Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to an adjustable thyroid laparoscopic surgery traction device. Background Art

[0002] During thyroidectomy surgery, a surgical stent is required to pull the surgical site for a long time. During the surgical resection, in order to better provide the surgeon with a field of vision, the probe will be inserted into the patient's wound and the image will be transmitted to the display screen to facilitate the doctor's observation.

[0003] However, in the prior art, when the stent is pulling the surgical site of the patient, since the patients have different body shapes, gauze or other methods are needed to assist in fixing the stent to the connecting rod during the fixing process. This method greatly delays the doctor's time before the operation. In addition, when using a laparoscope for surgery, the doctor needs to hold the laparoscope for a long time during the operation, and the laparoscope is always in an unsupported suspended state during this process. Holding the laparoscope for a long time will make the doctor's hands tired and sore, so the stability of the hand will be reduced. In delicate surgical operations, if the laparoscope is held unsteadily, it will affect the progress of the operation, and in severe cases, it will cause harm to the patient. The traditional stent does not have a supporting effect on the laparoscope, so the use effect is not good. Utility Model Content

[0020] An adjustable thyroid laparoscopic surgery traction device comprises a bracket 101, a pull head 102 is provided on the top of the bracket 101, and a rotating mechanism 300 is fixedly installed on the bottom of the bracket 101; the rotating mechanism 300 is used to carry a probe and provide a rotation angle for the probe.

[0021] Among them, the bracket 101 is a traction bracket commonly used in surgery. A suction tube connector is arranged on the side of the traction bracket. A smoking groove connected to the suction tube connector is arranged at the bottom of the traction bracket. The suction tube connector is used to install a negative pressure suction device. When in use, the smoke generated by the electric knife can be sucked out of the body through the negative pressure suction device connected to the suction tube connector to prevent the smoke from blocking the doctor's line of sight. The pulling head 102 is used to facilitate the traction of the bracket 101. The rotating mechanism 300 is for conveniently carrying the detection probe to provide a surgical field of view for medical staff, and the rotation angle of the probe can be adjusted through the rotating mechanism 300.

[0022] Among them, a suction tube connector is fixedly provided on the side of the bracket 101, and the suction pipeline connected to the suction tube connector is pre-buried in the horizontal retractor hook at the bottom of the bracket 101, and a suction port is opened under the bracket 101, so that the suction tube connector can be connected to the negative pressure suction device during surgery. The smoke generated during the operation can be sucked through the suction port at the bottom of the bracket and discharged from the surgical operation space by the suction pipeline and the suction tube connector, so as to make the surgical field of view clearer.

[0023] Among them, the function of the rotating mechanism 300 is to provide an operating fulcrum for the laparoscope, so as to prevent the doctor from holding the laparoscope in the air for a long time, which may cause hand fatigue and reduce the accuracy. Therefore, in actual use, the rotating mechanism 300 may also adopt a simpler structure such as a wire ring, as long as it can provide an operating fulcrum for the laparoscope. When the wire ring is selected as the operating fulcrum of the laparoscope, it can meet the basic effect of serving as an operating fulcrum. However, since the wire ring has poor stability when suspended, the stability performance of the laparoscope is worse than that of the rotating mechanism 300 in the present application.

[0024] A telescopic mechanism 200 is provided between the bracket 101 and the slider 102 . The telescopic mechanism 200 comprises a frame sleeve 201 , a through hole 202 and an elastic button 203 . A through hole 202 is provided on one side of the frame sleeve 201 , and an elastic button 203 matching the through hole 202 is fixedly installed on one side of the top of the bracket 101 .

[0025] Among them, the telescopic mechanism 200 is used to adjust the height of the pull head 102, so as to facilitate the connection of the pull head 102 with the external traction rod. The frame sleeve 201 is arranged on the outside of the bracket 101. The frame sleeve 201 can slide freely on the outside of the circumference of the bracket 101 by means of sleeve connection, and the cooperation between the through hole 202 and the elastic button 203 can limit the frame sleeve 201 from sliding on the outside of the bracket 101. By pressing the elastic button 203, the elastic button 203 can be snapped into the through hole 202 matched with it, thereby stopping the frame sleeve 201 from sliding, and then achieving the adjustment of the height of the pull head 102, and the pull head 102 and the frame sleeve 201 are fixedly connected.

[0026] The rotating mechanism 300 includes a rotating ball 301 , a rotating seat 302 and a fixed lock 303 . The rotating ball 301 is rotatably mounted inside the rotating seat 302 . A fixed lock 303 is provided on one side of the rotating ball 301 . The fixed lock 303 is used to clamp the probe.

[0027] Among them, the rotation of the rotating mechanism 300 will also drive the probe to move in an angle, so that the probe can be rotated at multiple angles conveniently, making the medical staff's field of vision clearer. A spherical groove matching the rotating ball 301 is provided inside the rotating seat 302, so that the rotating ball 301 can be rotated at a larger angle inside the rotating seat 302. The fixed lock 303 is used to fix the probe to prevent the probe from falling off during the rotation process, thereby better protecting the operation. There are already many types of fixed locks 303 in the prior art, so no excessive elaboration is made. The fixed lock 303 can be fixed by a snap or by a thread.

[0028] It also includes an angle adjustment mechanism 400, which includes a corrugated hose 401, a circular hole 402 and a connecting rope 403. One end of the corrugated hose 401 is fixedly connected to the rotating ball 301, and the other end of the corrugated hose 401 is fixedly connected to the fixed lock 303. Circular holes 402 are provided at four ends inside the corrugated hose 401, and connecting ropes 403 are inserted into the inside of the circular holes 402. One end of the connecting rope 403 is fixedly connected to the fixed lock 303, and the other end of the connecting rope 403 passes through the rotating ball 301.

[0029] Among them, the angle adjustment mechanism 400 is used to offset the probe head at an angle. The probe head is a hard camera, and the connecting line of the probe is soft, so that the probe can be rotated. When the probe is stuck in the fixed lock 303, the angle of the probe can be adjusted by adjusting the corrugated hose 401, so that the probe can obtain more operating fields of view. By pulling the connecting ropes 403 at the four ends, the angle of the probe can be further adjusted, so that the rotation angle of the probe is more diverse, thereby fully meeting the field of view requirements of the physician during surgery.

[0030] It also includes a threaded sleeve 404 and a screw 405 . The threaded sleeve 404 is fixedly mounted on the four ends of the rotating ball 301 . The internal thread of the threaded sleeve 404 is connected to the screw 405 . The screw 405 is rotatably connected to the through end of the connecting rope 403 .

[0031] Among them, in order to facilitate the adjustment of the angle of the probe, a threaded sleeve 404 and a screw 405 are set. By rotating the screw 405, the length of the connecting rope 403 can be reduced, which in turn causes the length of the corrugated hose 401 on the corresponding side to be reduced, thereby causing the corrugated hose 401 to bend, thereby affecting the angle of the probe, thereby achieving the purpose of improving the surgical field of view.

[0032] In the present invention, the pull head 102 can be adjusted to a suitable position by adjusting the telescopic mechanism 200, so that the medical staff can reduce the use of cloth tape during the pulling process, thereby improving the stability during the operation;

[0033] The visual field probe used in the operation is then inserted into the rotating mechanism 300, and the probe is fixed using the fixed lock 303. The inclination angle of the corrugated hose 401 is controlled by the connecting rope 403, thereby achieving the purpose of controlling the probe to tilt at a certain angle.
