Description

Technical Field

[0001] The present invention relates to the field of scalp traction surgery, and more particularly to a scalp traction surgery device. Background Art

[0002] Scalp retraction surgery generally refers to a plastic surgery method for scalp laxity or specific scalp problems, especially as part of a facelift such as a facelift, which requires the use of a scalp retractor during the procedure.

[0003] The existing method mainly uses hemostatic forceps to prop up the scalp, and then uses a skull drill to drill a hole for puncture. This method cannot expose the skull puncture point, so it cannot be operated under direct vision; in addition, because the puncture point is in the subcutaneous soft tissue, and the soft tissue is easy to shift and block the puncture point, it is necessary to repeatedly find the puncture point during puncture, which is easy to cause excessive local bleeding and skin tissue damage, and even cause puncture and catheter failure in severe cases. If the skin tissue is damaged, wounds are likely to occur, and the wounds are not easy to heal. In addition to this method, there is another method in the prior art: after expanding the skin incision, the skin is retracted with a mastoid retractor, and then a skull drill is used to drill a hole for puncture and catheterization, and a drainage tube is inserted for drainage. Although this method can fully expose the skull puncture point, it does not achieve the purpose of minimally invasive surgery because the skin incision is too large, and the time for hemostasis and suturing is correspondingly increased, which will increase the patient's pain and the probability of non-healing of the incision.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, a Chinese patent with authorization announcement number CN205054307U discloses a minimally invasive scalp retractor. The device is provided with a direct-viewing window at the front end of the clamp body and a clamp brim at the front end of the clamp body corresponding to the position of the direct-viewing window, so that it is convenient to retract the skin tissue during surgery to expose the puncture point for puncture and drainage, and to compress the skin incision to stop bleeding, thereby reducing tissue damage and improving the success rate of the operation.

[0005] However, in actual surgical operations, the incisions for minimally invasive surgeries in neurosurgery are relatively small, and scalp retractors have been used in the past. However, scalp retractors are relatively large, which can easily obstruct the physician's operation during the precise operation of the surgery. At the same time, the scalp retractor is not easy to adjust the angle during use, and when the retraction distance needs to be adjusted, manual adjustment and continuous support are required, which is rather cumbersome.

At the same time, the bottom connecting plate 508 will move along the surface of the joint ball 504 through the bottom sliding plate 506 during the tilting process, thereby improving the stability of the movement of the bottom connecting plate 508.

[0050] In this embodiment, if Fig. 9 As shown, one end of the side electric push rod 401 is fixedly connected to a bottom limit plate 406, the inner side of the bottom limit plate 406 is fixedly connected to a bottom limit rod 407, the surface of the L connecting block 4010 is fixedly connected to a bottom connecting frame 408, and the surface of the bottom connecting frame 408 is provided with a bottom limit hole 409.

[0053] By synchronously driving the two side electric push rods 401, if it is necessary to adjust the angle of the bottom connecting plate 508 toward one side, the two side electric push rods 401 are respectively in extended and contracted states, and the bottom connecting plate 508 will move and tilt toward the contracted side electric push rod 401, while the side electric push rod 401 on the other side will extend to support one side of the bottom connecting plate 508. At the same time, the bottom connecting plate 508 will move along the surface of the joint ball 504 through the bottom sliding plate 506 during the tilting process, which can improve the stability of the movement of the bottom connecting plate 508.

[0055] After the motor 602 is started, the square socket 603 can be driven by the motor 602 to rotate. The rotation of the square socket 603 will drive the square slider 604 to rotate synchronously. The rotating square slider 604 can drive the bottom connecting rod 605 and the threaded column 606 to rotate. The rotation of the threaded column 606 can synchronously drive the three clamping frames 6016 to move along the bottom of the threaded column 606, and the patient's scalp can be pulled by the pulling block 6017 on one side of the clamping frame 6016.

The outer sleeve hole 6015 and the inner sleeve hole 6011 can be separated by the limiting plate 6014 on the surface of the side connecting rod 6013. The rotation of the threaded column 606 synchronously drives the three clamping frames 6016 to move along the bottom of the threaded column 606, and the patient's scalp can be pulled by the pulling block 6017 on one side of the clamping frame 6016, thereby improving the practicality of the traction.

When the arc block 803 moves, it will drive the arc slider 805 to slide along the inner side of the arc groove 804, and when sliding, it will drive the telescopic rod 80 6 is extended, and through the bottom connecting hole 809 and the fixation of the telescopic rod 806, when the telescopic rod 806 slides along the surface of the side fixing rod 807, it will drive the sliding block 808 to move horizontally synchronously, thereby driving the expansion plate 8011 to move, and the three expansion plates 8011 will be driven to move horizontally synchronously after the three clamping frames 6016 rise, so that the position that needs to be expanded can be portable expanded, and the wound can be kept open without the medical staff using additional tools, thereby improving the practicality of the traction surgery.

[0065] The working process provided by the present invention is as follows:

[0066] When the present invention is in use, the top threaded tube 2 on the top of the top fixing frame 1 can first be threadedly connected to an external mechanical arm or bracket, and the side frame 3 can be connected and fixed to the bracket or mechanical arm by external bolts. The pulling device can be fixed and installed in a portable manner, which improves the stability of the pulling device during pulling and does not require the operator to hold it continuously.

