of the plurality of clamping blocks 53, a sliding groove 56 slidably connected with the driving plate 55 is provided inside the channel seat 1 and at the corresponding position of the driving plate 55. When installing the fixing plate 4, the driving plate 55 is first rotated to drive the plurality of clamping blocks 53 at the bottom to rotate simultaneously, at this time the clamping block 53 is inside the clamping groove 52, and then the plurality of arc plates 5 on the top of the fixing plate 4 are inserted into the arc groove 51, and then the driving plate 55 is reset to insert the plurality of clamping blocks 53 at the bottom into the clamping hole 54 provided on one side of the arc plate 5, so that the fixing plate 4 can be fixed.
[0024] A spring 6 is fixedly installed on the inner wall of one side of the slot 52, and the other end of the spring 6 is fixedly connected to the opposite side of the block 53. The elastic force of the spring 6 limits the position of the block 53 to prevent the block 53 from escaping from the hole 54, thereby improving the fixing effect of the device.
[0025] A soft material is fixedly installed at the bottom of the threaded sleeve 42. The soft material includes one of medical silica gel, medical foam and medical gel, which can reduce the friction between the device and the human body and improve the comfort of the patient.
[0026] The tape 43 is in a petal structure, and there is a certain gap between each sticky surface of the tape 43. The petal-shaped design can better adapt to the curve of the skin, reduce discomfort to the skin, and provide a more comfortable fit.
[0027] The outer side of the channel tube 11 is provided with anti-slip grooves 12 to increase the friction between the channel tube 11 and the abdominal wall, thereby preventing the channel tube 11 from being squeezed out of the abdomen under the action of abdominal cavity gas pressure, and improving the stability and safety of the operation.
[0028] The working principle of the present utility model is as follows: When in use, first rotate the driving plate 55 to drive multiple clamping blocks 53 at the bottom to rotate simultaneously. At this time, the clamping blocks 53 are inside the clamping grooves 52. Then insert multiple arc-shaped plates 5 at the top of the fixing plate 4 into the arc-shaped grooves 51 and release the driving plate 55. At this time, the elastic force of the spring 6 pushes the clamping blocks 53 to move, so that they are inserted into the clamping holes 54 formed on one side of the arc-shaped plate 5, thereby being able to fix the fixing plate 4. Then rotate the threaded sleeve 42. By using the threaded connection between the threaded sleeve 42 and the threaded block 41, the position of the threaded sleeve 42 can be adjusted to ensure that the bottom of the threaded sleeve 42 can contact the patient's skin when the channel tube 11 and the anti-slip lines 12 are inserted into the abdomen. Then tear off the protective film on the adhesive surface of the adhesive tape 43 and paste the adhesive tape 43 on the patient's skin, thereby being able to fix the channel seat 1, so that the channel tube 11 can maintain better stability after being inserted into the human body, and improve the safety of the operation.