[0067] At the same time, when pulling, first, after the motor 602 is started, the square socket 603 can be driven by the motor 602 to rotate, and the rotation of the square socket 603 will drive the square slider 604 to rotate synchronously. The rotating square slider 604 can drive the bottom connecting rod 605 and the threaded column 606 to rotate, and the three transmission teeth 6012 engaged with the surface of the threaded column 606 will drive the three transmission teeth 6012 to rotate along the surface of the threaded column 606 when the threaded column 606 rotates. During the rotation process, the transmission teeth 6012 will be movably sleeved on the inner side of the inner sleeve hole 6011 through the side connecting rods 6013 on both sides, and the inner sleeve hole 6011 opened on the surface of the side support plate 6010 is used to rotate the side connecting rods 6013. The support limit can maintain the stability of the rotation of the transmission tooth 6012. During the rotation, the transmission tooth 6012 will drive the clamping frame 6016 to rotate synchronously, and the clamping frame 6016 is fixedly sleeved on the surface of the side connecting rod 6013 through the outer sleeve hole 6015. The outer sleeve hole 6015 and the inner sleeve hole 6011 can be separated by the limiting plate 6014 on the surface of the side connecting rod 6013. The rotation of the threaded column 606 synchronously drives the three clamping frames 6016 to move along the bottom of the threaded column 606. The patient's scalp can be pulled by the pulling block 6017 on one side of the clamping frame 6016. At the same time, there is no need for medical staff to continuously pull by hand, which improves the stability of the traction effect and reduces the workload of medical staff.

[0068] At the same time, during the pulling process, after the bottom electric push rod 701 is started, the bottom connecting block 702 will be driven to move vertically, and the bottom connecting block 702 will drive the connecting chassis 703 to adjust its height during the vertical movement. Through the movable socket connection between the inner sliding groove 704 and the inner side groove 706 provided on the surface of the connecting chassis 703, the inner side groove 706 can be driven to move vertically when the connecting chassis 703 moves vertically. The vertical movement of the inner side groove 706 will drive the bottom connecting rod 605, the supporting bottom cylinder 608 and the clamping frame 6016 to move vertically. At the same time, during the movement, the square slider 604 will slide vertically along the inner side of the square socket 603, and when the square socket 603 rotates, it will drive the square slider 604 and The inner side groove 706 rotates, and the bearing slide bar 705 on the surface of the inner side groove 706 slides along the inner side of the inner sliding groove 704, which can reduce the friction caused by the inner side groove 706 rotating along the inner sliding groove 704, and can improve the stability of the vertical movement of the clamping frame 6016 driven by the connecting chassis 703. After the patient's scalp is pulled by the pulling block 6017, the height of the clamping frame 6016 is driven by the bottom electric push rod 701 to adjust the height, which is convenient for fine-tuning the pulling position during the operation. The distance of the pulling device can be adjusted according to the progress of the operation and the patient's reaction to adapt to different surgical stages and different needs of patients, thereby improving the accuracy of the adjustment, and no medical staff need to adjust by hand, which reduces the shaking effect caused by hand-held adjustment.

[0069] After the side electric push rod 401 is started, the side electric push rod 401 can drive the bottom limit plate 406 to move vertically, and the bottom limit rod 407 inside the bottom limit plate 406 is movably connected with the bottom limit hole 409, so that the bottom connecting frame 408 can be driven to move when the bottom limit plate 406 moves, and the connection between the bottom connecting frame 408 and the L connecting block 4010 is driven by the side electric push rod 401 to drive the L connecting block 4010 to tilt at an angle, and the bottom connecting frame 408 will be driven to tilt synchronously during the tilting process, and the inner limit rod 403 is movably connected with the top limit hole 405, so that the bottom of the top connecting frame 404 can be tilted when the side electric push rod 401 moves. At this time, by synchronously driving the two side electric push rods 401, if it is necessary to adjust the angle of the bottom connecting plate 508 to one side At this time, the two side electric push rods 401 are respectively in extended and contracted states, the bottom connecting plate 508 will move and tilt toward the contracted side electric push rod 401, and the side electric push rod 401 on the other side will extend to support one side of the bottom connecting plate 508, and at the same time, the bottom connecting plate 508 will move along the surface of the joint ball 504 through the bottom sliding plate 506 during the tilting process, which can improve the stability of the movement of the bottom connecting plate 508, and at the same time, the sliding inner rail 507 on the surface of the bottom sliding plate 506 slides along the annular rail 505 opened on the surface of the joint ball 504, which can maintain the stability of the bottom connecting plate 508 and the clamping frame 6016 during the tilting process, thereby improving the accuracy of the tilting angle of the bottom connecting plate 508, and can be portable. The angle can be adjusted during the pulling process, thereby improving the versatility of the pulling device.

[0070] After the electric push rod 8010 is started, the expansion plate 8011 can be driven to move vertically downward by adjusting the electric push rod 8010, and the expansion plate 8011 can be moved vertically downward to push the three expansion plates 8011 into the position where expansion is required. At the same time, when the clamping frame 6016 is lifted, the arc block 803 will be driven to move upward synchronously. When the arc block 803 moves, it will drive the arc slider 805 to slide along the inner side of the arc groove 804, and when it slides, it will drive the telescopic rod 806 to extend. Through the bottom connecting hole 809 and the telescopic rod 806, when the telescopic rod 806 slides along the surface of the side fixing rod 807, it will drive the sliding block 808 to move horizontally synchronously, thereby driving the expansion plate 8011 to move. After the three clamping frames 6016 are raised, the three expansion plates 8011 will be driven to move horizontally synchronously, so that the position where expansion is required can be portable expanded, and the wound can be kept open without the medical staff using additional tools, thereby improving the practicality of the traction surgery.
